Abstract
Description
Technical Field
[0001] This application relates to the field of electrical component technology, specifically to a track socket. Background Technology
[0002] In the field of track socket technology, the combined application of power rails and adapters provides a flexible power supply method for electrical equipment. Among them, the adapter, as the core component for power supply, directly affects the stability and safety of power supply through its structural design. In the prior art, the adapter of a track socket typically includes a relatively rotatable housing, a base cover, and a base shell. The rotor of the base shell achieves contact or separation with the conductive conductors inside the power rail through rotation, thereby completing the power supply or power disconnection operation.
[0003] However, existing adapters have significant defects in their rotors during rotation: if the adapter is not fully inserted into the power rail and the rotor is accidentally rotated, it can easily misalign with the conductive conductor and the outer insulating support, or even become lodged in the gap between them. This not only results in poor power extraction but may also cause deformation of the conductive components, affecting the lifespan and safety of the power rail. Furthermore, some adapters have an unreasonable conductive structure layout, with insufficient contact stability between the neutral and live wire conductive components of the rotor and the socket inside the base shell. Frequent rotation can lead to poor contact, further reducing the reliability of the rail socket. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes: A track socket, comprising: The base shell has an insert sleeve inside; A movable ring is rotatably mounted on the base shell; A movable base plate is disposed inside the base shell and connected to the movable ring. A rotor is provided on the movable base plate and distributed coaxially therewith. The rotor extends out of the base shell. The conductive sheet includes a power-collecting arm and a contact arm connected to each other. The power-collecting arm is mounted on the rotor, and the contact arm extends into the base shell and contacts the socket. A locking mechanism is installed on the base shell and used to lock the movable base plate on the base shell. It is unlocked after the base shell is inserted into the power rail, so that the movable ring can drive the movable base plate and the rotor to rotate to the power-on position or the power-off position under the action of external force.
[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the locking mechanism includes a locking member, a movable rod and an elastic member.

[0012] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the base shell is provided with blocking members at both ends of the sliding track.
[0013] The beneficial effects of this utility model are as follows: After the track socket described in this application is inserted into the power rail and fully inserted, the locking mechanism unlocks the movable base plate, allowing the user to switch between power supply and power cutoff by rotating the movable ring.

[0019] Reference Figure 1-7 The present application proposes an embodiment of the track socket, which includes: The base shell 10 has an insert 30 inside; The movable ring 40 is rotatably mounted on the base shell 10; A movable base plate 50 is disposed inside the base shell 10 and connected to the movable ring 40. A rotor 51 is provided on the movable base plate 50 and is coaxially distributed therewith. The rotor 51 extends out of the base shell 10. The conductive sheet 70 includes a power-collecting arm 71 and a contact arm 72 connected to each other. The power-collecting arm 71 is mounted on the rotor 51, and the contact arm 72 extends into the base shell 10 and contacts the socket 30. The locking mechanism 80 is installed on the base shell 10 and is used to lock the movable base plate 50 on the base shell 10. It is unlocked after the base shell 10 is inserted into the power rail, so that the movable ring 40 can drive the movable base plate 50 and the rotor 51 to rotate to the power-on position or the power-off position under the action of external force.
[0020] The base shell 10 is provided with a receiving cavity 11, and a base plate 20 is provided in the receiving cavity 11. The insert 30 is installed on the base plate 20. The movable base plate 50 is located on the side of the base plate 20 away from the insert 30, and the rotor 50 is located on the side of the movable base plate 50 away from the base plate 20.
[0021] The locking mechanism 80 unlocks the movable base plate 50 only after the track socket is inserted into the power rail and fully inserted. Only then can the user rotate the movable ring 40 to make the power-taking arm 71 contact the conductive strip in the power rail to draw power, or to move the power-taking arm 71 away from the conductive strip to disconnect power. If the track socket is not inserted into the power rail or is not fully inserted, the locking mechanism 80 does not unlock. In this case, it is impossible to switch between power drawing and disconnection by rotating the movable base plate 50 with external force. This solves the problem of switching between power drawing and disconnection when the track socket is not fully inserted, ensuring service life and safety. The user only needs to rotate the movable ring 40 with external force to switch between power drawing and disconnection, making the operation simple and quick. In the overall structure, the movable ring 40, the movable base plate 50, and the base shell 10 have a compact fit, eliminating the need for complex transmission components. The contact arm 72 on the movable base plate 50 and the socket 30 on the base plate 20 always maintain contact, ensuring stable contact, stable and reliable power supply, avoiding poor contact between the conductive sheet 70 and the socket 30, and improving the reliability of the track socket.
[0022] In this embodiment, the locking mechanism 80 includes a locking member 81, a movable rod 82, and an elastic member 83. The movable base plate 50 is provided with a locking groove 52. The locking member 81 is disposed in the locking groove 52 and connected to one end of the movable rod 82. The other end of the movable rod 82 extends out of the base shell 10. The elastic member 83 is disposed in the base shell 10 and connected to the movable rod 82 and the base shell 10.
[0023] When the track socket is not fully inserted into the power rail, the movable rod 82 is not compressed by the power rail. Under the action of the elastic element 83, the locking element 81 will engage in the locking groove 52 of the movable base plate 50, restricting the rotation of the movable base plate 50 and thus preventing the neutral and live conductors of the rotor 51 from contacting the conductive strip in the power rail. Only when the track socket is fully inserted into the power rail, the power rail compresses the movable rod 82, causing the locking element 81 to disengage from the locking groove 52. Only then can the movable base plate 50 rotate to the power-taking position under the drive of the movable ring 40, preventing the rotor 51 from rotating accidentally when it is not aligned with the conductive strip, thus ensuring the safety of the track socket and the power-taking effect.
[0024] The elastic element 83 always applies force to the movable rod 82, making the locking element 81 and the locking groove 52 fit more tightly. In the non-powered state, the movable base plate 50 will not rotate due to external collisions or other unexpected situations, ensuring that the power-taking arm 71 is away from the conductive strip in the power rail and is in the power-off position.
[0025] Specifically, the conductive sheet 70 includes a live wire conductive sheet and a neutral wire conductive sheet, the socket 30 includes a live wire socket and a neutral wire socket, the contact arm 72 is mounted on the movable base plate 50, the contact arm 72 of the live wire conductive sheet contacts the live wire socket, and the contact arm 72 of the neutral wire conductive sheet contacts the neutral wire socket.
[0026] The contact arms 72 of the live wire conductive sheet and the neutral wire conductive sheet are directly mounted on the movable base plate 50 and designed in an arc shape to improve space utilization. During the rotation of the movable base plate 50, the live wire socket and the neutral wire socket always maintain contact with the live wire conductive sheet and the neutral wire conductive sheet, avoiding contact interruption or loosening caused by changes in the rotation angle, and avoiding poor contact due to deviation in rotation position.
[0027] This application also includes a grounding conductive sheet 90 and a conductive post 100. The socket 30 also includes a grounding socket. The grounding conductive sheet 90 is disposed inside the base shell 10 and contacts the grounding socket. One end of the conductive post 100 is connected to the grounding conductive sheet 90, and the other end extends out of the base shell 10.
[0028] The grounding conductive plate 90 maintains stable contact with the grounding socket. One end of the conductive post 100 is connected to the grounding conductive plate 90, and the other end extends out of the base shell 10. This allows the conductive post 100 to reliably connect to the grounding structure of the power rail when the rail socket is used with the power rail, meeting the requirements of electrical safety standards for grounding protection. Referring to the attached drawings, two conductive posts 100 are provided, each connected to both ends of the grounding conductive plate 90. One of the conductive posts 100 is integrated with the movable rod 82.
[0029] In this embodiment, the base shell 10 includes an outer shell and an insertion part for insertion into the power rail. The receiving cavity is disposed on the outer shell, and the conductive post 100 and the movable rod 82 both pass through the receiving cavity and out through the insertion part.
[0030] Furthermore, a fixing member 12 is provided in the receiving cavity 11, an extension 31 is provided on the insert 30, an elastic abutment member 32 is installed on the fixing member 12, and the elastic abutment member 32 abuts against the extension 31 and makes the extension 31 or the ground wire conductive sheet 90 contact.
[0031] The extension 31 is a copper sheet, which contacts the corresponding live wire conductive sheet, neutral wire conductive sheet or ground wire conductive sheet 90 under the action of the elastic abutment member 32, ensuring contact stability.
[0032] Preferably, a positioning element 110 is provided between the movable base plate 50 and the base shell 10, and the positioning element 110 is used to position the movable base plate 50 in the power-on position or the power-off position.
[0033] When the movable base plate 50 rotates to the power-on position under the drive of the movable ring 40, the positioning component 110 can fix it, ensuring stable contact between the conductor 60 of the rotor 51 and the conductive strip in the power rail. This prevents the movable base plate 50 from shifting due to accidental contact or vibration, thus preventing poor contact from affecting power supply. When the movable base plate 50 rotates to the power-off position, the positioning component 110 can also lock it, ensuring that the conductor 60 is completely separated from the conductive strip, eliminating the risk of accidental power-on.
[0034] Specifically, the positioning element 110 includes a spring plunger, the base shell 10 is provided with a sliding track 13, the two ends of the sliding track 13 are respectively provided with positioning holes 131, and the positioning element 110 is installed on the movable base plate 50 and extends into the sliding track 13.
[0035] When the spring plunger slides within the sliding rail 13, the resistance is smooth, and it produces a clear feedback when it engages or disengages from the positioning hole 131. Users can intuitively judge whether the movable base plate 50 has reached the target position by touch without additional observation, making the operation more convenient and efficient. The spring plunger has good elasticity and wear resistance, and its tight fit with the sliding rail 13 and positioning hole 131 results in minimal wear. It can maintain stable positioning performance during long-term and frequent rotation operations, reducing failures caused by the failure of the positioning component 110 and extending the service life of the rail socket.
[0036] Preferably, the base shell 10 is provided with blocking members 14 at both ends of the sliding track 13 to prevent the movable base plate 50 from moving out of the sliding track 13.
[0037] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
