Definitions

  • the invention relates to a contacting element, in particular for an actuator-sensor, AS, interface system according to the preamble of claim 1 and an actuator-sensor, AS, interface system with a contacting element as a passive distributor.
  • Such a contacting element which can be used as a passive distributor for an actuator sensor, AS, interface system, comprises a lower part having at least one recess for receiving a cable, and an upper part having a lever element rotatably mounted on the upper part between an open and a locked position to lock the top in the locked position on the base. Furthermore, such a contacting element has at least one contact pin, which is adapted to at least partially penetrate the cable accommodated in the recess in the locked position in order to electrically contact at least one conductor in the flat cable.
  • Contacting elements as passive distributors can be used in various systems.
  • a possible use of the passive distributor is in an actuator-sensor, AS, interface system.
  • the AS Interface can also be abbreviated as ASi and referred to in English as Actuator-Sensor Interface, or in German as Aktor-Sensor Interface.
  • the AS Interface is a standard for fieldbus communication that was developed to connect actuators and sensors to replace parallel cabling.
  • the AS interface has been an international standard according to IEC 62026-2 since 1999.
  • the individual actuators and sensors of the AS Interface system can be connected to a continuous cable, for example a flat cable, to connect the individual bus participants.
  • This cable is connected to the individual participants using the so-called penetration technique, which can also be referred to as the piercing technique.
  • penetration technique which can also be referred to as the piercing technique.
  • this technique means that the cable is not separated into several individual cables.
  • a two-wire flat cable is often used for this, via which both the energy and the function and safety signals are transmitted.
  • distribution terminals are already used in the AS Interface system, which use leverage to contact the cable.
  • Such a distribution terminal is described, for example, in the document DE 10 2006 023 351 B3.
  • Other insulation displacement terminals are described in the documents CN 208433536 U, DE 100 57 428 A1, EP 1 704 628 A1 and DE 10 2015 114 134 A1.
  • the passive distributors known from the prior art are implemented using insulation displacement connectors that include a housing with an upper part and a lower part.
  • the cable In the assembled state, the cable is arranged or clamped between the upper part and the lower part, and the necessary contact force for the penetration technique is often applied by means of one or more screws with which the upper part and the lower part are screwed together.
  • the contact pins are arranged in either the upper part or the lower part in order to electrically contact at least one conductor in the flat cable.
  • the interface to the contact pins can be implemented in different ways, for example as a multi-pole M12 outlet, as a cable whose conductors are connected to the contact pins, as a bridge element to a second cable, or as a contact on a printed circuit board.
  • the known passive distributors have the disadvantage that the contact must be made with a tool and defined torques are required for the screw connection described above for certain applications. Due to their design, the well-known distributor terminals for active I/O devices are not suitable for use as passive distributors.
  • the object of the present invention is to provide a contacting element that enables simple assembly without tools in a confined space.
  • the lower part and the upper part are arranged so that they can be plugged into one another in a straight line in a plugging direction, and the lever element is adapted to move the lower part and the upper part straight towards one another when transferred to the locked position.
  • the recess in the lower part can extend or run through the lower part in some areas or completely from one side of the lower part to an opposite side of the lower part.
  • the recess can have a cross section, at least in some areas, which is complementary to the cross section of the cable used, for example the compartment cable used.
  • the recess can also be designed in such a way that when a cable is received, the cable ends essentially flush with an upper side of the lower part, ie does not protrude beyond the upper side.
  • the lower part can also have a holding geometry, for example fastening straps, in order to be able to be mounted on a substrate.
  • the upper part can, when it is placed on the lower part, for example placed in a form-fitting manner, form a housing with the lower part, through which the cable runs from one end to an opposite end of the housing.
  • the upper part and the lower part can have complementary connection structures so that they can be simply plugged together.
  • the at least one contact pin can be arranged in the lower part or the upper part and can be moved with the lower part or the upper part.
  • two contact pins can be arranged in the lower part and/or the upper part in an area below or above the recess and at least partially penetrate the cable accommodated in the recess in the locked position in order to thereby electrically contact at least one conductor in the flat cable. If a cable with additional conductors, that is to say more than two conductors, is used, a correspondingly larger number of contact pins can also be used for making electrical contact with the additional conductors.
  • the lever member is pivoted to the top portion between an open and a locked position to lock the top portion to the base in the locked position.
  • the lever element can be permanently arranged on the upper part, or permanently arranged on the upper part, so that the use of lever or fastening elements to be arranged separately is eliminated.
  • the lever element can have a lever arm with which the user can move the lever element from the open to the locked position.
  • the lever element can have at least one opening, for example a slit-shaped opening, which can be moved on a guide track, which can be arranged as a pin-shaped projection on the lower part, when transferred into the locked position, so that the lever element is simultaneously moved around the pivot point .

  • the upper part and the lower part are moved further in a straight line or linearly towards one another until, in the locked position, the contact pins at least partially penetrate the flat cable accommodated in the recess.
  • a rotary movement on the lever element results in a straight-line or linear relative movement of the lower part and upper part towards one another.
  • a pivoting of the upper part relative to the lower part can thus be omitted due to the linear guide.
  • the contacting element is particularly suitable for use as a passive distributor in an AS-Interface system.

  • the conductor can advantageously be electrically contacted through the insulating material without the conductor having to be freed from the insulating material before connection.
  • the conductor does not have to be re-insulated again.
