Filed:

Apr 29, 1986

Appl. No.:

6/857209

Inventors:

Michael D. Galloway - Middletown PA

David T. Shaffer - Harrisburg PA

Assignee:

AMP Incorporated - Harrisburg PA

International Classification:

H01R 410

US Classification:

29863

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.

International Classification:

H01H 1104

US Classification:

29622

Abstract:

An electrical circuit package comprises 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. The method involves molding a dielectric housing member on the lead frame with exposed circuit path parts in openings either stamped into pairs before molding or severed into pairs after molding, and further forming ones of the pairs of exposed path parts into cantilever contact members while the others of the pairs define stationary contact members.

International Classification:

H01R 13627

US Classification:

439358

Abstract:

A circuit card assembly (10) including a circuit card such as a terminator card (12) and a holder (14), insertable into a receptacle connector (20) of a mother board. Card (12) is snapped into the holder and maintained therein so that the assembly is manipulatable as a unit. Latch arms (56, 58) along side sections (52, 54) of the holder latch the assembly into guides (16, 18) of the receptacle connector.

International Classification:

H01R 3300

US Classification:

439 34

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.

International Classification:

H01R 4300
H01R 909

US Classification:

29827

Abstract:

A connector (10) having one or more arrays of elongate cantilever beam arms (22) of contacts (20) can have contact sections (26) on free ends (24) thereof soldered to respective traces (94) of a circuit element (90), by securing a lead frame (50) to free ends (24) which includes a corresponding plurality of fingers (56) extending from a carrier strip (52). On the finger ends (58) are affixed preforms (80,82) of solder; on the carrier strip (52) is defined a thin magnetic layer, transforming the brass carrier strip into a Curie point heater. When the carrier strip is subjected to RF current, it generates thermal energy which melts the solder preforms to join the fingers first to the contact sections (26) of the connector contacts (20), and in a remote location later subjected to RF current to reflow solder preform (82) to join contact sections (26) to traces (94).

International Classification:

H01H 518

US Classification:

200 5R

Abstract:

A single in-line package switch comprises a dielectric frame along which movable electrical contact members are disposed. An electrical bus contact is mounted on support members of the dielectric frame, each of the movable contact members extending between a pair of the support members. Each of the movable contact members has a sinusoidal contact section, one end of the contact section being secured in the dielectric frame 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 pair of support members between which the contact section is disposed. A housing member is secured onto the dielectric frame with actuating sections of the actuating members being operable from one surface of the housing member to one position thereby moving the sinusoidal contact sections in electrical engagement with the bus contact and to another position thereby moving the sinusoidal contact sections free of the bus contact, the spring forces of the sinusoidal contact sections maintaining the contact sections and the actuating members in the one or the other position.

International Classification:

US Classification:

439885

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.
