  • Patent number: 5954534
    Abstract: A lamp socket assembly having insulation piercing and displacing contacts which make electrical and mechanical joints with the two conductors of an electrical lamp cord. The contacts have two pointed ends to pierce the insulation and a slot between to sever and displace the insulation from the contact which is arranged transverse to the path of the cord in the socket. An actuating lever, pivotally mounted to the socket body, is held in different ratchet controlled position ranges to hold the lever and socket in assembly and accept the cord end and then force the cord in to the insulation piercing and displacing contacts. A strain relief member is made to engage the cord when the lever is fully operated.

  • Patent number: 5928032
    Abstract: An electrical conductor of the type known as a power adapter for connecting a power supply to a coaxial cable comprises a central metal conductor having a known type coaxial cable type coupler at one end and a flat plate terminal at the other end. The conductor is surrounded by a tubular insulator surrounded, in turn, by a tubular metal sleeve. At the one end of the adapter, the metal sleeve terminates in a threaded metal tube which surrounds, in electrically spaced apart relation, an axially extending portion of the central metal conductor either in the form of a solid plug extending beyond the metal tube or a hollow receptacle terminating inwardly of the end of the metal tube. Intermediate the two ends of the central conductor, the sleeve contains a plurality of axially extending flat surfaces spaced circumferentially around the sleeve. Two power supply wires are connected, respectively, to one of the sleeve flat surfaces and to the central conductor plate terminal.

  • 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.

  • Patent number: 5895291
    Abstract: A shielded cable connector comprises a terminal section and a cable section. The cable section comprises support shells mountable over shielding of the cable, and clamping half-shells that have ends engageable in grooves of the support members. The clamping half-shells are pivotable together to clamp a shielding braid that is reversely folded over a cylindrical portion of the support members. A retention ring is passed over the clamping half-shells to securely lock them to the terminal section. Assembly of the shield clamping portions is thus enabled after the terminals are mounted in the connector for a more cost-effective assembly procedure.

  • Patent number: 5890932
    Abstract: A resilient contact piece portion is provided within a connection portion of a female metal terminal, and is folded back at a position spaced forwardly from a front end of the connection portion, thus forming a folded portion of a generally inverted V-shaped cross-sectional shape. Relief recesses for respectively receiving the projected folded portions are formed in a front plate of cavities in a female housing. Thus, a contact portion is shifted forwardly within the connection portion while the cross-sectional shape remains unchanged as before. The contact portion of the resilient contact piece portion is shifted forwardly, and therefore even if the length of projecting of a tab portion is short, a positive electrical connection between the tab portion and the resilient contact piece portion is achieved.

  • Patent number: 5879199
    Abstract: Disclosed is a modular jack assembly comprising an outer insulative housing having top and bottom walls and opposed lateral walls which define an interior section of the housing having front and rear open ends, and an insulated insert having a first section superimposed over the rear open end of the insulated housing and a second section extending generally perpendicular from the first section into the interior section of the housing. There are engagement points on both the top wall and the opposed lateral walls of the outer insulated housing. Latches may be positioned on the insulated insert on either their first section or their second section depending on the specific configuration of the insulated insert. If latches are positioned on the first section, the opposed lateral walls will be engaged. If latches are positioned on the top section, the top wall will be engaged. A common housing may, therefore, be used for a number of different types of insulated inserts.

  • Patent number: 5876252
    Abstract: A connector assembly comprises a mounting portion for mounting the connector to a complementary portion which could be either another connector or a member fixed to a structure such as an automobile's bodywork. The mounting portions comprise interengaging T-shaped walls and T-shaped profiles that are longitudinally slidably interengaged. The mounting portion walls comprise interleaving recesses and extensions and that enable the mounting portions to be interengaged by placing the mounting portions one against each other and then sliding them in opposing directions by only a short travel. The latter enables longitudinally slidable T-profiles to be used but nevertheless over short travel which is advantageous for certain applications to reduce cable length surplus.
