Abstract:
An electrical switch comprises a dielectric housing along one side of which movable electrical contact members are disposed. A stationary electrical contact is disposed along the other side of the dielectric housing. Each of the movable contact members has a curved contact section, one end of the contact section being secured in the dielectric housing as a terminal section while the free end of the contact section is disposed within a recess of an actuating member pivotally mounted on the housing with actuating sections of the actuating members being operable from one surface of the housing to one position thereby moving the curved contact sections in electrical engagement with the stationary contact and to another position thereby moving the curved contact sections free of the stationary contact, the spring forces of the curved contact sections maintaining the actuating members and the contact sections in the one or the other position. The housing includes at one switch position an arrangement to maintain one of the movable contact members in electrical engagement with the stationary contact.
Abstract:
An electrical connector for electrical connection to conductive members of a ceramic chip carrier comprises first and second dielectric frame members each of which has opposed side members in which electrical terminal posts are secured at spaced intervals with top sections extending above upper surfaces of the side members and bottom sections extending below bottom surfaces of the side members. Rail members extend between respective side members of each of the frame members so that when the frame members are nested together the rail members of one of the frame members are disposed in engagement with the rail members of the other of the frame members. Latching members on each of the frame members latch the frame members together thereby forming a chip carrier-receiving area so that the top sections of the terminal posts can be eletrically connected to respective conductive members when the ceramic chip carrier is positioned within the chip carrier-receiving area.
Abstract:
A lead frame assembly comprises a stamped and formed lead frame having spaced pairs of electrical terminals and other contact sections. Severable sections initially interconnect potential electrical circuit sections of the lead frame separating the lead frame into separate metal members defining discrete electrical circuits if severed. A dielectric covering is molded over the lead frame exposing the pairs of terminals and other contact sections for termination or electrical engagement. Openings are formed in the housing exposing the severable sections of the lead frame for severing, to be selectively severed creating separate electrical circuit sections, or to be retained unsevered, as desired. After the molding of the covering over the lead frame, the article thus fabricated can be customized by selective severing and connecting of components as desired. Thus a method has been described for making a customizable lead frame assembly.

Abstract:
An electrical connector assembly (10) of the type having a pair of mateable cylindrical plug and receptacle shells (18,22) secured together by a rotatable coupling ring (16). The connector assembly is provided with a decoupling retardation mechanism which includes engageable teeth (34) on the interior of the coupling ring (16) and a pair of leaf spring members (46,72) mounted to the plug shell (18) inwardly of the teeth (34). The leaf spring member (46,72) includes a fixed beam portion (62,82) having a projection (64,84) which engages the teeth (34). The sides of the teeth and the projection are steeper on one side than the other. The steeper side is the one which is engaged when the coupling ring (16) is rotated in the direction to decouple the shells (18,22). Accordingly, greater torque is required to decouple the shells than to couple the shells.
Abstract:
An electrical connector assembly (10) of low profile for mounting onto a mother board (150), and having a housing (12) and an array of contacts (40) having elongate pin sections (42) insertable into through-holes (156) of mother board (150). The assembly includes a thin apertured organizer (50) movable along pin sections (40) and further includes a pair of guide posts (80) affixed to the housing (12) for example and extending through larger-diametered apertures (58) through organizer flanges (60) to leading ends (84) insertable into guide holes (154) of mother board (100). Organizer (50) abuts board (15) and is thereafter urged relatively toward and against housing (12) upon full mounting, being movable along guide posts (80) and pin sections (42). The assembly is accurately positionable with respect to the through-hole array by reason of the guide post leading ends (84) being received into guide holes (154) prior to pin section leading ends (44 ) entering through-holes (156).
Abstract:
An assembly of matable connectors includes first and second connectors (10,100) each including housings (16,116) having a respective plurality of signal contacts (24,124) each having a front contact section (46,146) extending transversely of the connector's mating face (12,112) to a free end (52,152) from a bend section (44,144) adjoining the contact's body section (40,140). The front contact sections (46,146) of each associated pair extend forwardly of the respective mating faces to engage each other proximate their free ends and deflect each other rearwardly about bend sections (44,144), which results in low mating force and high cycle life. The connector housings (16,116) can include a durable latching system comprising a latch arm (18) of one connector (10) having a spaced apart pair of beams (208) having pairs of latches (210) and each being received into latching slots (252) of the other connector (100) near both lateral ends of the connectors, latching proximate both lateral ends.
Abstract:
A spring for a switch actuating assembly is of generally E-shape or sinuous configuration wherein inwardly-curved free ends of outer sections are adapted to engage the legs of a central U-shape section when the spring member is compressed, thereby limiting the movement of the outer sections and increasing the spring characteristics of the spring member. The spring can be disposed in a slide member in a housing and be movable from one selected position to another so that the spring moves a movable contact member from an electrically connected condition to a disconnected condition.
Abstract:
A connector assembly for an anti-skid hydraulic braking system comprises a bulkhead connector extending through an aperture in a sidewall of the brake fluid reservoir, a connector harness mounted along the inside of the reservoir sidewalls extending from the bulkhead connector to three solenoid assemblies mounted on the reservoir floor, and a solenoid connector one each solenoid assembly in engagement with the connector harness. The solenoids extend through floor apertures into the master cylinder to respective hydraulic lines extending to brake cylinders in the wheels, one of the solenoids handling both rear wheels. The bulkhead connector mates with a connector outside the reservoir which is terminated to a wire harness connected to the on-board microprocessor to relay current to the solenoids when data from individual wheel speed sensors is processed to determine that a particular wheel is about to skid. The solenoid for that wheel is then instantaneously actuated to momentarily decrease hydraulic pressure in that wheel's brake fluid line. The connector harness is planar and can be bent around corners between adjoining sidewalls of the reservoir. Contact sections on path members of the harness are exposed to be engaged by spring arm contact sections of the bulkhead connector and the individual solenoid connectors. The harness is made by overmolding spaced cover portions over a stamped lead frame and then severing the individual path members from each other, and the path members can be bent between the cover portions.
Abstract:
A wire length having a very small diameter is terminated to a contact member by forming a groove in the contact member, disposing the wire length entirely within and along the groove, and striking the surface of the contact on both sides of the groove deforming the sides of the groove downwardly and inwardly into the groove firmly against the wire therein. The contact members can be made in lead frames on a carrier strip and have grooves formed therein, the wire can be placed in the grooves and terminated to the contact members in an automated assembly to make, for example, fuse components where wire segments bridge gaps between associated contact sections of pairs of the contact members, and the lead frames can have housings molded thereto while on the carrier strip.
