Circuit board connectors

A process for fabricating an electrical connector comprising:

• providing a housing of thermoplastic material having a front surface which will constitute an exterior surface of the connector, a rear surface and a through hole extending in a direction between the front and rear surfaces;
• installing a conductive contact member in the through hole, the conductive contact member having a first portion engageable with a contact of a mating connector and a second portion which is spaced from the first portion and which is held in place in the through hole by the housing so that the through hole is initially at least partially unobstructed between the front and rear surfaces;
• and
• heating a portion of the housing to a softened state while applying a displacement force to displace the heated housing portion to a location to close the through hole, and then allowing the portion of the housing to cool and solidify at that location.
