When in use, the U-shaped clamp 3 equipped with the flexible composite contact finger 4 and the conductive copper bus 5 are inserted into the molded case base 1 and fixed. The conductive copper bus 5 is formed by bending the copper bus, and then undergoes surface electroplating. It has low cost and excellent conductivity, and plays the role of connecting the flexible composite contact finger 4 with the internal conductive copper bus 5 to form a closed loop.

After fixing, a certain gap is left between the flexible composite contact fingers in the product, and this gap can meet the thickness of the plug bar.

[0055] The advantages of this product:

[0056] 1) Excellent conductivity, low cost, easy installation and disassembly;

[0057] 2) Strong current carrying capacity, suitable for modular conductive connection in a small space;

[0058] 3) Strong installation tolerance and sufficient conductive contact force;

[0059] 4) Lightweight design, reliable and firm positioning and installation;

[0060] 5) Able to withstand long-term vibration in working state;

[0061] 6) Long service life, plugging and unplugging can reach more than 1000 times;
