[0023] Combine Figure 1 As shown, the device body includes a transmitter body 1 and a back cover 3 , and a device compartment 7 is formed between the transmitter body 1 and the back cover 3 .

[0024] As described above, when using the device body, positive electrode post 8, negative electrode post 16 and two terminal posts provided by the present invention, the wire clamping segment 13 is electrically connected to the positive electrode post 8 or the negative electrode post 16 through the screw segment 10 and the connecting mechanism, thereby facilitating the external placement of the two wire clamping segments 13 on the outside of the device body. During verification, the two wire clamping segments 13 can be directly clamped on the outside of the device body without disassembling the device body.

[0025] Further, in order to prevent the clamp from sliding on the clamping section 13, refer to Figure 2-3 As shown, the outer periphery of the clamping segment 13 is provided with a plurality of anti-skid grooves 14 for preventing slipping. The plurality of anti-skid grooves 14 are evenly spaced along the axis of the clamping segment 13. When the clamp is clamped on the clamping segment 13, a portion of the clamp is sunk into the anti-skid grooves 14, preventing the clamp from falling off the clamping segment 13.

[0026] In this utility model, combined with Figure 2-3 As shown, the outside of the device body of this embodiment is symmetrically provided with a first terminal block 2 and a second terminal block 4. The first terminal block 2 and the second terminal block 4 are both penetrated from the outside to the inside by a plug-in hole 17 connected to the equipment cabin 7. The screw segment 10 moves through the plug-in hole 17. The plug-in hole 17 includes two through holes with decreasing outer diameters from the outside to the inside. The connection between the wire clamping segment 13 and the screw segment 10 abuts against the connection between the two through holes from the outside to the inside.

The sealing caps 5 are detachably mounted on the first terminal block 2 or the second terminal block 4 via the externally threaded seats 15. At this time, the sealing caps 5 cover the exterior of the clamping segment 13 to prevent the clamping segment 13 from being accidentally touched when not in use. At the same time, the sealing gasket 6 provides a sealing effect in the gap between the sealing caps 5 and the externally threaded seats 15.

[0029] Further, in order to facilitate the connection between the positive pole 8 and the negative pole 16 and the corresponding clamping segment 13, refer to Figure 2-3 As shown, the connection mechanism includes a connecting wire 9 and a wire loop 12 mounted on one end of the connecting wire 9. The ends of the two connecting wires 9 facing away from the wire loop 12 are respectively mounted on the positive pole 8 and the negative pole 16. The wire loop 12 is sleeved on the screw segment 10. Both sides of the wire loop 12 are provided with a wire nut 11 that is screwed onto the screw segment 10. When the screw segment 10 is inserted from the outside to the inside through the insertion hole 17, one of the wire nuts 11 is tightened onto the screw segment 10 in the equipment compartment 7, thereby fixing the wire clamping segment 13 to the first terminal block 2 or the second terminal block 4. One end of the two connecting wires 9 is respectively mounted on the positive pole 8 and the negative pole 16. The wire loops 12 on the two connecting wires 9 are respectively sleeved on the two screw segments 10. Then, another wire nut 11 is screwed onto the screw segment 10. At this time, the wire loop 12 is clamped between the two wire nuts 11 and the screw segment 10.
