Description

TECHNICAL FIELD

The invention relates to a bus housing and in particular to an interference-proof bus housing electromagnetic, which is designed for the connection of a D-Sub plug connector (D Subminiature ["D-Subminiature"]) and at least two electric wires. The invention relates also to inserts that are inserted in the openings to bus housing cables in order to close the housing or OK to fix a cable to it.

The D-Sub plug connectors are standardized, as for example by the German standard DIN 41652. In the inside a bus housing provided with one of these D-Sub plug connectors terminate the souls of some wires electrical Souls can connect with conductivity Electrical to the plug connector contacts

directly

or indirectly to through from a license plate from

circuits

printed. Is frequent place several from such

Bus enclosures very close.

CURRENT STATE OF THE TECHNIQUE

From DE 29719841 U1 a housing is known of electromagnetic interference-proof bus, in one from whose sides a D-Sub plug connector can be connected and on whose opposite side two wires can be connected electrical The two cable entry openings are arranged in the form of a ladder, the axes being lengths of the cables to be connected arranged in parallel with each other. Inside the housing you can

a printed circuit board as an element of electrical connection between the plug connector and the souls of the two wires. These types of housings can be placed very next without prejudice to the two cables that come out of each housing. The cables are held in the openings of the respective housing in a tensile-resistant manner by inserts that have a queue-like configuration of dove The dovetail configuration allows both an optimal tensile discharge for the cable to connect as an extremely effective electrical connection of the cable shielding. Whenever an exit is not required cable, the corresponding opening of the housing is closed with a plug that also presents said configuration as dovetail.

EXHIBITION OF THE INVENTION

Starting from this state of the art already known, the invention aims to indicate a bus housing of the type mentioned at the beginning that is as small as possible, to which a D-Sub plug connector can be connected and that have two cable entry or exit openings very next.

This invention is given, for susceptible inserts to be inserted in the cable openings of the housing bus, through the features of claim 1 and, for the bus housing designed for such inserts, by the characteristics of claim 14. The object of the other claims that follow these claims they are convenient improvements of the invention.

The inserts according to the invention and a bus housing equipped with such inserts allow to have very close and

parallel to each other, two cables connected to a housing bus of this type. A bus housing provided with such two cable inputs or outputs can be at the same time configured with a size so small that its section transversal practically does not need to be greater than defined and preset by the gauge of a connector 9-pin D-Sub plug. In addition, such housings can be placed next to each other, with the corresponding space saving, and still screwed firmly and in a safe mode using, respectively, two screws a front panels or other subset components.

The insert to be used in such a housing can be a plug that closes the cable opening corresponding or a pressure crimp flange that allows fasten a cable to the bus housing in a resistant manner to the traction and with good electrical connection. The insert is a One-piece component, with a groove surrounding the less in part. This slot corresponds to a nerve, which protrudes into the cable opening of the housing and surrounds it at least in part. The slot of the insert and the nerve of the cable opening are mutually adapted in shape so that the insert can be inserted in the bus housing in a tensile and A good electrical connection. In the opening can be inserted also, instead of the pressure crimp flange, a sealing plug also provided with the groove that runs to the less partly the periphery of the pressure crimp flange, so that in each cable opening of the housing you can optionally insert a plug or a flange Crimp to connect a cable. Through a shutter cap can be tightly closed an opening for cables

it may have a surface area that has no symmetry of rotation, so that it can settle safely against torsion in the cable opening of the housing.

The insert configured as a pressure crimp flange It has an annular area that has two flange collars mutually separated peripherals. Between the two collars of flange is configured the aforementioned slot that runs through the at least partially periphery. At least one of the two flange collars can have at least one area flat flat surface, in order to configure it of Safe way against torsion. The flat surface area flat, which can be present in at least two areas surface flange flanges, opposite each other, reduces the surface of the circular cross section initially existing, so it is possible to configure the insert with a very small width and with it also configure the cable opening of the housing correspondingly narrow. Preferably they can exist also several "flattening" corresponding to the form of square or rectangular contour, as the shapes show by way of example. In this way it is possible have two housing openings extremely close adjacent, which makes possible dimensions of the housing cross section, correspondingly small in the direction through both openings.

The cap portion of the insert following the zone annular is configured as a pressure crimp flange and has preferably at least one surrounding groove, for allow a sturdy sliding seat to the extent of

the possible of a cable cover placed in the part of cap. The free end zone configuration cap with a conical wall narrowing facilitates the placement of a cable cover in the portion of cap

The insert is snapped with its grooves in the nerves of the cable opening. The pressure seat of the insert thus created in a cable opening can be further enhanced by stamping the surface front of one of its flange collars. These prints produce a very small molding of the material in the opposite front surface of the flange collar, with the that the latter rests on the nerve of the opening to cables.

A bus housing designed for such inserts, configured in a particularly strong way electromagnetic interference and provided with two screws fixing can present two cable openings with a axial separation between them from 10 to 13 mm (millimeters), especially 11.5 mm. The minimum possible distance with the pressure crimp flanges existing in the current state of The technique is more than 14 mm.

Two bus housings according to the invention represented in the drawings, which are equipped with cable openings in which are inserted the inserts according to the invention, they have a first housing portion that presents essentially form of parallelepiped and in one of whose ends can connect a plug connector, as in the example present a 9-pin D-Sub plug connector. The cross section of this first housing portion corresponds to the size of the 9 D-Sub plug connector poles At the other end of the first housing portion in

parallelepiped shape is a portion of neck whose cross section is comparatively more little. This neck portion is attached in one piece to the first housing portion. The neck portion follow a head portion whose front part is the two cable openings. The housing consists of a lower portion, which essentially has a bucket shape, and of a cover, essentially in the form of a plate. Serving bottom and cover can be screwed together through the lid In the case at hand, screwing is done with three screws, of which one is in the area of transition between the head portion and the neck portion and is centered in said area between the two openings.

The heads of the two fixing screws by which can be screwed the housing for example to a front panel are located on the outside of the portion of neck. Thus, it is possible to freely access the heads of the screws from the outside with a tool turn.

The head portion may also be oriented of inclined shape with respect to the longitudinal axis of the housing, without thereby impairing the accessibility of the fixing screws.

Two other bus housings of this type according to the invention, represented in the drawings, envelop the plug connector for the most part, bringing its width is larger than the corresponding width of a connector 9-pin D-Sub plug. In addition, in the angular form of the housing, the neck portion is configured so that it narrow only on one side; the narrow longitudinal side opposite the angle extends in a straight line from the area

from the plug connector to the head area of the Case.

Of the characteristics mentioned later in the claims and of the embodiments following other configurations and advantages of the housing according to the invention and the inserts inserted in said housing.

EMBODIMENTS OF THE INVENTION

A bus housing 10 has a lower portion of housing 12 (figure 2) in the form of a bucket, on which it is screwed (figure 1) a housing cover 14, shaped approximately plate, by means of three cover screws 16, 18, 20. The housing 10 has a first portion of housing 22 having approximately square shape. TO this housing portion 22 follows -in figure 1 towards the right - a portion of carcass neck 24. The portion of casing neck 24 ends -in figure 1 towards the right -in a housing head portion 26. While that, in the present example, the width 28 in the area of the first housing portion 22 is 31 mm (millimeters), the neck portion 24 has a width 30 of only 19 mm. The

portion

from head 26 have a width 32 from 22.5 mm The

height 34 of the

Case from bus 10, what pu ede be seen in the

Figure 5, is 14.8 mm steadily.

The width 28 and height 34 of the housing 10 have dimensions adapted to a D-Subminiature plug connector 36, which in the case at hand has 9 poles. In the figure 1, this plug connector 36 is located on the side left of the first housing portion 22.

In the present example, the length 38 of the housing of bus 10 is 48.5 mm, from head portion 26 to before the peripheral flange 39 of the plug connector 36.

Both the lid 14 and the lower portion 12 have a flange 40 extending the housing 10 to the extent of a length 42 of, in the present example, 2.5 mm. This flange 40 laterally borders flange 39 of plug connector 36 from the direction of the lid 14 and the lower portion 12. The plug connector 36 is housed with said flange 39 in about slots 44 that are respectively formed in the flange 40 of lid 14 and flange 40 of the portion bottom 12 (figure 4).

In the case at hand, they are introduced both in the lid 14 as in the lower portion 12 small cavities 45, which have different sizes and approximately rectangle. These cavities 45, which facilitate the grip of the housing 10, may additionally have a nature graph. In addition they can also accommodate, at least in part, labeling labels without increasing the height 34 of the housing 10.

The lower housing portion 12 has a bottom 46 at that join at a right angle and in one piece a wall left side and a right side wall 48, 50. On the plug connector area 36, the two side walls 48, 50 each have a thickening 52 in which respectively it is, at a right angle to the bottom 46, a drill 54 with an internal thread. These two drills 54 allow the lid 14 to be screwed to the portion bottom 12 by means of its two screws 16, 18. For the third cover screw 20 is provided, in the area of transition from neck portion 24 to head portion 26, in the area of the longitudinal axis 56 of the housing, a bushing 59 which is provided with an outgoing internal thread from bottom 46 at right angles.

The two side walls 48, 50 of the lower portion 12 also delimit the neck portion 24 and the portion of head 26. Because the width 30, 32 of these two portions 24, 26 is different from that of the first portion of housing 22, the two side walls 48, 50 draw an arc correspondent. In the transition zone between the first housing portion 22 and neck portion 24 is provided respectively a recess 58, and through these recesses 58 pass the stems 60 of two screws of fixing 62, 64. The respective ends 66 of these two fixing screws 62, 64 protrude from the front side of the two thickening 52 which is oriented towards the plug connector 36. The two shafts 60 of the screws fixing 62, 64 extend below the holes 54, so that the cover screws 16, 18 do not collide with the fixing screws 62, 64.

The respective heads 68 of the two screws of fixing 62, 64 are located on the side, outside the neck portion 24. The head portion 26, which is something wider than neck portion 24, it has only one width such that it is still possible to screw with a tool turn heads 68 and, with them, the screws fixing 62, 64 to a front panel, for example, and with it screw the bus housing 10 to said front panel and unscrew it again.

In the present example there is, inside the lower housing portion 12, a circuit board 70s to which they are connected, in the present 9-pin plug connector 36, the nine pins of corresponding 72 connection. Through a soldered terminal 74, the printed circuit board 70 has a connection to ground by means of a grounding screw 76. The

grounding screw 76 is in the area of the neck portion 24, and within it on the longitudinal axis

56. On the printed circuit board 70 there is a terminal of connection 78 with a maximum of nine, in the case at hand eight, connection possibilities for souls 80 of two cables 82, 84 inserted in the housing 10. The introduction of the cables 82, 84 is made through the front side in figures 1 and 3 - right 86 of the housing 10 by two pressure crimp flanges 88.

The two pressure crimp flanges 88 are set in the same way. A flange to crimp to pressure 88 has an annular zone 90 followed by an area of bushing 92 (figure 7) of smaller cross section. The annular zone 90 and socket area 92, are firmly linked together and, in the case at hand, are jointly represented as a turning element of a single piece

In the annular zone 90, between two flange collars 94, 96, a peripheral slot 98 is configured. With the slot 98, the pressure crimp flange 88 sits on a nerve circular 100, 102 (figures 4, 6), configured both in the lower portion 12 as in the cover 14. Thus, the flange collars 94, 96 are supported closely by both sides in the corresponding nerve 100 or 102.

In the present example, flange collar 96 has a diameter somewhat larger than flange collar 94. In its two diametrically opposite outer sides, the collar of flange 96 has a flat surface 104, 106. These two flat surfaces 104, 106 are produced by a subsequent milling of the body of revolution. With the help of both flat surfaces 104, 106 of flange collar 96, the snap-on flange 88 sits securely

against twisting in the respective opening 110, 112 on the side front 86 of the housing 10 or 10.3. Outer surface axial flange collar 96 is flush with the side front 86 of the housing 10, 10.3. With its cap area 92, the pressure crimp flanges 88 protrude from the housing 10 outwards. In the case at hand in this socket area 92, two grooves are formed peripherals 114, 116, whose purpose is to optimize the firm seat of a cable cover 120 in the pressure crimp flange

88. To slide the cable cover 120 over the area of cap 92 is as easy as possible, the latter It has a cone-shaped wall narrowing 122.

Provided that no cables have to be inserted 82, 84 in the housing 10, the corresponding opening 110, 112 is It closes with a plug 130 (figures 9, 10). This plug 130 corresponds in its outer contour to the ring area 90 of the pressure crimp flange. Unlike of pressure crimp flange 88, flange collar 96 It is part of a 96.9 plate that closes the front side of the sealing plug 130. Thus, the sealing plug 130 it can be inserted into an opening 110, 112 in the same manner as the pressure crimp flange 88 and is also seated in the housing 10 in a tensile and compression resistant manner in the direction of the longitudinal axis 56 and in addition to torsion resistant.

As a result of the configuration in a piece of inserts configured in the form of a clamp flange to pressure 88 or a plug 130, openings 110, 112 can be arranged in the housing 10 with a gap axial 132 very small. Thanks to the configuration in one piece of inserts on the one hand and to the surfaces flat 104, 106 opposite each other on the other hand, this

separation 132 can be configured very small. So, the two flat surfaces 104, 106 are conveniently provided, and therefore the nerves 100, 102 in the zone of the two openings 110, 112 of the front side 86 conform correspondingly, so that the clamping flanges to pressure 88 - and with it also the sealing plugs 130 can be inserted in the lower portion 12 with their flat surfaces 104, 106 parallel to the side walls 48, 50. Only with this orientation of the inserts 88, 130 is it is possible to screw the cover 14 on the housing portion 12 and support it closely from above on inserts 88,

130.

As is known, each cable 82, 84 is fixed to the flange crimping tool 88 by means of a crimping sleeve 140 slid over its cable cover 120. The sleeve of crimp 140 also surrounds the material lining braided shield 142 which, in the flange area of crimp under pressure 88, is driven on the front side of the cable cover 120 correspondingly separated. How It is already known, the crimp sleeve 140 is mounted then under pressure on the cable cover 120, whereby change its circular cross-sectional shape by one way correspondingly polygonal in its cross section.

The bus housing 10.3 shown in Figure 3 corresponds mostly to bus housing 10. The only difference is that its head portion 26.3 is attached to the neck portion 24.3 obliquely, so that the shaft longitudinal 56.3 of the head portion 26.3 is, in the present example, oriented at an angle 148 of 15 ° (degrees sexagesimal) with respect to longitudinal axis 56. In this embodiment, two cables 84, 82 inserted in the

housing 10.3 also have a mutual separation 132 minimum

As in the case of housing 10, the two cables 82, 84 oriented parallel to each other allow several such housings together, in direct contact with each other in the area of its two side walls narrow 48, 50. Each of these housings 10, 10.3 can bolt for example to the front panel of another housing by means of the two fixing screws 62, 64. This allows

a firm fixation of these housings 10, 10.3.

The

heads 68 respective from the two screws from

fixation

62, 64 They are accessible since he Exterior. He

widening 146 of head portion 26, or 26.3,

in

relationship with neck portion 24, or 24.3, allows arrange the screws in the housing impermissibly. Whenever the two recesses 58 through which the rods 60 of the two fixing screws 62, 64 pass are configured in the form of a groove, the two screws 62, 64 can be inserted or removed in a direction of orientation perpendicular to bottom 46. To close these two recesses slit-shaped and prevent screws 62, 64 from “Move” in the screwed position of the housing 10 -lo corresponding is applicable for the 10.3 housing -can be shaped, for example in the cover 14 of the housing 10, two wall elements -not represented in the drawings -which protrude towards the bottom 46 and which, in the position of the housing 10 in which it is joined by the screws, close the space of the two recesses in a notch occupied by the two screw shafts 60.

The bus housing 10.11 shown in figures 11, 12, 18 in a third embodiment also has a bottom portion of bucket-shaped housing 12.11, on

which is also screwed a housing cover 14.11, in approximately plate shape, by means of three screws of cover 16, 18, 20 (figure 11). The 10.11 housing has a first housing portion 22.11, in the form of approximately parallelepiped, which essentially differs from the first portion 22 of the bus housing 10 in which, except for a projection 39 (figure 11), wraps the housing 37 of the connector of plug 36. This projection 39 is sized accordingly that the housing screwed to, for example, a front panel Using its fixing screws 62.11, 64, it can be supported with its front side 87, left in figure 11 and located on the side of the connector, pressed against said panel front and at the same time the plug connector 36 is completely inserted in a counter-piece of said connector existing in a recess of said front panel.

The lower portion 12.11 frames the connector plug 36 with its two narrow side walls 48.11,

50.11. The peripheral flange 39 of the plug connector 36 is rest on a groove 150 molded into each of these two side walls 48.11, 50.11, these slots corresponding 150 to groove 44 molded in lid 14 and bottom 46 of the housing 10 (figure 4). In the area of the peripheral flange 39, the thickness of the two side walls 48.11, 50.11 is reduce accordingly.

To the first portion 22.11, in the form of approximately parallelepiped, from the 10.11 housing follows, on the side opposite plug connector 36, a neck portion of housing 24.11 which, unlike neck portion 24 of bus housing 10 is only narrower than the portion of 22.11 parallelepiped shaped housing on one side. For the both, on the lower side in figures 11 and 12 adjacent to the 50.11 side wall can be used the same screw 64

than in the bus housing 10. Unlike the bus housing bus 10, the two ends 66, 66.11 of the two screws fixing 64, 62.11 do not protrude from the 10.11 housing, since -as explained above -the lower portion of housing 12.11 almost completely frames housing 37 of the plug connector 36.

In the area of the side wall 48.11, the first parallelepiped shaped shell portion 22.11 se transforms in a straight line in the neck portion 24.11 and, continuing in a straight line, in a head portion 26.11 subsequent. The second fixing screw 62.11, which is is in the area of the side wall 48.11, has therefore longer than fixing screw 64.

The front side 86.11 of the head portion 26.11 is inclined toward the longitudinal axis 56 at an angle

148.11 of, in the case at hand, 30 ° (degrees sexagesimal).

In the lower housing portion 12.11 there is a plate of printed circuits 70.11 to which -in the case that we occupies - four connecting pins 72 are connected. The present example, the printed circuit board 70.11 It has two connection terminals 79, which are configured as, so called, tension spring terminals and in the that can be introduced, and firmly connected in what refers to the contact, the souls (80, see figure 2) of two cables inserted into the housing 10.11.

On the front side 86.11 can be firmly inserted two pressure crimp flanges 88.11. These two flanges of snap crimp 88.11 correspond to its bushing area 92 relative to the crimping flanges 88. Its zone ring 90.11 differs from ring area 90 of flanges of crimping under pressure 88 in which the contour of the two

94.11 and 96.11 flange collar is square shaped

108. The axial surface view of the two flange collars 94.11, 96.11 is identical. Between the two flange collars 94.11, 96.11 there is a slot 98, same as in the case of snap-on flanges 88. Since slot 98 is identical, nerves 100, 102 formed in the portion bottom 12.11 and cover 14.11 have the same shape as the ribs 100, 102 of bus housing 10 (figure 13 or figure 6). Since, like flange collar 96, the 96.11 flange collar extends flush with the side front 86.11, in the case at hand it has been emptied in the lower portion 12.11 and on the cover 14.11 a square area 152, in the assembled position of the two pieces, corresponding to the shape of the flange collar contour

96.11. In this embodiment, the flange collar

94.11 existing on the inner side of the lower portion or of the lid could also have a circular contour, such as the presenting flange collar 94 of the crimping flange to pressure 88. The 96.11 square flange collar creates the desired torsion-proof fastening of the crimping flange to pressure 88.11 in the bus housing 10.11. Unlike the pressure crimp flange 88, pressure crimp flange

88.11 can be inserted into the housing with any of its square faces While in the flange of crimp to pressure 88 there are two insertion positions rotated 180 °, in the 88.11 pressure crimp flange there are four different insertion positions.

The plug plug 130.11 represented in the figures 16 and 17 correspond functionally to the plug 130. It has a longitudinal zone 90.16 corresponding to the zone annular 90.11 of the pressure crimp flange 88.11, but of new its 96.11 outer flange collar is part of a

96.17 plate that closes the front side of the plug

130.11. Thus, the sealing plugs 130, 130.11 do not they have a through hole 126 in the form of circular cylinder, existing in both the clamp flange pressure 88.11 as in the clamp flange under pressure 88. As occurs in the case of the plug 130, the plug

130.11 can be inserted in the 10.11 housing just like the 88.11 snap crimp flange, resistant to traction and compression and also torsion resistant.

The axial separation 132 of the two crimping flanges a pressure 88.11 corresponds to axial separation 132 of equal existing size in bus housing 10 or 10.3.

The lower side of the bus housing 10.11 depicted in figure 18 illustrates that the three screws of cover 16, 18, 20 do not cross the lower portion 12.11. As Figure 12 shows, these screws are screwed in holes 54 that are in thickening 52. These thickening protrude from the bottom of the portion bottom 12.11 towards the inside of the housing. the same design has been used in bus housing 10, as illustrated Figure 2

The bus housing 10.19 represented with its side lower in figure 19 corresponds to its first portion of housing 22.19, approximately in the form of a parallelepiped, to the housing portion 22.11 of the bus housing 10.11. So therefore, in this housing 10.19 the fixing screw 64, shorter in length. The portion of neck 24.19 also corresponds to the neck portion 24.11 of the bus housing 10.11. The head portion 26.19 that follow below differs from the head portion

26.11 in which its front side 86.19 is parallel to its side front 87.19 on the connector side. With that, the orientation

length of the two pressure crimp flanges 88.11 is parallel to the longitudinal axis 56.

The head portion 26.19 has, in the direction of the 50.19 shorter side wall and differently than the neck portion 24.19, a widening 154 like the one it also exists qualitatively in bus housing 10. The longest of the two narrow side walls 48.19 has, in the area of the head portion 26.19, a chamfer 156 slightly inclined towards the inside of the housing. This allows you to turn the longer screw without problems

62.11 if several of these are arranged carcasses very close by its narrow sides. This chamfer 156 is also presented by bus housing 10.11.

The two bus housings 10.11, 10.19 have a width 28.11, 28.19 of approximately 32.5 mm. This width is something greater than the width 28 of approximately 31 mm of the bus housings 10, 10.3. The reason for width 28.11 and

28.19 is that, in the two bus housings 10.11 and 10.19, the

flange 39 of plug connector 36 is framed. The shortest length 38.11 or 38.19 of the 10.11 housing or

10.19 is approximately 41.6 mm. The greatest length 38.12 and 38.20 of the two housings 10.11 and 10.19 is of approximately 59 mm. These measures do not include heads of the fixing screws or the areas of the pressure crimp flanges protruding from the housings. These measures also do not take into account the marginal zone narrow of the respective plug connector (projection 39) that protrudes from the housing. The height 34 of the two housings

10.11 and 10.19 is the same as in the case of cases 10 and 10.3, approximately 14.8 mm.

Housings 10 and 10.3 could also be equipped with “square” pressure crimp flanges 88.11; for it

only corresponding squares would have to be formed on the front surface 86. In the reverse case, the housings

10.11 and 10.19 could also be equipped with the flanges of Crimp 88 if they had "round" configurations.
