  • Patent number: 5993237
    Abstract: A modular telephone plug having an elongated dielectric housing and a clip member attached that is adapted to fit into a standard RJ-type jack. More specifically, one end of the modular plug defines an electrical connector section to which wires from a telephone cord can be attached. For this purpose, the housing includes an internal channel through which the telephone cord can extend. The clip member is secured in a cantilevered manner at an end of the housing remote from the electrical connector section. The housing is also formed with a recess into which extends a free end of the clip member. The modular plug has an associated length of 1.1 to 1.5 inches (approximately 2.8 to 3.8 cm). With this construction, the modular telephone plug can be easily grasped and manipulated.

  • Patent number: 5961354
    Abstract: Electrical connectors for electrically and physically connecting cable conductors to mating connectors frequently require precise and demanding assembly in order to produce a required level of crosstalk. In many instances, this level must be a set amount, rather than the lowest level possible, in order to match a canceling crosstalk being produced in the mating connector. The present invention is a crossover lead frame connector which reduces the demands upon the assembler in assembling the connector and cable, and yet still provides the precise level of crosstalk required in the connector. These advantages are realized by the use of a crossover lead frame structure which controls the physical length and routing of the signals between the cable conductors and connector pins. This allows the manufacturer to match the connector to the layout of the cable conductors and fix the level of crosstalk that will be produced at the time the connector is manufactured.

  • Patent number: 5921818
    Abstract: A high frequency electrical connector includes a number of input terminals and output terminals that are interconnected by three metallic lead frames mounted on a dielectric spring block. The lead frames comprise flat elongated conductors, each terminating in a spring contact at one end and an insulation displacement connector at the other end. The lead frames are mounted on top of each other and their conductors are generally parallel and close to each other. Selected conductors of the lead frames crossover each other when they are mounted on the spring block but are prevented from making contact with each other at the crossover point. One pair of adjacent conductors are spaced a first distance from each other up to the crossover point, and a second, greater distance from each other beyond the crossover point for a portion of their lengths. The conductors of the one pair cross each other at a second crossover point.

    Abstract: A modular plug connector and cable assembly comprises a modular plug with a wire holder, and a twisted pair cable. The twisted pairs are braided in order to cross over conductors of the twisted pairs, and furthermore to separate the pairs of conductors and from and in order to reduce inductive and capacitive coupling therebetween. The wire holder helps to keep the pairs twisted and the straightened end portions of the conductors as short as possible. The cable assembly as described provides low cross talk and enables consistent termination with little deviation in the signal transmission speeds.

  • Patent number: 4869682
    Abstract: A bridging link for connecting terminals in an electrical terminal device in which a body of the link provides a plug body for insertion into a telephone jack. Electrically conductive lines extend from terminal positions in the plug body to terminal positions spaced from the plug body. The conductive lines may be electrically conductive strips extending through passages which are preferably open at one side for lateral insertion of the strips. A latch arrangement is advantageously used to connect the link to the telephone jack and the latch arrangement is spaced from the plug body.

  • Patent number: 4790769
    Abstract: A telephone modular jack includes a base for receiving thereon a contact block carrying an array of spring contacts, the corresponding number of terminal units, and a cover, all mounted downwardly upon the base to be capable of being assembled by an automated technique. Each of the terminal units has a lug which is press-fitted to each one of lead tabs extended from the spring contacts when the contact block is mounted on the base. Each spring contact has a first end portion, a middle portion, and a second end portion, the portions being bent with respect to the others. The contact block includes a upright support and a horizontal support in parallel with the base. The middle portion of each spring contact is molded in the upright support in such a manner as to project the first end portion from the top of the upright support diagonally downward to the base, while the second end portion extends through the horizontal support and projects therefrom to define the lead tab at its end.

  • Patent number: 4786259
    Abstract: A low profile modular telephone receptacle (15) is shown. A unitary housing (16) having a pair of transverse support members (35, 36) is provided. A top plate (17) having the necessary plurality of conductors (20) embedded therein is also provided. During assembly, the ends (22, 25) of the conductor are bent to predetermined angles (62, 65) and the top plate is joined to the bottom plate by ultrasonic welding. The resultant receptacle is one in which a minimum height dimension (h) above the necessary height dimension of the opening (18) to accept a standard modular plug is provided. In the preferred method of construction, the top plates (17) are injection molded onto continuous strands of filaments to form the conductors (20). A plurality of slots (55, 56) are provided at one end of the top plate to guide the conductors corresponding openings (46) in the bottom plate when the ends of the conductors forming a terminal set for connecting the receptacle to a utilization circuit are fabricated.

  • Patent number: 4717217
    Abstract: An electrical connector or modular jack for directly coupling a printed circuit board and a standard, miniature, telephone-style modular plug. The jack housing includes an opening in the front portion thereof for receiving the modular plug that features a plurality of planar, insulation-piercing contact terminals. The jack includes conductors having spring contact portions that extend angularly forwardly from the rear part of the opening to be engaged with the similarly spaced contact terminals of the modular plug. The other ends of the jack's conductors extend normally from an outer wall of the housing in an alternating, staggered fashion to fit within correspondingly spaced apertures in the printed circuit board. An alternate embodiment provides a low profile modular jack particularly adapted for use with closely-spaced printed circuit boards. The low profile embodiment features a side-mounted latching assembly.
