WAYS OF CARRYING OUT THE INVENTION

For the construction of electronic components worldwide the so-called 19 inch system enforced. In individual This 19 inch system is the basis of appropriate countries Norms. So applies to that shown in Fig. 1 Subrack 10 in Germany DIN 41 494. The subrack 10 can be in control cabinets or other Switchgears are installed, which are in accordance with DIN 41 488 be standardized.

At the end face 10 are different in the subrack large inserts 12 used. Not from inserts 12 occupied spaces in the subrack 10 covered by front panels 14. The slots 12 are also covered by DIN 41 494.

The subrack 10 has a height H2, which in the present Example corresponds to the standardized 3U grid dimension. The front panel attached to the front of the insert 12 16 has a height H1, which is slightly smaller than the height H2. The width of this front panel 16 is slightly smaller than the standardized grid width B1, the is 4TE in the present case.

One or more are within the slot 12 Printed circuit boards 154 (Fig. 3) inserted. The front is on one PCB 154 a connector 18 attached by DIN 41 612 is standardized. The connector 18 is in its clearance profile is smaller than the footprint of the Front panel 16. Therefore, the front panel 16 frames the same within the grid dimension H1 x B1. If the front panel is missing 16 are air clearances around the connector 18 available.

A connector 20 can be placed on the connector 18 plug in, which is available in a housing 22 (Fig.1,2). The plug connector 20 can be led out of the housing 22 Cable 24 (Fig. 1) electrically to other electrical Connected to consumers.

A plug connector 18 is usually located in the insert 12 placed as a so-called knife bar, while in the housing 22 the "female" counterpart, a Connector 20 is placed as a so-called female connector.

Several openings 28 are present in the housing 22, as is still the case is described in more detail below. In one of the openings 28, the cable 24 is formed by a crimp flange Insert held on housing 22 as below is described in more detail. Other case openings that not required in the configuration shown in FIG. 1 are by insert pieces designed as blind plugs locked. The formation of the housing openings 28 with the different inserts is shown below described in more detail.

The housing 22 is designed to be immune to interference radiation. It's over made of metallic material. Of this housing 22 is 2 shows its trough-like bottom part 25, the by a contour corresponding to the bottom 29 of the bottom part 25, Lid part not shown in the drawing is closed. In the between the bottom part 25 and the cover part located cavity, the interior 26, is space for the connector 20 and its line connection technology to the cable 24 leading out of the housing 22.

In the housing 22 are to lead out one or more Cables 24 different openings 28 in the bottom part 25 framing side wall 30 available.

The housing 22 can be screwed onto the insert 12. This allows a permanent contact between the Ensure connector 20 and mating connector 18. The respective screw connections are in - Fig. 2 upper and lower - front end portion 32, 34th the housing opening 36 surrounding the connector 20. In a screw 38 is seated in the two end regions 32, 34 can each be screwed into a nut piece 40. These two nut pieces 40 sit in an upper and lower rail support 42, 44 on the subrack 10 are attached. The housing 22 can thereby Screw the press fit onto the subrack 10.

The housing 22 sits with its upper end region in FIG. 2 32 directly on the upper rail support 42. It there is direct contact between the housing 22 and the rail support 42. The other end portion 34 of the Housing 22 is in direct contact with a front plate 16 shown in the drawing. The front panel 16 in turn has direct contact with the one behind her Rail support 44 (Fig. 2). 2 is both the state shown that the housing 22 immediately, at missing front panel, screwed onto the rack 10 is, as well as the state that the housing 22 on an existing front panel 16 seated on the rack 10 is screwed.

Regardless of whether a front panel 16 is on the insert 12 is present or not, the connector 20 in his assembled with the mating connector 18 Condition always the same orientation and distance to the Have slot 12. This means that if one Front plate 16 is present, the connector 20 continues protrudes from the opening 36 than when there is no front panel 16 is the case. If there is no front panel 16 the connector 20 is sunk deeper in the housing 22 present than it is in the presence of a front panel 16 is the case. The two states are in Fig. 2, like already executed, shown schematically. If there is no Front plate 16 protrudes from connector 20 by dimension 46 the housing 22 out. If the front panel 16 is present, it protrudes the same connector 20 by the measure 48 from the housing 22 out. The dimension 48 is about the thickness 50 of the front panel 16 larger than measure 46.

The different positioning of the connector 20 in the housing 22 by different spacers 52, 54, 56 enables.

In a first type of connector 20, which is shown in FIG and is shown schematically in Figures 4.2, 4.3 and which corresponds to type E according to DIN 41 612, come in the two end regions 32, 34 of the housing 22 spacers 52 and 52.2 are used, which are mirror images of one another, as Figs. 4.2, 4.3 illustrate. The spacers 52 and 52.2 can be used in each end area 32, 34. Your different installation depends on whether one Front plate 16 in the area of the mating connector 18 on Insert 12 is present or not.

In the upper half of the housing of Fig. 2 is the connector 20 installed extremely deep into the housing 22. The Spacer 52 is therefore present in the end region 32 that its longer angular wall 58 faces the opening 36 and out Direction of the opening 36 on the projecting shoulder 62 of the Connector 20 is present (Fig. 2, 4.2). In the other, Corner area 34, not shown in the drawing, would be at this arrangement of the connector 20 the mirror image Spacer 52.2 installed, its longer angled wall 58 also from the direction of the opening 36 - and thus in Fig. 2 from the left - abuts the connector 20.

If the front plate 16 is present, the plug connector 20 projects extremely little into the housing 22. In the lower end area 34 the spacer 52 is then positioned there, as can be seen in the lower half of the drawing of FIG. 2 becomes. In the other, in FIG. 2, the upper end area 32 would be in this arrangement of the connector 20 the mirror image Spacer 52.2 installed. The longer one Angular wall 58 of both spacers 52, 52.2 is in each case the right side 60 of the shoulder 62 of the connector 20th on. The thickness 64 of the longer angular wall 58 represents the measure to which the connector 20 in different degrees the housing 22 can be positioned and corresponds to the 50 thickness of the front panel 16.

In the present example there is a shorter angled wall 59 of the spacer 52, which is perpendicular to the longer angular wall 58 is aligned, flat on the floor 29 of the Bottom part 25. By arranging the shorter angled wall 59 between the shoulder 62 of the connector 20 and the Bottom 29 of the bottom part 25, the connector 20 in the prescribed orientation within the housing 22, and what the distance perpendicular to the bottom 29 of the bottom part 25 concerns, held.

The built-in spacers 52, 52.2 are together with the connector 20 by the screwed onto the bottom part 25 Lid part prevented from falling out.

Another type of connector 20 is shown in Figs. 4.4 and 4.5 indicated with the reference number 20.2. This connector corresponds to type F according to DIN 41 612. So too this connector inserted into the (same) housing 22 can be, also in two different Positions depending on whether there is a front panel or not, there are two different spacers 54, 56 required. These two spacers 54, 56 are not the same and not mirror-like. If there is none Front plate (Fig. 4.4) comes the spacer 54 and in the other Case, with the front panel 16, the spacer 56th (Fig. 4.5). Both spacers 54, 56 are each U-shaped and extend from one End area 32 to the other end area 34. In the area between the two end regions 32, 34, both have spacers 54, 56 the same rectangular cross section 66. With the The area of this rectangular cross-section 66 is that in question Spacer 54, 56 on the cover part of the housing 22.

The one at the two ends of the rectangular cross-sectional area 66 body part adjoining at right angles 68 or 72, the 54 with the spacer inserted and 56 in both end regions 32, 34, respectively is present, the spacer 54 has a console-like Projection 70 on the shoulder 62.2 of the connector 20.2 bears from the direction of the opening 36 (Fig. 4.5). In the presence of a front panel 16, the spacer 56 needed, the end of the rectangular cross-section 66 each subsequent body part 72 two console-like Has protrusions 74, 76. The distance 78 between the two projections 74, 76 corresponds to the height of the shoulder 62.2 from connector 20.2.

The projections 70 and 74, 76 of the spacer 54 and 56 are each separated by a transverse wall 80 limited. When installed, the spacers 54 are seated or 56 with this transverse wall 80 perpendicular to the Bottom 29 of the bottom part 25 in undercuts 82 of the in the end regions 32, 34 thickened regions of the side wall 30 of the bottom part 25. Sits in these undercuts 82 also the spacer 52 with its two angular walls 58, 59 connecting transverse wall 80 (Fig. 2, 4.3 and 4.4).

To the outside is in addition to those present in the housing Spacers 52 or 54 or 56 respectively a trench-like depression in the end regions 32, 34 of the Bottom part 25 available. In these trench-like depressions can optionally a coding device 84 or 86 can be installed.

In terms of components, the coding device 84 corresponds to the coding device 86. Each coding device 84, 86 has parts, which are to be inserted into the bottom part 25 and parts which are in the Insert 12 are to be fastened.

The parts of the coding device located in the base part 25 84, 86 consist of a coding bushing 88 (FIG. 6), which are inserted into a coding part 90 (FIG. 8) from above becomes. The coding bushing 88 has a lower region 92 with a hollow, circular cylindrical shape. In area 92 a slot 94 is formed from below. The area 92 will in Fig. 6 from above by a hexagonal plate in plan 96 covered, which has a central opening 98. Of the Diameter 100 of opening 98 corresponds to the inside diameter of area 92.

The coding part 90 has an area 102, which by central Longitudinal cutting of a cylinder with a hexagonal Base area has arisen. The area 102 therefore has a coat of a half cut in the longitudinal direction Cylinder with a hexagonal cross section. The inside diameter 104 of area 102 corresponds to the outer diameter 105 from the coding socket 88.

The area 102 is delimited at the top by two in cross-section the outline of the plate 96 of the coding bushing 88 and hexagonal corresponding to the outer contour of the area 102 Bodies 106, 108. These spaced apart bodies 106, 108 have an intermediate region which is circular in cross section 110 with an outer diameter 112. By the one body 106, 108 and through area 110 Longitudinal bore 114 through. The inside diameter 116 of this Longitudinal bore 114 corresponds to the outer diameter 105 of the Area 92 of the coding socket 88. This allows the coding socket 88 from the direction of the body 106 - in the drawing from above - in the longitudinal direction (longitudinal axis 118) into the coding part 90 are inserted until they with their plate 96 of rests on top of body 106. Im in the end areas 32nd or 34 inserted state grip projections 119 (FIG. 2) of the bottom part 25 between the bodies 106, 108 and nestle against the intermediate region 110 from the outside. As a result, the coding part 90 is in the direction of its longitudinal axis 118 held securely in the bottom part 25. After unscrewing the lid part on the bottom part 25 can Coding part 90 also does not fall out of the bottom part 25.

In the bottom part 25, the coding part 90 can be used in different ways Rotary alignments are used. In the present case are the body corresponding to the hexagonal base 102, 106, 108 and plate 96 six different orientations possible. In addition, the coding socket 88 in six different rotational orientations in the coding part 90 sit in. The slot 94 of the coding socket 88 can therefore six different rotational orientations relative to the Have coding part 90.

In the slot 12 are a coding pin shown in Fig. 7 120 and a further coding part shown in FIG. 9 122 attached. The coding pin 120 has a cross section circular rod part 124, the outer diameter 126 corresponds to the inner diameter 100 of the coding bushing 88. A longitudinal rib 128 is formed on the rod part 124 cross-sectionally the slot 94 of the coding bushing 88 in this way is adapted that the rod member 124 with its longitudinal rib 128th are inserted into the area 92 of the coding socket 88 can and then with its longitudinal rib 128 in the slot 94 sits. The rotational orientation of the rod part 124 therefore depends from the rotational orientation of the coding socket 88, since only then the coding pin 120 are inserted into the coding socket 88 can, if the longitudinal rib dip into the slot 94 can.

In the lower area of the rod part 124 is a thickened one circular cylindrical region 130 present. Its outside diameter 131 corresponds to the inner diameter 104 of the coding part 122. The coding part 122 corresponds to the coding part 90; is only formed symmetrically to the coding part 90. When the two coding parts 122, 90 are placed next to one another put their two areas 102 together.

The coding pin 120 is with its rod part 124 in the Coding part 122 from - in the drawing - inserted below. The rod part 124 of the coding pin 120 can then in the Immerse the coding socket 88, which in turn is in the coding part 90 sits. This joining together of the four parts is only possible if the coding part 122 shown in FIG. 9 Positioned "to match" the coding part 90 shown in FIG. 8 is. The two areas 102 of the two coding parts 90, 122 must - as shown in the drawing - to each other be aligned in parallel. In addition, the coding pin 120, in different rotary orientations in the coding part 122 can sit, aligned so that his Longitudinal rib 128 is aligned with slot 94 of coding sleeve 88, as stated above.

The coding pin 120 and the coding part 122 sit in one Holder, of which the half holding jaw 140 shown in Fig. 10 is. Formations are in this holding jaw 140 142, the cross-sectional shape of the body 106, 108 and the Intermediate area 110 of the coding part 122 and the base plate 148, the circular cylindrical region 130 of the Coding pin 120 completes below, correspond. The base plate 148 of the coding pin 120 corresponds in plan the plate 96 of the coding socket 88 and corresponds to the base of the body 106 from the coding part 122 or 90. The lowest shape 142.1 of the holding jaw 140 or 140.2 (FIG. 3) therefore has a height 150 that from the heights 150.1 of the base plate 148 from the coding pin 120 and the height 150.2 of the plate 106 from the coding part 122 put together. The shape above the shape 142.1 142.2 is the circular contour of the intermediate region 110 of the coding part 122 adapted.

Between two holding jaws 140, 140.2 (Fig. 3), which is what the Forming 142 concerns, are identical, lets a coding part 122 with a coding pin seated in it Fix 120 in position. The two holding jaws 140, 140.2 are by means of a screw 151 (screw axis 152) a hole 153 in the two holding jaws 140, 140.2 on a circuit board 154 seated in the insert 12 screwed on.

Those consisting of the coding pin 120 and the coding part 122 Coding parts are attached to the circuit board 154 so that they are in the direction of those in the housing 22 Coding parts are aligned. When attaching the in the housing 22 located connector 20 to the on the circuit board 154 attached mating connector 18 dip the 12 coding parts protruding from the slot (coding pin 120, coding part 122) in the housing 22 Coding parts (coding bushing 88, coding part 90) into it. This State is shown in Fig. 2.

In the two end regions 32, 34, the coding devices 84, 86 located there can be "set" differently. Taking into account the hexagonal outline shape of the different coding parts 1296 (= 6 ⁴ ), this results in different coding positions.

If no coding of the housing 22 is desired, can the coding devices 84, 86 can also be omitted. This has no qualitative for the RF tightness of the housing 22 Disadvantages, since the coding device inside the thickened End regions 32, 34 of the bottom part 25 and the corresponding thickened areas of the not shown in the drawing Lid of the lid part are present. The coding devices are thus within that occupied by the housing 22 Clearance profile. Outwardly there are no in louvers protruding into the interior of the housing 22 coding devices should be present or not to be available.

The provided in the housing 22 - in the present example eight - openings 28 (Fig. 2) for insertion of a or more cables 24 are in the present example all trained equally. In each of these openings 28 can Insert pieces designed as blind plugs or crimp flanges be used. The following are different such inserts shown in more detail.

Each of the insert pieces used has in the housing 22 220, 226 (Fig. 12, 11) with the side adjacent side wall 30 of the bottom part 25 a multi-stage Toothing 236 (Fig. 11, 12 ff.). The multi-stage Toothing 236, which is described in more detail below and shown in different variations a longer and thus larger area compared to the prior art as well as a contact surface with more kinks between insert and side wall. The electrical Resistance between the insert and the side wall is accordingly small. In addition, the meandering, multi-stage toothing an improved Protection against penetrating splash water.

11 shows an insert designed as a crimp flange 226 shown. It has a continuous opening 250 with longitudinal axis 252. This longitudinal axis 252 coincides with the Longitudinal axis of a cable 24 inserted into the housing 22 together. A sleeve 254 is inserted in the insert piece 226, which by means of two circumferentially spaced apart Collar 256, 258 in the longitudinal direction of the longitudinal axis 252 tensile, pressure resistant and therefore non-shifting as well as is still seated against rotation in the insert 226. The The cross section of sleeve 254 is designed to match cable 24. The cable sheath and, if necessary, a screen braid lie tightly on the sleeve 254 in the assembled state while the wires of the cable pass through the sleeve 254 become. Another is not on the cable jacket shown sleeve pushed and squeezed onto the jacket. This allows the sheath to be fixed on the sleeve 254 be attached. This attachment of a cable to the Sleeve 254 is known.

The insert 226 (FIG. 11) has in the present case a cuboid body 260 with a continuous opening 250. From this body 260 collar on its two opposite Sidewalls 262, 264 each have two protrusions 266, 268. The two side walls 262, 264 meet in the built-in Condition on the side wall 30 of the housing 22.

The two protrude in the direction perpendicular to the longitudinal axis 252 Projections 266, 268 by the length L from the side wall 262 or 264.

Each protrusion 266, 268 has from the side wall 262, 264 cantilevered and on the body or on the side walls 262, 264 abutting side surfaces 270, 272. Die a side surface 270 is less than 90 degrees Angle 274 aligned with the side wall 262, 264. Your length LS projecting from the side wall 262, 264 is thus longer than the corresponding overhanging length L of the others Side surface 272, which is at a right angle 276 from the Sidewall 262 or 264 protrudes. The cantilever total length of both side surfaces 270, 272 of both Projections 266 (or 268) is 2 LS + 2 L and is therefore larger than 2 L.

A longitudinal rib 280 is formed on each side surface 270. When inserting insert 226 into an opening 28 rubs the longitudinal rib 280 on the abutting surface respectively Side wall contact area. This makes a dense System or a continuous contact between Insert piece and side wall given. The tabs 266, 268 with the longitudinal ribs 280 are formed so that the insert 226 with a press fit from "above" to that of Lid part exempted bottom part 25 can be used. In the side wall 30 are corresponding indentations and projections, the protrusions 266, 268 and their mutual Arrangement are adjusted accordingly. The insert 226 then sits with a press fit in the side wall 30.

In addition to the insert 226, which in the area of one in the Electrical cable 24 to be inserted into housing 22 are the neighboring ones in the present example Housing openings closed by insert 220 (Fig. 12). This insert piece 220 provides a blind plug represents, as already stated. The insert 220 has the same protrusions 266, 268 and longitudinal ribs 280 like the insert 226 and sits with an appropriate press fit in the side wall 30. Its opening 282 is on one Side closed at the end by a wall 284. Thereby the insert 220 forms a closure for the concerned Opening in the side wall 30. The inserts 220, 226 can optionally in the openings 28 of the housing 22nd be used.

The housing 22.2 shown in detail in FIG. 13 differs from the housing 22 by a slightly different one Teeth 236.2 of the inserts sitting in the housing 22.2 220.2 or 22.2 in the housing insert 226.2 insertable (Fig. 14). Even the gearing 236.2 and thus also the insert 226.2 two laterally projecting projections 266.2 and 268.2. In contrast to insert 226, the Insert 226.2 and thus the teeth 236.2 Side surface 270.2 in the same way as the opposite one Side surface 272 perpendicular to the side wall 262 or 264 of the cuboid body 260 aligned. The projecting length L of the two projections 266.2 and 268.2 thus corresponds to the cantilever length LS of each side surface 270.2 or 272. For the insert 226.2 and its projections 266.2 and 268.2 is the total collar length of the two Projections 266.2 and 268.2 the value 4 LS. This Value corresponds to the value 4 L.

The housing 22.3 shown in Fig. 15 corresponds to the above described housings with the difference one different toothing 236.3 between the respective insert 220.3, 226.3 and the relevant side wall 30. From the cuboid body 260 of the insert 226.3 (Fig. 16) each laterally has a single cross section dovetail-shaped projection 266.3, 268.3. The opposite side surfaces 270.3, 272.3 are present at an angle to the longitudinal axis 252. Your length is LS thus greater than the projecting length L of the relevant Projection 266.3 or 268.3. It applies to everyone Advantage that the two lengths LS are greater than both Lengths L.

A toothing 236.4 is provided in the housing 22.4 (FIG. 17) present, which consists of a rectangular in plan Projection 266.2 (268.2) and a triangular projection 266.4 (268.4). The side facing each other Side surfaces 270.2 and 272 at the projection 266.2 as well as 270.2 and 270.4 at the projection 266.4 are partial rectangular (side surface 270.2, 272) respectively sloping (side surface 270.4) on insert 226.4 or the formed as a blind plug 220.4 insert. The total length of all overhanging side surfaces the projections on one side of the cuboid body is 3 L + LS and is therefore larger than 2 L.

Also with the teeth 236.5 (Fig. 19) of the housing 22.5 is between the insert 220.5 or 226.5 and the relevant side wall 30 of this housing the summed up Cantilever length is the same as for the teeth 236.4 according to FIGS. 17 and 18. The only difference is in that between the inclined side surface 270.4 of the Projection 266.4 and the neighboring one, at 90 degrees to Longitudinal axis 252 aligned side surface 272 of the adjacent Projection 266.2 a extending in the longitudinal direction Side surface 273 is present.

The toothing 236.6 shown in FIGS. 21, 22 between an insert 220.6 or 226.6 and the relevant side wall 30 of a housing 22.6 has this protruding total cantilever lengths or side wall lengths from 3 L + LS up. In contrast to the gearing 236.4 (Fig. 17, 18) is triangular in cross section Projection 266.4 with its upper one in the drawing Side surface 270.2 is flush with the outer surface of the cuboid Body 260, while this with the toothing 236.4 (Fig. 17, 18) is not the case. The projection there has 266.4 a recess 290 to the corresponding outer wall of the cuboid body 260.

The teeth 236.7 in the housing 22.7 or the Insert pieces 220.7 and 226.7 which can be inserted into this housing (Fig. 23, 24) has two projections 266.2, 268.2, as they also exist with the teeth 236.2 (Fig. 13, 14) are. The upper projection 266.2 in the drawing, respectively 268.2 of the toothing 236.7 is flush with the Outer wall of cuboid body 260, similar to this also the case with the teeth 236.6 (Fig. 21, 22) is. In contrast, the toothing 236.2 according to 13, 14 a recess formed by a side wall 262 between the projection 266.2 and the outer wall of the cuboid body 260 present. With the gearing 236.7 is an accumulated length of the protrusions as in the Teeth 236.2 available in the following way: 4 L = 4 LS.

The teeth 236.8 of the housing 22.8 shown in FIGS. 25 and 26 have a hammer head design on the relevant insert 220.8 or 226.8. The projection 266.8, 268.8 on each of the opposite sides of the parallelepiped-shaped body 260 has an upper and lower side surface formation in the drawing, so that each projection 266.8, 268.8 has a two-stage toothing. Each toothing is formed from a step-shaped side surface 273, the length of which protrudes through the angled portion L / 2 + T + L / 2 . Both step-shaped side walls 273 thus have a total length of 2 L + 2 T. This dimension is greater than 2 L.

The teeth 236.9 of the housing shown in FIGS. 27, 28 22.9 is formed like a truncated pyramid. One and only Projection 266.9, 268.9 of insert 226.9 has opposite, aligned obliquely to the longitudinal axis 252 Side surfaces 270.9 with a respective length LS. The summed up Lengths of the cantilevered side surfaces of a projection thus have the length dimension 2 LS. That measure is greater than the value 2 L. For the inserts 220.9, which in the side walls 30 as blind plugs, the same applies accordingly. Incidentally, this applies comparatively to everyone protruding inserts 220. The teeth shown apply in the same way to the corresponding ones Blind plug.

Various types of insert pieces can be present in one housing be. This affects the type of insert. So the insert can be used as a blind plug or as Fit the crimp flange in the housing and accordingly either to close an opening 28 or to pass through of a cable can be used through an opening 28. In one housing you can also insert different items Gears are used. This then requires but correspondingly different gears in the Housing wall 30.

On the right-angled to the toothed walls of the cuboid Body 260 existing two other outsides the insert pieces 226, 220 are each a cantilever Cross rib 298 present. The cross rib 298 is in the present Case not only on the outside visible in the figures 296, but also on the opposite Outside of the cuboid body 260 present. This Cross ribs meet the bottom 29 on the one hand from the bottom part 25 and on the other hand from the inside not in the drawing illustrated cover part, from above on the bottom part 25 and thus also on the inserts 220 or 226 fits tightly. The inserts 220, 226 respectively the ones shown above, differentiated by each This means that insert pieces that differentiate teeth have not just intimate contact through their through the respective toothing and the longitudinal ribs 280 brought about an interference fit with the walls 30, but also a splash-proof System on the other walls adjacent to the inserts, namely the bottom 29 and the cover part. The housing 22 is all around close to the outer surfaces of the insert 220 and 226 respectively.

To identify the respective housing 22 are on the bottom 29 of the bottom part 25 a logo 160 and one Type designation 162 by corresponding positive or negative Formation of the floor made plastically visible. Comparable Labels can also be on the cover part be provided.

The housing 22.2 shown in FIG. 29 largely corresponds the housing 22 described above Cross section of the housing 22.2 the same size as the cross section of the housing 22, so that the housing dimensions of a 3U x 4HP front panel of the already mentioned 19th Customs system.

Compared to the housing 22 are larger in the housing 22.2 Openings 28.2 are available so that they are large and / or several cables at the same time through a corresponding opening 28.2 in or out of the housing 22.2 can be. This allows multiple cables to be tight side by side with the same cable clamp in the housing 22.2 are brought in or out.

29 is in the housing 22.2, as with Housing 22, the connector already mentioned above 20 placed. Its counterpart, connector 18, is as already stated above, arranged in the slot 12 (Fig. 1). For the rest, the following applies to the training Housing openings 28.2 above the openings 28th already executed.

The housing 22.2 is also designed to be interference-free and made of metallic material. By means of the present In the case of two screws 38, the housing 22.2 can be screw the insert 12, as for the above Housing 22 has already been described. Depending on whether at the slot 12 a front panel 16 is present or not, sits the housing 22.2 differently close to the slot 12. Nevertheless also applies to housing 22.2, as well as to housing 22, that the connector 20 present in the housing 22.2, independently whether there is a front panel on the slot 12 is or not, with its mating connector 18 in the composite Condition always the same orientation and distance to insert 12. This different Positioning is carried out as in connection with the housing 22 already mentioned, by different spacers 52.4, 52.6, 54.2 and 56.2.

In a first type of connector 20 shown in FIG. 29 is shown schematically and according to type E According to DIN 41 612, come in the two end areas 32.2, 34.2 of the housing 22.2 spacers 52.4 and 52.6 for Commitment. If there is no front panel, sit in the Housing 22.2 in the left and right end areas 32.2, 34.2 each a spacer 52.4 (Fig. 30, 32). If there is one Front panel, which state in the right half of Fig. 29 is shown, sits in the left and right end 32.2, 34.2 each the spacer 52.6 (Fig.30,33). The spacer 52.4 has an angular shape. Its longer Leg 310 is rectangular in cross section. On his 32 lower side is a narrower, in cross section approximately rectangular bar 312 available. The shorter one Leg 314 is rectangular in cross section and ends in a central cuboid 316. The spacer 52.6 is made from the body of the spacer 52.4, in addition to the cuboid piece 316 is parallel to the longer leg 310 running, in comparison cross section smaller square bar 318 is integrally formed.

In the case of the one mentioned in connection with FIGS. 4.4 and 4.5 other type 20.2 of connectors 20 come in 34 and 35 shown spacers 54.2 and 56.2 used to the connector 20.2 in the same To position on the mating connector 18 independently whether there is a front panel 16 on the housing 22.2 is or not. The two spacers 54.2 and 56.2 differ from the spacers mentioned above 52.4 and 52.6 first of all in that, like which is the case with the spacers 54 and 56, U-shaped are trained. Those in the left and right end area 32.2, 34.2 Existing spacer sections are with this another type of connector 20.2 through a connecting part 320 interconnected, which is a rectangular cross section 66 owns. With the spacer 54.2 are Both body parts present at the end on the connecting part 320 322, 322.2 mirror images of each other, otherwise in Cross section formed the same. The two body parts 322, 322.2 have an approximately chair-like shape. At the spacer 56.2 are the two end-side body parts 324 thereof, 324.2 also of the same cross-section and mirror image aligned with each other. The "seat" 326 at Body 322 or 322.2 and the U-shaped indentation 328 at Body parts 324 and 324.2 enable a corresponding one Connector 20.2 different in height relative to Connecting part 320 of the respective spacer in the Housing 22.2 can be placed. The different height alignment of the connector 20.2 is taken into account the presence or absence of one Front panel 16.

To the outside, as with the housing 22, is also in the Housing 22.2 in addition to the spacers present in it 52.4, 52.6 or 54.2 or 56.2 respectively a trench-like depression 330, 332 is present. These recesses Cross sections 330, 332 are larger than that corresponding recesses in the housing 22. In the recesses 330, 332 can be used in the present example not only a coding part 90.2 (Fig. 37) but also an the circuit board 154 (Fig. 31) attached handle 340 or Insert 342. The depressions 330, 332 are therefore larger in cross-section than the corresponding depressions for the housing 22.

At the upper end of the depression 330 in FIG 332 is a coding part 90.2. This coding part 90.2 corresponds to the coding part 90 shown in FIG concerns its external dimensions. The coding part is missing 90.2 the longitudinal bore 114 present in the coding part 90. As a result, the area 102.2 of the coding part 90.2 (FIG. 37) that formed in the coding part 90 as a result of the longitudinal bore 114 trough-shaped arching. Because of the hexagonal Cross-sectional shape of the end body 106 of the coding part 90.2 can the coding part 90.2 in six different positions can be placed in the recess 330 or 332. The coding part 90.2 does not touch the side of it bordering wall areas in the respective end area 32.2 or 34.2. Between coding part 90.2 and the wall areas the housing 22.2 is namely space for the wall 336 of the handle 340 or 342. Each handle 340, 342 has a blind hole opening that has the cross-sectional shape of the body 106 of the coding part 90.2 corresponds. Also on the handle 340, 342, a coding part 90.2 in six different Layers are used. The handle 340, 342 is formed in two parts to ensure a firm hold of the in to enable him used coding part 90.2.

As FIGS. 29, 30 illustrate, the handle 340, 342 inserted from below into the respective recess 330, 332 become. The one in the recess 330, 332 each sitting Coding part 90.2 slides partially onto the in the counter-coding part 90.2 located in the handle 340, 342. At mutual "equal" alignment of the two coding parts 90.2 on the one hand in the housing 22.2 and on the other hand in the handle 340 and 342 ensure that only that correct housing 22.2 on the relevant circuit board 154 can be applied.

The handle 340 and also the handle 342 have an after molded shoulder 344, 346 on the outside State of the two connectors 20 and 20.2 of the housing 22.2 and the mating connector 18 of the circuit board 154 shoulder 344 and 346 in also disappear of the recess 330 or 332. After loosening the Screws 38 and then removing the housing 22.2 The two handles 340, 342 lie from the printed circuit board 154 free. The two handles 340, 342 can then go outwards be pivoted, which is indicated in Fig. 36. Shoulders 344, 346 press from the outside or from above on the board 154 surrounding with the insert 12 connected areas, such as one Front panel 16.

36, a front panel 16 is indicated by dash-dotted lines, on the respective shoulder 344 from above 346 of the left or right handle 340, 342 is present. The two handles 340, 342 are pulled through drawn. By swiveling the two handles outwards 340, 342 on the handles via the axes of rotation 338 attached holder 350, 352 of the circuit board 154 upwards emotional. By swiveling the two handles outwards So the circuit board 154 from the slot 12 something - in present case by about 3 mm (millimeters) - pulled out become. This allows the 12 existing contact can be resolved.
