Abstract
Abstract An electrical connector comprises; a conductive outer shell 2 for releasable connection with an electrical coaxial cable, a dielectric body 3 coaxially surrounded by the outer shell, and a conductive center contact 4 coaxially surrounded by the dielectric body and having an electrical contact portion 14 for releasable connection with the coaxial cable and an electrical terminal portion 13 for connection with an electrical circuit, characterized in that, the center contact has a portion having a roughened outer surface 18, the dielectric body engages the center contact and has a portion flowed into interlocked engagement with the roughened outer surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A method of constructing an electrical connector, wherein the connector has a conductive outer shell for releasable connection with an electrical cable, a dielectric body coaxially surrounded by the outer shell, and a conductive electrical contact coaxially surrounded by the dielectric body and having an electrical contact portion for releasable connection with the cable, comprising the steps of: assembling the contact concentrically within the dielectric body, coaxially surrounding a roughened outer surface portion of the contact with an interior surface portion of the dielectric body, heating a portion of the contact, heating the continuous interior surface portion of the dielectric body to a fluid state and into flowed interlocked engagement with the roughened surface portion, and assembling the outer shell concentrically over the dielectric body.
Claim 2
Independent Claim
125 words
A method of constructing an electrical connector, wherein the connector has a conductive outer shell for releasable connection with an electrical cable, a dielectric body coaxially surrounded by the outer shell, and a conductive electrical contact coaxially surrounded by the dielectric body and having an electrical contact portion for releasable connection with the cable, comprising the steps of: assembling the contact concentrically within the dielectric body, coaxially surrounding a roughened outer surface portion of the contact with an interior surface portion of the dielectric body, heating a portion of the contact, heating the continuous interior surface portion of the dielectric body to a fluid state and into flowed interlocked engagement with the roughened surface portion, and assembling the outer shell concentrically over the dielectric body.
Claim 3
Dependent Claim
32 words
A method for constructing an electrical connector, as recited in claim 1, wherein the step of heating the contact includes the step of, inductively heating the roughened surface portion of the contact.
Claim 4
Dependent Claim
48 words
A method for constructing an electrical connector, as recited in claim 1, and further including the steps of, assembling the contact and the roughened surface of the contact with a compression fit in an axial bore of the dielectric body prior to the step of heating the contact.
Claim 5
Dependent Claim
38 words
A method for constructing an electrical connector, as recited in claim 1, and further including the step of, locating the roughened surface portion of the contact with respect to an external, radially projecting shoulder on the dielectric body.
Claim 6
Dependent Claim
32 words
A method for constructing an electrical connector, as recited in claim 3, wherein the step of heating the contact includes the step of, inductively heating the roughened surface portion of the contact.
Claim 7
Dependent Claim
48 words
A method for constructing an electrical connector, as recited in claim 4, and further including the steps of, assembling the contact and the roughened surface of the contact with a compression fit in an axial bore of the dielectric body prior to the step of heating the contact.
Claim 8
Dependent Claim
32 words
A method for constructing an electrical connector, as recited in claim 4, wherein the step of heating the contact includes the step of, inductively heating the roughened surface portion of the contact.
