DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a distribution board, a distribution board,
The present invention relates to a device housing for housing and arranging electric devices such as a switch, a relay, and a fuse, and other devices, such as a control panel.

[0002]

2. Description of the Related Art Equipment for storing and arranging electrical components such as switches, relays, fuses and other equipment inside, such as distribution boards, distribution boards, and control boards installed in ships. The housing has conventionally been manufactured by combining angle members or plate members made of steel and welding and fixing the joints.

[0003] Specifically, a frame as a base of a housing is made by welding an angle material or the like which has been cut to a predetermined size and the shape of which has been adjusted, and a plate material is attached to this frame by welding or a bolt and a nut. A method of forming a housing or a method of forming a housing by welding plate materials reinforced with an angle material or the like to each other by welding are adopted. In addition, there is also a structure in which an angle material for reinforcement or the like is attached to a corner portion of a housing formed of a plate material.

[0004] Since such a device housing is required to be lightweight and high in strength, it is manufactured using a relatively thin plate. However, as means for increasing strength, side edges of the plate are used. It is assembled using a plate material in which a portion is bent in a U-shape, or a so-called hemmed plate material in which side edges of the plate material are folded 180 degrees and overlapped in a close contact state.

[0005]

A conventional housing for storing equipment is manufactured by combining angle members and plate materials made of steel and welding the joints, so that much labor and time are required until completion. Is required. In addition, when a relatively thin material is welded, deformation is apt to occur due to tension, strain, and the like, and it can only be manufactured by a skilled welding technician. That is, in order to ensure a certain level of quality and accuracy, a skilled welding technician with advanced technology and experience is indispensable.

In addition, since conventional housings for housing equipment are often made of a steel material, an increase in weight cannot be avoided in order to increase the strength by increasing the thickness of the material or increasing the amount of reinforcing material. . In particular, in the case of a control panel arranged in a ship such as a high-speed ship, the demand for weight reduction is extremely large.However, a conventional equipment housing made of steel material has reached a satisfactory level. It is not the situation.

In order to reduce the weight, it is conceivable to use an aluminum-based material or the like. However, the aluminum-based material cannot be welded unless a special welding method is used. Is difficult and there is a risk of damage due to cracks.
It cannot be easily adopted.

Further, since the aluminum-based material is remarkably work-hardened, when hemming or the like is performed, defects such as cracks are easily generated on the outer surface portion of the bent portion, which also hinders the use of the aluminum-based material. It is one of the factors.

That is, it is known that the use of an aluminum-based material can reduce the weight of the housing. However, it is difficult to perform welding, and cracks are likely to occur when bending such as hemming is performed. Actually, aluminum-based materials cannot be used for such reasons.

The problem to be solved by the present invention is to provide a lightweight, high-strength, excellent vibration-proof function, easy manufacture,
An object of the present invention is to provide a housing for device storage which can be manufactured in a short time.

[0011]

As a method of enhancing the rigidity of a plate material, a method of increasing the section modulus by performing bending processing in consideration of workability, workability, finishability, economy, and the like is currently used. This is the best way.

On the other hand, it is possible to further increase the rigidity by increasing the number of bent portions, but there are restrictions on the size and shape of the housing, and there is a possibility that a problem may occur in an actual machining operation. is there.

Therefore, rigidity is achieved by minimizing the number of bends, performing a bending process for easily attaching a reinforcing member such as a rib, an equipment mounting plate, and the like, and further forming a housing by combining the respective members. It is desirable that the strength of the entire housing becomes high.

Therefore, based on such viewpoints, as a result of repeated research and experiments from various directions, the present inventors have come to invent the housing for equipment storage according to the present application.

[0015] In order to solve the above-mentioned problems, a housing for equipment according to the present invention is characterized in that a plurality of plate members each having a bent reinforcing portion formed by bending a side edge into a U-shape are connected to each other by means of detachable joining means. It is characterized by being formed in a housing shape by joining. Here, the bending reinforcement portion refers to a portion formed by bending a side edge of a plate material by 180 degrees to form a U-shape having a space inside the plate material where the plate material does not contact each other.

According to this structure, the plate having the bent reinforcing portion is less likely to be deformed than the one subjected to the hemming process, and the strength is increased. Can be formed, whereby the weight can be reduced. Further, by using the bent reinforcing portion formed on the plate material or the extended portion thereof as a bonding portion, the plate materials can be bonded to each other by bonding means other than welding, so that the production becomes easy and the time is short. It can be manufactured at

The strength of the plate having the bent reinforcing portion is
The reason for the improvement over the conventional plate material that has been hemmed is
This is because the rigidity is increased by forming the space portion in the bending reinforcing portion, as in the case where the thickness of the plate material is increased.

Here, with reference to FIG. 9, a description will be given of the difference in strength between the U-shaped plate member and the conventional hemmed plate member constituting the device housing of the present invention. FIG.
(A) is an end view showing a U-shaped structural plate, and (B) is an end view showing a conventional hemmed structural plate.

As shown in FIG. 9, the U-shaped plate 71 and the hemmed plate 72 formed in the same manner as the plate thickness b1, the bent portion height h3, and the plane portion width b3 under the same conditions. When the section modulus was calculated on the basis of specific numerical values, the section modulus of the U-shaped plate 71 was larger than the section modulus of the hemmed plate 72 in both the X and Y directions. found. Therefore, the U-shaped plate 71
It can be seen that is higher in rigidity and higher in strength.

It has also been found that in the case of a U-shaped plate having bent reinforcing portions formed on both sides as well as on one side of the plate, the substantial rigidity is at least 1.8 times that of the hemmed structure plate 72. . Further, in the case of the U-shaped plate 71, the overall strength can be changed by changing the thickness b2 of the space portion, the width b3 of the plane portion, and the height h3 of the bent portion. It can be adjusted to any strength.

Furthermore, in the housing for housing equipment according to the present invention, it is desirable that the thickness of the bending reinforcing portion is 3 to 10 times the thickness of the plate material. Since there is a space inside the bent reinforcing portion formed on the side edge of the plate material, the thickness of the bent reinforcing portion is thicker than the thickness when the plate material is bent 180 degrees and overlapped in a close contact state. However, by setting the thickness of the bent reinforcing portion to be three to ten times the thickness of the plate, the highest strength can be obtained in the plate having that thickness.

Note that the thickness of the bent reinforcing portion is 3 times the thickness of the plate material.
When the thickness is smaller than twice, the strength increasing effect is reduced and cracks and the like are easily generated on the surface of the bending reinforcing portion. Conversely, when the thickness is larger than 10 times, the strength increasing effect is obtained,
Since the degree of the decrease and the tendency of inviting a decrease in the internal volume of the housing appear, the optimal range is 3 to 10 times. However, the overall strength depends on the size, shape, structure of the housing for equipment storage, the thickness of the plate material, and the presence or absence of reinforcing materials. It is desirable to decide after doing so.

On the other hand, in the housing for housing equipment of the present invention, screws can be used as means for detachably joining the plate members. By using screws as detachable joining means, it is possible to join plate materials with a general tool, and it is possible to simplify the joining work, so that even non-skilled workers can easily assemble It is possible to shorten the production time.

Further, in the housing for housing equipment according to the present invention, it is possible to adopt a structure in which a reinforcing member is arranged between the bending reinforcing portions formed to face the plate material. By arranging such a reinforcing member, a structure in which ribs are partially provided is provided, so that the rigidity of the plate member is increased, the strength of the housing is further improved, and the function of suppressing vibration is also exhibited. In this case, it is desirable to arrange an appropriate number of reinforcing members according to various conditions such as the size and shape of the housing, the required strength, and the degree of vibration.

Further, since the reinforcing member can be used as a mounting member when arranging shelves and members for arranging various devices inside the housing, the convenience is improved. In addition, as the reinforcing member, an angle material, a U-shaped material, a C-shaped material, or the like can be suitably used, and a screw or the like can be used as a joining means between the reinforcing member and the plate material.

On the other hand, in the housing for housing equipment according to the present invention, a plate made of an aluminum-based material can be adopted. With such a configuration, it is possible to significantly reduce the weight without losing the required level of strength. The aluminum-based material is remarkably work-hardened and tends to crack when subjected to bending. However, in the case of the present invention, since the bending reinforcing portion has a U-shaped structure having a space portion, cracking occurs. There is no risk of occurrence.

[0027]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a housing for device storage according to an embodiment, FIG. 2 is a longitudinal sectional view of the housing for device storage, FIG. 3 is a cross-sectional view of the housing for device storage, and FIG. It is a partially cutaway front view of the housing | casing for apparatus storage. FIG. 5 is a perspective view of a plate member constituting the device housing, and FIG.
FIG. 3 is a cross-sectional view of the plate material.

The device housing 10 of the present embodiment is used as a control panel installed in a ship. As shown in FIG. 5, in the device housing 10, four plate members 12 each having a bent reinforcing portion 11 formed by bending a side edge into a U-shape are attached to a back plate using bolts and nuts 13. 1
A housing is formed by joining around the periphery of the door 4, and a door 16, which can be opened and closed around a hinge 15, a lock mechanism 19, and the like are provided on the front surface thereof. Further, the bending reinforcing portion 11 of the plate member 12 has a space portion 17 inside thereof. The back plate 14 is a device mounting plate for mounting various instruments and control devices housed in the housing.

By forming the bending reinforcing portion 11 having the space portion 17 in the plate material 12, the rigidity is increased and the plate material 12 is less likely to be deformed than the conventional plate material subjected to the hemming process. Even so, it is possible to form a high-strength housing, whereby the weight of the housing can be reduced. The reason why the strength of the plate material 12 having the bending reinforcing portion 11 is higher than that of the plate material subjected to the hemming process is that the thickness of the plate material 12 is increased by forming the space portion 17 in the bending reinforcing portion 11. This is because the rigidity increases as in the case.

Further, the bent reinforcing portion 11 is joined to the periphery of the back plate 14 using bolts and nuts 13 by using the joining portion 18 formed by extending the plate material 12 in the vertical direction. Since it is possible to form a housing by joining them together, they can be assembled without a welding step, which facilitates production. That is, there is no need for a skilled welding technician or the like, and even a general worker can easily manufacture it.
It can be manufactured in a shorter time than before.

As shown in FIG. 7, the corners of the housing 10 for the equipment are brought into contact with each other by forming the joining portion 18 of the plate member 12 into a shape cut at 45 degrees. Since it is assembled so that the end face of the other plate member 12 is covered by the flat portion 20 formed in a protruding shape at the portion, there is no gap and the appearance is good.

Further, in the housing 10 for accommodating the device, the C
The reinforcing member 21 which is a profile is arranged. With such a structure, the plate member 12 and the reinforcing member 2
Since a box structure surrounded by 1 is formed, an action similar to that of the rib is generated, the rigidity of the plate member 12 is increased, and the strength of the housing is further improved. In addition, since the anti-vibration function is increased, various instruments and control devices housed in the housing can be prevented from malfunctioning or being damaged by vibration. Further, the reinforcing member 21 is convenient because it can be used as a mounting member when a shelf, a member for arranging various devices, and the like are arranged inside the housing 10 for device storage.

On the other hand, as shown in FIG. 8, the joint between the plate members 12 is formed by an angle member 30 and a bolt / nut 31.
And the frame base member 32 is attached to the bottom of the housing, so that it has high strength and excellent vibration prevention function.

Further, the housing 10 for accommodating the device of the present embodiment
In FIG. 6, as shown in FIG. 6, the thickness 11t of the bent reinforcing portion 11 is about five times the thickness 12t of the plate material 12, but no cracks or the like occur in the process of forming the bent reinforcing portion 11. The maximum strength at the plate thickness was obtained. Since the strength of the entire housing is affected by the size of the thickness 11t of the bending reinforcing portion 11, the thickness of the material, the size, shape and structure of the housing, the type of equipment to be housed in the housing or the housing It is necessary to determine the value after sufficiently considering various conditions such as the magnitude of vibration at the installation location.

On the other hand, in the housing 10 for housing equipment of the present embodiment, since the bolts and nuts 13 are employed as means for detachably joining the plate 12 and the like, as described above, a skilled welding engineer is required. This is unnecessary, and a general worker can easily perform the assembling work, and the production time can be greatly reduced. For example, regarding the time required for manufacturing the device housing 10 of the present embodiment,
As compared with the conventional welding method, the manufacturing time was reduced to about 1/5 to 1/7.

Further, since the plate member 12, the back plate 14, the door 16 and the like constituting the housing 10 for the device storage are made of a plate material made of an aluminum-based material, the required level of strength is not lost. The weight was reduced. The aluminum-based material is remarkably work-hardened, and tends to crack when subjected to bending. However, in the case of the device housing 10 of the present embodiment, the bending reinforcing portion 11 is Since there is no U-shaped structure, there is no risk of cracks or the like.

The equipment housing 10 of the present embodiment is used as a control panel installed in a ship. However, since the housing 10 is lightweight and high-strength and has an excellent vibration isolation function, it can be used for a high-speed ship or the like. Can also be suitably adopted. Note that the housing for housing equipment of the present invention is not limited to this use, and thus can be widely used in various industrial fields as a housing for housing and arranging various kinds of equipment.
