[0071] To make the technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.
[0072] The track socket is a mobile socket, including: an electrical connector and a live rail. Among them, the live rail is used for power supply, and the electrical connector is used for power extraction. The electrical connector slides along the live rail and can extract power at any power extraction position on the live rail. When an external electrical component is electrically connected to the electrical connector, for example, by plugging, the live rail, the electrical connector, and the external electrical component form a conductive path to achieve power supply from the live rail to the external electrical component. Since the electrical connector in the track socket is movable, the power extraction method of the external electrical component connected to the electrical connector is more flexible.
[0073] In the related art, the inside of the live rail has a receiving cavity extending along the length direction. On the opposite side walls of the receiving cavity along the length direction, there are respectively an L-pole conductor and an N-pole conductor with a socket structure, and an E-pole conductor is provided on the bottom wall of the receiving cavity along the length direction. The bottom of the electrical connector has elastic contact pins corresponding to the above conductors. After the bottom of the electrical connector is assembled into the receiving cavity of the rail, the two elastic contact pins corresponding to the L-pole conductor and the N-pole conductor are respectively inserted into the L-pole conductor and the N-pole conductor for power extraction.
[0074] Since both the L-pole conductor and the N-pole conductor adopt a socket structure with a relatively large volume, and the L-pole conductor and the N-pole conductor in the socket shape are both located on the side walls of the receiving cavity, the thickness of the live rail must be thick enough to accommodate the above conductors. At the same time, both the top and bottom of the L-pole conductor and the N-pole conductor are used for electrical contact, so that a relatively large frictional force will be generated when the elastic contact pins are inserted, resulting in more wear.
[0075] An embodiment of the present disclosure provides a live rail, as shown in the attached Figure 1 or the attached Figure 2 As shown, the live rail includes: a rail body 1, a first conductive sheet 21, a second conductive sheet 22, and a third conductive sheet 23.
[0076] The inside of the rail body 1 has a receiving cavity 11 extending along the length direction of the rail body 1. The top of the rail body 1 has an opening 12 extending along the length direction of the rail body 1, and the opening 12 is communicated with the receiving cavity 11.
[0077] The first conductive sheet 21 and the second conductive sheet 22 are respectively located on the inner side of the top wall of the receiving cavity 11 on both sides of the opening 12, and both the first conductive sheet 21 and the second conductive sheet 22 extend along the length direction of the rail body 1; the bottoms of the first conductive sheet 21 and the second conductive sheet 22 are used for electrical contact; the third conductive sheet 23 is located on the inner side of the bottom wall of the receiving cavity 11 and extends along the length direction of the rail body 1, and the top of the third conductive sheet 23 is used for electrical contact.
[0078] Among them, one of the first conductive sheet 21 and the second conductive sheet 22 is an L-pole conductive sheet, the other is an N-pole conductive sheet, and the third conductive sheet 23 is an E-pole conductive sheet.
[0079] In the energized guide rail provided by the embodiment of the present disclosure, a first conductive sheet 21, a second conductive sheet 22, and a third conductive sheet 23 are respectively arranged along the length direction in the accommodation cavity 11 of the guide rail body 1. Each of the above conductive sheets has a sheet-like structure, with a smaller volume, so that the volume of the accommodation cavity 11 is also correspondingly reduced, and thus the thickness of the energized guide rail 1 can be effectively reduced. Since the first conductive sheet 21 and the second conductive sheet 22 are both located on the top wall of the accommodation cavity 11 and only the bottoms of them are used for electrical contact, in this way, the electrical contact area between the first conductive sheet 21 and the second conductive sheet 22 and the electrical connector is reduced, and thus the friction area is reduced, which is beneficial to reducing wear.
[0080] The structural arrangements of the components in the energized guide rail 1 provided by the embodiment of the present disclosure are described separately as follows:
[0081] For the guide rail body 1
[0082] In some possible implementation manners, as shown in the appendix Figure 1 the guide rail body 1 includes: a top plate 101, a bottom plate 102, and two first side plates 103. One of the first side plates 103 is connected to the upper and lower ends of the upper and lower ends of one side of the top plate 101 and the bottom plate 102 extending along the length direction, and the other first side plate 103 is connected to the upper and lower ends of the upper and lower ends of the other side of the top plate 101 and the bottom plate 102 extending along the length direction. The two first side plates 103, the top plate 101, and the bottom plate 102 with the above connection relationship cooperate to form the accommodation cavity 11.
[0083] On the top plate 101, for example, an opening 12 is formed in the middle of the top plate 101 along the length direction of the top plate 101. The opening 12 is communicated with the accommodation cavity 11 and is used for the power-taking part of the electrical connector to be inserted, so that the power-taking part of the electrical connector can smoothly enter the accommodation cavity 11 to take power.
[0084] In some possible implementation manners, as shown in the appendix Figure 1 two second side plates 104 are symmetrically arranged along the length direction inside the accommodation cavity 11. The two second side plates 104 are respectively located on both sides of the opening 12. The upper and lower ends of the second side plates 104 are respectively connected to the top plate 101 and the bottom plate 102 at the corresponding positions, for example, perpendicularly connected.
[0085] The accommodation cavity 11 is divided into three parts by the two second side plates 104, which are: an intermediate cavity, and side cavities located on both sides of the intermediate cavity. Among them, the first conductive sheet 21, the second conductive sheet 22, and the third conductive sheet 23 are arranged in the intermediate cavity. In this way, the power-taking part of the electrical connector can be inserted into the intermediate cavity through the opening 12 to make electrical contact with the above conductive sheets.
[0086] A reinforcing structure is provided inside the side cavity. For example, the reinforcing structure can be a reinforcing plate (not labeled in the figure) parallel to the top plate 101 and the bottom plate 102. Both ends of the reinforcing plate are respectively connected to the first side plate 103 and the second side plate 104, so as to significantly improve the structural stability of the guide rail body 1.
[0087] In some possible implementation manners, the guide rail body 1 further includes: two cover plates (not labeled in the figure), wherein the two cover plates are respectively located at both ends of the top plate 101 and the bottom plate 102 perpendicular to the length direction, and each cover plate is simultaneously connected to the ends of the top plate 101, the bottom plate 102 and the two side plates 103. The cover plates are used to block the two ports of the accommodating cavity 11 to protect the components inside the accommodating cavity 11.
[0088] The connection manner between the cover plate and the ends of the top plate 101, the bottom plate 102 and the two side plates 103 is a detachable connection. For example, screw through holes are provided on the cover plate, and screw mounting sleeves (not labeled in the figure) are provided at positions corresponding to the screw through holes on the reinforcing plate. The screws pass through the screw through holes on the cover plate and are threadedly connected to the screw mounting sleeves, so as to achieve the above detachable connection.
[0089] For the first conductive sheet 21 and the second conductive sheet 22
[0090] One of the first conductive sheet 21 and the second conductive sheet 22 is an L - pole (live wire) conductive sheet, and the other is an N - pole (neutral wire) conductive sheet. The two are symmetrically arranged on the inner side of the top wall of the accommodating cavity 11 on both sides of the opening 12. In some possible implementation manners, the structures of the first conductive sheet 21 and the second conductive sheet 22 are the same, so as to simplify the structure of the energized guide rail.
[0091] Regarding the structural arrangement of the first conductive sheet 21 and the second conductive sheet 22 in the length direction, as an example, as shown in the appendix Figure 3 The first conductive sheet 21 and the second conductive sheet 22 both include: a plurality of conductive segments 203 distributed along the length direction and a plurality of gaps 204, wherein each gap 204 is located between two adjacent conductive segments 203.
[0092] Taking the first conductive sheet 21 as an example, referring to the appendix Figure 3 A plurality of conductive segments 203 are sequentially and spacedly distributed along the length direction of the first conductive sheet 21, and the bottom of each conductive segment 203 is used for electrical contact. Each gap 204 extends along the width direction of the first conductive sheet 21 and does not penetrate the two ends of the first conductive sheet 21 along the width direction. In this way, the first conductive sheet 21 still remains as an integral structure.
[0093] Due to the existence of the gap 204, multiple conductive segments 203 can avoid being affected by each other. For example, when the power-taking parts of multiple electrical connectors are simultaneously inserted into the accommodation cavity 11 of the energized guide rail 1, the power-taking parts of the multiple electrical connectors are respectively in electrical contact with the conductive segments 203 at corresponding positions. In this way, the power-taking part of a certain electrical connector only supports the conductive segment 203 in contact with it upward, only causing the conductive segment 203 to have an upward movement tendency, rather than causing other adjacent conductive segments 203 to also obtain an upward movement tendency. That is, these other conductive segments 203 remain in their original positions. In this way, the power-taking parts of multiple electrical connectors can achieve more reliable electrical contact with the conductive segments 203 at corresponding positions.
[0094] In addition, the existence of the gap 204 is also beneficial to reducing the weight of the first conductive sheet 21 and the second conductive sheet 22, which is conducive to saving raw material costs.
[0095] In the embodiments of the present disclosure, the widths of the multiple gaps 204 are the same. Exemplarily, the width of the gap 204 is 1 mm - 4 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, etc. The gaps 204 with the above widths can not only achieve effective mechanical isolation between the conductive segments 203, but also facilitate the erosion forming on the above conductive sheets.
[0096] Regarding the structural arrangement of the first conductive sheet 21 and the second conductive sheet 22 in the width direction, as an example, as shown in the attached Figure 4 As shown, the first conductive sheet 21 and the second conductive sheet 22 both include: a connecting portion 201 and an electrical contact portion 202; the connecting portion 201 is insulated and connected to the wall at the corresponding position of the accommodation cavity 11.
[0097] The electrical contact portion 202 is a hollow convex structure, and the convex direction of the electrical contact portion 202 faces the bottom wall of the accommodation cavity 11. With such a setting, when the electrical contact portion 202 contacts the power-taking part of the electrical connector, due to its hollow convex structure, it has a certain elasticity, which is conducive to reducing wear.
[0098] In a possible implementation manner, the electrical contact portion 202 is an arc-shaped convex structure.
[0099] In a possible implementation manner, as shown in the attached Figure 4 As shown, the electrical contact portion 202 includes: a first support segment 2021, a contact segment 2022, and a second support segment 2023, and both the first support segment 2021 and the second support segment 2023 are inclined.
[0100] The first end of the first support segment 2021 is connected to the connecting portion 201, and the second end of the first support segment 2021 extends towards the bottom wall of the accommodating cavity 11 and is connected to the first end of the contact segment 2022; the second end of the contact segment 2022 is connected to the first end of the second support segment 2023, and the second end of the second support segment 2023 extends towards the top wall of the accommodating cavity 11. Wherein, the contact segment 2022 can be horizontal or arc-shaped.
[0101] The second end of the first support segment 2021 extends towards the bottom wall of the accommodating cavity 11 and is connected to the first end of the contact segment 2022, and, the first end of the second support segment 2023 also extends towards the bottom wall of the accommodating cavity 11 and is connected to the first end of the contact segment 2022, so that the electrical contact portion 202 of the first conductive sheet 21 and the second conductive sheet 22 forms a hollow convex structure with the convex direction facing the bottom wall of the accommodating cavity 11.
[0102] The bottom of the contact segment 2022 is used for electrical contact. Supported by the first support segment 2021 and the second support segment 2023, a gap is formed between the contact segment 2022 and the top wall of the accommodating cavity 11, making the electrical contact portion 202 elastic. Both the first conductive sheet 21 and the second conductive sheet 22 are metal sheets, which is beneficial to increasing the elasticity of the electrical contact portion 202.
[0103] The gap height between the contact segment 2022 and the top wall of the accommodating cavity 11 is directly related to the inclination and length of the first support segment 2021 and the second support segment 2023. By designing the inclination and length of the first support segment 2021 and the second support segment 2023 differently, different above-mentioned gap heights can be adaptively obtained.
[0104] Exemplarily, the gap height between the contact segment 2022 and the top wall of the accommodating cavity 11 is 1.5 mm - 5 mm. For example, it is 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, etc.
[0105] Taking the first conductive sheet 21 as an example, after the power-taking part of the electrical connector makes multiple electrical contacts with the bottom of the first conductive sheet 21, it will cause certain wear to the bottom of the first conductive sheet 21, causing the contact position at the bottom of the contact segment 2022 to move upward. In this case, in order to make the power-taking part of the electrical connector always keep in contact with the bottom of the first conductive sheet 21, when installing the first conductive sheet 21, the contact position at the bottom of the contact segment 2022 is moved downward by a certain distance from the normal contact position to compensate for the problem of the upward movement of the contact position at the bottom of the contact segment 2022 caused by this wear (wherein, the downward movement distance of the contact position at the bottom of the contact segment 2022 is generally determined according to the wear thickness of the worn part at its bottom).
[0106] It can be seen that based on the above structural design, when the power-taking part of the electrical connector is in electrical contact with the bottom of the contact section 2022, since the electrical contact part 202 is elastic, when the power-taking part of the electrical connector contacts the bottom of the contact section 2022, it squeezes the contact section 2022 upward to cause elastic deformation. In this way, even if the contact position at the bottom of the contact section 2022 moves downward relative to the normal contact position, it can still achieve smooth electrical contact with the power-taking part of the electrical connector. After multiple electrical contacts, even if the bottom of the contact section 2022 is worn, its bottom contact position can still be maintained within the normal contact position range to achieve normal electrical contact with the power-taking part of the electrical connector.
[0107] Furthermore, in the energized guide rail provided by the embodiment of the present disclosure, there is a gap between the second end of the second support section 2023 and the top wall of the accommodation cavity 11. For example, the height of the gap between the second end of the second support section 2023 and the top wall of the accommodation cavity 11 is 1 mm - 2.5 mm. By providing the above gap between the second end of the second support section 2023 and the top wall of the accommodation cavity 11, it is beneficial to increase the elasticity of the electrical contact part 202.
[0108] Furthermore, in the energized guide rail provided by the embodiment of the present disclosure, as shown in the appended Figure 4 figure, the electrical contact part 202 further includes: a horizontal section 2024, wherein the first end of the horizontal section 2024 is connected to the second end of the second support section 2023, and the second end of the horizontal section 2024 extends in a direction away from the contact section 2022. The horizontal section 2024 is parallel to the top wall of the accommodation cavity 11, and there is a gap between the horizontal section 2024 and the top wall of the accommodation cavity 11.
[0109] For example, the height of the gap between the horizontal section 2024 and the top wall of the accommodation cavity 11 is 1 mm - 2.5 mm.
[0110] When the power-taking part of the electrical connector is in electrical contact with the bottom of the contact section 2022 and squeezes the contact section 2022 upward, the horizontal section 2024 can contact the top wall of the accommodation cavity 11. By using the top wall of the accommodation cavity 11 to provide stable support for the horizontal section 2024, it can prevent the elastic electrical contact part 202 from deforming, which is beneficial to improving the structural stability of the electrical contact part 202.
[0111] For the third conductive sheet 23
[0112] The third conductive sheet 23 is an E-pole conductive sheet, and the third conductive sheet 23 is connected to the bottom wall of the accommodation cavity 11. For example, it can also be opposite to the opening 12.
[0113] The above-mentioned gap 204 may not be provided along the length direction on the third conductive sheet 23, or the above-mentioned gap 204 may be provided to achieve the purpose of weight reduction.
[0114] In the width direction of the third conductive sheet 23, as shown in the attached Figure 5 figure, the third conductive sheet 23 includes: two connecting portions 201 and an electrical contact portion 202. Among them, the two connecting portions 201 are respectively connected to both ends of the electrical contact portion 202 in the width direction.
[0115] As an example, as shown in the attached Figure 5 figure, the electrical contact portion 202 of the third conductive sheet 23 includes: a third inclined section 2025, an electrical contact section 2026, and a fourth inclined section 2027. Among them, the first end of the third inclined section 2025 is connected to one connecting portion 201, the second end of the third inclined section 2025 extends in a direction away from the bottom wall of the accommodating cavity 11, and the second end of the third inclined section 2025 is connected to the first end of the electrical contact section 2026. The second end of the electrical contact section 2026 is connected to the first end of the fourth inclined section 2027. The second end of the fourth inclined section 2027 extends in a direction close to the bottom wall of the accommodating cavity 11, and the second end of the fourth inclined section 2027 is connected to the other connecting portion 201. Among them, the electrical contact section 2026 can be horizontal (see the attached Figure 5 figure), or it can be arc-shaped.
[0116] With such a setting, the electrical contact portion 202 of the third conductive sheet 23 forms a hollow boss structure with the convex direction facing the top wall of the accommodating cavity 11 (for example, facing the opening 12), so that the electrical contact portion 202 of the third conductive sheet 23 has elasticity. The third conductive sheet 23 is a metal sheet, which is beneficial to increasing the elasticity of its electrical contact portion 202.
[0117] During application, the top of the electrical contact section 2026 is in electrical contact with the bottom of the power-taking portion of the electrical connector. And, based on the above structure of the third conductive sheet 23, it can be ensured that in case of wear, the top of the electrical contact section 2026 and the bottom of the power-taking portion of the electrical connector will still maintain good contact.
[0118] The connecting portions 201 of the above conductive sheets are insulated and connected to the walls at the corresponding positions of the accommodating cavity 11. When the material of the guide rail body 1 is an insulating material, such as a polymer resin material, a ceramic material, etc., at this time, the connecting portion 201 can be directly connected to the wall at the corresponding position of the accommodating cavity 11.
[0119] When the material of the guide rail body 1 is a conductive material, such as a metal material such as aluminum alloy, etc., at this time, the energized guide rail provided by the embodiment of the present disclosure further includes: an insulating partition 3. The connecting portions 201 of the above conductive sheets are connected to the walls at the corresponding positions of the accommodating cavity 11 through the insulating partition 3 to achieve the purpose of insulating connection.
[0120] In some possible implementation manners, as shown in the attached Figure 6 figure, the insulating partition 3 includes: a first cavity portion 31 having a first cavity and a second cavity portion 32 having a second cavity.
[0121] The first cavity of the first cavity portion 31 substantially belongs to the opening 12 and is used for the power-taking portion of the electrical connector to be inserted therethrough. Moreover, the first cavity portion 31 is clamped to the walls on both sides of the opening 12 of the guide rail body 1 and is accommodated inside the opening 12. By way of example, a clamping groove is provided along the length direction on the top wall of the guide rail body 1, and a clamping block corresponding to the clamping groove is provided along the length direction on the top of the first cavity portion 31. The clamping block is clamped in the clamping groove to realize the clamping connection between the first cavity portion 31 and the guide rail body 1.
[0122] The second cavity portion 32 is connected to the first cavity portion 31 and is accommodated in the accommodation cavity 11, specifically inside the middle cavity of the accommodation cavity 11. The second cavity of the second cavity portion 32 substantially belongs to the accommodation cavity 11 and is used for accommodating the first conductive sheet 21, the second conductive sheet 22, and the third conductive sheet 23. At this time, the connection between the connection portion 201 and the insulating partition 3 is substantially the connection between the connection portion 201 and the inner wall of the second cavity portion 32.
[0123] In one case, the connection portion 201 is directly connected to the wall of the accommodation cavity 11, or, in another case, the connection portion 201 is directly connected to the insulating partition 3. The specific connection methods corresponding to these two cases may be the same.
[0124] The following takes the case where the energized guide rail includes the insulating partition 3 as an example to illustrate the connection method between the connection portion 201 of each conductive sheet and the insulating partition 3:
[0125] For the connection between the connection part 201 of the first conductive sheet 21 and the second conductive sheet 22 and the insulating partition 3:
[0126] In some possible implementation manners, as shown in the appendix Figure 4 The connection portions 201 of the first conductive sheet 21 and the second conductive sheet 22 are bent; the inner wall of the insulating partition 3 has a side clamping block 301, and a bent clamping groove is formed between the side clamping block 301 and the inner wall of the insulating partition 3; the connection portion 201 is clamped in the bent clamping groove to realize fixation.
[0127] Further, by way of example, as shown in the appendix Figure 4 The bent connection portions 201 of the first conductive sheet 21 and the second conductive sheet 22 include: a first horizontal connection segment 2011, a vertical connection segment 2012, and a second horizontal connection segment 2013 that are sequentially connected, wherein the first horizontal connection segment 2011 and the second horizontal connection segment 2013 are located on the same side of the vertical connection segment 2012.
[0128] The first horizontal connection segment 2011 is connected to the lower end of the vertical connection segment 2012, the second horizontal connection segment 2013 is connected to the upper end of the vertical connection segment 2012, and the top wall of the second horizontal connection segment 2013 abuts against the inner side of the top wall of the insulating partition 3.
[0129] As an example, as shown in the appendix Figure 4 As shown, the side clamping block 301 includes: a first horizontal clamping section 3011, a first vertical clamping section 3012, and a second horizontal clamping section 3013. Among them, the first end of the first horizontal clamping section 3011 is connected to the inner side wall of the insulating partition 3, the second end of the first horizontal clamping section 3011 is connected to the first end of the first vertical clamping section 3012, the second end of the first vertical clamping section 3012 extends in a direction close to the top wall of the insulating partition 3, and there is a first gap between the second end of the first vertical clamping section 3012 and the top wall of the insulating partition 3; the second horizontal clamping section 3013 is located above the first horizontal clamping section 3011, and there is a second gap between them; the first end of the second horizontal clamping section 3013 is connected to the first vertical clamping section 3012, the second end of the second horizontal clamping section 3013 extends in a direction close to the side wall of the insulating partition 3, and there is a third gap between the second end of the second horizontal clamping section 3013 and the inner side wall of the insulating partition 3.
[0130] The above-mentioned first gap, second gap, and third gap cooperate to form the above-mentioned bent clamping groove.
[0131] During application, the first horizontal connecting section 2011 is clamped in the second gap between the first horizontal clamping section 3011 and the second horizontal clamping section 3013, the vertical connecting section 2012 is clamped in the third gap between the second horizontal clamping section 3013 and the inner side wall of the insulating partition 3, and the second horizontal connecting section 2013 is clamped in the first gap between the first vertical clamping section 3012 and the inner top wall of the insulating partition 3. In this way, the first horizontal connecting section 2011, the vertical connecting section 2012, and the second horizontal connecting section 2013 are simultaneously clamped with the side clamping block 301.
[0132] When installing the first conductive sheet 21 and the second conductive sheet 22, enter from one of the ports of the accommodating cavity 11, and insert the connecting part 201 of the first conductive sheet 21 and the second conductive sheet 22 into the clamping cavity formed by the side clamping block 301. After the installation of the first conductive sheet 21 and the second conductive sheet 22 is completed, use the cover plate to block the two ports of the accommodating cavity 11 to protect the components inside the accommodating cavity 11.
[0133] For the connection between the connection part 201 of the third conductive sheet 23 and the insulating partition 3:
[0134] In some possible implementation manners, as shown in the appendix Figure 5 As shown, the connecting parts 201 of the third conductive sheet 23 are located at opposite ends of the electrical contact part 202 and are sheet-like structures extending in the horizontal direction; there is a bottom clamping block 302 on the inner side of the bottom wall of the insulating partition 3, and the connecting parts 201 of the third conductive sheet 23 are clamped with the bottom clamping block 302.
[0135] Exemplarily, the bottom clamping block 302 includes: a second vertical clamping section 3021 and a third horizontal clamping section 3022. Among them, the first end of the second vertical clamping section 3021 is connected to the inner side of the bottom wall of the insulating partition 3, and the second end of the second vertical clamping section 3021 is connected to the first end of the third horizontal clamping section 3022. In this way, the third horizontal clamping section 3022, the second vertical clamping section 3021 and the bottom wall of the insulating partition 3 cooperate to form a clamping cavity, and the connecting portion 201 of the third conductive sheet 23 is limited in this clamping cavity.
[0136] When installing the third conductive sheet 23, enter from one of the ports of the accommodating cavity 11, and insert the connecting portions 201 at both ends of the third conductive sheet 23 into the corresponding clamping cavities. After the installation of the third conductive sheet 23 is completed, use the cover plate to block the two ports of the accommodating cavity 11 to protect the components inside the accommodating cavity 11.
[0137] On the other hand, the embodiment of the present disclosure also provides a track socket, as shown in the appendix Figure 7 or the appendix Figure 8 As shown, the track socket includes: an electrical connector 4 and any one of the energized rails described above. Among them, the electrical connector 4 is used to draw power by inserting into the accommodating cavity 11 of the energized rail through the opening 12 of the energized rail.
[0138] For the track socket provided by the embodiment of the present disclosure, based on the smaller thickness of the energized rail used and the better anti-wear effect of each conductive sheet, the track socket not only has a smaller volume but also has a longer service life.
[0139] A plug (not shown) can be led out outside the rail body 1 of the energized rail, for example, at the bottom. The plug has an N-pole lead, an L-pole lead and an E-pole lead. Exemplarily, the L-pole lead and the N-pole lead are electrically connected to the first conductive sheet 21 and the second conductive sheet 22 respectively, and the E-pole lead is electrically connected to the third conductive sheet 23 to form an electrical conduction path between the plug and each conductive sheet.
[0140] In application, by inserting the plug of the energized rail into a fixed socket fixed on a fixed object such as a wall or a tabletop, the fixed socket is used to supply power to the energized rail.
[0141] In some possible implementation manners, as shown in the appendix Figure 7 , the appendix Figure 9 or the appendix Figure 10 As shown, the electrical connector 4 includes: a socket portion 41, a guiding portion 42 and a power-taking portion 43 that are electrically connected in sequence.
[0142] Among them, the socket portion 41 is located outside the rail body 1, as shown in the appendix Figure 9As shown, the socket part 41 includes: a socket housing 411, a socket sleeve (not shown) located inside the socket housing 411, and jacks 412 located at the top of the socket housing 411 and corresponding to the socket sleeve. The plug of an external electrical component can be inserted into the above-mentioned socket sleeve through the jacks 412 to perform insertion and power taking.
[0143] The guiding part 42 is electrically connected to the socket sleeve in the socket sleeve seat 41, and the guiding part 42 penetrates through the opening 12 of the energizing rail and extends into the accommodating cavity 11 (when there is an insulating partition, the guiding part 42 substantially penetrates through the first cavity of the first cavity part 31 and extends into the second cavity of the second cavity part 32). The dimension of the guiding part 42 in the width direction is adapted to the width of the opening 12, and the two are in clearance fit. In this way, when the electrical connector 4 slides along the rail body 1, the guiding part 42 can not only move along the opening 12, but also the inner wall of the opening 12 can support the guiding part 42, so as to ensure that the power taking part 43 is always at the desired position in the accommodating cavity 11.
[0144] As shown in the appendix Figure 9 As shown, the power taking part 43 is located in the accommodating cavity 11 and can rotate in the accommodating cavity 11. The top of the power taking part 43, for example, the middle position at the top, is electrically connected to the guiding part 42. The top parts of the power taking part 43 on both sides of the guiding part 42 respectively have a first contact piece 431 and a second contact piece 432. The first contact piece 431 is used for electrical contact with the first conductive piece 21, and the second contact piece 432 is used for electrical contact with the second conductive piece 22 (see appendix Figure 7 ). The bottom of the power taking part 43 has a third contact piece 433, and the third contact piece 433 is used for electrical contact with the third conductive piece 23 (see appendix Figure 7 ).
[0145] Among them, the first contact piece 431 and the second contact piece 432 are respectively located on both sides of the power taking part 43 along the length direction. The socket sleeve, the guiding part 42, the first contact piece 431, the second contact piece 432 and the third contact piece 433 of the power taking part 43 in the socket part 41 are electrically connected in sequence to form a power taking path.
[0146] In the embodiment of the present disclosure, both the first contact piece 431 and the second contact piece 432 are arranged at the top position of the power taking part 43 and are located in the gap between the top of the power taking part 43 and the bottom of the socket part 41. In this way, the first contact piece 431 and the second contact piece 432 are not easily touched, which not only makes the power use safer, but also the first contact piece 431 and the second contact piece 432 are not easily polluted, which is beneficial to improving the service life of the electrical connector 4.
[0147] Furthermore, in the embodiment of the present disclosure, the power taking part 43 is integrally formed by encapsulation. With such a setting, the power taking part 43 has high strength and is not easily deformed. At the same time, it is also beneficial to reduce the thickness of the power taking part 43.
[0148] When the power - taking part 43 is inserted into the accommodation cavity 11 from the opening 12 of the guide - rail body 1, the length direction of the power - taking part 43 is parallel to the length direction of the opening 12. In this way, it can smoothly pass through the opening 12 and enter the accommodation cavity 11. And at this time, the power - taking part 43 can move along the length direction of the guide - rail body 1 to move to a suitable power - taking position in the non - power - taking state.
[0149] When taking power by using the power - taking part 43 at a specific power - taking position, rotate the power - taking part 43 so that its length direction is perpendicular to the length direction of the opening 12. In this way, the first contact piece 431 and the second contact piece 432 on both sides of the power - taking part 43 are respectively located on both sides of the opening 12, and then make electrical contact with the first conductive piece 21 and the second conductive piece 22 on both sides of the opening 12.
[0150] Further, as shown in the appendix Figure 10 The electrical connector 4 provided by the embodiment of the present disclosure further includes: a chassis 44. Among them, the chassis 44 is rotatably arranged at the bottom of the socket housing of the socket part 41, and a positioning structure, such as a positioning block 441, is arranged at the bottom of the chassis 44. Correspondingly, as shown in the appendix Figure 7 On the top of the guide - rail body 1, that is, on the upper surface of the top plate 101, there is a receiving structure adapted to the limiting structure. For example, a positioning groove 105 adapted to receive the positioning block 441.
[0151] The power - taking part 43 of the electrical connector 4 is inserted into the interior of the accommodation cavity 11, the chassis 44 abuts against the top wall of the guide - rail body 1, and the positioning block 441 on the chassis 44 enters the positioning groove 105 at the top of the guide - rail body 1. In this way, the chassis 44 does not rotate relative to the guide - rail body 1. By rotating the socket part 41, the power - taking part 43 can be driven to rotate relative to the chassis 44, that is, the power - taking part 43 can be driven to rotate relative to the guide - rail body 1, and then the contact state and the non - contact state of each contact piece on it and each conductive piece in the accommodation cavity 11 can be switched.
[0152] There is a rotation locking structure between the chassis 44 and the socket part 41. The rotation locking structure is used to stably position the power - taking part 43 at the power - taking position to avoid unnecessary rotation. As shown in the appendix Figure 10 As shown, a button 45 is arranged on the socket housing of the socket part 41. The button 45 is configured to release the positioning of the rotation locking structure on the power - taking part 43 when being pressed, so that the power - taking part 43 can continue to rotate.
[0153] In some possible implementation manners, as shown in the appendix Figure 9 or in the appendix Figure 10As shown in the figure, the electrical connector 4 provided by the embodiment of the present disclosure further includes: a protective case 46 fixedly connected to the chassis 44, the protective case 46 is used to accommodate the power-taking part 43 in the non-power-taking state, and the shape and structure of the protective case 46 should ensure that it can be inserted into the accommodating cavity 11 through the opening 12.
[0154] When the power-taking part 43 is housed in the protective case 46, the whole formed by the two can enter the accommodating cavity 11 through the opening 12. When the power-taking part 43 rotates, since the protective case 46 is fixedly connected to the chassis 44, the protective case 46 can always stay in place to avoid interfering with the electrical contact of the power-taking part 43.
[0155] The above description is only for the convenience of those skilled in the art to understand the technical solutions of the present disclosure, and is not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
