Device for producing and removing an electrical plug connection
View Patent ↗One plug connecting element is mounted on its device part in a side wall of a recess. The other plug connecting element is mounted on a swivel holder. When the one device part is inserted into the other device part, the swivel initially pushes the other plug out of the way of the one device part as it is being inserted. Further insertion causes the swivel holder to move the other plug into the recess in a position to mate with the one plug.
1. A device for establishing and disconnecting an electrical plug connection, said device comprising a first plug connecting element and a second plug connecting element of which are connected to each other on device parts when the latter are brought together, wherein the device parts can be moved relative to each other with restricted guidance and are guided against each other, as well as are separated from each other when the device parts are separated, in particular for electrically contacting circuits of a plug-in device with circuits of a device frame receiving the plug-in device, wherein
the first plug connecting element is held at the first device part in a connecting position in which it is aligned with the second plug connecting element is the second connecting element being stationarily arranged in a recess in a longitudinal side wall of the second device part extending in sliding direction, and that when separating the first device part and second device part by sliding them relative to each other, the first plug connecting element being moved out of alignment with the second connecting element by the second device part contacting a spring connected to the first connecting element.
2. The device according to claim 1 , wherein the first plug connecting element movable against the spring force is held at a swivel holder which on at least one swivel arm has a control edge which is inclined relative to the sliding path of the second device part, at which control edge the swivel holder is acted upon by the second device part when the second device part is moved in one of the two sliding directions.
3. The device according to claim 2 , wherein a leaf spring stationarily held at the first device part with its one end acts with its other end on the swivel holder in the direction of the connecting position and forms a control surface which is inclined relative to the sliding path, at which control surface the swivel holder is acted upon by the second device part when the second device part is moved in the other one of the two sliding directions.
4. The device according to claim 2 , further comprising a plug-in device to be received in a device frame, the plug-in device having a hollow-like recess on one of its longitudinal side walls, in which recess the second plug connecting element is stationarily arranged.
5. The device according to claim 4 , wherein the swivel holder has two swivel arms arranged at a distance to each other which corresponds to the width of the recess transverse to the sliding direction, which swivel arms are guided on the device frame with oblong holes and carry the first plug connecting element between their free ends extending in the plug-in direction.
6. The device according to claim 5 , wherein the free ends of the swivel arms are connected to each other via an articulated piece which holds them rotatably on bearing journals.
7. The device according to claim 6 , wherein a two-armed leaf spring, the arms of which are connected to the articulated piece and act upon the latter in the direction towards the connecting position.
8. The device according to claim 6 , wherein the articulated piece has a rounded-off sliding surface on its side facing the connecting position.
9. Apparatus comprising:
a removable device that is slidably inserted and removed from a frame;
the frame having a first electrical connecting element, a swivel holder and a spring; the swivel holder being connected at one end to the frame and at an opposite end to the first electrical connecting element, the spring being connected at one end to the frame and at an opposite end to the first electrical connecting element;
the removable device having a recess, a second electrical connecting element being located in the recess;
the swivel holder and spring being configured such that, upon initial insertion of the removable device into the frame, a first end of the removable device contacts the swivel holder causing the spring to deflect to move the first electrical connecting element to an initial insertion position;
the swivel holder and spring being configured such that, upon further insertion of the removable device into the frame, the spring moves the first electrical connecting element into the recess in the removable device; and
wherein still further insertion of the removable device causes the first electrical connecting element to mate with the second electrical connecting element.
10. The apparatus of claim 9 wherein:
said removable device has a wall adjacent the recess;
the wall, the spring and swivel holder being configured such that, upon separation of the removable device from the frame, the wall deflects the spring to move the first electrical connecting element out of the recess in the removable device to permit the removable device to be completely separated from the frame.
