Description

Technical Field

[0001] This utility model relates to a socket, specifically a highly reliable track socket. Background Technology

[0002] With the widespread use of electronic and electrical products, the demand for power is constantly increasing. Existing fixed sockets (wall sockets) and mobile sockets (power strips) often fail to meet the convenient power needs of appliances due to limitations such as fixed power supply locations, mismatched cord lengths, and tangled power cords. Therefore, track sockets have emerged on the market. Also known as "rail sockets," track sockets are actually "track socket systems," consisting of a power rail and track sockets used together. The power rail, also called an electrical rail or power busbar, has straight busbars inside, electrically connecting to the fixed power supply wiring. Its external surface has elongated grooves, allowing for surface or recessed mounting on walls, desks, furniture, etc. Track sockets, also called adapters, are similar to converters. They are portable electrical accessories consisting of a contact part that inserts into the rail and one or more socket parts as a single unit. The difference between a converter and a track socket is that a converter draws power by inserting a plug into a socket, while a track socket draws power by inserting into a matching power rail. For example, Chinese patent CN202010778679.2 discloses an adapter and a track socket. The adapter's control components adopt a dual-spring control structure design, which is relatively complex, has many parts, is cumbersome to assemble, and has low reliability. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a highly reliable track socket that is simple in structure, stable and reliable in performance, convenient in assembly, and has a long service life.

[0004] To achieve the above objectives, this utility model employs a highly reliable track socket, comprising a base, a cover mounted on the base, two conductive sleeves disposed within the base, a grounding sleeve disposed within the base, two electrical connectors rotatably mounted on the base and electrically connected to the two conductive sleeves, and an operating mechanism for controlling the connection and disconnection between the two electrical connectors and the power track. The operating mechanism includes an operating wheel rotatably mounted on the base and two return springs disposed between the two electrical connectors and the base. One end of each electrical connector has a sector gear, and the operating wheel contains arc-shaped teeth that mesh with the sector gear. The arc-shaped teeth mesh with the sector gear, forming a linkage between the electrical connector and the operating wheel.

[0005] The beneficial effects of the above structure are as follows: The operating mechanism adopts a single-spring structure design, which is simpler and ensures that the electrical connection between the track socket and the power rail can be switched instantaneously, effectively reducing electric arcing and increasing the electrical life of the track socket. During operation, rotating the operating wheel causes its arc-shaped teeth to drive the sector gears of the two electrical connectors. These sector gears then drive the two electrical connectors to move, thus connecting or disconnecting them from the power rail. Therefore, this track socket has the advantages of simple structure, stable and reliable performance, convenient assembly, and long service life.

[0006] Specifically, the base is provided with an arc-shaped guide plate, and the operating wheel is provided with a guide hole that mates with the arc-shaped guide plate. The arc-shaped guide plate is inserted into the guide hole, forming a sliding connection between the operating wheel and the arc-shaped guide plate. The arc-shaped guide plate of the base is inserted into the guide hole of the operating wheel, which facilitates the assembly of the operating wheel and the base and ensures that the operating wheel can reliably move on the base, thereby improving the working reliability of the track socket.

[0007] Specifically, the electrical connector is provided with a positioning post that cooperates with the return spring. One end of the return spring is engaged with the positioning post, and the base is provided with a positioning groove that cooperates with the return spring. The other end of the return spring is engaged in the positioning groove. The return spring is engaged in the positioning post of the electrical connector and the positioning groove of the base, which facilitates the assembly of the return spring with the electrical connector and the base, making assembly more convenient and ensuring reliable operation of the electrical connector.

[0008] Specifically, one end of the conductive sleeve has two symmetrically distributed clamping plates, with a clamping cavity formed between the two clamping plates. The electrical connector has a conductive post that passes through the clamping cavity, forming a rotatable connection between the conductive post and the two clamping plates. The electrical connector's insertion into the clamping cavity of the conductive sleeve facilitates assembly between the electrical connector and the conductive sleeve, making assembly more convenient and ensuring a more reliable connection between the electrical connector and the conductive sleeve.

[0009] Specifically, the base is equipped with a grounding conductive rod that mates with a grounding socket. A compression spring is provided between the grounding conductive rod and the grounding socket. One end of the grounding conductive rod is rotatably disposed within the insertion cavity of the grounding socket. The grounding conductive rod has a grounding contact portion extending outside the base. The grounding socket achieves grounding through the grounding conductive rod, and the compression spring increases the contact pressure of the grounding conductive rod, making the grounding more reliable.

[0010] Specifically, the compression spring is fitted onto the grounding conductive rod, which has a positioning protrusion that cooperates with the compression spring. One end of the compression spring abuts against the positioning protrusion, and the other end abuts against the grounding sleeve. Fitting the compression spring onto the grounding conductive rod facilitates the assembly of the grounding conductive rod and the compression spring, and the compression spring increases the contact pressure of the grounding conductive rod, resulting in more reliable grounding.

The operating mechanism 20 includes an operating wheel 21 rotatably disposed on the base 10 and two return springs 22 disposed between the two electrical connectors 14 and the base 10. One end of the electrical connector 14 has a sector gear 141, and the operating wheel 21 is provided with an arc-shaped tooth 211 that meshes with the sector gear 141. The arc-shaped tooth 211 meshes with the sector gear 141 and constitutes a linkage between the electrical connector 14 and the operating wheel 21. The base 10 is provided with an arc-shaped guide plate 101, and the operating wheel 21 is provided with a guide hole 212 that cooperates with the arc-shaped guide plate 101. The arc-shaped guide plate 101 is inserted into the guide hole 212, forming a sliding connection between the operating wheel 21 and the arc-shaped guide plate 101. The arc-shaped guide plate of the base is inserted into the guide hole of the operating wheel, which facilitates the assembly of the operating wheel and the base and ensures that the operating wheel can reliably move on the base, thereby improving the working reliability of the track socket. The electrical connector 14 is provided with a positioning post 142 that cooperates with the return spring 22. One end of the return spring 22 is engaged with the positioning post 142, and the base 10 is provided with a positioning groove 102 that cooperates with the return spring 22. The other end of the return spring 22 is engaged with the positioning groove 102.

The conductive sleeve 12 has two symmetrically distributed clamping pieces 121 at one end, forming a clamping cavity 120 between the two clamping pieces 121. The electrical connector 14 has a conductive post 143 that passes through the clamping cavity 120, forming a rotatable connection between the conductive post 143 and the two clamping pieces 121. One end of the electrical connector is inserted into the clamping cavity of the conductive sleeve, facilitating assembly of the electrical connector and the conductive sleeve, making assembly more convenient, and ensuring a more reliable connection between the electrical connector and the conductive sleeve.

[0015] like Figure 2 and 3As shown, a grounding conductive rod 15 is provided inside the base 10 to cooperate with the grounding socket 13. A compression spring 16 is provided between the grounding conductive rod 15 and the grounding socket 13. One end of the grounding conductive rod 15 is rotatably disposed in the insertion cavity 131 of the grounding socket 13. The grounding conductive rod 15 has a grounding contact portion 151 extending outside the base 10. The grounding socket achieves grounding through the grounding conductive rod, and the compression spring can increase the contact pressure of the grounding conductive rod, making the grounding more reliable. The compression spring 16 is fitted onto the grounding conductive rod 15. The grounding conductive rod 15 has a positioning protrusion 152 that cooperates with the compression spring 16. One end of the compression spring 16 abuts against the positioning protrusion 152, and the other end of the compression spring abuts against the grounding socket 13. The compression spring is fitted onto the grounding conductive rod, which facilitates the assembly of the grounding conductive rod and the compression spring, and the compression spring can increase the contact pressure of the grounding conductive rod, making the grounding more reliable.

[0016] The operating mechanism employs a single-spring structure, resulting in a simpler design that allows for instantaneous switching of the electrical connection between the rail socket and the power rail. This effectively reduces electric arcing and extends the electrical life of the rail socket. During operation, rotating the operating wheel causes its arc-shaped teeth to drive the sector gears of the two electrical connectors. These sector gears then actuate the two electrical connectors, thus connecting or disconnecting them from the power rail. Therefore, this rail socket offers advantages such as simple structure, stable and reliable performance, convenient assembly, and long service life.
