Description

Technical Field

[0001] The utility model relates to the field of proximity switches, in particular to a separable proximity switch. Background Art

[0002] A proximity switch is a position switch that can be operated without mechanical direct contact with a moving part. When an object approaches the sensing surface of the proximity switch to the operating distance, the switch can be actuated without mechanical contact and applying any pressure, so as to drive a DC electrical appliance or provide a control instruction for a computer device. Most of the existing proximity switches are as Figure 1 shown, composed of a sensing head and an indicator. The problem with this technical solution is that the existing proximity switches are usually of an integrated structure, and the length of their wires is also limited. In some special application scenarios, there may be problems of inconvenient installation and maintenance. Therefore, a separable proximity switch is proposed. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: the existing proximity switches are usually of an integrated structure, and the length of their wires is also limited. In some special application scenarios, there may be problems of inconvenient installation and maintenance.

[0004] To solve the problems existing in the prior art, the utility model provides a separable proximity switch, which includes a sensing head, a signal wire and a controller. A first slot is provided at the bottom of the sensing head, a second slot is provided at the top of the controller, and a first plug and a second plug are respectively provided at the top and bottom of the signal wire.

[0005] Further, the specifications of the first slot and the first plug are adapted to each other, and the specifications of the second slot and the second plug are adapted to each other. The staff inserts the first plug of the signal wire into the first slot of the sensing head and inserts the second plug into the second slot of the controller to complete the quick connection work. During use, if a certain part fails or is abnormal, it is not necessary to remove all parts for repair and maintenance. Only by unplugging the plugs can different parts be separated for corresponding repair and maintenance work.

[0006] Further, the length of the signal wire can be selected according to the usage situation. The staff can select a signal wire with a corresponding length according to the requirements, which is convenient for detection and control at different positions. Selecting a shorter signal wire for short distances not only facilitates the installation and storage of the wire, but also the signal transmission for short distances is faster. For some detection environments with potential safety hazards, selecting a long-distance signal wire allows the staff to use the controller to check and control at a location far from the dangerous detection point.

[0007] Further, a display screen is provided at the top of the controller surface, and control buttons are provided on the controller surface at the bottom of the display screen. The detection data of the induction head is displayed through the display screen, and the operating state of the induction head is controlled by operating the control buttons.

[0008] Further, a protective cover is provided on the periphery of the top of the induction head, and a threaded ring adapted to the internal threaded groove of the protective cover is provided on the top of the periphery of the induction head. The staff can screw the protective cover onto the threaded ring on the periphery of the induction head to install the protective cover on the induction head to protect it, which is convenient for the staff to protect the induction head when it is not in use.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] During the use of the present utility model, if a certain part fails or is abnormal, it is not necessary to disassemble all parts for maintenance. Only by unplugging the plug can different parts be separated for corresponding maintenance work. The staff can also select signal lines of corresponding lengths according to needs, which is convenient for detection and control at different positions. Selecting a shorter signal line for short distances not only facilitates the installation and storage of the wire, but also enables faster short-distance signal transmission. For some detection environments with potential safety hazards, selecting a long-distance signal line allows the staff to use the controller to perform detection and control work away from dangerous detection locations, increasing the flexibility and scope of application of the device.
