Patent number: 5871373Abstract: The electrical connector may include a housing, a contact, a secondary lock, a grommet, a backplate, a bolt, a contact removal tool, and a splash guard. The housing includes openings which receive the contacts. The grommets are positioned in cavities at the rear of the housing. The housing and backplate are designed so that the grommets are subjected to compressive forces in order to enhance the sealing characteristic of the grommets. As the contact is inserted, a locking tab engages an opening in the contact and prevents the contact from being removed from the housing. The secondary locks will increase the retention of the contact in the electrical connector. In addition, the secondary lock may include a feature which permits the partial insertion and retention of the secondary lock prior to insertion of the contact. The secondary lock also assures that the contacts have been properly inserted.Type: GrantFiled: February 23, 1996Date of Patent: February 16, 1999Assignee: Labinal Components and Systems, Inc.Inventors: Louis S.
