Further, at least one of the first elastic arm 1152 and the second elastic arm 1153 is bent and protrudes from the side of the main body 1151 facing the waterproof and breathable module 113. Furthermore, the first elastic arm 1152 and the second elastic arm 1153 are axially symmetrically connected to the main body 1151. The pressing plate 115 of this structure has a simple structure and is easy to process and shape to realize mass production. For the first elastic arms 1152 and the second elastic arms 1153 that are arranged axisymmetrically on both sides of the main body portion 1151, the side of the first boss 111a facing the bottom of the mounting groove 105, and the second boss 111b facing the mounting groove One side of the groove bottom of the 105 can be flush, so that the main body 1151 can be arranged substantially parallel to the groove bottom of the installation groove 105, so that the waterproof and breathable membrane 113a is uniformly stressed.

7 and 8, the distance between the first boss 111a and the second boss 111b is d1, the distance between the end of the first elastic arm 1152 and the end of the second elastic arm 1153 is d2, and d1 is smaller than d2. 9 at the same time, in the process of assembling the pressing plate 115 and the housing 111, the first elastic arm 1152 can be inserted into the first interval 111c, and then the pressing plate 115 can be rotated with the first boss 111a as a fulcrum to make the second The elastic arm 1153 approaches and abuts the second boss 111b; when the second elastic arm 1153 is continuously pressed, the second elastic arm 1153 is elastically deformed and passes over the second boss 111b to enter the second interval 111d. Using the reaction force of the waterproof and breathable module 113 on the pressure plate 115, the first elastic arm 1152 can press against the first boss 111a, and the second elastic arm 1153 can press against the second boss 111b, so that the pressure plate 115 is pressed against the waterproof and breathable The module 113 restricts the movement of the pressing plate 115 along its thickness direction through the first boss 111a and the second boss 111b. The above-mentioned matching structure of the mounting groove 105 and the pressing plate 115 simplifies the assembly of the pressing plate 115 and the housing 111, and improves the assembly efficiency while ensuring the pressing reliability of the pressing plate 115 against the waterproof and breathable membrane 113a.

Further, a coordinate system is established by taking the length direction of the mounting groove 105 as the X axis, the width direction as the Y axis, and the depth direction as the Z axis. 7 and 8, the width of the mounting groove 105 is D1, d2 is smaller than the width D1 of the mounting groove 105, that is, in the extension direction of the X-axis, the two opposite side walls of the mounting groove 105 do not generate a line along the X-axis against the pressure plate 115 The squeezing force in the direction can prevent the main body 1151 of the pressure plate 115 from being deformed and protruding to the side (Y-axis direction) away from the air hole 107, so as to ensure that the pressure plate 115 is reliably pressed against the waterproof and breathable module 113. sex. This structural arrangement can also prevent the pressure plate 115 from generating a tangential shear force on the waterproof and breathable module 113 due to the pressing force along the width direction of the installation groove 105 (X-axis direction), which can further ensure that the pressure plate 115 is against the waterproof and breathable mold. The reliability of the pressure resistance of the group 113 prevents the waterproof and breathable membrane 113a from being damaged by shearing force during the assembly process.

Further, referring to FIG. 8, the pressing plate 115 further includes a first extension arm 1154 and a second extension arm 1155 extending from opposite ends of the main body portion 1151. The first extension arm 1154 and the first elastic arm 1152 are located on the main body portion 1151. The second extension arm 1155 and the second elastic arm 1153 are located at the same end of the main body 1151, and the side wall of the mounting groove 105 can limit the moving range of the first extension arm 1154 and the second extension arm 1155. Specifically, referring to FIG. 8, the distance between the end of the first extension arm 1154 and the end of the second extension arm 1155 is D2. With reference to FIG. 7, the difference between D1 and D2 is less than or equal to 1 mm. For example, the difference between D1 and D2 can be 0, or 0.1 mm, or 0.2 mm, or 0.3 mm, or 0.5 mm, or 0.8 mm, or 1 mm, etc. In the above arrangement, in the X-axis direction, the side walls of the mounting groove 105 restrict the movement of the pressing plate 115 in the X-axis direction through the first extension arm 1154 and the second extension arm 1155, and the two opposite side walls of the mounting groove 105 do not align with the pressing plate 115 Generate a pressing force along the width direction (X-axis direction) of the mounting groove 105, thereby preventing the main body 1151 of the pressure plate 115 from being deformed under pressure and protruding toward the side away from the air hole 107, thereby ensuring that the pressure plate 115 is against the waterproof and breathable mold. Reliability of group 113 against pressure. This structural arrangement can also prevent the pressure plate 115 from generating tangential shearing force on the waterproof and breathable module 113 due to the pressing force along the width direction of the installation groove 105, which can further ensure that the pressure plate 115 resists the waterproof and breathable module 113. The reliability can prevent the waterproof and breathable membrane 113a from being damaged by shearing force during the assembly process. In particular, since the first elastic arm 1152 and the second elastic arm 1153 need to withstand elastic deformation, their size may change. The first extension arm 1154 and the second extension arm 1155 that do not bear the squeezing force are used to restrict the pressing plate 115 in the mounting groove. After the movement of 105 in the X-axis direction, the first elastic arm 1152 and the second elastic arm 1153 do not need to bear the limit function in the X-axis direction, so the reliability of the pressing plate 115 against the waterproof and breathable module 113 can be further ensured.

Furthermore, both the first extension arm 1154 and the second extension arm 1155 are bent and protruded from the side of the main body 1151 facing the waterproof and breathable module 113. This structure, combined with the structure of the first elastic arm 1152 and the second elastic arm 1153 protruding from the main body 1151 facing the waterproof and breathable module 113, can be formed on the pressure plate 115 facing the waterproof and breathable module 113 for accommodating The recessed area of the waterproof and breathable module 113 is arranged, and the recessed area is then used to realize the preliminary positioning during the assembly of the waterproof and breathable module 113 and the pressure plate 115, thereby improving the convenience and reliability of assembly.
