The conductive rail telescopic connector is composed of a conductive copper strip, a sliding core plate and a core plate cover plate as the core part, and a rail body transition plate nested in the sliding core plate and fixed in the center position and a socket rail body nested in both ends of the sliding core plate and telescopically slid to form a complete expansion and telescopic head. The conductive copper strip has a middle rigid section and an S-shaped flexible section that is telescopic at both ends. The rigid section is superimposed with the sliding core plate and the core plate cover plate as a whole. The rail body transition plate is nested in the sliding core plate, and the socket rail body is nested in both ends of the sliding core plate; the end of the flexible section of the conductive copper strip is connected to the socket rail body. The above-mentioned conductive rail telescopic connector can flexibly telescope and slide while maintaining good conductivity between adjacent conductive rails, and can reduce the installation space and meet the insulation spacing requirements in a highly integrated environment.

[0044] Example:

[0045] Please refer to Figure 2-Figure 5This embodiment provides a conductive rail assembly 010, which includes a plurality of conductive rails 200 and a plurality of conductive rail connectors 100; the plurality of conductive rails 200 are connected end to end in sequence, and the conductive rail connector 100 is arranged between the ends of two adjacent conductive rails 200, and is used to connect the two conductive rails 200 so that electricity can be supplied between the conductive rails 200.

[0046] The conductive rail connector 100 includes a transition plate 110, a sliding core plate 120 and a conductive strip 130. The transition plate 110 is arranged in the gap between the ends of adjacent conductive rails 200. The rail vehicle can travel from one conductive rail 200 to another conductive rail 200 through the above-mentioned transition plate 110. The sliding core plate 120 is a strip plate, the length of which is greater than the length of the transition plate 110, and is located below the transition plate 110 (with a normal use state as a reference). The sliding core plate 120 is arranged parallel to the transition plate 110 and is connected to form a whole through a connecting piece. In this embodiment, a screw is respectively arranged at both ends of the transition core plate, and the screw connects the transition plate 110 with the sliding core plate 120.

[0047] The conductive belt 130 extends along the length direction of the sliding core plate 120, and its length is greater than the length of the sliding core plate 120. The conductive belt 130 includes a middle connecting portion 134 and two end connecting portions 132, the middle connecting portion 134 is used to connect to the sliding core plate 120, and the two end connecting portions 132 are respectively connected to two conductive rails 200. A bending section is respectively provided between the two end connecting portions 132 and the middle connecting portion 134, and the above bending section forms a wave shape, so that the end connecting portions 132 and the middle connecting portion 134 can move closer to or away from each other within a certain range. In this embodiment, the conductive belt 130 is made of soft copper belt; in other embodiments, the conductive belt 130 supported by other conductive materials can also be used.

[0048] The conductive rail 200 is in the shape of a rectangular parallelepiped as a whole, and a mounting groove 210 is provided at the bottom thereof, and the mounting groove 210 extends along the length direction of the conductive rail 200; slide grooves 220 are respectively provided on the two side walls of the mounting groove 210. The sliding core plate 120 and the conductive belt 130 are assembled in the mounting groove 210, and the two side edges of the sliding core plate 120 are respectively slidably disposed in the two slide grooves 220.

[0049] In this embodiment, the sliding core plate 120 is made of non-metallic material, and the conductive rail 200 is made of metallic material as a whole. The above design reduces the friction between the sliding core plate 120 and the conductive rail 200, and prevents adhesion from occurring.

[0050] In order to improve the rigidity of the middle connecting portion 134 of the conductive belt 130 and the sliding core plate 120, a core plate cover plate 140 is also provided on the upper surface of the sliding core plate 120; the core plate cover plate 140 adopts a metal plate. Specifically, a strip groove extending along the length direction is provided on the sliding core plate 120, and the core plate cover plate 140 is embedded in the above-mentioned strip groove. The core plate cover plate 140 is provided with screw holes arranged in a matrix, and the core plate cover plate 140 is connected to the sliding core plate 120 by screws. After the conductive rail 200 is connected and assembled with the conductive rail 200, a gap is set between the upper surface of the core plate cover plate 140 and the bottom surface of the mounting groove 210 of the conductive rail 200.

[0051] Furthermore, in order to improve the stability of the rail vehicle when passing through the guide rail connection and reduce vibration and noise; a triangular notch 230 is provided at the end of the conductive rail 200, and correspondingly, the transition plate 110 is roughly a diamond structure, which includes two triangular connecting ends 112. During assembly, the two connecting ends 112 of the transition plate 110 are respectively embedded in the two triangular notches, and the edges of the connecting ends 112 of the transition plate 110 are arranged parallel to the edges of the notches. Due to the adoption of the above structure, when the distance between the two guide rails in their length direction is L, the distance of relative movement between the edge of the transition plate 110 and the edge of the notch is L*sinα (where Alpha is the angle between the edge of the notch and the length direction of the conductive rail 200). The size of the gap between the transition plate 110 and the guide rail plate directly affects the stability, vibration and noise of the rail vehicle; therefore, after adopting the above structure, the change amplitude of the gap between the transition plate 110 and the guide rail plate is less than the distance of relative movement of the two guide rails in the length direction, thereby effectively improving stability and reducing vibration and noise.

[0052] In addition, an insulating support device 300 is provided in the middle of the conductive rail connector 100; the upper end of the insulating support device 300 is connected to the conductive belt 130, the sliding core plate 120 and the core plate cover plate 140 by screws, and the lower end is used for installation and fixing.

[0053] The conductive rail assembly provided by this embodiment has the following beneficial effects: after adopting the conductive rail connector, adjacent conductive rails can be energized; and the sliding core plate can be embedded in the conductive rail, so that the thickness of the conductive rail connector is relatively small, thereby reducing the installation space. In addition, the transition plate and the conductive rail running surface are highly coplanar, which can effectively keep the current delivery working surface smooth and continuous, and the current collector passes through the expansion joint smoothly, without jumping or abnormal sound, and can also achieve flexible expansion and contraction in the curved section of the line.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
