Plastic shell for mounting connection terminal and connection terminal

A plastic shell for mounting a connection terminal, comprising a main body configured as an integral single component;

• the main body comprises a top surface and a bottom surface that are opposed to each other, the bottom surface is depressed toward the top surface to form an internal space for accommodating a conductive terminal, the internal space is provided with a connecting portion for mating with a clamping portion of the conductive terminal;
• a front end surface of the main body is provided with a wire insertion hole for inserting a wire into the conductive terminal, and the wire insertion hole is communicated with the internal space;
• the top surface is cut and extends downward to the bottom surface of the main body at an entrance of the the wire insertion hole, so as to form a first cutting surface at the front end surface of the main body and a second cutting surface at the bottom surface of the main body, wherein the first cutting surface is located at upper position of the wire insertion hole and the second cutting surface is located at lower position of the wire insertion hole, a projection of the first cutting surface and a projection of the second cutting surface in a direction which is vertical to a direction of the wire insertion hole are not overlapped;
• wherein the front end surface of the main body forms a guiding area centered on the wire insertion hole, and the guiding area is configured to guide wires to be inserted into the wire insertion hole, wherein the guiding area is not vertical to the first cutting surface.
