Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness components, specifically, it relates to a high-sealing wiring harness connector. Background Technology

[0002] In traditional wire harness connector designs, conventional connectors typically rely solely on rubber sealing rings or glue filling to achieve dust and water resistance. After long-term use, these connectors are prone to aging and cracking, leading to seal failure. Ordinary connectors lack a uniformly distributed elastic clamping structure, resulting in gaps between the wire harness and the interface. Moisture and dust can easily seep in, creating a technical bottleneck in sealing performance and causing the connectors to fail easily in harsh environments. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a high-sealing wire harness connector. Through the nested structure of the first and second limiting rings and the even distribution of elastic pressure blocks, a tight fit is ensured at the connection point, effectively preventing the intrusion of external contaminants such as moisture and dust; through the snap-fit ​​design of the limiting groove and the limiting block, plus the external elastic fixing band, double limiting is provided to further prevent outward displacement.

[0004] To solve the above-mentioned technical problems, this utility model discloses a high-sealing wire harness connector, comprising: a first wire harness connector, a second wire harness connector inserted into the right side of the first wire harness connector, a semi-circular first limiting ring at the connection between the first wire harness connector and the second wire harness connector, a second limiting ring connected to the bottom of the first limiting ring, a limiting groove at the bottom of the first limiting ring, a limiting block corresponding to the limiting groove on the second limiting ring, evenly spaced elastic pressure blocks inside the first and second limiting rings, and corresponding locking grooves outside the first and second limiting rings, with elastic fixing bands inside the locking grooves.

[0005] According to one embodiment of the present invention, the first limiting ring and the second limiting ring are connected by a limiting groove and a limiting block.

[0006] According to one embodiment of the present invention, the number of the above-mentioned locking grooves is three sets.

[0007] According to one embodiment of the present invention, the number of the above-mentioned elastic pressure blocks is 18 sets.

[0008] Compared with the prior art, the present invention can achieve the following technical effects:

[0009] 1) The nested structure of the first and second limiting rings and the even distribution of elastic pressure blocks ensure a tight fit at the connection, effectively preventing the intrusion of external pollutants such as water vapor and dust; the double limiting design of the limiting groove and the buckle design of the limiting block, plus the external elastic fixing band, further prevents outward displacement.

[0010] Of course, any product implementing this utility model does not necessarily need to achieve all of the above technical effects at the same time. Attached Figure Description

[0017] Please refer to Figure 1 and Figure 2 , Figure 1 This is a front view of the high-sealing wire harness connector according to an embodiment of the present invention. Figure 2 This is an embodiment of the present utility model. Figure 1 A cross-sectional view of the first limiting ring 30 and the second limiting ring 40. As shown in the figure, a high-sealing wire harness connector includes: a first wire harness connector 10, a second wire harness connector 20 inserted into the right side of the first wire harness connector 10, a semi-circular first limiting ring 30 at the connection between the first wire harness connector 10 and the second wire harness connector 20, a second limiting ring 40 connected to the bottom of the first limiting ring 30, a limiting groove 50 at the bottom of the first limiting ring 30, and a limiting block 60 corresponding to the limiting groove 50 on the second limiting ring 40.

[0018] In this embodiment of the invention, the first wire harness connector 10 and the second wire harness connector 20 are connected by a plug-in joint for wire harness connection. A semi-circular first limiting ring 30 is provided at the connection point of the first wire harness connector 10 and the second wire harness connector 20. A second limiting ring 40 is provided at the bottom of the first limiting ring 30. The bottom of the first limiting ring 30 has evenly spaced limiting grooves 50. The second limiting ring 40 has a limiting block 60 corresponding to the limiting grooves 50. The first limiting ring 30 and the second limiting ring 40 are connected by a snap-fit ​​connection between the limiting grooves 50 and the limiting block 60, thereby protecting the connection point of the first wire harness connector 10 and the second wire harness connector 20.

[0019] Furthermore, the first limiting ring 30 and the second limiting ring 40 are provided with evenly spaced elastic pressure blocks 70, and the first limiting ring 30 and the second limiting ring 40 are provided with corresponding locking grooves 80, and the locking grooves 80 are provided with elastic fixing bands 90.

[0020] Specifically, the first limiting ring 30 and the second limiting ring 40 are provided with evenly spaced elastic pressure blocks 70, with 18 sets of elastic pressure blocks 70. This improves the sealing performance of the first limiting ring 30 and the second limiting ring 40 while preventing localized stress damage to the cable, achieving multi-level sealing. Finally, the first limiting ring 30 and the second limiting ring 40 are provided with corresponding locking grooves 80, and elastic fixing bands 90 are provided within the locking grooves 80. The three sets of locking grooves 80 provide multiple fixing options and can accommodate elastic fixing bands 90 of different diameters, enhancing environmental adaptability.

[0021] In summary, this utility model ensures a tight fit at the connection point through the nested structure of the first limiting ring 30 and the second limiting ring 40, as well as the even distribution of the elastic pressure block 70, effectively preventing the intrusion of external pollutants such as moisture and dust. The snap-fit ​​design of the limiting groove 50 and the limiting block 60, along with the external elastic fixing band 90, provides double limiting, further preventing outward displacement.
