[0002] With the rapid development of industrial automation and Internet of Things technology, the single-pair Ethernet SPE connector, as a new type of Ethernet connection technology, has the advantages of POE support, low cost, small space occupation, high frequency and high speed, high reliability and high adaptability, and is widely used in industrial applications such as robots, automation control, industrial Internet of Things and digital factories.
[0003] The current common connection means of the SPE connector is that the connection between the wire end and the board end is realized through a simple plug-in structure. This structure is simple and easy to use, but the mechanical stability is poor and it is easy to fail after long-term use. Another means is to use a spring locking mechanism to keep the connector stable through the elastic force of the spring, but this way is easy to fail when the device environment is unstable, such as when the device shakes.

[0014] Optionally, anti-skid lines are arranged on the side of the pressing plate away from the pressing head.
[0015] By using the above technical scheme, the anti-skid lines increase the friction between the fingers of the user and the pressing plate, and facilitate the user to apply force to the pressing plate.
[0016] Optionally, an overpressure groove is arranged on the inner core and located below the pressing head.
[0017] By using the above technical scheme, the pressure groove is located below the pressing head, and when the pressing head is pressed downward, additional space can be provided for the inner core, thereby avoiding damage of the pressing head caused by pressure.
