MAIN DISTRIBUTION

Connection strips provide cost-effective, quick, well-arranged, and high-quality connecting and transferring leads.

Application

The applications for specific solutions are presented at individual dimensional groups of the strips.

Advantages of front-end arranged pins

Quick search for connection lines, and quick connectingWiring diagram repeated periodically by columnsQuick visual connection checking with adherence to wire colour coding Protection against contact, (identification strips cover the connecting pins and the accidental contact is avoided in this way).

Construction description

In the sheet metal grounded sub-racks there are functional inserts (with pins) alternatively inserted and fixed one after another and inserts with channels to lead wires. This separated solution with small sets of pins in functional inserts makes it possible to replace, if necessary, the entire insert; it restricts the confusion of cable cores or that of cross-connecting wires. The functional inserts are located in one direction and this position can be checked through their identification points. The cable cores are divided using a cross-connecting comb.

It is not necessary to tie the wires before the connection point – it results in quicker switching. When it is necessary to replace an insert, the disconnected cores are ready for reconnecting. Colour-coded identification covers, identification strips, legend plates, and elements define and clearly identify the connecting section.

Inserts

The cut-in pins in this functional inserts are arranged in two parallel rows with 10 or 8 pins each. Cable lines are connected to one of the rows while the other is used for cross-connecting lines.

Based on the structural design of the insert and the pin, the former can be used as follows:

1. The insert with disconnecting contacts:

This sort of insert has a dual four-way NC contact made of a noble metal between the pin on the cable side and the internal leads. This contact can be disconnected using the disconnecting pin. The cable side is then disconnected from the internal one.

Using suitable connecting leads, the external and internal lines can be connected to test instruments separately.
The colour of this insert is grey.

2. The insert with disconnecting contacts and protective discharge arresters:

The insert combines the already described qualities of the functional insert with the additional equipment for attaching the insert for discharge arresters.
To divert surge from the external lines, the cable section of each disconnecting contact is extended backwards, creating connecting points on the rear side of the appropriate insert for another insert to hold the protective discharge arresters. This insert can be inserted, easily and without interruption of the operation, in the functional insert. All the lines connected to this insert are protected against surge. The surge guard does not interfere with the operation of the insert with disconnecting contacts.
The colour of this insert is grey.

Both types of insert can be implemented if deep sub-racks and the appropriately deep functional inserts for protection against surge are used along with the integrated inserts with discharge arresters filled with inert gas and equipped with a fuse ring. The operation of equipment is not interrupted after this insert is connected or after it is operated on. Each cable pin has its own discharge arrester and fuse ring. The surge protection does not interfere with any eventual disconnecting or testing. For disconnecting strips, it is possible, when necessary, to apply current protection pins FK 021 63 to FK 021 67 with current rating 62 to 500 mA along with protection of both wires in the subscriber’s line.

3. Interconnecting insert

There is no electrical connection between the opposite pin rows. The connected lines can be brought out and hooked up using test adapters and leads.
The colour of this insert is blue.
