Description
Technical Field
[0001] This invention relates to the field of waterproof electronic products technology, and more particularly to an electrical assembly housing. Background Technology
[0002] Waterproof digital electronic consumer products are gaining increasing market share, with waterproofing of input / output interfaces being of paramount importance. Interfaces typically feature removable sealing covers, but during assembly, compressed gas can easily cause these covers to pop open, leading to assembly failure or difficulty in achieving the correct positioning.
[0003] In existing technologies, to address this issue, an opening is designed into the housing, and a waterproof and breathable membrane is added at the opening. Gas can flow from the high-pressure side to the low-pressure side through the waterproof and breathable membrane, achieving pressure balance between the two sealed spaces and preventing the sealing cover from being ejected by gas. During assembly, the space between the sealing cover and the housing gradually decreases, and some gas is compressed. At this time, some gas enters the electrical sealing space inside the housing through the waterproof and breathable membrane. The degree of gas compression between the sealing cover and the housing decreases, and the gas is only slightly compressed, with insufficient rebound force to make the sealing cover pop open. However, the addition of the waterproof and breathable membrane increases both material and assembly costs. Moreover, the electrical sealing space inside the housing, due to the reserved space for balancing air pressure, results in a larger internal gas volume. The thermal expansion and contraction of the gas also increases the impact on the electrical components, still presenting factors detrimental to assembly stability, affecting the assembly effect and the service life of the electrical components. Summary of the Invention
[0004] The purpose of this invention is to provide an electrical assembly housing that ensures that gas is not compressed during assembly, avoids assembly failure or incomplete assembly, guarantees the stability and sealing of the assembly, and extends the service life of the electrical appliance.

The first sealing part is configured to selectively interfere with and seal against the groove wall of the assembly groove. The first sealing part is provided with an exhaust hole. The cover is provided with a second sealing part, which is located on the inner periphery of the exhaust hole. When the first sealing part abuts against the bottom of the assembly groove, the second sealing part seals against the top of the raised groove.
[0009] As a preferred technical solution for the electrical assembly housing, the outer wall of the raised groove is set at a preset angle to the extension direction of the central axis of the raised groove. The first sealing part is provided with a filling part, the bottom surface of the filling part selectively abuts against the bottom of the assembly groove, the filling part is provided with a mating surface, the mating surface is fitted onto the outer wall of the raised groove, the mating surface is provided with a mating angle, and the mating angle is not less than the preset angle.
[0010] As a preferred technical solution for the electrical assembly housing, the filling part is provided with a sealing edge. When the first sealing part abuts against the bottom of the assembly groove, the sealing edge seals against the inner wall of the transmission hole.
[0011] As a preferred technical solution for the electrical assembly housing, the cover includes an outer cover, which is fixedly connected to the first sealing part. The outer cover is provided with an exhaust port, which is connected to the exhaust hole.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0032] like Figures 1 to 3 As shown, this invention discloses an electrical assembly housing, including a detachable main housing 1 and a cover 2. The main housing 1 has a sealed installation space 11 inside for placing and protecting electronic components. Placing the electronic components in a stable, sealed space can prevent them from being corroded or compressed by external gases or liquids. The main housing 1 is provided with an assembly groove 12, the bottom of which is provided with a transmission port 121 for transmitting electrical signals to the electronic components, allowing for the insertion of external power cords. When the transmission port 121 is not in use, the cover 2 is used to seal the assembly groove 12, protecting the transmission port 121 from dust and water, thereby protecting the installation space 11. A first sealing part 21 is provided on the outer periphery of the cover 2. The first sealing part 21 is press-fitted and sealed with the groove wall of the assembly groove 12, ensuring the installation stability and sealing performance of the cover 2 and the main housing 1. To prevent compressed gas from being generated during the assembly of the cover 2, which might affect the assembly effect, an additional vent 211 is provided on the first sealing part 21, and a second sealing part 22 is provided on the inner circumference of the vent 211. At the same time, a raised groove 122 is provided at the bottom of the assembly groove 12, and the raised groove 122 communicates with the vent 211. When the cover 2 and the main shell 1 begin to assemble, the first sealing part 21 forms a seal with the groove wall of the assembly groove 12. The first sealing part 21 continues to gradually approach the bottom of the assembly groove 12, and the gas between the cover 2 and the main shell 1 is gradually discharged through the vent 211. Until the first sealing part 21 abuts against the bottom of the assembly groove 12, most of the gas can be discharged. At this time, the second sealing part 22 can just abut against the top of the raised groove 122 to form a seal, completing the assembly of the main shell 1 and the cover 2, and further ensuring the sealing performance and assembly effect of the electrical assembly shell, protecting the safety and service life of electronic components.
[0033] Specifically, the outer wall of the raised groove 122 is set at a preset angle to the extension direction of the central axis of the raised groove 122, and the preset angle can be zero degrees; when the preset angle is greater than zero degrees, the outer wall of the raised groove 122 is inclined towards the center of the raised groove 122. In order to further reduce the gas volume inside the electrical assembly housing, the first sealing part 21 is provided with a filling part 212 to fill the excess space between the cover 2 and the main housing 1; when the cover 2 and the main housing 1 are assembled, the bottom surface of the filling part 212 should abut against the bottom of the assembly groove 12 as much as possible to enhance the support effect and sealing performance of the cover 2. A mating surface 2121 is provided on the filling part 212. The mating surface 2121 is the side of the filling part 212 that is closest to and fits onto the outer wall of the protrusion groove 122. The mating surface 2121 is provided with a mating angle, which is not less than a preset angle. This can prevent the cover 2 from sealing with the protrusion groove 122 in advance, which would cause the exhaust hole 211 to be blocked and block the gas from being discharged. This ensures that the gas retention volume is as small as possible, and the sealing is completed at the same time as the assembly is in place, so as to discharge as much gas as possible.
[0034] Furthermore, the filling part 212 can seal the transmission hole. A sealing edge 2122 is provided on the filling part 212. When the first sealing part 21 abuts against the bottom of the assembly groove 12, the sealing edge 2122 seals against the inner wall of the transmission hole at the same time as the cover 2 is assembled. Multiple seals can better protect the sealing performance of the transmission port 121 when it is not in use and keep the electronic devices in the installation space 11 from being disturbed.
[0035] In this embodiment, the cover 2 is a two-color sealing cover. The cover 2 includes an outer cover 23, which can be fixedly connected to the first sealing part 21. The outer cover 23 is provided with an exhaust port 231, which is connected to the exhaust port 211. During the assembly process, the gas gradually discharged is discharged through the exhaust port 211 and the exhaust port 231 in sequence. In order to achieve good sealing performance, the first sealing part 21 and the others are made of a flexible material with good compressibility and resilience; while the outer shell is made of a relatively hard material, which improves the strength and support performance of the cover 2.
[0036] Preferably, the exhaust port 231 is set according to a preset inner diameter, which is smaller than the outer diameter of the exhaust port 211. It is best to set the end of the exhaust port 231 away from the exhaust port 211 to be as small as possible while maintaining ventilation. This helps to prevent dust or liquid from flowing back or blocking and affecting the air flow performance of the exhaust port 211, and avoids the accumulation of excess impurities in the exhaust port 231, which would affect the performance and cleanliness of the cover 2.
[0037] Optionally, the main housing 1 includes an inner cover 13 and an outer peripheral housing 14. The inner cover 13 and the outer peripheral housing 14 are movably connected to selectively seal the installation space 11, allowing personnel to easily open the installation space 11 to replace or repair the electronic components installed inside. The inner cover 13 and the outer peripheral housing 14 form an assembly groove 12 outside the installation space 11. Specifically, the inner cover 13 serves as the bottom of the assembly groove 12, and the inner wall of the outer peripheral housing 14 outside the installation space 11 serves as the wall of the assembly groove 12. The transmission port 121 is located on the inner cover 13. The cover 2 is selectively and sealingly installed inside the assembly groove 12 to seal the transmission port 121, providing a more stable sealing environment for the electrical assembly housing.
[0038] In this embodiment, the inner cover 13 is provided with an assembly seal 15 on its outer periphery. The assembly seal 15 is interference-fitted and sealed with the inner wall of the outer periphery shell 14, which can prevent the inner cover 13 from falling off. When using the transmission port 121, the cover 2 needs to be opened and the external power cord is plugged into the transmission port 121. At this time, the assembly seal 15 plays a role in assisting the sealing connection between the inner cover 13 and the outer periphery shell 14, further enhancing the structural stability of the installation space 11.
[0039] Specifically, the cover 2 is provided with a mating part 232, which can selectively abut against the top of the assembly groove 12. The outer periphery of the mating part 232 is aligned with the outer edge of the outer shell 14, ensuring that the outer surface of the electrical mounting shell is smooth and flat after assembly, avoiding sharp edges that could cut workers, and giving the electrical mounting shell a good aesthetic appearance. Furthermore, the mating part 232 is provided with a handle groove on the outer side near the top of the assembly groove 12. The edges of the handle groove are all rounded, allowing workers to easily and simply remove the cover 2 from the electrical mounting shell by applying force through the handle groove.
[0040] For example, the electrical assembly housing may also be provided with an external connector, one end of which is connected to the cover 2 and the other end of which is connected to the main housing 1. The external connector can keep the cover 2 and the main housing 1 connected together when they are disassembled, so that the cover 2 will not be lost.
[0041] Specifically, such as Figure 4 As shown, the bottom of the assembly slot 12 is provided with a receiving slot 123, and the electrical assembly shell is provided with an inner connector 3. One end of the inner connector 3 is connected to the cover 2, and the other end of the inner connector 3 can be placed in the receiving slot 123. The inner connector 3 is slidably connected to the receiving slot 123. When the main shell 1 and the cover 2 are fully assembled, the inner connector 3 is completely stored in the receiving slot 123, without occupying extra space and with a neat appearance. When the cover 2 is opened, the inner connector 3 can be gradually pulled out from the receiving slot 123 as the cover 2 moves away from the main shell 1. For example, the inner connector 3 is made of flexible material. When the cover 2 is opened, the inner connector 3 can bend so that the cover 2 connected to it avoids the operation position of the operator plugging and unplugging external power cords. Preferably, the inner connector 3 is provided with a limiting part 31. The size of the limiting part 31 is larger than the size of the slot opening of the receiving slot 123, so that the inner connector 3 will not detach from the main shell 1, ensuring the stability of the installation.
[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
