Description

Technical Field

[0001] This utility model relates to the technical field of sockets with tracks, and more particularly to a socket including a track and an adapter inserted into the track, as well as the corresponding track and adapter. Background Technology

[0002] Existing track sockets (also known as rail sockets) mainly consist of a track and adapters that can be inserted into the track. The adapters can move freely on the track to draw power from different locations, and the number of adapters can be increased or decreased as needed. This makes track sockets highly flexible and widely used.

[0003] However, existing track sockets are thick and bulky. How to meet users' needs for thinner and more compact track sockets is a problem that needs to be solved in this field.

[0004] One existing track socket uses a small five-hole adapter, where the three-hole E-pole insertion port of the adapter is located between the two insertion ports of the two-hole structure. In its track structure, the "L-pole (live) conductive socket" and the "N-pole (neutral) conductive socket" are designed separately, with a groove in the middle, within which the "E-pole (ground) conductive socket" is placed. This track socket has a relatively compact structure, but it still suffers from a relatively large socket thickness. Furthermore, the small five-hole adapter can only accept either two-prong or three-prong plugs at a time, failing to meet the needs of users who require simultaneous use of both two-prong and three-prong plugs. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the above-mentioned problems and / or other problems existing in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, a socket with a track is provided, the socket comprising a track extending in a longitudinal direction and an adapter, the adapter being adapted to be inserted into the track in the thickness direction of the track; wherein the track comprises a first segment and a second segment arranged sequentially in a width direction perpendicular to the longitudinal direction and the thickness direction, wherein an L-pole slot and an N-pole slot are arranged spaced apart in the width direction in the first segment, and an E-pole slot is arranged in the second segment, wherein the L-pole slot, the N-pole slot and the E-pole slot all extend in the longitudinal direction.

[0007] In this design, since the E-pole slot is located in the second section of the track, which is spaced apart from the first section in the width direction of the socket, the E-pole slot is spaced apart from the L-pole slot and the N-pole slot in the width direction. The L-pole slot and the N-pole slot are also spaced apart in the width direction. That is, no two of the L-pole slot, N-pole slot and E-pole slot are stacked in the thickness direction of the socket, thus greatly reducing the thickness of the track socket and meeting the user's demand for a thinner track socket.

[0008] According to one example of the present invention, the adapter includes a first part and a second part corresponding to the first segment and the second segment respectively, and a two-hole structure and a three-hole structure respectively disposed in the first part and the second part, wherein the spacing between the two-hole structure and the three-hole structure is configured to allow the two-prong plug and the three-prong plug to be inserted and used simultaneously.

[0009] Typically, due to the positional relationship between the E-pole slot and the L-pole and N-pole slots in existing rail sockets (e.g., the E-pole slot is located between the L-pole and N-pole slots, or at least two of these three are stacked in the thickness direction of the rail), if it is desired to avoid the problem of two-prong and three-prong plugs not being able to be inserted simultaneously as mentioned in the background art, and to separate the two-hole structure and the three-hole structure in the adapter with sufficient spacing to allow the two-prong and three-prong plugs to be inserted simultaneously, then the position of each slot in the rail, especially the position of the E-pole slot, does not correspond to the position of the conductive piece of the three-hole structure in the adapter in the thickness direction of the entire socket. Therefore, the conductive structures used to electrically connect these conductive pieces (at least the E-pole conductive pieces) in the adapter to the conductive sockets in each slot of the rail require complex structures to achieve this electrical connection.

[0010] In this exemplary solution of the present invention, since the E-pole slot is spaced apart from the L-pole slot and N-pole slot in the width direction of the track, the adapter can include a first part and a second part corresponding to the first and second parts in the thickness direction, wherein a two-hole structure and a three-hole structure are respectively provided, that is, the two-hole structure and the three-hole structure are correspondingly spaced apart in the width direction of the track. This allows both two-pronged and three-pronged plugs to be inserted and used simultaneously without complicating the conductive structure.

[0011] According to one example of the present invention, the height of the space in the second part for accommodating the E-pole of the three-pole plug is greater than the height of the space in the first part for accommodating the L-pole and N-pole of the two-pole plug, and the second engagement surface of the track that engages with the second part is lower than the first engagement surface of the track that engages with the first part.

[0012] In this example, the rail forms a downward recess at the second mating surface with the second part of the adapter, which makes room for the second part of the adapter to extend downwards sufficiently to accommodate the longer E-pole pin. Therefore, the overall thickness of the rail socket is determined only by the height h of the first part of the adapter plus the height of the rail (rather than by the height H of the second part of the adapter accommodating the E-pole pin plus the height of the rail), making the rail socket thinner.

[0013] According to one embodiment of this invention, the L-pole slot and the N-pole slot are separated in the width direction by a single partition wall of the track, and the L-pole socket of the L-pole slot and the N-pole socket of the N-pole slot are arranged in opposite opening directions. This arrangement results in a smaller space occupied by the L-pole slot and the N-pole slot in the track, which is more conducive to the thinning and lightening of the track socket and its manufacturing.

[0014] According to one example of the present invention, the E-pole slot is formed in a second segment adjacent to the first segment, wherein the first segment includes a vertical wall for forming part of the E-pole slot.

[0015] According to one example of the present invention, the adapter includes an L-pole conductive structure, an N-pole conductive structure, and an E-pole conductive structure, wherein the L-pole conductive structure and the N-pole conductive structure extend independently from a first part of the adapter and are adapted to be inserted into the L-pole slot and the N-pole slot, respectively, and the E-pole conductive structure extends from a second part of the adapter and is adapted to be inserted into the E-pole slot.

[0016] According to one example of the present invention, the L-pole socket of the L-pole slot and the N-pole socket of the N-pole slot are arranged with their openings facing each other.

[0017] According to one example of the present invention, the adapter includes an L-pole conductive structure, an N-pole conductive structure, and an E-pole conductive structure. The L-pole conductive structure and the N-pole conductive structure are disposed on the same rotatable shaft. Rotation of the rotatable shaft can simultaneously screw the L-pole conductive structure and the N-pole conductive structure into or out of the L-pole slot and the N-pole slot, respectively.

[0018] According to one embodiment of the present invention, the two-hole structure includes a first L-polar conductive sheet and a first N-polar conductive sheet, and the three-hole structure includes a second L-polar conductive sheet, a second N-polar conductive sheet, and an E-polar conductive sheet. The first L-polar conductive sheet and the second L-polar conductive sheet are both electrically connected to the L-polar conductive structure, the first N-polar conductive sheet and the second N-polar conductive sheet are both electrically connected to the N-polar conductive structure, and the E-polar conductive sheet is electrically connected to the E-polar conductive structure.

[0019] According to one example of the present invention, the E-polar conductive sheet and the E-polar conductive structure are constructed as an integral part.

[0020] According to one embodiment of this invention, the first L-polar conductive sheet and the second L-polar conductive sheet are constructed as a single unit, and / or, the first N-polar conductive sheet and the second N-polar conductive sheet are constructed as a single unit. This single-unit construction reduces the number of components in the socket and simplifies assembly.

[0021] According to an example of the present invention, the tracked socket further includes: an L-pole conductive sleeve disposed in the L-pole slot and adapted to be electrically connected to the L-pole conductive structure; an N-pole conductive sleeve disposed in the N-pole slot and adapted to be electrically connected to the N-pole conductive structure; and an E-pole conductive sleeve disposed in the E-pole slot and adapted to be electrically connected to the E-pole conductive structure, wherein the openings of the L-pole conductive sleeve and the N-pole conductive sleeve are arranged in a direction opposite to each other.

[0022] According to another aspect of the present invention, a track for a rail-type socket is also provided, the track extending in its longitudinal direction and having a thickness direction, wherein the track includes a first segment and a second segment arranged sequentially in a width direction perpendicular to the longitudinal direction and the thickness direction, wherein an L-pole slot and an N-pole slot are arranged spaced apart in the first segment in the width direction, and an E-pole slot is arranged in the second segment, wherein the L-pole slot, the N-pole slot and the E-pole slot all extend in the longitudinal direction.

[0023] According to one example of the present invention, the track is adapted to engage with an adapter, a first segment of the track includes a first engagement surface adapted to engage with the adapter, wherein a second segment of the track includes a second engagement surface adapted to engage with the adapter, the second engagement surface being lower than the first engagement surface.

[0024] According to one example of the present invention, the L-pole socket of the L-pole slot and the N-pole socket of the N-pole slot are arranged in opposite directions.

[0025] According to one example of the present invention, the L-pole slot and the N-pole slot are separated in the width direction by a single partition wall of the track.

[0026] According to one example of the present invention, the L-pole socket of the L-pole slot and the N-pole socket of the N-pole slot are arranged with their openings facing each other.

[0027] According to another aspect of the present invention, an adapter is also provided, comprising a first part and a second part, wherein the height of the first part is less than the height of the second part, and the adapter further comprises a two-hole structure and a three-hole structure respectively disposed in the first part and the second part, wherein the spacing between the two-hole structure and the three-hole structure is configured to allow a two-prong plug and a three-prong plug to be inserted and used simultaneously, wherein the height of the space in the second part for accommodating the E-prong of the three-prong plug is greater than the height of the space in the first part for accommodating the L-prong and N-prong of the two-prong plug.

[0028] According to one example of the present invention, the adapter is adapted to be inserted into a track, wherein the adapter includes an L-pole conductive structure, an N-pole conductive structure and an E-pole conductive structure, wherein the L-pole conductive structure and the N-pole conductive structure extend independently from a first part and are adapted to be inserted into the L-pole slot and the N-pole slot of the track respectively, and the E-pole conductive structure extends from a second part and is adapted to be inserted into the E-pole slot of the track.

[0029] According to one example of the present invention, the adapter is adapted to be inserted into a track, wherein the adapter includes an L-pole conductive structure, an N-pole conductive structure and an E-pole conductive structure, the L-pole conductive structure and the N-pole conductive structure are disposed on the same rotatable shaft, and the rotation of the rotatable shaft can simultaneously screw the L-pole conductive structure and the N-pole conductive structure into or out of the L-pole slot and N-pole slot of the track, respectively.

[0040] Embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, numerous specific details are set forth to enable those skilled in the art to more fully understand and implement the present invention. However, it will be apparent to those skilled in the art that implementations of the present invention may not include some of these specific details. Furthermore, it should be understood that the present invention is not limited to the specific embodiments described.

[0041] In the description of the embodiments of this utility model, terms such as "first," "second," etc., are used to describe the elements of this application. These are used only to distinguish the individual elements and not to limit the order or number of these elements. The terms "comprising" and "having" are used to indicate an open-ended inclusion meaning, and refer to the presence of additional elements / components besides those listed.

[0042] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Figure 1-5A first embodiment is shown, in which the track-mounted socket (also referred to herein as a track socket) includes components along the longitudinal direction (in... Figure 1 The middle is roughly in the left-right direction, in Figure 3 A track 1 (partially shown in the figure) extending in the left-right direction and an adapter 2 are described. The adapter 2 is adapted to be inserted into the track 1 along its thickness direction (specifically achieved by inserting the L-polar conductive structure 23, N-polar conductive structure 24, and E-polar conductive structure 25, the first snap-fit ​​structure 26, and the second snap-fit ​​structure 27, also described below, into the track 1). Figure 2 As shown, the adapter 2 includes a two-hole structure 211 and a three-hole structure 221 disposed therein. A two-prong plug 6, including an L-prong 61 and an N-prong 62, can be inserted into the two-hole structure 211. A three-prong plug 7, including an L-prong 71, an N-prong 72, and an E-prong 73, can be inserted into the three-hole structure 221.

[0043] like Figure 1 , 2 As can be seen, track 1 is provided with an L-pole slot 111, an N-pole slot 112, and an E-pole slot 121, all of which extend along the longitudinal direction of track 1. The L-pole slot 111, N-pole slot 112, and E-pole slot 121 can respectively accommodate an L-pole conductive sleeve 3, an N-pole conductive sleeve 4, and an E-pole conductive sleeve 5 (in... Figure 2 and 4 As can be seen in the diagram, the L-pole conductive socket 3 is electrically connected to the live wire of the power supply system, the N-pole conductive socket 4 is electrically connected to the neutral wire of the power supply system, and the E-pole conductive socket 5 is electrically connected to the protective grounding wire.

[0044] In this description, the direction perpendicular to the aforementioned longitudinal direction and the aforementioned thickness direction is referred to as the width direction of track 1 (in...). Figure 3 (The middle refers to the vertical direction). In an embodiment of this utility model, the track 1 is designed to include a first segment 11 and a second segment 12 arranged sequentially along the width direction, as shown below. Figure 1 , 2As shown, the L-pole slot 111 and N-pole slot 112 are arranged spaced apart along the width direction in the first section 11, and the E-pole slot 121 is arranged in the second section. In this way, since the E-pole slot 121 is located in the second section 12, which is spaced apart from the first section 11 in the width direction of the socket, it is spaced apart from the L-pole slot 111 and N-pole slot 112. The L-pole slot 111 and N-pole slot 112 are also spaced apart in the width direction (the L-pole slot 111 is closer to the E-pole slot 121 than the N-pole slot 112, or the N-pole slot 112 is closer to the E-pole slot 121 than the L-pole slot 111; this invention does not limit this). The L-pole slot 111, N-pole slot 112, and E-pole slot 121 are not stacked in the thickness direction of the socket, thus reducing the thickness of the rail socket and meeting the user's demand for a thinner rail socket.

[0045] Furthermore, in this design, the E-pole slot 121 is no longer positioned between the L-pole slot and the N-pole slot as in the prior art for rail sockets including small five-hole adapters. Instead, the E-pole slot 121 is "pulled apart" from the L-pole slot 111 and the N-pole slot 112, i.e., located on one side of both. This provides convenient conditions for separating the two-hole structure from the three-hole structure. Typically, in the prior art, if it is desired to avoid the problem mentioned in the background art where two-prong and three-prong plugs cannot be inserted simultaneously, and to separate the two-prong and three-prong plugs in the adapter with sufficient spacing to allow simultaneous insertion of two-prong and three-prong plugs, the arrangement of the positional relationship between the E-pole slot, L-pole slot, and N-pole slot in the rail in the existing rail socket (e.g., the E-pole slot is located between the L-pole slot and the N-pole slot, or at least two of the three are stacked in the thickness direction of the rail) makes the position of each slot, especially the position of the E-pole slot, not correspond to the position of the conductive piece of the three-hole structure in the thickness direction of the rail socket. Therefore, in the prior art, the conductive structure of electrically connecting these conductive pieces (at least the E-pole conductive pieces) in the adapter to the conductive sockets of each conductive socket in the rail located in the E-pole slot, L-pole slot, and N-pole slot requires a relatively complex structure to achieve this electrical connection.

[0046] This utility model provides a structure, such as Figure 1 , 2 As shown, the adapter 2 includes a first part 21 and a second part 22 corresponding to the first part 11 and the second part 12, respectively, and a two-hole structure 211 and a three-hole structure 221 respectively disposed in the first part 21 and the second part 22, wherein the spacing between the two-hole structure 211 and the three-hole structure 221 is as follows: Figure 2The configuration shown allows simultaneous insertion of both the two-prong plug 6 and the three-prong plug 7. As described above, since the E-pole slot 121, L-pole slot 111, and N-pole slot 112 in this invention are spaced apart in the width direction of the track 1, the adapter can correspondingly "spread" the spacing between the two-hole structure 211 and the three-hole structure 221, while eliminating the need for complex conductive structures in the adapter to achieve electrical connections between each conductive piece and the corresponding conductive socket in the track.

[0047] like Figure 2-5 As shown, the two-hole structure 211 of adapter 2 includes a first L-polar conductive sheet 212 and a first N-polar conductive sheet 213, and the three-hole structure 221 includes a second L-polar conductive sheet 222, a second N-polar conductive sheet 223, and an E-polar conductive sheet 224. Adapter 2 also includes an L-polar conductive structure 23, an N-polar conductive structure 24, and an E-polar conductive structure 25, as mentioned above, an L-polar conductive sleeve 3 arranged in the L-polar slot 111, an N-polar conductive sleeve 4 arranged in the N-polar slot 112, and an E-polar conductive sleeve 5 arranged in the E-polar slot 121. Specifically, the first L-polar conductive sheet 212 and the second L-polar conductive sheet 222 are both electrically connected to the L-polar conductive structure 23, the first N-polar conductive sheet 213 and the second N-polar conductive sheet 223 are both electrically connected to the N-polar conductive structure 24, and the E-polar conductive sheet 224 is electrically connected to the E-polar conductive structure 25. Furthermore, the L-polar conductive structure 23 and the N-polar conductive structure 24 extend from the first part 21 of the adapter and are respectively inserted into the L-polar conductive sleeves 3 and 4 located in the L-polar slot 111 and the N-polar slot 112. The E-polar conductive structure 25 extends from the second part 22 of the adapter and is adapted to be inserted into the E-polar conductive sleeve 5 located in the E-polar slot 121. Thus, the L-polar conductive structure 23 electrically connects the first L-polar conductive piece 212 and the second L-polar conductive piece 222 to the L-polar conductive sleeve 3 in the track 1, the N-polar conductive structure 24 electrically connects the first N-polar conductive piece 213 and the second N-polar conductive piece 223 to the N-polar conductive sleeve 4 in the track 1, and the E-polar conductive structure 25 electrically connects the E-polar conductive piece 224 to the E-polar conductive sleeve 5 in the track 1.

[0048] On the first part 21 of the adapter 2, there are a first snap-fit ​​structure 26 and a second snap-fit ​​structure 27 that are opposite to each other (in Figure 2 and Figure 4(As can be seen in the image). The first snap-fit ​​structure 26 can be inserted into the guide groove of the track 1 that communicates with the L pole slot 111, and the second snap-fit ​​structure can be inserted into the corresponding guide groove of the track 1 that communicates with the N pole slot 112. The first snap-fit ​​structure 26 can be arranged around the portion of the L pole conductive structure 23 that extends out of the first part. The second snap-fit ​​structure 27 can be arranged around the portion of the N pole conductive mechanism 24 that extends out of the first part. It should be noted that the specific structures of the L pole conductive structure 23 and the N pole conductive structure 24, as well as the driving structures that drive them into or out of the corresponding conductive sockets, are not related to the improvement points of this utility model and are prior art, and will not be described here.

[0049] Preferably, such as Figure 2 As shown, the E-polar conductive sheet 224 and the E-polar conductive structure 25 can be constructed as a single unit. The first L-polar conductive sheet 212 and the second L-polar conductive sheet 222 can also be constructed as a single unit. The first N-polar conductive sheet 213 and the second N-polar conductive sheet 223 can also be constructed as a single unit. This single-unit structure reduces the number of parts, reduces assembly workload, and simplifies the structure of the socket.

[0050] The E terminal of a three-prong plug often uses a longer pin to ensure grounding priority (the ground wire is connected first when inserted and disconnected when removed), achieving better safety protection. For example... Figure 2 As shown, the length of the E-pole 73 of the three-prong plug 7 is greater than the length of the L-pole 61 and N-pole 62 of the two-prong plug 6, and also greater than the lengths of the L-pole 71 and N-pole 72. In the prior art, because the thickness (or height) of the adapter needs to be sufficient to accommodate the length of the longer E-pole, and this is combined with the height of the rail, the overall thickness of the socket is relatively large. However, in this invention, the second engagement surface 115 of the rail 1 that engages with the second part 22 of the adapter is lower than the first engagement surface 214 of the rail that engages with the first part 21 (see...). Figure 1 ), so that the height H of the second part 22 of the adapter ( Figure 4 (As can be seen in the image) It is designed to accommodate the longer E-pin 73. The height of the first part 21 of the adapter is h. The height H of the second part 22 is greater than the height h of the first part 21. In other words, as... Figure 1 , 2 As can be seen from Figure 4, the rail 1 forms a downward recess at the second segment 12, which makes room for the second part 22 of the adapter 1 to extend downwards to accommodate the longer E-pole pin 73. Therefore, the overall thickness of the rail socket is thinner.

[0051] Preferably, such as Figure 1 and 2As shown, the L-pole slot 111 and the N-pole slot 112 are separated by a single partition wall 113 of the track 1 in the width direction, and the L-pole socket 13 of the L-pole slot 111 and the N-pole socket 14 of the N-pole slot 112 are arranged with opposite opening directions. In other words, the L-pole slot 111 and the N-pole slot 112 are arranged back to back, separated only by a single partition wall 113. This arrangement makes the structure of the L-pole slot 111 and the N-pole slot 112 in the track 1 simple, occupies little space, and is more conducive to the thinning and lightening of the track socket and its manufacturing.

[0052] like Figure 1 As shown, the E-pole slot 121 may be formed in the second segment 12 adjacent to the first segment 11, wherein the first segment 11 includes a vertical wall 114 for forming a part of the E-pole slot 121. Figure 4 As shown, the E-polar conductive structure 25 is inserted into the E-polar conductive sleeve 5 located in the E-polar slot 121, and the other end of the E-polar conductive structure 25 can be electrically connected to the E-polar pin 73 of the three-prong plug 7 via the E-polar conductive piece 224.

[0053] The following reference Figure 6 and 7 This describes a track-equipped socket and track 1' according to a second embodiment of the present invention. Components identical to those in the first embodiment are represented by the same numbers but distinguished by the superscript '. Unlike the first embodiment, as shown... Figure 6 As shown, in the track 1' of this second embodiment, the L-pole socket 13' of the L-pole slot 111' and the N-pole socket 14' of the N-pole slot 112' are arranged with their openings facing each other. Therefore, the L-pole slot 111' and the N-pole slot 112' are as follows: Figure 6 As shown, they share a longitudinal groove 110' located in the first section 11' of the track, which can reduce the width of the track and thus reduce the volume occupied by the entire socket.

[0054] Accordingly, such as Figure 7 As shown, the L-pole conductive structure 23' and N-pole conductive structure 24' of the adapter 2' are disposed on the same rotatable shaft 20'. The rotatable shaft 20' can be accessed via a button 28'. Figure 6 Driven by the rotatable shaft 20', it rotates in one direction, thereby causing the L-polar conductive structure 23' and N-polar conductive structure 24' mounted on the rotatable shaft 20' to rotate together, so that the L-polar conductive structure 23' and N-polar conductive structure 24' can be simultaneously screwed into the L-polar slot 111' and N-polar slot 112' respectively (as shown in the image). Figure 7(As shown in the diagram). After being screwed into place, the conductive plates of the L-pole conductive structure 23' and the N-pole conductive structure 24' can be positioned, for example, at an acute angle relative to the longitudinal direction of the L-pole slot 111' and the N-pole slot 112', in the L-pole slot 111' and the N-pole slot 112', respectively, and electrically connected to the L-pole conductive sleeve 3' and the N-pole conductive sleeve 4'. The L-pole conductive structure 23' and the N-pole conductive structure 24' are disposed on the same rotatable shaft 20', but they are electrically insulated from each other.

[0055] When the rotatable shaft 20' is rotated in another direction by another button 28', it can drive the L-pole conductive structure 23' and N-pole conductive structure 24' on it to rotate out from the L-pole slot 111' and N-pole slot 112' at the same time.

[0056] Since the L-polar conductive structure 23' and the N-polar conductive structure 24' are mounted on the same rotatable shaft 20', and only one rotatable shaft 20' is used to extend into the longitudinal groove 110' of the track 1', the width of the longitudinal groove 110' is smaller compared to the scheme where the rotating shafts of the L-polar conductive structure and the N-polar conductive structure are inserted into the track separately. This helps to reduce the width of the track and thus the overall volume occupied by the socket. Furthermore, the driving method of sharing a single rotatable shaft for the L-polar conductive structure 23' and the N-polar conductive structure 24' simplifies the structure of the adapter 2'.

[0057] In the first and second embodiments described above, tracks 1, 1' and adapters 2, 2' are described in combination. However, this invention also claims protection for individual tracks adapted for plugging in adapters. Those skilled in the art will understand that such tracks have the various structures described above, and that the arrangement of these structures provides various advantages described herein, such as reducing the thickness of the tracks and facilitating a reduction in the overall thickness of the socket.

[0058] This utility model also claims protection for a separate adapter adapted for insertion into a track. The adapter 2 includes, as follows: Figure 1 , 4 The first part 21 and the second part 22, wherein the height h of the first part 21 is less than the height H of the second part 22. For example... Figure 2As shown, the adapter 2 also includes a two-hole structure 211 and a three-hole structure 221 respectively disposed in the first part 21 and the second part 22, wherein the spacing between the two-hole structure 211 and the three-hole structure 221 is configured to allow the two-prong plug 6 and the three-prong plug 7 to be inserted simultaneously. The length of the E-prong 73 of the three-prong plug 7 is greater than the length of the L-prong 61 and N-prong 62 of the two-prong plug 6, and the height H of the second part 22 of the adapter is adapted to accommodate the E-prong 73. In other words, the height of the space in the second part used to accommodate the E-prong 73 of the three-prong plug 7 is greater than the height of the space in the first part used to accommodate the L-prong 61 and N-prong 62 of the two-prong plug 6. This adapter can accommodate a longer E-prong without increasing the thickness of the overall socket.

[0059] like Figure 2 As shown, the adapter 2 includes an L-pole conductive structure 23, an N-pole conductive structure 24, and an E-pole conductive structure 25, wherein the L-pole conductive structure 23 and the N-pole conductive structure 24 extend independently from the first part 21 and are adapted to be inserted into the L-pole slot 111 and the N-pole slot 112 of the track, respectively, and the E-pole conductive structure 25 extends from the second part 21 and is adapted to be inserted into the E-pole slot 121 of the track.

[0060] like Figure 7 As shown, adapter 2 includes an L-polar conductive structure 23', an N-polar conductive structure 24', and an E-polar conductive structure. In this embodiment, the L-polar conductive structure 23' and the N-polar conductive structure 24' are disposed on the same rotatable shaft 20'. Rotation of the rotatable shaft 20' allows the L-polar conductive structure 23' and the N-polar conductive structure 24' to be simultaneously screwed into or out of the L-polar slot 111' and N-polar slot 112' of the track, respectively.

[0061] For those skilled in the art, various modifications and variations can be made to the embodiments disclosed above without departing from the scope or concept of this utility model. These modified and varied technical solutions are also within the scope of this utility model. This specification and the examples disclosed herein should be considered exemplary only, and the true scope of this utility model is defined by the appended claims and their equivalents.
