The invention is explained below
of an embodiment
described, which is explained in more detail with reference to the illustrations. Here show:
1 a side view of a conductor connection according to the invention with a socket contact,
2 a perspective view of the conductor connection 1 . 3 a perspective view of a contact spring, and
4 a perspective view of a contact carrier.
In 1 is a conductor connection according to the invention 1 shown in side view. The conductor connection 1 consists essentially of a contact carrier 2 and a contact spring attached to it 3 , The contact carrier 2 has an essentially U-shaped contour. The one U-leg is used as a fastening leg 4 formed, which is substantially perpendicular to the U-bottom 5 of the contact carrier 2 runs. On this mounting leg 4 is in the longitudinal direction of the conductor connection 6 a socket contact 7 attached to form a connector. Opposite the mounting leg 4 points the contact carrier 2 an S-shaped free leg 8th on the one with the U-bottom 5 encloses an acute angle a.
On the fastening leg 4 is a hard leg 9 the contact spring 3 attached by means of a reduction so that a fixed bearing 10 arises. The hard leg 9 the contact spring 3 extends from the fixed camp 10 on the fastening leg 4 of the contact carrier 2 for the free leg 8th of the contact carrier 2 the hard leg 9 the contact spring 3 interspersed. When enforcing the free leg 8th forms the hard leg 9 an interim storage facility 11 out. The interim storage facility 11 is at the outer free end 12 of the free leg 8th educated. The interim storage facility is located here 11 above the fixed camp 10 , ie the vertical distance of the interim storage facility 11 to the U-bottom 5 of the contact carrier 2 is larger than that of the fixed bearing 10 to the U-bottom 5 , Shortly after the free leg was enforced 8th joins the hard leg 9 the contact spring 3 a bent transition element 13 which in turn in a straight spring leg 14 transforms. fixed leg 9 and feather legs 14 close an angle ( 3 of approx. 35 °. The free end of the spring leg 14 through sets the free leg a second time 8th of the contact carrier 2 and is pretensioned in the pre-assembled state shown here on the U-bottom 5 of the contact carrier 2 forming a nip 15 on.
In the perspective representation in 2 will enforce the free leg 8th of the contact carrier 2 through the contact spring 3 clarified. The flat contact spring 3 runs from the fixed camp 10 to the interim storage facility 11 story. After enforcing the free leg 8th in a first through opening 16 are transitional elements 13 and feather legs 14 the contact spring 3 divided in two such that there are two clamping ends 17 to form two independently operable terminal connections. The two clamp ends 17 of the feather leg 14 pass through second through openings 18 a second time through the free leg 8th of the contact carrier 2 through and form with the flat U-Grand 5 of the contact carrier 2 nip 15 out.
A single contact spring 3 is in 3 shown. The connecting element is clear here 19 for training the fixed camp 10 to look like a restraint. This connection lead 19 forms together with the corresponding in 4 shown warehouse opening 20 the already mentioned fixed camp 10 , The first through opening 16 and the second through hole 18 in the free leg8 of the contact carrier 2 are by a common separator 21 in the form of a cross conductor connection 22 transverse to the longitudinal direction of the conductor connection 6 running crossbar separated from each other. The bottom of this divider 21 , which are the second through openings 18 delimited towards the top, serves as a stop element 23 for limiting the spring travel of the spring leg 14 , In the first through opening 16 is a support element 24 attached in the form of a web that extends from the free leg 8th towards the mounting leg 4 of the contact carrier 2 extends and on which the fixed leg 9 the contact spring 3 rests in the assembled state. The two second through openings 18 are marked by a direction perpendicular to the conductor connection 22 extending stabilizing web 25 separated from each other. This stabilization bridge 25 serves at the same time to guide the two clamping ends 17 during their deflection. The free leg 8th also serves as a stop for a free leg side towards the socket contact 7 towards the feather leg 14 the contact spring 3 listed operating tool 33 , for example the blade of a screwdriver that is in 1 is shown in broken lines. The operating tool 33 can only go until the first turn 26 of the S-shaped free leg 8th be guided, taking that through this turn 26 formed exhaustion of the free leg 8th at the same time a safe attachment point for the operating tool 33 forms.
In 4 A contact carrier according to the invention is shown. Which is in the longitudinal direction of the conductor connection 6 extending socket contact 7 is a contact rolled out of sheet metal. It has a cylindrical contact space for receiving a corresponding plug contact 27 on that of three contact elements, namely two guide arms 28 and a spring tongue 29 is formed. The guide arms 28 are to form a receiving opening 30 connected to an open arc. The spring tongue 29 has a contact zone at its free end 31 on that in the contact space 27 protrudes. To increase the contact area of the socket contact 7 point the guide arms 28 also a spherical bead 32 on that is in the contact space 27 extends into and the contact space 27 narrow at these points. The beads opposite each other 32 are opposite the contact zone 31 the tongue 29 arranged in such a way that there is a somewhat isosceles triangle.
