  • Patent number: 4944568
    Abstract: A connector assembly for blind mated back plane interface connections of optic fibers with active optical devices includes a shroud mounted in a back plane panel within which are received a receptacle assembly mated to connector modules. The modules, each associated with a cable of a plurality of optical fibers, subdivide the mated fibers into separately connected groups to avoid expensive tolerance requirements. The receptacle includes a housing and shims for precisely locating the active optical devices relative to the ends of the optic fibers. The interface connections are shielded from interference by conduction between the receptacle housing, a fiber termination ferrule and a rear housing and strain relief portion of each connector module.

  • Patent number: 4943248
    Abstract: A terminal is provided for receiving a blade terminal of an automotive fuse. The terminal comprises first and second U-shaped contact arms disposed in spaced relationship to define a blade receiving slot therebetween. As a result, a blade terminal inserted into the blade receiving slot will be contacted on its first side by the first U-shaped contact structure and on its second side by the second U-shaped contact structure. Each U-shaped contact structure is defined by forming the metal material of the terminal about an axis extending parallel to the plane of the metal.

  • Patent number: 4940421
    Abstract: Disclosed is an improved multi-pin type of water proof electric connector which is guaranteed free of shortcircuit between adjacent pin-and-contact piece connections even if water should invade to any pin-and-connector piece connection through the very small gap between the conductor and the insulation sheath of the wire by the capillary action. The electric connector comprises a male half having contact pieces and a female half having pin terminals in its cavity, and a seal member placed in the space which is to be formed between the outer surface of the plug housing and the inside surface of the socket housing when the male and female halves are coupled. The plug housing has a plurality of hollow protrusions each containing a contact piece, and the seal member encircles each of the protrusions, thereby sealing each pin-and-contact piece connection independently from adjacent pin-and-contact piece connections when the male and female halves are mated.

  • Patent number: 4936011
    Abstract: An improved lead insertion apparatus for randomly inserting crimped wire leads one at a time into a multicircuit connector includes a pair of elongate insertion jaws for longitudinally surrounding and gripping a crimp terminated wire lead. The insertion jaws are actuable by a gripper control between a first open position, a second intermediate gripping position wherein the jaws are axially slideable along the gripped wire lead and a third closed position wherein the jaws firmly grip the lead in a non-slideable manner. The jaws and their gripper control are mounted for axial movement along the wire lead into the insertion station. A drive for the jaws moves the jaws in their intermediate wire gripping position along the wire segment until a proximity sensor senses the tips of the jaws abutting the rear end of the crimp terminal. In response to the sensor the gripper control changes the jaws to their closed position on the wire prior to insertion.

  • Patent number: 4915641
    Abstract: A drawer connector is provided with modular components to facilitate the replacement of those portions of the drawer connector that are subject to the greatest wear. The drawer connector comprises mateable female and male panel mount drawer connector housings having mateable terminals press fit or otherwise lockingly engaged therein. The conductive leads are not permanently terminated to the terminals of the drawer connector. Rather, the conductive leads are terminated to modular connector terminals or terminal assemblies which in turn are lockingly but releasably mounted to the respective rear sides of the panel mount assemblies of the drawer connector. Thus, the panel mount assemblies can be discarded and replaced upon the damage of the frequently connected and disconnected terminals therein, while still retaining the time and labor intensive termination work on the conductive leads.

  • Patent number: 4912823
    Abstract: A termination machine for inserting wires into insulation displacement slots of terminals of an electrical connector. During each termination stroke, a connector locating member moves together with the termination blade to precisely position the connector for termination. A wire locator moves together with the termination blade and moves the wire into a guide slot in a template over the connector. When the blade, the wire and the connector are in precise alignment, the termination blade completes the termination stroke. A feed slide and pawl system moves the connector in steps equal to the terminal centerline spacing, and the feed stroke is selectively adjusted to skip voids where terminals are not to be terminated.

  • Patent number: 4907990
    Abstract: A high contact force, high elastic response range pin-receiving electrical contact is provided in a pin-receiving contact including a base portion and a pair of spaced apart cantilever beams which extend forwardly from the base to a pin-receiving end. A pair of inwardly directed contact surfaces are defined on each cantilever beam facing the opposed beam for slideably, electrically engaging an inserted pin terminal. In accordance with the invention, a resilient beam support member extends from and interconnects the pin-receiving ends of the cantilevered beams. The resilient beam support member provides a significantly improvement in the elastic response range of the pin-receiving contact by enabling each cantilevered beam to endure a greater outward displacement before a minimum yield in the beam occurs while providing a greater normal force against the pin.
