Description

The invention relates to a data-technology junction box with a terminal block with terminals for laying cable wires, with at least one socket, with receptacle contacts for contacting data cable connectors and means for electrically connecting the terminals and the receptacle contacts.

The requirements for data technology junction boxes have increased steadily in recent years, as ever larger amounts of data to be transmitted. In order to cope with these increased requirements with the known data technology junction boxes, numerous efforts are required, which aim as far as possible to avoid crosstalk between cable wires and in particular contact pairs. Since, for example, in so-called RJ45 sockets must be placed up to eight cable cores per socket and usually two RJ45 sockets are arranged in a data technology junction box, there is only very little space for the then laying a total of 16 cable wires Available. The laying of the cable cores is therefore tedious and time consuming. Finally, known data technology junction boxes are not very flexible with regard to the orientation of the sockets arranged therein since, for example, it is not readily possible to select the plug-in direction differently in the sockets.

With the invention of a flexible and easy to be connected data technology connection box to be created.

According to the invention for this purpose is a data-technology junction box with a terminal block with terminals for laying cable wires, provided with at least one socket with receptacle contacts for contacting data cable connectors and means for electrically connecting the terminals and the socket contacts, wherein the means for electrically connecting terminals and receptacle contacts have releasable connectors.

In this way, the at least one socket and the terminal block can be separated independently of the laying of the cable wires. This considerably facilitates the installation of the data technology connection box, and in particular the laying of the cable wires is considerably simplified. In addition, a flexible structure is achieved because the sockets can be changed without changing the terminal block. For example, the data technology junction box can be changed by simply replacing the socket to different types of sockets. As terminals advantageously terminals with LSA technology, ie soldering, screw and stripping-free technology used.

In a further development of the invention, the terminals are arranged annularly in the terminal block.

In this way, more space can be made available for each of the terminals, as is the case with a straight line arrangement of the terminals side by side. The annular arrangement of the terminals can also be matched in a particularly favorable manner to the round basic shape of data technology junction boxes, which results from the requirement to be able to install data technology junction boxes in standardized wall boxes. The annular arrangement allows, without exceeding the given installation space, to choose a maximum distance between the terminals for the individual cable cores, so that possible interactions between the cable cores can be largely avoided.

In a further development of the invention, the terminals are arranged in a ring around a passage opening in the terminal block around.

This measure makes it easier to hang up the cable cores considerably. After stripping a data cable, the individual cable cores are manually moved away from each other, resulting in a star-like configuration of the then fanned out cable cores. Between two cable cores a V-like gap is thereby enclosed. Such a fanned data cable can be inserted in a particularly simple manner in annularly arranged around a through-opening terminals, wherein the data cable is inserted through the through hole.

In a further development of the invention, the terminal block is annular, in particular annular, formed.

Such an embodiment of the terminal block on the one hand provides a maximum possible distance between the individual cable cores On the other hand, it is optimally adapted to the round basic shape of data technology junction boxes and ultimately facilitates the laying of the cable cores considerably.

In a further development of the invention, a housing is provided and the annular terminal block can be inserted into a plurality of positions rotated about its central axis into the housing.

The annular terminal block can be used for example in 45 ° increments in the housing. This results in a very flexible design, since the terminal block can be used depending on the desired orientation of the sockets in the housing.

In a further development of the invention, the plug-in connectors for the electrical connection of terminals and socket contacts contact pins and contact sockets, wherein in each case a terminal and a contact socket or a contact pin are integrated into a one-piece contact component.

In this way, a simple structure and by integrating each of a terminal, in particular an LSA terminal, and a female contact or a pin in a one-piece contact component transmission losses due to contact resistances can not arise at this contact component.

In a further development of the invention, the contact component is designed as a plate-like sheet metal part.

In this way, results in a simple and inexpensive construction. The plate-like contact components can be inserted, for example, in the terminal block.

In a further development of the invention, the terminal and the contact socket or the contact pin on the contact member are arranged side by side and arranged accessible from the same side of the terminal block ago.

The laying of the cable cores in the individual terminals and the insertion of the sockets thus takes place from the same side of the terminal block ago, advantageously from above, ie from one of the cable feed opposite side. By these measures is comparatively much space to hang up the cable available and then, if after measuring the socket occupancy error is detected, the sockets can be removed again and any incorrect terminal block assignment can be corrected.

In a further development of the invention, the annular terminal block is provided with receiving slots for insertion of the contact components, wherein the receiving slots intersect in the region of the terminals with Kabeladereinlegeschlitzen.

These measures allow the cable cores to be routed through the insertion slots when inserted into the terminals. The annular terminal block is designed so that the cable cores can be inserted with a standard tool in the terminals.

In a further development of the invention, the particular annular terminal block is provided with receiving slots for insertion of the contact components, wherein the receiving slots intersect in the region of the contact sockets with insertion openings.

In this way, a space-saving and structurally simple structure can be realized.

In a further development of the invention recesses are provided in the annular terminal block, which extend at least in sections between adjacent pairs of contact components, wherein in the monierten state of the terminal block arranged on the housing dome-like projections extend into the recesses.

By means of such dome-like projections, which are part of the existing of electrically conductive material housing, a shielding effect between adjacent contact or cable core pairs can be achieved. This allows interference-free transmission with high transmission frequencies.

In a further development of the invention, the contact components are associated with play or floating in the terminal block.

The contact components are advantageously received floating parallel to the ring plane of the annular terminal block. This makes it possible for the contact components to deflect laterally to a limited extent and thereby compensate for position tolerances of the contact pins or contact sockets which are arranged on the side of the sockets. Since any bearing tolerances of the contacts can be compensated on the side of the sockets, a reliable contact between the contact components on the side of the terminal block and the contacts on the side of the sockets can be ensured. The contact components may, for example, have an extension which extends through an opening in the terminal block and is caulked on the opposite side.

In a further development of the invention, the terminal block is provided with locking elements for latching to a housing.

For example, locking lugs or spring arms are arranged on the outside of the annular terminal block, which latch onto the housing. The terminal block can thereby be reliably held in the housing already during installation of the data technology connection box. Advantageously, the connection terminal block is fastened by simply pressing in the housing beyond the latching point of the latching elements.

In a further development of the invention, the at least one socket is arranged on a printed circuit board, which carries on its side facing away from the socket contact sockets or pins.

Such a printed circuit board can then be plugged with their pins or contact sockets in a particularly simple manner in the terminal block. As a result, a separation of sockets and terminals is possible, which, as already mentioned, on the one hand facilitates the placing of the cable cores and on the other hand allows a very flexible use of the data technology connection box according to the invention.

In a further development of the invention, at least two sockets are provided, wherein in each case a socket is arranged on a separate circuit board.

Such a design further increases the flexibility of the data technology connection box according to the invention. For example, a RJ45 socket can be arranged on a left-hand printed circuit board, whereas a standardized telephone socket is located on the right-hand printed circuit board. Because the sockets and the terminal block from each other can be disconnected, this socket assignment can be changed at any time. This change in the socket occupancy requires no change to the terminal block and specifically the necessarily short cut cable cores need not be re-inserted into a terminal block.

In a further development of the invention, the circuit boards are each formed as circular sections or circular segment-like.

In this way, an optimal space utilization is achieved because the circuit boards are adapted to the round basic shape of the data technology junction box.

In a further development of the invention, the printed circuit boards together assume a shape adapted to the diameter of the annular terminal block. The contact pins or contact sockets can be arranged like an annular ring in the edge region of the printed circuit board or in the form of a circle in the edge region of the printed circuit boards.

The annular arrangement of the contact pins or contact bushes is advantageously carried out with the largest possible diameter to space adjacent pins as far as possible from each other. The annular configuration of the terminal block makes it possible to largely maintain this large distance between the individual pins or contact sockets and only in the field of cable wires itself, the distance of the individual signal paths is then significantly reduced again. Overall, these measures contribute to a very good frequency response of the data technology connection box according to the invention.

In a further development of the invention, the at least one socket, which has the contact pins or contact sockets, on a housing insert fastened, which is formed in a housing and slidably mounted on the terminal block, wherein the housing insert and the terminal block by means of at least one fastening screw are movable toward each other, wherein the fastening screw is parallel to the direction in which the housing insert with the at least one socket and the Contact pins or contact sockets can be pushed onto the terminal block.

Through these measures, the sockets can be mechanically and electrically connected by simply pushing on the terminal block. Pushing is done, for example, manually and the end position is then achieved by tightening the mounting screw. The fastening screw presses with its head advantageously the housing insert in the direction of the terminal block and is seated with its opposite end either in the terminal block or, as is preferred according to the invention, in a thread in the housing.

In a further development of the invention, the housing insert and the at least one socket are connected to one another via latching means.

In this way, the at least one socket, advantageously indirectly via a latching of a printed circuit board on which the socket sits, are connected to the housing insert and housing insert and socket can then be pushed together on the terminal block.

In a further development of the invention, the at least one socket and the contact pins or contact sockets are arranged on a printed circuit board, wherein the circuit board is connectable to the housing insert by means of the locking means.

The circuit board with the at least one socket can thereby be secured to the housing insert against relative movement in Aufschieberichtung on the terminal block and also in the opposite direction of withdrawal. It is thereby possible to postpone the circuit board together with the at least one socket and the housing insert both on the terminal block as well as deduct again from this. In this case, a force causing the pushing on and off can only act on the housing insert.

In a further development of the invention, the housing insert is pot-shaped and surrounds with its peripheral pot wall in the assembled state, the terminal block laterally at least partially.

Since the housing insert at least partially surrounds the terminal block laterally, insulation of the terminal block in the lateral direction against the housing can be achieved. The housing insert is for this purpose made of electrically non-conductive material, the housing is made of electrically conductive material, such as zinc die-cast. The housing insert may laterally insulate the terminal block against the housing at least in those areas where the individual laid-up cable cores are located radially with their uninsulated cable ends in the terminal block. When laying the cable wires on the terminal block, the ends of the cable wires are cut substantially flush with the outer wall of the terminal block. However, it can not be avoided that the open, uninsulated cable ends protrude slightly beyond an outer boundary of the terminal block. At least in these areas, the circumferential pot wall of the housing insert laterally surrounds the terminal block to isolate the open cable wire ends from the electrically conductive housing.

In a further development of the invention, the circuit board is inserted into the pot-like housing insert and secured by means of locking lugs on the inside of the pot wall.

As a result, on the one hand, a secure fixing of the printed circuit board in the housing insert and, on the other hand, an electrical insulation of the printed circuit board can be achieved.

In a development of the invention, the housing insert can be connected to a housing cover and the housing cover can be moved away from the terminal block by means of at least one fastening screw parallel to the sliding direction of the contact pins or contact sockets of the at least one socket.

In this way, the at least one socket can be removed from the terminal block by means of the fastening screw. Advantageously, the fastening screw simultaneously serves to move the at least one female connector together with the housing insert onto the terminal block. Conveniently, two fastening screws are provided, which are arranged for example right and left of the at least one socket. By screwing in the fixing screws, the socket can then be moved towards the terminal block until the fully inserted position has been reached. By unscrewing these two mounting screws, the at least one socket can then be released again from the terminal block. The socket is moved together with the housing insert. When unscrewing the screw head of the fastening screw thereby supported on the underside of the housing cover, whereby the housing cover is moved away from the terminal block and, since this is connected to the housing insert, and the housing insert together with the at least one socket away from the terminal block.

In a further development of the invention, the housing cover is provided with a passage opening which is aligned with the fastening screw and whose diameter is smaller than the diameter of the screw head of the fastening screw.

In this way it is possible to attack with a tool, such as a screwdriver, on the head of the fastening screw and unscrew the fastening screw until its head rests on the edge of the through hole in the housing cover. By further unscrewing the fastening screw of the housing cover is then moved together with the screw head, namely away from the terminal block. The fastening screw is advantageously supported in a thread in the housing. However, since the terminal block is held on the housing by means of locking means, the housing cover can be moved away from the terminal block and thereby take the housing insert and the at least one socket with the contact pins or contact sockets.

In a further development of the invention, the housing insert is connected by means of a printed circuit board to the housing cover and the at least one female connector with the contact pins or contact sockets is connected to the housing insert.

By moving the housing cover away from the terminal block, the housing insert is simultaneously moved along with the sockets and thereby the contact pins are pulled out of the contact sockets on the terminal block. The housing insert is advantageously latched to the housing cover, the at least one socket is mounted on a circuit board, in turn, on the housing insert is locked and the terminal block is also attached via locking means on the housing.

In a further development of the invention, a distance between a contact surface for the head of the fastening screw on the underside of the housing cover and a spaced therefrom in the direction of the housing insert support surface for the head of the fastening screw is shorter than the length of the fastening screw. For example, an open towards the outer periphery of the housing cover slot is provided on the housing cover into which the fastening screw can be inserted. The opposite Berandungsabschnitte at the open end of the slot can be designed so that they can be caulked after insertion of the mounting screw and thereby hold the mounting screw captive, since the still existing after caulking opening slot of the elongated hole is narrower than the outer diameter of the mounting screw. Alternatively, the distance is dimensioned so that the fastening screw can be introduced obliquely between the contact surface on the underside of the housing cover and the bearing surface spaced therefrom. The fastening screw can thereby be introduced obliquely between the housing insert and the housing cover, but the distance between the contact surface and support surface is so small that the fastening screw are used both for the removal and the pressing of the at least one socket from the terminal block or in the direction of the terminal block can.

In a further development of the invention, a laterally open screw channel is arranged below the contact surface on the underside of the housing cover whose inside diameter is greater than the diameter of the screw head of the fastening screw and at its opposite end of the bearing surface, the bearing surface is arranged for the head of the fastening screw.

Conveniently, two such screw channels are arranged on opposite sides of the housing cover. The contact surface surrounds the passage opening in the housing cover and the screwdriver is inserted through the passage opening. A connection between the housing cover and housing insert is effected by a latching connection. However, the fastening screw is guided exclusively in the housing cover and especially in the screw channel.

In a further development of the invention, the housing and the housing cover made of electrically conductive material and the fastening screw causes an electrical contacting of the housing cover and housing with the shield surfaces of the circuit boards.

The mounting screw is in the assembled state on the one hand on the support surface at the lower end of the screw channel and sits on the other hand in a thread on the housing. As a result, a reliable electrical contact between the housing cover and housing is achieved, which in turn is crucial for the shielding of the data technology connection box.

In a further development of the invention, the housing and the housing cover in two, rotated by 180 ° positions are fastened to each other.

In this way, the flexibility of the data technology connection box according to the invention is further increased.

In a further development of the invention, the housing on its, the housing cover facing away from underside a through hole for insertion of cables and a through opening closing lid, wherein the underside of the housing and an underside facing the inside of the lid at least partially protrusions and / or have recesses for engaging the cables in order to provide a security for the cables in the closed state of the lid.

By simply placing and closing the cable passage opening closing lid can be achieved by a Zugsicherung for the cable. At the same time a shielding and contacting of the screen of the data cable can be achieved via an electrically conductive housing and / or an electrically conductive cover.

In a further development of the invention, the lid is arranged foldable on the housing.

In this way, the lid can be mounted in a particularly simple manner and data cables of different thickness can be secured between the lid and housing.

In a further development of the invention, the cover and / or the bottom of the housing is provided with an electrically conductive clamp, wherein the clamp comprises a braided shield of a cable over an angular range of 360 °.

The view of Fig. 1 The housing 12 is cup-shaped and has at its upper edge a circumferential support ring 17 with corner portions 16a, 16b, 16c, 16d and side portions 18a, 18b, respectively Through openings have to attach the data technology junction box 10 in different, standardized wall boxes or device cups or the like. The corner portions 16a, 16b, 16c, 16d and the side portions 18a, 18b can be broken off if the available space does not allow their placement or if only the through holes in the support ring 17 are needed. The housing 12 and the cover 14 are made of electroconductive zinc die-casting and are in electrical communication with each other, as will be discussed. The housing 12 and the cover 14 largely shield the internals of the data technology connection box. Data cables 13 lead away from the junction box 10.

The data technology connection box 10 also has two sockets 20a, 20b, which are arranged obliquely under a hood in the lid 14. An insertion in the sockets 20a, 20b is about 45 ° obliquely from above. The sockets 20a, 20b are designed as RJ45 sockets, socket receptacles contacts are not shown for clarity. The data technology connection box 10 according to the invention makes it possible to replace one or both of the sockets 20a, 20b with sockets of a different type. If this is done, it may be necessary to replace the lid 14 with another lid adapted to the outer shape of the sockets then used. A bezel, not shown, may be mounted on the junction box 10 to cover the top of the junction box 10 and to optionally provide flaps over the receptacles 20a, 20b.

The presentation of the Fig. 2 shows the data technology junction box 10 with the housing cover 14. In Fig. 2 is the oblique arrangement of the two RJ45 sockets 20a, 20b clearly visible. The two sockets 20a, 20b are arranged side by side on each of a printed circuit board 22a, 22b, which in the illustration of Fig. 2 However, only sections are visible. Evident is a housing insert 24, which consists of non-conductive plastic, which is cup-shaped and has a central opening, which corresponds to the outer dimensions the two adjacent sockets 20a, 20b is adjusted. The housing insert 24 is slipped over the sockets 20 a, 20 b until it rests with its bottom of the pot on the circuit boards 22 a, 22 b and with its peripheral pot wall, in the representation of Fig. 2 can not be seen, extending between the edge of the circuit boards 22a, 22b and the inner wall of the housing 12.

The presentation of the Fig. 3 shows a structural unit of the housing cover 14, housing insert 24, the two sockets 20a, 20b, the circuit boards 22a, 22b, wherein in the illustration of Fig. 3 only the circuit board 22b can be seen in sections. The assembly of sockets 20a, 20b, printed circuit boards 22a, 22b, housing insert 24 and housing cover 14 can after loosening two screws 28, of which in Fig. 3 only one can be seen, are removed from the housing 12. The fastening screws 28 engage with their threads in matching mating thread on the housing 12 and thereby cause inter alia an electrically conductive connection of the housing 12 and the housing cover 14th

Below this unit is in the representation of Fig. 3 a terminal block 26 is shown, which is arranged in the housing 12 below the assembly described above. The terminal block 26 is provided with a total of sixteen terminals 30, see Fig. 4 . Fig. 5 , which are designed as so-called LSA connection terminals (soldering, screw-stripping-free technology). The LSA connection terminals 30 are arranged on plate-shaped contact components 32 and formed integrally with socket contacts 34. Each contact component 32 thus has the shape of a sheet metal plate on which on the one hand the LSA connection terminals 30 and on the other hand, the socket contacts 34 are formed. Each contact component 32 is inserted into a matching slot 36 in the terminal block 26. An extension 35 on each contact member 32 extends through a through hole in the terminal block 26 and can be caulked to hold the contact member 32 in the terminal block 26. The slots 36 intersect in the region of the connection terminals 30 with radially extending insertion slots 38 for inserting cable cores. By inserting a cable core into a respective insertion slot 38, the cable cores are placed, then pressed by means of a standard tool into the insertion slots 38 and thereby simultaneously stripped in the region of the terminals 30 and contacted. Each insertion slot 38 is provided with protruding into the interior of the respective slot 38 projections 39 which engage on both sides of the insulation of the respective cable core and thereby secure against slipping out of the insertion slot 38. A data cable to be laid is inserted from below into the through hole formed inside the annular terminal block 26. The cable cores are then bent radially outwards and can thereby be easily inserted into the respective insertion slots 38. However, this laying of the cable wires takes place when the terminal block 26 is arranged in the housing 12. In its position in the housing 12, the terminal block 26 is held by locking lugs 42, which can engage in matching openings 43 on the housing 12, see Fig. 16 ,

In the area of the contact bushes 34, the slots 36 intersect with insertion openings 37, the contact pins on the underside of the printed circuit boards 22 a, 22 b lead during insertion into the contact bushes 34.

A further description of the terminal block 26 is still in connection with the illustration of Fig. 12 ,

When pushing the assembly of housing cover 14, housing insert 24 and sockets 20a, 20b and printed circuit boards 22a, 22b on the terminal block 26 is by means of in Fig. 3 not shown Contact pins on the underside of the circuit boards 22a, 22b made an electrical connection between the contact sockets 34 on the contact members 32 and the female contacts in the sockets 20a, 20b. After pushing this assembly on the terminal block 26 so that an electrical contact between the ends of the cable cores of a data cable 13 and the female contacts in the sockets 20 a, 20 b is made.

According to the invention thus the sockets 20a, 20b and the terminals 30 are formed for the cable cores as separable components. This makes it possible on the one hand to first insert the cable wires in the terminals 30 in the terminal block 26, in which case, since the sockets 20 are not attached, more space is available and the handling is simplified. On the other hand, by the separation of sockets 20a, 20b and terminals 30 data technology junction boxes can be easily retrofitted and this can be done even if the data technology connection box 10 is already installed. Namely, the sockets 20a, 20b can be easily removed from the terminal block 26 and replaced with other sockets, for example. Finally, it is still possible to easily correct a possible misplacement of the terminal block 26, which is detected only after the measuring of the data technology connection box 10 by first the sockets 20a, 20b are deducted from the terminal block 26 and the laid on this cable cores , which are then again easily accessible, reissued. It is essential that the laying of the cable wires can already be done with built-in housing, for example, if the housing is already installed in a building wall. The terminal block 26 is held in the housing and does not need to be held by a technician extra.

In the presentation of the Fig. 6 the housing cover 14 and the housing insert 24 with the sockets 20a, 20b are shown in an exploded view. The housing cover 14 has on opposite sides U-bracket 44, which are pushed over locking lugs 46 on the housing insert 24, there latch and thus hold the housing insert 24 on the housing cover 14. The housing cover 14 is further supported by the underside of screw channels 48 on the housing insert 24, which are likewise arranged on two opposite sides of the housing cover 14. On a screw channel 48 follows along the circumference of the housing cover 14 to 90 °, a U-bracket 44, after another 90 ° again a screw channel 48 and then again a U-bracket 44. With the U-brackets 44 and resting on the housing insert 24 Bottoms of the screw channels 48, the housing cover 14 is thus stably secured to the housing insert 24.

The screw channels 48 serve to receive a respective fastening screw 28. The top of the housing cover 14 facing away from the end of each screw channel 48 is provided with a laterally open slot 50 into which the fastening screw 28 can be inserted. The slot 50 is open at the side. It is envisaged to introduce the fastening screw 28 laterally into the oblong hole and then caulk the lateral opening of the oblong hole 50, so that the fastening screw 28 is held captive, since in the caulked state the lateral opening is smaller than the outer diameter of the fastening screw and there the screw channel When caulking only projections 51 are bent toward each other to at least partially close the lateral opening of the slot 50. Both the diameter of the lower slot 50 and the diameter of a through hole 52 at the upper end of the screw channel 48 are smaller than the outer diameter of the screw head of the fastening screw 28. Since the fastening screw 28 in a thread engages the housing 12, thereby the housing cover 14 can be moved into the cup-shaped housing 12, whereby at the same time the housing insert 24 is moved in the direction of the terminal block 26 in the housing 12. As already discussed, this causes the contact pins on the underside of the printed circuit boards 22a, 22b to be moved into the mating contact sockets 34 in the terminal block 26. By fastening screws 28 thus simultaneously the lid 14 and the sockets 20 can be brought into their final position.

On the other hand, by unscrewing the fastening screw 28, the housing cover 14 can again be lifted off the housing 12 and, at the same time, since the housing cover 14 engages via the U-bolts 44 with the latching lugs 46 of the housing insert 24, and furthermore the printed circuit boards 22a, 22 b are fastened via latching lugs on the housing insert 24, the sockets 20 a, 20 b are removed again from the terminal block 26. Since the upper passage opening 52 in the housing cover 14 is smaller than the outer diameter of the screw head of the fastening screw 28, the screw head 28 sets when unscrewing to the contact surface, which surrounds the passage opening 52 on the underside, and on further rotation of the fastening screw, the housing cover 14 is then raised , A screwdriver is inserted through the through hole 52.

The presentation of the Fig. 7 shows the housing insert 24 with the sockets 20a, 20b from above.

The presentation of the Fig. 8 shows the housing insert 24 obliquely from below. Within the housing insert 24, the two circuit boards 22 a, 22 b are arranged on their in the representation of Fig. 8 invisible top carry the two sockets 20. Each of the circuit boards 22a, 22b is provided with a plurality, preferably eight, contact pins 54, which are intended to be inserted into the contact sockets 34. The contact sockets 34 are, as already explained and as in Fig. 5 can be seen arranged in the contact members 32, which in turn are arranged in the slots 36 of the terminal block 26. To compensate for positional tolerances of the contact pins 54, the contact members 32 are floatingly received in the slots 36.

The contact pins 54 are arranged adjacent to the outer periphery of the respective printed circuit board 22a, 22b annular section. The contact pins 54 are arranged in the region of the outer edge of the printed circuit boards 22a, 22b in order to ensure the greatest possible distance between the individual contact pins, in turn to reduce interactions between the individual contact pins during operation. The printed circuit boards 22a, 22b also have shielding connections, not shown, in order to bring about an electrical contact with the housing 12 and / or the housing cover 14.

Both the printed circuit board 22a and the printed circuit board 22b are circular-segment-shaped. Not shown interconnects connect the contact pins 54 with solder terminals 56, with which in turn the receptacle contacts of the sockets 20 are connected. These solder pads 56 or solder pins are covered in the assembled state with a Lötpinabdeckung 57 which is secured with expansion rivets in matching openings 55 a, 55 b.

In the presentation of the Fig. 8 It can be seen that the printed circuit boards 22a, 22b are arranged below locking lugs 58 on the housing insert 24. The latching lugs 58 hold the circuit boards 22a, 22b in their position on the bottom of the pot-like housing insert 24. Furthermore, webs 59 are provided in the housing insert 24, which are in the gap between the printed circuit boards 22a, 22b are arranged and hold this together with the locking lugs 58 in position. When the contact pins 54 are pulled out of the contact sockets in the terminal block 26, the detents 58 ensure that the circuit boards 22a, 22b remain in position on the housing insert 24. As already explained, the housing insert 24 is moved away from the terminal block 26 by unscrewing the fastening screws 28 and thereby the housing cover 14, the housing insert 24 connected to the housing cover 14 and finally also the printed circuit boards 22a, 22b and the contact pins 54 from the terminal block Move away.

The presentation of the Fig. 9 shows the housing insert 24. Good to see the cup-like design of the housing insert 24, wherein recesses 60 are provided in the circumferential pot wall. These recesses 60 are aligned in the assembled state with semicircular cylindrical recesses 62 in the terminal block 26, see Fig. 12 , Through the recesses 60 and in the recesses 62 protrude in the assembled state dome-like projections 64 of the housing 12, which in the illustration of Fig. 14 can be seen. These dome-like projections 64 are made of conductive material and extend as shown in FIG Fig. 12 can be seen, between adjacent contact pairs of terminals 30. The dome-shaped projections 64 thereby provide a shield of individual contact pairs to each other.

Wall sections 66 between the respective recesses 60 in the circumferential pot wall of the housing insert 24 are arranged in the assembled state between the respective radially outer ends of the insertion slot 38 and the inner wall of the housing 12. Since the open ends of the cable cores come to rest at the radially outer end of the insertion slots 38, the wall sections 66 ensure for electrically insulating the ends of the cable wires from the electrically conductive housing 12.

In Fig. 9 Further support projections 61 can be seen, which extend from the inside of the pot bottom from the bottom of the pot insert 24 away. On the support projections 61 are in the mounted state, the circuit boards 22a, 22b, which are thus held by means of the support projections 61, the webs 59 and the locking lugs 58 securely in the housing insert 24, see also Fig. 8 ,

The presentation of the Fig. 10 shows the printed circuit boards 22a, 22b with the sockets 20a, 20b in the pushed onto the terminal block 26 state. The contact pins 54 engage in this position in the contact socket 34 of the contact members 32 in the terminal block 26 a.

The presentation of the Fig. 11 shows the two circuit boards 22a, 22b with the contact pins 54 and the sockets 20. Good to see that the circuit boards 22a, 22b are formed point-symmetrical to each other. The printed circuit boards 22a, 22b each have a projecting end and a recessed end in the region of their outer circumference. By this arrangement, sufficient space for the arrangement of the respective contact pins 54 can be created in the region of the separating slot between the two circuit boards 22a, 22b. Overall cover both circuit boards 22a, 22b together the shape of a regular octagon, but the edges are curved in a circle-shaped outward and thus adapted to the shape of the inner wall of the housing. In Fig. 11 is a Spreizniet 57a of Lötpinabdeckung 57 to recognize, see also Fig. 8 ,

The presentation of the Fig. 12 shows again the terminal block 26. As already explained, a data cable through the inner Opening the annular terminal block 26 is inserted. The individual cable cores are then arranged extending radially from the cable core outwards and thereby automatically come to the correct position to insert them into the insertion slots 38. A total of 16 insertion slots 38 are provided for 16 cable cores. The cable cores are then individually pressed into the insertion slots 38 by means of a standard tool, whereby at the same time the terminals 30 cut through the insulation of the cable cores and contact them. The connection terminals 30 are part of a respective plate-shaped contact component 32 and a respective insertion slot 36 for a contact component 32 intersects in the region of a connection terminal 30 with a respective insertion slot 38, see also Fig. 5 ,

The contact members 32 are opposite to a terminal 30 also provided with female contacts 34. The insertion slot 36 intersects in the area of the socket contacts 36 with a respective insertion opening 37 in the terminal block 26.

Based on the presentation of the Fig. 12 and the presentation of the Fig. 14 It can be seen that the annular terminal block 26 can be inserted in different positions in the housing 12. These different positions are rotated about a central longitudinal axis of the annular terminal block 26 by 45 ° to each other. It is thus possible to adjust a desired orientation of the sockets 20a, 20b in a highly flexible manner by appropriate positioning of the terminal block 26 in the housing 12, wherein the different positions of the terminal block 26 in the housing 12 by the position of the projections 64 in the housing 12 and the position the recesses 62 are predetermined in the terminal block 26.

The presentation of the Fig. 13 shows the data technology connection box 10 from above. In the presentation of the Fig. 13 is good to see that the through holes 52 in the housing cover 14 have a smaller diameter than the heads of the mounting screws 28. When unscrewing the mounting screws 28, the heads therefore attach to contact surfaces on the underside of the housing cover 14 and move on further unscrewing the mounting screws 28th thereby the housing cover 14 from the pot-like housing 12 out. As already described, thereby also the sockets 20a, 20b are deducted from the terminal block 26. In the presentation of the Fig. 13 It can also be seen that the diameter of the passage openings 52 is large enough to push through a screwdriver for actuating the fastening screws 28.

In Fig. 13 Further, the basic shape of the housing 12 as a cylinder with the cross section of a regular octagon whose side edges are slightly curved outward to recognize.

The presentation of the Fig. 14 shows the housing 12 in a view from above. The housing 12 is designed as a pot-like overall and in the region of its pot bottom, a through hole 70 is provided for the insertion of cable cores. In the Fig. 14 clearly visible, dome-like projections 64 are each provided with an internal thread 72, which serves for receiving in each case a fastening screw 28. In the presentation of the Fig. 12 are not shown fastening screws, as is apparent from the explanations made above, but only two opposing fastening screws 28 are used, which, depending on the rotational position of the annular terminal block 26 relative to the housing 12, are inserted into opposite dome-like projections 64. After removing the sockets 20a, 20b and the housing cover 14 are located the fastening screws 28 are no longer in the threaded holes 72 of the housing 12th

The presentation of the Fig. 15 shows the housing 12 in a view obliquely from below. The passage opening 70 can be closed by means of a hinged lid 74, on his, in the Fig. 15 left side is received with a pivot 76 in a slot 78 which is formed by means of a fork-like projection. Two fork-like projections take in each one-sided open slot 78 a right or left pivot 76 of the lid 74, wherein in Fig. 15 only a pivot 76 can be seen. An open end of the respective slot 78 can be caulked to keep the pivot pin 76 in the slot 78. Alternatively, an open end of the slot is formed narrowed, so that the pivot can be introduced with a certain pressure in the slot, the pivot and thus the lid but then captive on the housing 12 is held. At the, the pivot 76 opposite side of the lid 74, a screw hole 80 is provided for inserting a fastening screw 81, with which the lid 74 is then attached to the housing 12. Alternatively, the cover 74 can be fastened from the inside of the housing 12, wherein a fastening screw then engages from the inside into a threaded bore 83 in the cover 74. The lid 74 can therefore be fixed either from the inside or from the outside.

Openings 43 at the peripheral edge between the bottom and wall of the housing 12 are provided for inserting a tool, for pushing back the locking lugs 42 and for pushing out the terminal block 26 from the housing 12.

The presentation of the Fig. 16 shows the formation of the housing 12 in the region of its underside. A contact surface 82 for data cables is channel-like formed and has a plurality of transverse to the longitudinal direction of the groove extending projections 84. After closing the lid 74, the data cables 13 lying in the grooves 82 are pressed against the projections 84, whereby they are secured against being pulled out. After closing the lid 74 so that a Zugsicherung the data cable 13 is ensured on the housing 12. A threaded hole 90 is aligned in the mounted state of the lid 74 with the screw hole 80 in the lid 74 and a second screw hole 92 is then aligned with the threaded hole 83 in the lid 83, so that the lid 74 can be attached either from the inside or from the outside.

The presentation of the Fig. 17 shows the lid 74 in a view from below. It can be seen that in an area in which the data cables are inserted, channel-shaped recesses 86 are provided, which are provided with projections 88 which extend transversely to the longitudinal direction of the channel-shaped recesses 86. After closing the lid 74 an inserted data cable 13 is thereby secured from above and from below by means of the projections 84 and 88 against pulling out. In the region of the channel-shaped recesses 86 and the channel-shaped recess 82, the outer insulation of a data cable is still present, so that the projections 88 and 84 can dig well into the relatively soft insulation material of this enclosure and thereby provide reliable Zugsicherung.

The lid 74 is further provided with a contact clip 90, which has two groove-shaped configured areas. This contact clip 90 is provided to contact the screen braid of the respective data cable and thereby provide a good electrical connection between the shield braid of the data cable, the cover 74 and the housing 12 and the housing cover 14. By the bent free ends of the contact clip 90, the screen braid of the respective data cable over an angular range of approximately 360 °, in particular more than 300 °, contacted.

The sectional sectional view of the Fig. 18 shows a terminal block 100 according to another embodiment of the invention. The terminal block 100 may be used instead of in the Fig. 3 and 5 shown terminal block 26, wherein hereinafter only the differences of the terminal block 100 of Fig. 18 to the terminal block 26 will be described. In the terminal block 100 are in the same manner as in the terminal block 26 of the Fig. 3 a total of 16 contact members 102 are used, wherein the contact members 102 of the in Fig. 4 shown contact components 32 differ only in the shape of an extension 104. The extension 104 of the contact member 102 has at its free end two barbs 106 formed on the opposite narrow sides. The barbs are sized so that they dig when inserting the extension 104 into a through hole 108 of the terminal block 100 in the side walls of the through hole. The terminal block 102 can thereby be inserted into the in Fig. 18 shift shown position in which the contact member 102 is completely received in the terminal block 100. In the opposite direction, in the presentation of the Fig. 18 So up, the contact member 102 can not move more or only with considerable effort and the risk of destruction of the contact member 102. This is because the barbs 106 only dig deeper into the side walls of this passage opening 108 in the attempt to move the extension 104 out of the passage opening 108 and thereby prevent the contact component 102 from moving backwards.

In this way it is ensured that the example in Fig. 8 shown printed circuit boards 22a, 22b with the contact pins 54 repeatedly can be brought into engagement with the contact members 102, without the risk that the contact members 102 move out of the recesses in the terminal block 100 when removing the printed circuit boards 22a, 22b. Opposite in the Fig. 3 to 5 illustrated embodiment of the terminal block 26 and the contact members 32, the provision of the barbs 106 has the advantage that the contact members 102 can be both inserted by a simple insertion movement into the wells of the terminal block 100 and fixed in the terminal block 100. A caulking is no longer necessary.

The presentation of the Fig. 19 shows in an enlarged view of the contact member 102. Good to see the extension 104 with the two, formed on the opposite narrow sides of the extension 104 barbs 106. The barbs 106 form a widened position of the extension 104, starting from the barbs 106 tapering his free end tapers. In this way, the insertion of the extension 104 in the through hole 108 can be substantially facilitated and when inserting the extension 104, this centered beyond even in the through hole 108th
