Abstract:
A power source cable connector comprising:a rod-shaped plug for connecting a terminal of a first power source cable; a cylindrical receptacle for connecting a terminal of a second power source cable; a first cylindrical casing housing therein said rod-shaped-plug; a second cylindrical casing housing therein said cylindrical receptacle; a first cable inlet cylindrical portion formed on a rear end of said first cylindrical casing; a second cable inlet cylindrical portion formed on a rear end of said second cylindrical casing; an externally fitting cylindrical portion formed on a front end of said first cylindrical casing and having a basal portion, a first annular engagement groove being formed in an outer peripheral surface of said basal portion of said externally fitting cylindrical portion; an internally fitting cylindrical portion formed on a front end of said second cylindrical casing and having a basal portion, a second annular engagement groove being formed in an outer peripheral surface of said basal portion of said internally fitting cylindrical portion, said internally fitting cylindrical portion being fitted into said externally fitting cylindrical portion and said rod-shaped plug being inserted into said cylindrical receptacle, thereby connecting said first power source cable and said second power source cable together; a cylindrical protector externally fitted to an outer periphery of a fitting portion between said externally fitting cylindrical portion and said internally fitting cylindrical portion, a first annular engagement rib formed on an inner peripheral surface at a first end of said cylindrical protector being engaged in said first annular engagement groove of said basal portion of said externally fitting cylindrical portion, and a second annular engagement rib formed on said inner peripheral surface at a second end of said cylindrical protector being engaged in said second annular engagement groove of said basal portion of said internally fitting portion, a first annular tightening groove being arranged on an outer peripheral surface at said first end of said cylindrical protector, a second annular tightening groove being arranged on said outer peripheral surface at said second end of said cylindrical protector; a first tightening band arranged in said first tightening groove for compressing said first end of said cylindrical protector, said first tightening band being located at a same axial position of said cylindrical protector as said first annular engagement rib such that a compression force of said first tightening band is imparted to said first annular engagement groove of said externally fitting cylindrical portion via said cylindrical protector; and a second tightening band arranged in said second tightening groove for compressing said second end of said cylindrical protector, said second tightening band being located at a same axial position of said cylindrical protector as said second annular engagement rib such that a compression force of said second tightening band is imparted to said second annular engagement groove of said internally fitting cylindrical portion via said cylindrical protector.
