  • Patent number: 4547028
    Abstract: The present invention is an electrical clip-like connector that has a low profile and is capable of connecting the conductors of an electrical cable, for example, with the leads of an integrated circuit package or the like. Due to the low profile configuration of the invention, it may be used in situ in confined environments, and it also may be used for coupling relatively high speed signals without or with minimum antenna effect. Other features of the invention include a locating mechanism that facilitates applying the clip connector to an integrated circuit assuring proper alignment of the contacts and leads and a preferred contact/support arrangement to help assure good electrical connection with the integrated circuit leads and tolerance for size and location errors while avoiding overstress damage to the contacts.

  • Patent number: 4420215
    Abstract: An electrical contact includes a contacting means for electrically connecting with a member inserted to engagement therewith and a support means for supporting the contacting means in position for such engagement. The support means includes at least one cantilever arm having an effective length that varies during deformation thereof in response to a member inserted to engagement with the contacting means. Moreover, the contact is positioned in a cell-like containment portion of a relatively fixed housing having a wall against which the cantilever-like portion may be supported at various locations along the length thereof. The combination may be employed as an electrical breadboard to facilitate making electrical connections.

  • Patent number: 4105278
    Abstract: A molded cable termination assembly for terminating a woven cable, which has a fabric-like woven insulation about the conductors thereof, includes in one embodiment a pair of clamping pads tightly clamped against the woven cable during injection molding of a housing base directly to the cable to prevent wicking of the molding material along the cable exteriorly of the mold. In another embodiment, a lip seal arrangement securely grips the woven cable in response to the pressure exerted during the injection molding process to prevent such undesirable wicking. The latter embodiment also is effective to provide strain relief holding of the cable in the molded housing base and, therefore, enables molding a cable termination direction to non-bondable, non-wettable or like cables.

  • Patent number: 4052117
    Abstract: A socket for dual in line package integrated circuits has a high retention force for a correspondingly low insertion force. Each of a plurality of contacts in a dielectric housing bends relatively easily as a lead of such package is inserted and as such insertion is completed the contact assumes a residual position for good electrical and mechanical connection to the lead. Friction between the lead and contact effects movement of the latter to change the geometry thereof as the former is withdrawn, whereby the contact binding force against lead increases to increase the force required for completion of such withdrawal.

    Abstract: A multiple switch device is connectable on-line between a multiple conductor electrical cable termination assembly or the like and a receptacle or the like to which the assembly would otherwise be connected. The multiple switch device includes a plurality of slide switches that are selectively actuable to slide directly on contacts integrally molded in a common body part of the device to open or to close respective circuits. A plastic bridge molded in the common body part between respective pairs of contacts over which a common slide switch glides provides a generally continuous planar surface to facilitate such motion without unnecessary wear to the contacts or the slide switch.

  • Patent number: 4011508
    Abstract: A probe for testing logic signals or the like occurring in electric circuits and for indicating whether such signals are at low, intermediate or high level or that an open circuit exists in the tested circuit includes first and second parallel connected display portions, the former having a first liquid crystal indicator in series with a battery the latter including a second liquid crystal. The first liquid crystal is normally energized when the difference between the battery voltage and the received signal being tested exceeds the threshold level thereof, and the second liquid crystal is normally energized when the voltage of the received signal being tested exceeds the threshold level thereof, such energization indicating whether the tested signal is at high or low level. De-energization of both liquid crystals indicates that the tested signal is at an intermediate level, also known as the deadband region between low and high level signals, or that an open circuit exists in the tested circuit.

  • Patent number: 4008300
    Abstract: A method for making a multi-conductor element includes forming a plurality of holes in an elastomeric base using a laser or mechanical technique to perforate the base and filling each of the holes with a slurry of conductive material in an uncured liquid vehicle. The filling step may be accomplished either by the force of a roller press while the slurry is applied or by stretching the base to expand the holes after which the slurry is applied to the latter followed by release of the base after the vehicle has cured, and in either case the ends of the conductive portions in the holes will bulge slightly above the surfaces of the base. An article manufactured using the method has a capacity or conductive density of at least approximately 11,500 conductive portions per square inch of base.

  • Patent number: 3999126
    Abstract: A test clip suitable for connection to a plurality of terminals at which appear respective logic signals representing those occurring in logic circuits provides an indication of the logic level of such signals. The circuit for effecting such indication is entirely self-contained requiring no external power source or grounding connection and includes a plurality of respective input lines connectable to such terminals with a respective indicator shunted by a reverse poled diode connected to each input line and one common connection for all the diodes and indicators. Thus, for example, a logic 1 signal occurring on one of the input lines will effect a current flow through a respective indicator to change the state thereof with a return current flow path being provided from the common connection through at least one of the shunting diodes connected to another input line then at logic 0 relatively ground potential.
