Abstract
Abstract A pin and socket connector using pin and socket terminals formed into a highly conductive material and using a separate contact band member less resistant to stress relaxation than the material used to form a stamped and formed pin and socket terminals is disclosed. These pin and socket terminals are suitable for use in both sealed and unsealed electrical connectors, employing a secondary lock. The secondary lock has at least one cylindrical projection engaging the corresponding terminals within the cavities from the rear. At least one curved concentric opening radially spaced from a central wire and terminal receiving opening in a rear conductor seal, is configured to receive a corresponding cylindrical secondary lock projections and establish sealing integrity therewith.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
An electrical connector comprising: an insulative housing and at least one contact terminal disposed within a cavity in the insulative housing; a secondary lock member having at least one cylindrical projection extending forward from a base located at the rear of the member and insertable into the rear of a corresponding cavity and engageable with a corresponding contact terminal to fully seat said terminal; latching members disposed on the ends of said base of said secondary lock member and engageable with said insulative housing to secure said secondary lock member thereto; and a seal insertable into the rear of a corresponding cavity, the seal having an inner opening through which a contact terminal can be inserted and at least one concentric curved opening having the same center as the inner opening, each concentric curved opening being dimensioned to receive one corresponding cylindrical projection on the secondary lock and to establish sealing integrity therewith.
Claim 2
Dependent Claim
153 words
An electrical connector comprising: an insulative housing and at least one contact terminal disposed within a cavity in the insulative housing; a secondary lock member having at least one cylindrical projection extending forward from a base located at the rear of the member and insertable into the rear of a corresponding cavity and engageable with a corresponding contact terminal to fully seat said terminal; latching members disposed on the ends of said base of said secondary lock member and engageable with said insulative housing to secure said secondary lock member thereto; and a seal insertable into the rear of a corresponding cavity, the seal having an inner opening through which a contact terminal can be inserted and at least one concentric curved opening having the same center as the inner opening, each concentric curved opening being dimensioned to receive one corresponding cylindrical projection on the secondary lock and to establish sealing integrity therewith.
Claim 3
Dependent Claim
34 words
The electrical connector of claim 1 wherein a semicircular recess is formed on the upper surface of the base, each cylindrical projection being located at lease partially around the periphery of the semicircular recess.
Claim 4
Dependent Claim
16 words
The electrical connector of claim 2 wherein the contact terminals have a generally circular outer surface.
Claim 5
Dependent Claim
92 words
An electrical connector comprising: an insulative housing and at least one contact terminal disposed within a cylindrical cavity in the insulative housing; a secondary lock member having a projection extending from a base, the projection being insertable into the rear of a corresponding cavity and engagable with a corresponding contact terminal; latching means on the secondary lock member engagable with the insulative housing; the connector being characterized in that the secondary lock projection comprises a portion of a cylindrical surface having an axis corresponding to a longitudinal axis of the corresponding cavity.
Claim 6
Dependent Claim
92 words
An electrical connector comprising: an insulative housing and at least one contact terminal disposed within a cylindrical cavity in the insulative housing; a secondary lock member having a projection extending from a base, the projection being insertable into the rear of a corresponding cavity and engagable with a corresponding contact terminal; latching means on the secondary lock member engagable with the insulative housing; the connector being characterized in that the secondary lock projection comprises a portion of a cylindrical surface having an axis corresponding to a longitudinal axis of the corresponding cavity.
Claim 7
Dependent Claim
22 words
The electrical connector of claim 14 wherein the contact terminals comprise either pin or socket terminals having a generally cylindrical cross section.
Claim 8
Dependent Claim
35 words
The electrical connector of claim 5 wherein the insulative housing includes a resilient latch protruding into the upper portion of each cavity, the secondary lock projection extending into the upper portion of the corresponding cavity.
Claim 9
Dependent Claim
44 words
The electrical connector of claim 6 wherein each contact terminal includes a cylindrical bulge in its midsection, and a circular stabilizing ring at the rear of the terminal, the resilient latch engaging the cylindrical bulge and the secondary lock projection engaging the stabilizing ring.
