Description

Technical Field

[0001] This utility model relates to electrical appliances, and in particular to a power rail that can prevent the isolation strip from being installed backwards. Background Technology

[0002] Existing track socket power rails include a track body and two conductive strip assemblies. Each conductive strip assembly includes an insulating strip and a conductive strip. The conductive strip is installed within the insulating strip, which is installed in a mounting groove within the track body. The insulating strip is insulated to isolate the conductive strip from the track body. The two conductive strips are used to connect to the live wire and the neutral wire of the power grid, respectively. For some power rails, the insulating strips corresponding to the two conductive strip assemblies must not be installed in reverse. However, with existing power rails, it is easy to install the two insulating strips in reverse. Utility Model Content

[0030] Reference Figures 1 to 5 A power rail designed to prevent the insulating strip from being installed backwards includes a rail body 100 and two conductive strip assemblies 200. The rail body 100 has two mounting slots 110, and the two conductive strip assemblies 200 are correspondingly arranged in the two mounting slots 110. Each conductive strip assembly 200 includes an insulating strip 210 and a conductive strip 220, with the conductive strip 220 installed within the insulating strip 210, and the insulating strip 210 installed in the corresponding mounting slot 110. The isolation strip 210 is provided with a hooking part 211, and the mounting channel 110 is provided with a hooking engagement part 120 and a clearance groove 130. The isolation strip 210 is hooked to the hooking engagement part 120 through the hooking part 211 to be fixed to the mounting channel 110. The clearance groove 130 is adjacent to the hooking engagement part 120 and is used to make way for and accommodate the hooking part 211. The width L of the hooking part 211 of one conductive strip assembly 200 is greater than the width W of the clearance groove 130 corresponding to the other conductive strip assembly 200.

[0031] In the aforementioned power rail, the isolation strip 210 is connected to the rail body 100 via a hook part 211. By setting the width of the hook part 211 and the width of the clearance groove 130, when two isolation strips 210 are to be installed in reverse, the hook part 211 of one isolation strip 210 cannot fit into the narrower clearance groove 130, thus preventing reverse installation. This structure, used to prevent the isolation strip 210 from being installed in reverse, is simple and easy to implement.

[0032] In this embodiment, the hook part 211 is an L-shaped hook. It is conceivable that the hook part 211 can also be other shapes, such as a T-shaped hook, etc. The hook and fit part 120 can fit into the shape and structure of the hook part 211, as long as the two can hook together.

[0033] In this embodiment, the isolation strip 210 includes a base strip portion 212, a first sidewall portion 213, and a second sidewall portion 214. One end of the first sidewall portion 213 and one end of the second sidewall portion 214 are respectively connected to the two ends of the base strip portion 212 and together form a U-shaped structure. The conductive strip 220 is disposed within the cavity formed by the base strip portion 212, the first sidewall portion 213, and the second sidewall portion 214. The isolation strip 210 with the above structure is simple in structure and easy to implement.

[0034] In this embodiment, the hook portion 211 is disposed on the base strip portion 212, the first side wall portion 213 and the track body 100 are mutually engaged by a first snap-fit ​​structure, and the second side wall portion 214 and the track body 100 are mutually engaged by a second snap-fit ​​structure. With this structure, while the isolation strip 210 is connected via the hook portion 211, two snap-fit ​​structures are configured to connect the side wall portion and the track body 100, making the installation of the isolation strip 210 more stable and accurate.

[0035] In this embodiment, the first snap-fit ​​structure includes a snap-fit ​​strip 310 and a snap-fit ​​groove 320. The snap-fit ​​strip 310 and the snap-fit ​​groove 320 are respectively disposed on the inner wall of the mounting channel 110 and the first side wall portion 213, with the snap-fit ​​strip 310 snapped into the snap-fit ​​groove 320. In this embodiment, the snap-fit ​​strip 310 is disposed on the track body 100 and the snap-fit ​​groove 320 is disposed on the isolation strip 210. In other embodiments, the snap-fit ​​strip 310 may be disposed on the isolation strip 210 and the snap-fit ​​groove 320 may be disposed on the track body 100. The first snap-fit ​​structure adopts the above-described structure, which is simple and easy to implement.

[0036] In this embodiment, the second snap-fit ​​structure includes a notch 330 provided in the second sidewall portion 214 and an extension arm 340 provided in the track body 100, with the extension arm 340 snapping into the notch 330. The aforementioned second snap-fit ​​structure utilizes the extension arm 340 provided in the track body 100 to achieve snap-fit, resulting in a simple structure that is easy to implement.

[0037] In this embodiment, the extendable arm 340 is provided with a beveled end face to form a V-shaped end, and the recess 330 of the second sidewall portion 214 is a V-shaped recess adapted to the shape of the end of the extendable arm 340. Through the above structure, a more robust snap-fit ​​engagement can be formed.

[0038] It is conceivable that the first and second snap-fit ​​structures are not limited to the above-described implementation methods. In this field, there are many other ways to implement snap-fit ​​structures, and those skilled in the art can configure them according to the actual situation.

[0039] In this embodiment, the isolation strip 210 is provided with a first connecting seat 215 and a second connecting seat 216. The two ends of the conductive strip 220 along the width direction are respectively connected to the first connecting seat 215 and the second connecting seat 216, thereby stably fixing the conductive strip 220.

[0040] In this embodiment, the first connecting seat 215 and the second connecting seat 216 are provided with slots adapted to the conductive strip 220. Both ends of the conductive strip 220 along its width direction are respectively inserted into the slots provided in the first connecting seat 215 and the second connecting seat 216. With the above structure, the conductive strip 220 can be structurally and simply fixed. It is conceivable that the conductive strip 220 can also be fixed to the first connecting seat 215 and the second connecting seat 216 using other structures, which can be configured according to actual circumstances.

[0041] In this embodiment, the first connecting seat 215 is disposed at the connection between the base strip portion 212 and the first side wall portion 213, and is integrally disposed with the base strip portion 212 and the first side wall portion 213; the second connecting seat 216 is disposed on the second side wall portion 214, and is integrally disposed with the second side wall portion 214. With the above structure, the overall conductive strip assembly 200 has good structural strength.

[0042] In this embodiment, the conductive strip 220 is inclined and faces the corner area formed between the base strip portion 212 and the second side wall portion 214, thereby facilitating the power-taking arm of the adapter to make contact and connect to the power source.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
