Abstract:
An enclosure for terminal blocks for interconnecting conductors of multiconductor cables includes provision for two or more terminal block modules. Each terminal block module includes two terminal blocks defined by a tubular housing section extending from a common base section of a dielectric housing and has an annular cavity extending to an open end, and a tubular one-piece terminal is secured therewithin around a center post of the housing section and is rotatable therewithin by a generally tubular actuator also within said annular cavity and adapted to be rotated during splicing of wires. Each terminal block includes a pair of wire-receiving apertures into which wire ends are inserted to extend through insulation piercing slots of said terminal, and upon actuating rotation said slots pierce the insulation and engage the conductor of each wire thus interconnecting them.
Abstract:
A multiple piece terminal includes a first section which is stationary relative to the housing of the connector and rotatable sections which are rotatable relative to the first section. Each of the sections is comprised of a single thickness of metallic material wrapped into a substantially cylinderical configuration, where the rotatable sections are of a larger outer diameter than the first section such that the rotatable sections can engagingly overlie the first section. The first section is mounted to an insulative housing with a post section upstanding through the center of the first section. The post has at least one through opening which includes at least partially along its length, a frusto-conical section for wire section through the opening. The rotatable sections of the terminal has two wire receiving openings, each in communication with a wire-receiving slot around the circumference of the cylinder, with the two wire receiving openings being on opposed sides of the through opening on the post. Caps fit over the rotatable sections of the terminal, each cap has a shoulder which is engagable with a free end of a respective rotatable section of the terminal for rotation of the rotatable section of the terminal relative to the first section of the terminal. When wires are placed in through the caps and the caps are turned, the rotatable sections of the terminal are rotated and the wires are terminated in the wire-receiving slots.
Abstract:
An electrical safety receptacle (10) including a dielectric housing (12), first electrical contacts (14) in the housing for electrical connection to one side of an electrical power line, second electrical contacts (16) in the housing for electrical connection to the other side of the electrical power line, and power-interruption members (48) provided as part of the second electrical contacts to interrupt the electrical power when an operating and/or environmental temperature exceeds the thermal rating thereof.
Abstract:
A subscriber module (40) for a network interface device (10) having a jack (100) defining a plug-receiving cavity (102) thereinto, and having a plug (50) insertable into the jack. The plug includes a plurality of interconnecting contacts (56) disposed at a mating end (58) thereof, and the jack includes first and second contacts (106,112) secured within the plug-receiving cavity in spaced-apart disconnected pairs. Insertion of plug (50) into jack (100) moves interconnecting contacts (56) between associated ones of first and second contacts (106,112) to electrically interconnect them, completing otherwise unconnected circuits between the distribution cable and the subscriber premise wiring. Preferably plug (50) includes a sealing member (74) therearound to seal the mating interface when plug (50) is inserted into jack (100). Conductors (36) of the premise wiring are terminatable by insulation displacement techniques to terminals (164) using a stuffer cap (152), with terminals (164) connected to second contacts (112) by traces of circuit board (170) mounted within module (40), while first contacts (106) are electrically connected by other traces of board (170) to conductors (38) connected to the distribution cable.
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. The enclosure (200) may be used to splice aerially suspended cable (202) by grooves (208) between the hinge (216) and the latches (218) proximate the hinge (216), receiving thereinto a length of suspension wire (206) spliced to suspension wire (204) thus securing enclosure (200) to cable (202).
Abstract:
A terminal block assembly (10) including at least two terminals (20) and associated actuators (24) in housing sections (14) for termination to ends of conductors (28,30) inserted into aligned apertures therethrough upon actuation of the terminals. Bridging element (50) includes contact sections (54) held in cavities (22) of housing sections (14) to be assuredly compressed against terminals (20) thus electrically interconnecting terminals (20) and commoning all wires (28,30) terminated by terminals (20). A cover member (90) may be secured beneath the terminal block assembly for insulative protection.
Abstract:
An electrical connector 10 having a housing 12 containing a terminal 30 of the type adapted for insertion of an end of a wire 40,42 through a wire-receiving aperture 14,16 thereof for termination, includes a substrate 50 adhered to the outer housing surface and traversing the wire-receiving aperture with a corresponding hole 52,54 aligned therewith to permit wire insertion. The substrate may be tough elastomeric tape, and the hole is smaller than the wire diameter to tightly grip the wire insulation after wire insertion to assuredly retain sealant material within the connector upon wire withdrawal.
Abstract:
A single modular assembly (10) has two terminals (18) in housing cavities (28) each with a pair of slots (38) for termination by rotary actuation to respective conductors of two cables, for crossconnecting or splicing the tip and ring lines of a customer's service line with those of a cable extending to the main distribution line. Each terminal (18) is in electrical engagement with a circuit wire (40) extending to a separate portion (20) of the module for electrical connection to an active electrode of a protector element (24). The two protector elements (24) each include a ground electrode (76) grounded to a common ground strap (54) which includes a contact section (60,64) exposed along the bottom of the module to be assuredly engaged with a ground strap (122) along the floor (112) of the enclosure (110) upon mounting of the module (10) therein, for grounding to a ground stud for external system grounding.
