Abstract:
A combination plug comprising:an outer housing defining a first end with a pivot device, a second end, a tunnel extending between the first and second ends, at least two first holes communicating the tunnel with a top exterior of the housing, at least two second holes communicating the tunnel with a bottom exterior of the housing, and a locking device formed in the tunnel; a plug base with a rear plate, two tongs each with a first distal end and a second end joined with the rear plate, a threaded hole defined through the rear plate and between the second ends of the tongs, a bridge extending between the tongs from the first distal thereof towards the rear plate, a locking element engageable with the locking device of the outer housing, a fuse chamber with an open first end and a second end, and a cavity surrounded by the rear plate, the tongs and the bridge; two electrically-conductive blades respectively received in the tongs of the plug base and protruding from a front thereof, and at least one electrically-conductive blade having a tooth extending therefrom and through the bridge to close the second end of the fuse chamber; a conductor body sized to be slidingly receivable in the cavity of the plug base, and defining two upright bores, two lateral cutouts respectively intersecting one of the upright bores, and a receiving device; a piston with a threaded exterior engageable in the threaded hole of the plug base, and an engagement device extending from an end face thereof to rotatably engage with the receiving device of the conductor body; a fuse receivable in the fuse chamber of the plug base; and a retaining device pivotally securable with the pivot device of the first end of the housing to close and open the first end of the fuse chamber, whereby electrical wires penetrate the outer housing via either the first holes or the second holes and enter the upright bores and cutouts of the conductor body whereafter the conductor body is received in the plug base which is in turn received in the outer housing, the fuse is secured in the fuse chamber by abutting the tooth and the retaining device, electrical wires penetrate the outer housing via either the first or second holes and enter the upright bores and cutouts of the conductor body and the conductor body is driven away from the rear plate by rotation of the piston such that the tooth of the electrically-conductive blade enters the respective cutout to trap the respective wire and sheathing of the wires is retainedly deformed due to non-alignment of the first holes or the second holes and the upright bores.
