A sliding conductive rail and a conductive device using the same

Abstract

The present invention discloses a sliding conductive rail and a conductive device using the rail. The sliding conductive rail comprises a rail base, a conductive strip, an elastic conductive contactor and a segmented conductive film. The conductive strip is installed on the rail base, and the elastic conductive contactor is installed on the rail base and contacts the segmented conductive film. When positive pressure is applied to the segmented conductive film, the elastic conductive contactor connects the segmented conductive film and the conductive strip. The segmented conductive film is connected by an elastic wire contactor. When the rail leaves, the segmented conductive film is separated from the conductive strip under the elastic action, and the conductive strip is not charged, so the safety is guaranteed.

Description

Technical Field

[0001] The invention relates to the technical field of conductive rails, and in particular to a sliding conductive rail and a conductive device using the rail. Background Art

[0002] The busbar is a mobile power supply device, which contacts the brushes and supplies power to them. It is mainly used for workshop hoisting, assembly line production, and mobile power supply for various bridge cranes, gantry cranes, and trams at stations and docks.

[0003] Among them, the sliding conductive track is a component of the busbar. At present, there are basically two ways of mobile conduction, using a cable plus drag chain structure and a charged slide rail structure. The cable plus drag chain structure is relatively complex and expensive. The drag chain is installed outside, which not only takes up space, but also may cause safety hazards. At present, the electric slide rail structure basically uses at least two conductive strips and carbon brushes to form a conductive circuit in the conductive part. However, because the conductive strips are distributed horizontally along the guide rail and exist vertically, they cannot be completely insulated from the external environment. The entire conductive strip is charged, which poses a safety hazard after leaving the track. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a sliding conductive rail, which uses an elastic contactor to connect the segmented conductive film and the conductive strip. When the rail is moved away, the segmented conductive film and the conductive strip are separated under the action of elasticity, the conductive strip is not electrified, and safety is guaranteed.

[0005] The present invention is achieved through the following technical solutions:

[0006] A sliding conductive rail comprises a rail base, a conductive strip, an elastic contactor and a segmented conductive film; the elastic contactor is installed in the rail base, the conductive strip and the segmented conductive film are installed on both sides of the elastic contactor respectively, and when positive pressure is applied to press the segmented conductive film, the elastic contactor is deformed and connects the segmented conductive film and the conductive strip.

[0007] Furthermore, the segmented conductive film includes a film body and a conductive region and an insulating region located on the film body, and adjacent conductive regions are connected via an insulating region made of insulating material.

[0008] Furthermore, the conductive areas are distributed at equal intervals along the axial direction of the slide rail base, and are distributed in a manner consistent with the conductive strips along the lateral direction of the slide rail base.

[0009] Furthermore, the elastic contactor comprises a contact piece and an elastic piece, and the elastic piece is insulated and connected to the slide rail base. Under the support of the elastic contactor, the segmented conductive film is not in contact with the conductive strip.

[0010] Furthermore, the elastic member is located at two ends of the contact member, and the elastic member and the slide rail base are made of insulating material.

[0011] Furthermore, the contact member is arranged perpendicular to the conductive strip, and a lower surface thereof is in contact with the segmented conductive film.

[0012] Furthermore, the conductive strip is one or more.

[0013] Another object of the present invention is to provide a sliding conductive device, comprising the sliding conductive rail as described above, and also comprising a conductive slider, wherein the conductive slider is installed on the sliding conductive rail, and the conductive part of the conductive slider is in contact with the sliding conductive rail.

[0014] Furthermore, the conductive slider includes a slider base, a guide wheel, and a conductive brush. The conductive brush is in close contact with the segmented conductive film. The guide wheel is made of insulating material and is used to press the segmented conductive film so that the segmented conductive film is connected to the conductive strip through the elastic contactor.

[0015] Furthermore, the axial width of the conductive brush along the slide rail base is greater than the width of the segmented conductive film insulating area, so that the conductive brush can contact two conductive areas simultaneously along the axial direction.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, an elastic contactor is used to connect the segmented conductive film. When the slide rail leaves, the segmented conductive film is separated from the conductive strip under the action of elasticity, and the conductive film is not charged, so the safety is guaranteed.

[0027] Example 1

[0028] See also Figure 1-4 A sliding conductive rail comprises a rail base 1, a conductive strip 2, an elastic contactor 3 and a segmented conductive film 4; the elastic contactor 3 is installed in the rail base 1, the conductive strip 2 and the segmented conductive film 4 are respectively installed on both sides of the elastic contactor 3, and when positive pressure is applied to press the segmented conductive film 4, the elastic contactor 3 connects the segmented conductive film 4 and the conductive strip 2.

[0029] In the sliding conductive rail of the present invention, an elastic contactor 3 is used to connect the conductive strip 2 with the segmented conductive film 4. When the segmented conductive film 4 is pressed tightly (specifically, pressure is applied by a conductive brush), the elastic contactor 3 will be deformed, and the position where the segmented conductive film receives positive pressure will contact the conductive strip, connecting the segmented conductive film 4 and the conductive strip 2 to form a conductive loop; when the rail leaves, under the action of elasticity, the conductive part of the elastic contactor 3 is separated from the conductive strip 2, causing the segmented conductive film 4 to be separated from the conductive strip 2, the loop is disconnected, the conductive strip is not electrified, and safety is guaranteed.

[0030] like Figure 3 As shown, in one embodiment of the present invention:

[0031] The segmented conductive film 4 includes a film body 401 and conductive regions 402 and insulating regions 403 located on the film body 401 . Adjacent conductive regions 402 are connected via the insulating regions 403 made of insulating material.

[0032] In a specific embodiment, the conductive areas 402 are distributed at a certain distance along the axial direction of the slide rail base 1 , and are distributed in a consistent manner with the conductive strips 2 along the lateral direction of the slide rail base 1 .

[0033] The conductive area 402 is arranged reasonably so as to achieve contact connection between the elastic contactor 3 and the conductive area 402 .

[0034] like Figure 4 As shown, in one embodiment of the present invention:

[0035] The elastic contactor 3 includes a contact member 302 and an elastic member 301. The elastic member 301 is insulated and connected to the rail base 1. Under the support of the elastic contactor 3, the segmented conductive film 4 is not in contact with the conductive strip 2. The contact member 302 is conductive to the corresponding part of the conductive strip 2, and the non-corresponding part is insulated.

[0036] The elastic member 301 is located at two ends of the contact member 302 , and the elastic member 301 and the slide rail base 1 are made of insulating materials.

[0037] The contact member 302 is arranged perpendicular to the conductive strip 2 , and its lower surface is in contact with the segmented conductive film 4 .

[0038] The conductive strip 2 may be one or more conductive strips. Specifically, the number of conductive strips 2 may be adjusted by the user according to the situation.

[0039] Example 2

[0040] like Figure 5As shown, a sliding conductive device includes the above-mentioned sliding conductive rail, and also includes a conductive slider 5, wherein the conductive slider 5 is installed on the sliding conductive rail, and the conductive part of the conductive slider 5 contacts the sliding conductive rail. After the conductive slider 5 is installed, the contact surface is sealed and isolated from the outside.

[0041] like Figure 6 As shown, in this embodiment:

[0042] The conductive slider 5 comprises a slider base 501, a guide wheel 502, and a conductive brush 503. The guide wheel 502 is used to press the segmented conductive film 4 so that the segmented conductive film 4 is connected to the conductive strip 2 through the elastic contactor 3. The conductive brush 503 is in close contact with the segmented conductive film 4.

[0043] Specifically, the slider base 501 is made of insulating material, and the guide wheel 502 is made of insulating material.

[0044] In a specific embodiment, the axial width of the conductive brush 503 along the rail base 1 is greater than the width of the insulating region 403 of the segmented conductive film 4, so that the conductive brush 503 can contact two conductive regions 402 simultaneously along the axial direction.

[0045] By controlling the length of the conductive region 402 of the segmented conductive film 4 , it is possible to achieve continuous conduction of the conductive strip 2 through the segmented conductive film 4 .

[0046] It should be noted that the width of the conductive brush 503 and the compression range of the guide wheel 502 cannot cause the area outside the seal of the conductive slide rail base 1 to be compressed and connected to the conductive strip 2 through the elastic contactor 3, causing safety hazards.

[0047] Although the present invention discloses embodiments and drawings, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
