Abstract

The electromagnetic seal uses flexible finger stock captivated in a simple channel. In this arrangement, the fingers of the seal are protected against damage and the slits between them are lapped by the channel to improve the shielding properties of the assembly. The seal is shown applied to a cabinet having frame member 10 and cover 12. The latter mounts seal assembly 14 for cooperation with striker 16 mounted by frame 10. Assembly 14 consists of channel 18 mounted by cover 12 and finger stock 20 captivated in channel 18 by its own spring tension. Stock 20 has a normally flat back portion 22 and wing portions 24 and 26. These are slit in the usual manner into cantilevered fingers so that stock 20 can conform to the shape of surfaces between which it is compressed.

Captivated Finger Stock Seal

The electromagnetic seal uses flexible finger stock captivated in a simple channel. In this arrangement, the fingers of the seal are protected against damage and the slits between them are lapped by the channel to improve the shielding properties of the assembly. The seal is shown applied to a cabinet having frame member 10 and cover 12. The latter mounts seal assembly 14 for cooperation with striker 16 mounted by frame 10. Assembly 14 consists of channel 18 mounted by cover 12 and finger stock 20 captivated in channel 18 by its own spring tension. Stock 20 has a normally flat back portion 22 and wing portions 24 and 26. These are slit in the usual manner into cantilevered fingers so that stock 20 can conform to the shape of surfaces between which it is compressed. As cover 12 closes to the position shown, assembly 14 engages striker 16 and stock 20 20 is compressed into channel 18. The resulting arching of portion 22 provides line contact with striker 16 along edges 28 and 30 providing a good seal between those parts. Similarly, channel 18 is dimensioned so that its inturned portions 32 and 34 not only lap portions 24 and 26 to a considerable extent, but also provide edges. These bear against the outer surfaces of the fingers, providing lines of contact within assembly 14 which are additional to those at the ends of the fingers.
