The fixing strap 21 is used to fix and support the electrical terminal and the connecting wire. The opening 12 is used to facilitate the electrical terminal to be buckled into the insulating protection cap 1.

[0027] Secondly, as shown in Figure 1 , Figure 5 and Figure 6 As shown in the figure, first adhesive layers 23 are fixedly connected to the inner walls on both sides of the opening 22.

The first protective layer 24 is used to protect the first adhesive layer 23.

[0028] Furthermore, as shown in Figure 1 and Figure 2 As shown in the figure, a second adhesive layer 31 is fixedly connected to the lower surface of the insulating binding strap 3. The second adhesive layer 31 is located at the position of the insulating binding strap 3 away from the fixing strap 21. A second protective layer 32 is fixedly connected to the side wall of the second adhesive layer 31 away from the insulating binding strap 3. The insulating binding strap 3 is used to fix the electrical terminal and the connecting wire. The second adhesive layer 31 is used to fix the position of the insulating binding strap 3. The second protective layer 32 is used to protect the second adhesive layer 31.

[0029] Still further, as shown in Figure 1 , Figure 3 and Figure 4As shown, a fixing component 4 is provided on the opening side of the insulation protection cap 1.

Apply adhesive between the insulating outer ring 40 and the insulating inner ring 42. Then, complete the connection of the electrical terminal with the connecting wire and the connecting column, and insert the electrical terminal and the connecting wire into the insulation protection cap 1 and the insulating connection cylinder 2 from the second opening 22 and the hollow ball cap 11. Snap the insulation protection cap 1 between the insulating outer ring 40 and the insulating inner ring 42 to make the insulation protection cap 1 closely contact with the adhesive layer 43. After the insulation protection cap 1 and the adhesive layer 43 are fixed together, wind the insulating strap 3 tightly around the electrical terminal, the connecting wire, the insulating connection cylinder 2, and the fixing strap 21, and tear off the second protective layer 32 to fix the insulating strap 3 with the second adhesive layer 31, so that the electrical terminal and the connecting wire are firmly fixed on the inner walls of the insulating connection cylinder 2 and the fixing strap 21.
