[0025] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0028] As Figure 1 shown, the riveting part of the first embodiment includes: a riveting part 10 and a thread-passing head 20. Among them, the riveting part 10 has opposite riveting surfaces and a connecting surface; the thread-passing head 20 is arranged on the connecting surface, and a thread-passing channel 21 is arranged on the thread-passing head 20, and the axes of the two channel openings 22 of the thread-passing channel 21 are arranged at an angle.

[0029] Applying the technical solution of Application Example 1, when the riveting part is applied to the bottom of the side wall of the box body, since the axes of the two channel openings 22 of the wire threading channel 21 are arranged at an angle, therefore, compared with the wire fixing device in the background art, the distance between the channel opening 22 close to the bottom of the box body and the bottom of the box body has increased, making it very easy for the user to pull the wire out of the through hole or feed the wire into the through hole, thus improving the efficiency of wire fixing.

[0030] It should be noted that the "distance between the channel opening 22 close to the bottom of the box body and the bottom of the box body" specifically refers to the "distance between the center of the channel opening 22 close to the bottom of the box body and the bottom of the box body".

[0031] As Figure 1 shown, in the first embodiment, one of the two channel openings 22 of the wire threading channel 21 is arranged on the side wall of the wire threading head 20, and the other channel opening 22 is arranged on the end wall of the wire threading head 20 away from the riveting part 10. The above structure makes the channel opening 22 no longer face the bottom of the box body, but face the inside of the box body. In this way, even if the riveting part is very close to the bottom of the box body (that is, the gap between the riveting part and the bottom of the box body is smaller than the diameter of the wire), it does not affect the penetration or extraction of the wire. On the one hand, it improves the efficiency of installing the electronic device into the box body, and on the other hand, it enables the riveting part to be closer to the bottom wall of the box body, improving the flexibility of wire arrangement.

[0032] As Figure 1 shown, in the first embodiment, the wire threading head 20 is columnar. The side wall of the wire threading head 20 includes a first machining plane 23, and the surface of the end wall of the wire threading head 20 is an end plane 24. One of the two channel openings 22 of the wire threading channel 21 is arranged on the first machining plane 23, and the other channel opening 22 is arranged on the end plane 24. Specifically, the setting of the machining plane makes the channel opening 22 easier to machine. In addition, since the wire threading head 20 itself is columnar and its end face is a plane, there is no need to machine the end face during machining, improving production efficiency.

[0033] As Figure 1 shown, in the first embodiment, a first blind hole is arranged at the first machining plane 23 of the wire threading head 20, and a second blind hole communicating with the first blind hole is arranged at the end plane 24 of the wire threading head 20. The channels in the first blind hole and the second blind hole form the wire threading channel 21. The above structure is simple and easy to machine.

[0034] As Figure 1As shown, in the first embodiment, the riveting portion 10 is a stepped structure, and a pressing groove 11 is formed between the stepped surface of the riveting portion 10 and the wire threading head 20. Specifically, the riveting portion 10 actually includes a riveting section with a larger diameter and a connecting section with a smaller diameter. Among them, the end surface of the riveting section forms a riveting surface, and the end surface of the connecting section forms a connecting surface. During riveting, a part of the riveting section will be pressed into the pressing groove 11, so that the riveting portion 10 is arranged in the hole of the box body in an interference fit manner to complete the riveting fixation.

[0035] As Figure 1 shown, in the first embodiment, the riveting portion 10 and the wire threading head 20 are of an integral structure. The above structure is simple, low in cost, and high in reliability.

[0036] The difference between the second embodiment and the first embodiment lies in the shape of the wire threading channel 21. Specifically, in the second embodiment, an L-shaped bent hole is provided on the wire threading head 20, and the channel in the L-shaped bent hole forms the wire threading channel 21. Specifically, the L-shaped bent hole specifically includes a vertical hole section, a horizontal hole section, and a guiding bent hole connecting the vertical hole section and the horizontal hole section. The above structure enables the L-shaped bent hole to play a guiding role for the cable when the user threads the cable, making it easier for the cable to pass through, thereby further improving the efficiency of fixing the cable.

[0037] The difference between the third embodiment and the first embodiment lies only in the setting position of the channel opening 22. Specifically, in the third embodiment, the side wall of the wire threading head 20 includes a second machining plane and a third machining plane, and an angle is formed between the normal line of the second machining plane and the normal line of the third machining plane. The two channel openings 22 of the wire threading channel 21 are respectively arranged on the second machining plane and the third machining plane. The above structure enables the channel opening 22 not to face the bottom of the box body, but to face the side of the box body. In this way, even if the riveting part is very close to the bottom of the box body (that is, the gap between the riveting part and the bottom of the box body is smaller than the diameter of the cable), it does not affect the penetration or passing through of the cable. On the one hand, the efficiency of installing the electronic device into the box body is improved, and on the other hand, the riveting part can be closer to the bottom wall of the box body, improving the flexibility of cable layout.

[0038] The present application also provides a wiring box, as Figure 2 shown, the wiring box according to this embodiment includes: a box body 30 and a riveting part 40. Among them, the riveting part 40 is the above-mentioned riveting part, the riveting portion 10 of the riveting part 40 is riveted on the box wall of the box body 30, and the wire threading head 20 of the riveting part 40 is located inside the box body 30. Since the above-mentioned riveting part has the advantage of improving the cable fixing efficiency, the wiring box having it also has the above advantages. Preferably, in this embodiment, the wiring box is a box body for installing an inverter.

[0039] As Figure 2As shown, in this embodiment, the riveting part 10 is riveted to the bottom of the side wall 31 of the box body 30, and one of the two channel openings 22 of the wire threading channel 21 is arranged on the upper surface of the wire threading head 20. On the one hand, the above structure improves the efficiency of installing the electronic device into the box body, and on the other hand, it enables the riveting part to be closer to the bottom wall of the box body, improving the flexibility of cable layout.

[0040] The present application also provides an inverter. The inverter according to this embodiment includes: a junction box, and the junction box is the above-mentioned junction box. Since the above-mentioned junction box has the advantage of improving the cable fixing efficiency, the production efficiency of the inverter with it is high.

Thus, the exemplary term "above..." can include both orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0043] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0044] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
