Abstract
Description
Technical Field
[0001] This invention relates to rail sockets in electrical components, and more specifically to a power adapter and a rail socket having the same. Background Technology
[0002] As living standards improve, people need to use more and more electrical appliances, thus requiring a greater number of wall sockets. Ordinary wall sockets are often insufficient, while installing too many can be aesthetically displeasing. Therefore, track sockets have emerged as a solution.
[0003] A track socket includes an adapter and a long, narrow track. The track is mounted on the wall, and the track socket is electrically connected to the wall power supply line. The adapter has a conductive plate and a socket. When using the track socket, the conductive plate of the adapter is inserted into the track slot and contacts the track socket. Then, the plug of the appliance is inserted into the socket of the adapter, and the appliance draws power from the adapter. For example, an adapter disclosed on the Chinese Patent Network, publication number CN203386996 U, draws power by rotating after being inserted into the power track. Because it is impossible to determine which direction to rotate after inserting the adapter into the power track, it is very inconvenient and not user-friendly. It also has drawbacks such as excessive rotation, leading to easy damage to the adapter and a short service life. Summary of the Invention
[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention aims to provide a power adapter that can be directly powered by inserting into the power rail without the need for rotation or separate switch operation, making it more convenient and simple to use.

[0008] Preferably, the base of the present invention is provided with an outwardly extending guide rod in the middle. One end of the guide rod is integrally formed with the base, and the other end protrudes through the through hole of the closed end. A conductive plate passes through the inside of the guide rod and protrudes through the through hole.
[0009] Preferably, the conductive plates of the present invention are L-polar conductive plates, N-polar conductive plates and E-polar conductive plates. One end of the L-polar conductive plates, N-polar conductive plates and E-polar conductive plates are electrically connected to the PCB circuit board, the other end of the L-polar conductive plates and N-polar conductive plates are electrically connected to one end of the corresponding conductive sheet, and the other end of the E-polar conductive plate passes through one end face of the guide box and touches the conductor copper rod in the power rail.
[0010] Preferably, the adapter body of the present invention includes a housing, a top cover, and a decorative panel. The cavity is disposed on the housing and is fastened by a cover plate. A guide box at the other end away from the limiting plate passes through the cover plate, so that one end of the guide box slides in the cavity through the limiting plate. A magnetic component is fixed to the bottom of the housing, and a PCB circuit board is fixed inside the housing. The PCB circuit board is provided with multiple plug terminals, and the top cover is provided with the same number of plug terminals.

[0012] Preferably, the fulcrum of the present invention is fixed to the guide box by means of a fixed shaft or a support rod.
[0013] Preferably, the guide box of the present invention is further provided with a limiting platform for supporting the conductive sheet below the opening, and the limiting platform is fixed on the guide box.

[0015] Preferably, the present invention also includes a track socket comprising the power adapter described in any one of the above descriptions.
[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects:

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0038] One example of this embodiment is a power adapter, such as... Figures 1 to 9As shown, the adapter includes an adapter body 1. A guide box 2, which can be inserted into a power rail, is located on the back of the adapter body 1. A cavity 10 is provided on the adapter body 1. One end of the guide box 2 is placed inside the cavity 10 via a limiting plate 15 to prevent it from detaching from the cavity 10. The guide box 2 has two conductive plates and a base 4 that drives the conductive plates to rotate around a fulcrum and draw power from the power rail 3. The base 4 is fixedly connected to one end of the conductive plates. The guide box 2 has an opening 20 at the position of the conductive plates, allowing the conductive plates to flip outwards. The opening 20 communicates with the interior of the guide box 2. The two conductive plates are an L-polar conductive plate 21 and an N-polar conductive plate 22. The base 4 slides relative to the guide box 2 within the cavity, thereby simultaneously driving the L-polar conductive plate 21 and the N-polar conductive plate 22 to rotate outwards around their corresponding fulcrums. The fulcrum can be any one of a fixed shaft or a support rod. In this invention, a fixed shaft 5 is used. Support structures 23, capable of rotating around a fulcrum, are provided on both the L-polar conductive sheet 21 and the N-polar conductive sheet 22. The support structures 23 use shaft holes or open slots. For ease of installation and production, the support structures of this invention use open slots. The L-polar conductive sheet 21 and the N-polar conductive sheet 22 are respectively secured to the corresponding fixed shaft 5 through the open slots. The fixed shaft 5 is installed and fixed on the guide box 2. Because the guide box 2 has an opening 20, the L-polar conductive sheet 21 and the N-polar conductive sheet 22 rotate outward around the corresponding fixed shaft 5. A limiting platform 24 is also provided below the opening of the guide box 2. The limiting platform 24 is fixed on the guide box 2 and can be integrally injection molded with the guide box 2. The limiting platform 24 mainly serves to support the guide sheets. The adapter body 1 is provided with a magnetic component 19 capable of attracting the power rail 3. The magnetic component 19 is a magnet.
[0039] The adapter body 1 includes a housing 11, a top cover 12, and a decorative panel 13. A cavity 10 is disposed on the housing and is fastened by a cover plate 14. The cover plate 14 is fixed to the housing 11 by screws. A guide box 2, located away from the limiting plate 15, passes through the cover plate 14, allowing one end of the guide box 2 to slide within the cavity 10 via the limiting plate 15. A PCB circuit board 16 is disposed inside the housing 11, and multiple plug terminals 17 are disposed on the PCB circuit board 16. The top cover has the same number of plug holes 18 as the plug terminals. A magnet is disposed inside the housing 11, and the adapter is fixed to the power rail 3 by the magnet. Of course, a metal plate 30 is embedded in the panel of the power rail 3 to achieve the fixing effect.
[0040] The guide box 2 and the base 4 are made of insulating material. The guide box 2 has a hollow structure with one open end and the other closed end. The closed end has a through hole 25. The guide box 2 is inserted into the base 4 through the open end and can slide. The base 4 has an outwardly extending guide rod 40 in the middle. One end of the guide rod 40 is integrally formed with the base 4, and the other end passes through the through hole 25 of the closed end. A conductive plate is fixed on the base 4. The conductive plate can be directly injection molded with the base mold during production, and the conductive plate is wrapped inside the base 4. Of course, the conductive plate can also be fixed after injection molding through the base 4. The conductive plates are L-polar conductive plate 6, N-polar conductive plate 7 and E-polar conductive plate 8. One end of the L-polar conductive plate 6, N-polar conductive plate 7 and E-polar conductive plate 8 are electrically connected to the PCB circuit board 16. The E-polar conductive plate 8 passes through the inside of the guide rod 40, and its other end passes through the through hole and can touch the conductor copper rod in the power rail.
[0041] For the safety of the adapter, the E-pole conductive plate 8 is positioned at the vertical insertion point into the power rail, while the L-pole conductive plate 6 and N-pole conductive plate 7 are located at the upper and lower ends of the power rail 3. Of course, the positions of the L-pole conductive plate 6, N-pole conductive plate 7, and E-pole conductive plate 8 are adjustable and there is no fixed position. As long as they can touch the corresponding conductor copper rod of the power rail to draw power, it is acceptable.
[0042] To ensure the conductive sheet can reset when the adapter is pulled out of the power rail, an elastic element 9 is provided between the inner wall of the guide box 2 and one end of the base 4. A spring coil is preferably used as the elastic element 9. One end of the spring coil is fixed to the base 4, and the other end is positioned on the inner wall of the guide box 2. A spring positioning rod 26 can be added inside the guide box 2. The spring positioning rod 26 can be set on the end face of the limiting platform 24. The other end of the spring coil is sleeved on the spring positioning rod 26, serving as a guide for pushing and resetting. The guide box 2, the limiting platform 24, and the spring positioning rod 26 are integrally injection molded. Of course, the present invention can also achieve adapter removal without adding the elastic element 9 between the inner wall of the guide box 2 and the base 4; the conductive sheet will simply need to be manually reset, without affecting the normal operation of the adapter.
[0043] The present invention also includes a track socket comprising a power track 3 and a power adapter 30 as described above.
[0044] In the embodiment of this application, the power rail 3 can be installed on a wall or desktop surface. The conductor copper rods inside the power rail 3 contact the corresponding conductive sheet and the E-pole conductive plate to draw power from the corresponding power supply line. Specifically, the conductor copper rods inside the power rail 3 include an L-pole conductor copper rod 31, an N-pole conductor copper rod 32, and an E-pole conductor copper rod 33, with the L-pole conductor copper rod 31 and the N-pole conductor copper rod 32 arranged opposite each other.
[0045] When using the track socket for power supply, the adapter 30 is inserted into the track groove 34 of the power track 3. After insertion, the E-polar conductive plate 8 touches the E-polar conductor copper rod 33. As the adapter body 1 continues to be pressed into the track groove 34, one end of the guide box 2 can slide in the cavity 10. The base 4 will drive the L-polar conductive plate 6 and the N-polar conductive plate 7 to rotate around the opening of the fixed shaft 5, so that one end of the L-polar conductive plate 6 and the N-polar conductive plate 7 respectively touches and electrically connects with the corresponding L-polar conductor copper rod 31 and N-polar conductor copper rod 32 to draw power. The adapter body 1 is also magnetically fixed to the panel of the power track 3, so the adapter will not fall off. The operation is simpler and more user-friendly.
[0046] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
