fig. 2 is a front view of the rubber cover of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further explained with reference to the specific drawings.
Referring to fig. 1, tail-gate handle pencil waterproof construction, including casing 1, be equipped with rubber cover 2 on the open portion of casing 1, rubber cover 2 is for adopting rubber material injection moulding to make rubber cover 2, and rubber cover 2 is separated the casing 1 inside and outside for dry district and wet district. The rubber cover 2 is provided with at least one rubber cover hole 21, and the joint of the rubber cover 2 and the shell 1 is wound with a rubber cloth 3. The adhesive fabric 3 is a waterproof insulating adhesive fabric 3. So as to achieve the purposes of water resistance and insulation.
The utility model discloses cover the dry district that separates inside and outside casing 1 and wet district junction part through rubber injection moulding's rubber boot 2 in order to reach waterproof purpose. A plurality of rubber cover holes 21 on the rubber cover 2 are used for threading or threading, and the rubber cover 2 is made of rubber injection molding materials, so that the rubber cover has certain elasticity, the rubber cover holes 21 can be made slightly smaller, and after the threads or the pipes penetrate under the action of the elasticity, the threads or the pipes can be tightly attached to the inner wall of the rubber cover holes 21, so that the aim of water prevention is further fulfilled.
Referring to fig. 2, five rubber cover holes 21 are formed in the rubber cover 2, three rubber cover holes 21 are wire through holes, one rubber cover hole 21 is a water pipe hole, and one rubber cover hole 21 is a camera signal wire hole. The requirement of the automobile tail door handle wire harness is met.
