Description
Technical Field
[0001] This utility model relates to the field of waterproof modular power supply technology, and in particular to a waterproof and sealed modular power supply packaging device. Background Technology
[0002] Modular power supplies are components in electronic devices used to convert input electrical energy into specific voltage and current forms suitable for various parts of the electronic device. They have the advantages of small size, high efficiency, and high reliability, and are used in many fields such as communications, computers, industrial control, and medical equipment. In these application scenarios, the stable operation of modular power supplies is crucial for the normal operation of the entire electronic device.
[0003] Waterproof sealing module power encapsulation device is a protective structural component designed specifically for power modules. It mainly achieves physical protection, stable electrical performance, and waterproof, moisture-proof, dustproof, and corrosion-proof functions for power modules through special materials, processes, and structural design, ensuring that power modules can operate safely and reliably in harsh environments such as humidity, dust, and oil.
[0004] In high and low temperature alternating environments, condensation will occur inside the casing of the waterproof sealed module power packaging device. Even if the seal is intact, short circuits can still occur due to high humidity. Existing technology prevents internal condensation by reserving vent holes on the surface of the casing and installing waterproof and breathable valves to balance the internal and external air pressure. However, after long-term use, the sealing ring and sealing strip will age due to mechanical stress, resulting in a decrease in sealing performance. Utility Model Content

The sealant is injected from the injection port and flows into the glue tank to form a flexible sealing layer. At the same time, the wire harness is embedded in the slot for arrangement and clamping, which restricts the lateral displacement of the wire harness. When the device shakes, the buffer pad absorbs the vibration energy through elastic deformation. This achieves multiple sealing protection at the interface between the outer shell and the wire harness, effectively preventing moisture and dust from entering from the interface gaps, ensuring the safety of the internal environment of the module power supply, and improving the reliability and durability of the module power supply operation.

Buffer pads 4063 are fixedly connected to the bottom of the inner side of each of the multiple slots 602. The buffer pads 4063 prevent the wire harnesses from being worn when the device shakes. The outer wall of the pipe 402 penetrates the left side of the outer wall of the lower shell 1. The bottom end of the pipe 402 is connected to the top of the inner side of the glue tank 404, so that the sealant can be smoothly injected into the glue tank 404 for sealing.
[0039] Specifically, the mounting block 3072 is used to install the positioning hole 3073, providing an installation base for the positioning hole 3073 and ensuring the stability of the positioning structure. The positioning hole 3073 cooperates with the positioning pin 3071 to ensure the lower shell 1 and the upper cover 2 are installed and aligned, enhancing the accuracy during the installation process. The clamping block 4061 can clamp and arrange multiple wire harnesses. The slot 602 places the wire harness in it for fixation, preventing the wire harness from shifting and improving stability. The buffer pad 4063 prevents the wire harness from wearing when the device shakes, extending the service life of the wire harness. The right end of the outer wall of the pipe 402 penetrates the left side of the outer wall of the lower shell 1.

[0040] Working principle: When the device is working, firstly, the positioning pin 3071 in the positioning component 307 cooperates with the positioning hole 3073 to accurately position the lower shell 1 and the upper cover 2. The mounting block 3072 provides the mounting base for the positioning hole 3073. Then, the screw 301 cooperates with the threaded hole 302 to fix the upper cover 2 and the lower shell 1 together to form a complete sealed space. Then, by rotating the adjusting nut 303, the clamping force of the sealing ring 3061 can be precisely controlled. The elastic plate 304 adjusts the pre-tightening force of the sealing ring 3061 through deformation. The spring 305 provides elastic support to keep the upper cover 2 and the lower shell 1 sealed. The sealing groove 3062 is used to install the sealing ring 3061 to ensure its stable position. The sealing ring 3061 in the sealing component 306 prevents external moisture and dust from entering the device and ensures the normal operation of the module power supply.
[0041] Furthermore, the device is installed on other equipment through the mounting hole 4062 and the connector. The pipe 402 is connected to the inner top of the glue tank 404. The sealant is injected through the glue injection port 401, so that the sealant is smoothly injected into the glue tank 404 to achieve effective sealing at the interface between the outer shell and the wire harness. The wire harness is installed in the slot 602. The clamping block 4061 arranges and fixes multiple wire harnesses to prevent the wire harness from shifting.
