The clamping groove of the limit clamp 6 matches the outer diameter of the insulating shell 1. One end of the telescopic rod 7 is connected to the limit clamp 6, and the other end is connected to a pressure head 9. The pressure head 9 is a semicircular structure. The telescopic rod 7 is matched with a spring 8.

[0035] like Figure 2 As shown, an insulating layer 31 is provided on the outer side of the terminal 3 .

[0036] Principle and operation process

[0037] The utility model adopts a quick connector 4 with a newly designed clamping device, which can achieve a fast and firm connection operation when wiring cables. The terminal post 3 in the form of a quick connector 4 can be quickly installed during installation, speeding up the construction progress; an insulating layer 31 is arranged on the outside of the terminal post 3, which can better prevent the risk of electric shock to the operator and improve the safety during the installation process; the clamping device can complete the clamping operation by pressing down the limit clamp 6 when in use, and rotating the limit clamp 6 to clamp it on the shell after it is in place, which also reduces the protruding part on the shell and avoids the clamping device from falling off due to unintentional collision; a limit protrusion 61 is also arranged on the limit clamp 6, which can improve the stability of the limit clamp 6 after clamping, and can prevent it from falling off due to external contact. At the same time, the edge of the limit protrusion 61 is designed with a rounded corner. When it needs to be removed, it can be turned slightly with force, and the limit protrusion 61 can slide out of the groove to complete the disassembly;

[0038] The specific operation is as follows: when in use, first insert the two outer shells into the two cables to be connected respectively, then peel the front end of the cable, insert it into the quick connector 4, screw the insulating threaded sleeve 5 until the cable is clamped, then move the outer shell to the terminal seat 2, screw it on the threaded connector 21, and after tightening, the wiring operation on the other side adopts the same method; before connecting the outer shells, it should be noted that the cable must be passed between the pressure heads 9 of the two clamping devices. After the outer shells are connected, the limiting clamps 6 on both sides are pressed down at the same time. When the slot on the limiting clamp 6 reaches a position flush with the outer shell wall, the limiting clamp 6 is rotated 90 degrees and the slot is clamped on the outer shell wall. The spring 8 will press the pressure head 9 on the cable, and the telescopic rod 7 can play a guiding and limiting role on the spring 8. After the connection, the fixing of the clamping device can effectively prevent the virtual electricity phenomenon caused by touching the line, thereby improving the wiring quality.

[0039] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
