Description

Technical Field

[0001] The utility model relates to the technical field of sensor equipment, in particular to an oil pressure sensor with good stability. Background Art

[0002] The oil pressure sensor is a micro-electromechanical system, which refers to a micro-electromechanical system that integrates micro sensors, actuators, signal processing and control circuits, interface circuits, communications and power supplies. The oil pressure sensor can be mass-produced with high precision and low cost using design technology and manufacturing processes similar to integrated circuits, thereby opening the door for consumer electronics and industrial process control products to use sensors in large quantities at low cost, making pressure control simple, easy to use and intelligent. The existing oil pressure sensor has a simple structure and poor protection performance. In actual use, it is easy to be damaged by the vibration force generated by the engine and the external pressure, which affects the service life of the pressure sensor and has certain limitations.

[0003] The application number is CN201922139829.0, which discloses an oil pressure sensor, including a sensor body, wherein the surface of the sensor body is sequentially sleeved with two fixed plates from top to bottom, and both sides of the sensor body are fixedly connected with a buffer box, and the inner cavity of the buffer box is provided with a pressure block, and the top and bottom of the pressure block are provided with a moving block, and the side of the moving block close to the sensor body is fixedly connected with a first spring, and both sides of the sensor body are provided with a protective plate, and the top and bottom of the pressure block away from the sensor body are fixedly connected with a connecting rod. The utility model solves the problem of poor protection performance of the existing oil pressure sensor by providing a sensor body, a fixed plate, a buffer box, a pressure block, a moving block, a first spring, a protective plate, a connecting rod, a baffle, a fixed box, a second spring, a pressure plate, a pressure rod, a sliding rod, a fixed block, a sliding sleeve, a third spring and a support bar. The oil pressure sensor has the advantage of good protection performance and is worthy of promotion.

[0004] The oil pressure sensor disclosed in the above document has the following defects: during use, the pressure sensor needs to be fixedly mounted on the engine for cooperation. When the engine is operating, it generates vibrations, which will cause the sensor to vibrate. The structure does not have a corresponding structure to ensure a firm connection between the sensor and the wiring, so the sensor and the wiring become loose, reducing the stability of the sensor.

[0005] It can be seen from this that the existing pressure sensor does not have the function of reinforcing the connection between the port and the wiring, and it is necessary to improve the existing deficiencies and provide a function that can reinforce the connection between the port and the wiring.
