Abstract

A connection terminal includes a housing; an insertion opening, which is arranged on the housing and into which a conductor can be inserted in an insertion direction; a contact element, which is arranged on the housing and with which the conductor can be brought into contact by insertion into the insertion opening; a spring element, which is arranged on the housing, is held on the housing by a spring body, and has a resiliently movable spring leg extending from the spring body, wherein the spring leg clamps the conductor inserted into the insertion opening to the contact element in a clamping position; and an actuating element, which is arranged on the housing and can be actuated in an actuation direction to move the spring leg out of the clamping position, wherein the actuating element can be locked to the housing in an open position.

First claim

The invention claimed is:

1. A connection terminal, comprising:
a housing;
an insertion opening, which is arranged on the housing and into which a conductor can be inserted in an insertion direction;
a contact element, which is arranged on the housing and with which the conductor can be brought into contact by insertion into the insertion opening;
a spring element, which is arranged on the housing, is held on the housing by a spring body, and has a resiliently movable spring leg extending from the spring body, wherein the spring leg is configured to clamp the conductor inserted into the insertion opening to the contact element in a clamping position; and
an actuating element, which is arranged on the housing and is configured to be actuated in an actuation direction to move the spring leg out of the clamping position, wherein the actuating element is configured to be locked to the housing in an open position, in which the spring leg is moved out of the clamping position, wherein the actuating element, to move the spring leg, is configured to act on a distal end of the spring leg, the distal end being remote from the spring body,
wherein the actuating element, in the open position, is configured to be moved in a release direction transverse to the actuation direction with respect to the housing so as to release the locking between the actuating element and the housing.

2. The connection terminal according to claim 1 , wherein the actuation direction is directed obliquely with respect to the insertion direction.

3. The connection terminal according to claim 1 , wherein the actuating element is configured to engage through an opening of the contact element.

4. The connection terminal according to claim 1 , wherein the actuating element has a shaft with a head, by which the actuating element is configured to be actuated, and a foot portion remote from the head, wherein the actuating element is configured to act on the distal end of the spring leg via the foot portion.

5. The connection terminal according to claim 4 , wherein the foot portion, on a side facing the spring leg, has an abutment face, via which the foot portion abuts the spring leg.

6. The connection terminal according to claim 4 , wherein the foot portion, viewed in cross section in a pivoting plane, in which the spring leg is configured to be pivoted, is rounded on the abutment face.

7. The connection terminal according to claim 4 , wherein the actuating element, in the region of its head, has a locking projection configured to lock to an associated locking projection of the housing in the open position.

8. The connection terminal according to claim 4 , wherein the actuating element, on its foot portion, has an abutment projection, which, in cooperation with a projection of the housing, is configured to limit a movement path of the actuating element counter to the actuation direction.

9. The connection terminal according to claim 8 , wherein the abutment projection and the locking projection are arranged on different sides of the actuating element.

10. The connection terminal according to claim 1 , wherein the spring leg, in the open position, is configured to exert a spring force on the actuating element, which is directed with a first directional vector component counter to the actuation direction and with a second directional vector component transverse to the actuation direction.

11. The connection terminal according to claim 10 , wherein the second directional vector component acts in the direction of bringing the actuating element into locking engagement with the housing.
