Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to an electronic component with moisture-proof function. Background Technology

[0002] Electronic components are the components of electronic parts and small machines and instruments. They are usually composed of several parts and can be used in similar products. They often refer to certain parts in the electrical, radio, and instrument industries. They are a general term for electronic devices such as capacitors, transistors, hairsprings, and clockwork, and commonly include diodes. They are widely used in electronic circuits and perform functions such as energy conversion, signal processing, and circuit control.

[0003] The existing patent (publication number: CN217445661U) discloses that "this utility model relates to the field of electronic components, and in particular to an electronic component with moisture-proof function, including a main control circuit board. A capacitor, resistor, transistor, and potentiometer are soldered to the top of the main control circuit board. A protective shell is fitted onto the outer ring of the main control circuit board, and a shock-absorbing plate is installed on the top of the protective shell via a shock-absorbing mechanism. A groove is formed inside the main control circuit board. This utility model, through the provision of a groove, a first fixing plate, a sealing gasket, a threaded rod, and a hexagonal nut, allows the protective shell and the groove to fit tightly together via the sealing gasket. By rotating the hexagonal nut, the first fixing plate is tightened downwards, and the hexagonal nut is positioned above the first fixing plate. The four hexagonal nuts work simultaneously, ensuring that the protective shell is stably secured to the main control circuit board, achieving a sealing and waterproof effect. The sealing gasket is stable, wear-resistant, high-temperature resistant, and has a long lifespan. The protective shell has anti-corrosion properties, and the aluminum material has good heat dissipation, helping the main control circuit board dissipate heat."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: the existing electronic components adopt the installation method of rotating hexagonal nuts. By tightening four hexagonal nuts, the first fixing plate is tightened downwards, and the protective shell is fixed on the main control circuit board. The installation process not only requires repeated adjustment of the tightness of the four nuts, but also requires constant attention to the limiting position of the hexagonal nuts above the first fixing plate. The operation steps are cumbersome and time-consuming.

[0005] Therefore, those skilled in the art have provided an electronic component with moisture-proof function to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electronic component with moisture-proof function. The fixing mechanism, through the cooperation of screws, turntables, connecting columns, connecting plates, fixing blocks, and fixing grooves, can firmly fix the moisture-proof box inside the mounting shell, ensuring the working stability of the moisture-proof box.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An electronic component with moisture-proof function includes a mounting shell and a moisture-proof box. The mounting shell has a fixing mechanism at the front end, the fixing mechanism includes a turntable, and two connecting posts are fixedly provided at the rear end of the turntable. Connecting plates are slidably provided on both sides inside the mounting shell, and the front ends of the two connecting plates are provided with sliding grooves. A screw is fixedly provided at the front end of the turntable.

[0009] The moisture-proof box has multiple fixing slots on both sides, and multiple fixing blocks are fixedly installed at opposite ends of the two connecting plates. A cover plate is hinged to the front end of the moisture-proof box, a breathable mesh is fixedly installed at the upper inside of the moisture-proof box, and a locking block is slidably installed at the front end inside the moisture-proof box.

[0010] Furthermore, the two connecting columns are slidably disposed at the front end of the two sliding grooves respectively, and the screw is externally threaded to the front end of the mounting shell.

[0011] Furthermore, the turntable is externally rotatably disposed inside the front end of the mounting housing, and the plurality of fixing blocks are respectively disposed in pairs opposite each other inside the plurality of fixing slots.

[0012] Furthermore, a spring is fixedly installed at the upper end of the card block, and the upper end of the spring is fixedly installed at the upper front end of the inside of the moisture-proof box.

[0013] Furthermore, the upper end of the cover plate is provided with a slot, and the lower end of the card block is disposed inside the slot.

[0014] Furthermore, a first sealing strip is fixedly provided at the front end of the moisture-proof box, and the front and rear ends of the first sealing strip are respectively disposed between the moisture-proof box and the cover plate.

[0015] Furthermore, a second sealing strip is fixedly provided at the lower end of the interior of the mounting shell, the exterior of the moisture-proof box is provided inside the mounting shell, and the exterior of the second sealing strip is provided between the moisture-proof box and the mounting shell.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes an electronic component with a moisture-proof function. When installing the moisture-proof box, first insert the moisture-proof box into the mounting shell. Then, rotate the screw to make the turntable and connecting column rotate. The connecting column will slide in the slide groove, causing the connecting plate to slide towards each other inside the mounting shell, thereby allowing the fixing block to be embedded in the fixing groove, thus firmly installing the moisture-proof box inside the mounting shell. The whole operation process is relatively simple and quick, while providing a stable fixing effect. In addition, the second sealing strip will be tightly attached between the moisture-proof box and the mounting shell, which can effectively prevent the intrusion of external moisture.

[0018] 2. This utility model proposes an electronic component with a moisture-proof function. When the desiccant is placed inside the moisture-proof box and the cover is closed, the rotation of the cover will cause the locking block to slide upward. After the cover is closed, the spring pushes the locking block to reset, thereby allowing the locking block to be embedded in the slot, thus fixing the cover and the moisture-proof box. The desiccant inside the moisture-proof box can absorb moisture in time when a small amount of moisture enters the moisture-proof box, thereby ensuring that the electronic component is always in a dry environment, effectively improving the moisture-proof ability of the electronic component, extending its service life and ensuring its normal operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-6One embodiment provided by this utility model:

[0029] An electronic component with moisture-proof function includes a mounting shell 1 and a moisture-proof box 2. The mounting shell 1 has a fixing mechanism 3 at the front end. The fixing mechanism 3 includes a turntable 303. Two connecting posts 306 are fixedly installed at the rear end of the turntable 303. Connecting plates 302 are slidably installed on both sides inside the mounting shell 1. The front end of the two connecting plates 302 is provided with a sliding groove 307. A screw 304 is fixedly installed at the front end of the turntable 303.

[0030] Two connecting columns 306 are slidably disposed on the outside of the front end of the two sliding grooves 307, the screw 304 is threadedly connected to the front end of the mounting shell 1, the turntable 303 is rotatably disposed on the outside of the front end of the mounting shell 1, and multiple fixing blocks 305 are disposed on opposite ends of multiple fixing grooves 301.

[0031] Specifically, when protecting the electronic components inside the lower part of the mounting housing 1 from moisture, first precisely align the lower end of the moisture-proof box 2 with the upper opening of the mounting housing 1, apply vertical force to smoothly insert the moisture-proof box 2 into the mounting housing 1, and then rotate the screw 304 clockwise. Due to the threaded connection between the screw 304 and the front end of the mounting housing 1, the rotation of the screw 304 is converted into the rotation of the turntable 303 at the front end inside the mounting housing 1. During the rotation of the turntable 303, the connecting post 306 fixed on its back slides linearly along the groove 307 at the front end of the connecting plate 302. At this time, there is still a certain distance between the turntable 303 and the connecting plate 302, and the depth of the groove 307 is greater than the length of the connecting post 306. The rotation of screw 3 will cause the connecting plates 302 on both sides of the mounting shell 1 to slide synchronously towards each other. When the connecting plate 302 moves into place, the fixing block 305 on the opposite side will be embedded in the fixing groove 301, thereby completing the stable installation of the moisture-proof box 2. At the same time, the second sealing strip 10 at the lower end of the mounting shell 1 will be tightly attached to the bottom of the moisture-proof box 2 and the inner wall of the mounting shell 1 under the pressure, so that the second sealing strip 10 will undergo elastic deformation and fill the gap, thereby improving the moisture-proof performance. Installation and disassembly can be completed with simple operation, which improves the efficiency of daily maintenance, repair and replacement of electronic components and reduces labor costs. Conversely, rotating screw 304 counterclockwise can release the connection between fixing block 305 and fixing groove 301.

[0032] Reference Figures 1-5 The moisture-proof box 2 has multiple fixing slots 301 on both sides, and multiple fixing blocks 305 are fixedly installed on one side of each of the two connecting plates 302. The front end of the moisture-proof box 2 is hinged with a cover plate 4, and the upper part of the inside of the moisture-proof box 2 is fixedly installed with a breathable mesh 5. The front end of the inside of the moisture-proof box 2 is slidably installed with a locking block 7.

[0033] A spring 6 is fixedly installed on the upper end of the locking block 7. The upper end of the spring 6 is fixedly installed on the upper front end of the inside of the moisture-proof box 2. A slot 9 is opened on the upper end of the cover plate 4. The lower end of the locking block 7 is installed inside the slot 9. A first sealing strip 8 is fixedly installed on the front end of the moisture-proof box 2. The front and rear ends of the first sealing strip 8 are respectively installed between the moisture-proof box 2 and the cover plate 4. A second sealing strip 10 is fixedly installed on the lower end of the inside of the mounting shell 1. The outside of the moisture-proof box 2 is installed inside the mounting shell 1. The outside of the second sealing strip 10 is installed between the moisture-proof box 2 and the mounting shell 1.

[0034] Specifically, after installation, by opening the cover plate 4, the desiccant is evenly placed on the ventilated mesh 5 at the upper end of the inside of the moisture-proof box 2. When the cover plate 4 is closed, the rear end of the cover plate 4 contacts the inclined surface of the locking block 7. Under the action of the pushing force, the locking block 7 slides upward inside the moisture-proof box 2, compressing the spring 6. When the cover plate 4 is fully closed, the slot 9 and the locking block 7 are precisely aligned. The spring 6 releases the stored elastic potential energy, pushing the locking block 7 to slide downward inside the moisture-proof box 2, so that its lower end is embedded in the slot 9 of the cover plate 4, achieving a firm lock between the cover plate 4 and the moisture-proof box 2. At this time, the first sealing strip 8... The desiccant is fully compressed and deformed to form a moisture-proof sealing barrier between the cover plate 4 and the moisture-proof box 2. If a small amount of moisture breaks through the external barrier and enters the moisture-proof box 2, the desiccant on the breathable mesh 5 will quickly absorb the moisture and continuously maintain a dry environment inside the box, providing long-term protection for the electronic components at the lower end of the housing 1. The breathable mesh 5 adopts a porous structure, which facilitates the flow of moisture to the desiccant and blocks desiccant particles, ensuring that it can stably perform its moisture absorption function. Desiccant moisture absorption is a mature and publicly available technology. Therefore, its specific structure and working principle will not be described in detail in this article.

[0035] The second sealing strip 10 and the first sealing strip 8 form physical sealing barriers between the mounting shell 1 and the moisture-proof box 2, and between the moisture-proof box 2 and the cover plate 4, respectively. Combined with the breathable mesh 5 and the desiccant, they can effectively resist the corrosion of high humidity environment and reduce the probability of electronic components malfunctioning due to moisture, such as short circuits and oxidation. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Working principle: When the moisture-proof box 2 needs to be installed, align its lower end with the upper end of the mounting shell 1, and then insert the moisture-proof box 2 into the mounting shell 1. Next, rotate the screw 304. Since the screw 304 is threadedly connected to the front end of the mounting shell 1, the rotation of the screw 304 will drive the turntable 303 to rotate at the front end inside the mounting shell 1. When the turntable 303 rotates, its fixed connecting post 306 slides in the sliding groove 307 of the connecting plate 302, so that the two connecting plates 302 slide towards each other on both sides inside the mounting shell 1, thereby allowing the fixing block 305 on the connecting plate 302 to be inserted into the fixing groove 301, so that the moisture-proof box 2 is securely installed inside the mounting shell 1. At this time, the second sealing strip 10 at the lower end of the mounting shell 1 is tightly attached between the moisture-proof box 2 and the mounting shell 1, which can effectively prevent external moisture from entering.

[0037] Next, the desiccant is placed in the breathable mesh 5 inside the moisture-proof box 2. Then, the cover 4 is closed so that its rear end contacts the locking block 7. Since the front end of the locking block 7 is tilted, it will slide upward inside the moisture-proof box 2 and compress the spring 6 connected to it, causing it to contract. When the cover 4 is closed, the spring 6 rebounds, pushing the locking block 7 back to its original position, so that it is embedded in the slot 9 at the upper end of the cover 4, thus fixing the cover 4 to the moisture-proof box 2. At the same time, the rear end of the cover 4 will be tightly pressed against the first sealing strip 8 to achieve a seal and moisture prevention.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
