By the way, a board component such as an IC card (card with a built-in memory IC) may be mounted on the electrical board stored inside the electrical board storage case. Therefore, we want to make it easy to remove the lid of the electrical board storage case installed indoors during maintenance and inspection. On the other hand, an electrical board storage case installed outdoors often requires a structure to prevent theft of board parts in addition to removing the lid for maintenance and inspection.

However, in the above-mentioned prior art, the portion fixing the lid body to the case body can be easily removed, and when the lid body is installed outdoors, the lid body may be opened and the board parts may be stolen. As a countermeasure for this, for example, it is conceivable to fix the lid body to the case body with screws. However, in the case of an electrical board storage case installed outdoors, the design is also important, so the anti-theft screws may be exposed on the outer surface and the design may be deteriorated.

Therefore, in the present invention, the lid body can be easily opened by providing a structure for restricting the opening operation of the lid body between the case body and the lid body so that the design of the electrical board storage case is not deteriorated. The purpose is to provide an electrical board storage case that cannot be used.

In order to achieve the above object, the present invention is an electrical board storage case including a case body having an open front surface and accommodating an electrical board inside, and a lid body for closing the front surface of the case body. The case body includes a guide portion for sliding the lid body in parallel with the front surface, and a locking portion for locking the lid body slid along the guide portion. A sliding portion that slides along the guide portion and an engaging portion that engages with the locking portion with the front surface of the case body closed are provided, and further, between the inner surface of the lid and the case body. The lid is provided with a regulating unit that regulates the sliding movement of the lid in the opening direction. The "electrical board" in this specification and documents within the scope of claims includes a board on which electronic components are fixed, a board on which an IC card containing a memory IC or the like is mounted, and the like.

With this configuration, the sliding portion of the lid body is slid along the guide portion of the case body, and the engaging portion of the lid body is engaged with the locking portion of the case body, so that the opening of the case body is closed by the lid body. be able to. Then, since the sliding of the lid in the opening direction can be restricted by the regulating portion at a position different from the engaging portion in which the lid is engaged with the case body, the lid can be attached to the case body. It can be prevented from easily sliding. Moreover, since the regulating portion is provided between the inner surface of the lid and the case body, the regulating portion is not exposed on the outer surface, and the design of the electrical board storage case is not deteriorated. Therefore, the electrical board storage case can be provided with an anti-theft structure in consideration of design.

Further, the regulating portion is provided at a position corresponding to a recess provided in at least one of the case body and the lid body and the recessed portion in the other of the case body and the lid body with the lid body closed. It may be composed of a convex portion formed therein. With this configuration, the opening of the case body is closed by the lid, so that the concave portion and the convex portion are fitted to regulate the sliding movement of the lid in the opening direction. Therefore, a configuration that prevents the lid from being easily removed from the case body can be realized with a simple structure.

Further, the convex portion may be configured to be removable. With this configuration, the restriction on the sliding movement of the lid in the opening direction by the regulating portion can be released by removing the portion that restricts the sliding of the lid of the regulating portion in the opening direction. As a result, when it is not necessary to regulate the slide of the lid body, the slide of the lid body can be easily prevented from being regulated. Therefore, the lid of the electrical board storage case that does not require an anti-theft structure can be easily removed.

Further, the convex portion may be configured so that the height of projecting toward the concave portion can be adjusted. With this configuration, by adjusting the height of the convex portion, the fitting height between the convex portion and the concave portion of the regulating portion changes, and the strength that regulates the sliding movement of the lid can be adjusted. it can.

Further, the convex portion may be made of a screw material having a head. With this configuration, it is possible to easily provide a portion of the regulating portion that restricts the sliding movement of the lid in the opening direction.

Further, the screw material may also serve as a fixing screw material for fixing the case body to the mounting surface. With this configuration, the fixing screw material that fixes the case body to the mounting surface can have both the function of fixing the case body and the function of restricting the sliding movement of the lid in the opening direction.

According to the present invention, with the lid attached to the case body, the lid can be restricted from sliding and moving from the case body in the opening direction by the regulating portion, so that the lid cannot be easily removed. It will be possible. Moreover, since the regulating portion is provided between the case body and the inner surface of the lid, the design of the electrical board storage case does not deteriorate.

Further, the lid 20 is a state in which the slide portion 21 is moved downward along the guide portion 11 of the case main body 10 and the engaging portion 22 is locked to the locking portion 12 of the case main body 10. The engaging step portion 24 provided on the upper part of the lid 20 is locked to the locking step portion 14 provided on the upper part. As a result, the lid 20 is maintained in a state of being locked and attached to the case body 10 by the upper engaging step portion 24 and the lower sliding portion 21 and the engaging portion 22.

(Structure of regulatory department)
FIG. 7A is a partial cross-sectional view showing before regulation of the regulation unit 30 provided between the case body 10 and the lid 20. FIG. 7B is a partial cross-sectional view showing a state in which the sliding movement of the lid 20 is restricted by the restricting portion 30 shown in FIG. 7A.

The state shown in FIG. 7A shows the regulation unit 30 in the state shown in FIG. 5A. In the case body 10, the screw material 33 is screwed into the hollow hole 18a provided in the screw seat 18. Then, the slide portion 21 of the lid 20 is slid downward along the guide portion 11 of the case body 10. When the lid 20 is slid downward, the lower end of the lid 20 comes into contact with the head 34 of the screw material 33. Since the relief portion 25 is provided on the inner surface 23 of the lid body 20, after the lid body 20 comes into contact with the head 34 of the screw material 33, the central portion is gradually elastically deformed forward by the head 34. It is slid downward while being done.

The state shown in FIG. 7B shows the regulation unit 30 in the state shown in FIG. 5B. The lid 20 is slid downward and stops at a position where the engaging portion 22 is locked to the locking portion 12 of the case body 10. In this state, the recess 31 formed on the inner surface 23 of the lid 20 reaches the position of the head 34, and the head 34 fits into the recess 31. As a result, in the lid body 20, the upper engaging step portion 24 is locked to the locking step portion 14 of the case body 10, and the lower engaging portion 22 is locked to the locking portion 12 of the case body 10. At the same time, the recess 31 of the lid 20 is locked to the head 34 of the screw material 33 attached to the case body 10 at a distant position. Therefore, the lid 20 is regulated so that it cannot easily slide in the opening direction.

Further, as the screw material 33 having the head portion 34 constituting the convex portion 32, as shown by the alternate long and short dash line, a long fixing screw material 35 for fixing the case body 10 to the mounting surface 50 such as a wall surface can be used. .. By using the fixing screw material 35, the fixing screw material 35 for fixing the case body 10 to the wall surface or the like can also function as the convex portion 32 of the regulating portion 30.

According to the electrical board storage case 1 as described above, by attaching the lid 20 to the case body 10, the recess 31 is fitted into the head 34 of the screw material 33, and the lid 20 can be easily removed from the case body 10. You can avoid it. That is, in order to remove the lid 20 from the case body 10, it is necessary to elastically deform the central portion of the lid 20 so that the portion provided with the recess 31 is detached from the head 34 and then slide the lid 20. It can be prevented from being easily removed. Therefore, in the electrical board storage case 1 mounted outdoors or the like, the lid 20 can be made difficult to remove in order to prevent theft.

Further, since the structure for making the lid 20 difficult to remove is not exposed on the outer surface, the design of the electrical board storage case 1 does not deteriorate, so that the anti-theft structure can be made in consideration of the design.

Further, in the case of the electrical board storage case 1 that does not require anti-theft measures (for example, indoor installation, when the end user removes the lid 20), the lid is not attached to the case body 10 by attaching the screw material 33. The structure can be made so that the body 20 can be easily removed.

(Modified example of regulatory section)
FIG. 8 is a partial cross-sectional view showing a second example of the regulation unit 30. FIG. 9 is a partial cross-sectional view showing a third example of the regulation unit 30. In each of the figures, the same configurations as those in the above-described embodiment will be described with the same reference numerals. As shown in FIG. 8, as the regulating portion 30, for example, by lowering the height of the screw seat 18, the screwing amount of the screw material 33 can be adjusted. In this way, the amount of protrusion of the head 34 can be adjusted by the amount of screwing of the screw material 33. By adjusting the amount of protrusion of the head 34, the amount of fitting with the recess 31 of the lid 20 can be adjusted. Therefore, the magnitude of the sliding force for removing the lid 20 from the case body 10 can be adjusted. In this way, the force for removing the lid 20 can be easily adjusted according to the electrical board storage case 1.

In this example, the head 34 of the screw material 33 is the convex portion 32 of the regulating portion 30, and the amount of protrusion of the head 34 can be adjusted. However, the adjustable convex portion 32 is the head of the screw material 33. It is not limited to the part 34.

As shown in FIG. 9, the regulating portion 30 may provide a screw seat 27 on the inner surface 23 of the lid 20 to fix the screw material 33, and may provide a recess 31 in the case body 10. Even in this way, by attaching the lid 20 to the case body 10, the head 34 (convex portion 32) of the screw material 33 of the lid 20 is fitted into the recess 31 of the case body 10, and the lid 20 is easy to use. It can be prevented from being removed. The head 34 of the screw material 33 serving as the concave portion 31 and the convex portion 32 constituting the regulating portion 30 may be provided with either one of the lid 20 and the case body 10 and the other one. Good.
