Abstract:
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.
Abstract:
In a terminal, an engaging portion for engaging the walls of an aperture formed in a housing or a printed circuit board, in which the aperture is substantially rectangular in cross-sectional area configuration. The engaging portion comprises a pair of curved, substantially parallel beams extending longitudinally through the aperture. The two beams are curved in the same direction with the two ends of the concave sides of the beams pressing against one major wall of the aperture and the center portion of the convex side of the beam pressing against the other major wall of the aperture. Further, the two beams are bowed outwardly from each other with their side edges pressing against the side walls of the aperture, thereby producing an overall force-fit effect in which the aperture engaging portion of the terminal exerts force in all four directions against the sidewalls of the aperture and is rigidly secured therein.
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 holder simultaneously operating as a bussing connector for discrete electrical circuits paths on opposed sides of a substrate. The holder is mounted on a circuit board and is provided with discrete electrical paths receiving the discrete electricaL paths of the circuit board. An elongated clamp retains the circuit paths of the holder in electrical contact with the electrical paths of the circuit board. The clamp additionally retains the holder in clamped position on the circuit board.
