Arcuate slide guide slots are disposed on the electro-conductive module. Rotary buttons are pivotally disposed in the case main body. Each rotary button has a movable section. A pin is disposed on the movable section. The pin is extended into the slide guide slot. At least one abutment leaf spring is pivotally disposed between the rotary button and the electro-conductive module. When a conductive wire passes through the wire plug-in port into the lateral side of the electro-conductive module, the rotary button can be driven to make the movable section gradually displace from a section of the abutment leaf spring near the pivotally rotational center to an outer lateral side. The abutment leaf spring is pushed to engage with the conductive wire.
