  • Patent number: 5273444
    Abstract: A tamper-resistant terminator includes a connector body rotatably encapsulated within a shield. A port in the shield receives a terminal of a cable transmission system therethrough for rotational engagement with a threaded bore within the connector body. Another port in the shield provides access to a socket defined by a smooth continuous cylindrical surface. The socket and the threaded bore extend in opposite directions along a longitudinal axis about which the shield is freely rotatable. A tool includes a tubular shaft having a knurled portion at the free end extends from a first handle section. A disc residing adjacent the end of the tubular shaft is carried by a shaft rotatably journaled with the tubular shaft and drivingly engaged with a second handle section.

  • Patent number: 5141451
    Abstract: A connector for securing the end of a coaxial cable to a selected device in a cable transmission system includes an inner tubular member and a coaxial outer tubular member. The inner tubular member is receivable between the dielectric and the outer conductor of the cable. The outer tubular member, includes a sidewall having a medial thickness which is different than the thickness of either end and a bore for receiving any in a series of cables having differing diameters. In response to a pre-determined inward deformation of the sidewall of the outer tubular member, and outer conductor and the jacket of any cable selected from the series is gripped between the inner and outer tubular members.

  • Patent number: 4738009
    Abstract: A connector and cable preparation fixture to provide a coaxial cable tap while the cable continues to pass signals. The apparatus of the present invention attaches the cable tap without shorting the conductors and without significantly changing the coaxial cable parameters which would affect the data flow therein. The fixture described herein provides a guide for a cutting operation and for the subsequent assembly of the finished connector. The connector includes a cable tap which mounts on the coaxial cable in a perpendicular manner, and a center pin which attaches to the coaxial cable center wire along the axis of the cable tap. The center pin has two prongs spaced apart in opposition to straddle the center conductor. The connector is easily installed with no measurements. The resultingconnection has a long and reliable life without causing an interruption to information or signal flow on the cable at any time.
