Printed circuit protecting fuse - is formed integral part of printed circuit board in radio receiver

摘要

A security device for circuit sections of a receiver installation comprises a fuse (23). The receiver has a pair of polar terminals (19, 20) with an earth terminal (21). In a transmitted signal generator corresponding polarity terminals (13, 14) are provided together with earthed terminal (15). The safety fuse (23) is positioned in circuit downstream of the junction point (20) and of the receiver (22). The application of the fusable section as an integral part of a printed circuit board is also described.
