Device for absorption of noise

摘要

A device for absorption of electrical noise on lines contains a housing which is formed from two half-shells, which are connected to one another with the aid of a film hinge and, in the area of their opposite edges, have a locking device, which locks the two half-shells. A ferrite element is held in each half-shell. An aperture or a window is formed in the wall of one half-shell, through which the locking device can be seen, which locking device acts per se in a depression within the wall. Through this aperture it is possible to check and to inspect whether two elements which form the locking device are correctly seated.

主权项

1. A device for absorption of electrical noise, having
a housing, which comprises two housing half-shells (1, 2) for receiving in each case one element (7) made of a noise-preventing material, and in the closed state in both end face walls thereof in each case one passage opening (3, 3) for one or multiple cables, in each housing half-shell (1, 2) an element (7) made of the noise-preventing material which comprises in each case a semi-cylindrical groove (8) forming an essentially closed cylindrical passage for at least one cable in the assembled state of the housing, as well as having a locking device which is operative inside the wall of the half-shell (1) to transition from an unlocked position, both positions being, visible through an aperture (15) of the wall of at least one housing half-shell (1).
