Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a waterproof connector for wire harnesses. Background Technology

[0002] Wire harness connectors, also known as wire harness plugs, are a type of terminal block consisting of a plug and a socket. They are primarily used for wire harness connections in automotive circuits, serving as electrical relays between electrical devices. They are also used in instruments, office equipment, and commercial machinery. They employ a locking device to ensure connection stability and prevent vibration-induced detachment; the locking device must be released before disassembly.

[0003] This product utilizes a structural design incorporating wiring rings, flexible wire clips, and segmented sheaths to achieve orderly wire arrangement and route adjustment, improving line maintenance efficiency. Some models are equipped with sealing gaskets, dust rings, and drying pads to enhance dust and water resistance. Terminal connections employ cold pressing (open / closed) or hot pressing (ultrasonic welding) processes, combined with positioning grooves and bosses to ensure conductivity accuracy. Domestic manufacturers leverage mold development and plastic molding technology to achieve cost control advantages.

[0004] Traditional wire harness connectors can only make simple connections between wire harnesses, but they cannot guarantee the waterproofness of the connection points. This allows water to easily enter the connection points during use, affecting the performance and lifespan of the wire harness. Utility Model Content

[0005] The main purpose of this utility model is to provide a waterproof connector for wire harnesses, which can effectively solve the problem of not being able to guarantee the waterproofness of the connector.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A waterproof connector for wire harnesses includes an outer sheath, a bearing mechanism fixedly connected to the lower end of the outer surface of the outer sheath, a sealing mechanism movably connected to the upper side inside the bearing mechanism, a connecting component threadedly connected inside the bearing mechanism, a positioning mechanism fixedly connected to the lower side outside the connecting component, and waterproof mechanisms fixedly connected to both the lower side outside the positioning mechanism and the upper end of the outer surface of the outer sheath.

[0007] Preferably, the bearing mechanism includes a bearing housing, the top wall of the inner cavity of the bearing housing is provided with an annular groove, and a plurality of arc-shaped plates are fixedly connected in an annular array to the lower end of the outer surface of the bearing housing, and a plurality of arc-shaped clamping strips are fixedly connected at intervals to the lower part of the inner surface of the plurality of arc-shaped plates.

[0008] Preferably, the sealing mechanism includes a clamping ring, and a sealing gasket is fixedly connected to the lower end of the outer surface of the clamping ring, and the clamping ring is movably connected to the inner cavity of the annular groove.

[0009] Preferably, the connecting component includes a connecting sleeve, and the outer surface of the connecting sleeve is provided with external threads.

[0010] Preferably, the positioning mechanism includes a second bearing sleeve, the lower part of the outer surface of the second bearing sleeve is provided with a plurality of arc-shaped positioning grooves in a circular array, the left and right parts of the plurality of arc-shaped positioning grooves are provided with chamfers, and the upper end of the outer surface of the second bearing sleeve is fixedly connected to the lower end of the outer surface of the connecting sleeve.

[0011] Preferably, the waterproofing mechanism includes an annular base plate, the upper surface of which is provided with a corrugated constricted rubber, and the upper surface of which is provided with an annular rubber ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses a supporting mechanism to support the sealing mechanism, and the sealing mechanism to seal the connection between the supporting mechanism and the positioning mechanism, thus improving the practicality of the device. The connecting component connects the supporting mechanism and the positioning mechanism, and the positioning mechanism allows for easy locking of the position of the supporting mechanism. Furthermore, the waterproof mechanism allows for easy wrapping of the ends of the two interlocking wire harnesses for waterproofing, thus improving the practicality and versatility of the device.

[0013] The present invention rotates the bearing sleeve one so that the upper part of the inner cavity of the bearing sleeve one is threaded with the external thread, thereby enabling the bearing sleeve one to slide along the outer surface of the connecting sleeve until several arc-shaped clamping strips are clamped in the inner cavity of the corresponding arc-shaped positioning groove, thereby enabling the bearing sleeve one to be stably clamped to the outside of the bearing sleeve two, avoiding the phenomenon of the bearing sleeve one and the bearing sleeve two falling off, and improving the practicality and universality of the device.

A connecting component 4 is threadedly connected to the inner side of the bearing mechanism 2, which can connect the bearing mechanism 2 and the positioning mechanism 5. The positioning mechanism 5 is fixedly connected to the lower side of the outer side of the connecting component 4, which can lock the position of the bearing mechanism 2. A waterproof mechanism 6 is fixedly connected to the lower side of the outer side of the positioning mechanism 5 and the upper end of the outer surface of the outer sheath 1, which can wrap the tail ends of the two interlocking wire harnesses for waterproofing.

[0018] To achieve the purpose of bearing the load on the sealing mechanism 3, see [reference] Figure 2 The bearing mechanism 2 includes a bearing housing 21. The top wall of the inner cavity of the bearing housing 21 is provided with an annular groove 22, which can accommodate the clamping ring 31. Several arc-shaped plates 23 are fixedly connected in an annular array at the lower end of the outer surface of the bearing housing 21. Several arc-shaped clamping strips 24 are fixedly connected at intervals on the lower part of the inner surface of the arc-shaped plates 23, which can cooperate with the corresponding arc-shaped positioning grooves 52 to lock the position of the bearing housing 21.

[0019] To achieve the purpose of sealing the connection between the bearing mechanism 2 and the positioning mechanism 5, refer to... Figure 3 The sealing mechanism 3 includes a clamping ring 31, and a sealing gasket 32 ​​is fixedly connected to the lower end of the outer surface of the clamping ring 31. This can seal the connection between the top wall of the inner cavity of the bearing housing 1 21 and the upper end of the outer surface of the bearing housing 2 51. The clamping ring 31 is movably connected to the inner cavity of the annular groove 22.

[0020] To achieve the purpose of connecting the bearing mechanism 2 and the positioning mechanism 5, refer to... Figure 4The connecting component 4 includes a connecting sleeve 41. The outer surface of the connecting sleeve 41 is provided with an external thread 42, which can realize the function of installing the second bearing sleeve 51 in the lower part of the inner cavity of the first bearing sleeve 21 by means of threaded transmission with the upper part of the inner cavity of the first bearing sleeve 21.

[0021] To facilitate locking the position of the bearing mechanism 2, please refer to... Figure 4 The positioning mechanism 5 includes a second bearing sleeve 51. The lower part of the outer surface of the second bearing sleeve 51 has several arc-shaped positioning grooves 52 arranged in a ring array, which can accommodate the corresponding arc-shaped clamping strips 24.

The upper part of the outer surface of the annular base plate 61 is provided with a corrugated shrink rubber 62, which can wrap and waterproof the end of the wire harness. The upper part of the outer surface of the corrugated shrink rubber 62 is provided with an annular rubber ring 63, which can tighten and wrap the end of the wire harness through its own elasticity, thereby preventing external water from entering the inner cavity of the outer sheath 1 or the bearing shell 2 51.

[0023] The working principle of this utility model is as follows: Two compatible wire harnesses are inserted into the inner cavities of the outer sheath 1 and the second bearing sleeve 51, respectively. Then, the two wire harnesses are interlocked. At this time, the first bearing sleeve 21 is threaded along the outer surface of the connecting sleeve 41 and the external thread 42, so that the first bearing sleeve 21 can slowly rotate along the outer surface of the connecting sleeve 41 until several arc-shaped clamping strips 24 are clamped in the inner cavity of the corresponding arc-shaped positioning grooves 52. During this process, the upper end of the outer surface of the second bearing sleeve 51 will squeeze the sealing gasket 32, so that the clamping ring 31 drives the sealing gasket 32 ​​to clamp on the top wall of the inner cavity of the first bearing sleeve 21, thereby ensuring the sealing of the inner cavity of the first bearing sleeve 21. At the same time, the tail end of the wire harness can be wrapped and tightened by two sets of elastic corrugated shrink rubber 62 and annular rubber ring 63, thereby effectively preventing external water from entering the inner cavity of the first bearing sleeve 21 and the second bearing sleeve 51.
