The socket has a socket, and the plug has a conductive pin that can be inserted into the socket. The socket is installed on a wall or ceiling, and small light appliances such as chandeliers and ceiling fans are electrically connected to the plug. The plug and the socket are assembled together.

[0003] CN01823877.7 discloses a combination of a fixable socket and a plug rotatable therein, which is used to conduct electricity and mechanically support a device receiving the electricity in a desired direction, the combination comprising: a) a socket rigidly mounted to a wall or ceiling, the socket comprising a non-conductive body, the non-conductive body comprising at least two spaced-apart hollow arched conductive sockets, the sockets being insulated from each other and having a common center of curvature and connected to a power source, the socket rigidly supporting a first member of a mechanical connection located at the center of curvature; b) a plug, also comprising a non-conductive body, the rigidity of which The invention relates to a plug that is mounted to the device and is arranged to mechanically support the device from a first surface, the plug supporting at least two protruding mutually insulated conductive pin elements from a second surface, the pins being engageable with the at least two arcuate sockets respectively and connectable to conductors to power the device, the plug including a second member that is engageable with the first member of the mechanical connection and allows the plug to at least partially rotate about the center of curvature; and c) a releasable locking device that is mounted to the combination and, when engaged, provides a retention force between the socket and the plug to prevent separation and support the device. The locking device 46 includes a split expandable column end 48 with a shoulder 50. The push rod 52 with a shoulder inside moves axially to expand the split end 48 so that the shoulder 50 abuts against the hole of the first member 34. This locking device is configured to have the column end capable of cracking and expanding. When axially inserting, the cracked column end needs to be squeezed inwards first. After being inserted into place, the column end will not be squeezed and will expand outwards to achieve the shoulder and the hole of the first component to achieve installation and fixation. However, this structure is not easy to disengage the two; and the cracked column end will not have a good supporting and fixing effect after multiple squeezing and deformation. In another locking device structure, when the ball 72 protrudes outwards, the ball 72 holds the plug 66 in the socket 64; the rod 74 is pushed inwards to make it lean against the compression spring 76, so as to allow the ball 72 to retreat into the recess 78 and remove the plug 66.

The plug 2 and the socket 1 are respectively provided with a hook A31 and a slot A32 for the hook head end A311 on the hook A31 to axially enter and exit. The slot A32 is arranged in an arc shape or has a larger opening, which can facilitate the inner circumferential rotation of the hook A31. After the hook head end A311 on the hook A31 passes through the slot A32, the plug 2 is rotated circumferentially in the locking direction, which will make the hook head end A311 of the hook A31 relatively rotated and can directly or indirectly hook the limiting surface A33 located on one circumferential side of the slot A32, thereby forming an axial locking of the plug 2 and the socket 1. The socket 11 is arranged in an arc shape or has a larger opening, which can facilitate the inner circumferential rotation of the pin 21. Specifically, the limiting surface A33 is integrally provided with a convex plate 34, and the hook end A311 has a locking protrusion 311a that can hook the convex plate 34. The locking protrusion 311a is hooked on the outside of the convex plate 34, which has a certain limiting effect on the circumferential rotation of the hook A31 in the unlocking direction. The mating contact surfaces C of the convex plate 34 and the locking protrusion 311a are both arc surfaces, which facilitates the locking protrusion 311a to pass through the convex plate 34 so that the two are locked.

[0031] Specifically, the pin 21 and the hook A31 are provided on the top of the plug 2; the jack 11 and the hook A32 are provided on the bottom of the socket 1, and a movable concave area 1a that can accommodate the top of the plug 2 to move inside is provided, and the plug 2 can rotate in the movable concave area 1a, and the limit surface A33 is located on the upper surface of the bottom of the socket. A detachable base plate 1b is provided on the bottom of the socket shell, the jack 11 and the hook A32 are both located on the base plate 1b, and the limit surface A33 is located on the upper surface of the base plate 1b, the base plate 1b is connected to the bottom of the socket shell by a snap-fit ​​connection, and of course the base plate 1b can also be provided as an integral part of the base plate.

The plug core 12 is set away from the jack 11 in the circumferential direction. The side of the plug pin 21 has a protruding plug part 21a. After the plug part 21a on the plug pin 21 passes through the jack 11, the plug part 21a rotates circumferentially in the locking direction through the plug 2 and is inserted into the plug core 12 on one side. The plug pin 21 is an arc-shaped piece and has a "7"-shaped structure.

[0034] The working principle of this utility model:

[0035] When installing the plug 2, the plug 2 is mounted upward on the socket 1. After the hook end A311 on the hook A31 passes through the bayonet hole A32 upward, the plug 2 is rotated circumferentially in the locking direction, driving the hook A31 to rotate synchronously. The hook end A311 of the hook A31 will rotate circumferentially and deviate from the bayonet hole A32. The locking protrusion 311a is hooked on the outer side of the protruding plate 34 located on one side of the bayonet hole A32, which has a certain limiting effect on the circumferential rotation of the hook A31 in the unlocking direction. The plug 2 is restricted from rotating in the unlocking direction, and the axial locking of the plug 2 and the socket 1 is also formed to prevent the plug 2 from being separated from the socket 1 downward.

[0036] The jack 11 can accommodate the pin 21 to rotate in the inner circumferential direction. After the plug 2 is rotated in the locking direction, the plug portion 21a of the pin 21 will be inserted into the plug core 12 on one side to contact and conduct electricity.

[0037] When the plug 2 is removed, the plug 2 is manually rotated circumferentially in the unlocking direction, which will cause the latch 311a to deform and disengage from the convex plate 34, and the hook end A of the latch A will rotate back to the corresponding latch port A, while the plug portion 21a of the pin 21 rotates out of the plug core 12 and is set corresponding to the socket 11. At this time, the latch A31 can pass downward through the latch port A32, and the pin 21 can pass downward through the socket 11, and the plug 2 can be removed from the socket 1.

[0038] The utility model realizes unlocking / locking by rotating the plug, which is convenient for the disassembly and assembly of the plug and the socket, and the disassembly and assembly is fast.

A hook B51 and a bayonet B52 for axial entry and exit of a hook head end B511 on the hook B51 are respectively provided on the outer cover 4 and the socket 1. The bayonet B52 is arranged in an arc shape or has a larger opening, and can also facilitate the inner circumferential rotation of the hook B51. After the hook head end B511 on the hook B51 passes through the bayonet B52, the outer cover 4 is rotated circumferentially in the locking direction, which will make the hook head end B511 directly or indirectly hook the limiting surface B53 located on one side of the bayonet B52 after relative rotation, thereby constituting axial locking of the outer cover 4 and the socket 1. When the hook end B511 on the hook B51 is protruding inward, the bayonet B52 has an entry and exit hole 521 and a locking hole 522 extending circumferentially from the entry and exit hole 521. The hook end B511 is restricted from axially disengaging from the locking hole 522, and the plug hole B521 can allow the hook end B511 to axially enter and exit. After the hook end B511 on the hook B51 passes through the entry and exit hole 521, rotating the plug 2 circumferentially in the locking direction will make the hook B51 turn from the entry and exit hole 521 into the locking hole 522, and the hook end B511 will directly or indirectly hook the limiting surface B53 located on the side of the locking hole 522, thereby forming an axial locking of the outer cover 4 and the socket 1; of course, after the hook B rotates in the bayonet B, its hook end B can directly or indirectly hook the limiting surface B located on one side of the bayonet B in the circumferential direction. Specifically, the hook B51 is integrally arranged at the upper end of the cover wall of the outer cover 4, and the bayonet B52 is located at the edge of the socket; of course, the bayonet B52 can also be arranged on the outer cover 4, and the hook B51 is integrally arranged at the edge of the socket. The outer cover 4 can cover the plug 2 to improve the appearance; and the outer cover 4 has a simple installation structure, and unlocking / locking is achieved by rotating the outer cover 4, which facilitates the assembly and disassembly of the outer cover 4 and the socket 1, and the assembly and disassembly is fast. When the outer cover 4 is installed, the outer cover 4 is mounted upward on the socket 1, and after the hook head end B511 on the hook B51 passes upward through the inlet and outlet hole B521 in the bayonet B, the outer cover 4 is rotated circumferentially in the locking direction, so that the hook B51 is rotated from the inlet and outlet hole B521 into the lock hole B522, and the hook head end B511 directly or indirectly hooks the limit surface B53 located on the side of the lock hole B522, thereby forming an axial lock between the outer cover 4 and the socket 1, and preventing the outer cover 4 from being separated downward from the socket 1; when the outer cover 4 is removed, the outer cover 4 is manually rotated circumferentially in the unlocking direction, and the hook head end B511 of the hook B51 will relatively rotate back and leave the limit surface B53, and the hook head end B511 can pass downward through the inlet and outlet hole 521, so that the outer cover 4 can be removed from the socket 1. Of course, the outer cover can also be threadedly connected to the socket, or the outer cover and the socket can be slidably connected.
