Problems solved by technology

In the above-mentioned manufacturing process, the method of welding after threading is adopted, which is very difficult to operate and may easily cause poor solder joints; moreover, the curing time of epoxy resin is longer, which will also slow down the pace of manufacturing
In addition, the epoxy resin is easy to fall off after a long time of use, making the reliability of the magnetic induction switch poor

Abstract

The invention aims at providing a magnetic induction switch which is convenient to manufacture and is high in reliability and a manufacturing method of the magnetic induction switch. The magnetic induction switch comprises a shell and a sensor. A sensor accommodating cavity is arranged in the shell, one end of the sensor accommodating cavity is open, and the sensor accommodating cavity is providedwith a glue injection port connected with an external portion. The sensor is located in the sensor accommodating cavity, a lead of the sensor is led out from the open end of the sensor accommodatingcavity, and the sensor accommodating cavity is filled with a glue. The magnetic induction switch is simple and convenient to manufacture, the sensor and the shell are fixed very stably, and the magnetic induction switch has high reliability and a long service life and is very suitable for large and small household appliances.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a magnetic induction switch and a manufacturing method thereof. Background technique [0002] The magnetic induction switch belongs to a kind of proximity switch, which uses the working principle of the magnetic field to convert the non-electrical or magnetic quantity into the desired electrical signal through the change of the positional relationship between the sensor and the object, so as to achieve the purpose of control or measurement. Magnetic induction switches have strong anti-interference ability, good waterproof performance, long action distance, and high temperature resistance, and are used in large and small household appliances. Such as Figure 1~3 As shown, the structure of the traditional magnetic induction switch is as follows: it includes a housing and a sensor, the housing is provided with a groove with one side opening, the sensor is placed in t...
