Abstract
Abstract A printed circuit board connector utilizing a rotatable cam having spring contacts molded therein, the cam being positioned within a channel which is aligned with and substantially parallel to a rectangular slot also located within the connector. Upon insertion of the circuit board into the rectangular slot, the cam is rotated, thus providing electrical contact between specific areas on the circuit board and corresponding contacting areas of terminal members located within the channel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
A printed circuit board connector comprising: an insulating body of predetermined length, said insulating body having a rectangular slot located therein for receiving said printed circuit board, and a channel having two opposing end portions and a substantially larger center portion substantially parallel to and aligned with said rectangular slot; a plurality of terminal members, each of said members having an electrical contacting portion located within said larger center portion of said channel of said insulating body and an elongated portion protruding from said insulating body; an insulative cam positioned within said channel of said insulating body and formed to at least partially rotate within said channel; a plurality of individual resilient contact means positioned spacedly upon said insulative cam, said contact means to provide electrical contact between said electrical contacting portions of said terminal members and corresponding areas of said printed circuit board; and means for retaining said insulative cam adapted to fit within said opposing end portions of said channel of said insulating body.
Claim 2
Dependent Claim
166 words
A printed circuit board connector comprising: an insulating body of predetermined length, said insulating body having a rectangular slot located therein for receiving said printed circuit board, and a channel having two opposing end portions and a substantially larger center portion substantially parallel to and aligned with said rectangular slot; a plurality of terminal members, each of said members having an electrical contacting portion located within said larger center portion of said channel of said insulating body and an elongated portion protruding from said insulating body; an insulative cam positioned within said channel of said insulating body and formed to at least partially rotate within said channel; a plurality of individual resilient contact means positioned spacedly upon said insulative cam, said contact means to provide electrical contact between said electrical contacting portions of said terminal members and corresponding areas of said printed circuit board; and means for retaining said insulative cam adapted to fit within said opposing end portions of said channel of said insulating body.
Claim 3
Dependent Claim
51 words
The printed circuit board connector according to claim 1 in which said resilient contact means consist of a plurality of formed spring members, each having a substantially straight central portion affixed within said insulative cam and having projecting end contacting portions angularly bent to extend from said cam in opposing directions.
Claim 4
Dependent Claim
18 words
The printed circuit board connector according to claim 2 in which said formed spring members are sUbstantially S-shaped.
Claim 5
Dependent Claim
46 words
The printed circuit board connector according to claim 1 in which said means for retaining said insulative cam within said opposing end portions of said channel consist of a plurality of boxlike plugs positioned atop said cam and within said opposing end portions of said channel.
Claim 6
Dependent Claim
23 words
The printed circuit board connector according to claim 4 in which each of said boxlike plugs is provided with a protruding rib member.
Claim 7
Dependent Claim
47 words
The printed circuit board connector according to claim 5 in which said insulative cam is provided with a plurality of indented grooves to mate with said protruding rib members of said boxlike plugs, said protruding rib members thereby restricting the amount of rotational movement of said cam.
Claim 8
Dependent Claim
42 words
The printed circuit board connector according to claim 1 in which said insulative cam has an end portion, said end portion extending from said insulative body and incorporating means to facilitate movement of said cam after insertion of said printed circuit board.
Claim 9
Dependent Claim
39 words
The printed circuit board connector according to claim 7 in which said means to facilitate movement of said cam after insertion of said printed circuit board consists of an extending rectangular body formed to accept a corresponding tool member.
Claim 10
Dependent Claim
31 words
The printed circuit board connector according to claim 7 in which said means to facilitate movement of said cam after insertion of said printed circuit board consists of a dial member.
