A marker strip has a strip-shaped labelling strip formed of a first plastic material, which can be labelled on a first labelling side using a printer. A second side of the strip opposite the first side has a plurality of marker latching profiles formed of a second plastic material. The profiles are configured for latching in marker latching receptacles of serially arranged electrical devices. The marker strip has a main direction of extent and the latching profiles are arranged in the main direction of extent in a grid dimension on the second side of the labelling strip. The grid dimension in which the latching profiles are distributed on the second side of the labelling strip is smaller than or equal to 2 mm.

The invention relates to a labeling profile for marking electrical installations, comprising a labeling region which has a cover surface to be labeled, and comprising a support region which connects to the labeling region facing away from the cover surface, wherein, when viewed in a cross-section transverse to the longitudinal extension, at least sections of the support region have a smaller width than the labeling region, wherein the labeling profile has a constant cross-section when viewed along its longitudinal extension and wherein the labeling profile has spaced-apart, optically detectable position markers on at least one surface facing away from the cover surface, wherein intermediate regions are formed between the position markers and wherein the position markers have in particular reflective properties which differ from the intermediate regions.

Abstract A method for implementing wiring on a matrix of conductor connection devices such as terminal conductor connection devices for connection of the ends of a conductor to at least one series terminal block uses at least one luminous element to identify conductor connection devices which are illuminated in the matrix directly or indirectly in accordance with a wiring diagram. The conductor connection devices that are illuminated by the luminous element and that are to be interconnected are connected to conductors, the ends of which are inserted in the conductor connection devices to establish a respective conducting wiring connection.

A plug-in connector cooperating with a terminal block includes a body having a cooperation assembly mechanically securing the plug-in connector on the terminal block, the body having a compartment accommodating a fuse element, a pair of plug contacts received within the compartment, and a handle part having an actuating portion and a linking portion. The plug contacts are each connected to a terminal of the fuse element. Each of the plug contacts has a contact tongue extending outside of the compartment, the contact tongue electrically secured to a bus bar of the terminal block. The linking portion is attached to the body and extends along a linking axis parallel to an insertion axis of a pin of the cooperation assembly. The actuating portion has an actuating surface extending transversely to the insertion axis and cooperating with a marking element disposed along the actuating surface.

The middle section and the tail section are mounted in a wire inlet of a terminal device. The aid sleeve is formed with an internal guide hole. A wire collection section is disposed on one side of the head section distal from the middle section. A recessed guide channel is disposed on one side of the wire collection section proximal to the guide hole. The recessed guide channel includes two lateral outer arched channels with larger curvature radius. The two lateral outer arched channels gradually extend toward a middle bottom face to form an inner arched channel with smaller curvature radius. The recessed guide channel can gradually bind the forked conductor end section of a multi-strand conductive wire, whereby the wire can be quickly plugged into the guide hole.

One or more marking elements that can he provided with an inscription are formed on a terminal block which can be mounted on a mounting base or support rail has a housing made of plastic and at least one conductor connections formed in the housing, One or more marking recesses are formed in the housing with each marking recess being designed for the application of a corresponding marking element. The terminal block with the housing is formed by an injection molding toot One or more free spaces are formed in the region of the one or more marking recesses. One or more free spaces are sprayed with a plastic in the region of the marking recesses, whereby one or more inscribable marking elements are formed on the housing.

A marker-holder system for an electrical terminal block comprising a longitudinal marker-holder device according to a direction of extension, the marker-holder device comprising a central part with a thinned portion and a first end in the direction of extension and a second end in the direction opposite to the direction of extension, the system comprising a first fastener configured to be disposed on the terminal block, the first end and/or the second end being configured to cooperate with the first fastener in a removable manner, the thinned portion being divisible.

A marker-holder system for an electrical terminal block comprising a longitudinal marker-holder device according to a direction of extension, with a first end in the direction of extension and a second end in the direction opposite to the direction of extension, the system comprising a first fastener configured to be disposed on the terminal block, the first end and/or the second end being configured to cooperate with the first fastener in a removable manner and according to a rotary connection, between a first position in which a first face of the marker-holder device is oriented towards the terminal block and a second face of the marker-holder device is oriented in a direction opposite to the terminal block, and a second position in which the first face of the marker-holder device is oriented in a direction opposite to the terminal block and the second face of the marker-holder device is oriented towards the terminal block.

Electric switchboard terminal block having a body (310) extending in a lengthwise longitudinal direction (X-X), widthwise transverse direction (Y-Y) and heightwise vertical direction (Z-Z), and comprising a front face (310a) and lateral flanks (310b) situated opposite each other in the longitudinal direction (X-X), each flank having a first seat (320) for housing a label (30), and comprising a recess (330) with a substantially trapezium-like vertical cross-section arranged in a central position in the longitudinal direction (X-X) and having a greater base open on the front face (310a) of the terminal block and smaller base open towards the inside thereof, said recess (330) having at least one further seat (331;333) for housing at least one additional label (30).

A method and device are provided for marking electrical devices which can be arranged in a row on a support rail, with the aid of a laser head, wherein the support rail is pivotable about its longitudinal axis and the laser head is guided such that it can be moved at least along the longitudinal axis of the support rail. A number of marking instructions, each including a marking content and a position and an orientation of the surface to which the marking content is to be applied are specified. An image of at least a section of the support rail and of at least one electrical device are created from an image capture device and at least one of the positions at which one of the marking contents is to be applied is corrected based on an evaluation of the image. The marking instructions are grouped into marking levels in such a way that all marking instructions of one marking level can be applied by the laser head without a movement of the laser head or the support rail. The marking levels differ in terms of spatial coordinates and/or parameters for the laser head. A first one of the marking levels is selected, and the laser head is positioned and/or the support rail is pivoted according to the spatial coordinates of the selected marking level. Markings are applied according to the marking instructions of the selected marking level with the parameters for the laser head. A next one of the marking levels for marking is selected based on the movements of the laser head and the support rail which would be necessary to enables markings according to the next one of the marking levels to be applied.
