Abstract: The middle section and the tail section are mounted in a wire inlet of a terminal device. The aid sleeve is formed with an internal guide hole. A wire collection section is disposed on one side of the head section distal from the middle section. A recessed guide channel is disposed on one side of the wire collection section proximal to the guide hole. The recessed guide channel includes two lateral outer arched channels with larger curvature radius. The two lateral outer arched channels gradually extend toward a middle bottom face to form an inner arched channel with smaller curvature radius. The recessed guide channel can gradually bind the forked conductor end section of a multi-strand conductive wire, whereby the wire can be quickly plugged into the guide hole.

Abstract: A modularized structure of switch wire connection device includes an assembling support and a wire connection module. The assembling support has a first side and a second side. The first and/or the second sides are formed with assembling sections for assembling with the wire connection module. The wire connection module includes a first wire connection module and/or a second wire connection module each having a case. The case defines a chamber for receiving and enclosing electrical contact components including conductive members. The case is formed with a mounting section for connecting with the assembling section of the assembling support. Accordingly, the wire connection module is detachably mounted on the assembling support as an integrated form. The modularized structure enables an operator to easily assemble/disassemble the components and change the switch specification between normally open mode and normally closed mode and enhance insulation effect to avoid electric arc.
