接続する。In order to protect the electronic unit 2 housed in the camera case from rain, wind, dust, and gas, it is necessary to seal the inside of the camera case. For this reason, a glass 4 is attached to the front surface of the camera case 1 housing the electronic unit 2 via a front rubber gasket 3 with a cover 5. On the other hand, the plug 7 is passed through the plug passage hole 12 and connected to the electronic unit 2.

、防水効果を得ている。At this time, in consideration of maintenance, the penetration fitting 8 inserted in advance into the cable 6 is inserted into the penetration fitting rubber gasket 11.
It is screwed into the threaded portion 13 of the plug passage hole 12 through the screw. Next, attach the penetrating fitting presser 1 via the cable rubber gasket 9.
0 into the through fitting 8. By increasing the screwing amount, the cable rubber packing 9 is compressed and presses against the circumferential surface of the cable 6. Thus, the front rubber gasket 3
゜Cable rubber gasket 91 Penetration fitting rubber gasket 11
As a result, the inside of the camera case 1 is airtightly separated from the outside, and a waterproof effect is obtained.

た。Since the conventional camera case waterproofing mechanism is configured as described above, when the camera case 1 suddenly cools down from a high temperature state due to rain, etc., the internal pressure of the camera case 1 decreases and the rainwater from the outside is absorbed by the breathing effect. In addition, moisture and rainwater may enter from scratches at the end of the cable or in the middle of the cable, and there is no tightening regulating part near the rubber gasket 11 of the penetrating fitting, so how far should the penetrating fitting presser 10 be tightened? Not only is it impossible to avoid deterioration of the penetration fitting rubber gasket 11 due to over-tightening of the penetration metal fitting presser 10, but also deterioration due to compressive hardening of the cable 6 at the cable rubber gasket 9, and the cable 6 is
Since it is necessary to attach a through-metal fitting 8 to the wiring, there is a problem that this metal part comes into contact with other members and becomes a hindrance during wiring processing.

An aluminum plate 20 is fixed with screws 21 via the electronic unit I.18. Next, the board 19 to which the electronic unit 18 is attached is fitted into the rear notch of the camera case 14, and the liquid seal 25 is applied around the plug 26 attached to the back of the board 9. Furthermore, attach the cover 22 to the back of the camera case 14 via the cover rubber gasket 23 by screwing the screw into the screw hole 33. At this time,
The substrate rubber gasket 24 is bonded to the liquid seal 25 attached to the substrate 19, and the warpage of the substrate 19 is restricted by the contact 32. Next, while fitting the cable rubber gasket 28 attached to the cable 27 into the contact boss 34 as shown in FIG.
Attach to. Then, place the cable cover 30 on the cable rubber gasket 28 and tighten it with the screw 31 until it hits the boss 34 as shown in FIG. 3.

For this reason, even if the camera case 14 suddenly cools down due to rain, etc., the circuit board 19 and cover go 11 gasket 2
3. The two airtight spaces separated by the substrate rubber gasket 24 can prevent the internal pressure from changing suddenly and can prevent rainwater from entering from the outside. Furthermore, even if moisture were to infiltrate into the cable cover 30 through a scratch on the end of the cable 27, the space within the cable cover 30 is small and is not easily affected by atmospheric pressure, so the infiltration of moisture is substantially sufficiently prevented. Even if it does, it will not enter the airtight space on the electronic unit 18 side.

９，２６の連結を容易。In addition, when attaching the cable cover 30 with the screws 31, excessive contraction of the cable rubber gasket 28 is sometimes restricted by the contact boss, which may cause deterioration of the cable rubber gasket 28 due to over-tightening of the screw 31 or deterioration due to compressive hardening of the cable. can be prevented. In addition, since there is no need to attach a penetrating fitting to the cable 27 as in the conventional case, the connector 27
Easy to connect 9 and 26.
迅速に行える。Can be done quickly.

A plug 29 may be attached to this, and silicone rubber 36 may be injected into the cable cover 30 to form an integrated structure. Such an integral structure allows for easy attachment to the cover 30, and the elasticity of the silicone rubber 36 more reliably blocks the infiltration of rain, moisture, and dust.
また、ケーブルカバー３０は第７図に示すように向きを
上記とは逆にして取り付けることができ、この場合には

できるものが得られる効果がある。As described in Part 2, according to the present invention, the front opening of the camera case is hermetically closed with glass via the front rubber gasket, the -F electromotive unit is attached, and the back side of the camera case is closed with a board. Then, an electronic unit is installed inside it, and a cover is attached to the back of the above board and camera case via rubber gaskets, except for the area around the board side connector, and a cable cover is attached to the back of this cover, and the cable side The end of the cable with the plug is held through the cable rubber gasket, and together with the above board, it is configured to form an airtight space independent of the airtight space on the -h electronic distribution unit side, so rain etc. can be kept away from the camera case. It can be blocked by the surrounding rubber gasket,
In addition, since the airtight space on the cable side is small, moisture from the ends of the cable and scratches on the cable is not easily affected by atmospheric pressure, and it is possible to sufficiently prevent moisture from entering this space. It is possible to reliably prevent any impact on the airtight space on the electronic unit side, and since a part of the board is used to form the airtight space, there is no need for more parts or higher costs than before. This has the effect of providing something that can prevent this.
