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 accommodated in the housing 1 such that the normal direction thereof is the vertical direction (direction intersecting the insertion direction). In other words, the normal direction of the second substrate 6 is a direction crossing the insertion direction. As described above, since the normal direction of the second substrate 6 intersects the insertion direction, compared with the case where the normal direction of the second substrate 6 is a direction along the insertion direction, The housing 1 can be reduced in size in the direction crossing 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.

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 direction. In other words, the direction of stress applied from the first outer terminal 18 when connecting the first outer terminal 18 to the first inner terminal 8 and the second direction when connecting the second outer terminal 19 to the second inner terminal 9. The direction of the stress applied from the outer terminal 19 is the same direction. Therefore, the structure for receiving the stress applied from the first outer terminal 18 and the second outer terminal 19 is one direction (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 is only necessary to provide it. As a result, the structure can be simplified as compared with the case where the direction of stress applied from the first outer terminal 18 is different from the direction of stress applied from the second outer terminal 19.

What is necessary is just to have one side wall part. Moreover, the side wall part should just be covered with the surface in the longitudinal direction of 1 side corresponding among the 4 sides of the mounting surface 400 of the support part 41 by the surface.
