1 and 2 show a state in which electronic components are stored in a mobile phone as a configuration of an embodiment of an electronic apparatus to which the present invention is applied, and FIG. 3 shows the mobile phone and the inner surface of a lid side by side. Yes, 1 is a housing, 2 is a battery, 3 is a battery lid (electronic component), 4 is packing, 5 is a belt, 6 is a belt cover, 7 is a lock knob (operation unit), 8 is a nut, 9 is packing, 10 Is a screw.

  As shown in the figure, a housing part 11 for housing a battery 2 as an electronic component is formed on the back surface of the housing 1, and the battery 2 is housed in the housing part 11 through the opening 12. A battery lid 3 that can be sealed for waterproofing is detachably attached to the opening 12 of the storage portion 11. A packing groove 13 surrounding the four sides is formed around the storage portion 11, and a fitting groove 14 surrounding the outer side is formed. The packing 4 is fitted in the packing groove 13, and the belt 5 and the belt cover 6 thereon are assembled in the fitting groove 14.

  As shown in FIG. 3, a waterproof first rib 31 surrounding the four sides is integrally formed on the inner surface of the battery lid 3, and a fitting second rib 32 surrounding the outer side thereof is provided. Are integrally formed. The first rib 31 corresponds to the packing groove 13 of the housing 1. A pair of protrusions 33 are formed along the four sides of the battery lid 3 on the outer periphery of the second rib 32, and wide protrusions 34 are formed along the four corners.

  The belt 5 is made of a hard elastomer, and three teeth 51 are formed on the center outer periphery corresponding to the upper side of the fitting groove 14, and a set of three protrusions 53 are formed on the inner periphery along the four sides. ing. The interval between the protrusions 53 corresponds to the protrusions 33 of the second rib 32 of the battery lid 3. Further, a belt cover 6 is provided on the belt 5 so as to prevent the belt 5 from coming off from the fitting groove 14.

  The belt cover 6 is prevented from coming off by inserting a pair of locking claws 61 formed on the left and right outer peripheries corresponding to the upper and lower sides of the fitting groove 14 into the outer peripheries of the upper and lower sides of the fitting groove 14, respectively. The belt cover 6 is integrally formed with a protruding piece 62 that covers the periphery of the lower half of the lock knob 7 on the center outer periphery corresponding to the upper side of the fitting groove 14.

  As shown in FIG. 4, the lock knob 7 as an operation unit is located in the knob through hole 37 of the battery lid 3, and is waterproofed with a nut 8, a packing 9, and a screw 10 against the back surface of the housing 1. It is assembled so that it can be rotated. Four teeth 71 are integrally formed in the lower part of the lock knob 7 over substantially a half circumference. The interval between the teeth 71 corresponds to the teeth 51 on the outer periphery of the belt 5. An operation groove 72 is formed in the head of the lock knob 7 for rotating the tool by applying a tool or a coin.

  5 is a cross-sectional view showing the relationship with the battery lid 3 along the arrow BB line in FIG. 1, and FIG. 6 is an enlarged view of an arrow C portion in FIG.

  As shown in the figure, in a state in which the battery 2 is stored in the storage portion 11 of the housing 1 and the battery cover 3 is mounted, the packing 4 in the packing groove 13 around the storage portion 11 is attached to the battery cover 3. It is waterproofed by being pressed by the first rib 31. Then, in the fitting groove 14 around the packing groove 13, the protrusion on the inner periphery of the belt 5 secured by the belt cover 6 on the protrusion 33 and the wide protrusion 34 on the outer periphery of the second rib 32 around the first rib 31. By overlapping 53, the battery lid 3 is held in a state where the entire periphery is fitted.

  As described above, the second rib 32 formed around the first rib 31 serving as the waterproof portion of the battery lid 3 and having the protrusion 33 and the wide protrusion 34 on the outer periphery, and the packing serving as the waterproof portion of the opening 12 of the housing 1. In the fitting groove 14 around the groove 13, the belt 5 having a protrusion 53 that overlaps with the protrusion 33 and the wide protrusion 34 of the second lid 32 of the battery cover 3 and can be fixed to each other, and the belt 5 is moved. A mechanism for applying a fitting force to the battery lid 3 is constituted by the lock knob 7.

  Next, FIG. 7 illustrates the operation of moving the belt 5. When the lock knob 7 is rotated as indicated by an arrow, the belt 5 that meshes with the teeth 71 of the lock knob 7 with the teeth 51 as indicated by the arrow. 14 moves along the outer periphery.

  FIG. 8 shows a state in which the battery lid 3 is closed and the first rib 31 and the second rib 32 are inserted, and FIG. 9 is an enlarged view of an arrow D portion thereof.

  When closing the battery cover 3, first, as shown in the figure, in the fitting groove 14 of the housing 1, between the protrusion 53 on the inner periphery of the belt 5, the protrusion 33 on the outer periphery of the second rib 32 of the battery cover 3 and The wide protrusion 34 enters. Then, by rotating the lock knob 7, the belt 5 meshed with the teeth 71 of the lock knob 7 by the teeth 51 is moved along the outer periphery in the fitting groove 14.

  FIG. 10 shows a state in which the lock knob 7 is rotated, and FIG. 11 is an enlarged view of the arrow E portion.

  When the belt 5 is moved by the rotation operation of the lock knob 7, the protrusions 53 on the inner periphery of the belt 5 start to overlap the protrusions 33 and the wide protrusions 34 on the outer periphery of the second rib 32 of the battery cover 3 as shown in the figure.

  FIG. 12 shows a state in which the lock knob 7 is further rotated, and FIG. 13 is an enlarged view of the arrow F portion.

  Further, when the belt 5 is moved by rotating the lock knob 7, as shown in the drawing, the protrusion 53 on the inner periphery of the belt 5 is completely formed on the protrusion 33 and the wide protrusion 34 on the outer periphery of the second rib 32 of the battery cover 3. And the battery cover 3 is hermetically sealed over the entire periphery.

  In addition, when opening the battery cover 3, the lock knob 7 is rotated in the direction opposite to the arrow direction.

  As described above, according to the mobile phone of the embodiment, in the fitting groove 14 around the packing groove 13 of the housing 1, the protrusion 33 and the wide protrusion 34 on the outer periphery of the second rib 32 around the first rib 31 of the battery cover 3. Above, the protrusion 53 on the inner periphery of the belt 5 that is prevented from coming off by the belt cover 6 is overlapped, and the battery cover 3 is held in a state where the entire periphery is fitted, so that floating when the battery cover 3 is closed is prevented. can do.

(Modification)
FIG. 14 shows a modification of the operation portion. As shown in the drawing, a slide integrally formed on the outer periphery of the belt 5 in a through hole 15 formed by opening one side portion from the fitting groove 14 of the housing 1. A knob 55 is arranged and protrudes to the outside. A seal rubber 16 is provided on the opening side of the through-hole 15 so as to be waterproof while allowing the slide knob 55 to slide.

  As described above, the belt 5 may be moved by the slide operation of the slide knob 55.
