  • Patent number: 4784609
    Abstract: A jack module with a lamp assembly that is interconnected at the top front of a printed circuit board and has a bottom guide channel for slidably receiving a tri-jack. The printed circuit board has top and bottom forwardly extending necks which define a notch therebetween. The lamp assembly has a lamp housing with a hollow trunk and tow legs that provide upwardly and downwardly facing channels that slide onto the bottom and top edges of the top neck. The housing, which has a longitudinal bore holding a lamp, encases conductive strips which engage the lamp. The housing is locked to the neck by a retainer that has a boss that snaps into an aperture in the housing. A guide housing is similarly connected to the bottom neck. The lamp housing and bottom guide housing have facing guide channels which respectively receive top and bottom guide rails of the tri-jack in slidable engagement back to a printed circuit board connector in the notch.

  • Patent number: 4781622
    Abstract: A triaxial contact assembly for use with a ground plane electrical connector includes an outer conductor which is grounded to the ground plane of the connector. The intermediate and inner contacts of the triaxial contact assembly have printed circuit board tails on their ends. The arrangement is such that bonding of the insulators to the contacts is eliminated via a cap which holds all internal contact assembly components in place. The cap, in turn, is held in place by crimping the outer contact.

  • Patent number: 4781619
    Abstract: In a connector in which a plurality of wire connector terminals are inserted into a connector housing, a first marking is formed at the same position of the wire. Therefore, when a connector terminal is not prefectly inserted into the connector housing, the first marking on the imperfectly inserted terminal is misaligned from the other markings arranged on a parallel line. Further, a second marking is formed on the wire in such a way that the marking distance from the connector terminal increases in incremental steps from one extreme end wire to the other extreme end wire. Therefore, when two connector terminals are not correctly inserted into the connector housing, the second markings on the incorrectly inserted terminals are misaligned from the other markings arranged on an inclined line, thus allowing simple visual inspection of imperfect and incorrect insertions of connector terminals into the connector housing.

  • Patent number: 4781611
    Abstract: A zero insertion force electrical contact assembly is provided. The assembly comprises a bifurcate contact and a trifurcate contact. The bifurcate contact includes a pair of parallel contact beams cantilevered from a base. The contact beams include cam surfaces adjacent outwardly disposed portions remote from the base. The contact beams further include contact surfaces facing one another. The trifurcate contact includes a base, a central contact post extending from the base and a pair of cam arms extending from the base and on opposite sides of the contact post. Inwardly facing portions of the cam arms include converging cam surfaces. The cam arms and the contact posts are dimensioned to enable the contact arms to be disposed between the cam arms and around the contact post with little or no contact forces. Upon sufficient insertion, however, the respective camming surfaces will cause the cantilevered contact beams to be urged toward one another and into electrical contact with the contact post.

  • Patent number: 4780087
    Abstract: An edge connector for connecting a conductor run on an edge region of a first circuit board to a conductor run of a second circuit board comprises a plate of dielectric material. The plate has a generally U-shaped portion, with the two limbs of the U defining a slot therebetween. The plate of dielectric material may be attached to the second circuit board in a position such that an edge region of the first circuit board may be received in the slot. A signal conductor is adhered to one main face of the plate of dielectric material and has two end portions. One end portion of the signal conductor projects from one of the limbs of the U into the slot for engaging a conductor run on the edge region of the first board, and the other end portion projects from the plate at a location remote from the slot for contacting a conductor run of the second board.

  • Patent number: 4778401
    Abstract: A card cage includes upper and lower support members which define a slot for receiving a printed circuit board. An engagement mechanism includes one or more handles pivotally mounted on the front of the card cage. Each handle, in turn, is pivotally attached to a rod which extends to the rear of the card cage and terminates in an extraction member which receives the rear corner of a cirucit board. When the circuit board is mounted in the card cage, the handle is pivoted to contact the forward edge of the board and urge it into position in the cage, thereby urging contacts along the rear edge of the board into engagement with a connector at the rear of the card cage. When the board is to be removed from the card cage, the handle is pivoted in the opposite direction, enabling the extraction member at the rear to pull the board forwardly out of engagement with the connector and permitting the board to then be removed from the card cage.
