Abstract
Abstract A solderless connector device for engaging pins which are symetrically arranged in a grid network on a printed wiring board (hereinafter P.W. board). The P.W. board includes a center pin and surrounding pins which are symetrically arranged around each center pin. The device has an opening running from the top to the bottom and a first end having an annular pins engagement means for spreading apart the surrounding pins about the center pin, creating and maintaining a gas-tight intimate seal between the surrounding pins and the body, and fierecely gripping the surrounding pins for discouraging removal of the body from the P.W. board.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
196 words
A solderless connector device for engaging pins arranged in a grid on P.W. board, the P.W. board having a center pin and an inner set and an outer set of surrounding pins, said sets being arranged symmetrically about the center pin, the device comprising: a turret-like body having a first end and a second end and an opening extending through the first end to the second end, the opening in the first end configured for surrounding and isolating a center pin, the first end including an annular pins engagement means for spreading, gripping and creating a gas-tight seal with the surrounding pins, said engagement means comprising: a rigid ring terminating at a sharply beveled outer edge defining an annular barb for displacing the surface of an inner set of surrounding pins, and: a second, larger diameter ring having a plurality of symmetrically arranged notches which correspond to the symmetrical arrangement of an inner set of surrounding pins and are adapted for registry with the inner set of surrounding pins, said second, larger diameter ring terminating at a sharply beveled outer edge defining an annular barb for displacing the surface of an outer set of surrounding pins.
Claim 2
Dependent Claim
196 words
A solderless connector device for engaging pins arranged in a grid on P.W. board, the P.W. board having a center pin and an inner set and an outer set of surrounding pins, said sets being arranged symmetrically about the center pin, the device comprising: a turret-like body having a first end and a second end and an opening extending through the first end to the second end, the opening in the first end configured for surrounding and isolating a center pin, the first end including an annular pins engagement means for spreading, gripping and creating a gas-tight seal with the surrounding pins, said engagement means comprising: a rigid ring terminating at a sharply beveled outer edge defining an annular barb for displacing the surface of an inner set of surrounding pins, and: a second, larger diameter ring having a plurality of symmetrically arranged notches which correspond to the symmetrical arrangement of an inner set of surrounding pins and are adapted for registry with the inner set of surrounding pins, said second, larger diameter ring terminating at a sharply beveled outer edge defining an annular barb for displacing the surface of an outer set of surrounding pins.
Claim 3
Dependent Claim
43 words
The device as set forth in claim 1 wherein the second larger ring is located at the terminus of the first end, and wherein the second ring includes a flat bottomed face for flush, continuous contact of the body with a P.W. board.
Claim 4
Dependent Claim
35 words
The device set forth in claim 2 wherein the engagement means is made from a material which is harder than surrounding pins, thereby allowing increased surface displacement of such surrounding pins with the engagement means.
Claim 5
Dependent Claim
18 words
The device as set forth in claim 3 wherein the engagement means is made from heat-treated beryllium copper.
