Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically a novel power adapter. Background Technology

[0002] With the upgrading of consumer electronics, the demand for fast charging for electronic devices such as laptops has surged, and three-prong plug adapters have become the mainstream choice for users due to their practicality and durability. However, existing power adapters with three-prong plugs have drawbacks such as large size, inconvenience in carrying, high transportation or storage costs, and unstable connections. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of power adapter. This utility model, through its three-prong foldable design, can solve the problems of large size, inconvenience in carrying, and unstable connection of existing power adapters.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel power adapter includes a main body and a PCB power board disposed within the main body, as well as multiple pins and a pin bracket assembly for mounting the pins. The pin bracket assembly includes a support, a rotating component, and conductive springs. The rotating component includes a pivot for mounting the pins, a bushing for limiting the position of the pins, and a connector for linking the multiple pins. The outer wall of the bushing has a contact portion that contacts the conductive springs, and the conductive springs are electrically connected to the PCB power board. The inner wall of the support has a rotating groove for accommodating the bushing, and the surface of the support has a storage groove communicating with the rotating groove.

[0006] Furthermore, it also includes a pressure plate, which is used to limit the conductive spring sheet. The pressure plate is fastened to the bracket on both sides and pressed against the surface of the conductive spring sheet in the middle.

[0007] Furthermore, the inner wall of the bracket is provided with a positioning post, and both the pressure plate and the conductive spring are provided with positioning holes corresponding to the positioning post. The pressure plate limits the conductive spring by cooperating with the positioning post through the positioning hole.

[0008] Furthermore, the pressure plate has mounting holes on both sides, and the inner wall of the bracket has mounting posts corresponding to the mounting holes. The pressure plate is fastened to the mounting posts by screws passing through the mounting holes.

[0009] Furthermore, there are three prongs, each mounted on one of three rotating shafts, which are respectively mounted inside three bushings. There are two connectors, each hinged to two adjacent rotating shafts, so that the three prongs move in unison when unfolded or retracted. The inner wall of the bracket has three rotating grooves, and the three bushings are respectively mounted inside the three rotating grooves. The surface of the bracket has three storage grooves that communicate with each of the three rotating grooves. When retracted, the three prongs are folded into their respective storage grooves.

[0010] Furthermore, the pins are arranged in a triangular pattern, with the storage slot corresponding to the middle pin located in the lower region and the storage slots corresponding to the pins on both sides located in the upper region.

[0011] Furthermore, each connector is provided with two through holes, one upper and one lower. The pivot corresponding to the pin in the middle position is simultaneously hinged to the upper through holes of the two connectors, and the pivots corresponding to the pins on both sides are respectively hinged to the lower through holes of the two connectors.

[0012] Furthermore, the bushing can rotate up and down within the rotating groove, with a maximum rotation angle of 90 degrees.

[0013] Furthermore, the bracket is provided with a slot, and the main body is provided with a buckle that mates with the slot. The main body and the bracket assembly are detachably connected through the engagement of the slot and the buckle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model adopts a three-pronged foldable design, which can reduce the size of the product. When not in use, the user can rotate and fold it into the storage slot, making it easy to carry, transport and store.

[0016] 2. Each pin of this utility model is installed in the rotating groove of the bracket through a rotating shaft and a bushing. The rotating groove limits the rotation angle of the bushing, so that each pin can only rotate a maximum of 90 degrees. This allows the pin to be locked in the storage groove when folded and stored, and stops when unfolded to the vertical plugging angle, preventing excessive rotation and damage. This ensures stable storage and use, and improves the durability of the product.

[0017] 3. The pressure plate of this utility model is fixed on both sides and the bracket, and the conductive spring is fixed in the middle. The structural fit during installation can limit the displacement of the pressure plate and also limit the position of the conductive spring, so as to avoid the spring from shifting and affecting the contact with the grounding part, ensuring stable electrical connection and improving product safety.

The three pins are respectively mounted on three rotating shafts 201, which are respectively mounted inside three bushings 202. The inner wall of the bracket 10 is provided with three rotating grooves 104, and the three bushings 202 are installed one in each of the three rotating grooves 104. The bushings 202 can move within the rotating grooves 104. The bracket 10 has three storage slots 105 that are connected to the three rotating slots. The storage slot corresponding to the third pin 103 is located in the area below it, and the storage slots corresponding to the first pin 101 and the second pin 102 are located in the area above them. In the storage state, the third pin 103 is folded into the storage slot 105 in the area below it, and the first pin 101 and the second pin 102 are folded into the storage slot 105 in the area above it, so that this utility model is easy to carry, transport and store.
