摘要:
This invention relates to a connector for electrical conductors and more particularly to a connector adapted to receive aluminum and copper conductors therein. The connector includes an elongated groove wherein the inwardly facing edges of the sidewalls defining the grooves provide a scraping action against the conductor to break up the oxide film or insulation thereon and further wherein the sidewalls are elastically flexed outwardly by the tamping of the conductor into the groove so as to maintain a continual pressure on the conductor and thereby counter creep induce by temperature change and the like.

The present invention relates to an apparatus for simultaneously assembling a plurality of elongated contacts within corresponding apertures provided in a printed circuit board. According to the of the present invention, an entire row of elongated contacts are initially manually inserted into corresponding rows of P.C. board apertures with the aid of a hand tool. In the present invention, the printed circuit board is mounted on a carriage of an insertion machine. The initially inserted row of contacts partially protrudes through the P.C. board and is received in the jaws of a vise. In the operation of the insertion machine, the vise jaws close and grip the row of protruding contacts. Sequentially, a limited and precisely adjusted relative motion is effected between the P.C. board carriage and the vise. Such operation causes a corresponding limited and precisely controlled relative displacement between the inserted row of contacts and the P.C. board, thus forcibly positioning and seating the enlarged, interference fit portions of the contacts within corresponding apertures of the P.C. board. In this manner, all contacts of the row are precisely positioned simultaneously in desired registration within the printed circuit board. Sequentially, the vise jaws are opened, allowing an operator of the machine to remove the contacts therefrom and reposition the P.C. board on the carriage for insertion of another row of contacts. With the board thus repositioned, the machine may be reset for a repeated cycle of operation. In a modification of the machine, a mechanism is provided which is actuated after opening of the jaws, thereby automatically removing the row of contacts from the jaws. The purpose of this operation is to provide a substantial clearance between the P.C. board and the jaws, allowing the operator to reposition the P.C. board on the carriage without interfering with the vise jaws. With the P.C. board repositioned (desirably for insertion of another row of contacts) the operator may then reset the machine for a repeated cycle of operation.

A device providing spark gaps protection between the pins of a cathode ray tube and solid state circuitry associated therewith is disclosed. The device includes an insulated substrate, a metallic layer on the substrate and a grounding strap. The device is mounted on the base of a cathode ray tube with projections on the metallic layer extending to within a predetermined distance from the pins providing a spark gap therebetween.

Apparatus for connecting the corresponding terminals in two identical two-row electrical connectors comprises connector jig for locating the connectors in back-to-back relationship with the corresponding ends of the connectors proximate to each other but with the corresponding rows of terminals offset from each other. In use, the ends of wires are first connected to one row of terminals in each connector, the row in each connector being noncorresponding to the row in the other connector. The connectors are then placed in the jig and the wires are laced diagonally from each connector to the other connector and into alignment with the corresponding terminals of the other connector. The apparatus includes means for shearing the wires thus laced and inserting the trimmed wires into the terminals in the other connector.

Loading coil assembly for a multi-conductor assembly comprises a plurality of spaced-apart trays positioned on the cable and coil housings mounted between the trays. Each coil housing contains a plurality of loading coils. The conductors from the cable extend between the trays and to a connecting means on the housing which connects the cable conductors to the leads from the coils.

A connector for connecting external circuitry to terminal pads of a thin plate-like sub-strate comprises a generally prismatic housing having terminals extending therethrough from one face to the other face. The one face has a centrally located substrate receiving zone thereon and the terminals, which extend along opposite sides of the zone, have resilient cantilever arms which contact the pads. The substrate is held in the zone by securing means on the housing.

A connector post or pin is disclosed which is particularly suitable for use with printed circuit board assemblies. The post includes a coined portion which is designed to permit the pin to be easily inserted into holes of a predetermined size in printed circuit boards, and to increase the quality of a solder joint between the post and the printed circuit board. A solder stripe is placed on each post in the coined region to facilitate soldering of the posts to conductive portions of the printed circuit board. The posts are attached in groups to break-away carrier strips to aid in the rapid assembly of large numbers of posts to printed circuit boards. The posts may also include provisions for coupling them to multilayered printed circuit assemblies. A method of fabricating the coined post is also disclosed which converts a post with normally an interference fit in a printed circuit board aperture to a post which is freely received in the aperture together with masses of solder adhered to said post.

An improved insulation piercing contact and connector is disclosed which contact strips the insulation from at least two sides of a conductor when making the insulation piercing contact. The subject contact includes a cylindrical member having a sharp annular edge and a pin member of wedge shaped configuration with at least one transverse step formed in the inclined surface of the pin. A conductor inserted into the cylindrical member is pinched between the cylindrical wall and the pin member with the insulation being stripped from the conductor by the annular edge of the cylindrical member and the step in the pin member.
