Passing Through Insulation To Make Contact Patents (Class 439/426)
  • Patent number: 7699635
    Abstract: Apparatus and systems described herein provide for a randomly-accessible electrical busbar with a protective cover and an associated mating connector. Both the busbar and the associated mating connector have multiple, electrically conductive bristles protruding from a surface. The busbar is protected by a nonconductive fabric cover to reduce the risk of a person from accidentally contacting the electrically conductive bristles. A connection is made between the mating connector and the busbar by the bristles of the mating connector penetrating the protective fabric cover and interdigitating with the bristles of the busbar.

  • Patent number: 7234856
    Abstract: An electrical connector for connecting multiple light emitting diodes (LEDs) in parallel to a two-wire electrical supply bus, made up of upper and lower halves that snap together and contact pins that pass through holes in the upper half to make insulation displacement connections with the conductors of the supply bus. Assemblies including large numbers of LEDs are made by snapping connectors onto the bus, inserting contacts into the connectors, and connecting LEDs to the contact pins, although not necessarily in that order. The contact pins may be hollow to receive the LED leads. Also, the positions of the holes in the upper halves of the connectors, and therefore of the contact pins, may be staggered, so that the spacing between the contacts can be made equal to the pitch between the leads of the LEDs without spacing the conductors of the supply bus further apart.

  • Patent number: 7086870
    Abstract: A structure of an array of connectors fastened to a planar insulator, usually formed of a high temperature thermoplastic. The planar insulator has a pattern of substantially cylindrical openings formed therein into which is inserted a machined copper alloy sleeve which is plated with tin or tin-lead alloy. The sleeve itself is a hollow substantially cylindrical tube with a multi-finger spring contact inserted near one (usually called the upper end). The spring contact itself is plated with gold, tin, tin-lead or other malleable electrically conductive material. At the far end of the cylindrical tube is fixed a plug of “kraft paper” to function as a barrier, made from substantially pure wood pulp with no fillers. The cylindrical tube of the sleeve grips the kraft paper barrier sufficiently for it to remain in place during the processing cycle when the copper alloy sleeve is soldered to the circuit board.

A backing element disposed beneath the dielectric element has holes of slightly larger diameter than the apertures, the holes being aligned with the apertures so that a lip region of the flexible dielectric element overlies each hole. The socket also includes contacts disposed adjacent to the holes and apertures. The joining units on the chip assembly are of larger diameter than the apertures but smaller than the holes. When the chip assembly is engaged with the socket, the dielectric element deforms. The joining units pass through the apertures and are retained in engagement with the socket, and in electrical contact with the contacts of the socket, by the dielectric element.

  • Patent number: 5359654
    Abstract: Modules integral with the body of the assembly include one for drop wire connections, one for subscriber wire connections, one for an electronics interface, and one for a network interface device. Protective sealant material within the assembly protects contacts from corrosion and other deterioration, and from shorting. Sealant plungers and a chamber containing a compressed gas impose compressive forces upon the sealant material. Shunt plugs associated with two of the modules permit signal transmission across the modules at desired times, and when removed eliminate the possibility of a subscriber being shocked or transmitting a spark when accessing subscriber components of the assembly. The main body and the modules of the assembly preferably are integrally connected and form a unitary sealed assembly.

  • Patent number: 5312265
    Abstract: This invention provides a single type of electrical connector suitable for use with cables containing from one up to the maximum number of electrical conductors that can be accommodated by passages within the connector without impairing the ability of the connector to exclude moisture and other contaminants from the area occupied by junctions between mating pairs of conductors. This is achieved by the combination of a preformed perforated gasket and a layer of penetrable, non-self-healing, non-flowing elastomer that seals all of the passages in the connector not occupied by conductors.

  • Patent number: 5273449
    Abstract: The invention provides for a modularized terminal block and an improved method of manufacturing the modular block. The block permits the connection of a plurality of drop wires or other devices in a reversible manner through the use of a standardized plug in module configuration. The module can be optimized for a given drop wire range which then uniformly connects to the base block through a standardized demateable contact. The mateable connectors each include a collapsible container filled with a sealant material such as gel or grease and an enclosed contact. Upon mating of the contacts, the deformation of the containers maintains the sealant material under compression.

  • Patent number: 5174765
    Abstract: The connector includes a first connector member that is connected to a first conductor and includes a probe that is inserted through an insulating elastomer into a conductive elastomer which is connected to a second conductor and located in a second connector member. The connection between the probe and the conductive elastomer provides a noise-free electrical connection between the two conductors. The connector is particularly useful in the transmission of data from memories in electronic apparatus. More particularly, the connector is useful in very harsh environments such as in oil and gas wells where the environment may be conductive and it is desired to make a remote connection ot an electronic sensor and transmit the data soted therein to the surface of the well.

    Abstract: Lead terminations are provided for terminating the opposite ends of a multimeter test lead to contact devices, including a right angle banana plug contact device and an in-line test probe contact device. The test lead includes a wire having a conductor surrounded by soft easily displaced wire insulation such as silicone. Each termination includes a conductive element with a penetrating portion (such as pin portion 38 in FIG. 3, or prong 110 in FIG. 8) which is advanced into one side of the wire and which moves the wire conductor until the wire conductor moves through the opposite side of the insulation. In a right angle banana plug termination (14, FIG. 3), the contact device (20) has a pin portion (38) which penetrates through a first side of the wire insulation (32) and presses the wire conductor (30) out of an opposite second side of the insulation and against a wall of a bore in an insulative body (40).
