The present invention relates to an insulator for a rail tap-off.

In particular, the present invention is coated on the surface of each metal member of the state-of-the-art memory and the iron assembly assembly with a composition of a combination of natural rubber and EPDM (Ethylene-Propylene-Diene Tetrapolymer) in a certain proportion to the high-voltage railroad The present invention relates to an insulator for railroad turnouts that prevents short circuits to the tap-offs.

Railroad tap-offs are devices that diverge trams or trains from railroads and enter them in the desired direction.

Such a railroad tapping machine usually has a high voltage applied to a railroad or train when it enters a train or a train. In order to prevent this, an insulating member has been inserted and used to insulate each metal member of the tip-memory and iron assembly.

However, the conventional assemblies have caused the disadvantage described below by using the insulating member as described above, which will be described in detail with reference to FIGS. 1 to 4.

Referring to FIG. 1, the rail branching portion 40 has a rail branch 40 that is mechanically connected to the auxiliary rail 20 with each other end of the close contact 42 and 44 mechanically connected thereto 40. By being mechanically connected to the connected tip-memory assembly 150 and the auxillary assembly 160, the auxiliary rail 20 is pulled or pushed by the rail tap-off 40 so as to be in close contact with a specific driving rail 10. Branch the tracks.

The rail tap-changer 40 pushes or pulls the auxiliary rail 20 which is mechanically connected to the two ends 42 and 44 of which one end is mechanically connected at the same time by an electrical operation, to the specific driving track 10. Close contact Here, this drawing does not show that the traveling track 10 diverges.

More specifically, each of the close contact 42, 44 is a drive rail 10 as described above by interlocking the tip-memory assembly 50 and the iron assembly 60 mechanically connected to the auxiliary rail 20, respectively. Branch to.
