Description

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.

In contrast to the clamping technique, this technique means that the cable is not separated into several individual cables.

A two-wire flat cable is often used for this, over which both the energy and the function and safety signals are transmitted.

For the connection of active |/O devices, distribution terminals are already used in the AS Interface system, which contact the cable using leverage.

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. 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.

However, 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.

This object is solved by an object with the features of claim 1. Accordingly, in the open position of the lever element, 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. For example, 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. In examples, the recording along a longitudinal axis of the lower part, for example, centrally along the

longitudinal axis, run.

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,

have 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 from one

End runs to an opposite end of the housing.

For this purpose, 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.

For example, 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.

For example, the lever element can have a lever arm with which the user can move the lever element from the open to the locked position.

For locking, 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 peg-shaped projection on the lower part, when transferring into the locked position, so that the lever element is simultaneously moved around the pivot point .

In the open position of the lever element, the lower part and the upper part can be plugged into one another in a straight line or linear manner and surround a section of the flat cable.

When moving into the locked position, 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.

Advantageously, in the construction described here, 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.

This advantageously enables a space-saving and tool-free assembly of the contacting element.

The contacting element is particularly suitable for use as a passive distributor in an AS-Interface system.

However, the contacting element can also be used in other applications, particularly in applications where space-saving installation is required.

In one example, the cable receiving recess in the base is disposed along a longitudinal axis through the base.

For example, the recess can run centrally along the longitudinal axis.

In contrast to a right-angled routing of the cable through the housing, a particularly space-saving assembly of the contacting element can be achieved by running along the longitudinal axis.

In one example, the at least one contact pin is arranged in the upper part.

For example, the contact pin or several contact pins can be formed from an electrically conductive material and have a cutting surface in order to penetrate the material of the cable.

A plurality of contact pins can be spaced apart in the upper part in order to electrically contact an electrical conductor in the cable when the upper part is moved into the locked position together with the contact pins.

In an alternative example, the contact pin or several contact pins can also be arranged in the lower part, or a first contact pin can be arranged in the upper part and a second contact pin can be arranged in the lower part.

In one example, at least one connector is arranged on the upper part as the outlet, the at least one connector being electrically connected to the at least one contact pin. For example, the connector can be designed as a circular connector and have contacts that can be plugged together with corresponding contacts of a corresponding connector in order to thereby electrically contact the conductors in the cable.

In an alternative example, an outgoing line, in particular a round cable, is arranged on the upper part, with at least one conductor of the outgoing line being electrically connected to the at least one contact pin.

A plug connector, for example, can be connected to a free end of the outgoing line. Alternatively, the individual conductors in the output power can also be connected to electronics via terminals.

In one example, the lower part has at least one holding segment, in particular a large number of holding segments, in order to fix the cable in the recess.

The holding segments can be arranged at least in certain areas over the cable in order to hold the cable securely in the recess and thus enable simple assembly of the contacting element.

In one example, the contacting element comprises at least one sealing element, which can be arranged at least in regions between the upper part and the cable. For example, the sealing element can have at least one opening for a contact pin, or have multiple openings for multiple contact pins and surround at least one area of the contact pins in order to counteract the ingress of moisture. A sealing element for each contact pin can also be arranged at least in regions between the upper part and the flat cable.

In one example, the lower part has at least one guide track and the lever element has at least one opening for introduction into the guide track in order to move the lower part and the upper part in a straight line towards one another when transferring to the locked position.

The opening can be designed in the form of a slit and the guide track can be arranged as a pin-shaped projection on the lower part.

The opening can be moved along the guideway in accordance with the course of the guideway while the lever member is moved about the fulcrum.

As a result, a uniform and linear power transmission can be made possible in the tightest of spaces for the transfer into the locked position.

In one example, the lower part has a guide track on opposite side surfaces, the lever element is rotatably mounted on the upper part at two opposite pivot points, and the lever element has two opposite openings in order to move the lower part and the upper part in a straight line when moving into the locked position to move towards each other.

For example, the lever element can be arranged on two opposite side surfaces on the upper part transversely to the recess.

For example, an axle can extend through the upper part and the lever element is connected to the end regions of the axle and is rotatable about the axle.

Correspondingly, the two opposite openings can be moved in guideways running in the same direction, which can be arranged on the lower part.

A particularly secure and energy-saving locking of the contacting element can advantageously be made possible by this construction.

In one example, the lever element is arranged and rotatably mounted on at least one side surface of the upper part in the middle in the extension direction of the upper part along the longitudinal axis.

A central arrangement allows the upper part and the lower part to be brought together evenly when transferred to the locked position.

In one example, the lever member is adapted to snap into the locked position.

For example, the latching can be realized through the use of latching elements or a corresponding design of the opening and guide track. Advantageously, the latching signals to the user that the locked position has been reached and the lever element can be held securely in the locked position.

In one example, the cable is a shape-coded flat cable. Advantageously, incorrect insertion of the flat cable into the recess can be prevented by a shape coding, thereby providing protection against polarity reversal.

In one example, the contacting element has a further recess for receiving a further cable and at least one further contact pin which is adapted to at least partially penetrate the further cable received in the further recess in the locked position.

Advantageously, several cables, for example flat cables, can be contacted at the same time with one contacting element. The invention also relates to an actuator-sensor, AS, interface system, having: at least one cable and at least one contacting element, as described herein, as a passive distributor. The idea on which the invention is based will be explained in more detail below with reference to the embodiments shown in the figures. 1 shows an exploded view of a contacting element according to one embodiment; 2A, 2B sectional representations through the contacting element shown in FIG. 1 in an open position; 3A, 3B sectional representations through the contacting element shown in FIG. 1 in a locked position; Fig. 4A -- 4D representations of the contacting element shown in the previous figures during the transition from the open position to the locked position;

The contacting element 1 shown has a lower part 3 with a recess 5 for receiving the cable 7 shown as a flat cable. In further embodiments, the cable can also be designed as a round cable, for example. In the embodiment shown, the recess 5 extends through the lower part 3, centrally in the longitudinal direction, from a first side of the lower part 3 to an opposite, second side of the lower part 3. FIG. 1 also shows that the recess 5 has a cross section at least in regions , which is complementary to the cross-section of the cable used

7. The cable 7 is shown as a shape-coded flat cable with a web-shaped step in the direction of extension, so that the cable 7 can only be introduced into the recess 5 in the position shown. The inserted cable 7 can be held in the recess 5 in the lower part 3 by means of the tongue-shaped retaining segments 21A-21N, in order to enable the contacting element 1 to be assembled easily.

FIG. 1 also shows that the lower part 3 has fastening lugs on a side opposite the recess 5 in order to be able to be mounted on a substrate.

The lever element 11 shown is rotatably mounted on the upper part 9 shown at two opposite pivot points 27A, 27B. The arrangement of the lever element 11 on the upper part 9 between an open and a locked position is shown more clearly in the figures shown below.

The two contact pins 13A, 13B shown are arranged on the upper part 9 in the assembled state of the contacting element 1 in order to be moved together with the upper part 9, and are adapted to at least partially penetrate the cable 7 accommodated in the recess 5 in the locked position. in order to electrically contact at least one conductor 8A, 8B in the cable 7 in each case. For this purpose, the two contact pins 13A, 13B are arranged at a distance from each other in the upper part 9 in order to make electrical contact with an electrical conductor 8A, 8B in the cable 7 when the upper part 9 is moved into the locked position together with the contact pins 13A, 13B. The two contact pins 13A, 13B shown have cutting surfaces tapering to a point at a first end in order to be able to penetrate the insulation of the cable 7 better. In the embodiment shown, the opposite second ends of the contact pins 13A, 13B are connected to contacts of the connector 17 shown as an outlet. The connector 17 is shown as a circular connector and may be matable with a mating connector (not shown) to thereby electrically contact the conductors 8A, 8B in the cable 7. Furthermore, a sealing element 15A, 15B for each contact pin 13A, 13B is arranged at least in regions between the upper part 9 and the cable 7 in the embodiment shown. FIGS. 2A and 2B show sectional views through the contacting element 1 previously shown in FIG. 1 in an assembled state and in an open position.

FIG. 2A shows a sectional view through the contacting element 1 at a 90° angle to the longitudinal direction, ie the direction in which the recess 5 extends, and FIG. 2B shows a sectional view in the longitudinal direction. In the open position, the upper part 9 is positively placed or plugged onto the lower part 3 and together with the lower part 3 forms the housing of the contacting element 1, through which the cable 7 runs from one end to an opposite end of the housing.

The lever element 11 is in the open position and the contact pins 13A, 13B do not yet contact the electrical conductors 8A, 8B in the cable 7. FIGS. 3A and 3B show sectional views through the previously shown contacting element 1 in the assembled state and in a locked position. When moving into the locked position, the upper part 9 and the lower part 3 are moved in a straight line or linearly towards one another until, in the locked position, the contact pins 13A, 13B the electrical conductors 8A, 8B of the cable 7 accommodated in the recess 5 at least partially penetrate or electrically contact the electrical conductors 8A, 8B. As shown in FIGS. 2A, 2B, 3A and 3B, a rotary movement of the lever element 11 results in a rectilinear or linear relative movement of the lower part 3 and the upper part 9 towards one another. Pivoting of the upper part 9 relative to the lower part 3 is thus eliminated by the linear guide. The transfer of the contacting element 1 from the open position to the locked position is shown in the following FIGS. 4A-4D.

FIG. 4A shows the upper part 9 and the lower part 3 separately from one another. In the recess 5 no cable is arranged. In FIG. 4B, the cable 7 is arranged in the recess 5 of the lower part 3 and the lever element 11 is in the open position. The upper part 9 shown can now, as indicated by the arrow shown in FIG. 4B, be plugged onto the lower part 3 in a straight line or linearly, ie perpendicularly from above.

FIG. 4C shows a state of the contacting element 1 between the open position and the locked position. Shown is the guide track 23A on the lower part 3, which is introduced into the opening 25A on the lever element 11. Due to the pin-shaped or hook-shaped design of the guideway 23A shown and the correspondingly designed opening 25A, the lower part 3 and the upper part 9 are moved in a straight line towards one another when transferred into the locked position. The arrow shown in FIG. 4C indicates that the lever element 11 is moved about the pivot point 27A for this purpose. In the embodiment shown, as is shown more clearly in Figure 1, the lower part 3 has a guide track 23A, 23B on opposite side surfaces, the lever element 11 is rotatably mounted on the upper part 9 at two opposite pivot points 27A, 27B, and the lever element 7 has two opposite openings 25A, 25B in order to move the lower part 3 and the upper part 9 in a straight line towards one another when transferring to the locked position. FIG. 4D shows a state of the contacting element 1 in the locked position. In the locked position, the contact pins (not shown) at least partially penetrate the cable 7 accommodated in the recess 5 . A corresponding plug connector (not shown) can be plugged or plugged into the plug connector 17 in order to make electrical contact with the conductors 8A, 8B in the cable 7 as a result. The lever element 11 engages in the locked position as a result of the shown pin or hook-shaped design of the guideway 23A and the correspondingly designed opening 25A. FIG. 5 shows an exploded view of a contacting element 1 according to a further embodiment.

The contacting element 1 shown differs essentially from the contacting element shown above in that instead of a plug connector, an outgoing line 19, which is shown as a round cable, is arranged on the upper part 9, with at least one conductor of the outgoing line 19 each having a contact pin 13A, 13B is electrically connected.

At the free end of the outgoing line 19 shown, a connector is connected. In alternative configurations, the individual conductors in the output power 19 can also be connected to electronics via terminals.

The upper part 9' can now, as indicated by the arrow shown in FIG. 4B, be plugged onto the lower part 3' in a straight line or linearly, ie vertically from above.

FIG. GC shows a state of the contacting element 1' between the open position and the locked position. The guide track 23A' shown, the opening 25A' and the pivot point 27A can be shaped in the same way as on the contacting element 1 in the previously shown figures.

Also, when transferring to the locked position, the lower part 3' and the upper part 9' are moved towards one another in a straight line. The arrow shown in FIG. 6C indicates that the lever element 11° is moved about the pivot point 27A° for this purpose.

In contrast to the embodiment shown above, both cables 7, 7' received in the respective recesses 5, 5' are contacted at the same time when they are moved into the locked position, which is shown in FIG. 6D. The contacting element 1' has two plug connectors 17, 17' for contacting the conductors 8A, 8B, 8A', 8B' in the respective cables 7, 7°.
