Proximity switch mounting base and protective shell thereof

Abstract

The invention discloses a proximity switch mounting base and a protective shell thereof. The proximity switch mounting base comprises a shell, an indicator light group, a tail circuit and a mounting base, wherein the mounting base comprises a mounting port and a connection part; the mounting port is matched with the connection part of a proximity switch; the connection part is connected with the indicator light group; the indicator light group comprises an indicator light circuit board and an indicator light; the indicator light comprises a first indicator light and a second indicator light; the indicator light circuit board is provided with a first connection circuit and a second connection circuit; the first connection circuit is connected with the connection part, the indicator light and the tail circuit, and communicates with the first indicator light; the second connection circuit is connected with the indicator light and the tail circuit and communicates with the second indicatorlight; the shell sequentially covers the indicator light group and the connection part through the tail circuit; the end of the tail circuit and the end of the connection part are shell sealing ends;and the shell is an elastic shell.

Description

technical field [0001] The invention relates to the field of wire end protection, in particular to a proximity switch installation base and a protective case thereof. Background technique [0002] Proximity switch, also known as contactless proximity switch, is an ideal electronic switch sensor. When the metal detection body is close to the sensing area of ​​the switch, the switch can quickly issue electrical instructions without contact, pressure, and sparks, and accurately reflect the position and stroke of the motion mechanism. Even if it is used for general stroke control, its positioning accuracy and operation The frequency, service life, convenience of installation and adjustment, and adaptability to harsh environments are incomparable to ordinary mechanical limit switches. It is widely used in machine tools, metallurgy, chemical industry, textile and printing industries. In the automatic control system, it can be used as the link of limit, count, position control an...

AI Technical Summary

Problems solved by technology

[0003] Due to the non-contact characteristics of the proximity switch, many proximity switches will choose to install an exposed indicator light as a more obvious line opening and closing indication in the use environment to ensure that the proximity switch is in normal operation, but the proximity switch is mostly used for automatic control. system, the exposed indicator light is easily disturbed by the environment, and the effect is not good

[0004] At the same time, the proximity switch is a kind of sensor, and the line has high requirements for shock resistance, tensile resistance, and waterproof performance. However, for the anti-interference protection of the wire head wiring part, a wire head protection box occupying a certain volume is currently used, or an opaque material is used to cover the wiring part. The former occupies a large volume and is not easy to install, while the latter is made of opaque material, making it difficult to judge the status of wiring and proximity switches
