Distributor connection module for telecommunication and data technology

The invention relates to a distributor connection module for the telecommunications and data technology according to the preamble of patent claim 1. Such a distributor connection module is known from the <patcit id="pcit0001" dnum="US6305950B1"><text>US-B1-6305950</text></patcit> known.

Common distributor connection modules for the communication and data technology comprise two rows of connection contacts, which are arranged at one end of a housing. Such a distributor connection module is, for example, shown in FIG<patcit id="pcit0002" dnum="DE2725551"><text>DE 27 25 551</text></patcit> known. The distribution terminal module includes a first series of terminal contacts on the cable side and, opposite thereto, a second series of terminal contacts on the jumper side, the contacts on the cable side being considered as input contacts and the contacts on the jumper side as output contacts even though the information flow may be reversed . Middle contacts are arranged between the rows, into which test or protective plugs can be inserted. An example of such protective plugs are 3- or 5-point surge protection modules or relay protection circuits. If such an overvoltage protection is then plugged into the middle contacts, this medium tap and, in some cases, also adjacent middle taps, are no longer accessible for test and test purposes, or the surge protection must be removed again for the test and test purposes so that contact does not take place during this time Are hedged.

From the <patcit id="pcit0003" dnum="DE10029649A1"><text>DE 100 29 649 A1</text></patcit> There is known a distribution terminal for telecommunications and data technology comprising a housing in which externally accessible input and output contacts are arranged for connecting leads or conductors, the housing being formed with a cavity in which functional elements are arranged between the input and output terminals Output contacts. The input and output contacts can either be arranged in the same end face of the housing or else on opposite end faces, the input contacts of the one end contact and the output contacts being assigned to the other end face. This ensures a clear separation between the cable and jumper side, whereby the individual wires or cables do not interfere with each other.

In the transmission network between the nodes in the remote network network, among other things, STM1 interfaces are used, which are connected to a plurality of transmitters and receivers, which are formed, for example, by electronic units, the transmission capacity being currently at 2 Mbit / s per channel.

The invention is therefore based on the technical problem of providing a user-friendly distribution terminal module for the telecommunications and data technology, in particular for use in transmission networks between the node points.

The solution to the technical problem results from the subject matter with the features of patent claim 1. Further advantageous embodiments of the invention result from the subclaims.

For this purpose, the output contacts are designed as two mutually opposing rows of plug connectors, at least two input contacts of the first row and at least two input contacts of the second row being connected to the output contacts of in each case one plug connector. In this way, four cores can be assigned to one channel, two cores for reception and two cores for sending data. On the output side, shunting via the plug connector is very simple, so that prefabricated cables can be used.

On the input side, the distribution port module is user-friendly because all cores can be allocated to receive data from the subscriber of a series of input contacts and all of the wires to transmit data from a subscriber of the other set of input contacts. Thereby, a clear separation of the transmission and reception mode prevails on the input side, similar to the conventional connection strips, via which two rows of connection contacts separate the system and jumper sides. The electrical connection of the associated input contacts of the first and second series to their common plug connector takes place via the at least one printed circuit board.

In a preferred embodiment of the invention, the input contacts of the first and second series are designed as insulation displacement contacts.

In a further preferred embodiment, the connectors are designed as RJ-45 jacks. In the case of embodiments where only four cores are assigned to a channel, only four contacts of the RJ-45 socket are correspondingly connected to the input contacts, for example, the contacts 3-6 are wired, while the contacts 1, 2, 7, 8 remain unconnected Numbering of contacts according to RJ-45).

According to the invention, the plug connectors are also arranged in two mutually opposite rows. In this case, the electrical connections between the input and output contacts must be partially crossed because two connectors from each connector must be routed to the first row and two leads to the second row of input contacts.

In a further preferred embodiment, therefore, two opposing printed circuit boards are arranged within the housing and are electrically connected to each other, the crossing taking place via the electrical connection. The electrical connection of the two circuit boards is preferably effected via a flat-band cable. In principle, however, other electrical connections, such as, for example, plug-in contacts, are also possible.

In a further preferred embodiment, functional and / or protective elements are arranged on the printed circuit board which are electrically connected between the input and output contacts, such as, for example, filter or amplifier circuits or overvoltage protection elements.

In a further preferred embodiment, the housing is designed in several parts, at least a part of the housing being made of metal. In addition to an appealing design, the metallic housing allows the direct configuration with at least one grounding clip, which is formed from the housing and can be connected to the printed circuit board via contact pads. Furthermore, the metal housing is designed with connecting elements for profile bars and / or rails.

Furthermore, separating contacts are assigned to the input contacts, a separate disconnecting contact being preferably assigned to one contact pair each for measuring and testing purposes. Instead of separating contacts, switching or connection contacts can also be used.

The invention is explained in more detail below with reference to a preferred exemplary embodiment.

In the <figref idrefs="f0001">FIG</figref> The distributor connection module 1 is illustrated in a possible environment within a remote network network. The distributor terminal module 1 comprises an input side E and an output side A, whereby the terms input and output side only serve for definition since the information flow takes place in both directions. On the input side E are several transmitting modules S₁-S_n And a plurality of receiving modules E₁-E_n Respectively. The transmitting and receiving modules are each designed, for example, for a transmission capacity of 2 MB / s and are designed as electronic units. The individual sending modules S1-Sn can also be combined in a superordinate transmission unit SE. The receiving modules E₁-E_n To a receiving unit EE. The connection between the transmitting and receiving units SE, EE takes place via conventional telecommunication cables FK, wherein, for example, one pair of wires is assigned to a module. An STM1 module in SDH technology is arranged on the output side A, whereby the connection between the output side A and the STM1 module takes place via prefabricated patch cables PK. In the distributor connection module 1, wire pairs of transmitting and receiving modules which are associated with a common channel are then combined and transferred as a "channel cable" to the STM1 module. On the input side E, a separation takes place according to the transmission and reception mode, which will be explained in more detail later on, while channel separation takes place on the output side. It should be noted here that the transmitting and receiving units SE, EE can also be configured together as an STM1 module, the distributor connection module 1 is thus arranged between two STM1 modules.

In the <figref idrefs="f0002">FIGS. 2 and 3</figref> The distributor connection 1 is shown in perspective. The distributor terminal module 1 comprises a first series of input contacts 10 and a second series of input contacts 20 which are arranged opposite one another. In the illustrated example, each row comprises sixteen insulation displacement contacts 11, 21 for connecting eight double wires. A first row of output contacts 30 and a second series of output contacts 40 are arranged on the opposite end side, four output contacts of a row in the form of an RJ-45 socket 31, 41 being combined as plug connectors. Thus, the distributor terminal module 1 comprises in each case thirty-two input contacts 10, 20 and output contacts 30, 40. Furthermore, the distributor terminal module 1 comprises two front parts 12, 22 which form part of the housing and surround the input contacts 10, The front parts 12, 22 are preferably made of plastic.

The output contacts 30, 40 are surrounded by two metallic side walls 32 and a metallic base plate 33, which together with the two front parts 12, 22 form the housing. The two side walls 32 can be screwed to the base plate 33. The two side walls 32 each comprise two connecting elements 34, via which the distributor connection module 1 can be snapped onto a profile bar system (not shown). The two front parts 12, 22 are connected to the base plate 33 via detents 35. Furthermore, the base plate 33 comprises four grounding clips 36, via which an electrical connection to contact pads on non-visible circuit boards can be produced. The input contacts 10, 20 are connected to the output contacts 30, 40 via these circuit boards. In this case, two input contacts 10 of the first row corresponding to a double row and input contacts 20 of the second row are electrically connected to the output contacts 30, 40 of an RJ-45 socket 31, 41 via the printed circuit boards. In this case, only wires are connected via the input contacts 10, via which data are transmitted to the STM1 module and, via the input contacts 20, only wires are connected via which data transmitted by the subscriber are transmitted. The four connected contacts of an RJ-45 socket 31, 41 are thus connected to two input contacts 10 of the first row and two input contacts 20 of the second row. If, for example, an RJ-45 socket 41 is to be connected to the associated input contacts 10, 20, the connection for the input contacts 20 can be nearly straight through, where the connection from the input contacts 10 in the housing must cross from the bottom to the top. Correspondingly, the ratios of the contacting of an RI-45 socket 31 are correspondingly reversed. This crossing is preferably effected by two opposing printed circuit boards within the housing, which will be explained in more detail below. As a result, the two transmission directions are arranged separately from one another on the input side.

On the output side, on the other hand, the integration of the output contacts assigned to a channel in a plug-in connector can be very easily and easily pre-configured with prefabricated cables. Since usually more frequently on the output side than on the input side, the connecting elements 34 can also be turned over so that the RJ-45 sockets 31, 41 are freely accessible after the profile bar has been snapped onto the profile rod. Of course, more or less than eight channels can be connected in a distributor connection module 1.

In the <figref idrefs="f0003">FIG</figref> A plan view of the distributor connection module 1 is shown. In this case, a separating contact 13 which is accessible from the outside is assigned to each associated pair of input contacts 10, 20, wherein, as regards the formation of the separating contact 13,<patcit id="pcit0004" dnum="DE10029649A1"><text>DE 100 29 649 A1</text></patcit> Can be referred to. At this point, it should be noted that the input contacts can also be designed with further contacts for connecting a shield. In this case, three insulation displacement contacts 11, 21 would each be assigned to a double conductor. Four RJ-45 sockets 31 are arranged on the side of the printed circuit board 50 facing the output side. The front part 12 is snapped onto the side of the printed circuit board 50 facing the input side with the insulation displacement contacts 11, the insulation displacement contacts formed with fork contacts being pushed onto contact pads on the printed circuit board 50. The input contacts are then connected to these contact pads via contact lines 16 (not shown) and / or directly to RJ-45 jacks 31.

In the <figref idrefs="f0004">FIG</figref> Are two circuit boards 50 according to FIG <figref idrefs="f0003">FIG</figref> , Which are connected to one another via a flat-band cable 17 at the contact points 16. Via the contact points 16 or the flat-band cable 17, eight input contacts 10 are looped onto the lower printed circuit board 50 and eight input contacts 20 on the upper printed circuit board 50.

The distributor terminal module 1 can be extended in modules, so that instead of the described two rows of input and output contacts, a plurality of rows can be arranged one above the other. In addition, more than four cores can be assigned to one connector.
