As shown in these drawings, the adapter 2 is lowered and the concave portion 24 of the adapter 2 is put on the connector housing 60 of the spring connector 6, so that the first electrode surface 31 of the conductor portion 30 of the adapter 2 and the spring connector 6 are covered. The terminal pins 65 of the terminal pins 65 are in contact with each other and are electrically connected to each other. The terminal pin 65 is pushed by the first electrode surface 31 and contracts, and the tip end portion 66 retracts. Of the four terminal pins 65, two of the large diameters are for power supply and two of the small diameters are for signals. That is, power supply and signal transmission / reception can be performed between the portable device 1 and the portable device holder 5. Although not shown, a cable is electrically connected to the base end surface of each terminal pin 65 by soldering, for example, and the terminal pin 65 is electrically connected to a substrate (not shown) by this cable. The elastic ring 7 is pressed against the adapter housing 20 over the entire circumference. Thus, it is possible to prevent water from entering through the gap between the adapter housing 20 and the connector housing 60 (a watertight space can be formed between the adapter housing 20 and the connector housing 60).

  FIG. 16A is a front perspective view of a state in which the portable device holder 5 holding the portable device 1 is fixed to the stand 8. FIG. 16B is a rear perspective view of the same. FIG. 17A is a front perspective view of the stand 8 and the portable device holder 5 separated from each other. FIG. 17B is a rear perspective view of the same. When the button 81 of the stand 8 is pressed and the pair of claws 83 are brought close together, the claw 83 is inserted into the engagement hole 84 on the back surface of the portable device holder 5 and then the button 81 is released. The portable device holder 5 can be fixed to the stand 8. Further, the swing angle of the portable device holder 5 can be adjusted by loosening the screw 82 of the stand 8. The stand 8 is for in-vehicle use in the illustrated example, and the bottom surface has adhesiveness, and is bonded and fixed to, for example, the upper surface of a dashboard of a car. Since the structure of the stand 8 is well known, further detailed description is omitted.

  According to the present embodiment, the following effects can be achieved.

(1) Since each conductor part 30 has the 1st electrode surface 31 and the 2nd electrode surface 32, even if the specification of the spring connector 6 of the holder 5 for portable devices differs, it can respond flexibly. For example, in the case of the terminal pin 72 projecting obliquely as shown by a two-dot chain line in FIG. 18, it is difficult to make contact with the first electrode surface 31, but in the present embodiment, the second electrode surface 32 Contact can be suitably achieved.

(2) Conventionally, the waterproofing of the holder for the portable device has not been particularly taken into consideration, but in this embodiment, the connector insertion hole 58 is watertightly sealed by providing the elastic ring 7, and the adapter housing 20 and the connector housing are further sealed. Since watertight sealing is also performed with respect to 60 (watertight space is formed), waterproofness is enhanced. In particular, in the case of in-vehicle use, drinks and the like are often spilled in a vibrating vehicle, and thus high waterproofness is required. However, this embodiment is suitable for such use.

(3) Since the rib 62 is provided between the terminal pins 65 protruding from the upper surface of the connector housing 60, even if water enters, a short circuit between the terminal pins 65 is prevented.

(4) Since the adapter 2 can be assembled simply by inserting the conductor portion 30 into the adapter housing 20, the process is simple compared to insert molding.

  The present invention has been described above by taking the embodiment as an example. However, it is understood by those skilled in the art that various modifications can be made to each component and each processing process of the embodiment within the scope of the claims. By the way. Hereinafter, modifications will be described.

  The portable device holder 5 is not limited to the case of being mounted on the vehicle and attached to the stand 8, but may be a desktop holder type as shown in FIG. 19, for example. In this figure, the case where the waterproof function is omitted is shown.

  The mobile device 1 may be a mobile phone other than a smartphone, a mobile communication device, a mobile music player, or the like.

  The number of the conductor portions 30 of the adapter 2 and the terminal pins 65 of the spring connector 6 is arbitrary, and may be appropriately determined according to the application.
