The invention relates to a terminal block splitter connector including an insulating housing, the first conductive metal component, the second conductive metal component, the first fixing component, the second fixing component, the first wire inlet group, the second wire inlet group, the first push button, and the second push button. The first and second push button match with the first and second conductive metal component for on-line and off-line control of the first and second conductive metal component. A conductive connection plate is installed on the bottom of the insulating housing for power connection of the first and second conductive metal component. The first and second pin group are respectively mounted on the bottom of the first and second conductive metal component. The first and second socket group are installed on the conductive connection plate and respectively correspond to the first and second pin group.

Label-holder element for electric switchboard terminal blocks (100), comprising a body (10;110;210;310;410) extending in a longitudinal lengthwise direction (X-X), transverse widthwise direction (Y-Y) and vertical thickness direction (Z-Z), with a front face (10a) provided with a seat (20) for labels (30), side faces (10b) and a rear face (10c;110c;210c;310c;410c). said seat (20) having a top edge (20a) and bottom edge (20b) arranged opposite each other in the longitudinal direction (X-X) and formed with engaging means (21,22;521,522) for a label (30), and means (40;140;240) projecting outwards from the rear face of the body (10), with an elasticity in the longitudinal direction (X-X) and suitable for coupling with means (101,100;210) for supporting the label-holder element on a terminal block (100;1100).

A method is provided for attaching a label holder to an end of an electrically conductive wire provided with a crimp contact wherein, before or during the crimping of the crimp contact onto the end of the wire, a fastening tab of the label holder composed of electrically insulating material is fastened to the crimp contact. An endless tape of label holders and a contact arrangement are also provided.

A terminal block marker designed to identify a terminal block. The terminal block marker includes a rigid base and a flexible film insert. The rigid base includes a top with a first arm having a first inwardly extending projection and a second arm having a second inwardly extending projection. The rigid base also includes a bottom with legs extending in a direction opposite the arms to hold the terminal block marker in the terminal block. A flexible film insert with identification markings is installed on the rigid base. The flexible film insert is positioned under a first projection of the first arm and rotated downward until the flexible film insert snaps under the second projection of the second arm. The first and second projections retain the flexible film insert on the rigid base to form the terminal block marker.

A hybrid contact is provided having a first contact part, which is solidly made from metal, and a second contact part in the form of a stamped and bent part, which are connected to each other in a press fit, and wherein a filament connected to a label carrier is fixed in a press fit of the contact parts.

An automatic auditing system of cabling topologies using port occupancy patterns is provided. The system includes at least one sensor to sense occupancy of each port in a panel, a memory and a controller. The memory is used to store operating instruction and pre-defined port occupancy patterns associated with the ports in the panel. The controller is in communication with the memory and the at least one sensor. The controller is configured to compare a sensed port occupancy pattern of the ports based on sensor data from the at least one sensor and an associated pre-defined port occupancy pattern from the pre-defined port occupancy patterns stored in the memory. The controller is configured to generate a mismatch message when the sensed port occupancy pattern does not match the associated pre-defined port occupancy pattern.

The present disclosure provides a connector, which relates to the technical field of electrical connection devices, so as to solve the problem of poor connection stability of connectors in existing technologies. The connector includes a mounting base and a binding post, wherein the binding post has both sides symmetrically provided with a fixed fin, the mounting base defines thereon a mounting groove for mounting the binding post, two sides of the mounting groove define a limit groove, and the fixed fin is clamped in the limit groove so as to enable the binding post to be limited to the mounting groove. The connector according to the present disclosure has good connection stability and can effectively transmit current or signal, enabling an effective cooperation between connected devices.
