1, an empty space (hole) is formed on the other surface of the electronic mounting part 200 to be assembled with the circuit part 100, and an inspection terminal of the circuit part 100 is opened and positioned outside The inspection terminal portion 300 is located.

2 and 3 are circuit diagrams of an inspection terminal portion of an ammunition electronic part functional inspecting apparatus for area defense according to an embodiment of the present invention.

The inspection terminal unit 300 is electrically connected to +, - (GND) of the power supply source 110 through a lead, and the leads connecting to the power supply source and the inspection terminal unit are electrically connected through another lead line .

At this time, the electronic mounting part 200 is filled with the molding liquid, which makes it impossible to inspect the function of the circuit part 100 because it is filled with molding liquid in the related art. Accordingly, the test terminal 300 can be placed on the backside of the PCB of the circuit unit 100 to supply a separate power source to inspect the function.

The power supply source 110 of the ammunition electronic ammunition function test apparatus for the area defense is a safety factor and + or - (GND) is short-circuited through the bridge conductor. Therefore, the inspection terminal is configured An external power supply unit 120 for opening between the positive terminal of the power supply source 110 and the electronic installation unit (power supply unit) is formed in the inspection terminal unit 300 as shown in FIG.

As shown in FIG. 2, in the short state, separate power supply is not possible. However, even if + and - (GND) of the power source are shorted in the open state as shown in FIG. 3, Power can be supplied through the power supply unit 120 separately. That is, it is possible to set whether or not external power supply is possible depending on whether there is a short between the two terminals.

Now, a method of performing a function test by supplying a separate power source through the external power supply unit 120 will be described in detail. First, the power supply supplies a separate power supply voltage having a voltage value similar to that of the power supply source 110 to the external power supply unit 120. At this time, the required power supply voltage is stably supplied to the circuit unit 100, and the local defense ammunition electronic unit function can be realized.

On the other hand, in the inspection terminal unit 300, inspection terminals capable of respectively identifying the functions implemented by the ammunition electronic part for area defense are positioned according to functions. Here, the functions implemented by the local defense ammunition electronic unit include the processing of a chemical article, the detection of a pirate line, and the self-destruction.

Here, when the power is supplied to the circuit unit 100, the local defense ammunition electronic unit implements a predetermined function at predetermined time intervals based on the power supply timing. Here, the preset function includes that the first chemical article is ignited after a predetermined time after the power is supplied, or the second chemical article is ignited after a predetermined time has elapsed after the power is supplied, or self-explosion occurs after a predetermined period of time after the power supply do.

At this time, one or more test terminals may be connected to a measuring instrument including an oscilloscope in order to check each output signal through each test terminal of the test terminal 300. The measuring instrument including the oscilloscope measures an output signal Check whether the function is normal or not. Further, the one or more test terminals may be provided with an external dimension of the ammunition housing for the local defense and a position and dimensions of one or more test terminals in the test terminal portion 300 for convenience of connection of one or more test terminals and an instrument including the oscilloscope The inspection jig including the jig pin can be connected.

[

After the molding process, the terminal plug 310 located in the inspection terminal 300 is removed, and the wiring can be removed using a jig pin or the like and connected to the measuring instrument. In this way, it is possible to supply the separate power supply through the external power supply unit 120 by using the inspection terminal unit 300 of the ammunition electronic amusement function test apparatus for the local defense, Can be confirmed through the inspection terminal unit (300).

In other words, by introducing a separate terminal stopper 310 to adjust the extent to which the molding liquid penetrates in the molding process, it is possible to secure safety to the power source 110 as well as the electronic installation part 200 of the ammunition electronic amusement function test apparatus for area defense It is possible to perform the function test through the inspection terminal unit 300 when the power supply source is short as a component or when the electronic installation unit 200 is covered with the molding liquid by the molding process.

In addition, since the inspection terminal portion 300 is sealed by the terminal stopper portion 310 so as not to be covered with the molding liquid during the molding process, the inspection jig suitable for the position of the inspection terminal portion 300 is applied, And the functions of the circuit unit 100 can be checked through the inspection terminals for each function.

As a result, the inventive ammunition electronic ammunition functional testing apparatus proposed by the present invention leads to innovative results that can be performed at any time before and after molding.
