A power input terminal block includes terminals received in terminal channels of a housing each having a main body defining a wire pocket receiving a supply wire and a take-off tab electrically connected to the main body. The power input terminal block includes clamp contacts coupled to the take-off tabs each having a base, a spring beam extending from the base, and a cap extending from the spring beam having a poke-in window configured to receive a take-off wire. An edge defining the poke-in window engages the take-off wire and pulls the take-off wire against the wire side of the take-off tab. The power input terminal block includes release levers coupled to the housing to move the spring beam to an extended position to allow loading and removal of the take-off wire from the clamp contact and the take-off tab.

A terminal is to be connected to a mating terminal having a flat surface portion. The terminal includes a conductive main body having an abutment surface, an annular terminal spring, the annular terminal spring being held on the abutment surface and a fastener holding the annular terminal spring on the abutment surface. The fastener includes a main body shaft being inserted into a central space of the annular terminal spring, a first end of the main body shaft being fixed to the conductive main body, and a plurality of arm portions extending outward in a radial direction of the fastener from a second end of the main body shaft, the second end being opposite to the first end, the plurality of arm portions being configured to hold the annular terminal spring at a contacting portion of the annular terminal spring, the contacting portion contacting the abutment surface.

A spring clamp for plugging onto an electrical conductor of an electric machine, having a first spring leg and a second spring leg adjoining the first spring leg. The spring legs are arranged and/or formed with respect to one another in such a way that a receiving opening for receiving the electrical conductor is formed between a free first end portion of the first spring leg and a free second end portion of the second spring leg, and the conductor is clamped between the first end portion and the second end portion. The second spring leg has a sensor holder and a spring arm with a press-on tab, a spring force is exerted by way of the spring arm such that a sensor arranged in the sensor holder is fixed in the sensor holder by way of the press-on tab, and the sensor holder is pressed onto the electrical conductor.

A protective earthing contact for connecting a protective earth line with an electrically conductive carrier element in an the electrically conducting manner, wherein the protective earthing contact has a base portion, wherein two side elements project from the base portion and a respective side element has an upper region, wherein the upper regions have a latching region for clamping the protective earthing contact onto the carrier element and wherein at least one side element has a protective earth contact element for making contact to the carrier element in an electrically conducting manner. Each of the upper regions has a contact-making region, wherein the latching region and the protective earth contact element are substantially arranged at the same height in relation to the base portion.
