Sealed pass-through electrical connector

A pass-through electrical connector assembly comprising:

• a body of an electrically insulative and somewhat yieldable plastic or rubber material;
• at least one through-hole formed in said body;
• and
• an electrically conductive pin forced into said through-hole and retained in said body, said pin having:
• first and second ends each having a recess therein constructed to receive and have permanently attached thereto a separate electrically conductive wire;
• an intermediate solid portion between said recesses constructed to separate said wires and provide a fluid-tight seal between said wires and said pin;
• a tip adjacent said first end of said pin, said tip having at least one barb constructed to engage said body when said pin is forced into said through-hole;
• a head formed adjacent said second end of said pin, said head having a shoulder constructed to engage said body when said pin is forced into said through-hole;
• and
• a circumferentially continuous exterior surface between said ends press-fit into said through-hole of said body with an interference fit with said body and forming a fluid-tight seal between said pin and said body;
• wherein said body has at least two through-holes formed in said body and adjacent through-holes are axially offset relative to each other so that the shoulders of the pin received in adjacent through-holes are axially offset relative to each other.

A pass-through electrical connector assembly comprising:

• a body of an electrically non-conductive and somewhat yieldable material;
• at least two through-holes each formed in said body;
• and
• a separate pin of an electrically conductive material forced into each one of said through-holes and retained in said body, each said pin having:
• a shank with opposed ends each constructed to receive and have permanently attached thereto a separate wire;
• a solid portion between said wires received on said opposed ends and providing a fluid-tight seal between said wires and said pin;
• a tip formed adjacent one end of said pin, said tip having at least one barb constructed to engage said body when said pin is forced into said through-hole;
• a head formed adjacent the other end of said pin, said head having a shoulder constructed to engage said body when said pin is forced into said through-hole;
• and
• an intermediate portion of said shank having a circumferentially continuous exterior surface press-fit within said through-hole of said body with an interference fit with said body thereby forming a fluid-tight seal between said pin and said body.

A method of forming a pass-through electrical connector assembly comprising:

• providing a body of an electrically non-conductive and somewhat yieldable plastic or rubber material having at least one through-hole therein with a shoulder adjacent to the through-hole,
• providing an electrically conductive pin having a shank with opposed ends and at least one of the ends constructed to receive and have permanently attached thereto an electrically conductive wire,
• a tip having a barb adjacent one end,
• a head having a shoulder adjacent the other end, and
• an intermediate portion having a circumferentially continuous exterior surface with a maximum diameter larger than the minimum diameter of the through-hole of the body;
• inserting the tip of the pin into the through-hole and forcing the barb into and through the through-hole with the barb disposed over a portion of said shoulder adjacent to the through-hole and the intermediate portion into the through-hole to provide an interference fit of at least the circumferentially continuous exterior surface in the body providing a fluid-tight seal between the pin and the body.
