Abstract
Description
Technical Field
[0001] This utility model relates to the field of track socket technology, specifically to an ultra-thin track socket. Background Technology
[0002] Track sockets are a new type of socket product, mainly consisting of a power track and adapters. The power track, also known as a power rail, is typically installed on walls, tables, and baseboards. The adapters are installed on the power track, drawing power from it. Each adapter has a socket for plugging in electrical devices. Because the number of adapters installed on the power track can be increased or decreased as needed, and the positions of the adapters on the track can be adjusted freely, they are widely popular in the market.
[0003] The existing track socket structure has several shortcomings: The existing track socket has a conductive socket and a grounding busbar inside the power rail, and the adapter has a conductive prong and a copper rod. Power is drawn through the conductive prong of the adapter inserted into the conductive socket inside the power rail. The conductive socket inside the power rail of the existing track socket is long, resulting in high manufacturing costs. Furthermore, when multiple adapters are used on the power rail, the insertion port of the conductive socket is pushed open by the conductive prong of the previously inserted adapter, leading to unreliable connections for later-installed adapters, making the adapters prone to shaking and unstable contact. One end of the copper rod abuts against the grounding busbar, and the rigid contact structure between the copper rod and the grounding busbar results in a relatively thick overall structure. Moreover, the copper rod is prone to lateral displacement, leading to poor contact between the copper rod and the grounding busbar, causing grounding failure and posing a significant safety hazard. In addition, the adapters in the existing track sockets are fixed to the rail by internal locking keys, resulting in a complex structure and inconvenient use. Utility Model Content

The adapter 2 is provided with two conductive sockets, and an operating mechanism is provided inside the adapter 2 to control the conductive sockets to connect or disconnect from the metal conductive strips.
[0030] The adapter 2 is provided with a pin guard plate 21 below it. The pin guard plate 21 is provided with an elastic grounding component. The power rail 1 includes a rail housing 11. The rail housing 11 is provided with a rail grounding part. After the pin guard plate 21 of the adapter 2 is inserted into the power rail 1, it is connected to the rail grounding part through the elasticity of the elastic grounding component.
[0031] This embodiment employs an adapter 2 with a conductive socket combined with a flexible grounding component grounding electrode design. This simplifies the structure of the electric track, and the cost of the metal conductive strip used within the electric track is significantly lower than that of traditional metal conductive sockets used in tracks, thereby reducing track costs and ultimately lowering the overall cost and thickness. Furthermore, the flexible grounding component replaces the locking key function of the existing adapter, reducing the key structure while adding grounding functionality—a win-win situation!
[0032] To make the structural design of this utility model more reasonable, preferably, the track housing 11 in this embodiment is made of metal or plastic.

[0041] In practical applications, the adapter features a design combining a conductive socket with a flexible grounding component. The flexible structure of the grounding electrode and the use of a socket to clamp the conductive strip for the live and neutral wires simplify the structure of the power rail. The cost of the metal conductive strip used within the power rail is significantly lower than that of traditional metal conductive sockets used in rails, thus reducing the cost of the rail itself and consequently the overall cost and thickness. Furthermore, the flexible grounding component replaces the locking key function of existing adapters, reducing the key's structure while adding grounding functionality. This rational structural design makes it more convenient and practical to use.

When multiple adapters are used, each adapter connects or disconnects from the metal conductive strip via its own conductive sleeve, making the adapters secure and reliable and not easy to shake.
