Abstract: 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.

Abstract: 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.

Abstract: A connector for connecting an end of a first elongate electrical heating cable to an end of a first elongate electrical component such as another heating cable or a power cable. The connector includes first and second shell members which can be in a mated or demated configuration and which, when mated, form a shell having a first inlet port for the first heating cable and a second inlet port for the first electrical component. In addition, the connector includes an element for connecting electrodes of the first heating cable to elongate members of the first electrical component and a sealing assembly for holding the first heating cable in position in the first inlet port. The sealing assembly includes a hollow cylindrical ring from which gripping elements in the form of fingers extend perpendicular to the plane of the ring, a nut for making connection to the first inlet port, and a grommet which is held by the fingers and which grips the first heating cable.

Abstract: 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.
