[0017] The disclosure of this application will become more readily understood with reference to the accompanying drawings. It will be readily understood by those skilled in the art that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of this application. Furthermore, similar numbers in the drawings are used to denote similar components, wherein:
[0018] Figure 1 An illustrative exploded perspective view of the housing assembly for a temperature and humidity detection device disclosed in this application is shown.
[0019] Figure 2 An exemplary cross-sectional schematic diagram of a housing assembly for a temperature and humidity detection device disclosed in this application is shown; and
[0020] Figure 3 An exemplary schematic diagram of the housing assembly for a temperature and humidity detection device disclosed in this application after assembly is shown. Detailed Implementation
[0021] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. First, it should be noted that the directional terms such as up, down, left, right, front, back, inner, outer, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.
[0022] Figure 1 The structure of a housing assembly for a temperature and humidity detection device disclosed in this application is shown. The housing assembly 100 includes a first housing 110 and a second housing 120, which are capable of being joined together to form a cylindrical mounting cavity 130 filled with potting compound (not shown). Matching concave-convex structures 140 are provided on corresponding mating surfaces of the first housing 110 and the second housing 120, allowing the sides of the first housing 110 and the second housing 120 to interlock in a mutually engaging manner (see reference). Figure 2 This design ensures that during assembly, the first housing 110 and the second housing 120 will not have gaps due to the flatness of the injection molded parts or assembly deviations, thus preventing glue leakage and improving the overall sealing performance of the product. When the first housing 110 and the second housing 120 are joined together, there is a small gap between the joint surfaces of the first housing 110 and the second housing 120 to accommodate the potting compound. This gap is small enough that after the mounting cavity 130 is completely filled with potting compound, any excess potting compound can enter the gap and will not leak outward from the gap between the first housing 110 and the second housing 120 before it solidifies.
[0023] In other preferred embodiments, in conjunction with the above embodiments, the inner wall of the first housing 110 is provided with a first positioning shaft 111, and the inner wall of the second housing 120 is provided with a first positioning groove (not shown) for matching the first positioning shaft 111; furthermore, the inner wall of the second housing 120 is provided with a second positioning shaft, and the inner wall of the first housing 110 is provided with a second positioning groove 112 for matching the second positioning shaft (not shown). Further, the first positioning shaft 111 and the second positioning groove 112 are integrally formed with the first housing 110, and the second positioning shaft and the first positioning groove are integrally formed with the second housing 120. Moreover, the first positioning shaft 111 and the second positioning shaft are the same size and shape, and the first positioning groove and the second positioning groove 112 are the same size and shape.
[0024] Those skilled in the art will readily understand that the cross-sectional shape of the gap between the corresponding mating surfaces of the first housing 110 and the second housing 120 is one or more of the following: Z-shaped, V-shaped, bow-shaped, and S-shaped.
[0025] Continue to refer to Figure 1 and Figure 3 To seal the head ends of the first housing 110 and the second housing 120, the housing assembly 100 further includes a plug 150, which has an opening 151. Specifically, the plug 150 includes a first mounting portion 152 and a second mounting portion 153, which are respectively fixed to the head ends of the first housing 110 and the second housing 120 by snap-fit.
[0026] For cost-saving purposes, the first housing 110 and the second housing 120 are the same size and shape. For example, both the first housing 110 and the second housing 120 are injection molded parts for ease of manufacturing.
[0027] In the above embodiments, the inner walls of both the first housing 110 and the second housing 120 are provided with protrusions 160 for preventing incorrect assembly. The number, size, and shape of the protrusions 160 are not specifically limited here.
[0028] Additionally, this application also provides a temperature and humidity detection device, which includes the aforementioned housing assembly 100. The temperature and humidity detection device includes a generally rectangular printed circuit board 10, wherein at least a portion of the printed circuit board 10 is housed within the cylindrical mounting cavity 130, and a sensing unit 11 for detecting temperature and humidity information of the environment under test is provided at one end of the printed circuit board 10. Figure 3As shown, one end of the printed circuit board 10, where the sensing unit 11 is located, extends outward from inside the first housing 110 and the second housing 120 through the opening 151 of the plug 150. The printed circuit board 10 is provided with through holes 12 for the first positioning shaft 111 and the second positioning shaft to pass through.
[0029] In summary, the housing assembly for the temperature and humidity detection device of this application has a simple structure and is easy to install. It can ensure that the glue can be smoothly vented under tension, avoiding insufficient glue filling caused by air cavities, and ensuring that there is no glue leakage at the front end and sides of the housing. It can also effectively install and position the printed circuit board inside the housing.
[0030] The foregoing has provided several specific embodiments to illustrate in detail the housing assembly and the temperature and humidity detection device of this application. These examples are for illustrative purposes only, and are not intended to limit the scope of this application. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of this application. Therefore, all equivalent technical solutions should fall within the scope of this application and be defined by the claims of this application.
