[0002] The ABS sensor monitors the vehicle's braking status by sensing the rotation speed of the wheel. It is mainly composed of an inductive sensor or a Hall sensor, which works with the gear ring that rotates synchronously with the wheel to output a set of quasi-sinusoidal AC signals related to the wheel speed. These signals are then transmitted to the ABS electronic control unit (ECU) to achieve real-time monitoring of the wheel speed. The corresponding connector is required when connecting the ABS sensor.

[0031] See also Figure 1-4 As shown, an ABS sensor line connector, the ABS sensor line connector includes:

[0032] A wiring terminal 1, wherein a rubber-coated shell 2 is fixedly provided on the outer surface of the wiring terminal 1, and a connecting cable 3 is fixedly connected to the bottom end of the rubber-coated shell 2, and the connecting cable 3 is electrically connected to the wiring terminal 1;

[0033] A locking and fixing structure, the locking and fixing structure comprises a fixing frame 4, a limiting protrusion 5 and a self-locking unit, and the self-locking unit can automatically lock and fix the limiting protrusion 5 after the limiting protrusion 5 is inserted into the fixing frame 4;

[0034] A waterproof unit is provided between the fixing frame 4 and the limiting protrusion 5 , and the waterproof unit can provide a sealed and waterproof function for the connection terminal 1 .

[0035] Through the above technical scheme, it has good waterproof performance. The rubber-coated shell 2 and the terminal 1 are molded by high-pressure injection molding, and the waterproof performance is high. In order to solve the problem that the ordinary sensor line connection is easy to loose in the prior art, a locking and fixing structure is designed. The terminal 1 can be fixed by the locking and fixing structure to prevent loosening. At the same time, it is further sealed and waterproof to prevent water from entering the terminal 1 and causing a short circuit, which is suitable for popularization and use;

[0036] The rubber-coated shell 2 is fixedly arranged on the terminal 1 by high-pressure injection molding. Through the technical solution, during processing, the terminal is directly inserted into the injection mold and formed by high-pressure injection molding, and the waterproof performance is relatively excellent. Compared with the conventional connector in the prior art, which is assembled by a sheath and a crimping terminal, the waterproof performance is poor, and the production consumes more manpower and the production efficiency is low. The present application is formed by high-pressure injection molding, and the waterproof performance is high, and there is no terminal retreat phenomenon;

[0037] The limiting protrusion 5 is fixedly arranged at the connection terminal 1, and the limiting protrusion 5 is slidably plugged into the fixing frame 4. Before use, the fixing frame 4 is fixed to the socket connected to the connection terminal 1, and when the connection terminal 1 is inserted into the socket for connection, the limiting protrusion 5 is inserted into the inside of the fixing frame 4 at the same time;

[0038] The locking and fixing structure includes a limit block 7, a locking tenon 8, an L-shaped guide rod 10, a reset spring 11 and a connecting disc 12. The interior of the fixed frame 4 is provided with an inner cavity, and the limit block 7 is slidably connected in the inner cavity of the fixed frame 4. The side wall of the limit block 7 is fixedly provided with a locking tenon 8, and the bottom surface of the locking tenon 8 is an inclined surface; the side wall of the limit protrusion 5 is provided with a slot 9.

[0039] One end of an L-shaped guide rod 10 is fixedly connected to a side wall of one side of the limit block 7, the other end of the L-shaped guide rod 10 passes through the fixed frame 4 and is slidably matched with the fixed frame 4, and a connecting disc 12 is fixedly connected to one end of the L-shaped guide rod 10;

[0040] One end of a return spring 11 is fixedly connected to one side of the L-shaped guide rod 10, and the other end of the return spring 11 is fixedly connected to the inner wall of the fixed frame 4. Through the present technical solution, when the limiting protrusion 5 is inserted into the interior of the fixed frame 4, the limiting protrusion 5 will contact the bottom inclined surface of the locking tenon 8 and squeeze the locking tenon 8, so that the locking tenon 8 moves outward, and when the slot 9 moves to a position flush with the locking tenon 8, the limiting block 7 is automatically pushed to move through the rebound effect of the return spring 11, thereby driving the locking tenon 8 to move, so that the locking tenon 8 is inserted into the slot 9, thereby locking and fixing the limiting protrusion 5.

[0041] The waterproof unit includes a rubber ring 6, a cylinder 13, a movable piston 14, a connecting rod 15 and a connecting pipe 16. The rubber ring 6 is fixedly arranged at the gap between the fixed frame 4 and the limiting protrusion 5. An inner cavity is arranged inside the rubber ring 6, and the connecting pipe 16 is fixedly connected to the inner cavity of the rubber ring 6.

[0042] The cylinder 13 is fixedly arranged at the inner cavity side wall of the fixed frame 4, and a movable piston 14 is slidably connected in the inner cavity of the cylinder 13. One end of a connecting rod 15 is fixedly connected to the side wall of one side of the movable piston 14. The other end of the connecting rod 15 penetrates the inner cavity side wall of the cylinder 13 and extends outside the wall. One end of the connecting rod 15 is fixedly connected to the side wall of the limit block 7, and one end of the connecting pipe 16 is fixedly connected to the inner cavity of the cylinder 13. Through the present technical solution, when the limit block 7 moves, the connecting rod 15 can be driven to move, thereby pushing the movable piston 14 to move. Further, the movable piston 14 moves in the inner cavity of the cylinder 13, so that the gas in the inner cavity of the cylinder 13 is transported to the inner cavity of the rubber ring 6 through the connecting pipe 16, so that the rubber ring 6 expands. Further, through the expansion of the rubber ring 6, the gap between the limiting protrusion 5 and the fixed frame 4 can be effectively closed, thereby avoiding the intrusion of external moisture and achieving a better waterproof protection effect.

[0043] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software and methods.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
