Detailed Description

As shown in fig. 1 and 4, the present invention includes a rubber boot body 1 and a vehicle charging gun 2 coupled to the rubber boot body 1. Car rifle 2 that charges includes rifle head 3, and the one end of rifle head 3 is fixed with charging plug 4, has seted up the internal thread on the inner wall of the other end of rifle head 3, and charging plug 4 is inside to be fixed with a plurality of contact pins 5, and 3 internal connection of rifle head has charging wire 6, and charging wire 6 extends to rifle head 3 outsidely. As shown in fig. 1 to 3, the rubber protection cover body 1 includes a protection cover 7 matched with the charging plug 4, the inside of the protection cover 7 is fixed with a plurality of slots 8 arranged corresponding to the pins 5 one to one, so as to ensure that the protection cover 7 can be tightly matched with the charging plug 4, thereby improving the rainproof and dustproof effects. Be fixed with elastic connection rope 9 on the outer wall of protective cover 7, elastic connection rope 9 deviates from the one end of protective cover 7 and is fixed with the protection machanism that is used for protecting rifle head 3 and the junction of charging wire 6. Protection machanism includes the protection sleeve 10 that both ends opening set up, the installation cavity 11 that is used for supplying charging wire 6 to pass through is offered along its length direction to the inside of protection sleeve 10, the fixed cover in periphery of protection sleeve 10 one end is equipped with collar 12, elastic connection rope 9 is fixed on collar 12's outer wall, elastic connection rope 9 is close to collar 12's one end and is the spring form, the deformation volume when increase elastic connection rope 9 receives tensile, avoid elastic connection rope 9 to be broken by the stretch, increase of service life. The periphery of the one end of protection sleeve 10 that is close to collar 12 is provided with the external screw thread with internal thread matched with, and protection sleeve 10 is close to the one end threaded connection of collar 12 inside rifle head 3.
