Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a passenger vehicle wiring harness connector. Background Technology

[0002] A wire harness connector is a type of terminal, also known as a plug or socket. In the electrical circuits of new energy passenger vehicles, connectors are generally used to connect wire harnesses to each other and to electrical components. As a relay station for the wire harness, the connector is an indispensable part of ensuring the stable operation of the vehicle.

[0003] Among the commonly used wire harness connectors, although various types of connectors can achieve the connection function, due to the small size of the wire harness connector joints, the connectors in the existing technology often fall off during use because the connection is not secure enough, which affects the use.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model provides a technical solution:

[0028] A cleverly designed wiring harness connector for passenger vehicles enables a secure connection between the male and female connectors, effectively preventing them from coming loose.

[0029] The passenger vehicle wiring harness connector includes a female connector 1 and a male connector 2 that can be plugged into each other. One end of the male connector 2 is connected to the wiring harness body 18 for transmitting electrical signals. The male connector 2 consists of a fixing part 4 and a housing 3 connected from top to bottom. Both the fixing part 4 and the housing 3 are made of insulating and flame-retardant materials to ensure safe use.

[0030] An adjusting cover 5 is rotatably mounted on the outer wall of the fixing part 4 via a bearing. The adjusting cover 5 can rotate around the fixing part 4. The outer wall of the fixing part 4 has symmetrically arranged clips and holes 6. The outer wall of the male head 2 has symmetrically arranged clips 8. The clips 8 are made of elastic material and their shape matches the clips and holes 6, allowing them to engage with the clips and holes 6 for initial fixation. Friction-enhancing plates made of rubber are provided on both the upper and lower sides of the clips 8 to increase the friction between the clips 8 and related components, improving the fixing effect. The upper part has evenly distributed sliding grooves 9. The inner wall of the adjusting cover 5 is symmetrically provided with fixing plates 14. The fixing plates 14 are designed as fan-shaped structures and are inserted into the sliding grooves 9 and slidably assembled. When the adjusting cover 5 is rotated, the fixing plates 14 can slide along the sliding grooves 9. The outer wall of the fixing part 4 is symmetrically provided with mounting grooves 7. The mounting grooves 10 are fixedly installed in the mounting grooves 7. The outer wall of the guide rods 10 is inserted into and slidably assembled with a lever 12. The lever 12 is slidably installed in the mounting grooves 7 and can slide along the guide rods 10 in the mounting grooves 7. A return spring 11 is sleeved on the guide rod 10. The return spring 11 abuts against the inner wall of the lever 12 and the mounting groove 7 respectively, and can provide a return force for the lever 12. A plug 13 is provided on one side of the lever 12. The plug 13 is inserted into the fixing part 4 and slidably assembled. The male head 2 has symmetrical slots 15 on its outer wall. The plug 13 is inserted into the slot 15 and slidably assembled. The movement of the male head 2 can be further restricted by the cooperation between the plug 13 and the slot 15. The adjustment cover 5 has a first alignment hole 16 and a second alignment hole 17 facing each other on its outer wall. The first alignment hole 16 and the second alignment hole 17 correspond to the locking hole 6 and the mounting groove 7 respectively. During the rotation of the adjustment cover 5, it can be aligned or misaligned with the locking hole 6 and the mounting groove 7.

[0031] In use, first move the lever 12 to one side. The lever 12 slides along the guide rod 10 in the mounting groove 7, compressing the return spring 11 and causing the insert 13 to retract into the fixing part 4. Hold the male head 2, align it with the female head 1, and insert it. When the male head 2 is fully inserted into the female head 1, the locking block 8 engages with the locking hole 6 in the fixing part 4, achieving initial connection. At this time, release the force on the lever 12, and the return spring 11 returns to its deformation, pushing the lever 12 to slide in the opposite direction. The lever 12 drives the insert 13 to insert into the slot 15 on the outer wall of the male head 2, completing the initial limiting of the male head 2 and preventing the male head 2 from moving left or right. Then, twist the adjusting cover 5. The adjusting cover 5 rotates around the fixing part 4, and the fixing plate 14 on its inner wall slides along the slide groove 9. Finally, located above and below the locking block 8, it cooperates with the locking hole 6 to limit the locking block 8, preventing the locking block 8 from disengaging from the locking hole 6, thereby restricting the up and down movement of the male head 2. After the adjusting cover 5 is rotated, the first alignment hole 16 and the second alignment hole 17 on it also rotate, forming a misalignment with the locking hole 6 and the mounting groove 7, thereby completely sealing the fixing part 4 and preventing external dust and impurities from entering and affecting the connection effect. When it is necessary to separate the male head 2 and the female head 1, twist the adjusting cover 5 in the opposite direction to make the fixing plate 14 leave the area above and below the locking block 8. The first alignment hole 16 and the second alignment hole 17 are respectively aligned with the locking hole 6 and the mounting groove 7. Then, move the lever 12 to make the insert 13 disengage from the slot 15. Finally, pull out the male head 2.

[0032] After the male connector 2 is inserted into the female connector 1, the locking block 8 engages with the locking hole 6 to achieve a preliminary connection. Under the action of the return spring 11, the push block 12 drives the insertion block 13 to insert into the slot 15, restricting the left and right movement of the male connector 2. Twisting the adjusting cover 5 makes the fixing plate 14 located above and below the locking block 8, which cooperates with the locking hole 6 to restrict the locking block 8 from disengaging and prevent the male connector 2 from moving up and down. At the same time, the adjusting cover 5 closes the fixing part 4 to avoid external interference, thus achieving a stable connection between the male connector 2 and the female connector 1. The operation is simple and can quickly complete the connection and separation.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
