AI Technical Summary
Existing multi-functional power converters lack effective interlocking mechanisms, leading to pin misoperation and safety hazards, affecting stability and user experience.
Design a multi-functional power converter that uses anti-single-plug accessories and a retractable plug structure to achieve plug interlock control. Safety protection components and a self-resetting temperature control fuse are installed inside the housing to ensure that the plug extends independently and prevent accidental plugging and accidental contact.
It effectively avoids interference and mis-insertion between pins, improves the safety and operational standardization of the power converter, and enhances user experience and equipment protection performance.

Abstract
Claims
1. A multi-functional power converter, characterized by, include: A housing (1) having at least three types of pins provided on it; The anti-single insertion accessory (9) is installed inside the housing (1) and located at the positions of at least three types of pins. When one type of pin extends outside the housing (1), the remaining pins are locked by the anti-single insertion accessory (9). A bracket (10) is disposed inside the housing (1), and a circuit board (11) is mounted on the bracket (10). The circuit board (11) is also provided with multiple adapters (7). At least three types of pins include British standard pins (2), American and Australian multi-purpose pins (5) and European standard pins (4). The European standard pins (4) are set in a groove (3) opened on the housing (1). A first limiting groove (41) is provided on one side of the European standard pins (4) and a second limiting groove is provided on the other side. The British standard pin (2) and the American / Australian multi-purpose pin (5) are telescopically arranged on both sides of the housing (1). The outer end of the British standard pin (2) is provided with a first actuating block, and the outer end of the American / Australian multi-purpose pin (5) is provided with a second actuating block (6). When the British standard pin (2), the American / Australian multi-purpose pin (5) and the European standard pin (4) are all retracted into the housing (1), the anti-single-pin accessory (9) is located in the center position. At this time, the anti-single-pin accessory (9) does not lock any pin. The anti-single-pin accessory (9) includes a first main body (91) and a second main body (92). The first main body (91) and the second main body (92) are movably assembled. Positioning posts (97) are provided on the opposite surfaces of the two. A support spring (99) is provided between the two positioning posts (97). A first limiting part (98) is provided on the side of the body part (91) away from the second main body part (92), and a second limiting part (93) is provided on the side of the second main body part (92) away from the first main body part (91). The first limiting part (98) is used to limit the British standard pin (2), and the second limiting part (93) is used to limit the American and Australian multi-purpose pin (5). The bottom surfaces of the first limiting part (98) and the second limiting part (93) are both inclined guide surfaces. A first locking part (96) is provided on the first main body part (91), and a second locking part (94) is provided on the second main body part (92) corresponding to the first locking part (96). The first locking part (96) is located on one side of the first limiting groove (41), and the second locking part (94) is located on one side of the second limiting groove.
2. The multi-functional power converter of claim 1, wherein: The circuit board (11) is provided with a first elastic conductive contact for each type of pin, and a second elastic conductive contact is provided for each type of pin corresponding to the first conductive contact.
3. The multi-functional power converter of claim 1, wherein: A universal socket (12) is provided on the side of the housing (1) away from the circuit board (11). A safety guard (8) is movably provided on the universal socket (12) to block part of the socket on the universal socket (12).
4. The multi-functional power converter of claim 1, wherein: A self-resetting temperature control fuse (20) is also provided inside the housing (1) on one side of the circuit board (11), and the self-resetting temperature control fuse (20) is electrically connected to the circuit board (11).
5. The multi-functional power converter of claim 1, wherein: The second main body (92) is provided with a limiting groove (95), and the housing (1) is provided with a limiting slider at the position corresponding to the limiting groove (95). The limiting slider slides into the limiting groove (95).
