A battery wiring module that allows an operator to easily perform operations. A battery wiring module includes: bus bars and electrical wires, which are to be electrically connected to an on-board secondary battery; a housing that is to be attached to the secondary battery, and includes bus bar housing portions and an electrical wire housing portion that house the bus bars and the electrical wires; and a second lid for closing openings of the bus bar housing portions. Information indicators that indicate operational information (+, ?) are provided on the top and back faces of the second lid.

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 conductor connection terminal with a conductor terminal connection arranged in a housing that has a first end face designed as conductor insertion side, with at least one conductor insertion opening, and a second end face, which lies opposite the first end face, a first side face and a second side face, which lies opposite the first side face. The two side faces connect the first and the second end face to each other, and a bottom face and a top face which lies opposite the bottom face and which connects the two end faces and the two side faces to each other. A first form-fit element and a second form-fit element, spaced apart from the first form-fit element, are arranged at least on the first side face, wherein the two form-fit elements have two contours which differ from each other and which are designed to complement each other.

An interface circuit having releasable electrical connectors and as little as a single relay providing a standardized connection between panel controls intended for three-wire, two-wire or combination three-wire/two-wire control and a motor drive or motor controller. In this way, greatly simplified manufacturing of control cabinets may be provided with variations in control strategy being implemented simply by the provision of different panel controls having prewired harnesses and connectors.

The invention provides a connection head (40) for using with a supply cable for supplying power to a device, which device is within a housing. A first end (41) of the connection head is for mounting outside the housing of the device. A second end (43) of the connection head is for mounting inside the housing of the device. A closed loop antenna has at least one coil and a pair of feed lines, wherein the feed lines extend from the first end (41) to the second end (43), and the at least one coil is located within the first end (41). The connection head of the supply cable provides protection for an antenna and enables the antenna to be mounted outside the housing.

The disclosure herein includes a terminal block assembly, which terminal block assembly may include: a terminal block; and a tag removably coupled to the terminal block, wherein the tag includes: a body having an upper surface and a lower surface; a tab extending from the upper surface of the body; and a pin having a first end that is tapered, the pin extending from the lower surface of the body.
