The connecting mechanism includes a conductive plate 12. The bottom of the conductive plate 12 is fixedly provided with an insulating plate 10. The insulating plate 10 is slidably installed inside the installation groove 7 through a fixing rod 8.

The insulating plate 10, the insulating box 1 and the insulating cover 2 can improve the insulation of the device.

[0023] In this embodiment, the fixing rods 8 are symmetrically and fixedly installed on both sides inside the installation groove 7. The insulating plate 10 is slidably installed on the fixing rods 8 through sliding holes. A spring 9 is fixedly installed outside the bottom end of the fixing rod 8 corresponding to the bottom of the installation groove 7. The top end of the spring 9 is fixedly connected to the bottom of the insulating plate 10. Through holes 14 are opened at the positions corresponding to the fixing rods 8 inside both ends of the conductive plate 12. The fixing rods 8 are slidably installed inside the through holes 14. The provided fixing rods 8 can limit the insulating plate 10 and the conductive plate 12, facilitating the lifting and sliding of the insulating plate 10 and the conductive plate 12. By providing the spring 9, an elastic force is generated when the insulating plate 10 and the conductive plate 12 move downward, facilitating the subsequent extrusion and fixing of the wire noses 11, so that the wire noses 11 are in stable contact with the conductive plate 12.

[0024] In this embodiment, the wire nose 11 is sleeved on the top end of the fixing rod 8. The wire nose 11 is arranged on the top of the conductive plate 12. Concave grooves are formed at both sides of the bottom of the insulating cover 2 corresponding to the positions of the arc grooves 5. Elastic rubber pads 13 are fixedly arranged inside the concave grooves and the arc grooves 5. One end of the wire nose 11 is electrically and fixedly connected to a connecting wire 6. The connecting wire 6 is installed inside the arc groove 5 and the concave groove. The elastic rubber pad 13 is arranged on the outer side of the connecting wire 6. By sleeving the fixing rod 8 with the wire nose 11, it is convenient to position and install the wire nose 11.
