Definitions

  • the invention relates to a connection device according to the preamble of claim 1.
  • connection devices with insulation penetrating contacts are known per se. They are used for fast and safe wiring of flat cables with a relatively large number of conductors.
  • the US 5,704,801 A shows a generic connection device.
  • the construction is basically only suitable for flat cables with very few conductors.
  • the chosen design with brackets on the side of a kind of frame and an eccentric roller leads to a lot of play in the design, which makes it hardly possible to make good contact even with a flat cable with a relatively large number of conductors.
  • connection device From the DE 34 22 607 C1 It is known to design the connection device in such a way that it can only be placed on the flat cable if a conductor or a wire has previously been interrupted at the placement point and has a breakout in this area. Lugs on one of the parts of the connecting device engage in the interrupted area of this wire. This serves to position the connection device and ensures that it can only be installed if corresponding openings are provided. In addition, the approach separates and isolates the two ends of the interrupted conductor. This solution has proven itself, especially when used in cramped building shafts, because it is easy to handle. An analog solution shows that EP 1 518 812 B1 which a connection device of the type DE 34 22 607 C2 for use in lift shafts where, for example, the safety circuit must be interrupted.
  • the EP 1 936 747 A2 discloses a generic connection device.
  • the base housing is constructed in several parts and has a base section and a cover section, which in turn are designed in several parts. It is preferred a sliding cover is provided which is slidably guided on a base plate and which has wedges on its inside which cooperate with wedges of a support plate, the support plate being pressed together with the cable and a receiving plate for the cable as a unit onto the insulation-penetrating contacts.
  • This version is compact and still implements a particularly safe circuit.
  • the object of the invention is to solve this problem.
  • At least one eccentric unit can be arranged on the base housing (or also arranged when making contact) with which the flat cable can be pressed onto the insulation-penetrating contacts until one or more of its conductors have been contacted. Contacting the flat cable is so simple and unproblematic.
  • the eccentric unit has an eccentric housing, in which an eccentric roller is inserted, which is rotatably mounted in the eccentric housing and which is supported in an abutment-like manner against wiring in a connection in or on the base housing, the eccentric housing being rotated relative to when the eccentric roller is rotated Basic housing moves, so that the flat cable can be pressed onto the insulation-penetrating contacts with the eccentric unit until it is contacted.
  • the eccentric unit designed in this way has very compact dimensions and nevertheless enables the conductors of the flat cable to be contacted more easily and reliably with the insulation-penetrating contacts.
  • the contact plate unit is designed as a printed circuit board unit which has at least one printed circuit board which is placed on the base plate, a protective plate having openings, in particular slots, which at least partially covers the protective plate being placed on the printed circuit board in the region of the insulation-penetrating contacts enforce, and from which the insulation penetrating contacts protrude, the protective plate recesses for receiving and supporting base portions of the insulation penetrating contacts when contacting the insulation penetrating contacts, which are conductively connected to the circuit board.
  • two or more eccentric units are also movably guided on a housing offset in the main direction of extension of the flat cable, in particular are displaceable, in order to contact the flat cable in its longitudinal direction at different points. It is advantageous if the housings of these connection devices can be connected to form-locking means (and / or force-locking means), for example to corresponding geometries of one or more dovetail connections.
  • a punching device for severing one or more conductors of the flat cable is attached to the connection device in the main extension device of the flat cable. Since the punching device is not integrated into the housing of the connection device but is designed separately from it, it is possible to provide it specifically only in cases in which a cutting of the conductors e.g. is absolutely necessary to implement a safety circuit. It is particularly advantageous if the connecting device and the punching device have corresponding positive locking means - one or more. Corresponding, interlocking grooves and pins - have, on which they can be aligned in the main direction.
  • connection device and the punching device have corresponding form-locking means on which they can be arranged in the main direction of extension and / or that in and against the skin extension direction on the housings of the connection device and / or the Punching device one or more.
