In the specific embodiments of the present application, the power rail 100 is configured to have a flat cuboid shape. The "conductive conductor 2" refers to a bar-shaped structure in which the dimension of the conductor in its main extension direction is greater than the dimensions in other directions. For example, in the following embodiments, the conductive conductor 2 extends along the length direction, and its length is much greater than its width and thickness

Referring to Figure 3 , the track housing 1 is in the shape of a flat cuboid with a hollow interior. In the middle of the surface of the track housing 1, a track opening 11 is formed along its own length direction.

A track cavity 12 is formed through the track housing 1 along its own length direction, and the track cavity 12 is connected to the track opening 11. The track cavity 12 is divided into two left and right chambers, and the two left and right chambers of the track cavity 12 are symmetrically arranged with respect to the axis of the track opening 11.

[0039] Referring to Figure 3 , the number of the insulating brackets 14 is set to two. In the embodiment of the present application, the insulating brackets 14 are made of insulating materials such as plastics. The two insulating brackets 14 are respectively installed in the left and right chambers of the track cavity 12, and the insulating brackets 14 are fixed relative to the track housing 1.

Further, each conductive conductor 2 includes a first arc-shaped portion, a second arc-shaped portion and a U-shaped connecting portion formed as one body, the first arc-shaped portion and the second arc-shaped portion are fixed together via the U-shaped connecting portion, the first arc-shaped portion and the second arc-shaped portion are respectively arranged at both ends of the U-shaped connecting portion, and the ends of the first arc-shaped portion and the second arc-shaped portion away from the U-shaped connecting portion are curved in directions away from each other. That is, the opening of the conductive conductor 2 is horn-shaped, so that the power-taking arm structure of the adapter 200 is more easily contacted and electrically connected with the conductive conductor 2 under the guidance of the first arc-shaped portion and the second arc-shaped portion. When the adapter 200 is inserted into the power rail 100 for power collection, the power-taking arm of the adapter 200 is clamped by the conductive conductor 2, and the conductive conductor 2 and the power-taking arm of the adapter 200 are contacted and electrically connected, so that the power rail 100 supplies power to the adapter 200.

The end cap 7 cooperates with the track housing 1 to clamp the wiring terminal 3, thereby improving the stability of the wiring terminal 3 installed on the power track 100.

[0046] In another achievable manner, the number of the wiring terminal 3 can also be set to one, and one wiring terminal 3 is installed at a position near the end inside the track housing 1.

[0047] Reference Figures 4 - 7 The connection terminal 3 includes a terminal housing 31 and a terminal conductor 32 fixedly installed in the terminal housing 31. One end of the terminal conductor 32 passes through the terminal housing 31, and the other end is placed in the terminal housing 31. The portion of the terminal conductor 32 passing through the terminal housing 31 is inserted into the conductive conductor 2 in the power track 100, thereby achieving contact and electrical connection between the connection terminal 3 and the conductive conductor 2.

[0048] Reference Figures 4 - 6 The terminal housing 31 is a rectangular plate made of insulating materials such as plastic. The terminal housing 31 includes a terminal base 311, a terminal cover plate 312 mounted on the terminal base 311, and a terminal pressing plate 313 mounted on the terminal base 311. The terminal base 311 is provided with a wiring cavity 3111 and a conductor installation cavity 3112 along its own length direction, and the wiring cavity 3111 is connected with the conductor installation cavity 3112. The terminal pressing plate 313 is U-shaped as a whole, and a card hole is provided at the position of the ears on both sides of the terminal base 311. The terminal base 311 corresponds to the two sides of the terminal pressing plate 313. The card holes on the ears on both sides of the terminal pressing plate 313 are engaged with the terminal base 311 to realize the detachable installation of the terminal pressing plate 313 on the terminal base 311, and at this time, the terminal pressing plate 313 is just covered on the open end of the conductor installation cavity 3112 to block and cover the open end of the conductor installation cavity 3112.

[0050] The number of terminal conductors 32 is set to be multiple, refer to Figure 5And Figure 6 In the embodiment of the present application, the number of terminal conductors 32 is set to three. The three terminal conductors 32 are respectively connected to the live wire, neutral wire and ground wire of the power supply to form a live wire terminal conductor 32, a neutral wire terminal conductor 32 and a ground wire terminal conductor 32. The ground wire terminal conductor 32 is placed between the live wire terminal conductor 32 and the neutral wire terminal conductor 32 to increase the distance between the live wire terminal conductor 32 and the neutral wire terminal conductor 32 as much as possible and improve the safety of the terminal 3.

[0051] Refer to Figure 5 And Figure 6 As shown in FIGS. and, six partitions 314 in three groups are arranged in the conductor installation cavity 3112. The three groups of partitions 314 are integrally arranged on the terminal base 311. An accommodation space is formed between two partitions 314 in the same group. That is, the three groups of partitions 314 divide the conductor installation cavity 3112 into three accommodation spaces, which respectively correspond to installing three terminal conductors 32. At the same time, in order to make the structure of the track housing 1 more regular, the two partitions 314 at both ends of the three groups of partitions 314 close to the cavity wall of the conductor installation cavity 3112 are integrated into the cavity wall of the conductor installation cavity 3112, that is, the end partitions 314 are integrated with the terminal base 311. The blocks provided on the terminal base 311 corresponding to the terminal pressing plate 313 are arranged on the outer sides of the two end partitions 314 of the three groups of partitions 314 facing away from each other.

[0052] The two partitions 314 in the same group are arranged in a stepped cavity reduction manner along the direction away from the wiring cavity 3111. The accommodation space between the two partitions 314 includes a frame ring installation cavity 31121 and a connecting piece installation cavity 31122. The non-cavity-reduced part of the partition 314 forms the frame ring installation cavity 31121, and the stepped cavity-reduced part of the partition 314 and the inner side wall part of the terminal base 311 form the connecting piece installation cavity 31122. The projection width of the frame ring installation cavity 31121 on the terminal base 311 is greater than the projection width of the connecting piece installation cavity 31122. The frame ring installation cavity 31121 is placed between the connecting piece installation cavity 31122 and the wiring cavity 3111, and the frame ring installation cavity 31121 communicates with both of them.

[0053] Refer to Figure 5 And Figure 6 As shown in FIGS. and, a first guide plate 9 is integrally formed at the end of the partition 314 close to the wiring cavity. That is, the first guide plate 9 is placed at the connection between the conductor installation cavity 3112 and the wiring cavity 3111, and the first guide plate 9 partially closes the conductor installation cavity 3112. A gap is formed between the first guide plates 9 at the ends of the partitions 314 in the same group to facilitate the power cord to pass through to the conductor installation cavity 3112. The first guide plates 9 at the ends of two adjacent partitions 314 in different groups are integrally formed, and any first guide plate 9 is also integrally formed on the terminal base 311.

[0054] One end of the terminal pressure plate 313 close to the wiring cavity 3111 is integrally formed with a second guide plate 10. When the terminal pressure plate 313 is installed on the terminal base 311, the second guide plate 10 is flush with the first guide plate 9, and the end of the partition plate 314 abuts against the first guide plate 9 and the second guide plate 10. The first guide plate 9, the second guide plate 10, two partition plates 314 in the same group, the stepped surfaces of the two partition plates 314 in the same group, the terminal pressure plate 313 and the terminal base 311 together form a frame ring installation cavity 31121.

[0055] Refer to Figure 5 and Figure 6 For any terminal conductor 32, it includes a conductive connection piece 321, a wiring frame ring 322 and a wiring screw 323. The conductive connection piece 321 is a slender metal plate, which penetrates through one side of the terminal base 311. One end of the conductive connection piece 321 extends into the conductor installation cavity 3112. Further, the conductive connection piece 321 passes through the connection piece installation cavity 31122 in the accommodation space formed by the two partition plates 314 in the same group and extends into the frame ring installation cavity 31121. The other end of the conductive connection piece 321 passes through the terminal base 311 from the side of the conductor installation cavity 3112 far away from the wiring cavity 3111, and the end of the conductive connection piece far away from the terminal base 311 is inserted into the conductive conductor 2 along the extension direction of the conductive conductor 2 to realize the contact electrical connection between the terminal conductor 32 and the conductive conductor 2.

[0056] The wiring frame ring 322 is made of a conductive material, preferably copper. Its cross-section is a rectangular frame. The wiring frame ring 322 is placed in the conductor installation cavity 3112. Further, the wiring frame ring 322 is placed in the frame ring installation cavity 31121 in the accommodation space formed by the two partition plates 314 in the same group, and the wiring frame ring 322 is sleeved on the end of the conductive connection piece 321 in a clearance fit manner. The two partition plates 314 in the same group clamp and limit the width direction of the wiring frame ring 322 to prevent the wiring frame ring 322 from rotating itself. The stepped cavity walls of the first guide plate 9, the second guide plate 10 and the two partition plates 314 abut against both ends of the wiring frame ring 322 respectively to clamp and limit the length direction of the wiring frame ring 322 to prevent the wiring frame ring 322 from rotating itself. The frame ring installation cavity 31121 limits the circumferential direction of the wiring frame ring 322, so that the wiring frame ring 322 can only move in the frame ring installation cavity 31121 in a direction away from or close to the terminal base 311, maintaining the stability of the movement of the wiring frame ring 322.

[0057] A wiring screw 323 is threadedly connected to the side of the wiring frame ring 322 away from the terminal base 311. By rotating the wiring screw 323 forward or backward, the side of the wiring frame ring 322 opposite to the wiring screw 323 can move in a direction close to or away from the conductive connection piece 321, realizing the wiring of the terminal 3.

[0058] Refer to Figures 5 - 7, Further, the wiring screw 323 includes a screw head 3231, a screw pad 3232 and a screw rod 3233. The screw head 3231, the screw pad 3232 and the screw rod 3233 are integrally arranged. The screw pad 3232 is integrally formed at one end of the screw head 3231, and the screw rod 3233 is integrally formed on the side of the screw pad 3232 away from the screw head 3231, and the screw head 3231, the screw pad 3232 and the screw rod 3233 are coaxially arranged.

[0059] Refer to Figures 5 - 7 , corresponding to the three accommodation spaces on the terminal pressing plate 313, a rotation cavity 3131 and a screw limiting cavity 3132 are formed by opening. The rotation cavity 3131 is opened through the terminal pressing plate 313. The screw limiting cavity 3132 is opened on the side of the terminal pressing plate 313 close to the conductor installation cavity 3112 and is coaxially arranged with the rotation cavity 3131. Both the screw limiting cavity 3132 and the rotation cavity 3131 are disc-shaped cavities, and the cross-sectional diameter of the screw limiting cavity 3132 is larger than the cross-sectional diameter of the rotation cavity 3131. In this way, a stepped surface is formed at the transition position between the screw limiting cavity 3132 and the rotation cavity 3131.

[0060] Refer to Figures 5 - 7 , when the terminal pressing plate 313 is clamped and installed on the terminal base 311, the screw head 3231 is placed in the rotation cavity 3131, the screw pad 3232 is placed in the screw limiting cavity 3132, and the end of the screw rod 3233 away from the screw pad 3232 abuts against the conductive connection piece 321. In this way, the conductive connection piece 321 and the terminal pressing plate 313 jointly limit the wiring screw 323 in the axial direction, so that the wiring screw 323 is only rotatably installed on the terminal base 311.

[0061] Refer to Figure 6 and Figure 7 , when wiring the terminal 3, a screwdriver is used to rotate the screw head 3231 through the opening end of the rotation cavity 3131 away from the screw limiting cavity 3132. The screw head 3231 drives the screw pad 3232 and the screw rod 3233 to rotate. Under the limiting action of the pressing plate on the screw pad 3232 and the limiting action of the frame ring installation cavity 31121 on the wiring frame ring 322, the screw rod 3233 lifts or presses the wiring frame ring 322, so that the side of the wiring frame ring 322 away from the screw head 3231 moves in the direction of approaching or departing from the conductive connection piece 321, thereby clamping the power cord and realizing the power connection of the terminal 3.

[0062] Refer to Figure 5 , to further improve the stability of the wiring screw 323 during rotation, a rotation stability groove 6 is also provided at the position of the conductive connection piece 321 corresponding to the end of the screw rod 3233. The end of the screw rod 3233 away from the screw head 3231 is always placed in the rotation stability groove 6 and rotates in the rotation stability groove 6.

[0063] Reference Figure 6 and Figure 7 When wiring the terminal 3, use a screwdriver to rotate the screw counterclockwise, so that the wiring frame ring 322 moves away from the side of the screw head 3231 and away from the conductive connection piece 321, and a wiring space is formed between the wiring frame ring 322 and the conductive connection piece 321. Then insert the power cord into this wiring space. Use the screwdriver to rotate the screw clockwise again, so that the side of the wiring frame ring 322 away from the rotation cavity 3131 moves towards the conductive connection piece 321, and the wiring frame ring 322 cooperates with the conductive connection piece 321 to clamp the power wire, realizing the power connection of the terminal conductor 32.

[0064] Reference Figure 5 and Figure 6 The ground wire terminal conductor 32 is arranged between the live wire terminal conductor 32 and the neutral wire terminal conductor 32. A ground wire installation cavity is also formed on the terminal base 311, and the part of the conductive connection piece 321 of the ground wire terminal conductor 32 extending out of the terminal base 311 is placed in the ground wire installation cavity. A grounding connecting piece 4 is threadedly connected to the conductive connection piece 321 of the ground wire terminal conductor 32. The grounding connecting piece 4 can be a screw. Connecting holes are provided on both the track housing 1 and the terminal base 311. The grounding connecting piece 4 passes through and connects the connecting holes of the track housing 1, the ground wire conductive connection piece 321, and the terminal base 311 in sequence. Since the opening of the connecting hole destroys the oxidation insulation layer on the surface of the track housing 1, the grounding connecting piece 4 passes through the connecting hole to realize the electrical connection between the track housing 1 and the ground wire terminal conductor 32, realizing the grounding of the track housing 1. At the same time, the grounding connecting piece 4 connects and locks the terminal conductor 32, the track housing 1, and the terminal base 311, realizing the stable installation of the ground wire terminal conductor 32 on the terminal base 311 and improving the stability of the installation of the terminal 3 on the track housing 1.

[0065] Reference Figure 5 and Figure 6 Furthermore, a grounding arch-shaped elastic piece 5 is also arranged on the conductive connection piece 321. The grounding arch-shaped elastic piece 5 is an arch-shaped conductor, and its length direction is distributed along the length direction of the conductive connection piece 321. One end of the grounding arch-shaped elastic piece 5 is provided with a semi-circular arc groove to avoid the grounding connecting piece 4, and the other end of the grounding arch-shaped elastic piece 5 is bent and wrapped around the end of the conductive connection piece 321 to improve the stability of the grounding arch-shaped elastic piece 5 and the conductive connection piece 321. When the grounding arch-shaped elastic piece 5 is sleeved and installed at the end of the conductive connection piece 321, the two ends of the grounding arch-shaped elastic piece 5 are also embedded and installed in the ground wire installation cavity to keep the grounding arch-shaped elastic piece 5 and the conductive connection piece 321 laterally flush.

[0066] The protruding direction of the grounding arched elastic piece 5 is along the direction away from the conductive connection piece 321 to improve the connection stability between the grounding arched elastic piece 5 and the track housing 1. The physical position of the track housing 1 facing the track opening 11 is used to break the oxide insulation layer by laser, so that the track housing 1 forms a conductive path, and the track housing 1 itself is used as the ground wire conductive conductor 2. When the terminal 3 is installed on the track housing 1, the protruding part of the grounding arched elastic piece 5 contacts the conductive path on the track housing 1, realizing the connection between the terminal 3 and the ground wire conductive conductor 2.

[0067] The implementation principle of the embodiment of the present application is as follows: When wiring the terminal 3, first remove the terminal cover plate 312 from the terminal base 311, and then rotate the wiring screw 323 through the opening end of the rotation cavity 3131 away from the screw limiting cavity 3132. The wiring screw 323 presses down on the wiring frame ring 322, and a wiring space is formed between the wiring frame ring 322 and the conductive connection piece 321. The power cord is inserted into the wiring space through the conductor installation cavity 3112, and then the wiring screw 323 is rotated in the reverse direction. The wiring screw 323 pulls up the wiring frame ring 322, so that the side of the wiring frame ring 322 away from the screw head 3231 moves towards the direction close to the conductive connection piece 321 until the wiring space disappears, and the power cord is clamped between the conductive connection piece 321 and the wiring frame ring 322. Finally, the terminal cover plate 312 is reinstalled on the terminal base 311 to complete the wiring of the terminal 3.

[0068] During the wiring process of the above terminal 3, the axis direction of the wiring screw 323 remains stationary, and the wiring frame ring 322 is pulled and moved along the axis direction by the wiring screw 323. The stationary state of the axis direction of the wiring screw 323 is more convenient for the wiring personnel to rotate it, improving the wiring convenience of the terminal 3. The terminal base 311 and the terminal pressing plate 313 cooperate with each other to limit the extreme separation distance between the wiring screw 323 and the wiring frame ring 322, preventing them from separating and improving the problem of inconvenient wiring of the terminal.

[0069] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
