Abstract: A field bus connection module for coupling a local bus conductor to an associated field bus system includes a housing formed from functionally different, alignable terminal blocks, and spacing elements. The terminal blocks comprise a feed block and a grounded conductor block. Removably connected with the housing is at least one functional printed circuit board. Removal of the functional printed circuit board necessarily interrupts a separable connection between the local bus conductor and the field bus, although the field bus continues to be connected to the functional printed circuit board.

Abstract: A terminal block assembly (1) includes ground (16), power supply (7), and control signal (8) terminal blocks adapted for mounting as a unit on a grounded mounting bar, the assembly including a power distribution terminal section (3), a control signal terminal section (4), a field bus terminal connection section (2), and upon which assembly are mounted an electronics control module (23) and an internal bus bar (5). First control signal block terminals (4a) are connected with electrical components of the system, and second control signal block terminals (4b) are connected with ground via the electronics module. Tapped plug-in connectors (17) afford connection of bridging (12) or termination (18) link devices to the second terminals, thereby to establish the internal configuration of the assembly.

Abstract: In this modular control assembly, individual bus conductor segments are integrated in modular, alignable housing blocks. The bus conductor segments have strip conductors on the upper and lower surfaces thereof. The bus conductor segments of mutually adjoining housing blocks are electrically connected by separating slide contact members. The contact members comprise a closed housing containing upper and lower contact springs for engaging the strip conductors of the bus conductor segment. The slide contact members can be pushed between an extended position in which they grasp the mutually facing ends of bus conductor segments (8) of neighboring housing blocks and a retracted position in which only one bus conductor segment is covered by the slide contact member.

Abstract: A terminal block assembly with lateral distribution of electrical power includes a plurality of terminal blocks each containing a plurality of interconnected distributor bars. At least one of the distributor bars of a first conductor is directly connected with a main internal bus bar conductor, and one or more of the remaining distributor bars are connected to the main conductor via a bridge member. Each distributor bar includes a terminal having a contact portion and a bus bar laterally spaced from the contact portion, thereby to define a plug-receiving slot therebetween which opens downwardly and receives either the main conductor or a plug-in link portion of the bridge. The contact portion of the terminal bus bars extends laterally in the direction of adjacent terminal blocks for connection with distributor bars contained within the adjacent terminal blocks, thereby providing lateral distribution of the electrical supply.

Abstract: A modular control system for connecting the electrical components of an automated system, such as switches, sensors, reactors and field units, with a master field bus system via an assembly of terminal blocks mounted on a grounded support rail, characterized in that the assembly includes a power supply terminal block, a ground terminal block, and at least one control signal terminal block for supplying control signals to control circuits carried by printed circuit boards contained within a removable electronics module. The various terminal block assemblies mounted on a given support rail are connected via internal bus bar means that is connected by a module with the master field bus.

Abstract: A modular control system for automated buildings includes an assembly of terminal blocks mounted as a unit on a mounting block for supplying electrical power and control signals to and from circuits contained in an electronics module mounted on a support rail, thereby to operate associated components of the building. The terminal block assembly includes symmetrical ground, power-supply, control-signal and end-support terminal blocks connected together as a unit. Signal feed-in occurs on both sides of an electronic module arranged on the terminal block assembly.

Abstract: A terminal block and removable electronic module assembly is provided having a movable disconnect member that is displaceable relative to the module between engaged and disengaged positions in which an electronic component carried by the module is electrically connected and disconnected, respectively, relative to terminals carried by the terminal block member. When the disconnect member is in the disconnect position, the electronic module may be tested by a test plug external of the module housing.

Abstract: A labelling device for electrical terminal blocks is characterized by a unitary labelling element including a base portion which can be connected with the insulated body of the block and a tag portion connected with the base portion in a swingable manner via a strap hinge. When the tag portion is folded to the closed position, it is connected with the base portion via a pin and aperture press-fit connection. The labelling device can be manufactured in a simple manner with a narrow design and reliably retained in the closed position, whereby it also functions to cover the access openings of the terminal block.

Abstract: A circuit board clamping assembly is characterized by connector pins (3) for the connection of the circuit board clamp to the circuit board. The clamping assembly furthermore has at least one mounting peg (8) that can be inserted in a corresponding mounting opening of the circuit board. The additional mounting peg facilitates the reliable absorption of forces, such as occur during wiring, at the conductor connections (2, 2a) of the clamping assembly and guarantees a reliable mechanical link between the clamping assembly and printed circuit board.

Abstract: A label carrier device for electrical conductors is characterized by a C-shaped rigid carrier member which, after placement on the conductor, grasps the conductor from below. The opening of the carrier member is closed with an elastic extension depending from the carrier member. The extension has a clasping member including upper and lower arms. The upper arm serves as a clamping member for clamping the conductor and also presses the lower arm toward a closed position for closing the carrier member opening.

Abstract: A conductor connection assembly includes a U-shaped receptacle into which one can insert from above a screw-clamping assembly comprising a screw, a nut threadably connected with the screw, and a wire protection part in the form of a barrel spring or collar connected with the screw. On the nut, there are provided lateral protrusions adapted to fit within corresponding recesses provided in the side walls of the U-shaped receptacle. The screw clamping mechanism and the U-shaped receptacle are locked into position since the collar includes in the upper area thereof lateral shoulder projections which abut against the side edges of the side walls of the U-shaped receptacle upon activation of the screw to displace the clamping mechanism downwardly into the receptacle.

Abstract: An assembly for supporting an electrical terminal housing on a carrier rail is provided, including a pair of slide members connected with a guide portion of the housing for sliding movement between latched and released positions. The thickness of the guide is slightly greater than the thickness of the slide members to define a gap therebetween. Each of the slide members includes a lower hook portion engaging a leg of the carrier rail when the slide members are in the latched position to connect the terminal housing with the rail, and a spring is connected with the slide members for normally biasing the hook portions toward the latched position. A first abutment is connected with the housing and a second abutment is connected with the slide members, the second abutment being normally vertically offset from the first abutment by a distance corrsponding with the thickness of the gap.
