Definitions

  • the present invention relates to a plug-pin receiving member gripping a plug pin, and a receptacle having the same.
  • a wall-embedded receptacle attached to a mounting frame fixed in a switch box which is installed on a back side of a wall, and connected to an electrical wire wired from the back side of the wall (e.g., Japanese Unexamined Patent Application Publication No. 2006-179308) .
  • Such a conventional receptacle includes a terminal plate 200 including: a wire connection part 210 connected to an electrical wire; and a plug-pin receiver 220 constituted by a pair of gripping pieces 221 as shown in Fig. 17A.
  • the gripping pieces 221 are disposed forwardly of the wire connection part 210.
  • the gripping pieces 221 are opposed to each other in the left-right direction Y and extend along the up-down direction Z.
  • the plug-pin receivers 220 grip the plug pin 230 to hold the plug pin 230 in the terminal plate 200, So that electrical power is supplied to the plug through the electrical wire.
  • the plug-pin receiver 220 should be formed to have a longitudinal length (in the up-down direction Z) larger than an outer diameter of the plug pin 230. This makes it difficult to miniaturize the receptacle in the up-down direction Z.
  • the longitudinal length of the plug-pin receiver 220 is shortened for the purpose of miniaturizing the receptacle in the up-down direction Z as shown in Fig. 17C, an electrical resistance of the plug-pin receiver 220 is increased. Accordingly, this causes the terminal plate 200 to heat up, which increases the heat generation in the receptacle disadvantageously .
  • an object of the present invention is to provide a plug-pin receiving member capable of suppressing an increase in electrical resistance as well as an enlargement in size, and a receptacle having the same.
  • a plug-pin receiving member to which a plug pin of a plug is to be connected includes a plug-pin receiver for gripping the plug pin that has a cylindrical part extending along an insertion direction of the plug pin. Further, the plug-pin receiver is provided with: a plug-pin holding part formed to have a minimum inner diameter of the cylindrical part; and a tip end part extended from the plug-pin holding part along the plug-pin insertion direction, the tip end part having a gradually increased inner diameter. Furthermore, the plug- pin holding part makes contact with the plug pin to hold the plug pin in the state where the plug pin is inserted into the plug-pin receiver.
  • the plug- pin receiver since the plug- pin receiver has the cylindrical part extending along the plug-pin insertion direction, it is possible to make the plug-pin receiver smaller in size than a conventional plug- pin receiver which has a terminal plate constituted by a pair of gripping pieces as shown in Figs. 17A and 17B. Accordingly, this promotes the miniaturization of the receptacle. Besides, since the plug-pin receiver is formed into a cylindrical shape, there is no need to reduce a surface area of the plug-pin receiver even if the plug-pin receiver is miniaturized. Consequently, the terminal plate is avoided from increasing its electrical resistance.
  • the tip end part is provided in the plug-pin receiver, so that other members except for the tip end part in the receptacle are less affected by an arc generated between the plug-pin receiver and the plug pin as compared with a plug-pin receiver with no tip end part.
  • the tip end part of the plug-pin receiver may be configured to have a higher melting point than that of portions other than the tip end part.
  • the tip end part of the plug-pin receiver When an arc occurs, the tip end part of the plug-pin receiver receives the arc so that temperature of the tip end part rises up higher than that of the other portions in the plug-pin receiver. Therefore, the tip end part is likely to be molten by the arc as compared with the other portions .
  • the tip end part of the plug-pin receiver is formed to have a higher melting point than that of the other portions in the plug-pin receiver. Accordingly, the melting of the tip end part by the arc can be suppressed.
  • the plug-pin receiver may be configured to have a plurality of gripping pieces formed by slits extending along the plug-pin insertion direction.
  • the slits provided in the plug-pin receiver form the plurality of gripping pieces. Therefore, the plug-pin receiver is easier to deform elastically than a plug-pin receiver with no slits. Therefore, elasticity of the plug-pin receiver is ensured.
  • a receptacle including: the plug-pin receiving member described above; a terminal plate electrically connected to the plug-pin receiving member; and a lock spring for pressing an electrical wire against the terminal plate .
  • the terminal plate and the lock spring can fasten the electrical wire by utilizing elasticity of the lock spring, thereby enabling to connect the electrical wire, through which electric power is supplied, to the terminal plate with ease.
  • the receptacle is provided with the plug-pin receiving member capable of being miniaturized as compared with the conventional plug-pin receiving member as shown in Figs. 17A and 17B, the receptacle can be miniaturized.
  • the receptacle may include: a peripheral wall insertion groove formed into a substantially quadrangular shape when viewed from the plug-pin insertion direction, a peripheral wall of the plug surrounding the plug pin being adapted to be inserted into the peripheral wall insertion groove; and a plug receiving part surrounded by the peripheral wall insertion groove and formed into a substantially quadrangular shape when viewed from the plug- pin insertion direction.
  • the plug receiving part is provided with a plurality of plug-pin insertion holes disposed along a reference side that is one side of an outer periphery of the plug receiving part, each of the plug-pin insertion holes having a circular shape.
  • the plug-pin insertion holes are disposed closer to the reference side than to an opposite side of the outer periphery of the plug receiving part in a direction perpendicular to the reference side.
  • the plug-pin insertion holes are disposed closer to the reference side than to the opposite side of the outer periphery of the plug receiving part in the direction perpendicular to the reference side, the plug is prevented from being reversely inserted into the receptacle without providing a dedicated structure for preventing the reverse insertion to the peripheral wall insertion groove and the peripheral wall of the plug.
  • an enlargement of the receptacle can be avoided as compared with the case where the dedicated structure for preventing the reverse insertion is provided in the receptacle .

Therefore, the plug-pin receiver 32 can be miniaturized in the up-down direction Z as compared with the conventional plug-pin receiver 220 shown in Figs. 17A and 17B. As a result, the miniaturization of the receptacle 10 in the up-down direction Z can be realized Further, it is possible to enlarge a surface area of the plug-pin receiver 32 as compared with the conventional plug- pin receiver 220 miniaturized in the up-down direction Z shown in Fig. 17C. Consequently, this embodiment can suppress an increase in the electric resistance of the plug- pin receiver 32 as compared with the conventional plug-pin receiver 220 shown in the above Fig. 17C.
  • plug-pin receiving member 30 of the present embodiment is formed to have the cylindrical plug-pin receiver 32. Therefore, the plug pin 44 can be in contact with the plug- pin receiver 32 over its circumference, thereby enabling the plug-pin receiver 32 to hold the plug pin 44 stably.
  • the receptacle 10 is configured to have the single module dimensions and the peripheral wall insertion groove 14 is formed in the cover 12. Therefore, a pair of plug-pin receivers 32 needs to be accommodated within an area surrounded by the peripheral wall insertion groove 14.
  • the conventional plug-pin receiver 220 is formed to have a larger volume in the up-down direction Z, it is difficult to accommodate the plug-pin receiver 220 within the area surrounded by the peripheral wall insertion groove 14.
  • the receptacle 10 of the present embodiment is miniaturized in the up-down direction Z because the plug-pin receiver 32 has a cylindrical shape. Therefore, the plug-pin receiver 32 can be accommodated within the area surrounded by the peripheral wall insertion groove 14.

  • the plug-pin insertion holes 16 are provided above the center line LI of the plug receiving part 15. Therefore, in the case where such configuration is employed in the conventional plug-pin receiver 220 shown in Fig. 17A, only an upper end portion of the plug-pin receiver 220 can be overlapped with the plug-pin insertion hole 16 because the plug-pin receiver 220 is needed to be accommodated within the area surrounded by the peripheral wall insertion groove 14. Accordingly, the plug pin 230 will be held by only the upper end portion of the plug-pin receiver 220. Consequently, the conventional plug-pin receiver 220 is unable to hold the plug pin 230 stably.
  • the receptacle 10 of the present embodiment is formed to have the plug-pin receiver 32 with a cylindrical shape extending in the front-rear direction X at the corresponding position of the plug-pin insertion hole 16. Accordingly, the plug-pin receiver 32 is able to hold the plug pins 44 stably.
  • the plug-pin receiver 32 is formed by bending. Accordingly, the elasticity of the plug-pin receiver 32 is ensured as compared with a plug-pin receiver fabricated by cutting. Further, the plug-pin receiver 32 can be manufactured easily as compared with a plug-pin receiver fabricated by drawing.
  • the plug-pin receiver 32 is provided with the slits 33. This gives a higher elasticity to the plug-pin receiver 32 as compared with a plug-pin receiver with no slits 33. As a result, the plug-pin receiver 32 can hold the plug pin 44 stably. Further, the plug-pin receiver 32 comes into contact with the plug pin 44 at more points as compared with the conventional plug-pin receiver 220 shown in Fig. 17B. Accordingly, an electric contact between the plug-pin receiver 32 and the plug pin 44 is secured.
  • the arc receiving part 34b is provided in the plug-pin receiver 32.
  • the arc is sustained for a longer time compared with an AC receptacle. Therefore, the members such as the plug-pin receiver 32 and the cover 12 are likely to be affected by the arc. Since the arc receiving part 34b receives the arc, however, the influence to the other members can be reduced. Consequently, the present embodiment is suitable for a DC receptacle.
  • the arc receiving part 34b is formed to have a higher melting point than that of the other parts of the plug-pin receiver 32. Accordingly, the arc receiving part 34b is prevented from melting due to the arc.
  • the peripheral wall insertion groove 14 is configured to have a substantially quadrangular shape whose two lower corners are cut away. Therefore, this restricts an orientation of inserting the peripheral wall 45 of the plug 40 as compared with the receptacle 100 whose peripheral wall insertion groove 111 is annular as shown in Figs. 16A and 16B, based on IEC standards. Accordingly, since a user is easily aware of the insertion orientation of the plug 40 into the receptacle 10, its operability is improved. Consequently, the user can easily insert the plug 40 into the receptacle 10 while suppressing the reverse insertion.
  • the plug-pin insertion hole 16 is disposed above the center line LI of an outer periphery of the plug receiving part 15. Accordingly, the reverse insertion of the plug 40 into the receptacle 10 can be suppressed without providing a dedicated structure for preventing the reverse insertion in the peripheral wall insertion groove 14 and the peripheral wall 45. As a result, the enlargement of the receptacle 10 can be suppressed as compared with a receptacle having the dedicated structure for preventing the reverse insertion.
  • the peripheral wall insertion groove 111 has an annular shape as shown in Fig. 16B, the following problem will be caused. That is, when the plug-pin insertion holes 112 are disposed on the upper half side in the circle, the distance between the plug-pin insertion holes 112 is reduced to decrease their dielectric strength. Further, it is supposed that the peripheral wall insertion groove 111 has a quadrangular shape and the plug-pin insertion hole has a rectangular shape whose longer side extends in the up-down direction Z as shown in Fig. 16C. When the plug-pin insertion holes 112 are disposed on the upper half side in the quadrangle as shown in Fig. 16D, it is required to enlarge an outer shape of the receptacle 100.
  • the plug- pin insertion hole 16 is formed to have a circular shape while the peripheral wall insertion groove 14 is formed to have a quadrangular shape. Therefore, even if the plug-pin insertion holes 16 are disposed above the center line LI, it is prevented that the distance between the plug-pin insertion holes 16 is reduced. Consequently, this improves their dielectric strength as compared with the receptacle 100 shown in Fig. 16D. Further, unlike the receptacle 100 in Fig. 16D, there is no need to enlarge its outer shape, and the receptacle 10 can have the single module dimensions.
  • the receptacle 10 is formed to have a size of the single module dimensions based on Japanese Industrial Standards, in which three receptacles with the single module dimensions can be accommodated in a mounting frame of a large rectangular string wiring accessory. Therefore, the receptacle 10 can be attached to a mounting frame of the other wiring accessories standardized by the same standards. Accordingly, there is no necessary to manufacture a dedicated mounting frame for the receptacle 10 independently, and the mounting frame can be used commonly. Consequently, the receptacle 10 can be attached to the mounting frame together with the other wiring accessories having the single module dimensions or the two-piece module dimensions, thereby improving its operability .
  • the front surface 15e of the plug receiving part 15 and the front surface 12a of the cover 12 are formed flush with each other in the front-rear direction X.
  • the plug pins 44 are configured to be located slightly forward of the rear end portion of the peripheral wall 45. According to such configurations, when the plug 40 is reversely inserted into the receptacle 10, the plug pins 44 come into contact with the plug receiving part 15 before the peripheral wall 45 is excessively inserted into the peripheral wall insertion groove 14. Accordingly, a user is aware of the reverse insertion more clearly, and additionally, the plug 40 is avoided from remaining in the receptacle 10 when being inserted reversely. Accordingly, the state of the reverse insertion is prevented from being maintained.
  • the ends 35 of the cylindrical body 32a are configured to be separated from each other. Therefore, the elasticity of the two gripping pieces 34 which have the ends 35 can be increased as compared with that of a cylindrical body of which the ends 35 are connected to each other. As a result, the elasticity of the plug-pin receiver 32 can be ensured.
