Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an adapter of a track socket and an assembly structure of the adapter and the track socket. Background Art

[0002] Track socket is a socket that can be added, reduced, moved and changed in position at any time within the track range. It can solve the disadvantage of traditional power sockets that cannot be moved in the installation position.

[0003] Existing track sockets typically consist of an adapter and a bar-shaped track. The track is mounted on the wall, and the adapter plugs into the track's slot to connect to the track's conductive strip. Electrical appliances plug into the adapter's jack to connect and draw power. However, existing adapters are often complex, with numerous moving parts. Connecting and disconnecting the electrical connection between the adapter and the track requires complex movement, taking up considerable space. Furthermore, existing adapters typically do not restrict the direction of connection between the adapter and the track. This can make it difficult for users to detect when the track is reversed or the adapter is inserted backward, posing a safety hazard. Furthermore, existing adapters often employ fixed protrusions on the housing surface to prevent misalignment, making the product less aesthetically pleasing. Summary of the Invention

[0004] The purpose of the present invention is to overcome at least one of the drawbacks of the prior art and provide an adapter for a track socket. To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Furthermore, the anti-idiot mechanism includes a raised anti-idiot block for cooperating with a slide groove on one side of the track. When the adapter is connected to the track in the forward direction, the anti-idiot block rotates with the rotating contact piece into the slide groove. When the adapter is connected to the track in the reverse direction, the anti-idiot block is limited so that the rotating contact piece cannot drive the conductive pin to rotate to a position connected to the conductive sheet on the track.

[0007] Furthermore, the rotating contact piece rotates between a first position and a second position, and the connecting portion is provided with a receiving groove. When the rotating contact piece rotates to the first position, the conductive pin is received in the receiving groove and separated from the conductive sheet. When the rotating contact piece rotates to the second position, the conductive pin extends from the receiving groove and is connected to the conductive sheet.

[0008] Furthermore, the rotating contact piece includes two connectors, which are rotationally symmetrical about the central axis of the socket body. Each connector includes a conductive pin and a conductive shaft arranged perpendicular to the conductive pin. One end of the conductive shaft is connected to the conductive pin, and the other end is in direct contact with the fixed socket to achieve electrical connection. Its axis is parallel to the central axis of the socket body. When the control piece rotates around the central axis, the rotating contact piece is driven to rotate around the axis of the connector.

[0009] Furthermore, the connector also includes a driving member sleeved on the conductive shaft for driving the connector to perform circular motion around the conductive shaft.

[0012] Furthermore, the conductive component also includes a fixed disk, which is arranged between the fixed sleeve and the rotating contact member. The fixed disk is provided with a sleeve groove and a track groove. The fixed sleeve is installed in the sleeve groove. The drive shaft on the rotating contact member passes through the track groove and is connected to the operating member and moves in the track groove.

[0013] Furthermore, the fixed disk and the operating member are respectively provided with positioning components that cooperate with each other, and when the operating member drives the rotating contact member to rotate to the first position or the second position, the positioning component fixes the operating member.

[0014] Furthermore, the positioning assembly includes a convex rib and a baffle, the convex rib is provided on a side of the fixed plate facing the operating member, and the operating member is provided with at least one set of baffles, and the baffles are fixed to the convex rib by friction.

[0015] Furthermore, a first threading hole is provided at the center of the fixed disk, and second threading holes are symmetrically provided on both sides of the first threading hole. The rotating contact part passes through the second threading holes and is electrically connected to the fixed socket.

[0016] Furthermore, the conductive component further includes a grounding shaft, one end of which is connected to the fixed socket, and the other end of which extends out of the socket body through a through hole provided on the connecting portion.

[0017] Furthermore, it also includes a locking mechanism, which is arranged in the socket body and partially extends out of the socket body, and is used to lock the socket body on the track. The locking mechanism includes a locking piece, a return spring, and an operating mechanism. A limiting structure is provided in the socket body, and the locking piece and the return spring are slidably arranged in the limiting structure. One end of the operating mechanism extends out of the socket body, and the other end is connected to the locking piece. The locking piece includes a hook extending from the connecting portion along the receiving groove. Pressing the operating mechanism drives the locking piece to slide radially along the socket body in the limiting structure and compress the return spring, so that the hook is received in the receiving groove.

[0018] Furthermore, the locking member also includes a connecting plate, which is slidably arranged in the limiting structure, and a avoidance hole is provided in the middle thereof, on which a hook and an integrally formed contact portion are provided, and the contact portion and the operating mechanism abut against each other, and the reset spring is arranged in the avoidance hole along the movement direction of the locking member, and the two ends are respectively connected to the connecting plate and the socket body.

[0019] Furthermore, the conductive assembly further includes a placeholder, which is assembled into the receiving slot together with the rotating contact piece, and the placeholder fills the gap between the rotating contact piece and the receiving slot.

[0020] Furthermore, the socket body also includes a panel and a base that are spaced apart and interconnected. A socket is provided on the panel, and a connecting portion is formed on the side of the middle of the base facing away from the panel.

[0023] The utility model also provides an adapter and track socket assembly structure, comprising an adapter and a track, wherein one side of the track is provided with a track fool-proof mechanism that cooperates with the fool-proof mechanism of the adapter.

[0024] The adapter of the track socket of the present invention arranges the anti-mock mechanism at the position corresponding to the rotating contact and the connecting part, and cooperates with the track anti-mock mechanism on one side of the track to prevent the reverse connection of the neutral and live wires, thereby ensuring the safety of electricity use. Moreover, the anti-mock mechanism rotates into the connecting part with the rotating contact, and rotates out to the connecting part with the rotating contact after being inserted into the track. The overall appearance is beautiful and does not affect the external structure of the adapter and the track.

[0025] In addition, the rotating contact piece for electrically connecting to the track is directly driven by the operating piece, and there is no need to set up additional components to indirectly drive the rotation. At the same time, the rotating axes of the connector on the operating piece and the rotating contact piece are parallel to each other, and only rotate on the same horizontal plane during the rotation process, without generating axial displacement, effectively saving internal space, and having the characteristics of simple structure, low cost, and smooth and controllable rotation.

[0026] In addition, a positioning component is set on the control piece and the fixed plate. When the control piece is rotated into position, the user is prompted and the position is fixed, avoiding poor contact due to improper rotation or accidental touch, thereby ensuring the safety of the adapter during use.

[0027] In addition, the expansion and contraction of the rotary contact piece is achieved only by the structures on the operating piece and the fixing piece, which reduces the number of parts and saves internal space.

[0028] In addition, a locking component is provided on the adapter to make the connection between the adapter and the track more secure, ensuring safe use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the track socket adapter of the present invention. The track socket adapter of the present invention is not limited to the description of the following embodiments.

[0045] like Figure 1-4As shown, the track socket of this embodiment includes a track 7 and at least one adapter, each adapter including a socket body of approximately cylindrical shape, one end of the socket body being provided with a socket 111, and the other end being provided with a connecting portion 130 for connecting to the track 7, the connecting portion 130 being inserted into the track 7, and an operating member 12 and a conductive component 3 being provided between the socket 111 and the connecting portion 130; the conductive component 3 including a fixed socket 31 and a rotating contact member 32 being electrically connected to each other, one end of the rotating contact member 32 being provided with a conductive pin 3211 being installed in the connecting portion 130, and the other end being connected to the operating member 12, when the operating member 12 rotates, the rotating contact member 32 is driven to rotate, so that the conductive pin 3211 of the rotating contact member 32 extends from the connecting portion 130 and connects to the conductive sheet 71 on the track 7.

[0046] like Figure 2-3 As shown, panels 11 and bases 13 connected to each other are spaced apart at both ends of the socket body, which are used to connect to external electrical appliances and the track 7 respectively. The panel 11 and the base 13 are provided with connecting columns facing each other and fixed to each other by screws 8. The centers of both are located on the central axis a of the socket body. A socket 111 is provided in the center of the panel 11. The socket 111 is a two-phase and / or three-phase socket. A connecting portion 130 is formed in the center of the base 13 in the direction away from the panel 11. The connecting portion 130 is an axially extending flat protrusion for connecting the adapter to the track 7. A receiving groove 131 is provided on the connecting portion 130. The opening direction of the receiving groove 131 is opposite to the conductive sheet 71 on the track 7.

[0047] Since the adapter does not distinguish between directions when connected to the track 7, it is only necessary to connect the connecting portion 130 to the track 7 and then rotate the operating member 12 to obtain power. There is a risk of reverse connection of the neutral and live wires. Therefore, this embodiment provides an anti-fool mechanism 5 for preventing reverse connection, such as Figure 1 、 3 As shown, the anti-fool mechanism 5 is arranged on the rotating contact member 32, and is located at a position corresponding to the rotating contact member 32 and the connecting portion 130, and is used to cooperate with the track anti-fool mechanism on one side of the track 7. The anti-fool mechanism 5 and the conductive pin 3211 can be rotated out of or into the connecting portion 130 along with the rotating contact member 32, so that only when the adapter is connected to the track 7 from the correct direction, the rotating operating member 12 can drive the conductive pin 3211 of the rotating contact member 32 to rotate out of the connecting portion 130 and connect with the conductive sheet 71 on the track 7.

[0048] Specifically, the anti-idiot mechanism 5 includes a raised anti-idiot block 51, and the corresponding track anti-idiot mechanism is a slide groove 52 opened on one side of the track 7. No slide groove 52 is set on the other side of the track 7. When the adapter is inserted into the track 7 in the correct direction, the operating member 12 is rotated in one direction (such as clockwise). The operating member 12 drives the conductive pin 3211 of the rotating contact member 32 to rotate out of the connecting part 130. At the same time, the anti-idiot block 51 is rotated into the slide groove 52, and the conductive pin 3211 rotates to connect with the conductive sheet 71 on the track 7. If the adapter is inserted into the track 7 in the wrong direction, and the operating member 12 is rotated in one direction (e.g., clockwise), the operating member 12 drives the conductive pin 3211 of the rotating contact member 32 out of the connecting portion 130. Since there is no slot 52 on the other side of the track 7, the anti-crash block 51 on the rotating contact member 32 is limited, preventing the rotating contact member 32 from driving the conductive pin 3211 to a position where it connects with the conductive piece 71 on the track 7. In other words, the adapter can be connected in a single direction, preventing the neutral and live wires from being reversed (preventing the adapter's neutral wire from connecting to the live wire of the track 7), thus ensuring electrical safety. Obviously, in other embodiments, the anti-crash mechanism 5 can also be a groove provided on the rotating contact member 32, with the corresponding track anti-crash mechanism on one side of the track 7 being an anti-crash block.

[0049] The adapter of the track socket of this embodiment sets the anti-mock mechanism 5 at the position corresponding to the rotating contact 32 and the connecting part 130. Cooperating with the track anti-mock mechanism on one side of the track, it can prevent the reverse connection of the neutral and live wires, ensuring electrical safety. Moreover, the anti-mock mechanism 5 rotates into the connecting part 130 with the rotating contact 32, and rotates out to the connecting part 130 with the rotating contact 32 after being inserted into the track 7. The overall appearance is beautiful and does not affect the external structure of the adapter and the track 7.

[0050] like Figure 4 As shown, the operating member 12 is located between the panel 11 and the base 13, and is surrounded by the panel 11 and the base 13 to form a hollow shell 1, and can rotate relative to the panel 11 and the base 13. The operating member 12 is preferably a ring-shaped structure, and its two end edges are respectively slidably matched with the panel 11 and the base 13. In this embodiment, the operating member 12 is divided into an integrally formed outer ring and an inner ring. One end of the inner ring extends toward the base 13 and slidably matches with the inner side wall of the base 13, and the other end forms an inward stepped structure with the inner side wall of the outer ring for sliding with the panel 11. Preferably, the operating member 12 rotates around its axis, and the axis of the operating member 12 is located on the central axis a of the socket body. In this way, except for the rotation, the relative position of the operating member 12 does not change, so that the rotation is more stable and controllable.

[0051] like Figure 4 、 11As shown, one end of the conductive component 3 corresponds to the socket 111 and is used to connect to an external electrical appliance, and the other end extends into the connecting portion 130 and extends out of the connecting portion 130 as the operating member 12 rotates, and is used to connect to the track 7; the conductive component 3 includes a fixed socket 31 and a rotating contact member 32 that are electrically connected to each other. The fixed socket 31 can adopt the existing technology. In this embodiment, the fixed socket 31 is divided into a first socket and a pair of second sockets symmetrically arranged with each other, and its position corresponds to the socket 111, and is used to connect with the electrical appliance when the electrical appliance is inserted into the adapter through the socket 111. Plug connection, each second socket includes two jacks, and a first socket is provided between the two second sockets, and the first socket is used for grounding; one end of the rotating contact member 32 is installed in the connecting part 130, and the other end is connected to the operating member 12. The end of the rotating contact member 32 extending into the connecting part 130 is provided with a conductive pin 3211. When the operating member 12 rotates around the central axis a, the rotating contact member 32 is driven to rotate around its own axis, so that the conductive pin 3211 of the rotating contact member 32 extends from the connecting part 130 and connects to the conductive sheet 71 on the track 7 to complete power collection.

[0052] Specifically, the rotating contact member 32 rotates between the first position and the second position. Figure 2-4 As shown, the disc groove of the base 13 is connected to the connecting part 130 through the receiving groove 131, and the rotating contact member 32 extends into the receiving groove 131 through the part that is connected to the connecting part 130 through the base 13, so that the conductive pin 3211 at one end thereof can extend from the connecting part. When the rotating contact member 32 rotates to the first position, the conductive pin 3211 is received in the receiving groove 131 and separated from the conductive sheet 71. At this time, the adapter can be inserted into or removed from the track 7; when the rotating contact member rotates to the second position, the conductive pin 3211 extends from the receiving groove 131 and is connected to the conductive sheet 71.

[0053] like Figure 4 , and 9-11, as an embodiment of the rotating contact member 32, it includes two connectors 321, each connector 321 includes a conductive pin 3211 and a conductive shaft 3212 arranged perpendicular to the conductive pin 3211, one end of the conductive shaft 3212 is connected to the conductive pin 3211, and the other end extends into the base 13 and directly contacts the fixed socket 31 to achieve electrical connection, the conductive shaft 3212 is preferably cylindrical, and its axis is parallel to the central axis a of the socket body. When the operating member 12 rotates around the central axis a, the rotating contact member 32 is driven to rotate around the axis of the connector 321, and the two connectors 321 are rotationally symmetrical about the central axis a of the socket body, that is, when the rotating contact member 32 rotates, the two conductive pins 3211 extend from opposite directions and are respectively connected to the conductive sheets 71 on both sides of the track 7.

[0054] The connecting body 321 also includes a driving member 3210, through which the operating member 12 is connected to the connecting body 321 and drives it to rotate. The driving member 3210 is sleeved on the conductive shaft 3212 and extends axially toward both ends of the conductive shaft 3212. One end extends into the base 13 and forms a plate-like structure with a certain thickness along the radial direction of the bottom surface of the base 13. The end of the other end forms a protrusion that engages with the connecting portion 130 and partially wraps the conductive pin 3211. Figure 6 、 10 As shown, a group of drive grooves 121 are provided on the inner ring of the operating member 12, and their positions correspond to the rotating contact members 32. The plate-like structure extends to the bottom of the drive grooves 121, and a drive shaft 3213 is provided upward. The drive grooves 121 and the drive shaft 3213 are plugged into and matched to form a drive structure. When the operating member 12 rotates, the drive structure drives the drive member 3210 to rotate, and then drives the conductive pin 3211 to rotate with the conductive shaft 3212 as the axis. It can also be understood that the function of the drive member 3210 is to make the connecting body 321 perform circular motion with the operating member 12 with the conductive shaft 3212 as the axis; of course, the drive member 3210 is not limited to the shape and structure described in this embodiment, and it may not wrap the conductive pin or have a protrusion. It only needs to be able to fix the position of the rotating shaft and drive the conductive pin 3211 to rotate. In addition, the specific shape of the plate-like structure is not limited, and is preferably V-shaped.

[0055] Preferably, a directional baffle is provided on the base 13, such as Figure 9 As shown, when the rotary contact member 32 is in the first position, the baffle abuts against the plate structure in the opposite direction of its movement toward the second position, thereby preventing the rotary contact member 32 from rotating in the opposite direction.

[0056] The adapter of the track socket of this embodiment is directly driven by the operating member 12 to rotate the rotating contact member 32 for electrically connecting to the track, without the need for additional components to indirectly drive the rotation. At the same time, the operating member 12 and the rotating shaft of the connector 321 on the rotating contact member 32 are parallel to each other. During the rotation process, they only rotate on the same horizontal plane and will not produce axial displacement, effectively saving internal space. It has the characteristics of simple structure, low cost, and smooth and controllable rotation.

[0057] As a preferred embodiment of the foolproof mechanism 5, Figure 1-3As shown in FIG12, the connector 321 is provided with the anti-idiot block 51 in the same direction as the conductive pin, and the anti-idiot block 51 rotates coaxially with the conductive pin. Preferably, the anti-idiot block 51 is a protrusion of the driving member 3210 located on the exposed portion inside and outside the receiving groove 131, and its width is substantially the same as that of the conductive pin 3211. The slide 52 is provided on the side wall where the track 7 contacts the connecting portion 130. When the adapter is positively connected to the track 7, the positions of the anti-idiot block 51 and the slide 52 correspond exactly. When the rotating contact member 32 is in the first position and the second position When the adapter is rotated, the anti-idiot block 51 slides in and out of the slide groove 52. Specifically, when the connector 321 is rotated to the second position, the anti-idiot block 51 extends out together with the conductive pin 3211 and enters the slide groove 52. When the connector 321 is rotated to the first position, the anti-idiot block 51 is received into the receiving groove 131 together with the conductive pin 3211. At this time, the anti-idiot block 51 does not affect the insertion and removal of the adapter. Only when the adapter is inserted in the reverse direction will the anti-idiot block 51 abut against the inner side wall of the track 7, causing the rotating contact member 32 to be unable to rotate.

[0058] Of course, the anti-mute block 51 can also be set on the connecting part 130 in a fixed manner. It is only necessary to make corresponding changes to the shape and setting position of the corresponding slide groove 52 as in the prior art, or change the access method of the adapter to access from a specific position of the track 7 to achieve the purpose of directional access. Only the preferred solution is given here.

[0059] like Figure 7-10 As shown, the conductive component 3 also includes a fixed disk 33, which is arranged between the fixed sleeve 31 and the rotating contact member 32. The rotating contact member 32 passes through the fixed disk 33 and is connected to the fixed sleeve 31. The fixed disk 33 separates the fixed sleeve 31 and the rotating contact member 32 to avoid mutual interference during rotation. The fixed disk 33 is circular as a whole, with a diameter less than or equal to the inner diameter of the disc groove of the base 13. The fixed disk 33 is limitedly installed in the base 13 and the distance between it and the bottom surface of the base 13 is greater than the thickness of the plate-like structure on the driving member 3210. It is provided with a socket groove 330 and a track groove 331. The socket groove 330 is arranged in the direction toward the panel 11 and its position corresponds to the socket 111. The fixed socket 31 is limitedly set on the socket groove 330; the track groove 331 is opened on both sides of the fixed disk 33, and its shape is the same as the movement trajectory of the driving shaft 3213, and the two track grooves 331 are rotationally symmetrical about the center of the fixed disk 33. The driving shaft 3213 passes through the track groove 331 and is plugged into the driving groove 121. When the operating member 12 rotates, the driving shaft 3213 slides along the track groove 331. The two ends of the track groove 331 correspond to the extreme positions of the conductive pin 3211 when it is retracted and extended, namely the first position and the second position.

[0060] A first threading hole 332 is provided at the center of the fixed disk 33, and symmetrical second threading holes 333 are provided on both sides. The position of the first threading hole 332 corresponds to the first socket, and the rotating contact member 32 partially passes through the second threading hole 333 to be electrically connected to the fixed socket 31. In this embodiment, the conductive shaft 3212 on each connector 321 passes through the second threading hole 333 and is rotatably connected to the second socket. The center line of the track groove 331, the first threading hole 332 and the second threading hole 333 is on a diameter of the fixed disk 33.

[0061] Specifically, the shape of the socket slot 330 is adapted to the two-phase and / or three-phase socket 111. In this embodiment, the socket 111 is distributed as in the prior art, with five pins corresponding to the two-phase and three-phase pins, respectively. Accordingly, the socket slot 330 includes five limit slots corresponding to the socket 111, and its shape is bilaterally symmetrical, and the axis of symmetry is perpendicular to the center line connecting the track slot 331, the first threading hole 332 and the second threading hole 333. The second sockets are arranged in pairs in the limit slots on the left and right sides, with the first socket arranged in the middle. The first socket is located above the first threading hole 332, and the middle of each second socket extends to above the second threading hole 333; when the appropriate When the adapter is assembled, the conductive shaft 3212 extends from the second threading hole 333 to be rotationally connected to the second socket and electrically connected. The drive shaft 3213 extends from the first position of the track groove 331 to be plugged into the drive groove 121. The operating member 12 is rotated, and the drive shaft 3213 moves from the first position to the second position along the track groove 331. The rotating contact member 32 located below the fixed disk 33 rotates accordingly. The conductive shaft 3212 rotates in the second threading hole 333 while maintaining its relative position. During the rotation process, the fixed socket 31, the rotating contact member 32 and the fixed disk 33 are interconnected but do not interfere with each other. The track groove 331 also serves to limit their movement trajectory.

[0062] Preferably, the fixed disk 33 and the operating member 12 are respectively provided with a positioning assembly 6 that cooperates with each other. When the operating member 12 is rotated into place, it is fixed, that is, when the operating member 12 drives the rotating contact member 32 to rotate to the first position or the second position, the positioning assembly 6 fixes the operating member 12. The positioning assembly 6 includes a rib 62 and a baffle 61 provided on the operating member 12 and the fixed disk 33. The rib 62 has a protrusion formed in the direction of the baffle 61, and the baffle 61 is provided with a recess that matches the protrusion. The two are fixed by friction. When the rib 62 and the baffle 61 are engaged, the operating member 12 is fixed in this position. It is necessary to apply a certain force to the operating member 12 in the rotation direction to make the two out of the fixed state before they can continue to rotate. It can be understood that when the rib 62 and the baffle 61 are set at different positions, the fixed position of the operating member 12 on the rotation path will also change accordingly.

[0063] like Figure 6 、 9As shown in Figure 10, the positioning assembly 6 of this embodiment includes a group of ribs 62 provided on the fixed plate 33 and two groups of baffles 61 provided on the operating member 12. The ribs 62 are provided on the side of the fixed plate 33 facing the operating member 12, and the side facing the operating member 12 is a contact surface, and the center of the contact surface forms an arc-shaped protrusion outward. The side of the baffle 61 facing the ribs 62 is a corrugated type with a central depression. When the two are in a fixed state, the protrusion on the ribs 62 is just embedded in the depression in the center of the baffle 61; specifically, when the operating member 12 is in the first position, the ribs 62 are embedded in the baffle 61. At this time, the operating member 12 is rotated and a certain force is applied to it, so that the ribs 62 and the first group of baffles are engaged. 61 separates and continues to rotate toward the second position. The second set of baffles 61 rotates toward the position of the rib 62. When it is about to rotate to the second position, the second set of baffles 61 starts to slide in contact with the rib 62 until the operating member 12 rotates to the second position. At this time, the rib 62 is just embedded in the second set of baffles 61, fixing the operating member 12 in this position. In other embodiments, the positioning assembly can also make other changes, such as swapping the positions of the baffles 61 and the rib 62, or replacing the rib 62 with a contact connected to an elastic member, so that it bounces between multiple sets of baffles 61 when rotated. Similarly, the number of baffles 61 is not limited to two groups, and different fixed positions can be set as needed.

[0064] The track socket adapter of the present invention is provided with a positioning assembly 6 on the operating member 12 and the fixing plate 33. When the operating member 12 is rotated into position, the user is prompted and the position is fixed, thereby avoiding poor contact caused by incomplete rotation or accidental touch, thereby ensuring the safety of the adapter during use. Figure 5 、 7 As shown in Figures 9 and 9, one end of the grounding shaft 34 is connected to the fixed socket 31, and the other end extends out of the socket body. In this embodiment, a through hole 133 is provided in the center of the receiving groove 131, which passes through the connecting portion. The through hole 133 extends into the circular groove toward one end of the circular groove and is connected with the first threading hole 332. The other end is flush with the connecting portion 130 to divide the receiving groove 131 into two parts. The grounding shaft 34 is arranged in the through hole 133, one end passes through the first threading hole 332 and is electrically connected to the first socket, and the other end extends out of the socket body along the through hole 133.

[0065] like Figure 4 、 9As shown in Figures 13 and 14, the adapter of the track socket of this embodiment further includes a locking mechanism 4, which is disposed within the socket body and partially extends out of the socket body, for locking the socket body to the track 7. The locking mechanism 4 includes a locking member 41, a return spring 42, and an operating mechanism 44. A limiting structure 43 is provided within the socket body, and the locking member 41 and the return spring 42 are slidably disposed within the limiting structure 43. One end of the operating mechanism 44 extends out of the socket body, and the other end is connected to the locking member 41. The locking member 41 includes a hook 410 extending from the connection portion 130 along the receiving groove 131. Pressing the operating mechanism 44 drives the locking member to slide radially along the socket body within the limiting structure 43 and compress the return spring 42, causing the hook 410 to be received in the receiving groove.

[0066] Furthermore, the limiting structure 43 is provided on the base 13 around the through hole 133, and includes a mounting groove 132 and a limiting plate for limiting the movement trajectory of the locking member 41. There are two hooks 410, which are respectively located in the receiving grooves 131 on both sides of the through hole 133. A connecting plate 411 is provided between the two hooks 410, and an avoidance hole is provided in the middle of the connecting plate 411. The locking member 41 is sleeved on the portion of the through hole 133 extending into the disc groove through the avoidance hole. At this time, the connecting plate 411 is slidably provided in the limiting structure 43, and the return spring 42 is provided in the avoidance hole along the movement direction of the locking member 41, with its two ends respectively connected to the connecting plate 411 and the socket body; the connecting plate 411 is integrally formed with a contact portion 412, and the operating end of the operating mechanism 44 extends out of the socket body through the opening on the base 13, and the connecting end abuts against the contact portion 412;

[0067] Under normal circumstances, the return spring 42 is in a natural state and the locking piece 41 is in the initial position. At this time, the hook 410 extends out of the connecting part, and the side of the hook 410 facing the insertion direction of the adapter is a slope. When the adapter is inserted, the slope slides in contact with the track 7, and the locking piece 41 slides along the installation groove 132 on the limiting structure 43 to the unlocked position. The return spring 42 is compressed and the hook 410 retracts into the connecting part 130. When the adapter is installed in place, the position of the hook 410 corresponds to the locking groove opened on the track 7. The return spring 42 is released, and the locking piece 41 returns to the initial position so that the hook 410 extends out of the connecting part 130 and engages with the locking groove; when the adapter needs to be pulled out, the operating structure 44 is pressed to make the locking piece 41 slide to the unlocked position, the hook 410 disengages from the locking groove and retracts into the connecting part 130, and the adapter can be removed from the track 7.

[0068] In this embodiment, by providing a locking assembly 6 on the adapter, the adapter is more firmly connected to the track, thereby ensuring safe use.

[0069] Preferably, Figure 1As shown, the protruding part of the hook 410 is arranged in the same direction and on the same horizontal plane as the anti-foolproof block 51. At this time, the locking groove and the slide groove 52 coincide with each other, that is, the slide groove 52 is the locking groove that cooperates with the locking mechanism 4. In this way, the slide groove 52 cooperates with the anti-foolproof block 51 and the locking mechanism 4 at the same time, which plays a corresponding role, simplifies the structure, and reduces production costs.

[0070] Preferably, Figure 5 、 7 As shown in , and 9, the conductive component 3 also includes a placeholder 35, which is installed in the connecting portion 130. The shape of the placeholder 35 matches the internal space of the connecting portion 130, and grooves are provided at both ends to cooperate with the rotating contact member 32. The placeholder 35 and the rotating contact member 32 are assembled into the receiving groove 131 together, and the placeholder 35 fills the gap between the rotating contact member 32 and the receiving groove 131. It can be understood that when the anti-foolproof block 51 is set on the connecting body 321, the shape of the placeholder 35 also needs to be changed accordingly so that the anti-foolproof block 51 can be received in the receiving groove 131. Since the placeholder 35 and the receiving groove 131 are separately provided, during assembly, the rotating contact member 32 can be combined with the placeholder 35 first and assembled into the receiving groove 131 together, thereby reducing assembly difficulty and reducing costs.

[0071] Further, such as Figure 2-3 As shown in Figure 9, a receiving groove for accommodating the locking member 41 is provided on the placeholder 35. When the locking member 41 is in the initial position, the hook 410 extends out of the connecting portion 130 along the receiving groove. When the locking member 41 is in the unlocked position, the hook 410 is received into the receiving groove. In this embodiment, the receiving groove can play the role of the mounting groove 132 in the limiting structure 43. Since the placeholder 35 further limits the movable space of the locking mechanism 4, the locking mechanism 4 is not easily displaced in the non-operating state, thereby improving the stability of the connection between the adapter and the track.

[0072] Preferably, Figure 4 、 10 As shown, the socket body is also provided with an indicator light, which is installed between the panel 11 and the fixed disk 33. An indicator hole is opened at the corresponding position of the panel 11, and a wiring slot is opened on the fixed socket 31. The indicator light is electrically connected to the wiring slot on the fixed socket 31 through a wire. When the adapter is powered on, the indicator light lights up, and when the power is off, the indicator light goes out; preferably, it also includes a protection door assembly 2, which is arranged between the jack 111 and the fixed socket 31, and its position corresponds to the jack 111; the specific structures of the indicator light and the protection door assembly 2 can adopt existing technologies, aiming to meet the requirements of electrical safety, and are not described here one by one.
