The plug 70 is a member for electrically connecting a wire to an electric device (not shown), and mainly includes a plug terminal formed of a conductor that is fitted into a retaining socket. The anti-drop socket is provided with a contact piece which is embedded with the plug terminal. The housing 10 is a box body for housing the electric component 11, and includes a front side and a front side socket 12 for retaining the socket, and the socket 12 has a socket insertion hole into which the plug 70 is inserted. The electric component 11 and the retaining piece 20 are both housed in the housing cavity 101 of the housing 10.

In the conventional art, the anti-release sheet 20 is formed by connecting three sets of elastic arms having a U-shaped structure with their openings facing downward, and when the plug 70 is connected to the contact piece arranged inside the housing 10 and electrically connected to the electric component 11, the plug 70 is held by the anti-release sheet 20, and the plug 70 is prevented from being released from the inserted socket 12.

The floating holder 30 is provided in the housing cavity 101, and includes a floating cavity 301 controlled by the unlocking mechanism 40, and as can be seen from fig. 8, the floating cavity 301 has a substantially trapezoidal structure as shown in the drawing, and the separation preventing piece 20 is restricted in the floating cavity 301, and for example, by enlarging the floating cavity 301, the user can slide the unlocking mechanism 40 to enlarge the size of the floating cavity 301, so that the separation preventing piece 20 can be deflected in the enlarged floating cavity 301, and the lock of the plug 70 is released. Fig. 7 and 9 are views showing a state where the plug 70 is kept locked, and fig. 10 is a view showing a state where the plug is under contact locking.

The elastic member 50 is a part for connecting the floating holder 30 and the housing 10, and includes a guide post 51 and a spring 52, and the guide post 51 and the spring 52 can elastically deform the elastic member 50 by integrally connecting the floating holder 30 and the seat 12.
