Abstract
Abstract A coaxial connector 10 includes a conector body (21) and a plurality of grounding pin contacts (25, 25) extending from the connector body (21) to be extended into and through a plurality of apertures (32, 32) in a printed circuit board (12) to electrically and mechanically connect the connector (10) to the board (12). The grounding pin contacts (25, 25) have a length greater than the thickness of the board (12) and include first compliant pin contact portions adapted to be positioned within the apertures (32, 32) to frictionally engage the sidewalls of the apertures (32, 32) to frictionally retain the connector (10) to the board (12) and to electrically connect the connector (10) to the board (12), and second compliant pin contact portions (51, 51) which extend out of the apertures (32, 32) beyond the opposite side of the board (12) and which, upon, passing through the apertures (32, 32) expand to a diameter greater than that of the apertures (32, 32) to mechanically lock the connector to the board. The grounding pin contacts (25, 25) are formed integral with grounding pin contact means which is mounted to the outer shell (21) of the connector (10) after the compliant portions (51, 51) of the grounding pin contacts (25, 25) are formed to simplify manufacturing procedures and permit use of different materials for the grounding pin contacts (25, 25) and the outer shell (21).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
157 words
In an electrical connector for mounting on a printed circuit board and for connection to conductive coatings of the printed circuit board in apertures extending through the printed circuit board, the connector comprising, a conductive shell encircling an insulative body, a conductive contact having a portion surrounded by the insulative body, and having a portion projecting outwardly from the shell, and conductive further electrical contacts integral with a conductive corresponding strip and projecting from an edge of the corresponding strip parallel to a thickness of the corresponding strip for insertion into corresponding apertures, the improvement comprising; the further electrical contacts extend from an edge of the corresponding strip perpendicular to a length of the corresponding strip, the length of the corresponding strip is transverse to the axis of the shell, a conductive ring overlaps the length of the corresponding strip, and the length of the corresponding strip is overlapped by and between the shell and the ring.
Claim 2
Dependent Claim
157 words
In an electrical connector for mounting on a printed circuit board and for connection to conductive coatings of the printed circuit board in apertures extending through the printed circuit board, the connector comprising, a conductive shell encircling an insulative body, a conductive contact having a portion surrounded by the insulative body, and having a portion projecting outwardly from the shell, and conductive further electrical contacts integral with a conductive corresponding strip and projecting from an edge of the corresponding strip parallel to a thickness of the corresponding strip for insertion into corresponding apertures, the improvement comprising; the further electrical contacts extend from an edge of the corresponding strip perpendicular to a length of the corresponding strip, the length of the corresponding strip is transverse to the axis of the shell, a conductive ring overlaps the length of the corresponding strip, and the length of the corresponding strip is overlapped by and between the shell and the ring.
Claim 3
Dependent Claim
53 words
In an electrical connector as recited in claim 1, the improvement further comprising; an edge of the corresponding strip extends lengthwise of the corresponding strip along the thickness of the strip, and extends transverse to the lengths of the further electrical contacts, and provides a tool bearing surface projecting outwardly from the shell.
Claim 4
Dependent Claim
45 words
In an electrical connector as recited in claim 1, the improvement further comprising; the corresponding strip and further contacts are fabricated from a material with spring properties, and the shell is fabricated from a material with lesser spring properties than that of the corresponding strip.
Claim 5
Dependent Claim
25 words
In an electrical connector as recited in claim 3, the improvement further comprising; the shell is concentrically encircled by the corresponding strip and the ring.
Claim 6
Dependent Claim
72 words
In an electrical connector as recited in claim 3, the improvement further comprising; each said further electrical contact having a free end and a portion of its length divided by a shear into a pair of separate contact sections elongated lengthwise of said contact and having separate tip ends at the free end, and each said contact section being bowed in a direction transverse to a corresponding other of said contact sections.
Claim 7
Dependent Claim
53 words
In an electrical connector as recited in claim 3, the improvement further comprising; an edge of the corresponding strip extends lengthwise of the corresponding strip along the thickness of the strip, and extends transverse to the lengths of the further electrical contacts, and provides a tool bearing surface projecting outwardly from the shell.
Claim 8
Dependent Claim
67 words
In an electrical connector as recited in claim 3, the improvement further comprising; alignment means for positioning the corresponding strip on the shell including rib means projecting from the shell and slot means in the corresponding strip for locked engagement with the rib means, and the rib means overlaps the thickness of the corresponding strip and provides a bearing surface against the thickness of the corresponding strip.
Claim 9
Dependent Claim
25 words
In an electrical connector as recited in claim 7, the improvement further comprising; the shell is concentrically encircled by the corresponding strip and the ring.
Claim 10
Dependent Claim
