A direct plug-in compression spring terminal includes a bus bar for contacting an electrical conductor, and a clamping spring for fastening the electrical conductor in the direct plug-in compression spring terminal, wherein the clamping spring has a clamping arm that can be pivoted in a clamping direction about a clamping axis, and an actuating device for pivoting the clamping bar. In an open state, in which the electrical conductor can be inserted into the direct plug-in compression spring terminal, the clamping arm is pivoted against the clamping direction against a restoring force of the clamping spring. In a clamping state, in which the electrical conductor is clamping in the direct plug-in compression spring terminal, the clamping arm is pivoted in the clamping direction by the restoring force of the clamping spring. In the open state, the actuating device is locked in the direct plug-in compression spring terminal and additionally clamped to the clamping arm.

A terminal block with a handle structure includes an insulation base having an accommodation space, an insertion port, and a side opening. The insulation base has a limit column and a pivot part formed in the accommodation space. A conductive terminal includes a conductive body and plural lead pins, and the conductive body is positioned in the accommodation space, and the lead pin passes out from the insulation base. An elastic plate includes an abutting arm with a curved surface, a bend section sheathing the limit column, and the abutting arm is suspended on a side of the insertion port, and a pivot of the handle structure is combined with the pivot part to make a handle protrude from the insulation base, and a pressing cam abuts against the curved surface of the abutting arm, so that the handle structure may avoid damages and provide a labor-saving effect.

In order to minimize the horizontal space requirement for releasing a vertically actuable actuator of a connection device the actuator is formed to be substantially cylindrical. Therefore, by virtue of rotation about the cylinder axis of the actuator, an electrical conductor can be released in a field-terminable manner using a screwdriver by a space-saving rotational movement of the actuator, as a result of which a space-consuming lever movement of the screwdriver which is otherwise usual in the prior art is dispensed with.

A conductor terminal having an insulating material housing and having at least one spring-loaded clamping connection in the insulating material housing and also having at least one actuation element, which is pivotably accommodated in the insulating material housing and is designed to open in each case at least one associated spring-loaded clamping connection, is described. The actuation element has two side wall portions which are spaced from one another and at least partially enter the insulating material housing with a pivot bearing region and, opposite said pivot bearing region, are connected to each other by a transverse web to form a lever arm. The pivot bearing regions of the mutually distanced side wall portions of an actuation element form an axis of rotation, about which the actuation element is pivotably mounted in the insulating material housing. An associated spring-loaded clamping connection is at least partially accommodated in the space between the pivot bearing regions of an actuation element. The pivot bearing regions have actuation portions, which in each case are designed in order to act on an associated clamping spring of a spring-loaded clamping connection as the actuation element is pivoted from a closed position into an open position. The adjacent side wall portions of two actuation elements arranged adjacently in the insulating material housing border one another directly.

A conductor terminal includes a rubber shell, control pieces, and clamping springs. A connecting section is formed in a height direction of each of the clamping springs. Each connecting section is connected between a highest position and a lowest position of each of the clamping springs. A total length of each connecting section is greater than a distance between the highest position and the lowest position of each of the clamping springs, making each connecting section more extended and disposed within the entire clamping spring. Moreover, the conductor terminal is flattened, which increases the size in the plug-in direction and significantly reduces the overall height, making the wiring connection more efficient and tighter. In this way, the conductor terminal is narrowed, and the conductor terminal product is made lighter and thinner.

A connection arrangement for connecting an electrical conductor includes: a busbar; a clamping spring, which has a retaining leg and a clamping leg, the clamping leg being transferable into a clamping position and into a release position; a conductor connection space formed between a section of the busbar and the clamping leg of the clamping spring; a displaceably arranged guide element, which is in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element; and a pivotably mounted actuating element, by which the guide element is displaceable to transfer the clamping leg of the clamping spring from the clamping position into the release position.
