Embodiment Construction
[0019] The present invention can be explained in more detail by the following examples, and the present invention is not limited to the following examples;
[0020] The present invention is based on the attached Figure 1~3 The described strong electromagnetic pulse protection device for a track circuit receiver includes a mounting connector, a box body, a pre-stage suppression printed circuit board 9, a second-stage filter function printed circuit board 10, and a post-stage high-speed limiter. Width printed circuit board 11, the box body is a metal box body with wave-absorbing shielding function. The socket 1 for the receiver and the plug 8 for the track receiver, the socket 1 for the track receiver is connected to the external terminal, and the plug 8 for the track receiver is connected to the receiver end. During implementation, the specific structure of the socket 1 for the track receiver and the plug 8 for the track receiver The form is a socket and a plug that match the...
