Abstract:
A sealed terminal block assembly (10) includes a harness assembly (78) having first electrical terminal members (30) terminated to wires (74) of a cable (72); a housing (12) molded around the harness assembly (78), with each first terminal member (30) associated with a cavity (18) of the housing; second terminal members (46) for electrically engaging a corresponding first terminal member (30) upon insertion of the second terminal member into cavity (18); and an actuator member for moving each second terminal member (46) into electrical engagement with a second wire (80) inserted into the first terminal member (30) from a wire receiving face (26) of the housing (12).
Abstract:
A cable splice enclosure (10) including a pair of cover members (12,14) joined along a flexible hinge (62,64) and rotatable together about the hinge to enclose a cable splice (150) and secure to each other with latches along both side edges (16,18;92,94). Sealant material (120) disposed within central regions (32,34) of both covers environmentally seals the surfaces of the splice connection (154,158,160) upon full closure. Embossments (44,46) on both sides of the cable-receiving channels (20,22) in associated pairs (40,42,48) proximate the cable exits include resilient flange portions (52,54) cooperate to press into the cable insulation upon full closure to define a strain relief.
Abstract:
An enclosure for terminal blocks for interconnecting conductors of multiconductor cables includes provision for two or more terminal block modules. A lid is pivotably hinged to a box-like base section, by dowels trapped in slots of hinge hooks by free ends of latch arms, with both hinge hooks and latch arms molded integrally to the rear wall of the base section. A single-piece molded clip is also defined by the hook and latch arm joined to a common base section.
Abstract:
An enclosure (10) for terminal blocks for connection of telephone service cables to others thereof or to a distribution cable (16) providing for mounting therewithin of different types of terminal block. A lid (12) is pivotable from a closed position to a first fully open position where it retains itself open, and may be further pivotable beyond the first open position to a second fully open position where it similarly retains itself open. At least two tab sections (80) of the lid's rear wall (40) have free ends (82) that abut the enclosure's rear wall when the lid is pivoted open. Corners (84, 85) of the tab free ends (82) compressively bear against the enclosure's rear wall and serve as detents to inhibit unintentional lid rotation out of either fully open position.
Abstract:
An electrical connector (10) including a housing (12) with a pair of housing sections (14) each containing a terminal (40) rotatable therewithin upon actuation to terminate an end of a wire (26,28) inserted into an aperture (22,24) thereof. For small diameter wires, a wiring indicator (60) of transparent material is affixed to the opposed side of the housing and includes a chamber (70) for each wire to be extended therethrough for termination, thus enabling visual verification that a wire end has been fully inserted. A wire retainer (90,100) is used to prevent inadvertent backout after full wire insertion but before termination. Wire retainer (100) can be a clip mountable outside the housing, and wire retainer (90) can be contained in the wiring indicator includes a spring arm (92) biasing against the wire free end (52) upon full insertion.
Abstract:
A durable, economical, and aesthetically pleasing terminal enclosure (2) for housing standardized terminal blocks (50). The terminal enclosure (2) includes a base section (30) formed as an open-faced trough with integral perpendicular end panels (24, 34). The terminal enclosure (2) also has a pair of gull-wing doors (10, 20) which may be closed to cover the base section (30). The doors (10, 20) are formed with a curvature to provide a continuous arching cover over the base section (30), and a plurality of legs (12-1 . . . 5, 22-1 . . . 5) is angled downwardly and inwardly from each door for pivotal attachment to the underside of the base section (30). The combined curvature of the legs (12-1 . . . 5, 22-1 . . . 5) and the doors (10, 20) allows opening without a need for frontal clearance. In addition, the legs (12-1 . . . 5, 22-1 . . . 5) are pivoted to the base section (30) in such a way that they may be locked in the full-open position, thereby freeing both hands for servicing.
Abstract:
An enclosure (10) for terminal blocks for connection of telephone service cables (22,272,276,322,326) to others thereof or to a distribution cable (16) providing for mounting therewithin of different types of terminal blocks (200,250,300). Several ribs (86) extend across the bottom wall and upwardly to coplanar top edges (88) to support the various types of blocks as several projections (96,124) extend upwardly between at least two of the ribs to top edges (98,126) coplanar with the rib top edges (88) and include apertures (100,132) thereinto for receipt of fasteners for mounting of the terminal blocks (200,250). A ground plate (350) is also mountable in the enclosure atop rib top edges (88) in turn permitting mounting to the top surface thereof of certain terminal blocks (300) having ground contacts (310) requiring grounding. A lid (12) is pivotable to a stable open position.
Abstract:
A protector module (50) includes a housing (52) having cavities (58) into which are inserted surge protector elements (150). Each protector element upon full insertion engages a deflectable contact portion (82) of a first contact member (80) with an active electrode (156) thereof with the first contact member terminated at a second contact section (88) to a line between a central office and the customer, for providing surge protection to that circuit. In one method of connecting a protector module in a circuit, a second contact member (90) is placed within the cavity (58) connected to the customer service line while the first contact member is connected to the associated but separate line to the central office; when a protector (150) is inserted, it urges the deflectable contact portion of the first contact member (80) into engagement with an underlying contact portion (92) of the second contact member (90); when a protector is absent, service to the customer is interrupted until the protector (150) is replaced.
Abstract:
A one-piece insulation displacing terminal having a first portion, a second portion, and a connecting portion connecting the first and second portions. The connecting portion is torsional in order to permit the first portion to rotate relative to the second portion. In one embodiment, the first portion has adjacent first and second walls which are arcuately shaped and which have wire receiving openings therein. The wire receiving openings have associated wire receiving slots. The second portion is mounted in an insulating housing of a connector assembly on a post having a post opening therethrough which has a conical reducer for permitting only wires of predetermined gauge to pass therethrough. After the second portion is secured to a base of the insulating housing, a wall portion of a cap may be slidable mounted between the first and second walls of the first portion. The wall portion has an opening therein to permit a wire to pass between wire receiving openings in the first and second walls. An insulated wire can be inserted through an opening in the insulating housing into the wire receiving openings. The cap can then be turned to cause the first portion to rotate relative to the second portion which in turn causes the insulated wire to become terminated in the wire receiving slots.
