Patent number: 5989049Abstract: A ZIF PGA socket includes a first housing and at least one second housing slidably received in the first housing. The at least one second housing defines a plurality of passageways for retaining corresponding number of contacts therein. Each contact has a first portion fixed in the passageway, a second portion fixed to a printed circuit board and a third portion deformably connected between the first portion and the second portion. When the at least one second housing is moved with respect to the printed circuit board, the third portion of the contact deforms to absorb stress to the second portion of the contact.Type: GrantFiled: December 21, 1998Date of Patent: November 23, 1999Assignee: Hon Hai Precision Ind.

Patent number: 5281160Abstract: An electrical connector for connecting a second electrical connector to a printed circuit board. The electrical connector has a housing with spring contacts. The spring contacts are adapted to be displaced by and make electrical and mechanical contact with contact pins of the second electrical connector inserted into the housing. The electrical connector further comprises a contact disconnector for moving the spring contacts away from the contact pins for easier disconnection of the second electrical connector from the electrical connector.Type: GrantFiled: November 7, 1991Date of Patent: January 25, 1994Assignee: Burndy CorporationInventors: William B.

Patent number: 5273446Abstract: An electrical connector assembly is provided having a first electrical connector and a second electrical connector. The second electrical connector has a housing with a connector receiving area and spring contacts. The first electrical connector has contacts located in the receiving area and contacting the spring contacts with suitable frictional forces and shapes at their areas of contact to provide substantially no resistance, by the contacts, to movement of the first connector out of the receiving area. This is accomplished due to geometric spring action force vector being substantially equal and opposite to the frictional force vector in the direction of movement of the first connector out of the receiving area. However, the frictional forces and spring action forces are additive during insertion of the first connector into the receiving area to thereby wipe the areas of contact between the contacts of the two connectors.Type: GrantFiled: November 2, 1992Date of Patent: December 28, 1993Assignee: Burndy CorporationInventor: William B. Walkup

Patent number: 5167512Abstract: A connector system for providing electrical connection between two mutually opposed arrays of circuit contact pads including a housing (26) having an array of cells (30) corresponding to the arrays of circuit contact pads, with each cell containing a resilient connector element (21). Connector elements (21) are formed from connector blanks (10), each having a bow-shaped body portion (12). The body portion establishes a connector axis (20) and terminates at its opposite ends (14a, 14b) in respective first and second flag members (16a, 16b) which extend axially away from the body portion in respective opposite directions and terminate in electrically conductive contact surfaces, (17a, 17b, 18a, 18b, 56) to establish conductive contact with the circuit contact pads. The body portions (12) are disposed in a serpentine, single layer configuration defining an interior region into which the flag members radially extend.Type: GrantFiled: July 5, 1991Date of Patent: December 1, 1992Inventor: William B.

Patent number: 4990095Abstract: A zero separation force electrical connector which utilizes resilient energy developed and stored during mating to demate the mated contacts and separate the connector with zero separation force. In one embodiment, the contacts of first and second housing members are mated in combination to provide the stored resilient energy for subsequent demating of the contacts and the respective housing members with zero separation force. The first housing member includes male contacts with tapered ends and the second housing member includes female contacts with spring fingers. A securing mechanism is utilized to mate the first and second housing members in combination. During mating the tapered ends of the male contacts coact with corresponding spring fingers of the female contacts, biasing the fingers outwardly, to store resilient energy therein.Type: GrantFiled: June 27, 1989Date of Patent: February 5, 1991Assignee: Augat Inc.Inventor: William B.

Patent number: 4822297Abstract: A junction block for tap-in connection to a continuous two-conductor line comprises a removably mutually engageable base and a cover, defining axially aligned wire entrance and exit apertures, and a passage admitting a plug. Conductor positioners each define a conductor path between the apertures; insulation displacement means are positioned for cooperative interaction with the positioners. Each displacement means is electrically connected with a contact spring adjacent the passage.A positioner and its cooperating displacement means together define a conductor engagement position generally on a level with the wire apertures, so that tension on the wire external to the block does not tend to pull the conductors out of the displacement means. The block has cooperating alignment means mutually engageable during assembly positively to align the positioners with the displacement means before the conductor insulation is engaged, and to prevent misassembly of the block components.Type: GrantFiled: April 22, 1983Date of Patent: April 18, 1989Assignee: Ark-Les CorporationInventors: Thomas F. Prince, Julian J. Bishop, William B. Walkup

Patent number: 4392702Abstract: A jumper adapted to electrically connect adjacent ones of an array of uninsulated conductive substantially rigid vertical pins. The jumper is formed of resilient, electrically conductive sheet material and comprises a generally vertical plate portion having a free upper lengthwise edge and two generally vertical side edges, and a pin-retaining spring portion integrally connected lengthwise to the plate portion. The jumper further provides position stabilizing means comprising two arms, each arm being integrally connected to a side edge of the plate portion and bent away from the plate portion at an angle of about ninety degrees thereto. The arms are lengthwise spaced apart by a spacing adapted to clear the outer surfaces of the two adjacent pins to be connected, whereby the arms stabilize the jumper to resist tilting thereof and to prevent shorting other adjacent conductive pins.Type: GrantFiled: April 2, 1981Date of Patent: July 12, 1983Assignee: Ark-les CorporationInventor: William B.

Patent number: 4344664Abstract: A terminal and terminal block for connecting an insulated wire to electrical circuitry, without stripping and preparing the wire. The terminal has a pair of opposing spring arms, whose parallel edges define a wire-receiving slit. The terminal block has a base, in which the terminal is provided, and a top. In a first terminal block position, base and top allow a wire to be inserted into the block and laid over the terminal. The top is movable toward the base to reach a second terminal block position in which base and top are locked together. The motion of the top relative to the base forces the wire into the terminal slit; the edges slice the insulation to make electrical contact with the wire. The terminal remains compliant over a wide range of wire sizes. A clinch spring is provided in the terminal block top and provides additional retention of the wire in the block and resistance to pulling or twisting.Type: GrantFiled: October 3, 1980Date of Patent: August 17, 1982Assignee: Ark-Les CorporationInventor: William B.
