Title:

Connection device for CAT-5 cables

Description

The invention relates to a connection device for connecting to a cable end of a cable according to the CAT-5 standard, in particular with 8 lines, according to the preamble of claim 1.

Conventional CAT-5 cables only use a portion of the eight or four pairs of wires present in the cable. This leads to unused material in corresponding connection systems.

In the worst case scenario, 50% of the installed line capacity remains unused.

It is the object of the present invention to provide a connection device of the above-mentioned type which eliminates the above-mentioned disadvantages and with which it is possible to distribute the eight wires or conductors of a cable over sixteen contact pins in order to obtain two independent connections.

This object is achieved by a connecting device of the above-mentioned type with the features characterized in claim 1.

For this purpose, it is provided that the connection device has at least a first connection socket and a second connection socket with respective contact pins, wherein at least two, in particular four or eight lines of the cable are connected to the contact pins of the first connection socket and the remaining lines not occupied by the first connection socket are connected to the second connection socket, wherein the lines of the cable and the contact pins of the first and second connection sockets are provided with number and/or letter and/or color coding and wherein the lines are connected to the contact pins of the first connection socket with the order of the contact pins matching the order of the lines and the lines are connected to the contact pins of the second connection socket in an order that deviates from the order of the lines to the contact pins of the first connection socket.

so that unused lines from the first connection socket are available to the second connection socket.

This has the advantage that by using conventionally unused cable pairs of the CAT-5 cable, for example, two or more independent connections of the same or different services are available on a single CAT-5 cable.

This makes it possible to use them in pairs with twisted pair cabling (CAT5). Using the two unused pairs of conductors creates two independent connections for the same service. The pins are assigned either to PIN 1/2/7/8 and/or 3/4/5/6, whereby PIN 1/2/7/8 is used for example for

- IBM-3270 in conjunction with adapter RJ45/BNC (RG62) pin 1 &2 and PIN 3/4/5/6 e.g. for

- ISDN telephony/fax (PIN 3/4/5/6)
analogue telephony/fax a/b (PIN 4/5)

- IBM-3270 in conjunction with adapter RJ45/BNC (RG62) pin 4&5

- Token ring with adapter RJ45/Type1 (PIN 4/5/6/3).

Preferably further developments of the device are described in the subclaims.

To statistically eliminate crosstalk between different lines of the cable, it is advantageously designed as a twisted pair cable.

In a preferred embodiment, the connections of the lines of the cable with the contact pins of the connection sockets are designed such that at least one, in particular two of the connection sockets is or are an IBM 3270 connection, an analog telephony/fax connection, a token ring connection and/or an ISDN telephony/fax connection.

Depending on the intended use of the CAT-5 cable, the connection sockets comprise at least one, in particular two RJ-45 sockets, at least one, in particular two RJ-11 sockets and/or at least one, in particular two, three or four BNC sockets.

A particularly compact and reliable arrangement is achieved by arranging the connection sockets on a printed circuit board, on which a contact device is arranged for each connection socket for connecting line ends of the cable lines of the cable, with respective predetermined contacts of the contact devices being connected via the printed circuit board to respective predetermined contact pins of the respectively assigned connection socket.

The contact devices are expediently cutting and/or clamp contacts or are housed on a circuit board.

A corresponding immunity to interference radiation with a simultaneous low level of radiation from the connection device itself to the outside is achieved by arranging a shield in such a way that it surrounds the circuit board.

A connection arrangement that can be produced particularly cost-effectively and reliably is achieved in that all line ends of the cable lines of the cable are connected to a first contact device of the first connection socket and, for corresponding connections to one or more further contact devices of further connection sockets, respective lines run from corresponding contacts of the first contact device to corresponding contacts of the corresponding other contact device or devices.

The cable is expediently designed with a shield, which is connected to the additional shield contact pins of the connection sockets. A shield can also be omitted.

In a particularly preferred embodiment, the lines of the cable and the contact pins of the connection sockets are color-coded, with the lines or contact pins one to eight in this order having the color coding green/white, green, orange/white, blue, blue/white, orange, brown/white and brown.

For example, two independently usable IBM-3270 connections for example in conjunction with an RJ-45 or BNC adapter with RG 62 on, for example, green/white and green contact pins can be achieved by connecting the green/white, green, brown/white, brown lines to the green/white, green, brown/white, brown contact pins of the first connection socket and the orange/white, blue, blue/white, orange lines to the brown/white, green, green/white, brown contact pins of the second connection socket.

For example, two independently usable ISDN telephone connections can be achieved by connecting the orange/white, blue, blue/white, orange lines to the orange/white, blue, blue/white, orange contact pins of the first connection socket and the green/white, green, brown/white, brown lines to the blue/white, blue, orange/white, orange contact pins of the second connection socket.

The invention is explained in more detail below with reference to the accompanying drawings. These show

Fig. 8 shows another embodiment for the application of the connection device on four contact pins each of the two connection sockets, but with a different contact pin distribution compared to Fig. 7.

The embodiment shown in Fig. 1 to 3 shows a connection device 100, which comprises a housing 10 in which a circuit board 14 is fastened with screws 16 within a shield 12. On the circuit board 14 there is a first connection socket 18, a second connection socket 20, a first contact associated with the first connection socket 18.

• V ♦♦· · ♦· ··· ·

A clock device 22 and a second contact device 24 associated with the second termination socket 20 are arranged.

The connection device is connected to conductors 26 of a twisted pair cable 28, with respective ends of the conductors 26 being connected to contacts 30 and 32 of the first and second contact devices 22 and 24, respectively. Predetermined contacts 30 and 32 of the contact device 22 and 24, respectively, are connected to predetermined contact pins 34 and 36 of the connection sockets 18 and 20, respectively. As can be seen in particular from Fig. 3, corresponding conductor tracks 38 and 40 lead from all contacts 30 and 32, respectively, to corresponding contact pins 34 and 36, respectively. The contacts 30 and 32 are connected to corresponding contact pins 34 and 36, respectively.

The cable 28 has a shield conductor 44 which is connected to corresponding shield contact pins 46 and 48 of the connection sockets 18, 20.

In the embodiment shown as an example, all eight or four pairs of conductors 26 of the cable 28 are connected to the first contact device 22, which has corresponding eight contacts 30. From the contacts 30 that are not connected to contact pins 34 of the first connection socket 18 via conductor tracks 38, connecting wires 42 lead to corresponding contacts 32 of the second contact device 24, whereby these contacts 32 are connected to corresponding contact pins 36 of the second connection socket 20 via corresponding conductor tracks 40.

In this way, different connection configurations can be implemented according to the invention from the cable 28 to the connection sockets 18 and 20, with two possible connection configurations being shown as examples in Figs. 4 and 5. In Figs. 4 and 5, the same parts are designated with the same reference numbers as in Figs. 1 to 3, so that for a more detailed explanation, reference is made to the description of Figs. 1 to 3.

In both connection configurations according to Fig. 4 and 5, the shield 44 is connected to the shield contact pins 46 and 48 of the connection sockets 18 and 20 .

The wires of cable 28 and the contact pins of the connection sockets are each numbered 1 to 8 and additionally provided with a color code, whereby the wires or connection sockets one to eight are assigned the following color codes in this order: green/white, green, orange/white, blue, blue/white, orange, brown/white and brown.

With reference to Fig. 4, the following contact routing results on a circuit board between the eight or four pairs of lines 26 of the cable 28 with the first contact device 22 or the first connection socket 18 or its contact pins 34, which are individually designated with 34.1, 34.2, 34.3, 34.4, 34.5, 34.6, 34.7 and 34.8, whereby the individual pairs of lines 26 are designated with P1, P2, P3 and P4 and their individual conductors with L1, L2 of the pair P1, with L3, L6 of the pair P2, with L4, L5 of the pair

M «r

P3 and L7, L8 of the pair P4 are designated: the conductors L1, L2 are connected to the contact pins 34.1, 34.2, the conductors L3, L4 to the contact pins 34.3, 34.4, the conductors L5, L6 to the contact pins 34.5, 34.6 and the conductors L7, L8 to the contact pins 34.7, 34.8.

The contact pins 32 of the second connection socket 20 are individually designated with 36.1, 36.2, 36.3, 36.4, 36.5, 36.6, 36.7 and 36.8.

The conductors 26 of the cable 28 are, however, connected to the contact pins 36 of the second connection socket 20 as follows: the conductor L1 of the first pair P1 with the contact pin 36.5, the conductor L2 of the first pair P1 with the contact pin 36.4, the conductor L3 of the second pair P2 with the contact pin 36.7, the conductor L4 of the third pair P3 with the contact pin 36.2, the conductor L5 of the third pair P3 with the contact pin 36.1, the conductor L6 of the second pair P2 with the contact pin 36.8, the conductor L7 of the fourth pair P4 with the contact pin 36.3 and the conductor L8 of the fourth pair P4 with the contact pin 36.6. In this way, eight conductors of the cable 28 are distributed over sixteen contact pins of two connection sockets 18, 20. This division makes it possible to obtain two independent connections 18 and 20.

The connection device 100 is designed according to Fig. 4 so that the individual lines L1, L2; L3, L4; L5, L6, L7, L8 of the cable 28 are connected in the same order to the contact pins 34.1, 34.2, 34.3, 34.4, 34.5, 34.6, 34.7 and 34.8 of the first connection socket 18 and in unequal order.

sequence with the contact pins 36.1, 36.2, 36.3, 36.4, 36.5, 36.6, 36.7 and 36.8 of the second connection socket 20 such that the lines 26 of the cable 28 are assigned to the contact pins of the second connection socket 20 as follows:

Line (L1) -> contact pin (36.5)

Line (L2) -^ Contact pin (36.4)

Line (L3) -> contact pin (36.7)

Line (L4) -> contact pin (36.2)

Line (L5) -> contact pin (36.1)

Line (L6) -^ Contact pin (36.8)

Line (L7) -> contact pin (36.3)

Line (L8) -> contact pin (36.6),

so that the order of the connections of the lines of the cable 28 with the contact pins of the second connection socket 20 differs from the connection order of the contact pins of the first connection socket 18 with the lines of the cable 28, so that lines of the second connection socket that are not occupied by the first connection socket are available.

The connection device according to the invention provides two independent connections for one or more services using a single cable 28 in accordance with a so-called CAT-5 standard. Services

The following are to be understood here, for example: An IBM-3270 connection on contact pins 1/2/7/8, for example in connection with adapter RJ45 or BNC with RG62 on contact pins 1 and 2; an ISDN telephony connection on contact pins 3/4/5/6; an analogue telephony/fax connection a/b on contact pins 4/5; an IBM-3270 connection on contact pins 3/4/5/6, for example in connection with adapter RJ45 or BNC with RG 62 on contact pins 4 and 5; a token ring connection, for example with adapter RJ45/Type 1 on contact pins 4/5/6/3.

Fig. 5 and 6 show the top and bottom of a printed circuit board 14 with the connections of the conductors 26 of the cable 28 to the first and second connection sockets 18, 20.

Taking color coding into account, the following connection structure results:

The lines 26 green/white, green, orange/white, blue, blue/white, orange, brown/white, brown are connected to the contact pins 34 green/white, green, orange/white, blue, blue/white, orange, brown/white and brown of the first connection socket 18 (Fig. 6) and the lines green/white are connected to the contact pin blue/white, and green to the contact pin blue, and orange/white to the contact pin brown/white and blue to the contact pin green and blue/white to the contact pin green/white and orange to the contact pin brown and brown/white to the contact pin orange/white and brown to the contact pin orange of the second contact socket 20 (Fig. 5).

As can be seen from Fig. 5, the green/white and green lines, the orange/white and orange lines, the blue and blue/white lines and the brown/white and brown lines of the cable 28 are combined to form pairs P1, P2, P3, P4, with the pair P1 being connected to the blue and blue/white contact pins, the pair P2 to the brown/white and brown contact pins, the pair P3 to the green/white and green contact pins and the pair P4 to the orange/white and orange contact pins of the second connection socket.

Fig. 7 and 8 show further application examples of the invention. According to the connection configuration according to Fig. 7, the following connection structure results: The green/white line 26 is connected to the green/white contact pin, the green line to the green contact pin, the brown/white line to the brown/white contact pin and the brown line to the brown contact pin of the first connection socket 18 and the lines 26 not used by this are connected to the second connection socket 20 in such a way that the orange/white line is led to the brown/white contact pin, the blue line to the green contact pin, the blue/white line to the green/white contact pin and the orange line to the brown contact pin of the second connection socket 20. Example for IBM 3270.

The connection configuration shown in Fig. 8 is as follows: The orange/white line is connected to the orange/white contact pin, the blue line to the blue contact pin, the blue/white line to the blue/white contact pin and the orange line to the orange contact pin of the first

Connection socket 18 is connected, and the lines not used by this 26 with the second connection socket 20 are connected in such a way that the green/white lines are connected to the blue/white contact pin, the green line with the blue contact pin, the brown/white line with the orange/white contact pin and the brown line with the orange contact pin of the second connection socket 20. Example for ISDN telephone/fax.

In both of the above examples, the other end of the cable 28 is connected in a corresponding manner to a device or other cables in accordance with the CAT-5 standard. The two pairs of conductors that would not be used in accordance with the CAT-5 standard, conductors 3, 4, 5, 6 and conductors 1, 2, 7, 8, are used on the cable side in a manner deviating from the CAT-5 standard, but are connected correctly to the respective contact pins, so that when the respective conductors are connected in accordance with the standard to the second connection socket 20, an additional connection for the same service is created.
