Referring to fig. 1 to 6, the anti-drop plug for the electric vehicle charger comprises a panel 51, a mounting shell 52, a mounting post 53, a contact block 54, a torsion spring 55 and a socket with a plug-in sheet 61 and an insulation head 62.

The mounting shell 52 is fixedly connected to the panel 51, four mounting columns 53 are fixed in the mounting shell 52, the four mounting columns 53 are vertically arranged, each mounting column 53 is connected with one contact block 54 and one torsion spring 55 in an inserting mode, the contact block 54 is located above the torsion spring 55 on each mounting column 53, one end of the torsion spring 55 is clamped on the contact block 54, and the other end of the torsion spring 55 is clamped on the inner wall of the mounting shell 52. The two contact blocks 54 form one electrical contact.

Two insertion grooves 511 are provided on the panel 51, the two insertion grooves 511 are vertically provided, and the two insertion grooves 511 are correspondingly arranged on the rear sides of the two electrical contacts. Each plug sheet 61 in the socket is inserted between two contact blocks 54 in the corresponding electric contact body by the plug groove 511 at the corresponding position, the contact blocks 54 are tightly pressed on the plug sheet 61 by the torsion spring 55, and the insulation head 62 of the socket is arranged on the outer side of the panel 51.

The insertion slot 511 and the mounting post 53 are vertically arranged, the height of the insertion slot 511 is larger than that of the contact block 54, and the bottom surface of the insertion slot 511 is flush with that of the contact block 54. When the insertion piece 61 is inserted between the contact blocks 54, the insertion piece 61 is inserted from above the insertion slot 511, and at this time, the insertion piece 61 is not in contact with the electric contact. The insert 61 is then slid downward in the slot 511 until the insert 61 abuts the bottom surface of the slot 511, at which point the insert 61 snaps into place between the two contact blocks 54 in the electrical contact.

The contact block 54 is a rectangular block structure, a through hole is formed in the rear end of the contact block 54, and the mounting column 53 penetrates through the through hole of the contact block 54. In order to conveniently and exactly clamp the insertion sheet 61 between the two contact blocks 54 in the electric contact body, the front end surface of each contact block 54 is of an arc surface structure, and the arc surface of each contact block 54 is abutted against the insertion sheet 61.

The arc surface of the contact block 54 is provided with anti-slip lines. The non-slip threads may increase the friction between the contact block 54 and the insert 61.

To facilitate axial positioning of the contact block 54 on the mounting post 53, a step surface is provided on the mounting post 53 that axially positions the contact block 54 on the mounting post 53 such that the bottom surface of the contact block 54 is flush with the bottom surface of the insertion slot 511. Alternatively, a spring may be engaged with the mounting post 53, and the contact block 54 may be axially positioned on the mounting post 53 by the spring.
