[0056] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0057] The embodiments of the present application provide an adapter, as Figure 1 and Figure 2 shown, the adapter 100 includes a connected socket 101 and a power-taking body 102. The socket 101 has a jack 1011; the power-taking body 102 has an E-pole contact part 1021, an N-pole contact part 1022, and an L-pole contact part 1023. In the insertion direction of the power-taking body 102, the width of the E-pole contact part 1021 is greater than the width of the N-pole contact part 1022, and the width of the E-pole contact part 1021 is greater than the width of the L-pole contact part 1023.

[0058] In some embodiments, the adapter 100 can be applied to a side-insert type track socket, and the power-taking body 102 in the adapter 100 is an insertion piece.

[0059] The adapter provided by the embodiment of the present application increases the width of the E - pole contact portion 1021 in the insertion direction of the power - taking body 102. When the adapter 100 is inserted into the power rail, the E - pole contact portion 1021 can contact the electrode conductive member of the corresponding polarity in the power rail prior to the N - pole contact portion 1022 and the L - pole contact portion 1023. Correspondingly, when the adapter 100 is pulled out of the power rail, due to the larger width of the E - pole contact portion 1021, after the N - pole contact portion 1022 and the L - pole contact portion 1023 are separated from the electrode conductive members of the corresponding polarities in the power rail, the E - pole contact portion 1021 will be separated from the E - pole conductive member in the power rail. Thus, the adapter provided by the embodiment of the present application can achieve that the E - pole contact portion 1021 is first electrically connected to the power rail and finally disconnected from the power rail during the insertion and extraction processes of the adapter 100, improving the safety of the insertion and extraction processes of the adapter 100.

[0060] Figure 9 Fig. shows a schematic diagram of the state transition of the cooperation between the adapter and the power rail in the track socket. The left figure shows the normal use state of the adapter 100, at this time the adapter can draw power from the power rail 200; the right figure shows the pulled - out state of the adapter 100, and the adapter is disconnected from the power rail 200.

[0061] See Figure 9 It can be seen that the power rail 200 includes an E - pole conductive member 202, an N - pole conductive member 203, and an L - pole conductive member 204. As shown in the left figure of Figure 9 , when the adapter 100 is inserted in place, the E - pole contact portion 1021 contacts the E - pole conductive member 202, the N - pole contact portion 1022 contacts the N - pole conductive member 203, the L - pole contact portion 1023 contacts the L - pole conductive member 204, and the electrode contact portions on the adapter 100 and the electrode conductive members of the corresponding polarities on the power rail 200 can be basically centered. Thus, when the adapter 100 is pulled out upward by a certain distance, as shown in the right figure of Figure 9 , between the N - pole contact portion 1022 and the N - pole conductive member 203, and between the L - pole contact portion 1023 and the L - pole conductive member 204 have been separated from each other, but the E - pole contact portion 1021 that has moved the same distance has not been separated from the E - pole conductive member 202.

[0062] Similarly, when the E - pole contact portion 1021 in the adapter 100 is inserted near the E - pole conductive member 202 in the power rail 200, for example, see Figure 9In the right figure in [description], the E - pole contact part 1021 first contacts the E - pole conductive part 202, but there is no contact between the N - pole contact part 1022 and the N - pole conductive part 203, and between the L - pole contact part 1023 and the L - pole conductive part 204 yet. Therefore, the adapter provided by the embodiment of the present application can achieve that the E - pole contact part 1021 is first electrically connected to the power rail and finally disconnected from the power rail during the insertion and extraction process of the adapter 100.

[0063] In some embodiments, in the insertion direction of the power - taking body 102, the width of the N - pole contact part 1022 can be the same as the width of the L - pole contact part 1023. In other embodiments, the width of the N - pole contact part 1022 can be different from the width of the L - pole contact part 1023. For example, the width of the N - pole contact part 1022 can be greater than the width of the L - pole contact part 1023, or the width of the N - pole contact part 1022 can be less than the width of the L - pole contact part 1023.

[0064] As Figure 2 and Figure 4 shown, the E - pole contact part 1021, the N - pole contact part 1022, and the L - pole contact part 1023 are located on the same side surface of the power - taking body 102. Exemplarily, the surface of the power - taking body 102 facing the socket 101 can be used as the power - taking surface 1024, and the E - pole contact part 1021, the N - pole contact part 1022, and the L - pole contact part 1023 are respectively located on the power - taking surface 1024. In this way, the E - pole contact part 1021, the N - pole contact part 1022, and the L - pole contact part 1023 protrude in the same direction, which is convenient for processing and helps to reduce the size of the adapter 100 and the power rail 200 that cooperates with it.

[0065] As Figure 3 shown, the N - pole contact part 1022 and the L - pole contact part 1023 are respectively located on the opposite side surfaces of the power - taking body 102, and the E - pole contact part 1021 is located on the same side surface of the power - taking body 102 as any one of the N - pole contact part 1022 and the L - pole contact part 1023. Exemplarily, as Figure 3 shown, the E - pole contact part 1021 and the N - pole contact part 1022 are located on the power - taking surface 1024 of the power - taking body 102 facing the socket 101; the L - pole contact part 1023 is located on the surface of the power - taking body 102 opposite to the power - taking surface 1024. By respectively arranging the N - pole contact part 1022 and the L - pole contact part 1023 on the opposite side surfaces of the power - taking body 102, it helps to avoid generating electric arcs when the adapter 100 is inserted into or pulled out from the power rail 200.

[0066] As Figure 2 and Figure 4As shown, in the insertion direction of the power-taking body 102, the E-pole contact portion 1021 is farther from the insertion end 1025 of the power-taking body 102 than the N-pole contact portion 1022 and the L-pole contact portion 1023. Herein, the insertion end 1025 is the end of the power-taking body 102 that is first inserted into the power rail, and the insertion direction of the power-taking body 102 can be the direction from the end where the power-taking body 102 is connected to the socket 101 towards the insertion end 1025.

[0067] By arranging the E-pole contact portion 1021 in the adapter 100 on the side farthest from the insertion end 1025, in the power rail 200 that cooperates with the adapter 100, as Figure 7 shown, in the insertion direction of the power-taking body 102, the E-pole conductive member 202 is closer to the strip-shaped opening 2012 than the N-pole conductive member 203 and the L-pole conductive member 204. Since the E-pole conductive member 202 is not charged when the power rail 200 is connected to the power supply circuit, by arranging the E-pole conductive member 202 on the side closest to the strip-shaped opening 2012 in the housing 201, even if the user accidentally inserts a conductor into the strip-shaped opening 2012, there will be no electric shock, thus greatly reducing the risk of electric shock to the user.

[0068] When the power-taking body 102 has a power-taking surface 1024 and the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 are respectively located on the power-taking surface 1024, in the direction along the power-taking surface 1024 close to the insertion end 1025 of the power-taking body 102, the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 are arranged in sequence. Thus, in the power rail 200 that cooperates with the adapter 100, the E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204 are arranged in sequence along the direction away from the strip-shaped opening 2012. In this way, by arranging the L-pole conductive member 204 at the position farthest from the strip-shaped opening 2012, the anti-electric shock safety of the power rail 200 is higher.

[0069] Moreover, the N-pole contact portion 1022 and the L-pole contact portion 1023 are respectively located on both sides of the E-pole contact portion 1021. In this way, by arranging the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 in a staggered manner on the power-taking surface 1024, the electrical clearance between adjacent contact portions can be increased under the condition that the size of the power-taking body 102 is certain, thereby improving the use safety.

[0070] In some embodiments, as Figure 4As shown, in the first direction S1 of the power-taking surface 1024, the distance D11 from the N-pole contact portion 1022 to the E-pole contact portion 1021 is equal to the distance D11 from the L-pole contact portion 1023 to the E-pole contact portion 1021. In the second direction S1 of the power-taking surface 1024, the distance D21 from the N-pole contact portion 1022 to the E-pole contact portion 1021 is equal to the distance D22 from the L-pole contact portion 1023 to the E-pole contact portion 1021. Among them, the first direction is perpendicular to the insertion direction of the power-taking body 102, and the second direction is parallel to the insertion direction of the power-taking body 102. In this way, on the basis of ensuring sufficient electrical clearance between adjacent contact portions, the size of the power-taking body 102 can be minimized as much as possible.

[0071] In some embodiments, as Figure 2 and Figure 4 shown, the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 can be elastic pieces. Three exposed holes can be formed on the power-taking body 102, and the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 can be respectively exposed from one exposed hole and bent into an arcuate structure. One end of the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 facing the insertion end 1025 can be suspended relative to the power-taking surface 1024, so that the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 can undergo elastic deformation when subjected to a pressure perpendicular to the power-taking surface 1024.

[0072] As Figure 5 shown, an embodiment of the present application further provides an orbital socket, which includes the adapter 100 and the power rail 200 as described above. As described above, the power rail 200 includes a housing 201, an E-pole conductive member 202, an N-pole conductive member 203, and an L-pole conductive member 204; the housing 201 has a receiving cavity 2011, and the housing 201 is provided with a strip-shaped opening 2012, and the strip-shaped opening 2012 is communicated with the receiving cavity 2011; the E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204 are received in the receiving cavity 2011 and are arranged at intervals along the insertion direction of the power-taking body 102. The power-taking body 102 can be inserted into the strip-shaped opening 2012, and the E-pole contact portion 1021 is in contact with the E-pole conductive member 202, the N-pole contact portion 1022 is in contact with the N-pole conductive member 203, and the L-pole contact portion 1023 is in contact with the L-pole conductive member 204.

[0073] As Figure 7 shown, the housing 201 includes a top wall 2013, a bottom wall 2014, a first side wall 2015, and a second side wall 2016, wherein the top wall 2013 and the bottom wall 2014 are arranged opposite to each other, and the first side wall 2015 and the second side wall 2016 are arranged opposite to each other and are respectively connected between the top wall 2013 and the bottom wall 2014 to enclose the receiving cavity 2011.

[0074] In some embodiments, the track socket may be a side - plug type track socket. The housing 201 in the power track may be generally in the shape of a cuboid, and one side surface thereof (e.g., the first side wall 2015) is fixed on an installation carrier such as a wall or a desktop as the installation surface; one side surface adjacent to the installation surface (e.g., the top wall 2013) may be used as the plug - in surface, and a strip - shaped opening 2012 is formed on the plug - in surface for the power - taking body 102 in the adapter 100 to be inserted; one side surface opposite to the installation surface and adjacent to the plug - in surface (e.g., the second side wall 2016) may be used as the panel surface and face the user. After the power - taking body 102 in the adapter 100 is inserted into the strip - shaped opening 2012, the socket 101 with a jack 1011 in the adapter 100 may be lapped on the panel surface for the user to take power. In one example, the plug - in surface may be the surface defined by the thickness direction and the length direction in the cuboid - shaped housing.

[0075] Optionally, in the insertion direction of the power - taking body 102, the distance from the E - pole conductive member 202 to the N - pole conductive member 203 is greater than the distance between the N - pole conductive member 203 and the L - pole conductive member 204. Since the width of the E - pole contact portion 1021 in the adapter 100 is greater than the width of the N - pole contact portion 1022 and greater than the width of the L - pole contact portion 1023, when the adapter 100 is inserted into the power track 200, the gap between the E - pole contact portion 1021 and the adjacent N - pole conductive member 203 will be smaller than the gap between the N - pole contact portion 1022 and the adjacent L - pole conductive member 204. In this way, by increasing the distance from the E - pole conductive member 202 to the N - pole conductive member 203, it can ensure that there is sufficient electrical clearance around the E - pole conductive member 202 and the E - pole contact portion 1021 adapted to the E - pole conductive member 202.

[0076] In some embodiments, the housing 201 is a conductor and is electrically connected to the E - pole conductive member 202, thereby improving the grounding reliability of the power track 200. In this case, it is necessary to ensure that there is sufficient electrical clearance between the N - pole conductive member 203 and the L - pole conductive member 204 and the housing 201.

[0077] Exemplarily, as Figure 8 shown, the strip - shaped opening 2012 is formed on the top wall 2013, and the E - pole conductive member 202, the N - pole conductive member 203, and the L - pole conductive member 204 are located on the side of the strip - shaped opening 2012 close to the first side wall 2015. The distance L1 from the side edge of the strip - shaped opening 2012 close to the first side wall 2015 to the first side wall 2015 is equal to or greater than the distance L2 from the edge to the second side wall 2016. In this way, the E - pole conductive member 202, the N - pole conductive member 203, and the L - pole conductive member 204 can be basically arranged in the center of the accommodation cavity 2011 to be separated from the first side wall 2015 and the second side wall 2016.

[0078] When the adapter 100 is inserted into the strip-shaped opening 2012, the power-taking surface 1024 faces the first side wall 2015, and the side surface of the power-taking body 102 opposite to the power-taking surface 1024 can abut against the edge of the strip-shaped opening 2012 near the second side wall 2016. The structure of the power-taking body 102 surrounding the E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204 can be made of an insulating material, so that the insulating main body portion in the power-taking body 102 helps to increase the electrical clearance between the electrode conductive members and the electrode contact portions and the second side wall 2016. The distance from the edge of the strip-shaped opening 2012 near the first side wall 2015 to the first side wall 2015 is set to be relatively large, which can ensure the electrical clearance between the electrode conductive members and the electrode contact portions and the first side wall 2015.

[0079] In some embodiments, such as Figure 7 and Figure 8 shown, the power rail 200 further includes a first insulating member 205. The first insulating member 205 is located in the accommodation cavity 2011 and is connected to the housing 201. The first insulating member 205 has three card slots 2051 arranged in sequence and at intervals along the insertion direction of the power-taking body 102. The E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204 are respectively limited in one card slot 2051. In this way, the first insulating member 205 can be used to fix the E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204, and fully isolate the above three electrode conductive members, as well as the N-pole conductive member 203 and the L-pole conductive member 204 from the housing 201. Moreover, the E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204 respectively protrude partially from the corresponding card slots 2051 to facilitate abutting against the E-pole contact portion 1021, the N-pole contact portion 1022, and the L-pole contact portion 1023 in the adapter 100.

[0080] In some embodiments, such as Figure 8As shown, the first insulating member 205 has at least one rib 2052, and the rib 2052 is located between two adjacent card slots 2051. In a projection plane perpendicular to the insertion direction of the power-taking body 102, the orthographic projection of the rib 2052 on the projection plane at least partially overlaps with the orthographic projection of the strip-shaped opening 2012 on the projection plane, so that the rib 2052 can partially extend into the space corresponding to the strip-shaped opening 2012, and the rib 2052 is configured to elastically abut against the power-taking body 102. Thus, when the adapter 100 is inserted into the strip-shaped opening 2012, the rib 2052 elastically abuts against the main body portion in the power-taking body 102, so as to abut the side surface of the power-taking body 102 opposite to the power-taking surface 1024 against one side edge of the strip-shaped opening 2012, to fix the position of the power-taking body 102, prevent the power-taking body 102 from shaking in the strip-shaped opening 2012, and improve the electrical connection stability. The electrode contact portion in the adapter 100 elastically abuts against the electrode conductive member with the corresponding polarity in the power rail 200, further improving the electrical connection stability.

[0081] In some embodiments, as Figure 8 shown, the height by which the E-pole conductive member 202, the N-pole conductive member 203, and the L-pole conductive member 204 protrude from the card slot 2051 is equal to or less than the protruding height of the rib 2052. Since the protruding height of the rib 2052 on the first insulating member 205 is relatively large, when the adapter 100 is inserted into the strip-shaped opening 2012, the position of the power-taking body 102 is mainly fixed by the rib 2052, preventing the electrode contact portion in the adapter 100 and the electrode conductive member 202 in the power rail 200 from being overly pressed and deformed, which may affect the service life.

[0082] In some embodiments, as Figure 7 and Figure 8 shown, the power rail 200 further includes a second insulating member 206. The second insulating member 206 is located in the accommodation cavity 2011 and is connected to the housing 201. The second insulating member 206 is arranged at an interval from the first insulating member 205 and is respectively located on opposite sides of the strip-shaped opening 2012. The second insulating member 206 helps to ensure the electrical clearance between the N-pole conductive member 203 and the L-pole conductive member 204 and the housing 201.

[0083] In some embodiments, the second insulating member 206 may also have a protruding portion on the side facing the strip-shaped opening 2012 for elastically abutting against the power-taking body 102.

[0084] The track socket provided by the embodiment of the present application can increase the width of the E - pole contact part 1021 in the adapter 100 in the insertion direction of the power - taking body 102, and arrange the E - pole conductive part 202 in the power track 200 on the side closest to the strip - shaped opening 2012, so that the E - pole contact part 1021 can be electrically connected to the power track first and disconnected from the power track last during the plug - in and unplugging process of the adapter 100, improving the safety of the plug - in and unplugging process of the adapter 100.
