Self-locking structure of evaporator sensor

Abstract

The invention provides a self-locking structure of an evaporator sensor and belongs to the evaporator sensor technical field. The sensor body (1) of the evaporator sensor is installed in a mounting clamping opening (2) of an evaporator; the surface of the mounting clamping opening (2) is provided with a protruding clamping block (3); the sensor body (1) is provided with an L-shaped mounting clamping groove (4); and when the sensor body (1) is mounted in the mounting clamping opening (2), the clamping block (3) at the surface of the mounting clamping opening (2) is set to a structure which can be clamped into the mounting clamping groove (4) of the sensor body (1). The self-locking structure of the evaporator sensor of the invention has the advantages of simple structure and low manufacturing cost. With the self-locking structure adopted, the assembling of the sensor body into the mounting clamping opening of the evaporator and the disassembly of the sensor body from the mounting clamping opening of the evaporator can be realized conveniently and fast through forwarding and reversely rotating the sensor body, and at the same time, after the sensor body is installed, self-locking can be realized, and the falling of the sensor body after long-term use can be avoided.

Description

technical field [0001] The invention belongs to the technical field of evaporator sensors, and more specifically relates to a self-locking structure of evaporator sensors. Background technique [0002] During the assembly process of the air conditioning system, assembling the evaporator temperature sensor has always been a relatively difficult and laborious task. The installation of the temperature sensor requires that the sensor can be disassembled repeatedly without damage, and that the sensor should be installed firmly. Therefore, in the installation structure The design is very demanding. The structure in the prior art is to realize the connection between the sensor body (shaft) and the installation bayonet (hole) through the interference fit between the shaft and the hole, so as to meet the requirements of repeated disassembly and assembly and safe and firm fixing of the sensor. However, in actual production, the temperature sensor body of the plastic material manufact...

AI Technical Summary

Problems solved by technology

However, in actual production, the temperature sensor body of the plastic material manufactured by the mold is not well controlled due to the shrinkage rate of the material and the process control, resulting in a very low product qualification rate! This not only affects the assembly of the sensor, but also the sensor cannot meet the requirements of repeated disassembly and reliable installation. Therefore, after long-term use, the gap between the sensor and the mounting bayonet becomes larger, and it cannot be fixedly installed, or it is easy to loosen and fall off under vibration.
