Abstract
The invention discloses a watertight 90-degree three-face wrapping connector. The watertight 90-degree three-face wrapping connector comprises a polytetrafluoroethylene sponge core and a rubber skin for conducting three-face wrapping on the sponge core. The sponge core comprises a first body, a second body perpendicular to the first body, and a third body which is connected between the first body and the second body. The first body, the second body and the third body are connected in an end-to-end mode. The included angle between the third body and the first body is 135 degrees. The included angle between the third body and the second body is also 135 degrees. A corner space is defined by the first body, the second body and the third body. The sponge core is provided with a body part with the rectangular section, and a protruding part, the protruding part protrudes from the inner side of the body part to the interior of the corner space, and the section of the protruding part is in an isosceles trapezoid shape. The rubber skin is composed of a first skin body, a second skin body, a third skin body and a fourth skin body. According to the watertight 90-degree three-face wrapping connector, a polytetrafluoroethylene sealing material is adopted, and the physical and mechanical properties are further improved on the basis of maintaining the original excellent properties.
