description

System connector formed from a first support frame in which electrical contacts are held in separate plug-in modules, wherein the first support frame is protected by a surrounding housing from environmental influences, provided for contacting with plug-in modules which are held in a second support frame.

Such a system connector has been designed with a view to simplifying its assembly, and to form plug-in connections with plug-in modules in a housing to meet the requirements for an industrial environment.

State of the art

From EP 0 860 906 B1 a holding frame for connector modules for installation in connector housing is known, which has a mounting frame made of hingedly interconnected halves, can be used in the connector modules.

Furthermore, from US Pat. No. 7,316,591 B2, a plastic-fabricated holding frame is known in which a plurality of plug modules to be arranged next to one another are held between wall segments separated by slots.

A certain disadvantage of such known holding frames is that they are always to be inserted into another housing and screwed there. In addition to the current flow direction and thus on the

CONFIRMATION COPY Mounting direction of the inserted in the plug-in modules contacts must be taken, and that always a predetermined installation direction of holding frame was predetermined to the connector housing. task

The invention is therefore based on the object to form a connector housing construction, which does not require separate fastening means and a mounting of contact-equipped modules from the plug side as well as the connection side of the respective plug part allows light, wherein the current flow direction is in principle independent of the contact training ..

This object is achieved in that in each case a rectangular bushing with devices for holding the plug-in modules are provided in the first support frame and in the second support frame, that in each case a plug insert is arranged in the rectangular feedthrough, within which the plug-in modules inserted into the support frame and can be fixed in the rectangular feedthrough, and that the plug-in modules can be inserted into the rectangular feed-through on both sides, from the plug-in side as well as from the connection side.

Advantageous embodiments of the invention are specified in the subclaims. The invention is a system connector which is disclosed in US Pat

Plug-in modules contains contacts, the plug-in modules are plugged into a holding frame and exchangeable. While one of the support frame is fixedly mounted as a flange frame in a device to be supplied, a second support frame with a plug housing is protected against environmental influences and with a corresponding electrical

Mobile cable with the built-in holding frame connectable.

Regardless, however, a plug connection of two cable connectors is also conceivable. While plug-in modules are initially held in a separate frame in similar connector constructions and the frame is to be screwed in a further housing part provided for this purpose, the embodiment according to the invention has a frame which can be used as a holding and housing frame holding the modules, and / or connectable to a connector housing.

However, both support frames have the same system for receiving inserted therein plug-in modules.

For this purpose, each holding frame includes a plug-in insert which is fixed on the three sides with corresponding latching and contact contours on one side within a rectangular feedthrough in the holding frame.

In the U-shaped angled side frame of the plug-in tongues are formed in each case at the upper and lower edges, the ends of which are spaced and oriented obliquely into the rectangular passage, aligned.

Advantageously, the plug-in modules have longitudinal ribs by means of which the modules can first be inserted between the tongues of the plug insert into the holding frame in order subsequently to be displaced laterally (transversely to the plug-in direction) by means of integrally formed transverse ribs on the modules. Wherein the rectangular recess is ultimately complete with plug-in modules.

The insertion process is carried out without tools.

Since the orientation of the plug-in modules within a plug connection in

Plug insert and in the holding frame is to be provided in mirror image, is everyone

Plug insert designed so that the plug-in modules are used only in the insertion direction rotated in the rectangular recesses.

Furthermore, it is advantageous that the plug-in modules can also be inserted from both sides into each of the holding frames - that is, from the actual plug side with the mating plug as well as from the cable connection side.

Another advantage of the plug-in insert according to the invention is that it also has devices for a PE connection without tools in the simplest way - ie the transfer of a protective line - ord- properly. In this case, a version is provided in which an electrical conductor with a crimp connection is pluggable connected to the plug insert and another version in which an electrical conductor, as a stranded conductor, can be plugged and contacted directly by means of an already known device.

The housing frame is designed as a cantilevered first support frame 10 and includes i.a. a latching unit 4 integrated therein, the mechanism of which is achieved by means of a pressure and rotary knob technique.

Within a rectangular feedthrough 11 of the holder frame 10 several plug-in modules 40 are arranged, which correlate with plug-in modules 40 'of a matching, second holding frame 20.

Wherein the flange frame is stationary to be incorporated into any aggregate, such as a motor or cabinet housing, and the mobile system connector to the housing frame (holding frame 10) with the stationary flange frame (second holding frame 20) is to be connected.

Each of the holding frames 10, 20 is designed for use with the plug-in modules 40, 40 'and designed with corresponding contours for installation in the semicircular plug housing 3 or for a cutout in a housing.

Wherein formed as a second holding frame 20 flange frame has a circumferential flange 22 with a collar in which a circumferential sealing ring 23 is arranged, for reliable sealing of the connector against environmental influences. Furthermore, the plug-in side 6 and the cable-side connection side 7 is marked.

2, the holding frame 20 of the system connector is shown, with its conspicuous rectangular feedthrough 11, within the peripheral flange 22, in which a plug insert 30 is inserted.

In this case, the plug-in insert 30 is latched as a U-shaped component with right-angle bent side frame 31 in one of the narrow side regions in the holding frame. In Fig. 3a, a corner cutout of the holding frame 20 is shown with a view of the mating side 6.

The detail shows several formations, which are responsible for the installation of a plug-in insert 30 and for the functionality of the system. Such is a partially freestanding pin 26 with a polarizing rail

26 'shown as a recess 29 and a square elevation thirteenth

Fig. 3b shows the same section within the rectangular passage with the electrically conductive part designed as a plug insert 30 which is held by means of the locking tabs 33 and pin 26.

The plug insert 30 is here inserted from the plug side 6, from above into the rectangular feedthrough 21.

In this case, the plug insert 30 is pushed at its corner behind each one of the molded pin 26 and at the same time by means of a Rastla- see 33, which engages in recesses 29 in the holding frame 20 so that a further displacement of the plug insert 30 is prevented.

FIG. 4a shows two plug-in inserts 30, 30 'in a perspective view, as they are arranged in the holding frame 10, 20 in a plug-in system. In this case, the plug insert 30 'only the mirror image

Differences.

In the side frame 31 each two of the upper and lower frame edge 32 inwardly aligned tongues 34 are formed, wherein the tongue ends 35 spaced from each other in the interior of the rectangular passage 11 have.

The square with rounding formed elevation 3 on the longitudinal sides of the holding frame 20 - which also applies to the first holding frame 10 - which protrudes into the center of the tongues 34 of the side frame 31, in fact constitutes a limitation of the four tongue ends 35 of the plug insert 30, 30 ' , and is at the same time the pivot point after inserting the plug-in

Module 40 from the vertical to horizontal displacement within the holding frame 10 or 20. Furthermore, at least on one side of a plug insert 30, 30 'contact tabs 37 are provided in a wavy design, the contact with the other plug insert when plugging the two housing frame 10, 20.

As can be seen from FIG. 4b, the tongues 34 are arranged in the side frames 31 of the plug insert 30, 30 'for the two holding frames 10, 20 such that the side frame 31 shown here above has a polarization gap 39 on its outside (which, however is as wide as the central gap 39 '), while the lower side frame 31, the polarization gap 39 is arranged inside near the angle.

In the two gaps 39, 39 'formed on narrow sides of a plug-in module 40 longitudinal ribs 45 are used.

For this purpose, it is shown in FIG. 4c how the longitudinal ribs 45 and the transverse ribs 43 engage in the side frames 31 of the two plug-in inserts 30, 30 'from the plug-in modules 40.

Each of the plug-in modules 40 has short longitudinal ribs 45 at the edges of the narrow sides 41 and approximately centrally of the narrow sides two spaced by a groove 44 transverse ribs 43.

For insertion of the two holding frames 10, 20, the plug-in modules 40 are first inserted perpendicular to the respective support frame in the region of the plug insert 30 by means of the longitudinal ribs 45 and guided to subsequently by means of the transverse ribs 43 and the groove 44 disposed therebetween, at two within the Holding frame 10,20 oppositely molded slide rails 14, 14 'and 24, 24' to stop in the rectangular feedthrough 1 1, 21 to be moved.

By the intervention of the longitudinal ribs 45 between the tongues 34 and the polarizing gaps 39, 39 ', first a possibility for a confusion-free polarization of the plug-in modules 40 to be inserted is secured. The longitudinal ribs 45 on the narrow sides 41 of the basically similar Chen or identical plug-in modules 40, 40 'formed asymmetrically to the width of the module housing.

In addition, for confusion safe plugging, one of the pins 16, 26 in the holding frame 10, 20 provided with an additionally molded polarizing rail 16 '26', which prevents a false plug, because the plug-in module 40, 40 'is made narrower for this area on the opposite side, in which the pin 16, 26 has no additional molded rail. (See also Fig. 3b)

Furthermore, it can be seen from FIG. 10 that z. B. the slide rails 24, 24 'have a different length, so that only the narrower side of a plug-in module in the corresponding recess between the pin 26 and the longer slide 24 can be inserted.

This ensures that two in each case in the mutually inserted holding frame, oppositely arranged plug-in modules are not interchanged pluggable and lead to the destruction of components or equipment.

5 shows in a perspective view and in a partial section of the holding frame 10, 20, as two plug-in modules 40, 40 'are the side rotated by 180 ° against each other in the two holding frame. In this case, one of the side frames of the plug is not shown.

Clearly visible are the respective offset longitudinal ribs 45 on the narrow sides 41 of the plug-in modules 40, 40 'are.

It can also be seen how the plug-in module 40 can be moved horizontally on the slide rails 4, 4 'or 24, 24' after the vertical insertion by means of the groove 44 and the transverse ribs 43 separating them.

For the transfer, or for forwarding the protective effect of a prescribed PE protective conductor within the connector, a special connection of the protective conductor is provided on the plug insert 30, as indicated in FIG. 6.

On the one hand there is the possibility to connect a crimp contact 56 with a corresponding electrical conductor and this crimp contact 56 in a square recess 17 z. B. in the holding frame 10 inserted. gene, and the plug insert 30 by means of two U-shaped bent contact tongues 38 to contact.

On the other hand, a further, rectangular recess 18 is provided in the holding frame 10, in which an already known and otherwise used connection element 58 can be inserted, which is provided for contacting electrical conductors, which are known as stranded conductors.

Also for this purpose, two U-shaped contact tongues 38 'are provided on the plug insert 30, which extend into the connection element 58 for contacting.

Both connections for PE contacting take place via the cable connection side 7 of the first 10 as well as the second holding frame 20 not shown further here. FIG. 7 shows an example of two plug-in modules 40, 40 ', wherein a first plug-in module 40, 40' is shown. Module 40 pin contacts 55 and a second plug-in module 40 '(not visible) socket contacts contains. In this case, the second plug-in module 40 'is provided with the socket contacts with a collar 47 which can be inserted into a corresponding recess 48 of the first plug-in module 40, for contacting with because pin contacts 55th

In addition, a variant may be provided in which both plug-in modules are equipped with pin or socket contacts, and a separately manufactured adapter is also designed collar-like, which is snapped onto one of the plug-in modules 40. For this purpose, this adapter is then equipped with each opposite contacts to the contacts in two plug-in modules.

To remove one or more plug-in modules 40 from one of the holding frames 10, 20, a bow-shaped disassembly tool 50, as shown in Fig. 8, required.

Meanwhile, parallel to the narrow sides 41 of the plug-in modules 40, 40 'angled side bracket 52 is pushed over the narrow sides of the inserted plug-in module 30 plug-in module 40, 40'. The tongues 34 are bent on the plug insert 30 to the outside, so that their latching on the transverse ribs 43 from the plug-in module 40, 40 'is repealed and the module from the plug insert 30 and thus from the respective support frame is removable.

The nearest plug-in module 40 must first be moved laterally for removal in the region of the plug insert 30 before the latching of the tongues 34 can be lifted with the disassembly tool 50.

Where provided, the plug-in modules can be pulled out of the respective frame either on both sides.

So, in the insertion direction 6 or opposite in the direction of the connection side 7 of the respective support frame 10, 20th

Moreover, in a second embodiment, a plug-in module 40 "as shown in FIG. 9, provided that for certain applications not laterally within the support frame 10, 20 should be displaced, but only in the region of the plug insert 30 in or against the Insert direction is.

For this purpose, the two transverse ribs 43 have been pulled together on the narrow sides of the module to form a transverse rib 43 ', so that no groove is available for displacement on the slide rails 14, 14', 24, 24 '.

In both support frames 10, 20 of this connector, a mechanical coding with two pentaprism posts is further provided to a mating connector housing at a mating together

Differentiating feature for a correct connection to be able to claim.

For this purpose, at least one 5-edged coding post 60 is provided in each holding frame 10, 20 on the plug side, as shown in FIG. 10, which is split longitudinally in each case halfway, and in a certain mutually matching

(or even inappropriate) angle is pluggable, so that only the appropriate angular position allows each other to plug the two housing parts. In this case, number symbols are provided for the different angular positions, which are numbered in the proposed 2-part coding system with the numbers 0 - 4 for the first post and for the second of 5-9. This allows up to 25 combinations.

Furthermore, in the plan view of the support frame 20 designed as a flange frame, a plug insert 30 with a plug-in module 40 inserted therein is shown.
