Detailed Description
Fig. 1 to 17 described in the following embodiments and the like are schematic diagrams, and the proportions of the size and thickness of each component in fig. 1 to 17 do not necessarily reflect the actual dimensional proportions.
(1) Summary of the invention
The suspended electrical appliance 100 of the present embodiment is used by being attached to a wiring duct 80, and the wiring duct 80 is fixed to, for example, a ceiling of a room of a building or a roof provided outside the building. The building in which the suspended electrical appliance 100 is used may be a non-residential building such as a factory, a school, a shop, a hospital, and an office, or a residential building such as an individual residence and a collective residence.
As shown in fig. 1 to 5, the suspended electrical appliance 100 includes a1 st unit 10 and a 2 nd unit 20, the 1 st unit 10 is attached to a wiring duct 80 and supplied with power from the wiring duct 80, and the 2 nd unit 20 is detachably connected to the 1 st unit 10 and suspended from the 1 st unit 10.
The 1 st unit 10 has a dedicated connection portion 11 for detachably connecting the 2 nd unit 20. The 1 st unit 10 further includes a mounting portion 12 and a1 st unit-side cable (1 st cable portion) 13. The mounting portion 12 is attached to the wiring duct 80 and electrically connected to the conductor 81 of the wiring duct 80. The unit-side cable 131 connects the connection portion 11 and the mounting portion 12. The unit-side cable 113 has an electric wire therein, and the attachment portion 12 and the connection portion 11 are electrically connected via the electric wire of the unit-side cable 113. That is, the unit-side cable 13 of fig. 1 serves as a supply path for supplying power from the mounting portion 12 to the connection portion 11.
Power is supplied from the wiring duct 80 to the 2 nd unit 20 via the connection portion 11 of the 1 st unit 10. The 2 nd unit 20 includes an input section 21 and a function section 22. In addition, the 2 nd unit 20 further includes a 2 nd unit-side cable (2 nd cable part) 23. The input unit 21 is detachably connected to the connection unit 11 of the 1 st unit 10. The 2 nd unit-side cable 23 connects the input unit 21 and the function unit 22. The unit-2 side cable 23 has an electric wire therein, and the input portion 21 and the functional portion 22 are electrically connected via the electric wire of the unit-2 side cable 23. That is, the unit 2-side cable 23 serves as a supply path for supplying electric power from the input unit 21 to the function unit 22.
Electric power is supplied to the function unit 22 from an electric power source connected to the conductor 81 of the wiring duct 80 via the 1 st unit 10 (the mounting portion 12, the 1 st unit-side cable 13, and the connecting portion 11), the input portion 21, and the 2 nd unit-side cable 23. The function unit 22 realizes a predetermined function using the electric power received via the input unit 21.
The function unit 22 of the present embodiment includes a socket body 220 to which a plug (connection target) of an electrical device 301 (see fig. 4) is connected. That is, the function unit 22 of the present embodiment has a function of an Outlet (Outlet) that supplies electric power to the electrical device 301 connected to the Outlet main body 220. Here, the socket body 220 is for ac 100V with a ground. The socket body 220 is a double-mouth socket (a socket having two connection ports 2220 for connecting plugs to be connected) capable of simultaneously connecting two plugs. The electric device 301 connected to the socket main body 220 is not particularly limited, and may be a portable electric device 301 such as a portable computer, or may be an electric device 301 that is difficult to carry, such as an electric tool, a home electric appliance, and a laboratory instrument, which are mounted in a building. That is, the suspended electrical appliance 100 of the present embodiment is a suspended socket that supplies power to the electrical device 301 connected to the socket main body 220.
In the suspended electrical appliance (suspended socket) 100 as described above, when the functional unit 22 (socket main body 220) is used (when the plug of the electrical device 301 is connected to the connection port 2220), the user connects the input unit 21 of the 2 nd unit 20 to the connection unit 11 of the 1 st unit. Thus, the functional unit 22 can be suspended from the mounting portion 12 of the 1 st unit 10, and for example, the functional unit 22 (socket main body 220) can be positioned near the use surface 300 on which the electrical device 301 is provided (see fig. 4).
When the function unit 22 is not used (when the plug is not connected to the connection port 2220 of the socket main body 220), the user detaches the input unit 21 of the 2 nd unit 20 from the connection unit 11 of the 1 st unit 10. Thus, when the function unit 22 (socket main body 220) is not used, the 2 nd unit 20 can be eliminated from the space occupied by the 2 nd unit 20 during use, and the suspension-type electric appliance 100 is less likely to become a factor that limits the range of movement of a person. In addition, this space can be effectively used (see fig. 5).
In fig. 1 and the like, an example is shown in which only 1 suspended electrical appliance 100 is attached to the wiring duct 80, but two or more suspended electrical appliances 100 may be attached to the wiring duct 80.
(2) Detailed description of the invention
Hereinafter, the suspended electrical appliance 100 according to the present embodiment will be described in detail with reference to fig. 1 to 5.
As described above, the suspended electrical appliance 100 of the present embodiment includes the 1 st unit 10 and the 2 nd unit 20.
In the following description, a direction perpendicular to (orthogonal to) a horizontal plane in a state where the 1 st unit 10 is attached to the wiring duct 80 and the 2 nd unit 20 is connected to the 1 st unit 10 is referred to as a "vertical direction", and a downward direction (vertical direction) is referred to as a "downward direction". However, these directions are not intended to limit the use form of the suspended electrical appliance 100.
(2.1) Wiring conduit
First, the wiring duct 80 is explained with reference to fig. 3. The wiring duct 80 is fixed to the ceiling of a room of a building so as to extend along the ceiling surface in the longitudinal direction, for example.
The wiring duct 80 includes a duct main body 82 in addition to the conductor 81.
The duct main body 82 is formed in a flat rectangular cylindrical shape with both ends open, by a metal such as aluminum, and the surface of the duct main body 82 is coated with an insulating synthetic resin. The duct main body 82 has a groove-like connecting recess 821 that opens downward. The connection recess 821 is formed linearly. Lips 822 are provided at lower ends of a pair of inner surfaces of the duct main body 82 facing each other in the width direction of the duct main body 82, respectively. The lip 822 protrudes from the lower end of the corresponding inner surface of the pipe main body 82 toward the inside of the connecting recess 821. That is, the connection recess 821 of the pipe main body 82 is a so-called lip groove.
More specifically, the duct body 82 has an upper wall 823 and two side walls 824. Upper wall 823 constitutes a wall of the upper side of connecting recess 821. Two side walls 824 protrude downward from both ends in the width direction of upper wall 823, respectively, to constitute walls connecting both sides in the width direction of concave portion 821. The connecting recess 821 is open to the lower side and both sides in the longitudinal direction of the duct main body 82. The depth direction of the connecting concave portion 821 when viewed as a groove is the vertical direction, and the back side of the connecting concave portion 821 in the depth direction is the upper side. Each lip 822 protrudes from the lower end of the corresponding side wall 824 toward the inside of the connecting recess 821. Each lip 822 projects parallel to the upper wall 823.
Further, on the inner surface of the connection recess 821 (the surfaces of the two side walls 824 that face each other), a pair of conductor holding portions 825 extending in the longitudinal direction of the pipe main body 82 protrude from the upper side (the back side in the depth direction of the connection recess 821) of the lip portion 822, respectively. A groove-like recess 826 extending in the longitudinal direction of the conductor holding portion 825 is provided on a surface of the pair of conductor holding portions 825 that faces each other (one surface of each conductor holding portion 825 in the width direction of the pipe main body 82). The conductor 81 is received and held in each recess 826.
The structure of the wiring duct 80 to which the suspended electrical appliance 100 is attached is not limited to the illustrated example. For example, the suspended electrical appliance 100 can be attached to an arbitrary wiring duct such as a wiring duct including 3 or more conductors.
(2.2) the 1 st Unit
As described above, the 1 st unit 10 includes the connection portion 11, the attachment portion 12, and the 1 st unit-side cable 13.
As shown in fig. 1 and 3, the connection portion 11 includes a housing 111 and a pair of connection terminals housed in the housing 111.
The housing 111 is made of, for example, a resin material and has electrical insulation. The housing 111 is formed in a cylindrical shape. The housing 111 has a flange at the lower end and a hemispherical protrusion protruding upward on the upper bottom surface side. A pair of connection holes 112 are formed in the lower surface of the housing 111, and corresponding connection terminals are disposed in the back of the connection holes 112. A hole through which the unit-side cable 13 passes is formed at the upper end of the hemispherical protrusion of the housing 111. In addition, a magnet (see fig. 2) as the 1 st coupling portion 110 is accommodated in the housing 111.
As shown in fig. 3, the mounting portion 12 includes a connecting member 121 and a cap member 122.
The connection member 121 includes a cylindrical body 1210, a pair of terminal plates 1211, and a pair of protrusions 1212. The cylindrical body 1210 is formed of, for example, a resin material. The cylindrical body 1210 has electrical insulation. The cylindrical body 1210 is formed in a cylindrical shape (here, a cylindrical shape). The pair of terminal plates 1211 is formed of, for example, a metal material. The pair of terminal plates 1211 has conductivity. The pair of terminal plates 1211 are respectively formed in a plate shape. The pair of terminal plates 1211 protrude from the side surface of the cylindrical body 1210 in the direction perpendicular to the height direction (vertical direction) of the cylindrical body 1210 in the opposite direction to each other. The pair of projections 1212 is formed of, for example, a resin material. The pair of projections 1212 is electrically insulating. The pair of projections 1212 is formed in a plate shape. The pair of protruding portions 1212 protrude from the lower portion of the terminal plate 1211 on the side surface of the cylindrical body 1210 in the direction orthogonal to the height direction of the cylindrical body 1210 in the opposite direction to each other. The pair of protruding portions 1212 protrude in parallel with the pair of terminal plates 1211, respectively.
The cap member 122 is formed of, for example, a resin material into a hollow cylindrical shape which tapers toward the lower tip. The connection member 121 is connected to the upper surface of the cap member 122, and a hole through which the unit-side 1 cable 13 passes is formed in the center of the lower surface of the cap member 122.
The 1 st unit-side cable 13 is formed of a flexible cord, for example, a vinyl circular cord (VRF, VSRF). The cord includes the electric wire (a pair of power supply wires) and a sheath covering the electric wire and formed of an insulating material. The 1 st unit-side cable 13 has a1 st end 131 and a 2 nd end 132. The 1 st end 131 of the 1 st unit-side cable 13 is connected to the connection portion 11, and the 2 nd end 132 of the 1 st unit-side cable 13 is connected to the attachment portion 12. The 1 st ends of the pair of power cords of the cord are connected to the corresponding connection terminals in the housing 111 of the connection portion 11, respectively. The 2 nd ends of the pair of power cords of the cord are connected to the corresponding terminal blocks 1211 of the connecting member 121 of the mounting portion 12, respectively.
In the unit 110, the connection portion 11 is suspended from the attachment portion 12 via the unit 1-side cable 13 in a state where the attachment portion 12 is attached to the wiring duct 80. In addition, in a state where the mounting portion 12 is mounted to the wiring duct 80, the terminal plate 1211 of the mounting portion 12 is electrically connected to the conductor 81 of the wiring duct 80. This enables power to be supplied to connection unit 11 from a power source connected to conductor 81 of wiring duct 80.
(2.3) the 2 nd unit
The 2 nd unit 20 includes an input section 21, a function section 22, and a 2 nd unit-side cable 23.
As shown in fig. 1 and 3, the input section 21 includes a housing 211 and a pair of connection pins 212.
The housing 211 is formed of, for example, a resin material, and has electrical insulation. The housing 211 is formed in a cylindrical shape. The housing 211 has a flange at the upper end and a hemispherical protrusion protruding downward on the lower bottom surface side. A pair of connection pins 212 protrude from the upper surface of the housing 211. The interval between the pair of connection pins 212 of the input unit 21 is substantially the same as the interval between the pair of connection holes 112 of the connection unit 11 of the 1 st unit 10. A hole through which the unit 2 side cable 23 passes is formed at the lower end of the hemispherical protrusion of the housing 211. In addition, a magnetic body (see fig. 2) serving as the 2 nd coupling portion 210 is accommodated in the housing 211. The 2 nd coupling part 210 can be coupled to the 1 st coupling part 110 accommodated in the case 111 of the connection part 11 of the 1 st unit 10 by magnetic force.
In the present embodiment, the functional unit 22 is the socket main body 220. The socket main body 220 includes a housing 221 and a socket portion 222, and the socket portion 222 is received in the housing 221.
The case 221 is made of synthetic resin, and is made of ABS resin as an example. The casing 221 has a "longitudinal" shape elongated in one direction (vertical direction in fig. 1), and is flat in one direction (thickness direction) in a plane orthogonal to the longitudinal direction. The housing 221 is connected to the 2 nd unit-side cable 23 at the 1 st end 2211 in the longitudinal direction. The case 221 has a tapered shape such that the thickness and width of the case decrease as it approaches the 1 st end 2211 from the 2 nd end 2212 in the longitudinal direction. The housing 221 is formed so as to be continuous from the 2 nd end 2212 to the 1 st end 2211 without steps, so-called "one-motion form". Specifically, the outer peripheral surface of the casing 221 is gently curved so as to protrude outward from the 2 nd end 2212 to the middle portion in the longitudinal direction, and gently curved so as to protrude inward from the middle portion in the longitudinal direction to the 1 st end 2211. Further, the outer peripheral surface of the housing 221 is a curved surface that continues without a step over the entire circumference, as viewed in a direction parallel to the longitudinal direction. The surface of the case 221 is formed of an embossed surface (embossed surface). The "embossing" is a process of applying a fine uneven wrinkle pattern (embossing) to the surface of the casing 221 when the casing 221 is formed.
The housing body 2213 and the cover 2214 are combined to form the housing 221. The body 2213 and the cover 2214 have openings at the sides opposite to each other, respectively, and the body 2213 and the cover 2214 are coupled together by aligning the openings with each other. Thus, an internal space for accommodating the socket portion 222 and the like is formed between the body 2213 and the cover 2214. The body 2213 and the cover 2214 are temporarily fixed together, for example, by hooking a plurality of engaging claws protruding from the inner peripheral edge of the opening of one of the body 2213 and the cover 2214 to a plurality of engaging holes formed in the inner peripheral edge of the opening of the other of the body 2213 and the cover 2214. In this state, the body 2213 and the cover 2214 are combined together by fastening a plurality of combining screws through one of the body 2213 and the cover 2214 to the other.
An introduction hole through which the 2 nd unit-side cable 23 is passed is formed at the 1 st end 2211 of the housing 221. The introduction hole is a circular hole formed in the end surface of the 1 st end 2211 of the housing 221. In the present embodiment, a pair of semicircular notches formed in the housing 2213 and the cover 2214 are aligned to form a circular inlet hole.
In addition, an opening 2216 for exposing the socket portion 222 is formed at the 2 nd end 2212 of the housing 221. The opening 2216 is a hole penetrating the wall of the case 221 on the 2 nd end 2212 side, and is formed in a rectangular shape long in the width direction of the case 221. The opening 2216 may be formed in a side surface of the housing 221, for example.
Further, the housing 221 has a pair of hooks 2217 (only 1 is illustrated in fig. 1 and 3) protruding from the surface of the housing 2213 on the side opposite to the cover 2214. The pair of hooks 2217 is a configuration in which power supply hoses extending from the plugs of the electrical equipment 301 are hung. Thus, in the suspended electrical appliance 100, in a state where the plug is connected to the socket main body 220, the hook 2217 can receive a load applied to the plug by the own weight of the power cord or the like.
The socket portion 222 includes a housing 2221 made of synthetic resin and a built-in component such as a cutter holder member housed in the housing 2221. The socket portion 222 is housed in the housing 221 so that one surface (connection surface) 2222 of the housing 2221 is exposed from the opening 2216. Two connection ports 2220 into which plugs (or pins) of the plugs are inserted are formed in the connection surface 2222. The socket portion 222 has a retaining mechanism that prevents a plug (or pin) of the plug from coming off by rotating the plug.
The 2 nd unit-side cable 23 is formed of a flexible cord, for example, a circular vinyl cord. The cord includes the electric wire (a pair of power supply wires) and a sheath covering the electric wire and formed of an insulating material. The 2 nd unit-side cable 23 has a1 st end 231 and a 2 nd end 232. The 1 st end 231 of the 2 nd unit-side cable 23 is connected to the function unit 22 (the socket main body 220), and the 2 nd end 232 of the 2 nd unit-side cable 23 is connected to the input unit 21. The 1 st end of the cord is introduced into the housing 221 of the receptacle main body 220 through the introduction hole, and is branched into two branched cords in the housing 221. Each branch cord is connected to a terminal portion (so-called quick-connect terminal) of a corresponding connection port 2220 of the two connection ports 2220. The 2 nd end (of the pair of power cords) of the cord is connected to a connection pin 212 in the housing 211 of the input section 21.
(2.4) installation of the 1 st Unit to the Wiring duct
As shown in fig. 1, the 1 st unit 10 is attached to the wiring duct 80 by attaching the attachment portion 12 to the wiring duct 80.
For example, the mounting portion 12 is first positioned below the wiring duct 80 so that the protruding direction of the pair of protruding portions 1212 of the connecting member 121 coincides with the longitudinal direction of the connecting recess 821 (the longitudinal direction of the duct main body 82). Then, after the pair of projections 1212 is inserted into the connecting recess 821 from below, the mounting portion 12 is rotated by 90 degrees about the axis of the cylindrical body 1210. Thus, the protrusion 1212 is inserted into the gap between the lip 822 of the pipe main body 82 and the conductor holding portion 825, and the protrusion 1212 is held between the lip 822 and the conductor holding portion 825. The terminal plate 1211 is inserted into the recess 826 of the conductor holding portion 825, and the terminal plate 1211 is connected to the conductor 81. In the above-described procedure, the 1 st unit 10 can be attached to an arbitrary position in the longitudinal direction of the wiring duct 80.
In order to facilitate the attachment of the attachment portion 12 to the wiring duct 80, the attachment portion 12 may include a rotation assisting mechanism that rotates the connecting member 121 (about the axis of the cylindrical body 1210) with respect to the cap member 122 in response to a button operation, a lever operation, or the like.
When the 1 st unit 10 is detached from the wiring duct 80, the procedure opposite to the procedure at the time of attachment may be performed. That is, after the mounting portion 12 is rotated 90 degrees about the axis of the cylindrical body 1210 to remove the protruding portion 1212 from between the lip portion 822 and the conductor holding portion 825, the mounting portion 12 may be pulled out from the connecting recess 821.
(2.5) connection of the 2 nd Unit to the 1 st Unit
In the suspended electrical appliance 100 of the present embodiment, the pair of connection pins 212 of the input unit 21 are connected to the pair of connection terminals of the connection unit 11 by inserting the pair of connection pins 212 of the input unit 21 into the pair of connection holes 112 of the connection unit 11. Thereby, (the input portion 21 of) the 2 nd unit 20 is electrically connected to (the connection portion 11 of) the 1 st unit 10 (see fig. 2). At this time, the 1 st coupling part 110 (magnet) of the connecting part 11 and the 2 nd coupling part 210 (magnetic body) of the input part 21 are coupled to each other by magnetic force, and the positional relationship between the 1 st unit 10 and the 2 nd unit 20 is maintained by magnetic force.
The connection unit 11 is configured to be electrically and mechanically connected exclusively (only) to the input unit 21 of the 2 nd unit 20.
For example, the connecting portion 11 has a configuration that it cannot connect with a general-purpose plug (JIS C8303 plug, NEMA1-15 plug, NEMA5-15 plug, BS1363 plug, CPCS-CCC plug or AS/NZS3112 plug, BS546 plug, BS4573 plug, CEE7/4 plug, CEE7/5 plug, CEE7/17 plug, 107-2-D1 plug, CEI23-16/VII plug, SEV1011 plug, IEC60906-1 plug, TIS166-2549 plug, CEE7/4 plug, AS/NZS3112 plug, etc.). For example, the shape of the connection hole 112 may be different from the shape of a male connector (plug or pin) of the plug, and the interval between the pair of connection holes 112 may be different from the interval between the pair of male connectors of the plug. The distance between the lower surface (connection hole 112) of the housing 111 and the connection terminal may be longer than the length of the male connector of the general-purpose plug. Further, a concave-convex structure that fits together when the connection pin 212 is inserted into the connection hole 112 may be formed on the lower surface of the housing 111 of the connection unit 11 and the upper surface of the housing 211 of the input unit 21.
(2.6) example of use
As described above, the 1 st unit 10 is attached to the wiring duct 80 by attaching the attachment portion 12 to the wiring duct 80. Further, the 2 nd unit 20 is connected to the 1 st unit 10 by connecting the input portion 21 to the connection portion 11 of the 1 st unit 10. At this time, the functional unit 22 (socket main body 220) is electrically connected to the conductor 81 of the wiring duct 80 via the 1 st unit 10, the input unit 21, and the 2 nd unit-side cable 23. That is, electric power can be supplied to the functional unit 22 from an electric power source (e.g., a commercial power source) connected to the wiring duct 80. In the present embodiment, since the function unit 22 is the socket main body 220, electric power can be supplied to the electric device 301 connected to the connection port 2220 of the socket main body 220 (see fig. 4).
On the other hand, when the function unit 22 (2 nd unit 20) is not used, the user detaches the input unit 21 from the connection unit 11. Thus, when the function unit 22 is not used, the 2 nd unit 20 is not distracted or prevented from moving while being in the field of view. That is, when the functional unit 22 is not used, the suspended electric appliance 100 is not likely to be a factor that limits the range of motion of a person. In addition, the user can freely use the space occupied by the 2 nd unit 20 when the 2 nd unit 20 is connected to the 1 st unit 10 (see fig. 5).
(3) Modification example
The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment is only required to achieve the purpose of cost disclosure, and various modifications can be made depending on design and the like. Modifications of the above embodiment will be described below. Hereinafter, the above-described embodiment will be referred to as "basic example". The modifications and basic examples described below can be combined and applied as appropriate.
(3.1) variation 1
A suspension-type electric appliance 100 according to modification 1 will be described with reference to fig. 6A and 6B. The suspended electrical device 100 of the present modification differs from the suspended electrical device 100 of the basic example mainly in that it further includes the lock mechanism 3. The lock mechanism 3 is a mechanism capable of switching between a locked state in which the 1 st unit 10 and the 2 nd unit 20 are mechanically coupled so that power is supplied to the input unit 21 via the connection unit 11, and a released state in which the coupled state can be released.
The lock mechanism 3 of the present modification includes a holding plate member 31 rotatably attached to the housing 111 of the connection portion 11. The holding plate member 31 includes a1 st plate portion 311, a 2 nd plate portion 312, and a shaft portion 313, the 1 st plate portion 311 being rectangular, the 2 nd plate portion 312 protruding from the 1 st plate portion 311 in a thickness direction of the 1 st plate portion 311, and the shaft portion 313 holding the 1 st plate portion 311 rotatably with respect to the housing 111.
The 1 st plate portion 311 is formed of, for example, a resin material into a rectangular plate shape that is long in one direction. The 1 st plate portion 311 includes a cylindrical bearing portion at the 1 st end thereof, the axial direction of which is along the width direction (short side direction) of the 1 st plate portion 311. The 2 nd plate portion 312 protrudes from the 2 nd end of the 1 st plate portion 311 in the thickness direction of the 1 st plate portion 311 (the direction perpendicular to the longitudinal direction and the width direction of the 1 st plate portion 311). The holding plate member 31 is formed in an L-shape in side view by the 1 st plate portion 311 and the 2 nd plate portion 312. The center of the projecting end of the 2 nd plate 312 is notched in a U-shape to form a cable receiving portion 314. The shaft portion 313 holds the bearing portion of the 1 st plate portion 311 to be rotatable about the axial direction thereof. Here, the housing 111 of the connection portion 11 has a flat surface portion 113 parallel to a vertical surface at a lower portion of a side surface thereof. The shaft portion 313 is fixed to the flat portion 113 so as to extend axially along the flat portion 113 and the horizontal plane. The holding plate member 31 is transitionable between a1 st state (see fig. 6A) in which the longitudinal direction of the 1 st plate portion 311 intersects with the axial direction of the cylindrical housing 111 (intersects with the flat portion 113) and a 2 nd state (see fig. 6B) in which the longitudinal direction of the 1 st plate portion 311 is along the axial direction of the housing 111 (along the flat portion 113).
The housing 211 of the input unit 21 has a flat surface 213 on a side surface thereof, the flat surface being parallel to a vertical plane.
As shown by the arrows in fig. 6A, the input portion 21 of the 2 nd unit 20 is moved upward toward the connection portion 11 of the 1 st unit 10, the pair of connection pins 212 are inserted into the pair of connection holes 112, and the holding plate member 31 is rotated so that the holding plate member 31 is in the 2 nd state. Thereby, the 2 nd end 232 of the 2 nd unit-side cable 23 is fitted into the cable receiving portion 314 of the holding plate member 31. At this time, the upper surface (surface on the 1 st plate portion 311 side) of the 2 nd plate portion 312 contacts the lower portion (tip of the projection of the housing 211) of the housing 211. That is, the state (locked state) in which the 1 st unit 10 and the 2 nd unit 20 are mechanically coupled is held by the 2 nd plate portion 312 of the holding plate member 31 (see fig. 6B). On the other hand, when the holding plate member 31 is rotated to bring the holding plate member 31 into the 1 st state, the state in which the 1 st unit 10 and the 2 nd unit 20 are mechanically coupled is released (released state).
Since the suspension-type electric appliance 100 of the present modification includes the lock mechanism 3, the possibility that the 2 nd unit 20 is inadvertently detached from the 1 st unit 10 can be reduced.
As shown in fig. 6A, a ridge 315 may be formed on one of the lower bottom surface of the housing 111 of the connection portion 11 and the upper bottom surface of the housing 211 of the input portion 21, and a groove 316 may be formed on the other. The projection 315 is shaped to fit into the groove 316 when the connection pin 212 is inserted into the connection hole 112. With this structure, when the connection pin 212 is inserted into the connection hole 112, rotation of the input portion 21 with respect to the connection portion 11 (rotation about the axial direction of the cylindrical housing 211) is suppressed, and mechanical coupling between the connection portion 11 and the input portion 21 can be further strengthened.
In this modification, the holding plate member 31 may be provided in the housing 211 of the input unit 21.
(3.2) variation 2
A suspension-type electric appliance 100 according to modification 2 will be described with reference to fig. 7. The suspended electrical appliance 100 of the present modification is different from the suspended electrical appliance 100 of the 1 st modification in that the structure of the lock mechanism 3 is different.
The lock mechanism 3 of the present modification includes a snap structure 32. The snap structure 32 includes a male half 321 provided in the connecting portion 11 and a female half 322 provided in the input portion 21.
A pair of flat portions 113 is formed in a portion of the connecting portion 11 below the side surface of the housing 111. A flexible variable plate 114 made of, for example, leather is attached to each flat surface portion 113. The male half 321 is provided on the variable plate 114. Further, a pair of flat surface portions 213 are formed in an upper portion of the side surface of the housing 211 of the input unit 21. The female half 322 is provided on each flat surface 213.
In a state where the pair of connection pins 212 are inserted into the pair of connection holes 112, when the male half 321 and the female half 322 are coupled to each other as shown by a solid line in fig. 7, a state where the 1 st unit 10 and the 2 nd unit 20 are mechanically coupled (locked state) is maintained. On the other hand, as shown by the broken line in fig. 7, when the coupled state of the male half 321 and the female half 322 is released, the mechanically coupled state (released state) of the 1 st unit 10 and the 2 nd unit 20 is released.
Since the suspension-type electric appliance 100 of the present modification includes the lock mechanism 3, the possibility that the 2 nd unit 20 is inadvertently detached from the 1 st unit 10 can also be reduced.
In the present modification, the female half 322 may be provided in the housing 111 of the connection unit 11, and the variable plate including the male half 321 may be provided in the housing 211 of the input unit 21. The female half may be provided on the variable plate and the male half may be provided on the housing. The snap structure 32 includes two sets of male and female halves, but may include 1 set or 3 sets or more.
(3.3) variation 3
A suspension-type electric appliance 100 according to modification 3 will be described with reference to fig. 8. The suspended electrical appliance 100 of the present modification is different from the suspended electrical appliance 100 of the 1 st modification in that the structure of the lock mechanism 3 is different.
The lock mechanism 3 of the present modification includes an engagement projection 33 of the tool receiver 115 provided on the connection terminal of the connection portion 11.
As shown in fig. 8, in the present modification, each of the pair of connection holes 112 of the connection portion 11 is formed in an arc shape. Further, at each of the arc-shaped connection holes 112, a pair of blades 115 are arranged so as to face each other at the position of the back of the clockwise distal end edge of the housing 111. The pair of tool holders 115 are provided with engagement protrusions 33, respectively, and the engagement protrusions 33 are bent and engaged in a V-shape in the middle in the longitudinal direction. The engagement protrusions 33 of the pair of cutters 115 protrude in directions facing each other.
In the present modification, the pair of coupling pins 212 are inserted into the pair of coupling holes 112, and the input portion 21 is rotated in the clockwise direction, so that the coupling pins 212 are caused to pass over the engagement protrusions 33 while pushing the gap between the pair of tool holders 115 open. Thereby, the connection pin 212 is inserted into the space of the housing 111 surrounded by the edge of the connection hole 112 and the pair of engagement protrusions 33, and the connection pin 212 is elastically held by the edge of the connection hole 112 and the pair of engagement protrusions 33.
Since the suspended electrical device 100 of the present modification includes the lock mechanism 3, the possibility that the 2 nd unit 20 is inadvertently detached from the 1 st unit 10 can be reduced.
In this modification, the lock mechanism 3 may be configured by a through hole penetrating the connection pin 212 in one radial direction and a projection provided on the tool holder 115 and engaged with the through hole of the connection pin 212, similarly to the structure of the so-called anti-slip socket.
(3.4) the 4 th modification
A suspension-type electric appliance 100 according to a 4 th modification will be described with reference to fig. 9A to 9C. The suspended electrical appliance 100 of the present modification is different from the suspended electrical appliance 100 of the first modification 1 in that the structure of the lock mechanism 3 is different.
The lock mechanism 3 of the present modification includes a cylindrical cap 34. The cap 34 has a cylindrical shape with an inner diameter slightly larger than the outer diameter of the housing 111 of the connection part 11, a hemispherical bottom surface on the upper side, and an opening on the lower side. A hole through which the 1 st unit-side cable 13 is inserted is formed in the bottom surface of the cap 34 on the upper side. The unit-side cable 131 is inserted through the hole in the bottom surface on the upper side, and the cap 34 is disposed between the connection portion 11 and the attachment portion 12 so as to open toward the connection portion 11 side and the bottom surface toward the attachment portion 12 side. The cap 34 is movable along the 1 st unit-side cable 13 between the 1 st end 131 and the 2 nd end 132 (see fig. 1) of the 1 st unit-side cable 13.
As shown in fig. 9A, a spiral groove 341 is formed on the inner surface of the cap 34. As shown in fig. 9A and 9B, spiral projections 342 and 343 are formed on the side surface of the housing 111 of the connection portion 11 and the side surface of the housing 211 of the input portion 21 so as to be continuous with the connection pin 212 inserted into the connection hole 112.
As shown by the arrows in fig. 9A, the input portion 21 of the 2 nd unit 20 is moved upward toward the connection portion 11 of the 1 st unit 10 to insert the pair of connection pins 212 into the pair of connection holes 112, and as shown by the arrows in fig. 9B, when the cap 34 is rotated while the cap 34 is pushed downward, the cap 34 is gradually moved downward while the concave groove 341 is moved along the spiral ridges 342 and 343. That is, the state (locked state) in which the 1 st unit 10 and the 2 nd unit 20 are mechanically coupled is maintained by fitting the spiral protrusion 343 of the input unit 21 into the spiral groove 341 of the cap 34 (see fig. 9C). On the other hand, when the cap 34 is rotated in the direction opposite to the coupling direction, the mechanically coupled state (released state) of the 1 st unit 10 and the 2 nd unit 20 is released.
Since the suspension-type electric appliance 100 of the present modification includes the lock mechanism 3, the possibility that the 2 nd unit 20 is inadvertently detached from the 1 st unit 10 can also be reduced.
In the present modification, each of the protrusions 342 and 343 may not be a continuous 1-piece protrusion, but may be formed of a plurality of protrusions formed along a spiral virtual line. The cap 34 may be provided on the 2 nd unit 20 side.
(3.5) variation 5
A suspension-type electric appliance 100 according to a modification example 5 will be described with reference to fig. 10. The suspended electrical appliance 100 of the present modification is different from the suspended electrical appliance 100 of the basic example mainly in that the structure of the mounting portion 12 is different, and in that the 1 st unit 10 includes a connection cable (connection cable portion) 14 instead of the 1 st unit-side cable 13.
In the suspended electrical appliance 100 of the present modification, the mounting portion 12 includes the lateral rotation member 123 instead of the cap member 122.
The lateral rotating member 123 includes a rotating body 1230, a1 st supporting body 1231, and a 2 nd supporting body 1232. The rotating body 1230 is formed in a cylindrical shape from, for example, a resin material. The 1 st support body 1231 is formed, for example, of a resin material into a bottomed cylindrical shape, and is disposed above the rotating body 1230 such that the bottom surface thereof is located above. The connection member 121 is connected to the bottom surface (upper surface) of the 1 st support 1231. The 2 nd support body 1232 is formed, for example, of a resin material into a bottomed cylindrical shape, and is disposed below the rotating body 1230 such that the bottom surface thereof is located below. The 1 st support body 1231 and the 2 nd support body 1232 are disposed vertically above and below the rotating body 1230 with the rotating body 1230 interposed therebetween. Support 1231 and support 1232 are secured to each other. The 1 st support body 1231 and the 2 nd support body 1232 hold the rotating body 1230 so that the rotating body 1230 can rotate about the axis of the cylindrical rotating body 1230. The arrows labeled dotted shading of fig. 10 indicate the direction of rotation of the rotating body 1230. However, the rotation range of the rotating body 1230 is not limited to the range of the arrow marked with dotted hatching, and the rotating body 1230 may be rotated to an arbitrary angle around the axis of the rotating body 1230 (that is, the movable range of the rotating body 1230 is 360 °).
The connection cable 14 is connected (held) to the rotating body 1230 and rotates together with the rotating body 1230. The connection cable 14 is held to the rotating body 1230 in such a manner as to protrude from the side of the rotating body 1230 in a radial direction of the rotating body 1230. That is, the lateral rotation member 123 holds the 1 st end 141 of the connection cable 14 so that the connection cable 14 is positioned in a plane orthogonal to a suspension direction (vertical direction) in which the 2 nd unit 20 is suspended from the 1 st unit 10. Then, by rotating the rotating body 1230, the connection cable 14 is rotated in a plane orthogonal to the suspension direction. The connection portion 11 is connected to the 2 nd end 142 of the connection cable 14.
In the present modification, the connection cable 14 includes the outer shell 140. Profile 140 includes a1 st profile 1401 and a 2 nd profile 1402. The 1 st and 2 nd profiles 1401 and 1402 are, for example, tubes made of metal such as stainless steel, and the surfaces of the 1 st and 2 nd profiles 1401 and 1402 are coated with insulating synthetic resin. The 1 st profile 1401 and the 2 nd profile 1402 each have at least a degree of rigidity capable of supporting the connection portion 11 in the plane. The 1 st and 2 nd profiles 1401 and 1402 are cylindrical, respectively. The outer diameter of the 2 nd profile 1402 is slightly smaller than the inner diameter of the 1 st profile 1401. The 1 st profile 1401 is located on the 1 st end 141 side of the profile 140, and the 2 nd profile 1402 is located on the 2 nd end 142 side of the profile 140. The framework 140 is constructed in a one-piece tubular shape by inserting a portion of the 2 nd framework 1402 into the 1 st framework 1401. In the present modification, the length of the framework 140 (the length of the connection cable 14) can be adjusted by changing the amount of insertion of the 2 nd framework 1402 into the 1 st framework 1401. In addition, the connection cable 14 further comprises a fixing tool 143, and the fixing tool 143 is used for fixing the relative positions of the 1 st profile 1401 and the 2 nd profile 1402. The fixing means 143 are here thumb screws. A screw hole is provided at an end of the 1 st outline 1401 on the 2 nd outline 1402 side. By screwing the fixture 143 into the screw hole, the tip of the fixture 143 is brought into contact with the outer surface of the 2 nd profile 1402, and the relative positions of the 1 st profile 1401 and the 2 nd profile 1402 can be fixed.
In the present modification, the 1 st profile 1401, the 2 nd profile 1402, and the fixture 143 constitute a length adjustment mechanism for adjusting the length of the connection cable 14.
The cords containing the wires pass within the outer shell 140 of the connecting cable 14. The 1 st ends of the pair of wires of the cord are connected to the corresponding connection terminals in the housing 111 of the connection portion 11, respectively. A pair of wires of the cord pass through the outer shell 140 of the connection cable 14 and the rotating body 1230, respectively, and the 2 nd ends thereof are connected to the corresponding terminal blocks 1211 of the connection member 121.
In suspended electric appliance 100 according to the present modification, by rotating body 1230 relative to first support 1231 and second support 1232, the position of connection portion 11 can be adjusted in a plane (horizontal plane) orthogonal to the suspension direction. That is, the position of the functional section 22 of the 2 nd unit 20 connected to the connection section 11 can be adjusted in a plane (horizontal plane) orthogonal to the suspension direction.
As shown in fig. 11, the suspended electrical appliance 100 of the present modification may further include the 1 st unit-side cable 13. In this case, the 1 st unit-side cable 13 is provided between the 2 nd end 142 of the connection cable 14 and the connection unit 11. The 1 st end 131 of the 1 st unit-side cable 13 is connected to the connection unit 11, and the 2 nd end 132 is connected to the 2 nd end 142 of the connection cable 14. For example, the 1 st unit-side cable 13 is a part of the cord passing through the inside of the outer frame 140 of the connection cable 14. The cord passes within the profile 140. The wires of the cord are electrically insulated from the profile 140 by the sheath. In this case, the position of the functional unit 22 of the 2 nd unit 20 connected to the connection unit 11 can be adjusted in a plane (horizontal plane) orthogonal to the suspension direction. In addition, the arrow labeled as dot hatching of fig. 11 indicates the direction of rotation of the rotating body 1230. However, the rotation range of the rotating body 1230 is not limited to the range of the arrow marked with dotted hatching, and the rotating body 1230 may be rotated to an arbitrary angle around the axis of the rotating body 1230 (that is, the movable range of the rotating body 1230 is 360 °). The 1 st unit-side cable 13 may have an outer profile in the same manner as the connection cable 14, or may have a length adjustment mechanism (1 st outer profile, 2 nd outer profile, and fixing tool).
In the present modification, the lateral rotation member 123 may include a temporary position fixing mechanism (a gear mechanism, for example, a ratchet mechanism) capable of fixing the rotational position of the rotating body 1230 at predetermined angular intervals (for example, at intervals of 5 °).
(3.6) variation 6
A suspension-type electric appliance 100 according to modification 6 will be described with reference to fig. 12. The suspended electrical equipment 100 of the present modification is different from the suspended electrical equipment 100 of the basic example mainly in the structure of the mounting portion 12.
In the suspended electrical appliance 100 of the present modification, the mounting portion 12 includes the winding member 124 instead of the cap member 122. The winding member 124 includes, for example, a housing 1241, a reel, a release button 1242, and a winding spring as a coil spring.
The housing 1241 is formed of, for example, a resin material into a cylindrical shape having a housing space 1240 therein. The housing 1241 has a planar portion at a part (upper part) of the cylindrical side surface, and the connection member 121 is connected to this portion. A through hole 1243 through which the 1 st unit-side cable 13 is passed is formed in a portion of the side surface of the cylindrical case 1241 apart from the flat portion. The spool is received within the housing 1241. A part of the unit-side cable 13 on the mounting portion 12 side (the part of the 2 nd end 132) is stored in the storage space 1240 of the housing 1241 so as to be wound around a reel.
The direction of rotation of the reel is restricted by the ratchet mechanism so that only the 1 st unit-side cable 13 can be paid out, and when the 1 st unit-side cable 13 is pulled, the 1 st unit-side cable 13 is pulled out from the housing space 1240 of the housing 1241. When the release button 1242 is operated in a state where the 1 st unit-side cable 13 is pulled out, the restriction by the ratchet mechanism is released, and the reel is rotated in a direction in which the 1 st unit-side cable 13 is wound by the restoring force applied to the reel from the winding spring.
That is, in the present modification, the mounting portion 12 has a housing space 1240 for housing a portion of the unit-side cable 13 on the mounting portion 12 side so that the portion can be inserted and removed.
In the present modification, a portion of the unit-side cable 13 on the side of the mounting portion 12 can be housed in the housing space 1240 of the housing 1241 of the winding member 124. Therefore, when the function unit 22 is not used, the length of the unit-side cable 13 can be shortened, and when the function unit 22 (the 2 nd unit 20) is not used, the possibility that the suspension-type electric appliance 100 restricts the range of movement of a person can be further reduced.
In the present modification, the reel, the winding spring, and the release button (and the ratchet mechanism and the housing space) may be provided in the connection portion 11, or may be provided in the input portion 21 or the function portion 22 (the socket main body 220).
(3.7) 7 th modification
A suspension-type electric appliance 100 according to a modification example of fig. 7 will be described with reference to fig. 13. The suspended electrical appliance 100 of the present modification is different from the suspended electrical appliance 100 of the basic example mainly in that the structures of the attachment portion 12 and the unit-side cable 13 of fig. 1 are different and the holding body 9 is further included.
As shown in fig. 13, in the present modification, the 1 st-unit-side cable 13 includes a shell 130.
The outer shell 130 is a metal pipe such as stainless steel, and the surface of the outer shell 130 is coated with an insulating synthetic resin. The outer shell 130 is cylindrical. The outer frame 130 has a rigidity of a predetermined value or more. For example, the outer profile 130 has a rigidity to the extent that it does not flex when the 1 st unit 10 is held by the holding body 9. Preferably, the bending stiffness and the torsional stiffness of the profile 130 are relatively large. A cord comprising wires and sheaths is passed within the profile 130. The wires of the cord are electrically insulated from the outer shell 130 by the sheath.
The mounting portion 12 includes an arm member 125 instead of the cap member 122.
The arm member 125 includes a1 st arm 1251, a 2 nd arm 1252, an arm-side cable 1253, a1 st spring 1254, and a 2 nd spring 1255.
The 1 st arm 1251 is formed of, for example, a metal material. The 1 st arm 1251 is formed in an inverted U shape in side view by a pair of side plates (1 st arm side plate) and a top plate. The top plate is a rectangular plate having a hole in the center through which the arm-side cable 1253 passes, and is coupled to the lower surface of the cylindrical body 1210 (see fig. 3) of the connecting member 121. The pair of side plates are each in the form of a rectangular plate having a semicircular tip, and project in the thickness direction of the top plate so as to face each other. Through holes (1 st through hole) are formed in the tip portions of the pair of side plates, respectively. Semicircular plate-shaped support plate portions are formed on the base end portions (top plate side portions) of the pair of side plates so as to protrude in the width direction of the side plates, respectively. Further, cylindrical engaging portions (1 st engaging portion) project outward from the support plate portions.
The 2 nd arm 1252 is formed of, for example, a metal material. The 2 nd arm 1252 is formed into a U shape in side view by a pair of side plates (2 nd arm side plates) and a bottom plate. The base plate has a rectangular plate shape, the lower surface of which is joined to the 2 nd end 132 of the 1 st unit-side cable 13, and the cord of the 1 st unit-side cable 13 is inserted through a hole formed in the center of the base plate. The pair of side plates are each in the form of a rectangular plate having a semicircular tip, and project in the thickness direction of the base plate so as to face each other. Through holes (2 nd through holes) are formed in the tip portions of the pair of side plates, respectively. Cylindrical engaging portions (2 nd engaging portions) protrude outward from base end portions (portions on the bottom plate side) of the pair of side plates, respectively.
The arm-side cable 1253 is a part of the flexible cord. The pair of power supply lines of the arm-side cable 1253 are connected to the corresponding terminal blocks 1211 in the tubular body 1210 of the connecting member 121.
The 1 st through hole and the 2 nd through hole are overlapped, the bushing is inserted through the 1 st through hole and the 2 nd through hole, the bolt is inserted through the bushing, and the nut and the bolt are combined, so that the 1 st arm side plate and the 2 nd arm side plate are combined to enable the centers of the 1 st through hole and the 2 nd through hole to be relatively rotated as a rotation axis. That is, the arm member 125 can be switched between a1 st state (see the two-dot chain line of fig. 13) in which the longitudinal direction of the 1 st arm 1251 coincides with the longitudinal direction of the 2 nd arm 1252, and a 2 nd state (see the solid line of fig. 13) in which the longitudinal direction of the 1 st arm 1251 intersects with the longitudinal direction of the 2 nd arm 1252. The rotation direction of the 2 nd arm 1252 of the arm member 125 with respect to the 1 st arm 1251 is a direction in which the protruding direction of the pair of protruding portions 1212 (the protruding direction of the pair of terminal plates 1211) of the connecting member 121 is the rotation axis. That is, the arm member 125 constitutes a vertical rotation mechanism that holds the unit-side cable 131 so as to be rotatable between an attitude along the vertical direction (see the two-dot chain line in fig. 13) and an attitude along the horizontal direction (see the solid line in fig. 13).
The 1 st spring 1254 and the 2 nd spring 1255 are coil springs (tension coil springs), respectively. The 1 st spring 1254 and the 2 nd spring 1255 are respectively a1 st engaging part having one end engaged with the 1 st arm side plate and a 2 nd engaging part having the other end engaged with the 2 nd arm side plate. The natural length of the 1 st and 2 nd springs 1254 and 1255 is the same as the interval between the 1 st and 2 nd catching portions when the arm member 125 is in the 2 nd state.
When the arm member 125 transitions from the 2 nd state to the 1 st state, the interval between the 1 st catch portion and the 2 nd catch portion is expanded, and the 1 st spring 1254 and the 2 nd spring 1255 are extended. The 1 st spring 1254 and the 2 nd spring 1255 decelerate a transition speed of the arm member 125 from the 2 nd state to the 1 st state by a restoring force generated by the expansion. That is, in the present embodiment, the 1 st spring 1254 and the 2 nd spring 1255 constitute a speed reduction mechanism. The speed reduction mechanism described here is a mechanism that reduces the rotational speed of the 1 st unit-side cable 13 when the 1 st unit 10 is rotated from the posture in the horizontal direction to the posture in the vertical direction by the vertical rotation mechanism (arm member 125).
The holding body 9 is a member for holding the 1 st unit 10 in a posture along the wiring duct 80. The holding body 9 is attached to, for example, the wiring duct 80.
As shown in fig. 13, the holding body 9 includes a holding body main body 90, a pair of mounting plates 91 (only 1 is shown in fig. 13), and a hook 92.
The holder main body 90 is formed in a rectangular parallelepiped shape from a resin material, and has a disc-shaped top plate on one surface side (upper surface side). A columnar portion protruding upward is provided on the upper surface of the top plate of the holder body 90. The pair of mounting plates 91 are each formed of a resin material in a plate shape. The pair of mounting plates 91 project in opposite directions from each other from the top end of the columnar portion at a distance from the top plate and in parallel with the top plate. The hook 92 is provided on the bottom surface (the surface opposite to the top panel side) of the holder main body 90.
The hook 92 is formed to have a size to which the unit 1 st cable 13 is hooked. That is, the holding body 9 includes a hook 92 to which a part of the unit 1 side cable 13 is hooked. The holding body 9 can hold the outer shell 130 of the 1 st unit-side cable 13 at a position separated from the attachment portion 12.
In the present modification, when the functional unit 22 is not used (when the input unit 21 is not connected to the connection unit 11), the 1 st unit 10 can be held in a posture along the wiring duct 80 by the holding body 9. This can further reduce the possibility that the suspension type electric appliance 100 restricts the range of motion of the person when the function unit 22 (No. 2 unit 20) is not used.
(3.8) the 8 th modification
A suspension-type electric appliance 100 according to a modification example 8 will be described with reference to fig. 14. The suspension-type electric appliance 100 of the present modification is different from the suspension-type electric appliance 100 of the basic example mainly in that the structure of the connection portion 11 is different and the holding body 9 is further included. The basic structure of the holder 9 of the present modification is the same as that of the holder 9 of the 7 th modification, but is different from that of the 7 th modification in that a 4 th engaging part 93 (magnet) is provided instead of the hook 92.
In the suspended electrical appliance 100 of the present modification example, a magnetic body as the 3 rd coupling portion 116 formed of a ferromagnetic material is accommodated in the housing 111 of the connection portion 11. In addition, a magnet as the 4 th coupling part 93 which is coupled to the 3 rd coupling part 116 by a magnetic force is housed in the holder main body 90 of the holder 9. The 3 rd joint part 116 and the 4 th joint part 93 are joined to each other by magnetic force, thereby holding the connection part 11 to the holding body 9.
Similarly to the suspended electrical appliance 100 of the 7 th modification, in the suspended electrical appliance 100 of the present modification, the 1 st unit 10 can be held in a posture along the wiring duct 80 by the holding body 9 when the functional unit 22 is not used (when the input unit 21 is not connected to the connection unit 11). This can further reduce the possibility that the suspended electrical appliance 100 restricts the range of motion of the person when the No. 2 unit 20 is not used.
In the present modification, the 3 rd coupling part may be a magnet and the 4 th coupling part may be a magnetic body, or both the 3 rd coupling part and the 4 th coupling part may be magnets. The 1 st coupling portion 110 and the 3 rd coupling portion 116 housed in the housing 111 of the connection portion 11 can be used by 1 magnet or 1 magnetic body.
(3.9) 9 th modification
The suspension-type electric appliance 100 of the present modification differs from the suspension-type electric appliance 100 of the basic example in that the 2 nd unit 20 is selected from the plurality of 2 nd units 20 having different functions. That is, the suspension-type electric appliance 100 of the present modification can be replaced with another 2 nd unit 20 (20A to 20C: see fig. 15 to 17) having a functional unit 22 different from the socket main body 220.
The 2 nd unit 20A to the 2 nd unit 20C include an input unit 21, a function unit 22, and a 2 nd unit-side cable 23, as in the 2 nd unit 20 of the basic example. The input unit 21 of the 2 nd unit 20A to the 2 nd unit 20C has the same structure as the input unit 21 of the 2 nd unit 20 of the basic example. The functional units 22 (22A to 22C) of the 2 nd unit 20A to the 2 nd unit 20C realize functions different from those of the outlet main body 220 using the electric power received from the 1 st unit 10 via the input unit 21.
As shown in fig. 15, the 2 nd unit 20A includes a lighting fixture including a light source, a lighting device, and a globe 221A as the functional unit 22A. The lighting device converts the ac power supplied from the 2 nd unit-side cable 23 into dc power suitable for the voltage of the light source. The light source is turned on by the DC power supplied from the lighting device.
As shown in fig. 16, the 2 nd unit 20B includes a speaker as the functional unit 22B. The audio signal input functional unit 22B is superimposed on the Power Line of the 2 nd unit-side cable 23 by, for example, the PLC (Power Line Communication) technology such as HD-PLC (registered trademark). The function unit 22B converts an input audio signal into sound, and outputs the sound to the outside through the casing 221B in which the mesh-like through holes are formed.
As shown in fig. 17, the 2 nd unit 20C includes a socket of a magnet socket as the functional portion 22C. The function unit 22C includes a housing 221C, a contact 222C provided in the housing 221C, and a magnetic body provided in the housing 221C. The plug of the magnet socket can be connected to the functional portion 22C.
In the present modification, the 2 nd unit 20 can be replaced with another 2 nd unit 20 (20A to 20C) having a different function. This improves usability of the suspended electrical appliance 100.
In the present modification, the functional unit 22 of the 2 nd unit 20 is not limited to the above-described socket of the lighting fixture, speaker, and magnet socket, and may be configured to realize a predetermined function using power received via the input unit 21, such as an electric fan. The functional unit 22 may be configured to realize a plurality of functions (for example, both the function of the socket and the function of the lighting fixture).
(3.10) other modifications
The 1 st unit 10 and the 2 nd unit 20 may not include the 1 st coupling part 110 (magnet) and the 2 nd coupling part 210 (magnetic body).
