Abstract: In an electric coupling device for covering two ranges of current intensities with one and the same casing, each terminal has a stationary conductive strip (28) and a movable yoke (48) which are mounted within a housing of the casing so as to clamp a conductor (51). The housing can also accommodate a more bulky cage-type connector. In order to guide the movable components (42, 48) of the yoke connector and the conductor (51) at the time of introduction, an adapter (52) is fitted within the housing. The adapter surrounds the yoke connector so as to close the clamping zone laterally between the conductive strip (28) and the yoke (48) and to prevent rotation of the yoke. An abutment face (61) limits the relative spacing of the yoke (48) and the strip (28) while a well (59) guides the screw head. A masking panel (71) of the adapter limits the size of the opening (17) to the strict minimum required for introduction of the conductor.

Abstract: A 3-module electrical connector custom assembled for specific applications by mating together a central module and first and second contact modules to form an insulative housing for electrical contacts. The central module has a single row of contact receptacles for housing electrical ground, voltage or signal contacts. The first and second contact modules are selected from a group of preformed contact modules having configurations of from one to three rows. By proper selection of the first and second contact modules, a 3-module electrical connector can be custom assembled to have a predetermined number of rows of contact receptacles. The total number of contact rows can be odd or even numbered, and can be symmetrical or asymmetrical with respect to the single row of contact receptacles of the central module. The 3-module electrical connector can be used for insertion mounting of the terminal portions of the electrical contacts in corresponding holes of a printed circuit board.

Abstract: This terminal base for an I/O unit includes a socket unit adapted for being mounted with several relays comprising several relay terminals. This socket unit includes several socket terminals which, when the relays are mounted to this socket unit, are contacted to the relay terminals. The terminal base also includes several I/O terminals, exposed to the outside for external connection, and connected to some of the socket terminals, and a multi wire connector, adapted to be connected to several wires for leading to a central processing unit, and having several connector terminals which are connected to some of the socket terminals. It may further include a printed circuit base board on which the I/O terminals and the socket terminals are mounted. Thereby, the manufacture and assembly of the terminal base, and of the I/O unit as a whole, are simplified and reduced in cost, while the servicability and ease of diagnosis of the I/O unit are good.

Abstract: A terminal block includes a housing adapted to be fixed to a support rail which has two flanges each with a right-angle lip along its free edge. Inside the housing are a metal bearing member which is fixed relative to the housing and a metal clamping member which is movable relative to the bearing member. Both these members have two branches. A screw passes through a bore in the bearing member. Hook faces on respective branches of the bearing member face towards the head of the screw and bearing faces on respective branches of the clamping member face away from the head of the screw. When the terminal block is mounted on a support rail at least one of the hook faces and at least one of the bearing faces bear on the rail. The clamping member is U-shaped, having a central part on the side of the bearing member opposite the head of the screw and side flanges embracing the bearing member. This central part is attached to the screw but can rotate relative to the screw.

Abstract: The disclosed embodiments represent novel compact terminal blocks and novel compact side-by-side assemblies of an elongated terminal block, a wiring channel at one side, and an electric circuit structure at its opposite side. Current paths slant prominently in traversing the terminal block, including slanted end portions of wiring from the wiring channel and slanted conductors in the terminal block. Corner recesses in a first side of the terminal block admit the slanted end portions of wiring from the wiring channel. Corner recesses in the second side of the terminal block opposite the first side contain projecting terminals for plug-in connection to companion plug-in terminals of an electric circuit structure or for soldered connection to conductors of the electric circuit structure, or the second-side recesses (in another embodiment) admit slanted end portions of wiring from a second wiring channel to the terminal block's connecting devices.

Abstract: A modular electrical connector system provides relatively high density pin out capability for high speed signal transmission and coupling while maintaining discrete wire capability. The system includes plural cable terminators, plural connector blocks, each having plural cells to receive and hold respective terminators with the contacts thereof aligned for connection with further contacts inserted to engage the same, and a frame to hold the connector blocks securely in relative position to each other. Each cable terminator includes one or more contacts for electrically connecting with the cable conductor, electrical insulating molded about the junction of the contact and conductor, and a flexible locking mechanism to facilitate locking and removal of the terminator from its connector block cell, preferably from the back thereof, without disturbing other terminators in the connector block.

Abstract: The exemplary terminal block has pairs of wire fasteners distributed in two rows, and a circuit identifier bearing circuit labels corresponding to the pairs of wire fasteners; the circuit identifier is shiftable side-to-side on the terminal block so as to overlie a selected row of wire fasteners, the other row being accessible for operation.

Abstract: A sealed electrical connector has a housing receiving terminated conductors therein, for mating to a corresponding connector. A camming member is latched to the rear of the housing with bores therethrough through which the conductors extend. Wire seals are disposed between the housing and the camming member around each conductor. A sequential latching provides a first or open position for the camming member which allows for insertion of the terminated conductors through bores of the camming member, through respective wire seals and into respective passageways of the housing wherein the terminals are seated. The camming member is then moved axially forward to a second or closed position which cams against the rear sections of the wire seals and urges and deforms them radially inwardly against the conductors so that a pressure-resistant seal is formed between the conductor, the wire seal, and the camming member. Several types of wire seals are usable with the sealed connector.

Each of the clamp members is provided with a clamp bracket having both a conductor engaging element and at least one solder connector pin. The clamp member is insertable through its solder connector end into the connector compartments of the insulating body where it is held undetachably, while the clamp bracket is subsequently inserted through a lateral opening in the insulating body in a direction opposite to the direction the conductor is inserted so that the conductor engaging element is in the clamp space. No other components or assembly steps are required to unite the conductor clamp member and clamp bracket in the insulating body, but a base plate may or may not be a part of the electrical strip.
