The round hole for the outgoing line is provided with a protective coil. The inner side of the shell cover is provided with a waterproof silicone strip, and the end of the shell cover is provided with a box lock. Connect the outer casing and the casing cover through the ground wire, and connect the outer casing and the busway through the installation clip.

Preferably, the pins are copper pins, and copper tabs are exposed through the bottom of the outer casing, and the length of the copper tabs is 1-2 cm.

As a preference, conductive sheets are provided at the lower ends of both sides of the conductive block of the plug-in box, and the length of the conductive sheet is 2-3 cm.

Preferably, the spring is installed on one side of the pin, connected to the copper tab of the pin, and the elastic force of the spring is controlled by the adjusting nut.

The utility model has the following beneficial effects:

(1) Simple structure and easy installation;

(2) By setting the spring at the pin position, the poor contact between the copper tab and the conductive copper bar is solved, and the energy saving effect is achieved;

(3) The use safety and service life of the plug-in box are improved, and the service life of the busway is improved.
