Method for forming a separable electrical connector
View Patent ↗A method for forming a separable electrical connector having an electrical interface surface includes the steps of molding an interface shell from a thermoplastic, placing the interface shell against an electrical interface portion of a mold cavity and molding a housing within the mold cavity. When placed in the mold cavity, the interface shell provides a barrier to the mold cavity interface portion, wherein the housing is isolated from the electrical interface potion of the mold cavity by the interface shell. The shell has an inner surface and an outer surface and the housing is bonded to one of the inner and outer surfaces, wherein the other of the inner and outer surfaces of the shell defines the electrical interface surface of the electrical connector.
1. A method for forming a separable electrical connector comprising the steps of:
molding an interface shell from a non-rubber material in a first mold to form a semi-rigid to rigid shell, said shell having an inner surface and an outer surface;
removing said shell from said first mold;
placing said interface shell within an interface portion of a mold cavity of a second mold, whereby said shell provides a barrier to said mold cavity interface portion; and
molding a housing within said mold cavity of said second mold, wherein said housing is isolated from said interface potion of said mold cavity by said interface shell during molding and is bonded to one of said inner and outer surfaces of said shell, whereby said shell and said housing are integrally molded and wherein the other of said inner and outer surfaces of said shell defines an interface surface of said electrical connector.
2. The method as defined in claim 1 , wherein said interface shell provides a barrier against contamination of said housing.
3. The method as defined in claim 1 , wherein said interface shell provides a barrier against the formation of mold parting lines in said housing.
4. The method as defined in claim 1 , wherein said interface shell provides a barrier against the formation of mold flashing on said housing.
5. The method as defined in claim 1 , wherein said interface shell provides a barrier against the formation of surface disruptions on said housing.
6. The method as defined in claim 1 , wherein said housing molding step includes the step of injection molding rubber material into the mold cavity to form said housing.
7. The method as defined in claim 1 , wherein said housing is molded from an epoxy material.
8. The method as defined in claim 1 , wherein said interface shell is molded from a material having a color different from that of the housing material.
9. The method as defined in claim 1 , wherein said interface shell is molded from a low coefficient of friction plastic.
10. The method as defined in claim 9 , wherein said low coefficient of friction plastic interface shell has a coefficient of friction less than that of rubber.
