Description

TECHNICAL AREA

The invention relates to a housing for standardized according to DIN 41 612 plug connector for pluggable connection to mating connectors, which are available in electronic inserts according to the 19-inch system. These bays can be used in subracks according to this 19 inch system. The 19-inch system has become internationally accepted for electronic devices. The connectors suitable for this 19 inch system comply with German DIN 41 612.

STATE OF THE ART

There are connector housing of the aforementioned type are known, in accordance with DIN 41 612 standard connectors can be used. The housings are made of plastic and have at least one opening that can be closed by a plastic part, through which, in the opened state, a cable to be connected to the plug connector can be guided into the housing. The plastic housing can not completely cover the existing in the slot opening height. This opening is present on the front side in the slot, which can be used in a rack. In the slot sit one or more circuit boards, at the frontal end of each a mating connector can be attached, which can be contacted with the existing connector in the housing. In order to close the frontal opening in the slot in the standard pitch of, for example, 3HE x 4TE, front panels are known which provide a recess for the mating connector exhibit. A front panel for a slot with the grid width 4TE and the grid height 3HE framed more or less wide a dedicated mating connector, as this is much smaller in its outer dimensions, as it is specified by the width dimension 4TE and the height dimension 3HE. If the requirements for the electronic connection quality are not too great, can be dispensed with the front panel.

A störstrahlsicheres connector housing for receiving at least one connector is for example from the DE 296 18 550 U1 known. The interior of the housing has in this case in the housing walls surrounding the connector to several faulty areas, through which the interior of the housing is increased. In these missed areas of the circumferential collar of the connector can be inserted so that the connector can be positioned together with its collar recessed in the housing.

Generic connector housings are beyond, for example, from the US 4,755,148 , from the US 4,895,535 or from the US 4,761,145 known.

PRESENTATION OF THE INVENTION

Based on this prior art, the present invention seeks to provide an improved connector housing of the type mentioned.

This invention is given by the features of claim 1. Starting from the well-known in the art, suitable for assemblies in the 19 inch system housing, the same is characterized according to claim 1 in that the housing of the invention with its length dimension in the area of its connector receiving end face corresponds to the longitudinal extent of a front panel, with which the counter-connector receiving opening of a drawer can be closed in height. This makes it possible, just by the housing according to the invention, without additional arrangement of a front panel to close the existing opening in a slot heightwise.

The possibility of using the housing according to the invention is increased by ensuring that the same housing can be used for different types of connectors. These different types of connectors for different connectors are standardized by the German DIN 41 612 type. In the cases means for arranging profile parts are provided by which these different types of connectors can be used in the same housing.

These devices can be used at the same time to arrange the connectors differently far recessed in the housing. This is advantageous in order to take into account whether in the slot a front panel surrounds the existing there mating connector, or whether such a front panel is not available. Since the housing should lie as close as possible to the insertion opening, the housing is in the presence of a front panel further away from the drawer, as it is the case with no front panel.

Such devices, with which the connector can be arranged sunk in different amounts in the housing, are the subject of dependent claims and are indicated in the drawing for the two different types E and F according to DIN 41 612.

Advantageously, not only the length dimension but also the width dimension of the housing according to the invention in the region of the connector receiving end face is chosen so that this width corresponds to the corresponding width of the opening in the slot covering the front panel. This width dimension is preferably 4TE in the 19 inch system.

To ensure that the housing according to the invention is also attached to the correct slot and thus to the correct mating connector of a particular slot, and that thus no permutations between slots can occur, a coding device can be provided on the housing according to the invention. According to the invention, this coding device is present within the housing dimensions defined by its width and its length. In addition, this coding device is preferably placed in at least one of the two existing in the longitudinal direction of the housing end portions. Due to the enlarged in the longitudinal direction relative to the prior art housing dimension, the resulting housing space offers to provide there a coding. Such a coding device can optionally be provided in one or in both end regions. The arrangement of the coding device within the space occupied by the housing according to the invention has the advantage that it is not necessary to dispense with the optimum high-frequency tightness that is possible through the housing.

Details of encoders which correspond to the above embodiments are the subject of subclaims and are also shown in the drawing.

In order to ensure with certainty the electronic connection quality in the joint area between the housing according to the invention and the insert in which the housing is to be seated, metallic spring elements can be present at the free edge of the housing, which cover the gap between the housing and the insert or between the housing and one Bridge the front panel of the insert.

In order to ensure the Störstrahlsicherheit not only in the area of the connector but also in the area of the openings through which an electrical cable in the Inside of the housing can be introduced, may be formed metallic according to an embodiment of the invention, a cable opening closing a blind plug or a cable in a housing opening holding cable attachment. The blind plug or the cable attachment may preferably be formed as inserts, which have projections which correspond with recesses in the housing such that the insert in question along the recesses, which represent longitudinal guides for the insert, can be inserted into the housing. These projections and recesses in the area surrounding the housing surrounding bezel improve the possibility of contact between the insert and the housing.

This contact can be effectively increased by the fact that a multi-level intimate toothing between the housing wall surrounding the opening and the relevant insert is formed. The contact area in the region of the toothing between the insert and the housing wall is then desirably large. This reduces the electrical resistance in the region of the toothing, which results in an improved HF transition between the insert piece and the housing wall. The according to a development of the invention at least twice existing meander-shaped contact surface in the region of the toothing also represents an improved splash water protection in the region between the insert and the housing wall.

In order to reduce the risk of air gaps between the insert and the housing wall still, can be provided on the side surfaces of the projection from the insert longitudinal ribs or even more selective bulges. The longitudinal ribs or bulges can invest in inserting the insert into the housing pressingly on the housing and at least partially into the housing dig. The emergence of disturbing air gaps between the housing and insert is practically impossible.

On the bottom and the lid part facing the outer surface of the insert, a pin-like or rib-like protrusion may be present projecting. This ensures in a simple manner a particularly dense or pressing installation of the insert also on the bottom and on the cover part of the housing.

Designs for different gears are the subject of further claims and are also shown in the drawing.

Further embodiments and advantages of the invention can be found in the claims further listed in the claims and the following embodiments.

WAYS FOR CARRYING OUT THE INVENTION

For the construction of electronic components, the so-called 19 inch system has become established worldwide. In some countries, this 19-inch system is the basis of corresponding standards. So applies to the in Fig. 1 illustrated rack 10 in Germany, the DIN 41 494. The rack 10 can be installed in cabinets or other switchgear that are standardized by the DIN 41 488.

On the front side 10 differently sized inserts 12 are used in the rack. Not from insertions 12 occupied shelves in the rack 10 are covered by front panels 14. The inserts 12 are also detected by DIN 41 494.

The rack 10 has a height H2, which corresponds to the standardized grid size 3HE in the present example. The front side 16 attached to the insert 12 front plate 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 normalized screen width B1, which is 4TE in the present case.

Within the drawer 12 are one or more printed circuit boards 154 (FIG. Fig. 3 ) inserted inserted. On the front side of such a circuit board 154, a connector 18 is fixed, which is standardized by DIN 41 612. The connector 18 is smaller in its clearance space than the base of the front panel 16. Therefore, the front panel 16 framed the same within the pitch H1 x B1. In the absence of the front panel 16 air spaces around the connector 18 are present around.

On the connector 18, a connector 20 can be plugged, which is present in a housing 22 ( Fig.1,2 ). The plug connector 20 can be connected via a cable 24 leading out of the housing 22 (FIG. Fig. 1 ) be electrically connected to other electrical loads.

Typically, a connector 18 is placed in its formation as a so-called male connector in the slot 12, while in the housing 22, the "female" counterpart, a connector 20 is placed as a so-called female connector.

In the housing 22 a plurality of openings 28 are present, as will be described in more detail below. In one of the openings 28, the cable 24 is held by an insert formed as a crimp flange on the housing 22, as will be described in more detail below. Other housing openings, which at the in Fig. 1 configuration shown are not required, are closed by inserts designed as blind plugs. The formation of the housing openings 28 with the different inserts will be described in more detail below.

The housing 22 is formed immunity to radiation. It is made of metallic material. From this housing 22 is in Fig. 2 his trough-like bottom part 25 is shown, which is closed by an outline of the bottom 29 of the bottom part 25 corresponding, not shown in the drawing, cover part. In the cavity located between the bottom part 25 and cover part, the interior space 26, there is room for the connector 20 and its line connection technology to the lead out of the housing 22 cable 24th

In the housing 22 24 different openings 28 are in the bottom part 25 framing side wall 30 for taking out one or more cables.

The housing 22 can be screwed to the slot 12. As a result, a permanent contact between the connector 20 and the mating connector 18 can be ensured. The respective screw connections are in - in Fig. 2 Upper and lower - end-side end portion 32, 34 of the connector housing 20 surrounding housing opening 36. In the two end portions 32, 34 sits a screw 38, which can be screwed into a nut piece 40 respectively. These two nut pieces 40 sit in an upper and lower rail support 42, 44, which on the rack 10 are attached. The housing 22 can thereby be screwed with a press fit to the rack 10.

The housing 22 sits with his in Fig. 2 upper end portion 32 directly on the upper rail support 42. There is direct physical contact between the housing 22 and the rail support 42. The other end portion 34 of the housing 22 is illustrated directly adjacent to a front panel 16 drawing. The front plate 16 in turn has direct contact with the contact present behind it rail support 44 (FIG. Fig. 2 ). In Fig. 2 Therefore, both the state is shown that the housing 22 is screwed directly to the rack 10, in the absence of front panel, as well as the state that the housing 22 is bolted to an existing front panel 16 seated on the rack 10.

Regardless of whether a front panel 16 is present on the drawer 12 or not, the connector 20 must always have the same orientation and distance to the slot 12 in its assembled with the mating connector 18 state. That is, when a front panel 16 is present, the connector 20 protrudes further out of the opening 36 than is the case with the front panel 16 absent. If there is no front panel 16, the connector 20 is recessed lower in the housing 22 than is the case in the presence of a front panel 16. The two states are in Fig. 2 , as already stated, shown schematically. If the front panel 16 is missing, the connector 20 projects out of the housing 22 by the dimension 46. When the front panel 16 is present, the same connector 20 projects out of the housing 22 by the amount 48. The measure 48 is greater than the dimension 46 by the thickness 50 of the front plate 16.

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

In a first type of connector 20, the in Fig. 2 and in the Figures 4.2, 4.3 Schematically represented and corresponds to the design E according to DIN 41 612 come in the two end portions 32, 34 of the housing 22 spacers 52 and 52.2 are used, which are the same as the mirror image, like the Fig. 4.2, 4.3 clarify. The spacers 52 and 52.2 can be used in each end region 32, 34, respectively. Their different installation depends on whether a front panel 16 is present in the region of the mating connector 18 on the insert 12 or not.

In the upper half of the case Fig. 2 the connector 20 is installed extremely far into the housing 22 sunk. The spacer 52 is therefore present in the end region 32 such that its longer angled wall 58 faces the opening 36 and bears against the projecting shoulder 62 of the connector 20 from the direction of the opening 36 (FIG. Fig. 2 . 4.2 ). In the other, not graphically represented corner region 34 would be in this arrangement of the connector 20, the mirror-like spacer 52.2 installed installed, the longer angle wall 58 also from the direction of the opening 36 - and thus in Fig. 2 from the left - rests on the connector 20.

When the front panel 16 is present, the connector 20 protrudes extremely little into the housing 22. In the lower end portion 34, then the spacer 52 is positioned there, as in the lower half of drawing of Fig. 2 becomes apparent. In the other, in Fig. 2 upper end portion 32 would be in this arrangement of the connector 20, the mirror-like spacer 52.2 installed installed. The longer angle wall 58 of both spacers 52, 52.2 lies on each the right side 60 of the shoulder 62 of the connector 20 at. The thickness 64 of the longer angle wall 58 represents the extent to which the connector 20 can be positioned differently far in the housing 22 and corresponds to the thickness 50 of the front panel 16th

In the present example case, a shorter angle wall 59 of the spacer 52, which is aligned at right angles to the longer angle wall 58, flat on the bottom 29 of the bottom part 25. By the arrangement of the shorter angle wall 59 between the shoulder 62 of the connector 20 and the bottom 29 of the bottom part 25, the connector 20 is held in the prescribed orientation within the housing 22, in terms of the distance perpendicular to the bottom 29 of the bottom part 25.

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

Another type of connector 20 is in Fig. 4.4 and 4.5 indicated by the reference numeral 20.2. This connector corresponds to the design F according to DIN 41 612. So that this connector in the (same) housing 22 can be used, and also in two different positions, depending on whether a front panel is present or not, are two different spacers 54th , 56 required. These two spacers 54, 56 are not the same and not the same mirror. If there is no front panel ( Fig. 4.4 ) comes the spacer 54 and in the other case, with existing front panel 16, the spacer 56 ( Fig. 4.5 ) for use. Both spacers 54, 56 are each U-shaped and extend from one end portion 32 to the other end portion 34. In the area between The two end portions 32, 34, both spacers 54, 56 have the same rectangular cross section 66. With the range of this rectangular cross section 66 is the relevant spacer 54, 56 on the cover part of the housing 22 at.

The at the two ends of the rectangular cross-sectional area 66 perpendicularly adjoining body part 68 and 72, which is provided with inserted spacer 54 and 56 respectively in both end regions 32, 34, has the spacer 54 a Konsolartigen projection 70 which on the shoulder 62.2 of the connector 20.2 from the direction of the opening 36 ( Fig. 4.5 ). In the presence of a front plate 16, the spacer member 56 is required, which at the end of the rectangular cross-section 66 each subsequent body part 72 two Konsolartige projections 74, 76 has. The distance 78 between the two projections 74, 76 corresponds to the height of the shoulder 62.2 from the connector 20.2.

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

On the outside, in addition to the spacers 52 or 54 or 56 respectively present in the housing, there is in each case a trench-like recess in the end regions 32, 34 of the bottom part 25. In these trench-like depressions can optionally be an encoder 84 or 86 are installed.

The coding device 84 corresponds structurally 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 to be fastened in the insertion 12.

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

The coding part 90 has a region 102, which has been formed by cutting through a cylinder with a hexagonal base in the center. The region 102 therefore has a jacket of a longitudinally half-cut cylinder of hexagonal cross-section. The inner diameter 104 of the region 102 corresponds to the outer diameter 105 of the Kodierbuchse 88th

At the top, the region 102 is delimited by two hexagonal bodies 106, 108 corresponding in cross section to the plan of the plate 96 of the coding sleeve 88 and the outer contour of the region 102. These spaced-apart bodies 106, 108 have an intermediate cross-section 110 with an outer diameter 112. A longitudinal bore 114 passes through the two bodies 106, 108 and through the region 110. The inner diameter 116 of this longitudinal bore 114 corresponds to the outer diameter 105 of This allows the Kodierbuchse 88 from the direction of the body 106 - in the drawing from above - in the longitudinal direction (longitudinal axis 118) are inserted into the Kodierteil 90 until it rests with its plate 96 from above on the body 106. In the state inserted into the end regions 32 and 34, projections 119 (see FIG. Fig. 2 ) of the bottom part 25 between the bodies 106, 108 and conform to the intermediate portion 110 from the outside. As a result, the coding part 90 is held displaceably in the bottom part 25 in the direction of its longitudinal axis 118. After screwing the cover part on the bottom part 25, the coding part 90 can not fall out of the bottom part 25 also.

In the bottom part 25, the coding part 90 can be used in different rotational orientations. In the present case, six different orientations are possible according to the hexagonal base of the bodies 102, 106, 108 and the plate 96. In addition, the encoder sleeve 88 may be seated in the encoder member 90 in six different rotational orientations. The slot 94 of the encoder sleeve 88 may therefore have six different rotational orientations relative to the encoder member 90.

In the slot 12 are an in Fig. 7 illustrated coding pin 120 and a in Fig. 9 shown, further coding part 122 attached. The coding pin 120 has a circular cross-section rod portion 124 whose outer diameter 126 corresponds to the inner diameter 100 of the Kodierbuchse 88. On the rod portion 124, a longitudinal rib 128 is formed, the cross-sectionally the slot 94 of the Kodierbuchse 88 adapted so that the rod member 124 can be inserted with its longitudinal rib 128 in the region 92 of the Kodierbuchse 88 and then with its longitudinal rib 128 in the slot 94th seated. The Drehausrichtung of the rod portion 124 thus depends on the Drehausrichtung the Kodierbuchse 88, since only then the coding pin 120 can be inserted into the coding bushing 88 when the longitudinal rib can dip into the slot 94.

In the lower region of the rod part 124, a thickened circular-cylindrical region 130 is present. Its outer diameter 131 corresponds to the inner diameter 104 of the coding part 122. The coding part 122 corresponds to the coding part 90; is formed only folding symmetrical to the coding part 90. When juxtaposing the two coding parts 122, 90, their two regions 102 lie against each other.

The coding pin 120 is inserted with its rod part 124 in the coding part 122 of - in the drawing - below. The rod portion 124 of the coding pin 120 may then dip into the coding socket 88, which in turn is seated in the coding portion 90. This joining of the four parts is only possible if the in Fig. 9 Coding part 122 shown "matching" to the in Fig. 8 shown encoding part 90 is positioned. The two areas 102 of the two coding parts 90, 122 must - as shown in the drawing - be aligned parallel to each other. In addition, the encoder pin 120, which may be seated in various rotational orientations in the encoder portion 122, must be aligned so that its longitudinal rib 128 is aligned with the slot 94 of the encoder sleeve 88, as previously discussed.

The coding pin 120 and the coding part 122 sit in a holder, of which half the holding jaw 140 in Fig. 10 is shown. In this holding jaw 140 are formations 142, which correspond to the cross-sectional shape of the body 106, 108 and the intermediate portion 110 of the Kodeilils 122 and the base plate 148, which closes the circular cylindrical portion 130 of the Kodierstiftes 120 below. The base plate 148 of the Kodierstiftes 120 corresponds grundrißmäßig the plate 96 of the Kodierbuchse 88 and corresponds to the base of the body 106 of the Kodeilil 122 or 90. The lowest configuration 142.1 of the holding jaw 140 and 140.2 ( Fig. 3 ) therefore has a height 150, which is composed of 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. The overhang 142.1 present on the shaping 142.1 is adapted to the circular contour of the intermediate region 110 of the coding part 122.

Between two holding jaws 140, 140.2 ( Fig. 3 ), which, as far as the formation 142 is concerned, are identically formed, a coding part 122 with a coding pin 120 located in it can be fixed in position. The two holding jaws 140, 140.2 are screwed by means of a screw 151 (screw axis 152) through a hole 153 in the two holding jaws 140, 140.2 through to a printed circuit board 154 which is in the slot 12.

The coding parts consisting of the coding pin 120 and the coding part 122 are fastened to the printed circuit board 154 in such a way that they are aligned in the direction of the coding parts located in the housing 22. When attaching the connector 20 located in the housing 22 to the attached to the circuit board 154 mating connector 18 emerging from the slot 12 coding parts (coding pin 120, coding 122) immersed in the housing 22 in the coding (coding socket 88, coding 90) , This condition is in Fig. 2 shown.

In the two end regions 32, 34, the encoders 84, 86 located there can be "set" differently. This results in consideration of the hexagonal planform of the different coding parts 1296 (= 6 ⁴ ) different coding positions.

Unless encoding of the housing 22 is desired, the encoders 84, 86 may also be omitted. This has no qualitative disadvantages for the RF-tightness of the housing 22, since the coding means are provided within the thickened end portions 32, 34 of the bottom portion 25 and the corresponding thickened portions of the lid of the lid portion, not shown in the drawing. The encoders are thus within the space occupied by the housing 22 gauge. To the outside, no louvers projecting into the interior of the housing 22 are present if coding devices are present or absent.

The provided in the housing 22 - eight in the present case - openings 28 ( Fig. 2 ) for inserting one or more cables 24 are all the same in the present example case. In each of these openings 28 can be used as dummy plug or Crimpflansch formed inserts. In the following, various such inserts are shown in more detail.

In the housing 22, each of the inserted inserts 220, 226 (FIG. Fig. 12, 11 ) with the respective laterally adjacent side wall 30 of the bottom part 25 a multi-stage toothing 236 (FIG. Fig. 11, 12th et seq.). The multi-stage toothing 236, which is described in more detail below and shown in different variations, represents a comparison with the prior art longer and thus larger area and a more kinking having contact surface between insert and side wall. The electrical resistance between the insert and the side wall is therefore correspondingly small. In addition, the meandering, multi-level toothing provides improved protection against penetrating splash water.

In Fig. 11 is designed as a crimp flange insert 226 shown. It has a through opening 250 with a longitudinal axis 252. This longitudinal axis 252 coincides with the longitudinal axis of a cable 24 inserted into the housing 22. In the insert piece 226, a sleeve 254 is inserted, which by means of two spaced-apart circumferential collar 256, 258 in the longitudinal direction of the longitudinal axis 252 zugs-, pressure-resistant and thus secure against displacement and also still safe against rotation in the insert piece 226. The sleeve 254 is designed to fit the cable 24 in cross section. The cable sheath and optionally a braided shield are in the assembled state on the sleeve 254 close to, while the wires of the cable are performed by the sleeve 254. On the cable sheath another sleeve, not shown, is pushed and squeezed against the jacket. As a result, the sheath can be fixedly mounted on the sleeve 254. This attachment of a cable to the sleeve 254 is known.

The insert 226 ( Figure 11 ) has in the present case a parallelepiped body 260 with a continuous opening 250. From this body 260 collar on its two opposite side walls 262, 264 each have two projections 266, 268 from. The two side walls 262, 264 abut when installed on the side wall 30 of the housing 22.

In the direction perpendicular to the longitudinal axis 252, the two projections 266, 268 project by the length L from the side wall 262 and 264, respectively.

Each projection 266, 268 has side surfaces 270, 272 projecting from side wall 262, 264 and abutting the body and side walls 262, 264, respectively. One side surface 270 is aligned at a non-90 degree angle 274 to side wall 262, 264. Your Lateral length LS projecting from the side wall 262, 264 is thus longer than the corresponding projecting length L of the other side surface 272, which protrudes from the side wall 262 or 264 at a right angle 276. The cantilevered summed length of both side surfaces 270, 272 of both projections 266 (or 268) is 2 LS + 2 L, which is greater than 2 L.

On each side surface 270, a longitudinal rib 280 is formed. Upon insertion of the insert 226 into an opening 28, the longitudinal rib 280 rubs against the abutting surface or contact surface of the side wall. As a result, a dense system or a continuous contact contact between the insert and the side wall is given. The projections 266, 268 with the longitudinal ribs 280 are formed so that the insert 226 can be used with a press fit of "top" on the freed from the cover part bottom part 25. In the side wall 30 are corresponding indentations and projections which are adapted to the projections 266, 268 and their mutual arrangement accordingly. The insert 226 then sits with a press fit in the side wall 30th

In addition to the insert 226, which is provided in the region of an electrical cable 24 to be inserted into the housing 22, the housing openings adjacent thereto in the present example are closed by the insert 220 (FIG. Fig. 12 ). This insert 220 represents a blind plug, as already stated. The insert 220 has the same projections 266, 268 and longitudinal ribs 280 as the insert 226 and is seated with a corresponding interference fit in the side wall 30. Its opening 282 is closed at one end by a wall 284 on one side. As a result, the insert 220 forms a closure for the relevant opening in the side wall 30. The insert pieces 220, 226 can optionally be inserted into the openings 28 of the housing 22.

This in Fig. 13 22.2 partially illustrated housing 22 differs from the housing 22 by a slightly different teeth 236.2 of the inset in the housing 22.2 inserts 220.2 and 22.2 insertable into the housing insert 226.2 ( Fig. 14 ). Also, the teeth 236.2 and thus also the insert 226.2 each has two laterally projecting projections 266.2 and 268.2. In contrast to the insert 226 is the insert 226.2 and thus in the teeth 236.2, the side surface 270.2 in the same manner as the respective opposite side surface 272 aligned at right angles to the side wall 262 and 264 of the parallelepiped body 260. The cantilevered length L of the two projections 266.2 and 268.2 thus corresponds to the canting length LS of each side face 270.2 and 272, respectively. For the insert piece 226.2 and its projections 266.2 and 268.2 respectively, the added cantilevered length of the respective two projections 266.2 and 268.2 is 4 LS. This value corresponds to the value 4 L.

This in Fig. 15 shown housing 22.3 corresponds to the above-described housings with the difference of a different teeth 236.3 between the respective insert 220.3, 226.3 and the respective side wall 30. From the cuboid body 260 of the insert 226.3 ( Fig. 16 ) projects laterally in each case a single dovetail-shaped in cross-section projection 266.3, 268.3. Its opposing side surfaces 270.3, 272.3 are obliquely to the longitudinal axis 252 available. Its length LS is thus greater than the projecting length L of the respective projection 266.3 or 268.3. It applies to each projection that the two lengths LS are greater than both lengths L.

In the case 22.4 ( Fig. 17 ) there is a toothing 236.4, which is composed of a rectangular in plan projection 266.2 (268.2) and a triangular projection 266.4 (268.4). The laterally opposing side surfaces 270.2 and 272 in the projection 266.2 and 270.2 and 270.4 in the projection 266.4 are partially rectangular (side surface 270.2, 272) or obliquely (side surface 270.4) formed on the insert 226.4 or as a blind plug 220.4 formed insert. The summed length of all protruding side surfaces of the projections on one side of the parallelepiped body is 3 L + LS and is thus greater than 2 L.

Also with the gearing 236.5 ( Fig. 19 ) of the housing 22.5 is between the insert 220.5 or 226.5 and the respective side wall 30 of this housing, the summed Kraglänge as large as in the teeth 236.4 according to FIGS. 17 and 18 , The only difference is that there is a longitudinal side surface 273 between the oblique side surface 270.4 of the projection 266.4 and the adjacent side surface 272 of the adjacent projection 266.2 oriented at 90 degrees to the longitudinal axis 252.

Also in Fig. 21, 22nd shown toothing 236.6 between an insert 220.6 and 226.6 and the relevant side wall 30 of a housing 22.6 has these above accumulated Kraglängen or side wall lengths of 3 L + LS. In contrast to toothing 236.4 ( Fig. 17, 18 ) lies in the cross-sectionally triangular projection 266.4 with its upper side surface 270.2 in the drawing flush with the outer surface of the cuboid body 260, while this in the toothing 236.4 ( Fig. 17,18 ) is not the case. The local projection has 266.4 a recess 290 to the corresponding outer wall of the cuboid body 260th

The teeth 236.7 in the case 22.7 or insertable into these cases inserts 220.7 and 226.7 ( Fig. 23, 24 ) has two projections 266.2, 268.2, as well as in the teeth 236.2 ( Fig. 13, 14th ) available. The upper projection 266.2 or 268.2 of the toothing 236.7 in the drawing is flush with the outer wall of the parallelepiped-shaped body 260, as is similar to the toothing 236.6 (FIG. Fig. 21, 22nd ) the case is. In contrast, in the toothing 236.2 according to Fig. 13, 14th a recess formed by a side wall 262 between the projection 266.2 and the outer wall of the parallelepiped body 260 is provided. In the toothing 236.7 a rebuilt length of the projections as in the teeth 236.2 in the following manner: 4 L = 4 LS.

In the FIGS. 25 and 26 shown toothing 236.8 of the housing 22.8 has a hammerhead training on the relevant insert 220.8 or 226.8. The projection 266.8, 268.8 on each of the opposite sides of the parallelepiped body 260 has a top and bottom in the drawing each single-stage Seitenflächenausbildung, so that each projection 266.8, 268.8 has a two-stage toothing. Each toothing is formed from a step-shaped side surface 273 whose length projecting through the angling is composed of L / 2 + T + L / 2. Both step-shaped side walls 273 thus have summed up a total length of 2 L + 2 T. This measure is greater than 2L.

In the Fig. 27, 28 shown toothing 236.9 of the housing 22.9 is formed like a truncated pyramid. The single projection 266.9, 268.9 of the insert 226.9 has opposite, aligned obliquely to the longitudinal axis 252 side surfaces 270.9 with a respective length LS. The summed lengths of the protruding side surfaces of a projection thus have the length dimension 2 LS. This dimension is greater than the value 2 L. For the inserts 220.9, which are in the side walls 30 as dummy plugs, the corresponding applies. Incidentally, this applies comparatively to all protruding insert pieces 220. The illustrated teeth thus also apply in the same way to corresponding blind plugs.

In a housing various inserts can be present. This concerns once the type of insert. Thus, the insert as a blind plug or as Crimpflansch in the housing and thus be used either for closing an opening 28 or for passing a cable through an opening 28. In a housing inserts with different gears can be used. However, this then requires correspondingly different toothings in the housing wall 30.

On the right angles to the toothed walls of the cuboid body 260 existing two other outer sides of the inserts 226, 220 each have a cantilevered transverse rib 298 is present. The transverse rib 298 is present 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. These transverse ribs abut on the one hand on the bottom 29 of the bottom part 25 and on the other hand from the inside to the cover part, not shown in the drawing, which rests tightly from above on the bottom part 25 and thus also on the inserts 220 and 226. The inserts 220, 226 and The inserts shown above, differing by the respective teeth thus not only have an intimate touch contact caused by their respective teeth and the longitudinal ribs 280 press fit with the walls 30, but also a splash-proof system on the other walls adjacent the inserts, namely the Bottom 29 and the lid part. The housing 22 thus lies circumferentially close to the outer surfaces of the insert piece 220 or 226.

To identify the respectively existing housing 22, a logo 160 and a type designation 162 are plastically made visible on the bottom 29 of the bottom part 25 by corresponding positive or negative shaping of the bottom. Comparable markings can also be provided on the cover part.

This in Fig. 29 Thus, the cross section of the housing 22.2 is the same size as the cross section of the housing 22, so that the housing dimensions of a 3U x 4TE front panel of the initially mentioned 19 inch system correspond.

Compared with the housing 22, larger openings 28.2 are provided in the housing 22.2, so that correspondingly large and / or several cables can be led in or out simultaneously through a corresponding opening 28.2 in the housing 22.2. Thus, even a plurality of cables can be brought into or out of the housing 22.2 in close proximity to one another with the same cable clamp.

According to Fig. 29 is in the housing 22.2, as well as the housing 22, the above-mentioned connector 20 placed. Its counterpart, the connector 18, is as already stated above, arranged in the slot 12 ( Fig. 1 ). Moreover, with respect to the formation of the housing openings 28.2 the above to the openings 28 already executed.

The housing 22.2 is designed to be resistant to interference radiation and made of metallic material. By means of two screws 38 in the present case, the housing 22.2 can be screwed to the insert 12, as already described above for the housing 22. Depending on whether there is a front plate 16 on the insert 12 or not, the housing 22.2 sits differently close to the insert 12. Nevertheless, the same applies to the housing 22.2, as well as the housing 22, that the present in the housing 22.2 connector 20, regardless of whether the plug-in 12 a front panel is present or not, with its mating connector 18 in the assembled state always the same orientation and distance to the slot 12 has. This different positioning is, as already mentioned in connection with the housing 22, made possible by different spacers 52.4, 52.6, 54.2 and 56.2.

In a first type of connector 20, the in Fig. 29 is shown schematically and corresponds to the design E according to DIN 41 612, come in the two end portions 32.2, 34.2 of the housing 22.2 spacers 52.4 and 52.6 are used. In the absence of a front panel, in the housing 22.2 in the left and in the right-hand end area 32.2, 34.2 there is a respective spacer 52.4 (FIG. Fig. 30, 32nd ). With existing front panel, which state in the right half of the Fig. 29 is shown sitting in the left and in the right end portion 32.2, 34.2 respectively 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 in Fig. 32 lower side is a narrower, in cross-section approximately rectangular bar 312 available. The shorter leg 314 is rectangular in cross-section and ends in a central square piece 316. The spacer 52.6 consists of the body of the spacer 52.4, wherein in addition to the square piece 316 a parallel to the longer leg 310 extending, in cross-section contrast smaller square bar 318 integrally formed is.

In the context of the Figures 4.4 and 4.5 mentioned other type 20.2 of connectors 20 are in the FIGS. 34 and 35 shown spacers 54.2 and 56.2 are used to position the connector 20.2 in the same way to the mating connector 18, regardless of whether a front panel 16 is present on the housing 22.2 or not. The two spacers 54.2 and 56.2 differ from the above-mentioned spacers 52.4 and 52.6, first of all in that, as is the case with the spacers 54 and 56, they are U-shaped. The existing in the left and right end portion 32.2, 34.2 spacer sections are connected to each other in this other type of connector 20.2 by a connecting member 320 having a rectangular cross-section 66. In the spacer 54.2 whose two ends at the end of the connecting part 320 two body parts 322, 322.2 are mirror images of each other, otherwise the same in cross section. The two body parts 322, 322.2 have an approximately chair-like shape. In the spacer 56.2 whose two end body parts 324, 324.2 are also the same shape in cross section and aligned in mirror image to each other. The "seat" 326 in the body 322 or 322.2 and the U-shaped indentation 328 in the body part 324 or 324.2 allow a corresponding connector 20.2 of different height relative to the connecting part 320 of the respective spacer in the Housing 22.2 can be placed. The different height orientation of the connector 20.2 takes into account the presence or absence of a front panel 16.

Outwardly, as well as the housing 22, also in the housing 22.2 in addition to each in his existing spacer parts 52.4, 52.6 or 54.2 or 56.2 each have a trench-like recess 330, 332 available. These recesses 330, 332 are larger in cross-section than the corresponding recesses in the housing 22. In the recesses 330, 332 can be in the present example, not only a coding 90.2 ( Fig. 37 ) but also on the circuit board 154 ( Fig. 31 ) attached handle 340 and 342, respectively. The recesses 330, 332 are therefore larger in cross-section than the corresponding recesses in the housing 22.

At the in Fig. 29 upper end of the recess 330 and 332 sits a coding part 90.2. This coding part 90.2 corresponds to that in Fig. 8 shown coding part 90, which relates to its external dimensions. The coding part 90.2 lacks the longitudinal bore 114 present in the coding part 90. As a result, the region 102.2 of the coding part 90.2 (FIG. Fig. 37 ) formed at Kodierteil 90 due to the longitudinal bore 114 trough-shaped concavity. Due to the hexagonal cross-sectional shape of the end-side body 106 from the coding part 90.2, the coding part 90.2 can be placed in six different positions in the recess 330 or 332. The coding part 90.2 does not touch the wall regions adjacent to it in the respective end region 32.2 or 34.2. Namely between the coding part 90.2 and the wall portions of the housing 22.2 is still room for the wall 336 of the handle 340 and 342. Each handle 340, 342 has a blind hole opening, the cross-sectional shape of the body 106 of the coding 90.2 corresponds. Also on the handle 340, 342, a coding 90.2 can be used in six different layers. The handle 340, 342 is formed in two parts to allow a firm hold of the coding used in it 90.2.

As the FIGS. 29, 30 make clear, the handle 340, 342 can be inserted from below into the respective recess 330, 332. The in the recess 330, 332 each einitzend Kodierteil 90.2 slides partially on the located in the handle 340, 342 counter-coding 90.2. With mutual "same" orientation 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 or 342 ensures that only the correct housing 22.2 can be attached to the relevant circuit board 154.

The handle 340 and also the handle 342 have an outwardly molded shoulder 344, 346. In the assembled state of the two connectors 20 and 20.2 of the housing 22.2 and the mating connector 18 of the circuit board 154 also disappears the shoulder 344 and 346 in the recess 330 and 332. After loosening the screws 38 and then removing the housing 22.2 of the circuit board 154, the two handles 340, 342 are exposed. The two handles 340, 342 can then be pivoted outward, resulting in Fig. 36 is indicated. The shoulders 344, 346 press from the outside or on top of the circuit board 154 surrounding firmly connected to the slot 12 areas, such as on a front panel 16th

In Fig. 36 is a front plate 16 indicated by dash-dotted lines on which from above the respective shoulder 344 and 346 of the left and right handle 340, 342 is present. The two handles 340, 342 are drawn through. By pivoting the two handles 340, 342 outward, the holders 350, 352 of the printed circuit board 154, which are fastened to the handles via the axes of rotation 338, are moved upward. By outwardly pivoting the two handles so the circuit board 154 from the slot 12 something - in the present case by about 3 mm (millimeters) - are pulled out. As a result, the existing on the back of the insert 12 contacting can be solved. By pivoting outward of the two handles 340, 342 so the fixed contact of the circuit board 154 in the slot 12 and thereby solved the circuit board 154 - based on the Fig. 1 - Be pulled out the front of the slot 12. The holders 350, 352 are each formed in two parts and screwed by means of a screw 151 (screw axis 152) to the inset in the slot 12 einitzenden circuit board 154.
