TECHNICAL FIELD

[0001] The present application relates to the technical field of track socket, in particular to a track socket. BACKGROUND

[0002] As a new flexible power supply device, the track socket is composed of a power track and an adapter, the adapter can move along the power track and increase or decrease as needed, which greatly meets the diversified power demand of users. As a core component, the conductive structure design of the power taking end of the adapter directly affects the convenience, safety and stability of use.

[0003] In the prior art, the power taking end of the adapter is usually provided with two conductive sheets corresponding to the N-pole and L-pole power taking sheets in the power track. In order to realize contact and separation, the two conductive sheets are designed to rotate reversely relative to the guide member of the adapter, that is, from the two side walls of the guide member, an included angle is formed by expanding outward and facing opposite directions, and when taking power, they are respectively popped out to the side of each side to contact the power taking sheets, and when not taking power, they are reversely rotated and parallelly stored. For details, refer to the contents described in the Chinese invention patent with the publication number CN116391301B.

[0035] The features of the present application and other related features are further described in detail by the following examples, so as to facilitate the understanding of the skilled in the art:

[0036] For the convenience of description and understanding, the description related to the position relationship such as front, back, up, down, left, right, outer, inner and the like in the present application shall refer to the orientation shown in the drawings.

[0037] The power track 200 provided by the present application is mainly suitable for power tracks with wider power connection ports and adapters adapted thereto, that is, the power track 200 provided by the present application is improved in structure in order to better cooperate with the adapter 100 for stable connection, especially in order to highlight the structural cooperation between the first conductive part 4 of the adapter 100 for power taking by turning over and the power taking piece 2A of the power track 200.

[0038] As shown in the drawings, the adapter 100 of the present application is mainly composed of a first conductive part 4 and a second conductive part 6. Figures 1 to 15As shown, the track socket provided in the case includes a power track 200 and at least one adapter 100 pluggable to the power track 200, the power track 200 includes a track main body 201, the track main body 201 is provided with a power taking port 1A, the track main body 201 is provided with two power taking sheets 2A, the two power taking sheets 2A are symmetrically arranged on both sides of the power taking port 1A. Specifically, the two power taking sheets 2A are inwardly inclined, and the two power taking sheets 2A are in the shape of a splayed whole, so as to be more convenient and fast to abut against the first conductive body 4 of the adapter 100 to form an electrical connection. The power taking sheet 2A is used as a conductive component, which contacts the conductive structure in the adapter 100 after the adapter 100 is inserted, and supplies power to the adapter 100. The symmetric arrangement ensures the stability and conductivity of the contact with the adapter 100, and ensures the reliability of power transmission. Among them, the existing power track is generally a cuboid, which is relatively long to realize the installation of multiple adapters and provide more socket ports. Generally includes track main body, i.e. shell, power taking sheet, insulating support and junction box and other components. The track main body, power taking sheet, insulating support and other structures are also adapted to be set in a long strip shape with a relatively long length. Such long strip design is well known in the art and will not be described here. The adapter 100 includes a socket end 101 and a power taking end 102 connected to the lower end of the socket end 101, and the socket end 101 includes a rotating ring 1. The socket end 101 further includes a connecting seat 2 connected to the lower end of the rotating ring 1, and the rotating ring 1 is a component for providing rotating operation for users, and the connecting seat 2 is used to support and install the internal components of the adapter. In order to facilitate production and ensure a certain rigidity, the rotating ring 1 is an integral structure, and the connecting seat 2 is also an integral structure. The power taking end 102 includes a guide body 3 connected to the lower end of the connecting seat 2, the guide body 3 is designed in a long strip shape, which is used to insert the power track 200 and electrically connected to the power track 200, and also provides a guide function. The connecting seat 2 and the rotating ring 1 are rotatably connected to ensure that the rotating ring 1 can rotate relative to the connecting seat 2, and realize the linkage operation described later.

[0039] The first conductive pieces 4 are rotatably connected to the connecting seat 2 through the linkage mechanism 5 and are arranged on the left and right sides of the guide body 3. The first conductive pieces 4 are used to realize electrical connection with the power track 200. It can be understood that the two first conductive pieces 4 are N-pole conductive pieces and L-pole conductive pieces, respectively, corresponding to the N-pole and L-pole power taking pieces in the power track. There are two first conductive pieces, which are arranged on the left and right sides of the guide body. It can be understood that the linkage mechanism 5 is also designed with two corresponding parts. Similarly, the subsequent parts corresponding to the conductive pieces and the linkage mechanism 5, and the parts having a connection relationship, should be two or two groups of matched parts. In the specific implementation, the two first conductive pieces 4 can be arranged in the middle of the conductive body in the common axisymmetric manner of the prior art, or can be arranged at the front and rear ends of the guide body in the central symmetric manner. In this case, the central symmetric manner is preferably used to arrange the two first conductive pieces. That is, the two first conductive pieces are arranged at the front and rear ends of the guide body on the left and right sides. It can be understood that at this time, the linkage mechanism 5 should also be arranged in the axisymmetric manner. Compared with the power taking manner of the prior art, the edge power taking is realized, which can make the power taking part of the adapter occupy less space, the structure is more compact, and the overall volume is small, which is beneficial to the miniaturization.

[0040] Turning the rotary ring 1 can drive the linkage mechanism 5 to act, thereby driving the first conductive member 4 to unfold / store relative to the guide body 3. When the first conductive member 4 is unfolded, it is in contact with the power supply track 200 and is conductive. When it is stored, the circuit is disconnected. When the rotary ring 1 is turned in one direction to drive the linkage mechanism 5 to act, the first conductive member 4 on the left and right sides can be driven to flip upward and unfold outside the side wall of the guide body 3 at the same time, and after the first conductive member 4 is unfolded, the lower end is parallel to the bottom of the power supply track 200, and the upper end is buckled on the power supply track 200. When the rotary ring 1 is turned in the other direction to drive the linkage mechanism 5 to act, the first conductive member 4 on the left and right ends can be driven to flip downward and store in the side wall of the guide body 3 at the same time. It can be understood that the rotation direction can be set in advance, and preferably, the rotation direction of the rotary ring 1 when the first conductive member 4 is unfolded relative to the guide body 3 is set to clockwise rotation, which is more in line with human use habits. Conversely, when the first conductive member 4 needs to be stored, the rotary ring 1 is rotated counterclockwise. In this case, preferably, the angle of the first conductive member 4 flipping upward is 90 degrees. That is, the movement mode of the first conductive member 4 is to unfold outward from the side wall of the guide body 3 and flip upward by 90 degrees, and the movement direction and opening direction of the two first conductive members 4 are the same. According to the above, it can be understood that the movement trajectory, ejection direction, opening direction and unfolding angle of the first conductive members on both sides of the guide body are the same, to ensure the stability of the power connection. The structure of the adapter in this case changes the movement trajectory and rotation direction of the first conductive member 4 by setting the linkage mechanism. The movement trajectory of the upward flipping only occupies the longitudinal space, and cooperates with the edge power supply design to significantly reduce the transverse size of the guide body, so that the overall volume of the adapter is smaller, and the area in the middle of the guide body can be left empty for other functions, such as wiring and weight reduction, to improve space utilization. This synchronous flipping ensures that the conductive members on both sides contact the power supply track at the same time, effectively ensuring the stability and synchronization of the electrical connection. When the first conductive member is in the storage state, it is hidden in the guide body, avoiding the risk of short circuit caused by foreign matter intrusion. Compared with the traditional adapter, the rotary operation is more labor-saving through the linkage mechanism, and the damping feeling provides clear in-place feedback, and the stability is better. The flipping movement of the first conductive member is consistent with the insertion direction of the guide body, and the insertion process is smooth and stable, more convenient and more synchronous. Avoid interference and reduce operation difficulty

[0041] In particular, with reference to Figures 1-7As shown, the linkage mechanism 5 of the case includes a driving arm 51 hinged to the upper end of the connecting seat 2, and a first spring 52 connected to the lower end of the driving arm 51. The other end of the driving arm 51 is hinged to the first conductive piece 4. When the first conductive piece 4 unfolds the power collecting piece to contact the power rail, the elastic force of the first spring 52 is converted into contact pressure through the driving arm 51, so that the first conductive piece and the power collecting piece are stably attached. Compared with the traditional rigid structure, this elastic contact can automatically compensate for the tolerance or deformation of the rail, ensure the stability of the contact resistance, and avoid heating and sparking caused by looseness. Through the synergistic effect of the driving arm and the spring, only two core components are needed to realize the power transmission and reset function, and the complex gear set or cam linkage mechanism in the prior art is omitted. This minimalist design reduces the matching error between parts, improves the overall stability, and reduces the production and maintenance costs.

[0042] Continuing to refer to Figures 1-7 As shown, further, a bracket 21 for connecting the driving arm 51 is provided on the upper wall surface of the connecting seat 2. The driving arm 51 includes a first connecting shaft 511 and a first connecting arm 512, and the two ends of the first connecting shaft 511 are hinged to the bracket 21. The bracket 21 provides a rigid rotating reference for the driving arm 51, ensuring that the axis position of the first connecting shaft 511 is fixed, and avoiding deviation caused by unstable support when the driving arm 51 swings. It should be noted that in specific implementation, the driving arm 51 is integrally formed, and the distinction between the labels and the components is only for the convenience of description and understanding. A second through hole 23 is provided on the connecting seat 2 for connecting the driving arm 51 and the first conductive piece 4, so as to facilitate the hinging of the driving arm 51 and the first conductive piece 4, and provide a connection position for the two. At the same time, the second through hole 23 can avoid the driving arm 51 and the first conductive piece 4 when the linkage mechanism 5 is moving, preventing interference with their movement. The first connecting arm 512 includes a downwardly bent first connecting portion 5121, and the first connecting portion 5121 is provided with a movable hole 5122. The first conductive piece 4 includes a second connecting shaft 41, and the second connecting shaft 41 is movably hinged in the movable hole 5122. For details, see Figure 7 As shown, the first connecting portion 5121 is bent downward, with an arc-shaped transition and no right angle. The movable hole 5122 is long strip-shaped, with its length direction consistent with the extension direction of the connecting portion, and the edge of the movable hole 5122 is chamfered. The curved shape of the first connecting portion 5121 matches the flipping trajectory of the first conductive piece 4, and when the first conductive piece 4 is flipped upward by the downward pressure of the first connecting portion 5121, the second connecting shaft 41 will also rotate. The provision of the movable hole 5122 allows the second connecting shaft 41 to slide in the hole along the length direction, so as to compensate for the positional deviation during movement and avoid rigid jamming. The arc-shaped transition of the first connecting portion 5121 reduces stress concentration and prolongs the service life of the connecting portion; and the flexible matching of the movable hole 5122 solves the jamming problem caused by the mismatch of the movement trajectory in the traditional rigid hinging, making the flipping of the conductive piece more smooth and stable.

[0043] When the first conductive piece 4 needs to be opened, the rotating ring is rotated to push the driving arm 51 to swing outward on the support 21 around the first connecting shaft 511; the first connecting part 5121 of the driving arm 51 swings downward to provide a downward pressure, at the same time, the movable hole 5122 pulls the first conductive piece 4 through the second connecting shaft 41; the second connecting shaft 41 slides along the hole length direction, the first conductive piece 4 is pressed downward and pulled inward at the same time to flip upward, at the same time, the second connecting shaft 41 slightly slides in the movable hole 5122 to adapt to the track, so as to finally make the first conductive piece 4 flip upward and open.

[0044] Continuing to refer to Figures 1-7 Further, the driving part 11 is arranged on the inner wall of the rotating ring 1 and covers the support 21, the driving part 11 includes the limiting groove 111 and the first baffle 112 symmetrically arranged on both sides of the limiting groove 111. The driving arm 51 further includes the swing arm 513 connected to the lower end of the first connecting shaft 511, and the convex 5131 is arranged on both sides of the swing arm 513 and matched with the first baffles 112 on both sides. The connecting seat 2 is concave downward and has the groove 26 with a wide upper part and a narrow lower part, the first spring 52 is arranged in the groove 26, and the upper end of the groove 26 is communicated with the limiting groove 111. As described above, the limiting groove 111 provides the swing space for the support 21 and the swing arm 512 to avoid movement interference; at the same time, the limiting groove 111 provides the installation and avoidance space for the first connecting shaft 511 to make it cooperate with the rotating ring 1. The first baffles 112 on both sides of the limiting groove 111 transmit the rotating force of the rotating ring 1 to the swing arm through the contact with the convex 5131 of the swing arm 513, and limit the maximum swing angle of the swing arm 513. In specific implementation, the convex 5131 is arranged as a semispherical convex, the convex 5131 is the force transmission node of the driving arm 51 and the driving part 11, the convex 5131 can be in contact with the wall surface of the first baffle 112 when the swing arm swings to receive the driving force of the rotating ring; at the same time, the contact between the convex 5131 and the first baffle 112 can provide clear operation feedback and jamming feeling to prompt the user that the stroke is in place.

[0045] In the prior art, the driving part of the rotating ring directly drives the actuating member, i.e. the driving arm. The actuating member is directly connected to the conductive sheet through a spring, and then the actuating member directly drives the conductive sheet through the spring. The disadvantage of this structure is that the conductive sheet will immediately move when the rotating ring rotates, and it cannot achieve a close abutting and rebounding effect. It is necessary to forcibly squeeze the rotating ring to a certain position, so the connection between the rotating ring 1 and the connecting seat 2 is generally designed to be loose, and the rotation is not smooth, and it cannot be designed to be more stable and closely matched. When the rotating ring 1 rotates to the limit position, the first conductive member 4 is prone to poor contact with the power track. After the conductive spring is popped out, the rotating ring 1 and the connecting seat 2 reach the maximum angle and are limited together. The spring direct connection or gear connection method mentioned in the background art has this problem

[0046] At the same time, when the power contact of the conductive sheet is connected to the power track, the taking sheet may be welded, and the two may be high-temperature fused and welded together. If only relying on the spring and the connection structure in the prior art, the conductive sheet may not be able to automatically reset and disconnect the power, which also leads to difficulty in pulling out the adapter. Because the contacts of the conductive sheet and the taking sheet of the power track are in contact with each other, they will be electrified, and the electric spark will be electrified. At this time, the temperature is as high as 3000 degrees, and the contacted metal will temporarily melt and cool down and fix. The conductive sheet of the adapter and the taking sheet of the power track are fused together, which causes the two to be stuck together and difficult or impossible to separate.

[0047] The structure in the case, the first spring 52 is connected to the swing arm 513 at the upper end and is arranged in the groove 26 at the lower end, so that the first spring 52 is limited in the groove 26 which is wide at the upper end and narrow at the lower end, and is limited in the third through hole 23. At this time, the first spring 52 is in a curved state under the cooperation of various structures. For details, see Figure 6As shown, the upper end of the first spring 52 abuts against the first baffle 112 on one side, and the lower end abuts against the groove wall surface of the groove 26, always maintaining a potential elastic force. In the normal state, the first spring 52 is always in a curved state. That is to say, the first spring 52 is in a curved state regardless of whether the first conducting member 4 is in the unfolded position or the storage position, only the bending direction is different. When the rotary ring 1 is rotated, the first spring 52 is first pushed to act, and then the driving arm 51 is pushed to act. In the initial stage of pushing the first spring 52, the action of the first conducting member 4 is not affected. That is to say, unlike the prior art, the first conducting member 4 cannot be stopped and directly opened when the rotary ring 1 is rotated. The present case has a gradual advancing process. With the rotation of the rotary ring 1, the first baffle 112 on one side first drives the first spring 52 in a curved state to act. When the rotary ring 1 is rotated to a certain extent, that is, with the rotation of the swing arm 513, when the protrusion 5131 on one side touches the wall surface of the first baffle 112, the first spring 52 rebounds from the bending state towards one side to the bending state towards the other side. The rebound of the first spring 52 changes the bending direction, thereby driving the first connecting arm 512 to act to move the first conducting member 4 to switch the unfolded / storage state of the first conducting member. In this way, when the first conducting member 4 is in the unfolded state, the rotary ring 1 is rotated to be stored, the driving arm 51 is pushed to act, and with the rotation of the rotary ring 1, the first baffle 112 on one side first drives the first spring 52 in a curved state to act. When the rotary ring 1 is rotated to a certain extent, with the rotation of the swing arm 513, when the protrusion 5131 on the other side touches the wall surface of the first baffle 112, that is, after the first spring 52 is actuated to a certain extent, the driving arm 51 directly actuates the first conducting member 4 to directly provide a forced actuation action, so that the first conducting member 4 can be opened during welding. Through the design of the protrusions 5131 at both ends, combined with the swing arm 513, the first spring 52, and the groove 26 with a wide upper part and a narrow lower part, and the cooperation of the above structures, the first conducting member 4 is effectively prevented from being stuck with the power track power piece, and good touch feeling is provided. When the rotary ring 1 is twisted to a certain extent, the first conducting member 4 can be unfolded / stored. In addition, the connection between the rotary ring 1 and the connecting seat 2 is more secure, and the rotation is smoother. After the rotary ring 1 is rotated to a certain angle, it can be automatically rotated and opened relative to the connecting seat 2, and the operation is more convenient.

[0048] Further, with reference to Figures 1-7As shown, the first conductive bushing 6 is installed on the connecting seat 2, and the first conductive bushing 6 includes a conductive connecting frame 61 connected to the lower end thereof and penetrating the connecting seat 2 downward. The first conductive bushing 6 serves as a fixed conductive node, which provides rotational support for the first conductive member 4 through the conductive connecting frame 61 and conducts the received current to the bushing body and finally to the plug. The support of the connecting seat 2 to the connecting frame ensures the stability of the rotation of the first conductive member 4 and reduces the occurrence of poor contact. The first conductive member 4 includes a middle shaft 42 connected to the right side of the second connecting shaft 41 and a second connecting arm 43 connected to the right side of the middle shaft 42. The middle shaft 42 serves as a rotational axis, allowing the first conductive member 4 to be flipped therearound; the second connecting arm 43 positions the power contact 44 to an appropriate height to ensure contact with the power rail power taking piece, and simultaneously serves as a conductive bridge connecting the power contact 44 and the middle shaft 42. In specific implementation, the second connecting arm 43 is a hook-shaped upward bending. The middle shaft 42 of the first conductive member 4 is rotationally connected to the conductive connecting frame 61, and the power contact 44 is arranged upward on the second connecting arm 43 to facilitate electrical connection with the power taking piece of the power rail.

[0049] As shown in Figure 8 , fourth through holes 31 and receiving grooves 32 are respectively provided on the two side walls of the guide body 3 for the first conductive member 4 to penetrate out and pass through, respectively. When the two first conductive members 4 are respectively received in the corresponding side of the receiving groove 32, the two first conductive members 4 are respectively embedded in the corresponding side of the receiving groove 32 and do not protrude from the side wall of the guide body 3. The fourth through hole 31 provides a movable passage for the first conductive member 4 when rotating relative to the side wall of the guide body to avoid interference. The first conductive member 4 is received so that the first conductive member 4 is entirely hidden in the side wall of the guide body.

[0050] As shown in Figures 1-6 , Figure 8 , Figure 9 , further, the adapter of the present case also includes an E pole conductive spring 7 and a driving member 8 for cooperating with the rotating ring 1 to drive the E pole conductive spring 7 to move. The E pole conductive spring 7 is used to connect with the ground conductive piece of the power rail to ensure the safety of electricity use. Rotating the rotating ring 1 can simultaneously drive the first conductive member 4 and the E pole conductive spring 7 to unfold / be received relative to one side of the left and right sides of the guide body 3. The first conductive member 4 and the E pole conductive spring 7, that is, the N / L pole and the E pole, realize synchronous and reliable connection and disconnection, which not only ensures the safety of electricity use but also improves the convenience of use. An E pole conductive bushing 71 is also installed on the connecting seat 2, and the upper end of the E pole conductive spring 7 penetrates the connecting seat 2 upward and is connected to the E pole conductive bushing 71, and the lower end extends into the guide body 3. The E pole conductive bushing 71 serves as a fixed contact point to connect the E pole pin of the power plug and conducts the current to the ground conductive piece of the power rail through the E pole conductive spring 7. The E pole conductive bushing 71 and the E pole conductive spring 7 are integrally formed.

[0051] The conventional power rail, because of its narrow power taking port, the E pole conductive sheet for grounding is generally fixedly arranged on the power rail at the bottom position in the middle of the power taking port, and the E pole conductive sheet of the matching adapter is hard and is also arranged at the bottom of the guide body and is fixed at the bottom and cannot be extended. Such structure makes the adapter be able to touch the grounding conductive bushing on the power rail when being inserted, although such use is more convenient, but foreign matters are easy to invade from the power taking port and cause the grounding conductive bushing to be stuck and cause the E pole conductive sheet to be inserted invalid. In addition, such connection mode is easy to cause the E pole conductive sheet and the grounding conductive bushing to be seriously worn and cause the E pole conductive sheet and the grounding conductive bushing to be loose, contact badly and contact invalid, and there is a big safety hidden danger. When the adapter is not used, it is also more troublesome to be stored alone, and the exposed E pole conductive sheet is easy to be accidentally damaged and is also easy to cause the user to be scratched. The side edge extendable E pole conductive sheet 7 of the case is convenient for connecting power taking and effectively solves the above problems and has the advantages of being convenient for storage, being beneficial to the protection of the E pole conductive sheet 7 and preventing wear and tear. It can be understood that when the E pole conductive sheet 7 of the adapter of the case is equipped, the corresponding grounding conductive bushing or conductive sheet of the matching power rail should also be arranged at the corresponding position of one side or both sides of the power taking port of the power rail, because the grounding conductive bushing or conductive sheet is arranged at the side edge and is wrapped by the power rail and is also not easy to be invaded by foreign matters, so that the stability of power taking is ensured.

[0052] In addition, in the face of the power rail of this type with a large hollow power taking port opening, it is difficult to find the contact position of the E pole conductive sheet, and at the same time, the invasion of foreign matters and safety should also be ensured, so the structure of the side edge extendable E pole conductive sheet 7 of the case is convenient for connection with the power rail, stable connection and convenient use.

[0053] Continuing to refer to Figures 1-6 , Figure 8 , Figure 9 , specifically, the driving piece 8 is an integral structure, the driving piece 8 includes a rotating shaft 81, a driving rod 82 connected to the upper end of the rotating shaft 81 and a top block 83 connected to the lower end of the rotating shaft 81. The E pole conductive sheet 7 includes a contact sheet 72, and the sidewall of the guide body 3 is provided with a sixth through hole 33 for the contact sheet 72 to pass out. The rotating shaft 81 serves as the rotation center of the driving piece 8, and through the rotation of the two end third connecting shafts 811 on the connecting column, the swing of the driving rod 82 is converted into the circular motion of the top block 83, so that the top block 83 can press or loosen the contact sheet 72.

[0054] The connecting seat 2 comprises a fifth through hole 24 for the driving rod 82 to pass through, and the inner side wall of the rotating ring 1 is provided with a second baffle 12, two second baffles 12 are symmetrically arranged on both sides of the rotating shaft 81, and a limiting space 121 for the driving rod 82 to move is formed between the two second baffles 12. The driving rod 82 is an intermediate force transmission between the rotating ring 1 and the rotating shaft 81. When the rotating ring 1 rotates, the second baffle 12 pushes the driving rod 82 to swing in the limiting space, and in turn drives the rotating shaft 81 to rotate, so that the top block 83 presses or loosens the contact piece 72. The limiting space 121 limits the maximum swing angle of the driving rod 82, avoiding excessive rotation to cause structural damage and unstable expansion / storage of the contact piece 72.

[0055] The driving member 8 is rotatably connected between the guide body 3 and the connecting seat 2 through the rotating shaft 81, the connecting seat 2 is provided with a first connecting column 25, the bottom inner wall of the guide body 3 is provided with a second connecting column 34, and the rotating shaft 81 comprises a third connecting shaft 811 arranged at both ends thereof, and the third connecting shaft 811 at both ends is rotatably connected to the first connecting column 25 and the second connecting column 34, respectively. In specific implementation, the first connecting column 25 and the second connecting column 34 are both provided with a connecting hole for the third connecting shaft 811 to insert, and the connecting hole provides a support point for the rotating shaft to rotate. The double-point support of the first connecting column 25 and the second connecting column 34 makes the rotating shaft 81 rotate without deviation, avoiding the misalignment of the top block 83 and the contact piece 72. The close rotating cooperation between the connecting hole and the third connecting shaft 811 ensures smooth rotation without jamming. When the top block 83 rotates with the rotating shaft 81, the front end extrudes the contact piece 72, so that the contact piece 72 overcomes its own elastic force, passes through the sixth through hole 33 of the side wall of the guide body and is connected with the grounding conductive piece of the power rail; when the rotating shaft 81 rotates reversely, the top block releases the extrusion on the contact piece 72 and separates from the contact piece, the contact piece 72 is retracted by its own elastic force and hidden in the sixth through hole 33, and does not protrude from the side wall of the guide body 3, ensuring that the contact piece is completely hidden in the side wall of the guide body when it is stored, effectively preventing external factors from damaging the contact piece 72, and facilitating the storage of the adapter.

[0056] Further, with reference to Figures 1-6 、 Figure 8 、 Figure 10As shown, the adapter 100 of the present application further comprises a buckle structure 9 for firmly mounting the adapter 100 on the power rail 200 and ensuring the stability of the connection between the two. Specifically, the buckle structure 9 comprises a first clamping block 91 and a second clamping block 92 that can be extended / contracted relative to the side wall of the guide body 3, a button 93 for simultaneously driving the first clamping block 91 and the second clamping block 92 to extend relative to the side wall of the guide body 3, and a reset member 94 for driving the first clamping block 91 and the second clamping block 92 to contract relative to the side wall of the guide body 3. The first clamping block 91 and the second clamping block 92 are respectively used for clamping the two sides of the power supply track 200. The first clamping block 91 and the second clamping block 92 are symmetrically arranged, which ensures the consistency and stability of clamping. The button 93 is exposed on the outer circumferential wall of the connecting seat 2 to facilitate the pressing operation of the user. The seventh through hole 35 is respectively provided on the two side walls of the guide body 3 for the first clamping block 91 and the second clamping block 92 to pass through. The seventh through hole 35 provides a precise extension / contraction channel for the first clamping block 91 and the second clamping block 92 and limits the movement direction of the first clamping block 91 and the second clamping block 92 to be only horizontal extension / contraction along the side wall of the guide body 3. In specific implementation, for the convenience of production and manufacturing and clamping, the size and structure of the first clamping block 91 and the second clamping block 92 are the same, and the size and structure of the two seventh through holes 35 are also the same. The reset member 94 provides a continuous pushing force for the extension of the first clamping block 91 and the second clamping block 92, ensuring that the clamping block can automatically pop out and lock after the adapter 100 is inserted into the power rail 200.

[0057] With reference to the foregoing Figures 1-6 , Figure 8 , Figure 10As shown, this is the preferred embodiment of the buckle structure 9 of the present application. In this embodiment, the buckle structure 9 further comprises a Z-shaped linkage rod 901 and a hook-shaped linkage rod 902. The first clamping block 91 and the button 93 are integrally formed on the Z-shaped linkage rod 901, and the second clamping block 92 is integrally formed on the hook-shaped linkage rod 902. The integrally formed structure of the Z-shaped linkage rod 901 and the hook-shaped linkage rod 902 reduces the number of parts, avoids the action delay caused by assembly gap, and is beneficial to reduce production cost and facilitate disassembly. The Z-shaped structure of the Z-shaped linkage rod 901 uses the principle of leverage to amplify the pressing force, making the operation more labor-saving. The hook-shaped linkage rod 902 as a driven linkage rod converts the pushing force of the Z-shaped linkage rod into the retracting action of the second clamping block 92, and at the same time receives the rebounding pushing force of the reset member 94 to drive the second clamping block 92 to extend. The hook-shaped linkage rod 902 comprises a straight rod 9021, a bent hook portion 9022 connected to the lower end of the straight rod 9021, and a fourth connecting shaft 9023 arranged between the two. The hook-shaped linkage rod 902 is hinged to the guide body 3 through the fourth connecting shaft 9023, and the second clamping block 92 is arranged on the straight rod 9021. The straight rod 9021 abuts against the connecting seat 2 through the reset member 94, and the bent hook portion 9022 is bent inward and abuts against the Z-shaped linkage rod 901. In specific implementation, the reset member 94 is a spring, which is called the second spring in the present application for convenience.

[0058] As described above, the first clamping block 91, the second clamping block 92, and the reset member 94 cooperatively form a lever structure that is interconnected, specifically, the Z-shaped linkage rod 901, the hook-shaped linkage rod 902, and the spring cooperatively form a lever structure that is interconnected. The user presses the button inward by hand, one end of the Z-shaped linkage rod 901 abuts against the bent hook portion 9022, the hook-shaped linkage rod 902 rotates through the fourth connecting shaft 9023, the straight rod 9021 is compressed inward toward the fixed seat, and the first clamping block 91 and the button 93 are integrally formed on the Z-shaped linkage rod 901, while the second clamping block 92 is integrally formed on the straight rod 9021, so the first clamping block 91 and the second clamping block 92 are retracted at the same time. When the user releases the button 93, the straight rod 9021 is driven to rotate outward under the elastic force of the spring, the bent hook portion 9022 is driven to move inward, the Z-shaped linkage rod 901 is pushed outward, and then the first clamping block 91 and the second clamping block 92 are simultaneously extended outward from the guide body 3 to lock the power rail. The cooperation of the Z-shaped linkage rod 901 and the hook-shaped linkage rod 902 forms a stable linkage lever structure, ensuring that the first clamping block 91 and the second clamping block 92 are synchronously extended and retracted, significantly improving the operation convenience and locking stability of the buckle structure 9.

[0059] Specifically as Figure 1As shown. It should be noted that the power supply track on the market, the power connection port is generally narrow, such as the patent shown in the figure with the publication number CN2023209729473. Because this kind of power supply track, the power connection port is wider, dust or foreign matter is easy to enter. Of course, it can also be adapted to the power connection port mentioned in the background art. As Figure 1 、 Figures 11-15 The application provides a power supply track with a protection door, a protection door 3A is arranged at the lower end of the power taking sheet 2A, and the protection door 3A is rotationally connected to the inner side wall 2011 of the track main body 201. Under normal circumstances, the protection door 3A will shield the power taking sheet 2A, and play a protection role. The protection door 3A is connected to the track main body 201 in a rotationally connected manner, and is opened and closed through rotary motion, which reduces the structural complexity, reduces the space occupation, reduces the risk of jamming, and can effectively play a protection role. A reset member 4A is arranged between the protection door 3A and the track main body 201. By arranging the reset member 4A, the protection door 3A can be automatically reset after the adapter 100 is pulled out, and returned to the position of shielding the power taking sheet 2A. Without manual operation, the automatic reset of the protection door 3A is realized, so that the power taking sheet 2A can be shielded in time after the adapter 100 is pulled out, and the protection effect is continuously played. Compared with the prior art, the structure is simplified, and the failure probability is reduced.

[0060] A power taking space 202 is formed between the power taking sheet 2A and the protection door 3A, and the power taking space 202 is formed between the power taking sheet 2A and the protection door 3A, and the size changes with the rotation of the protection door 3A. In order to provide space for the adapter 100 to contact the power taking sheet 2A after being inserted, it is ensured that the adapter 100 can smoothly take power. The dynamic change of the size of the power taking space 202 adapts to the insertion and pulling-out process of the adapter 100, so that enough space is ensured for the adapter 100 to contact the power taking sheet 2A when the adapter 100 is inserted, and the space is closed after being pulled out to play a protection role.

[0061] An avoiding space 203 for avoiding the protection door 3A is formed between the protection door 3A and the track main body 201, and the avoiding space 203 is formed between the protection door 3A and the track main body 201, and provides a containing space for the rotation of the protection door 3A. When the protection door 3A is pressed downward and rotated by the adapter 100, collision between the protection door 3A and other structures in the track main body 201 is avoided, and it is ensured that the protection door 3A can be smoothly rotated to completely leave the power taking port 1A. It is ensured that the rotation of the protection door 3A is not hindered, so that the adapter 100 can be smoothly inserted. Compared with the space required for transverse movement in the prior art, the avoiding space is more space-saving in the transverse direction, which is beneficial to the miniaturization of the power supply track. Under normal circumstances, one end of the protection door 3A is exposed to the power taking port 1A to close the power taking space 202 and prevent foreign matter from entering.

[0062] When the adapter 100 is inserted from the power taking opening 1A, the protection door 3A is pressed down by the adapter 100, rotates downward and gradually approaches the inner side wall 2011 of the track body 201, until it is completely away from the power taking opening 1A, at this time, the power taking space 202 gradually increases and opens; when the adapter 100 is pulled out of the power taking opening 1A, the protection door 3A is automatically reset under the action of the reset member 4A, gradually rotates upward and approaches the power taking opening 1A, until the power taking sheet 2A is shielded, at this time, the power taking space 202 gradually decreases until it is closed.

[0063] It should be noted that, in order to match the structure of the power track with a relatively long length, the protection door is provided with a plurality of protection doors along the length direction of the power taking opening. When the adapter is inserted, the number of protection doors corresponding to the adapter pressing and rotating is N, wherein N is a positive integer, N can be 1, or a value in the range of 2 to 10, and of course can be a value greater than 10. In this case, preferably, when the adapter is inserted, the number of protection doors corresponding to the adapter pressing and rotating is 6. The meaning of the described protection door rotating downward and gradually approaching the inner side wall 2011 of the track body 201 until it is completely away from the power taking opening 1A is that the protection door is retracted into the two sides of the power taking opening of the track body 201, and it is no longer exposed to the power taking, and no longer interferes with the adapter 100.

[0064] The protection door of this structure can effectively prevent foreign matter from entering the power taking space, thereby preventing the occurrence of poor contact, and can improve safety and prevent the user from accidentally touching the power taking sheet. This design makes the space design of the power track smaller, saves design space, and makes the power track narrower and smaller, facilitating installation and transportation. On the one hand, it improves safety and effectively prevents the user from being electrocuted when inserting the adapter, and on the other hand, it effectively prevents foreign matter from entering and affecting the electrical connection of the power track. It can be understood that the avoidance space is used to avoid the protection door when it rotates, preventing interference with the protection door. As the size of the power taking space changes with the rotation of the protection door, the size of the avoidance space also changes. The power taking sheet is completely shielded by the protection door, thereby separating the space between the power taking opening 1A and the power taking sheet 2A. That is, the protection door is blocked between the power taking opening 1A and the power taking sheet 2A, thereby completely closing the power taking space.

[0065] Continuing to refer to Figures 1-5As shown, preferably, the protection door 3A comprises an upwardly curved arc-shaped connecting arm 31A rotatably connected with the track body 201, a shielding portion 32A connected to the other end of the arc-shaped connecting arm 31A, and a third baffle 33A connected to the lower end of the shielding portion 32A. The arc-shaped design of the arc-shaped connecting arm 31A can reduce the space occupation during rotation, and at the same time, disperse the pressure when the adapter is inserted, so as to avoid stress concentration and breakage, and improve the structural strength. The roof-shaped structure of the shielding portion 32A enhances the shielding sealing property, and is more easy to guide the insertion direction of the adapter than the flat structure. The limiting cooperation of the shielding portion 32A and the first protrusion 204 precisely controls the rotation stroke, so as to avoid structural damage caused by excessive rotation of the protection door. The structure of the shielding portion 32A determines the opening and closing degree of the power taking space 202, and together with the first protrusion 204, forms the guiding and limiting of the adapter. The baffle can isolate the power taking port 1A and the avoiding space 2031 in the normal state, so as to prevent foreign matters from entering the avoiding groove; when the protection door is rotated, the baffle is inserted into the avoiding groove and abuts against the side wall to realize the secondary limiting. The baffle is doubly isolated by the power taking port and the avoiding space, and the avoiding space and the inside of the track, so as to reduce the risk of foreign matter jamming; the secondary limiting further ensures the stability of the rotation stroke of the protection door, and avoids excessive movement. The first protrusion 204 is arranged on the inner wall of the bottom of the track body 201 and extends upwardly, and cooperates with the shielding portion 32A to limit the rotation lower limit of the shielding portion 32A, and at the same time, provides a guide for the insertion of the adapter, so as to ensure the accurate butt joint of the adapter with the power taking sheet 2A. The first protrusion 204 cooperates with the shielding portion 32A to form the primary limiting, and the height of the first protrusion 204 determines the maximum rotation angle of the protection door, and at the same time, together with the third baffle 33A and the avoiding groove 2031, forms a space constraint system. The avoiding space 203 comprises an avoiding groove 2031 for the insertion of the third baffle 33A. The avoiding groove 2031 provides a containing space for the rotation of the third baffle 33A, and at the same time, cooperates with the third baffle 33A through the groove wall to strengthen the limiting, so as to directionally contain the third baffle 33A, and avoid the collision between the baffle and other structures inside the track body during rotation; the closed design reduces the dust accumulation and the probability of jamming. The avoiding groove is the terminal point of the movement track of the third baffle 33A, and the position and depth of the avoiding groove directly affect the rotation smoothness and limiting precision of the protection door.

[0066] For the convenience of understanding and description, referring to Figure 3 , Figure 4 As shown, this is the normal state of the power track, that is, the state when the adapter 100 is not inserted. The shielding portion 32A has a roof shape, and the front end thereof extends toward the middle of the power taking port. When the adapter is not inserted, the shielding portion separates the space between the power taking port 1A and the power taking sheet 2A. That is, the shielding portion blocks between the power taking port 1A and the power taking sheet 2A, and completely closes the power taking space. The third baffle 33A extends downwardly to the upper end of the first protrusion 204, and cooperates with the first protrusion 204 to separate the power taking port from the inside of the track body.

[0067] The shielding part of the protection door in this case can effectively prevent foreign matter from entering the power taking space when the adapter is not inserted, thereby preventing poor contact and improving safety and preventing the user from accidentally touching the power taking sheet. In addition, the baffle separates the avoidance space from the power taking port, thereby effectively preventing foreign matter from entering the avoidance space and preventing the foreign matter from being stuck in the avoidance space, thereby preventing the protection door from being stuck and unable to drive the protection door to rotate when the adapter is inserted, improving safety and stability.

[0068] With the insertion of the adapter 100 from the power taking port 1A, the adapter 100 is pressed against the shielding part, thereby driving the entire protection door to rotate downward. With the rotation of the protection door, the shielding part is finally limited to abut against the upper end of the convex strip, and the wall surface on the side of the power taking port is abutted against the side wall of the convex strip. The third baffle 33A is finally completely inserted into the avoidance slot and abutted against the side wall of the track main body 201. At this time, the power taking space 202 is opened and gradually increased, and the power taking is completed. Through the limiting cooperation of the shielding part and the first convex strip 204, the downward rotation of the protection door is effectively limited. Again, through the cooperation of the third baffle 33A and the side wall of the track main body, double limiting cooperation is achieved. At the same time, with the complete insertion of the adapter 100, the shielding part is completely withdrawn from the power taking port in the vertical direction and is abutted and cooperated with the first convex strip 204. The setting of the first convex strip 204 plays a role in guiding and limiting the adapter insertion and finally fixing the limiting position. In addition, as described above, with the complete insertion of the adapter 100, the shielding part of the protection door is completely withdrawn from the power taking port in the vertical direction after complete rotation and is limited to abut against the first convex strip 204. At the same time, the baffle is finally completely inserted into the avoidance slot and abutted against the side wall of the track main body 201. Through the limiting cooperation of the two, the adapter is accurately avoided when the adapter is inserted into the power taking port. The adapter designed in this way does not need to be designed to avoid space specifically because the protection door has been accurately and limitedly shrunk into the track main body. On the one hand, it can effectively prevent the adapter from being stuck by the protection door. This design makes the space design of the power track smaller, saves design space, and makes the power track narrower and smaller, which is convenient for installation and transportation.

[0069] Continuing to refer to Figures 1-5As shown, further, in the present embodiment, the power rail also includes a first fixing seat 5A connected to the inner side wall 2011 of the rail body 201, the first fixing seat 5A is detachably connected with the rail body 201, and the power taking sheet 2A is detachably connected to the first fixing seat 5A. Through the rigid support of the first fixing seat 5A, the power taking sheet 2A is accurately positioned and firmly fixed, avoiding loosening of the power taking sheet due to vibration and deformation caused by long-term plugging and unplugging of the adapter, and ensuring that the conductive contacts of the power taking sheet and the adapter are always in stable contact. In addition, through the detachable design of the rail body and the power taking sheet, the production and assembly can be installed step by step (first install the fixing seat, then install the power taking sheet), reducing the assembly difficulty; when maintaining, the fixing seat can be separately disassembled to replace the power taking sheet or the protection door, without the need to disassemble the entire rail body; when transporting, the package can be disassembled, reducing the occupied space. The upper end of the protection door 3A abuts against the first fixing seat 5A to close the power taking space 202. The abutting cooperation of the protection door 3A and the first fixing seat 5A fills the gap between the power taking sheet and the inner side wall of the rail body, further blocking the entry of dust, water vapor and other foreign matters into the power taking space, and cooperating with the shielding part 32A and the third baffle 33A to form better protection effect, better safety and stability.

[0070] With reference to the foregoing description Figures 1-5 As shown, further, the inner side wall of the rail body 201 is provided with a first clamping groove 205, a second clamping groove 206 and a second protrusion 207. The first fixing seat 5A includes a third protrusion 51A fitted into the first clamping groove 205, a fourth protrusion 52A fitted into the second clamping groove 206, and a third clamping groove 53A for the second protrusion 207 to be clamped into.

[0071] The present case, through the cooperation of multiple clamping and limiting, connects and fixes the first fixing seat. Compared with single clamping groove or screw fixing, multiple clamping forms constraint from three directions, so that even in the case of long-term plugging and unplugging of the adapter, the first fixing seat will not be offset, ensuring the stable contact position of the power taking sheet 2A and the adapter, and reducing the risk of poor contact. When installing, only the first fixing seat needs to be aligned with the rail body and a pushing force is applied to complete the clamping; when disassembling, a reverse pulling force is applied to separate, which greatly improves the efficiency of production and assembly and later maintenance. This structure realizes locking through its own shape, without the need for additional fasteners, reducing the weight and cost of parts.

[0072] Further, the fourth clamping groove 54A and the fifth clamping groove 55A are arranged on the first fixing seat 5A, and the left and right ends of the power taking sheet 2A are clamped into the fourth clamping groove 54A and the fifth clamping groove 55A respectively. Through the fourth clamping groove 54A and the fifth clamping groove 55A, the power taking sheet 2A is clamped on the first fixing seat, the shaking caused by external force is limited, and the initial consistency between the two symmetrical power taking sheets is ensured. Because the power taking sheet is easily bent slightly under the pressure of adapter plugging for a long time, the fourth clamping groove 54A and the fifth clamping groove 55A support the power taking sheet from both ends and disperse the stress to the first fixing seat, which can effectively avoid the deformation of the power taking sheet caused by excessive local stress. At the same time, the design of this clamping structure is convenient to disassemble and assemble, which effectively reduces the maintenance cost.

[0073] Preferably, the first fixing seat 5A is made of PVC material. PVC material has excellent electrical insulation performance, high volume resistivity, and large dielectric strength, which can reliably isolate the conductor from the external structure, effectively prevent electric leakage or short circuit, and ensure the safety of power use. Whether it is hard or soft PVC, it is easy to be molded by injection molding, extrusion and other processes, and is suitable for various structural parts such as adapter track shell, insulation lining, sealing element, etc., which is suitable for large-scale batch production and significantly reduces the manufacturing cost. It has good weather resistance and protection, can resist dust and water vapor intrusion, and protect the internal conductive parts. Among them, soft PVC can also act as a sealing gasket or flexible connecting piece by virtue of its flexibility, filling the gap and adapting to slight deformation during installation, and adapting to special scenarios such as flexible tracks. The cost advantage is outstanding, the raw material price is low, and it can meet the economic needs of civil and commercial power tracks. In this case, the PVC material is preferably soft PVC, which better interferes with the power taking sheet and the track body to better interfere with the connection and achieve good sealing effect.

[0074] Further, in the present embodiment, the inner side wall 2011 of the track body 201 is provided with a connecting groove 208, the second fixing seat 6A is clamped in the connecting groove 208, the protective door 3A is hinged to the upper end of the second fixing seat 6A, and the reset member 4A is a torsion spring connected between the second fixing seat 6A and the protective door 3A. The second fixing seat 6A corresponds to an intermediate adapter, which separates the hinge point of the protective door from the inner side wall of the track body. Compared with directly hinging on the track body, the rotation of the protective door may be stuck due to the curvature and flatness of the inner side wall. The second fixing seat can be accurately machined by a mold to have a hinge shaft and a mounting surface, so that the rotation shaft of the protective door is straighter and the stress is more uniform, and the rotation of the protective door will not be interfered by the slight deformation of the track body. The size of the second fixing seat 6A can be customized according to the rotation track of the protective door, such as the thickness and height which are just suitable for the connecting groove 208, so as to avoid protruding from the inner wall and occupying additional space when directly installed on the inner side wall of the track body, so that the avoiding space 203 of the protective door during rotation can be designed to be smaller, and the track body is indirectly narrower. Through the clamping of the connecting groove 208 and the second fixing seat 6A, the protective door and the fixing seat can be taken out separately without disassembling the track body. When the protective door is worn out and the torsion spring is invalid, the second fixing seat can be directly pulled out for replacement, which is convenient for maintenance.

[0075] In summary, the second fixing seat is added to make the rotation of the protective door 3A smoother and without interference, to ensure the stability of the rotation of the protective door, and to facilitate the reduction of space design. At the same time, the clamping of the second fixing seat and the connecting groove of the inner side wall of the track body realizes the detachable connection of the protective door, which is convenient for production, disassembly, maintenance and transportation.

[0076] Preferably, the protective door 3A is made of plastic material. The protective door on the market is usually a soft rubber sealing strip which is easily deformed under pressure. After a long time of use, such protective door will produce plastic deformation and collapse, so as to lose the sealing effect. Especially when applied in a kitchen environment with oil fume and salt, the above situation is more likely to occur. Moreover, the above protective door will be hardened in the environment with oil fume and salt, which will affect the insertion, pulling out and movement along the track of the adapter. The material of the protective door of the present application is plastic, which has the characteristics of good contact, not easy to age and not easy to deform, so as to prolong the service life of the power track and enhance the user experience.

[0077] Preferably, the track body 201 of the present application is oval, which has a smoother inner wall transition and more economical design space compared with the traditional rectangular design, so as to facilitate the miniaturization and lightness of the overall structure.

[0078] In some embodiments, a grounding conductive sheet is arranged on both sides or one side of the power supply track 200 at the power outlet 201, for contacting the E pole conductive spring 7. When the adapter 100 is inserted into the power outlet 201, rotating the rotary ring 1 can simultaneously drive the first conductive members 4 at both ends to flip up and abut against the power supply sheets 2A on both sides, thereby achieving electrical connection between the adapter 100 and the track 200. At the same time, the contact sheet 72 of the E pole conductive spring 7 of the adapter 100 is popped out to abut against the grounding conductive sheet in the power supply track 200, and the two are connected. At the same time, the first clamping block 91 and the second clamping block 92 on both sides of the adapter 100 are clamped into the power supply track 200 from both sides of the power outlet 201, thereby achieving the limiting and anti-disengagement of the adapter 100.

[0079] In a specific implementation, the track body 201 includes an outer shell 201A and an inner frame 201B, the inner frame 201B is used to fit and install various components, and the outer shell 201A is used to cover the inner frame 201B and other internally installed components. The connecting lug 201C is connected and fixed on the inner wall surface of the outer shell 201A by welding, and the outer shell 201A and the inner frame 201B are connected and fixed by screws through the connecting lug 201C. That is, screw holes are formed on the connecting lug 201C, and corresponding screw holes are also formed on the wall surface of the inner frame 201B.

[0080] As described above, the present application protects a track socket, and all technical solutions identical or similar to the present application shall be deemed to fall within the protection scope of the present application.
