Abstract
Description
Technical Field
[0001] The utility model relates to a power supply track, in particular to a waterproof ground 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 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, the L-pole busbar, and the ground busbar. Existing power tracks use two plastic strips as protective doors. These protective doors deform after a period of use and cannot be restored, resulting in a loss of protective performance and low safety. Furthermore, since the power track uses a plastic strip as a protective door, rainwater can enter the power track along the long slot, resulting in poor waterproof performance and a significant safety hazard. Summary of the Invention
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a waterproof ground power rail with simple structure, stable and reliable performance, high assembly efficiency, good protection performance and high safety.
[0004] To achieve the above-mentioned purpose, the utility model adopts a waterproof ground power rail including a base, a panel covering the base, an N-pole busbar arranged in the base, an L-pole busbar arranged in the base, a grounding conductive plate arranged in the panel, and a terminal assembly arranged in the base. The panel is respectively provided with a plurality of elongated jacks, and the panel is respectively provided with a waterproof protection door mechanism covering the plurality of elongated jacks. The waterproof protection door mechanism includes a support seat arranged in the panel, a protection door rotatably arranged on the support seat, and a torsion spring arranged between the support seat and the protection door. One end of the protection door has a shielding portion that cooperates with the elongated jack, and the shielding portion is provided with a waterproof rubber cap that seals with the elongated jack.
[0005] The above structure has the beneficial effect of providing a waterproof door mechanism on the panel, which provides waterproof and dustproof functions, preventing rainwater from entering the base through the long strip jack, thereby improving the waterproof performance of the ground power rail. As a result, the ground power rail has the advantages of simple structure, stable and reliable performance, high assembly efficiency, good protection performance, and high safety.
[0006] Specifically, insulating strips are provided on one side of the base corresponding to the plurality of elongated sockets. The N-pole busbar and L-pole busbar have N-pole and L-pole contact portions at their respective ends, which are inserted into two positioning slots in the insulating strip. The insulating strip is provided with insulating ridges separating the L-pole and N-pole contact portions. The integration of the N-pole and L-pole busbars on the insulating strips provides improved insulation performance and enables modular assembly of the N-pole and L-pole busbars with the base. The insulating ridges enhance the insulation between the N-pole and L-pole busbars, thereby improving the safety of the ground power rail.
[0007] Specifically, the terminal block assembly includes two conductive terminals and a grounding terminal disposed within the base. The N-pole busbar and L-pole busbar are provided with conductive plates inserted into the two conductive terminals. One end of the grounding conductive plate is inserted into the grounding terminal, and the other end of the grounding conductive plate is provided with a grounding screw connected to the panel. The N-pole busbar and L-pole busbar are connected to the conductive terminals using a plug-in connection, facilitating assembly of the N-pole busbar and L-pole busbar with the conductive terminals. The grounding conductive plate is connected to the panel via the grounding screws, and the track socket is pluggable with the power track. The track socket contacts the panel, achieving grounding of the ground power track, thereby ensuring more reliable grounding.
[0008] Specifically, the base is provided with a bottom cover that covers the terminal assembly. The bottom cover is provided with multiple clips, and the base is provided with slots that mate with the clips. The clips engage within the slots, forming a snap-fit connection between the bottom cover and the base. The bottom cover prevents exposure of the terminal assembly, thereby improving the reliability of the ground power rail. Furthermore, the bottom cover and base are assembled using a snap-fit connection, which enhances assembly efficiency.
[0009] In particular, the support base is symmetrically provided with two engaging posts, and the panel is provided with engaging grooves that cooperate with the two engaging posts. The engaging posts are inserted into the engaging grooves and constitute a snap-fitting connection between the support base and the panel. A fastener that connects to the panel is provided between the two corresponding engaging posts on the support base. The support base and the base are assembled using a snap-fitting method, thereby facilitating assembly of the support base and the base and improving assembly efficiency.
[0010] Specifically, the protective door has pivots at both ends, and the support base is provided with retaining grooves that mate with the pivots. The pivots are inserted into the retaining grooves, forming a rotational connection between the pivots and the support base. The protective door engages with the retaining grooves of the support base via the pivots, facilitating assembly of the protective door and the support base and ensuring reliable opening and closing of the protective door, thereby improving the operational reliability of the ground power rail.
[0011] In particular, the torsion spring is mounted on the rotating shaft, with one end of the torsion spring engaging with a groove in the shielding portion, and the other end engaging with a retaining groove in the support base. The torsion spring mounted on the rotating shaft facilitates assembly of the torsion spring and the protective door, making assembly more convenient. Furthermore, the torsion spring engages between the shielding portion and the support base, ensuring that the protective door can reliably open or close, thereby improving the operational reliability of the ground power rail.
