After the sleeve is completed, the multiple convex strips are correspondingly located in the multiple grooves, so that the cooperation between the convex strips and the grooves is utilized to form multiple sealing protections, thereby improving the waterproof performance of the terminal.

[0007] Optionally, the thicknesses of the plurality of convex strips are not all the same.

[0008] By adopting the above technical solution, the waterproof effect of the sheath is ensured while the connecting piece and the protective piece have a higher structural strength.

[0010] By adopting the above technical solution, on the one hand, it is convenient to connect the protective member to the connecting member, and on the other hand, it also reduces the risk of wear of the convex strip when the protective member moves relative to the connecting member.

[0011] Optionally, the connecting member further comprises a limiting ring, and the limiting ring is sleeved on the plurality of movable parts when the convex strip abuts against the bottom of the groove.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiment of the present application discloses a waterproof rubber plugging sleeve for a wiring terminal.

[0032] Example 1

[0033] Reference Figure 1 A waterproof rubber plugging sleeve for a terminal comprises a connector 1 and a protective sleeve 2, wherein the connector 1 is used to connect to the terminal, and the protective sleeve is connected to the connector 1. The connector 1 is provided with a plurality of grooves 11, and the plurality of grooves 11 are arranged at intervals along the length direction of the wiring harness. The inner wall of the protective sleeve 2 is provided with a plurality of ridges 21, and the side walls of the ridges 21 are used to abut against the bottom of the grooves 11, and the plurality of ridges 21 correspond one to one with the plurality of grooves 11. After the wiring harness is connected to the wire terminal, the connector 1 is connected to the end of the terminal, and the protective sleeve 2 is sleeved on the connector 1. After the sleeve is completed, the plurality of ridges 21 are correspondingly located in the plurality of grooves 11, thereby utilizing the cooperation between the ridges 21 and the grooves 11 to form multiple sealing protections and improve the waterproof performance of the terminal.

[0034] The connector 1 and the connection terminal may be fixed by bonding, welding or integrally formed.

[0035] The convex strip 21 and the protective member 2 may be fixed by bonding, welding or integrally formed. In this embodiment, the convex strip 21 is made of rubber to facilitate the sleeve of the protective member 2 on the connecting member 1, and the protective member 2 is made of plastic. The convex strip 21 and the protective member 2 are integrally formed to ensure the connection stability between the convex strip 21 and the protective member 2.

[0036] Furthermore, the thicknesses of the plurality of convex strips 21 are not completely the same, that is, the depths of the plurality of grooves 11 are not completely the same, thereby ensuring the waterproof effect of the sheath while making the connector 1 and the protective member 2 have a higher structural strength.

[0037] In this embodiment, the thickness of the plurality of convex strips 21 increases first and then decreases from one end to the other end of the protective member 2 , thereby ensuring the waterproof effect of the sheath while taking into account the convenience of connection between the protective member 2 and the connecting member 1 .

[0038] The implementation principle of Example 1 is as follows: a connector 1 with multiple grooves 11 is connected to the end of the terminal block, a protective member 2 with multiple ridges 21 is sleeved on the connector 1, and multiple ridges 21 cooperate with multiple grooves 11 to achieve multiple sealing, thereby improving the waterproof performance of the terminal block.

[0039] Example 2

[0040] Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the connector 1 includes an abutting portion 12, a movable portion 13 and a limiting ring 14, the abutting portion 12 is used to abut against the end of the connector 1, and a plurality of movable portions 13 are hinged to the abutting portion 12, and the plurality of movable portions 13 are arranged along the circumference of the abutting portion 12. After completing the connection between the wiring harness and the wire terminal, the abutting portion 12 is moved relative to the wiring harness so that the abutting portion 12 abuts against the connecting portion, and then the movable portion 13 is rotated relative to the abutting portion 12 so that the plurality of convex strips 21 respectively enter the corresponding grooves 11, and then the adhesive can be filled in the gap between the protective member 2 and the connector 1 to complete the connection between the protective member 2 and the connector 1, thereby facilitating the connection of the protective member 2 to the connector 1 on the one hand, and reducing the risk of the convex strips 21 being worn when the protective member 2 moves relative to the connector 1 on the other hand.

[0041] In this embodiment, a limiting ring 14 is used to limit the multiple movable parts 13. When the convex strip 21 abuts against the bottom of the corresponding groove 11, the limiting ring 14 is sleeved on the multiple movable parts 13. The structure is simple, the operation is convenient, and it is also convenient for the reuse of the protective part 2.

[0042] Furthermore, the thickness of the movable part 13 gradually increases from one end close to the abutting part 12 to the other end, so that the limiting ring 14 gradually deforms during the process of being sleeved on the movable part 13, thereby increasing the abutting force between the limiting ring 14 and the movable part 13, and then increasing the abutting force between the protective part 2 and the connecting part 1, thereby ensuring the waterproof performance of the sheath.

[0043] Furthermore, in this embodiment, a limiting groove 131 is provided on the surface of the movable portion 13 facing away from the connecting member 1, and the bottom of the limiting groove 131 is used for abutment by the limiting ring 14, so that the limiting groove 131 is used to limit the limiting ring 14, thereby reducing the risk of the limiting ring 14 falling off the protective member 2.

[0044] Example 3

[0045] Reference Figure 4 The difference between this embodiment and the embodiment 1 is that the protective member 2 includes an abutting layer 22, a water absorbing layer 23 and an outer shell layer 24, the convex strip 21 is arranged on the abutting layer 22, the water absorbing layer 23 is connected to the surface of the abutting layer 22 away from the connector 1, and the outer shell layer 24 is connected to the surface of the water absorbing layer 23 away from the abutting portion 12. With this design, when the air around the terminal is relatively humid, the water around the terminal is absorbed to a certain extent by the water absorbing layer 23, thereby reducing the risk of water entering the interior of the terminal. At the same time, after absorbing a certain amount of water, the volume of the water absorbing layer 23 increases, thereby increasing the abutting force between the abutting layer 22 and the connector 1, thereby enhancing the sealing performance of the sheath.

[0046] The water absorbing layer 23 and the abutting layer 22 are bonded and fixed, and the outer shell layer 24 and the water absorbing layer 23 are bonded and fixed.

[0047] In this embodiment, the water absorbing layer 23 is made of sponge, which has a high water absorbing efficiency on one hand, but will also undergo a large deformation after absorbing water on the other hand.

[0048] Furthermore, the side walls of the water absorbing layer extend into the external air, thereby improving the water absorbing efficiency of the water absorbing layer.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
