Isolating plug for the isolating strip of telephone systems

Such isolating plugs are used to separate a fully connected power path on a so-called. Separating strip segment of a separating strip of, for example, telecommunications switching systems. Each of the sash segments There are matching plug openings. When the isolating plug is inserted into the desired plug opening is, it should shortly before and in its end position the contact springs of the segment of. its normally closed contacts lift up.

In the event of disconnections or cable malfunctions, you must always a large number of lines can be cut at the separating strips. With well-known isolating plugs that consist of a coherent handle part and an integrally molded spike attachment for insertion into the respective

This makes operations time-consuming and can lead to switching ί errors.

The task of the innovation is to create a simply constructed and inexpensive isolating plug,
with which a variety of connecting lines, z. B.
ten lines can be separated at the same time.

This task is solved by a disconnect plug
from a flat plastic body, on the through ₍

In the following wild example of the innovation described in more detail with reference to the drawing. Show it:

Fig. 1 is a front view of the isolating connector

Fig. 2 is a side view of the isolating plug according to Fig.l.

The isolating plug shown in the drawing exists
from a continuous upper part 1, on which ten kamma-rtige prongs 2 are integrally formed. The spaces 3a, 5b between the prongs are adapted to the

The openings provided in the separating strip are narrower and wider. to pull the isolating plug out of the bar. Diesel eyelets 6a, 6b are also used to hang up a disconnect plug that is not required. To prevent the plug from being plugged in incorrectly, the narrower gaps 3 & between the prongs 2 can be listed less deep than the wider ones, or one or more of the prongs can have attachment tabs 8 in their upper part, both possibilities in Pig.
