Description

Technical Field

[0001] The utility model relates to the technical field of automobile sensors, in particular to a mileage sensor joint connection structure. Background Art

[0002] The mileage sensor, also known as the vehicle speed sensor, is mainly used to detect the speed of electronically controlled vehicles. It is usually installed next to the output shaft of the gearbox. According to the type, the mileage sensor can be divided into three types: magnetoelectric, Hall and photoelectric. The function of the mileage sensor is not only to detect the vehicle speed, but it can also provide input signals to the control computer to help the control computer complete a number of important operations, including controlling the engine idle speed, controlling the torque converter lock of the automatic transmission, determining the shifting time of the automatic transmission, controlling the opening and closing of the engine cooling fan, and setting and maintaining the cruise control speed. In general, the mileage sensor plays a vital role in the control system of modern cars.

[0003] Since the mileage sensor is usually installed naked next to the gearbox output shaft during use and is connected to the odometer through a wire, the mileage sensor in the prior art is usually connected to the wire using a one-way snap-in wire connector, which makes it inconvenient to disassemble the mileage sensor during subsequent replacement or repair. Moreover, when the vehicle passes through potholes and muddy roads, bumps and splashes of mud and water may occur, causing the connection between the mileage sensor and the connector to become loose due to bumps and shaking, leading to the infiltration of mud, water, dust, etc., which reduces the stability and sealing of the connection between the mileage sensor and the wire, thereby affecting the use effect of the mileage sensor.

[0022] like Figure 1-5 As shown, it is a structural schematic diagram of a mileage sensor joint connection structure in a preferred embodiment of the utility model;

[0023] In this embodiment, a mileage sensor body 1 and a connector 2 connected to the mileage sensor body 1 are included. A plug connector 3 is provided on the top of the mileage sensor body 1. Two wedge strips 4 are provided on the front and rear sides of the plug connector 3. Fixed buckles 5 are provided on the left and right sides of the plug connector 3. A plug terminal 6 is provided at the middle of the top of the plug connector 3. A sealing groove 7 is provided on the outer side of the plug terminal 6 along the periphery of the plug terminal 6. A sealing gasket 8 is provided in the sealing groove 7. The sealing gasket 8 is made of rubber. A connecting cavity 9 is provided inside the connector 2. The plug connector 3 is plugged into the connecting cavity 9. Two wedge grooves 10 are provided on the front wall and the inner rear wall of the connecting cavity 9. Both the wedge strip 4 and the wedge groove 10 are isosceles trapezoidal structures. The wedge strip 4 is embedded in the wedge groove 10 and fits tightly with the inner wall of the wedge groove 10. This structure can effectively improve the connection stability and avoid shaking and loosening between the mileage sensor body 1 and the connector 2. A rotating plate 11 is provided on the left and right sides of the connector 2 for hinged rotation. The two rotating plates 11 represent A fixing card slot 12 is provided on each surface, a connector terminal 13 is provided in the middle of the top wall of the connecting cavity 9, and the connector terminal 13 is used in conjunction with the plug terminal 6. A card embedding convex strip 14 is provided on the outer side of the connector terminal 13, and the card embedding convex strip 14 is arranged along the outer side of the connector terminal 13. The corners of the card embedding convex strip 14 are chamfered to facilitate card embedding in the sealing groove 7. A first card engaging groove 15 is provided at the bottom of one end of the rotating plate 11 away from the connecting cavity 9, and a second card engaging groove 16 is provided on the left and right sides of the connector 2 at the top of the rotating plate 11. The two first card engaging grooves 15 and the two second card engaging grooves 16 are arranged in a mirror image, and a metal spring 17 is fixedly embedded in the first card engaging groove 15 and the second card engaging groove 16. The metal spring 17 is made of tin bronze and has a thickness of 1-2 mm. The material has good elastic deformation ability, can play a role in flipping and resetting the two rotating plates 11 downward, and plays a role in retaining force, so that the two rotating plates 11 will not automatically flip open to both sides, thereby ensuring the fixing effect.

[0024] In this embodiment, the embedding convex strip 14 is embedded in the sealing groove 7, and the embedding convex strip 14 contacts and abuts against the sealing gasket 8. The sealing effect between the mileage sensor body 1 and the connector 2 is improved by the sealing gasket 8. The embedding convex strip 14 is embedded in the sealing groove 7 and abuts against the sealing gasket 8, so that the connection has an embedding effect to improve the sealing, which can further improve the sealing effect.

[0025] In this embodiment, the wedge-shaped strip 4 is embedded in the wedge-shaped groove 10. This structure can effectively strengthen the connection strength between the mileage sensor body 1 and the connector 2. The fixing buckle 5 is embedded in the fixing groove 12. Through this structure, the connector 2 and the mileage sensor body 1 can be fixed.

[0026] In this embodiment, the top corners of the fixing buckle 5 are chamfered, so that the top of the fixing buckle 5 has an inclined surface. When the rotating plate 11 contacts the fixing buckle 5, the inclined surface causes the rotating plate 11 to flip outward.

[0027] Principle of this utility model:

[0028] During installation, the plug connector 3 is inserted into the connection cavity 9, and the wedge strip 4 is inserted into the wedge groove 10, which can effectively improve the connection strength and stability between the mileage sensor body 1 and the connector 2; the embedded convex strip 14 is embedded in the sealing groove 7 and abuts against the sealing gasket 8, which can effectively improve the sealing effect of the connection between the mileage sensor body 1 and the connector 2 to avoid the infiltration of dust and moisture; through the two rotatable rotating plates 11, when the plug connector 3 is inserted into the connection cavity 9, the rotating plates 11 contact the fixed buckle 5 and are fixed by the fixed buckle 5, the two rotating plates 11 are turned toward the two outer sides of the connector 2 at the same time, so that the metal spring sheet 17 is elastically deformed. When the plug-in is completed and the fixing buckle 5 moves to the fixing slot 12, the rotating plate 11 is turned inward by the elastic force generated by the deformation of the metal spring sheet 17, and the fixing buckle 5 is inserted into the fixing slot 12, thereby achieving the fixation between the mileage sensor body 1 and the connector 2. When disassembling, the two rotating plates 11 are turned outward to pull the connector 2 off the plug connector 3 to complete the disassembly, thereby achieving the purpose of facilitating installation and disassembly.

[0029] The utility model provides a mileage sensor joint connection structure, and its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0030] Technologies not described in detail in the present invention are all well-known technologies. Those skilled in the art can easily implement the present invention based on understanding this specification, and the contents shown in the drawings are part of this specification.

[0031] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
