Description

  The present invention relates to a substrate guide spacer, an apparatus using the substrate guide spacer, and a method of manufacturing the apparatus.

  In various devices such as a power supply device and a power conditioner device, it is necessary to fix a substrate on which electronic components and the like are mounted in a housing. Conventionally, a board supporting part for processing a plate material constituting a casing and supporting the board has been provided. The substrate support portion is manufactured by cutting and bending the plate material constituting the housing 20, and is composed of two L-shaped members 51 and 52 as shown in FIG. . By changing the folding position of the plate material between the L-shaped member 51 and the L-shaped member 52, a gap having a width (t) substantially equal to the thickness of the substrate 30 fixed in the housing is obtained.

  Then, as shown in FIG. 8, one end of the substrate 30 is held by the L-shaped members 51, 52 by inserting one side of the substrate 30 into the gap between the L-shaped members 51, 52. Thereafter, the other side of the substrate 30 is screwed to the housing 20 using a fixing bracket provided with screw holes. Thereby, the substrate 30 is fixed in the housing 20.

  In addition, a spacer component 1 including a cylindrical portion 5 in which a hollow hole 5a is formed and a non-circular head 3 is disclosed as a component for fixing a substrate to a plate material (see Patent Document 1). In the spacer component 1, the head 3 is pushed into the outer case 2 and fixed, and a screw is screwed into the hollow hole 5 a of the cylindrical part 5 to screw the substrate to the cylindrical part 5.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each figure, the component which has an equivalent function is attached | subjected the same code | symbol, and detailed description of the component of the same code | symbol is not repeated.

  First, the structure of the substrate guide spacer according to the embodiment of the present invention will be described. FIG. 1 is a perspective view of a substrate guide spacer 10 according to an embodiment of the present invention. The substrate guide spacer 10 includes a cylindrical body 11, a groove provided on the upper surface of the cylindrical body 11, a support groove 13 for supporting the substrate, and an insertion portion provided continuously with the lower surface of the cylindrical body 11. 12.

  As shown in FIG. 1, the support groove 13 is provided as a rectangular shape, and more specifically, two flat grooves provided so as to be orthogonal to the upper surface of the cylindrical body 11 and parallel to each other. It has a side surface 13a and a bottom surface 13b that connects these two side surfaces 13a. The distance between the two side surfaces 13a is substantially equal to the thickness of the substrate to be attached.

  The insertion portion 12 is a portion that is press-fitted into a mounting hole of the housing, and has a protrusion 12a and a protrusion 12b made of a material harder than the housing (for example, stainless steel). More specifically, the insertion portion 12 is connected to the lower surface of the cylindrical body 11 and has a smaller diameter than the cylindrical body 11 (hereinafter referred to as “insertion cylindrical body”), and the side surface of the insertion cylindrical body. A plurality of protrusions 12a provided so as to extend radially in a plane orthogonal to the press-fitting direction, and a reverse-tapered protrusion 12b connected to the lower surface of the insertion portion cylinder.

  Thus, the protrusion 12a is formed so that the cross-sectional shape in a plane orthogonal to the direction in which the insertion portion 12 is press-fitted is convex toward the outside of the insertion portion 12, and the protrusion 12b A cross-sectional shape in a plane parallel to the press-fitting direction is formed to be convex toward the outside of the insertion portion 12.

Next, a method for manufacturing an apparatus including a substrate supported by the substrate guide spacer 10 according to the present embodiment will be described.
(1) First, as shown in FIG. 2 (1), a circular attachment hole 20 a is formed in a predetermined part of the housing 20. The diameter of the mounting hole 20a is, for example, substantially the same as the diameter of the bottom surface of the protrusion 12b.
(2) Next, as can be seen from FIG. 2 (1) and FIG. 4, the insertion portion 12 is positioned above the attachment hole 20 a and the direction of the support groove 13 coincides with the attachment direction of the substrate 30. The substrate guide spacer 10 is placed on the housing 20. When the diameter of the mounting hole 20a is substantially equal to the diameter of the bottom surface of the protrusion 12b, the substrate guide spacer 10 is easily set along the mounting hole 20a.
(3) Next, as shown in FIGS. 2 (1) and 2 (2), the pressing member 100 is brought into contact with the upper surface of the cylindrical body 11 to apply pressure to the substrate guide spacer 10. Is inserted into the mounting hole 20a.

  FIG. 3 is a perspective view of the substrate guide spacer 10 attached to the housing 20. A distance d in FIG. 3 is a distance between the bottom surface 13 b of the support groove 13 and the inner wall of the housing 20, and indicates an insulation distance between the substrate 30 fixed in the housing 20 and the housing 20. The insulation distance is preferably set to a predetermined value according to the apparatus specification. However, according to the substrate guide spacer 10, the insulation groove 13 can be insulated by changing the depth of the support groove 13 and / or the height of the cylindrical body 11. The distance can be adjusted freely.

  Here, the mechanism by which the substrate guide spacer 10 is fixed to the housing 20 will be described in detail. Since the protrusions 12 a and 12 b are made of a material harder than the casing 20, the protrusion 12 a crushes the casing 20 by applying pressure to the substrate guide spacer 10 with the pressing member 100, so that the mounting holes of the casing 20 are attached. The metal around 20a plastically flows in accordance with the shape of the projections 12a and 12b of the insertion portion 12. As a result, the gaps between adjacent protrusions 12a and between the protrusions 12a and 12b are filled with the metal of the housing 20. Thus, since the metal of the housing 20 fills the space between the protrusions 12 a, the substrate guide spacer 10 does not rotate around the central axis of the cylindrical body 11. In addition, since the metal of the housing 20 fills the periphery of the reverse taper-shaped protrusion 12 b, the substrate guide spacer 10 is difficult to come out of the housing 20.

(4) Next, as shown in FIG. 4, one side of the substrate 30 is inserted into the support groove 13 of the substrate guide spacer 10. Thereby, the substrate guide spacer 10 supports one end of the substrate 30. Thereafter, the other side of the substrate 30 is fixed to the housing 20. One end of a coupling member (for example, a fixing bracket bent in an L shape) is screwed to the substrate 30, and the other end of the coupling member is screwed to the housing 20. Alternatively, the substrate 30 may be screwed to the bottom surface of the housing 20 with a spacer interposed between the back surface of the substrate 30 and the bottom surface of the housing 20.

  The apparatus manufactured through the above process includes a housing 20 provided with an attachment hole 20a, a substrate guide spacer 10 in which the insertion portion 12 is press-fitted into the attachment hole 20a of the housing 20, and a substrate guide spacer 10. And a substrate 30 having one side inserted into the support groove 13.

  As described above, according to the present embodiment, the substrate guide spacer 10 can be fixed to the housing 20 without forming a notch in the housing. Even if it is provided near the end, the strength of the housing 20 does not decrease. Furthermore, since one side of the substrate 30 can be attached to the housing 20 without screwing, the manufacturing efficiency of the device can be improved.

  Further, when the substrate guide spacer 10 according to the present embodiment is press-fitted into the mounting hole 20a of the housing, the metal around the mounting hole 20a plastically flows in accordance with the shape of the protrusion 12a of the insertion portion 12, The substrate guide spacer 10 attached to the housing 20 does not rotate around the central axis of the cylindrical body 11. That is, the direction of the support groove 13 does not change after press-fitting. This eliminates the need to adjust the direction of the support groove 30 when inserting one side of the substrate 30 into the support groove 13 and facilitates the work of attaching the substrate 30.

  Further, according to the present embodiment, even when the size of the substrate 30 is changed, it is possible to cope with the case by changing the depth of the support groove 13 without changing the height of the cylindrical body 11.

  In the above-described apparatus manufacturing method, a plurality of substrate guide spacers may be simultaneously press-fitted into the casing to increase manufacturing efficiency. In this case, in the step of forming the attachment holes 20a, a plurality of attachment holes 20a are formed in a straight line in the housing 20 based on the attachment position of the substrate 30. In the step of placing the substrate guide spacer 10 on the housing 20, the substrate guide spacer 10 is placed on each of the plurality of attachment holes 20 a formed in the housing 20. In the step of press-fitting the substrate guide spacer 10, a pressing member having a width equal to or larger than the width of the substrate 30 is prepared, and the pressing member is placed on the upper surfaces of the plurality of substrate guide spacers 10 placed on the housing 20. A plurality of substrate guide spacers 10 are press-fitted simultaneously by applying pressure by abutting. According to such a manufacturing method, since a plurality of substrate guide spacers are simultaneously press-fitted into the housing by a single pressure application step, the manufacturing efficiency can be further increased.

(Modification of spacer for substrate guide)
Next, substrate guide spacers 10A, 10B, and 10C according to three variations of the substrate guide spacer 10 will be described.

  First, the substrate guide spacers 10A and 10B will be described with reference to FIGS. The difference between the substrate guide spacers 10A and 10B and the substrate guide spacer 10 described above is the structure of the support groove.

  As shown in FIG. 5A, the support groove 14 of the substrate guide spacer 10A has two side surfaces 14a facing each other and a bottom surface 14b connecting the two side surfaces 14a. Each side surface 14a is formed so as to rise in a kamaboko shape from the upper end and the lower end of the side surface 14a toward the center. The distance between the side surfaces 14a becomes narrower at first as it advances from the upper surface of the cylindrical body 11 in the depth direction of the groove, becomes the narrowest at the approximate center of the side surface 14a, and then becomes wider.

  By providing such a support groove 14, when one side of the substrate 30 is inserted into the support groove 14, the semi-cylindrical protrusion on the side surface 14 a is deformed according to the thickness of the substrate 30. As a result, the substrate 30 is held by the support groove 14 so as not to slightly move in the direction orthogonal to the direction of the support groove 14 (thickness direction of the substrate 30).

  Note that a kamaboko-shaped protrusion may be provided only on one of the two side surfaces of the support groove. That is, the protrusion on one of the two side surfaces may be raised, and the other side surface may be a flat side surface like the above-described side surface 13a.

  In addition, the tops of the semi-cylindrical projections on the two side surfaces 14a are not limited to being provided at the same depth of the support groove as shown in FIG. It may be.

  Next, a substrate guide spacer 10B according to a second modification will be described. As shown in FIG. 5B, the support groove 15 of the substrate guide spacer 10B has a first side surface 15a and a second side surface provided so as to be orthogonal to the upper surface of the cylindrical body 11 and parallel to each other. 15b and a bottom surface 15c connecting the first and second side surfaces 15a and 15b. Both the first side surface 15a and the second side surface 15b are provided as flat surfaces, like the above-described side surface 13a. The second side surface 15b is formed from the upper surface of the cylindrical body 11 to a deeper position than the first side surface 15a. The bottom surface 15c is not limited to a curved surface as shown in FIG.

  As shown in FIG. 5B, the bottom surface 15c is connected to the lower end 15a1 of the first side surface 15a, gradually approaches the second side surface 15b while drawing a curved surface, and finally the lower end 15b1 of the second side surface 15b. Connect with.

  By providing such a support groove 15, when one side of the substrate 30 is inserted into the support groove 15, one surface of the substrate 30 is in surface contact with the second side surface 15 b, and the corner of the other surface of the substrate 30. Hits the bottom surface 15 c, and the bottom surface 15 c is deformed in accordance with the corner shape of the substrate 30. As a result, the substrate 30 is held by the support groove 15 so as not to slightly move in the direction orthogonal to the direction of the support groove 15 (the thickness direction of the substrate 30).

  According to the substrate guide spacers 10A and 10B described above, the same effect as the substrate guide spacer 10 can be obtained, and the substrate 30 is gripped so as not to slightly move in the thickness direction. Can be improved.

  In the substrate guide spacer 10, the bottom surface 13 b may be configured to have a shape (V shape, arc shape, or the like) in which the width of the support groove becomes narrower as it goes in the depth direction of the support groove. Even in the case of such a groove shape, the substrate 30 can be gripped so as not to be finely moved in the thickness direction by the two corners of the front side and the back side of one side of the substrate 30 abutting against the bottom surface 13c.

  Next, a substrate guide spacer 10C according to a third modification will be described with reference to FIGS.

  As shown in FIG. 6A, the substrate guide spacer 10 </ b> C further includes a support base 16 having a support surface 16 a that is flush with one of the two side surfaces 13 a of the support groove 13.

  A process of attaching the substrate 30 to the housing 20 via the substrate guide spacer 10C will be described with reference to FIG. As shown in FIG. 6B, the substrate guide spacer 10C is fixed to the housing 20 so that the support surface 16a faces upward. Then, one side of the substrate 30 is inserted into the support groove 13 of the substrate guide spacer 10C. At this time, first, one end of the substrate 30 is placed on the support surface 16 a protruding toward the inside of the housing 20, and then the substrate 30 is slid along the support surface 16 a and inserted into the support groove 13.

  Thereby, the board insertion process can be further facilitated. Moreover, since the support surface 16a of the support stand 16 supports the board | substrate 30 from the bottom, the board | substrate 30 can be attached more stably.

  In addition, you may provide a support stand not only in said support groove 13 but in the support grooves 14 and 15 of the shape demonstrated in Fig.5 (a), (b).

  The substrate guide spacers according to the embodiment and the modification of the present invention have been described above. The cylindrical body 11 provided with the support grooves is not limited to this shape, and may be a columnar body of a polygonal column such as an elliptical column or a quadrangular column. Moreover, about the protrusion of the insertion part 12, the protrusion 12b may be abbreviate | omitted and only the protrusion 12a may be provided.

(Modification of device manufacturing method)
Next, a modification of the device manufacturing method according to the embodiment of the present invention will be described. In the above-described apparatus manufacturing method, the substrate guide spacer is fixed to the housing in a state in which the direction of the support groove is aligned with the mounting direction of the substrate. A support groove is formed when the substrate guide spacer is press-fitted into the housing using the pressing member having the protrusions.

  A method for manufacturing an apparatus according to this modification will be described with reference to FIGS.

(1) First, as shown in FIG. 7A, a substrate guide spacer 90 having no support groove is prepared. The substrate guide spacer 90 has the same configuration as the substrate guide spacer 10 except that no support groove is formed, and includes a columnar body 11 and an insertion portion 12 provided continuously with the lower surface of the columnar body 11.
(2) Next, a circular attachment hole is formed in a predetermined part of the housing 20. The diameter of the mounting hole is substantially the same as the diameter of the aforementioned insertion portion cylinder.
(3) Next, the substrate guide spacer 90 is placed on the housing 20 so that the insertion portion 12 is positioned on the mounting hole of the housing 20.
(4) Next, the pressing member 200 is prepared. As shown in FIGS. 7A and 7B, the pressing member 200 is provided with a main body 201 having a flat surface 201a, and a thickness substantially equal to that of the substrate 30 provided so as to be orthogonal to the surface 201a. And a flat projection 202 having the same. The protrusion 202 is made of a material harder than the cylindrical body 11.
(5) Next, as can be seen from FIG. 7B, the protrusion 202 of the pressing member 200 is brought into contact with the upper surface of the cylindrical body 11 to apply pressure to the substrate guide spacer 90, and the lower surface of the pressing member 200. The substrate guide spacer 90 is pushed into the mounting hole of the housing 20 until 201 a contacts the upper surface of the cylindrical body 11. Thus, the insertion portion 12 of the substrate guide spacer 90 is press-fitted into an attachment hole formed in the housing 20, and a support groove for supporting the substrate 30 is formed on the upper surface of the cylindrical body 11.
(6) Thereafter, in the same manner as described with reference to FIG. 4, one side of the substrate 30 is inserted into the support groove formed by applying the pressure of the substrate guide spacer 90.

  According to the manufacturing method of the apparatus according to the present modification, it is not necessary to adjust the direction of the support groove so as to coincide with the mounting direction of the substrate when the substrate guide spacer is placed on the housing. Since the support groove is formed while being press-fitted into the housing, the manufacturing efficiency can be further increased.

  Note that by using the pressing member 200 having the protrusion 202 having a width longer than the width of the substrate, it is possible to simultaneously form the support grooves of the plurality of substrate guide spacers 90.

  In this case, in the step of forming attachment holes in the housing 20, a plurality of attachment holes are formed in a straight line based on the attachment position of the substrate 30. In the step of placing the substrate guide spacer 90 on the housing 20, the substrate guide spacer 90 is placed on each of the plurality of attachment holes. Then, as the pressing member 200, a projection member 202 having a width equal to or larger than the width of the substrate is prepared, and in the pressure applying step by the pressing member 200, the pressing member 200 is placed on the upper surface of the columnar body 11 of the plurality of substrate guide spacers 90. The protrusions 202 are brought into contact with each other, and pressure is applied to the plurality of substrate guide spacers 90.

  According to such a method, not only a plurality of substrate guide spacers are simultaneously press-fitted into the housing by a single pressure application step, but also a plurality of support grooves are formed so as to be aligned in a straight line with high accuracy. be able to.
