Description

Technical Field

[0001] This utility model relates to a socket, specifically a 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, application number CN202010778679.2 discloses an adapter and a track socket. The controller of the adapter adopts a dual-spring control structure design, which is relatively complex, cumbersome to assemble, has many parts, high cost, and 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 track socket that is simple in structure, stable and reliable in performance, easy to assemble, low in cost, long in service life and highly reliable.

[0004] To achieve the above objectives, this utility model employs a 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, two return springs disposed between the base and the two electrical connectors, 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 a lever rotatably mounted within the base and linked with the operating wheel. One end of the lever has two arc-shaped gear teeth that engage with the two electrical connectors. The two electrical connectors are respectively provided with gears that mesh with the two arc-shaped gear teeth, thus forming a linkage between the two electrical connectors and the lever.

[0005] The beneficial effects of the above structure are: the operating mechanism adopts a gear transmission design, which is simpler in structure, lower in cost, and provides smoother transmission. This ensures that the electrical connection between the track socket and the power rail can be switched on or off instantaneously, effectively reducing electric arcing and increasing the electrical life of the track socket. During operation, rotating the operating wheel causes the two electrical connectors to rotate via a lever, thereby connecting or disconnecting the two electrical connectors from the power rail. Therefore, this track socket has the advantages of simple structure, stable and reliable performance, convenient assembly, lower cost, and long service life.

[0006] Specifically, the other end of the lever has a deflector shaft that mates with the operating wheel. The operating wheel has a deflector hole that mates with the deflector shaft, and the deflector shaft passes through the deflector hole, forming a linkage between the deflector shaft and the operating wheel. The operating wheel drives the deflector shaft of the lever through the deflector hole, ensuring more reliable transmission between the operating wheel and the lever, and making the assembly of the lever and the operating wheel more convenient.

[0007] Specifically, a positioning boss is provided on one end of the lever corresponding to the two segments of the arc-shaped gear teeth, and a positioning hole is provided on the base to mate with the positioning boss. The positioning boss is rotatably disposed in the positioning hole, forming a rotatable connection between the positioning boss and the base. The lever is rotatably disposed in the positioning hole of the base through the positioning boss, thereby ensuring that the lever can reliably rotate within the base and facilitating the assembly of the lever and the base, making assembly more convenient.

[0008] Specifically, a grounding conductive rod is provided in the positioning hole of the base, and a through hole is provided on the positioning boss for the grounding conductive rod to pass through. One end of the grounding conductive rod passes through the through hole and is inserted into the insertion hole of the grounding socket. The other end of the grounding conductive rod has a grounding contact boss extending outside the base. The grounding conductive rod and the grounding socket are assembled by insertion, which facilitates the assembly of the grounding conductive rod and the grounding socket. Furthermore, the grounding conductive rod makes contact through the grounding contact boss, which ensures more reliable grounding.

[0009] Specifically, a positioning protrusion is provided at one end of the grounding conductive rod, and a compression spring is provided on the grounding conductive rod. One end of the compression spring abuts against the positioning protrusion, and the other end of the compression spring abuts against the grounding socket. The compression spring can increase the contact force of the grounding conductive rod, thereby improving the grounding reliability of the track socket.

[0010] Specifically, the two electrical connectors are provided with two limiting bosses that cooperate with the two return springs. One end of each return spring is engaged with one of the two limiting bosses, and the other end of each return spring is engaged with one of the two limiting grooves in the base. The return springs are engaged between the limiting bosses of the electrical connectors and the limiting grooves of the base, thereby facilitating the assembly of the return springs with the base and the electrical connectors, making assembly more convenient.

[0015] like Figures 1-4As shown, this utility model embodiment is a track socket, including a base 10, a cover 11 disposed on the base 10, two conductive sleeves 12 disposed inside the base 10, a grounding sleeve 13 disposed inside the base 10, two electrical connectors 14 rotatably disposed on the base 10 and electrically connected to the two conductive sleeves 12, two return springs 15 disposed between the base 10 and the two electrical connectors 14, and an operating mechanism 20 for controlling the connection and disconnection between the two electrical connectors 14 and the power track. The operating mechanism 20 includes an operating wheel 21 rotatably disposed on the base 10 and a lever 22 rotatably disposed inside the base 10 and linked with the operating wheel 21. One end of the lever 22 has two arc-shaped gear teeth 221 that cooperate with the two electrical connectors 14. The two electrical connectors 22 are respectively provided with gears 141 that mesh with the two arc-shaped gear teeth 221, thus forming a linkage between the two electrical connectors 14 and the lever 22. The other end of the lever 22 has a toggle shaft 222 that cooperates with the operating wheel 21. The operating wheel 21 is provided with a toggle hole 211 that cooperates with the toggle shaft 222. The toggle shaft 222 is inserted into the toggle hole 211, forming a linkage between the toggle shaft 222 and the operating wheel 21. The operating wheel drives the toggle shaft of the lever through the toggle hole, which ensures more reliable transmission between the operating wheel and the lever, and makes the assembly of the lever and the operating wheel more convenient. A positioning boss 223 is provided on one end of the lever 22 at the two segments of arc-shaped gear teeth 221. The base 10 is provided with a positioning hole 101 that cooperates with the positioning boss 223. The positioning boss 223 is rotatably disposed in the positioning hole 101, forming a rotatable connection between the positioning boss 223 and the base 10. The lever is rotatably mounted in the positioning hole of the base via a positioning boss, which ensures that the lever can rotate reliably in the base and facilitates the assembly of the lever and the base, making assembly more convenient.

[0016] like Figures 2-4As shown, a grounding conductive rod 16 is provided in the positioning hole 101 of the base 10. A through hole 224 is provided on the positioning boss 223 for the grounding conductive rod 16 to pass through. One end of the grounding conductive rod 16 passes through the through hole 224 and is inserted into the insertion hole 131 of the grounding socket 13. The other end of the grounding conductive rod 16 has a grounding contact boss 161 extending outside the base 10. The grounding conductive rod and the grounding socket are assembled by insertion, which facilitates the assembly of the grounding conductive rod and the grounding socket. Furthermore, the grounding conductive rod contacts the grounding contact boss, ensuring more reliable grounding. A positioning protrusion ring 162 is provided on one end of the grounding conductive rod 16, and a compression spring 17 is provided on the grounding conductive rod 16. One end of the compression spring 17 abuts against the positioning protrusion ring 162, and the other end of the compression spring abuts against the grounding socket 13. The compression spring increases the contact force of the grounding conductive rod, thereby improving the grounding reliability of the track socket. The two electrical connectors 14 are provided with two limiting bosses 142 that cooperate with the two return springs 15. One end of each return spring 15 is engaged with the two limiting bosses 142, and the other end of each return spring 15 is engaged with the two limiting grooves 102 of the base 10. The return springs are engaged between the limiting bosses of the electrical connectors and the limiting grooves of the base, which facilitates the assembly of the return springs with the base and the electrical connectors, making assembly more convenient.

[0017] The operating mechanism employs a gear transmission design, which is simpler, lower in cost, and provides smoother transmission. This ensures that the electrical connection between the track socket and the power rail can be instantly switched on or off, effectively reducing electric arcing and extending the electrical life of the track socket. During operation, rotating the operating wheel, which in turn moves the two electrical connectors via a lever, connects or disconnects them from the power rail. Therefore, this track socket offers advantages such as simple structure, stable and reliable performance, convenient assembly, lower cost, and long service life.
