Abstract: A printed circuit board connector is comprised of an elongated rectangular housing having a passageway in a longitudinal edge thereof for insertion of the board. A thin plate lever lying along the outer surface of each side wall of the housing and rockably mounted thereon, is provided at its free end with openings to capture the free ends of resilient contact members supported within the housing for retracting them against their bias from the path of a circuit board inserted in the passageway. A thin slidable cam plate between each of the side walls and plate levers cooperates with projections on the walls for causing them to move outward for pulling the contacts away from the passageway. A feature of the invention is that the housing and plate levers are all injection molded in one piece, and the levers are broken off the housing and rockably mounted thereon.

Abstract: A circuit board connector having a plurality of pairs of contacts arranged in a row and with each contact having a "C" shaped portion. Each pair of contacts is mounted securely at first ends thereof in a circuit board with the backs, or closed sides, of the "C" shaped portion facing each other and designed to receive the edge of a second circuit board inserted therebetween. The free end of each contact has an ear-like element extending outwardly from the board to which the contacts are secured. A connector housing fits over the pairs of contacts after they have been secured in the board. Inside the housing tabs are provided, behind which tabs the ears of the contacts are positioned, thereby prestressing each pair of contacts apart. The housing is also designed so that the side walls thereof press against a dimple or finger-like tang formed near the base of each contact, thereby forcing the contacts of each pair of contacts together and further enhancing the prestressing of each pair of contacts.

Abstract: A metal clip for connecting an insulated wire and a terminal post together without stripping the wire or solder. The clip is generally channel-shaped with a first slot means extending across the bottom wall of the channel and into the side walls of the channel. Extensions of the free end of the side walls are folded within the channel back towards the bottom wall and have second slots formed therein which are aligned with the first slot means. The conductor is inserted into the first and second slots and then the terminal post is pushed into the channel at right angles to the wire and adjacent the bottom wall thereof to force the conductor farther back into the slots and causing the edges of the slots to either grip or cut through the insulation and into the wire, thereby making a good electrical and mechanical connection.

Abstract: A female contact particularly useful as a low profile contact inserted in a printed circuit board and comprising a tubular portion with a flared open end for receiving a male pin. A pair of opposing contact fingers extend from the flared open end and are folded back upon themselves to extend downwardly into the interior of the tubular portion. Near the open end of the tubular portion the two opposing fingers are initially close to, and substantially parallel to, the walls of the tubular portion. As they extend further into the tubular portion, the curved fingers extend away from the walls of the tubular portion and towards each other, with their concave surfaces facing each other. As a terminal post is initially inserted between the fingers the fingers are deflected apart and outwardly towards the walls of the tubular portion so that a point on said fingers will be forced against the wall of the tubular portion.

Abstract: An apparatus consisting of a pair of rollers with tangentially meeting perimeters for crimping successive portions of a continuous strip of solder into rings around a strip of terminal posts carried in parallel manner upon a common carrier strip. The roller perimeters each contain a circumferential track of crimping ridges which are both axially and angularly positioned to coincide with corresponding ridges on the other roller to crimp said solder strip around each post on the strip of terminal posts, both strips being simultaneously passed between the crimping tracks on said rollers. Each roller also comprises a circumferential track of spur-type gear teeth, the two tracks being axially offset on opposite sides of said crimping tracks and having bottom lands (the troughs of the teeth) which coincide when the teeth pass through the common tangential or pitch plane of the rollers.

Abstract: According to one aspect of the disclosure, a planar substrate receives a plurality of conductive posts therein, which posts include an offset medial portion having a laterally projecting notch portion. Certain posts are arranged with their notch portions in coplanar relationship and in latching registration with an interior sidewall portion of a housing received over the posts. Accordingly, the housing provides an insulating receptacle shroud for the posts and is latchingly retained in place without a need for attachment to the substrate. The shroud is also provided with card guides connected thereto by integral hinge portions enabling alignment of, and reducing twisting and warping of, the card guides. The card guides are additionally coupled together with rails further reducing twisting and warping of the guides. The terminals are advantageously mounted in strip form for ease in manufacture and assembly to the substrate.

Abstract: A low profile contact, stamped or cut from a section of flat stock material, for receiving a male pin for connection to a lead of a printed circuit board, includes a cylindrically shaped pin receiving portion for insertion into a hole in the printed circuit board conterminous with the lead. A plurality of tabs extend upwardly from the top of the cylinder, and a pair of opposite tabs are bent intermediate their ends to partially extend into the cylinder to engage the inserted pin. The tabs are flared outwardly from the top of the cylinder to provide a guide to assist insertion of the pin into the cylinder and to provide a seat upon which the contact seats upon the surface of the circuit board. The cylinder is formed with a gap or space parallel to its axis to enable it to be radially compressed upon insertion into the hole of the printed circuit board to urge or bear outwardly upon the walls of the hole to establish firm physical and electrical contact therewith.

Abstract: A tool for inserting either single loose pins or a plurality of pins or posts carried upon a mounting strip into holes of a substrate, such as a printed circuit board, in a continuous process and including a push blade and a carrier control blade for receiving the pins and the mounting strip which are carried upon a mounting frame. A plurality of ribs protrude upwardly from the push blade, forming grooves therebetween into which the pins to be aligned for insertion are positioned. A slideable, securing blade, carried upon the mounting frame, is moveable from a position away from the pins to a position engaging the pins to secure them in their aligned positions. A locking mechanism on the securing blade cooperates with the mounting frame to lock the securing blade in the engaging position.
