  However, when both sides of the case lid are fitted from the front to the outer surfaces on both sides of the case body, the case lid can be fitted straight and smoothly into the case body, and the assemblability is improved. There has been a demand that moisture and the like can be prevented from entering the case body from the gap between the inner surface of both sides of the case lid and the outer surface of the case body.

  The present invention has been made to meet the above-described demands, and an object of the present invention is to provide a storage case for an electrical device that is devised so that it can be easily assembled and can prevent moisture and the like from entering. Is.

  In order to solve the above-described problems, the present invention projects a rectangular box-like case body that can accommodate an electrical device from the front opening and a lid portion that can close the front opening of the case body to the rear. A case lid having both sides that can be fitted to the outer surfaces on both sides of the case body from the front, and dovetail grooves extending in the front-rear direction are formed on both outer surfaces of the case body. On the inner surfaces of both side portions, ants that can be engaged with the dovetail grooves are formed, and on the rear end portions of both side portions, locking claws that can be locked on the rear surface of the case body are formed. The dovetail of the body has a wide left-right gap on the inlet side and a narrow left-right gap on the outlet side, and the dovetail of the case lid can be bent in the left-right direction on the rear end side. A storage case for electrical equipment is provided.

  According to a second aspect of the present invention, the electrical device is a lighting device such as an LED, the case body is made of a transparent synthetic resin, and the case lid is made of an opaque synthetic resin. It can be set as the structure which illuminates at least one of the directions.

  According to the present invention, when the both sides of the case lid are fitted from the front to both outer surfaces of the case body, the case lid is engaged with the dovetail groove of the case body. So that when the case lid is completely fitted into the case body, the case lid is locked to the case body by locking the case lid's locking claw to the rear surface of the case body. Become.

  And when the both sides of the case lid are fitted to the outer surfaces on both sides of the case body from the front, the dovetail groove of the case body has a wide gap in the left-right direction (depth direction of the dovetail groove) on the inlet side. It becomes easy to engage the rear end portion (fitting start end portion) of the dovetail with the inlet end portion of the dovetail groove.

  In addition, the rear end portions of the both sides of the case lid are slightly pushed outward by the locking claws riding on the outer surfaces of both sides of the case body, and accordingly, the rear end portion side of the ants is also displaced outward. However, since the gap in the left-right direction on the inlet side of the dovetail groove is wide, the rear end portion side of the dovetail does not come into strong contact with the dovetail groove, and the fitting can be performed smoothly.

  In addition, the gap on the outlet side of the dovetail groove is narrow (regular gap), but the dovetail can bend on the rear end side, so it does not come into strong contact with the dovetail and the fitting is the last. Can be done smoothly. In this way, the assemblability when the case lid is assembled to the case body is improved.

  In addition, when the case lid is completely fitted into the case body, and the case lid is locked to the case body by locking the case lid with the claw of the case body, the rear end side of the ant Because the inner surface of both sides of the case lid is pressed against the outer surface of the case body by the bending force of the case, there is no gap between the inner and outer surfaces, and moisture etc. can be prevented from entering the case body through this gap become able to.

  According to claim 2, if a lighting fixture such as an LED (light emitting diode) is housed inside the case body, for example, when installed in a bathroom, the case body illuminates with at least one of light in the vertical direction through the light. So that you can expect a healing effect.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 8 (a) and 8 (b), a storage case 2 of an LED (light emitting diode) unit 5 as a lighting fixture which is an electric device is formed in a horizontally long rectangular shape and is fixed to the wall surface 1 of the bathroom in a horizontal direction. Will come to be.

  As shown in FIG. 8 (b), the storage case 2 can close the front rectangular opening 3a that can accommodate the LED unit 5 from the front opening 3a, and the front opening 3a of the case 3. A case lid 4 having both side portions 4b projecting rearward from both sides of the lid portion 4a and capable of being fitted to both side outer surfaces 3b of the case body 3 from the front side is provided.

  The case body 3 is made of a transparent synthetic resin, and the case lid 4 is made of an opaque (for example, milky white) synthetic resin. The LED unit 5 passes through the case body 3 and illuminates with faint light in the vertical direction [FIG. a) (see the dash-dot line arrow)], a healing effect and the like can be expected.

  As shown in FIGS. 1, 3 to 5, a square box-shaped LED unit 5 in which LEDs are stored in a watertight state is disposed at a substantially central position in the length direction inside the case body 3. As shown in FIG. 3, the unit 5 is fixed to the bottom 3c of the case body 3 with two sets of screws 6a and nuts 6b.

  A cylindrical portion 3d for drawing out the wires of the LED unit 5 to the outside is formed at a substantially central position in the length direction of the bottom portion 3c of the case body 3, and the screws 6a are provided on both sides of the cylindrical portion 3d. A screw hole 3e for inserting the case body 3 is formed, and screws for fixing the case body 3 to the wall surface 1 through the packing 7 (see FIG. 3) are inserted on both sides of the screw hole 3e. A hole 3f is formed.

  On both side outer surfaces 3b of the case body 3, dovetail grooves (concave ridges having a substantially inverted T-shaped cross section) 3g extending in the front-rear direction at substantially intermediate positions in the vertical direction are formed.

  As shown in FIG. 5 (a), the dovetail groove 3g has a gradient such that the lateral gap (groove depth) t1 on the inlet side is wide and the lateral gap (groove depth) t2 on the outlet side is narrow. The shape is set (t1> t2). The left-right gap t2 on the outlet side is a normal gap, and the left-right gap t1 on the inlet side is wider than the normal gap.

  On the rear surface 3h of the bottom portion 3c of the case body 3, a rear surface recess 3i for locking a locking claw 4f to be described later is formed at a corner portion with both side outer surfaces 3b.

  Small semicircular drain holes 3j are formed on both side portions of the front edge at the lower position of the front opening 3a of the case body 3.

  As shown in FIGS. 1, 3, 6, and 7, the inner surface of both side portions 4 b of the case lid 4 has an ant ((substantially inverted T) that can be engaged with the dovetail grooves 3 g of the both outer surface 3 b of the case body 3. 4c is formed.

  As shown in FIGS. 6A and 6C, this ant 4c has a slit 4e formed in a substantially inverted T-shaped vertical bar portion on the rear end 4d side so that the rear end 4d side is It can be bent in the left-right direction (the depth direction of the dovetail groove 3g) [see the arrow in FIG. 6 (c)].

  A plurality of inwardly engaging claws 4 f that can be engaged with the rear surface recess 3 i of the case body 3 are formed at the rear end portions of both side portions 4 b of the case lid 4.

  On the inner surface of the lid portion 4a of the case lid 4, two upper and lower vertical ribs 4g extending in the vertical direction are formed at a substantially central position in the length direction, and extending in the lateral direction at both side positions in the length direction. There are two upper and lower horizontal ribs 4h. One of the upper and lower horizontal ribs 4h faces directly above the drain hole 3j of the case body 3 when the case lid 4 is completely fitted to the case body 3, and extends above the drain hole 3j. It comes to cover.

  If the storage case 2 of the LED unit 5 is configured as described above, the case lid is inserted into the dovetail groove 3g of the case body 3 when the both side portions 4b of the case lid 4 are fitted to the both side outer surfaces 3b of the case body 3 from the front. When the ant 4c of 4 is engaged, the case lid 4 can be fitted straight to the case body 3 by the guide of the ant 4c by the ant groove 3g, and the case lid 4 is completely fitted to the case body 3. In addition, as shown in FIG. 2, the case lid 4 is locked to the case body 3 by the locking claw 4 f of the case lid 4 being locked to the rear surface recess 3 i of the case body 3.

  When the side portions 4b of the case lid 4 are fitted to the outer side surfaces 3b of the case body 3 from the front side, the dovetail groove 3g of the case body 3 has a wide gap t1 in the left-right direction (depth direction of the dovetail groove 3g) on the inlet side. Therefore, it becomes easy to engage the rear end portion (fitting start end portion) 4d of the dovetail 4c of the case lid 4 with the inlet end portion of the dovetail groove 3g.

  Further, the rear end portions 4d of the side portions 4b of the case lid 4 are slightly pushed outward by the locking claws 4f riding on the outer side surfaces 3b of the case body 3, and accordingly the rear end portions of the ants 4c. Although the 4d side is also displaced outward, since the left and right clearance t1 on the inlet side of the dovetail groove 3g is wide, the rear end 4d side of the dovetail 4c does not come into strong contact with the dovetail groove 3g, and fitting can be performed smoothly. It becomes like this.

  Furthermore, although the gap t2 in the left-right direction on the outlet side of the dovetail groove 3g is narrow (regular gap), the dovetail 4c can be bent on the rear end portion 4d side, and thus does not come into strong contact with the dovetail groove 3g. The mating can be performed smoothly until the end.

  In this way, the assemblability when the case lid 4 is assembled to the case body 3 is improved.

  Further, the case lid 4 is completely fitted to the case body 3 and the locking claw 4f of the case lid 4 is locked to the rear surface recess 3i of the case body 3, so that the case lid 4 is locked to the case body 3. Then, since the inner surface of the both side portions 4b of the case lid 4 is pressed against the both outer surface 3b of the case body 3 by the bending force on the rear end portion 4d side of the ant 4c, no gap is formed between the inner and outer surfaces. It is possible to prevent moisture and the like from entering the case body 3 through the passage.

  Since the LED unit 5 stores the LEDs in a watertight state, a strict watertight (waterproof) structure is not necessarily required between the case body 3 and the case lid 4, but moisture is contained in the case body 3. If a large amount enters, the lighting effect will be adversely affected, so it is preferable to have a water-tight (waterproof) structure that does not allow moisture to enter. From this point also, moisture and the like will enter the case body 3 in advance. It is preferable to prevent.

  The LEDs of the LED unit 5 emit light toward the front, and the emitted light is reflected by the inner surface of the case lid 4 and dispersed in the vertical direction, and passes through the upper and lower walls of the case body 3 so that the light is light in the vertical direction. It becomes illuminated with.

  Since the LED of the LED unit 5 has a semi-permanent life, in principle, it is not necessary to replace it. However, when removing the case lid 4 from the case body 3 for maintenance or the like, use a tool to The case 4 can be removed from the case body 3 by pulling the case cover 4 rearward in a state where the locking claw 4 f of the lid 4 is removed from the rear surface recess 3 i of the case body 3.

  In the above-described embodiment, the case body 3 is illuminated in the vertical direction. However, only upward illumination or downward illumination may be used.
