A power rail socket structure

Abstract

This invention discloses a power rail socket structure, including a power rail, a socket, a plug, and a locking mechanism. The power rail includes a first housing with a power receiving slot, one end of which has an entrance communicating with the power receiving slot. The socket includes a second housing with an opening and a cover plate installed at the opening, the second housing and the cover plate being rotatably connected relative to each other. The plug is disposed on the cover plate and extends into the power receiving slot through the entrance. The locking mechanism has a locked position and an unlocked position. In the locked position, the locking mechanism locks the plug in the power receiving slot, and in the unlocked position, the locking mechanism releases the plug from its locked position in the power receiving slot. When the plug extends into the power receiving slot of the power rail through the entrance, the locking mechanism locks the plug in the power receiving slot, avoiding problems such as poor contact between the plug and the power rail and short circuits, thereby improving the service life of the power rail socket structure and enhancing electrical safety.

[0028] Example 1

[0029] See also Figure 1 and Figure 2 A power rail socket structure 100 includes a power rail 1, a socket 2, a plug 3 and a locking mechanism 4; the power rail 1 includes a first shell 11 having a power extraction slot 10, and an inlet 12 connected to the power extraction slot 10 is formed at one end of the first shell 10; the socket 2 includes a second shell 20 having an opening and a cover plate 21 installed at the opening, and the second shell 20 and the cover plate 21 can be relatively rotatably connected; the plug 3 is arranged on the cover plate 21, and the plug 3 extends from the inlet 12 into the power extraction slot 10.

[0030] The locking mechanism 4 has a locking position and an unlocking position. In the locking position, the locking mechanism 4 locks the plug 3 in the power extraction slot 10, and in the unlocking position, the locking mechanism 4 releases the position lock of the plug 3 in the power extraction slot 10. When in use, when the plug 3 extends from the entrance 12 into the power extraction slot 10 of the power rail 1, the plug 3 is locked in the power extraction slot 10 by the locking mechanism 4, avoiding the problem of poor contact and short circuit between the plug 3 and the power rail 1, thereby improving the service life of the power rail socket structure 100 and improving the safety of electricity use.

[0031] See also Figure 2 and Figure 3 Specifically, the locking mechanism 4 includes a push portion 40, a locking member, and a locking spring 41 disposed on the second housing 20. The push portion 40 rotates with the second housing 20, and the push portion 40 is used to push the locking member to rotate; the locking member is disposed on the cover plate 21, and the locking member includes an execution portion 42 and a locking portion 43. The execution portion 42 and the locking portion 43 are an integrated structure, which ensures the overall strength of the locking member. Among them, the execution portion 42 is configured to be pushed by the push portion 40, and a locking notch 44 is disposed at one end of the insert 3 close to the locking portion 43. The locking portion 43 is locked in the locking notch 44 in the locking position, and the locking portion 43 can be disengaged from the locking notch 44 in the unlocking position; the locking spring 41 is disposed between the execution portion 42 and the cover plate 21, and the locking spring 41 abuts against the execution portion 42. For example, the cover plate 21 of the socket 2 is provided with a rotating shaft 45 , the locking portion 41 is sleeved on the rotating shaft 45 , and the locking portion 41 can rotate around the rotating shaft 45 , and the locking torsion spring 41 is sleeved on the rotating shaft 45 .

[0032] The working principle of the above-mentioned locking mechanism is as follows: when the plug 3 is inserted into the power extraction slot 10 from the entrance 12, the second shell 20 of the socket 2 is rotated, and the pushing part 40 rotates with the second shell 20, and the pushing part 40 pushes the locking piece to rotate, and the locking piece rotates around the rotating shaft 45, and the locking part 43 extends into the locking notch 44, and the locking piece is released. Under the action of the locking spring 41, the locking part 43 is engaged in the locking notch 44 to complete the locking, so that the socket 2 is kept in the power extraction slot 10 of the power rail 1; the pushing part 40 pushes the locking piece to rotate, and the locking piece rotates around the rotating shaft 45, and the locking part 43 is rotated out of the locking notch 44 to complete the unlocking, thereby realizing the separation of the socket 2 and the power rail 1.

[0033] Preferably, an expansion slot 13 is formed at the other end of the first housing 11 , and the expansion slot 13 is configured as an integral mounting structure of the power track socket structure 100 , so that the power track socket structure 100 can be connected and used with other additional accessories. Figure 2The expansion slot 13 shown is a dovetail slot, but it should be understood that this embodiment does not further limit the shape of the expansion slot 13. With this structure, the versatility and flexibility of the power rail socket structure 100 can be improved.

[0034] Preferably, see Figure 4 The power rail socket structure 100 provided in this embodiment further includes a sealing structure 5 installed at the inlet 12 of the first shell 1 , and the sealing structure 5 is used to seal the inlet 12 .

[0035] For example, the sealing structure 5 includes two elastic seals 50, both of which are made of insulating material, and when the plug 3 extends from the inlet 12 into the power extraction slot 10, the plug 3 is clamped between the two elastic seals 50, and the two elastic seals 50 are configured to seal the inlet 12. With this structure, it is possible to prevent moisture or dust from entering the power extraction slot 10 from the inlet 12, thereby achieving a dustproof and waterproof effect.

[0036] The elastic sealing member 50 includes a sealing portion 500 and an embedding portion 501 . The first housing 11 is provided with a card slot 52 , and the embedding portion 501 is accommodated in the card slot 52 .

[0037] The sealing portion 500 is formed with a special-shaped cavity 502. Figure 1 The special-shaped cavity 502 shown is a circular structure. However, it should be understood that the shape of the sealing portion 500 is not limited to a circular structure, and can be a triangular or square structure. Therefore, this embodiment does not further limit the shape of the special-shaped cavity 502. In addition, an elastic filler is provided in the special-shaped cavity 502 to provide a safe and reliable sealing structure with good sealing performance.

[0038] Preferably, the sealing portion 500 is a circular structure. The sealing structure commonly used in the prior art is a sheet-like seal. During the sealing process, there are large gaps between the sheet-like seals, which affects their sealing performance. The present application adopts an elastic seal with the above structure, which solves the problem of poor sealing compared to the sheet-like seal, thereby achieving a good waterproof and dustproof effect.

[0039] The two elastic seals 50 provided in this embodiment are arranged opposite to each other. When in use, the two elastic seals 50 generate a pair of clamping forces on the plug-in 3. Since the elastic seals 50 are elastic structures, when installing the plug-in, the plug-in 3 can be extended into the power extraction slot 10 from the entrance 12 under the elastic action of the two seals. After the plug-in 3 is installed, under the elastic recovery action of the elastic seals 50, the two elastic seals 50 and the plug-in 3 can completely seal the entrance 12.

[0040] In summary, when the plug 3 extends from the entrance 12 into the power extraction slot 10 of the power rail 1, the plug 3 is locked in the power extraction slot 10 by the locking mechanism 4, thereby avoiding the problem of poor contact and short circuit between the plug 3 and the power rail 1, thereby improving the service life of the power rail socket structure 100 and improving the safety of electricity use.
