Description

Technical Field

[0001] The present invention belongs to the field of connectors, and particularly relates to a connector for an automotive brake pump. Background Art

[0002] The connector for an automotive brake pump (brake caliper) is mainly used for connecting the circuit of the automotive braking system. The structure of the traditional connector for an automotive brake pump includes: a connector plug and a connector socket that are inserted and mated. Among them, the connector plug includes: a plug housing and male terminals provided in the plug housing; the connector socket includes: a socket housing and female terminals provided in the socket housing. After the connector plug is inserted into the connector socket, the male terminals will be inserted into the female terminals, thereby realizing the connection of the circuit. However, the main disadvantages are as follows: 1. The plug housing is usually connected to the hook on the outer wall of the socket housing by an elastic buckle on one side of the outer wall, which is used to lock the connector, and has the disadvantages of large volume, inconvenient use, and poor reliability; 2. There is no assisting mechanism for the insertion and extraction of the connector, resulting in difficult insertion and extraction; 3. The sealing ring is usually provided on the plug housing, which not only causes too much resistance to the insertion and extraction of the plug, but also cannot seal the gap between the terminal seat and the socket housing.

[0031] Refer to Figures 1-9As shown in the figure, the connector for an automotive brake pump of the present invention includes: a socket housing 1, a terminal block 2, a latch 3, and a plug housing 4. The socket housing 1 is provided with a plug insertion cavity 5 for inserting the plug housing 4, and a latch slot 6 and a latch positioning slot 7 are provided on one side of the socket housing 1, and the latch slot 6 communicates with the plug insertion cavity 5. The terminal block 2 is disposed at the center of the plug insertion cavity 5 of the socket housing 1 in an integrally formed or split manner, and a female terminal insertion cavity 49 is provided in the terminal block 2 for inserting female terminals. The latch 3 is detachably disposed in the latch slot 6 of the socket housing 1, and first sliding grooves 8 and elastic positioning buttons 9 are provided on both sides of the latch 3. The first sliding groove 8 includes a first inclined sliding groove 10 and a first horizontal sliding groove 11 that smoothly transitions with the first inclined sliding groove 10. A first positioning protrusion 12 and a second positioning protrusion 13 are provided at the front end of the inner wall of the elastic positioning button 9, and a positioning opening 14 that cooperates with the latch positioning slot 7 is formed between the first positioning protrusion 12 and the second positioning protrusion 13. When the latch 3 is pulled out in place, the positioning opening 14 is snapped into the latch positioning slot 7 to fix the latch 3 and prevent it from falling off. An unlocking inclined surface 15 is provided at the upper end of the first positioning protrusion 12, and an unlocking clearance 16 is left between the elastic positioning button 9 and the side wall of the latch 3. The plug housing 4 is detachably disposed in the plug insertion cavity 5 of the socket housing 1, and a first slider 17 adapted to the first sliding groove 8 and an unlocking portion 18 that presses against the unlocking inclined surface 15 are provided on the side wall of the plug housing 4. First slider insertion ports 19 that smoothly transition with the first sliding groove 8 are provided at the upper ends of both sides of the latch 3. When the plug housing 4 is inserted into the socket housing 1 and the first slider 17 slides to the bottom of the first slider insertion port 19, the unlocking portion 18 presses against the unlocking inclined surface 15, causing the positioning opening 14 to move away from the latch positioning slot 7 to automatically unlock the latch 3, ensuring that the plug housing 4 can continue to be inserted normally. At this time, the plug housing 4 can also be driven to be inserted downward by pushing the latch 3 inward and with the cooperation of the first inclined sliding groove 10 and the first slider 17 to provide assistance. When the first slider 17 slides into the end of the first horizontal sliding groove 11, the latch 3 completes the locking of the plug housing 4. When the plug housing 4 needs to be pulled out, the latch 3 needs to be pulled out first, and during the pulling out process, with the cooperation of the first inclined sliding groove 10 and the first slider 17, the plug housing 4 can be driven to be pulled out upward, which also provides assistance.

[0032] Preferably, second sliding grooves 20 are provided on both sides of the latch 3 corresponding to the lower front of the first sliding groove 8. The second sliding grooves 20 include second inclined sliding grooves 21 and second horizontal sliding grooves 22 that are smoothly transitioned with the second inclined sliding grooves 21. Second sliding blocks 23 adapted to the second sliding grooves 20 are provided on the side wall of the plug housing 4. Second sliding block insertion openings 24 that are smoothly transitioned with the second sliding grooves 20 are provided at the front ends of both sides of the latch 3. Through the cooperation of two sliding grooves and two sliding blocks, the plug housing 4 can be locked more stably and driven to be inserted and pulled out.

[0033] Preferably, the terminal block 2 is connected to the positioning groove 27 and the hanging platform 28 at the bottom of the socket housing 1 through the positioning flange 25 and the barb 26 at the bottom respectively. To achieve the detachable assembly between the terminal block 2 and the socket housing 1, so as to facilitate the assembly of the female terminal, the terminal anti-retreat clip 30 and the sealing ring 29. A sealing ring 29 is provided at the bottom of the terminal block 2. After the barb 26 is connected to the hanging platform 28, the bottom of the sealing ring 29 is extruded at the connection gap between the positioning flange 25 and the socket housing 1, and the side surface is sealed to the inner wall of the plug housing 4. Thus, the overall sealing effect of the connector is achieved. And under the elastic force of the sealing ring 29, the connection between the terminal block 2 and the socket housing 1 is more stable and reliable.

[0034] Preferably, a pluggable terminal anti-retreat clip 30 is provided on one side of the terminal block 2. The terminal anti-retreat clip 30 includes a U-shaped bayonet 31 inserted into the terminal block 2 and a U-shaped side wall 32. A retreat prevention table surface 33 extending into the female terminal insertion cavity 49 is provided in the U-shaped bayonet 31. A rib 34 connected to the terminal block 2 is provided on the U-shaped side wall 32. After the female terminal is inserted into the female terminal insertion cavity 49, the terminal anti-retreat clip 30 is inserted so that its retreat prevention table surface 33 abuts against the rear of the female terminal to play a role in preventing the retreat of the female terminal. And after the terminal anti-retreat clip 30 is inserted, it forms an integral body with the terminal block 2, which not only does not occupy space and has good aesthetics, but also does not have the problem of the terminal anti-retreat clip falling off because it is arranged in the plug insertion cavity 5 of the socket housing 1.

[0035] Preferably, positioning convex points 35 are provided on the side surface of the latch 3, and positioning holes 36 cooperating with the positioning convex points 35 are provided on the side surface of the socket housing 1. After the latch 3 is inserted in place, the positioning convex points 35 are embedded in the positioning holes 36 to play a role in fixing the latch 3 and preventing it from falling off.

[0036] Preferably, a boosting button mounting opening 37 is provided at the bottom of the latch 3.

A power inclined surface 40 and a labor-saving lever portion 50 are provided at the bottom of the boosting unlocking button 38. A resistance inclined surface 41 cooperating with the power inclined surface 40 is provided on the socket housing 1. Since the resistance is the greatest at the starting position of the connector, and with the positioning of the positioning bumps 35 and the positioning holes 36, it is relatively difficult to directly pull out the latch 3. However, for the above-described boosting unlocking button 38 structure, by using the lever principle, when unlocking, by pushing the labor-saving lever portion 50 upward and under the interaction of the power inclined surface 40 and the resistance inclined surface 41, the latch 3 and the plug housing 4 can be easily pulled out.

[0037] Preferably, an insert injection molding portion 42 is integrally formed at the bottom of the socket housing 1, and a runner bar 43 is provided on the insert injection molding portion 42. Through the insert injection molding portion 42, the socket housing 1 can be insert injection molded onto the cable of the automotive brake pump, making their connection more reliable.

[0038] Preferably, positioning grooves 44 adapted to the first positioning bumps 12 and the second positioning bumps 13 are provided on both sides of the plug housing 4. An inclined first guiding surface 45 is provided at the rear end of the second positioning bump 13, and a second guiding surface 46 is provided at the rear end of the positioning groove 44. After the latch 3 is inserted in place, the first positioning bumps 12 and the second positioning bumps 13 are positioned in the positioning grooves 44 to further fix the latch 3. At the same time, through the cooperation of the first guiding surface 45 and the second guiding surface 46, the smooth pulling out of the latch 3 can be ensured.

[0039] Preferably, a first slider positioning groove 47 and a second slider positioning groove 48 are provided at the upper end of the socket housing 1. To ensure the precise insertion of the first slider 17 and the second slider 23.
