  • Publication number: 20030148659
    Abstract: A connector assembly is shown which includes a receptacle connector and a plug connector assembly. The plug connector assembly is comprised of a plug housing and upper and lower flanges. The plug connector housing is spring-loaded rotationally relative to the upper and lower flanges, and includes a stop feature to orient the plug connector to the upper and lower flanges. The plug connector can rotate relative to the flanges, but there is always a home position for the plug polarized position.

  • Patent number: 5399105
    Abstract: A connector array (10) for mounting to a circuit board is disclosed including a conductive shroud (16) and two electrical connectors (12, 14). The shroud includes a conductive first plate (60) that separates the two connectors (12, 14) and the leads (34) of one connector from the leads (38) of the other connector. The shroud includes solder tails (68) that electrically engage ground circuitry on the circuit board (18). A conductive second plate (64) is spaced from and parallel to the first plate (60). Contacts (72, 80) extend from edges of each of the first and second plates and are arranged so that when memory cards (28, 30) are mated with the two connectors the contacts electrically engage outer conductive surfaces of the two memory cards. The two connectors are secured in a vertically stacked position by means of a pair of clips (50) that are in interfering engagement with openings (52) formed in outer walls of the housings of the two connectors.

  • Patent number: 5161999
    Abstract: An electricl connector (1) for mounting on a circuit board includes a housing (2) having a pair of spaced, rudimentary bottom walls (30) each having a bottom surface (31) for engaging against the circuit board. Each bottom wall (30) has formed therein, a through bore (39) opening into the bottom face (31) and also opening upwardly. A hollow board lock supported in each of the bores (39) has locking legs (37) projecting below the bottom face of the respective bottom wall (30) for insertion in a hole (H2) in a circuit board. The housing (2) has therein a header (8) carrying electrical terminals (64,66,68,70) having terminal legs (76) projecting rearwardly from the header (8) and terminating in soldering tails (78) depending below the housing for insertion in further holes (H1) in the circuit board when the bottom faces (31) of the bottom walls (30) are engaged with the circuit board.

  • Patent number: 4808125
    Abstract: An electrical connector asembly (10) for mounting to a planar surface (96) has an elongate electrically conductive diecast housing (12) having an aperture (42) therein. A drawn shell (14) having an aperture therein is received in the diecast housing aperture (42). Barbs (60, 62) engage the peripheral edge (50) of flange (46), center drawn shell (14) and assure electrical continuity between drawn shell (14) and diecast housing (12). A burr relief pocket (70) in diecast housing (12) accommodates any burrs (68) from barbs (60, 62) such that flange (46) seats against housing surface (48). A thermoplastic header insert (16) having terminal receiving passages (78) with terminals (82) secured therein is received in and secured in the drawn shell aperture. Insert (16) engages barbs (60, 62) in an interference fit and is centered and partially retained thereby.

  • Patent number: 4557543
    Abstract: An improved system is disclosed for retaining electrical terminals in associated housings. The subject retention system provides captivation of terminals in a housing in such fashion that the terminals can be mass terminated by known means and can be individually removed for repair or replacement by insertion of a simple tool. The subject retention system can best be compared to a butterfly extension on the terminal and a key hole in the connector. This serves both as orienting and stabilizing means while allowing limited float to improve matability.

  • Patent number: 4397513
    Abstract: A cartridge holder and interconnect system is disclosed formed primarily of two components, namely, a cartridge and an assembly for receiving and holding the cartridge. The holder assembly includes a housing of rigid insulative material and a connector member adapted to engage a circuit board or the like and to engage the cartridge. The holder assembly also has a replaceable face plate profiled for polarizing and keying reception of an appropriate cartridge in the housing. The face plate is detachably secured to the housing so that by simply replacing the face plate the housing can be adapted to receive different cartridges. The housing is also adapted to be situated spaced above a circuit board so as to accommodate components thereunder thereby preserving the available surface of circuit board.
