[0036] 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 creative efforts shall fall within the protection scope of the present utility model.

[0037] Please refer to Figures 1-3 , a new type of rubber sheath for automotive wiring terminals of the present utility model, includes a sheath body, and the sheath body includes the following components;

[0038] Root of the sheath 1: The root of the sheath 1 is a cylindrical structure, and the root of the sheath 1 is provided with a terminal hole 3 for corresponding to the connection part of the wiring terminal;

[0039] Wire entry terminal 2: The wire entry terminal 2 is located above the sheath root 1, and the sheath root 1 is an arc-shaped structure. The wire entry terminal 2 is provided with a wire entry hole 8 for the wire to pass through;

[0040] Sheath groove 4: At least one sheath groove 4 is provided on the side of the sheath root 1, and the sheath groove 4 is used to cooperate with a terminal block or other fixed structures.

[0041] The preferred embodiment of the above-mentioned novel rubber sheath for automobile terminal is:

[0042] Design of opening 6 of line entry terminal 2:

[0043] Working principle: The opening 6 designed in the upper part of the wire entry end 2 allows the wire to be initially positioned after passing through the wire entry hole 8. When the wire enters the inside of the sheath through the wire entry hole 8, the existence of the opening 6 provides a preliminary guide for the wire, allowing it to smoothly enter and remain in the predetermined position, thereby improving the convenience and accuracy of installation.

[0044] The connection design between the bayonet 7 and the opening 6:

[0045] Working principle: In the upper part of the inlet terminal 2, in addition to the opening 6, there is also a bayonet 7 connected to the opening 6. This design allows the wire to be further fastened through the bayonet 7 after passing through the opening 6 and completing the initial positioning. The bayonet 7 is usually designed to have an elastic or adjustable structure, which can tightly wrap the wire to prevent it from loosening or falling off during use, thereby enhancing the stability and safety of the electrical connection. After the line is introduced into the inlet terminal 2 through the bayonet 7 and the opening 6, a tie band can be tied at the inlet terminal 2 to further fix the line.

[0046] The protective lines on the inner wall of the opening 6 and the bayonet 7:

[0047] Working principle: Providing protective patterns (such as anti-skid patterns, anti-skid grooves, etc.) on the inner walls of the opening 6 and the bayonet 7 can increase the friction between the wire and the cable, further ensuring the stability of the wire in the sheath. At the same time, these patterns can also protect the wire surface from wear or scratches to a certain extent, extending the service life of the wire and the entire electrical system.

[0048] Design of the adjusting sleeve 5 at the root 1 of the sheath:

[0049] Working principle: The root 1 of the sheath is provided with an adjustment sleeve 5, which is inserted into the root 1 of the sheath by interference fit to achieve a tight connection with the sheath. The terminal hole 3 is provided on the adjustment sleeve 5 and runs through the entire adjustment sleeve 5. This design allows the position and size of the terminal hole 3 to be designed on the adjustment sleeve 5 as needed to adapt to terminal blocks of different specifications and models. At the same time, due to the close fit between the adjustment sleeve 5 and the sheath, the stability and sealing of the entire sheath structure are also enhanced.

[0050] Anti-slip texture on the inner wall of terminal hole 3:

[0051] Working principle: Providing anti-slip patterns on the inner wall of the terminal hole 3 can increase the friction between the terminal and the wiring terminal, ensuring that the wiring terminal can be firmly fixed in place after being inserted into the terminal hole 3. This design effectively prevents the risk of the wiring terminal loosening or falling off due to vibration or external force during use, and improves the reliability and safety of the electrical connection.

[0052] The utility model introduces a new type of automotive terminal rubber sheath, the main purpose of which is to protect the terminal in the automotive electrical system and ensure a stable connection between the wire and the terminal. The sheath achieves effective protection and positioning of the wire and the terminal through its unique design structure, and improves the reliability and safety of the electrical connection.

[0053] Working principle of the sheath body and each component:

[0054] Sheath root 1:

[0055] Structure: The root 1 of the sheath is designed as a cylindrical structure, which is easy to match with the terminal block in the automotive electrical system, ensuring that the sheath can be stably fitted on the terminal block during installation.

[0056] Function: The terminal hole 3 provided at the root 1 of the sheath is specially designed to correspond to the connecting part of the wiring terminal. When the wiring terminal is inserted into the terminal hole 3, the two can fit tightly to form a stable electrical connection.

[0057] Incoming line 2:

[0058] Structure: The wire entry end 2 is located above the sheath root 1 and is designed as an arc structure. This design is not only beautiful, but more importantly, it can adapt to wire access at different angles, improving the flexibility of use.

[0059] Function: The wire entry hole 8 provided on the wire entry end 2 is a passage for the wire to enter the sheath. After the wire enters the sheath through the wire entry hole 8, it can be effectively fixed at a predetermined position to prevent it from loosening or falling off during use.

[0060] Sheath slot 4:

[0061] Structure: At least one sheath groove 4 is provided on the side of the root of the sheath 1, and the size and shape of these grooves are determined according to actual needs.

[0062] Function: The main function of the sheath groove 4 is to cooperate with the terminal block or other fixing structures to achieve precise positioning and stable installation of the sheath. When the sheath is installed on the terminal block, the sheath groove 4 can match the corresponding structures (such as protrusions, card slots, etc.) on the terminal block to ensure that the sheath will not be displaced or fall off during use. This design also simplifies the installation process and improves the installation efficiency.

[0063] In summary, through the unique design of the root of the sheath 1, the wire inlet end 2 and the sheath groove 4, the new rubber sheath for automotive terminal realizes effective protection and stable connection of the wire and the terminal. Its working principle is simple and efficient, and can significantly improve the overall performance and safety of the automotive electrical system.
