[0038] The installation position is a fixed position for installing electronic components, and the number of installation positions is multiple.

[0039] Each installation position comprises a fixing body 5, a clamping plate 3 is installed on the fixing body 5, the clamping plate 3 can fix the electronic component on the fixing body 5, and multiple clamping plates 3 of the same installation layer are connected with a main plate 4, the main plate 4 can drive the same multiple clamping plates 3 to move synchronously.

[0040] The rear cavity 102 is fixed with a drying box 12, the drying box 12 is communicated with the air inlet of the air blowing device 11, the drying box 12 is connected with the tail part of the cabinet body 1, the drying box 12 in the rear cavity 102 is communicated with the air inlet of the air blowing device 11, the drying agent (such as silica gel) in the drying box 12 absorbs the moisture in the air, so that the air entering the air blowing device 11 maintains low humidity, and then is sent into the front cavity 101 through the air duct. The humidity of the air entering the front cavity 101 is reduced to prevent the electronic components from being short-circuited or corroded due to damp; the drying box 12 is connected with the tail part of the cabinet body 1, so that the drying agent can be replaced, and the drying effect is maintained; in cooperation with the air blowing device 11, the moisture-proof effect is realized while the heat is dissipated, and the service life of the components is prolonged.

[0041] The connector 10 is installed in the rear cavity 102, multiple wire conduits 6 are respectively connected with the external power supply through the connector 10, the connector 10 in the rear cavity 102 serves as an intermediate adapter, the cables led out by the multiple wire conduits 6 are connected to the external power supply through the connector 10, and the unified docking of multiple components and external circuits is realized. The connector 10 simplifies the external wiring process, avoids the confusion of direct docking of cables, facilitates line identification and fault troubleshooting, improves wiring reliability, reduces the risk of poor contact, and improves the safety protection level by isolating the direct connection between internal components and external power supply.

[0042] The inside of the inclined groove of the fixing body 5 is provided with a plug, the plug supplies power to the electronic component, the plug in the inclined groove of the fixing body 5 is adapted to the interface of the electronic component, when the component is placed in the inclined groove and fixed, the plug automatically contacts the component to realize the transmission of electric energy or signal.

[0043] Ventilation openings are provided on both sides of the cabinet 1, and water-retaining strips 9 are fixed on the ventilation openings. Covers are installed at the front cavity 101 and rear cavity 102 of the cabinet 1.

[0044] Example 2

[0045] like Figures 1-7 As shown, based on Embodiment 1, this embodiment provides a power supply method for electronic components, as detailed below:

[0046] The interior of the fixing body 5 is provided with an inclined groove for fixing electronic components. The bottom of the inclined groove is inclined towards the front cavity 101. After the electronic components are placed in the inclined groove, they are naturally limited by the inclined angle and further fixed with the clamping plate 3 to prevent the components from loosening. The inclined groove structure uses gravity to assist in fixing the electronic components, reducing the stress load on the clamping plate 3. The inclination towards the front cavity 101 makes it easier to observe and operate the components from the front cavity 101, improving maintenance convenience. It also enhances the stability of component installation, making it especially suitable for vibration environments.

Cables of electronic components are led out or connected to the rear cavity 102 through the conduit 6, achieving cable isolation between the front cavity 101 (component area) and the rear cavity 102 (wiring area). The centralized management of cables through the conduit 6 avoids cable clutter in the front cavity 101 and reduces the risk of short circuits. Unified wiring in the rear cavity 102 facilitates line inspection and maintenance, reducing interference with components in the front cavity 101. The conduit 6 provides physical protection against cable wear and external environmental influences.

[0048] Example 3

[0049] like Figures 1-7 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a method for disassembling electronic components, as detailed below:

[0050] The card plate 3 is slidably installed inside the motherboard 4 via the first elastic body 7. The top of the electronic component is provided with a card strip that is compatible with the card plate 3. The card plate 3 is provided with a card slot that is compatible with the card strip. The card plate 3 is slidably installed on the motherboard 4 via the first elastic body 7. The card strip on the top of the electronic component is compatible with the card slot of the card plate 3. The elasticity of the elastic body makes the card plate 3 tightly engage with the card strip, thereby fixing the component. When disassembling, the card plate 3 can be loosened by overcoming the elasticity with external force.

[0051] The elastic clamping structure realizes quick mounting and dismounting of the electronic component without tools, improves maintenance efficiency; the first elastic body 7 can buffer vibration to avoid loosening of the component due to impact; the adaptive design of the clamping groove and the clamping strip ensures accurate installation position of the component and prevents misplacement.

[0052] The partition plate 2 is internally provided with a sliding groove adapted to the main plate 4, the main plate 4 is slidably installed in the interior of the sliding groove through the second elastic body 8, the main plate 4 is slidably installed in the sliding groove of the partition plate 2 through the second elastic body 8, the elastic force of the elastic body keeps the main plate 4 driving the clamping plate 3 to always maintain the compression force on the electronic component; when it is necessary to adjust the position of the component, the main plate 4 can be slid by external force compressing the elastic body. The second elastic body 8 provides continuous compression force, enhances the fixing effect of the clamping plate 3 on the component, and adapts to the installation requirements of components of different sizes; the sliding groove guides the main plate 4 to move stably, ensures the consistency of synchronous action of multiple clamping plates 3; the elastic buffering function reduces the influence of vibration of the cabinet 1 on the component, and improves the overall stability.

[0053] The bottom of the front cavity 101 is fixed with a blowing device 11, the air outlet of the blowing device 11 opens upward, the air inlet of the blowing device 11 extends into the rear cavity 102, the air outlet of the blowing device 11 at the bottom of the front cavity 101 opens upward, the air inlet extends into the rear cavity 102, and during operation, air is sucked from the rear cavity 102 and blown to the top of the front cavity 101, forming an airflow from bottom to top, which carries away the heat generated by the electronic components in the front cavity 101. Forced air cooling circulation accelerates heat dissipation of the front cavity 101, avoids aging or failure of the components due to high temperature, and the air suction of the rear cavity 102 can use the relatively stable ambient air (such as air treated by drying) in the rear cavity 102 to improve the heat dissipation efficiency; the upward air outlet conforms to the law of hot air rising, optimizing the heat dissipation path.

[0054] Working principle:

[0055] The cabinet 1 is divided into a front cavity 101 (component installation area) and a rear cavity 102 (wiring and auxiliary function area) by a partition plate 2, realizing physical isolation of component installation and wiring. The multiple installation layers of the front cavity 101 integrate electronic components through multiple installation sites, and the rear cavity 102 concentrates on processing wiring, drying, and auxiliary functions such as ventilation, forming a collaborative system of "installation-wiring-protection".

[0056] The electronic component is initially positioned by the inclined slot of the fixing body 5 (the front inclination of the bottom of the inclined slot utilizes gravity to assist in limiting), and then is fixed by the clamping strip on the top of the component and the clamping plate 3; the clamping plate 3 is connected with the main plate 4 through the first elastic body 7, and the main plate 4 is installed in the sliding groove of the partition plate 2 through the second elastic body 8, which not only ensures the stable compression of the clamping plate 3 on the component, but also realizes the synchronous movement of multiple clamping plates 3 by pushing the main plate 4, facilitating batch mounting and dismounting or position adjustment of the components. At the same time, the latch in the inclined slot automatically interfaces with the component interface, completing power or signal transmission.

[0057] The drying box 12 of the rear cavity 102 adsorbs the moisture in the air by desiccant, and sends the low-humidity air into the front cavity 101 through the air blowing device 11; the air circulation is formed by the air vents on both sides of the cabinet body 1 in cooperation with the air blowing device 11, so that the heat dissipation and the low-humidity environment are maintained at the same time. The water baffle 9 of the air vent and the cover plate of the front and rear cavities 102 block the external rainwater, moisture and foreign matters from invading, so as to ensure the stability of the internal environment.

[0058] The cable of the element in the front cavity 101 is inserted into the rear cavity 102 through the wire pipe 6 at the back of the fixing body 5, and is connected with the external power supply after being concentrated and converted by the connector 10, so as to realize the orderly wiring of "element-wire pipe 6-connector 10-external power supply"; the plug-in pin in the inclined groove automatically supplies power after the element is fixed, so as to simplify the wiring process.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present application can still be modified or replaced equivalently without departing from the spirit and scope of the present application, and any modification or partial replacement should be covered in the scope of the claims of the present application.
