Abstract
Abstract A printed circuit board connector having a plurality of contacts mounted in the connector housing. The contacts are formed of a spring contact portion having a contacting surface and a terminal portion interconnected by a central mounting portion. The contact is inserted in the housing in an unstressed condition and abuts a housing inner wall member upon partial insertion, the contact being positioned adjacent the inner wall member upon full insertion into the housing with a portion of the contact abutting the inner wall member. The contact surface of the contact is normally adjacent the top end of the housing, remote from the contact portion adjacent the inner wall member. Moreover, the inner wall member may define an edge against which the printed circuit board engages to limit its movement upon insertion of the board into the housing. The contact mounting portion may be provided with means for engaging the housing so as to correctly position the contact in the housing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A printed circuit board connector formed of a housing having a top end and a bottom end having a plurality of electrical contacts mounted therein, said housing having openings into which said contacts are inserted and an inner wall member formed in said housing intermediate said housing ends; each of said contacts being formed of a spring contact portion and a terminal portion interconnected by a central mounting portion, said contacts upon partial insertion contacting said housing inner wall member, and said contacts upon full insertion into said housing contacting an edge of said inner wall member to pre-load said contacts; and each of said spring contact portions having a shank portion curved along a radius in a first direction and a contacting surface portion extending from said shank portion and curved along a radius in a second direction with the junction of said curved portions being tangential, said contacts being fully inserted in said housing and having said shank portion contacting said edge of said inner wall member, said edge being defined by a pair of perpendicular surfaces and forming a contact pre-loading point.
Claim 2
Dependent Claim
185 words
A printed circuit board connector formed of a housing having a top end and a bottom end having a plurality of electrical contacts mounted therein, said housing having openings into which said contacts are inserted and an inner wall member formed in said housing intermediate said housing ends; each of said contacts being formed of a spring contact portion and a terminal portion interconnected by a central mounting portion, said contacts upon partial insertion contacting said housing inner wall member, and said contacts upon full insertion into said housing contacting an edge of said inner wall member to pre-load said contacts; and each of said spring contact portions having a shank portion curved along a radius in a first direction and a contacting surface portion extending from said shank portion and curved along a radius in a second direction with the junction of said curved portions being tangential, said contacts being fully inserted in said housing and having said shank portion contacting said edge of said inner wall member, said edge being defined by a pair of perpendicular surfaces and forming a contact pre-loading point.
Claim 3
Dependent Claim
45 words
A printed circuit board connector in accordance with claim 1 wherein when each of said contacts is fully inserted in said housing the contacting surface portion of said contact is positioned adjacent the top end of the housing and remote from said contact pre-loading point.
Claim 4
Dependent Claim
35 words
A printed circuit board connector in accordance with claim 2 wherein the spring contact portion of each of said contacts between the inner wall member and the top end of the housing is free standing.
Claim 5
Dependent Claim
37 words
A printed circuit board connector in accordance with claim 1 wherein said inner wall member defines a surface against which a printed circuit board engages to limit its movement upon insertion of the board into the housing.
