A lockable plug connector includes a prong strip housing which contains prong contacts and onto which a multichambered bush housing with bush contacts, connected to electric lines, can be plugged and locked by a snap connection, so that the prong contacts are put into electrical contact with the bush contacts. For the sake of attaining a very compact structure, a cover cap is thrust onto the plug contact side of the bush housing, and with this cap a secondary securing of the bush contacts is achieved. An annular wall of the prong strip housing fits over the cover cap completely and terminates at an end surface in an encompassing recess of the bush housing. For sealing purposes, a sealing plate can be disposed inside the bush housing, a sealing ring can be disposed between the prong strip housing and the bush housing, and a sealing ring encompassing the outer wall of the prong strip housing can be provided.

A two-legged contact spring with a spring base, at least one contact leg and a U-shaped bend is provided as a short-circuit bridge for the connection of two contact elements. The contact leg is freely yielding and has a projection which contactingly rests directly at a transitional region of the contact element. Therefore, the spring work is carried out exclusively by the short-circuit bridge. The spring form and position of the contact point ensures an optimal spring action at low operating forces.

A filter plug includes lateral guides having insertion inclines for positioning and fixing a filter element, preferably a ferrite body, in a chamber of a pin bar body. The filter element is plugged onto plug pins being fixed by lateral spring elements which latch-in on the filter element and press the filter element against the chamber base. This creates a filter element attachment for simple installation which is integrated into the pin bar body, which is secure and insensitive to tolerances and which has no additional attachment devices.

A device cuts vertically fed paper against a cutting edge by means of a carriage driven cutting wheel. There is a chute means downstream from the cutting edge and secured to a pivotable guideway bar, rotated by movement of the carriage during cutting operation. The paper is held against the cutting edge during cutting on one side by the chute means which tilts the paper to be cut toward a deposit tray and on the other side by a pivotable flap biased by a pressure roller mounted on the carriage. In the non-cutting mode, the flap and chute are substantially coextensive to help provide a gap-free pathway for paper being fed into the device.
