Definitions
- the present invention relates to a spring clip a clamp body arranged in a connection space, the front the introduction of an electrical conductor with a conductor axis held in the terminal space in a bias position and can be released after inserting the conductor into the connection space is, so that the electrical introduced into the terminal compartment Head can be clamped in a clamping position under spring force.
- Such a spring clip is for example from the DE 1 213 024 B2 known.
- the spring clamp In the spring clip of the prior art Clamping body either by inserting the conductor into the Connection room or by an external, manual operation Approved.
- the spring clamp In the first case, the spring clamp is only for Solid conductors, but not for flexible conductors, in particular Stranded wire, usable.
- the second case one-hand operation is required not possible.
- the object of the present invention is a To design the spring-cage clamp in such a way that even with flexible Ladders can be operated with one hand.
- the object is achieved in that the clamping body by an axial pull-out movement of the conductor can be released.
- the locking member is preferably spring-loaded.
- the trigger element claws during the axial pull-out movement is particularly firm with the Ladder.
- the clamping body has a cutting edge to cut through any Insulation of the conductor, stripping is unnecessary the conductor before it is inserted into the spring-loaded terminal.
- a spring terminal has a connection space 1.
- a clamp body 2 is arranged in the terminal compartment 1.
- the clamping body 2 is an inserted into the connection space electrical conductor 3 with a conductor axis 4 in a clamping position can be clamped under spring force.
- two clamping levers 5 are arranged, which over a joint 5 'are connected to each other. They are minor Movable beyond a dead center position.
- the tension levers 5 thus form a slightly obtuse opening angle ⁇ .
- the opening angle ⁇ is in the range between 180 ° and maximum 190 °.
- the opening angle ⁇ is due to the construction of the two clamping levers 5 limited to this value.
- the trigger element 6 has claws 8 at its base point 7 on.
- the claws 8 claw when trying to lead the 3rd against the insertion direction x from the connection space 1 again pull out with the conductor 3 or any insulation 3 'of the conductor 3.
- the trigger element 6 is in a point of attack 9 articulated.
- the point of attack 9 is in close to the joint 5 '. In the best case the point of attack is 9 identical to the joint 5 '.
- the trigger element 6 is operatively connected to the tension levers 5.
- the tension levers 5 By pulling the wire 3 in connection with the claws of the claws 8 in the conductor 3 or the insulation 3 'are thus the tension levers 5 after the insertion of the Head 3 in the terminal room 1 first from its rest position movable to the dead center position. This position is in FIG. 3 shown.
- the clamping body 2 has a cutting edge 10.
- FIG. 5 shows a further embodiment of an inventive one Spring clamp described.
- the clamping body 2 has a locking recess 11, by means of which the clamping body 2 in the bias position a triggerable, spring-loaded locking member 12 lockable is.
- the trigger element 6 of this spring-loaded terminal When inserting the conductor 3 into the connection space 1 is the trigger element 6 of this spring-loaded terminal also moved in the insertion direction x.
- the trigger element 6 in the conductor 3. When trying pulling the conductor 3 out of the connection space 1 is clawed the trigger element 6 in the conductor 3.
- Furthermore 5 corresponds functionally to the spring-loaded terminal Spring clamp according to Figures 1 to 4. The same elements are therefore provided with the same reference numerals.
