Embodiment Construction

[0027] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0028] This preferred embodiment provides a fuel level sensor. Such as figure 1 with figure 2 As shown, the fuel level sensor includes an electronic tube 1, a buoy 2 disposed on the electronic tube 1, a signal circuit board 3 disposed in the electronic tube 1, a fixing seat 4 disposed at the end of the electronic tube 1, and a shock absorber. A connector 42 is arranged in the fixing seat 4 , and the output end of the signal circuit board 3 is connected to the connector 42 arranged in the fixing seat 4 .

[0029] The overall anti-vibration performance of the sensor is improved by setting the shock absorbing device, and the sensor can be used even in relatively harsh environments and working conditions. The signal circuit board 3 can be directly fixedly connected with the connector 42 in the fixed ...

Abstract

The invention discloses a fuel level sensor which belongs to the field of sensor devices and is designed to solve the problem that the existing device has poor anti-seismic performance. The fuel level sensor of the invention comprises an electron tube, a buoy arranged on the electron tube, a signal circuit board arranged in the electron tube, and a fixed base arranged at the end of one side of the electron tube. A connector is arranged in the fixed base, and the output end of the signal circuit board is connected to the connector arranged in the fixed base. The sensor further comprises a damping device. The anti-seismic performance of the fuel level sensor is enhanced, the installation process is simplified, and the sealing performance is improved. The signal circuit board can be better fixed. The problems such as facture of the internal structure of the signal circuit board and breakage of the external electron tube in a vibration environment are solved.

Description

technical field [0001] The invention relates to the field of sensor devices, in particular to a fuel level sensor. Background technique [0002] The reed switch fuel level sensor for vehicles mainly includes electronic tubes, floats, signal circuit boards and steel head flanges. The buoy is arranged outside the electron tube, the signal circuit board is arranged inside the electron tube, and the steel head flange is arranged at the end of the electron tube. [0003] The main defects of the fuel level sensor structure include: 1. The anti-vibration performance is poor, and the connection between the electronic tube and the steel head flange is prone to breakage; 2. The electronic tube and the steel head flange are connected by welding, resulting in high production costs; 3. 1. The signal circuit board in the electronic tube is easy to cause the magnetic ring tube to break when it is shaken or vibrated. Contents of the invention [0004] An object of the present invention ...
