Connection device for connection of an electrical line
A connection device for connection of an electrical conductor includes: a housing which has an insertion opening for insertion of an electrical conductor; a spring element arranged on the housing, which spring element has a spring leg for locking a conductor inserted in the insertion opening; and an adjusting element which is arranged adjustably on the housing. By adjustment of the adjusting element, the spring leg is movable between a clamping position in which a conductor inserted in the insertion opening is lockable in the insertion opening, and a release position in which a conductor may be inserted into the insertion opening, or a conductor inserted in the insertion opening is releasable from the insertion opening. The spring element has an actuation section arranged on the spring leg on which the adjusting element acts during an adjustment for the movement of the spring leg.
1. A connection device for connection of an electrical conductor, comprising:
a housing which has an insertion opening for insertion of an electrical conductor;
a spring element arranged on the housing, which spring element has a spring leg configured to lock the conductor inserted in the insertion opening; and
an adjusting element which is arranged adjustably on the housing,
wherein by adjustment of the adjusting element, the spring leg is movable between a clamping position in which the conductor inserted in the insertion opening is lockable in the insertion opening, and a release position in which the conductor may be inserted into the insertion opening, or the conductor inserted in the insertion opening is releasable from the insertion opening,
wherein the spring element has an actuation section arranged on the spring leg, on which the adjusting element is configured to act during an adjustment for the movement of the spring leg, and on which a support section is formed, which is configured to bear against the spring leg at a support point when the spring leg is moved.
2. The connection device according to claim 1 , wherein the adjusting element is configured to act on the actuation section in order to move the spring leg in a direction of the release position.
3. The connection device according to claim 1 , wherein the support section is not in contact with the spring leg when the spring leg is in the clamping position, and bears against the spring leg at the support point when the spring leg moves in a direction of the release position.
4. The connection device according to claim 1 , wherein the spring leg is pivotable relative to the housing about a pivot axis running through the support point by the support section making contact at the support point.
5. The connection device according to claim 1 , wherein the actuation section is formed integrally with the spring leg.
6. The connection device according to claim 1 , wherein the actuation section is bent relative to the spring leg.
7. The connection device according to claim 1 , wherein the spring element has a retaining leg connecting to the spring leg and via which the spring element is held relative to the housing.
8. The connection device according to claim 7 , further comprising a current bar which is arranged on the housing and which forms a contact section for contact with the conductor inserted into the insertion opening and against which the spring element is supported via the retaining leg.
9. The connection device according to claim 7 , wherein the retaining leg is bent relative to the spring leg around a first bending axis, and the actuation section is bent relative to the spring leg around a second bending axis that is oriented transversely relative to the first bending axis.
10. The connection device according to claim 1 , wherein the adjusting element is arranged on the housing to be pivotable about a pivot axis.
11. The connection device according to claim 10 , wherein the adjusting element has an operative section eccentric to the pivot axis for acting on the actuation section of the spring element.
