(First embodiment; FIGS. 1 to 4)
The charging device 2 shown in FIGS. 1 to 4 is a device for charging a rechargeable electronic device 4 (see FIG. 2). Here, the electronic device 4 is a reading device for reading an information code such as a two-dimensional code, for example. As shown in FIG. 1, the charging device 2 includes a case 10 and a plurality of charging terminals 40. As shown in FIG. 1, a part of the charging terminal 40 protrudes outside the case 10. As shown in FIG. 3, a substrate 20 is further accommodated inside the case 10. Various electronic components (not shown) including electronic components constituting the charging circuit are attached to the substrate 20. The charging terminal 40 is electrically connected to the electronic component attached to the substrate 20.

  As described above, the case 10 is a case for housing various internal elements (not shown) of the charging device 2 such as the substrate 20 and the charging terminal 40. The case 10 is formed by combining an upper case 10a and a lower case 10b. As shown in FIGS. 1 and 2, the upper case 10 a is provided with a placement portion 11 and a support portion 12. The placement unit 11 is a recess in which the end of the electronic device 4 can be placed. The support portion 12 is a recess that can support the back surface portion of the electronic device 4 whose end portion is placed on the placement portion 11.

  The mounting part 11 is provided with an opening 15. A part of the charging terminal 40 (that is, the contact portion 42 in FIG. 3) is provided so as to protrude into the mounting portion 11 from the opening 15. Thereby, when the end portion of the electronic device 4 is placed on the placement portion 11, a terminal (not shown) exposed at the end portion of the electronic device 4 and the contact portion 42 of the charging terminal 40 come into contact with each other. To do. Thereby, the battery built in the electronic device 4 and the charging circuit provided on the substrate 20 in the case 10 are electrically connected via the terminal of the electronic device 4 and the charging terminal 40.

  Subsequently, the configuration in the case 10 will be described in detail with reference to FIGS. 3 and 4. As described above, the substrate 20 is accommodated in the case 10. Various electronic components including electronic components constituting the charging circuit are attached to the substrate 20. In the present embodiment, the substrate 20 is disposed such that the front surface (that is, the upper surface in FIG. 3) faces the upper side of the case 10 (that is, the upper case 10a side) and the back surface (that is, the lower surface in FIG. 3). Surface) is arranged toward the bottom surface of the case 10 (that is, the lower case 10b side). In other words, in this embodiment, the substrate 20 is disposed along a plane substantially parallel to the bottom surface of the case 10. A substrate opening 22 is opened in the substrate 20. The substrate opening 22 is provided below the contact portion 42 and the lower end portion 44 (described later) of the charging terminal 40 in the substrate 20.

  The charging terminal 40 is formed by processing a metal linear member. On one end side of the charging terminal 40, a connection portion 46 that is electrically connected to the electronic component of the substrate 20 is provided. The connection portion 46 is formed in a coil spring shape, and an end portion is inserted through the substrate 20 and fixed. On the other end side of the charging terminal 40, a contact portion 42 that protrudes from the opening 15 of the upper case 10a into the placement portion 11 (that is, outside the case 10) is provided. As described above, the contact portion 42 can contact the terminal of the electronic device 4 placed on the placement portion 11. In FIG. 4, the charging terminal 40 when the electronic device 4 is placed on the placement unit 11 is indicated by reference numeral 40 a. As indicated by reference numeral 40 a, when the electronic device 4 is placed on the placement portion 11, the contact portion 42 is pushed inward of the case 10 by the contact portion 42 coming into contact with the terminal of the electronic device 4. .

  As shown in FIG. 4, the linear member constituting the charging terminal 40 is bent from the contact portion 42 toward the connection portion 46. By bending the linear member, a lower end portion 44 and a gradient portion 48 are formed between the contact portion 42 and the connection portion 46. The gradient portion 48 is formed so that the height gradually increases from the lower end portion 44, which is the end portion on the contact portion 42 side, toward the connection portion 46 (that is, an upward gradient). In the present embodiment, the height H1 of the lower end portion 44 is always lower than the height H2 of the connection portion 46. Further, as described above, in this embodiment, the contact portion 42 and the lower end portion 44 are formed above the substrate opening 22.

  In addition, partition walls 16 a and 16 b are formed inside the case 10. The partition wall 16a is formed integrally with the inner surface of the upper case 10a, and reaches the inner surface of the lower case 10b through the substrate opening 22. The partition wall 16a partitions the substrate 20 and the specific portion 19 that is the lower portion of the substrate opening 22 in the lower case 10b. The partition wall 16 b is formed integrally with the inner surface of the lower case 10 b and extends to the opening edge of the substrate opening 22. The substrate 20 and the specific portion 19 are partitioned by the partition wall 16b. The specific portion 19 has a plurality of through holes 18 communicating with the outside.

  The configuration of the charging device 2 according to the present embodiment has been described above. As described above, in this embodiment, the charging terminal 40 has the gradient portion 48 between the contact portion 42 and the connection portion 46. Therefore, even if the water adhering to the electronic device 4 placed on the placement part 11 enters the case 10 from the contact part 42 through the charging terminal 40, the charging terminal The water passing through 40 does not travel from the contact portion 42 to the lower end portion 44 and then travels up the gradient portion 48 toward the connecting portion 46. Therefore, the water that has entered the case 10 from the contact portion 42 through the charging terminal 40 does not flow from the lower end portion 44 of the gradient portion 48 to the connection portion 46 and falls down from the lower end portion 44 as it is. The dropped water passes through the substrate opening 22 formed below the lower end portion 44 and reaches the specific portion 19. Further, in this embodiment, the substrate opening 22 is formed below the lower end portion 44, and no electronic component is provided. Therefore, water that has dropped from the lower end 44 does not adhere to the electronic component. Therefore, according to the charging device 2 of the present embodiment, it is possible to suppress the occurrence of a situation where water that has entered the case 10 through the charging terminal 40 adheres to the electronic component attached to the substrate 20.

  In the present embodiment, the case 10 is provided with partition walls 16 a and 16 b that partition the specific portion 19 and the portion where the substrate 20 is disposed. Therefore, the water that has reached the specific portion 19 is also prevented from flowing to the substrate 20 side. It can suppress more effectively that water adheres to the board | substrate 20 and an electronic component.

  In this embodiment, a plurality of through holes 18 are formed in the specific portion 19. Thereby, the water that has reached the specific portion 19 can be discharged out of the case 10.

(Modification 1 of the first embodiment; FIG. 5)
With reference to FIG. 5, one of the modifications of the charging device 2 of 1st Example is demonstrated. In this modification, the shape of the substrate 20 is different from that shown in FIG. In the modification shown in FIG. 5, the substrate 20 is not provided with a substrate opening (see reference numeral 22 in FIG. 3). In this modification, when the charging device 2 is viewed in plan, the lower end portion 44 of the charging terminal 40 is disposed outside the outer peripheral end portion 20 a of the substrate 20. In other words, the lower end portion 44 and the substrate 20 are arranged at positions shifted laterally from each other. Also in this modification, the water falling from the lower end 44 falls on the specific portion 19 without adhering to the substrate 20 and the electronic component.

(Modification 2 of the first embodiment; FIG. 6)
With reference to FIG. 6, another modification of the charging device 2 of the first embodiment will be described. In this modification, the shape of the charging terminal 40 is different from that shown in FIGS. In the modification shown in FIG. 6, the charging terminal 40 has a bent portion 43 formed between the contact portion 42 and the connecting portion 46. In the present modification, the lowest portion of the bent portion 43 is the lower end portion 44, and the highest portion of the bent portion 43 is the upper end portion 45. Between the lower end portion 44 and the upper end portion 45 is a slope portion 48, and the height gradually increases from the lower end portion 44 (that is, the contact portion 42 side) toward the upper end portion 45 (that is, the connection portion 46 side) (that is, the ascending slope). Is formed). In the example of FIG. 6, the height of the upper end portion 45 is higher than the height of the connection portion 46. In another example, the height of the upper end portion 45 and the height of the lower end portion 44 may both be higher than the height of the connection portion 46.

  Also in the case of this modification, as in the first embodiment, the water transmitted through the charging terminal 40 travels down from the contact portion 42 to the lower end portion 44 and then travels up the gradient portion 48 toward the upper end portion 45. I can't. Therefore, in this modification, the height of the upper end portion 45 is higher than the height of the connection portion 46, but the water that has entered the case 10 from the contact portion 42 through the charging terminal 40 is the same as in the first embodiment. Without falling from the lower end portion 44 of the gradient portion 48 to the connection portion 46, it falls downward from the lower end portion 44.

(Second embodiment; FIGS. 7 to 9)
With reference to FIGS. 7-9, the charging device 102 of 2nd Example is demonstrated. The charging device 102 of this embodiment is also a device for charging the rechargeable electronic device 104 (see FIG. 8). As shown in FIG. 7, the charging device 102 includes a case 110 and a plurality of charging terminals 140. Also in this embodiment, a part of the charging terminal 140 protrudes outside the case 110. A substrate 120 is further accommodated inside the case 110. Various electronic components including electronic components constituting the charging circuit are attached to the substrate 120. The charging terminal 140 is electrically connected to the electronic component attached to the substrate 120.

  As described above, also in this embodiment, the case 110 is a case for accommodating various internal elements such as the substrate 120 and the charging terminal 40. As shown in FIGS. 7 and 8, the case 110 is provided with a mounting portion 111. The placement unit 111 is a recess that can support and place the end of the electronic device 104. When the electronic device 104 is supported and placed on the placement unit 111, the electronic device 104 is held by the placement unit 111. After the electronic device 104 is held by the placement unit 111, the electronic device 104 is positioned while being held by the placement unit 111 unless the user removes the electronic device 104 from the placement unit 111.

  The mounting portion 111 is provided with an opening 115. A part of the charging terminal 140 (that is, the contact portion 142 in FIG. 9) is provided so as to protrude into the placement portion 111 from the opening 115. As a result, when the end portion of the electronic device 104 is held by the mounting portion 111, the terminal exposed at the end portion of the electronic device 4 and the contact portion 142 of the charging terminal 140 come into contact with each other. Thus, the battery built in the electronic device 104 and the charging circuit provided on the substrate 120 in the case 110 are electrically connected via the terminal of the electronic device 104 and the charging terminal 140.

  With reference to FIG. 9, the structure in case 110 is further demonstrated. As described above, the substrate 120 is accommodated in the case 110. In this embodiment, the substrate 120 is arranged such that the front surface (that is, the right surface in FIG. 9) and the back surface (that is, the left surface in FIG. 9) are directed toward the sides of the case 110, respectively. In other words, in this embodiment, the substrate 120 is disposed along a plane that is substantially perpendicular to the upper surface of the case 110 (that is, the bottom surface of the mounting portion 111). In addition, the board | substrate opening part (refer code | symbol 22 of FIG. 3) is not formed in the board | substrate 120 of a present Example.

  The charging terminal 140 of this embodiment is also formed by processing a metal linear member. A connection portion 146 that is electrically connected to the electronic components of the substrate 120 is provided on one end side of the charging terminal 140. Also in this embodiment, the connection portion 146 is formed in a coil spring shape, and the end portion is inserted into the substrate 120 and fixed. On the other end side of the charging terminal 140, a contact portion 142 that protrudes from the opening 115 of the case 10 into the placement portion 111 (that is, outside the case 110) is provided. As described above, the contact portion 142 can contact the terminal of the electronic device 104 placed (that is, held) on the placement portion 111.

  The linear member constituting the charging terminal 140 is bent from the contact portion 142 toward the connection portion 146. In the present embodiment, a bent portion 143 is formed between the contact portion 142 and the connection portion 146. The lowest part of the bent part 143 is the lower end part 144, and the highest part of the bent part 143 is the upper end part 145. Between the lower end portion 144 and the upper end portion 145 is a slope portion 48, and the height gradually increases from the lower end portion 144 (that is, the contact portion 142 side) toward the upper end portion 145 (that is, the connection portion 146 side) (that is, the ascending slope). Is formed). In the example of FIG. 9, the height of the upper end portion 145 is higher than the height of the connection portion 146. In another example, the height of the upper end portion 145 and the height of the lower end portion 144 may both be higher than the height of the connection portion 146. In this embodiment, when the charging device 102 is viewed in plan, the lower end portion 144 of the charging terminal 140 is disposed outside the substrate 120. In other words, the lower end portion 144 and the substrate 120 are arranged at positions shifted laterally from each other.

  Also in this embodiment, a partition wall 116 is formed inside the case 110. The partition wall 116 is formed integrally with the inner surface of the case 110 and is provided in a lower portion of the charging terminal 140. The partition wall 116 partitions a specific portion 119 that is a portion below the charging terminal 140 inside the case 10 and a portion where the substrate 20 is provided. The specific portion 119 has a through hole 118 that communicates with the outside.

  The configuration of the charging device 102 according to the present embodiment has been described above. As described above, in this embodiment, the charging terminal 140 has the gradient portion 148 between the contact portion 142 and the connection portion 146. Therefore, even if the water adhering to the electronic device 104 mounted on the mounting unit 111 enters the case 110 from the contact unit 142 through the charging terminal 140, the charging terminal The water that travels 140 cannot travel down the gradient portion 148 toward the upper end portion 145 after it travels down from the contact portion 142 to the lower end portion 144. Therefore, the water that has entered the case 110 from the contact portion 142 through the charging terminal 140 falls downward from the lower end portion 144 without flowing from the lower end portion 144 of the gradient portion 148 to the connection portion 146. The dropped water reaches the specific part 19. In the present embodiment, when the charging device 102 is viewed in plan, the lower end portion 144 of the charging terminal 140 is disposed outside the substrate 120. Therefore, the dropped water does not adhere to the substrate 120. That is, according to the present embodiment, the occurrence of a situation where water reaches the connecting portion 146 through the charging terminal 140 and adheres to the electronic component of the substrate 120 is suppressed.

  Also in this embodiment, a partition wall 116 that partitions the specific portion 119 and the portion where the substrate 120 is disposed is provided in the case 110. Therefore, the water that has reached the specific portion 19 is also prevented from flowing to the substrate 120 side. It is possible to more effectively suppress water from adhering to the substrate 120 and the electronic component.

  In the present embodiment, a plurality of through holes 118 are formed in the specific portion 119. Thereby, the water that has reached the specific portion 119 can be discharged out of the case 110.

  As mentioned above, although the Example of this invention was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, the following modifications may be adopted.
