Description

Unlocking device for industrial Ethernet connector

Technical Field

The utility model relates to an automation equipment's connector field particularly, relates to an unlocking device for industrial ethernet connector.

Background

In industrial controllers of the type of PLC components concerned, industrial PCs, human-computer interaction, etc., a RJ45 connector is usually used to implement an industrial ethernet/Profinet plug connection. A conventional RJ45 connector makes a plug connection through a plug and a socket. The plug is provided with the locking elastic sheet, and the plug can be pulled out of the socket only by pressing the locking elastic sheet when the plug is unlocked and connected. In this context, there is more or less hindrance to the insertion and extraction of the plug. As a particular additional challenge, many different forms of connectors are currently in use. They may be different in unlocking operation and in appearance. In the case of an assembly where the connector is not easily accessible, manual operation to unlock is hardly or not possible at all.

The prior art is mostly implemented as follows, the plug at the ethernet terminal has an operation aid. In some cases, however, it is difficult to perform the operation (in different industrial applications), or the aids are not directly accessible, so that the unlocking operation is hindered and made more difficult. In particular, in many apparatuses, a plug and a socket are arranged at a deep position, and in such a case, it is difficult for an operation auxiliary tool such as a screwdriver to be pushed to an operation position, and it is difficult to achieve a truly functional unlocking operation. In addition, the equipment cabinet may be mounted in a switchgear cabinet, in which case the lighting is poor and the connectors are difficult to access. In most cases, the operating position must be fumbled or the socket found through multiple attempts. This is time consuming during the unlocking process and there is no dismounting device associated with Rj45 in industrial applications today.
