Abstract:
An electrical connector assembly (10) of very low profile for interconnecting a daughter card to a mother board, mountable onto 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). Short pin sections (48) extend above the planar body section (14) of the housing and through apertures (122) of termini (120) of circuit traces (102) of a flexible circuit element (100) and soldered to said termini. Potting material embeds, seals and insulates the solder joints and short pin sections securing the flexible circuit element to the housing. Side portions (106) of the flexible circuit element extend upwardly from the housing to regions (110) of exposed trace portions (116) to be soldered to circuit traces of a daughter card (170).
Abstract:
A pair of small diameter lead assemblies as a complete electrically and environmentally sealed matable high voltage connection suitable for use under rugged environmental conditions, have a plug element and a receptacle conditions, have a plug element and a receptacle element physically matable therewith. The lead assemblies can each include annular retention clips therearound enabling insertion into and retention within passageways of matable housings of a multi-terminal hybrid connector assembly, to enable certain existing connectors to be converted into use as high voltage connector assemblies for rugged conditions without housing modification. The plug has a small diameter dielectric annular shell with a socket terminal in an internal passageway; and the receptacle has a small diameter dielectric annular shell having a pin terminal in its internal passageway which is matable with the socket terminal. A forward receptacle portion of the receptacle surrounding the pin contact section snugly receives thereinto a forward reduced dimension plug portion of the plug. Spaced apart O-rings disposed along and tightly around the plug portion are compressed by the receptacle portion and assuredly seal the annular space therebetween, preventing generation of voltage discharge and minimizing corona formation thereat. The rearward passageway portions surrounding the existing conductor wires are potted to prevent voltage discharge and minimize corona formation thereat.
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 on 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 member can be bent between the cover portions.

Abstract:
An electrical circuit package comprise a stamped and formed lead frame to which is molded a dielectric housing member which includes openings having exposed electrical contacts, the housing member providing support for the lead frame. Some of the exposed contacts in the openings serve to support electrical components in the openings and to make electrical contact therewith while other of the exposed contacts in the openings electrically engage the electrical components and maintain them in the openings. Further exposed contacts electrically engage another electrical component and the housing member and the further exposed contacts maintain the other electrical component in the housing member. An electrical switch is part of the lead frame.
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.
Abstract:
A motor brush assembly comprises a stamped and formed lead frame including electrical terminals at spaced locations and a dielectric housing member secured onto the lead frame with the electrical terminals being exposed and accessible for electrical termination to electrical power wires and lead wires of capacitors and inductors. Cavities are located in the housing member in which the inductors are disposed. Metal brush holders are positioned in brush holder locations on the housing member and lugs thereof are electrically stapled onto the lead frame. Openings are located in the housing member exposing severable sections of the lead frame separating the lead frame into separate brush circuits. If inductors are to be disposed in the circuit path between the terminated power leads and the brush holder locations, the respective severable sections are also severed which interconnect the lead frame between the associated pairs of terminals corresponding to each inductor. A ground terminal extends outwardly from the housing member.
Abstract:
An electrical connector in the form of a chip carrier connector comprises a dielectric frame having electrical terminal posts secured therein, top sections of the terminal posts extending above a top surface of the frame and bottom sections of the terminal posts extending outwardly from a bottom surface of the frame for insertion into respective holes in a printed circuit board, a film of dielectric material initially disposed adjacent the bottom surface of the frame and having the bottom sections of the terminal posts extending therethrough. The dielectric film is movable along the bottom sections to a position adjacent the ends of the bottom sections thereby aligning the ends of the bottom sections with the respective holes in the printed circuit board so that the bottom sections can be inserted into the respective holes.
Abstract:
An electrical switch comprises a dielectric base member having parallel stationary contact assemblies provided with aligned contact segments, each of the contact segments including an exposed contact section and a dielectric section. A spring-biased movable contact assembly is disposed between the stationary contact assemblies and includes cantilevered arcuate contact sections springably engaging respective aligned contact segments. The exposed contact sections have parallel projections and the dielectric sections have a projection along which the arcuate contact sections move, one of the parallel projections being longer so that, when the arcuate contact sections move from the contact sections onto the dielectric sections or vice versa, the arcuate contact sections engage the longer projection last or first so that an electric arc, if it occurs, will occur therebetween rather than between the short projections and the arcuate contact sections.
Abstract:
Electrical lead frames are stamped from a strip of metal, each of the lead frames including spaced metal strips extending between carrier members. Projections extend outwardly from the metal strips. A dielectric housing is molded onto each of the lead frames and includes recesses in one surface exposing respective projections and holes extending through the housing in communication with the respective projections so that the electrical leads of electronic components and electrical wires can be inserted into the holes in electrical engagement with the projections and secured therein by the projections.
