Protective separation device for a rectangular connector

description

The invention relates to a protective separation device for a

Rectangular connector according to the type of independent

Claim 1.

Such protective separation devices are used to selectively disconnect a connector from an associated mating connector in case of mechanical stress to him or his surroundings

To protect damage.

State of the art

In the prior art, for example, from the document

DE 29 505 601 U1 heavy rectangular connector known, which are characterized by a high load capacity and stability. They are used, for example, for high-current applications and are for the transmission of high electrical power, but also for signal and

Data transfers under the toughest requirements and

Environmental conditions. Such rectangular connectors have shielding and mechanical protection usually robust metal housing with a rectangular base profile and are mainly used in the industrial sector.

In the document DE 10 2007 023 019 B4 are still three different versions of substructure housings for

Rectangular connector mentioned. The different versions are the mounting housing, the base housing and the coupling housing. The attachment housing may be mounted, for example, on a wall bushing which contains a contact insert. By the

Locking bar makes it quick and easy

Connection of a sleeve housing with contact insert. The base housing however, is independent of wall feedthroughs and by the independent inclusion of a contact insert to the

Can be used in a wide variety of places and quickly locked by the locking bracket with a sleeve housing with contact insert. The equipped with a locking bracket coupling housing has no flange for attachment to surfaces, for example

Cabinet walls or the like, but serves the fast

Connection with a sleeve housing.

A particularly user-friendly and stable locking bow is disclosed in the document EP 0 731 534 A2. It is characterized by the fact that very high holding forces can be achieved with extremely low actuating forces.

However, such high holding forces may also be their

Have dark sides. For example, a problem may arise if very high cable tensile forces occur as a result of incorrect operation, which are thereby transmitted to the mating connector and can thus cause a great deal of damage.

For example, in the field of car charger generally the application problem is known that an electric car accidentally moves away from a gas pump without having previously unlocked and removed the plug of a corresponding charging cable. Does that dissolve?

Plug connection not automatic, so for example, the pump can be destroyed or it can result in even greater damage

arise. Document DE 10 201 1078 348 A1 proposes a connector assembly with a support structure and a fitting that separate from each other when the connector assembly is subjected to a transverse load above a predetermined threshold. Even in the industrial environment, there is a risk of destruction of a plug connection due to excessive tensile load. Especially in this area continue to exist extremely complex, already permanently installed electrical energy networks, eg. As for production lines and equipment, which are equipped with heavy rectangular connectors and should be operated as interruption free, to yourself

economically profitable and not causing bottlenecks in the production process.

Such rectangular connectors are also known in the art.

The publication US 2004/0141692 A1 discloses a mounting device for mehrkanaüge connection therein both sides latched

highly sensitive optical connector. This has a rectangular frame that can be attached to a wall opening with a bottle, and corresponding inserts.

The publication DE 20 2008 005 250 U1 discloses a rectangular cross-section plug-in connection with a first connector and a plug-in second connector. The first

Connector has a flange plate which is fastened with one or more mounting means on a wall. The second connector is preferably designed for connection of a cable and is designed such that it completely or partially covers with its mating face or the mounting means of the flange plate.

The publication DE 20 2009 014 961 U1 discloses a displaceable securing element for releasably locking a locking element of a rectangular connector. A disadvantage of the prior art is that at the moment, unfortunately, there is no protective separation device automatically separating under mechanical load for such rectangular connectors. In particular, there is a lack of an unobtrusive protective separation device with which already existing and especially already installed

Rectangular connectors can be retrofitted quickly and inexpensively.

task

The object of the invention is to provide a protective separation device for a rectangular connector, which is suitable for inexpensive and inexpensive retrofitting existing rectangular connectors, and which ensures that the connector under high mechanical load is selectively and reversibly separable to

To avoid mechanical damage and to ensure the fastest possible resumption of operation.

This task is governed by the subject matter of the independent

Claim 1 solved.

The protective separation device for a rectangular connector has a mounting housing, which has a first region and a second region, wherein the first region is fixable directly to a surface and / or a base housing and wherein the second region at a

Mating connector housing is locked, wherein the first region and the second region are reversibly separable from each other by the action of a predetermined tensile force.

Advantageous embodiments of the invention are specified in the subclaims.

The attachment housing thus has two reversibly separable areas, namely the first area and the second area. The first area is, in particular with a corresponding first attachment portion, on the said surface, for example a wall, in particular the wall of a control cabinet, but in an advantageous embodiment also fixable to the base housing. The second region can be locked on the mating connector, that is on the mating connector housing.

The invention has the advantage that rectangular connectors against mechanical destruction by particularly strong tensile forces, eg. B.

particularly high cable tensile forces are protected. For this purpose, the first area of the attachment housing is advantageously separated from the second area of the attachment housing in a non-destructive manner as soon as the amount of the predetermined tensile force is exceeded.

A particular advantage of the invention is that a separation of the two areas takes place reversibly. So there is no mechanical destruction. The attachment housing can be immediately assembled and reused manually after such a separation on site, so that the rectangular connector after a successful emergency separation with the least possible effort to restore, d. H. is displaceable in its original state. This is especially true when used in the field of industrial equipment and

Production lines are of great importance, in order to ensure the fastest possible resumption of

Such a rectangular connector can be in cross section

rectangular attachment housing with a first insulating body and a mating connector with a rectangular cross-section

Having mating connector housing and a second insulating body. The first area of the attachment housing can be a first

Have attachment portion and can, in particular with this first attachment portion, on a surface, for. B. on the wall, in particular the wall of the cabinet, fixed, z. B. bolted to it, be. Alternatively, the attachment housing with its first region, in particular with the first attachment portion, on a

Base housing fixed, z. B. bolted to it, be. For this purpose, the base housing having an attachment opening, to which the

Attached housing, in particular screwed, is. The

Base housing, in turn, for example, with an associated Anschraubflansch, on a surface, for. As a wall, be screwed. The base housing may further comprise a lateral cable inlet, for example, in order not to function in a

Cable passage through the surface, for example by a

Wall opening to be tied.

The first insulating body can therefore be wired, for example, on the control cabinet side or on the base housing side, and can preferably be connected to the first region of the attachment housing, in particular to the associated first one

Attachment section, attached or at least attachable. In this case, the first insulating body directly or indirectly, for. B. over

Fasteners such. B. bolts, on the first

Attachment section attached or attachable.

Preferably, the first region has a plurality of bolts for fixing the first insulating body. For this purpose, the first fastening section can have a plurality of screw openings or through openings, advantageously with associated nuts or screws, for fastening the

Having bolt on the first mounting portion.

For example, the bolts may be screwed with their first end to the through holes of the first mounting portion. The first insulating body can then, for example, with a belonging to the insulating flange, attached to the respective opposite second ends of the respective bolts, in particular screwed, be. The first insulating body may have a plug side and opposite a cable connection side. The flange of the Insulating body can be arranged for example on the cable connection side or between the cable connection side and the mating side of the insulating body.

The first attachment portion may have a window on which the first insulating body is arranged with its cable connection side, or through which it protrudes.

In one possible embodiment, it can be so on the first

Fastening portion mounted first insulating body preferably in part in the attachment housing and / or in part, in particular with his

Cable connection side, on the opposite side of the first mounting portion, so z. B. on the cabinet side, are. On the other hand, if the attachment housing is mounted on a base housing, the first insulating body may possibly be located at least partially in the attachment housing and / or at least partially, in particular with its cable connection side, in the base housing. For this purpose, the first insulating body protrude through the first window.

In a preferred embodiment, the first insulating body with its opposite the direction of insertion facing cable connection side to

Wiring arranged on the first window and protrudes with its mating side for connection to a mating connector housing arranged in the second insulating insulator in the insertion direction from the second region of the

Attachment housing out. In this case, the insulating body can be located with its cable connection side in the mounting housing, but advantageously be arranged so close to the first window that a wiring without disassembly of Isolierköpers is easily possible.

Furthermore, the first attachment portion may have a plurality of first

Have through openings. By virtue of these first insertion openings, screw threads can be correspondingly provided, for example Fastening means are plugged, which serve for screwing the first area to the surface, in particular the control cabinet wall, or to the base housing. The attachment of the first Isolierköpers on the first region is basically advantageous because the first insulator with its kabelanschlussseigen wiring thereby in the case of

Emergency separation on the attachment side remains.

Another advantage of the invention is that existing and already wired power distributions can be retrofitted with a solution according to the invention with little effort, such as to adapt them to appropriate safety standards. Of the

Mating connector can remain completely unchanged with its mating connector housing and its cabled second insulator located therein. The first insulating body and its wiring can usually remain as well. This saves a lot of time and money compared to a complete reinstallation. to

Retrofitting the rectangular connector has only one

Conventional mounting housing an already installed connector are exchanged for a mounting housing according to the invention. This has the advantage that the retrofit is associated with very little effort.

In an advantageous embodiment, the optional existing base housing can be exchanged for an advantageously modified base housing during retrofitting. Although this is not mandatory for the separation function according to the invention, but may be in terms of design details such. As the housing seal, prove advantageous.

Optionally, a combination of a base housing and a mounting housing in the assembled state as a system be replaced for retrofitting. This may have the advantage of saving time during retrofitting.

For the attachment of the attachment housing can in the base housing

existing fasteners exist and can be offset in a preferred embodiment with respect to the mounting hole, arranged so that there is an offset between the fasteners and the mounting hole. The fastening elements may, for example, be webs which, directed away from the mounting opening, are formed in the socket housing and formed in the housing and have a screw hole in their longitudinal direction.

In an advantageous development, the first area of the

Attachment housing on the already mentioned first attachment portion. This can be carried out in particular flat and preferably in one piece and, for example, of a metallic material, for. B. made of sheet steel or aluminum. The first

Fastening portion may in particular have a thickness, which optionally the said offset of the screw elements of

Base housing corresponds. The first mounting portion may be used to support an improved housing seal preferably form-fitting manner in the base housing and particularly advantageous plan complete with its mounting opening. The first

Attachment portion may have the already mentioned first window, which is arranged in particular centrally in the first attachment portion. Through this window, the first insulating body protrude in the assembled state. Preferably, the first window may have a substantially rectangular shape in order to embrace the first insulating body, which preferably has a substantially rectangular cross-section, in a particularly space-saving manner. In a first aspect, the first attachment portion serves to fix the first region, for. B. on a surface, such as the wall, in particular the wall of the cabinet. The first

Attachment portion may advantageously be designed so that it also allows the option of attachment to the base housing. This attachment can be done via a screw. For this purpose, the first attachment portion have a set, in particular four, first through openings, through which he ans ans said surface, z. As the control cabinet wall, or even to the base housing can be fixed, in particular screwed.

On the other hand, the first attachment portion of the attachment of Isolierköpers serve. For this he can continue a sentence

Screw holes that are characterized by an internal thread, or second through holes, z. B. with one associated

Nut or screw, for screwing in or screwing the

Own bolt. The bolts can thus be fixed with its first end to the first attachment portion. At one

opposite second end of the bolt, the first insulating body, for. B. with its plug-in area, be held and at the same time with its cable connection side through the first window of the first attachment portion through and so in the assembled state z. B. protrude into the cabinet or the socket housing and so be partially disposed therein.

In a preferred development, the first region has at least one first latching element and the second region has at least one second latching element, wherein the first and the second latching element can be latched together and reversibly separated from each other by the action of a defined separation force. In an advantageous embodiment, the first region has a set of first latching elements, which are designed in particular as part of guide pins. Each of these guide pins has at a first end a screw portion, in particular a cylindrical

Threaded section with a screw thread, and on one

opposite second end said first locking element, which may be embodied for example in the form of a locking pin. Thus, the guide pins can fulfill a dual function, namely on the one hand the first portion of the attachment housing on the surface or on

To fix socket housing, in particular to screw, and on the other hand with the second region, in particular with the second region belonging to the second locking elements, reversibly to lock. For example, each second latching element may have a matching, in particular substantially cylindrical, latching recess, which is suitable in each case with the respective latching pin of the

Locking guide pin and detent it again under the influence of a defined release force. For example, the second latching element can have a cylindrical shape as a whole and can be screwed onto the second area, in particular to a second fastening section of the second area.

The amount of the predetermined tensile force, which leads to the separation of the two areas of the attachment housing, can be determined from the sum of the separation forces of the individual locking element pairs. If that

Mounting housing, for example, has four identical first locking elements and four identical second locking elements, the predetermined tensile force can be four times the release force of a single locking element pair, consisting of a first and a second locking element.

From the sum of the individual separation forces thus results in the entire tensile force that must act on the rectangular connector in order to trigger a protective separation. Of course, in an alternative embodiment, the latching recesses may be disposed on the first latching elements of the first region and the latching pins on the second latching elements of the second region.

The second area may be a preferably rectangular frame

exhibit. This frame is suitable with first

Locking means of the mating connector to lock and has for this purpose second locking means.

In an advantageous embodiment, it may be in the first

Locking means of the mating connector to locking bracket and in the second locking means of the second area to

Act lock pin. As a result, the desired high

Holding force even with comparatively low operating force

be guaranteed.

In a preferred embodiment, however, the locking is a screw, so that the first locking means z. B. by one or more Gehäuseanformungen with one each

Schraubdurchlass and a corresponding locking screw and the second locking means by a screw opening, z. B. a screw hole with a matching internal thread is formed. In particular, the frame may have one or more projections for this purpose. In these formations then the

Screw holes for screwing be arranged with locking screws of the mating connector.

On the inside, the frame may have means for attaching the second

Own locking elements. These means are advantageously suitable for the second locking elements, in particular during the unlatching process especially stable. For example, it may be the second attachment section already mentioned. This one can be in

Direction of the frame plane, ie perpendicular to the insertion direction, preferably on a side facing the first region side of the second region, in particular the frame to be arranged. For example, the second attachment portion in the form of an inner flange on

Be frame running circumferentially. In other words, the second attachment portion is flat and has

Advantageously, a preferably substantially rectangular running and arranged centrally in this area second window. This second window can in particular be larger in the longitudinal direction than the first window, so that when assembling the two areas, the bolts of the first fastening portion can project through the second window with the first insulating body held thereon. Thus, the first insulating body with its plug side through the second window in the second area, in particular in the frame of the second area, or even into the second area,

in particular the frame of the second area, protrude, and so z. B. protrude when plugged into the mating connector.

Furthermore, the second attachment portion second

Through openings for passing through the first locking elements, in particular the guide pins, have. At the second

Through openings, the second locking elements can be arranged, in particular screwed. In particular, the second latching elements can be located on the side of the frame, that is to say located substantially within the frame, so that the first latching elements, in particular the guide pins with their latching pins, pass through the second through-insertion openings of the second fastening section

hindurchsteckbar and thereby latched to the second locking elements. This has the advantage that the second locking elements in

Unlocking process are held particularly stable on the second area, in particular, because they are engaged behind by the second attachment portion.

Since mounting housing advantageously has a substantially rectangular shape, in particular outer contour. For example, the frame of the second region may have two parallel long sides and at right angles thereto two short sides parallel to each other. The corners of the frame may be rounded, for example. Accordingly, the first and second attachment portions may have a substantially rectangular shape with rounded corners. The first and second windows may have a substantially rectangular shape. At two diagonally opposite corners of the frame may for example have the projections with the screw holes for locking with the mating connector, wherein its in

Essentially rectangular basic shape is maintained because it can interact with the other rectangular connector system accurately. For example, the thus formed substantially rectangular shape of the attachment housing is of course particularly advantageous for use as a protective separation device for a rectangular connector.

The figures contain partially simplified, schematic representations. In part, for the same, but possibly not identical

Elements identical reference numerals used. Different views of the same elements could be scaled differently.

1 a and 1 b show a rectangular connector with a mating connector housing 3, and a first region 1 and a second region 2 of a mounting housing 100 from two different perspectives. FIG. 1 c shows the attachment housing 100 composed of the first area 1 and the second area 2.

In Fig. 1 a is particularly well seen from an oblique plan view, as a first insulator 41 at the first region 1 of

Attachment housing is attached. The first region 1 has for this purpose a first attachment portion 12, are screwed to the four bolts 15 with its first end. In this illustration, however, are only see three Schaubolzen 15, because the fourth is covered by the insulating body 41. At the second end of this bolt 15, the first insulating body 41 is bolted to its unspecified flange to the bolt 15. This illustration allows a view of the mating side of Isolierköpers 41st Furthermore, the first area has four guide pins 16, of which only three guide pins 16 can be seen in this illustration, because the fourth is covered by the insulating body 41. These guide pins 16 have at their first end a screw portion, namely a cylindrical portion with a

Screw thread, with the guide pins 16 through

Through openings 122 of the first attachment portion 12 are inserted and facing the direction of insertion. Thus, the first region 1 of the attachment housing 100 on a surface or on a

Base housing 5 are fixed, which is shown explicitly in Figs. 3a and 3b. At its second end, the guide pins 16 have first latching elements in the form of latching pins for latching with the second

Locking elements 26 of the second region 2 of the attachment housing 100th

This second area 2 has a frame 28, which is made substantially rectangular. It has a rectangular inner contour, the corners are slightly rounded. Furthermore, it has a rectangular outer contour, which is also rounded at two diagonally opposite corners. At the other two diagonally

opposite corners are projections 281 with

Screw holes 283 arranged for locking with the mating connector 3.

The mating connector 3 has a mating connector housing 38 with

Schraubanformungen 381, each with a screw passage, in each of which a locking screw 33 is arranged. 1 b shows the rectangular plug connection from a counter perspective, in which inter alia the cable connection side of the first insulating body 41 arranged on a first window 124 of the first fastening section 12 can be seen through said first window 124, which is not designated here for reasons of clarity. For a better understanding, the first region 1 with its first window 124 in FIGS. 4a and 4b is shown particularly clearly and explicitly designated. The first insulating body 41 is, as already mentioned in the description of the preceding illustration, at the first area 1 over the

Bolt 15 attached. The mating connector 3 has a second insulating body 43, the plug side is easy to see in this illustration. This is plug-compatible with the mating side of the first Isolierköpers 41st

The first area 1 and the second area 2 belong together to the mounting housing 100. In this illustration, however, they are still

separated from each other, so not yet locked on their locking elements 16, 26 with each other.

In contrast, FIG. 1 c shows the assembled attachment housing 100. For this purpose, the first area 1 with the insulating body 41 attached thereto is inserted into the second area 2 and latched thereto. For this purpose, it engages with its guide pins 16 through a second fastening portion 22 of the second region 2 through its second through openings 222 into the recesses 261 of the second locking elements 26 of the second region 2. The locking pins of the guide pins 16 then latch in the recesses 261 of the second locking elements 26th For a better understanding, the second area 2 with its second through-openings 222 and the second latching elements 26 with their latching recesses 261 in FIGS. 6a and 6b is shown particularly clearly and explicitly designated. 2a, 2b and 2c illustrate the functionality of the protective separation device in three snapshots. The rectangular connector includes the said base housing 5, the mounting housing 100 and the

Mating connector 3. In this case, the first area is 1 of

Attachment housing 100 by a screw connection by means of

Screw thread of its guide pins 16 attached to the base housing 5. The base housing 5 further has a Anschraubflansch 55, with which it in turn can be mounted on a surface.

In FIG. 2 a, the second area 2 is latched to the first area 1 and together with it forms the attachment housing 100

Attachment housing 100 is attached to an attachment opening 51 of the base housing 5, which is particularly well visible in Fig. 3a. The mating connector 3 is just before, with the mounting housing 100th

plugged together and bolted by means of its locking screws 33 in the screw holes 283 of the attachment housing 100 for locking, as shown below in Fig. 2b. There is the mating connector 3 with the second region 2 of the

Attachment housing 100 firmly locked by the said screw.

In Fig. 2c an emergency separation is shown. The

Mating connector housing 3 is pulled away with a predetermined tensile force from the base housing 5. As a result, the two areas 1, 2 of the attachment housing 100 are separated from each other. The first area 1 remains with the first insulating body 41 by its screwing to the bolt 15 on the base housing 5. The second area 2 remains by its locking, which in this case by the said

Screw connection, at the mating connector 3.

In this emergency separation, the individual locking elements 16, 26 are separated from each other. This happens each with a defined

Separating force. Since there are four identical pairs of locking elements 16, 26 is, the predetermined tensile force is four times the defined separation force of the individual locking element pairs 16, 26. Thus, the

Plug connection non-destructive and reversible be separated at a given tensile force.

Fig. 3a shows the base housing 5 separately in an oblique

Top view. In addition to its Anschraubflansch 55 has the

Base housing 5 a side cable inlet 56. This allows the connector to be operated independently of a wall opening. Furthermore, the base housing has fastening elements for fastening the first area 1 of the attachment housing 100. The fastening elements are webs 52, which are of the

Attachment opening 51 directed away in the base housing 5 extending into this formed and have a running in its longitudinal direction Schraubbohrung 53. These webs 52 are opposite to the

Attachment opening arranged offset, so that between the webs 52 and the mounting hole 51 an offset Δ exists. That's it

Base housing 5 advantageously modified to receive by means of this offset Δ the first mounting portion 12 positively. This contributes, for example, to the particularly good sealing of the base housing 5.

Fig. 3b shows the advantageously modified base housing 5 in comparison to a base housing 5 ^' , in which no offset Δ exists. Also on this base housing 5 ^' , a mounting housing 100 with the first mounting portion 12 of its first portion 1 are screwed. However, this first attachment portion 12 is then not form-fitting receivable and the base housing 5 ^' is characterized less well

sealed. When retrofitting an existing

Rectangular connector, such a base housing 5 ^' can be exchanged for an advantageously modified base housing 5. there can on the advantageously modified base housing 5 already the

Attachment housing 100 must be screwed to make the exchange as ergonomic as possible for the user.

FIGS. 4 a, 4 b and 4 c show the first fastening section 12 without and with the four threaded bolts 15, which are screwed to the first through-openings 121 with nuts 123. Furthermore, the first attachment portion 12 has four first insertion openings 122 for

Screwing to a surface or to the base housing 5 by means of the guide pins 16. In the first mounting portion 12 is centrally a first window 124 for wiring the first Isolierköpers 41st

arranged to be attached to the bolt 15.

FIGS. 5a and 5b show the base housing 5, into which the first region 1 of the attachment housing 100 is inserted in a form-fitting manner. The first region 1 comprises the first attachment portion 12 with the

Bolt 15. In Fig. 5b, it is still by means of

Screw thread of its guide pins 16 screwed to the screw holes 53 of the webs 52 of the base housing 5. Thus, the first area 1 of the attachment housing 100 is fixed to the base housing 5.

FIGS. 6a and 6b show the second region 2 of the attachment housing 100. This has a frame 28 and a therein

arranged flat second mounting portion 22 with a second window 224 and four second through-openings 222. Through the second window 224 has the second mounting portion 22 in the form of an inner flange.

As shown in FIG. 6 b, the second latching elements 26 are arranged on the second push-through openings 222. For their attachment to the second attachment portion 22, the second latching elements 26 are thereby screwed into the second through-insertion openings 222. To have the second through-openings 222 each have an internal thread and the second locking elements 26 have a matching external thread.

FIGS. 7a and 7b show the first and second regions 2 of FIG

Attachment housing 100 before their common locking. In FIG. 7b it can be clearly seen that the guide pins 16 are suitable for coming from the direction of the second fastening section 22 and the second through-openings 222 penetrating into the second through-insertion opening 222

Locking recesses 261 of the second locking elements 26 to be inserted and to lock it with their locking pin therein. Conversely, the second locking elements 26 are unlatched from the second

Fixing portion 22 held particularly stable because they are on the side facing away from the first region 1 side of the flat second

Mounting portion 22 are arranged, so are engaged behind by this 22 during Entrastungsvorgang.

Furthermore, it can be clearly seen that the second window 224, at least in the longitudinal direction, is larger than the first window 124, so that when

Assembly of the two areas 1, 2, the bolts 15 of the first mounting portion 1 can protrude through the second window 224.

In Figs. 8a and 8b, the assembled mounting housing 100 is shown without and with the insulating body 41 attached thereto.

In Fig. 8a is clearly visible as the bolts 15 through the first window 124 in the second region 2 of the attachment housing 100th

protrude.

In Fig. 8b is shown how the insulating body 41 attached thereto protrudes through the second region 2, so as to project in the mated state into the mating connector 3 and to be plugged with the second insulating body 43. Protective separation device for a rectangular connector
