Single piece water resistance door

1. A single piece water resistance door suitable for being fixed to a casing of a connector module, the casing comprising a first engagement part and an opening adjacent to the first engagement part, the single piece water resistance door comprising:

a body, adapted to cover the opening, and comprising at least one second engagement part corresponding to the first engagement part;

an elastic member, wherein the casing comprises a flat surface enclosed by a ring-shaped stopper, the opening being provided on the flat surface, wherein the ring-shaped stopper surrounds the flat surface and the opening, covers peripheries of the opening and pushes against the elastic member, so as to prevent external liquid from entering the connector module through the opening, wherein each of the opening and the ring-shaped stopper is rectangular or rectangular with rounded corners; and

a fixing part for being fixed to the casing, the fixing part having

a first portion, adapted to move along a direction of a force applied on the first portion towards a space between the first portion and the casing, and connected to the body such that, when the force is applied on the first portion, the second engagement part is driven substantially along the direction of the force so as to be released from the first engagement part,

wherein the body and the fixing part are rotatably connected to each other; and

wherein when the second engagement part is engaged with the first engagement part, the casing and the body press against each other, and the body covers the opening.

2. The single piece water resistance door as recited in claim 1 , wherein the second engagement part is a locking hook, and the locking hook is oriented toward a direction opposite to the direction of the force applied to the first portion.

3. The single piece water resistance door as recited in claim 1 , wherein the second engagement part is a locking hook, and a depth of the space is greater than a depth of the locking hook.

4. The single piece water resistance door as recited in claim 1 ,

the elastic member is placed at the body corresponding to the ring-shaped stopper.

5. The single piece water resistance door as recited in claim 1 ,

wherein when the second engagement part is engaged with the first engagement part, the elastic member is placed at the casing corresponding to the ring-shaped stopper.

6. The single piece water resistance door as recited in claim 1 , further comprising:

a pivot part arranged between the fixing part and the body.

7. The single piece water resistance door as recited in claim 6 , wherein the fixing part, the pivot part, and the body are integrally formed, and a thickness of the pivot part is less than a thickness of the fixing part and less than a thickness of the body.

8. The single piece water resistance door as recited in claim 1 , wherein the body further comprises a puller away from the fixing part.

9. The single piece water resistance door as recited in claim 1 , wherein the casing and the body further comprise a plurality of strengthened ribs respectively connected to the first engagement part and the second engagement part.

10. The single piece water resistance door as recited in claim 1 , wherein a material of the single piece water resistance door is plastic.

11. The single piece water resistance door as recited in claim 1 , wherein the body is equipped with a puller away from the fixing part so that a user presses the first portion and directly moves the puller to open the single piece water resistance door.

12. The single piece water resistance door as recited in claim 1 , wherein when the force is applied to the first portion of the fixing part, the first portion of the fixing part is deformed and is moved to the space, and is moved in a downward direction, so as to drive the body to move such that the second engagement part is released from the first engagement part.

13. The single piece water resistance door as recited in claim 1 , wherein the body is equipped with a puller away from the fixing part, and the puller is protruded from a surface of the body so that a user directly moves the puller to open the body.
