ABSTRACT OF THE DISCLOSURE The invention relates to the field of electrical connectors which utilize hollow shells and internal insert members. It has often been difficult to accurately locate the insert members in exact pre- determined axial positions between and snugly against immovable stop surfaces of the shells, since the manufacture of the insert members usually results in some variation in the axial dimension. Retention techniques utilizing adjustable stop surfaces on separate shell members or on separate retaining members add to the cost and complexity of electrical connectors. Therefore, it is desirable to provide an elec- trical connector in which the insert member is retained between and snugly against immovable stop surfaces in which some variation in axial dimension in the insert member is permitted. The present invention provides such an electrical connector, which includes a hollow housing member with an internal restricted passageway, an adjacent radial shoulder and a reference surface axially spaced from the shoulder oppositely to the passageway. Also included is an insert member snugly retained against axial movement, between the shoulder and the reference surface. The insert member includes a restraining surface in abutment with the shoulder, and shaped by plastic deformation of a weakened peripheral surface portion on the insert member by the wall of the restricted passageway. The insert member before deformation includes the weakened peripheral surface portion and an adjacent pro- tective collar which protects the weakened portion from deformation until the collar has passed through the restricted passageway.
