Abstract
Abstract A coaxial pin array connector comprises a top member having guide holes corresponding to coaxial cables, and an intermediate, conductive member having throughholes, respectively corresponding to and aligned with the guide holes. A bottom, insulative member is provided having first throughholes for admitting signal pins of a circuit board and second throughholes for admitting grounding pins of the circuit board and recesses for receiving power pins of the circuit board. Conductive cylindrical hollow structures are respectively positioned in the throughholes of the intermediate member and extend between the top and bottom members to allow the coaxial cable pins to be admitted from the guide holes to the bottom member and make electrical contact with the signal pins. Each of the hollow structures has inwardly bent contacts for making pressure contact with the pin of a corresponding coaxial cable and an outwardly bent contact forming a pair of contacts with the outwardly bent contact of an adjacent hollow structure so that one of the grounding pins engages between the paired contacts when inserted through one of the second throughholes of the bottom member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
A coaxial pin array connector for connecting a plurality of pins of coaxial cables to a plurality of corresponding pins of a circuit board, said pins of the circuit board having equal lengths, comprising: a first member having a plurality of throughholes corresponding to said coaxial cables; a second, insulative member spaced from said first member, said second member having a plurality of first throughholes corresponding to said signal pins, a plurality of second throughholes for admitting grounding pins of said circuit board and a plurality of recesses for receiving power pins of said circuit board; and a plurality of electrically conductive cylindrical hollow structures respectively positioned in the throughholes of said first member and extending to said second member to allow said pins of said coaxial cables to respectively extend through said hollow structures into electrical contact with said signal pins respectively, each of said hollow structures having inwardly bent contact portions for making pressure contact with the pin of a corresponding one of said coaxial cables and an outwardly bent contact portion for forming a pair of contacts with an outwardly bent contact portion of an adjacent hollow structure so that each of said grounding pins is inserted through a corresponding one of said second throughholes of said second member and engages between said paired contacts.
Claim 2
Dependent Claim
218 words
A coaxial pin array connector for connecting a plurality of pins of coaxial cables to a plurality of corresponding pins of a circuit board, said pins of the circuit board having equal lengths, comprising: a first member having a plurality of throughholes corresponding to said coaxial cables; a second, insulative member spaced from said first member, said second member having a plurality of first throughholes corresponding to said signal pins, a plurality of second throughholes for admitting grounding pins of said circuit board and a plurality of recesses for receiving power pins of said circuit board; and a plurality of electrically conductive cylindrical hollow structures respectively positioned in the throughholes of said first member and extending to said second member to allow said pins of said coaxial cables to respectively extend through said hollow structures into electrical contact with said signal pins respectively, each of said hollow structures having inwardly bent contact portions for making pressure contact with the pin of a corresponding one of said coaxial cables and an outwardly bent contact portion for forming a pair of contacts with an outwardly bent contact portion of an adjacent hollow structure so that each of said grounding pins is inserted through a corresponding one of said second throughholes of said second member and engages between said paired contacts.
Claim 3
Dependent Claim
78 words
A coaxial pin array connector as claimed in claim 1, wherein said second member is formed with a plurality of first juxtaposed projections through which said throughholes of said second member respectively extend and a plurality of second juxtaposed projections in which said recesses are respectively formed, and wherein each of said first juxtaposed projections is disposed between said contacts of each pair to define the spacing therebetween before a grounding pin is inserted through said paired contacts.
Claim 4
Dependent Claim
31 words
A coaxial pin array connector as claimed in claim 1, wherein each of said cylindrical structures is formed of a cutout from a metal blank sheet and rolled into a cylinder.
Claim 5
Dependent Claim
21 words
A coaxial pin array connector as claimed in claim 1, wherein said first member is formed of an electrically conductive material.
Claim 6
Dependent Claim
59 words
A coaxial pin array connector as claimed in claim 4, further comprising a third member of insulative material having a plurality of guide holes corresponding to said coaxial cables and aligned respectively with the throughholes of said first member to allow the pins of said coaxial cables to be inserted through said guide holes into said cylindrical hollow structures.
Claim 7
Dependent Claim
52 words
A coaxial pin array connector as claimed in claim 1, wherein said first member is formed with one or more notches adjacent the circumference of each of the throughholes thereof, and each of said hollow cylindrical structures is formed with one or more projections for engaging with said one or more notches.
Claim 8
Dependent Claim
87 words
A coaxial pin array connector as claimed in claim 6, wherein each of said hollow cylindrical structures is formed with a plurality of resilient portions outwardly bent from the circumference thereof, said outwardly bent resilient portions being flexible enough to be bent inwardly to allow said cylindrical hollow structure to be forced through a corresponding one of said throughholes of said first member and spring back to original positions to hold said structure in position when said projections of the cylindrical structure are engaged with said notches.
