摘要:
An electrical connector for the terminating edge of a printed circuit board to form the portion of the printed circuit board adapted to engage bowed portions of contact fingers in a conventional card edge connector. The finger connector insulator includes a slotted head section for receiving the board edge and a blade section for engaging a conventional card edge connector. Each side of the insulator contains a plurality of spaced contact receiving sleeves formed by parallel, transversely extending recesses which face outwardly on the blade and inwardly from each wall of the slotted head and which are connected by coaxial apertures formed in the head section.

A multiplicity of integrated circuit connector contact sockets mounted to a plurality of carrier strips are moved between pairs of orientation rollers with tails of the contacts protruding upwardly whereby an upper socket portion of one contact is aligned with an upper socket portion of a contact on a carrier strip in an adjacent row. A plurality of integrated circuit connector insulators having socket receiving apertures formed therein are held together in an array and placed over the contact tails with one tail being received within each aperture of an insulator. The carrier strips are simultaneously advanced beneath a work station wherein a tool presses the insulators downwardly to tightly fit the contact socket portions into the receiving apertures in the insulators. A shearing tool then severs the insulators in the array from one another except for the continued affixation of the contact sockets to the parallel carrier strips. The carrier strips are then moved through a stripping station comprising a block having parallel channels for receiving the carrier strips and a flat inclined upper surface wherein the carrier strips are restrained from vertical movement while the inclined ramp strips the insulator mounted contacts from the carrier strips to form completed individual connectors.

A plurality of integrated circuit lead clips having a circular top opening and four resilient planar tines are positioned in a holding fixture in a rectangular matrix array. A carrier strip including a plurality of equally spaced, transversely extending projections each having a generally rectangular cross-section is positioned above a row of clips positioned in the fixture. The strip is vibrated and then lowered to pass one projection into the top opening of each clip and through the four resilient planar tines. Vibrations of the projections at the same time the tips of the projections touch the clips causes the clip to rotate in the fixture so that the planar ends of the tines orient with respect to the four flat sides of each projection. The projections are pushed through the clips so that they are held to the projections by the resiliency of the tines. Once the clips are oriented and affixed to the projections on the carrier strip they may be installed directly into mounting apertures, such as plated holes in a printed circuit board, or inserted into oriented integrated circuit connector contacts.

Press fit contacts having upper mating portions are stamped, formed and oriented out of sheet material for simultaneous insertion and housing in a removable connector insulator. Receiving sleeves formed in the insulator are constructed to permit the contacts to be bottom loaded into the sleeves, seated and lightly held therein. Each contact includes an intermediate press fit collar portion which engages a mating shoulder in the insulator. The insulator serves as a holding fixture and seating tool for transmitting insertion force applied to the top of the insulator to each one of the contacts for press fitting them into contact receiving apertures in a mounting substrate. The contacts held by each insulator are all simultaneously press fitted into the substrate by continuing to apply pressure to the top of the insulator until it is mounted flush upon the substrate. After the connector is assembled, the contact is in a configuration for electrical engagement with a mating contact (not disclosed) while a contact tail portion may extend below the substrate for wire wrap termination. The configuration of the assembled connector permits removal of the insulator by lifting it from around the contacts, which it lightly engages, leaving the contacts rigidly mounted in the substrate. Further, a connector assembly, comprising an insulator having contacts lightly held therein, may be readily shipped to a remote location for press fit installation in a mounting substrate.
摘要:
A method and apparatus for pull fitting contacts. Contacts tails initially are placed through apertures on a mounting member. A support member having a pair of clamping jaws which clamp the contact ends encloses an actuation plate which after the tails are clamped pushes the mounting member relative to the support member thereby inserting the contacts completely into an insulative housing.

摘要:
A solderless electrical connector comprising a printed circuit board and electrical contact terminals mounted therein. A printed circuit board is fabricated to the construction stage wherein conductive circuitry interconnects plated through holes formed therethrough. The exposed circuitry and plated through holes are covered with a conformal coating of insulative material which seals the outer surfaces of the conductive materials from the environment and its effects. The insulative coating obviates the need for solder to protect the conductive materials as well as precludes the use of solder for electrical interconnection therewith. The plated through holes are constructed for press fit insertion of contact terminals in tight frictional engagement therein. The press fit insertion of a contact having an angular edge portion effectively penetrates the insulative coating by deforming it away from that portion of the plated through hole brought to bear against the contact. A mechanical and electrical interconnection is thereby provided between the plated through hole and contact terminal of the press fit assembly while the utilization of solder and the requisite heat thereof is effectively eliminated.
摘要:
Pull through contacts and receiving sleeves within a connector insulator cooperate to permit the contacts to be inserted into the sleeves of the insulator in either direction and to be held there by interference between laterally extending, coined portions on the contact of a bellows type and the walls of the sleeve. Card edge connector contacts are formed from square wire stock by coining a central portion of each contact into a press fit region and a pair of lower alignment ears. The receiving sleeves formed in the insulator are constructed to permit the contact to be initially top loaded therein and held in position within the insulator by means of engagement of the lower ears on the contact with the side walls of the sleeves. Once the connector of the present invention is assembled to a mounting substrate by pull home press fitting of the contacts, the insulator may be removed by lifting upwardly to overcome the frictional engagement between the contact ears and the side walls of the sleeves to expose the contacts free standing in the substrate for subsequent repair thereof.
