[0067] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0068] The terms used in the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and are not intended to limit the present disclosure.

[0069] The track socket is a movable socket, including an adapter 01 and a power track 02. The adapter can be installed at different positions of the power track to obtain power. Fig.11 , the adapter 01 includes an adapter body 1, a guide body 2 and a power-taking arm 3. The adapter body 1 has a plug-in surface 101, and the plug-in surface 101 is used for inserting the plug of the electrical appliance. The guide body 2 is used to extend into the interior of the power rail 02, and the guide body 2 is provided with a receiving groove 21. The power-taking arm 3 is located in the receiving groove 21, and can be unfolded or stored relative to the guide body 2. When the power-taking arm 3 is unfolded, it can contact the conductive bar 022 in the power rail 02, so that the adapter is in a powered-on state. In the related art, the receiving groove 21 is usually provided on the side of the guide body 2 away from the plug-in surface. When the user moves the electrical appliance, the electrical appliance may involve the plug wire, thereby driving the plug and the adapter body 1 to move. In this process, the power-taking arm 3 may follow the adapter body 1 to move along the direction of the plug-in surface 101, so that the power-taking arm 3 is separated from the conductive bar 022, resulting in poor contact between the adapter 01 and the power rail 02.

[0070] To solve the above problems, the present disclosure provides an adapter 01, such as Figure 1 As shown, the adapter 01 includes an adapter body 1 , a guide body 2 and a power extraction arm 3 .

[0071] The adapter body 1 is the main body of the adapter 01, and is used to connect the plug of the electrical appliance and to supply power to the electrical appliance. The adapter body 1 has a plug-in surface 101, on which a two-hole jack and a three-hole jack are provided for adapting to different types of plugs.

[0072] The guide body 2 is a component of the adapter 01 for inserting into the power rail 02. The guide body 2 has a plate-like structure. The guide body 2 and the plug-in surface 101 can be arranged in parallel. The guide body 2 is located on the side of the adapter body 1 away from the plug-in surface 101 and is connected to the adapter body 1. There is a gap 10 between the guide body 2 and the adapter body 1, and the gap 10 is used to accommodate the first shell wall 0211 of the power rail 02, see Figure 1 , the first shell wall 0211 is the side wall where the strip opening 0214 is not. That is, the adapter 01 is a side-plug adapter, and when the adapter 01 is assembled to the power rail 02, the orientation of the plug-in surface 101 is different from the orientation of the strip opening 0214. The guide body 2 has a receiving groove 21, and the receiving groove 21 is used to accommodate the power taking arm 3. Specifically, the first wall surface 201 of the guide body 2 is provided with the receiving groove 21, and the first wall surface 201 is the wall surface of the guide body 2 close to the plug-in surface 101, that is, the first wall surface 201 is the wall surface of the guide body 2 located in the gap 10, and the notch of the receiving groove 21 is located in the gap 10. The receiving groove 21 can include multiple parts. Of course, the receiving groove 21 can also be a through groove structure, that is, the receiving groove 21 passes through the first wall surface 201 and the second wall surface 202 of the guide body 2, and the second wall surface 202 is the wall surface of the guide body 2 away from the plug-in surface 101. It is not difficult to understand that when the receiving groove 21 includes multiple parts, the receiving groove 21 can be partially a through groove structure and the remaining part can be a blind groove structure. The specific structure of the receiving groove 21 will be described in detail below.

[0073] Among them, the power taking arm 3 is the power taking component in the adapter 01, and the power taking arm 3 is arranged in the receiving groove 21 and is connected to the guide body 2. At least part of the power taking arm 3 can extend out of the receiving groove 21 to reach the above-mentioned gap 10, so as to contact the conductive bar 022 fixed to the first shell wall 0211 in the power rail 02. Specifically, the power taking arm 3 can be rotatably connected to the guide body 2. When the power taking arm 3 rotates along the first circumferential direction, the power taking arm 3 gradually extends into the gap 10. When the power taking arm 3 rotates along the second circumferential direction, the power taking arm 3 gradually retracts into the receiving groove 21. The second circumferential direction is the opposite of the first circumferential direction. It is easy to understand that the first circumferential direction can be clockwise or counterclockwise. According to the different viewing angles of observing the rotation of the power taking arm 3, the rotation direction of the power taking arm 3 will also change, and the embodiments of the present disclosure do not limit this.

[0074] In practice, the adapter 01 is usually used in conjunction with the power rail 02, see Figure 1The power track 02 is provided with a strip opening 0214 for the guide body 2 to be inserted. The guide body 2 of the adapter 01 passes through the strip opening 0214 and extends into the interior of the power track 02. At this time, the first shell wall 0211 of the power track 02 is located in the gap 10 between the guide body 2 and the socket body 1, and a conductive bar 022 is fixed on the first shell wall 0211. The power taking arm 3 and the plug-in surface 101 are located on both sides of the conductive bar 022.

[0075] By adopting the technical solution provided by the embodiment of the present disclosure, there is a gap 10 between the adapter body 1 and the guide body 2, and the power taking arm 3 is arranged in the receiving groove 21 of the guide body 2. At least part of the power taking arm 3 can extend out of the receiving groove 21 to reach the gap 10 between the adapter body 1 and the guide body 2, thereby contacting the conductive bar 022. In this way, after the adapter 01 is assembled to the power rail 02, the power taking arm 3 and the plug-in surface 101 are located on both sides of the conductive bar 022. When the user moves the electrical appliance so that the power taking arm 3 follows the adapter body 1 and moves along the direction of the plug-in surface 101, the power taking arm 3 moves in the direction close to the conductive bar 022, so that the power taking arm 3 can contact the conductive bar 022 more closely, thereby avoiding poor contact between the adapter 01 and the power rail 02.

[0076] In some possible embodiments, the power taking arm 3 includes multiple parts.

[0077] like Figure 2 As shown, the power taking arm 3 includes a shaft body 31 and a contact arm 32. Correspondingly, the receiving slot 21 includes a first portion 211 and a second portion 212, and the first portion 211 and the second portion 212 are connected. Figure 2 The shaft body 31 is located in the first part 211, and the lower end of the shaft body 31 is rotatably connected to the guide body 2, and the upper end of the shaft body 31 is electrically connected to the functional components inside the adapter body 1. The contact arm 32 is located in the second part 212, one end of the contact arm 32 is connected to the outer wall of the shaft body 31 near the lower end, and the other end is suspended. The suspended end of the contact arm 32 can extend out of the second part 212 when the shaft body 31 rotates, referring to Figure 1 , the suspended end of the contact arm 32 extends out of the receiving groove 21 and enters the gap 10, that is, the suspended end of the contact arm 32 can extend into the gap 10 under the rotation of the shaft body 31. The suspended end of the contact arm 32 is used to contact the conductive bar 022. Further, the shaft body 31 is electrically connected to the contact arm 32, and the shaft body 31 is electrically connected to the functional components inside the adapter body 1. Therefore, when the suspended end of the contact arm 32 is in contact with the conductive bar 022, the power arm 3 can make the adapter body 1 in a powered-on state, thereby providing electrical energy to the electrical appliance.

[0078] In one example, see Figure 2The contact arm 32 has a plate-like structure, the shaft body 31 has a columnar structure, and the contact arm 32 is vertically arranged with the shaft body 31. Figure 3 , the first portion 211 and the second portion 212 of the accommodating groove 21 are vertically arranged.

[0079] In this way, when the shaft body 31 rotates, it is possible to ensure that the contact arm 32 moves in a plane perpendicular to the shaft body 31 , thereby preventing the contact arm 32 from moving in the axial direction of the shaft body 31 .

[0080] In one example, the outer sides of the shaft 31 and the contact arm 32 are wrapped with an insulating sleeve, which is easy to understand. Figure 2 As shown, the upper end of the shaft body 31 and the suspended end of the contact arm 32 are electrically connected to other components respectively, so the upper end of the shaft body 31 and the suspended end of the contact arm 32 are not wrapped by the insulating sleeve. In this way, the creepage distance between the power taking arm 3 and the guide body 2 can be increased.

[0081] In some examples, the guide body 2 has two receiving grooves 21 , and the adapter 01 includes two power extraction arms 3 .

[0082] like Figure 3 As shown, the guide body 2 has two receiving grooves 21, the first parts 211 of each receiving groove 21 are arranged at intervals, and the second parts of each receiving groove 21 extend in opposite directions. Figure 3 Each receiving groove 21 has a first portion 211 and a second portion 212, and each second portion 212 is connected to a first portion 211. The two first portions 211 are spaced apart, and the two second portions 212 extend in opposite directions, that is, the two second portions 212 extend in opposite directions.

[0083] Further, the two first parts 211 may be arranged in parallel, and each second part 212 may be arranged perpendicular to one first part 211 .

[0084] In this way, when the two power taking arms 3 are correspondingly installed in the two receiving grooves 21, the distance between the two shafts 31 is shorter. Accordingly, the components for driving the shafts 31 in the adapter body 1 can be arranged more compactly, taking advantage of the miniaturized design of the adapter 01.

[0085] In some examples, such as Figure 4 As shown, the first part 211 is connected to the second wall 202 of the guide body 2. The second wall 202 is the avoidance of the guide body 2 away from the plug-in surface 101. Further, the shaft body 31 is located in the first part 211 and is rotatably connected to the guide body 2. The outer wall of the shaft body 31 can be flush with the second wall 202.

[0086] In this way, the thickness of the guide body 2 can be reduced, and accordingly, the width of the strip-shaped opening 0214 can be reduced.

[0087] In some examples, the receiving groove 21 includes a first portion 211 and a second portion 212, the second portion 212 is disposed on the first wall surface 201 of the guide body 2, and the second portion 212 is a blind groove, that is, the second portion 212 is not connected to the second wall surface 202 of the guide body 2. The first portion 211 is located inside the guide body 2 and is connected to the side wall of the second portion 212, and the first portion 211 is not connected to the first wall surface 201 and the second wall surface 202 of the guide body 2.

[0088] In some examples, contact arm 32 includes two parts.

[0089] like Figure 5 As shown, the contact arm 32 includes a connecting portion 321 and a contact portion 322. The connecting portion 321 has a strip structure. One end of the connecting portion 321 is connected to the outer wall of the lower end of the shaft body 31. The other end of the connecting portion 321 has a mounting through hole 3211. The axis of the mounting through hole 3211 is perpendicular to the axis of the shaft body 31. The contact portion 322 includes a first cylindrical structure and a second cylindrical structure arranged coaxially. The first cylindrical structure and the second cylindrical structure are connected and have unequal outer diameters. The outer diameter of the first cylindrical structure is smaller. The first cylindrical structure is located in the mounting through hole 3211. The second cylindrical structure is located outside the mounting through hole 3211 and is located on the side of the connecting portion 321 close to the plug-in surface 101. The first cylindrical structure is used to contact the conductive strip 022.

[0090] Optionally, the first cylindrical structure and the mounting through hole 3211 may be interference fit.

[0091] Optionally, the side of the contact portion 322 close to the conductive strip 022 may be coated with a silver alloy. Specifically, the wall surface of the second cylindrical structure away from the first cylindrical structure may be coated with a silver alloy. In implementation, the contact portion 322 needs to frequently contact the conductive strip 022, and coating the contact surface with a silver alloy may make the contact portion 322 more wear-resistant, thereby increasing the service life of the power taking arm 3.

[0092] Optionally, the connecting portion 321 and the shaft body 31 may be integrally formed.

[0093] By adopting the technical solution provided in the embodiment of the present disclosure and configuring the contact arm 32 to be divided into two parts, the difficulty of processing the contact arm 32 can be reduced.

[0094] In some examples, such as Figure 2 As shown, the second portion 212 has an escape groove 2120 therein, and the escape groove 2120 is used to escape the suspended end of the contact arm 32 .

[0095] Specifically, the avoidance groove 2120 can be a circular groove. The avoidance groove 2120 only needs to ensure that the suspended end of the contact arm 32 does not contact the guide body 2. The shape and size of the avoidance groove 2120 are not limited in the embodiment of the present disclosure.

[0096] For the avoidance groove 2120, the technicians can set the groove depth according to actual needs. It is not difficult to understand that when the groove depth of the avoidance groove 2120 is deep, the avoidance groove 2120 can prevent the suspended end of the contact arm 32 from contacting the guide body 2. When the groove depth of the avoidance groove 2120 is shallow, although the avoidance groove 2120 cannot prevent the suspended end of the contact arm 32 from contacting the guide body 2, it can reduce the deformation of the guide body 2 caused by the impact of the contact arm 32 to a certain extent.

[0097] In the previous example, the contact arm 32 includes a connecting portion 321 and a contact portion 322. The first cylindrical structure of the contact portion 322 can extend out of the side of the mounting through hole 3211 close to the bottom of the second portion 212. In combination with this example, the avoidance groove 2120 is used to avoid the protruding portion of the contact portion 322 to prevent the contact portion 322 from contacting the guide body 2.

[0098] In some possible embodiments, the adapter body 1 includes a socket body 11 and a driving mechanism 12 .

[0099] like Figure 4 and Figure 6 As shown, the socket body 11 includes a base 111, a cover plate 112, a connector 113 and a mounting member 114. The base 111 and the cover plate 112 both have a circular plate structure. The base 111 and the cover plate 112 are arranged opposite to each other. The cover plate 112 has a plurality of connecting columns 1121 on one side close to the base 111. The ends of the connecting columns 1121 are provided with threaded holes. The base 111 has a plurality of connecting holes 1111. Each connecting hole 1111 is arranged opposite to a connecting column 1121. The base 111 and the cover plate 112 are fastened and connected by bolts. The base 111 has a plug-in slot 1112 on one side away from the cover plate 112. The connector 113 extends into the plug-in slot 1112 and is connected to the base 111. The driving mechanism 12 (only a part of the driving mechanism is shown in the figure) is located between the base 111 and the cover plate 112 and is sleeved outside the base 111.

[0100] Furthermore, if Figure 8 As shown, there is a clamping cavity 1130 below the connecting member 113, the mounting member 114 and the guide body 2 both have a plate-like structure, the mounting member 114 and the guide body 2 are vertically arranged, and the two form a similar L-shaped structure. The upper part of the mounting member 114 and the guide body 2 extends into the above-mentioned clamping cavity 1130 and is connected to the connecting member 113 respectively. Figure 7The guide body 2 is located on the side of the connecting member 113 away from the base 111 (not shown), and there is the above-mentioned gap 10 between the guide body 2 and the base 111. The driving mechanism 12 is transmission-connected to the power taking arm 3, and the driving mechanism 12 is used to drive the power taking arm 3 to extend into the gap 10.

[0101] For some examples, see Figure 6 and Figure 8 The edge of the guide body 2 has at least one installation avoidance groove 24, and each installation avoidance groove 24 is on the extension line of the axis of a connecting hole 1111.

[0102] In practice, the base 111 and the cover plate 112 are fastened together by bolts, and an installation avoidance groove 24 is provided on the edge of the guide body 2 to facilitate the screwing of the bolts, thereby improving the assembly convenience of the adapter 01.

[0103] For example, see Figure 6 and Figure 8 The cover plate 112 has three connecting posts 1121 on one side close to the base 111. The three connecting posts 1121 are distributed in a triangular shape, which can be an isosceles triangle or an equilateral triangle. Accordingly, the base 111 is provided with three connecting holes 1111, wherein the distances between the two connecting holes 1111 and the edge of the plug-in slot 1112 are equal. Figure 8 A mounting avoidance groove 24 is respectively arranged on the third wall surface and the fourth wall surface of the guide body 2 , and the two mounting avoidance grooves 24 are respectively arranged corresponding to the above-mentioned two connecting holes 1111 .

[0104] In some examples, the socket body 11 is snap-fitted to the guide body 2 .

[0105] like Figure 8 As shown, the guide body 2 and the mounting member 114 are connected to form an L-shaped plate structure, wherein the mounting member 114 extends into the clamping cavity 1130 of the connecting member 113, and the mounting member 114 is connected to the connecting member 113, and the guide body 2 is used to extend into the accommodating cavity 0215 of the power rail 02. The mounting member 114 is provided with a first clamping protrusion 1141, and correspondingly, the connecting member 113 has a first clamping groove 1131, and the first clamping groove 1131 cooperates with the first clamping protrusion 1141 to realize the clamping of the guide body 2 and the adapter body 1 in the first direction.

[0106] Furthermore, if Figure 4 As shown, a second engaging groove 23 is provided on the second wall surface 202 of the guide body 2. Figure 8As shown, the connecting member 113 has a snap-fitting cavity 1130, which is used to accommodate the upper end portion of the guide body 2 and the mounting member 114. A second snap-fitting protrusion 1132 is provided on the side wall of the snap-fitting cavity 1130 of the connecting member 113 away from the base 111. The second snap-fitting protrusion 1132 cooperates with the second snap-fitting groove 23 to realize the snap-fitting of the guide body 2 and the adapter body 1 in the second direction.

[0107] Among them, see Figure 6 The first direction is the direction from the base 111 to the cover 112, see Figure 4 , the second direction is the axial direction of the shaft body 31.

[0108] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0109] The embodiment of the present disclosure provides an adapter 01, in which a gap 10 is provided between the adapter body 1 and the guide body 2, and a power-collecting arm 3 is disposed in a receiving groove 21, and the receiving groove 21 is located on a side of the guide body 2 close to the plug-in surface 101, and the power-collecting arm 3 can extend into the gap 10 between the adapter body 1 and the guide body 2, thereby contacting the conductive bar 022. In this way, after the adapter 01 is assembled to the power rail 02, the power-collecting arm 3 and the plug-in surface 101 are located on both sides of the conductive bar 022, and when the user moves the electrical appliance so that the power-collecting arm 3 follows the adapter body 1 to move along the plug-in surface 101, the power-collecting arm 3 moves in a direction close to the conductive bar 022, so that the power-collecting arm 3 can contact the conductive bar 022 more closely, thereby avoiding poor contact between the adapter 01 and the power rail 02.

[0110] The present disclosure embodiment provides a power rail 02, such as Figure 1 As shown, the power rail 02 includes a housing 021 and a conductive bar 022 .

[0111] The housing 021 is a component for the conductive strip 022 in the power rail 02, and the housing 021 has a hollow cubic structure. Specifically, the housing 021 has a first housing wall 0211, a second housing wall 0212, and a third housing wall 0213. The first housing wall 0211 and the second housing wall 0212 are arranged opposite to each other, and the third housing wall 0213 is adjacent to the first housing wall 0211 and the second housing wall 0212, respectively.

[0112] Specifically, the second shell wall 0212 has a mounting surface 02121 for fixing and mounting the power rail 02, and the mounting surface 02121 is connected to the mounting position such as a wall or a desktop. The third shell wall 0213 has a strip opening 0214, and the strip opening 0214 is for inserting the guide body 2 of the adapter 01. The strip opening 0214 may be rectangular in shape, and the strip opening 0214 extends along the length direction of the shell 021. The first shell wall 0211, the second shell wall 0212 and the third shell wall 0213 are arranged to form a receiving cavity 0215. In practice, the power rail 02 is used in conjunction with the adapter 01, see Figure 1 After the adapter 01 and the power rail 02 are assembled, the first shell wall 0211 is located in the gap 10 between the guide body 2 of the adapter 01 and the adapter body 1 .

[0113] The housing 021 may be made of a metal material. Of course, the housing 021 may also be made of a non-metal material. The embodiment of the present disclosure does not limit the material of the housing 021. For example, the housing 021 may be made of a stainless steel material.

[0114] The conductive bar 022 is located in the accommodating cavity 0215 and fixed to the first shell wall 0211. When the adapter 01 is assembled to the power rail 02, the conductive bar 022 is located between the plug-in surface 101 of the adapter 01 and the power taking arm 3. It can be understood that the conductive bar 022 can be directly fixed to the shell 021 or indirectly fixed to the shell 021 through a component. There can be multiple conductive bars 022. When the power rail 02 includes multiple conductive bars 022, at least one conductive bar 022 is fixed to the first shell wall 0211, and the remaining conductive bars 022 can be fixed to the third shell wall 0213 or the fourth shell wall. The fourth shell wall is a shell wall in the shell 021 that is arranged opposite to the third shell wall 0213.

[0115] In some examples, the power rail 02 further includes a clamping member 024 , which is fixed to the first shell wall 0211 , and the conductive strip 022 is clamped to the clamping member 024 .

[0116] Specifically, see Fig.10 The first shell wall 0211 is provided with a plurality of connecting ribs 02111 on one side of the accommodating cavity 0215, and the clamping member 024 is clamped with the plurality of connecting ribs 02111. The clamping member 024 has two accommodating through grooves on the side away from the first shell wall 0211, see Figure 1The two receiving slots are arranged in sequence in the insertion direction of the guide body 2. The power rail 02 includes two conductive bars 022, each conductive bar 022 is installed in a receiving slot, and the two conductive bars 022 can be used as an L-pole conductive bar and an N-pole conductive bar, respectively, and are connected to the live wire and the neutral wire in the external power supply. Accordingly, each conductive bar 022 is in contact with a power-taking arm 3.

[0117] Furthermore, the power rail 02 further includes a third conductive bar 022 , which can be used as an E-pole conductor and is fixed to the first shell wall 0211 or the fourth shell wall of the shell 021 .

[0118] In some possible embodiments, the power rail 02 further includes an extension plate 023 .

[0119] like Figure 1 As shown, the extension plate 023 is located outside the accommodating cavity 0215 and on the side of the strip opening 0214 away from the first shell wall 0211 . The extension plate 023 is connected to the third shell wall 0213 of the shell 021 , and the extension plate is parallel to the insertion direction of the guide body 2 .

[0120] Specifically, see Fig.10 ( Fig.10 0213 is a schematic diagram of a detection test of a power rail shown in an embodiment of the present disclosure), the strip opening 0214 is located in the middle of the third shell wall 0213, and the edge of the strip opening 0214 divides the third shell wall 0213 into a first shell wall portion 02131 and a second shell wall portion 02132. The first shell wall portion 02131 is the portion between the edge of the strip opening 0214 and the second shell wall 0212, and the second shell wall portion 02132 is the portion between the edge of the strip opening 0214 and the first shell wall 0211.

[0121] like Fig.10 As shown in the left part, when the extension plate 023 is not provided on the power rail, after the probe enters the strip opening 0214, the movable angle of the probe is large and it is easy to contact the power rail, which means that the anti-electric shock performance of the power rail is poor. Fig.10 As shown in the right part, when the power rail is provided with an extension plate 023, after the probe enters the strip opening 0214, the movable angle of the probe is small and it is not easy to contact the power rail, which means that the power rail has a strong anti-electric shock performance.

[0122] For example, see Fig.10 A first edge of the top wall of the extension plate 023 close to the strip opening 0214 is coplanar with a second edge of the clamping member 024 close to the strip opening 0214 , and a plane formed by the first edge and the second edge does not intersect with the conductive strip 022 .

[0123] In some examples, such as Fig. 9 As shown, a surface of the extension plate 023 facing away from the first shell wall 0211 and the mounting surface 02121 are located in the same plane.

[0124] In this way, the installation stability of the power rail 02 fixed to the wall, desktop and other installation locations can be improved.

[0125] In some examples, the extension plate 023 is integrally formed with the housing 021 .

[0126] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0127] The embodiment of the present disclosure provides a power rail 02. For the power rail 02, when the adapter 01 is assembled to the power rail 02, the conductive bar 022 is located between the plug-in surface 101 of the adapter 01 and the power-taking arm 3. In this way, after the adapter 01 is assembled to the power rail 02, the power-taking arm 3 and the plug-in surface 101 are located on both sides of the conductive bar 022. When the user moves the electrical appliance so that the power-taking arm 3 follows the adapter body 1 and moves along the direction of the plug-in surface 101, the power-taking arm 3 moves in a direction close to the conductive bar 022, so that the power-taking arm 3 can be in closer contact with the conductive bar 022, thereby avoiding poor contact between the adapter 01 and the power rail 02.

[0128] An embodiment of the present disclosure provides a track socket, which includes the above-mentioned adapter 01 and / or power track 02.

[0129] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
