Abstract
Abstract A card-edge connector assembly (30) for releasably securing a circuit board (13) having an elongated insulative housing (32) formed of a moldable material and defining an elongated channel (40) in a surface (38) of the housing (32). Integrally formed latches (36, 36'), disposed on opposite ends of the elongated channel, include latch lever portions (44, 44') extending upwardly and rearwardly therefrom to facilitate access to the latches (36, 36'). Backstops (42, 42') are integrally formed with the housing and extend outwardly from the housing surface to positions vertically below the latch levers, respectively. A slot (64, 64') is formed between the backstop and the latch members. Each latch lever defines a central mold opening (46, 46') extending therethrough and positioned in vertical alignment with the corresponding backstops. Each mold opening is sufficiently large to permit withdrawal of a slot defining-mold component (74) along a linear path away from the slots therethrough during integral molding of the connector assembly. The mold opening is further sufficiently small to provide substantial area on the latch lever portion to enable manual release of the latch members.

Claim 1
Independent Claim
347 words
A card-edge connector assembly for releasably securing a circuit board having a front edge and opposite side edges, said connector assembly comprising: an elongated electrically insulative housing formed of a moldable material and defining an elongated channel in a surface of said housing and formed to receive the front edge of the circuit board; a first latch member and a second latch member positioned proximate opposite ends of said channel and integrally formed with said housing; said first latch member and said second latch member each including, a body portion extending outwardly from said surface, detent means extending outwardly from an upper end of said body portion for engaging said respective side edges of said circuit board, and a latch lever inclined angularly upwardly and outwardly from said upper end of said body portion; a first backstop member and a second backstop member disposed proximate said first latch member and said second latch member, respectively, each backstop member being integrally formed with said housing and extending outwardly from said surface of said housing to positions substantially vertically below said latch lever and outwardly of said first latch member and said second latch member; said first backstop member and said second backstop member defining with said first latch member and said second latch member slots permitting limited deflection of said first latch member and said second latch member in a direction toward said first backstop member and said second backstop member, respectively; and said latch lever of each of said first latch member and said second latch member defining a central mold opening extending therethrough and positioned in vertical alignment with each of said first backstop member and said second backstop member, each said mold opening being sufficiently large to permit withdrawal of a slot defining-mold component along a substantially linear path away from said slots extending through said mold opening during integral molding of said latch members and said backstop members with said housing, and said opening being sufficiently small to provide substantial area on said latch lever portion to enable manual release of said latch members.
Claim 2
Dependent Claim
347 words
A card-edge connector assembly for releasably securing a circuit board having a front edge and opposite side edges, said connector assembly comprising: an elongated electrically insulative housing formed of a moldable material and defining an elongated channel in a surface of said housing and formed to receive the front edge of the circuit board; a first latch member and a second latch member positioned proximate opposite ends of said channel and integrally formed with said housing; said first latch member and said second latch member each including, a body portion extending outwardly from said surface, detent means extending outwardly from an upper end of said body portion for engaging said respective side edges of said circuit board, and a latch lever inclined angularly upwardly and outwardly from said upper end of said body portion; a first backstop member and a second backstop member disposed proximate said first latch member and said second latch member, respectively, each backstop member being integrally formed with said housing and extending outwardly from said surface of said housing to positions substantially vertically below said latch lever and outwardly of said first latch member and said second latch member; said first backstop member and said second backstop member defining with said first latch member and said second latch member slots permitting limited deflection of said first latch member and said second latch member in a direction toward said first backstop member and said second backstop member, respectively; and said latch lever of each of said first latch member and said second latch member defining a central mold opening extending therethrough and positioned in vertical alignment with each of said first backstop member and said second backstop member, each said mold opening being sufficiently large to permit withdrawal of a slot defining-mold component along a substantially linear path away from said slots extending through said mold opening during integral molding of said latch members and said backstop members with said housing, and said opening being sufficiently small to provide substantial area on said latch lever portion to enable manual release of said latch members.
Claim 3
Dependent Claim
35 words
The card-edge connector as defined in claim 1 wherein, each said backstop member includes opposite side walls tapering inwardly from an upper portion of said backstop member to a lower portion of said backstop member.
Claim 4
Dependent Claim
24 words
The card-edge connector as defined in claim 1 wherein, said slot defining-mold component further defines a backstop top surface of each said backstop members.
Claim 5
