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

[0003] When insulating the joints of multiple-strand wires: one is to bind the wire joints well and then tin them, and then wrap them with high-voltage tape and black tape in sequence. Using this method, the work efficiency is low, and after a long time, the tape will age, causing the wire joints to be exposed and short-circuited with other circuits; the other is to use a wiring cap for crimping. However, when the traditional wiring cap crimps the joints of multiple-strand wires, due to the lack of locking measures, it is very easy to loosen and fall off, resulting in circuit breakage and affecting the crimping stability. Therefore, an insulating spring wiring cap which is convenient for installation is proposed to solve the above problems. Content of the Utility Model

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 Fig. 3 or 4, an insulating spring terminal cap convenient for installation in this embodiment includes an insulating cap body 1. An installation block 2 is rotatably connected to the inner side of the insulating cap body 1. A spring 3 is fixedly connected between the installation block 2 and the inner wall of the insulating cap body 1. A wiring groove 6 is opened at the upper end of the installation block 2. After multiple strands of wires pass through the installation block 2 and extend into the wiring groove 6, the insulating cap body 1 can be rotated to tighten the multiple strands of wires.

[0024] A connecting piece 4 is arranged on the insulating cap body 1.

[0025] In this embodiment, after the multiple strands of wires are pre-fixed by the installation block 2 on the inner side of the insulating cap body 1, the multiple strands of wires can be further locked by the connecting piece 4 to improve the connection stability.

[0026] Wherein, a second rotating shaft 5 is rotatably connected to the inner side wall of the insulating cap body 1. The installation block 2 is rotatably connected to the inner side of the insulating cap body 1 through the second rotating shaft 5. Since the installation block 2 rotates inside the insulating cap body 1 through the spring 3, after the multiple strands of wires pass through the installation block 2, they can be tightly pressed by the installation block 2.

[0027] Please refer to Figure 1-2 , in this embodiment, the connecting piece 4 includes a threaded ring 41 threadedly connected to the outer side of the insulating cap body 1 at one end. A connecting ring 42 is rotatably connected to the lower end of the threaded ring 41. A pressing rod 43 is fixedly connected to the lower end of the connecting ring 42. A rotating block 44 is rotatably connected to the inner side wall of the insulating cap body 1. A stabilizing block 45 is fixedly connected to the inner side of the rotating block 44.

[0028] In this embodiment, after the multiple strands of wires extending into the insulating cap body 1 are installed, rotated and pressed by the installation block 2, the threaded ring 41 can be rotated to squeeze the rotating block 44 through the pressing rod 43, and then the multiple strands of wires can be further pressed and tightened by the stabilizing block 45 on the inner side of the rotating block 44, and the wires are locked, reducing the possibility of the wires becoming loose, thereby improving the stability after the connection between the terminal cap and the multiple strands of wires.

[0029] Among them, the number of mounting blocks 2 and stabilizing blocks 45 is two each. The two mounting blocks 2 and stabilizing blocks 45 are symmetrically distributed inside the insulating cap body 1, and the multi-strand wires are pre-fixed and locked respectively by the two mounting blocks 2 and stabilizing blocks 45.

[0030] In addition, both the mounting block 2 and the stabilizing block 45 are conical. A stabilizing hole is provided at the lower end of the stabilizing block 45. After the stabilizing hole abuts against the multi-strand wire, the wire can be further stabilized.

[0031] Secondly, an installation hole 49 is provided on the inner side wall of the insulating cap body 1 outside the rotating block 44. A first rotating shaft 48 is rotatably connected inside the installation hole 49. The rotating block 44 is rotatably connected inside the installation hole 49 through the first rotating shaft 48. A torsion spring 47 is provided between the rotating block 44 and the inside of the installation hole 49, enabling the rotating block 44 to rotate inside the installation hole 49 and reset through the torsion spring 47.

[0032] Then, an external thread is provided on the outside of the insulating cap body 1, and the external thread cooperates with the thread on the inner wall of the thread ring 41, enabling the rotating thread ring 41 to move up and down and adjust on the outside of the insulating cap body 1.

[0033] Next, a first slider 46 is fixedly connected to the lower end of the thread ring 41, with one end extending inside the connection ring 42. A first sliding groove is provided at the upper end of the connection ring 42 outside the first slider 46. The first sliding groove is slidably connected to the first slider 46. The first slider 46 is T-shaped, and the first sliding groove is annularly distributed, enabling the rotating thread ring 41 to drive the connection ring 42 to move along and not separate from the connection ring 42.

[0034] Finally, a second slider 410 is fixedly connected to the inside of the connection ring 42, with one end extending inside the insulating cap body 1. A second sliding groove is provided on the outside of the insulating cap body 1 outside the second slider 410. The second sliding groove is slidably connected to the second slider 410, making the connection ring 42 move more stably when following the thread ring 41.

[0035] The working principle of the above embodiment is as follows:

[0036] After the multi-strand wire passes through the mounting block 2 and extends into the wiring groove 6, the insulating cap body 1 can be rotated to tighten the multi-strand wire. At this time, when the abutting rod 43 does not squeeze and abut against the rotating block 44, the rotating block 44 and the stabilizing block 45 are in an unfolded state, that is, rotating outside the insulating cap body 1. Then, by rotating the thread ring 41, the abutting rod 43 on the connection ring 42 can be driven to squeeze the rotating block 44. Then, through the stabilizing block 45 inside the rotating block 44, the multi-strand wire can be further abutted and pressed tightly, and the wire can be locked, reducing the possibility of the wire becoming loose. Thus, while improving the convenience of the connection between the wiring cap and the multi-strand wire, the connection stability can also be improved.
