Abstract: Contacts comprising nickel and a glass-forming additive have electrical contact properties which render them suitable as replacements for gold contacts; disclosed contacts have low contact resistance even after prolonged exposure to an oxidizing ambient. The glass-forming additive is one or several of the elements boron, silicon, germanium, phosphorus, arsenic, antimony, or bismuth, and contacts are readily formed, e.g., as layers on substrates. A crystallographically disordered structure is produced in a contact surface layer at least upon exposure to an oxidizing ambient; alternatively, such desired structure can be produced by ion bombardment and even in the absence of glass-forming additives.

Abstract: A connector for electronic parts has a plurality of electronic contacting pieces arranged on a connector body at very narrow spaces and in parallel relation with respect to one another. Each of the electric contacting pieces is provided with an insulation material attached on its outer surface facing an adjacent electric contacting piece, so that the insulation material will act to isolate adjacent electric contacting pieces. The electric contacting pieces are thus planted in the connector body without any other insulating substance than the insulation material disposed between the adjacent electric contacting pieces.

Abstract: This invention relates to an electrical connector receptacle for connecting separable conductive members where the receiving connector receptacle has at least one compliant spring member of molded thermoplastic therein and in close spatial proximity to each compliant spring member is molded a rigid protective housing-barrier which limits the deflection of the compliant spring when a mating conductive member is inserted.

Abstract: An electrical contact of the type having a square post contact section at one end and a box-like receptacle contact section at the other end matable with such a post section of a like contact, for use in stackable connectors for interconnecting printed circuit boards of a parallel array, is formed to have a square post with flat side surfaces with an originally square cross-section of dimensions matable with the box-like receptacle contact section, but the contact is modified by having the corners of the square post section smoothly rounded. The diagonal of the cross-section is thereby substantially reduced and is insertable through a through-hole of the board which has a diameter similarly substantially smaller than the diagonal of the original square cross-section, while the post section maintains side surfaces which remain substantially flat for mating with an unmodified box-like receptacle contact section.

Abstract: A nickel-plated metal terminal to be spot welded has a contact part plated with nickel and a spot welding part to be spot welded to a metal part not plated with nickel thereby improving the weld characteristic of the spot welded terminal.

Abstract: An IC socket which has contacts positioned corresponding to each pin position of an IC to be inserted and a body portion holding the contacts, characterized in that at least a part of the contact is formed of conductive resin.

Abstract: A connector for providing an electrical connection between an electrical conductor and an electrical terminal. The connector is formed by a body member having a crimpable sleeve for securing the electrical conductor. A slot is formed in the body member for extending around the post of the terminal, and at least one surface of that portion of the body member surrounding the slot is provided with a relatively high frictional surface for engagement with the terminal.

Abstract: An electrical connector includes two assemblies which are adapted to mate. Each assembly has a number of contacts mounted thereon. The respective contacts (which may be pins and resilient tongues, or hermaphroditic contacts) include separate bearing surfaces and electrical contacting portions. The bearing surfaces of the contacts are subject to the abrasive action when the connector assemblies are being coupled or uncoupled, while the electrical contacting portions are protected from abrasion and contact one another only when the two assemblies are substantially coupled together.

Abstract: A low resistance connector includes a pin and mating socket. The socket includes a central bore sized for mating engagement with one end of the pin. The socket includes a number of longitudinal slots extending into and parallel with the central bore so the central bore is surrounded by a number of flexible fingers. Intimate electrical contact between the outer surface of the pin and the internal surface of the socket bounding the central bore is achieved by annealing the fingers of the socket to a dead soft condition and by the placement of resilient snap rings around the fingers to bias the fingers against the pin.

Abstract: An improved connector assembly includes a resistor coated guide pin to facilitate coupling or decoupling a circuit card to a circuit board. A first embodiment of the pin configuration comprises a single taper pin for eliminating current surges during insertion of the pin into its associated plug. A second embodiment of the pin configuration comprises a dual taper pin having two zones of resistance for also eliminating the spark and associated high frequency noise resulting from pin insertion into or removal from the connector assembly.

Abstract: An hermetically sealed electrical feedthrough assembly including an elongated inner electrical conductor having first and second ends; a glass body hermetically sealed around one length portion of the inner conductor adjacent to the first end thereof; a metal adapter hermetically sealed around the glass body and adapted for mounting in a wall of a housing; a tubular outer electrical conductor enclosing and coaxial with another length portion of the inner electrical conductor, the outer electrical conductor being separated from the inner electrical conductor by an annular volume and having one end portion electrically connected to the metal adapter and an opposite end portion disposed adjacent to the second end of the inner electrical conductor; and electrical insulation filling the annular volume and electrically isolating the outer electrical conductor from the another length portion of the inner electrical conductor.

Abstract: A pair of elements for providing slidable electrical contact therebetween wherein the contact surface of at least one of the elements comprises a plurality of contact portions and a plurality of depressed portions in between the contact portions so that wear particles which are generated between their contact surfaces as the elements are moved relative to each other are effectively swept from between the contact surfaces into the depressed portions where they are entrapped. Such operation tends to maintain a low electrical resistance between the elements over many cycles of use.

Abstract: An electrical contact assembly comprises a wire barrel onto which an electrical conductor is connected along with a receptacle contact member covered by a stamped and formed hood member. A C-shaped section of the receptacle is frictionally secured in a bore of the wire barrel with the hood member surrounding the receptacle and being crimped onto the wire barrel. The hood has a beveled lead-in entrance to facilitate insertion of a pin contact member into electrical connection with the receptacle contact member at a substantially low insertion force.

Abstract: An electrical connector for assembly of an electronic component with two parallel rows of terminals onto a printed circuit board, the connector including an insulating block having two rows of cavities, each cavity containing a contact element introduced through an opening provided at the top of the cavity and a leg projecting at the bottom of the cavity for connection to the printed circuit board. The contact element comprises a substantially flat web portion pressing against the side of the cavity adjacent to an outer longitudinal face of the insulating block. A central part of the web portion is cut out and bent to form a contact tab extending out of the plane of the web portion. The tab is resiliently urged towards the bottom of the opposite wall of the cavity to cooperate with a male contact element which is inserted into the cavity.
