Description

[Detailed description of the invention] This invention relates to a case used to house a TV signal booster circuit, branch circuit, distribution circuit, etc., and more specifically to a case used outdoors.The purpose of this invention is to An object of the present invention is to provide a case that can maintain good waterproof properties.

The drawings showing the embodiments of the present application will be described below.

1 is the case body, which as is well known includes a top plate 2, a bottom plate 3, and a side plate 4.
It has a concave shape with a front side 6 opened by a back plate 5, and has accommodation spaces 7 for various electronic circuits inside.

Reference numeral 8 denotes a cylindrical body for drawing out electric wires, which is shaped so as to surround a through hole formed in the bottom plate 3.

Reference numeral 9 denotes a well-known fixture for attaching this case to a mast erected outdoors.

Reference numeral 10 denotes a protruding part extending around the periphery of the opening on the front side, including a protruding part 11 shaped like a podium, and a protruding part protruding from the front edge of the protruding part 11 in a flange shape. It is removed from the overhang piece 12.

Next, reference numeral 15 denotes a lid, which is shaped like a plate and is large enough to cover the opening of the case body 1.

Reference numeral 16 denotes an enclosing piece provided around the periphery of the lid 15, and a bringing-out piece 1 extending from the periphery of the lid 15 in the depth direction of the case body 1.
7 and a waterproof piece 18 extending from the tip of the holding piece 17 toward the top plate 2 and side plate 4 of the case body 1,
It is shaped to be large enough to surround the overhang 10.

Further, the tip end 18a of the waterproof piece 18 is
Both the inner surface 18a' and the inner surface 18a' are in contact with the outer surface of the case body 1 (the surface 18a' is the outer surface of the non-projecting part, and the surface 18a' is the rear surface of the bulging part 11).

Reference numeral 19 denotes a space surrounded by the bulging portion 11, the overhanging piece 12, the protruding piece 17, and the waterproof piece 18, which has an annular shape as shown in FIG. 5, and its lower end 19 a is open to the atmosphere.

If it rains while using the above structure, the opening of the case body 1 is covered with the lid 15, and the protruding part 10 is further surrounded by the enclosing piece 16, so that rainwater will not leak out. It does not enter the accommodation space 7.

In addition, in the above case, water droplets adhering to the part indicated by the symbol A or B may be found in the minute gap between the outer surface of the case body 1 and the tip surface 18a' of the waterproof piece tip 18a, or in the bulge 11. The space 1 is transmitted through the minute gap between the rear surface and the inner surface 18a'' of the tip 18a by capillary action.
9, the cross-sectional area of space 19 is large enough to prevent capillary action.
Furthermore, since the space 19 has an annular shape as shown in FIG. 5 and its lower end 19a is open to the atmosphere, rainwater that has entered the space 19 flows as shown by arrows 21 or 22. It is discharged from the lower end 19a.

Therefore, water intrusion into the accommodation space 7 is prevented.

As described above, in this invention, the projecting part 12 around the case body 1 has a square shape in front, while the lid body 1
Since the surrounding piece 16 around the main body 1 is also shaped like a square with its lower side opened corresponding to the above-mentioned projecting part 12, when the front opening 6 of the main body 1 is covered with the lid 15, the main body The cover body 15 is inserted into the opening 6 using the protruding parts 12 on both the left and right sides of the opening 6 as guides.
It has the advantage that it can be covered by lowering it along the direction, and that the closed state can be maintained by the weight of the lid body 15.

First, this has the effect that it is not necessary to use a stopper to maintain the closed state of the lid, and the operation is simple.

Second, when opening the lid 15, it is possible to easily operate the lid 15 by simply lifting it.

Thirdly, since it is a simple lid that moves up and down along the front opening 6, even when it rains lightly, the lid 15 can be lifted by half to 70 to 80%, and the river-like overhang can be lifted. Part 1
The electronic circuit inside the case body is inspected and adjusted through the front opening 6, with the lid 15 in the 0 and half-lifted states acting as an eaves to prevent rainwater from dripping onto the internal electronic circuit. There are also beneficial effects to be gained.

Furthermore, if it rains while the lid 15 is closed, even if the lid 15 is simply lowered as described above, the periphery of the lid 15 and the protrusion piece 17 will be damaged. The waterproof piece 18 surrounds the overhanging piece 12 on three sides, and the inner surface 18a'' of the waterproofing piece 18 overlaps the rear surface of the bulging part 11, so that rainwater is prevented from entering the overhanging piece 12. This can be prevented with a high degree of certainty, and as a matter of course, it is possible to prevent rainwater from entering the inside of the case body 1 beyond the overhanging piece 12, thereby being effective in preventing damage to electronic circuits caused by rainwater.

Moreover, in the above case, even if rainwater is pushed by strong wind and rain and is forced through the overlapping portion of the inner surface 18a'' of the waterproof piece 18 and the rear surface of the bulging portion 11, the place where the rainwater has been pushed is It is an annular space 19, and since the space 19 is shaped into a single shape and its lower end 19a is opened to the atmosphere, the pressure of the rainwater pushed in is eliminated, and the overhang piece 12 In addition, the rainwater that has lost its pressure is allowed to flow sideways and downward through the annular space 19 as shown by arrows 21 and 22 in Fig. 5, and is discharged from the opening at the lower end 19a. This has the effect of maintaining the waterproof state inside the case.

Furthermore, in the above case, even if rainwater reaches the tip of the overhang piece 12, the pressure of the rainwater has already been removed as described above, and furthermore, the front surface of the overhang piece 12 is exposed to the peripheral edge of the lid body 15. Since the rear surface of the portion overlaps, there is an effect that the overlapping portion can prevent the rainwater from entering the inside of the case body 1.

Furthermore, even if rainwater were to pass through the overlapped portion, since the lid 15 is in the form of an upright wall, the rainwater would travel down the rear surface of the lid 15 and fall, causing the enclosing piece 1
6 is not provided (as mentioned above, there is no enclosing piece provided to enable the lid to be opened and closed up and down), and the electronic circuit can be dropped from the lower edge and is provided inside the case body 1. This has the effect of preventing the rainwater from falling on the area.

As described above, the present invention has a structure in which the front opening of the main body 1 is covered with the lid 15 that moves up and down along the opening, making it easy to open and close, and it is possible to inspect and adjust the internal electronic circuit even in light rain. Moreover, it has a great practical effect of completely protecting the internal electronic circuit from rainwater without the need for packing or the like.
