The first cable unit comprises a plurality of plug pins connected with an electric wire, a pin housing having a plurality of connection grooves disposed at certain intervals for insertion of the plug pins, and a plug supporter fixing the plug pins at the rear side of the plug pins.
- The plug pins are configured in a manner so that a portion mounted in the pin housing has a larger diameter than a portion exposed to the outside of the pin housing.
- The connection groove includes a support part, which supports a stepped portion formed on the outer circumference of the plug pin.
- An exterior of the first cable unit, in which the plug pin, the pin housing and the plug supporter are assembled, is implemented by molding of polyvinyl chloride (PVC).
- The second cable unit comprises a plurality of pin sockets receiving the plurality of plug pins; an outlet cover supporting one ends of the pin sockets; and a pin socket housing supporting the other ends of the pin sockets.
- The outlet cover comprises a plurality of hollow depressions for receiving and fixing the pin sockets.
