Definitions
- Such Federkraftklemman are used for clamping electrical conductors and are particularly advantageous when a plurality of such Federkraftklemman still is closely installed side by side in a connector.
- DE 43 36 965 A1 shows a terminal with a double-legged clamping spring, which presses an electrical conductor to be connected in each case against a busbar and electrically conductively clamped.
- an actuating handle for the simultaneous actuation of the opposite clamping legs to open the respective clamping points.
- the actuating handle has a the respective conductor insertion channel facing, semicircular, trough-shaped surface which forms a partial wall of the respective conductor insertion channel.
- DE 100 37 191 C2 discloses a clamp with an insulating housing, in which a clamping spring actuating push-button has a trough-shaped guide surface for a electrical conductor to be inserted.
- a terminal with a arranged in a terminal housing box spring which has a clamping leg for clamping an electrical conductor. It is provided in the longitudinal direction of the clamping leg to the clamping end towards sliding actuator part having a passage for the passage of an electrical conductor.
- the passageway extends from a conductor insertion opening at the pusher end to a conductor exit opening at the inner end of the actuator.
- the passage and the conductor insertion opening of the operating part are open on one side along a longitudinal side and closed at the open side by the terminal housing.
- the connector with an insulating material and with at least one such Federkraftklemman gleich. It is proposed that at least one pusher opening in the insulating housing is provided for receiving an associated actuating pusher, wherein this pusher opening is opened in each case to an associated conductor insertion opening.
- the displaceably mounted in this handle opening actuating lever forms a part of the wall of the conductor insertion opening. This is made possible by the fact that the pusher opening is opened towards the conductor insertion opening and this open part of the pusher opening is then at least partially filled by the actuating pusher.
- the pusher opening is widened from an opening portion adjoining the conductor insertion opening to the back of the pusher opening opposite the conductor insertion opening.
- the actuating handle is adapted in cross section to the widening contour of the pusher opening.
- the actuating handle has adjacent to the electrical conductor, ie in the part which forms the wall of the conductor insertion opening with, a smaller width, as in the opposite region adjacent to the clamping spring.
- the actuating handle on the actuating surface which is opposite to the one part of the wall of the insulating housing forming surface, a recess for receiving a portion of the clamping leg.
- the clamping leg is thus introduced into this recess, which has an improved storage of the actuating handle while reducing the force acting on the adjacent insulating material force and an improved leadership on the clamping leg of the clamping spring result.
- the actuating push-button is accessible from its head end, which is accessible from the outside for displacing the actuating push-button, up to that in the interior of the insulating housing against the clamping limb Actuating surface tapers conically.
- a sufficient area at the head end for depressing the actuating handle is achieved in a reduced space requirement.
- the conical taper is optimally matched to the available space above the running obliquely to the direction of actuation and Leiterereinsteckraum clamping leg and ensures optimal actuation kinematics with low space requirement.
- the free end of the actuating pushbutton which is arranged in the interior of the insulating housing adjacent to the clamping point, a projecting, the conductor insertion opening partially with forming and an electrical conductor leading to the nip nose.
- a projecting nose forms with a conductor insertion funnel and further, in particular in conjunction with the optional recess for receiving a portion of the clamping leg has the advantage of a sufficient stiffening in the operating region, which acts on the clamping leg to contribute. The risk of bending the actuating lever is thereby reduced.
- actuating handle For improved operation of the actuating handle from the outside z. B. by a screwdriver as an actuating tool, it is also advantageous if the outside of the insulating housing towards the free end accessible an actuating recess, for. in the form of a slot or Phillips. The free end of a screwdriver can then be guided into the slot and secured by the actuating recess from slipping.
- the spring force clamping connection preferably has at least one busbar piece with a clamping section which, together with a clamping edge of the clamping leg, provides a clamping point for clamping an electrical conductor between the clamping edge and the clamping section. An inserted into an associated conductor insertion opening electrical conductor is then pressed by the force of the clamping spring against the clamping portion of the bus bar and there electrically connected to the busbar.
- the electrically conductive connection of the spring terminal connection to a printed circuit board or other electrical connection can be achieved when the busbar is electrically connected to at least one terminal contact, for example in the form of a solder pin, a Lötfahne or a plug contact. The solder pin or the solder tail protrude from the insulating material out.
- a particularly compact and clamped to the electrical conductor spring terminal connection with a simple structure can be achieved when the conductor rail piece is integral for a clamping spring and a planar clamping portion with a protrusion to form the clamping surface, a planar clamping guide portion bent planar conductor guide surface and one of the conductor guide surface has bent contact surface.
- the plant leg of the U-shaped clamping spring is at least partially against the contact surface.
- the free end of the clamping leg is directed towards the protrusion to clamp an electrical conductor between the free end of the clamping leg of the clamping spring and the protrusion of the planar clamping portion of the busbar piece.
- the busbar piece in this way forms a cage, which is closed in cross section at least partially by the clamping section, the conductor guiding surface and the contact surface, in which the U-shaped clamping spring is carried.
- This spring terminal connection is self-supporting insofar as acting on the electrical conductor clamping force is collected by the busbar piece and not transmitted to the insulating material on.
- the spring arms are bent at an angle to the plant leg or the conductor insertion direction and the extension direction of the actuating lever and extend obliquely to the plant leg in an angular range of more than 0 degrees to preferably about 45 degrees.

It can be seen that the actuating lever 15 is accessible at a head end 17 from the outside of the insulating housing 2 for moving the actuating pushbutton 15 in autismeinsteckides L from the outside.
- the head end 17 has an actuating recess 18 for receiving the free end of a screwdriver to push the actuating handle 15 by means of a screwdriver to open the nip down.
- the actuating recess 18 may be performed, for example, as a slot or Phillips.
- the actuating lever 15 is tapered from the head end 17 to the actuating surface 14 in the interior of the insulating housing 2. At least in the area of the actuating surface 14, the actuating handle 15 has a recess 19 on the rear side, which is bounded laterally by two opposite edge webs 20.

It is also clear that at the head end 17 opposite end of the actuating handle 15 is provided in the direction of a conductor insertion opening 12 protruding nose 21 on which the actuating surface 14 is present on the back.
- the actuating pushbutton 15 forms a part of the wall of the conductor insertion opening 12 together with the insulating housing 2 adjoining it, not only in the area of the projecting nose 21, but also in the area above it adjacent to the conductor insertion opening 12. This allows a very compact design of the spring terminal connection.
