When the shell 1 is fired and the electrolyte bottle (not shown) is ruptured in the power supply unit 4 and the electrolyte reacts with the leaked electrolyte, a rated voltage is immediately formed, and the electronic circuit unit built in the fuse 2 ( 3) may perform a predetermined function.

On the other hand, instead of some functions of the fuse (2) to determine the movement characteristics of the shell (1) to be fired is replaced by a telemetry (not shown) device is also tested. The telemetry functions to share the antenna part, the electronic circuit part, and the power supply part of the shell 1, and to process and transmit an input signal.

The signal transmitted from the telemetry is not only the actual rotation speed of the shell, but also the output status of the power supply, the operation status of the mechanical stabilizer, the operation status of the electronic circuit part, the current altitude, and the like. The operation state of (1) can be recognized.

The telemetry is configured in the shell 1 to test the operation state of the electronic circuit part 3 of the fuse 2, and even if the abnormality is corrected, the defective parts are used in the production process of the actual shell 1, such as poor assembly. Due to the factors, the desired function may not be maintained properly. Therefore, it is necessary to provide a predetermined inspection process for the final test to improve the reliability of the fuse 2 that influences the performance of the shell 1.

At this time, conventionally, as well as the measuring equipment for inspecting each function, there are many workers put into the inspection process to operate such measuring equipment, so the number of work is increased, which is a factor that lowers productivity.

Therefore, the present invention is a shell fuse electronic part for mounting the shell fuse and the function of the electronic circuit unit that generates the detonation signal when the target is detected by operating the power supply of the self-powered part after firing the shell with a minimum number of personnel in the production process of the shell. The aim is to provide a test apparatus.
