[0002] The busbar is a power supply device for mobile equipment, which is used to ensure that the mobile equipment maintains conductive contact during movement. It is widely used in lifting machinery in workshop lifting, assembly line production, port freight and other occasions.

[0003] The busbar is generally suspended by a suspension frame. The busbar is usually long. After being used for a period of time without a tensioning device, it will be stretched to a certain extent, causing a slight deformation of the busbar. The deformation may cause poor contact of the conductor on the busbar, thus affecting normal operation.

[0004] The tensioner is a tensioning device that connects the busbar and the power supply. The existing tensioning device, as recorded in "CN201320701311.1 A new type of power supply tensioner for busbar", has the following shortcomings: there is a lack of protective structure at the power connector, so there is a risk of the power connector being exposed. After long-term use, the connector may experience aging, rust and other problems, which will affect the overall operation of the busbar.

[0029] The specific implementation modes of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0030] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components. Example 1

[0032] In this embodiment, as a specific solution, the flat tensioner body 1 is divided into a main body area 11 and a wiring area 12, and the connecting section 41 of the cover shell 4 is installed on the wiring area 12; one end of the main body area 11 is an open structure, and the other end is a closed structure, and a plurality of through holes 13 are provided in the main body area 11, and a metal conductive sheet 5 is provided in the through hole 13, and the metal conductive sheet 5 extends to the wiring area 12, and the wiring area 12 is provided with a wiring terminal 6, and the wiring terminal 6 is connected to the metal conductive sheet 5; the front and back sides of the main body area 11 are also respectively provided with a plurality of fastening bolt holes 14, and the wiring area 12 is provided with a plurality of partitions 15 corresponding to the positions of the through holes 13; the partition 15 can separate each wiring terminal 6, which is helpful for subsequent regular wiring.

[0033] In this embodiment, as a specific solution, a quick-plug edge 16 is provided at the overlap of the wiring area 12 and the main body area 11, and the connecting section 41 of the cover shell 4 is clamped on the quick-plug edge 16 and fixed with screws.

[0034] More specifically, protrusion structures 17 are respectively provided on both sides of the wiring area 12. The protrusion structure 17 and the quick plug-in edge 16 form an integral U-shaped structure, and the connecting section 41 of the cover shell 4 is clamped on the U-shaped structure.

[0035] More specifically, the wiring area 12 is further provided with a limiting block 18 on the side of the protruding block structure 17; when the connecting section 41 of the cover shell 4 is clamped onto the U-shaped structure, the limiting block 18 has a limiting and squeezing effect on the cover shell 4 from both sides.

[0036] More specifically, a clamping block structure 19 is disposed above the quick plug-in edge 16 , and the clamping block structure 19 clamps the connecting section 41 of the cover shell 4 .
