It enters between a pair of contact portions 32 d formed on the outer receptacle contact member 32 held by the main body portion 10. Further, the contact portion 72 a of the inner plug contact member 72 held by the plug main body portion 50 enters between a pair of contact portions 42 d formed on the inner receptacle contact member 42 held by the receptacle main body portion 10.

  At this time, the contact portion 71a of the outer plug contact member 71 is embedded and fixed in the right outer intervention portion 61 and the left outer intervention portion 62 formed integrally with the plug main body portion 50, so that the contact portion 71a is fixed. Without being elastically deformed, the pair of contact portions 32d formed on the outer receptacle contact member 32 is elastically deformed so as to open to each other. Further, since the contact portion 72a of the inner plug contact member 72 is embedded and fixed in the right inner intervention portions 63a and 63b and the left inner intervention portions 64a and 64b, the contact portion 72a is not elastically deformed and the inner receptacle. The pair of contact portions 42d formed on the contact member 42 is elastically deformed so as to open.

  The contact portion 71a of the outer plug contact member 71 and the contact portion 72a of the inner plug contact member 72 do not cause elastic distortion in the Y direction, and the contact portion 32d of the outer receptacle contact member 32 and the inner receptacle contact member 42 sandwich the sandwiched portion. Since the contact portion 42 d is elastically deformed, the contact portion 32 d of the outer plug contact member 71 and the contact portion 72 a of the inner plug contact member 72 are formed by the contact portion 32 d of the outer receptacle contact member 32 and the contact portion 42 d of the inner receptacle contact member 42. Can be reliably held with an appropriate elastic force.

  As shown in FIG. 4, in the contact grooves 25, 26, 27a, 27b, 28a, and 28b of the receptacle main body 10, a pair of contact portions 32d and a pair of contact portions 42d can be deformed in a direction of widening the interval. Thus, a movement margin δ is provided. Therefore, when the plug-side contact portion 71a is sandwiched between the pair of contact portions 32d and the plug-side contact portion 72a is sandwiched between the pair of contact portions 42d, the contact portions 32d and 42d are connected to Y1-Y2. The plug-side contact portions 71a and 72a can be held at a sufficient depth by the receptacle-side contact portions 32d and 42d.

  Further, when the plug-side contact portions 32d and 42d are sandwiched between the receptacle-side contact portions 32d and 42d, and the contact portions 32d and 42d spread in the Y1 direction and the Y2 direction, the contact portions 32d and 42d are in contact with each other. It is preferable that the groove 25, 26, 27a, 27b, 28a, 28b hits the back end of the Y1 side or Y2 side. That is, even when the movement allowance δ becomes zero, it is preferable that the paired contact portions 32d and the paired contact portions 42d are further deformed in the direction of spreading. Since the contact portions 32d and 42d are deformed even after they hit the back end portion, the pair of contact portions 32d and 42d can hold the receptacle-side contact portions 32d and 42d, which do not deform themselves, with a strong force. .

  In the plug-side connector 2, the inner surface 61a of the right outer intervention portion 61 and the outer surface of the contact portion 71a are substantially the same surface, and the inner surface 62a of the left outer intervention portion 62 and the outer surface of the contact portion 71a are substantially the same surface. Further, both side surfaces 63c, 63d of the right inner intervention portions 63a, 63b and the outer surface of the contact portion 72a are the same surface, and the left inner intervention portions 64a, 64b and the outer surface of the contact portion 72a are substantially the same surface. Therefore, when the plug main body 50 is mounted on the receptacle main body 10, the plug-side contact portions 71a and 72a are caught between the receptacle-side contact portions 32d and 32d and between the contact portions 42d and 42d. Will be able to intervene smoothly.

  As shown in FIG. 8, a latching contact member 73 is embedded in the front-rear direction (X1-X2 direction) end of the right outer intervention part 61 of the plug main body 50, and the left outer intervention part 62 extends in the front-rear direction. A latching contact member 73 is also embedded at the end. The latch contact member 73 has an embedded portion 73a embedded in the right outer intervention portion 61 and the left outer intervention portion 62, and a terminal portion 73b protruding outward from the right side surface 53 and the left side surface 54 of the plug body 50. ing. In the embedded portion 73a, a claw portion 73c protruding from the right side surface 53 in the Y1 direction and a claw portion 73c protruding from the left side surface 54 in the Y2 direction are integrally formed.

  The terminal portion 73b is soldered to any land portion such as a flexible wiring board, and is preferably soldered to a land portion having a ground potential.

  When the plug main body 50 is attached to the receptacle main body 10, the claw 73c is elastically hooked on the curved contact portions 33a and 34a provided at the four locations of the receptacle main body 10. Stopped. The plug main body 50 is fitted so as not to easily come out of the receptacle main body 10 by the latching mechanism by the four claw portions 73c.
