Description

The invention relates to a bushing adapter with at least one connector, which comprises a socket part and a plug part, and with an outer side and an inside base plate that has a recess for the connector. The invention further relates to a connector for the bushing adapter with a socket part and a plug part.

Such a bushing adapter is known from DE 198 26 453 A1. The Feedthrough adapter is usually used in a control cabinet a component installed in the control cabinet to an external electrical line to join. The bushing adapter thus serves as an interface between the outside world and the inside of the control cabinet and points to this in usually several connectors. The use of a connector enables easy and safe connection of both the external Management as well as the internal component. Both the line and the component are in particular multi-pole system connectors with predefined Assignment of the individual poles or contacts, connected to the connector. On the one hand, they are on the socket part, which has contact sockets, and on the other hand connected to the plug part, which has contact pins.

DE 198 26 453 A1 deals in particular with the special design of the bushing adapter with regard to sealing against moisture and / or foreign bodies, as required by the IEC 529 standard for the degree of protection IP54 defined therein.
Due to safety-related aspects, the bushing adapter must be designed in such a way that contact with a live contact part is impossible. For the connector with the connector part, this means that its contact pins must not be live as long as they are accessible. Unlike the socket part, the plug part must therefore not be provided as a current or data output but only as an input.

The control cabinet is usually supplied with both live cables also dissipated, i.e. in some cases, the control cabinet directs the supply to it Forward electricity to other components, such as machines or subordinate control cabinets. The one for the corresponding Enclosure adapter provided for the control cabinet must therefore be connected to the plug suitable to ensure that the current output realized from the control cabinet by a socket part of a connector is. The special purpose of the respective control cabinet and in particular its internal wiring as well as its external connections must therefore already taken into account in the design and manufacture of the bushing adapter become. Since this differs depending on the type of control cabinet, one is comparative high expenditure in the production of the lead-through adapter necessary, and short-term changes in the implementation adapter, in particular on site during assembly on the control cabinet are only possible with great effort.

The invention has for its object to provide an inexpensive and flexible To enable bushing adapters.

The object is achieved according to the invention by an electrical bushing adapter with at least one connector that is a socket part and a Includes plug part, and with an outside and an inside Base plate that has a recess for the connector, the Connector in the recess is optionally attachable such that either the socket part or the plug part is accessible from the outside of the base plate is.

The optional two-sided fastening of the plug part in the recess has the decisive advantage that regardless of the special requirement, whether a current output or a current input is provided in a control cabinet the same connector can be used. Than ever either the socket part or the plug part is exposed to the outside upon request arranged in order to meet the safety requirements Afford. This allows special, cabinet-specific requirements for the Bushing adapters can be considered quickly and flexibly. In addition, the necessary variety of parts reduced, so that the bushing adapter inexpensive can be manufactured.

According to a particularly useful embodiment, the connector is in the recess can be locked by means of a locking connection. The rest connection is thereby of a locking bar and a locking recess into which the locking bar engages, educated. The latching web is preferably on the base plate and the latching recess molded onto the connector. The reverse order, so the arrangement of the locking bar on the connector and that of the locking recess on the base plate, is equally possible.

The connector can be locked in place to make it quick and easy Fastening in the recess of the base plate. In connection with the possibility the double-sided arrangement of the connector has this significant Advantage that the special design of the bushing adapter is immediately in front Location directly on the control cabinet is made possible without spending a lot of time. Thereby So individual requirements can be realized quickly and easily, without causing additional costs.

To ensure that the connector is securely fastened in the recess, the snap connection locks the connector in and at the same time against its direction of insertion. These two directions are the same Plug-in directions for plugs for connecting external lines from the outside or for connecting a component arranged in the control cabinet from the inside. This ensures that the connector can also be inserted the connector is firmly in place. For this purpose, the recess and the Locking bridge - seen in section through the locking connection - preferably rectangular educated.

In an expedient embodiment, the connector has in the middle of it Longitudinal expansion of the locking recess or the locking web. The The socket part and the plug part are therefore symmetrical to the snap connection arranged so that the connector is always the same in relation to the base plate is aligned, regardless of whether the socket part or the plug part faces outwards. Due to the central arrangement is to ensure this symmetrical alignment a single snap connection is also sufficient. Alternative to the only one Snap connection can also have several snap connections along the connector be provided, for example one on the socket part and one on Plug part.

Preferably extends from the inside and approximately vertically to the base plate a retaining web, which is a lateral boundary of the recess forms and has the locking web or the locking recess at the end. The landing stage is preferably flexible. When inserting the connector in the recess, the retaining web dodges, and when the end position is reached of the connector, the snap bar snaps into the corresponding snap recess of the connector. The footbridge thus leads the Steckver binder in a certain way and ensures a secure hold in the recess.

According to a preferred embodiment, the connector has two housing halves on, each comprising either the socket part or the plug part. The two-part design enables simple manufacture of the connector, because on the one hand two comparatively geometrically simple housing parts can be produced, in particular injection molded, and since on the other hand quick and easy assembly is possible.

For easy assembly, the two housing halves are preferably one inside the other pluggable, the locking recess or the stop bar is formed. The two housing halves are preferably fixed together connected, for example by a snap connection.

Tapered for the formation of an easy to produce locking recess In an advantageous embodiment, the first half of the housing on the second Half housing oriented connection end forming a step, wherein the side flank of the step forms a wall of the recess, and the step base as a contact surface for the connecting end of the second housing half serves.

To complete the locking recess, the connection end preferably has the second half of the housing on a dock, which in the assembled state abuts the contact surface of the first housing half and a bottom of the locking recess forms. A locking hook connects to the jetty, which is another Wall of the recess forms, and the inclined towards the recess increases. This slope ensures that when the connector is inserted the locking web formed on the retaining web of the base plate is pushed away until the Resting recess and the locking web lie one above the other and the locking web in the Snap recess snaps into place. In this special two-part version of the Connector is the recess through the interaction of formed two housing halves.

According to a further preferred embodiment, the bushing adapter is at least partially designed as a distributor connector. For this purpose, contacts are ver different connectors connected together. This connection takes place in particular over a bridge, which is internal, i.e. inside the control cabinet, into the individual connectors to be connected to each other is inserted. That is it for example, a current-carrying from the outside of the connector Connect the line and simultaneously via one or more connectors an external power connection for components outside the control cabinet provide.

The object is further achieved according to the invention by a connector for such a feed-through adapter, the connector being a Has socket part and a plug part and for optional attachment in one Base plate of the bushing adapter is designed such that either Socket part or the plug part accessible from an outside of the base plate is.

The preferred embodiments mentioned with regard to the bushing adapter and advantages are analogously to be transferred to the connector. Further preferred embodiments can be found in the subclaims.

According to the views of FIGS. 1 to 3, a bushing adapter 2 has two Rows of connectors 4 on which in a base plate 6 of the bushing adapter 2 are held. The bushing adapter 2 is especially for one Control cabinet, not shown, provided to external in a simple manner Cables and components with internal components of the control cabinet link. The bushing adapter 2 is for this purpose in an opening in the control cabinet introduced and with the base plate 6 on the housing of the control cabinet attached. For this purpose, 6 mounting holes 8 are provided on the base plate.

The base plate 6 has an inside 10 and an outside 11. For connection an external line, this is the bushing adapter 2 from the outside, that is, to the outside 11. From inside 10 internal components connected. On the inside 10 is a tub 12 molded on, which extends perpendicular to the surface extension of the base plate 6. The connectors 4 are guided within this tub 12.

From the view of the inside 10 of FIG. 1 and from the view of the The outside 11 of the base plate 6 according to FIG. 3 shows that the plug connectors 4 multi-pole with different number of poles, three and three in the exemplary embodiment four-pole, are designed. The individual contacts 16 of the connectors are represented by slots. The connectors 4 are on both sides for receiving especially trained by system plugs. The bushing adapter 2 therefore possible both from its inside 10 and from its outside 11 forth the connection with plugs, so that a quick and easy as well secure connection is enabled.

There is a space between the individual rows of connectors 4, which can be used for labeling, for example. On the Inscription fields 20 are provided on the inside 10 for this purpose. Between each Connectors 4 are stiffening ribs 21 for the base plate 6 too know.

On the outside 11, the plug connectors 4 have a peripheral edge 22 on, in particular for sealing the connector against external Influences. In particular, used to seal against moisture and / or foreign bodies to meet the protection level IP 54 according to the standard IEC 529 took the measures known from DE 198 26 453 A1 are.

2, the bushing adapter 2 is in particular as a distributor connector 2A. For this purpose, a bridge 23 is provided, with the help of which individual Contacts 16 of several of the connectors 4 are connected together. The Bridge 23 connects the connectors 4 within the control cabinet. According to 2, the connector 4 shown on the right side serves as a current input E, represented by an arrow. The remaining connectors 4 serve then as current output A, also represented by arrows. The the power input E providing connector 4 must for safety reasons to the outside 11 a connector part 28A with contact pins 30 and on the opposite side have a socket part 28B with contact sockets 32 (cf. in particular Fig. 4). The remaining connectors 4 are reversed trained, that is, oriented towards the outside 11 each have a socket part 28B and opposite each one a plug part 28A. Accordingly has the bridge 23 at the plug connector representing the current input E. 4 a pin contact 23A and 4 for the remaining connectors Socket contact 23B.

4, the special design of the bushing adapter is described below 2 with regard to the possibility of two-sided attachment of the individual connector 4 in the base plate 6 explained in more detail. According to this Figure is the connector 4 inserted in a recess 24 of the base plate 6. Retaining webs 26 are formed from the base plate 6 and form the recess 24 limit laterally and extend vertically from the inside 10. The holding webs 26 preferably form a circumferential around the connector 4 Shaft, wherein an outside is also a wall of the tub 12.

The connector 4 is constructed in two parts, namely it has a plug part 28A with contact pins 30 and a socket part 28B with contact sockets 32 on. The contact pins 30 and the contact sockets 32 form the contacts 16 of the Connector 4. The connector 4 has two housing halves, one first housing half 34A and a second housing half 34B. The first half of the case 34A is the connector part 28A and the second housing half 34B Assigned to socket part 28B. The two housing halves 34A, B are with their connecting ends 36A, B directed towards one another. The Connection ends 36A, B form a connection area.

In this connection area, the two housing halves 34A, B form a locking recess 38, into which a latching web 40 is used to form a latching connection engages, which is integrally formed on the holding webs 26 at the end. For training the locking recess 38 tapers under the end of the first housing half 34A Form a step, the side flank 42 of the step as a wall of the Locking recess 38 and the step base serves as a contact surface 44. On this lies against an end-side contact web 46 of the second housing half 34B, which forms the bottom of the recess 38. The jetty 46 closes a latching hook 48, which is designed to rise obliquely towards the latching recess 38 is. The locking recess 38 is located approximately in the central region of the Connector 4.

The main advantage of the bushing adapter 2 with the connector 4 can be seen in the fact that the plug connector 4 is inserted into the recess 24 on both sides can be inserted so that either the socket part 28B or the plug part 28A is oriented to the outside 11. As a result of the snap connection between Connector 4 and base plate 6 is a simple and quick assembly of the Connector in the base plate 6 possible. This can be done quickly and without major Effort on the special requirements for the bushing adapter 2 be reacted to. In particular, this ensures compliance with safety aspects ensured in a simple manner, which require the contact pins 30 must not be live as long as they are accessible.

Since switchgear cabinets use both different and current outputs are provided, the assembly of the Feed-through adapter 2 with the connectors 4 to the respective control cabinet type be adjusted. With the plug-in connector on both sides 4 need the special requirements when manufacturing the base plate 6 and the individual connecting plug 4 are not taken into account. This can therefore be produced in large numbers for all purposes.

4, the socket part 28B is oriented towards the outside 11. In the Assembly of the connector 4 is this from the inside into the recess 24 pushed. Here, due to the oblique design of the locking hook 48 the retaining webs 26 pushed outwards until the connector 4 is Has reached the end position and the latching web 40 snaps into the latching recess 38 and thus for a secure attachment of the connector 4 on the Base plate 6 provides. In this case, the insertion direction 54 is on the inside 10 directed.

The connector 4 shown in the right half of Fig. 5 differs differs from the plug connectors 4 shown in FIG. 4 essentially in that that the plug part 28A is now accessible from the outside 11 is. For this purpose, the plug connector 4 is inserted into the recess 24 from the outside, until the latching web 40 snaps into the latching recess 38. The direction of insertion 54 is therefore opposite to that of FIG. 4, that is to say Outside 11 directed.

In the left half of FIG. 5, an unoccupied recess 24 is shown.

6 is the reverse arrangement of the locking web 40 and locking recess 38 shown, that is, the arrangement of the locking recess 38 on a retaining web 26 and the arrangement of the locking web 40 on the section shown only Connector 4. The connector is used to form the snap-in connection 4 with this principle, basically from the inside towards the inside 10 inserted into the recess 24 along the insertion direction 54, regardless of whether the socket part 28B or the plug part 28A directed towards the outside 11 should be. When inserting the connector 4, the holding bridge is in turn 26 bent away until the locking web 40 engages in the locking recess 38. For one The connector 4 with two is also easy to assemble in this case Provided housing halves 34A, 34B, the first housing half 34A the Plug part 28A and the second housing half 34B assigned to the socket part 28B is. The latching web 40 is integrally formed on the second housing half 34B, and the exemplary contact 16 is through the second housing half 34B passed through.
