Electrical connector insert retention assembly

An electrical connector member comprising

• a metallic housing including a portion integrally formed in a one-piece construction with an inner axially-extending cavity, and axially opposed and separated first and second opposed radial shoulders,
• plastic insert means moved axially into said cavity and toward said first shoulder and into snug engagement with said shoulders for confining said insert means from axial movement, said insert means including a portion permanently deformed beyond its elastic limit and gripped by one of said shoulders, and
• at least one contact member carried by said insert means.

An insert member for axial movement in a first direction into a restricted internal passageway of a housing of an electrical connector member to reach a position axially at least partially beyond and restricted passageway, comprising

• a body member having a longitudinal axis,
• a resilient protective outer collar member on said body member dimensioned to be compressed by said housing during axial movement in said passageway and including a peripheral surface area sufficient to withstand said compression without substantial permanent deformation, and
• a weakened collar member in juxtaposition to said protective collar member in a direction opposite said first direction, said weakened collar member being dimensioned to be compressed in said passageway when said protective collar has passed therethrough and including a peripheral surface area insufficient to withstand said compression without permanent plastic deformation.
