Technical Field

[0001] The utility model relates to the technical field of PLC sockets, in particular to a PLC contact socket with a contact pin indicator light. Background Art

[0002] PLC sockets usually consist of sockets, plugs and connecting wires. Sockets and plugs are divided into different models and specifications to meet different industrial control needs. Connecting wires are used to connect PLCs with external devices.

[0003] In the prior art, a PLC socket generally has an indicator light for each plug, the significance of which is that the indicator light can clearly display the status of the corresponding plug of the PLC contact socket, so that the operator can quickly understand the operation status of the equipment.

[0004] However, the high temperature, high dust and high humidity working environment in the factory will seriously affect the working life of the indicator light. It has been tested that the normal working life of the indicator light bead is generally thousands of hours, which is one to two hundred days. If the indicator light bead is damaged, the equipment needs to be shut down and a new PLC socket needs to be replaced. The operation is cumbersome and affects normal production. Therefore, a new PLC contact socket with a contact indicator light is proposed. The double indicator light group design is adopted, and a set of spare indicator lights are designed to effectively solve the above problems. Utility Model Content
