A method of forming a tap into an intermediate point on a continuous coaxial cable, and a coaxial cable tap housing suitable for forming such a tap. The tap housing includes a recess and an alignment element having a predetermined spatial relationship with the recess. The recess has an entry, an exit and a passage connecting the entry and exit. When the tap housing is fixed to a cable, the exit of the recess is closer to the outer conductor of the cable than the entry of the recess is to the outer conductor. The alignment element is used to position a cutting tool which is inserted through the entry of the recess to form an opening in the outer conductor and a cavity in the dielectric under the opening. A tap insert, which includes a coupler assembly, is mounted to the housing, and the coupler assembly is inserted through the entry of the recess and through the opening into the cavity formed in the cable. In specific embodiments, the recess and opening are elongated.

Coaxial cable tap with slitted housing and non-piercing tap insert

An inexpensive coaxial cable connector, and an inexpensive contact which is suitable for use in an such an inexpensive coaxial cable connector, the connector and the contact being capable of passing electrical signals from low frequency power up to and including telecommunications signals in the range of 1 GHz or more. The connector comprises an elongate, hollow, conductive, cylindrical barrel having an inner radius, R.sub.BARREL, and a first longitudinal axis; and an elongate, conductive contact. The contact has a first end and a second end which define a length therebetween, a second longitudinal axis, and comprises a cylindrical section. The cylindrical section has an outer radius, R.sub.CONTACT, which is less than R.sub.BARREL. The cylindrical section comprises a first external end which is coincident with one of the first end and the second end of the contact, a hollow interior, a first longitudinal slot, the slot located near the external end of the cylindrical section, and has a proximal end and a distal end. The contact also comprises a first spring-tab which is located within the first longitudinal slot and formed from a cut-out which forms the first longitudinal slot. The spring-tab has a fixed end and a free end, the fixed end joined at the proximal end of the slot. The first spring-tab extends generally from the proximal end of the slot toward the distal end of the slot and into the hollow interior of the cylindrical section. The connector comprises means for supporting the contact in the barrel so that the cylindrical section of the contact is contained within and spaced apart from the barrel and the second longitudinal axis is substantially coincident with the first longitudinal axis. The supporting means comprises a dielectric material.

Coaxial cable connector

A sealed F-connector, with a threaded section and a recessed section adjacent the threaded section, has a ring-shaped elastomeric sealing member formed within the recessed section and affixed to the surface of the recessed section. When a connector shell from a mating connector is screwed on, the sealing member deforms as the connector shell screws on over the sealing member, thereby lining at least a portion of the internal thread of the connector shell and at least a portion of the recessed section of the F-connector. The deformed sealing member thereby establishes a barrier to the penetration of moisture between the F-connector and the mating connector.

Sealed coaxial cable connector

The invention provides for a modularized terminal block (100) and an improved method of manufacturing the modular block. The block permits the connection of a plurality of drop wires (550) or other devices (600, 700, 800) in a reversible manner through the use of a standardized plug in module (16) configuration. The module can be optimized for a given drop wire range which then uniformly connects to the base block (10) through a standardized demateable contact (15). The base block (10) electrical contacts (15) are encased in a sealant material (13) such as gel. The mateable plug-in module connectors enclose an electrical contact (24) also surrounded by such sealant (13). Upon mating of the contacts (15, 24), the sealant material (13) is maintained under compression.

An environmentally protected electrical socket and plug assembly (10) retains environmental security throughout repeated connections and disconnections. The socket and plug assembly includes a socket 100 containing an electrical conductor 85 and adapted to insertably receive a plug 90, an environmental sealant 140 at least partially filling the socket so that the sealant is at least partially displaced from the socket when the plug is inserted into the socket, and an elastomeric containment means 40 having an inset dimple 50 for being outwardly deflected to contain displaced sealant when the plug is inserted into the socket and to urge the sealant back into the socket when the plug is removed.

A test system directed to apparatus for transmitting and receiving multiple telephone transmission signals over a single twisted pair. The system converts an analog signal from a local switching station to an 80 ksymbols/sec signal for transmission over a twisted pair by a line card. A remote terminal converts the 80 ksymbols/sec signal back into a conventional analog signal for use in conventional telephone, facsimile or other related equipment. The test equipment separately tests the entire system, the line card portion of the system, the remote terminal portion of the system, and the twisted pair.

The socket and plug assembly includes a socket containing an electrical conductor and adapted to insertably receive a plug, an environmental sealant at least partially filling the socket so that the sealant is at least partially displaced from the socket when the plug is inserted into the socket, and an elastomeric containment means for containing displaced sealant when the plug is inserted into the socket and for urging the sealant back into the socket when the plug is removed.

Maintenance test unit

A modular, re-enterable telecommunications terminal (50), for making and breaking connections with insulated wire conductors, includes one or more base frames (52) supporting wire termination modules (55, 56) thereon, and a multi-pin socket (60) thereon is connected to another base froze (52) by one or more bridging modules (100). The termination modules (55, 56) are manually operable for terminating wires in insulation displacing connectors (70, 85), and are selected and positioned according to the type of terminations desired. Manually pushing and pulling the termination module drivers (65, 80) toward and away from the base frames (52) effects movement of the wires between connected and open positions.

Upon mating of the contacts, the deformation of the containers maintains the sealant material under compression.
