Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a soft recovery test device for soft recovery of bullets fired from a gun, and particularly to a sensor for measuring internal ballistics and the like. The present invention relates to a storage terminal that stores specifications and the like or a connection terminal that connects these with a power source.

[Conventional technology]

The soft recovery of bullets fired from a gun is carried out in order to investigate the resistance of the shell of the bullet, the explosive charge inside the fuse, or the fuse to whether or not it can withstand the impact of the firing of the gun. According to the soft recovery method using the scoop, the behavior of the bullet when the bullet is fired from the gun, that is, even the trajectory inside the gun can be measured by an electronic device such as a sensor mounted inside the bullet. Here, the soft recovery method using scoop is
It converts the kinetic energy of a bullet into the momentum of water that is repelled by a bowl-shaped scoop attached to the tip of the bullet, gradually decelerating the bullet and recovering it with an impact less than 1/10 of the launch impact. is there. For example, length 60
A bullet that is driven into a V-shaped gutter that holds water at ~ 100 m is smoothly repelled by the scoop attached to the tip of the bullet, and gradually decelerates. On the top of the gutter, rails are framed upside down to prevent the bullet from jumping out of the gutter.

In such a scoop-using soft recovery method, the electronic device for measuring the trajectory inside the gun is mainly formed of a sensor for measuring the behavior of the bullet inside the gun and a memory for storing the measured data. Take out the machine together with the power supply,
The storage device is disconnected from the power source to enable reuse.
Therefore, the memory device is detachably joined to the sensor by the terminal, and the power source is also configured to have the joining terminal detachable from the sensor and the memory device.

However, in a normal case, the terminals (separable) that are joined between the output terminal of the sensor and the input terminal of the storage device and between the output terminal of the power supply and the input terminal of the sensor and storage device are separated temporarily. It is almost impossible to be in an open state, but when firing a bullet from a gun that impacts tens of thousands of G, considerable force is applied to each terminal, and the connection between terminals is instantaneous even There is a case where an open occurs, which becomes a noise source and erroneous signal data is stored in the memory. Also, due to the same reason, the power supply terminal may be temporarily opened and the storage device may not function.

[Problems to be solved by the invention]

The present invention has been made in view of such circumstances, and it is completely fixed so as not to be opened even by the impact of the firing of a gun, and after the test, the storage device etc. can be easily and damaged from the inside of the bullet. It is an object of the present invention to provide a soft recovery test device that can be taken out without any trouble.

[Means for solving problems]

The present invention includes: a. A device for a soft recovery test of a bullet fired from a gun, b. (I) a female terminal of a sensor for measuring ballistic specifications in the gun and a male terminal of a storage device for storing the sensor output. And (ii) the sensor and the female terminal of the power supply for supplying power to the storage device and the male terminal of the sensor and the storage device, c. The rear end of each female terminal is opened. The plug portion at the front of each male terminal is fitted into the sheath portion, and d. The adhesive attached to the head portion of the plug portion is inserted at the bottom of the sheath portion, e. Furthermore, the f. Soft recovery test apparatus has a notch that is separable from a female terminal joined by bending or the like of the male terminal in the vicinity of the center of each male terminal.

[Action]

The female terminal of the sensor and the male terminal of the storage device, and the female terminal and the male terminal of the power supply that supplies power to these are joined and fixed respectively, and after the test, the storage device and the power supply can be easily taken out from the inside of the bullet. A notch is provided in the male terminal so that the notch can be separated from the mating terminal by bending the notch.

〔Example〕

 The present invention will be described below based on embodiments with reference to the drawings.

In FIG. 1, a sensor 1 for measuring the internal trajectory of the gun and a storage device 2 for storing the output of the sensor are arranged with a spacer 3 for preventing close contact therebetween.

The sensor 1 and the memory 2 are different from the memory 2 with respect to the output terminal 6 which is a female terminal 5 soldered to the output line 4 of the sensor 1.
The input terminal 9 which is a male terminal to be soldered to the input line 7 is joined by fitting.

At the rear end of the output terminal 6, an open sheath 6a is formed,
On the other hand, the plug portion 9a of the input terminal 9 is fitted and joined, and the adhesive 10 attached to the vicinity of the head of the plug portion 9a is inserted into the bottom of the sheath 6a. In this case, it is desirable that the adhesive 10 adheres only to the vicinity of the head as much as possible and does not intervene on the side surface of the input terminal.

This is because it is not preferable that the joined input / output terminals become insulated by the adhesive and the conduction relationship becomes uncertain.

Further, the plug portion 9a of the input terminal has an appropriate length and is forcedly fitted by applying an appropriate external force, and at the same time, the outer wall of the plug portion is in direct contact with at least a part of the inner wall of the sheath portion. It is necessary to.

Note that the adhesive 10 can be made into a conductive adhesive by mixing a metal conductor such as gold powder or silver powder in order to further ensure the conductive state.

After the bullet is collected, the storage device 2 is taken out from the bullet. In the present invention, a notch 11 that can be easily separated from the mating terminal, that is, the output terminal 6 by bending the input terminal 9 to be joined is provided in the vicinity of the central portion of the input terminal 9 to be joined, and the sensor 1 is applied by an appropriate external force. The joining of both terminals can be released without breaking. Further, in the storage device 2 taken out by cutting, the input terminal 9 is detached from the portion of the soldering 8,
It can be used again as a new input terminal.

Although the above has mainly described the connection terminal of the sensor and the storage device, the same thing can be performed even if the power supply, the sensor, and the storage device connected by both male and female terminals are connected to each other.

[Effect of device]

The present invention is based on the above-mentioned structure, and even during the action of a strong G when the gun is fired, the terminals of the electronic device in the bullet do not become open, and the storage device Will store the correct data. In addition, it is said that the storage device can be easily taken out at the time of soft recovery, and can be reused sufficiently by making appropriate repairs to each terminal joint part etc., and it is said that conventional soldering is impossible. It is possible to achieve the same effect as or higher than that of soldering in the joint of the existing parts, and it is a very useful idea in practice.
