Abstract
Abstract A coaxial contact for termination to printed circuit boards and the like includes an assembly featuring a dielectric insulator disposed within an outer contact. An outer tail is disposed within the outer contact and an inner tail is disposed within the insulator. The outer contact is staked to retain the outer tail within said contact, and to compress the insulator between the inner tail and the outer contact to retain the inner tail and the insulator within the assembly and to prevent leakage. Alternatively, adhesive joints may be used to retain the insulator within the outer assembly and the inner tail within the insulator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
244 words
A coaxial contact for termination to printed circuit boards and the like, comprising: an outer contact having a bore; a dielectric insulator concentrically disposed within the outer contact, and having an aperture; an outer contact tail having a first portion which is disposed in the bore of the outer contact and a second portion extending external thereto for termination to the printed circuit board and the like; an inner contact tail having a first portion which is disposed in the aperture of the insulator and a second portion extending external of the insulator and the outer contact for termination to the printed circuit board and the like; means for retaining the first portion of the outer contact tail within the outer contact bore; and means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator wherein the means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator includes: the outer contact having an undercut; the first portion of the inner contact tail having an undercut within the undercut of the outer contact; and a stake within the outer contact undercut, said stake being effective for compressing the insulator between the first portion of the inner contact tail and the outer contact to retain the insulator within the outer contact and to retain the inner contact tail within the insulator.
Claim 2
Dependent Claim
244 words
A coaxial contact for termination to printed circuit boards and the like, comprising: an outer contact having a bore; a dielectric insulator concentrically disposed within the outer contact, and having an aperture; an outer contact tail having a first portion which is disposed in the bore of the outer contact and a second portion extending external thereto for termination to the printed circuit board and the like; an inner contact tail having a first portion which is disposed in the aperture of the insulator and a second portion extending external of the insulator and the outer contact for termination to the printed circuit board and the like; means for retaining the first portion of the outer contact tail within the outer contact bore; and means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator wherein the means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator includes: the outer contact having an undercut; the first portion of the inner contact tail having an undercut within the undercut of the outer contact; and a stake within the outer contact undercut, said stake being effective for compressing the insulator between the first portion of the inner contact tail and the outer contact to retain the insulator within the outer contact and to retain the inner contact tail within the insulator.
Claim 3
Dependent Claim
288 words
A coaxial contact for termination to printed circuit boards and the like, comprising: an outer contact having a bore; a dielectric insulator concentrically disposed within the outer contact, and having an aperture; an outer contact tail having a first portion which is disposed in the bore of the outer contact and a second portion extending external thereto for termination to the printed circuit board and the like; an inner contact tail having a first portion which is disposed in the aperture of the insulator and a second portion extending external of the insulator and the outer contact for termination to the printed circuit board and the like; means for retaining the first portion of the outer contact tail within the outer contact bore; and means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator wherein the means for retaining the first portion of the outer contact tail within the outer contact bore includes: a stake on the outer contact, said stake being effective for retaining the first portion of the outer contact tail within the outer contact, and wherein the means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator includes: the outer contact having an undercut; the first portion of the inner contact tail having an undercut within the undercut of the outer contact; and a stake within the outer contact undercut, said stake being effective for compressing the insulator between the first portion of the inner contact tail and the outer contact to retain the insulator within the outer contact and to retain the inner contact tail within the insulator.
Claim 4
Dependent Claim
288 words
A coaxial contact for termination to printed circuit boards and the like, comprising: an outer contact having a bore; a dielectric insulator concentrically disposed within the outer contact, and having an aperture; an outer contact tail having a first portion which is disposed in the bore of the outer contact and a second portion extending external thereto for termination to the printed circuit board and the like; an inner contact tail having a first portion which is disposed in the aperture of the insulator and a second portion extending external of the insulator and the outer contact for termination to the printed circuit board and the like; means for retaining the first portion of the outer contact tail within the outer contact bore; and means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator wherein the means for retaining the first portion of the outer contact tail within the outer contact bore includes: a stake on the outer contact, said stake being effective for retaining the first portion of the outer contact tail within the outer contact, and wherein the means for retaining the insulator within the outer contact, and for retaining the first portion of the inner contact tail within the insulator includes: the outer contact having an undercut; the first portion of the inner contact tail having an undercut within the undercut of the outer contact; and a stake within the outer contact undercut, said stake being effective for compressing the insulator between the first portion of the inner contact tail and the outer contact to retain the insulator within the outer contact and to retain the inner contact tail within the insulator.
Claim 5
Dependent Claim
43 words
A coaxial contact as described by claim 2, wherein: the first portion of the inner contact tail which is disposed in the aperture of the insulator is axially offset from the second portion thereof extending external of the insulator and the outer contact.
