In FIG. 2, a state in which both relay terminals 40a and 40b are arranged in the upper case 31a of the main body holder 31 is illustrated as a bottom view as viewed from the lower side (lower case side). The first guide 33 corresponds to an example of a “first guide” recited in the claims.

  The first guide 33 has a gap between the guide surfaces slightly larger than the wire diameter of the relay terminal 40a in order to smoothly guide the mobile device side end portion 42 and the connecting portion 43 that slide in the sliding direction. It is formed to have a constant interval. At this time, the relay terminal 40a protrudes into the accommodating portion 32 at a part of the portable device side end portion 42, and slides along the auxiliary guide 34 provided on the lower surface of the upper case 31a at the second guide portion 45. To be guided.

  Then, by assembling the lower case 31b to the upper case 31a in which the relay terminal 40a is arranged as described above, the relay terminal 40a is connected to the guide surface 35a of the upper case 31a and the lower case 31b by the first guide portion 44.

Here, in order for the second guide 35 to smoothly guide the second guide portion 45 that slides in the sliding direction, the gap between the guide surface 35a and the guide surface 35b is slightly smaller than the wire diameter of the relay terminal 40a. It is formed so as to have a large and constant interval. The second guide 35 corresponds to an example of a “second guide” recited in the claims.

  In each of the guides 33 to 35 described above, when the attachment 30 is attached to the attachment attachment portion 22 of the apparatus main body 21, both the conduction portions 41 a and 41 b of the charging device side end 41 of the relay terminal 40 a are inserted into the predetermined gap S. It arrange | positions so that the conduction | electrical_connection part 23a of the positive side electric power feeding terminal 23 may be pinched | interposed and contacted (refer FIG. 5 (A), (B)). In addition, in this embodiment, although both the conduction | electrical_connection parts 41a and 41b are comprised so that the conduction | electrical_connection part 23a may contact both, even if it contacts the conduction | electrical_connection part 23a on one side so that the conduction | electrical_connection part 23a may be pinched | interposed. Good.

  And the relay terminal 40b is also comprised similarly to the relay terminal 40a, and, thereby, both the relay terminals 40a and 40b are accommodated so that it can slide independently with respect to the main body holder 31, respectively in a sliding direction. It will be.

  Next, charging of the mobile device 10 by the charging device 20 to which the attachment 30 configured as described above is attached will be described with reference to FIGS. 1 and 6. For convenience, FIG. 6 does not show other members in order to explain the contact state between the relay terminal 40a and the positive power supply terminal 23.

  First, an attachment 30 capable of accommodating the portable device 10 to be charged is prepared, and the attachment 30 is attached to the attachment attachment portion 22 of the apparatus main body 21. As a result, the positive power supply terminal 23 comes into contact with the conductive portions 41a and 41b of the relay terminal 40a slidably accommodated in the main body holder 31 at the conductive portion 23a. Further, the negative power supply terminal 24 comes into contact with both conductive portions 41a and 41b of the relay terminal 40b slidably accommodated in the main body holder 31 at the conductive portion 24a. Thereby, the charging device 20 shown in FIG. 1 is completed.

  At this time, both relay terminals 40a and 40b are pressed to the other side in the sliding direction by the two power feeding terminals 23 and 24, so that the other side in the sliding direction is independently guided in the state guided by the guides 33 to 35. To slide.

  Next, the portable device 10 to be charged is accommodated in the accommodating portion 32 of the charging device 20, so that the positive power receiving terminal 12 and the negative power receiving terminal 13 of the portable device 10 are replaced with the portable devices of the relay terminal 40a and the relay terminal 40b. The side end portions 42 are brought into contact with each other. As a result, the relay terminal 40 a and the relay terminal 40 b are pressed to one side in the sliding direction via the positive power receiving terminal 12 and the negative power receiving terminal 13 by the weight of the mobile device 10, and slide relative to the main body holder 31. Slide in one direction.

  Thus, since the relay terminal 40a slides to one side in the sliding direction, the conduction portion 23a of the positive power supply terminal 23 of the charging device 20 is sandwiched between both conduction portions 41a and 41b of the charging device side end 41. Pressed down while touching. Thereby, during charging, the positive power receiving terminal 12 and the positive power feeding terminal 23 are reliably connected via the relay terminal 40a. Similarly, since the relay terminal 40b slides to one side in the sliding direction, the conductive portion 24a of the negative power supply terminal 24 is in contact with the conductive device 41a and 41b of the charging device side end 41 so as to be sandwiched between them. Press down. Thereby, the negative power receiving terminal 13 and the negative power feeding terminal 24 are reliably connected via the relay terminal 40b.

  At this time, the relay terminals 40a and 40b slide along the guide surfaces of the guides 33 to 35 of the main body holder 31 so that the pressing force from the power receiving terminals 12 and 13 is transmitted to the power feeding terminals 23 and 24 as they are. Since each slides to one side in the moving direction, deformation of both relay terminals 40a and 40b due to the pressing force from both power receiving terminals 12 and 13 is suppressed. Moreover, since both the relay terminals 40a and 40b are guided to the 2nd guide 35 by the 1st guide part 44 orthogonal to the plane containing the portable apparatus side edge part 42 and the connection part 43, both the said relay terminals 40a and 40b Is prevented from tilting in the direction along the guide surface when sliding along the guide surface of the first guide 33 at a part of the portable device side end portion 42 and the connecting portion 43.

  Further, when the negative power receiving terminal 13 is displaced so as to be closer to the relay terminal than the positive power receiving terminal 12 due to manufacturing failure of the mobile device 10, first, the negative power receiving terminal 13 is contacted. When the pressed relay terminal 40b slides on the one side in the sliding direction with respect to the main body holder 31, the negative power receiving terminal 13 and the negative power feeding terminal 24 are connected via the relay terminal 40b.

  Thereafter, when the mobile device 10 further moves downward, the relay terminal 40a that is pressed in contact with the positive power receiving terminal 12 slides to the one side in the sliding direction with respect to the main body holder 31, so that the relay is performed. The positive power receiving terminal 12 and the positive power feeding terminal 23 are connected via the terminal 40a.

  Thus, even when the positive-side power receiving terminal 12 and the negative-side power receiving terminal 13 are displaced from each other due to manufacturing defects of the mobile device 10, the positive-side power receiving terminal 12 and the positive-side power feeding terminal 23 serve as the relay terminal 40 a. And the negative power receiving terminal 13 and the negative power feeding terminal 24 are securely connected via the relay terminal 40b.

  Even when the portable device 10 is accommodated in a state inclined with respect to the accommodating portion 32, both the relay terminals 40a and 40b slide independently of the main body holder 31 as described above. The power receiving terminal 12 and the positive power feeding terminal 23 are securely connected via the relay terminal 40a, and the negative power receiving terminal 13 and the negative power feeding terminal 24 are securely connected via the relay terminal 40b.

  As described above, the attachment 30 according to the present embodiment is a wire rod that is guided to be slidable with respect to the main body holder 31 and the main body holder 31 that constitutes the housing portion 32 for housing the mobile device 10. The relay terminals 40a and 40b are configured. Both relay terminals 40a and 40b are both electrically connected to the positive power supply terminal 23 and the negative power supply terminal 24 that are inserted into the predetermined gap S, respectively, when the attachment 30 is attached to the attachment attachment portion 22 of the apparatus main body 21. It contacts so that it may pinch | interpose in both parts 41a and 41b. Further, when the portable device 10 is accommodated in the accommodating portion 32 of the charging device 20 to which the attachment 30 is attached, both the relay terminals 40a and 40b are in contact with the both power receiving terminals 12 and 13 at the portable device side end portion 42. Then, by being pushed to one side in the sliding direction, the conductive terminals 41a and 41b are slid and pressed to the one side in the sliding direction with the power supply terminals 23 and 24 being sandwiched therebetween.

  Thereby, the attachment 30 is formed so as to constitute the housing portion 32 with respect to the portable device 10 to be charged, and can be attached to the attachment attachment portion 22 of the apparatus main body 21 to form a single unit. By attaching the attachment 30 corresponding to the mobile device 10 to be charged to the device main body 21, the charging device 20 capable of charging the mobile device 10 can be configured.

In particular, since both the relay terminals 40a and 40b of the attachment 30 are made of wire together with both the power supply terminals 23 and 24, durability and the like can be improved as compared with the case where a leaf spring-shaped terminal is adopted. Furthermore, since both the relay terminals 40a and 40b are in contact with both the power feeding terminals 23 and 24 so as to be sandwiched by both of the two conductive portions 41a and 41b, even if the terminals are made of wires. Can be contacted.
Therefore, it is possible to configure the attachment 30 having both the high durability relay terminals 40a and 40b that can smoothly come into contact with the power feeding terminals 23 and 24 formed of the wire.

  In addition, in the attachment 30 according to the present embodiment, both the relay terminals 40a and 40b slide along the first guide 33 at a part of the mobile device side end portion 42 and the connecting portion 43, so that both power receptions are performed during charging. The pressing force from the terminals 12 and 13 is directly transmitted to the corresponding power supply terminals 23 and 24 through the relay terminals 40a and 40b. Thereby, compared with the case where there is no 1st guide 33, the deformation | transformation of both the relay terminals 40a and 40b at the time of charge can be suppressed.

  Further, in the attachment 30 according to the present embodiment, both the relay terminals 40 a and 40 b are provided with a first guide portion 44 orthogonal to the guide surface of the first guide 33, and the main body holder 31 has the first guide portion 44. Is formed along the sliding direction. Thereby, since both the relay terminals 40a and 40b are guided along the second guide 35 by the first guide portion 44, the both relay terminals 40a and 40b slide along the guide surface of the first guide 33. It is prevented from tilting in the direction along the guide surface when moving, and the pressing force from both the power receiving terminals 12 and 13 can be reliably transmitted to the corresponding power feeding terminals 23 and 24 as they are.

  Further, in the attachment 30 according to the present embodiment, the relay terminal is composed of two terminals, and both the relay terminals 40a and 40b are guided so as to be independently slidable with respect to the main body holder 31. Even when both the power receiving terminals 12 and 13 are displaced with respect to the main body holder 31 by being accommodated in a state where the terminal 10 is tilted with respect to the accommodating portion 32, the power receiving corresponding to both the relay terminals 40a and 40b. The terminals 12 and 13 can be reliably connected to each other.

  Further, in the attachment 30 according to the present embodiment, the charging device side end portion 41 is formed in a substantially U shape by curving one wire rod by connecting one end portions of the two conduction portions 41a and 41b. Therefore, the relay terminals 40a and 40b having the two conductive portions 41a and 41b can be easily formed.
