  • Patent number: 4381134
    Abstract: An electrical connector (20) adapted for engagement with a plated-through hole (13) in a printed circuit board (10) is disclosed. This connector includes first and second generally squared-shaped posts (21,22) for receiving electrically conductive elements. Intermediate these first and second posts is a compliant section (23,24,25,26) for producing an interference coupling between the connector and the plated-through hole. Juxtaposed the compliant section and intermediate and located between it and the first post is a broaching section (30) for conditioning the plated-through hole prior to engagement of the compliant section with the plated-through hole.

  • Patent number: 4361721
    Abstract: A sealing grommet (40), used in cable splice cases (10) for connecting multiconductor telecommunication cables (100, 120), comprises a unitary elastomeric body with cable receiving passageways (50, 70). Each passageway is defined by an interior sidewall (52, 72) from which a plurality of longitudinally spaced circumferential ridges (54, 74) extend. For a substantial portion of its circumference, each ridge has an axis of projection (60, 82) which forms an oblique angle (.alpha., .beta.) with respect to the axis (58, 80) of the passageway and is sufficiently elongated in longitudinal cross section so as to be capable of flexing with respect to the axis of projection during cable insertion and enlarging its opening diameter (D.sub.R, D.sub.SR) to accommodate and form a radial seal about a cable being inserted.

  • Patent number: 4340268
    Abstract: A sneak current protector module (10) is disclosed. This module is comprised of an insulative base (11), slotted beam electrical contact pairs (31), fuse elements (51) and fuse mounting members (71). The insulative base includes a plurality of apertures (13) for holding the contact pairs. Slidably affixed to oppositely disposed edges of the insulative base are the fuse mounting members. These mounting members contain a plurality of well-like cavities (73), for holding the fuse elements. Opposite ends (55,56) of the fuse elements are electrically coupled to electrically isolated contacts (33) in different ones of the contact pairs.

  • Patent number: 4333700
    Abstract: A slotted beam contact element (10, 110), which can penetrate insulation (224) surrounding a conductor (202), includes cutting edges (44, 136) and snagging surfaces (42, 134) disposed along a substantially V-shaped entrance (18, 118) to a wire-gripping slot (20, 120) at a location remote from a mouth (32, 128) to the wire-gripping slot. The cutting edges and snagging surfaces are capable of removing outer portions (229) of the insulation so that insulation-penetrating means (56, 127) in the region of the wire-gripping slot can penetrate the remaining insulation to establish electrical contact between the conductor and the contact element.

  • Patent number: 4323206
    Abstract: Apparatus (10) is disclosed for mounting a reel (40) having a material (41) wound thereon. The apparatus includes a rigid support member (20) and a first projection (21) extending generally perpendicularly from the support member for holding the reel. Extending outwardly from the support member is a second projection (22) which is spaced apart from the first projection. Fastened to this second projection and coupled about an edge of the reel of the first projection are means (60, 61, 62, 63, 64, 65) for providing a braking action to the reel as material is drawn therefrom.

  • Patent number: 4319939
    Abstract: Disclosed is a method for making an electrical cable (10) which includes a plurality of insulated conductors (11) bound together in close proximity to one another to form a cablecore. A sheet of insulative material (13) surrounds this cable core and this assembly in turn is further surrounded with a conductive shield (14). An insulative sheath (16) surrounds the entire assembly. Integral with the conductive shield are means (15) for providing shield continuity when the insulative sheath and conductive shield are entered.

  • Patent number: 3974556
    Abstract: A tool for extracting an integrated circuit package from a circuit board is disclosed. The tool has provision for converting a user applied compressive force into two components. One component actuates apparatus for grasping the underside of the circuit package while the other component produces a nearly uniform perpendicular force on apparatus which straddles the circuit package to effect the extraction.
