Abstract: An apparatus for mounting a conductor terminal including an insulated housing and a bus bar on a support rail is characterized by a solid metal contact base connected with the bus bar and adapted for electrically and mechanically connecting the bus bar with the rail. The base includes a pair of integral hook portions for clamping with the edges of the rail and at least one intermediate resilient prong extending longitudinally from the base. When the hook portions are clamped onto the rail edges, the prong is biased against the rail to retain the connector in position on the rail.

Abstract: In a measuring device which serves to measure a geometrical variable with the use of a sensor which is fed an alternating measuring current of constant amplitude by a regulated, phase-dependent current source. An alternating supply voltage and an alternating measuring voltage tapped by the sensor via a feedback path of the current source is superimposed in a superimposition stage, which belongs to the current source and downstream of which a reference element for determining the alternating measuring current is connected, to form a total voltage present at the reference element. In order to match a characteristic representing the relationship between the alternating measuring voltage and the geometrical variable to a prescribed characteristic curve, at least one of the alternating voltages fed to the superimposition stage is varied. The variation can concern both the amplitude and the phase.

The contact receptacle is rigidly locked against expansion, as in the area of the separating gap, during insertion of a contact pin between the prongs because on a receptacle wall, in the area of the separating gap, there protrudes a T-shaped cover plate for which there is provided a holding recess which adjoins an adjacent contact receptacle wall.

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: A circuit board terminal assembly includes a circuit board having a plurality of conductor strips arranged thereon and a plurality of connector and functional terminals mounted on the circuit board. The connector terminals are adapted for connection with an electrical conductor and with the circuit board conductor strips while the functional terminals are adapted solely for electrical connection with the circuit conductor strips. Thus, a functional terminal is selectively electrically connected with the connector terminals and the other functional terminals via the conductor strips. Each terminal includes on its side walls elements for mechanically connecting adjacent terminals together.

Abstract: A heavy-duty electrical plug connector is characterized by a label plate slidably connected with the connector housing for movement between retracted and extended positions. A label containing information designating the poles of the plug connector is provided on the plate. For wiring the connector, the plate is pulled to its extended or reading position wherein the labelled designations of the poles of the connector are visible. After wiring, the plate is slid beneath the housing to its retracted position where it takes up little space and where it does not interfere with wiring work on other connectors.

Abstract: In a multi-pole plug connector assembly including pin and socket housings having contact carrying inserts connected therewith, the fastening screws used to connect the inserts with the respective housings have three different head configurations to serve as coding elements for indicating proper orientation of the housings for plugging connection therebetween. One of the three different head configurations can be combined only with itself while the remaining two head configurations can be combined only with each other. A large number of coding possibilities can be obtained for a plurality of adjacent connector assemblies without increasing the space requirement of the assembly and without decreasing the number of poles or pins being connected.

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.
