Description

[Detailed Description of the Invention] The present invention provides a hard maintenance case with a built-in device and two innings that match the external shape of the iron source inside the maintenance case so that the device i is installed in one track maintenance case to avoid vibrations. Regarding how to embed.

When electronic, mechanical, or other sensing devices are used in vehicles or other devices that generate vibrations,
Special arrangements must be made to prevent endangering the sensing equipment. Severe demands are placed on the functional reliability of the equipment, especially when performing extra-atmospheric spaceflight. Force and vibration loads are sometimes generated during launch and flight.In connection with the spaceflight industry, track maintenance cases are made to match the dimensions of each vibration sensing device, and sponge fm. It had a lining. ζ〇〇9 It is necessary to measure the equipment under test correctly and to adjust the lining mass in order to perform this side leg correctly. However, the tolerance for maintaining the recovery of the position of the device after vibration or shock is considerably large due to the tolerance for recovery of the sponge used as a buffer. Furthermore, the lining of the track maintenance case is complicated to manufacture and expensive.

The main object of the present invention is to provide the first-mentioned rigid storage case and its embedding method, which allows the device to be embedded in a hard storage case with considerable ease and improves conformity to the external shape of the device. It is on offer.

According to the present invention, this purpose is to place a re-foamed plastic material into a protective case, which is to be foamed with the device in the protective case, and to apply a coating to the device to repel the plastic material before foaming the plastic material. This is achieved by creating two innings.

This embedded method allows the am to be protected when the device is in operation. This means that the device is not only placed on the arm of the protective case, but also performs its functions within the protective case.

Appropriate power and control leads are routed through the wire retaining case and foam to the round to accomplish this. When the device is of a type that receives signals from the surrounding space 1
．． For example, in the case of an optical device, a suitable hole or a wall through which radiant energy can pass is provided in the wire and wire maintenance case.

In the case of optical devices, a tube is provided that passes through the foam;
This ensures that light from the shell 5s reaches the equipment through the fence and lining of the track case.The present invention provides a case that can be used commercially as a track case. In many applications, standard equipment and equipment can be used in sub-atmospheric spaceflight, as standard equipment and equipment can be used within the storage case. Therefore, there is no longer a device that uses a device with a special structure that meets the conditions required for extraatmospheric spaceflight. Even if the foam material itself does not change to dimension 1, it all intermingles at the Og location without forming a t-th continuity.

In addition, it is possible to make two innings of foamed material, making the processing work easier without requiring processing work such as cutting the two innings into precise dimensions.In addition, the equipment housed in this protective case A coating is applied before the foaming process to prevent the foam from sticking to the equipment, so even after the foaming process the equipment built into the case remains easily accessible.
The plastic film or plastic film is composed of a layer of fluoroethylene formed by the SUGLE process. A cut-out part of the device is used to allow the device to be pulled out of the lining. Care must be taken to ensure that the foam does not bulge out. For this purpose, the cut-out areas of the outer contour of the device are sealed or bridged with a filling material, such as a paste.

It is a device feature that the empty parts of the protective case, i.e. the spaces not occupied by the device, must be completely filled with foam material. In a variant of the invention, only the space within the protective case is filled with foam. A spacer holding the entire device pressed against the foam part in the retaining case is supported by at least one heel of the stock case. The wall of the maintenance case on which the spacer is supported is preferably recessed with a removable cover, so that the device can be easily withdrawn from the maintenance case after removal of the spacer.

The spaces not occupied by the device inside the protective case can be completely filled with foam. It is done. *1ml, # followed by # on the surface of the foam and unoccupied walls of the protective case.
A coating is applied to keep the foam tubes away from each other, creating blocks of foam that are separated from each other, and one of these blocks can be pulled out of the storage case and the device removed from it. It will be done like this.

The blocks of foam are advantageously separated at the level with the largest external dimensions of the nine scissors located within the protective case.

According to the invention, the lining is made of at least one foamed material.
@e) From f-lock 9, these two innings are separated from the device by a thin coating. This thin coating simply prevents the foam from sticking directly to the device and ensures that the device is always removed from the foam block. Make it removable.

1141e) In the case of a storage case made by the method of the variant, the device wire bundle is pressed against the removable cover by means of 41 spacers, and the corresponding parts of the 9 devices are separated from the spacers. Pressed against a block of foam.

In the case of a protective case made according to the method of the second variant and having nine linings, the device is surrounded by at least two blocks of foam, at least one of which has a lining of one Make it possible to take out the seven-iron rack. A particular advantage of this configuration is that the device is surrounded on virtually all sides by a foam lining. In the uninvented embodiment, the device is attached to the walls of the protective case by means of a rigid casing. 9 is given. With such a housing device, the device remains in a special position within the protective case during the foaming process, and the device remains in a special position during use.

In addition to the nine advantages mentioned above, the method of the present invention also provides
l The case and lining are extremely sugary, 91, l
l! The dimensions need only be slightly larger than the dimensions of the 4-case dimension line device.

Examples of devices that can be assembled without vibration by the method of the invention are electronic devices, mounting plates or mining equipment!
It is possible to open wrinkled parts such as transistors, optical devices such as a-air tape devices and interferometers, etc. ・Unexploded 94 can be applied to vehicles flying in space outside the atmosphere gate, as well as land vehicles. Nose/underwater ride, shock during vibration a
