Method for forming an electrical connector with voltage detection point insulation shield
View Patent ↗In a method for forming an electrical cable connector having a voltage detection test point, an insulative shield is first molded from a thermoplastic and a conductive voltage detection test point terminal is inserted within the plastic insulative shield. After the pre-assembled insulative plastic shield and test point terminal are positioned adjacent the opening of the conductive outer shield, and after the conductive outer shield and an internal conductor are positioned within a mold cavity, an inner insulative housing is molded within the conductive outer shield and around the internal conductor.
1. A method for forming an electrical connector having a voltage detection test point, the method comprising the steps of:
molding an insulative shield from a thermoplastic;
inserting a conductive voltage detection test point terminal within said plastic insulative shield;
molding an outer shield from a conductive material, said conductive outer shield having an opening formed therethrough;
placing said pre-assembled insulative plastic shield and test point terminal adjacent said opening of said conductive outer shield;
placing said conductive outer shield and an internal conductor within a mold cavity, wherein said conductive outer shield surrounds said internal conductor; and
molding an inner insulative housing within said conductive outer shield and around said internal conductor, wherein said insulative housing is molded to said pre-assembled insulative plastic shield and said test point terminal, whereby said insulative plastic shield is held by said inner insulative housing and said test point terminal is capacitively coupled to said internal conductor for external testing of a voltage of said connector.
2. The method for forming an electrical connector as defined in claim 1 , wherein said connector is a loadbreak power cable elbow connector.
3. The method for forming an electrical connector as defined in claim 1 , wherein said conductive outer shield has a circular opening formed therethrough and said plastic insulative shield is an annular ring substantially surrounding said voltage detection test point terminal.
4. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield is made from a low coefficient of friction plastic material.
5. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield includes structure which engages cooperating structure provided on said test point terminal for pre-assembling said terminal to said plastic insulative shield prior to bonding said pre-assembled terminal and plastic insulative shield to said inner insulating sheath.
6. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield provides a barrier against contamination of said inner insulative housing during molding of said housing.
7. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield provides a barrier against the formation of mold parting lines in said inner insulative housing during molding of said housing.
8. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield provides a barrier against the formation of mold flashing on said inner insulative housing during molding of said housing.
9. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield provides a barrier against the formation of surface disruptions on said inner insulative housing during molding of said housing.
10. The method for forming an electrical connector as defined in claim 1 , wherein said plastic insulative shield is separately molded from a different colored material than that of said conductive outer shield to provide an indication of an operating voltage of said connector.
