Description

Technical Field

[0001] The present application relates to the technical field of track sockets, and in particular to a box-type power track and a track socket. Background Art

[0002] The box-type power track is a new type of socket product, which is used in conjunction with an adapter. The box-type power track and the adapter together constitute a track socket. The box-type power track is usually installed on a mounting surface such as a wall, table, or baseboard. A junction box is usually provided on the mounting surface. The box-type power track is installed at the open end of the junction box by means of fasteners such as screws, and the connection between the internal conductor of the box-type power track and the power supply is realized in the junction box. Since the junction box is usually an 86-type junction box, the box-type power track is also called an 86-type power track or an 86-type socket. The adapter can be detachably installed on the box-type power track and draws power from the box-type power track. A socket is provided on the adapter for electrical equipment to plug in and draw power.

[0003] The box-type power rail in the related art includes a bottom shell with an opening at one end and a panel covering the open end of the bottom shell. A conductive conductor is arranged in the bottom shell, and the conductive conductor is connected to a power source. The panel is sunken toward the bottom shell to form a sink for accommodating an adapter, and a panel rail opening is formed at the bottom of the sink for the adapter to pass through. When the box-type power rail is installed on a junction box, the bottom shell is placed in the junction box as a whole, and the panel completely covers the junction box. The adapter is inserted into the bottom shell through the panel rail opening, and the adapter and the box-type power rail are contacted and electrically conductive by rotating itself. At this time, the adapter is partially placed in the sink, and its end face is slightly convex from the panel surface, so that the user can rotate the adapter to make the power-taking arm of the adapter contact with the conductive conductor in the bottom shell.

[0004] Since there is a sink groove on the panel, after the adapter is pulled out from the cassette power track, the sink groove will be exposed in the use scenario. When the cassette power track is not used for a long time, dust will accumulate in the sink groove, affecting the insertion of the adapter into the sink groove, thereby affecting the use of the cassette power track.

[0036] The following is combined with Figure 1-11 This application is described in further detail.

[0037] The present application discloses a box-type power track and a track socket. In power consumption scenarios of industrial production, commercial office and life, a junction box is usually set at an installation location such as a wall, a table and a skirting. The box-type power track 100 is fixedly installed on the junction box by means of screw connection or clamping, and is electrically connected to the mains wire in the junction box, so that the box-type power track 100 is energized and in a standby state. Embodiment 1:

[0038] An embodiment of the present application provides a box-type power rail.

[0039] Reference Figure 1-Figure 4 A sunken box-type power rail 100 includes a shell 1, a conductive component 2 arranged in the shell 1, and a sinking component 3.

[0040] Reference Figure 1-Figure 4 The shell 1 includes a bottom shell 12 and a panel 13 snap-fitted with the bottom shell 12. The bottom shell 12 is an insulating barrel with a hollow interior and an open end. The material is preferably plastic. The cross-section of the bottom shell 12 along the axial direction is approximately circular, and the cavity inside it is formed as a bottom shell chamber 111. The bottom shell chamber 111 is approximately a cylindrical cavity. The bottom shell 12 is installed in the junction box by fasteners such as screws.

[0041] The panel 13 is a plastic plate. In the specific use scenario of the box-type power rail 100, the panel 13 is exposed to the outside, which plays the role of aesthetic decoration and shielding the bottom shell 12. The panel chamber 112 is opened through the center of the panel 13, and the panel chamber 112 is a disc cavity. When the panel 13 is buckled on the open end of the bottom shell 12, the panel chamber 112 is coaxially arranged with the bottom shell chamber 111. Therefore, the bottom shell chamber 111 and the panel chamber 112 constitute a complete shell chamber 11.

[0042] Reference Figure 3 and Figure 4 The conductive component 2 includes an insulating base 21 placed in the bottom shell chamber 111, at least two conductive conductors 22 and an insulating cover 23. The insulating base 21 is made of the same material as the bottom shell 12, preferably plastic. The insulating base 21 is a barrel with a hollow interior and an open end, and the cross section along the axial direction is approximately circular. It is integrally formed at the bottom of the bottom shell chamber 111, and is provided with a plurality of chambers for installing the conductive conductors 22.

[0043] Reference Figure 3 and Figure 4 , the number of the conductive conductors 22 is at least two, and in the embodiment of the present application, the number of the conductive conductors 22 is set to three, namely, the live conductor, the neutral conductor and the ground conductor, and any conductive conductor 22 is installed in the corresponding chamber opened in the insulating base 21. Any conductive conductor 22 includes a wiring portion and a conductive sheet portion, the wiring portion is used to connect to the mains wire, and the conductive sheet portion is used to electrically connect to the power receiving arm of the adapter 200. Figure 3 , Figure 4 The structures of the live conductor and the neutral conductor are the same, the connection part is a traditional terminal, the conductive sheet part is a clip-type structure, and the two are symmetrically arranged about the axis of the insulating base 21. The conductive sheet part of the ground conductor is a flat plate, and the ground contact of the adapter 200 contacts the flat plate.

[0044] In another possible implementation, the conductive sheet of the ground conductor may be a centrally protruding arc-shaped plate, a groove is provided at the center of the highest protruding point of the arc-shaped plate, and the groove corresponds to the ground contact of the adapter 200 inserted into the box-type power rail 100 .

[0045] The insulating cover 23 is a plastic plate, which is embedded in the open end of the insulating base 21 to cover the opening of the inner cavity of the insulating base 21, that is, to shield the conductive conductor 22. The insulating cover 23 is provided with a power-taking port 24, which is connected to the inner cavity of the insulating base 21, so that the power-taking arm of the adapter 200 passes through the power-taking port 24, thereby contacting and electrically connecting with the conductive conductor 22 in the insulating base 21.

[0046] Reference Figure 3 and Figure 4The sinking assembly 3 includes a sliding plate 32 slidably mounted in the shell chamber 11, at least one reset spring 33 and at least one safety door 10. The sliding plate 32 is a plastic plate, and its cross-sectional shape is the same as the cross-sectional shape of the panel chamber 112, both of which are disc-shaped, and its movement direction is along the axial direction of the shell chamber 11. A track opening 31 is provided on the sliding plate 32, and the track opening 31 is arranged corresponding to the power supply port 24. In the embodiment of the present application, the number of reset springs 33 is preferably 4, and one end of the same side of the four reset springs 33 is pressed against the end face of the safety door 10 close to the insulating cover 23, and the other end of the same side of the four reset springs 33 is pressed against the insulating cover 23, and the driving direction of the reset spring 33 is along the movement direction of the sliding plate 32 to drive the sliding plate 32 to reset. In order to improve the stability of the reset spring 33 in the cassette power track 100, a limiting guide 14 can also be set at the position where the insulating cover 23 and the safety door 10 abut against the reset spring 33. The limiting guide 14 is a circular groove structure in which a circular ring is integrally formed with the insulating cover 23. The limiting guide 14 is a cylindrical structure integrally formed with the safety door 10. One end of the reset spring 33 is placed in the circular groove formed by the limiting guide 14, and the other end is sleeved on the cylinder formed by the safety door 10 to prevent sliding displacement between the reset spring 33 and the insulating cover 23 or between the reset spring 33 and the safety door 10.

[0047] In another achievable manner, the ends of the four return springs 33 away from the sliding plate 32 may also be pressed against the bottom of the bottom shell chamber 111 .

[0048] Reference Figure 1 and Figure 2 In the initial state, the sliding plate 32 is placed in the panel chamber 112, and its end face is flush with the end face of the panel 13. Here, the end face is the face of the sliding plate 32 facing the outside of the use scene; when the adapter 200 is inserted into the box-type power rail 100 to draw power, the power-drawing arm of the adapter 200 first passes through the rail opening 31, and then further moves toward the bottom of the shell chamber 11. The main structure of the adapter 200 pushes the sliding plate 32 to move together until the sliding plate 32 fits with the conductive component 2. In this process, the power-drawing arm of the adapter 200 passes through the power-drawing port 24 and extends into the chamber of the insulating base 21, and the reset spring 33 is compressed to generate elastic potential energy. Then the adapter 200 is rotated, and the power-drawing arm of the adapter 200 contacts the conductive conductor 22 to draw power. At this time, the end face of the sliding plate 32 and the cavity wall of the shell chamber 11 form a sink 4, and part of the structure of the adapter 200 along the height direction is placed in the sink 4. After the adapter 200 is inserted into the box-type power rail 100 , the adapter 200 partially overlaps with the box-type power rail 100 , reducing the height of the adapter 200 protruding from the box-type power rail 100 and solving the space occupation problem of the adapter 200 in the box-type power rail 100 .

[0049] At least one first guide member 5 is integrally formed on the cavity wall of the bottom shell chamber 111, and at least one second guide member 6 is integrally formed on the sliding plate 32. The first guide members 5 and the second guide members 6 are arranged in a one-to-one correspondence. In the embodiment of the present application, the number of the first guide members 5 and the second guide members 6 is the same, and both are set to 4. The four first guide members 5 are symmetrically arranged about the axis center of the bottom shell chamber 111, and the four second guide members 6 are symmetrically arranged about the axis center of the sliding plate 32.

[0050] Reference Figure 3 and Figure 4 , one of the first guide member 5 and the second guide member 6 is a guide groove, and the other is a guide rod. In the embodiment of the present application, the first guide member 5 is a guide groove, which is formed by a convex ridge integrally formed on the wall of the bottom shell chamber 111. Two adjacent convex ridges are arranged in parallel and are not connected to each other, and a guide groove is formed between them. The cross-sectional shape of the guide groove is a convex shape. The guide rod slides through the guide groove, and the guiding direction of the guide groove is along the expansion and contraction direction of the reset spring 33. The second guide member 6 is a guide rod, and its overall shape is L-shaped, and the bent transverse portion of the L-shaped second guide member 6 is radially extended in the direction away from the center of the sliding plate 32, and the extended portion slides through the guide groove. During the displacement of the sliding plate 32 along the axial direction of the shell chamber 11, the second guide member 6 slides in the first guide member 5. The first guide member 5 guides the movement direction of the sliding plate 32 by limiting the movement path of the second guide member 6, thereby preventing the sliding plate 32 from rotating and improving the sliding stability of the sliding plate 32 in the shell chamber 11.

[0051] The end of any second guide member 6 that slides through the first guide member 5 is rotatably mounted with a roller 7, and the number of rollers 7 is the same as the number of second guide members 6 in the embodiment of the present application, both of which are set to 4. The outer walls of the rollers 7 respectively contact the groove walls of the guide groove-shaped second guide members 6. The rollers 7 convert the sliding friction between the first guide member 5 and the second guide member 6 into rolling friction during the movement of the sliding plate 32, thereby reducing the friction between the first guide member 5 and the second guide member 6, so that the sliding of the sliding plate 32 in the housing chamber 11 is smoother.

[0052] In another achievable manner, the first guide member 5 is a guide rod, and the second guide member 6 is a guide groove, that is, the first guide rod and the second guide rod are inverted. The ridge structure forming the guide groove is integrally formed on the end surface of the sliding plate 32 close to the conductive conductor 22, and the roller 7 is rotatably mounted on the first guide rod.

[0053] Reference Figure 3 and Figure 4The sliding plate 32 integrally extends outward toward the end surface of the conductive component 2 to form a limit piece 8. The cross-sectional diameter of the panel chamber 112 is smaller than the diameter of the panel 13 of the bottom shell chamber 111. The cross-sectional diameter of the panel chamber 112 is the same as the cross-sectional diameter of the sliding plate 32. The cross-sectional diameter of the bottom shell chamber is the same as the cross-sectional diameter of the sliding plate 32 plus the limit piece 8. When the sliding plate 32 slides in the shell chamber 11, the limit piece 8 follows the sliding plate 32 to slide in the bottom shell chamber 111. When the adapter 200 is pulled out of the cassette power rail 100, the sliding plate 32 moves toward the panel chamber 112 under the driving action of the return spring 33 until the limit piece 8 hits the panel 13. At this time, the sliding plate 32 is just placed in the panel chamber 112, so that the sliding plate 32 blocks the shell chamber 11. The limiting member 8 cooperates with the panel 13 to prevent the sliding plate 32 from being separated from the housing chamber 11 under the driving action of the return spring 33 .

[0054] Reference Figure 3 and Figure 4 The safety door 10 is placed on the side of the sliding plate 32 facing the conductive component 2. The number of the safety door 10 is set to at least one. In the embodiment of the present application, the number of the safety door 10 is set to two. The two safety doors 10 are arranged opposite to each other and the interference part is located at the track opening 31 to facilitate blocking the track opening 31.

[0055] Previously, the same applicant has filed a utility model patent application entitled "A cassette-type electric track 100 and track socket with a safety door 10 structure" with the National Patent Office, with the application number "202323280403.X". The device mainly uses the safety door 10 structure to block the track opening 31 of the cassette-type electric track 100. Specifically in the embodiments of the present application, all the contents of the above application regarding the safety door 10 structure are incorporated herein by reference.

[0056] Reference Figure 3 and Figure 4The safety door 10 includes a door seat 101 integrally formed on the sliding plate 32, a door panel 103 slidably mounted in the door seat 101, and a spring 102. The door seat 101 has a U-shaped cross section, and its opening faces the track opening 31, that is, the openings of the door seats 101 of the two safety doors 10 are arranged opposite to each other. The length of the guard plate on the side of the door seat 101 close to the sliding plate 32 is slightly shorter than the length of the guard plate on the side of the door seat 101 away from the sliding plate 32, so as to facilitate the retraction of the door panel 103 and limit the extreme retraction position of the door panel 103. Any safety door 10 includes a door seat 101, two springs 102 and a door panel 103. One end of the two springs 102 on the same side is pressed against the door panel 103, and the other end on the same side is pressed against the door seat 101. In order to improve the supporting effect of the springs 102 on the door panel 103, the two springs 102 can be placed as close to the two ends of the door panel 103 as possible, and the two springs 102 can be kept parallel to each other.

[0057] The safety door 10 blocks and covers the track opening 31 of the sliding plate 32, thereby reducing the risk of foreign objects entering the bottom shell chamber 111 along the track opening 31 in the use scenario of the box-type power track 100, reducing the interference of foreign objects on various components in the bottom shell chamber 111, and maintaining the functional stability of the box-type power track 100.

[0058] In the initial state, the door panels 103 of the two safety doors 10 are placed at the rail opening 31 to block the rail opening 31. When the adapter 200 is inserted into the box-type power rail 100, the power-collecting arm of the adapter 200 abuts against the safety door 10, and the safety door 10 retracts toward the door seat 101 to release the blockage of the rail opening 31, and then the power-collecting arm of the adapter 200 passes through the power-collecting port 24 and extends into the conductive component 2 to collect power.

[0059] The implementation principle of Example 1 is as follows: in the initial state, the cassette power rail 100 is in a standby state without the adapter 200 inserted. At this time, the end surface of the sliding plate 32 of the sinking component 3 is flush with the end surface of the panel 13, and the safety door 10 simultaneously blocks the rail opening 31 on the sliding plate 32 to prevent external foreign matter from entering the shell chamber 11. Then, the adapter 200 is inserted into the box-type power rail 100. The adapter 200 first contacts the safety door 10, causing the safety door 10 to open, until the power-taking arm of the adapter 200 completely passes through the rail opening 31; the adapter 200 pushes the sliding plate 32 to move toward the bottom of the housing chamber 11 until the sliding plate 32 contacts the conductive component 2, and the power-taking arm of the adapter 200 is inserted into the conductive component 2. The reset spring 33 is compressed, and the end surface of the sliding plate 32 and the cavity wall of the housing chamber 11 form a sink 4. The adapter 200 is partially placed in the sink 4, so that the adapter 200 partially overlaps with the box-type power rail 100, reducing the height of the adapter 200 inserted into the box-type power rail 100. At this time, the adapter 200 is embedded in the housing chamber 11, and the gap between its outer peripheral wall and the housing chamber 11 is very small or almost non-existent.

[0060] Then the adapter 200 is rotated, and the power-taking arm of the adapter 200 contacts the conductive conductor 22 in the conductive component 2, so that the adapter 200 is charged, and the electrical appliance can be inserted into the adapter 200 to take power. The adapter 200 and the conductive conductor 22 are locked and limited along the axis direction of the adapter 200 to prevent the adapter from being ejected from the housing chamber 11 by the sinking component 3.

[0061] The adapter 200 is rotated, the adapter 200 is released from contact with the conductive conductor 22, and the adapter 200 is turned into a power-off state.

[0062] Under its own elastic action, the return spring 33 pushes the sliding plate 32 to move in the direction away from the conductive component 2 until the sliding plate 32 is restored to be flush with the end surface of the panel 13. During this process, the adapter 200 is separated from the conductive component 2, and the sinking groove 4 gradually disappears; finally, the adapter 200 is pulled out from the track opening 31, and the safety door 10 is restored to the closed state of the track opening 31. By setting the sinking component 3, when the adapter 200 is inserted into the cassette power rail 100, the sinking component 3 sinks to form a sinking groove 4 to accommodate part of the adapter 200 and reduce the height of the adapter 200 after being inserted into the cassette power rail 100; when the adapter 200 is pulled out from the cassette power rail 100, the sinking groove 4 on the sinking component 3 disappears, preventing dust in the use scene from accumulating in the sinking groove 4, maintaining the smoothness of the insertion of the adapter 200 into the sinking groove 4, and improving the use experience of the cassette power rail 100. Embodiment 2:

[0063] A sunken box-type power rail 100, referring to Figure 5The structure of the box-type power rail 100 according to the second embodiment of the present application is substantially the same as the structure of the box-type power rail 100 according to the first embodiment of the present application, and the differences between the two are mainly described below.

[0064] In this embodiment, if Figure 5 The difference between the second embodiment and the first embodiment is that the sliding plate 32 is not provided with the stopper 8, and the first guide member 5 and / or the second guide member 6 are provided with an anti-slipping member 9, and the anti-slipping member 9 is a plastic plate or a plastic block. The purpose of the anti-slipping member 9 is the same as that of the stopper 8 in the first embodiment, and the role played in the embodiment of the present application is also the same, both of which are to prevent the sliding plate 32 from being detached in the housing chamber 11.

[0065] Since the sliding plate 32 does not need to be limited by the limiter 8, the cross-sectional diameter of the panel chamber 112 does not need to be smaller than the cross-sectional diameter of the bottom shell chamber 111. Preferably, the cross-sectional diameter of the panel chamber 112 is the same as the cross-sectional diameter of the bottom shell chamber 111.

[0066] In the embodiment of the present application, corresponding to a group of mutually cooperating first guide members 5 and second guide members 6, the number of anti-slip members 9 is set to two. When the first guide member 5 is a guide groove, the anti-slip member 9 is placed at the end of the first guide member 5 close to the sliding plate 32, and the anti-slip member 9 is arranged oppositely and integrally formed on the groove wall of the guide groove type first guide member 5. The limit position of the sliding plate 32 sliding in the housing chamber 11 in the direction away from the conductive component 2 is that the anti-slip member 9 contacts the roller 7 on the second guide member 6, and the end face of the sliding plate 32 is flush with the end face of the panel 13. It is worth noting that the anti-slip member 9 itself can undergo slight elastic deformation to facilitate the installation of the second guide member 6 in the first guide member 5.

[0067] In another achievable manner, corresponding to a set of mutually matching first guide member 5 and second guide member 6, the number of anti-slip members 9 is set to two, and when the second guide member 6 is a guide groove, the anti-slip member 9 is placed at the end of the second guide member 6 away from the sliding plate 32, and the anti-slip member 9 is integrally formed on the groove wall of the guide groove type second guide member 6. The limit position of the sliding plate 32 sliding in the housing chamber 11 in the direction away from the conductive component 2 is that the anti-slip member 9 contacts the roller 7 on the first guide member 5, and at this time, the end surface of the sliding plate 32 is flush with the end surface of the panel 13.

[0068] In another achievable manner, corresponding to a set of mutually cooperating first guide members 5 and second guide members 6, the number of anti-slip members 9 is set to two, which are respectively integrally formed at the end of the first guide member 5 close to the sliding plate 32 and the end of the second guide member 6 away from the sliding plate 32. In this case, regardless of the specific structure of the first guide member 5 and the second guide member 6, the anti-slip purpose of the anti-slip member 9 can be achieved. The limit position of the sliding plate 32 sliding in the housing chamber 11 in the direction away from the conductive component 2 is that the anti-slip member 9 on the first guide member 5 conflicts with the anti-slip member 9 on the second guide member 6, and at this time, the end face of the sliding plate 32 is flush with the end face of the panel 13.

[0069] The implementation principle of Example 2 is as follows: by arranging an anti-slipping member 9 on the first guide member 5 and / or the second guide member 6, utilizing the limiting cooperation between the anti-slipping member 9 and the roller 7, or the limiting cooperation between the anti-slipping member 9 on the first guide member 5 and the anti-slipping member 9 on the second guide member 6, the sliding plate 32 is limited to move to the extreme position in the shell chamber 11 in the direction close to the opening end of the shell chamber 11, and the sliding plate 32 is prevented from being detached in the shell chamber 11, so that when the cassette power rail 100 is in a standby state without the adapter 200 inserted, the end surface of the sliding plate 32 is always flush with the end surface of the panel 13. Embodiment 3:

[0070] A sunken box-type power rail 100, referring to Figure 6 The structure of the box-type power rail 100 according to the second embodiment of the present application is substantially the same as the structure of the box-type power rail 100 according to the first embodiment of the present application, and the differences between the two are mainly described below.

[0071] In this embodiment, if Figure 6 As shown, the difference between Example 3 and Example 1 is that the second guide member 6 is arranged on the door seat 101 of the safety door 10. Embodiment 4:

[0072] A sunken box-type power rail 100, referring to Figure 7 and Figure 8 The structure of the box-type power rail 100 according to the fourth embodiment of the present application is substantially the same as the structure of the box-type power rail 100 according to the first embodiment of the present application, and the differences between the two are mainly described below.

[0073] In this embodiment, if Figure 7 and Figure 8As shown, the difference between Example 4 and Example 1 is that the stopper 8 is integrated on the safety door 10, and the second guide member 6 is integrally formed on the stopper 8. The stopper 8 is a circular ring structure, which is integrally formed on the outer periphery of the safety door 10, and the sliding plate 32 is arranged on the side of the safety door 10 away from the shell chamber 11. In this way, a step structure is formed between the sliding plate 32 and the stopper 8. When the cassette power rail 100 is in the standby state, the sliding plate 32 is placed in the panel chamber 112, the safety door 10, the stopper 8 and the second guide member 6 are placed in the bottom shell chamber 111, and the stopper 8 is tightly limited to the end surface of the panel 13 facing the bottom shell 12.

[0074] The number of the return springs 33 in the sinking assembly 3 is set to 2, and the ends of the two return springs 33 away from the sliding plate 32 pass through the insulating cover 23 and press against the bottom of the insulating base 21. Since the bottom of the insulating base 21 is the same as the bottom of the bottom shell chamber 111, the return spring 33 can also be regarded as pressing against the bottom of the bottom shell chamber 111.

[0075] A limiting guide 14 is provided on the cavity wall of the bottom shell chamber 111 and the safety door 10. The limiting guide 14 provided on the bottom shell chamber 111 is a first sleeve, and the limiting wire member 14 provided on the door seat 101 of the safety door 10 is a second sleeve. The second sleeve is slidably inserted into the first sleeve, and the reset spring 33 is placed in the cavity formed by the first sleeve and the second sleeve. The sliding cooperation of the first sleeve and the second sleeve can play a guiding role for the first guide 5 and the second guide 6, and limit the reset spring 33 at the same time, which has the same function as the fixed groove, and because the first sleeve and the second sleeve completely wrap the reset spring 33, the limiting effect is better than that of the fixed groove. Embodiment 5:

[0076] A track socket, referring to Fig. 9 and Fig.10 , including the box-type power rail 100 described in Example 1 and an adapter 200 used in conjunction with the box-type power rail 100. The adapter 200 includes a power supply base and a power-taking arm rotatably matched with the power supply base, the power supply base is provided with a socket for supplying power to the electrical appliance, and the power-taking arm is used to be inserted into the wall socket 100 to take power.

[0077] In another achievable manner, the box-type power rail 100 described in Example 1 included in a rail socket of the present application may also be replaced by the box-type power rail 100 described in any one of Examples 2 to 4.

[0078] When the cassette power rail 100 is in a standby state without the adapter 200 inserted, the end face of the sinking component 3 is flush with the open end face of the shell 1, so that the cassette power rail 100 is flat as a whole, and there is no sinking groove 4 structure, and naturally there will be no problem of dust accumulation in the sinking groove 4; when the adapter 200 is inserted into the cassette power rail 100 until it is in contact with the conductive component 2 and electrically connected, the cassette power rail 100 is turned into a working state in which the adapter 200 is inserted, and the sinking component 3 moves toward the conductive component 2, and the end face of the sinking component 3 and the cavity wall of the shell chamber 11 form a sinking groove 4, which is used to accommodate part of the adapter 200, and the adapter 200 partially overlaps with the cassette power rail 100 along the height direction of its own axis, that is, part of the structure of the adapter 200 is still protruding from the cassette power rail 100, which improves the space occupation problem after the adapter 200 is installed in the cassette power rail 100; until the adapter 200 is pulled out from the cassette power rail 100, the cassette power rail 100 returns to the standby state. Embodiment 6:

[0079] A track socket, referring to Fig.11 The track socket structure of Example 6 of the present application is basically the same as the track socket structure of Example 5 of the present application, and the differences between the two are mainly described below.

[0080] In the embodiments of this application, refer to Fig.11 After the adapter 200 is inserted into the box-type power track 100, its entire structure is completely placed in the box-type power track 100, and the end surface of the adapter 200 is flush with the end surface of the panel 13 and forms a plane.

[0081] At this time, the method of inserting the adapter 200 into the cassette power rail is changed. First, insert the plug into the adapter 200, and then insert the adapter 200 into the cassette power rail 100. The plug and the adapter 200 push the sliding plate 32 to move toward the conductive component 2 until the adapter is completely placed in the sinking groove. Then, the adapter 200 is rotated by the plug so that the adapter 200 is in contact with the conductive component 2 and electrically connected, thereby achieving the connection between the adapter 200 and the cassette power rail 100. When the adapter 200 is pulled out of the cassette power rail 100, the adapter 100 is rotated in the opposite direction by the plug, and the adapter 100 is ejected by the sinking component 3, and then the adapter can be taken out.

[0082] The rotation of the adapter 200 after being fully inserted into the box-type power rail 100 can not only rely on the plug, but also use an insulating rotating member similar to the plug structure. The overall structure of the insulating rotating member is the same as that of the plug. The only difference between the two is that the insulating rotating member is made of insulating material.

[0083] The specific technical solution of the present application is described in detail above, but the present application is not limited to the above technical solution, and supplementary explanation is given below.

[0084] 1. In the above specific embodiment, when the cassette power rail 100 is in the standby state, the sliding plate 32 is not limited to being flush with the panel 13 and forming a plane. The sliding plate 32 can also be in a state of being slightly concave to the end surface of the panel 13, and the height difference between the two is preferably 1-5mm, so that when the rail socket is used, the adapter 200 is first introduced into the small groove formed by the sliding plate 32 and the panel cavity 112. The depth of the sink 4 structure generated by the height difference is shallow, and there will be no problem of dust accumulation.

[0085] 2. In the above specific embodiment, when the cassette power track 100 is in the standby state, the sliding plate 32 is not limited to being flush with the panel 13 and forming a plane. The sliding plate 32 can also be in a state of being slightly convex to the end surface of the panel 13, and the height difference between the two is preferably 1-5mm, so that when the track socket is used, the adapter 200 first contacts the sliding plate 32, which facilitates the power arm of the adapter 200 to pass through the track opening 31.

[0086] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
