Abstract: A filter connector is provided which securely holds each of its contacts and electrically connects a capacitor between each contact and an electrical ground, which is rugged and can be constructed at low cost. The connector includes a metal shell with a rear shell wall having holes through which the contacts pass. A group of tubular capacitors with terminals at its outside and inside are installed in the holes, and each contact passes through a central hole of a tubular capacitor. The outside terminal of each capacitor is soldered to the rear shell wall, and the inner terminal of each capacitor is soldered to a contact. The capacitor has a flange on its front end that abuts the front face of the rear shell wall, and the contact has an enlarged middle portion whose rear abuts the front of the capacitor and whose front abuts a front insulator of the connector.

Abstract: A high durability drawer connector is capable of blind mating and has a receptacle connector half having a plurality of spring arm contact terminals extending forwardly of a mating face, and a plug connector half having a like plurality of contact terminals having planar contact portions to engage the spring arm contacts upon mating. Guide pins forwardly of the plug housing enter alignment recesses of the receptacle housing and align the plug connector which is floatingly mounted to a drawer end panel. At a first unmated position the spring arms enter plug housing passageways and just engage the plug's contacts under low insertion force. A camming bearing surface on one of the plug's guide pins bears against a cooperating surface of the receptacle housing and cams the plug connector in a selected axially normal direction. The plug's contacts then firmly engage the spring arms from laterally thereof biasing them to achieve contact force, and the connectors are fully mated.

Abstract: An electrical connector system with releasable latching. The system includes a plug having an insulative body carrying at least one first terminal element connected to a conductor extending from the plug. The system also includes a receptacle having a body of insulative material defining a cavity with an open end for receiving the plug and having at least one second terminal element aligned for mating engagement with the first terminal element when the plug is received in the receptacle. The plug includes a locking ear extending laterally relative to the axial direction of the plug with the receptacle having a cantilever latch extending alongside the plug and with the free end of the latch positioned past the locking ear. The latch has a window for receiving the ear to lock the plug to the receptacle. The latch is resilient and deflectable outwardly from a locking position wherein the latch holds the ear to a release position wherein the latch is disposed out of the path of the ear.

Abstract: A manually operable releasable retention arrangement in one connector housing includes a receptacle comprised of a pair of split semi-cylindrical segments each pivotally mounted to a drive shaft and adapted to threadably engage a threaded member on a second connector housing. Rotation of the drive shaft causes the segments to interengage with the threaded member whereby to hold the housings together but rearward axial movement of a forwardly biased operating sleeve circumposed about the receptacle brings an annular groove thereon into register with outward annular ribs on the segments allowing the ribs to be received in the groove and the segments to pivot relative to their mounting whereby to release the threaded member.

The fixture has a fixed support, a vertically movable first carrier on the fixed support mounting an electronic board, a vacuum chamber for moving the first carrier, spring means for vertically moving the first carrier away from the fixed support, a second carrier mounted on the first carrier for vertical motion, a vacuum chamber for moving the second carrier relative to the first carrier downwardly toward the fixed support, and spring means connected between said first and second carriers for moving the second carrier relative to the first carrier upwardly away from the fixed support.

Abstract: A shielded connector for electrical circuits comprising a non-conducting housing containing electrically conductive terminals and an electrically conductive housing, said electrically conductive housing comprising at least two elements, each of said elements being capable of mating with the other of said elements, at least one of said elements having at least one recessed pocket having an aperture open to the exterior of said element, each of said pockets being adapted to hold a projection on a latch, the interior walls of said pocket being continuous with the exterior walls of said electrically conductive housing and either a portion of said pocket also being located in a second element or at least one wall of said pocket being contributed by a second element.

Abstract: An electrical connector housing locking feature is taught. Briefly stated, the present invention provides an improved latching arm in which the electrical connector housing utilizes a latching arm which lies in a groove formed from the outer wall of the male housing and pivots at one end thereof so as to resiliently flex toward the bottom surface of the groove. The female housing has a locking member which is engageable with a portion of the latching arm thereby allowing the male and female housings to be detachably locked together.
