Fourthly, as shown in FIGS. 7C and 8A, when the rotating member 16 is rotated 90 degrees, the second locking portion 49 of the rotating member 16 becomes the relief groove of the housing 12. Enter 30.
Finally, as shown in FIG. 8B, when the first and second locking portions 48 and 49 of the rotating member 16 are slid along the guide portions 24 on both sides in the width direction of the housing 12, the rotation is performed. The member 16 is completely attached to the housing 12, and the rotating object 16 presses the connection object toward the contact 14.
As described above, the rotating member 16 and the housing 12 are brought into contact with each other at a plurality of locations during rotation, thereby providing a click feeling during rotation.

Finally, the fixture 17 will be described. The fixture 17 is made of metal and is manufactured by a known press working. As the material of the fixture 17, spring property, conductivity, and the like are required, and examples thereof include brass, beryllium copper, and phosphor bronze. In this embodiment, the housing 12 is disposed on both sides in the width direction of the mounting portion 18.
The fixture 17 has a substantially plate-like piece. The shape and size of the fixture 17 are appropriately designed in consideration of the holding force of the connector 10 on the substrate, workability, strength, and the like. The fixture 17 is provided with a fixing portion and is fixed by press-fitting.
Further, the fixing tool 17 is provided with an engaging convex portion 26 that engages with the locking hole 50 of the rotating member 16. The engaging convex portion 26 is used for positioning, clicking feeling, and reliable holding when the sliding of the rotating member 16 is completed. The shape and size of the engaging convex portion 26 is appropriately designed in consideration of such a role, click feeling, workability, strength, and the like.

  As an application example of the present invention, it is used for a connector 10 used in an electric device or an electronic device such as a mobile phone, a portable music player, a portable TV, etc., and in particular, downsizing even when an electronic component connected with a cable is mounted. Is related to a possible structure.
