Description

The invention relates to a contact insert for a connector part according to the preamble of claim 1.

Such a contact insert comprises a frame part which has a plug-in section for plug-in connection with a further plug connector part, at least one electrical contact element arranged on the plug-in section and a grounding element arranged on the frame part, to which a protective line can be connected.

Such a contact insert can be used, for example, in a plug housing of a connector part and in this way enables plug housing to be equipped with completely different contact inserts and thus to provide individual plug-in faces adapted to a specific use on the connector part. In this case, one or more electrical contact elements are arranged on the plug portion of the frame part, which engage with an associated, further connector part with contact elements of the further connector part electrically contacting in connecting the connector part, so that an electrical connection between the connector parts is made.

About the earthing element can be done in this case generally plugging in the connector parts grounding between the connector parts, so that the connector parts are in the plugged state at the same grounding potential. In this case, for example, the frame part can also be earthed via the grounding element, if this is made of an electrically conductive (metal) material.

At one of the DE 295 20 008 U1 known connector part, a connector insert has a plurality of rows of contact elements. The contact insert can be used in a mounting housing, which is attached to a mounting wall.

From the DE 10 2007 013 536 B3 a grounding element (referred to as PE metal part) is known, which serves for fastening a contact insert, for example in a connector housing and has a so-called PE screw connection for connecting a protective line.

From the DE 10 2010 017 717 A1 is known a contact insert with a frame part and a contact module insertable therein. On the frame part, a connection device for connecting a protective conductor is arranged, which has a connecting arm with a screw connection.

At one of the EP 0 882 318 B1 known contact insert are a variety of contact modules in a designated frame frame part used. Some of the modules can also be used to connect protective cables to the so-called PE contact (PE stands for "protective earth"). These contact modules are designed as screw connections.

Conventionally, it has been primarily intended to form a connection for connecting a protective line as a screw connection. This allows a reliable, mechanically strong connection of the protective line with the contact insert, but may be subject to restrictions in handling. Thus, under certain circumstances, when the contact insert is inserted into an associated housing of a connector part, a screw connection may no longer be easily accessible, which may necessitate securing a protective line into the housing prior to insertion of the contact insert. In addition, attaching a plurality of protective lines requires the attachment of the protective lines to the (a) screw connection and the simultaneous fixing of the protective lines by tightening a screw.

Object of the present invention is to provide a contact insert for a connector part available that allows easy connection of a protective line.

This object is achieved by an article having the features of claim 1.

Accordingly, the contact insert has a contact element arranged on the grounding element, which has a housing with a plug-in opening for inserting the protective line and a spring element arranged on the housing for locking the protective line in the plug-in opening and for contacting the protective line with the grounding element.

Such a grounding element can be detachably arranged with a contacting device arranged thereon on a frame part of a contact insert become. If appropriate, this can make it possible to equip a contact insert with a grounding element and a contacting device arranged thereon, without the design of the frame part having to be adapted for this purpose. Such a grounding element with a contacting device arranged thereon can thus optionally be used on an already existing frame part and optionally also be retrofitted.

The connection of the protective line to the grounding element to the frame part via a spring force connection. For connecting the protective line to the grounding element, the protective line can be inserted in a simple, convenient manner with a (stripped) wire end in the insertion opening of the housing of the contacting device and thereby passes into the region of the spring element which locks the protective line in the housing and contacting the Protective line causes the grounding element. To connect thus (only) an insertion of the protective line is required. The locking and contacting the protective line to the grounding element can advantageously be carried out automatically without further operating steps for setting the protective line to the grounding element are required.

The spring element has, in one embodiment, a clamping leg, which is in case of plugged into the plug-in protective line with the protective line in abutment. About the clamping leg, the locking of the protective line in the housing of the contacting device, wherein for contacting the protective line to the grounding element of the clamping leg is formed, for example, to push the protective line against a contacting portion of the grounding element and thus bring the protective line in electrical contact with the grounding element.

Upon insertion of the protective line into the plug-in opening of the housing, the protective line acts on the clamping leg of the spring element and deflects it preferably resiliently such that the locking of the protective line is effected in the housing under contact with the grounding element. The clamping leg is movably arranged in the housing for this purpose.

In addition to the clamping leg, the spring element, in one embodiment, a holding leg, via which the spring element is held on the housing. The holding leg can for example be bent over to the clamping leg and fixed between housing sections of the housing in such a way that over the holding leg the spring element is attached to the housing. Upon insertion of the protective line into the plug-in opening of the housing, the protective line acts on the clamping leg and moves the clamping leg to the holding leg with elastic deformation of the spring element, so that the protective line is held under prestress in the housing of the contacting device.

The connection of the protective line with the contacting device is preferably detachable. For this purpose, the contacting device, for example, have an unlocking, which can be actuated to release the protective line and, for example, has an arm with which the Entsperrelement acts on actuation of the spring element. The unlocking element can be actuated, for example, by a tool, for example a screwdriver, and pressed into the housing of the contacting device for actuation. As a result, the unlocking acts with his arm on the clamping legs of the spring element and pushes them out of contact with the protective line, so that the locking of the protective line is removed in the housing and the protective line can thus be pulled out of the plug opening.

In one embodiment, the housing of the contacting device can have two (separate) plug-in openings for inserting two protective lines and two spring elements for locking the protective lines in the plug-in openings. The contacting device thus provides two slots for connecting two protective lines, wherein basically also conceivable and possible, even more slots, e.g. three or four slots, to connect more than two protection lines. In this way, multiple protective lines can be connected in a simple, convenient manner with reliable electrical contact with the grounding element and with reliable mechanical support to the contacting device.

Each spring element may in this case be designed as described above and in particular have a clamping leg for locking and contacting the protective line.

The earthing element has, for example, a contact lug for grounding contact with the further connector part. The contact lug may be, for example, along the connecting direction, along which the connector parts are to be connected to each other, to be extended to the frame part, so that the Kontaktierungsfahne when plugged connecting the connector part with the other connector part runs onto an associated contact portion on the other connector part and thereby establishes a connection between the connector parts for common grounding.

The contact insert may be modular. For example, it may be provided that one or more modular contact modules can be attached to the frame part, which may be formed, for example, as a rectangular receiving frame, to provide the frame part modular with contact modules and thus to create an individual contact insert for a connector part. Each contact module can in this case have one or more insertion openings for insertion of electrical lines and can also have one or more contact elements for contacting with an associated further connector part. For example, a plurality of slots (offset from one another transversely to the connecting direction in each case) can be provided on the frame part, into which a plurality of contact modules can be inserted.

If the contact insert is of modular design with modular modules to be attached to the frame part contact modules, the contact elements of the contact insert are preferably part of the contact modules. In this case, the plug-in portion for plug-in connection with the further connector part can be integrally formed on the frame part or also formed by the contact modules. If the plug-in section is formed by the contact modules, the contact modules thus form the mating face of the connector part on which the contact insert is used.

A contact module to be attached to the frame part can be designed such that a line is to be inserted into a plug-in direction in a plug-in opening of the contact module. Preferably, in this case also the protective line along the direction of insertion into the insertion opening of the contacting device is inserted, so that the connection of the protective line to the contacting device of the grounding element in the same direction as the connection of other electrical lines to the insertion openings of the contact module. The connection of the electrical lines to the contact module can also take place via spring connections, so that protective lines as well as other lines (for example, for a data transmission or to provide an electrical supply) in a simple, optionally also automatable manner can be infected to the contact insert.

In one embodiment, the frame part has a frame opening into which the contact module is inserted. The (rectangular in its basic form) frame part encloses the frame opening and thus creates a receiving space with slots into which one or more contact modules can be used to lock in position with the frame part and thus a (modular configurable) mating face to the frame part create. The one or more contact modules can be inserted in the direction of insertion into the frame opening and are locked in the inserted position with the frame part.

The earthing element is preferably arranged outside the frame opening on the frame part, for example on a narrow end face of the (rectangular) frame part. While one or more contact modules are thus inserted into the frame opening enclosed by the frame opening, the grounding element with the contacting device arranged thereon is fastened outside the frame opening on the frame part, in particular in the region of the front side of the frame part.

It is conceivable that the frame part has a (single) grounding element with a contacting device arranged thereon. It is also conceivable and possible, however, for a grounding element to be arranged on both sides of the frame part on opposite end faces of the frame part, in which case both grounding elements or even only one of the grounding elements can have a contacting device.

In one embodiment, the grounding element is positively connected to the frame part. The grounding element is thus attached to the frame part in such a way that there is a positive connection between the frame part and the grounding element and thus the grounding element is held on the frame part.

Such a form-fitting connection can be made, for example, via an engagement section of the grounding element to be inserted into an engagement opening of the frame part and (additionally or alternatively) via a latching section producing a latching connection with the frame part. The engagement portion may be inserted, for example along the direction of insertion into the associated engagement opening of the frame part and provides a positive connection between the Earthing element and the frame part transversely to the direction of insertion ago. By contrast, the latching section can, for example, engage in engagement with an undercut of the frame part when the engagement section is pushed into the associated engagement opening in order to thereby fix the grounding element in a form-fitting manner to the frame part along the plugging direction. About the engaging portion and the locking portion of the grounding element is set in the frame part attached position thus to the frame part.

This results in an arrangement in which the grounding element can be attached in a simple manner for mounting the contact insert to the frame part and is firmly and resiliently held in the attached position on the frame part.

In one embodiment, the housing of the contacting device is positively connected to the grounding element. The housing may for example be made of an electrically insulating plastic material and summarizes the spring element for the realization of the spring force connection. By way of example, the housing can have a form-locking section (for example in the form of a resilient latching tongue), via which the housing is latched in the attached position to the grounding element. The connection between the housing of the contacting device and the grounding element thus takes place in a form-fitting, latching manner, which allows easy attachment of the housing to the grounding element, in addition firm hold in the attached position.

The contact insert can for example be used on a connector part, wherein such a connector part may have a connector housing in which the contact insert is received. Such a connector housing may be connected to an electrical cable having a plurality of lead wires. It is also conceivable and possible, however, to use such a contact insert, for example on a mounting housing on a control cabinet or other electrical equipment.

Fig. 1 shows a schematic view of two connector parts 1, 3, which can be plugged together along a connecting direction E. Each connector part 1, 3 has a connector housing 10, 30, in each of which a contact insert 2, 4 is received with contact elements arranged thereon. Via a cable outlet 11, 31 is in each case a cable 12, 32 connected to the connector housing 10, 30 and electrically connected within the connector housing 10, 30 with the contact elements of the respective associated contact insert 2, 4.

It should be noted at this point that the present invention can be used not only in connector parts with manually operated connector housings, but also, for example, in electrical equipment, such as a cabinet, provided connectors can be used in which a contact insert, for example, on a device wall, For example, a control cabinet wall is set.

An exemplary embodiment of two contact inserts 2, 4 to be connected with one another along the connecting direction E shows Fig. 2 , Each contact insert 2, 4 has a frame part 20, 40 in the form of a rectangular frame, which forms a frame opening 201, 401, in which - in the illustrated embodiment - a contact module 21, 41 is inserted. On the frame part 20, 40, a plug portion 200, 400 is formed, wherein the plug portion 200 of the one, first contact insert 2 forms a socket into which the plug portion 400 of the frame part 40 of the other contact insert 4 can be inserted.

Each contact module 21, 41 has a plurality of plug openings 210, 410 into which electrical lines 24 (see FIG Fig. 3 ) can be inserted for electrical contacting with contact elements 211, 411 in the form of contact pins or contact sockets. In an interconnected state, the contact elements 211 of the one, first contact insert 2 with the associated contact elements 411 of the other, second contact insert 4 are engaged, so that an electrical contact between the contact inserts 2, 4 is effected.

In principle, one or more contact modules can be inserted into the frame opening 201, 401 of each frame part 20, 40, so that individual contact arrangements for forming an individual mating face can be created on the contact inserts 2, 4. In the illustrated embodiment, (exactly) a contact module 21, 41 is inserted into the frame part 20, 40 in an exact fit and connected in a latching manner to the frame part 20, 40. However, it is also possible to arrange several (smaller) contact modules next to one another in the frame part 20, 40.

On both sides of the frame part 20, 40 grounding elements 22, 42 are arranged, on the one hand via fastening elements 220, 420 allow mechanical fixing of the contact insert 2, 4 on the associated connector housing 10, 30 and on the other hand provide a protective contact between the contact inserts 2, 4. Each grounding element 22, 42 is via latching sections 221, 421 on the him associated frame member 20, 40 supported, in this way (when the frame part 20, 40 is made of an electrically conductive material, in particular a metal material) and the frame part 20, 40 may be included in the grounding.

At the respectively associated plug portion 200, 400 Kontaktierungsfahnen 222, 422 (see Fig. 5B in synopsis with Fig. 2 ) of the grounding elements 22, 42, which pile up when plugging in the contact inserts 2, 4 and thereby produce an electrical contact between the grounding elements 22, 42 of the two contact inserts 2, 4.

At the in Fig. 2 illustrated embodiment of conventional contact inserts 2, 4 are provided to the grounding elements 22, 42 contacting devices 23 ', 43' in the form of screw terminals for connecting protective lines.

In contrast, in the in Fig. 3 to 6 illustrated embodiment of a contact insert 2 to a grounding element 22, a contacting device 23 is arranged, which has a housing 230 with two insertion openings 231 for insertion of protective lines 25 (see Fig. 6 ) and allows a connection of the protective lines 25 by plugging contact.

The contacting device 23 has, as shown in the sectional view Fig. 6 can be seen, two spring elements 26 enclosed and held in the housing 230, which are each associated with one of the insertion openings 231. Each spring element 26 has a clamping limb 260 which extends into the region of the plug-in opening 231 assigned to the spring element 26 and serves for locking and contacting a protective line 25 inserted in the plug-in opening 231. To the clamping leg 260, a holding leg 261 is bent, which is enclosed between housing sections 233 of the housing 230, so that via the retaining legs 261, the spring element 26 is fixed in the housing 230.

The clamping leg 260 is movable in the housing 230, with elastic deformation to the holding leg 261. Upon insertion of a protective line 25 pushes a (stripped) wire end 250 of the protective line 25 on the clamping leg 260 and pushes it aside so that the wire end 250 on the clamping leg 260th can slide past and is pressed elastically against a contacting portion 223 of the grounding element 22 via the end of the clamping leg 260. By (after Type of barbs acting) clamping legs 260, the protective line 25 is locked in the insertion opening 231 when the protective line 25 with the wire end 250 (fully) is inserted into the insertion opening 231. The protective line 25 is thus mechanically held by the spring element 26 on the contacting device 23 and is on the other by elastic pressure of the clamping leg 260 in planar contact with the contacting portion 223 of the grounding element 22nd

The connection of the protective line 25 with the contacting device 23 is detachable. For this purpose, each plug-in opening 231 is assigned an unlocking element 27 which is displaceable in an unlocking opening 232 of the housing 230 such that the unlocking element 27 slides with a body 270 in the unlocking opening 232 by pressure on the unlocking element 27 (eg by means of a tool) and with a from the body 270 protruding arm 271 acts on the clamping leg 260 so that it is pressed out of engagement with the wire end 250 of the protective line 25. The protective line 25 can thus be pulled out of the associated plug-in opening 231.

At the in Fig. 3 to 6 illustrated embodiment, a contacting device 23 is disposed only on a grounding element 22 of the contact insert 2 (in Fig. 3 shown on the left). It is also conceivable and possible, of course, in addition to the other grounding element 22 (in Fig. 3 right) to provide such a contacting device 23.

Via the contacting device 23, it is possible to connect a protective line 25 to the assigned grounding element 22 in a simple manner by plugging it into one of the plug-in openings 231. How out Fig. 3 can be seen, the plug-in direction S, in which the protective lines 25 are to be inserted into the insertion openings 231, the insertion direction S, in which the other electrical lines 24 are inserted into the insertion openings 210 of the contact module 21 of the contact insert 2. The connection of the protective lines 25 can thus be carried out in the same way as for the further electrical lines 24, if appropriate also in the case of a contact insert 2, 4 already framed in a receiving housing.

Figs. 5A and 5B show a view of the contact insert 2 in the connected state with the contact insert 4 within the contact insert 4 associated plug housing 30 (the contact insert 2 is shown without connector housing 10). As is apparent from the sectional view of the two contact inserts 2, 4 according to Fig. 5B can be seen, both contact inserts 2, 4 to each a grounding element 22, 42 a Contacting device 23, 43, so that for both contact inserts 2, 4, the connection of protective lines 25 in a plug-in manner under reliable mechanical connection and electrical contact is possible. The contacting device 43 on the contact insert 4 is in this case constructed identically as described above for the contacting device 23 of the contact insert 2.

As well as out Fig. 5B it can be seen, are in the connected state, the contact lugs 222, 422 of the grounding elements 22, 42 contacting each other in Appendix. When plugging in, the contact lugs 222, 422 run towards each other and thus provide an electrical contact for the common grounding of the contact inserts 2, 4.

The grounding element 22, 42 is connected in the illustrated embodiment form-fitting manner with the associated frame part 20, 40 of the contact insert 2, 4, as described below with reference to FIG Fig. 7 to 11 should be explained with reference to a contacting device 23 having grounding element 22 of the contact insert 2.

The grounding element 22 has support section 224 which extend transversely to the plug-in direction S and carry the fastening elements 220 for fastening the contact insert 2 in the housing 10 of an associated connector part 1. In a position of the grounding element 20 connected to the frame part 20, the support sections 224 lie on an end section 205 of the plug-in section 200 of the frame part 20, as is for example apparent Fig. 8 can be seen, and are supported in the insertion direction S on the frame member 20 about it.

The attachment of the grounding element 22 (with the contacting device 23 arranged thereon) takes place in the plug-in direction S, by engaging a wall section 226 bent engaging portions 225 of the grounding element 22 in the insertion direction S in engagement with associated engagement openings 203 on a front side 202 of the frame member 20 to make in this way a positive connection (transverse to the insertion direction S) between the grounding element 22 and the frame part 20.

If the grounding element 22 is attached to the frame part 20 and the engagement portions 225 have been pushed into engagement with the associated engagement openings 203 until the support portions 224 in contact with the end portion 205th engage the plug portion 200 of the frame member 20, snap the locking portions 221, which protrude against the insertion direction S of the support portions 224, into engagement with undercuts 204 on the end face 202 of the frame member 20, so that the grounding element 22 against the insertion direction S on the end face 202 of Frame part 20 is fixed detent.

In the attached position, the grounding element 22 is thus latchingly connected to the frame part 20 and thereby fixed to the frame part 20.

The contacting device 23 is latching via its housing 230 and thus positively connected to the grounding element 22. The housing 230 has for this purpose on both sides of form-fitting portions 234 in the form of resilient latching tongues, which engage when attaching the housing 230 in the plugging direction S to the grounding element 22 with the Kontaktierungsabschnitten 223 of the grounding element 22, as shown in a synopsis of Fig. 7 and Fig. 11 is apparent. In the fitted position, the form-fit sections 234 engage in latching openings 227 of the contacting sections 223 and thereby secure the housing 230 (with the spring elements 26 enclosed therein) to the grounding element 22.

The contacting device 23 can thus be attached in a simple manner to the grounding element 22 by the housing 230 being plugged into the plug-in direction S to the grounding element 22.

In addition, the grounding element 22 can also be attached to the frame part 20 in a simple manner-with or without a contacting device 23 arranged thereon, resulting in a simple assembly of the contact insert 2.

A grounding element 22 with a contacting device 23 of the type described can be used, in particular, on already existing frame parts 20, without the design of the frame part 20 having to be substantially adapted. Existing frame parts 20 can thus be equipped with grounding elements 22 and arranged thereon contacting devices 23 and optionally also retrofitted.

The idea underlying the invention is not limited to the embodiments described above, but can in principle also be realized in a completely different kind of way.

At a contacting device for contacting with an associated grounding element, one or more insertion openings may be provided for connecting one or more protective lines. For example, Such a contacting device may have only one insertion opening. However, it is also conceivable and possible to provide more than two plug-in openings for connecting more than two protective lines to such a contacting device.

In the illustrated embodiment, exactly one contact module is attached to the associated frame part of a contact insert. It is also conceivable and possible, however, to use several contact modules next to each other to provide different contact elements for creating an individually adapted mating face in the frame part of the contact insert.
