Description

Technical Field

[0001] This utility model relates to the field of track systems, and in particular to a two-loop track system. Background Technology

[0002] The track system includes a conductive slide rail and a light assembly that can be slidably mounted on the conductive slide rail. The light assembly can be adjusted to different positions on the conductive slide rail and is generally used in clothing stores, car showrooms, jewelry stores, hotels, and other locations where lighting is required, thereby facilitating illumination.

[0003] Existing designs typically use two wires per circuit or four wires per circuit. One circuit (i.e., live wire + neutral wire) and two circuits (usually two live wires + two neutral wires, or two live wires + one neutral wire + one ground wire) are common.

[0004] However, some regulations require that both circuits must be grounded (although some do not). Therefore, how to simplify the structure and achieve the above functions is one of the key design considerations. Thus, how to design the layout while facilitating assembly is the key to slide rail design.

[0005] For example, Chinese patent 202022767283.6 adopts a two-wire, one-loop structure. Utility Model Content

[0006] The main purpose of this utility model is to propose a two-circuit track system, which aims to design a three-wire two-circuit system that meets the grounding requirements, while having a simple and stable structure and is easy to assemble.

[0007] To achieve the above objectives, this utility model proposes a two-loop track system, comprising:

[0008] The slide rail is a cavity with an opening at the lower end. The slide rail is made of metal. The left and right sides of the cavity are respectively provided with a first slot and a second slot, and a third slot is provided below the second slot.

[0009] A conductive component, comprising a plastic part and a conductive strip clipped onto the plastic part, the conductive component including a first live wire component, a second live wire component, and a neutral wire component.

[0010] The first live wire assembly, the second live wire assembly, and the neutral wire assembly are respectively installed in the first slot, the second slot, and the third slot.

[0011] The outer wall of the slide rail is coated with an insulating layer, and the inner wall of the slide rail is provided with a grounding terminal that is not insulated, and the grounding terminal extends along the length of the slide rail.

[0012] The slide rail is equipped with insulating plugs at both ends.

[0013] This design has the following advantages:

[0014] 1. By setting a grounding terminal through a non-insulating layer on the slide rail and ensuring the insulation effect of the outer wall through an insulating layer, the existing design circuit is effectively simplified.

[0015] 2. A dual-circuit design was achieved through a reasonable layout: the first live wire assembly and the neutral wire assembly form the first circuit, and the second live wire assembly and the neutral wire assembly form the second circuit. The use of the same neutral wire assembly enabled the switching control of both sets of lamps.

[0016] For example, in a shopping mall, when the daytime lighting is good, the first circuit (with N light fixtures) is used; when the daytime lighting is poor, the second circuit (with 2N light fixtures) is used.

[0017] At night, both the first and second circuits are turned on to meet different lighting needs. Attached Figure Description

[0034] like Figures 1 to 4 As shown, a dual-loop orbital system includes:

[0035] The slide rail 1 is a cavity 12 with an opening 11 at the lower end. The slide rail 1 is made of metal. The left and right sides of the cavity 12 are respectively provided with a first slot 31 and a second slot 32. A third slot 33 is provided below the second slot 32.

[0036] A conductive component, comprising a plastic part and a conductive strip clipped onto the plastic part, the conductive component including a first live wire component 21, a second live wire component 22, and a neutral wire component 23.

[0037] The first live wire assembly 21, the second live wire assembly 22, and the neutral wire assembly 23 are respectively installed in the first slot 31, the second slot 32, and the third slot 33.

[0038] The outer wall of the slide rail 1 is coated with an insulating layer, and the inner wall of the slide rail 1 is provided with a non-insulating grounding terminal 4, which extends along the length of the slide rail 1.

[0039] Insulating plugs are provided at both ends of the slide rail 1.

[0040] This design has the following advantages:

[0041] 1. By setting a grounding terminal in slide rail 1 through a non-insulating layer and ensuring the insulation effect of the outer wall through an insulating layer, the existing design circuit is effectively simplified.

[0042] 2. A dual-circuit design was achieved through a reasonable layout. The first live wire assembly 21 and the neutral wire assembly 23 form the first circuit, while the second live wire assembly 22 and the neutral wire assembly 23 form the second circuit. The use of the same neutral wire assembly 23 enables the switching control of both sets of lamp assemblies.

[0043] For example, in a shopping mall, when the daytime lighting is good, the first circuit (with N light fixtures) is used; when the daytime lighting is poor, the second circuit (with 2N light fixtures) is used.

[0044] At night, both the first and second circuits are turned on to meet different lighting needs.

[0045] Specifically, the conductive strip includes a first conductive strip, a second conductive strip, and a third conductive strip. The first conductive strip, the second conductive strip, and the third conductive strip are elongated sheet-like structures and are all vertically arranged, thereby fitting the spring sheet structure of the lamp assembly.

[0046] In this embodiment of the utility model, the plastic part includes a first plastic part 511, a second plastic part 512, and a third plastic part 513.

[0047] Specifically, the first fire wire component 21 and the second fire wire component 22 are arranged opposite to each other.

[0048] In this embodiment of the invention, the first plastic part and the second plastic part have the same structure.

[0049] It includes a first main body 61, a first limiting part 62 extending from the lower part of the first main body 61 to both sides, and a first insertion groove 63 recessed from the upper wall of the first main body 61.

[0050] The bottom wall of the first insertion slot 63 extends horizontally to form the first insertion slot 63.

[0051] The first positioning groove 64 is used to install the second conductive strip / third conductive strip;

[0052] The first slot 31 / second slot 32 is provided with a first limiting groove 65 that cooperates with the first limiting part 62, thereby realizing the assembly of the first wire assembly 21 and the second wire assembly 22.

[0053] During assembly, the first fire wire assembly 21 and the second fire wire assembly 22 are slid into the slide rail 1 from either end.

[0054] In addition, the insertion slot can limit the movement of the spring piece and also serve as a protective feature.

[0055] Specifically, the first main body 61 is provided with a clearance groove in the middle, which facilitates the deformation of the first limiting part 62 when it is engaged, thus avoiding the problem of hard engagement.

[0056] In this embodiment of the present invention, a protrusion is provided on either side of the first limiting part 62. The protrusion abuts against the wall of the first limiting groove, thereby reducing friction when sliding in and facilitating assembly.

[0057] Specifically, the third plastic part includes a third body 7, a second limiting portion 71 extending from the lower wall of the third body 7, and a third limiting portion 72 extending from the third body 7.

[0058] The third limiting part and the third limiting part are arranged adjacent to each other on both sides of the cavity 12; the wall surface of the third main body 7 is provided with a third insertion groove, and the rear end of the third insertion groove extends horizontally with a third positioning groove, which is used to install the third conductive strip.

[0059] The third slot 33 is provided with a third limiting groove and a third limiting part that cooperate with the third limiting part. The third limiting part is a hook structure, which realizes the installation and fixation of the third plastic part. The hook structure of the third limiting part can reduce the contact area while ensuring the stability of the installation.

[0060] In this embodiment of the utility model, the grounding terminal 4 is provided at the opening 11 of the cavity 12 or at the bottom wall position of the cavity 12, which can be set according to actual needs.

[0061] Specifically, the two sides of the first main body 61 are inclined surfaces 8, which serve to avoid obstacles in order to install the third plastic part.

[0062] The slide rail 1 is preferably made of aluminum alloy.

[0063] The sheet-like structure can provide more stable current and contact area.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
