Abstract: A connector is described, of the type that has pegs for insertion in holes of a circuit board to securely hold the connector to the board, wherein the pegs can be easily installed, and they assure secure holding despite variations in circuit board thickness and moderate tolerances in the diameters of the circuit board holes. Each of the pegs (41, FIG. 4 ) has a peg body (60) with an axis (62), and a plurality of ribs (71-73) projecting radially outwardly from the periphery of the body. The pegs are constructed of material of lower hardness than the material of the circuit board, so the interference fit between the pegs and circuit board results in flattening of the tips of the ribs and/or shaving of the tips of the ribs. Each peg has a slot (66) extending from the periphery of the peg body to near the axis of the peg body, and a pair of the ribs lie on opposite sides of the slot, so radially-inward pressure on the ribs causes the slot to close slightly and allow the ribs to move radially inwardly.

Abstract: An electrical connector includes mounting posts for insertion into through-holes of a printed circuit board. The connector includes a connector housing having an upper connection surface and an lower board mounting surface. A pair of mounting posts extend from the lower mounting surface adjacent each end of the connector. Each of the mounting posts is insertable into a through-hole in the printed circuit for frictional engagement with the walls of the through-hole. The mounting posts include curved portions for engagement with the walls of the through-holes. The curved portions of the mounting posts have a radius of curvature which is substantially less than the radius of curvature of the through-holes to compensate for variations in tolerances as between the mounting post and the through-holes.

Abstract: An eyelet (64) for securing a first member (22) to a second member (12) through aligned apertures (28,30) includes a tubular shank portion (66), an inverted portion (68) at a first end of the shank portion and a generally cup-shaped portion (70) at a second end of the shank portion remote from the first end. The cup-shaped portion (70) remains outside the apertures (28,30) when the eyelet (64) is inserted therethrough and has its sidewall (76) formed with an interference portion. A tool (94) for use with the eyelet includes a plunger (82) surrounded by and slidably received in a collet (84) which is longitudinally divided into a plurality of segments. At the end of each of the collet segments there is a grip head (96) having an outer surface shaped complemental to the inner surface of the sidewall (76) of the cup-shaped portion of the eyelet.

Abstract: A panel mounted electrical connector includes a plastic housing with flexible latches that are driven inwardly as the connector is forced into an aperture in a panel and spring outwardly to engage the edge of the panel aperture to hold the connector in place. The latches include interior recesses containing surfaces engaged by an integral stop contained entirely within the profile of the recesses to limit bending of the latches and resulting failure caused by pulling loads applied to the connector. The latches and stops have a configuration facilitating the provision of applying a sealing member onto the panel and the connector.

Abstract: A connection system which includes fiber optic data links comprises a connector plug at the end of fiber optic cables and a mating header connector which house electro/optical devices and which is mounted on a printed circuit board. The header connector makes optical connections between the fiber optic cables of the plug connector and the electro/optical devices and electrical connections between the electro-optical devices and the circuitry of the printed circuit board. The header connector also includes a row of terminals for making purely electrical connections for electric cables which are terminated in the connector plug.

Abstract: A mounting plate for attachment to a wall or the like where a hole or aperture has been cut in the wall. The mounting plate comprises a generally planar base and a plurality of resilient fingers extending from one surface of the base. The fingers include a wall engaging surface facing the base to engage the back of the wall. The base has wall engaging contact areas spaced from the base and movable against a bias towards the base whereby the spacing between the wall engaging surfaces and the wall engaging contact areas is variable by movement of the wall engaging contact areas towards the base against the bias. The mounting plate in a preferred embodiment has anti-rotation means on the wall engaging contact areas to prevent movement of the mounting plate once attached to the wall.

Abstract: A coaxial outlet box which is intended to be mounted on a wall, an electrical conduit front or like support surface and which can be fastened directly to the support surface or to a conventional conduit box recessed in the surface. The outlet box includes a frame-like base plate (2); a connector holder plate (5) which is arranged at right angles to the base plate adjacent a straight edge thereof and in which one or more coaxial connectors are arranged parallel with the support surface; and a hood-like cover (1) which is constructed to protect the connection of the connectors (6) with the associated cables (7). An opening in the cover side wall (10) provides access to the connector or connectors (6) for connection to respective cables.

Abstract: A circuit board system resiliently mounts a plurality of daughter boards with high circuit interconnection density on a mother board using pairs of mating connectors having welded contact members accommodated in novel arrangements in the respective connectors to permit high density of electrical interconnection with convenience and reliability. Contact parts of substantial size are welded into contacts in one connector to detachably interconnect with contact parts of similar size in mating connector to improve interconnection releability. Novel contact arrangements permit accommodation of those parts of substantial size in the mating connectors. Sheet metal spring or post parts welded into the contacts in both connectors permit the contacts to be conveniently loaded into connector bodies and permit large numbers of contact springs or posts to be soldered to terminal pads or circuit paths on mother or daughter boards with high density.

Abstract: Connector housings having as an integral part thereof, compensators to accommodate variation in circuit board thickness to enable a plurality of connectors to be mounted thereon simultaneously. More particularly, the compensators include depending, collapsible projections on the bottom surfaces of the housings which are selectively collapsed in response to the thickness of the board at each mounting site.

Abstract: The invention concerns a hermetic coaxial connector of the type intended to be attached to a panel to ensure hermetic coaxial traverse of said panel, comprising a central conductive contact housed with interposition of an insulator in a housing, forming an external conductor, provided with means of attachment to a panel, a sealing joint between the external conductor and the panel, and an insulating glass bead sealed to the central contact and to an annular ring housed at least partly in a recess of the housing. The ring presents a staggered configuration comprising an axial annular span connected by the glass sealing bead (7) to central contact (5), an axial span in contact with a corresponding span of the housing, a radial span supported against the corresponding span of the housing and a radial span in contact with the sealing joint (11) interposed between the ring and the panel (2).
