Therefore, the installation quality of the connection cassette is very high, and the connection quality between the connection cassette and the conduit connection section 26 must be effectively ensured, otherwise the post repair is very difficult.

in the building construction process, the junction box 15 is one of the electrical accessories, because the electric wires used in the building are inserted into the threading pipe (also called as electric wire pipe, usually steel pipe, etc.), and the junction of the electric wires (for example, the part where the wire is longer or the electric wire pipe needs to be turned) is used as a transition part, the threading pipe needs to be connected with the junction box, and the electric wires in the threading pipe are connected in the junction box 15, so that the junction box 15 plays a role in protecting and connecting the electric wires.

The inner end of the conduit connecting section 26 is inserted into the junction box 25, the outer end of the conduit connecting section is connected with the connecting joint 30, the conduit connecting section 26 is connected with the connecting joint 30 in a threaded connection mode, and the connecting joint 30 is a threaded joint.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, changes and equivalent structural changes made to the above embodiment according to the technical spirit of the present invention still fall within the protection scope of the technical solution of the present invention.
