Description

TECHNICAL AREA

The invention relates to a housing for connectors, the are provided with a coding device. The housing is intended for pluggable connection to mating connector, those in electronic bays according to the 19-inch system available. These bays are in subracks used according to this 19-inch system. The Connectors are so-called D-subminiature connectors according to DIN 41 652.

STATE OF THE ART

From DE 298 19 972 U1 a connector housing is in the 19-inch device system known, in the standardized according to DIN 41 612 Connectors can be used. To ensure, that such a housing on the right one Is plugged into the connector in the Front panel of an electronic slot is placed, and consequently no swapping between slots can occur, this connector system has a coding device. The coding device consists of a first Coding part, which is attached inside the housing. The Counter-coding part is attached to the circuit board and cantilevered towards the coding parts located in the housing out. The coding parts and the counter coding parts are formed into one another. It can be done by different Rotary positions of the coding parts inserted into each other different encodings are made possible. A such coding device is on the inside of each placed on both ends of the housing. The coding has the advantage that they are inside the housing and thus from is protected outside. However, it's constructive Training relatively complex. In addition, one is appropriate large housing required because in addition to that Connector still room for said coding devices in the Must be present inside the housing. The disadvantage is also the encoding device sunk in the housing, since the respective coding setting is not from the outside is easy to recognize.

Another connector housing is known from DE 299 08 277 U1 known with a coding device that also is designed for connectors standardized according to DIN 41 612. The coding device of this housing has a cantilevered shape projecting cantilever walls on the front of the housing. This Cantilever walls have perforations through which cantilever pins are inserted can be. Depending on the presence of such Coding pins can be the housing in question on the Put on the circumferential collar of a counter housing or not put on. In the collar of the counter housing are namely Through holes in the cantilever walls there are comparable holes, in which coding pins are optionally used are. Unless in the holes that are in the collar of the counter housing are present, coding pins are inserted, can not also in the axis with the Bores of the collar aligned through-holes in the cantilever walls Insert coding pins. The correct coding position can in contrast to the above prior art relatively easy to recognize on the outside, but builds also this case compared to a comparable one, not provided with a coding device larger. This Coding device is therefore just like the one above Coding device for housings known from the prior art, which are equipped with D-subminiature connectors, not suitable.

PRESENTATION OF THE INVENTION

Based on this prior art the invention has the object of a good from the outside specify coding system for connector housings, which for D-subminiature connectors according to DIN 41 652 are designed.

This invention is by the features of the sibling Claims 1 and 9 given. Developments of the invention are the subject of subsequent claims Dependent claims.

The coding device according to the invention has the advantage that the respective coding position is clearly visible from the outside. In addition, the length of the housing changes not by this coding device. The provided on the housing Coding parts can be designed identically to one another his. In particular, as in the drawing is shown to be aligned with one another.

All coding devices of the housing, the cantilevered parts from Cantilevered cover part or bottom part of the housing can stand away within the from the cover part and the Bottom part defined, parallel to the front opening of the housing aligned cross section. Thereby need neither the length dimension nor the width dimension of the housing by the coding device according to the invention to be enlarged.

The cantilever parts can be made in one piece with the cover part and / or the bottom part of the housing each be made and thus be part of the lid or the bottom part. Each cantilever part preferably has a material Weakening area through which it can be canceled. On in this way, optional cantilever parts can be removed according to the desired coding position.

When the connectors and connectors are plugged together Mating connector, i.e. in the attached state of the Housing on the front panel of a slide-in, protrude Coding parts of the housing and those on the front panel Coding parts towards each other. Where coding parts of the Housing are present, no coding parts of the front panel to be available. This is a mutual removal of coding parts - on the one hand, those on the housing and on the other hand the one on the front panel - required.

The counter-cantilever parts on the front panel can be attached be attached to the front panel. For example, cantilever parts in Form of pins or wall parts, for example in the Front panel inserted from the direction of the housing respectively not be plugged in.

According to an embodiment also shown in the drawing can the counter-cantilever parts on one to the front panel separate holding part be available. This holding part can on the front panel, for example, attached in particular be screwed on. These fastening or screwing areas can be the screw points at which the mating connector screwed to the front panel becomes. Then you need additional screw points on the front panel not to be provided. The holding part can from the outside of the front panel or what's in the drawing is shown from the back of the front panel on the same be screwed on. The rear attachment of the Holding part on the front panel has the advantage that Holding part is not disturbing on the front panel and possibly plugging the two connectors together hindered or structurally difficult. To the Holding part, the cantilever parts are attached as counter-cantilever parts. If the holding part is attached to the back of the front panel the counter-cantilever parts of the holding part protrude the recess on the front panel in which the connector sits, through. These counter-cantilever parts can also be used with each other equally trained and, for example, in groups be aligned. These are preferably counter-cantilever parts made in one piece with the holding part. To the easier removal or cancellation of such Counter-cantilever parts can - as is also the case with the The case may be - areas of weakness have been incorporated. The Counter-cantilever parts can be in the form of pins or in the form of Wall parts should be formed. To prevent not correctly removed cantilever parts and counter cantilever parts the same when plugging the connector together of the mating connector can slide past each other especially the counter-cantilever parts at their free end possess bent end area. That way is a Pushing cantilever parts past counter cantilever parts and thus the plugging together of connectors that do not match practically excluded.

Further refinements and advantages of the invention are the in the claims further listed features and the The following exemplary embodiments can be found.

WAYS OF CARRYING OUT THE INVENTION

A housing 10 consists of a lower part 12 and a Cover part 14, which are connected to one another via a plurality of screws 16 are screwed. While the lid part 14 essentially is more or less flat, that is Lower part 12 pot-like, with a bottom part 18 and each to the left and right side part 20, 22 formed. The cover part 14 closes the two Side parts 20, 22. The housing 10 has in the longitudinal direction a length L and a width B in the transverse direction.

In the area of its lower forehead opening - with reference to FIGS. 1, 2 24, a plug connector 26 is seated in the housing 10. This connector 26 is a so-called D-subminiature Connector according to German DIN 41 652. The connector 26 protrudes with its female connector from the front opening 24 down from. Its rear connection side can, what is not shown in the drawing, electrically to be connected to cables from the outside via others Housing openings introduced into the interior of the housing 10 are. Such an opening can for example in Area of the rear 28 of the housing 10, and there in the lower part 12 of the same, be left out.

The housing 10 is with its connector 26 on one Mated connector 30, which in turn in a Front plate 32 is fastened by two screws 34, 36. The Mating connector 30 pierces one in the front panel 32 recessed section 35 (Fig. 2). With its wraparound The mating connector 30 sits in a flange 38 the cutout 35 on the rear side 42 of the front plate 32 surrounding recess 40. From the rear 42 of the front panel 32 protrudes according to FIGS. 1 and 2 of the mating connector 30 with its connection side 44 downwards. Of the The mating connector protrudes from the front 45 of the front plate 32 30 with its pin header 48. The single ones Pins 50 of pin header 48, one of which is shown 3 nine are shown, engage in the assembled State according to FIGS. 1 and 2 in a corresponding number Bushings of the female connector of the connector 26. This type the plugging together of two connectors is known.

In the front panel 32 are an extension of the cover part 14 and in the present example also the bottom part 18 of a housing 10 to be connected in the present example there are five holes 54 and 56 respectively. A pin 58 can be inserted into each of these bores 54 his end 60 shaped neck are firmly inserted. In the situation shown in Figures 1 to 3 a pin 58 is inserted into the middle hole A3. On the other longitudinal side of the connector 30 is a pin 58.1 inserted in hole B3. Pins 58 and 58.1 are opposite each other with respect to the mating connector 30. A maximum of five of the pins 58 or 58.1 can in the area of a connector in the front panel 32 in Area of a cutout 35 are used.

The neck 60 of each pin 58 has a longitudinal area a cross-sectional broadening, such as one bead-like thickening 62. bead-like thickening 62 holds the pin 58 sufficiently firmly in a neck 60 adapted bore 54 or 56.

On the housing 10 are the number of holes 54 and 56 corresponding number of tongues 66 available. This Tongues 66 protrude from the cover part 14 from the front opening 24 of the housing 10. Collar in a similar way Tongues 68 as an extension of the bottom part 18 also from the front opening 24 to - in the drawing - from below. in the Connection area of each tongue 66, 68 with the actual one Lid part 14 or bottom part 18 is both in each tongue 66 and in each tongue 68 a material weakening 70 molded so that each tongue 66, 68 easily broken off from the cover part 14 or bottom part 18 and can be removed with it.

In the plug-in configuration according to FIGS. 1 to 3 the tongue 66.3 (Fig. 5), which is in the region of the bore A3 (Fig. 3), canceled and therefore not available. At the The position of the tongue 66.3 is in the plugged together State of the two connectors 26, 30 of the pin 58. In the tongue 68.3, which is located in the Area of hole B3 would be located, canceled and thus unavailable. The pin 58.1 is in its place (Figs. 1, 2 and 3). At the locations of holes A1, A2, A4 and A5 are tongues 66.1, 66.2, 66.4 and 66.5. Correspondingly, these tongues are opposite four tongues 68.1, 68.2, 68.4, 68.5 are also available. Only at Remove the middle tongue 66.3, 68.3 on each Long side of the housing 10, the housing 10 can with the the front plate 32 equipped with the two pins 58, 58.1 can be scheduled. Depending on the existing one Tongues 66, 68 on the one hand and the correspondingly arranged Pins 58, 58.1, on the other hand, are different configuration options and thus coding positions possible. Of course, another can be used in the A-holes Number of pins 58 as inserted in the B holes his.

In the mating connector 30.2 shown in Fig. 3.2 are also only five A holes and five B holes present, although it is screwed to the front panel 32 Mating connector 30.2 not one 9-pin, but for example a 25- or 37-pin Counter-connector acts. The A holes respectively the B holes begin in the present example always in the area of the left screw connection 34.

What applies to the front panel 32 also applies to the housing 10. So even with larger housings that are suitable for 25-, 37- or, for example, 50-pin connectors are designed, also only the number of A-holes and B-holes corresponding five tongues 66 and 68 available (Fig.5.1). These individual tongues also start at the example left side of the cover part 14.1.

4 there are two parallel rows A-holes 54.4, 54.5 and two parallel rows of B-holes 56.4, 56.5 available. In two side by side Holes 54.4, 54.5 and 56.4, 56.5 a wall part 72 having two necks 60.1, 60.2 can be used become. The wall part 72 is in the inserted state aligned transversely to the longitudinal orientation 1. Transferred to the 1 could therefore be a wall part 72 instead of the pin 58 to be available. Since the wall part 72 transversely to the tongues 66 or 68 is aligned, it cannot happen that in the case of a coding not to each other matching connector - incorrectly - tongues 66, 68 and wall parts 72 pushed flat against each other could become.

While the pins 58 or the wall parts 72 on the front 45 of the front panel 32 are attached, is in the representation according to Figures 6 to 7 an approximately U-shaped Holding part 80 available, that in the present example on the back 42 of the front panel 32 in the Well 40 is screwed. The screw connection takes place the screw connections 34, 36 of the respective mating connector 30 on the front plate 32. For this purpose, the holding part 80 two adapted to the locations of the two screw connections 34, 36 Drill holes 74, 76 are available. Additional screw connections are therefore not to be provided in the front plate 32.

The web 82 of the holding part 80 is frame-shaped and frames a central cutout 83. From the web 82 project end flanges approximately at right angles. These flanges form counterparts 84, 86 and are functionally comparable the pins 58 or the wall parts 72. In the connection area the counter tongue on the web 82 is a material weakening 70 is present so that the countermeasures 84, 86 can be easily and completely broken off from the web 82. The counter tongues 84, 86 protrude through the one in the front plate 32 existing cutout 35 through. They are each at the point where the A-holes 54 and B holes 56 (Fig. 3) are located. That in Fig. 1 Housing 10 shown, in which the tongue at A3 66.3 and in the same way at point B3 the tongue 68.3 is missing, can also on the front panel shown in Fig. 6 32 can be attached with their holding part 80. While at 1, pins 58 and 58.1 are present are in the illustration according to FIG. 6 on the Instead of these pins there are countermeasures 84.3 and 86.3.

7 shows a partial side view of the holding part 80 and shows the outside of the at locations A1, A2, A3 (partially) existing countermeasures 84.1, 84.2 (84.3). On digits B3 (partially), B4, B5 are the inside Tongues 86.3 (partially), 86.4 and 86.5.

To install on the plate 32 shown in FIGS. 6 and 7 must therefore of the holding part 80 the middle of the five A-tongues 84.3 and the middle of the B-tongues 86.3 are broken off.

The holding part 80.2 shown in Fig. 7.2 is longer than the holding part 80 and is for example for the connector 30.2 of Fig. 3.2 provided. This holding part too 80.2 has the same in the present example Number of counter tongues 84, 86 like the holding part 80 and also again two drill holes 74, 76.2 for screwing on the Holding part 80.2 to a front panel 32.

8 and 9 differ from 6 to 7 in that the the holding part 90 comparable to the holding part 80 (FIG. 9.1) is not planar countermeasures, but with a turn 98 provided counter-tongues 94 and 96 respectively. The Turns 98 of the two opposites 94, 96 are present Case facing each other. If on one Housing 10 does not have the "correct" tongue 66 or 68 has broken off, the housing 10 can not on one with the Holding plate 90 provided front panel 32 are plugged in; the "wrong" tongue 66, 68 would not be at the bend 98 of the respective tongue 94.1 to 94.5 or 96.1 to 96.5 can slide past due to the existing wrong tongue 66, 68 turning across the way 98th

The holding parts 80, 90 with their opposites 84, 86, 94, 96 and pins 58 and wall portions 72 are also preferred made of sheet steel or aluminum material.
