Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example (b): the utility model provides a connecting piece of electric vehicle charging device, as shown in fig. 1, includes socket 1 and plug 2, has seted up on the socket 1 and has supplied plug 2 laminating male slot 11, has seted up storage tank 21 in the middle of the plug 2, is provided with three pins 22 in the storage tank 21, is provided with three in the slot 11 and supplies pin 22 to laminate male socket 12 respectively, and the integration is provided with the insulating cover 13 of cladding outside socket 12 in the slot 11, and the terminal surface protrusion of insulating cover 13 is in the port of socket 12. Socket 1 installs on the electric motor car, and insulating cover 13 will insert a section of thick bamboo 12 and external isolated, and the port of inserting a section of thick bamboo 12 simultaneously is sunken in insulating cover 13, and the people can only touch insulating cover 13, can't touch and insert a section of thick bamboo 12, has avoided the people to electrocute, has realized the function of preventing the mistake and touching.

As shown in fig. 1, the insulating sleeve 13 and the receiving groove 21 have the same shape, and the insulating sleeve 13 is fit and inserted into the receiving groove 21. The receiving groove 21 guides the insulating sleeve 13 to ensure that the pins 22 are accurately inserted into the socket 12. Meanwhile, the gap between the socket 1 and the plug 2 can be broken through the matching of the insulating sleeve 13 and the accommodating groove 21, so that external water is prevented from entering the socket 1 and wetting the plug cylinder 12 and the pins 22, and the sealing and waterproof performance is improved.

As shown in fig. 1, the end surface of the insulating sheath 13 is rounded. After the end face of the insulating sleeve 13 is rounded, the area of the end face of the insulating sleeve 13 is smaller than the accommodating groove 21, so that the insulating sleeve 13 is ensured to be smoothly inserted into the accommodating groove 21, and meanwhile, the friction force between the plug 2 and the socket 1 can be further reduced.

As shown in fig. 1, the upper part of the socket 1 is hinged with a cover 3, a torsion spring is sleeved on a rotating shaft of the cover 3, the torsion spring makes the cover 3 have a tendency of covering the socket 1, and the cover 3 is larger than the opening size of the slot 11. When the plug 2 is not inserted into the socket 1, the covering part 3 can seal the socket 1, so that the sealing performance of the slot 11 is ensured, the external dust is prevented from being accumulated in the plug barrel 12, the pin 22 and the plug barrel 12 are prevented from being in poor contact, and the sealing performance is improved.

As shown in fig. 1, a shifting block 31 extends from the end of the cover 3 remote from the hinge. The user can drive whole 3 rotations that cover through stirring shifting block 31, avoids covering 3 and protrudes the part of socket 1 and is too short, and the inconvenient rotation of user covers 3, has improved easy and simple to handle nature.

As shown in fig. 1 and fig. 2, a stopper 32 is disposed on the cover 3, a stopper groove 23 for the stopper 32 to insert into is recessed on the plug 2, and the stopper 32 is used for preventing the plug 2 from leaving the socket 1. Insert socket 1 with plug 2 after, cover 3 and laminate plug 2 upper surface under the effect of torsional spring, stopper 32 inserts limiting groove 23 this moment in, when plug 2 has the trend of leaving outward, stopper 32 will the butt limiting groove 23, hinders stopper 32 and leaves, has realized plug 2 and socket 1's relatively fixed, when avoiding charging, plug 2 breaks away from, has improved the connection steadiness. The fixing of the plug 2 is realized without the help of the friction force between the plug 2 and the socket 1, and the labor consumed when a user pulls and inserts the plug 2 is reduced.

As shown in fig. 2, the side wall of the limiting groove 23 close to the port of the plug 2 is perpendicular to the plug 2, and the end face of the limiting block 32 is attached to the side wall. After the limiting block 32 is shifted to the limiting groove 23, the limiting block 32 can be attached to the limiting groove 23, and when the limiting groove 23 wants to be far away from the socket 1, the limiting block 32 can abut against the limiting groove 23 to prevent the plug 2 from moving.
