Abstract
Abstract An electrical coaxial precision connector is disclosed that is manufactured from die castings and deep drawn parts. A first connector (80) includes a receptacle contact 86, a conductive body (88) attached at one end to the receptacle contact, a central pin contact (90), and a dielectric member disposed between the pin and the conductive body (88). A second connector (82), which mates with the first connector (80), includes a conductive body (160) having a pin contact (166) formed integral thereto, an inner receptacle contact (162), and a dielectric member (164) disposed between the receptacle contact and the conductive body (160). Each of the connectors includes a retaining ring that loosely encircles a recessed diameter (100, 170) in the connector and secures the connector in an opening (148, 202) in a housing (84). The retaining ring (130) includes camming surfaces (144, 146) on its ends (140, 142) and is made of a relatively soft plastic so that it does not mar the plated surfaces (100, 170) of the connector when assembled thereto.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
231 words
A coaxial electrical connector comprising: (a) a conductive body of unitary construction having an outer pin contact for interconnecting with a receptacle contact of a mating connector, an outer diameter adjacent said outer pin contact, and a hole extending axially therethrough, said hole having a counterbore in an end of said conductive body terminating in a shoulder; (b) an inner receptacle contact arranged coaxially within said outer receptacle contact for interconnection with a pin contact of a mating connector; (d) a dielectric member having a first end in engagement with said inner receptacle contact and said hole of said conductive body and a second end in engagement with said inner receptacle contact and said counterbore adjacent said end of said conductive body, including a flange intermediate said first and second ends in abutting engagement with said shoulder of said counterbore, and wherein said end of said conductive body is deformed to engage said second end of said dielectric member so that said dielectric member is retained between said shoulder and said deformed end; and (e) wherein said conductive body includes a reduced diameter in said outer diameter and said connector includes a retaining ring, formed of a material which is softer than said reduced diameter of said conductive body and having radiused camming surfaces, surrounding a portion of said reduced diameter for holding said connector in an opening in a housing.
Claim 2
Dependent Claim
231 words
A coaxial electrical connector comprising: (a) a conductive body of unitary construction having an outer pin contact for interconnecting with a receptacle contact of a mating connector, an outer diameter adjacent said outer pin contact, and a hole extending axially therethrough, said hole having a counterbore in an end of said conductive body terminating in a shoulder; (b) an inner receptacle contact arranged coaxially within said outer receptacle contact for interconnection with a pin contact of a mating connector; (d) a dielectric member having a first end in engagement with said inner receptacle contact and said hole of said conductive body and a second end in engagement with said inner receptacle contact and said counterbore adjacent said end of said conductive body, including a flange intermediate said first and second ends in abutting engagement with said shoulder of said counterbore, and wherein said end of said conductive body is deformed to engage said second end of said dielectric member so that said dielectric member is retained between said shoulder and said deformed end; and (e) wherein said conductive body includes a reduced diameter in said outer diameter and said connector includes a retaining ring, formed of a material which is softer than said reduced diameter of said conductive body and having radiused camming surfaces, surrounding a portion of said reduced diameter for holding said connector in an opening in a housing.
Claim 3
Dependent Claim
147 words
The connector according to claim 1 wherein said retaining ring is adapted to be loosely received in surrounding engagement with said reduced diameter of said shank, the surface of said reduced diameter being relatively soft and malleable, said ring having an outer wall and an inner wall terminating at a first edge and a second edge spaced from said first edge a distance that is smaller than said reduced diameter, said outer and inner walls being concentric with an axis of said ring, wherein said first and second edges include said radiused camming surfaces that cause said first and second edges to deflect away from each other when said radiused camming surfaces are forced laterally against said reduced diameter until said edges pass over said reduced diameter and resiliently deflect toward each other into said loose surrounding engagement therewith, without marring said surface of said reduced diameter.
Claim 4
Dependent Claim
160 words
An electrical connector having a retaining ring adapted to be loosely received in surrounding engagement with a reduced diameter in an outer surface of said electrical connector for holding said connector within an opening in a housing, the surface of said reduced diameter being relatively soft and malleable characterized by: said retaining ring being formed of a material which is softer than said reduced diameter and having an outer wall and an inner wall terminating at a first edge and a second edge spaced from said first edge a distance that is smaller than said reduced diameter, wherein said first and second edges include rounded camming surfaces that cause said first and second edges to deflect away from each other when said rounded camming surfaces are forced laterally against said reduced diameter until said edges pass over said reduced diameter and resiliently deflect toward each other into said loose surrounding engagement therewith, without marring said surface of said reduced diameter.
