Abstract: A base part has a planar inner face, and a cover part is shiftable on the inner face between a closed position overlying and congruent with the base part and an open position exposing at least part of the inner face. A pair of parallel elongated spring elements extend parallel to the inner face in one of the parts. A pivot in the one part between the center portions carries a nonround cam for movement between a pair of end positions engaging and slightly transversely elastically deflecting the center portions and a through a center position engaging and greatly transversely elastically deflecting the center portions. The cam is connected to the other of the parts to pivot between its end positions and through the center position on displacement of the cover part between the closed position and the open position.

Abstract: A telecommunication device has a permanently mounted antenna tuned to a predetermined resonant frequency and a housing formed of a plurality of parts one of which is removable. The one removable part, which may be an original element or an aftermarket add-on, changes the resonant frequency of the antenna when fitted to the housing. An electrically conductive passive correction element fixed in the one removable housing part is positioned therein and dimensioned such that when the one removable housing part is fitted to the housing the passive correction element cancels out the effect on the resonant frequency of the antenna by the one removable housing part.

Abstract: A card holder has a dielectric base adapted to support the card and having an upstanding flange formed with two holes having outer edges spaced apart along an axis by a predetermined distance. A cover is formed with two tabs engageable through the holes and having outer edges spaced apart by slightly less than the predetermined distance. The cover outer edges are formed with respective oppositely outwardly projecting bumps. The tab has at the bumps a width slightly greater than the predetermined width. The cover is deformable such that the tabs can be forced with elastic deformation of the cover through the holes until the bumps pass through the holes. The cover is pivotal about the axis on the base when the tabs are fitted through the hole. A seat on the cover loosely holds the card on the cover limitedly pivotal relative to the cover.

Abstract: An electrical contact has a pair of arms extending generally parallel to and spaced apart transversely of an insertion direction and defining a slot open outward in the insertion direction. Each arm outer end has an end face extending at an acute angle to the direction. The end faces diverge outward from each other in the direction, and a bight interconnects the arm inner ends. The arms are limitedly elastically deformable for elastic displacement of the arm outer ends perpendicular to the direction so that a part can be pressed against the end faces to elastically spread the arm outer ends. An inner contact bump projects on each arm between the respective end face and the bight transversely of the direction into the slot. An outer bump projects on each arm from between the respective inner bump and the respective end face transversely of the direction into the slot.

Abstract: A card holder has a generally flat and rectangular plastic base fixed to a support, e.g. a printed-circuit board of a card reader, and formed centered on an axis with a pair of pivot pins. A generally rectangular and flat metal cover forming a slot dimensioned to hold the card is unitarily formed with a pair of U-shaped journals each fitting partially around a respective one of the pins and forming therewith a hinge. Thus the cover can pivot between an open position with the cover and the card in the slot partially raised from the base and a closed position with the cover and the card in the slot closely juxtaposed with the base.

Abstract: An electrical miniplug has a dielectric body formed with an upper array of coplanar seats and a lower array of seats interleaved with the upper seats and lying in a lower plane offset from the upper-seat plane. Respective upper contacts are each unitarily formed with a flat mounting region lying in a respective one of the upper seats on the upper mounting plane, a rear contact end projecting rearwardly from the respective mounting region, and a front contact end projecting forwardly from the respective mounting region. Respective lower contacts are each unitarily formed with a flat mounting region lying in a respective one of the lower seats on the lower mounting plane, a rear contact end projecting rearwardly from the respective mounting region, and a front contact end projecting forwardly from the respective mounting region. All of the front contact ends lie on a common contact plane.

Abstract: An electrical connector assembly has a socket body and a plurality of conductors having tips exposed at one side of the socket body. A dielectric plug body is formed with a row of straight and longitudinally extending guides open at a front side of the plug body. The plug body is fittable with the socket body with the guides longitudinally aligned with the socket conductors. A plurality of plug conductors each have a rear portion generally fixed in the plug body, a straight front contact portion longitudinally shiftable in a respective one of the plug-body guides, having a tip exposed at the front side, and longitudinally displaceable in the respective guide between a front position and a rear position, and a connecting portion integrally formed with the front and rear portions, extending at least partially transversely, and elastically deformable to bias the plug-conductor tips into the front positions.

Abstract: A contact assembly has a dielectric mounting block having inner and outer faces, and a conductive contact unitarily formed of elastically deformable metal. The contact has a center web set in the block, an inner leg extending from the web past the inner face and elastically deflectable toward the inner face and toward the center web, and an outer leg extending from web and elastically deflectable from an outer position spaced well outward of the outer face and spaced from the web to an inner position extending at least partially inward past the web.

Abstract: A contact assembly for a contact blade has two outer sheet-metal combs of generally identical shape and each unitarily formed with a longitudinally throughgoing base strip lying in a respective base plane and having a pair of longitudinal edges and a plurality of forks each having a pair of contact arms projecting transversely from one of the edges of the respective base strip generally parallel to each other and to the respective base plane. The arms of each fork are spaced transversely of the respective base plane from each other and define a mouth open parallel to the respective base plane away from the respective one edge. The base strips are transversely juxtaposed with the mouths aligned and forming a blade-receiving slot open parallel to the base planes and with the forks of one of the combs interleaved with the forks of the other of the combs.

Abstract: A card holder has a dielectric base fixed to a grounded support and formed with a throughgoing cutout and a conductive cover forming a slot dimensioned to hold a smart card and pivotal on the base between an open position partially raised from the base and a closed position closely juxtaposed with the base and covering the cutout. Ground contacts carried on and electrically connected to the cover are positioned to engage through the cutout directly with the base in the closed position of the cover. The cover can also be grounded via a latch that holds it in the closed position and/or the hinge it is mounted on.

Abstract: A mounting assembly has a base, a sensor support manually pivotal about an axis on the base and carrying a sensor, a plurality of contacts on the base having axially spaced inner ends juxtaposed with the sensor support, and respective cam bumps fixed on the sensor support and engageable on pivoting of the sensor support about the axis with the contacts. The base is provided with a ring in which the sensor support is journaled. This ring is unitarily formed with the base. The support is in fact journaled in the ring of the base.
