a second plate, disposed at and against a second side of the deformable body;

wherein:

when the deformable body is disposed in the opening, a relative displacement between the first plate and the second plate is used to change a shape of the deformable body such that the deformable body closely fits the opening in order to block moisture and/or dust from entering into the opening.

2. The water-resistant element of claim 1 , further comprising an adjusting element penetrating through the first plate, the deformable body and the second plate, wherein the adjusting element is used to create the relative displacement.

3. The water-resistant element of claim 2 , wherein the adjusting element is a screw bolt, the first plate and the second plate respectively have a first screw hole and a second screw hole corresponding to the screw bolt, and the screw bolt is rotatable relatively to the first screw hole and the second screw hole in order to create the relative displacement.

4. The water-resistant element according to claim 1 , wherein the relative displacement is used to change the shape of the deformable body in a direction perpendicular to the relative displacement.

5. An external connection wire module, comprising:

a water-resistant element, comprising:

a deformable body;

a first plate, disposed at and against a first side of the deformable body; and

a second plate, disposed at and against a second side of the deformable body, wherein a relative displacement between the first plate and the second plate is used to change a shape of the deformable body; and

an external connection wire, penetrating through the first plate, the deformable body and the second plate.

6. The external connection wire module of claim 5 , wherein the water-resistant element further comprises an adjusting element penetrating through the first plate, the deformable body and the second plate, wherein the adjusting element is used to create the relative displacement.

7. The external connection wire module of claim 6 , wherein the adjusting element is a screw bolt, the first plate and the second plate respectively have a first screw hole and a second screw hole corresponding to the screw bolt, and the screw bolt is rotatable relatively to the first screw hole and the second screw hole in order to create the relative displacement.

8. The external connection wire module of claim 5 , wherein the relative displacement is used to change the shape of the deformable body in a direction perpendicular to the relative displacement.

9. The external connection wire module of claim 5 , wherein the external connection wire is a coaxial cable.

10. An antenna box module, comprising:

an antenna box, comprising a housing and a circuit board, wherein the circuit board comprises an antenna and is disposed in the housing; and

an external connection wire module, comprising:

a water-resistant element, comprising:

a deformable body disposed in an opening of the housing;

a first plate, disposed at and against a first side of the deformable body;

a second plate, disposed at and against a second side of the deformable body; and

an adjusting element, that penetrates through the first plate, the deformable body and the second plate and being used to create a relative displacement between the first plate and the second plate; and

an external connection wire, that penetrates through the first plate, the deformable body and the second plate and being electrically connected to the antenna;

wherein the relative displacement is used to change a shape of the deformable body such that the deformable body closely fits the opening in order to block moisture and/or dust from entering into the opening.

11. The antenna box module of claim 10 , wherein the adjusting element is a screw bolt, the first plate and the second plate respectively have a first screw hole and a second screw hole corresponding to the screw bolt, and the screw bolt is rotatable relatively to the first screw hole and the second screw hole in order to create the relative displacement.

12. The antenna box module of claim 10 , wherein the relative displacement is used to change the shape of the deformable body in a direction perpendicular to the relative displacement.

13. The antenna box module of claim 10 , wherein the external connection wire is a coaxial cable.

14. A method of fixing a water-resistant element at a housing, comprising:

a) providing the water-resistant element, comprising:

a deformable body;

a first plate, disposed at and against a first side of the deformable body;

a second plate, disposed at and against a second side of the deformable body; and

an adjusting element, penetrating through the first plate, the deformable body and the second plate;

b) placing the deformable body in an opening of the housing; and
