[0039] The embodiment of the present invention discloses a wiring structure for connecting an internal element of an electrical enclosure (1) with an external cable (2), and the wiring structure includes a first mounting member (3) and a second mounting member (4).

When the conductive connecting parts 5 and the conductive engaging parts 6 are engaged and connected, the conductive connecting parts 5 and the conductive engaging parts 6 may be directly connected and conductive, or indirectly connected and conductive, or may be engaged and conductive in a corresponding manner. In this manner, the number of conductive connecting parts 5 is the same as the number of conductive engaging parts 6, and multiple conductive engaging parts 6 may be engaged with one conductive connecting part 5 and conductive, or multiple conductive connecting parts 5 may be engaged with one conductive engaging part 6 and conductive; that is, the number of conductive connecting parts 5 is different from the number of conductive engaging parts 6, and the conductive connecting parts 5 and the conductive engaging parts 6 may be arranged in a matrix, or in a circular, multi-layer, radial, or staggered array in multiple rows.

[0041] As can be seen from this, compared to the prior art, the wiring structure provided by the embodiments of the present invention has a plurality of conductive connecting parts 5 integrated into the first mounting member 3 and a plurality of conductive engaging parts 6 integrated into the second mounting member 4, with each conductive engaging part 6 connected to a single cable. In this way, the butt-connection structure of the first mounting member 3 and the second mounting member 4 enables a fixed connection between the plurality of cables and the electrical housing 1. There is no need to place an insulating sleeve on the end of each external cable 2, resulting in a smaller volume and a more compact structure, which reduces the spatial requirements of the cable connection structure of the electrical housing 1 and contributes to the miniaturization of the electrical housing 1. Multiple external cables 2 can be simultaneously attached to the electrical housing 1, improving the efficiency of insertion of the external cables 2. Furthermore, using this structure for simultaneously inserting multiple external cables 2, the arrangement of the conductive connecting parts 5 and the conductive engaging parts 6 provides a foolproof effect and prevents errors. Furthermore, each conductive engaging part 6 can slide relative to the second mounting member 4 according to the external cables 2, allowing each conductive engaging part 6 to be inserted and removed individually, making the operation more flexible.

[0042] In one embodiment of the present invention, the conductive connection parts 5 and the conductive engaging parts 6 are directly engaged and connected to each other for electrical conduction. As shown in FIG. 5, in this embodiment, one of the conductive connection parts 5 and the conductive engaging parts 6 is provided with a connection pin, and the other is provided with a pinhole. The connection pin is inserted into the pinhole for connection, thereby engaging and conducting the conductive connection parts 5 and the conductive engaging parts 6. That is, one of the conductive connection parts 5 and the conductive engaging parts 6 may be provided with a pin-like structure only at the end, and the other may be provided with a hole-like structure only at the end, or one of the conductive connection parts 5 and the conductive engaging parts 6 may be provided with a pin-like structure as a whole. 5, the conductive connecting part 5 and the conductive engaging part 6 may be connected and engaged in a one-to-one plugging-in manner, or in a many-to-one plugging-in manner, i.e., one of the conductive connecting part 5 and the conductive engaging part 6 may be provided with a plurality of engaging ends, which converge to a connecting end for connecting to an external cable 2 or an internal element of the housing.

When mounting, first, the adapter structure and each conductive engaging part 6 are inserted and engaged to fix, and then the second mounting part 4 having the adapter member and each conductive connection part 5 on the first mounting part 3 are engaged and mounted. In this mounting structure, the conductive engaging parts 6 are fixed relatively to the second mounting part 4 by the external cable 2, which prevents the conductive engaging parts 6 from being unfixed in position, and makes it easy to align the conductive connection parts 5 on the first mounting part 3 with the corresponding conductive engaging parts 6 on the second mounting part 4.

[0044] A variety of structures may be adopted for the adapter member.

As shown in FIG. 11, one adapter output end of an adapter member is connected to multiple adapter input ends correspondingly. In the illustrated embodiment, one adapter output end of a conductive adapter part 9' is connected to two adapter input ends, so that the conductive adapter part 9' has a Y-shaped structure. Of course, the Y-shaped conductive adapter part 9' is only a preferred implementation solution provided by the embodiment of the present invention. In practice, one adapter output end may be connected to three, four or more adapter input ends correspondingly, or a solution in which multiple adapter output ends are connected to one adapter input end may be adopted according to needs, and this is not limited thereto.

[0050] Preferably, the wiring structure further includes an overload protection device, which includes, but is not limited to, a fuse 15.

[0056] Preferably, as shown in FIG. 6, in this embodiment of the present invention, the first mounting element 3 includes a base having a groove surrounded by an annular protrusion, and the conductive connecting parts 5 are disposed in the groove. The second mounting element 4 includes a housing that is removably and sealingly engaged with and connected to the base, covering the annular protrusion.

[0057] Furthermore, to improve the sealing performance between the first mounting member 3 and the second mounting member 4, a sealing structure may be provided between the end face of the open end of the housing and the base as shown in FIG. 14, and / or a sealing structure may be provided between the inner wall of the housing and the outer wall of the annular convex base as shown in FIGS. 8 and 10, the sealing structure including at least one sealing ring 10, which may be an O-ring, a lip-shaped sealing ring, or the like, or may be a labyrinth sealing structure or a combination of a labyrinth sealing structure and a sealing ring 10.

[0058] Preferably, as shown in FIG. 6, a sealing structure is provided on the surface of the base that comes into contact with the electrical housing 1, and the sealing structure includes at least one sealing ring 11, which may be an O-ring, a lip-shaped sealing ring, or the like, to achieve sealing between the base and the housing.

[0059] The connection method between the first mounting member 3 and the second mounting member 4 will now be described in detail, and the first mounting member 3 and the second mounting member 4 are removably connected by a buckle structure and / or screw fastening parts.

[0060] In one embodiment, the buckle structure between the first mounting member 3 and the second mounting member 4 includes elastic hooks 13 and hook grooves 14, and the multiple elastic hooks 13 are uniformly arranged along the circumferential direction on one of the first mounting member 3 and the second mounting member 4, and the multiple hook grooves 14 and each elastic hook 13 are arranged correspondingly on the other of the first mounting member 3 and the second mounting member 4, and the elastic hooks 13 and the hook grooves 14 are engaged with each other to removably connect the first mounting member 3 and the second mounting member 4.

[0061] As shown in Figure 10, the elastic hooks 13 are provided on the first mounting member 3, and the hook grooves 14 are provided on the second mounting member 4. When the first mounting member 3 and the second mounting member 4 approach each other until the second mounting member 4 comes into contact with the elastic hooks 13, the elastic hooks 13 are elastically deformed by the action of the inner walls of the hook grooves 14 of the second mounting member 4 and brought together (of course, they may be dispersed depending on the installation orientation of the elastic hooks 13). When the first mounting member 3 and the second mounting member 4 are fully engaged, the hook-shaped end structures of the elastic hooks 13 extend out of the hook grooves 14, and the inner walls of the hook grooves 14 no longer press against the elastic hooks 13 to elastically deform them. Instead, the elastic hooks 13 return to their original position by their own elasticity and engage with the end face of the hook grooves 14 away from the first mounting member 3, thereby realizing the engagement between the first mounting member 3 and the second mounting member 4.

[0062] Of course, the buckle structure is not limited to the above structure.

Here, the engagement occurs when the lock hook 17 catches the lock pin 18 and connects the first mounting member 3 and the second mounting member 4. This refers to a detachable connection. In the embodiment of FIG. 15, a locking hook 17 is provided on the second mounting member 4, and a locking pin 18 is provided on the first mounting member 3. The second mounting member 4 may have one locking hook 17 or multiple locking hooks 17 arranged symmetrically, with the number and position of the locking hooks 17 corresponding to the number and position of the locking hooks. To attach the locking hooks, the user first rotates the locking hook 17 so that its opening faces the first mounting member 3, and then attaches the second mounting member 4 to the first mounting member 3.
