Description

Technical Field

[0001] The present application relates to the technical field of power supply housings, for example, to a USB power supply housing with a new IP44 protection grade. Background Art

[0002] With the increasing prevalence of electronic devices, the demand for convenient and efficient charging continues to grow. Early power supplies often lacked protection, making them difficult to operate reliably in complex environments. To meet charging needs in dusty and water-prone environments, USB power supplies with an IP44 rating were developed.

[0003] Traditional USB power supply shells all use a simple assembly structure, and the assembly method is the buckle form. The direct buckle method will easily allow dust particles to enter the buckle gap, causing safety risks. At the same time, the waterproof performance is poor, affecting the quality. Utility Model Content

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] The disclosed embodiment provides a USB power supply housing with a new IP44 protection level to solve the problem of poor waterproof effect and easy intrusion of dust.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A new IP44 protection grade USB power shell, including an upper cover, a shell, and a sealing ring. The upper cover is buckled with one end of the shell, a waterproof USB is provided in the shell, and a sealing ring is provided between the waterproof USB and the upper cover. A lower edge ring is provided on the bottom side of the upper cover, and a plug-in groove is provided on the inner side of the shell end corresponding to the lower edge ring. The lower edge ring is inserted into the plug-in groove. The arrangement of the lower edge ring and the plug-in groove can ensure the stability and sealing of the buckling between the upper cover and the shell, and ensure that dust and water on the shell will not penetrate into the shell through the gap and affect the product quality. The shell and the upper cover are made of waterproof and corrosion-resistant PC945 material. The lower edge ring is inserted into the plug-in groove to minimize the shell. The gap between the upper cover and the shell can be filled with ultrasonic welding design after the upper cover is buckled with the shell to ensure a tight connection. The waterproof USB end fixing sleeve is provided with a sealing ring, and one side of the sealing ring contacts the inner side of the upper cover. The waterproof USB adopts high-quality waterproof terminals, which cooperate with the sealing ring to ensure a tight fit between the waterproof USB and the upper cover, further preventing the intrusion of moisture. The buckling method of the upper cover and the shell and the setting of the sealing ring can ensure the waterproof function. When the USB power supply is in a humid environment or exposed to water for a long time, it can achieve moisture-proof and water-avoiding effects, avoid damage to the power supply as much as possible, and prevent dust particles from entering the shell, further avoiding safety hazards such as short circuit and overload.

[0008] Furthermore, a through hole is provided at a position of the upper cover corresponding to the waterproof USB socket, and the USB power cord can be conveniently plugged in through the through hole.

[0009] Furthermore, a circuit board is provided inside the shell, and the circuit board is fixedly connected to the waterproof USB.

[0010] Furthermore, a pin is provided at the end of the shell, and the pin passes through the shell in a sealed manner and is connected to the circuit board, and is connected to the power supply through the pin.

[0011] The present disclosure provides a new IP44 protection grade USB power supply housing, which can achieve the following technical effects:

[0012] 1): The lower edge ring of the utility model is inserted into the plug-in slot. The arrangement of the lower edge ring and the plug-in slot can ensure the stability and sealing of the buckle connection between the upper cover and the shell, ensuring that dust and water on the shell will not penetrate into the shell through the gap and affect the product quality;

[0013] 2): In the utility model, the waterproof USB end fixing sleeve is provided with a sealing ring, one side of which contacts the inner side of the upper cover. The waterproof USB adopts high-quality waterproof terminals, which cooperate with the sealing ring to ensure a tight fit between the waterproof USB and the upper cover. The buckle connection between the upper cover and the shell and the setting of the sealing ring can ensure the waterproof function. When the USB power supply is in a humid environment or exposed to water for a long time, it can achieve moisture-proof and water-avoiding effects, avoiding damage to the power supply as much as possible.

[0021] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0022] A new IP44 protection grade USB power shell, including an upper cover 1, a shell 2, and a sealing ring 4. The upper cover 1 is buckled with one end of the shell 2, and a waterproof USB 3 is provided in the shell 2. A sealing ring 4 is provided between the waterproof USB 3 and the upper cover 1. A lower edge ring 12 is provided on the bottom side of the upper cover 1, and a plug-in groove 21 is provided on the inner side of the end of the shell 2 corresponding to the lower edge ring 12. The lower edge ring 12 is inserted into the plug-in groove 21. The arrangement of the lower edge ring 12 and the plug-in groove 21 can ensure the stability and sealing of the buckling between the upper cover 1 and the shell 2, and ensure that dust and water contaminated on the shell 2 will not penetrate into the shell 2 through the gap, affecting the product quality. The material of the shell 2 and the upper cover 1 is made of waterproof and corrosion-resistant PC945 material. The form of inserting the lower edge ring 12 into the plug-in groove 21 reduces the gap between the shell 2 and the upper cover 1 as much as possible. After the upper cover 1 is buckled with the shell 2, an ultrasonic welding design can be adopted to ensure a tight connection.

[0023] The waterproof USB3 end fixing sleeve is provided with a sealing ring 4, one side of the sealing ring 4 contacts the inner side of the upper cover 1, and the waterproof USB3 adopts a high-quality waterproof terminal, which cooperates with the sealing ring 4 to ensure a tight fit between the waterproof USB3 and the upper cover 1, further preventing the intrusion of moisture. The upper cover 1 is provided with a through hole 11 at the position corresponding to the waterproof USB3 jack, and the USB power cord is conveniently plugged in through the through hole 11. The buckling method between the upper cover 1 and the shell 2 and the setting of the sealing ring 4 can ensure the waterproof function. When the USB power supply is in a humid environment or exposed to water for a long time, it can achieve moisture-proof and water-proof effects, and avoid damage to the power supply as much as possible. At the same time, it can also prevent dust particles from entering the inside of the shell 2, further avoiding safety hazards such as short circuit and overload.
