SUMMARY OF THE INVENTION It is an object of the present invention to provide an assembly for connector members which allows the use of metal connector housings in an easy and advantageous manner.

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

According to it, the assembly has a grounding element arranged on the insulator, the grounding element having a housing contact portion, a grounding contact element arranged on the plug-in portion and a mating connector member. and the housing contact portion is configured to make electrical contact with the connector housing when the contact insert is connected to the connector housing.

According to it, when the contact insert is fitted in the connector housing, the connector housing is brought to ground. This is done through a grounding element which on the one hand has a housing contact part for electrical contact of the connector housing and on the other hand is electrically connected to the grounding contact element, so that through the grounding element the connector housing and the An electrical connection exists between the ground contact element. The ground contact element to which the ground wire can be connected is brought into ground contact with the mating connector member upon a plug-in connection between the connector member and the mating connector member, whereby the connector member and the mating connector member The same ground potential exists.

The insulator is preferably integrally molded, for example from a plastic material. The insulator has an electrically insulating action and in this way insulates the contact elements arranged in the insulator from the connector housing, which is preferably constructed of an electrically conductive material.

Through the use of the grounding element, ground contact can be made with the connector housing in an easy manner. For example, no additional mounting step is required to form the ground contact, as the contact can be formed automatically when the contact insert is fitted into the connector housing.

In one embodiment, the grounding contact element extends along the plug-in direction and, when the connector member and the mating connector member are plugged into each other, ground along the plug-in direction while grounding the mating connector member. It contacts the arranged mating contact element. Accordingly, upon plug-in connection of the connector member and the mating connector member, the ground contact element is superimposed on the provided mating contact and thereby forms a ground contact.

In one embodiment, the housing contact portion extends planarly along a plane extending transversely to the insertion direction. Thus, the housing contact portion provides a contact surface which, when the contact insert is fitted, rests flush against the connector housing and also forms electrical contact between the ground element and the connector housing.

According to another embodiment, the housing contact portion may be arranged with at least one fixing position for mechanically fixing the contact insert to the connector housing. In this case, the housing contact portion serves not only for the electrical contact between the grounding element and the connector housing, but also for the mechanical fixation of the contact insert with the connector housing.

The housing contact portion may be configured, for example, as a flange and protrude from the insulator. Through the housing contact portion, on the one hand, the electrical contact between the grounding element and the connector housing can therefore take place, and on the other hand, the mechanical fixation of the contact insert in the connector housing can take place.

In another embodiment, the housing contact portion may be arranged in the region of a fixed portion of the insulator extending transversely to the plugging direction and operatively connectable with the connector housing in a supporting manner. A fixed portion of the insulator can be molded onto the insulator, for example as a ledge (e.g. in the form of a step), and when the contact insert is fitted into the connector housing it can be supported on the connector housing so that through the fixed portion the connector A mechanical fixation of the contact insert within the housing can be provided. The arrangement of the housing contact portion in the region of the fixed portion ensures that electrical contact exists between the housing contact portion of the grounding element and the connector housing when the contact insert is fitted into the connector housing. It is In this case, the housing contact part can be configured, for example, as a flange and attached to the fixed part of the insulator. However, it is also conceivable for the housing contact part to be fitted into a fixed part of the insulator, for example.

A great variety of variations of the grounding element and the grounding contact element connected to the grounding element are conceivable and may exist.

In a first variant, the contact element may assume an additional function, for example coding. A coding is understood to be a mold part of the plug-in part of the connector member which ensures that the connector member can only be plugged in a predetermined position and orientation and connected with the mating connector member. Such a coding can be formed, for example, by webs extending along the plug-in direction, which webs are arranged unevenly distributed over the plug-in section, so that the connector member is arranged to force the correct positional and directional attachment to the mating connector member.

If the ground contact element takes on the additional function of coding, in a so-called male connector member the ground contact element extends, for example, on the outer side of the plug-in part and, for the coding, transversely to the plug-in direction. Additionally, it may protrude from the insert. The ground contact elements then preferably extend along the plug-in direction over the plug-in portion, whereby the ground contact elements form a projecting web on the outside of the plug-in portion, which web is , can be brought into engagement with a surface of the mating connector member upon plug-in connection with the mating coding provided.

Alternatively, in a so-called female connector member, the ground contact element can also be arranged on the inner face of the plug-in part in the region of the coding element. Again, the ground contact element may be a component of the coding, e.g. extending between the webs on the radially inwardly projecting spigot portion.

In this variant, the ground contact element is for example integrally molded on the ground contact element, whereby the ground contact element extends from the ground element, for example along the spigot, like a pin. there is

In another variant, the ground contact element is surrounded by a plug-in portion. In this case, the grounding contact element is arranged in the plug-in part, for example as a separate element from the grounding element, for example mechanically held on the plug-in part, for example fixed on the plug-in part. In this case, the grounding contact elements can be configured, for example, as contact pins or contact sockets, and when the connector member and the mating connector member are plugged into each other, the mating contacts arranged on the mating connector member. Leads to connections with elements and electrical contacts.

In this case, the grounding element is used for electrical connection between the grounding contact element arranged inside the plug-in part and the connector housing enclosing the insulator. The ground element can, for example, have a contact portion for electrical connection with the ground contact element, said contact portion being connected to the housing contact portion via the connection portion. The contact portion is electrically connected to the ground contact element and may, for example, have an opening through which the ground contact element extends. The connection part has, for example, the shape of a current bar and forms an electrically conductive connection between the contact part and the housing contact part of the grounding element.

In one embodiment, the contact portion may then be bent with respect to the connection portion and/or the connection portion with respect to the housing contact portion. For example, the housing contact portion extends planarly along a plane extending transversely to the plug-in direction, while the connecting portion extends, for example, in the plug-in direction and transversely oriented transversely to the plug-in direction. It may extend along a plane formed by the direction. The connecting portion may be folded and/or bent multiple times.

For example, the connecting portion extends between the housing contact portion and the contact portion, enclosing a body portion of the insulator, for example a body portion in which the contact element or elements of the contact insert are held. It is possible to The housing contact portion may extend transversely to the insertion direction, for example like a flange. The connection part may form the connection between the housing contact part and the contact part and thereby the connection with the ground contact element, for example like a current bar.

In one embodiment, the contact portion connecting the grounding element with the grounding contact element is configured to be resilient and contacts the grounding contact element in electrical contact. The contact portion is thus configured like an elastic switch and is used to make electrical contact between the ground contact element and the ground element.

The grounding element has, for example, two, for example facing, contact portions which receive the grounding contact element between themselves and thus form an electrical contact with the grounding contact element.

In another embodiment, two grounding elements are provided, each having a housing contact portion and a contact portion connected to the housing contact portion through a connecting portion, e.g. are placed on opposite sides of the In so doing, the contact portions of the grounding element receive the grounding contact element therebetween, and in this way, by forming electrical contact with the grounding contact element and both grounding elements, the grounding element: contact the ground contact elements together.

Each grounding element may be arranged, at its housing contact portion, on a fixed portion of the insulator and supported on an arranged fixed portion.

In one embodiment, the grounding element is attached to the insulator of the contact insert as an attachment member. In the mounted position, the grounding element is, for example, form-lockingly held in the insulator.

In another embodiment, the ground element may be insert molded from an insulating (plastic) material, in which case the housing contact portion is exposed for contact with the connector housing and the contact portion is also , are exposed for contact with a ground contact element, whereby an electrical connection can be made. Therefore, the grounding element is fitted into an injection mold during the manufacture of the insulator, insert molding the material by injection molding.

In yet another embodiment, the ground element may be molded onto the insulator as a metal injection molded part. Such metal injection molded parts can be manufactured directly on the insulator by injecting the metal alloy into recesses in the insulator. For this purpose, for example, eutectic alloys with a low melting point can be used. Alternatively, it is also possible to form a precast of such a metal injection molded part and then insert mold or recast with (plastic) material to form the insulator.

Another manufacturing method that can possibly be used to manufacture the grounding element is the metal powder injection molding method (from English Metal Injection Molding to MIM), in which a fine metal powder is mixed with an organic binder and molded. be done. Subsequent sintering compresses the ground element, thereby yielding a dense solid metal member which can then be insert molded with an insulating material.

Again in another embodiment, the ground element may be arranged on the cover element connected to the insulator. The cover element may, for example, be attached to the end of the insulation facing away from the plug-in portion and is, for example, form-fittingly connected to the insulation, for example through a fixing plate which is connected to the insulation in a fixed manner. It's okay. By means of the cover element, for example, the contact element can be held on and supported against the insulator.

In this case, the ground element can be held form-locking between the cover element and the insulator. For this purpose, the grounding element may for example be received on the cover element, so that when the cover element is mounted on the insulator, the grounding element is located between the cover element and the insulator. and thus held in a fixed position relative to the insulator.

Alternatively, the grounding element may be insert molded, for example, from the material of the cover element. In this case, the cover element is molded by injection molding (from plastic), during which the grounding element is fitted into the injection mold and is insert molded with the material of the cover element.

The grounding element can project into the cover element, for example transversely to the plug-in direction, whereby the housing contact portion of the grounding element projects laterally and, when fitting the contact insert into the connector housing, It can contact the inner wall of the connector housing while making electrical contact.

In a specific embodiment, the grounding element has a connection part extending, for example, transversely to the insertion direction, the connection part comprising a housing contact part and a ground contact part arranged on the connection part. A contact tab is arranged for electrical connection with the contact element. In this case, the connecting part realizes a current bar for the electrical connection of the housing contact part and the contact tab. The contact tabs are in supportive contact with the disposed ground contact elements so that there is electrical contact with the ground contact elements through the contact tabs.

In an advantageous embodiment, the housing contact portion is elastic in the direction of insertion. This particularly allows the housing contact portion to slide over the inner wall of the connector housing while the housing contact portion is in electrical contact with the connector housing when the contact insert is fitted into the connector housing.

The assembly is preferably a component of a connector member, particularly a heavy connector member component for use in high load environments. By choosing from a wide variety of contact inserts, a modular connector member can then be formed, which is adapted in a specialized way to a particular use, so that the contact elements have suitable mating surfaces with the assembly of

Each connector member 1, 3 has a connector housing 10, 30 in which a contact insert 2, 4 respectively is received with a contact element arranged thereon. Via the cable outlets 11, 31, the cables 12, 32 are connected to the connector housings 10, 30, respectively, and are electrically connected to the contact elements of the contact inserts 2, 4 respectively arranged inside the connector housings 10, 30. It is connected.

It should be noted at this point that the invention can be used not only in connector members having connector housings that can be handled by hand, but also in connector members provided in electrical installations such as switchboards, for example. It is possible and in such electrical installations the contact insert may be fixed to the wall of the appliance, for example the wall of a switchboard.

FIGS. 1 and 2 show a first embodiment of a contact insert 2 which is to be fitted into a connector housing 10 (see FIG. 14) to form connector member 1. FIG. be.

The contact insert 2 has an insulator 20 made from an electrically insulating (plastic) material. The insulator 20 constitutes a spigot portion 206, which is complementary, shown in FIGS. 3 and 4, for connecting two mutually arranged connector members 1, 3. It is connectable to the plug-in portion 406 of the contact insert 4 and can therefore be plugged in the plug-in direction E into the plug-in opening 400 of the plug-in portion 406 of the contact insert 4 .

A plug-in opening 200 is formed in the plug-in part 206 , in which a contact element 22 is arranged, which is constructed as a contact pin, and which the contact insert 4 has. The plug-in part 406 is used for electrical contact with the contact element 42 having the shape of a contact socket inside the plug-in opening 400 .

A cover element 21 is arranged on the lower part 203 of the insulator 20 , the cover element 21 surrounding the lower part 203 with a surrounding part 210 and fixing the lower part 203 through a fixing plate 211 . It is form-lockingly fixed to the lower part 23 by engagement of the element 204 in the opening 212 in the fixing plate 211 (in FIG. 1 only the fixing plate 211 is visible; on the opposite side the cover element 21 is , with a further fixing plate 211).

Transversely to the plug-in part 206, on the side, the fixing part 202 projects for fixing the contact insert 2 inside the connector housing 10 arranged. On the opposite side, the insulator 20 is arranged with a grounding element 23 which is shown separately in FIG. Supported.

The grounding element 23 has a housing contact portion 231 which projects laterally from the insert portion 206 as a flange portion (when the grounding element 23 is attached to the insulator 20) and a fixing opening. It has a portion 232 through which a fixation with the connector housing 10 in which the contact insert 2 is arranged can be formed.

Connected to the housing contact portion 231 is a planar portion 233 in which a fixing opening 235 secures the grounding element 23 to the insulator 20 by means of a fixing element 236 configured as a screw. A form-fitting element 234 protrudes from the planar portion 233 towards the insulator 20 for engaging the insulator 20 and a projecting element 238 protrudes in the opposite direction. The form-fitting element 234 secures the grounding element 23 to the insulator 20 in the correct position. On the other hand, the form-fitting element 238 is used to prevent the washer 239 (see FIG. 1) from rotating together when the fixing element 236 configured as a screw is rotated.

Through a contact portion 237 connected to the planar portion 233, the ground wire can be connected to the ground element 23, for example by crimping.

Firstly, the ground contact element 230 is used during a plug-in connection between the connector member 1 arranged on the contact insert 2 and the connector member 3 arranged on the contact insert 4 (see FIGS. 3 and 4). Second, it is used to make electrical contact with the ground contact element 430 of the ground element 43 of the contact insert 4 . A ground is thus formed between the contact inserts 2 and 4 through the ground contact element 230 . Secondly, the ground contact element 230 is used to provide the coding for the contact insert 2 in cooperation with the coding element 201 (configured on the side of the plug-in portion 206 facing away from the ground element 23). , the coding permits connection of the contact insert 2 with the provided contact insert 4 in only one position and orientation. The coding has different widths for the coding elements 201 and the ground contact elements 230, so that the insertion of the insertion portion 206 into the insertion opening 400 is the insertion formed by the web on which the coding element 201 is arranged. It is only possible to press into the coding element 407 of the part 406 and to press the ground contact element 230 into the opposite coding element 401 in whose area the ground contact element 430 of the ground element 43 of the contact insert 4 is arranged. is brought about by being

The direct fixing of the housing contact portion 231 to the connector housing 10 via the fixing opening 232 then ensures a planar contact with the connector housing 10, thereby ensuring electrical contact.

The ground contact with the complementary contact insert 4 is made through a ground element 230 which, upon plug-in connection of the connector parts 1 , 3 , overlies the ground contact element 430 on the plug-in portion of the contact insert 4 . 406 slides inside bayonet opening 400 and thereby makes electrical contact.

Through a contact portion 437 connected to the planar portion 433, the ground wire can be connected to the ground element 43, for example using crimping, or alternatively the ground wire is screwed through the fixing element 436 to the ground element 43 may be connected.

A grounding contact element 430 integrally formed on the grounding element 43 is located inside the insertion opening 400 in the region of the coding element 401 , ie in the insertion direction E, when the grounding element 43 is arranged against the insulator 40 . between the webs of coding elements 401 extending longitudinally along and are therefore constituents of the coding elements 401 . Upon plug-in connection of the contact inserts 4 and 2, the ground contact element 230 of the contact insert 2 slides over the ground contact element 430 of the contact insert 4, thereby providing a contact between the contact inserts 2 and 4. , forms the ground electrical connection.
