A system for interconnecting orthogonally disposed printed circuit boards in first and second stacks comprises first contact members on facing edges of the boards of the two stacks used to interconnect the boards. A mother board is disposed perpendicular to and between the two stacks of boards. Second contact members are disposed on the same facing edges of the boards as the first contact members. They define with the first contact members a series of first multiway plug-in connectors along the respective edge of each board in the first stack and a series of second multiway plug-in connectors along the respective edge of each board in the second stack. The mother board comprises a distribution network in the form of an array of conductive tracks assigned to distributing signals to the boards. The mother board also carries connecting contact members and distribution contact members connected to the distribution network. They are disposed transversely to the mother board and define on one side of it a set of third multiway plug-in connectors adapted to have the first connectors plugged into them. On the other side of the mother board they define a set of fourth multiway plug-in connectors adapted to have the second connectors plugged into them. These interconnect the first contact members of corresponding first and second connectors via the connecting contact members. They also connect the second contact members of each board to the distribution network via the distribution contact members.

System for interconnecting orthogonally disposed printed circuit boards

A metal junction box effects connection of a cable (13) having a grounding shield (15) surrounding insulated electrical conductors (17) which extending out from the end of the said shield, and connected to a multi-pin connector plug (10). The box is equipped with a sleeve (4) over which the grounding shield (15) is fitted and held in place around the sleeve by a ferrule (19). The box is formed by a bracket (1) consisting of a central arm (2) and two, right angle side arms (3). Two lateral covers (11), have flanges (12) orthagonal to the planes of the covers (11). The sleeve (4) is coaxial of the bracket. The bracket (1) includes on its two side arms (3) two double mounting lugs (6) against which the two covers (11) are screwed from opposite sides. The ends of the two side arms terminate in tabs (7) directed toward each other. A metal plate (9) of the connector plug ( 10) is pressed at its ends against the tabs (7). The flanges of the cover (11) overlie the edges of the bracket (1) and aligned edges of the metal plate (9). The box physically protects the conductors (17), holds the cable (13) in place and provides excellent shielding due to the good electrical contact between the grounding shield (15) and the box and the presence of the flanges (12) surrounding the edges of the bracket (1) and the metal plate (9) of the connector plug (10).

Metal junction box for plug-in multicontact connector

A connector comprises a socket and a plug. The socket is located on the edge of a printed circuit card and comprises two contact tabs at different distances from the edge. A housing is placed near the tabs to receive the plug and to hold two electrically interconnected spring contact blades in contact with the tabs. If the plug is inserted one way up into the socket, its blades are connected to respective ones of the tabs, therby establishing a connection. Alternatively, if the plug is inserted the other way up, the tabs of the socket are interconnected by the first spring contact blade of the plug, thereby establishing parallel connection.

Series/parallel electrical connector, particularly for use with

A terminal for electrically connecting electrical conductors (6) to rigid electrical terminal pins (7) comprises a plurality of U-shaped individual contacts (2). One arm (20) of each contact (2) is connected to one of the conductors (6). The other arm (23) is flat and is adapted to connect to one of the pins (7). The terminal further comprises identical contact supports (1, 1') having an internal groove (10) with a rounded bottom. It has internal compartments (12) along the lateral walls of this groove (10) and external compartments along the lateral walls of each contact support (1, 1'). The internal compartments (12) accommodate the flat contact arms (23) and the respective pins (7). The external compartments accommodate the contact arms (20) adapted to contact the conductors (6). An insulating member (3) maintains the contact supports (1, 1') in alignment. A cylindrical rotary cam (5) has two diametrically opposed longitudinal flats adapted to simultaneously urge the flat contact arms (23) into contact with respective pins (7) in a 'contact' position and to open the resulting electrical contacts in an 'idle' position.

Modular electrical connection terminal

The invention is characterized by connectors 17, 18, connected by a plug-ended cord 15, it being possible to prewire and wrap the assembly in the factory, to connect a distribution frame 11 to a connector 18. The contacts in the connectors are disposed on juxtaposed terminal strips each of which includes two rows of contacts, this allowing semiautomatic connections.
