Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a high-voltage and high-strength waterproof via connector for an on-board charger. Background Art

[0002] In the prior art, it is often found that cables often experience varying degrees of shaking when connected through holes. This is caused by a variety of factors, such as vibrations generated during device operation and slight external force, which may cause the cable to shake at the hole.

[0003] This continuous shaking, over time, is likely to cause tremendous pressure on the holes, leading to cracks. Once a hole is cracked, it will not only affect the overall structural stability of the equipment, but also cause a series of safety hazards, especially in on-board chargers.

[0004] Furthermore, this type of via connection is not waterproof in most cases. When the device is in a humid environment, or is accidentally splashed or immersed in water, moisture can easily enter the device through the vias, damaging the device's electronic components and seriously affecting its normal operation and service life. Utility Model Content

[0005] The main purpose of this utility model is to propose a high-voltage and high-strength waterproof through-hole connector for an on-board charger, aiming to improve the matching stability between the cable and the through-hole connector, positioning the wiring harness while also achieving waterproof performance.

[0006] To achieve the above objectives, the present invention proposes a high-voltage and high-strength waterproof via connector for an on-board charger, comprising:

[0007] A main body, wherein the main body extends forward to form a positioning seat, the positioning seat is penetrated by a restraining channel, the restraining channel is provided with a sealing ring, and the sealing ring is provided with a first positioning hole;

[0008] A cover body, which is detachably mounted on the positioning seat and is provided with a limiting hole corresponding to the first positioning hole. The cover body extends toward the axial direction and clamps the sealing ring in the constraint channel;

[0009] The reinforcing sleeve is provided with a groove on the side wall of the main body away from the positioning seat, the front end of the reinforcing sleeve is stuck in the groove, the reinforcing sleeve is provided with a through hole groove, the through hole groove is provided with a tightening sleeve, and the tightening sleeve is provided with a second positioning hole.

[0010] In the actual design, the cable passes through the limiting hole of the cover body and then extends into the first positioning hole, with the end of the cable extending out of the main body. The cover body is then installed on the positioning seat, and pressure is applied to the sealing ring to deform the sealing ring, while pressure is applied to the cable in the axial direction to deform the sealing ring, thereby achieving positioning and sealing of the positioning seat part.

[0011] Then the protruding part of the cable is extended into the second positioning hole of the tight sleeve, and then the reinforcing sleeve is placed on the outer wall of the tight sleeve, and the front end of the reinforcing sleeve is positioned with the groove of the rear wall of the main body, wherein the rear wall of the main body is also provided with a wire passing plate, which can be detachably installed between the wire passing plate and the main body to position the reinforcing sleeve.

[0012] Through double limiting, the cable can be stably set on the through-hole connector, which not only achieves the positioning of the cable but also ensures its waterproof effect, while effectively avoiding the problem of a single through-hole connector structure being broken.

[0030] The cover 2 is detachably mounted on the positioning seat 11 and is provided with a limiting hole 2a corresponding to the first positioning hole. The cover 2 extends toward the axial direction and clamps the sealing ring 53 in the constraint channel 11a.

[0031] The reinforcing sleeve 3 is provided with a groove 31 on the side wall of the main body 1 away from the positioning seat 11, and the front end of the reinforcing sleeve 3 is stuck in the groove 31. The reinforcing sleeve 3 is provided with a through hole groove 3a, and the through hole groove 3a is provided with a tightening sleeve 32, and the tightening sleeve 32 is provided with a second positioning hole 3b.

Then the cover 2 is installed on the positioning seat 11, and pressure is applied to the sealing ring 53 to deform the sealing ring 53, while applying pressure to the cable in the axial direction to deform the sealing ring 53, thereby achieving the positioning and sealing of the positioning seat 11.

[0033] Then the protruding part of the cable is extended into the second positioning hole 3b of the tight sleeve 32, and then the reinforcement sleeve 3 is placed on the outer wall of the tight sleeve 32, and the front end of the reinforcement sleeve 3 is positioned with the groove 31 on the rear wall of the main body 1, wherein the rear wall of the main body 1 is also provided with a wire passing plate 5, and the wire passing plate 5 and the main body 1 can be detachably installed to position the reinforcement sleeve 3.

[0034] Through double limiting, the cable can be stably set on the through-hole connector, which not only achieves the positioning of the cable but also ensures its waterproof effect, while effectively avoiding the problem of a single through-hole connector structure being broken.

[0035] Specifically, the outer peripheral wall of the positioning seat 11 is provided with a plurality of positioning ribs 11b, and the positioning ribs 11b are spaced apart along the outer periphery thereof. The provision of the positioning ribs 11b can improve the supporting strength of the positioning seat 11 and prevent the two sides of the positioning seat 11 from being broken.

[0036] In an embodiment of the present invention, the cover body 2 is provided with a stabilizing rib 11c extending in the direction of the positioning rib 11b, thereby ensuring an increased contact area between the positioning seat 11 and the cover body 2, while improving the stability of the limiting hole 2a, and effectively avoiding the problem of pressure fatigue of the cover body 2 caused by vibration.

[0037] Specifically, the limiting hole 2a has an annular rib extending toward the axial direction, which not only increases the thickness of the cover body 2 but also improves the restraint on the cable.

[0038] In the embodiment of the present invention, the cover 2 has at least two clamping parts 41 and a clamping hoop 42 extending toward the inner wall and outer wall of the positioning seat 11, respectively. The clamping part 41 extends into the positioning hole and abuts against the end of the sealing ring 53.

[0039] The clamp 42 is provided with a slot 4a, and the outer wall of the positioning seat 11 is provided with a buckle 4b that cooperates with the slot 4a. The cooperation between the clamp 42 and the clamping portion 41 can clamp the wall of the cover 2, ensuring the installation stability of the cover 2, while also applying pressure in the axial direction, improving the restraint stability of the cable.

[0040] Specifically, the clamp 42 is disposed between the two positioning ribs 11 b , and the two side walls of the clamp 42 abut against the side walls of the positioning rib 11 b , thereby improving the installation stability of the cover 2 .

[0042] Specifically, an annular boss 62 is extended toward the periphery from the front end of the reinforcement sleeve 3 , and an annular groove 61 matching with the annular boss 62 is provided on the rear wall of the main body 1 .

[0043] In an embodiment of the present utility model, the wire plate 5 is provided with a wire hole 5a, the inner diameter of the wire hole 5a is smaller than the inner diameter of the annular groove 61, thereby realizing the limiting of the reinforcing sleeve 3 by the wire plate 5, and at the same time, the annular boss 62 can also improve the function and load-bearing effect of the clamp 42.

[0044] Specifically, a gap 5b is provided between the wire hole 5a and the outer peripheral wall of the reinforcement sleeve 3, wherein the gap 5b is provided to allow slight shaking within the margin range, thereby reducing the risk of cracking the hole position to cope with more complex scenarios.
