  • the end of the funnel-shaped section of the conductor introduction region 30 with the larger cross-section facing the conductor insertion opening 3 can also, if desired, serve as a stop for the insulated section of the electrical conductor 5.
  • the funnel-shaped conductor insertion region 30 is composed of the insulating housing 2 and the contact frame 4 and of formed these two Baueilen, a simple and effective conductor guidance is achieved, in particular, the contact frame 4 can be very simple, compact and material-saving.
  • a pusher 21 as an actuating element with a pusher arm 23 can be seen, which is designed in one piece with the insulating material 2.
  • the pusher 21 acts on run-on slopes 12 and presses on actuation these chamfers 12 together with the leaf spring 9, ie, when pressed with a force F in the direction of the insulating 2, apart.
  • the clamping edges 10 of the leaf spring 9 are pressed apart and opened the terminal point for removing an electrical conductor 5 or plugging an electrical conductor 5, in particular a stranded conductor 5.
  • the trigger arm 23 is as shown in FIGS. 6a and 6b in one piece in the region of the housing rear side 20, preferably in its lower half facing away from the housing upper side 18, formed on the insulating housing 2.
  • the pusher arm 23 follows the contour of the insulating material housing 2, so that a first pusher arm part 24 connected to the housing rear wall 20 extends approximately in the plane of the housing rear side 20 or approximately parallel thereto.
  • the contour of the pusher arm 23 follows in the further course of the contour of the transition from the housing rear side 20 to the housing top side 18, so that a second pusher arm part 25, which is integrally connected to the first pusher arm part 24 approximately in the plane of the housing top 18 or approximately parallel thereto runs.
  • the housing rear side 20 and the housing upper side 18 are arranged at an angle to each other, preferably, the housing rear side 20 and the housing top 18 are arranged at least approximately at right angles to each other.
  • the pusher arm 23 is thus substantially formed as an angle.
  • an actuating surface 27 is integrally formed on its end facing away from the first presser arm part, which in the present embodiment is trough-shaped, but alternatively also any other desired shape, for example slit or phillips shape, can accept. It can thus be seen that the pusher 21 is arranged in a housing recess 22, which extends over the housing rear side 20 and the housing upper side 18.
  • the housing recess 22 is designed substantially as a breakthrough, so that the pusher 21 can act on the arranged in the interior of the insulating housing 2 contact frame 4.
  • the pusher 21 as an actuating element is thus integrated with its angled embodiment in the wall or surface of the insulating housing 2 and constitutes a part of the insulating housing 2 itself.
  • the pusher arm 23 and the outer surface is located substantially in the plane of the surface contour of the insulating housing 2, both in the area of the housing top 18 and in the region of the rear housing 20.
  • the pusher 21 is at least slightly opposite the housing upper side 18, as shown in FIG. 5a is recognizable.
  • the chamfers 12 of the contact frame 4 lie on the pusher 21 or more precisely on the pusher surface 26 (FIG. FIG. 7 ) and deflect the pusher 21 to the outside, so that the pusher arm 23 is under a resilient bias.
  • the actuated state is shown, in which the pusher 21 is acted upon by an actuating force F in the region of the trough-like actuating surface 27. It can be seen that the pusher arm 23 deforms substantially uniformly elastically under the actuating force F, the region of the pusher 21 with the actuating surfaces 26 being inserted between the leaf springs 9.
  • the pusher arm 23 has a substantially uniform thickness or thickness for uniform elastic deformation.
  • the pusher 21 is displaced from the position projecting beyond the housing upper side 18 into a position in which the pusher arm 23, in particular the second pusher arm part 25, dips into the insulating material housing 2.
  • the elastic bias of the pusher arm 23 is released and the pusher arm 23 subjected to a reverse tension, so that the pusher arm endeavors to move outward again in order to reach its starting position.
  • the Figures 6a and 6b represent the insulating housing 2 as a single part, in particular, the described construction of the pusher 21 and the connection of the pusher 23 to the insulating material 2 are clearly visible again. Furthermore, it can be seen that the insulating housing 2 has recesses 32 on a housing underside, into which the contact areas 16 of the contact frame 4 engage, so that these contact areas 16 can protrude beyond the housing rear side 20 and the housing front side 19 with the conductor insertion openings 3 (see also FIG FIG. 1 ). At the same time it is achieved that the housing underside of the assembled electrical terminals forms a substantially flat surface without protruding components. The insulating material housing 2 can thus extend as far as the surface of the printed circuit board 7 in the state arranged on the printed circuit board 7 or rest on the printed circuit board 7.
  • the pusher surface 26 of the pusher 21 is formed substantially wedge-shaped and acts on the corresponding inclined ramps 12 of the contact frame 4.
  • the pusher 21 with a force F on the actuating surface 27 slides the wedge-shaped pusher surface 26 on the chamfers 12, dips between the leaf springs 9 and pushes them apart.
  • the leaf springs 9 press the pusher 21 back into the starting position via the starting bevels 12 and the corresponding actuating surface 26 due to their restoring force.
  • the illustrated angular design of the pusher 21 allows a relatively long effective pusher 23 with a correspondingly long lever arm, which is particularly in confined space conditions or very small electrical terminals with small Isolierstoffgeophusen advantage. This is especially the case with miniaturized terminals made possible by the inventive design of the pusher 21 in the first place to provide an effective pusher 21 for the operation of a contact frame 4.
  • the pusher arm 23 is subjected to a bias voltage in the unactuated state, the voltage with which the pusher arm 23 is acted upon, be kept small.
  • the value of the bias voltage is relatively small, since the deflection of the trigger arm 23 in the unactuated state is also relatively small.
  • the deflection of the pusher arm 23 in the actuated position in the insulating material 2 is also not much much larger than in the unactuated state, so that the voltages which the pusher arm 23 is subjected to can also be kept relatively small.
  • the pusher 21 can be kept very small overall and thus is particularly suitable for very small-sized terminals.
  • FIG. 7 It can be seen that the arranged on the leaf springs 9 chamfers 12 abut at a sufficient deflection of the leaf springs 9 on the side walls 33 of the insulating 2 and / or one or more arranged between the poles of the Anschluß1 intermediate walls 34 of the insulating housing 2.
  • the side walls 33 and / or intermediate walls 34 thus limit a deflection of the leaf springs 9 and thus prevent them from being overloaded and thus from being able to plastically deform or break.
  • Trigger arm can be realized. Due to the limited deflection of the leaf springs 9, only a limited intermediate space can arise between two mutually associated leaf springs. If the maximum width of the portion of the pusher arm 23, which dips between the leaf springs 9 is greater than the gap between the maximum deflected leaf springs 9, the pusher 23 can be deflected only limited, so that this can not be subjected to excessive stress and breaking the pusher arm 23 is effectively avoided.
  • An overload protection for the pusher 21 or the pusher arm 23 can also be achieved by providing a stop on the section of the pusher arm 23 which dips between the leaf springs 9, which stops at a maximum deflection of the pusher arm or at a maximum insertion depth on the leaf springs 9 or rests on the run-on slopes 12, so that a further deflection of the pusher arm is prevented and damage to the pusher 21 is avoided.
