  According to the present invention, the number of parts and the number of assembly steps can be reduced.

The disassembled perspective view which shows the main structures of a portable device. (A) is a perspective view which shows the front side of the case for board | substrate holding, (b) is a perspective view which shows the back side of the case for board | substrate holding. The disassembled perspective view which shows the main structures of the portable device of a comparative example.

Hereinafter, an embodiment of the portable device will be described.
As shown in FIG. 1, a portable device 1 possessed by a user as a vehicle key is capable of wireless communication with a vehicle-mounted device, and a substrate holding case in addition to a substrate 3 on which an antenna 2 serving as a communication medium is mounted. 4, a battery 5, and a battery cover 6 are accommodated in a decorative case 7. A battery cover 6 is detachably attached to the substrate holding case 4 to constitute a battery take-out portion.

  In addition to the antenna 2, a switch 8 to which a vehicle operation (locking / unlocking a door lock, etc.) is assigned, a microcomputer (not shown) for executing communication control, and a terminal (not shown) to which a battery 5 is connected are provided on the board 3. ) Has been implemented.

  The decorative case 7 is composed of a pair of upper and lower cases (an upper case and a lower case). When a button assembled in the upper case (not shown) is pressed, the switch 8 immediately below the button is turned on. A radio signal instructing the operation assigned to the switch 8 is transmitted to the outside through the antenna 2.

  As shown in FIGS. 2A and 2B, the case 4 for holding the substrate has a substrate holding portion 11 that realizes the holding function of the substrate 3 and is formed in a substantially trapezoidal shape with a hard resin. Silicone rubber is insert molded at the required locations.

  And, by the elastic silicone rubber, on the front side of the case 4 for holding the substrate, a substrate protection unit 12 that realizes a function to alleviate the impact on the substrate 3 held by the substrate holding unit 11 is formed. A sheet-like antenna protection unit 13 that realizes the protection function of the antenna 2 mounted on the antenna 3 is formed. Similarly, on the back side of the case 4 for holding the substrate, a ring-shaped waterproof seal portion 14 that realizes the waterproof function of the battery take-out portion is formed. Further, the side portion of the case 4 is fitted with the decorative case 7. At the joint portion, a projecting impact absorbing portion 15 is formed that realizes a function of protecting the components housed in the decorative case 7 from impact.

  The substrate protection unit 12, the antenna protection unit 13, the waterproof seal unit 14, and the impact absorption unit 15 are different from the function of holding the substrate 3 by the substrate holding unit 11 (the original function in the case 4 for holding the substrate). It corresponds to the other functional part that realizes.

Next, the operation of the portable device 1 will be described.
As shown in FIG. 3, a portable device 20 of a comparative example different from the portable device 1 of this example includes a substrate 22 on which an antenna 21 is mounted, an antenna protection sheet 23 made of a soft material, and a substrate holding case. 24, a battery 25, and a battery cover 26 are accommodated in a decorative case 27. The battery cover 26 is insert-molded with silicone rubber to form a waterproof seal shape 28. In this case, the holding function of the substrate 22 is performed by the case 24 for holding the substrate, the protection function of the antenna 21 is performed by the antenna protection sheet 23, and the waterproof function of the battery take-out portion is performed by the cover 26 for the battery. Three functions will be implemented with three parts, and the number of parts and assembly man-hours will increase.

  On the other hand, the portable device 1 of this example implements the protection function of the antenna 2 and the waterproof function of the battery take-out part in the case 4 for holding the board in addition to the holding function of the board 3, and the shock to the board 3. Since the function of mitigating and the function of protecting the components housed in the decorative case 7 from impact are also implemented in the case 4 for holding the substrate, the number of components and the number of assembling steps can be reduced.

As described above, according to the present embodiment, the following operational effects can be achieved.
(1) Originally, a dedicated part that realizes the function of the other function part is abolished by adding another function part such as the antenna protection part 13 by insert molding to the case 4 for holding the board having the substrate holding part 11 it can. Therefore, the number of parts and assembly man-hours can be reduced.

(2) The dedicated component (antenna protection sheet 23) for realizing the protection function of the antenna 2 can be eliminated.
(3) Dedicated parts that realize the waterproof function of the battery take-out part can be eliminated. Alternatively, when the portable device 20 is originally replaced with the battery cover 26 in which the waterproof seal shape 28 is formed, the waterproof seal shape 28 can be eliminated from the battery cover 26.

(4) In addition to protecting the substrate 3 held by the substrate holding unit 11 from impact, a dedicated component for realizing such a function can be eliminated.
(5) In addition to being able to protect the parts housed in the decorative case 7 from impact, dedicated parts for realizing such functions can be eliminated.

In addition, the said embodiment can also be changed and actualized as follows.
In the portable device 1 of the above-described embodiment, the battery cover 6 is different from the battery cover 26 because the waterproof seal portion 14 is formed by insert molding into the case 4 for holding the substrate. The waterproof seal shape 28 is not formed. In view of this, a cover portion corresponding to the battery cover 6 may be integrated with the decorating case 7. That is, a decorative case having a cover part is manufactured by monochromatic molding with a decorative resin, and is replaced with the battery cover 6 and the decorative case 7. According to this configuration, the number of parts and assembly man-hours can be reduced by eliminating the battery cover 6.

The material used for insert molding into the case 4 for holding the substrate is not limited to silicone rubber. Any type of elastomer may be used.
-As insert molding to case 4 for substrate maintenance, multicolor molding which combines two or more materials may be used.

  -It is not limited to the structure by which all of the board | substrate protection part 12, the antenna protection part 13, the waterproof seal part 14, and the impact absorption part 15 are formed by insert molding to the case 4 for board | substrate holding. At least one or other functional unit different from them may be formed. In addition, when a plurality of other functional parts are formed, each of the other functional parts may be formed of different materials.

The materials used for the case 4 for holding the substrate, the cover 6 for the battery, and the case 7 for decorating can be appropriately changed in consideration of affinity and the like.
-According to the above embodiment, the present invention may be applied to a portable device 1 capable of unidirectional communication with the portable device 1 as a transmission side, or instead of or in addition to the unidirectional communication. The present invention may be applied to a portable device capable of bidirectional communication between them. The portable device used as a building key (electronic key) is not limited to the portable device used as a vehicle key.
