When the groove projecting portion 54 c is retracted from the opening of the jig insertion groove 38, the housing portion projecting portion 54 b is also retracted from the opening of the electronic component housing portion 31.

  Next, the jig 97 is inserted into the jig insertion groove 38, the claw portion 97 a of the jig 97 is hooked on the end surface of the electronic component 90, and the sub-removal prevention portion 56 is pressed with a finger or the like. Release the lock.

  Finally, when the jig 97 is pulled out from the jig insertion groove 38, the electronic component 90 is pulled out from the electronic component housing portion 31 together with the jig 97.

  According to this embodiment, since the housing portion overhanging portion 54b of the removal preventing portion 54 and the hooking portion 56b of the auxiliary removal preventing portion 56 overhang the opening of the electronic component housing portion 31, for example, a digital camera equipped with a connector When an impact is applied to (not shown), the housing portion overhanging portion 54b and the hooking portion 56b prevent the electronic component 90 from protruding from the opening of the electronic component housing portion 31.

  The first ground contact portion 52 of the shell 50 is in contact with the first ground electrode portion 90 a of the electronic component 90, and the second ground contact portion 55 of the shell 50 is in contact with the second ground electrode portion 90 b, respectively. Since the ground connection portion 53 is connected to the ground pad 95a of the printed circuit board 95, noise from the outside of the connector affects the electronic component 90, or electromagnetic waves generated in the electronic component 90 leak to the outside of the connector. Can be prevented.

  Further, the shell 50 is provided with one first ground contact portion 52, one second ground contact portion 55, and three first ground connection portions 53, and the two first ground contact portions 52 and one second ground contact.
