It is stored in the part 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 lock spring 11) mounted on the third substrate 7 are respectively housed in the two terminal storage portions 220 of the third storage portion 22. To. The third substrate 7 is placed on the front end surface of the third accommodating portion 22 so that its normal direction is along the front-rear direction.

Next, the operator 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 support member 4 come into contact with the first supporting portion 211 of the body 2 from the front (on the side of the first substrate 5), and the pressing portion 450 comes into contact with the second supporting portion 212 from the front. At this time, one of the two pressing portions 430 comes into contact with the third supporting portion 213 from the front, and the other contacts the fourth supporting portion 214 from the front. Furthermore, at this time, the holding portions 421 and 4
31,440 come into contact with the surface (front surface) of the third substrate 7 from the front. Here, in the present embodiment, the contact portion is composed of the pressing portions 420, 430, 450.

When the support member 4 is mounted on the body 2, a part of the second substrate 6 is in a space surrounded by the support portion 41, the lower side wall portion 42, the upper side wall portion 43, the left side wall portion 44, and the right side wall portion 45.

The first substrate 5 and the third substrate 7 are housed in the housing 1 so that the normal direction thereof is the front-rear direction (the insertion direction of the first outer terminal 18 with respect to 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. Further, the second substrate 6 is housed in the housing 1 so that its 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 the insertion direction, the above is compared with the case where the normal direction of the second substrate 6 is along the insertion direction. The housing 1 can be miniaturized in the direction intersecting the insertion direction.

The third substrate 7 is located behind the protrusion 62 of the second substrate 6 in the front-rear direction (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-rear direction.

In other words, the first substrate 5 is located between the second substrate 6 and the first insertion hole 320, which of the second substrate 6 and the third substrate 7 is closer to the first insertion hole 320. In this way, when the first substrate 5 is arranged 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 miniaturized in the direction intersecting the front-rear direction.

That is, the direction in which the first outer terminal 18 is inserted into the first inner terminal 8 and the direction in which the second outer terminal 19 is inserted into the second inner terminal 9 are the same. In other words, the direction of the stress applied from the first outer terminal 18 when connecting the first outer terminal 18 to the first inner terminal 8 and the second when connecting the second outer terminal 19 to the second inner terminal 9. The direction of stress applied from the outer terminal 19 is the same. Therefore, the structure for receiving the stress applied from the first outer terminal 18 and the second outer terminal 19 is unidirectional (the insertion direction of the first outer terminal 18 with respect to the first inner terminal 8, that is, upward and downward in FIG. 8). It only needs to be provided in. As a result, the structure can be simplified as compared with the case where the direction of the stress applied from the first outer terminal 18 and the direction of the stress applied from the second outer terminal 19 are different.

According to the third aspect, the first substrate 5 is located between the substrate closer to the insertion hole and the insertion hole in the insertion direction. Therefore, the housing 1 can be miniaturized in the direction intersecting the insertion direction as compared with the case where the substrate and the first substrate 5 are arranged side by side in the direction intersecting the insertion direction. However, this configuration is not an essential configuration of the wiring device, and the first substrate may not be located between the substrate closer to the insertion hole in the insertion direction and the insertion hole.

Therefore, it is only necessary to provide a structure for receiving the stress applied from the first outer terminal 18 and the second outer terminal 19 in one direction, and the stress is applied from the first outer terminal 18 and the second outer terminal 19. The structure can be simplified as compared with the case where the direction of stress is different. However, this configuration is not an essential configuration of the wiring device, and for example, the second insertion hole may be provided at the end of the housing in the direction intersecting the insertion direction.

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

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