Description

Technical Field

[0001] This utility model relates to the field of wire harness connectors, specifically a high-sealing standardized connector for modular wire harnesses. Technical Background

[0002] In the automotive, aerospace, and industrial automation fields, modular wiring harness systems need to connect numerous electronic and electrical components. For example, high and low voltage wiring harnesses in automobiles are subject to vibration, bumps, and various complex environments during vehicle operation. This requires wiring harness connectors to have high sealing performance to prevent the intrusion of moisture, dust, etc., and to ensure stable electrical performance.

[0003] Traditional wire harness connectors have some problems. For example, the process of crimping the terminals and cables and then inserting them into the connector is difficult and can easily lead to problems such as damage to the wire crimping points and poor contact. In addition, the connector connection method is relatively simple, usually only connected by threads or bolts. The sealing performance of the connector after connection is weak. Long-term vibration and thermal expansion and contraction may cause the connection to loosen and allow water and dust to enter. Utility Model Content

[0004] (I) Technical Issues

[0005] The technical problem to be solved by this utility model is that the insertion operation of wire harnesses is difficult in the prior art, the connection method is simple, and the sealing of the connection is weak, making it easy for water and dust to enter.

[0006] (II) Technical Solution

[0007] To address the above technical challenges, this solution provides a high-sealing standardized connector for modular wire harnesses, achieved through the following technical means:

[0008] A high-sealing standardized connector for modular wire harnesses includes a female connector body and a male connector body. A locking nut is threadedly connected to one side of the female connector body, and a wire harness fixing ring is detachably provided on the same side. A compression ring is provided on a threaded post on one side of the female connector body, and a sealing ring is sleeved on the outside of the wire harness fixing ring. It also includes a positioning device between the locking nut and the male connector body.

[0009] The positioning device includes a locking platform located on the locking nut, and a locking plate located on one side of the male body that cooperates with the locking platform.

[0010] As an improvement, the wire harness fixing ring is provided with several wire-passing holes, and a rectangular through groove communicating with the wire-passing holes is opened on the outer side of the wire harness fixing ring.

[0011] As an improvement, the sealing ring tightly wraps around the wire harness fixing ring, and both are placed inside the compression ring and locked by the locking nut pressing the compression ring.

[0012] As an improvement, the male connector body has several conductive posts corresponding to the wire holes. The conductive posts are inserted into the wire holes, and the locking nuts on the male connector body and the female connector body are connected by threads.

[0013] As an improvement, a rectangular groove is provided on the locking plate, and a slot that engages with the rectangular groove is provided on one side of the locking platform.

[0014] As an improvement, a sealing gasket is also provided at the connection between the male head body and the locking nut.

[0015] (III) Technical Effects

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. A rectangular through groove is provided on the wire harness fixing ring, which corresponds to and connects to the wire hole. The wire harness can be quickly passed into the wire hole through the rectangular through groove. In addition, a sealing ring is tightly wrapped on the outside of the wire harness fixing ring to enhance the sealing performance.

[0018] 2. A compression ring is provided on the threaded post on one side of the female head body. The wire harness fixing ring, which is wrapped by the sealing ring, is inserted into the compression ring and locked by the locking nut. This makes the stability stronger and reduces the possibility of the wire harness falling off and loosening.

[0019] 3. The male connector body and the locking nut are also equipped with positioning devices, and a sealing gasket is provided at the connection. The rectangular groove on the locking plate engages with the slot on the locking platform to make the joint more stable and less prone to loosening. Attached Figure Description

[0028] A high-sealing standardized connector for modular wire harnesses, such as Figure 1 , Figure 2 As shown, it includes:

[0029] The device comprises a female connector body 1 and a male connector body 2. A locking nut 4 is threaded onto one side of the female connector body 1, and a wire harness retaining ring 5 is detachably mounted on the same side. The wire harness retaining ring 5 has several through holes 6, and rectangular through slots 8 communicating with the through holes 6 are provided on the outer side of each wire harness retaining ring 5. The wire harness can be quickly inserted into the through holes 6 through the rectangular through slots 8. The locking nut 4 is used to lock the wire harness retaining ring 5. A compression ring 3 is provided on a threaded post on one side of the female connector body 1, and a sealing ring 7 is fitted around the outer side of the wire harness retaining ring 5. The sealing ring 7 tightly wraps around the wire harness retaining ring 5. Both are placed inside the compression ring 3 and locked by the locking nut 4 pressing the compression ring 3, resulting in greater stability and reducing the possibility of the wire harness falling off or loosening. The device also includes a positioning device between the locking nut 4 and the male connector body 2.

[0030] like Figure 3 , Figure 4As shown, the male connector body 2 has several conductive posts 13 corresponding to the wire holes 6. The conductive posts 13 are inserted into the wire holes 6. The male connector body 2 and the locking nut 4 on the female connector body 1 are connected by threads. A sealing gasket 11 is provided at the connection to enhance the sealing between the connectors. The positioning device includes a locking platform 10 located on the locking nut 4 and a locking plate 9 located on one side of the male connector body 2 that cooperates with the locking platform 10. A rectangular groove 14 is provided on the locking plate 9. A slot 12 that engages with the rectangular groove 14 is provided on one side of the locking platform 10. The rectangular groove 14 and the slot 12 engage and position the connector, making it more stable and less prone to loosening.

[0031] In the specific implementation of this embodiment:

[0032] In use, the wire harness is quickly inserted through the rectangular slot 8 on the wire harness fixing ring 5 into the wire hole 6. The sealing ring 7 is fitted onto the wire harness fixing ring 5, and then the sealing ring 7 is inserted into the compression ring 3. The locking nut 4 is threaded through the wire harness fixing ring 5 and the sealing sleeve 7 and threaded onto the threaded post on one side of the female head body 1. The locking nut 4 presses against the compression ring 3, thereby locking the wire harness fixing ring 5 and the sealing sleeve 7. The male head body 2 is then mated with the locking nut 4 on the female head body 1 and rotated to form a threaded connection, so that the conductive post 13 in the male head body 2 is inserted into the wire hole 6 and conducts electricity with the wire harness in the wire hole 6. After rotating to the position, the locking plate 9 on the male head body 2 mates with the locking platform 10 on the locking nut 4. The rectangular slot 14 on the locking plate 9 engages with the slot 12 on the locking platform 10 for positioning, and the connector connection is completed.
