Abstract
Abstract A printed circuit board connector having a plurality of contacts mounted in the connector housing and the method of assembly thereof. The contacts are formed of a spring contact portion having a contacting surface and terminal portions interconnected by a central mounting portion. The contact is inserted on a mounting member in an unstressed condition with the contacting surface extending from the mounting member in one direction and the terminal portion extending from the mounting member in an opposite direction. A connector housing member contains a slot therethrough for positioning a printed circuit board therein. The connector housing member is positioned on the mounting member. When positioned on the member, curved inner surfaces of the housing member cause the contacts to be spread apart, preloading the contacts at the tip. When the printed circuit board is inserted into the housing, the housing protects the tip member from direct contact by the printed circuit board.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
211 words
A printed circuit board connector comprising: a mounting member having a pair of rows of openings therein; a plurality of electrical contacts mounted in said openings in opposed contact pairs; the contacts of each said contact pairs having mounting portions positioned in said openings, spring portions extending upwardly at an angle from said mounting portions in a direction toward one another, oppositely bent free end sections, and transitional contacting sections joining said spring portions and said end sections; a housing member positioned over said contacts for preloading said contacts at said free end sections, said housing being formed with a pair of spaced side walls on opposite sides of said rows of contacts, said side walls having lip portions extending downwardly from the upper portions thereof terminating in edges abutting said contact free end sections, said lip portions being spaced apart to define a printed circuit board slot therebetween, said edges holding said contacts in preloaded condition for engagement with a printed circuit board inserted through said slot, said lip portions defining surfaces extending from said edges upwardly and outwardly at an angle with respect to a vertical plane passing througn said slot and at a slight acute angle with respect to the upper surfaces of said contact free end sections.

A printed circuit board connector comprising: a mounting member having a pair of rows of openings therein; a plurality of electrical contacts mounted in said openings in opposed contact pairs; the contacts of each said contact pairs having mounting portions positioned in said openings, spring portions extending upwardly at an angle from said mounting portions in a direction toward one another, oppositely bent free end sections, and transitional contacting sections joining said spring portions and said end sections; a housing member positioned over said contacts for preloading said contacts at said free end sections, said housing being formed with a pair of spaced side walls on opposite sides of said rows of contacts, said side walls having lip portions extending downwardly from the upper portions thereof terminating in edges abutting said contact free end sections, said lip portions being spaced apart to define a printed circuit board slot therebetween, said edges holding said contacts in preloaded condition for engagement with a printed circuit board inserted through said slot, said lip portions defining surfaces extending from said edges upwardly and outwardly at an angle with respect to a vertical plane passing througn said slot and at a slight acute angle with respect to the upper surfaces of said contact free end sections.
Claim 3
Dependent Claim
45 words
A connector as set forth in claim 1 wherein: said mounting member is a planar substrate; and said housing member is a hollow shell with said side walls opening at the bottom thereof to permit said shell to enclose said contacts above said planar substrate.
Claim 4
Dependent Claim
50 words
A connector as set forth in claim 2 wherein: said housing has transverse walls separating adjacent pairs of said contacts; downwardly opening slots formed in said transverse walls; and said mounting portions of said contacts including laterally extending portions above said substrate and slidably disposed in said downwardly extending slots.
