Abstract

The modular connector system has a base body strip (2) with recesses (4) for cable fibres (15,16) and contact elements (3), in connector modules (1). The contact elements are formed by insulation displacement clamp terminal contacts (3) with contact slits (8) for incoming cable wires (16) and with contact slits (9) for outgoing wires (15). They also have contacts (11) for connecting the overvoltage shunt magazine (6). These contacts (11) are fitted into the module (1) with recesses (4) for the terminal contacts (3) and with chamber (5) for the magazine (6). They are pressed by the cable wires (16) inserted in the base strip (12) and contact them.

Modular connection system

The innovation relates to a modular connection system, especially in end distributors for communications and data technology, consisting of a strip base body with receptacles for cable wires and contact elements, and connection modules.

A modular connection system from AT & T is already known, in which a strip base body without any contacts is provided, into which the

closing cable wires and are pressed into the connection modules, equipped with standard cutting contacts, over the cable wires using a tool in order to contact them (brochure from AT & T: ANIXTER STOCKS, The AT & T 110 Connector and Patch Panel Systems). The disadvantage here is that no contacts are used in the advantageous Sehneid clamp connection technology. Furthermore, there are no options for equipping the modules with protective devices and no earthing devices are provided.

A terminal block with overvoltage protection is already known from DE 39 17 270 Al. This terminal block has two rows of insulation displacement contacts for connecting insulated cable wires. The two rows of insulation displacement contacts are arranged on different sides of the terminal block. An insulation displacement contact in the first row is connected to an insulation displacement contact in the second row via a connecting element. The surge arrester magazine is arranged laterally approximately in the middle between the two rows of insulation displacement contacts.

The disadvantage of this terminal block is that the user has no options for variable wiring, since the terminal block is equipped with all contacts and the only option is to wire all or some of the connections. The user is often forced to act uneconomically if, for example, he only uses a double wire.

needed.

The aim of the innovation is therefore to create a modular connection system, particularly for terminal blocks in communications and data technology, using the advantages of the cutting-Klemio connection technology, which enables cost-effective , flexible adaptation to the required expansion stage in the terminal block and which provides protection and earthing devices.

The solution to this problem arises from the characterizing features of claim 1. By dividing the connection strip into a strip base body with the known contour of the insulation displacement connection strips and into connection modules with the known insulation displacement contacts, it is achieved that only the required expansion stage needs to be equipped with contact elements and surge arrester magazines, so that savings can be made with regard to both. The design of the connection modules is expediently carried out in two double-wire versions, but any other design can also be used. The design of the strip base body and the connection modules in the known type of Sehneid clamp connection technology opens up all the advantages of this technology. The cable wires can be easily positioned in the base body and cut to length using the multifunctional and universal Sehneid clamp connection technology application tool. On the connection module, this insertion tool presses the wires into the contact slots, the insulation is

and the conductor is pushed between the spring-loaded contact slots. The arrangement of a central device earth allows the elimination of an earthing bar and the direct contact of the surge arrester magazines to the device earth and to the connection modules.

The innovation is explained in more detail below using an example of a modular connection system for end distributors shown in the drawings, made up of connection modules for two double wires and a strip base body for ten double wires. Shown are:

and, from insulation displacement connection contacts 3. The base body 2 contains receptacles 4 for the Sehneid clamp connection contacts 3 _f chambers 5 for surge arrester magazines 6 (Fig.2,3) and openings 7 for test equipment not shown as well as slots 19.

The insulation displacement connection contacts 3 are formed from an insulation displacement contact slot 8 for incoming cable wires 16 and an insulation displacement contact slot 9 for outgoing cable wires 15 (Fig. 3) as well as a contact II for contacting the surge arrester magazine 6, which is connected in one piece to the contact slots 8, 9 via a web 10. The insulation displacement connection contacts 3 are inserted into the receptacles 4. The contacts 11 cut out of the contact plate 22 are guided through the slots 19 into the chamber 5 and there make contact with contact lugs 21 (Fig. 3) of the surge arrester magazines 6, which are placed behind the spring-loaded contacts 11.

Fig. 2 shows a modular connection system which is formed from a strip base body 12 for ten double wires with receptacles 4 for insulation displacement connection technology for introducing five connection modules 1, from five chambers 5 for receiving five surge arrester magazines 6, a receptacle 13 with insulation displacement contacts 17 for earth wires and the cable sheath contact line (not shown) as well as from a device earth 14.

The modular connection system can, for example, be integrated into a terminal distributor (not shown) of the communication

ten technology must be introduced.

The following steps are necessary for peeling:

The incoming cables are prepared and inserted into the end distributor. The incoming cable wires (Fig.3) are placed in the strip base body 12 using an insertion tool for insulation displacement connection technology. To connect the outgoing cable wires 15, the connection modules 1 are placed on the incoming cable wires according to an assignment plan.

16. The insulation displacement connection contacts 8 in the connection module 1 contact the cable wires 16 inserted in the strip base body 12. The outgoing cable wires 15 are positioned in the upper contact slot 9 of the Sehneid clamp connection contact 3 using a placement tool so that the electrical contact is established between the incoming and outgoing cable wires 16,15. The earth wire is also inserted into the Sehneid clamp contacts using a placement tool.

17 of the holder 13. To protect the respective line, surge arrester magazines 6 for each connection module 1 are inserted between the connected insulation displacement connection contacts 3 and the central device earth 14 in the chambers 5. Instead of the device earth 14, it is also possible to produce a version with a built-in earth bar 25 (Fig.4). In this case, the device earth 14 is contacted on the earth bar 14. The magazines 6 then contact the built-in earth bar.

In Figures 3 and 4, the respective section through the modular connection system according to Fig. 2 shows the position of a connection module 1 in the strip base body 12 and the position of the chamber 5 as well as a surge arrester magazine 6 inserted therein. Furthermore, an outgoing and an incoming cable wire 15, 16 in the insulation displacement connection contact 3 as well as the contact 11 for connecting the surge arrester magazine 6 to the central device earth 14 are shown* Each surge arrester magazine 6 is assigned to a connection module 1, in the embodiment to two double wires. The electrical connection to the insulation displacement contacts 3 is made via their contact 11 and via the contact tongue 21 stored in the surge arrester magazine 6. In the event of an overvoltage, the overvoltage is discharged via the contact 11 and the contact tongue 21 through the surge arrester via the device earth 14. The device earth 14 is inserted into holding ribs 18 on the bar base body 12 (Fig.2). The contact to the surge arrester magazine 6 is made via, for example, fork contacts 23, 24 in a magazine tap 20 (Fig.2). Alternatively, an earth rail 25 can be installed.
