ABSTRACT:
The invention herein relates an improved stricture assembly-type power plug, specifically referring to a kind of power plug structure that can be rapidly installed without screws or soldering which has an outer shell that is fitted over an inner shell. The inner shell is of an I-shaped cross sectional profile having a center separator that is hollow with an opening at one end utilized to contain the power cord inserted through the outer shell. The too wires of the power cord are stacked vertically due to the narrow space within the center separator and, there is a channel formed on each of the exterior sides of the center separator to position the aforesaid wires. Two metal electrodes are respectively inserted in the recessed sections along the sides of the center separator and each electrode has a sharp point extending into the recessed section to pierce the covering of the power cord wires and thereby achieve direct contact with the conductors therein. There is also a nub on the exterior walls of each of the two electrodes, such that when the inner shell is inserted into the outer shell, the nubs become engaged in the catch slots on the inner walls of the outer shell to both secure and prevent the removal of the inner shell.
