Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an in-vehicle grade connector applied to a rotating speed regulating motor of an automotive headlight. Background Art

[0002] In the prior art, the connector applied to the rotating speed regulating motor of an automotive headlight often has an integrated fully enclosed structure. However, some drawbacks that cannot be ignored have gradually emerged in practical applications. The most prominent one is the problems presented in terms of volume, thickness, and weight. Its relatively large volume may limit the layout of other components inside the headlight module, affecting the heat dissipation design of the headlight and the installation space of the light adjustment mechanism. In terms of thickness, an overly thick connector may cause an increase in the overall thickness of the headlight module. In the limited space of the vehicle front face, it may affect the matching degree with other components, and even may require additional adjustments to the vehicle body structure. In terms of weight, a heavier connector will increase the load of the rotating speed regulating motor of the headlight, affecting the flexibility of its rotation and the accuracy of speed regulation, and further affecting the timeliness and accuracy of the adjustment of the headlight irradiation angle, posing a safety hazard to the driver during night driving.

The first buckle 23 and the first limiting rib 21 are arranged in parallel and there is an opening for accommodating the first guiding rib 11 therebetween. The first buckle 23 is used for snap connection with the second buckle 13. The first limiting rib 21 is accommodated between the first guiding rib 11 and the second guiding rib 12 and is used to limit the vertical movement of the male housing 10.

[0033] The male housing 10 is a hollow cuboid structure including an upper wall, a lower wall, a left wall, a right wall and a rear wall. The length of the lower wall is less than that of the upper wall. On the outer surfaces of the rear ends of the left wall and the right wall of the male housing 10, a first guiding rib 11 and a second guiding rib 12 parallel to each other are provided. On the upper surface of the first guiding rib 11, a second buckle 13 is provided. The first guiding rib 11 extends forward to form a buckling portion 14. On the front end of the outer surface of the upper wall of the male housing 10, a first pinching portion 16 is provided.

On the rear wall of the male housing 10, a plurality of insertion channels 113 for inserting the male terminals 40 are provided.

[0034] The positioning auxiliary part 30 is a cuboid structure with a "U"-shaped cross-section. Third fastening parts 32 are arranged on the inner surfaces of both side walls of the positioning auxiliary part 30. The third fastening parts 32 are arranged with inclined surfaces for facilitating the fastening of the fastening part 14 of the male housing 10. A plurality of mutually parallel reinforcing ribs 31 are arranged on the inner surface of the bottom wall of the positioning auxiliary part 30 in the front-back direction. The plurality of reinforcing ribs 31 divide the positioning auxiliary part 30 into an isolation rib installation groove and a female terminal accommodation groove which are arranged at intervals. The isolation rib installation groove is used for clamping the isolation rib 17 on the male housing. An insertion groove 33 adapted to the protrusion 111 of the male housing 10 is arranged on the isolation rib installation groove. The protrusion 111 and the insertion groove 33 cooperate to improve the stability of the insertion of the positioning auxiliary part 30 and the male housing 10. The female terminal accommodation groove is used for accommodating the female terminal 50 and the wire. The existence of the reinforcing ribs 31 can press the female terminal 50 and the wire in the vertical direction to improve the stability of the female terminal 50 and the wire. A limiting part 34 is arranged at the rear end of each female terminal accommodation groove. The limiting part 34 abuts against the first abutting part 53 of the female terminal 50 for restricting the movement of the female terminal 50 in the direction of being inserted into the male housing 10. A second pinching part 35 is further arranged at the front end of the outer surface of the lower wall of the positioning auxiliary part 30. The second pinching part 35 cooperates with the first pinching part 16 for pinching.

[0035] The female terminal 50 includes a wire insertion part and a plug-in part connected to the wire insertion part. The wire insertion part is used for accommodating the wire end to form an electrical connection between the wire end and the female terminal 50. The plug-in part is used for plugging with the male terminal 40 to form an electrical connection between the male terminal 40 and the female terminal 50. The cross-section of the wire insertion part is arched. A first clamping arm 51, a second clamping arm 52 and a first abutting part 53 are sequentially arranged at the front end of the wire insertion part towards the rear end. The first clamping arm 51 is used for tightly wrapping the insulating layer of the wire end. The second clamping arm 52 is used for tightly wrapping the wire of the wire end to realize the electrical connection between the wire end and the female terminal 50. A plug-in head 54 is arranged at the front end of the plug-in part. The cross-section of the plug-in head 54 is "convex"-shaped to facilitate the vertical limiting of the plug-in head 54 by the third limiting rib 18 and avoid the shaking or tilting of the female terminal 50. A clamping part 55 for clamping the male terminal 40 is arranged on the inner surface of the side wall of the plug-in head. A second abutting part 56 for snap-connecting with the elastic limiting part 15 is further arranged on the upper surface of the plug-in head. The vertical limiting of the plug-in head 54 by the third limiting rib 18 makes the snap-connection between the elastic limiting part 15 and the second abutting part 56 more stable.

[0036] The male terminal 40 includes an insertion section and a welding section. The insertion section and the welding section are arranged in an "L" shape. The insertion section passes through the male terminal insertion hole on the rear wall of the female housing 20 and the insertion channel 113 on the rear wall of the male housing to be electrically connected to the corresponding female terminal 50. A bending part 41 is arranged on the welding section. The bending part 41 is used for adjusting the insertion direction of the male terminal 40 on the one hand and increasing the electrical contact points of the male terminal 40 with other components during welding on the other hand.

[0037] When the automotive-grade connector is installed, first, the female terminal 50 with the wire end already connected to the wire insertion part is installed in the female terminal accommodation groove of the positioning auxiliary part 30, so that the first abutting part 53 abuts against the limiting part 34; secondly, the isolation rib installation groove of the positioning auxiliary part 30 is aligned with the isolation rib 17 of the male housing 10 one by one for insertion until the positioning auxiliary part 30 and the male housing 10 form a stable connection through the snap connection of the third snap part 32 and the snap connection part 14. At this time, the protrusion 111 is accommodated in the insertion slot 33, and the second abutting part 56 and the elastic limiting part 15 are snap-connected; after that, hold the second holding part 35 and the first holding part 16, and align the second limiting rib 22 with the limiting slot 19 for insertion until a stable snap connection is formed between the first snap part 23 and the second snap part 13. At this time, the rear end of the positioning auxiliary part 30 abuts against the front end of the female housing 20, and the lower wall of the positioning auxiliary part 30 and the lower wall of the female housing 20 form the lower wall of the automotive-grade connector; finally, the insertion section of the male terminal 40 is inserted into the male terminal insertion hole and the insertion channel 113 to be electrically connected to the corresponding female terminal 50.
