A miniature switching device has an operating member (14) with an upstanding button (26) that can be rapidly slid in any one of four horizontal directions to close any one of four switches in a casing (12). A sheet metal conducting member (28) has a flat base portion (60) that lies in the casing under said operating member, and has four upstanding plates (62) that extend from bends (63) at the periphery of the base portion. Each plate has an upper end (81) that lies against a side of the operating member so horizontal movement of the operating member tilts a plate about a corresponding bend. Each plate has a finger (83) that extends largely horizontally from the plate and that engages a corresponding contact (56) on a bottom wall of the casing.

A pair of orthogonal coding shafts (32L,32T) are rotatably mounted in a housing (22) and have rollers (42) that engage a trackball (30), so when the trackball is rotated one or both coding shafts turns. A pinion (44) is fixed to each coding shaft to turn with it. A torsion spring (50L,50T) has one end fixed to the housing and has an opposite end that forms a contact rod (70). The contact rod has an upper end lying between teeth of the pinion so the upper end of the rod is repeatedly deflected and repeatedly snaps back to its original position. The lower end of the contact rod pivots with the upper end, so the lower end repeatedly engages and disengages a lower contact element (134L, 134T) to make and break a circuit. The lower contact element is a cantilevered pin that extends orthogonal to the control rod.

An electrical connector assembly includes two connectors (22, 24), wherein the first connector has a pair of contacts (46A, 46B, FIG. 9 ) which rapidly break engagement as the connectors slowly approach each other. An actuator (60), has a ridge deflector (72) for moving back a contact end portion (52A), the actuator being urged rearwardly (R) by a first spring (100). However, a pair of rearwardly bowed trigger springs (82) press against surfaces (96) to resist rearward (R) actuator movement. As the connectors progressively approach each other, the first spring (100) is progressively compressed, causing increasing deflection of the middles of the trigger springs (82), until resistance offered by the trigger springs suddenly decreases. The actuator then moves rapidly rearward, so its deflector (72) moves back the contact end portion (52A) to rapidly open the switch. The actuator is rapidly moved back by the now-compressed first spring (100).
摘要:
A card-edge connector support providing electric and thermal connections for cards or boards of the printed circuit type in which removal of thermal energy constitutes an essential requirement. The support comprises a common flat base adapted to carry a plurality of strip connectors placed at right angles to each other, a groove being formed in each strip for receiving one edge of the card. The opposite internal faces of the groove are adapted to carry electrical and thermal contacts respectively, the bearing force for heat transmission being obtained by elastic deformation of the electrical contacts.

A zero insertion force connector for a rectangular chip carrier and a closure clip for such a connector, comprising on the one hand a rectangular base and on the other a clip formed by a rectangular frame coming to bear on the upper part of the carrier, said clip being fixed to said base by hooks disposed at the four corners of the rectangular frame and cooperating with corresponding housings in the base. Said clip further comprises at least two oppositely disposed bearing arms connected together by two cross arms, each bearing arm comprising substantially in the middle thereof a bearing zone to which are connected two symmetrical half arms forming a V in the free condition, the ends of said half arms situated in the vicinity of said hooks being at a level higher than the bearing zone when said clip is in the free condition and substantially at the same level thereas when it is fixed to said base.

A connector having at least one contact with a resiliently deformable arm, inserted longitudinally in a socket formed in an insulating block and having longitudinal generatrices, and comprising: a body cooperating with at least one edge of the socket so that, once the contact has been inserted, it has a longitudinal axis substantially parallel to the direction of the generatrices of the socket; an output terminal disposed at a longitudinal end of the body of the contact and extending beyond the socket; an extention forming an abutment for the contact on the insulating block in the direction of insertion of the contact; and a resilient tongue cooperating with a stopping face of a retention cavity disposed in the socket so as to form an abutment in the direction opposite the direction of insertion of the contact; the resiliently deformable arm being disposed at the other longitudinal end of the body and extending beyond the socket.

A control includes a drum (36) that is rotatably mounted in a housing (22), and includes devices for generating signals to indicate the direction in which the drum is turning and for generating signals to indicate which end of the drum is depressed. A gear (100) is fixed to the drum, and as the drum rotates a deflectable contact element (T6) is repeatedly deflected by teeth of the gear to repeatedly engage a stationary contact (T4, T5). The deflectable contact element is in the form of a wire with a deflectable part (104) deflected by gear teeth, a mount part (110) mounted on the housing, and a contacting part (108) that repeatedly engages the stationary contact, all being part of the wire. Depression of one end of the drum results in depression of a corresponding end of a sheet metal trigger member (30) that is free to snap down against a stationary contact (T2, T3). Stationary contacts that are repeatedly contacted, are in the form of wires with fixed first end and with free or fixed second ends.

A smart card connector with a slot into which a smart card can be inserted, includes a slide assembly (251, FIG. 10) that initially receives the smart card and moves the card forward to a fully installed operating position, and that later moves the smart card a distance rearward to a retracted position and allows the rear card end to be easily pulled out of the connector. The slide assembly includes a card holding slider (500) that includes a sheet metal plate that lies under the card, and a retention bar (524) at the rear end of the plate that abuts the rear edge of the card. When the slider has been moved rearward to a retracted position, the retention bar can be lowered by bending the sheet metal plate, so the card can be grasped and pulled out. The slide assembly also includes a slidable carriage (250) that is mounted at one side of the card-receiving slot and connected to the slider to move with it, that is urged rearward by a coil spring (254), and that is coupled to a double click mechanism on the housing.

A connector with a cover element (80) lying in a forward position over an insulative support (40), allows a smart card to be inserted despite obstructions lying closely behind the connector. The card is initially inserted at a downward-forward incline and then its rear is pushed down so the card is horizontal. Then the cover element is slid to a rearward position to prevent card tilt. Contact blades (70) have upwardly biased contact ends (72) that lie substantially in a single transverse plane (Pv) and engage a single row of card contact pads at the front of the card. This allows the cover element rear position to lie only a short distance rearward of its front position so the support supports less than half the card length, thereby allowing a short support to be used. The cover element has a rear portion (85) bent at a rearward-upward incline and forming a convex lower rear face part (A).
