Detailed Description

In the related art, an electric control board is disposed in an electric control box of an air conditioner outdoor unit, and the electric control board is generally electrically connected to an external power source through a wire holder disposed in the electric control box. In the case where a plurality of external connection terminals are connected to one connection terminal at the same time as this, interference and mutual influence are liable to occur between the respective external connection terminals to be electrically connected together, resulting in low connection reliability between the external connection terminals and the connection terminals.

In view of this, in the embodiments of the present invention, the terminal surfaces located at different heights are disposed in the terminal block, and the conductor terminals corresponding to the terminal surfaces located at different heights are electrically connected, so that the external connection terminals disposed on the terminal surfaces located at different heights are staggered in the height direction of the base, and therefore, the external connection terminals do not affect or interfere with each other, and the connection reliability is high.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is an exploded view of a wire holder 100 according to an embodiment of the present invention, fig. 2 is a partially enlarged view of a portion a of fig. 1, and fig. 3 is a top view of the wire holder 100. Referring to fig. 1, 2, and 3, the wire holder 100 includes: a base 110, and at least two wiring members 130 disposed on the base 110. The base 110 is a component for carrying the wiring assembly 130 and the external wiring terminal 104, and the base 110 may be connected to the electronic control box 200 by a fastener or the like. And the wiring assembly 130 is used to electrically connect the internal electrical unit of the electrical control box 200 with the corresponding external wiring terminals 104 of the external electrical unit.

It should be noted that, in the drawings of the present invention, for convenience of description, the longitudinal direction of the wire holder 100 is defined as a first direction F. The base 110 may be divided into an external connection side W and an internal connection side N, which are disposed opposite to each other in the width direction H of the wire holder 100, wherein the external connection side W corresponds to a side of the wire holder 100 connected to a connection source outside the electrical control box 200, and the internal connection side corresponds to a side of the wire holder 100 connected to each electrical component inside the electrical control box 200.

With continued reference to fig. 1, the base 110 has a plurality of supporting units 120, the supporting units 120 are members formed on the base 110 for supporting the wiring members 130, in order to better support the wiring members 130, it is necessary to provide the supporting units 120 and the wiring members 130 in one-to-one correspondence, and in fig. 3, the plurality of supporting units 120 are arranged side by side in the first direction F of the base 110, and correspondingly, the plurality of wiring members 130 are also arranged side by side in the first direction F of the base 110, which makes the layout of the connector holder more compact.

Referring to fig. 1 and 2, each supporting unit 120 includes a plurality of terminal surfaces 123, and the connection assembly 130 has a plurality of conductor terminals 131 disposed corresponding to the terminal surfaces 123, which means that for each supporting unit 120 and the connection assembly 130 corresponding to the supporting unit 120, the terminal surfaces 123 included in the supporting unit 120 and the conductor terminals 131 included in the connection assembly 130 are in a one-to-one correspondence relationship, that is, one conductor terminal 131 is disposed on one terminal surface 123.

And the terminal face 123 is configured to support the external connection terminal 104 electrically connected to the conductor terminal 131, which means that the conductor terminal 131 on the terminal face 123 is used to electrically connect to the external connection terminal 104, and the terminal face 123 can support the external connection terminal 104 to which the conductor terminal 131 is connected. Thus, the height of the terminal face 123 determines the height of the external connection terminal 104. It will be appreciated that such support may be indirect or direct, including the external terminals being supported on the respective terminal faces by metal pads or conductor terminals or the like. Direct support includes the external terminals being supported in direct contact with the corresponding terminal faces.

It should be noted that the conductor terminals 131 in the same wiring assembly 130 need to be electrically connected to each other, so that the different external connection terminals 104 on the external connection side W and the internal connection side N to which the conductor terminals 131 are connected can be electrically connected.

Illustratively, the wire connection assembly 130 may further include a conductive sheet 132, and the conductive sheet 132 is a sheet that may be formed by stamping the entire sheet. The conductor terminals 131 included in the same wiring member 130 may be connected by the same conductive sheet 132, for example, the width of the conductive sheet 132 may be larger than the width of the conductor terminal 131, so that the conductor terminal 131 is disposed at a position substantially in the middle of the width direction of the conductive sheet 132.

The conductive sheet 132 may be supported on the corresponding plurality of terminal surfaces 123, including the above-mentioned indirect support and direct support, and the conductive sheet 132 is directly supported on the plurality of terminal surfaces 123 as an example.

In other words, since each conductor terminal 131 is connected to the conductive sheet 132, the conductor terminal 131 and the terminal face 123 corresponding to the conductor terminal 131 can be fixed relative to each other by simply supporting the conductive sheet 132 on the terminal face 123.

In this embodiment, an example of connecting the conductor terminals 131 in the same wiring assembly 130 by the conductive sheet 132 is given, but the present invention is not limited thereto, and the conductor terminals 131 included in the same wiring assembly 130 may be connected by a conductive wire, or the conductor terminals 131 included in the same wiring assembly 130 may be electrically connected by conductors of other shapes, and the principle of electrical connection in this embodiment is similar to that of connection by the conductive sheet 132, and will not be described herein again.

Referring to fig. 1 and 2, as mentioned above, the base 110 has an inner connection side N and an outer connection side W, and the plurality of terminal surfaces 123 in each support unit 120 may include a first terminal surface 121 and at least two second terminal surfaces 122 according to different arrangement positions, the first terminal surface 121 is located on the inner connection side N of the base 110 and may be used for electrical connection with the electrical components inside the pair of electronic control boxes 200, and the second terminal surface 122 is located on the outer connection side of the base 110 and may be used for connection with a connection source outside the electronic control boxes 200, such as the external power source 206. However, the number of the first terminal surfaces 121 may be plural depending on the number of the external terminals connected to the inner connection side N.

Among the plurality of second terminal surfaces 122 in the same supporting unit 120, at least two second terminal surfaces 122 have different heights with respect to the bottom end of the base 110. As mentioned above, the conductor terminals 131 corresponding to the second terminal surfaces 122 can be used to connect the external connection terminals 104, and when the heights of the at least two second terminal surfaces 122 are different relative to the bottom end of the base 110, the heights of the external connection terminals 104 supported on the at least two second terminal surfaces 122 are also different, that is, the at least two external connection terminals 104 are arranged in a staggered manner in the height direction, so that the requirement of compact space on the external connection side W can be met, and the connection installation process can be more convenient and faster, thereby realizing dense connection in a limited space. Wherein, the height relative to the bottom end of the base 110 generally refers to the height relative to the bottom end surface of the base 110, the wire holder 100 is generally fixed on the circuit board in the electrical control box 200, and the bottom end surface of the base 110 is generally a plane surface considering that the circuit board is generally a flat surface structure.

In the embodiment of the present invention, in addition to the scheme that the installation heights of at least two second terminal surfaces 122 are different, the heights of all the second terminal surfaces 122 relative to the bottom end of the base 110 in the plurality of second terminal surfaces 122 in the same supporting unit 120 may be different, so that more external connection terminals may be connected to the external connection side W. With this arrangement, the space utilization rate in the height direction can be improved, so that the structure of the wire holder 100 is more compact.

With continued reference to fig. 1 and 3, among the second terminal surfaces 122 included in the same support unit 120, the heights of the different second terminal surfaces 122 with respect to the bottom end of the base 110 are gradually reduced from the inner connection side N to the outer connection side W. This facilitates the user's manipulation of the wire assembly 130 on the external connection side W.

In the embodiment of the present invention, referring to fig. 1 and 3, in order to make the layout of the plurality of wiring assemblies 130 neat and compact, the plurality of wiring end surfaces 123 included in the same supporting unit 120 may be sequentially arranged in the opposite direction of the inner connecting side N and the outer connecting side W. Of course, the present invention is not limited to this, and other arrangement manners are also possible, for example, the plurality of connection end surfaces 123 included in the same supporting unit 120 are still arranged in a row, and the arrangement direction has an angle with the width direction H.

In addition, referring to the sectional views of fig. 2 and 4, among at least two second terminal surfaces 122 included in the same supporting unit 120, the second terminal surface 122 adjacent to the first terminal surface 121, that is, the second terminal surface 122 adjacent to the first terminal surface 121, and the first terminal surface 121 have the same height with respect to the bottom end of the base 110. This facilitates the wiring operation of the conductive sheet 132 and also simplifies the structure of the base 110. Alternatively, the first terminal surface 121 and the second terminal surface 122 may be disposed at different heights in the same wiring member 130.

The following describes implementations of the first and second terminal surfaces 121 and 122. Referring to the cross-sectional view of fig. 4, at least two steps 111 are formed on the external connection side W of the base 110, the number of the steps 111 can be selected according to actual needs, and in the embodiment of the present invention, the number of the steps 111 is two, but the present invention is not limited thereto, and may also be three, four or more.

At least two step parts 111 may be sequentially arranged in the height direction D of the base 110, that is, at least two step parts 111 have different heights in the height direction D so that their tip end surfaces are located at different height positions, and in fact, the tip end surfaces of the step parts 111 may form the second terminal end surfaces 122, respectively. Opposite to the pair of inner connection sides N, a support pedestal 112 is formed on the base 110, and a top end face of the support pedestal 112 may form the first terminal end face 121. It is understood that the step portion 111 with the highest height among the plurality of step portions 111 and the support base 112 may be connected to each other to form a whole, or the step portion 111 with the highest height may have a space with the support base 112 for better isolation.

The present invention is explained by taking an example in which the support pedestal 112 forms one first terminal end surface 121, but the present invention is not limited to this, and a plurality of step portions arranged in order in the height direction D may be formed on the inner connection side N, and the setting heights of these step portions may be different so that the tip end surfaces of these step portions form the first terminal end surface 121. In this way, different layouts of the plurality of first terminal faces 121 in height can also be realized on the inner connection side N of the wire holder 100.

In the embodiment of the present invention, referring to fig. 1 and fig. 4, the conductive sheet 132 may be supported on the terminal end face 123, for example, a shape of a surface of the conductive sheet 132 facing the step 111 is identical to a shape of a surface formed by at least two adjacent steps 111.

The supporting structure of the wiring member 130 on the supporting unit 120 is explained in detail below.

Fig. 5 is a partial enlarged view of fig. 4 at B, and referring to fig. 4 and 5, in the embodiment of the present invention, in order to facilitate fixing the external connection terminals 104 on the corresponding terminal surfaces 123, the connection terminal assembly 130 further includes connection studs 140 corresponding to the terminal surfaces 123 one by one, and the connection studs 140 may penetrate through the external connection terminals 104 and the conductor terminals 131 to achieve electrical connection therebetween.

Of course, the present invention is not limited to this, and the external connection terminal 104 may be fixed to the corresponding terminal face 123 in other ways, for example, the external connection terminal 104 may be connected to the conductor terminal 131, and the conductor terminal 131 may be fixed to the corresponding terminal face 123, so that the external connection terminal 104 and the terminal face 123 are fixed to each other.

Illustratively, the top end surface of the support pedestal 112 is provided with a first avoiding hole 124, and after the connection stud 140 penetrates through the conductor terminal 131 and the external connection terminal 104 corresponding to the top end surface of the support pedestal 112, the connection stud can extend into the first avoiding hole 124. Similarly, a second avoiding hole 125 may be formed in the top end surface of at least one step portion 111, and the connection stud 140 may extend into the second avoiding hole 125 after penetrating through the outer connection terminal 104 and the conductor terminal 131 corresponding to the top end surface of the step portion 111. Here, the first avoiding hole 124 and the second avoiding hole 125 may be blind holes or may be through holes.

Generally, the base 110 may be made of an insulating material such as plastic, and formed by injection molding, and if the connection stud 140 is screwed to the step 111, the support base 112, or the like, the screw connection is very likely to fail when the wire holder is used many times. The conductor terminal 131 is a metal component, and a threaded hole may be formed in the conductor terminal 131, so that the connection stud 140 may be reliably connected by being threaded to the conductor terminal 131, and after the connection stud 140 penetrates through the conductor terminal 131, it may extend into the first avoiding hole 124 or the second avoiding hole 125, so that the structure of the base 110 is simpler and more compact. For example, referring to fig. 1 and 4, each conductor terminal 131 may be a convex pillar structure disposed on the back surface of the conductive sheet 132, and the convex pillar structure further has an internal threaded hole 1311 penetrating the conductive sheet 132 and the conductive terminal.

On the basis of the above scheme, referring to fig. 4 and 5, a counterbore 1251 may be further provided at the orifice position of the second avoidance hole 125, and the conductor terminal 131 corresponding to the top end surface of the step portion 111 is located within the hole section range of the counterbore 1251, so that when the connection stud 140 extends into the second avoidance hole 125, the conductor terminal 131 having a diameter slightly larger than that of the connection stud 140 may be accommodated within the hole section range of the counterbore 1251. In the present invention, the counter bore structure is provided on the step portion 111 at a lower position as an example, but the present invention is not limited thereto, and a counter bore structure may be provided on any step portion 111.

In addition, as another possible implementation manner, referring to fig. 2, the aperture edge position of the second avoidance hole 125 may further be provided with a protrusion 1252, and the conductive plate 132 may be supported at a top end of the protrusion 1252, so that the conductor terminal 131 corresponding to the second avoidance hole 125 may be naturally accommodated in the second avoidance hole 125. In the present invention, the protrusion 1252 is provided on the step portion 111 at a higher position as an example, but the present invention is not limited to this, and the protrusion 1252 may be provided on any step portion 111.

In the embodiment of the present invention, referring to fig. 2 and 6, in order to isolate the inner connection side N from the outer connection side W, it may be considered that the wire holder 100 includes a first isolation plate 150 disposed on the base 110, the first isolation plate 150 extends along the first direction F, that is, along the arrangement direction of the plurality of supporting units 120, and the first isolation plate 150 may be blocked between all the first terminal end surfaces 121 and all the second terminal end surfaces 122. This prevents the inner connection side N and the outer connection side W from interfering with each other when connected.

Further, referring to fig. 2, the conductive sheet 132 extends from the inner connection side N to the outer connection side W, and in order to facilitate the installation of the conductive sheet 132, a passage for the conductive sheet 132 to pass through may be opened on the first isolation plate 150, and the first isolation plate 150 is exemplarily provided with an opening 151 for the conductive sheet 132 and the conductor terminal 131 corresponding to the first terminal end surface 121 to pass through.

In an embodiment of the present invention, with continued reference to fig. 6, the wire holder 100 may further include at least one second isolation plate 160 disposed on the base 110, and when the number of the second isolation plates 160 is multiple, the second isolation plates 160 may be disposed parallel to each other. Also, the second partition plate 160 extends from the pair of inner connection sides N to the pair of outer connection sides W of the base 110 in the width direction H.

Among the plurality of second isolation plates 160, a part of the second isolation plates 160 are located between the wiring assemblies 130 adjacent to each other in the first direction F, and another part of the second isolation plates 160 are located outside the wiring assemblies 130 outermost in the first direction F, so that different wiring assemblies 130 can be isolated from each other to prevent short circuit. For example, the middle portions of the plurality of second isolation plates 160 in the width direction may be connected to the first isolation plate 150, so that the first isolation plate 150 and two adjacent second isolation plates 160 may jointly define a semi-open space therebetween, so that in the same wiring assembly 130, the portion on the inner connection side N and the portion on the outer connection side W may be separated by the first isolation plate 150, and the adjacent wiring assemblies 130 may also be separated by the second isolation plates 160.

In the embodiment of the present invention, referring to fig. 7, in order to pre-fix the conductive sheet 132 before the connection stud 140 is connected, the two adjacent second isolation plates 160 may further have a bump 161 on the opposite side, the bump 161 may be located on the external connection side W of the base 110, and the conductive sheet 132 is clamped between the bump 161 and the second terminal surface 122. In other words, the bump 161 has a pitch from the second terminal end surface 122 in the height direction. Each of the terminal assemblies 130 may be correspondingly provided with two bumps 161, and the two bumps 161 may be respectively located on opposite surfaces of two adjacent second separators 160.

Referring to fig. 7, it can be understood that, in order to facilitate the assembly of the conductive sheet 132 and the bump 161, it may be considered that the top end surface of the bump 161 is provided as an inclined surface, and the inclined surface is inclined toward the bottom end of the bump 161.

In an embodiment of the present invention, in order to fix the wire holder 100 in the electrical control box 200, a fixing portion 170 may be disposed at an edge of the base 110, and a waist-shaped hole 171 may be disposed on the fixing portion 170. As a possible way, a fastener may be fixed to the case body 210 of the electronic control case 200 through the waist-shaped hole 171. Illustratively, referring to fig. 3, fixing portions 170 are provided at opposite side edges of the base 110, and two kidney-shaped holes 171 are provided at the fixing portions 170 at each side edge, the kidney-shaped holes 171 being spaced apart in the width direction H. Thus, when the wire holder 100 is fixed to the circuit board in the electronic control box 200, the fastener is provided in each of the waist-shaped holes 171, and the wire holder can be fixed to the circuit board more reliably.

Referring to the schematic structural diagram of the electrical control box 200 in fig. 8, the present invention further provides an electrical control box 200, which includes a box body 210 and the wire holder 100 as described above, and the wire holder 100 can be disposed in the box body 210.

The electronic control box 200 may be, for example, a sealed electronic control box. Therefore, other foreign matters such as water drops and dust can be prevented from entering the electric control box 200 to damage electronic elements in the electric control box 200, and the waterproof, dustproof and anticorrosion effects are achieved.

The electrical control box 200 may include a box body 210 and a circuit board disposed in the box body 210, and the wire holder 100 may be disposed on the circuit board. The conductor terminal of the wire holder 100 on the inner connection side can be electrically connected to the filter unit 204, the reactor unit 205, and the like; the conductor terminal 131 of the wire holder located on the external connection side W can be electrically connected with a corresponding terminal of the external power supply. Such that the wire holder 100 can electrically connect an external power source to the various electrical units inside the electrical control box 200.

The embodiment of the present invention further provides an air conditioner 300, and the air conditioner 300 may be, for example, a central air conditioner, and the central air conditioner may include an air conditioner internal unit and an air conditioner external unit 301, where the electric control box 200 in the above embodiment is disposed in the air conditioner external unit 301.
