  After storing the release button 12 in the button storage section 221 of the third storage section 22, the operator stores the second substrate 6 in the second storage section 21 of the body 2, and stores the third substrate 7 in the third storage section. It is stored in the section 22. At this time, both ends of the main portion 61 of the second substrate 6 in the left-right direction are inserted into the pair of holding grooves 210, respectively. At this time, the two second inner terminals 9 (including the corresponding locking springs 11) mounted on the third substrate 7 are respectively stored in the two terminal storage sections 220 of the third storage section 22. You. The third substrate 7 is placed on the front end face of the third storage portion 22 so that the normal direction thereof extends along the front-back direction.

Next, the worker places the support member 4 on the body 2 so as to cover the second substrate 6 (see FIG. 7). At this time, the two pressing portions 420 of the supporting member 4 contact the first supporting portion 211 of the body 2 from the front (the first substrate 5 side), and the pressing portion 450 contacts the second supporting portion 212 from the front. At this time, one of the two pressing portions 430 contacts the third supporting portion 213 from the front, and the other contacts the fourth supporting portion 214 from the front. Further, at this time, the holding portions 421, 4
31 and 440 contact the surface (front surface) of the third substrate 7 from the front. Here, in the present embodiment, the contact portions are configured by the holding portions 420, 430, and 450.

  When the support member 4 is placed on the body 2, a part of the second substrate 6 is placed in a space surrounded by the support portion 41, the lower wall portion 42, the upper wall portion 43, the left wall portion 44, and the right wall portion 45. Is stored. That is, in the present embodiment, the storage portion 46 is configured by a space surrounded by the support portion 41, the lower wall portion 42, the upper wall portion 43, the left wall portion 44, and the right wall portion 45. In other words, the storage portion 46 is provided between the support portion 41 and the contact portion in the insertion direction (front-back direction) of the first outer terminal 18 into the first inner terminal 8.

  Subsequently, the operator fixes the first substrate 5 to the support portion 41 of the support member 4. At this time, the three positioning protrusions 412 provided on the support portion 41 are fitted into the three positioning holes 53 provided on the first substrate 5 respectively. At this time, the electronic component 15 arranged on the second surface 52 of the first substrate 5 is passed through the component insertion hole 411, and the connection pin of the first inner terminal 8 exposed on the second surface 52 side is inserted into the opening hole 410.

  The first substrate 5 and the third substrate 7 are housed in the housing 1 such that the normal direction is the front-back direction (the direction in which the first outer terminal 18 is inserted into the first inner terminal 8). In other words, the normal direction of the first substrate 5 and the third substrate 7 is a direction along the insertion direction. The second substrate 6 is housed in the housing 1 such that the normal direction is the vertical direction (the direction intersecting the insertion direction). In other words, the normal direction of the second substrate 6 is a direction that intersects the insertion direction. As described above, since the normal direction of the second substrate 6 intersects with the insertion direction, the normal direction of the second substrate 6 is smaller than the case where the normal direction is along the insertion direction. The size of the housing 1 can be reduced in a direction intersecting with the insertion direction.

  The third substrate 7 is located behind the protrusion 62 of the second substrate 6 in the front-rear direction (the vertical direction in FIG. 8). In other words, the third substrate 7 is located between both ends of the second substrate 6 in the front-back direction. In other words, the third substrate 7 is located between both ends of the second substrate 6 in the insertion direction. Thus, by arranging the third substrate 7 between both ends of the second substrate 6 in the front-back direction, the third substrate 7 is arranged outside (front side or lower side) than both ends of the second substrate 6 in the front-back direction. The size of the housing 1 can be reduced in the front-rear direction, as compared with the case in which the housing 1 is used.

In other words, the first substrate 5 is located between the second substrate 6, which is closer to the first insertion hole 320, of the second substrate 6 and the third substrate 7 and the first insertion hole 320. Thus, by disposing the first substrate 5 between the second substrate 6 and the first insertion hole 320 in the front-rear direction, the first substrate 5 and the second substrate 6 are arranged side by side in the front-rear direction. The housing 1 can be downsized in a direction intersecting with the front-rear direction as compared with the case of FIG.

  According to the seventh aspect, the direction of the stress applied from the first outer terminal 18 when the first outer terminal 18 is connected to the first inner terminal 8 and the second outer terminal 19 is connected to the second inner terminal 9. In this case, the direction of the stress applied from the second outer terminal 19 becomes the same direction. In other words, the direction of the stress applied to the wiring device 10 can be limited to one direction (insertion direction). Therefore, a structure for receiving the stress applied from the first outer terminal 18 and the second outer terminal 19 only needs to be provided in one direction, and the direction of the stress applied from the first outer terminal 18 and the The structure can be simplified as compared with the case where the direction of the applied stress is different. However, this configuration is not an essential configuration of the wiring device. For example, the second insertion hole may be provided at an end of the housing in a direction intersecting with the insertion direction.

  In the wiring device 10 according to the eighth aspect, in any of the first to seventh aspects, the first inner terminal 8 is a USB socket.

  According to the eighth aspect, a USB plug can be connected. However, this configuration is not an essential configuration of the wiring device. For example, the first inside terminal may be a LAN terminal.
