DETAILED DESCRIPTION
[0027] The conductor connection terminal 1 seen in FIG. 1 has a housing 2, in which an insulation displacement connection 3 is arranged and is essentially fixed to the housing. The insulation displacement connection 3 has contact edges 30, to which an electrical conductor can be connected using insulation displacement technology. The electrical conductor can be inserted into the housing 2 in a conductor insertion direction L. For connecting the electrical conductor to the insulation displacement connection 3, the conductor connection terminal 1 has an actuation mechanism having a manual actuating element 5, a pressure piece 4, a force accumulator 6 and a stamp 7.
[0028] The manual actuating element 5 has a handle section 50, by which the manual actuating element 5 can be grasped and moved by the user, i.e., it can be pivoted from the open position shown in FIG. 1 to a closed position explained below. The handle section 50 is connected to a pressure section 51 of the actuating element 5 which is rotatable about a rotary axis. The pressure section 51 has an eccentric actuation contour 52, via which an actuating force can be transmitted to the pressure piece 4 when pivoting the actuating element 5 into the closed position. In this way, an actuating force manually generated on the actuating element 5 can be transmitted to the pressure piece 4. The pressure piece 4 is coupled to the stamp 7 via the force accumulator 6. The actuating force transferred to the pressure piece 4 is transferred to the stamp 7 via the force accumulator 6. The stamp 7 is movably mounted in the housing 2 and is supported by one or more support springs 8 on the housing 2 or on a connected component. Via the support springs 8, the stamp 7 is force-loaded in the direction of the pressure piece 4. The actuating force in this embodiment is preferably aligned essentially perpendicular to the conductor insertion direction L.
[0029] In the example shown in FIG. 1, the stamp 7 has an force absorption side 70, via which the force transmitted by the force accumulator 6 is absorbed at the stamp 7. On the side assigned to the support springs 8, the stamp 7 has a support side 72, via which the stamp 7 is supported on the support springs 8. Between the force absorption side 70 and the support side 72, a conductor receiving channel 71 is formed into which the electrical conductor to be connected can be inserted.
[0030] FIG. 2 shows the conductor connection terminal according to FIG. 1 in a different cross-sectional view with the actuated actuating element 5, i.e., the actuating element 5 is in the closed position. In this closed position, the pressure piece 4, the force accumulator 6 and the stamp 7 are shifted downwards via the pressure section 51, counter to the force effect of the support springs 8. By means of the stamp 7, the inserted electrical conductor can then be pressed with a compressive force against the contact edges 30 of the insulation displacement connection 3, so that an electrically conductive connection between the electrical conductor 9 and the insulation displacement connection 3 is established. If, for example, the electrical conductor provided with insulation is compressed or pushed against the cutting sedges 30 of the insulation displacement connection, the contact edges penetrate the insulation of the electrical conductor 9 and contact the stranded wires or a single-wire conductor of the electrical conductor.
[0031] The support springs 8 further cause a return of the stamp 7 to the starting position according to FIG. 1 and/or FIG. 3 when the actuating element 5 moves from the closed position to the open position. Thus, the electrical conductor 9 is also moved via the conductor receiving channel 71 from the contact edges 30 and can be removed from the conductor connection terminal 1.
[0032] FIGS. 3 and 4 again illustrate the different positions of the individual components in the open position (FIG. 3) and in the closed position (FIG. 4).
[0033] FIG. 5 shows an example of a conductor connection terminal 1, which corresponds to the embodiment of FIG. 1 except for the differences explained below. In contrast to FIG. 1, the stamp 7 is designed differently, wherein the support springs 8 are also arranged in a different position. In the embodiment shown in FIG. 5, the stamp 7 on the force absorption side 70 has a radially protruding collar 73, via which the stamp 7 is mounted on the support springs 8. The support springs 8 can be supported, for example, in an area of the housing 2. In this embodiment, the stamp 7 does not have support side 72 spaced apart from the force absorption side 70 by the conductor receiving channel 71. It is conceivable that also in this embodiment the stamp may be formed with a conductor receiving channel similar to the conductor receiving channel 71 of FIG. 1.
[0034] FIG. 5 shows the conductor connection terminal, as in FIG. 1, in the open position. FIG. 6 shows a sectional view comparable to FIG. 2 in the closed position of the conductor connection terminal 1. One can see in FIG. 6 that the stamp 7, in the area lying on the electrical conductor 9, has a further difference to the embodiment of FIGS. 1 to 4, namely a conductor guide contour 74 existing on the stamp 7, which extends like a groove or channel in the longitudinal direction or in the conductor insertion direction L of the electrical conductor 9 and thereby contributes in an improved way to a centered contacting of the contact edges 30. Furthermore, contours, for example protruding edges or projections aligned transversely to the conductor insertion direction L, can be provided on the conductor guide contour 74. In the closed position, these contours press into the insulation of the electrical conductor 9, so that the conductor retention forces can be advantageously increased. It is of course possible to provide such a conductor guide contour 74 also in the stamp according to the first embodiment of the conductor connection terminal.
[0035] FIGS. 7 and 8 show, analogous to FIGS. 3 and 4, the conductor connection terminal 1 in the open position (FIG. 7) and in the closed position (FIG. 8).
[0036] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
