[0002] The ends of wires often have exposed cores, especially at the wire connectors of multiple wires, where the cores are obviously exposed and require necessary insulation protection.

[0003] When performing insulation protection on multi-strand wire joints: first, the wire joints are tied and then tinned, and then wrapped with high-pressure tape and black tape in sequence. This method has low work efficiency, and after a long time, the tape ages and exposes the wire joints, causing short circuits with other lines; the second method is to use terminal caps for crimping. However, when traditional terminal caps are used to press the multi-strand wire joints, the multi-strand wires need to be rotated and tightened by the terminal caps so that the multi-strand wires are tightly wound together to achieve connection stability, which makes the connection method inconvenient.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-2 In this embodiment, a plug-in insulating spring wiring cap includes an insulating cap body 1, a connecting block 2 is slidably connected to the inner side of the insulating cap body 1, and a connecting piece 3 is provided on the insulating cap body 1; there are two connecting blocks 2, both of which are semi-cylindrical, and a connecting groove 38 is opened on the inner side of the connecting block 2.

[0023] In this embodiment, the two connecting blocks 2 are brought closer together by the connecting member 3 , and the connecting grooves 38 on the connecting blocks 2 squeeze the multiple wires to achieve plug-in fixation of the multiple wires.

[0024] It should be noted that

[0025] See also Figure 1-4 In this embodiment, the connecting piece 3 includes a support rod 37 at one end that passes through the insulating cap body 1 and is slidably connected to the insulating cap body 1. The support rod 37 is located at one end on the inner side of the insulating cap body 1 and is fixedly connected to the connecting block 2. A connecting spring 33 is fixedly connected between the outer side of the connecting block 2 and the inner wall of the insulating cap body 1. The outer side of the insulating cap body 1 is slidably connected to a movable ring 31 located on the outer side of the support rod 37. The inner side wall of the insulating cap body 1 is rotatably connected to a rotating block 34. The outer side of the rotating block 34 is hinged to a connecting rod 32 with one end hinged to the lower end of the movable ring 31. The outer side of the movable ring 31 is fixedly connected to a hinge block 35. The inner side of the hinge block 35 is rotatably connected to a limit rod 36 with one end passing through the movable ring 31 and extending to the inside of the insulating cap body 1.

[0026] In this embodiment, the movable ring 31 slides down and squeezes the top limit groove of the limit rod 36, and the connecting rod 32 drives the rotating block 34 to squeeze the connecting blocks 2 on both sides close together, so that the multiple wires can be tightly squeezed and fixed on the inner side of the connecting groove 38. When the limit rod 36 is squeezed into the bottom limit groove as the movable ring 31 slides down, the multiple wires can be locked to fix the connection between the wire cap and the wire to improve the convenience of connection.

[0027] Among them, the inner wall of the insulating cap body 1 is provided with a support hole located on the outside of the support rod 37. The support hole is convex in shape. The connecting spring 33 is fixedly connected between the support hole and the connecting block 2 and is located on the outside of the support rod 37. The support of the connecting block 2 by the support rod 37 enables the connecting block 2 to slide stably on the insulating cap body 1 and be reset by the connecting spring 33.

[0028] In addition, the inner wall of the insulating cap body 1 is provided with a rectangular hole located outside the rotating block 34. The inner side of the rectangular hole is rotatably connected to a rotating shaft. The rotating block 34 is rotatably connected to the inner side of the rectangular hole through the rotating shaft, so that the rotating block 34 can rotate through the rotating shaft in the rectangular hole.

[0029] Secondly, the upper and lower ends of the movable ring 31 are both provided with grooves 39 located outside the support rod 37, and the middle part of the movable ring 31 is provided with a through hole located outside the limit rod 36, so that the movable ring 31 sliding up and down is not blocked by the support rod 37.

[0030] Then, the inner side of the hinge block 35 is rotated to connect the connecting shaft, and the limiting rod 36 is rotated to connect the inner side of the hinge block 35 through the connecting shaft. A torsion spring is provided between the limiting rod 36 and the hinge block 35, so that the hinge block 35 can rotate inside the hinge block 35 and be reset by the torsion spring.

[0031] Next, one end of the limiting rod 36 passing through the movable ring 31 is L-shaped, and the L end of the limiting rod 36 is inclined. The movable ring 31 is limited and fixed by extending the limiting rod 36 in the insulating cap body 1.

[0032] Finally, a limiting groove is opened on the outside of the insulating cap body 1. There are four limiting grooves, which are symmetrically distributed in groups of two. The limiting rod 36 extending into the bottom limiting groove is used to limit the sliding movable ring 31, and the limiting rod 36 extending into the top limiting groove can limit the reset movable ring 31.

[0033] The working principle of the above embodiment is:

[0034] After the multiple strands of wire are plugged into the connection groove 38 of the connection block 2, the sliding movable ring 31 squeezes the top limit groove of the limit rod 36, and drives the rotating block 34 to squeeze the connection blocks 2 on both sides closer through the connecting rod 32, so that the multiple strands of wire can be tightly squeezed and fixed on the inner side of the connection groove 38. When the limit rod 36 is squeezed into the bottom limit groove as it slides down with the movable ring 31, the multiple strands of wire can be locked to fix the connection between the wire cap and the wire, so as to improve the convenience of connection.
