Abstract

A low profile electrical connector assembly for insertion into a mating socket having a connector body whose pin to lead wire input configuration is non-linear. The connector body includes a nose-like projection which acts to reduce the lateral stress imposed on the connector pins when the assembly is removed from its mating socket by a pulling force exerted on the lead wires.

Claims

1. An electrical connector assembly for association with lead wires and for insertion into a mating socket, said electrical connector assembly comprising:

a connector body having a top portion, a bottom portion and at least a first, second and third side portions, said first side portion receiving the lead wires,

conductive pins projecting from said bottom portion and having a certain characteristic yield strength,

said second and third side portions disposed relative said first side portion to meet at a point approximately opposite the midpoint of said connector body first side portion to form a nose-like projection, said second and third side portions and said nose-like projection being disposed such that

a force exerted on said connector body first side in response to a pull on the lead wires causes said connector body to first pivot about said nose-like projection and then cam against the mating socket along either said second or third side portions resulting in the removal of said conductive pins from the mating socket without said pins experiencing a lateral force which exceeds their yield strength.

2. An electrical connector assembly according to claim 1 wherein said conductive pins are in a limnear array and said array is parallel to said first side.

3. An electrical connector assembly according to claims 1 or 2 wherein said top portion of said connector body includes four walls defining a well with a first wall being part of said first side portion of said connector body and said first wall having ports to receive said lead wires.

4. An electrical connector assembly according to claim 3 wherein said well includes openings which define holes connecting between said connector body bottom and top portion, said openings receiving said connector pins which project from said connector body bottom portion.

5. An electrical connector assembly according to claim 4 wherein said connector pins and lead wires are electrically joined by a solder joint located in said well with said well being filled with potting compound to protect said solder joint.
