  • Patent number: 5098344
    Abstract: Multiconvoluted boot seal for universal joints and other mechanisms in which convolution side walls have radial ribs formed therein to strengthen the walls to reduce wrinkling and resultant cracking at high joint angles. The ribs on one side wall are external at high joint angles and mesh with rib spaces formed by internal ribs on an adjacent side wall. This meshing reduces relative turning movement between the side walls so that abrasion and boot seal wear is reduced.

  • Patent number: 5037326
    Abstract: A lamp socket includes a housing in the form of an elastomeric grommet that passes through a round hole of a panel to mount the lamp socket to the panel. The grommet has a head at one end that has an outer diameter that exceeds the diameter of the hole and engages the back side of the panel when the head is inserted through the hole. The outer portion of the head consists of a plurality of thick oblique ribs that fold inwardly to reduce the outer diameter of the head responsive to twisting movement of the head in the hole so that a relatively low engage force passes the head through the hole. The grommet further includes a conical shoulder which sealingly engages the front side of the panel and clamps the lamp socket in place.

  • Patent number: 4981443
    Abstract: A diagnostic connector tap comprises a insulation displacement terminal which is disposed in an insulator housing which has an integrally hinged cap. The diagnostic connector tap is permanently attached to an insulated electrical cable for electrical testing of the insulated electrical cable simply by placing the cable in positioning slots of the terminal and closing the cap until it is locked in the closed position which automatically establishes an electrical connection between the terminal and the conductive core of the insulated electrical cable. The insulated electrical cable is then tested by inserting a test probe through a probe aperture which provides access to the terminal inside the closed insulator housing. The electrical connection between the terminal and the conductive core of the insulated electrical cable is preferably sealed by a sealant gel which is contained in the closed housing.
