Description

Technical Field

[0001] The utility model relates to the technical field of ABS plug sealing, and specifically relates to an ABS double O-ring sealing structure. Background Art

[0002] ABS plugs are mainly used in vehicles to connect the ABS control unit and related sensors to transmit signals and data, ensuring the normal operation of the ABS system. The position of the ABS plug may vary depending on the vehicle model and manufacturer. The ABS plug usually consists of multiple pins, and each pin corresponds to a different signal or function. For example, in some vehicle models, the pin definition of the T38 pin of the ABS plug may include the right front wheel speed sensor signal, the left front wheel speed sensor signal, the CAN bus signal, the ESP button signal, etc. Through precise connection, these pins ensure that the ABS system can accurately receive and process data from sensors.

[0003] The main function of the ABS plug is to provide electrical connection to ensure that all parts of the ABS system can work together. It enables the ABS control unit to receive signals from the wheel speed sensors, monitor the rotational speed of the wheels, and prevent wheel lock-up by adjusting the braking pressure when necessary. At the same time, the ABS plug also allows the vehicle diagnostic system to connect to the ABS system for fault diagnosis and repair.

[0004] Currently, when connecting, the ABS plug is generally inserted into the wire harness socket in a plug-and-socket manner by the wire harness plug. However, when the common ABS plug is inserted into the socket, only one O-ring is used as the sealing structure on the plug rod. During long-term use, the sealing performance of the ABS plug is not stable enough, which is likely to cause water seepage in the wire harness and lead to a short circuit.

[0005] Therefore, an ABS double O-ring sealing structure is proposed to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment:

[0027] Please refer to Figures 1-4The present embodiment provides an ABS double O-ring sealing structure, including an ABS wire speed plug 1, a docking head 2 fixedly connected to the bottom of the ABS wire speed plug 1, a protective tube 22 connected to the bottom of the docking head 2, a docking plug 25 connected to the bottom of the protective tube 22, two sealing rings 27 mounted on the docking plug 25, a wiring harness socket 3 connected to the bottom edge of the docking head 2, a docking slot 33 for connecting the wiring harness socket 3 to the docking plug 25, and the ABS double O-ring sealing structure is used. When in use, two sealing rings are mounted on the outer ring surface of the docking plug 25. 27, and at the same time, a matching slot 33 matching the matching plug 25 is opened inside the wiring harness socket 3. One end of the matching plug 25 is inserted into the inner side of the wiring harness socket 3 and continuously moved downward to insert the matching plug 25 into the inner side of the matching slot 33. At this time, the two sealing rings 27 are located on the inner side wall of the matching slot 33 and form an extrusion, thereby achieving a sealing effect. This ABS plug adopts a double sealing ring structural design. Compared with a single sealing ring, the sealing effect is more stable. During the long-term use of the ABS, it can ensure that the plug will not seep water and cause a short circuit, thereby effectively improving the service life of the ABS.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, buckles 21 are symmetrically installed on the rectangular planes on both sides of the outside of the docking connector 2, and a slot is opened at one end of the buckle 21. Blocks 32 that match the size of the slot on the buckle 21 are symmetrically installed on the top of the two external side surfaces of the wiring harness socket 3. When the bottom of the docking connector 2 coincides with the top of the wiring harness socket 3, the slot on the buckle 21 is stuck on the block 32. At this time, the docking connector 2 and the wiring harness socket 3 can be clamped. At the same time, the buckle 21 can be separated from the block 32 by bending it outward, thereby facilitating the disassembly and assembly operations between the docking connector 2 and the wiring harness socket 3.

[0029] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, three annular rings 23 are fixedly installed on the outer ring surface of the protective tube 22, and a sealing ring 24 is clamped in the space between each two annular rings 23 on the outer ring surface of the protective tube 22. Two annular sealing grooves 31 are opened on the top of the inner side of the wiring harness socket 3. The outer size of the protective tube 22 matches the size of the top of the inner side of the wiring harness socket 3. After the protective tube 22 is inserted into the inner side of the top of the wiring harness socket 3, it is squeezed to the bottom so that the two sealing rings 24 can be inserted into the inner sides of the two annular sealing grooves 31 respectively. Therefore, the protective tube 22 forms a double-sealing ring sealing structure with the inner wall of the inner top slot of the wiring harness socket 3 through the sealing ring 24, thereby further improving the sealing inside the wiring harness socket 3.

[0030] In this embodiment, ifFigure 2 and Figure 4 As shown in Figure 4 , at the center of the bottom of the slot hole where the mating slot 33 is opened for the mating of the wire harness socket 3 and the protective cylinder 22, two annular sealing grooves 31 are also vertically opened at the bottom of the inner side wall of the mating slot 33. Three annular rings II 26 are vertically fixedly installed on the outer ring surface at the top of the mating plug 25. A sealing ring II 27 is installed in the gap between every two annular rings II 26 on the outer ring surface of the mating plug 25. After one end of the mating plug 25 is inserted into the inner side of the mating slot 33 and pressed down forcefully, the two sealing rings II 27 can be respectively clamped into the inner sides of the two annular sealing grooves 31 on the inner side wall of the mating slot 33. At this time, inside the mating slot 33, a sealing structure with a double-sealing-ring structure design is also adopted to improve the sealing performance inside the mating slot 33.

[0031] Working principle: When the ABS double-O-ring sealing structure is in use, first insert the mating plug 25 into the inner side of the wire harness socket 3, align the positions of the mating buckle 21 and the locking block 32, and insert the mating plug 25 into the inner side of the mating slot 33. At this time, the two sealing rings II 27 can be respectively clamped into the inner sides of the two annular sealing grooves 31 on the inner side wall of the mating slot 33. Therefore, a sealing structure with a double-sealing-ring structure design is adopted inside the mating slot 33 to improve the sealing performance inside the mating slot 33. In addition, when the docking head 2 is inserted into the inner side of the wire harness socket 3 and pressed to the bottom, the two sealing rings I 24 can be respectively inserted into the inner sides of the two annular sealing grooves 31. The protective cylinder 22 and the inner top slot hole inner wall of the wire harness socket 3 form a double-sealing-ring sealing structure through the sealing ring I 24, thereby further improving the sealing performance inside the wire harness socket 3. This ABS plug adopts a double-sealing-ring structure design. Compared with a single sealing ring, the sealing effect is more stable. During the long-term use of the ABS, it can ensure that water does not seep at the plug, resulting in a short circuit of the circuit, thereby effectively increasing the service life of the ABS.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
