Moreover, since the shim member has a spring property, it can have a restoring property.

  Hereinafter, the present invention will be described in detail with reference to examples.

  FIG. 1 shows an external appearance of a bisected casing portion of a communication device having a unit structure according to an embodiment of the present invention before the coupling. The communication device 10 includes a case 13 having a wall portion 12 having a predetermined height perpendicular to each side of the square bottom plate 11, and a predetermined shape perpendicular to each side of the upper plate 14 and the upper plate 14. A cover 16 having a wall portion 15 having a height of 5 mm is provided. A shim 18 formed by connecting five Z-shaped portions 17 to each other is attached to the wall portion 12 of the case 13 in a state where the shim 18 is positioned by a positioning pin 19 planted on the upper end portion of the wall portion 12. . In the present embodiment, the bottom plate 11 is a square having a side of 50 mm, and the wall portions 12 and 15 are both formed of a sheet metal or die cast having a thickness of about several mm.

  FIG. 2 shows a state where the communication device is disassembled. Two positioning pins 19 are implanted at the upper end of the wall portion 12 of the case, two for each wall surface. A positioning hole 21 into which the pin 19 is fitted is formed at a corresponding position in the lower end portion of the wall portion 15 of the cover. The shim 18 connects five Z-shaped portions 17, and in the present embodiment, a total of four are used for each side. The shim 18 is provided with two through holes 22 for passing the positioning pins 19. Although not shown, the substrate 23 has a high-frequency circuit disposed at least in part.

  FIG. 3 shows the positional relationship of the shim with respect to the cover and the case, and FIG. 4 is an enlarged view of a portion surrounded by a broken line 24 in FIG. 5 and 6 are views of the shim of this embodiment viewed from the upper side or the lower side. As apparent from FIGS. 5 and 6, the shim 18 is formed by connecting the Z-shaped portion 17 whose section is bent in a Z-shape with the connecting portion 25 integrally connected to the central portion 25A. This is a punched metal plate made of nickel, chrome, iron alloy, Inconel (registered product), etc. The Z-shaped portion 17 is bent into a shape as shown in these drawings. The connecting portion 25 has two long holes per shim 18, and these constitute a through hole 22.

  As shown in FIG. 4, the shim 18 is temporarily fixed on the wall portion 12 by passing the positioning pins 19 of the case 13 through the respective through holes 22. The through hole 22 is slightly larger than the thickness of the pin 19, and the lower piece portion 27 bent downward in the Z-shaped portion 17 is in light contact with or separated from the wall portion 12 in this state. The length of the shim 18 is equal to each side of the wall portion 12.

  As shown in FIGS. 3 and 4, the upper piece 28 constituting the upper portion of the Z-shaped portion 17 of the shim 18 has a shape that expands by a predetermined amount outward from the wall portion 12 of the case 13. . Accordingly, a square having four corners at the intersections of four straight lines connecting the same height positions of the upper piece 28 of the shim 18 rather than a square formed when the wall 15 is cut in parallel with the cover 16. Therefore, the wall portion 15 of the cover 16 can be easily positioned with respect to the respective shims 18 when the cover 16 is attached to the case 13.

  FIG. 7 shows the change of the shape of the shim when the cover is attached to the case with the passage of time. FIG. 4A shows an initial state in which a shim 18 is attached between the upper end portion of the case wall portion 12 and the lower end portion of the cover wall portion 15 by a pin not shown in the drawing. Yes.

  FIG. 4B shows a case where the lower end portion of the wall portion 15 of the cover is brought into contact with the central portion 25A of the shim, and the lower end portion of the wall portion 15 is brought closer to the upper end portion of the wall portion 12 of the case in this state by a predetermined distance. It represents. Since the shim 18 is made of a material rich in elasticity, the upper end portion 28A and the lower piece shown by the arrows of the upper piece portion 28 as the inclination angle of the central portion 25A becomes more horizontal than in FIG. The lower end portion 27A indicated by the arrow of the portion 27 approaches the corresponding wall portions 15 and 12, respectively.

  FIG. 4C shows a state in which the lower end portion of the wall portion 15 of the cover is further pressed against the upper end portion side of the wall portion 12. The upper end portion 28A of the upper piece portion is pressed against the wall portion 15 of the cover, and the lower end portion 27A of the lower piece portion is pressed against the wall portion 12 of the case. Finally, the lower piece 27 and the upper piece 28 bend together as shown in FIG. At this time, due to the spring property of the shim 18, the lower end portion 27A gives a force to lift the case wall portion 12 in pressure contact with the upper end portion 28A, and the upper end portion 28A presses the wall portion 15 of the cover in pressure contact therewith. Gives downward force. As a result, the upper end surface of the wall portion 12 of the case and the lower end surface of the wall portion 15 of the cover are always in pressure contact via the central portion 25A of the shim.

  The shim 18 is thin, and is pressed against the cover wall 15 and the case wall 12 at the central portion 25A without any gap. Further, the lower piece 27 and the upper piece 28 of the shim are arranged so as to cover the walls 12 and 15 from the inside or the outside. Therefore, not only the electrical contact between the case 13 and the cover 16 is kept good at these joints, but also an electromagnetic shielding function for preventing leakage of radio waves can be exhibited well.

  By the way, in the communication device 10 of the present embodiment, the bottom plate 11 has a square shape, and the length of each shim 18 is substantially equal to one side of the bottom plate 11. The shims 18 are not present at the four corners of the case wall 12, but such portions are very small, and the emission of electromagnetic waves from these portions is often negligible. When an electromagnetic shielding material (not shown) bent at a right angle at approximately the same height as the shim 18 is applied to the inner part of the four corners of the wall part 12, electromagnetic waves are emitted from the four corner parts of the wall part 12 to the outside. Can be effectively prevented.

  As described above, the communication device 10 according to the present embodiment positions the shim 18 with the pins 19 of the case 13 and attaches the shims 18 to the wall portion 12, and then positions the pins 19 so as to be inserted into the positioning holes 21. If the cover 16 is pressed against the case 13, these strong connections are easily completed. In addition, since the case 13 and the cover 16 are coupled by the shim 18 having a spring property, even when the cover 16 is removed from the case 13, the same shim 18 can be reused to perform the coupling.

<Modification of the invention>
8 to 14 show a communication device according to a modification of the present invention. Among these, FIG. 8 which shows the external appearance before the coupling of communication devices corresponds to FIG. 1, and FIG. 9 which shows a state where each part is disassembled corresponds to FIG. FIG. 10 showing the positional relationship of the shim with respect to the cover and the case, and FIG. 11 in which a portion surrounded by a broken line 24A as an essential part thereof is enlarged, corresponds to FIGS. 3 and 4, and FIG. And FIG. 13 corresponds to FIG. 5 and FIG. FIG. 14 showing changes in the shape of the shim when the cover is attached to the case corresponds to FIG. Therefore, in the modification shown in FIGS. 8 to 14, the same parts as those in the embodiment shown in FIGS. 1 to 7 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  Also in the communication device 10A of this modified example, as shown in FIG. 8 or FIG. 10, the shim 41 is positioned and attached to the wall portion 12 of the case 13 with the pins 19, and the cover 16 is pressed against the case 13 from above. Are supposed to be combined. The shims 41 extend vertically upward as shown in FIGS. 11 to 13, and their upper portions are bent in an arc shape toward the outside of the wall portion 12 of the case, and are comb-toothed at intervals in the longitudinal direction. There are seven upward protruding pieces 42 arranged in a shape.

  These upward projecting piece portions 42 are connected to a connecting portion 25 having two through holes 22 as in the previous embodiment. Further, the portion of the connecting portion 25 excluding the portion where the through hole 22 is arranged in the longitudinal direction thereof is an isosceles triangle with the upper end portion slightly opened as a cross-sectional shape with the lower portion of the upward protruding piece portion 42. The folded portion 43 is formed by folding. A portion of the folded portion 43 that faces the upward protruding piece 42 is cut in the length direction of the connecting portion 25 with a slight distance from the upward protruding piece 42. On the other hand, at the portion of the folded portion 43 that does not face the upward protruding piece portion 42, the folded portion 43 is further folded by a predetermined length so as to form a plane parallel to the lower portion of the upward protruding piece portion 42. A downward projecting piece 45 is formed. The lower end portion of the downward projecting piece 45 is also bent in an arc shape toward the outside of the wall portion 12 of the case.

  Therefore, as shown in FIG. 8, in the state where each shim 41 is temporarily fixed to the wall portion 12 of the case, the upper protruding portion 42 and the lower protruding portion 45 are both parallel to the wall portion 12, and It is in a state of projecting outward from this. The lower protruding piece 45 is slightly outwardly protruded from the upper protruding piece 42.

  The manner in which the cover 16 is attached to the case 13 with the communication device 10A of this modification will be described with reference to FIG. FIG. 5A shows an initial state in which a shim 41 is attached by a pin not shown in the figure between the upper end portion of the case wall portion 12 and the lower end portion of the cover wall portion 15. In this state, the connecting portion 25 of the shim is disposed so as to contact the upper end portion of the wall portion 12 of the case, and the folded portion 43 is not yet in contact with the lower end portion of the wall portion 15 of the cover.

  FIG. 5B shows a case where the lower end portion of the cover wall portion 15 is brought into contact with the shim folding portion 43, and the lower end portion of the wall portion 15 is brought close to the upper end portion of the case wall portion 12 by a predetermined distance in this state. It represents. Since the shim 41 is made of a material rich in elasticity, as the lower end of the wall 15 approaches the upper end of the wall 12, the angle formed by the shim connecting portion 25 and the folded portion 43 becomes narrower. At the same time, the tip end portion 42A indicated by the arrow in the upward projecting piece portion 42 arranged at a predetermined angle with the connecting portion 25 approaches the wall portion 15 and is arranged at a predetermined angle with the folded portion 43. The tip 45 </ b> A indicated by the arrow in the downward protruding piece 45 approaches the wall 12.

  FIG. 4C shows a state in which the lower end portion of the wall portion 15 of the cover is further pressed against the upper end portion side of the wall portion 12. As the lower end portion of the wall portion 15 is lowered, the angle formed by the connecting portion 25 and the folded portion 43 is further reduced. As a result, the tip end portion 42A of the upward projecting piece portion arranged at a predetermined angle with the shim connecting portion 25 contacts the wall portion 15, and the tip portion 45A also contacts the wall portion 12 in the same manner. . Finally, as shown in FIG. 4D, both the upper protruding piece 42 and the lower protruding piece 45 are bent and the angle formed between the connecting portion 25 and the folded portion 43 becomes zero. At this time, due to the spring property of the shim 18, the downward protruding piece 45 gives a force to lift the case wall 12 upward, and the upward protruding piece 42 presses the wall 15 of the cover in pressure contact therewith. Gives downward force. As a result, the upper end surface of the wall portion 12 of the case and the lower end surface of the wall portion 15 of the cover are always in pressure contact with each other via the folded portion of the shim connecting portion 25 and the folded portion 43.

  The shim 18 is thin, and is in pressure contact with the wall portion 15 of the cover and the wall portion 12 of the case without a gap at the place where the connecting portion 25 and the folded portion 43 are folded. Moreover, the front end portions 42A and 45A of the shim press the wall portions 15 and 12 from the outside. Therefore, not only the electrical contact between the case 13 and the cover 16 is kept good, but also the electromagnetic shielding function can be exhibited well.

  In the embodiment and the modification described above, the bottom plate 11 having a square shape is used. However, it may be a rectangle or a polygon having a pentagon or more or a triangle. In short, the shims 18 and 41 may have a length corresponding to each side. Further, in the embodiment, the shim 18 in which the Z-shaped portion 17 is linearly connected is prepared, but the connecting portion 25 is also arranged at the corner portion of the wall portion 12 by forming a shape in which two or more sides are connected. It becomes possible.

  In the embodiment and the modification, the entire case 13 and cover 16 are made of metal. However, it is natural that a case or cover whose entire surface is covered with a conductor or deposited may be used.
