A connection terminal for connecting an electrical conductor includes: an insulating housing having at least one conductor terminal device which in each case can be operated by an actuation element mounted in the insulating housing so as to be pivotable about a pin. The at least one conductor terminal device includes a clamping point for the electrical conductor that is formed by a contact element arranged in a stationary manner in the insulating housing and a clamping spring that is arranged in the insulating housing so as to be movable, by the actuation element, between an open position and a clamping position by a free leg of the clamping spring being articulated to the actuation element by a connecting element such that the clamping spring can be moved into the open position by a pivot movement of the actuation element in a first direction.

A conductor terminal includes at least one insulating-material housing, at least one contact insert arranged at least partially in the insulating-material housing that has at least one contact piece and at least one clamping spring. The contact piece with the clamping spring forms at least one conductor clamping point for an electrical conductor to be contacted by the conductor terminal, which electrical conductor can be acted upon by a spring force of the clamping spring. At least one actuating lever is pivotably supported in the insulating-material housing for actuating the clamping spring. The actuating lever can be pivoted from a closed position to an open position and vice versa in relation to the insulating-material housing and/or the contact piece. An electrical conductor inserted into the conductor terminal is not acted upon by the spring force of the clamping spring at the conductor clamping point at least in the open position.

Therefore, the wiring wrench (2) can be latched securely with the terminal block (1) to provide the effect of latching the terminal block (1) conveniently.

A connection box with reliable and yet inexpensive contacts for solar panels to enable the use of multiple types of passive and active covers for different functionalities in the junction box built into the panel.

A connection arrangement for connecting an electrical conductor includes: a busbar; a clamping spring including a clamping leg which transferrable 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 release element which, in the release position of the clamping leg of the clamping spring, is in engagement with the guide element. The release element, during insertion of the electrical conductor to be connected into the conductor connection space, is actuatable by the insertion such that the release element comes out of engagement with the guide element. The guide element is displaceable by a spring force of the clamping leg.

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 banana plug including a body, a male portion, a female portion, and a lever. The male portion is configured to extend from the body to electrically connect with a receptacle. In one example, the receptacle is a piece of audio/video (AV) equipment. The female portion is configured to receive a wire and/or other electrical component. The lever is configured to actuate between an open position and a closed position. In the open position, the lever is configured to actuate an internal spring to receive a wire. In the closed position, the lever is configured to release the internal spring to secure and/or retain the wire via a compression force.

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 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 of 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 an actuating element, by which the guide element is displaceable in order to transfer the clamping leg of the clamping spring from the clamping position into the release position. The clamping spring is arranged between the section of the busbar and the actuating element.

A cable connection device with a contact carrier is provided and includes at least one bus bar, a contact arm for fixing an electrical conductor between the bus bar and the contact arm, and an actuator cooperating with the contact arm. The actuator is mounted such that it can move in a guide channel in an actuation direction between a released position and an actuated position, and wherein the actuator is divided into two, into a main body and a blocking body in such a way that, in the actuated position of the actuator, the blocking body can be moved relative to the main body in a blocking direction, that is different from the actuation direction, into a recess in an inner wall of the guide channel, in order to form a rear grip to block the actuator in the actuated position.
