Description

Technical Field

[0001] The utility model relates to the technical field of gallium nitride chargers, in particular to a gallium nitride charger. Background Art

[0002] Gallium nitride material is an important semiconductor material for the development of microelectronic devices. It has the characteristics of wide band gap and high thermal conductivity. It can be used in chargers to adapt to small transformers and high-power devices, and has high charging efficiency. Compared with ordinary semiconductor silicon materials, gallium nitride has a wider band gap and better thermal conductivity, and can match smaller transformers and high-power inductors. Therefore, gallium nitride chargers have the advantages of small size, high efficiency, and greater safety.

[0003] The gallium nitride charger is equipped with multiple USB ports to facilitate the use of multiple USB charging cables. However, when multiple USB charging cables are actually used, the wires are often pulled, causing the joints to loosen. In particular, when the USB connector and the USB plug lose their firmness after long-term use, the loose connector will directly affect the normal charging work. At the same time, when the USB port is not in use, dust is easily collected inside, affecting the normal use of the USB port.

[0004] So we proposed a gallium nitride charger to solve the problems mentioned above. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The purpose of the utility model is to provide a gallium nitride charger to solve the current market problems raised by the above background technology.

[0007] 2. Technical solution:

[0008] To achieve the above object, the utility model provides the following technical solutions: a gallium nitride charger, comprising a gallium nitride charger body, a power plug is installed at the lower end of the gallium nitride charger body, and a plurality of USB interfaces are opened at the upper end of the gallium nitride charger body, and two sets of dust and anti-drop modules are arranged on the outer side of each USB interface;

[0009] The dust and anti-detachment module consists of a guide member, a dust cover clamp assembly and a pressing member. The guide member is used to guide the movement of the dust cover clamp assembly. The pressing member is movably sleeved on the outside of the guide member. The pressing member is used to limit the dust cover clamp assembly.

[0010] Furthermore, anti-slip strips are fixed at equal intervals on the left and right sides of the gallium nitride charger body.

[0011] The above technical solution makes it easy to plug and unplug the gallium nitride charger body.

[0012] Furthermore, the guide member is composed of an integrated fixing plate and two fixing rods, and the fixing plate and the fixing rods are both fixed to the upper end of the gallium nitride charger body.

[0013] The above technical solution makes it easier to move and guide the dust cover clamp assembly.

[0014] Furthermore, the dust cover clamp assembly includes a dust cover body slidably mounted on the outside of the fixing rod, the inner wall of the dust cover body is fixed with a convex strip, and the convex strip is attached to the side inner wall of the fixing plate, and a rubber pad is fixed on the side of the dust cover body close to the center of the USB interface.

[0015] Through the above technical solution, the space sealing can be improved under the action of the rubber pad, and the wear on the USB charging connector can be reduced.

[0016] Furthermore, the front and rear outer walls of the dust cover body are both fixed with convex seats, and a pressure spring is connected and fixed between the convex seats installed on the left and right dust cover bodies.

[0017] Through the above technical solution, the two dust cover bodies can be driven to move relative to each other under the elastic action of the pressure spring.

[0018] Furthermore, the clamping part includes a movable plate sleeved on the outside of two fixed rods, a rotating cylinder is rotatably sleeved inside the rear end of the movable plate, and the rotating cylinder is threadedly sleeved on the outside of one of the fixed rods, and the inner wall of the movable plate is in contact with the outer wall of the other fixed rod.

[0019] Through the above technical solution, after the rotating drum is rotated, the movable plate can be driven to be pressed tightly against the outer wall of the dustproof cover body, thereby achieving the effect of preventing the USB charging connector from falling off.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the gallium nitride charger of the utility model adopts the technical solution provided by the utility model, and realizes the anti-falling effect of the USB charging connector through the cooperation of the dustproof cover and the pressing piece, thereby ensuring normal charging. At the same time, the cooperation of the two dustproof covers is used to realize dustproof treatment, thereby preventing the dust from falling and affecting the use. The specific contents are as follows:

[0022] () When the USB charging connector needs to be inserted into the USB interface, the two dust cover bodies are pulled apart to expose the USB interface, and then the USB charging connector can be inserted into the USB interface, and then the dust cover body is loosened. Under the elastic action of the pressure spring, the dust cover body fits on the side wall of the USB charging connector, and then the rotating drum is rotated. The threaded connection between the rotating drum and the fixed rod, as well as the fitting action of the movable plate and the fixed rod, drive the movable plate to press tightly against the outer wall of the dust cover body, so that the dust cover body is pressed tightly against the outer wall of the USB charging connector, thereby achieving the anti-falling effect of the USB charging connector and ensuring normal charging;

[0023] () When the USB interface is not in use, under the elastic action of the pressure spring, the rubber pads installed on the two dustproof covers fit tightly, so that the USB interface forms a relatively closed space. The USB interface is not easy to collect dust and affect subsequent use. At the same time, the anti-slip strip 4 is arranged on the outer wall of the gallium nitride charger body 1 to facilitate the plugging and unplugging of the gallium nitride charger body 1.
