Description

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

The Requirements for data technology junction boxes are in the past Years constantly increased as more and more data transfer should be. To meet these increased demands with the well-known Coping with data technology junction boxes to be able to Numerous efforts are needed, which aim at crosstalk between cable cores and in particular contact pairs possible largely avoided. As further example, in so-called RJ45 sockets up to eight cable cores per socket Need to become and usually two RJ45 sockets arranged in a data technology junction box are, there is very little space for hanging up then overall 16 cable wires available. The laying of the cable wires is therefore tedious and time consuming. Finally are known data technology junction boxes little flexible in terms of the orientation of the ordered sockets in it, as it for example not readily possible is, the plug in the sockets differently choose.

With The invention is a flexibly applicable and easy-to-connect data technology connection box be created.

According to the invention is this a data technology junction box with a terminal block with terminals for laying cable wires, with at least a socket with receptacle contacts for contacting Data cable plugs and means for electrically connecting the terminals and the socket contacts provided, in which the means for electrical connection of terminals and socket contacts releasable Connectors have.

On this way you can the at least one socket and the terminal block independent of Laying the cable wires are disconnected. This facilitates the installation the data technology junction box Significantly, and in particular the laying of the cable wires is clear simplified. About that In addition, a flexible structure is achieved because the sockets without change of the terminal block can be changed. For example, the Data technology connection socket by simply replacing the socket be converted to different types of sockets. As connection terminals are advantageously terminals with LSA technology, ie soldering, screwing and stripping-free technology.

In Development of the invention, the terminals are annular in the terminal block arranged.

On this way can for Each of the terminals will be made more space available than this in a straight line arrangement of the terminals next to each other Case is. The annular Arrangement of the terminals can also be particularly favorable Way matched to the round basic shape of data technology junction boxes arising from the requirement, data technology junction boxes to install in standardized wall boxes. The annular arrangement allows doing so, without exceeding the given installation space, a maximum Distance between the terminals for each cable core too choose, so that possible Interactions between the cable cores are largely avoided can.

In Further development of the invention, the terminals are annular order a passage opening arranged in the terminal block around.

These measure makes it easier to hang up the cable cores considerably. After stripping a data cable, the individual cable wires are manually from each other moved away, leaving a star-like configuration of the then fanned out cable cores results. Between two cable cores is thereby a V-like gap locked in. thus fanned Data cables can in a particularly simple manner arranged in a ring around a passage opening Terminals are inserted, the data cable through the Through opening introduced becomes.

In Development of the invention, the terminal block is annular, in particular annular, formed.

A Such an embodiment of the terminal block on the one hand a maximum possible Distance between the individual cable wires is available on the other hand optimally to the round basic form of data technology junction boxes adjusted and finally facilitates the laying of the cable wires considerably.

In Further development of the invention, a housing is provided and the annular terminal block is in several positions rotated about its central axis in the casing used.

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

In Development of the invention, the connectors for electrical Connecting Terminals and Socket Contacts Contact pins and contact sockets, each with a terminal and a Contact socket or a contact pin integrated into a one-piece contact component are.

On This way results in a simple structure and by integrating in each case one connection terminal, in particular an LSA connection terminal, and a contact socket or a contact pin in a one-piece contact component can on this contact component transmission losses through contact resistance even do not arise first.

In Further development of the invention is the contact component as a plate-like Sheet metal part formed.

On This way results in a simpler and cheaper Construction. The plate-like contact components are for example in the terminal block can be inserted.

In Further development of the invention are the terminal and the contact socket or the contact pin on the contact component arranged side by side and arranged accessible from the same side of the terminal block.

The Place the cable wires in the individual terminals and the Inserting the sockets thus takes place from the same side of the terminal block forth, advantageously from above, so from one of the cable feed opposite Side. Through these measures is comparatively much space to hang up the cable and available if, after measuring the socket, an occupancy error is detected will, can the sockets are removed again and possibly a faulty Terminal block assignment can be corrected.

In Further development of the invention is the annular terminal block provided with receiving slots for insertion of the contact components, wherein the receiving slots intersect in the area of the terminals with cable core slots.

By these measures can the cable wires during insertion into the terminals through the insertion slots. The annular Terminal block is designed so that the cable cores be inserted into the terminals with a standard tool can.

In Further development of the invention is the terminal block with receiving slots provided for insertion of the contact components, wherein the receiving slots intersect with insertion openings in the area of the contact bushes.

On that way to realize a space-saving and structurally simple construction.

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

through such dome-shaped projections, the component of the existing of electrically conductive material casing can, a shielding effect between adjacent contact or Kabeladerpaaren be achieved. This allows trouble-free transmission with high transmission frequencies.

In Further development of the invention, the contact components are subject to play or floating in the terminal block.

The Contact components are advantageously floating parallel to the ring plane of the annular Terminal block recorded. This will make it possible for that Dodge the contact components laterally to a limited extent and thereby position tolerances of the contact pins or contact sockets, the on the side of the sockets are arranged, compensate. As eventual Bearing tolerances of the contacts balanced on the side of the sockets can be can be a reliable one Contact between the contact components on the side of the terminal block and the contacts on the side of the sockets are ensured. The contact components can For example, have an extension which extends through an opening in Terminal block extends through and caulked on the opposite side is.

In Further development of the invention is the terminal block with locking elements for latching to a housing Mistake.

For example, locking lugs or spring arms are on the outside of the annular terminal block arranged, which engage 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 Further development of the invention is the at least one socket arranged on a printed circuit board, on its, the socket facing away from contact sockets or pins.

A Such printed circuit board can with their contact pins or contact sockets then inserted in a particularly simple manner in the terminal block become. This is a separation of sockets and terminals possible, which, as already mentioned was, on the one hand facilitates the laying of the cable wires and the others a very flexible use of the data technology connection box according to the invention allows.

In Development of the invention, at least two sockets are provided, in each case a socket disposed on a separate circuit board is.

A such training increases the flexibility of inventive data technology junction box further. For example, on a left circuit board, an RJ45 socket be arranged on the right circuit board, however, a standardized telephone connection socket. Because the sockets and the terminal block can be separated from each other, This socket assignment can be changed at any time. This change of Socket assignment requires no change to the terminal block and specifically the inevitable short cut cable wires not in a terminal block again be inserted.

In Further development of the invention, the circuit boards are each as circular sections shaped.

On This way, optimum space utilization is achieved because the printed circuit boards adapted to the round basic shape of the data technology junction box are.

In Development of the invention take the circuit boards together one to the diameter of the annular Terminal block adapted shape. The contact pins or Contact sockets can annular in the edge region of the circuit board or circular section in the Be arranged edge region of the circuit boards.

The annular Arrangement of the contact pins or contact bushes is advantageously carried out with one as possible huge Diameter to adjacent pins as far as possible from each other spacing. The annular Design of the terminal block allows this large distance between the individual contact pins or contact sockets largely and only in the field of cable wires itself is the Distance of the individual signal paths then significantly reduced again. These measures contribute overall to a very good frequency response of the data technology connection box according to the invention.

In Development of the invention is the at least one socket, having the contact pins or contact sockets attached to a Gehäusein set, in a housing insertable and is designed to be pushed onto the terminal block, wherein the housing insert and the terminal block by means of at least one fastening screw are movable towards each other, wherein the fastening screw in parallel to the direction, in the housing insert with the at least one socket and the pins or Contact sockets can be pushed onto the terminal block.

By these measures can the sockets by simply pushing on the terminal block mechanically and electrically connected to this. Postponing takes place, for example, manually and the end position is then achieved by tightening the mounting screw. The fixing screw with its head advantageously prints the housing insert in the direction of the terminal block and sits with its opposite End either in the terminal block or, as in accordance with the invention is preferred in a thread in the housing.

In Further development of the invention, the housing insert and the at least a socket over Locking means connectable to each other.

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

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

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 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 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.

By doing the housing insert surrounding the terminal block laterally at least in sections, can be an insulation of the terminal block in the lateral direction against the case be achieved. The housing insert is made of electrically non-conductive material, the housing is made of electrically conductive Material manufactured, for example from zinc die casting. The housing insert can the terminal block at least in the areas laterally against the case isolate in which the individual laid cable wires radial with their uninsulated cable ends in the terminal block. When laying the cable wires on the terminal block the ends of the cable cores are substantially flush with the outer wall of the terminal block cut off. But it can not avoid the open, uninsulated cable ends slightly above an outer boundary of the Protruding terminal block. At least in these areas surrounds the circumferential pot wall of the housing insert the terminal block laterally to isolate the open cable wire ends against the electrically conductive housing.

In Further development of the invention is the circuit board in the pot-like housing insert inserted and by means of locking lugs on the inside of the pot wall attached.

Thereby can on the one hand a secure fixation of the circuit board in the housing insert and on the other hand, an electrical insulation of the circuit board be achieved.

In Further development of the invention is the housing insert with a housing cover connectable and the housing cover is by means of at least one fastening screw parallel to the Aufschieberichtung the contact pins or contact sockets of the at least one socket Movable away from the terminal block.

On This way, the at least one socket by means of the fastening screw be removed from the terminal block. Advantageously, serves the fixing screw at the same time, the at least one Socket together with the housing insert to move to the terminal block. Conveniently, two fastening screws are provided, for example, the right and left of at least one socket are arranged. By Screwing in the fastening screws can then open the socket move the terminal block until the fully inserted Position is reached. By unscrewing these two fixing screws the at least one socket can then again from the terminal block solved become. The socket is doing together with the housing insert emotional. When unscrewing supports the screw head of the fastening screw is at the bottom of the housing cover off, causing the housing cover is moved away from the terminal block and, since this with the housing insert is also connected, the housing insert together with the at least one socket from the terminal block moved away.

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

On this way it is possible with a tool, such as a screwdriver, on the To attack the head of the fixing screw and the fixing screw Turn it out until its head is at the edge of the passageway in the housing cover is applied. By further unscrewing the fastening screw is the housing cover then moved together with the screw head, namely from the terminal block path. The fastening screw supports advantageously in a thread in the housing. Because the terminal block but on the case is held by means of locking means, the housing cover from the terminal block be moved away while the housing insert and the at least take a socket with the pins or contact sockets.

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

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

In Further development of the invention is a distance between a contact surface for the head the fixing screw on the bottom of the housing cover and one thereof spaced apart in the direction of the housing insert bearing surface for the head the fastening screw shorter as the length of the Fixing screw. For example, on the housing cover one to the outer circumference of the housing cover open slot provided, in which the fastening screw introduced can be. The opposite Boundary sections at the open end of the slot can thereby be designed so that they are after inserting the fixing screw can be caulked and thereby hold the mounting screw captive, since the after caulking still existing slot opening of the slot narrower as the outer diameter the fixing screw is. Alternatively, the distance is sized that the fastening screw obliquely between the contact surface on the Bottom of the housing cover and the bearing surface spaced therefrom can be inserted. The fixing screw can thereby obliquely between housing insert and housing cover introduced are the distance between contact surface and support surface but then so small that the fixing screw for both the peeling as well as the pressing the at least one socket from the terminal block or can be used in the direction of the terminal block.

In Development of the invention is below the contact surface on the Bottom of the housing cover arranged a laterally open screw channel whose clear width is larger as the diameter of the screw head of the fastening screw and on the contact surface opposite End the support surface for the Head of the fastening screw is arranged.

Conveniently, are on opposite Sides of the housing cover two such screw channels arranged. The contact surface surrounds the passage opening in the housing cover and the screwdriver is inserted through the through hole. A connection between housing cover and housing insert is effected by a latching connection. The fixing screw but is exclusive in the housing cover and especially in the screw channel.

In Development of the invention consist of the housing and the housing cover made of electrically conductive Material and the fastening screw causes an electrical contact from housing cover and housing with the screen surfaces the circuit boards.

The Mounting screw is in the assembled state on the one hand the bearing surface at the lower end of the screw channel and sitting on the other hand in a thread on the housing. This will be a reliable one achieved electrical contact between housing cover and housing, in turn for the shielding of the data technology junction box of crucial Meaning is.

In Development of the invention, the housing and the housing cover in two, twisted by 180 ° Positions attachable to each other.

On this way, the flexibility the data technology connection box according to the invention further increased.

The corner sections 16a . 16b . 16c . 16d and the side sections 18a . 18b can be canceled if the available space does not allow their accommodation or if only the through holes in the support ring 17 needed. The housing 12 and the lid 14 are made of electrically conductive diecast zinc and are electrically connected to each other, as will be discussed. The housing 12 and the lid 14 shield the internals of the data technology junction box largely from. data cable 13 lead from the junction box 10 path.

The data technology junction box 10 also has two sockets 20a . 20b up, diagonally under a hood in the lid 14 are arranged. One plug in the sockets 20a . 20b is about 45 ° from diagonally above. The sockets 20a . 20b are designed as RJ45 sockets, socket receptacles contacts are not shown for clarity. The inventive data technology connection box 10 allows one or both of the sockets 20a . 20b replace with sockets of other types. If this happens, the lid may need to be replaced 14 be replaced with another lid, which is adapted to the outer shape of the then used sockets. An unillustrated panel can on the junction box 10 be attached to the top of the junction box 10 cover and possibly flaps over the sockets 20a . 20b provide.

The presentation of the 2 shows the data technology junction box 10 with removed housing cover 14 , In 2 is the oblique arrangement of the two RJ45 sockets 20a . 20b clearly visible. The two sockets 20a . 20b are next to each other on each of a circuit board 22a . 22b arranged in the representation of the 2 However, only sections are visible. To recognize is a housing insert 24 , which consists of non-conductive plastic, which is cup-shaped and has a central opening, the conditions of the Außenabmessun the two adjacent sockets 20a . 20b is adjusted. The housing insert 24 is via the sockets 20a . 20b slipped up, with his bottom of the pot on the circuit boards 22a . 22b abuts and with its peripheral pot wall, which in the representation of 2 It can not be seen, between the edge of the circuit boards 22a . 22b and the inner wall of the housing 12 extends.

The presentation of the 3 shows a unit of housing cover 14 , Housing insert 24 , the two sockets 20a . 20b , the circuit boards 22a . 22b , in the representation of the 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 fixing screws 28 of which in 3 only one can be seen, from the housing 12 be removed. The fixing screws 28 grip with their thread in matching mating thread on the housing 12 and thereby cause inter alia an electrically conductive connection of housing 12 and housing cover 14 ,

Below this unit is in the representation of 3 a terminal block 26 shown in the housing 12 is arranged below the above-described unit. The terminal block 26 is with a total of sixteen terminals 30 provided, see 4 . 5 , which are designed as so-called LSA connection terminals (soldering, screw-stripping-free technology). The LSA terminals 30 are on plate-shaped contact components 32 arranged and integral with socket contacts 34 educated. Each contact component 32 thus has the shape of a sheet metal plate on which on the one hand, the LSA terminals 30 and on the other hand the socket contacts 34 are formed. Each contact component 32 is in a matching slot 36 in the terminal block 26 inserted. An extension 35 on each contact component 32 extends through a through hole in the terminal block 26 and can be caulked to the contact member 32 in the terminal block 26 to keep. The slots 36 intersect in the area of the terminals 30 with radial insertion slots 38 for inserting cable cores. By inserting a cable core into a respective insertion slot 38 The cable cores are placed, then by means of a standard tool in the insertion slots 38 pushed in and thereby simultaneously in the area of the terminals 30 stripped and contacted. Each insertion slot 38 is with in the interior of the respective slot 38 protruding projections 39 provided, which attack on both sides of the insulation of the respective cable core and this thereby against slipping out of the insertion slot 38 to back up. A data cable to be placed on the bottom of the inside of the annular terminal block 26 formed passage opening introduced. The cable cores are then bent radially outward and can thereby easily in the respective insertion slots 38 be inserted. This laying of the cable wires, however, takes place when the terminal block 26 in the case 12 is arranged. In his position in the case 12 becomes the terminal block 26 by latching noses 42 kept in matching openings 43 on the housing 12 can snap into place, see 16 ,

In the field of contact sockets 34 the slits intersect 36 with insertion openings 37 , the contact pins on the bottom of the circuit boards 22a . 22b when inserted into the contact sockets 34 to lead.

Another description of the terminal block 26 is still in connection with the presentation of the 12 ,

When sliding the assembly out of the housing cover 14 , Housing insert 24 as well as sockets 20a . 20b and printed circuit boards 22a . 22b on the terminal block 26 is by means of in 3 not shown pins on the underside of the circuit boards 22a . 22b an electrical connection between the contact sockets 34 at the contact components 32 and the socket contacts in the sockets 20a . 20b produced. After sliding this unit onto the terminal block 26 is thus an electrical contact between the ends of the cable cores of a data cable 13 and the socket contacts in the sockets 20a . 20b produced.

According to the invention thus the sockets 20a . 20b and the terminals 30 for the cable cores formed as separable components. This makes it possible, first, the cable wires in the terminals 30 in the terminal block 26 insert, in which case, since the sockets 20 not yet appropriate, more space is available and handling is simplified. On the other hand, through the doors plug sockets 20a . 20b and terminals 30 Data technology junction boxes can be easily retrofitted and this can be done even when the data technology junction box 10 already installed. The sockets 20a . 20b namely, can easily from the terminal block 26 deducted and replaced for example by other sockets. Finally, it is still possible, a possible misplacement of the terminal block 26 , which only after the Durchmessens of the data technology junction box 10 is detected, in a simple way to correct, by first the sockets 20a . 20b from the terminal block 26 be deducted and placed on these laid cable wires, 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 case and does not need to be held by a fitter extra.

In the presentation of the 6 are the housing cover 14 and the housing insert 24 with the sockets 20a . 20b shown in an exploded view. The housing cover 14 has U-bars on opposite sides 44 on, over the locking lugs 46 on the housing insert 24 be pushed there, and then engage the housing insert 24 on the housing cover 14 hold. The housing cover 14 continues to support itself with the underside of screw channels 48 on the housing insert 24 which also on two opposite sides of the housing cover 14 are arranged. On a screw channel 48 follows along the circumference of the housing cover 14 after 90 ° a U-bracket 44 , after another 90 ° again a screw channel 48 and then another U-hanger 44 , With the U-hangers 44 and on the case 24 resting undersides of the screw channels 48 is the housing cover 14 thus stable on the housing insert 24 secured.

The screw channels 48 each serve to receive a fixing screw 28 , The top of the housing cover 14 opposite end of each screw channel 48 is with a laterally open slot 50 provided, in which the fastening screw 28 can be introduced. The slot 50 is open at the side. It is provided, the fixing screw 28 Insert laterally into the slot and the side opening of the slot 50 then caulk so that the fixing 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 48 shorter than the entire length of the fastening screw 28 , When caulking only projections 51 bent on each other, around the lateral opening of the slot 50 at least partially close. Both the diameter of the lower slot 50 as well as 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 , Because the fixing screw 28 in a thread on the housing 12 engages, thereby the housing cover 14 in the cup-shaped housing 12 be moved in, thereby simultaneously the housing insert 24 towards the terminal block 26 in the case 12 to be moved. As already discussed, this will cause the contact pins on the underside of the circuit boards 22a . 22b in the appropriate contact sockets 34 in the terminal block 26 moved into it. Through the fixing screws 28 can thus simultaneously cover 14 and the sockets 20 be brought into their final position.

On the other hand, by unscrewing the fastening screw 28 also the housing cover 14 back from the case 12 can be lifted and at the same time thereby, since the housing cover 14 over the U-bolts 44 with the locking lugs 46 of the housing insert 24 engaged, and continue the circuit boards 22a . 22b via locking lugs on the housing insert 24 are fixed, the sockets 20a . 20b again from the terminal block 26 be removed. Because the upper through hole 52 in the housing cover 14 smaller than the outer diameter of the screw head of the fastening screw 28 the screw head settles 28 when unscrewing to the contact surface, the passage opening 52 on the underside of which surrounds, and on further rotation of the fastening screw is the housing cover 14 then raised. A screwdriver is doing through the through hole 52 through put.

The presentation of the 8th shows the housing insert 24 from diagonally below. Inside the housing insert 24 are the two printed circuit boards 22a . 22b arranged on their in the representation of the 8th invisible top the two sockets 20 wear. Each of the circuit boards 22a . 22b is with several, preferably eight, pins 54 provided, which are provided in the contact sockets 34 to be plugged. The contact sockets 34 are, as already explained and as in 5 can be seen in the contact components 32 arranged, in turn, in the slots 36 of the terminal block 26 are arranged. To position tolerances of the contact pins 54 compensate, are the contact components 32 floating in the slots 36 added.

The contact pins 54 are adjacent to the outer periphery of the respective circuit board 22a . 22b arranged circular ring section. The contact pins 54 be in the area of the outer edge of the circuit boards 22a . 22b arranged in order to ensure the largest possible distance between the individual pins, in turn to reduce interactions between the individual pins during operation. The circuit boards 22a . 22b have shield connections not shown further to an electrical contact with housing 12 and / or housing cover 14 to effect.

Both the circuit board 22a as well as the circuit board 22b are formed circular section. Not shown interconnects connect the pins 54 with solder joints 56 , with which in turn the socket contacts of the sockets 20 are connected. These solder joints 56 or solder pins are in the assembled state with a Lötpinabdeckung 57 covered with expanding rivets in matching openings 55a . 55b is attached.

In the presentation of the 8th it can be seen that the circuit boards 22a . 22b below locking lugs 58 on the housing insert 24 are arranged. The locking lugs 58 hold the circuit boards 22a . 22b in their position on the pot bottom of the pot-like housing insert 24 , Furthermore, in the housing insert 24 Stege 59 provided in the gap between the circuit boards 22a . 22b are arranged and this together with the locking lugs 58 hold in position.
