[0023] In the prior art, a clamping block and a return spring are typically placed on the terminal protective cover, and a groove is placed on the surface of the terminal. The return spring pushes the clamping block into the groove to achieve the installation and fixation of the terminal protective cover on the outside of the terminal. The structure of the terminal protective cover in the prior art is relatively complex, and during the transportation of the terminal with the terminal protective cover, the return spring on the terminal protective cover is easily damaged by bumps, which can cause the terminal protective cover to fall off the terminal surface.

[0024] In view of the fact that the existing terminal protection cover has a complex structure, the present application proposes a terminal protection cover and a wiring harness device to overcome the above problem.

[0025] The following describes a terminal protection cover and a wiring harness device provided by the present application in conjunction with the accompanying drawings.

[0026] In some embodiments, please refer to Figure 1 The present application proposes a terminal protection cover 1, which is provided with a receiving hole 12; the receiving hole 12 passes through the terminal protection cover 1 along the axial direction of the terminal protection cover 1; a hollow groove 10 is provided on the side wall of the terminal protection cover 1, and the hollow groove 10 connects the receiving hole 12 with the outside of the terminal protection cover 1, and a clip 11 is provided on the groove wall of the hollow groove 10; the clip 11 extends along the through direction of the receiving hole 12 and has a connecting end 111; the connecting end 111 of the clip 11 is connected to the groove wall of the hollow groove 10, and the rest of the clip 11 is suspended in the hollow groove 10.

[0027] In some embodiments, please refer to Figure 2 The terminal protection cover 1 comprises a first portion 13, a second portion 14, and a connecting portion 15 connecting the first and second portions 13, 14. The receiving hole 12 extends through the first, second, and connecting portions 15. The outer diameter of the connecting portion 15 gradually decreases from the second portion 14 to the first portion 13. Specifically, the first portion 13 and the second portion 14 have a cylindrical structure, and the connecting portion 15 has a frustum.

[0028] In some embodiments, please refer to Figure 2 A protruding ring 16 is provided on the wall of the receiving hole 12 located in the first portion 13. The protruding ring 16 is located at the end of the first portion 13 facing away from the second portion 14. The protruding ring 16 extends from the wall of the first portion 13 to the center of the first portion 13. The inner diameter of the protruding ring 16 is smaller than the diameter of the receiving hole 12 located in the first portion 13.

[0029] In some embodiments, please refer to Figure 2 The first portion 13 has an end surface 17 facing away from the second portion 14. The hollow groove 10 has a first end 101 and a second end 102 opposite to each other in the extending direction thereof. The first end 101 passes through the end surface 17, and the second end 102 extends to the second portion 14. The second end 102 does not pass through the end surface of the second portion 14 facing away from the first portion 13, and a gap is formed between the second end 102 and the end surface of the second portion 14 facing away from the first portion 13.

[0030] In some embodiments, please refer to Figure 3The clamping member 11 has a free end 110 that is away from the connecting end 111 , the connecting end 111 is connected to the second end 102 of the hollow groove 10 , and the free end 110 extends to the connecting portion 15 .

[0031] In some embodiments, please refer to Figure 4 The extension trajectory of the clamping member 11 is the same as the extension trajectory of the terminal protection cover 1. Specifically, the clamping member 11 has a third portion 112 located at the second portion 14 and a fourth portion 113 located at the connecting portion 15. The extension trajectory of the clamping member 11 in the third portion 112 is the same as the extension trajectory of the second portion 14, and the extension trajectory of the clamping member 11 in the fourth portion 113 is the same as the extension trajectory of the connecting portion 15.

[0032] In some embodiments, the clamping member 11 is made of an elastic material. The free end 110 of the clamping member 11 can be displaced radially outward of the terminal protection cover 1 after being squeezed. The clamping member 11 and the terminal protection cover 1 are integrally formed.

[0033] In some embodiments, please refer to Figure 5 、 Figure 6 、 Figure 7 The present application proposes a wiring harness device, which includes a terminal protection cover 1 and a terminal 2 as described in any of the above embodiments; a snap-fit ​​groove 20 is provided on the outer periphery of the terminal 2 and is passed through the accommodating hole 12; the free end 110 of the snap-fit ​​member 11 is engaged with the snap-fit ​​groove 20 to fit the terminal protection cover 1 and fix it on the outside of the terminal 2.

[0034] In some embodiments, please refer to Figure 5 The outer periphery of the terminal 2 is provided with a first limiting ring 21 and a second limiting ring 22 arranged at intervals, and the interval between the first limiting ring 21 and the second limiting ring 22 is used to form the clamping groove 20.

[0035] In some embodiments, the thickness of the connecting portion 15 and the thickness of the second portion 14 may be greater than the thickness of the first portion 13 to enhance the strength of the terminal protection cover 1 .

[0036] In some embodiments, during the transportation of the terminal 2, the terminal protection cover 1 can be put on and fixed to the outside of the terminal 2. The terminal protection cover 1 provides protection for the terminal 2 to prevent the terminal 2 from being damaged and deformed due to external force during transportation.

[0037] In some embodiments, the terminal 2 passes through the end face of the second portion 14 facing away from the first portion 13 and enters the receiving hole 12. During the process of the terminal 2 entering the receiving hole 12, the first limiting ring 21 squeezes the free end 110. After being squeezed, the free end 110 is displaced radially outward of the terminal protection cover 1. The first limiting ring 21 passes through the free end 110 from the inner side of the free end 110 along the axial direction of the terminal protection cover 1. Then, the terminal 2 continues to move toward the terminal protection cover 1. The first limiting ring 21 no longer squeezes the free end 110, and the free end 110 is reset, thereby allowing the free end 110 to engage with the engaging groove 20, so that the terminal protection cover 1 is sleeved and fixed to the outside of the terminal 2.

[0038] In some embodiments, please refer to Figure 8 The terminal 2 includes a metal cover 23 and an insulator 24; the insulator 24 is arranged inside the metal cover 23; the convex ring 16 of the terminal protection cover 1 covers the metal cover 23, and the insulator 24 is exposed inside the convex ring 16; the inner diameter of the convex ring 16 is greater than or equal to the aperture of the metal cover 23. An electrical connection structure is provided inside the insulator 24 for transmitting signals. Based on this, the convex ring 16 can prevent dust and debris from entering the gap between the metal cover 23 and the hole wall of the first part 13, thereby ensuring the stability of the terminal 2 when transmitting signals; further, the convex ring 16 can provide protection for the metal cover 23 to prevent the metal cover 23 from being deformed by impact along the axial direction of the terminal protection cover 1.

[0039] Based on the above embodiment, the terminal protective cover can be mounted and fixed to the exterior of the terminal by engaging the free end of the clamping member with the clamping groove of the terminal, thereby providing protection for the terminal. Furthermore, the hollowed-out groove allows a mating device with a testing function to be connected to the terminal, allowing testing to be performed with the terminal protective cover in place without having to remove it, thus facilitating testing.

[0040] In summary, although the present application has been disclosed as above with preferred embodiments, the above preferred embodiments are not intended to limit the present application. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims.
