Abstract:
A cord assembly including an insulated electric cord containing a plurality of twisted pairs of insulated solid wire conductors and terminated by a plug having an inner part and an outer part. Terminal end portions of the conductors wrapped about an inner part and trapped between the inner and outer parts extend across an opening in the plug for direct releasable plugging connection with an inline array of insulation displacement contacts (IDCs) carried by a mating connector block mounted on a cross-connect panel. An assembly jig is used to position the conductor terminal end portions and supports the inner part while the terminal end portions are wrapped about the inner part.
Abstract:
The invention provides a telephone network connector (10, FIG. 8) with a rear portion (47) that holds a cartridge (56) which enables connections directly to ground and through a circuit component to ground. The cartridge lies within an electrically grounded metal shell (32), that, in turn, lies within a molded dielectric container (48). The cartridge has a grounded contact element (74, FIG. 2) which has threaded part (78) extending through a threaded hole (80) in the grounded shell. The cartridge also has a nongrounded contact element (76) which projects through a bushing part (92) of the dielectric container, which isolates the nongrounded contact from the walls of a hole (91) in the metal shell. The molded dielectric container forms a front connect tube (51, FIG. 8) and a pair of side tubes (52, 53).
Abstract:
A rotatable connector installed in a telephone transmitter and used for connecting a coiled conductor and the transmitter to effectively prevent the coiled conductor from twisting. The connector includes a housing, four conductors for connecting to a microphone and a receiver in the transmitter, four annular guide pieces which can be mounted on a rotation seat and held in the housing and composed of four semicircular piercing guide pieces and four semi-circular guide pieces, a jack for the coiled conductor held in the housing and having several electrically conducting spring strips thereon. The jack can be freely rotated relative to the housing while keeping the spring strips in electric contact with the corresponding annular guide pieces.
Abstract:
An environmentally protected electrical socket and plug assembly (10) retains environmental security throughout repeated connections and disconnections. The socket and plug assembly includes a socket 100 containing an electrical conductor 85 and adapted to insertably receive a plug 90, an environmental sealant at least partially filling the socket so that the sealant is at least partially displaced from the socket when the plug is inserted into the socket, and an elastomeric containment means 40 having an inset dimple for being outwardly deflected to contain displaced sealant when the plug is inserted into the socket and to urge the sealant back into the socket when the plug is removed.
Abstract:
The present invention relates to an integrated outlet that allows supply of AC power to an outlet receptacle when certain conditions are satisfied. The integrated outlet contains separate modules establish electrical connection with electrical conductors that transmit AC and DC power, telecommunications, control communications, and signals transmitted along a coaxial wire. In a preferred embodiment, these electrical conductors are all disposed on a single ribbon cable. Each module within the integrated outlet can attach to only certain conductors to increase safety in the resulting system.
Abstract:
A patch panel is disclosed which is easily expandable as required by a customer and which substantially simplifies conventional field servicing practices. The invention provides a patch panel comprising an assembly of at least one connector and printed circuit board with the connector being mounted upon the printed circuit board; a mount for removably supporting the assembly of at least one connector and printed circuit board in a desired location relative to the mount and a panel for detachably holding the mount in a predetermined position to the panel such that the panel prevents removal of the assembly of at least one connector and printed circuit board from the mount.
Abstract:
A special purpose modular connector comprising a generally rectangular housing having a central body portion and two extending side arm portions. A plurality of electrical contacts are disposed within the body and arm portions. Slots at a front end of each portion of the housing expose a terminal end of each electrical contact. Openings in the rear portions of the housing allow connection of cables or other types of component wiring to the contacts. A locking tab is formed at the underside of the housing and functions to align and securely connect the special purpose modular connector with a correspondingly modified receptacle.
Abstract:
An anti-overstress system is provided in an electrical connector which includes a dielectric housing having a contact-receiving cavity with a slot communicating the cavity with a mating surface on the outside of the housing. A contact is received in the cavity and includes a cantilevered spring contact arm disposed in the slot. The arm has a contacting portion projecting beyond the mating surface of the housing for engagement with a complementary contact of the mating connector. The spring contact arm flexes in the slot upon engagement of the contacting portion by the complementary contact. The anti-overstress system is provided between the contact and the housing and includes a pair of wings projecting from opposite sides of the spring contact arm engageable with a pair of ledges formed in opposite sides of the slot after a given amount of flexing of the spring contact arm.
Abstract:
A communications card capable of being mounted in electrical communications with a computer has formed therethrough an aperture so sized and shaped as to be capable of receiving a physical/electrical media connector. The media connector has a biased retention clip, a contact pin block, and contact pins. The retention clip has several standardized characteristics including a broad fixed end protruding from an outer surface of the contact pin block. The broad fixed end tapers abruptly at a transition notch down to a narrow free end, capable of being manipulated by a user to remove the physical/electrical media connector from the aperture in the communications card. In use, a media connector is inserted directly into the aperture in the communications card, the aperture being in contact with a plurality of contact wires fixed within the communications card. The communications card is divided into a retractable access portion of the communications card which can be directly accessed by manipulating an actuating mechanism releasing a retention means thereby allowing a spring to push the retractable access portion of the card outside of the computer housing. The retractable access portion of the communications card may be reinserted back into the computer housing to be carried internally when not in use.
Abstract:
An electrical connector for connecting together cables containing at least two twisted wire pairs which transmit and receive different electrical signals, The connector has an electrically conductive shield between pairs of connector elements which are respectively connected to the different twisted wire pairs. The connector also has an insulative block with printed circuit segments and switch contacts which together form shunts to connect the twisted pairs together when the connector is disconnected.
