Description

Technical Field

[0001] The utility model relates to a socket, in particular to a track socket. Background Art

[0002] With the widespread popularity of electronic and electrical products, the demand for electricity is increasing. Existing fixed sockets (wall sockets), mobile sockets (extension strips), etc., due to their fixed power supply positions, mismatched wire lengths, and complicated and intertwined power lines, often cannot meet the convenient power supply needs of electrical appliances. As a result, track sockets appeared on the market. "Track sockets" are also called "guide rail sockets", which are actually "track socket systems" consisting of two parts: power rails and track sockets, which are used in conjunction with each other. The power rail, also known as the power rail, power busbar, etc., has a straight busbar arranged inside, which is electrically connected to the fixed power supply wiring, and a long strip groove is opened on the outer surface, which can be installed openly or concealed on the surface of the wall, desk, furniture, etc. The track socket is also called an adapter, which is similar to a converter. It is a mobile electrical accessory composed of a contact part inserted into the track and one or more socket parts as an integral unit. The difference from the converter is that the converter draws power by inserting a plug into the socket, while the track socket draws power by inserting a matching power rail. For example, a Chinese patent with patent number CN202010778679.2 discloses an adapter and a track socket, in which a control component is used to control the expansion and storage of a movable conductive sheet relative to a guide body, thereby connecting and disconnecting the adapter from the track. The control component of the adapter adopts a double-spring control structure design, which has a relatively complex structural design, cumbersome assembly, and low reliability.

[0005] The beneficial effect of the above structure is that the operating mechanism uses the instantaneous structural design based on the instability principle of the compression spring and adopts a single spring structural design, which is simpler in structure, thereby ensuring that the electrical connection between the track socket and the power track can be switched open or closed instantly, which can effectively reduce arcing and help increase the electrical life of the track socket. During operation, the operating wheel is rotated, the operating wheel drives the operating rod to move, and the operating rod pushes the spring to twist, thereby realizing the connection or disconnection of the two electrical connectors and the power track.
