- the clamping spring in an open position and in a closed position is transferred, wherein the clamping spring has a clamping leg for clamping a conductor inserted into the housing against the current bar in the closed position.
- a corresponding terminal in which a clamping spring by means of an actuating lever in an open position and a closed position can be transferred.
- the operating lever is pivotally mounted in the housing.
- the actuating lever has a rounded arm, by means of which the actuating lever engages the clamping spring on a formed on the clamping spring tension element to the clamping spring of the
- the structure of the clamping spring and the entire terminal is very complex and complex. Also, the convenience of connecting a conductor is reduced in such a terminal for a user.
- the invention is therefore based on the object to provide a terminal, by means of which a secure connection of a conductor with a simultaneously reduced complexity in the construction of the terminal can be achieved.
- Compressive force is applied by the actuating lever on the actuating tab.
- actuating lever on the actuating tab no tensile force, but a compressive force is applied by means of an actuating lever on the actuating tab and thus the clamping spring to open them.
- the actuating tab is arranged directly on the clamping leg of the clamping spring, so that the on the
- Actuating tab-acting force can cause a movement of the clamping leg directly without having to use independent of the clamping spring additional elements or additionally provided on the clamping spring elements. As a result, an energy loss of the acting pressure force for actuating the clamping leg of the clamping spring can be prevented.
- the terminal thus has a high efficiency, so that a high level of security when connecting and disconnecting a conductor can be achieved. Also the ease of use for a user of
- Terminal can be significantly improved. Due to the direct effect on the clamping leg on the attached thereto operating tab, the structure of the terminal can also be made less complex.
- the pressure applied to the actuating tab pressure acts preferably counter to the insertion of the conductor into the terminal and also opposite to the direction of movement of the clamping leg in the movement from the closed position to the open position. In a pivoting movement of the
- Investment limb of the clamping spring preferably remains in its position and is not moved when applying the pressure force on the actuating lug with or pivoted.
- the actuating tab is preferably arranged on one side only on the clamping leg.
- the actuating tab is preferably on a along the length of the clamping leg extending transverse side surface of the clamping leg
- the width of the terminal can be reduced.
- the actuating tab is preferably divided into two areas.
- the actuating tab has a directly arranged on the clamping leg
- connection region and a pressure region arranged on the connection region, wherein the pressure region preferably spaced from the clamping leg is trained.
- the pressure area is the area of the actuating tab on which the pressure force from the operating lever is applied to the actuating tab.
- the pressure region preferably has no direct contact with the clamping leg, but only with the connection region, which is connected to the clamping leg.
- the pressure region is preferably formed in a different plane than the
- the plane spanned by the pressure area is preferably at an angle> 0, preferably at an angle> 45 ° to that of the
- the pressure range is formed angled at an angle of 90 ° to the connection region.
- the pressure region preferably runs along the width of the clamping spring and thus transversely to the longitudinal extent of the clamping spring or the clamping leg of the clamping spring, so that the compressive force acting at an angle of 90 ° on the pressure area acts along the longitudinal extension of the clamping spring or the clamping leg of the clamping spring , A lateral tilting of the clamping spring when applying the pressure force on the
- Actuation tab can be prevented.
- Actuating tab and the clamping spring are integrally formed with each other.
- the clamping spring and the actuating tab are preferably made of a
- a pin-shaped actuating region is preferably formed on the actuating lever.
- Actuating a defined pressure force can be applied with a defined pressure point on the operating tab.
- the operating lever may be positioned to the actuating tab such that the
- Actuator lever is held in the open position self-locking. Due to the self-locking, the operating lever can remain independent in the open position and does not have to be held in position by the user.
- the self-locking is designed such that in the open position, a pressure point acting on the actuating lug when applying the pressure force by means of the actuating lever is arranged above a pivot axis of the actuating lever. As a result, a self-locking of the operating lever can be formed without much design effort.

- FIG. 2 is a schematic representation of the terminal shown in Fig. 1 in a partially sectioned view with the clamping spring in the closed position
- Fig. 3 is a schematic representation of the terminal shown in Fig. 1 in a partially sectioned view with the clamping spring in the open position, and
- FIG. 4 shows a further illustration of a part of that shown in FIG.

- the housing 10 is formed in two parts, wherein the two housing parts are detachably connected to each other via a plug or screw connection.
- a conductor insertion opening 14 is formed, via which a conductor to be connected can be inserted into the terminal 100.
- the housing 10 also has an opening 15, via which a part of the
- Operating lever 13 in particular a handle 16 for actuating the operating lever 13, protrudes from the housing 10.
- the opening 15 is formed on an upper side 17 of the housing 10.
- the clamping spring 12 a clamping leg 18 and a support leg 19, which are interconnected via an arcuate connecting portion 20.
- the clamping spring 12 is mounted in the housing 10 such that the clamping leg 18 is movable, so that the clamping spring 12 into an open position in which a conductor to be connected in the clamping spring 12 and the current bar 1 1 formed clamping space can be inserted and released , And in a closed position, in which a conductor to be connected by means of
- Clamping leg 18 is clamped against the current bar 1 1, can be transferred.
- the housing 10 has a curved inner contour 21, which is adapted to the shape of the arcuate connecting portion 20, so that the arcuate connecting portion 20 can fit snugly against the inner contour 21 and thus a fixation of the clamping spring 12 in the housing 10 can be achieved.
- Cischenkel19 is in contrast to the clamping leg 18 immovably arranged in the housing 10, so that the plant leg 19 performs no movement, but remains in its position when the clamping spring 12 is transferred to the open position and the closed position.
- a U-shaped projection 22 is arranged, which serves as a stop or push-through protection for an inserted into the housing 10 conductor. Further, the approach 22 is used to receive the current bar 1 1 by the approach 22 has an opening 23 through which the current bar 1 1 is passed, so that the current bar 1 1 rests flat against an inner side of the projection 22.
- the projection 22 is formed integrally with the clamping spring 12, wherein the projection 22 to the
- the clamping spring 12 is formed together with the projection 22 of a bent metal strip.
- an actuating tab 24 is arranged on the clamping spring 12, which is arranged on the clamping leg 18 of the clamping spring 12 such that when transferring the clamping spring 12 from the closed position to the open position, a pressure force F D from the operating lever 13 to the actuating tab 24th is applied.
- a pressure force F D from the operating lever 13 to the actuating tab 24th is applied.
