Abstract: A protector for use with a circuit board connector having exposed terminals to be electrically connected to terminal pads on an inserted circuit board, the protector partially housing the individual terminals of the connector, thereby to maintain them separated and properly located and insulate them against distortion and damage during handling, shipping, soldering and inserting the circuit board. The protector has walls inserted between contacts, and preferably two cooperating protector halves are utilized, one inserted from each side of the connector.

Abstract: A compliant conductive pin for insertion in and making electrical connection with an internally conductively lined aperture is formed from a screw machine component by conventional machine tool operations; an axial bore is formed in the portion of the terminal to be received in the hole and material is removed from the sides of that portion sufficient to expose the internal aperture, thereby producing a fixed compliant beam in that portion.

Abstract: Either one or two separate skirts may be used as an accessory with an electrical connector part designed to be mounted on a circuit board by a screw or the like. The skirts protect the pins extending from the connector part and facilitate mounting of the connector part to the board. The skirt, designed for mounting on the far side of the connector part, has protruding bushings situated to be received in openings in the connector part and to engage the screws extending from the board such that the skirt and connector part can be mounted to the board as a unit. The second skirt, designed to be interposed between the connector part and the board, may be utilized if pin protection from both sides is required. In this case, both skirts and the connector part are mounted as a unit on the board.

Abstract: An hermaphrodite electrical connector in which the two substantially identical connector parts are adapted to be associated, after they have been located side by side and pointing in the same direction, by a flip-flop type of relative movement, that is to say, one not involving rotation of the connector units around an axis in the direction of telescoping movement of the parts. When the two connector parts are secured together the engaging contacts are substantially completely enclosed and insulated from adjacent contacts.

Abstract: The connector includes first and second axially mating parts carrying interengageable contact members. A pair of spaced flexible locking arms axially extend from the first part. Each arm includes a body portion and a locking portion, the latter having a pair of laterally extending lobes. The second part has a pair of axially extending recesses terminating in a circumferential groove in which a sleeve is rotatably mounted. The sleeve has circumferential recesses each including a nesting section and a camming section. The sleeve is biased to normally align the nesting sections with the respective axially extending recesses. To lock the parts, the body portions of arms are received in the respective axially extending recesses with the locking portions thereof situated in the respective nesting sections such that radially extending shoulders at either side of the axially extending recesses engage the lobes.

Abstract: The tube socket is especially adapted for use with a longitudinal extending cathode ray tube of the type having one or more high voltage pins and a plurality of relatively low voltage pins. The socket provides structure for spark gap grounding of the high voltage pin or pins, with or without spark gap grounding of the low voltage pins, the latter spark gap protection being essentially conventional. The structure is inexpensive and easy to mold and assemble as compared with prior art socket structures performing the same or equivalent functions.

Abstract: A tube socket is especially adapted for use with a longitudinally extending cathode ray tube of the type having a plurality of high voltage pins and a plurality of relatively low voltage pins spaced apart, with each of the high voltage pins being encased in a protective silo. The socket includes a cap member defining a silo filler open at the bottom thereof and adapted to enter the tube silo. High voltage terminals mounted on the cap member extend into the silo fillers and are adapted to conductively receive the high voltage pins.

Abstract: A connector block having at least one internally bussed section comprises an electrically insulating housing having top and bottom faces and an electrically conductive buss contact. The housing has exposed on one face a plurality of apertures adapted to receive leads and exposed on an opposite face a plurality of first openings in line and communicating with the apertures respectively and a second opening bridging sides of and communicating with the plurality of first openings. The electrically conductive buss contact is disposed in the second opening and insertable thereinto through the opposite face. The buss contact comprises a body portion disposed in the second opening, a plurality of contact portions resiliently extending from the body portion and into the associated first openings respectively for contact with leads inserted through the associated apertures and associated first openings.

Abstract: A receptacle for a circuit chip having a plurality of exposed connection pads spaced from one another comprises a support body, a plurality of contact members adapted to be associated with the receptacle, a contact-holding element, and a contact-retaining element. Each contact member has a first stop part engaging the receptacle from one direction, thereby limiting the degree to which the contact member can move in that direction, and a second stop part engaging the contact-retaining element from the opposite direction, thereby limiting the degree to which the contact member can move in that direction. The contact-retaining element is removably mounted on the support body so that, after removal thereof, a single defective contact member may be removed from the support body for replacement without disturbing the other contact members.

Abstract: A socket for mounting a cathode ray tube having a plurality of conductive contact elements disposed about the neck thereof comprises a housing defining a central aperture extending therethrough for receipt of the tube neck, spaced conductive contacts mounted on the housing with first end portions adjacent to the central aperture for engagement with the conductive contact elements disposed about the tube neck, and a removable plug extending across and substantially completely obstructing the central aperture intermediate the first contact end portions and the plane of the housing front surface. The removable plug blocks the passage of solder from the front of the central aperture to the first contact end portions during soldering of the second contact end portions to a printed circuit board (thus preventing short circuiting of the first contact end portions), but is easily removable from the housing to enable passage of a tube neck through the central aperture.
