Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to a network communication filter. Background Art

However, the connection between the wire and the terminal does not have an auxiliary traction function, which can easily cause the wire to loosen or even fall off, affecting the use effect. Therefore, it is necessary to design a network communication filter to solve the above problem. Utility Model Content

[0006] The clamping mechanism includes a traction frame movably inserted into the storage groove, a clamping seat fixedly connected to the free end of the traction frame, and a push handle fixedly connected to the end surface of the traction frame;

[0007] The protection component comprises a spring seat fixedly connected to the outer wall of the shell, and a protection plate fixedly connected to the end surface of the spring seat.
