Abstract
Description
Technical Field
[0001] This utility model relates to the field of charger technology, specifically a small fast charger. Background Technology
[0002] The working principle of a charger is to convert AC mains power (usually 220V AC) into voltage and current suitable for charging electronic device batteries through a power conversion circuit. Small fast chargers generally refer to mobile phone chargers, which consist of a charger plug and a data cable.
[0003] As technology advances, chargers continue to evolve towards miniaturization and portability. However, charger plugs and data cables are generally separate (i.e., the charger plug is inserted into the socket, and the data cable connects the phone to the charger plug; most charger plugs are the same model, but the data cable varies depending on the phone model). This results in the data cable generally not being fixed to the charger (older chargers were fixed, but the fixed settings had low selectivity and adaptability, and older chargers were gradually phased out).
[0004] To achieve portability, charger plugs are becoming smaller and smaller, making them easier to place in pockets. However, since the data cable and charger plug are separate, the data cable inevitably gets tangled together when stored in a pocket, making the pocket messy and easily tangled with keys, lipstick, and mobile phones. When taking items out, it is also easy to pull them out of the pocket, causing unnecessary loss. Therefore, a small fast charger is proposed to solve the above problems. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a small fast charger, which solves the problems mentioned in the background art.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides a small fast charger, including a charger plug and a data cable. One end of the data cable is a USB plug, and the other end is a Type-C plug. The USB plug can be inserted into the USB interface of the charger plug. The charger plug has winding grooves on both sides, which are arranged obliquely and staggered. The charger plug has fitting slots that are adapted to the USB plug and the Type-C plug, respectively. Each fitting slot is equipped with a limiting component. The limiting component includes two limiting pieces made of elastic plastic and a pressing top piece. The pressing top piece is hinged to the charger plug, and the two limiting pieces are fixed to the charger plug. A limiting block is fixed inside the two limiting pieces. After the pressing top piece is pressed into the inside of the two limiting pieces, the limiting block can restrict the pressing top piece from flipping.
[0009] Optionally, the depth of the fitting groove is the same as the thickness of the USB plug and the Type-C plug, and the USB plug and the Type-C plug can be completely embedded in the fitting groove.
[0010] Optionally, both sides of the injection-molded portion of the USB plug and the Type-C plug are fixed with semi-circular retaining beads, and the fitting groove and the pressing top piece are provided with semi-circular bead grooves that are adapted to the semi-circular retaining beads.
[0011] Optionally, the charger plug has winding passages on both sides where there is no winding groove. One end of the winding passage leads from one winding groove to the next winding groove on the other side, and the data cable can be gradually wound in the winding groove and the winding passage in a diagonal spiral.
[0012] Optionally, the winding groove is connected to the two fitting grooves, which are located on two different surfaces of the charger plug.
[0013] Optionally, the depth of the winding groove and the winding passage is the same as the diameter of the cable portion of the data cable. When the cable of the data cable is wound around the charger plug, the cable portion of the data cable is completely placed within the winding groove and the winding passage.
[0014] Optionally, the spacing between the two winding grooves and the two winding passages is equal to the diameter of the cable portion of the data cable.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, the present invention provides a small fast charger with the following advantages:
[0017] 1. This utility model effectively improves the neatness of storage and the convenience of carrying by wrapping the data cable around the charger plug and restricting the plug with a limiting component. It solves the problem that traditional data cables are easy to get tangled with other items in pockets and are easy to take out of the pocket when taking them out, resulting in the loss of items.
[0018] 2. This utility model has semi-circular retaining beads fixed on both sides of the injection-molded part of the USB plug and the Type-C plug, and semi-circular bead grooves adapted to the semi-circular retaining beads are opened in the fitting groove and on the pressing top piece. When the USB plug and the Type-C plug are inserted into the fitting groove, the semi-circular retaining beads can be precisely embedded in the semi-circular bead groove in the fitting groove, which plays a preliminary positioning and fixing role, and ensures that the plug will not easily shake or fall off in the fitting groove.
[0019] 3. By setting two fitting slots on different surfaces of the charger plug and combining the connection design of the winding slot and the fitting slot, the structure of the entire charger is more compact. In a limited space, it can both wind and store the data cable and properly place the plug, avoiding space waste caused by unreasonable structural layout, increasing the number of turns of the data cable, and thus increasing the length of the data cable.

[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] Example: Please refer to Figures 1 to 6 According to an embodiment of this utility model, a technical solution is provided: a small fast charger, including a charger plug 1 and a data cable 2. One end of the data cable 2 is a USB plug 3, and the other end is a Type-C plug 4. The USB plug 3 can be inserted into the USB interface 5 of the charger plug 1. The charger plug 1 has winding grooves 6 on both sides, and the winding grooves 6 on both sides are arranged obliquely and staggered. The charger plug 1 has fitting grooves 7 that are adapted to the USB plug 3 and the Type-C plug 4 respectively. Limiting components are installed on the fitting grooves 7. The limiting components include two limiting pieces 8 made of elastic plastic and a pressing top piece 9. The pressing top piece 9 is hinged to the charger plug 1, and the two limiting pieces 8 are fixed to the charger plug 1. The inner side of the two limiting pieces 8 is fixed with a limiting block 10. After the pressing top piece 9 is pressed into the inner side of the two limiting pieces 8, the limiting block 10 can restrict the pressing top piece 9 from flipping.
[0029] USB plug 3 and Type-C plug 4 are compatible with most electronic devices and mobile phones on the market, making them highly versatile. They can also be configured as other interfaces, depending on the device being used. Other options include Lightning interface and 30-pin Dock interface. It should be noted that the charging power of fast charger plug 1 varies depending on the voltage, current, and other data, as well as the fast charging protocol and the device. It can typically reach a charging power of 18W-22.5W.
[0030] The small fast charger with the above structure has fitting slots 7 on the charger plug 1 that are adapted to the USB plug 3 and the Type-C plug 4 respectively. The USB plug 3 can be inserted first. The top plate 9 is pressed into the inside of the two limiting plates 8 by pressing the top plate 9. The top plate 9 is restricted by the limiting block 10 and cannot be flipped, thus fixing the USB plug 3. Then, the data cable 2 is gradually spiraled diagonally around the charger plug 1 along the winding groove 6. After winding, the other end of the Type-C plug 4 can be pressed into the inside of the two limiting plates 8 by pressing the top plate 9 again to restrict the Type-C plug 4. In this way, the data cable 2 can be wound around the charger plug 1, which is difficult to loosen. It can effectively improve the neatness of storage and the convenience of carrying, and solve the problem that the traditional data cable 2 is easy to get tangled with other items (keys, lipstick, mobile phone, etc.) in the pocket, and the items are easily taken out and lost when taking them out.
[0031] The depth of the fitting groove 7 is the same as the thickness of the USB plug 3 and the Type-C plug 4. The USB plug 3 and the Type-C plug 4 can be completely embedded in the fitting groove 7. This allows the USB plug 3 and the Type-C plug 4 to be completely embedded in the fitting groove 7, which can avoid scratches and collisions caused by direct contact between the plug and other items during daily carrying or storage. It can effectively protect the metal contacts and shell of the plug, extend the service life of the plug, and ensure the stability and conductivity of the connection between the plug and the device.
[0032] Both sides of the injection-molded parts of the USB plug 3 and the Type-C plug 4 are fixed with semi-circular retaining beads 11. The fitting groove 7 and the pressing top plate 9 are both provided with semi-circular bead grooves 12 that are adapted to the semi-circular retaining beads. When the USB plug 3 and the Type-C plug 4 are inserted into the fitting groove 7, the semi-circular retaining beads 11 can be precisely embedded in the semi-circular bead grooves 12 in the fitting groove 7, which plays a preliminary positioning and fixing role. When the pressing top plate 9 is pressed down, the semi-circular bead grooves 12 on the pressing top plate 9 can also fit tightly with the semi-circular retaining beads 11, further enhancing the fixing effect and ensuring that the plug will not easily shake or fall off in the fitting groove 7.
[0033] The charger plug 1 has winding passages 13 on both sides where there is no winding groove 6. One end of the winding passage 13 leads from one winding groove 6 to the next winding groove 6 on the other side, so that the data cable 2 can be gradually wound in the winding groove 6 and the winding passage 13 in a diagonal spiral. When the user needs to store the data cable 2, one end of the data cable 2 is inserted from the beginning of the winding passage 13, and the data cable 2 is guided along the direction of the winding passage 13, so that it naturally transitions from one winding groove 6 to the other winding groove 6. In this process, the data cable 2 will gradually be wound in the winding groove 6 and the winding passage 13 in a diagonal spiral, guiding the user to wind it in a preset manner.
[0034] The winding groove 6 is connected to the two fitting grooves 7, which are located on two different surfaces of the charger plug 1. The connection between the winding groove 6 and the fitting grooves 7 makes the structure of the entire charger more compact. In a limited space, the data cable 2 can be wound and stored, and the plug can be properly placed. This avoids the waste of space caused by unreasonable structural layout, increases the number of turns of the data cable 2, and thus increases the length of the data cable 2.
[0035] The depth of the winding groove 6 and the winding passage 13 is the same as the diameter of the cable portion of the data cable 2. When the cable of the data cable 2 is wrapped around the charger plug 1, the cable portion of the data cable 2 is completely placed inside the winding groove 6 and the winding passage 13, so that the surface of the data cable 2 after wrapping is basically flush with the surface of the charger plug 1, and there will be no cable protrusion. The overall storage is more orderly, and the stability of the charger will not be affected by the cable protrusion. It also makes it easier to store the charger in limited spaces such as bags and pockets, reducing the possibility of the cable protruding and snagging or tangling with other items.
[0036] The spacing between the two winding grooves 6 and the two winding passages 13 is the diameter of the cable portion of the data cable 2, so that the data cable 2 is neither too tight and difficult to operate when winding, nor too loose and occupy too much space, thus improving the efficient use of space.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
