Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides an electric power track, which comprises a track shell 1, a wiring shell 2, a first fastening piece 3 and an E-pole conductive piece 4, wherein the track shell 1 is provided with a containing cavity 11, a strip-shaped opening 12 is formed in the track shell 1, the strip-shaped opening 12 is communicated with the containing cavity 11, and the track shell 1 comprises a conductor part 13. The junction housing 2 is located at the end of the receiving chamber 11. The first fastener 3 fixedly connects the track housing 1 and the junction housing 2, and the first fastener 3 is connected to the conductor portion 13. The E-pole conductive member 4 is at least partially located within the receiving cavity 11, and the E-pole conductive member 4 is in contact with the first fastener 3 to effect an electrical connection between the E-pole conductive member 4 and the conductor portion 13.

According to the power rail provided by the embodiment of the application, the first fastener 3 not only can realize the fixed connection between the rail housing 1 and the wiring housing 2, but also can be used as a conductive piece to realize the electric connection between the E-pole conductive piece 4 and the conductor part 13 in the rail housing 1. Compared with the mode of crimping the E-pole conductive piece and the fastening screw, the E-pole conductive piece is directly contacted with the first fastening piece 3, so that a larger contact area between the E-pole conductive piece 4 and the first fastening piece 3 is allowed to be realized, and the grounding stability of the power track can be improved.

Further, in the related art, the fixing manner of crimping the E-pole conductive member on the track housing by using the additional fastening screw, in order to improve the grounding stability, the local oxide layer of the track housing needs to be damaged, so as to increase the effective electrical contact area between the track housing and the fastening screw, and the E-pole conductive member, which further increases the processing cost of the power track. In contrast, in the power rail provided by the embodiment of the application, the contact area between the E-pole conductive piece 4 and the first fastening piece 3 is large, and the first fastening piece 3 is connected with the rail shell 1, so that the processing cost for damaging the local oxide layer of the rail shell 1 is reduced.

It will be appreciated that the track housing 1 may be made only partly of a conductor material as the conductor part 13, which conductor part 13 may be, for example, an upper cover part of the track housing 1, or the track housing 1 may be made entirely of a conductor material, so that the entire track housing 1 may be used as the conductor part 13. The conductor material may be, for example, aluminum or copper.

In some embodiments, the junction housing 2 may be a housing in a junction box assembly of a power track. The terminal block assembly may also include a wiring assembly that may be connected to an electrode conductor (e.g., an E-pole conductive strip 411 described below) housed in the track housing 1 to connect the electrode conductor to a power circuit. The terminal housing 2 may be an insulating member for fixing a terminal assembly (e.g., an E-pole terminal connector 412 described below) to ensure stable and reliable connection between the electrode conductive member and the terminal assembly.

In some embodiments, as shown in fig. 1, the junction housing 2 includes a mount 21 and a box 22. The fixing frame 21 at least partially covers the end of the accommodating cavity 11, the first fastener 3 fixedly connects the rail housing 1 and the fixing frame 21, the box 22 is covered on the outer side of the fixing frame 21, and the box 22 is respectively connected with the fixing frame 21 and the rail housing 1. Through the box body 22 cover is established in the outside of mount 21, can avoid electrode electrically conductive piece such as E utmost point electrically conductive piece 4 and wiring subassembly to expose outside, reduce the security risk.

In some embodiments, the first fastener 3 resiliently abuts the E-pole conductive member 4. In this way, the connection stability between the first fastening piece 3 and the E-pole conductive piece 4 can be improved, and the grounding stability of the power rail is further ensured.

In particular embodiments, the E-pole conductive member 4 may be made of an elastic material to provide an elastic abutment with the first fastener 3, or the E-pole conductive member 4 may include a deformable abutment structure by which an elastic abutment with the first fastener 3 is achieved. The deformable abutment structure may be, for example, a bent structure.

In some embodiments, as shown in fig. 2 and 3, the first fastener 3 has external threads 311, and the e-pole conductive member 4 has a threaded structure 4221, and is threadably coupled to the first fastener 3 by the threaded structure 4221. In this way, the external thread 311 on the first fastener 3 engages the E-pole conductive member 4, increasing the contact area between the first fastener 3 and the E-pole conductive member 4 and the connection stability.

In some embodiments, as shown in fig. 3, the first fastener 3 is a screw and the E-pole conductive member 4 is in contact with at least one of a stud 31 and a nut 32 of the screw. The fixed connection between the track shell 1 and the wiring shell 2 and the electric connection between the E-pole conductive piece 4 and the track shell 1 are realized simultaneously through screws, so that the cost is low.

In this way, the contact area between the E-pole conductive piece 4 and the first fastening piece 3 is increased, and the first fastening piece 3 can be abutted against the E-pole conductive piece 4 from different directions, so that the connection stability between the E-pole conductive piece and the first fastening piece is improved.
