  • Patent number: 5286213
    Abstract: An outlet arrangement is disclosed that positively engages the straight terminal blades of most standard plugs. A positive clamping action about the broad sides of the terminal blade holds the plug into the outlet. The user controls the clamping action by moving the plug or some other control element relative to the outlet. The clamping action is unlike the usual friction force provided by most outlets since the clamping force provided by this invention can hold the plug in place whereas the force provided by standard outlets permits easy withdrawal of the plug from the outlet. This invention uses the fact that most plugs have a small depression or hole near the end of its blades. This invention also controls the electrical connection of the terminal contacts with the movement of the locking element to prevent shocks upon initial insertion of the plug into the receptacle.

  • Patent number: 5108301
    Abstract: A locking electrical cord connector includes both male and female contacts. The device includes a housing of electrically non-conductive material including a cylindrical cavity. A pair of opposed plungers are mounted for reciprocation in this cavity. An actuator switch in the form of an elliptical disc is mounted for reciprocation in the housing about a center shaft between the plungers. Each plunger is biased into engagement with the outer cam edge of the disc by means of springs. In use, the male connector of another electrical appliance is connected with the female connector of the device. The female end of a second electrical appliance is connected with the male connector of the device. The actuator switch is then turned so that the plungers are forced outwardly against the biasing of the springs.

  • Patent number: 4919627
    Abstract: The present invention relates to an electrical connector comprising first and second insulating supports (10, 20) respectively provided with first and second terminals (11, 22). The first terminals (11) are moving terminals and the connector includes actuator means (30) for causing said moving terminals to move between a first position (I) in which the moving terminals (11) are held in intimate engagement with the second terminals (22) which are fixed, and a second position (II) in which the moving terminals (11) are held radially away from and fully disengaged from the fixed terminals, with said actuator means (30) responding to the application of axial force to move said moving terminals. This makes it possible to disassemble and to assemble the two supports without having to overcome any friction between the fixed and moving terminals. The invention is applicable to the electrical industry, and in particular to providing equipment for use in manned spacecraft.

  • Patent number: 4846707
    Abstract: The present invention discloses a safety device which has a dual purpose, resisting the insertion of foreign objects or electrical plugs into the outlet without first moving an actuator arm and resisting removal of said plug once properly inserted without first moving the actuator arm. The outlet has at least one receptacle with opposed u-shaped contacts with the adjoining sides of said contacts having inclined surfaces thereon. The actuator arm is moveable along these inclined surfaces to open and close the contacts as needed. A blocking or shield member is pivotally mounted between the sides of each contact to further resist insertion of foreign objects or an electrical plug into the contact without first moving the actuator arm. In the preferred embodiment, the actuator arm includes a spring having a stiff bias which makes movement of the actuator arm difficult for small children. The invention is also disclosed in a further embodiment wherein it is used in an electrical extension cord application.

    Abstract: An electrical connector includes a plug having a number of contact pins and a jack having a number of receptacle contacts corresponding to the contact pins. Each of the receptacle contacts has a parallel portion and a widened portion. A contact pressing member having partition walls is movable in such a manner that, when the contact pressing member is in a first position, the partition walls are positioned at the parallel portions of the receptacle contacts to allow an easy insertion of the contact pins. When the contact pressing member is moved to a second position, the partition walls are moved to the widened portions of the receptacle contacts so that the gaps between the widened portions are narrowed. Therefore, the receptacle contacts are pressed into firm contact with the contact pins.

    Abstract: Testsite system for use in an integrated circuit handler, the testsite system for testing plastic leaded chip carriers (PLCC), leadless chip carriers (LCC) and other IC packages. The testsite system utilizes a pocket in a socket which is movable in frame between an insert position for the IC and a test position for the IC. The testsite includes an ejector which operates against a first spring constant and a movable pocket assembly which operates against a second spring constant. The movable pocket in the socket provides for alignment between the IC package, and the contact wires insure positive electrical integrity. The spring action provides for ejection of an IC after test from the pocket by a spring actuated ejector, as well as the socket assembly returning to a home position while carrying the ejector and IC at the same time through the second spring action. Alternate embodiments include a testsite with air chambers within and adjacent to the testsite for a controlled testsite temperature environment.
