  • Patent number: 5967852
    Abstract: A repairable transmission line connector is provided where the center conductor has a front removable portion, and a rear portion crimped to the center conductor of the transmission cable. An outer sleeve mounted to a first coaxial conductor of the cable includes a removable front portion, and a rear portion crimped to the first coaxial conductor of the cable. An insulator holds the front center conductor wherein the insulator is held by the rear outer sleeve and the front outer sleeve. The front and rear outer sleeves, and the front and rear center conductors form a connector assembly. In a triaxial connector the connector assembly is surrounded by an insulating sleeve disposed within front and rear connector bodies connected to the cable. By disconnecting the front and rear connector bodies (if present) and the front and rear outer sleeves, access to the front center conductor is permitted for replacement of the front center conductor. The front outer sleeve and the insulator can be replaced as desired.

  • Patent number: 5957724
    Abstract: A coaxial connector is provided, of a type that has a front portion (12) where the inner conductor (14) forms a socket for receiving a pin (M) of predetermined diameter (A) (1 mm) and the outer conductor has a front end of predetermined outside diameter (B) (3.7 mm), which enables an increase in characteristic impedance at the front portion of the connector to more closely match the impedance of the middle portion (16) of the connector. A dielectric support (30) that positions the inner conductor within the over one, includes primarily air at the front portion, to increase the characteristic impedance of the front portion without changing its diameter. The insulative support preferably includes a middle portion (72) with ring-shaped locating portions (62, 64) that are closely received in the outer conductor, that closely surround the inner conductor, and that abut shoulders on the inner conductor to fix the position of the inner conductor in radial and axial directions.

  • Patent number: 5474470
    Abstract: First and second arrays of easily mated coaxial connectors are provided, which are of compact construction to enable efficient transmission of very high frequencies and in a compact arrangement. The outer conductor (22, FIG. 5) of a first connector (1) includes a male outer contact part (44) which is received in a female outer contact part (46) of the second connector, which leaves a step (70) where the inside surface of the male contact part is smaller than that of the adjacent female contact part, thereby creating a capacitive discontinuity. The front ends (74, 76) of the dielectric members (24, 34) of the first and second connectors are slightly axially spaced apart to leave a gap (72) between them. The gap produces an inductance that cancels the effect of the capacitance created by the step, to minimize insertion and return losses. The fact that the compensating gap and step are present avoids the need for a butt interface of the outer conductors.

  • Patent number: 4995836
    Abstract: The inventive pin plug connector is advantageously applied to connection of a coaxial cable for electronics, in particular, in audio and video devices. The coaxial cable for such usage comprises a core conductive line, an insulative layer covering the core line, and an outer conductive line defined of networks knitted of thinned copper lines to cover the inner insulative layer. Conventionally, the prior job of taking the network outer line from the cable was needed, but troublesome.

  • Patent number: 4988315
    Abstract: An electrical adapter plug having a body insertable into a mating socket sleeve of a vehicle lighter receptacle. The plug features a pair of ideally located circumferentially-spaced, retractable contacts projecting beyond the periphery of the plug body to establish improved retention and electrical contact between the adapter plug and the receptacle. The two contacts are preferably angularly spaced on the periphery of the plug in the range of about 20.degree. to 150.degree.. Means are located on the periphery of the plug body generally opposite the pair of contacts symmetrically disposed on or about a line which bisects the space angle between the two contacts. Three different embodiments of these means are shown, namely, a groove, a flat surface, and an elongated deformation. All of these embodiments cooperate with the spaced contacts to improve retention.

  • Patent number: 4981445
    Abstract: A unitary three-vane support bead (30) detunes the lowest-frequency transverse cavity modes, forcing resonances toward higher frequencies. Its impedance, compared with that of prior solid beads, is closer to the impedance of an air line. The bead is injection-molded in place, with a radial boss (35) at the radially outer end of each vane (32). Three apertures (14) in the outer conductor (11) capture the bosses, for economical but secure mounting; in fabrication these three apertures serve as injection gates. On its end (29) facing a mating device (65, 65f), the central conductor (21) has an axial bore (26) that holds a cylindrical sheet-metal spring (50). The outward-facing edge (56) of this spring protrudes slightly from the bore and is trimmed to form three distinct contact areas (52), each of relatively small circumferential extent, for kinematically stable engagement with the mating-device central pin (65).

  • Patent number: 4955828
    Abstract: A multiple contact coaxial shell connector combines coaxial, shielded, and multiple contacts in a single connector which need not have angular orientation before mating. The connector is formed by a post, shell, and connector body. The post is formed as an insulating contact-carrying post having multiple electrical contact bands spaced along the length of the post. The post is surrounded by one or more shells, where each shell is formed as an insulating contact-carrying shell coaxially encircling and spaced from the post, each shell having multiple electrical contact rings spaced along the length of the shell. The shell can also contain a encircling shielding layer. The post and shell are mounted at one end to a connector body, leaving the other end open for access to the multiple contacts by a matching socket. The socket has complementary recesses to mate to the connector post and shell, and has leaf spring contacts to contact the multiple contact rings and bands of the post and shell.

  • Patent number: 4907983
    Abstract: An electrical connector having inner and outer conductors along with a sleeve therebetween. The outer conductor has an inwardly directed annular ridge adapted to interlock with an annular recess in the sleeve. In order to maintain contact between the recess of the sleeve and the annular ridge of the outer conductor with changes in temperature, the length of the ridge is related to the diameter of the sleeve at each point along the slope of the beveled wall of the ridge by the equation L=D tan .theta.. In a second version of the invention described herein there is an assymetrical connector in which the opposed beveled end walls of the respective body and sleeve are defined by frusto-conic surfaces of cones each having a common vertex preferably disposed on the connector longitudinal axis.
