Abstract
Description
Technical Field
[0001] The utility model particularly relates to a power supply track. Background Art
[0002] Track sockets are becoming increasingly popular among consumers, and are poised to gradually replace traditional wall sockets in places like kitchens and offices. In reality, the track socket system consists of two parts, a power track and a track socket, which are used together. The power track is electrically connected to the fixed power wiring, and has a long, strip-shaped slot on its outer surface. When in use, the track socket is inserted into the slot of the matching power track to draw power. Existing power tracks include a track body, an N-pole busbar, an L-pole busbar, and a ground busbar disposed within the track body, and a terminal assembly electrically connected to the N-pole busbar, L-pole busbar, and ground busbar. Existing power tracks use two strips of plastic as protective doors. These protective doors deform after a period of use and cannot be restored, rendering their protective performance ineffective and resulting in low safety. Furthermore, the connection between the terminal blocks and the N-pole busbar, L-pole busbar, and ground busbar is cumbersome, resulting in low assembly efficiency. Summary of the Invention
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a power rail with simple structure, stable and reliable performance, high assembly efficiency, good protection performance and high safety.
[0004] To achieve the above objectives, the present invention employs a power rail comprising a rail body, two insulating strips symmetrically disposed within the rail body, an N-pole busbar and an L-pole busbar, respectively disposed on the two insulating strips, a grounding conductive sheet, a terminal assembly disposed at one end of the rail body, a support seat disposed on the rail body, a plurality of protective doors rotatably disposed on the support seat and covering the strip-shaped slots of the rail body, and a plurality of torsion springs disposed between the plurality of protective doors and the support seat. The terminal assembly comprises a junction box disposed at one end of the rail body, a base plate disposed on the junction box, two conductive terminals symmetrically disposed on the base plate, two conductive strips respectively disposed on the two conductive terminals, and a grounding terminal disposed on the base plate between the two conductive terminals. One end of the two conductive strips is respectively inserted into the two conductive terminals, and the other end of the two conductive strips has a socket portion that cooperates with the N-pole busbar and the L-pole busbar. One end of the N-pole busbar and the L-pole busbar is inserted into the socket portion, forming a snap-fit engagement between the N-pole busbar and the L-pole busbar and the two conductive strips.
[0005] The above structure has the following beneficial effects: a protective door is provided on the strip-shaped slot of the track body, which can cover the strip-shaped slot. The protective door is reset by a torsion spring, ensuring that the protective door can be securely covered on the strip-shaped slot, thereby improving protection performance. The terminal assembly adopts a modular structural design, and the N-pole busbar, L-pole busbar and the two conductive terminals of the terminal assembly are connected by plug-in connection, thereby facilitating modular assembly of the N-pole busbar, L-pole busbar and the terminal assembly, and ensuring a more compact connection between the N-pole busbar, L-pole busbar and the two conductive terminals. As a result, the power track has the advantages of simple structure, stable and reliable performance, high assembly efficiency, good protection performance, and high safety.
[0006] Specifically, one end of the grounding conductive sheet is riveted into the rail body, while the other end is inserted into the grounding terminal. This riveting of the grounding conductive sheet into the rail body facilitates assembly of the grounding conductive sheet and the rail body. When the rail socket is plugged into the power rail, the rail socket contacts the rail body, thereby achieving a grounding connection between the rail socket and the rail body.
[0007] Specifically, the protective door has a shielding portion on one side that fits within the strip-shaped slot, and two support arms on the other side. Each support arm is provided with two pivoting portions that mate with the support base. The support base is provided with two positioning slots that mate with the two pivoting portions. The two pivoting portions are inserted into the two positioning slots, respectively, to form a rotatable connection between the two pivoting portions and the support base. The protective door is rotatably mounted on the support base via the two pivoting portions, facilitating assembly of the protective door and the support base and ensuring that the protective door can reliably open or close, thereby improving the operational reliability of the power rail.
[0008] Specifically, the torsion spring is mounted on the rotating shaft. One end of the torsion spring has a U-shaped first torsion arm that engages with the shielding portion. The first torsion arm engages within a retaining groove in the shielding portion, while the second torsion arm at the other end of the torsion spring engages within a groove in the support seat. The torsion spring engages with the rotating shaft of the protective door, facilitating assembly of the torsion spring and the protective door, making assembly more convenient and ensuring that the protective door can be reliably opened or closed.
[0009] In particular, the support base is provided with a snap-fitting strip that mates with the track body, and the track body is provided with a snap-fitting groove that mates with the snap-fitting strip. The snap-fitting strip engages within the snap-fitting groove, thereby forming a snap-fitting connection between the snap-fitting strip and the track body. The snap-fitting assembly of the support base and the track body facilitates assembly of the support base and the track body, thereby increasing assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
