Description

The invention relates to an assembly for a connector part according to the preamble of the claim 1 ,

Such an assembly comprises a connector housing and a contact insert which can be connected to the connector housing and which has an insulating body consisting of an electrically insulating material. The insulating body forms a plug-in portion, which is connectable along a plug-in direction with a mating connector part. In addition, one or more electrical contact elements, for example in the form of contact pins or contact bushes, which serve for electrical contact with associated mating contact elements of the mating connector part and plug-in connection of the connector part and the mating connector part are in contact with the mating contact elements on the insulating body.

The use of different, modular insulating in a connector housing a connector part allows the provision of very different connector parts with completely different mating faces and very different kind of contact elements.

While in simple, lightweight connector parts, the connector housing can be made of plastic, it may be advantageous to use metal connector housing, in particular for heavy, particularly stressed in use connector parts. If a plug housing made of metal is used, however, care must be taken to ensure that electrical conductivity on the plug housing does not lead to disadvantages and possible safety risks, for example when an overvoltage occurs.

At one of the DE 20 2006 003 204 U1 known connector part is arranged a contact insert in a connector housing to which a ground contact element (so-called PE contact) is provided.

At one of the DE 10 2010 022 690 A1 known connector part is an insulating body enclosed in a connector housing. On the insulating body, a ground terminal contact element is arranged, which is connectable via a contact plate with the connector housing.

From the DE 10 2012 016 725 A1 a connector part is known with a contact insert having a module frame for receiving contact modules. On the module frame, a ground contact element is arranged.

Object of the present invention is to provide an assembly for a connector part available that allows a simple, inexpensive way to use a metal connector housing.

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

Accordingly, the assembly has a grounding member disposed on the insulator body having a housing contact portion and being electrically connected to a mating portion grounding contact member for mating contact with the mating connector portion, wherein the housing contact portion is configured to electrically contact the connector housing when the contact insert connected to the connector housing.

Thus, when the contact insert is inserted into the connector housing, the connector housing is pulled into the ground. This is done via the grounding element, which on the one hand has a housing contact section for electrically contacting the plug housing and on the other hand is electrically connected to a ground contact element, so that an electrical connection exists between the plug housing and the ground contact element via the grounding element. The grounding contact element, to which a grounding line may be connected, comes in mating connection of the connector part and the mating connector part in grounding contact with the mating connector part, so that there is a same ground potential at the connector part and the mating connector part.

The insulating body is preferably integrally molded, for example, from a plastic material. The insulating body is electrically insulating and in this way isolates the contact elements arranged on it from the plug housing, which is preferably formed from an electrically conductive metal material.

By using the grounding element can be done in a simple manner grounding contact with the connector housing. For example, the contact can be made automatically when inserting the contact insert into the connector housing, so that no additional assembly steps for the preparation of grounding contact are required.

In one embodiment, the earthing contact element extends along the plug-in direction and, when plug-in connecting the plug connector part and the mating plug connector part, contacts one another along the plug-in direction an associated mating contact element of the mating connector part. When plugging in the connector part and the mating connector part, the earthing contact element thus runs on an associated mating contact and establishes an earthed contact via it.

In one embodiment, the housing contact section extends over a plane extending transversely to the plug-in direction. The housing contact portion thus provides a contact surface available, which rests flat when the contact insert inserted on the connector housing and produces an electrical contact of the grounding element with the connector housing.

At least one attachment point for mechanical attachment of the contact insert to the connector housing can be arranged on the housing contact section according to a further embodiment. The housing contact portion is used in this case not only for electrical contacting of the grounding element with the connector housing, but also for mechanical attachment of the contact insert with the connector housing.

The housing contact portion may be formed, for example, as a flange and protrude from the insulating body. Thus, on the one hand, the electrical contacting of the grounding element with the plug housing and, on the other hand, the mechanical attachment of the contact insert in the plug housing can take place via the housing contact section.

The housing contact portion may, in another embodiment, be arranged in the region of a transversely extending to the insertion direction, can be brought into planar contact with the connector housing attachment portion of the insulating body. The fastening portion of the insulating body may be formed, for example, as a shoulder on the insulating body and may rest against the plug housing when inserted into the plug housing contact insert, so that a mechanical attachment of the contact insert in the plug housing can be made via the attachment portion. Characterized in that the housing contact portion is arranged in the region of the fastening portion, it is ensured that when inserted into the connector housing contact insert, an electrical contact between the housing contact portion of the grounding element and the connector housing.

Completely different variants of the grounding element and of the grounding contact element connected to the grounding element are conceivable and possible.

In a first variant, the contact element, for example, take over the additional function of a coding. Under a coding is a form of the male portion of the connector part to understand, which ensures that the connector part can be connected only in a predetermined position and orientation plugged with the mating connector part. Such a coding can be made for example by longitudinally along the plug-in direction extended webs, which are arranged unevenly distributed on the plug-in portion and force it over a positionally correct and orientation correct attachment of the connector part to an associated mating connector part.

If the earthing contact element assumes an additional function for the coding, then - in the case of what is known as a male connector part - the grounding contact element may extend on an outer side of the plug-in section and protrude transversely to the plugging direction to provide the coding of the plugging section. In this case, the ground contact element preferably extends along the plug-in direction on the plug-in section, so that the ground contact element forms a protruding web on the outside of the plug-in section which, when plugged in, is to be engaged with an associated counter-coding on the side of the mating plug connector part.

Alternatively, in the case of a so-called female connector part, the earthing contact element may also be arranged on an inner side of the plug-in section in the region of a coding element. Again, the ground contact element is part of the coding and may for example extend between radially inwardly projecting webs on the plug portion.

In this variant, the grounding contact element is, for example, integrally formed on the grounding contact element, so that the grounding contact element extends, for example, in the shape of a pencil from the grounding element along the plug-in section.

In another, second variant, the grounding contact element can also be enclosed by the plug-in section, but not be part of a mechanical coding. In this case, the grounding contact element is arranged, for example, as a separate element to the grounding element within the plug-in section and, for example, held mechanically at the plug-in section, for example latched to the plug-in section. The grounding contact element may be formed in this case, for example, as a contact pin or as a contact socket and, when plugged connecting the connector part and the mating connector part together, in electrically contacting Connection with an associated mating contact element of the mating connector part.

In this case, the earthing element is used for the electrical connection of the earthing contact element arranged inside the plug-in section and the plug housing surrounding the insulating body. The grounding element may, for example, have a contact portion for electrical connection to the ground contact element, which is connected to the housing contact portion via a connection portion. The contact portion is in electrical connection with the ground contact element and may, for example, have an opening through which the ground contact element engages. The connecting portion has, for example, the shape of a current bar, which produces an electrically conductive connection between the contact portion and the housing contact portion of the grounding element.

In one embodiment, in this case the contact portion relative to the connecting portion and / or the connecting portion relative to the housing contact portion may be angled. While, for example, the contact section and the housing contact section extend flat along a plane extending transversely to the plug-in direction, the connection section can, for example, extend along a plane which is spanned by the plug-in direction and a transverse direction directed transversely to the plug-in direction.

The grounding element can be made in a very different way.

Thus, in one embodiment, the grounding element can be attached as Ansetzteil to the insulator of the contact insert. In the attached position, the grounding element is for example held in a form-fitting manner on the insulating body.

In another embodiment, the grounding element may be encapsulated by the (plastic) material of the insulating body, in which case the housing contact portion for contacting with the plug housing and also the contact portion for contacting with the ground contact element exposed so that an electrical contact can be made. The grounding element is thus inserted in the manufacture of the insulating body in an injection mold and encapsulated by injection molding of material.

In yet another embodiment, the grounding element can also be manufactured as a metal injection molded part on the insulating body. Such a metal injection molded part can be manufactured directly on the insulating body by injecting a metal alloy into a recess on the insulating body. For this purpose, for example, a eutectic alloy with a low melting temperature can be used. Alternatively, such a metal injection molded part can be prefabricated and then encapsulated or encapsulated with (plastic) material to form the insulating body.

As another manufacturing method which may be used to fabricate the grounding member, there is also considered a metal powder injection molding (MIM) method in which a fine metal powder is mixed with an organic binder and molded. By subsequent sintering, the grounding element is compressed, so that a solid metal component of high density is obtained, which can then be overmoulded with the material of the insulating body.

In yet another embodiment, the grounding element can be arranged on a cover element connected to the insulating body. The cover may for example be attached to one end of the insulating body, which faces away from the plug portion, and may for example be positively connected to the insulating body, for example via fastening tabs which are latchingly connected to the insulating body. About the cover, for example, contact elements can be held on the insulating body and supported relative to the insulating body.

The grounding element can in this case be held in a form-fitting manner between the cover element and the insulating body. For this purpose, the grounding element can for example be accommodated on the cover element in such a way that, when the cover element is attached to the insulating element, the grounding element comes to rest between the cover element and the insulating body and is thus held in a positionally fixed manner relative to the insulating body.

Alternatively, the grounding element may, for example, be encapsulated by the material of the covering element. The cover is made in this case by injection molding (plastic), wherein in the injection molding, the grounding element is inserted into an injection mold and encapsulated by the material of the cover.

The grounding element may, for example, protrude transversely to the direction of insertion to the cover element, so that the housing contact section of the grounding element protrudes laterally and can come into contact with an inner wall of the plug housing when the contact insert is inserted into the connector housing.

In a specific embodiment, the grounding element, for example, a transversely to Plug-in direction extending connecting portion, on which the housing contact portion and arranged on the connecting portion contact lug are arranged for electrical connection to the ground contact element. The connecting portion realizes in this case a current bar for the electrical connection of the housing contact portion and the contact lug. The contact lug is supporting in contact with an associated grounding contact element, so that via the contact lug an electrical contact with the grounding contact element is made.

In an advantageous embodiment of the housing contact portion is elastically resilient transversely to the insertion direction. This can in particular enable a sliding of the housing contact portion on an inner wall of the plug housing during insertion of the contact insert into the plug housing, with electrical contacting of the housing contact portion with the plug housing.

The assembly is preferably part of a connector part, in particular a heavy connector part for use in stressed environments. By selecting from very different contact inserts, a connector part can be created in a modular manner, which is adapted in a dedicated way to a particular use and has a suitable mating face with an array of contact elements.

Via a cable outlet 11 . 31 is each a cable 12 . 32 to the connector housing 10 . 30 connected and inside the connector housing 10 . 30 with the contact elements of the respective associated contact insert 2 . 4 electrically connected.

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.

1 and 2 show a first embodiment of a contact insert 2 , which is to form a connector part 1 in a connector housing 10 (please refer 14 ) is to be used.

The contact insert 2 has an insulating body 20 on, which is made of an electrically insulating (plastic) material. The insulator 20 forms a plug-in section 206 from, for connecting two mutually associated connector parts 1 . 3 with a plug-in section 406 a complementary, in 3 and 4 illustrated contact insert 4 can be connected and in the plugging direction e in a plug-in opening 400 of plug section 406 of the contact insert 4 can be inserted.

At the plug-in section 206 are plug-in openings 200 formed in which contact elements 22 are arranged, which are designed as contact pins and for electrical contact with contact elements 42 in the form of contact sockets within the plug opening 400 of the plug-in section 406 of the contact insert 4 serve.

At a lower section 203 of the insulating body 20 is a cover element 21 arranged the lower section 203 with a wrap-around section 210 encompasses and over fastening straps 211 - By engagement of locking elements 204 at the bottom section 203 in openings 212 in the fastening straps 211 - Form-fitting on the lower section 23 is fixed (in 1 is just a fastening tab 211 visible, noticeable; opposite, the cover element 21 another fastening strap 211 on).

Transverse to the mating section 206 stands on one side a mounting portion 202 for attaching the contact insert 2 within the associated connector housing 10 in front. Opposite is on the insulator 20 a grounding element 23 arranged in a separate representation in 2 is shown and at one of the plug portion 206 above landing stage 205 opposite the insulating body 20 is supported.

The earthing element 23 has housing contact sections 231 on, as the flange sections transversely from the plug section 206 protrude (if the grounding element 23 to the insulator 20 is set) and mounting holes 232 carry over the attachment of the contact insert 2 with the associated connector housing 10 can be produced.

To the housing contact sections 231 closes a surface section 233 in which a mounting hole 235 for fixing the grounding element 23 on the insulating body 20 by means of a fastener designed as a screw 236 is arranged and from that point to the insulator 20 Form-fitting elements 234 for engagement in the insulating body 20 and oppositely directed protrusion elements 238 protrude.
