The invention provides an outer sealing device for an automotive sensor. The outer sealing device for the automotive sensor comprises a base board, a swing block, a punch fixing frame and a driving air cylinder. When the outer sealing device for an automotive sensor is used, the end, needing sealing, of the automotive sensor is inserted into an automotive sensor sealing hole of the punch fixing frame, then the driving air cylinder drives a moving end of the swing block to move, further a rotating end of the swing block rotates around the axis of a round containing cavity, and therefore a plurality of sections of cam curves on the inner wall of the round containing cavity push punches to move inwards, and the inner side ends of the multiple punches are squeezed in a splicing mode to enable one end of the automotive sensor sealing hole to be well sealed. The automotive sensor can bear big pressure after being sealed through the outer sealing device for the automotive sensor, a better sealing effect can be achieved, and further the quality of the automotive sensor can be effectively improved. The outer sealing device for the automotive sensor further has the advantages of being convenient to use and repair, simple in structure and the like.
Description
technical field [0001] The invention relates to a sealing device, in particular to a device for sealing a vehicle sensor cable, a sealing plug and an outer metal shell. Background technique [0002] The sensor is an indispensable and important electronic component in the car. It detects the temperature, pressure, position, angle, acceleration, flow, distance and other physical quantities of the car; it detects the water temperature, oil temperature, exhaust temperature and concentration of the relevant parts of the vehicle. , cylinder pressure, tire pressure, brake pressure and other actual status. Through these tests and send feedback information to the ECU, the ECU will calculate, analyze, process and store the information, and send the best control parameter instructions to the relevant controller to improve the power and economy of the car. It controls and adjusts the running state of the vehicle, improves the running performance and efficiency of the vehicle, reduces c...
