Abstract
Abstract A dual flat-spring electrical contact includes a contact receptacle which contains a separation gap and on which spring prongs protrude on one side while the cable connector protrudes on the other side. The contact receptacle is rigidly locked against expansion, as in the area of the separating gap, during insertion of a contact pin between the prongs because on a receptacle wall, in the area of the separating gap, there protrudes a T-shaped cover plate for which there is provided a holding recess which adjoins an adjacent contact receptacle wall.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
A dual flat-spring electrical contact, comprising (a) a hollow contact receptacle formed from a thin piece of metal bent into a generally rectangular configuration, said receptacle containing a gap between the bent edges thereof; (b) a pair of mutually opposed spring prongs extending from one end of said receptacle; and (c) latch means connected with said receptacle to prevent expansion of said receptacle upon insertion of a contact pin between said spring prongs, said latch means including (1) a latch plate extending from a top wall of said receptacle; and (b 2) said receptacle including a side wall containing a recess adapted to receive said latch plate, whereby when said latch plate is arranged within said recess, said latch plate prevents said receptacle top wall from being displaced from said side wall in the vicinity of said gap when a contact pin is inserted between said prongs.
Claim 2
Dependent Claim
147 words
A dual flat-spring electrical contact, comprising (a) a hollow contact receptacle formed from a thin piece of metal bent into a generally rectangular configuration, said receptacle containing a gap between the bent edges thereof; (b) a pair of mutually opposed spring prongs extending from one end of said receptacle; and (c) latch means connected with said receptacle to prevent expansion of said receptacle upon insertion of a contact pin between said spring prongs, said latch means including (1) a latch plate extending from a top wall of said receptacle; and (b 2) said receptacle including a side wall containing a recess adapted to receive said latch plate, whereby when said latch plate is arranged within said recess, said latch plate prevents said receptacle top wall from being displaced from said side wall in the vicinity of said gap when a contact pin is inserted between said prongs.
