  • Patent number: 4352950
    Abstract: A radiation tight connection device for a cable containing a screening mesh or wire which is fixed by clamping. An insert equipped with an insert cone and a collar formed thereat is inserted substantially axially parallel in a conical bore of a screw cap or retaining nut. Provided at the insert cone is an external or outer conical contact surface which corresponds to or is complementary to an inner contact surface of the conical bore of the retaining nut. During assembly the screening wire or mesh is fixed by clamping between both of the contact surfaces. The invention preferably is used in conjunction with plugs or the like.

  • Patent number: 4345370
    Abstract: A cable is prepared for mounting a connector, by initially deforming a helically wound strip of the cable to prevent it from unwinding. Then, an outer braided conductor and an outer sheath are cut and stripped from the cable end. Next, a sleeve is inserted beneath the braided conductor, a ferrule is positioned around the cable at the sleeve and the ferrule is clamped to the sleeve. The sleeve can have a flange for mounting the connector in clamped relation on the flange.

  • Patent number: 4331374
    Abstract: A cable terminator assembly for a coaxial cable includes a housing having a raided extension affixed thereto for transferring tensile strength from a cable to the housing and braided extension. An inner cylindrical piece is swaged to the housing for holding the braided extension in place. A dielectric clamp with a closure ring, flat locking washer and cap complete the components within the termination. The washer is keyed to the housing and, together with the housing, clamp the stranded cable conductor. The keying prevents turning of the mating components so that the stranded cable conductor will not be damaged. The clamping of the strands makes electrical contact between the strands and the assembly. The dielectric clamp is forced to bite into the dielectric material of the coaxial cable. This provides a firm mechanical hold.

  • Patent number: 4329537
    Abstract: A crimp-type cable shield bonding device for electrically interconnecting the shields of two sheathed and shielded cables each having an outer protective sheath and an underlying shield which enclose a bundle of conductors. The bonding device includes two tubular clamps respectively connectible to adjacent ends of the two cables. Each tubular clamp comprises a generally semicylindrical outer portion adapted to fit over the outer protective sheath at one end of one of the cables and a generally V-shaped inner portion within such outer portion, with its apex extending toward the outer portion. The inner portion of each tubular clamp is insertable between the shield and the conductors at the corresponding end of the corresponding cable with its apex extending toward the shield. The inner portion of each tubular clamp has teeth extending toward the outer portion of such tubular clamp and adapted to penetrate the shield of the corresponding cable.

  • Patent number: 4222056
    Abstract: Apparatus for connecting the female connector end of a coaxial antenna lead to the members of a slot antenna includes a first connecting member having a flat base connected to one antenna member with a pair of arms at the base end farthest from the slot adapted to engage the female end of the coaxial lead and connect the outer conductor to the one antenna member. A forked extension projects from the base end nearest the slot, and the base flares outwardly in width from the arms to the forked extension to dissipate the radial electromagnetic field of the coaxial lead so it does not interfere with the slot. A second conducting member includes a conductor adapted at one end to engage the inner conductor at the female connector end of the coaxial lead and at the other end to engage the other antenna member. An insulator engages the forked extension to interlock the first and second connecting members.

  • Patent number: 4176244
    Abstract: This invention is an improved connection for splicing or terminating coaxial cables. The connection of this invention maintains substantially the same ratio of outer conductor inside diameter to inner conductor outside diameter as in the rest of the cable, and thus avoids impairment of signals transmitted by the coaxial cable. The splices prevent moisture from entering the cable when used underground; and the splices are strong enough to permit the cable to be plowed in with no fear of splice hang-up in the plow guides.

  • Patent number: 4139724
    Abstract: A coaxial, hermetically sealed end structure is described for electrical instrumentation cables. A generally tubular ceramic body is hermetically sealed within a tubular sheath which is in turn sealed to the cable sheath. One end of the elongated tubular ceramic insulator is sealed to a metal end cap. The other end of the elongated tubular insulator has an end surface which is shaped concave relative to a central conductor which extends out of this end surface. When the end seal is hermetically sealed to an instrumentation cable device and the central conductor is maintained at a high positive potential relative to the tubular metal sheath, the electric field between the central conductor and the outer sheath tends to collect electrons from the concave end surface of the insulator. This minimizes breakdown pulse noise generation when instrumentation potentials are applied to the central conductor.

  • Patent number: 4124772
    Abstract: A main transmission line with inner and outer metallic layers on a dielectric tube is joined to a coaxial branch line via a pin and a sleeve forming extensions of the inner and outer conductors of that branch line, the pin penetrating two diametrically opposite bores of the dielectric tube while the sleeve is in contact with the outer metallic layer. Two lugs on the sleeve are soldered to that outer layer whereas a connection between the inner layer and the pin is established via a conductive coating of the wall of the remote bore which terminates in a metallic patch surrounding the outer end of that bore, the patch being insulated from the outer layer of the tube and being soldered to the projecting tip of the pin.

  • Patent number: 4046451
    Abstract: A connector assembly for a coaxial cable having an annularly corrugated outer conductor has a first unitary clamping member which fits over the end of the coaxial cable and forms an inwardly extending bead at one end thereof for meshing with the last valley in the corrugated outer conductor, thereby locking the clamping member to the cable in the axial direction. One side of the bead also forms a first conically beveled clamping surface for engaging the outer surface of the last crest in the corrugated outer conductor. When the clamping member is advanced over the cable during installation of the connector assembly, the bead cams a plurality of resilient segments in the beaded end of the clamping member outwardly to clear the crest of the corrugated outer conductor.
