By the way, if the repulsive force of the entire packing is increased in order to improve the dustproof performance and the waterproof performance, the repulsive force will be increased even in a portion where a sufficient repulsive force has been conventionally provided. As a result, a large force is required to crush the packing when closing the door, which makes it difficult to open and close the door. Further, when the electric device storage box is made of a thin steel plate, the housing or the like may be distorted. If the repulsive force of the entire packing is weakened with an emphasis on the workability of opening and closing work, dust and water may enter the box body from the portion where the fastening force of the door is weak.

The inventor of this case tried to solve this problem by diligently examining this point. An object of the present invention is to improve dustproof performance and waterproof performance by making the repulsive force of the packing different from the packing that receives a pressing force when closing the covering member of the electric device storage box.

In order to solve the above problems, the following means will be adopted. The first means is an electrical equipment storage box including a box body having an opening, a covering member covering the opening, and a packing located on the peripheral edge of the opening between the box body and the covering member. An electric device in which a drainage side is provided on the peripheral edge of the opening, packings having different repulsive forces are formed in two rows in the width direction, and the drainage side abuts on the packings arranged in parallel. It is a storage box.

In the first means, at the contact point between the drain side and the packing, the ratio of the contact area between the packing provided on the inner side and the packing provided on the outer side is changed so that the drain side comes into contact with the water cut side. Is preferable.

In the second means, it is preferable that the drainage side is mainly in contact with the packing provided on the inner side at the contact point between the drainage side and the packing arranged in parallel.

In the second means, it is preferable that the drainage side is mainly in contact with the packing provided on the outer side at the contact point between the drainage side and the packing arranged in parallel.

In the present invention, it is possible to improve the dustproof performance and the waterproof performance by making the repulsive force of the packing different from the packing that receives the pressing force when closing the covering member of the electric device storage box.

The embodiment for carrying out the invention is shown below. As can be understood from FIGS. 1 to 2, the electric device storage box 1 of the present embodiment includes a box main body 2 having an opening 21, a covering member 3 covering the opening 21, and a box main body 2. It is provided with a packing 4 that can be located on the periphery of the opening 21 between the covering member 3 and the cover member 3. Further, the packing 4 has at least a part of the repulsive force different from the repulsive force of the other part. Therefore, it is possible to solve the problem based on the uniformity of the repulsive force of the packing 4. Further, by setting each portion of the packing 4 to an appropriate repulsive force, the workability of opening and closing the door formed as the covering member 3 is improved. It should be noted that the force exerted by at least a part of the packing 4 on the covering member 3 is different from the force exerted by another part of the packing 4 on the covering member 3.

Here, an example of a specific means for changing the repulsive force of the packing 4 will be described. For example, the repulsive force of the packing 4 can be changed by changing the material of the packing 4, such as using a hard material and a soft material properly. Further, the repulsive force of the packing 4 can be changed by changing the material of the packing 4, such as using the rubber packing 4 and the sponge packing 4 properly.

The repulsive force can be changed depending on the form of the packing 4 and not depending on the material or the material. For example, the repulsive force changes depending on whether the packing 4 has a hollow shape or a solid shape (solid shape). Further, the repulsive force can be changed by changing the size of the packing 4. For example, the repulsive force changes between a thick one and a thin one.

As a means for making the repulsive force of the packing 4 different from other parts, a member may be attached and stacked on a member functioning as the packing 4. However, in this case, it is necessary to stack and paste the members. Similarly, it is also possible to change the repulsive force of a predetermined portion by applying a liquid substance or the like to a part of the member and hardening it. On the other hand, if the packing 4 is integrally formed, such work becomes unnecessary, and the efficiency of the work is improved. In addition, individual differences in dustproof performance and / or waterproof performance that may occur due to misalignment of the pasted portion are suppressed, so that it becomes easier to ensure quality.

When the packing 4 is provided by combining the parts having different repulsive forces, it is conceivable to stack the parts having different repulsive forces. In this case, the repulsive force can be adjusted by changing the ratio of the parts to be laminated.

As shown in FIG. 3, a portion where it is preferable to change the repulsive force of the packing 4 from another portion includes the periphery of the tightening portion such as the hinge 13 and the handle 12. Although the packing 4 of the present embodiment is integrally formed in a rectangular shape having four sides, the repulsive force is formed so as to be different between the portion colored in black and the portion shaded in FIG. 3 in FIG. There is. As shown in FIG. 3, if the repulsive force of the packing 4 corresponding to the periphery of the tightening portion for tightening the box main body 2 and the covering member 3 is different from the repulsive force of the packing 4 of other portions, tightening is performed. The configuration can be made in consideration of the influence of the applying force, and a more suitable electric device storage box 1 can be obtained.

Further, when the packing 4 is formed in a substantially frame shape, it is preferable to change the repulsive force with respect to the side adjacent to the tightening portion such as the hinge 13 or the handle 12, as shown in FIG. Although the packing 4 is integrally formed in a rectangular shape having four sides, it is formed so that the repulsive force is different between the portion colored in black and the portion shaded in FIG. 4 in FIG. As described above, if the packing 4 having a plurality of sides has a repulsive force of at least one side different from the repulsive force of the other side, it is possible to select a repulsive force suitable for each side. Therefore, it becomes possible to obtain a more suitable electric device storage box 1.

Further, as shown in FIG. 5, it is preferable to change the repulsive force of the corner portion of the frame-shaped packing 4 from that of other portions. Although the packing 4 is integrally formed in a rectangular shape having four sides, it is formed so that the repulsive force differs between the portion colored in black and the portion shaded in FIG. 5 in FIG.

Although not shown, when the packing 4 is formed in a substantially frame shape, the repulsive force of the packing 4 on the side located on the upper side at the time of installation may be changed to the repulsive force of the packing 4 on the other side. Since water or the like usually easily invades from the upper side of the electric device storage box 1, it may be possible to sufficiently secure the functionality by improving the waterproofness of the portion.

In the examples shown in FIGS. 3 to 5, a series of integrally formed packings 4 are attached to the back surface of the door, but separate members are arranged so as to be in contact with each other to form a sealing structure. You may. Further, as long as dustproofness and / or waterproofness can be ensured, as shown in FIG. 6, it is possible to have a structure in which a gap is provided between the separate members. Also in FIG. 6, the repulsive force is formed so as to be different between the black colored portion and the shaded portion.

By the way, in the examples shown in FIGS. 3 to 6, the structure is divided into two types, a portion where the repulsive force of the packing 4 is weak and a portion where the repulsive force is strong. In the examples shown in FIGS. 3, 4 and 6, the repulsive force is relatively weak at the positions where the tightening portions such as the handle 12 and the hinge 13 are adjacent to each other, or at the sides where the tightening portions are adjacent to each other. In other parts, the repulsive force of the packing 4 is relatively strong. In the example shown in FIG. 5, the corner portion of the frame-shaped packing 4 is configured to have a relatively weak repulsive force, and the other portions are configured to have a relatively strong repulsive force. ing. As a result, the opening 21 can be closed even if the tightening force at the corner is slightly weak. In the example shown in FIG. 5, the repulsive force of the packing 4 at the corner may be stronger than the repulsive force of the packing 4 at other portions, with an emphasis on water stopping.

In this way, it is possible to improve the problem by dividing the strength of the packing 4 into two types, but it is also possible to divide the strength of the packing 4 into three or more types. In the examples shown in FIGS. 7 and 8, the repulsive force of the packing 4 is divided into three types. In the examples shown in FIGS. 7 and 8, the packing 4 is integrally formed in a rectangular shape having four sides, but a black-colored portion, a shaded portion, and a gray-colored portion. And, the repulsive force is formed so as to be different.

In the example shown in FIG. 7, the repulsive force of the packing 4 is configured to be weak at the location where the hinge 13 is adjacent, and the repulsive force of the packing 4 is configured to be stronger at the location where the handle 12 is adjacent. Further, the repulsive force of the packing 4 at other parts is further strengthened. This is a configuration corresponding to the tightening force. The tightening force works most around the hinge 13, and becomes weaker in the order of around the handle 12 and other parts. By increasing the repulsive force of the packing 4 in places where the tightening force is difficult to work, and conversely suppressing the repulsive force of the packing 4 in the places where the tightening force is easy to work, the door opening / closing operation and dustproof and / or waterproofness can be achieved. We are improving both.

Similarly, in the example shown in FIG. 8, the repulsive force of the packing 4 is configured to be weak on the side where the hinge 13 is adjacent, and the repulsive force of the packing 4 is configured to be stronger on the side where the handle 12 is adjacent. .. Further, the repulsive force of the packing 4 on the other side is further configured to be stronger.

In the examples shown in FIGS. 3 to 8, the repulsive force of the packing 4 is substantially the same in the width direction, and is configured to have a portion different from other parts in the longitudinal direction. On the other hand, in the example shown in FIG. 9, it is configured in substantially the same manner in the longitudinal direction, and is configured so that there are portions having different repulsive forces in the width direction.

In the example shown in FIG. 9, the portions where the repulsive forces of the packings 4 are different are formed so as to form two rows in the width direction. The packing 4 is provided at a position where it can come into contact with the drain side 15, but the force exerted by the packing 4 differs depending on the state in which the drain side 15 and the packing 4 are in contact with each other. This point will be described with reference to the examples shown in FIGS. 9 to 12. In addition, in FIGS. 9 to 14, the portion colored in black is configured to have a weaker repulsive force than the portion not colored.

As shown in FIG. 10, when the drain side 15 provided in the box body 2 comes into contact with a portion mainly provided on the inner side having a relatively weak repulsive force, the force exerted on the covering member 3 becomes relatively weak. On the other hand, as shown in FIG. 11, when the portion provided on the inner side and the portion provided on the outer side are equally in contact with each other, the force exerted on the covering member 3 becomes slightly stronger. Further, as shown in FIG. 12, when in contact with a portion mainly provided on the outer side having a relatively strong repulsive force, the force exerted on the covering member 3 becomes stronger than in the example shown in FIG. That is, the force exerted on the covering member 3 can be adjusted by changing the ratio of the contact area between the portion having a weak repulsive force and the portion having a strong repulsive force at the contact portion between the drain side 15 and the packing 4. Further, the adjustment of the ratio of the contact area can be performed by changing the sticking position of the packing 4. If the drainage side 15 provided on the peripheral edge of the opening 21 is in contact with the packing 4 in which the portions having different repulsive forces are arranged in parallel, the force exerted on the covering member 3 can be relatively easily applied. Adjustment is possible.

In the examples shown in FIGS. 10 to 12, the packing 4 has a semicircular shape in a cross-sectional view, but any shape may be used as long as the gap between the box body 2 and the door when the door is closed can be filled, for example. As shown in FIG. 13, the cross-sectional view may be rectangular. Further, as shown in FIG. 14, it is also possible to provide a portion having a relatively strong repulsive force on the inner side and a portion having a relatively weak repulsive force on the outer side. Further, in the examples shown in FIGS. 9 to 14, the defect may be improved by dividing the strength of the packing 4 into two types, but the strength of the packing 4 may be divided into three or more types. Is also possible.

Although the embodiments have been described above with reference to some examples, the present invention is not limited to the above embodiments and can be various modes. For example, the strength of the packing can be different from that of the example of the embodiment, for example, the strength relationship can be the opposite of the strength relationship specifically described in the embodiment.

Further, the structure is not provided with a rotatable door, and it can be applied to a lid or the like to be screwed or the like. In this case, the portion to be screwed is the fastening portion. For example, when screwing the four corners, it is possible to make the repulsive force of the packing corresponding to the four corners different from other places.

The electrical equipment storage box may have not only one door but also a plurality of doors. In this case, the packing may be arranged so as to fill the gap between the two or more doors and the box body.

The packing may not be attached to the covering member but may be attached to the box body. At this time, it can also be attached to the drainage portion.
