Filed:

May 3, 1991

Appl. No.:

7/700081

Inventors:

Edward K. Marsh - Kernersville NC
Keith H. Dormer - Kernersville NC

Assignee:

AMP Incorporated - Harrisburg PA

International Classification:

H01R 2500

US Classification:

439 76

Abstract:

An electrical termination connector includes a substrate mounted to an insulating housing where the substrate includes conductive paths at a front edge of the substrate interconnected to electrical traces deposited on an upper and lower surface of the substrate. The electrical traces are electrically interconnected to electronic passive devices such as resistors and capacitors to simulate an impedance load to a mateable electrical connector. The assembled substrate and housing are shielded by a front shield member having a shroud surrounding the conductive paths and by upper and lower clam shell shield members which are latched in place to the front shield member. An outer insulating housing is overmolded over the assembled shielded connector to encapsulate the upper and lower shield within the outer insulating housing. As assembled, the electrical termination connector is mateable with a complementary shielded electrical connector in a local area network to simulate the impedance of a peripheral device when the peripheral device is disconnected from the local area network. In this manner, reflection of the data signals back of the network line are prevented.

US Classification:

439 76

Abstract:

An assembly for interconnecting more than one interfacing device has a wall mountable box having cavities therein. The cavities have an open front face and at least a partially open rear face. Edge card connectors interconnectable to shielded or unshielded cable are insertable through the rear face of the wall box. A shielded cable connector portion is insertable through the front face and has an edge card mounted thereto having conductive traces interconnected to resilient terminals, the terminals accessible through the front mating face. An unshielded cable connector portion is insertable through the front mating face of a second cavity. The unshielded connector is mounted to a printed circuit board which is interconnectable with an edge card connector within the cavity. The shielded or unshielded connectors are disposed in the front mating face for interconnection with a mating shielded or unshielded connector.

Assignee:

AMP Incorporated - Harrisburg PA

International Classification:

H01R 13648

US Classification:

439607

Abstract:

A shielded electrical connector is shown which includes an insulating housing having electrical terminals for interconnection to a printed circuit board and for interconnection to a similar electrical connector. The shield member is drawn to include a shroud which covers a shroud on the insulative housing. The insulative housing includes a mounting flange including two flange ends which are profiled for receiving two U-shaped mounting clips. The U-shaped clips include two legs extending from a portion of the clip for electrical connection to a printed circuit board grounding pad. The clip also includes a threaded portion which can mount the connector to a panel and which is used for commoning the shield to the U-shaped clip.

US Classification:

439181

Abstract:

Mating plug and receptacle connectors each include electrically insulating housings and plural rows of electrical terminals. The plug connector includes two terminal supporting walls or platforms extending outwardly from the housing with terminal contact portions positioned in channels on the terminal support platforms. Each platform includes at an end thereof a groove which receives a grounding strip in the form of a drain wire, commoned to an outer shielding shell. The receptacle connector has an insulating housing having two elongate slots thereacross, adapted for receiving the terminal support walls of the plug connector, and receptacle contacts for mating engagement with the plug connector terminals. The receptacle housing includes a groove in the front face carrying a grounding strip commoned to an outer shielding shell. The plug and receptacle are matable with their respective shielding shells in mating contact with each other.

US Classification:

439610

Abstract:

This invention relates to a high density shielded electrical cable connector receptacle of the type for the transmission of signals from PCMCIA cards to network wiring. The receptacle comprises a housing insert for mounting a plurality of electrical contacts, a pair of hermaphroditic, metal shielding members adapted to lie contiguous with the housing insert, and a dielectric cover member for receiving the assembled housing insert and shielding members. The housing insert comprises a dielectric, elongated, first housing member having a connector mating portion, and a rear insert receiving portion, and a dielectric insert for receipt in the insert receiving portion. The dielectric insert includes an elongated opening through which first ends of the electrical contacts may project, and a rear contact divider characterized by a plurality of axially extending ribs along the upper and lower surfaces of said dividers, where the respective upper and lower ribs are staggered and that the opposite ends of adjacent electrical contacts are alternately arranged between adjacent ribs on the upper and lower surfaces of the divider.

US Classification:

439 79

Abstract:

An electrical connector is disclosed for mounting to a printed circuit board where the electrical connector includes electrical terminals having surface mount contacts adapted for electrical engagement against conductive pads on a printed circuit board. The electrical connector also includes front mating contact portions with lead sections intermediate the contact portions and the surface mount contact portions. An alignment tine plate is positioned over the intermediate lead portions above the surface mount contacts to correctly position the surface mount contacts in an array which corresponds to the conductive pads on the printed circuit board. The alignment plate includes elongate ribs extending from a lower surface of the plate an upper surface of the surface mount contacts, thereby spanning the entire row of contacts. To form the surface mount contacts, the alignment plate is inserted over the plurality of intermediate lead portions, and a comb-like die member is inserted above the tine plate and held in place. A further die member is movable towards the intermediate lead portions transversely thereof and bends the intermediate lead portions about the respective rib members, using the rib members as mandrels for the bending process.

Abstract:

Input/output memory cards for use with computers and computer-related equipment. The cards (10) comprise connectors (40) adapted to mate with a printed circuit board (30) interfacing data from the printed circuit board to an outside environment which will utilize the memory card, lateral receiving pockets (50) on a frame (20) in the memory card for locking the connector to the frame and providing structural integrity to the memory cards, and interlocking tabs (60) integrally disposed on the connector and further adapted to mechanically interface with the lateral receiving pockets (50) for securely locking the connector to the frame and providing structural integrity to the memory card when the connector is mounted to the printed circuit board and mated to the frame. Memory cards in accordance with the present invention have significantly improved structural integrity as compared to prior memory cards. The cards are therefore rugged and easily interchangeable with a variety of different computers and computer-related equipment, thereby reducing the overall cost to users of the memory cards.
