Description

  The present invention relates to a fixture for a housing, a housing, an installation member, and a fixing method.

  When installing the device, usually a fixing tap is made on the housing of the device (a female screw is directly machined on the housing using the tap), and the female screw on the housing is fixed from multiple directions, up, down, left and right. It was fixed to the installation site via screws. Therefore, in such an installation method of the device, it is necessary to perform fixing from a plurality of directions during the fixing operation, the number of fixing screws is increased, and the operation efficiency is extremely poor. In addition, in the installation method, since female screws are provided at a plurality of positions directly on the housing of the device, the tips of the fixing screws project inside the device, and the mounting of a substrate or the like is affected at those portions. This often became a design constraint.

  In order to solve such a problem, Patent Document 1 discloses a device mounting structure that is a housing mounting technology for fastening and fixing a housing of a device or the like of a relay station on a utility pole.

  As shown in FIG. 14, the device mounting structure 100 described in Patent Literature 1 includes a device housing 200 and a mounting device 300 for mounting the device, and fixes the mounting device 300 to an installation location. The housing 200 of the device is installed by fitting the mounting pins 220 and 320 and the slits 230 and 330 provided to each other and fixing the housing 200 of the device to the mounting fixture 300. .

  More specifically, the housing 200 of the device includes two mounting pins 220 protruding outwardly on both sides of the housing side surface (mounting side surface) 210 of the device and lower portions on both sides of the mounting side surface 210. A tapered slit 230 is provided. In addition, the mounting fixture 300 has a substantially J-shaped slit 330 at the upper portion on both sides of the mounting tool side surface (mounting side surface) 310, and projecting mounting pins 320 provided outwardly at the lower portions on both side portions of the mounting tool side surface. Are provided.

  With such a configuration, in the device mounting structure 100 described in Patent Document 1, the mounting pin 220 on the upper side of the housing is aligned with the end surface of the slit 330 on the upper part of the mounting tool 300, and the housing of the device is When the body 200 is slid downward, the mounting pins 220 on the upper side of the housing 200 are inserted into the slits 330 on the upper side of the mounting fixture 300, and the mounting tools are inserted into the tapered slits 230 on the lower side of the housing 200. The mounting pin 320 at the lower part of the side surface of 300 is inserted. At this time, since the slit 230 at the lower side of the side surface of the housing 200 is tapered, the position of the mounting pin 320 on the mounting fixture 300 and the position of the slit 230 on the housing 200 side when the housing 200 is slid downward. Mounting work can be performed without confirming the position.

  However, in the device mounting structure 100 described above, even if the housing 200 of the device is locked and hung by the mounting fixture 300, the housing 200 has some play in the front, rear, left, and right directions with respect to the mounting fixture 300. In addition, there is a problem that the housing 200 is difficult to fix because the housing 200 moves in an unstable manner when the housing 200 is fixed. Further, in the above-described device mounting structure 100, a female screw (not shown) provided on the lower surface of the housing 200 is screwed via the mounting portion 340 of the mounting fixture 300. For this reason, the tip of the fixing screw protrudes into the inside of the device at one location, and there remains a problem that is a constraint on the design of the device.

  Therefore, an object of the present invention is to provide a fixing device and a fixing method in which the device is securely temporarily fixed to the installation metal only by fitting the housing of the device and the installation metal to each other.

  The fixing device of the present invention includes a housing of the device, a mounting bracket for attaching the housing to an installation location, and a holding bracket for fixing the housing to the mounting bracket, wherein the housing includes the mounting bracket. The mounting bracket has a mounting surface to be mounted, and a protruding portion in which a diameter of a protrusion provided on the mounting surface gradually changes.

The height may be any height that can be set.
[Configuration of installation bracket]
FIG. 3 is a schematic diagram showing the mounting receiving surface 35 and the slit 32 of the mounting bracket 3 according to the first embodiment of the present invention. As shown in FIG. 3, the mounting bracket 3 is bent at a right angle so that the mounting bracket 3 comes into contact with a wall when the mounting bracket 3 is installed on a wall, for example, and two YZ planes are formed on both sides of the main body 31. Each of the mounting receiving surfaces 35 has slits 32a and 32b formed in a substantially J shape at one end and the other end of the mounting receiving surface 35 in the Z direction. Each of the mounting receiving surfaces 35 has a cutout portion other than the slits 32a and 32b, and a cutout surface 36 is formed smoothly up to the slit at the other end. In addition, the mounting bracket 3 has a female screw portion 33 for screwing the holding bracket 5 at one end of each mounting receiving surface 35.

In the present embodiment, the shape of the slit 32 is substantially J-shaped, but is not limited thereto, and may be substantially U-shaped. Further, in the present embodiment, the female screw portion 33 for screwing the holding metal member 5 is provided at one end of each of the mounting receiving surfaces 35. However, the present invention is not limited thereto. The female screw portion 33 may be provided at any position of the installation bracket 3 as long as the female screw portion 33 can be fixed so as to be pressed into the slit 32. The holding metal 5 may be fixed to the mounting metal 3 by a method other than screwing, for example, by using a fitting mechanism.
[Structure of holding bracket]
The holding member 5 includes a main body 51 formed in a strip shape having the same length as the X direction of the mounting bracket 3, and a tapered portion 22 of the housing 2 opposed to the slit 32 a of the mounting bracket 3 at both ends of the main body 51. And a slit 52 formed in a substantially U shape so as to be sandwiched therebetween. In addition, the holding metal member 5 includes a female screw portion 53 at a position corresponding to the female screw portion 33 provided on the installation metal member 3, and the female screw portion 33 and the female screw portion 53 are screwed with a male screw. , Fixed to the mounting bracket 3. In the present embodiment, the shape of the main body 51 of the holding metal member 5 is a belt shape. However, the present invention is not limited to this. It may have a shape, and may have a substantially U-shaped slit 52 without a main body portion 51 and a female screw portion 53 which are integrated.
[Installation procedure]
The procedure for attaching the housing 2 of the apparatus to the mounting bracket 3 will be described with reference to FIGS. Here, the Z direction is the up-down direction, the Y direction is the front-back direction, and the X direction is the left-right direction.

  First, the mounting bracket 3 is installed at an installation place such as a wall using screws or bolts. Next, as shown in FIG. 4, the upper taper portion 22 a provided on the mounting surface 21 of the housing 2 is aligned with the upper slit 32 a provided on the mounting receiving surface 35 of the mounting bracket 3, and the housing 2 is mounted. Slide down. At this time, even if the slit 32b at the lower part of the mounting surface 35 of the mounting bracket 3 and the tapered portion 22b at the lower part of the mounting surface 21 of the housing 2 are slightly displaced, the mounting surface 35 is notched and the lower part is cut off. Since the cutout surface 36 is formed up to the slit 32b, the lower tapered portion 22b can be easily fitted into the lower slit 32b by the weight of the housing 2.

  When all the tapered portions 22 of the housing 2 are fitted into the corresponding slits 32 of the mounting bracket 3, as shown in FIG. 5, the tapered portions 22 and the slits 32 are locked at the same diameter. Then, the housing 2 is securely temporarily fixed to the mounting bracket 3. At this time, since the housing 2 has the tapered portion 22 formed in a tapered shape, it must be temporarily fixed in the front-rear and left-right directions other than the up-down direction regardless of the state temporarily fixed to the mounting bracket 3. Can be.

  Finally, as shown in FIG. 6, the holding metal 5 is lowered from above so that the slits 52 at both ends of the holding metal 5 are aligned with the slits 32 a of the mounting metal 3, and the female screw provided on the upper part of the mounting metal 3. The portion 33 and the female screw portion 53 of the holding member 5 are screwed with fixing screws. In this manner, the respective tapered portions 22 of the housing 2 are fitted and temporarily fixed to the corresponding slits 32 of the installation metal fitting 3, and the tapered portion 22 a is pressed and fixed by the slit 52 of the holding metal 5, so that Finally, the housing 2 is also fixed in the vertical direction, and the housing 2 can be completely fixed.

  According to the present embodiment, the tapered portions 22 a and 22 b are provided on the mounting surface 21 of the housing 2, and the tapered portions 22 a and 22 b are fitted to the slits 32 a and 32 b provided on the mounting receiving surface 35 of the mounting bracket 3. With this configuration, the casing 2 can be completely fixed to the mounting bracket 3 in a direction other than the vertical direction only by sliding the housing 2 downward and locking the mounting bracket 3. Furthermore, in order to fix so that the taper part 22 of the housing 2 fitted to the slit 32 of the installation metal fitting 3 is pressed by the slit 52 of the holding metal fitting 5, the holding metal fitting 5 is simply screwed to the installation metal fitting 3. The housing 2 can be completely fixed. Therefore, the number of locations required for fixing the device can be reduced, and the fixing operation can be performed in only one direction from above, so that the work efficiency of the worker can be improved.

  According to the present embodiment, since the notch surface 36 is formed in the mounting receiving surface 35 of the mounting bracket 3, when the worker mounts the housing 2 on the mounting bracket 3, the lower tapered portion 22 b and the lower tapered portion 22 b are formed. Work can be performed without confirming the positional relationship with the slit 32b.

According to the present embodiment, since the housing 2 can be completely fixed to the mounting bracket 3 without directly forming a female screw in the housing 2 of the device, the fixing screw is provided inside the device. Since the tip of the device does not protrude, it does not affect the mounting of the substrate inside the device, so that restrictions on the design of the device can be avoided.
[Modification 1]
As a first modification of the first embodiment, as shown in FIG. 7, instead of the substantially U-shaped slits 52 provided on both ends of the holding member 5, as shown in FIG. The slit 52a having a structure for pressing the slit 22a may be used.
[Modification 2]
In the first embodiment, the tapered portion 22 of the housing 2 is fitted into the slit 32 of the mounting bracket 3 to temporarily fix the housing 2 to the mounting bracket 3. On the other hand, as a modified example 2 of the first embodiment, the housing 2 is temporarily fixed to the mounting bracket 3 by fitting the projection 222 to the slit 32 instead of the tapered portion 22.

  8 and 9, the shape of the protrusion 222 is tapered for convenience of description of the protrusion 222. However, any shape having a cut surface that satisfies the requirements of the protrusion 222 described later may be used. Good.

  FIG. 8 is a diagram illustrating a projection 222 formed when the center line is formed to be substantially perpendicular to the mounting surface 21 of the housing 2. FIG. 8 shows a top view of the state in which the protrusion 222 of the housing 2 is placed in the recess 321 of the slit 32 and a view of a cut surface with respect to a plane parallel to the slit 32 at the position of the recess 321 in this state. .

  FIG. 9 is a diagram illustrating a projection 222 having a center line inclined from a right angle with respect to the mounting surface 21 of the housing 2. FIG. 9 shows a top view of the state in which the protrusion 222 of the housing 2 is placed in the recess 321 of the slit 32, and a view of a cut surface with respect to a plane parallel to the slit 32 at the position of the recess 321 in this state. . Here, the center line of the protruding portion 222 is formed to be inclined from a right angle with respect to the mounting surface 21 of the housing 2. It may be formed at an angle.

  8 and 9, the orthogonal projection of a cut surface to a plane parallel to the slit 32 will be described by taking a pair of protrusions 222 as an example. Here, a pair of projections 222 that are a pair are, for example, two projections that are provided on the opposed mounting surfaces 21 of the housing 2 and whose directions with respect to the respective mounting surfaces 21 are opposite to each other. 222, or two protrusions 222 provided only on the mounting surface 21 on one side of the housing 2 so that the directions are opposite to each other. That is, in FIGS. 8 and 9, a pair of projecting portions 222 are provided so as to be convex on the right side toward the front of the housing 2 and convex on the left side in the opposite direction. I have.

  In a pair of protrusions 222 as shown in FIGS. 8 and 9, the position where the protrusion 222 contacts the concave portion 321 of the slit 32 is defined as a predetermined position ss ′, and the predetermined position ss ′ is defined as Positions parallel to the position ss ′ near both sides as the center are defined as positions aa ′ and bb ′, respectively. At positions aa ', bb', and ss ', orthogonal projections of the cut plane on the corresponding slit 32 in a plane parallel to the corresponding slit 32 are respectively orthogonal projections AA', BB. 'And SS.

  In the pair of protrusions 222, the protrusions provided in the vicinity of predetermined positions located on the opposite sides with respect to the respective predetermined positions ss', that is, the protrusions provided on the left side in FIG. The orthogonal projection BB ′ at the position bb ′ between the portion 222 and the protrusion 222 provided in the convex shape on the right side respectively forms the common point P in the concave portion 321 of the corresponding slit 32, Each portion other than the concave portion 321 has a common point P ′.

  The shape of the cross section of the protrusion 222 in Modification 2 as described above is arbitrary, but a specific example will be described. For example, as shown in FIG. 10, a straight line passing through two contact points of the protrusion 222 and the recess 321 at a predetermined position s-s 'is defined as a straight line cc'. Note that, depending on the shape of the protrusion 222, a case where there are three or more contacts is also assumed. In that case, consider all combinations that include only two of those three or more contacts. Then, the maximum combination is selected from the lengths of the line segments having both ends of the two contacts forming the combination, and the straight line passing through the two contacts of the combination is defined as the straight line cc '.

  Further, the distance between the intersection of the straight line cc 'and the orthogonal projection of the cut surface of the projection 222 onto the slit 32 by a plane parallel to the slit 32 is referred to as the section intersection distance here. Note that, depending on the shape of the protrusion 222, there may be a case where there are three or more intersections. In that case, consider all combinations that include only two of the three or more intersections. Then, the maximum combination is selected from the lengths of the line segments having the two intersections forming the combination at both ends, and the length of the line segment passing through the two intersections of the combination is defined as the cross-section intersection interval. .

  At this time, the protrusion 222 may have a shape in which the cross-section interval monotonically changes as the distance from the mounting surface 21 increases. Further, the protrusion 222 corresponds to the cut surface in the vicinity of both sides of a predetermined position ss ′ in contact with the slit 32 (for example, between positions aa ′ to position bb ′ in FIG. 8 or FIG. 9). Such a monotonous change in the cross-section intersections can sufficiently exhibit the effects of the present invention described above, but does not prevent the cross-section intersections corresponding to the cut surface from changing over the entire area other than the vicinity.

  The mounting position of the protrusion 222 in Modification 2 will be described with a specific example. As shown in FIG. 11, there is a case where one is provided on each of the mounting surfaces 21 on both sides of the housing 2. As shown in FIG. 12, one protrusion 222 is provided above the mounting surface 21 on one side of the housing 2, and one protrusion 222 is provided below the mounting surface on the other side. The projection 223 may be provided at a position corresponding to the projection 222. The protruding portion 223 may be any shape as long as it can simply support the housing 2 by being inserted into the slit 32 of the mounting bracket 3. Further, as shown in FIG. 13, two protrusions 222 may be provided on one mounting surface 21 of the housing 2 and two support portions 223 may be provided on the other mounting surface 21.

  In the second modification, since at least two protrusions 222 are provided on the housing 2, the housing 2 can be temporarily fixed to the mounting bracket 3 in all the examples shown in FIGS. 11 to 13. Here, in consideration of the stability of the temporary fixing, the stability at the time of temporary fixing improves with the modification shown in FIG. 9 and the modification shown in FIG. The stability at the time of temporary fixing is the best when at least two protrusions 222 (tapered portions 22) formed in a tapered shape are provided on each mounting surface 21 of the housing 2.

By forming the protrusion 222 in a tapered shape and forming the taper 22 in this manner, the manufacture of the protrusion 222 is facilitated, and the manufacturing cost can be reduced.
(2) Second Embodiment A second embodiment will be described with reference to the drawings. FIG. 14 is a schematic view showing the fixing device 10 according to the second embodiment of the present invention.

In the first embodiment, the upper taper portion 22a is fixed by the slit 52 of the holding member 5, whereas in the second embodiment, the holding member 15 is configured to slide and the lower portion is formed.

Prepare. This gap is formed so that its length is the same as the length from the mounting receiving surface 35 of the mounting bracket 13 to a slide hole 133 described later.

  The mounting bracket 13 includes a main body 131, a slide hole 133 formed in the main body in a rectangular shape adjacent to the lower slit 32b, and a tap portion 134 provided at a lower portion of the slide hole 133 so as to be bent at a right angle. And a bush 137 provided on the back surface of the main body so as to form a gap between the main body 131 and the installation location.

The screw 7 is formed such that the diameter of the cylindrical portion 72 below the head 71 is smaller than the diameter of the screw portion 73, as shown in FIG.
[Assembly of slide mechanism]
As shown in FIG. 15, the female screw portion 154 of the holding member 15 is inserted into the slide hole 133 from the back side of the main body 131 of the setting member 13, and the slit 152 of the holding member 15 is outside the mounting receiving surface 35 of the setting member 13. To follow. Thereafter, as shown in FIG. 17, the tap portion 134 provided below the slide hole 133 and the female screw portion 154 of the holding metal 15 inserted from the slide hole 133 are screwed from below the installation metal 13 with the screw 7. Screw it. At this time, all the screw portions 73 of the screw 7 are turned up to the upper side of the tap portion 134 of the mounting bracket 13 so that the screw 7 does not fall off. By doing so, the screw part 73 is hooked on the tap part 134 of the mounting bracket 13, so that the holding bracket 15 can also be temporarily fixed at a predetermined position, and the holding bracket 15 does not fall. In this manner, as shown in FIG. 18, the slit 152 of the holding metal 15 is temporarily fixed slightly above the lower slit 32 b of the installation metal 13, and the holding metal 15 is lowered by tightening the screw 7 from below. Can be slid.
[Installation procedure]
