[0066] A track socket is a movable socket that includes a power track and an adapter. The power track is the core component of the track socket and provides power to the adapter. The power track is usually provided with a first receiving cavity and a strip-shaped opening. A conductive member is disposed inside the first receiving cavity and is electrically connected to an external power source. The adapter is inserted into the first receiving cavity through the strip-shaped opening and contacts the conductive member to maintain a powered-on state. It can be seen that during the use of the track socket, how to ensure that the adapter always contacts the conductive member is the key to ensuring the power-on stability of the track socket. Moreover, since the power track is always energized during use, how to prevent users from accidentally touching the conductive member through the strip-shaped opening is a key technical problem for ensuring the safety of the track socket.

[0067] Embodiments of the present disclosure provide a power track. Refer to Figure 1, which includes a housing 1, an insulating member 2, a first conductive member 3 and a second conductive member 4. The housing 1 includes a first receiving cavity 101 and a strip-shaped opening 102. The strip-shaped opening 102 is in communication with the first receiving cavity 101. The strip-shaped opening 102 is for inserting the power-taking body of the adapter. The first receiving cavity 101 includes a first side wall 101a and a second side wall 101b. The first side wall 101a and the second side wall 101b are distributed on both sides of the strip-shaped opening 102. The insulating member 2 is located in the first receiving cavity 101 and is arranged opposite to the first side wall 101a. The insulating member 2 has a first rib 21 and a first card slot 22 on the side facing the second side wall 101b. The first rib 21 is located on the side of the first card slot 22 close to the strip-shaped opening 102. Both the first rib 21 and the first card slot 22 extend in the same direction as the strip-shaped opening 102. The first conductive member 3 is located in the first card slot 22 and protrudes from the first card slot 22 towards the second side wall 101b. The first rib 21 protrudes relative to the first conductive member 3. The second conductive member 4 is fixed inside the first receiving cavity 101.

[0068] Wherein, the first conductive member 3 can be an L-pole conductive member. The first conductive member 3 is used to connect the live wire. The second conductive member 4 can be an N-pole conductive member. The second conductive member 4 is used to connect the neutral wire. Refer to Figure 5 , after the adapter 02 is inserted through the above strip-shaped opening 102 into the first receiving cavity 101, the first conductive member 3 is used to contact the first pole piece 0221 of the adapter, and the second conductive member 4 is used to contact the second pole piece 0222 of the adapter.

[0069] It can be understood that the co-directional extension of any of the above-mentioned components means that the extension directions of the components are the same.

[0070] On the one hand, the technical solution provided by the embodiment of the present disclosure sets a first card slot 22 for accommodating the first conductive member 3 on the insulating member 2 and makes at least part of the first conductive member 3 protrude from the first card slot 22. After the adapter is inserted into the first receiving cavity 101, the first pole piece 0221 of the adapter 02 can contact the first conductive member 3 without extending into the first card slot 22. The first pole piece 0221 and the first conductive member 3 are more likely to contact, which can improve the power-on stability of the power rail. On the other hand, on the insulating member 2, by setting a first rib 21 on the side of the first card slot 22 facing the strip-shaped opening 102, the first conductive member 3 is well hidden on the side of the first rib 21 away from the strip-shaped opening 102, and since the side of the first rib 21 facing the second side wall 101b protrudes relative to the first conductive member 3. Even if the user inserts a probe into the first receiving cavity 101, it is not easy to touch the first conductive member 3, and the safety of the power rail is relatively high.

[0071] For a power rail, the anti-electric shock performance of the rail socket is currently usually reflected by the results of probe tests. A probe is a slender metal strip. When conducting a probe test, the tester will use an insulating tool to hold one end of the probe and insert the other end into the first receiving cavity of the rail socket, and then move the probe arbitrarily. If the probe is never electrified during the movement, it proves that the anti-electric shock performance of the power rail is excellent, and it is not easy to get an electric shock when a common metal strip is inserted into the power rail.

[0072] In some possible embodiments, any straight line passing through the strip-shaped opening 102 and tangent to the first rib 21 does not intersect the first conductive member 3.

[0073] In one example, referring to Figure 3 , the first conductive member 3 does not intersect the reference line 001 of the power rail.

[0074] The above reference line 001 is not an actual existing line, but a virtual line that satisfies being tangent to both the first rib 21 and the wall surface of the strip-shaped opening 102 away from the first side wall 101a at the same time. The reference line 001 of the power rail is tangent to the strip-shaped opening 102 and the first rib 21 and does not intersect the first conductive member 3. The intersection point of the reference line 001 and the first receiving cavity 101 is located at the bottom of the first receiving cavity 101, and the first conductive member 3 is located between the first rib 21 and this intersection point. In this way, it can be ensured that after a slender metal strip is inserted into the first receiving cavity 101, the probe will not come into contact with the first conductive member 3, thereby improving the anti-electric shock performance of the power rail.

[0075] In one example, the first rib 21 is an arc-shaped rib. Referring to Figure 2 , the first rib 21 extends in the same direction as the strip-shaped opening 102, and the wall surface of the first rib 21 away from the first side wall 101a is arc-shaped. In this way, during the process of inserting the adapter 02 into the first receiving cavity 101, it is possible to prevent the first pole piece 0221 and the second pole piece 0222 from being deformed due to the obstruction of the first rib 21.

[0076] Optionally, the axis of rotation of the wall surface of the first rib 21 away from the first side wall 101a is located between the insulating member 2 and the first side wall 101a, and this wall surface can be smoothly transitioned with the insulating member 2.

[0077] In this way, there will be no gap between the first rib 21 and the wall surface of the insulating member 2 facing the second side wall 101b.

[0078] Referring to Figure 1, the housing 1 is a cubic cylindrical structure with openings at both ends. A first accommodation cavity 101 is formed inside the cubic cylindrical structure. A strip-shaped opening 102 is provided on the top wall of the cubic cylindrical structure, and the extending direction of the strip-shaped opening 102 is parallel to the edge of the cubic cylindrical structure. The first accommodation cavity 101 includes a first side wall 101a and a second side wall 101b that are parallel to each other, and the first side wall 101a and the second side wall 101b are distributed on both sides of the strip-shaped opening 102.

[0079] The housing 1 can be made of various materials with good mechanical properties, such as stainless steel, aluminum alloy, or engineering plastics, etc. The embodiments of the present disclosure do not limit the material of the housing 1. The housing 1 can be formed by stamping process, or by casting process, or by cutting process. The embodiments of the present disclosure do not limit the processing method of the housing 1.

[0080] Further, referring to Figure 4 , the insulating member 2 is fixed on the first side wall 101a. The insulating member 2 has a first rib 21 and a first card slot 22 on the side facing the second side wall 101b. The first rib 21 is located on the side of the first card slot 22 close to the strip-shaped opening 102 and extends in the same direction as the strip-shaped opening 102. The connection manner between the insulating member 2 and the housing 1 can be snap connection, or bonding, or threaded connection.

[0081] In some possible embodiments, the insulating member 2 is snap-connected to the housing 1.

[0082] As Figure 1 shown, a plurality of retaining ribs 103 and a plurality of screw posts 104 are provided on the inner wall of the housing 1. The screw post 104 includes a transition portion and a connection portion. The transition portion has a strip-shaped structure and extends in the same direction as the strip-shaped opening 102, and one side of the transition portion is connected to the inner wall of the housing 1. The connection portion has a hollow cylindrical structure and is connected to the other side of the transition portion. The axis of the hollow cylindrical structure is parallel to the connection portion. As Figure 6As shown, a strip-shaped opening 102 is located on the top wall of the housing 1. A screw post 104 is provided at the transition position between the first side wall 101a and the bottom wall of the first accommodation cavity 101. A retaining rib 103 is provided on the bottom wall of the first accommodation cavity 101. The retaining rib 103 has a strip-shaped structure and extends in the same direction as the strip-shaped opening 102. There is a gap between the retaining rib 103 on the bottom wall of the first accommodation cavity and the screw post 104 at the above-mentioned transition position, and this gap is used to clamp and fix the end of the insulating part 2. A retaining rib 103 is provided on the first side wall 101a of the first accommodation cavity 101. The cross-section of the retaining rib 103 is L-shaped. The insulating part 2 has a first limiting protrusion 201 on the side facing the first side wall 101a. The cross-section of the first limiting protrusion 201 is also L-shaped and is adapted to the retaining rib 103. The retaining rib 103 is snap-fitted with the first limiting protrusion 201, and the housing 1 limits and fixes the insulating part 2 through the above two retaining ribs 103 inside the first accommodation cavity 101.

[0083] In one example, the above two retaining ribs 103 and multiple screw posts 104 are integrally formed with the housing 1. In this way, the processing cost of the housing 1 can be reduced.

[0084] Optionally, referring to Figure 1 , the insulating part 2 has a support protrusion 202 on the side facing the first side wall 101a. The support protrusion 202 has a plate-shaped structure and is perpendicular to the insulating part 2. The support protrusion 202 extends in the same direction as the strip-shaped opening 102, and the end of the support protrusion 202 away from the insulating part 2 abuts against the first side wall 101a. In this way, the overall strength of the insulating part 2 can be improved.

[0085] The above first limiting protrusion 201 and support protrusion 202 can be integrally formed with the insulating part 2. In this way, the processing cost of the insulating part 2 can be reduced.

[0086] In one example, referring to Figure 6 , the inner ring of the connecting part has an internal thread, and the connecting part is used for detachable connection with the junction box 6 and the end cover 8 in the power rail through thread fitting. In this way, the assembly difficulty of the power rail can be reduced.

[0087] It can be understood that in the power rail, the insulating part 2 is used to limit and fix the first conductive part 3. Therefore, the insulating part 2 is made of a non-conductive material, such as an engineering material. The insulating part 2 can be processed and formed by an injection molding process.

[0088] In some possible embodiments, the second conductive part 4 is fixed to the insulating part 2.

[0089] Referring to Figure 1, on the side of the insulating member 2 facing the second side wall 101b, there is also a second card slot 23. The second card slot 23 extends in the same direction as the strip-shaped opening 102. The second conductive member 4 is snap-fitted with the second card slot 23 and partially protrudes from the second card slot 23.

[0090] In one example, refer to Figure 1 , on the side of the insulating member 2 facing the second side wall 101b, there is also a second rib 24. The second rib 24 is located on the side of the second card slot 23 close to the strip-shaped opening 102 and extends in the same direction as the strip-shaped opening 102. The second rib 24 protrudes relative to the second conductive member 4.

[0091] Wherein, the surfaces of the first conductive member 3 and the second conductive member 4 facing the second side wall 101b of the first accommodation cavity 101 are contact surfaces, and these contact surfaces are used for contact electrical connection with the power-taking body of the adapter. The embodiments of the present disclosure do not limit the shapes and arrangement manners of the first conductive member 3 and the second conductive member 4. In some examples, the first conductive member 3 and the second conductive member 4 are in the shape of long strip-shaped flat plates. In some examples, as Figure 5 shown, both the first conductive member 3 and the second conductive member 4 are strip-shaped structures with a convex-shaped cross-section. The contact surfaces of the first conductive member 3 and the second conductive member 4 are in the same plane and are both parallel to the insertion direction of the adapter.

[0092] During implementation, it is possible that the junction box 6 in the power rail is wired incorrectly, resulting in the polarity reversal of the first conductive member 3 and the second conductive member 4. At this time, the second conductive member 4 is actually energized. The technical solution provided by the embodiments of the present disclosure can make the second conductive member 4 well hidden on the side of the second rib 24 far from the strip-shaped opening 102 by arranging the second rib 24 on the side of the second card slot 23 close to the strip-shaped opening 102. And, since the side of the second rib 24 facing the second side wall 101b protrudes relative to the second conductive member 4. Even if the user inserts a probe into the interior of the first accommodation cavity 101, it is not easy to touch the second conductive member 4, and the safety of the power rail is relatively high.

[0093] For the specific structure of the second rib 24, reference can be made to the introduction of the first rib 21 above, and details will not be repeated here.

[0094] In one example, refer to Figure 1 , the first conductive member 3 is located on the side of the second conductive member 4 far from the strip-shaped opening 102.

[0095] Refer to Figure 1For the insulating member 2, in the direction where the strip-shaped opening 102 points to the bottom wall of the first accommodating cavity 101, the second rib 24, the second card slot 23, the first rib 21, and the first card slot 22 are arranged in sequence. The first conductive member 3 is snap-fitted in the first card slot 22 and protrudes from the first card slot 22 toward the second side wall 101b. The second conductive member 4 is snap-fitted in the second card slot 23 and protrudes from the second card slot 23 toward the second side wall 101b. The side of the second rib 24 facing the second side wall 101b protrudes relative to the second conductive member 4, and the side of the first rib 21 facing the second side wall 101b protrudes relative to the first conductive member 3.

[0096] In the technical solution provided by the embodiment of the present disclosure, by arranging the first card slot 22 on the side of the second card slot 23 away from the strip-shaped opening 102, arranging the first conductive member 3 in the first card slot 22, and arranging the second conductive member 4 in the second card slot 23, in this way, the first conductive member 3 electrically connected to the live wire is farther away from the strip-shaped opening 102. Even if the user uses a probe to extend into the interior of the first accommodating cavity 101, it is not easy to touch the first conductive member 3, and the safety of the power rail is relatively high.

[0097] In one example, refer to Figure 3 , the sides of the first rib 21 and the second rib 24 facing the second side wall 101b are flush. In this way, after the probe or the metal thin plate extends into the first accommodating cavity 101 in the vertical direction, the first rib 21 and the second rib 24 can effectively block the probe or the metal thin plate on the side of the first rib 21 facing the second side wall 101b, avoiding the probe or the metal thin plate from contacting the first conductive member 3, thereby improving the anti-electric shock performance of the power rail.

[0098] It should be noted that in some examples, the power rail provided by the embodiment of the present disclosure only includes the first conductive member 3 and the second conductive member 4, then the adapter can only have a two-pole jack for docking a two-pole plug. In other examples, as Figures 1 - 5 shown, the adapter further includes a third conductive member 5, then the adapter can have a two-pole jack or a three-pole jack, and can be used to dock a two-pole plug and a three-pole plug.

[0099] In some possible embodiments, as Figure 1 shown, the insulating member 2 further has a third card slot 25 on the side facing the second side wall 101b. The third card slot 25 is located on the side of the first rib 21 close to the strip-shaped opening 102. The power rail further includes a third conductive member 5, and the third conductive member 5 is snap-fitted with the third card slot 25 and partially protrudes from the third card slot 25.

[0100] Furthermore, in some examples, refer to Figure 1The insulating member 2 also has a third ridge 26 on the side facing the second side wall 101b. The third ridge 26 is located on the side of the third slot 25 close to the strip opening 102. The third ridge 26 extends in the same direction as the strip opening 102. The third conductive member 5 is located in the third slot 25 and partially protrudes out of the third slot 25 toward the second side wall 101b. The third ridge 26 protrudes relative to the third conductive member 5 on the side facing the second side wall 101b.

[0101] Correspondingly, the third convex strip 26 can improve the anti-electric shock performance of the power rail when the first conductive member and the third conductive member 5 are connected incorrectly. The specific reasons can be referred to the above description and will not be repeated here.

[0102] In an example, the first conductive member 3 is an L-pole conductive member, the second conductive member 4 is an N-pole conductive member, and the third conductive member 5 is an E-pole conductive member.

[0103] For details, see Figure 1 The third conductive member 5, the second conductive member 4 and the first conductive member 3 are arranged in sequence in the insertion direction of the power collector.

[0104] The technical solution provided by the embodiment of the present disclosure is that by setting the third card slot 25 on the side of the first convex strip 21 close to the strip opening 102, and the third conductive member 5 is carded in the third card slot 25, the third conductive member 5 can be closer to the strip opening 102 than the first conductive member 3. During the use of the power rail, the third conductive member 5 is not charged. Therefore, even if a user inserts a finger or a probe into the first accommodating cavity 101, usually only the third conductive member 5 can be touched, and there will be no electric shock. Therefore, the anti-electric shock performance of the power rail can be improved.

[0105] In some possible embodiments, the first conductive member 3 and the first slot 22 are connected by snap-fitting.

[0106] In one example, if Figure 3 As shown, the first conductive member 3 has a first limiting structure 31 on its wall surface facing toward and away from the strip-shaped opening 102 , and the first slot 22 has a second limiting structure 221 on its slot wall opposite to the first limiting structure 31 .

[0107] Among them, one of the first limiting structure 31 and the second limiting structure 221 is a protruding structure, and the other is a groove structure matched with the protruding structure.

[0108] For details, see Figure 3 The first limiting structure 31 may be a protruding structure, and the second limiting structure 221 may be a groove structure, or, see Figure 4 The first limiting structure 31 can be a groove structure, and the second limiting structure 221 can be a protrusion structure.

[0109] It is understandable that the first conductive member 3 may also have the first limiting structure 31 only on one side wall facing or away from the strip-shaped opening 102 , and correspondingly, the first slot 22 may have a second limiting structure on a slot wall opposite to the first limiting structure 31 .

[0110] In the example where the second conductive member 4 and the third conductive member 5 are fixed to the insulating member 2 , the second conductive member 4 and the third conductive member 5 may have the same structure as the first conductive member 3 , and correspondingly, the second card slot 23 and the third card slot 25 may have the same structure, which will not be repeated here.

[0111] For example, see Figure 5 The first conductive member 3 may have a strip-shaped structure. The first conductive member 3 protrudes toward the wall portion of the strip-shaped opening 102 to form a first limiting structure 31 , and the first conductive member 3 protrudes away from the wall portion of the strip-shaped opening 102 to form a first limiting structure 31 .

[0112] In some possible embodiments, the power track further includes a junction box 6 , and the junction box 6 includes a first connector 61 . The first connector 61 is an L-pole connector for connecting to a live wire.

[0113] The first conductive member 3 is fixed in the first slot 22 . A first accommodation space 220 is formed between the first conductive member 3 and the first slot 22 . The first accommodation space 220 is used to accommodate part of the first connecting member 61 .

[0114] Specifically, the first conductive member 3 is a convex structure, and the two side walls of the first slot 22 are respectively provided with a second limiting structure 221, each second limiting structure 221 cooperates with a first limiting structure 31 of the first conductive member 3, and the top of the first conductive member 3 protrudes from the first slot 22. Figure 3 A first accommodating space 220 is defined between the bottom of the first conductive member 3 and the bottom of the first slot 22 . The first accommodating space 220 is used to accommodate a portion of the first connecting member 61 .

[0115] The technical solution provided by the embodiment of the present disclosure forms a first accommodating space 220 between the groove wall of the first slot 22 for fixing the first conductive member 3 and the first conductive member 3 for fixing the first conductive member 3. The first accommodating space 220 is used to accommodate the first connecting member 61 of the junction box 6. Compared with the technical solution of directly fixing the first connecting member 61 and the first conductive member 3 in the related art, in this solution, if the connecting component between the first connecting member 61 and the first conductive member 3 fails, the first accommodating space 220 can still ensure that the first connecting member 61 is located in the first accommodating space 220, thereby realizing the electrical connection between the first connecting member 61 and the first conductive member 3, and improving the connection stability between the connecting member and the conductive member.

[0116] In one example, the junction box 6 further includes a box body 62 and a fixing bracket 63.

[0117] See Figure 8 , the fixing bracket 63 is fixed inside the box body 62. The first connecting member 61 is respectively connected to the fixing bracket 63. The first end of the first connecting member 61 has a first elastic piece 611 and a second elastic piece 612. The first elastic piece 611 extends into the first accommodating space 220, and the first elastic piece 611 abuts against the first conductive member 3. The second elastic piece 612 abuts against the side of the first conductive member 3 close to the second side wall 101b. The second end of the first connecting member 61 is connected to the live wire.

[0118] Specifically, the fixing bracket 63 includes a frame body 631 and a gland 632. The frame body 631 has a second accommodating cavity and a third accommodating cavity connected through a connecting through hole. The second accommodating cavity is located on the side of the third accommodating cavity close to the housing 1. The first connecting member 61 is located in the second accommodating cavity. The gland 632 is located on the side of the frame body 631 close to the housing 1. The gland 632 has a through hole. The first end of the first connecting member 61 passes through the through hole, so that the first elastic piece 611 extends into the first accommodating space 220, and the first elastic piece 611 abuts against the first conductive member 3. The second elastic piece 612 abuts against the side of the first conductive member 3 close to the second side wall 101b.

[0119] Optionally, the junction box 6 may further include a terminal block 64 and a fixing bolt 67. The terminal block 64 is located in the third accommodating cavity. A threaded hole may be formed on the side wall of the frame body 631, and the threaded hole is communicated with the third accommodating cavity. The second end of the first connecting member 61 extends into the third accommodating cavity through the above-mentioned connecting through hole. The fixing bolt 67 is assembled into the threaded hole on the side wall of the frame body 631 and applies a thrust to the terminal block 64. Under the action of this thrust, the second end of the first connecting member 61 and the terminal block 64 clamp and fix the live wire.

[0120] Furthermore, as Figure 6 shown, the junction box 6 further includes a second connecting member 65 and a third connecting member 66. The second connecting member 65 is an N-pole connecting member, and the third connecting member 66 is an E-pole connecting member.

[0121] See Figure 5 , the first conductive member 3, the second conductive member 4, and the third conductive member 5 are all in a convex-shaped structure. Each of the two side walls of the second card slot 23 has a groove structure, and each groove structure cooperates with a convex structure on the side of the second conductive member 4. The top of the second conductive member 4 protrudes from the second card slot 23. Each of the two side walls of the third card slot 25 has a groove structure, and each groove structure cooperates with a convex structure on the side of the third conductive member 5. The top of the third conductive member 5 protrudes from the third card slot 25. See Figure 6, a second accommodating space 230 is formed between the side of the second conductive member 4 facing the first side wall 101a and the second card slot 23. The second accommodating space 230 is used to accommodate a part of the second connecting member 65. A third accommodating space 250 is formed between the side of the third conductive member 5 facing the first side wall 101a and the third card slot 25. The third accommodating space 250 is used to accommodate a part of the third connecting member 66.

[0122] For the specific structures of the second connecting member 65 and the third connecting member 66 and the connection manners with other components in the junction box 6, reference can be made to the above introduction, and details will not be repeated here.

[0123] In the technical solution provided by the embodiments of the present disclosure, by providing groove structures on the two side walls of the first card slot 22, the second card slot 23, and the third card slot 25, the convex structures on the side parts of the corresponding conductive members are fixed, so that the connecting members in the junction box 6 are clamped and fixed by the conductive members and the bottom of the corresponding card slots, which can improve the electrical connection stability between the connecting members and the conductive members.

[0124] Optionally, as Figure 7 shown, the first conductive member 3, the second conductive member 4, and the third conductive member 5 are all strip-shaped structures with a convex cross-section. The tops of the first conductive member 3, the second conductive member 4, and the third conductive member 5 are located on the same plane and are all parallel to the insertion direction of the adapter. In this way, the electrical connection stability between the first conductive member 3, the second conductive member 4, and the third conductive member 5 and the corresponding pole pieces in the adapter can be improved.

[0125] In one example, referring to Figure 6 , the power rail further includes a support member 7, and the support member 7 is fixed to the second side wall 101b. The insulating member 2 has an elastic arm 27 on the side close to the strip-shaped opening 102 and facing the second side wall 101b. The third convex strip 26 is located on the side of the elastic arm facing the second side wall 101b. The third convex strip 26 and the support member 7 are used to clamp and fix the power-taking body of the adapter.

[0126] Specifically, during the process of inserting the power-taking body 022 of the adapter 02 into the first accommodating cavity 101, the power-taking body 022 has a force acting on the third convex strip 26 from the second side wall 101b to the first side wall 101a. This force causes the elastic arm 27 to deform towards the first side wall 101a. Correspondingly, the elastic arm 27 has a force acting on the power-taking body 022 from the first side wall 101a to the second side wall 101b. This force causes the power-taking body 022 to closely adhere to the support member 7. Referring to Figure 7 , that is, the third convex strip 26 and the support member 7 clamp and fix the power-taking body 022 of the adapter. In this way, the stability of the adapter inserted into the first accommodating cavity 101 can be improved.

[0127] Optionally, referring toFigure 6 On one side where the elastic arm 27 faces the strip-shaped opening 102, it can abut against the top wall of the first accommodating cavity 101. In this way, the upper end of the insulating member 2 can be connected to the top wall of the first accommodating cavity 101, which can prevent a gap between the insulating member 2 and the strip-shaped opening 102. During the process of inserting the adapter, it can prevent the end of the power-taking body 022 from being accidentally inserted into the gap between the housing 1 and the insulating member 2.

[0128] Exemplarily, referring to Figure 6 , two retaining ribs 103 are provided on the second side wall 101b of the first accommodating cavity 101. These two retaining ribs 103 are distributed in the direction from the top wall to the bottom wall of the first accommodating cavity 101, and each retaining rib 103 extends in the same direction as the strip-shaped opening 102. On one side of the support member 7 facing the second side wall 101b, there are two second limiting protrusions 71, and the second limiting protrusions 71 are adapted to the retaining ribs 103. The support member 7 and the housing 1 are snap-connected through the cooperation between the second limiting protrusions 71 and the retaining ribs 103.

[0129] In one example, referring to Figure 1 , there is a clearance between the first card slot 22 and the bottom wall of the first accommodating cavity 101. That is, there is a clearance between the first conductive member 3 disposed in the first card slot 22 and the bottom wall of the first accommodating cavity 101.

[0130] The technical solution provided by the embodiments of the present disclosure can prevent water and oil from easily accumulating on the first conductive member 3 and the second conductive member 4 by providing a clearance between the first card slot 22 and the bottom wall of the first accommodating cavity 101, making the power rail particularly suitable for use in a kitchen environment.

[0131] Specifically, as Figure 1 shown, when the rail is horizontally installed (such as when installed on a tabletop), under the action of gravity, water and oil stains will slide down along the wall surface of the first conductive member 3. Since there is a clearance between the first conductive member 3 and the bottom wall of the first accommodating cavity 101, the oil and water will continue to slide down after passing through the first conductive member 3 and flow to the bottom wall of the first accommodating cavity 101 without staying on the first conductive member 3 and the second conductive member 4.

[0132] The embodiments of the present disclosure also provide a track socket, as Figure 7As shown, the track socket includes the above-mentioned power track 01 and the adapter 02. In this track socket, the adapter 02 includes a socket 021 and a power-taking body 022 connected to each other. On the power-taking surface 0220 of the power-taking body 022, there are a first pole piece 0221 and a second pole piece 0222. The protruding height H1 of the first pole piece 0221 relative to the power-taking surface 0220 is greater than the protruding height H2 of the first rib 21 relative to the first conductive member 3. The first pole piece 0221 is an L-pole piece, and the first pole piece 0221 is used to contact the first conductive member 3. The second pole piece 0222 is an N-pole piece, and the second pole piece 0222 is used to contact the second conductive member 4.

[0133] Correspondingly, referring to Figure 7 , when the power track 01 further includes a third conductive member 5, there is also a third pole piece 0223 on the power-taking surface 0220. The third pole piece 0223 is an E-pole piece, and the third pole piece 0223 is used to contact the third conductive member 5.

[0134] The above are only optional embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present disclosure shall be included in the protection scope of the present disclosure.
