Abstract
Claims
1. A retractable plug mechanism for a power converter, comprising a housing, a top cover fitted onto the housing, and a retractable plug movably disposed within the housing and the top cover, the retractable plug comprising a socket body movably disposed within the housing, a plug assembly disposed within the socket body, and an operating mechanism disposed on the plug assembly and slidably disposed on the socket body, the plug assembly comprising a shared slide seat movably disposed on the socket body, and at least two sets of pins disposed on the shared slide seat. The socket body is provided with a standard socket hole through which the plug prong extends out of the socket body; a shell-mounted operating groove is formed on the side of the housing, extending through one end toward the standard socket hole and allowing the operating mechanism to slide into it; a socket-mounted operating groove is formed on the socket body, allowing the operating mechanism to slide into it; the shell-mounted operating groove and the socket-mounted operating groove are on the same vertical axis and overlap vertically; after the operating mechanism slides out of the housing along the shell-mounted operating groove, it continues to slide on the socket body along the socket-mounted operating groove.
2. The plug extension mechanism for a power converter as described in claim 1, wherein, The operating mechanism includes a push handle disposed on the shared slide and protruding from the housing at its upper end, and a first reset member disposed between the push handle and the shared slide.
3. The plug extension mechanism for a power converter as described in claim 2, wherein, The operating mechanism further includes a limiting and fixing member disposed on the socket body, a socket limiting member movably disposed on the limiting and fixing member, and a second resetting member disposed between the socket limiting member and the limiting and fixing member.
4. The plug extension mechanism for a power converter as described in claim 3, wherein, The end of the operating groove on the shell facing the top cover has a first locking position extending to both sides, and the end of the operating groove on the shell away from the top cover has a second locking position extending to both sides.
5. The plug extension mechanism for a power converter as described in claim 4, wherein, A sleeve limiting plate is formed on the sleeve limiting member. When stored, the sleeve limiting plate is inserted into the first locking position. When pushed out for use, the push handle is pressed to push the sleeve limiting plate away from the first locking position and push it out of the housing along the lower direction of the operating through groove on the housing until the sleeve limiting plate is placed into the second locking position.
6. The plug extension mechanism for a power converter as described in claim 1, wherein, At least one insert limiting block is formed on the side of the insert body, which protrudes to the side and prevents the insert body from coming out of the housing.
7. The plug extension mechanism for a power converter as described in claim 6, wherein, The housing has at least one insert limiting guide rail for sliding of the insert limiting block.
8. The plug extension mechanism for a power converter as described in any one of claims 2 to 4, wherein, The inner wall of the insert body is provided with a second slide rail that is located on the side of the insert operating slide groove and parallel to the insert operating slide groove. A third locking position is formed at the end of the second slide rail facing the upper cover, and a fourth locking position is formed at the end of the second slide rail away from the upper cover.
9. The plug extension mechanism for a power converter as described in claim 8, wherein, The shared slide block has a second slide groove that matches the second slide rail.
10. The plug extension mechanism for a power converter as described in claim 9, wherein, The push handle is provided with a plug clip plate. When stored, the plug clip plate is inserted into the third slot. When pushed out for use, the push handle is pressed, the first reset member is compressed and deformed, and the plug clip plate is pressed out of the third slot. At the same time, the second slide rail is placed in the second slide groove and pushed out of the housing along the second slide rail until the plug clip plate is placed into the fourth slot.
11. The plug extension mechanism for a power converter as described in any one of claims 3 to 5, wherein, The insert body is provided with at least one limiting and fixing hole, and the limiting and fixing member is formed with at least one limiting and fixing block that is engaged in the limiting and fixing hole.
12. The plug extension mechanism for a power converter as described in any one of claims 3 to 5, wherein, The insert limiting member has at least one insert limiting push rod extending outward, and the shared slide has at least one insert limiting sliding hole for the insert limiting push rod to slide.
13. The plug extension mechanism for a power converter as described in claim 12, wherein, The insert limiting push rod is slidably inserted into the insert limiting sliding hole and can move relative to the shared slide block between an extended position and a retracted position.
14. The plug extension mechanism for a power converter as described in claim 12, wherein, The insert limiting push rod is clearance-fitted with the insert limiting sliding hole, and the insert limiting push rod can move radially within the insert limiting sliding hole.
15. A plug extension mechanism for a power converter as described in any one of claims 3 to 5, wherein, The insert limiting member is provided with insert limiting sliders that protrude toward both sides respectively, and the limiting fixing member is provided with insert limiting grooves for the insert limiting sliders to slide up and down.
16. A plug extension mechanism for a power converter as described in any one of claims 2 to 5, wherein, The shared slide has first operating limit blocks that extend upward and limit the two ends of the push handle at both ends.
17. A plug extension mechanism for a power converter as described in any one of claims 2 to 5, wherein, The lower end of the push handle is formed with at least one downwardly protruding second operating limit block, and the shared slide is formed with at least one second operating clearance hole that matches the second operating limit block.
18. The plug extension mechanism for a power converter as described in claim 1, wherein, The plug assembly is a European standard plug assembly.
19. The plug extension mechanism for a power converter as described in claim 3, wherein, The inner wall of the housing is provided with a first slide rail that is located on the side of the control slot on the housing and parallel to the control slot on the housing.
20. The plug extension mechanism for a power converter as described in claim 19, wherein, The first slide rail has a fifth locking position at the end facing the top cover, and a sixth locking position at the end away from the top cover.
21. The plug extension mechanism for a power converter as described in claim 20, wherein, The socket body has at least one first groove that matches the first slide rail.
22. The plug extension mechanism for a power converter as described in claim 21, wherein, A sleeve limiting plate is formed on the sleeve limiting member. When stored, the sleeve limiting plate is inserted into the fifth locking position. When pushed out for use, the push handle is pressed to push the sleeve limiting plate away from the fifth locking position. The first slide rail is placed into the first slide groove and pushed out of the housing along the first slide groove until the sleeve limiting plate is placed into the sixth locking position.
23. The plug extension mechanism for a power converter as described in claim 19, wherein, An ejector guide slope is formed on the end of the first slide rail facing the top cover.
24. The plug extension mechanism for a power converter as described in claim 3, wherein, A third slide rail is provided on the inner wall of the upper cover, protruding toward the housing. The third slide rail is perpendicular to the upper cover and is located on the side below the operating groove on the housing after the upper cover is closed on the housing.
25. The plug extension mechanism for a power converter as described in claim 24, wherein, The third slide rail has a seventh locking position at the end facing the top cover, and an eighth locking position at the end away from the top cover.
