Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transformer mounting member, and more particularly to a transformer mounting member that can be bent appropriately according to the condition of the transformer mounting position at a transformer mounting site.

[0002]

2. Description of the Related Art Conventionally, as a transformer mounting member for mounting a transformer body used for a neon tube or the like on a wall surface, a metal rectangular plate-shaped member is preliminarily bent into a predetermined shape. in use.

FIG. 9 is a plan view showing a conventional transformer mounting member, and FIG. 10 is a side view showing the conventional transformer mounting member.

The conventional transformer mounting member 1 is usually a lightweight metal such as aluminum having a thickness of about 1 to 3 mm or SPC.
A rectangular plate-shaped body made of a steel plate such as C or SECC is used, and is excellent in strength so that the transformer body 2 having a certain weight can be securely mounted. For example, as shown in FIG. 9, the left and right ends of the transformer mounting member 1 are provided with screw-fastening holes 3 and screw-fastening notches 4, and as shown in FIG. Has been applied.

That is, a valley-curved portion which is bent in a valley shape by press working or the like at a position slightly inside from the screw-fastening hole 3 and the screw-fastening notch 4 formed in the vicinity of both ends of the transformer mounting member 1. 5 is provided, and at a position further inside the valley-curved portion 5, there is a mountain-curved portion 6 which is also bent in the shape of a mountain by pressing or the like. The shape, angle, etc. of these bending processes differ depending on the size and mounting location of the transformer main body 2, but by this bending process, a predetermined space is provided between the transformer main body 2 and the wall surface, etc., and the bending occurs in the transformer main body 2. Helps to dissipate heat.

The transformer mounting member 1 is mounted on the transformer body 2, and the central portion of the transformer mounting member 1 and the transformer body 2 are arranged.
The back surface of the housing is fixed by the spot welding portion 7.

Therefore, when actually mounting the transformer main body 2 on a wall surface or the like, first, the transformer mounting member 1 is bent in advance into a predetermined shape and fixed to the transformer main body 2.
Using the screw holes 3 and the screw cutouts 4 of FIG.
As shown in FIG. 5, the attachment is performed by screwing with a screw 8 as shown by the alternate long and short dash line.

[0008]

As described above, since the conventional transformer mounting member 1 is excellent in strength to some extent, it is necessary to bend it in advance by using a press working machine or the like. . However, in the actual mounting position,
The transformer mounting member 1 may not be used as it is due to the surrounding arrangement of devices. That is, depending on the condition of the transformer mounting position, the transformer mounting member 1
The dimension, bending angle, or bending direction of was sometimes incorrect. In such a case, it is necessary for an operator to manually rework the transformer mounting member 1 according to the situation of the transformer mounting position at the transformer mounting site. However,
In the conventional transformer mounting member 1, it is extremely difficult to manually correct it. Even if it can be manually corrected, the transformer mounting member 1 is distorted in its external appearance, thereby deteriorating the commercial value. .

In addition, the bending process itself requires equipment, and it is very troublesome in machine operation to perform various types of processing each time depending on the transformer mounting location, and mass production cannot be performed. Because of the high cost, it has been desired to develop a transformer mounting member that can be bent more easily at a lower cost depending on the situation of the transformer mounting position at the transformer mounting site.

Therefore, according to the present invention, the simple structure enables bending work to be performed very easily according to the situation of the transformer mounting position at the transformer mounting site, and the production process does not require the equipment and operation of the press machine. It is an object to provide a relatively inexpensive transformer mounting member that can be mass-produced.

[0011]

A transformer mounting member according to the invention of claim 1 is fixed to a transformer main body, and is provided in the vicinity of an end of a metal plate member for mounting the transformer main body at a predetermined position. A notch is provided in the vicinity of the end portion so that it can be bent depending on the situation of the transformer mounting position at the transformer mounting site. Here, the notches may be provided at both ends of the bent portion of the transformer mounting member, or may be provided in a groove shape along the bent target portion.

A transformer mounting member according to a second aspect of the present invention is fixed to a transformer main body, and is provided in the vicinity of an end of a metal plate member for mounting the transformer main body at a predetermined position.
Notches are provided at the respective bending target portions so that the vicinity of the end portion can be bent at the transformer installation site.

In the transformer mounting member according to the invention of claim 3, the size of the notch of claim 2 differs depending on the bending order.

In the transformer mounting member according to the invention of claim 4, the size of the notch of claim 3 is larger than the notch of the bending target part to be bent first and the notch of the bending target part to be bent later. It was done.

[0015]

According to the transformer mounting member of the invention of claim 1,
Since the notch is provided in the vicinity of the end of the metal plate for mounting the transformer body at a predetermined position, the cross-sectional area of the notch is smaller than that of other parts without notches, and bending stress is reduced. Since the size is small, even a transformer mounting member having a certain degree of strength can be bent by human power at a transformer mounting site.

According to the transformer mounting member of the second aspect of the present invention, a plurality of bending target portions are provided at respective bending target portions so that a plurality of metal plate-shaped members for mounting the transformer main body at a predetermined position can be bent at a plurality of positions. Since each is provided with a notch, the cross-sectional area of the notch is smaller than that of other parts without a notch, and the bending stress is reduced. Multiple bending can be done by human power.

According to the transformer mounting member of the third aspect of the present invention, since the size of the notch of the plate-like body differs depending on the folding order, the cross-sectional area of each notch also differs according to the folding order. ,
The magnitude of the bending stress also differs depending on the bending order, and bending can be performed manually by the bending order.

According to the transformer mounting member of the fourth aspect of the present invention, the size of the notch of the plate-shaped member is set such that the notch of the bending target portion is bent later than the notch of the bending target portion that is bent first. Since it is made larger, the cross-sectional area of the bending target part to be bent first is larger than the cross-sectional area of the bending target part to be bent later, and the bending stress of the bending target part to be bent first is also to be bent later. Since the bending stress of the notch part of the bending target part to be bent is larger, the bending target part to be bent later is easier to bend than the bending target part to be bent first, and the bending part to be bent first Is not affected by the later bending process.

[0019]

Embodiments of the present invention will be described below. FIG. 1 is a plan view showing a main part of a transformer mounting member according to a first embodiment of the present invention.

First, the structure of the transformer mounting member before bending will be described. Transformer mounting member 10 of the present embodiment
Uses a light-weight metal such as aluminum with a thickness of 1 to 3 mm or a rectangular metal plate made of steel such as SPCC or SECC so that it can be mounted securely even with a heavy transformer. Has been done. And
As shown in FIG. 1, screw holes 11 are formed at the left and right ends of the rectangular metal plate, which are slightly inward from the left and right ends. A first notch 12 and a second notch 13 are provided at predetermined positions at opposite positions on the upper side and the lower side of the hole 11 which are further inside. The first cutouts 12 and the first cutouts 12 at the facing positions are paired up and down, and the cutouts at the facing positions are formed at the same distance from the ends. 1 shows the main part on the left side of the transformer mounting member 10, the right side of the transformer mounting member 10 is also substantially the same as the screw fastening hole 1.
1, a first notch 12 and a second notch 13 are provided.
Further, although the transformer mounting member 10 having the screwing holes 11 formed therein is shown here, the screwing notch as shown in the conventional example may be provided.

The portion sandwiched by the pair of first cutouts 12 on the upper side and the lower side of the transformer mounting member 10 configured as described above has a reduced vertical cross-sectional area of the plate-shaped body as compared with other portions without cutouts. Therefore, the bending stress in this portion is small. Therefore, even the transformer mounting member 10 having a certain degree of strength can be manually bent at the first notch 12 portion by using a scissors tool such as pliers. Moreover, since the portion with a small stress sandwiched between the pair of first cutouts 12 can be bent in a substantially straight line shape, and distortion is not generated in the surroundings, it is possible to bend easily and accurately in an actual installation site. Can be processed. This is the same when the bending process is performed at the second notch 13 portion.

The shapes of the first notch 12 and the second notch 13 are as follows, if the cross-sectional area of the part sandwiched by the pair of notches on the upper side and the lower side is smaller than the cross-sectional area of the part without other notches.
Any shape may be used. However, since it is easier to perform bending when the difference in cross-sectional area between the cutout portion and the portion without the cutout is made extreme, it is desirable to form the cutout with an angle. Also, since the ease of processing the notch itself differs depending on the equipment etc., the shape may be appropriately changed according to the equipment etc., but the simplest one is the simple straight line as shown in FIG. It is a notch with a notch shape.

The first notch 12 and the second notch 13 are
It is not always necessary to provide it on both the upper side and the lower side of the plate-like body, and only one of the upper side or the lower side may be provided. However, in order to expect a straight and accurate bending process, it is preferable to provide the upper and lower parts respectively. Furthermore, from the viewpoint of reducing the cross-sectional area of the bending target portion of the plate-shaped body, it is not always necessary to provide a notch in the bending target portion, and instead of the notch, a hole substantially similar to the screw fastening hole 11 is provided. It is also possible to form a plurality of holes in the bending target portion. By using both the notch and the screw-fastening hole, the cross-sectional area of the bending target portion is similarly reduced, and the screw-fastening position can be appropriately changed depending on the location.

Further, in the present embodiment, the number of notches is the first
Although the two pairs of the notch 12 and the second notch 13 have been described, by providing three or more pairs, it is possible to realize more flexible bending processing according to the mounting location.

Next, the procedure for bending the transformer mounting member of this embodiment and the case of actually mounting the transformer body on the wall surface will be described. FIG. 2 is a side view of an essential part showing a bending process of a transformer mounting member which is a first embodiment of the present invention, and FIG. 3 is an example of a transformer mounting state by the transformer mounting member which is a first embodiment of the present invention. It is a side view shown.

The procedure for bending the transformer mounting member 10 is as follows.
Although any procedure may be used, here, a case where bending is performed in order from the inside will be described.

As shown in FIG. 2, first, the left and right positions of the pair of first cutouts 12 of the straight plate-shaped body before bending are sandwiched by scissors tools such as pliers, and the two-dot chain line arrow A is used. Bend upwards at an angle of 30 ° to 90 °. Next, the left and right side positions of the pair of second notches 13 are sandwiched by scissors tools such as pliers, and are moved downward by 30 ° as indicated by the two-dot chain line arrow B.
The bending of the left end portion of the transformer mounting member 10 is completed by bending it at an angle of 90 °. In the same procedure, the right end portion, which is the other end portion of the transformer mounting member 10, is bent. In addition, this transformer mounting member 10
In advance, a transformer body (not shown) is fixed by spot welding, screwing or the like.

In order to mount the transformer main body 2 on the wall surface 19 using the transformer mounting member 10 that has been bent, the screw 8 is screwed from the screw fixing hole of the transformer mounting member 10 as shown in FIG. The wall surface 19 is screwed and attached. Although FIG. 3 shows the case where the transformer main body 2 is mounted on the flat wall surface 19, the mounting position is not necessarily limited to the flat wall surface 19.

For example, when the wall surface 19 on which the transformer mounting member 10 is mounted hits a corner, the transformer mounting member 10 is bent and mounted in a shape as shown in FIG.
FIG. 4 is a side view showing another example of a transformer mounting state by the transformer mounting member according to the first embodiment of the present invention.

When the mounting wall surface 19 hits a corner, as shown in FIG.
As shown in, the first notch 12 portion on one end side of the transformer mounting member 10 is left straight without bending, and the bending angle of the second notch 13 portion is adjusted to the wall surface 19. Bend 90 ° to the outside. Transformer mounting member 1
The other end side of 0 is bent as in the procedure shown in FIG. Then, the transformer body 2 can be attached to the wall surface 19 by screwing the screw 8 into the wall surface 19 from the screwing hole. In such a case, it is easier to use the screwing notch than the screwing hole 11.

As described above, the transformer mounting member 10 of this embodiment is fixed to the transformer main body 2 and has a metal plate-like body for mounting the transformer main body 2 at a predetermined position, and an end of the plate-like body. A first notch 1 provided near each end at each bending target portion so that a plurality of the end portions can be bent at a transformer mounting site in accordance with the condition of the transformer mounting position.
2 and a second notch 13 are provided. That is, a plurality of cutouts are provided in pairs on both the upper side and the lower side of the metal rectangular plate-shaped body for mounting the transformer body 2 entirely.

Therefore, the first notch 1 of the plate-shaped body made of metal
Since the cross-sectional area of the second and second cutouts 13 is smaller than that of the other parts without the cutouts and the bending stress is small, even if the transformer mounting member 10 has a certain strength, it can be mounted at the mounting location at the transformer mounting site. The desired bending process that flexibly corresponds to the optimum shape can be performed. Therefore, as in the past,
It is not necessary to perform bending in advance at the time of shipment from the factory, and the equipment and operation of the press machine are no longer necessary in production.
Since it can be mass-produced, it can be provided at a relatively low cost. Further, even when a large number of transformers are installed, the work of transporting them to the site can be made extremely efficient.

Next, a second embodiment of the present invention will be described. FIG. 5 is a plan view showing a main part of a transformer mounting member according to a second embodiment of the present invention.

First, the structure of the transformer mounting member before bending according to this embodiment will be described. As with the first embodiment, the material of the transformer mounting member 20 of this embodiment is also a lightweight metal such as aluminum having a thickness of about 1 to 3 mm or SPCC or SECC so that a transformer having a certain weight can be mounted. A rectangular metal plate made of a steel plate such as the above is used, and as shown in FIG. 5, screw-fastening holes 21 are provided near the ends. A first notch 22 and a second notch 23 are provided at predetermined intervals at opposing positions of the upper side and the lower side that are further inside from the left and right screw fastening holes 21, and 1 notch 2
The second cutout 23 is larger than the second cutout 23. In addition,
The right side of the transformer mounting member 20 is also provided with screw holes 21, a first cutout 22 and a second cutout 23 that are substantially similar.

Therefore, also in the transformer mounting member 20 of this embodiment, the portions sandwiched by the notches on the upper side and the lower side of the transformer mounting member 20 are the same as in the first embodiment.
Since the vertical cross-sectional area is smaller and the bending stress is smaller than that of other portions without notches, bending work can be easily and accurately performed manually at the installation site.

Further, in the transformer mounting member 20 of this embodiment, since the first notch 22 is shallower than the second notch 23, the pair is larger than the cross-sectional area of the portion sandwiched by the pair of first notches 22. The cross-sectional area of the portion sandwiched by the second notches 23 is smaller. That is, the portion sandwiched by the second notches 23 is easier to bend than the portion sandwiched by the first notches 22, and after bending the portion sandwiched by the first notches 22,
By bending the portion sandwiched by the second cutouts 23, when the portion sandwiched by the second cutouts 23 is bent, the effect on the already processed portion is very small.

The shape and position of the notch are not necessarily the same as those in this embodiment, and any shape and position may be used as long as the cross-sectional area is smaller than that of the part without the notch. This is similar to the first embodiment.

Further, as shown in FIG. 6, if a groove-shaped notch 24 is vertically provided between the first notch 22 and the second notch 23, which are paired with the upper side and the lower side, the bending process is further facilitated. Be accurate. FIG. 6 is a perspective view showing a main part of a transformer mounting member according to a third embodiment of the present invention.

In the second and third embodiments, the number of notches is two and the second notch 23 is deeper and deeper than the first notch 22. However, the machining procedure is reversed. In the case of sequentially bending from the second cutout 23, the first cutout 22 may be deeper and deeper than the second cutout 23. Further, if three or more pairs of cutouts are provided, it becomes possible to perform bending work flexibly corresponding to the mounting location.
At that time, the depth of the notch should be shallow according to the processing order, which is the order of bending, such that the notch in the part to be bent first is shallow and the notch in the part to be bent last is deepest. By changing the height, the bending process becomes easier and easier.

Next, the procedure for bending the transformer mounting member 20 of the second and third embodiments will be described. FIG. 7 is a side view of essential parts showing a bending process of the transformer mounting member according to the second and third embodiments of the present invention. In addition,
The bending procedure will be described for the case where the transformer mounting member 20 is sequentially bent from the inside.

As shown in FIG. 7A, first, the right side of the pair of first notches 22 of the straight plate-shaped body before bending is fixed, and the left side position of the first notch 22 is fixed with pliers or the like. Bending tool 2
It is sandwiched by 5 and is moved upward 30 ° to 90 ° as indicated by the double-dashed line arrow C.
Bend to an angle of °. Next, as shown in (b) of FIG. 7, the left side positions of the pair of second cutouts 23 are sandwiched by a bending tool 25 such as pliers, and are moved downward by 30 ° as indicated by a two-dot chain line arrow D.
The bending of the left end portion of the transformer mounting member 20 is completed by bending it at an angle of 90 °. Therefore,
In such a transformer mounting member 20, particularly, when the bending target portion of the second cutout 23 is bent, the bent portion of the first cutout 22 that has already been bent is greatly affected. Less. Transformer mounting member 2 in the same procedure
The right end, which is the other end of 0, is bent. A transformer body (not shown) is also fixed to the transformer mounting member 20 in advance by spot welding, screwing, or the like.

As described above, the transformer mounting member 20 of this embodiment is paired with both the upper side and the lower side of the metal rectangular plate-like body which is entirely made of the same material for mounting the transformer body. The first notch 22 and the second notch 23 having different sizes are provided. That is, the first notch 22 and the second notch 23 of the rectangular metal plate for attaching the transformer body at a predetermined position are different in size according to the bending order, and The size of the notch is such that the notch of the bending target portion that is bent later is larger than the notch of the bending target portion that is bent first.

Therefore, also in the transformer mounting member 20 of this embodiment, as in the first embodiment, the cross-sectional area of the first notch 12 and the second notch 13 of the metal plate-like member has no notches. Since it is smaller than that of the part and the bending stress is small, it is possible to easily and accurately perform bending work according to the situation of the transformer mounting position at the transformer mounting site. Also, in production, there is no need for equipment and operation of a press machine, and mass production is possible, so it can be provided at a relatively low cost, and even when a large number of transformers are installed, the work of transporting to the site can be extremely efficient. .

Moreover, since the size of the first notch 22 and the second notch 23 of the plate-like body is different depending on the bending order, the cross-sectional area of each notch is also different depending on the bending order, and the bending stress is increased. There is a difference in bending, and bending can be done manually by manpower according to the bending order. In particular, since the size of the cutout of the plate-shaped body is made larger than the first cutout 22 of the bending target portion to be bent first, the second notch 23 of the bending target portion to be bent later is made larger. The cross-sectional area of the bending target portion that is bent at a time is larger than the cross-sectional area of the bending target portion that is bent later, and the bending stress of the bending target portion that is bent first is also a notch in the bending target portion that is bent later. Since it is larger than the bending stress of the part, the bending target part that bends later becomes easier to bend than the bending target part that bends first, and the bending part that bends first is affected by the bending process that follows. Do not receive

FIG. 8 is a perspective view showing a transformer mounting state by the transformer mounting member according to the fourth embodiment of the present invention.

As shown in FIG. 8, the transformer mounting member 30 of this embodiment has a first notch 32, a second notch 33,
The third notch 34 and three pairs of notches are formed. In such a transformer mounting member 30, the first notch 3
By appropriately bending the bending target portions of the second cutout 33, the second cutout 33, and the third cutout 34, it is possible to easily cope with an extremely complicated shape. When the screw 8 can be screwed to the wall surface by using the screw hole 31 of the transformer mounting member 30, the screw 8 is inserted into the screw hole 31 to perform the mounting work. If the screw 8 cannot be screwed into the wall surface by using the screw-fastening hole 31 of the transformer mounting member 30, the support plate 40 having the screw-fastening hole 41 is used.
It is also possible to insert the bent portion at the end portion of 0 between the support plate 40 and the wall surface 19 and insert the screw 8 into the screw fixing hole 41 of the support plate 40 to perform the mounting work.

[0047]

As described above, the transformer mounting member according to the first aspect of the present invention is provided with the notch in the vicinity of the end of the metal plate member for mounting the transformer body at a predetermined position. Since the cross-sectional area of the part is smaller than that of the part without other notches and the bending stress is small, even if it is a transformer mounting member with some strength, the desired bending process can be performed manually at the transformer mounting site. Bending suitable for the installation location can be performed. Also in production,
Since there is no need to perform bending in advance, there is no need for equipment or operations such as a press machine, mass production is possible, it can be provided at a relatively low cost, and transportation efficiency to the site when many transformers are installed to some extent Also gets better.

In the transformer mounting member of the second aspect of the present invention, a notch is provided at each of the bending target portions so that a plurality of metallic plate-shaped members for mounting the transformer main body at a predetermined position can be bent at a plurality of positions. Since the cross-sectional area of the cutout portion is smaller than that of the portion without other cutouts and the bending stress becomes small by providing the above, even a transformer mounting member having a certain strength,
At the transformer installation site, multiple bending processes can be performed manually, so it is possible to flexibly adapt to the optimum shape for the installation site. Also, in production, there is no need to perform bending in advance, so there is no need for equipment such as a press machine or operation, mass production is possible, and it is possible to provide it at a relatively low cost. The efficiency of transportation to the site is also improved.

In the transformer mounting member of the third aspect of the present invention, since the size of the notch of the plate-like member differs depending on the folding order, the cross-sectional area of each notch also differs according to the folding order.
The magnitude of the bending stress also differs depending on the bending order, and since bending can be performed manually by the bending order, bending can be facilitated and a complicated shape can be handled.

In the transformer mounting member of the fourth aspect of the present invention, the size of the notch of the plate-shaped body is made larger than the notch of the bending target part to be bent first, and the notch of the bending target part to be bent later. Therefore, the cross-sectional area of the first bending target area is larger than the cross-sectional area of the second bending target area, and the bending stress of the first bending target area is also bent later. Since the bending stress is larger than the bending stress of the notch part of the target part, it is easier to bend the bending target part that bends later than the bending target part that bends first, and the bending part that bends first bends later. Since it is not affected by bending work, bending work becomes easier and it is possible to easily deal with complicated shapes.
