Description

IMPROVEMENTS IN BROADBAND FILTER INSTALLATIONS AND CONNECTIONS

There are several operators in the communications sector that provide voice transmission services to different users or consumers and require complex telephone networks related to many electrical, mechanical, and other components that can provide the services.

In particular, a switching exchange for providing various signals and lines for voice service in the telephone network, wherein the lines connected to the respective horizontal and vertical splitters by long cable arrangement distribute and operate the telephone lines, Can use the telephone network.

A wideband digital line connection multiplexer is provided that receives voice signals from a horizontal distributor and wideband signals from corresponding servers, such as an internet server, when video as well as voice, as well as data, are transmitted by the same operator. . The multiplexer is implemented as a filter or divider that can be divided once again into vertical dividers for combining the two signals and sending it to the user. Before this signal is received by the user, additional filters or dividers are provided that separate the two signals providing the voice line and the broadband line.

In accordance with recent regulation techniques, networks of distances known as customer loops have been formed so that they can be shared by other operators. That is, the second operator must form a system similar to the system used by the same operator, using a cable arranged on the distance belonging to the first operator.

Once the second operator is formed, the operator can receive independently the voice signal provided by the first operator and the broadband signal received directly from the broadband server to the second operator, and has its own general purpose architecture, distributors, In order to be able to provide the same service to the user using filters or the like, the same function as previously provided to the first operator should be performed.

Indeed, more specifically, these dividers are placed in large cabinets with identical frames and have printed circuits with identical electrical components such as transformers, inductors, capacitors, resistors, connectors, etc., which can filter the input signals according to the desired output. It is fixed to the cards.

Specifically, as shown in FIG. 1, in the prior art the cards 1 comprise a card edge connector 2 with normally open contacts, which are located on the rear part of the frames 5 via the printed circuit board 3. It is connected to the other connector 4, all of which are located in the divider area. In the rear region of the frames 5, the other connector 6 and the cable 7 are connected to corresponding distributors which are provided with conventional connection parts which are open or closed.

As mentioned above, since the card edge connector 2 has normal open contacts, its operation is similar to that of open contact portions that allow connection of data signals separately from normal voice signals. The disadvantage is that in the event of a fault required to repair the card, although there are no voice or data input signals available until the card 1 is replaced with a new one for repair, the user can operate it for a short time. It is not.

Also, since the cards used always contain one or more filters, i.e. there are cards with "n + 1" filters, at least n + 1 filter cards are installed for a single user who needs a signal, so that more Finance and material costs can be incurred by having n filters not used until users come in.

Furthermore, if one of the filters malfunctions and is used by more than one user, it may not be possible to service other users until repaired, and the entire board may have to be removed, or the second boards may be used at some cost. do.

Large size cabinets including filter circuits and their connections mean that certain areas must be provided as a large cubicle that is always removed from the distribution area, resulting in a cost increase due to the land area required for materials, wiring and the like.

The present invention is directed to many improvements of broadband filter devices and connections used in the communications field.

More specifically, the improvements are applicable to telephone networks used by different operators that provide transmission services to different users or consumers, and can greatly simplify circuit connections at the level of the broadband filters. Through the volume reduction of the cabinets holding the circuit and the final volume reduction of the cubicle containing the cabinets, the connection of broadband filters in any area for distribution frames can provide for distribution and operation of telephone lines.

The above and further features of the present invention will become apparent with reference to the accompanying drawings of preferred embodiments, the following figures being shown for illustrative purposes only:

1 is a conceptual diagram illustrating a prior art for connection of broadband filters.

2 shows a means similar to that of FIG. 1 with connections carried out according to the invention.

3 is an enlarged cross-sectional view showing one of the contacts of the connection portions that can be used in accordance with the present invention for connecting the filters directly to the system wiring without inserting printed circuit boards.

4 is a conceptual diagram illustrating one of the individual filter boards as disclosed by the present invention.

Figure 5 is a perspective view of one type of communication connector portion for use in accordance with the present invention.

Improvements of the present invention are primarily to simplify the device and connections in the areas provided for broadband filters or dividers, thereby saving cost and space.

More specifically for this purpose, one of the improvements of the present invention is the configuration of removing the open contact card edge connector, the above-described printed circuit board and the connections by performing filter connections alone through the connection portions. This means great simplification of the device and requires only a very simple rear frame to support the connections, thus reducing the occupied space and adjoining the intermediate bands before the voice band distribution frames used to distribute and operate the telephone lines. Filters may be installed in the areas used for the distribution frames.

The use of the communication connector portion in accordance with the present invention allows the use of separate filter boards for each user and can be extracted for repair in the event of a fault without leaving the remaining users without broadband service.

All of these may add to connecting the individual filter boards to the connections in the areas used for voice band distribution frames by installing a subtracted outer ring on the board itself.

In contrast to the conventional connection of the filters shown in FIG. 1 described above, according to one of the improvements of the invention, the filter card 1 ′ is preferably provided by a single connector part 8 of the type shown in FIG. 5. It is connected to the corresponding connection cable (7).

As will be apparent from the comparison of Figures 1 and 2, the present invention not only eliminates the card edge connector 2, but also the conventional printed circuit board 3 and its supplemental connectors 4,6. It is possible to remove it and replace the frame 5 with an extremely smaller frame 5 '. That is, through the advantage of the simplification of these connections, not only many connectors but also the large frames required to accommodate conventional filters can be eliminated, thereby reducing manufacturing and material costs, and providing a rear frame for attaching the connector portion ( Only 5 ') is required, which greatly reduces the space required and can be installed in the areas used for adjacent distribution frames before voice band distribution frames.

As shown in FIG. 3, the connector portion 8 has contact pairs 9, each of which can be received between them, electrically connected to the contacts of one of the filter boards, an arrow ( When there is an error of the data signal indicated by 10), the filter board can be sufficiently extracted without disturbing adjacent filter boards. As shown in this example, the closed contacts 9 establish a connection between the input 11 of the voice signal for the user and the corresponding output 12 when the filter board is extracted in order not to leave the user without the voice signal service. I can keep it.

As shown in Fig. 4, the filter board 1 on which the filter unit 13 is loaded is inserted between one of the plurality of contact pairs of the connector portion 8 ', which installs many individual filter boards 1'. May be repeated in other contact pairs to That is, one filter board for each user can be extracted separately for repair in error or unexpected events without leaving other users without broadband service.

Input and output signal wires (not shown) for each such filter board are connected to the connection members 21, 21 at opposite ends of the cavities 22, which are connected between opposite sides of the exemplary connector portion shown in FIG. 5. ') Can be inserted between each. Contact portions of the filter boards may be inserted between the respective contacts of the cavities 22 to be electrically connected to the input and output wires.

A simple wiring 14 is provided on the board 1 'to facilitate the connection of the individual filter boards 1' with other connector parts housed in the system area for voice band distribution frames.
