Detailed Implementation

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0023] The conductive clip assembly structure in this embodiment of the utility model is as follows: Figures 1 to 4 As shown, it includes a conductive busbar 1, preferably made of copper. Clamping assemblies 2 are symmetrically arranged on both sides of the front end of the conductive busbar 1. Each clamping assembly 2 includes a first conductive clamp 21 that is attached to and fixedly connected to the side of the conductive busbar 1, a second conductive clamp 22 fixed to the side of the first conductive clamp 21 facing away from the conductive busbar 1, and a support piece 23 fixed to the side of the second conductive clamp 22 facing away from the conductive busbar 1. The first conductive clamp 21 has a first elastic contact arm 24 extending forward from the front edge 10 of the conductive busbar 1, and the second conductive clamp 22 has a second elastic contact arm 25 extending forward from the front edge 10 of the conductive busbar 1. The first elastic contact arm 24 and the second elastic contact arm 25 are staggered in the left-right direction. The support plate 23 is provided with a support arm 231 that abuts against the outer side of the elastic contact arm 24 and a support arm 232 that abuts against the outer side of the elastic contact arm 25. In use, when the conductive insert is inserted between the two clamping assemblies 2, the support arm 231 and the support arm 232 can apply pressure to the elastic contact arm 24 and the elastic contact arm 25, thereby increasing the clamping force of the elastic contact arm 24 and the elastic contact arm 25. This allows the elastic contact arm 24 and the elastic contact arm 25 to form a reliable elastic contact with the side of the conductive busbar 1, thereby electrically connecting the conductive insert to the conductive busbar 1. Since multiple elastic contact arms 24 and multiple elastic contact arms 25 can increase the contact surface, the electrical conductivity is effectively improved.

[0024] like Figure 5As shown, the conductive clamp piece 21 is provided with a plurality of elastic arms 24 spaced apart in the left-right direction, and a clearance 210 is formed between two adjacent elastic arms 24. A plurality of elastic arms 25 are arranged at the clearance 210, so as to prevent the elastic arms 24 and the elastic arms 25 from interfering with each other, and to ensure the use performance.

[0025] As shown in the drawings, Figures 2 to 5 The length of the elastic arm 24 is greater than the length of the elastic arm 25, and a contact foot 241 is formed at the end of the elastic arm 24, and a contact foot 251 is formed at the end of the elastic arm 25. The distance between the contact foot 241 and the front edge 10 is greater than the distance between the contact foot 251 and the front edge 10. Thus, the contact feet 241 and 251 are not only staggered in the left-right direction, but also staggered in the front-back direction, so that the contact points are relatively dispersed, which is beneficial to heat dissipation. On this basis, it is preferred that the lengths of the elastic arms 24 are not all equal, and the lengths of the elastic arms 25 are not all equal, so as to further disperse the positions of the contact feet 241 and 251.

[0026] As shown in the drawings, Figure 1 In order to facilitate positioning of the conductive strip 1, protruding positioning bosses 11 are arranged on the left and right sides of the conductive strip 1. The positioning bosses 11 are clamped in the clamping grooves of the mounting positions to achieve positioning of the conductive strip 1.

[0027] As shown in the drawings, Figure 3 and Figure 5 In order to achieve fixed connection between the conductive strip 1, the conductive clamp piece 21, the conductive clamp piece 22 and the support piece 23, rivet holes are arranged at corresponding positions of the conductive strip 1, the conductive clamp piece 21, the conductive clamp piece 22 and the support piece 23. Fixed rivets 12 are arranged in the rivet holes. The fixed rivets 12 are clamped to achieve fixed connection of the components. It is preferred that the number of fixed rivets 12 is at least two.

[0028] As shown in the drawings, Figure 5 The support arms 231 and 232 in the embodiment are spring structures formed by stamping from the support piece 23. The structure is simple and feasible, and easy to process and produce.

[0029] In order to enhance the positioning effect during installation, a positioning spring 233 is formed by stamping from the support piece 23 in a direction opposite to the conductive clamp piece 21. The positioning spring 233 is at an angle with the support piece 23 and the end thereof extends rearwardly and obliquely. The positioning spring 233 can play a role of stop and limit during installation of the conductive clamp assembly.

[0030] Further, in order to facilitate the fixed and with external line connection, the conductive row 1 rear end is provided with fixed end 13, the fixed end 13 is provided with fixed hole 14, can be fixed and wired through the fixed screw through the fixed hole 14.

[0031] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The changes or variations extended from the essential spirit of the present application still belong to the protection scope of the present application.
