The present invention provides a power busbar bridge structure, which has the following beneficial effects. Through its structural design, the device supports the conductor line row through the insulating support on the installation box, thereby forming a conductor structure. When it is necessary to connect multiple power busbar bridges, the adjacent installation boxes are brought close to each other and squeezed to connect, and then the conductor line row is inserted between the conductor plates on the insulation board, and then the drive screw is screwed, and the drive screw rotates to drive the clamping plate to move inward under the bite action of the door frame. The movement of the clamping plate squeezes the spring, and then the spring squeezes the squeezing block, and the squeezing block squeezes the insulation board, so that the insulation board and the conductor plate and the conductor line row are squeezed against each other to form a conductive path. At the same time, the clamping plate drops into the locking groove of the adjacent installation box, thereby realizing the connection of multiple busbar bridges. Compared with the operation of the prior art that uses bolts and needs to connect the shell, the operation of this structure is relatively simple, and the connection of multiple busbar bridges is realized.

Please refer to Figures 1-2. The present invention provides a technical solution: a power busbar bridge structure, including an installation box 1, an insulating support 2, a conductor line row 3, an extrusion block 4, an insulating plate 5, a conductor plate 6, a spring 7, a gantry 8, a clamping plate 9, a locking groove 10, and a driving screw 11. The installation box 1 is installed with an insulating support 2, and multiple conductor line rows 3 are installed on the insulating support 2. The extrusion block 4 is slidably embedded on the right side of the installation box 1. Multiple insulating plates 5 are connected to the installation and right insulating supports 2. Conductor plates 6 are installed on the adjacent sides of the insulating plates 5 and the conductor line row 3. The conductor plates 6 are in contact with the insulating plates 5 at the upper and lower ends. The outer end of the extrusion block 4 is connected with a spring 7. The right end of the installation box 1 is installed with a gantry 8, and the clamping plate 9 is slidably sleeved on the gantry 8. A locking groove 10 is opened on the right side of the installation box 1. The right end of the clamping plate 9 is embedded in the locking groove 10 at the left end of the adjacent installation box 1. The driving screw 11 is engaged and inserted on the gantry 8, and the lower end of the driving screw 11 is rotatably connected to the clamping plate 9.

In the present invention, the clamping plate 9 is a rectangular plate structure with the right end bent inward, so that the clamping plate 9 with a rectangular structure can limit the locking groove 10 of the adjacent installation box 1 to prevent it from deflecting.

In the present invention, the cross-sections of the two feet of the portal frame 8 are rectangular, thereby playing a guiding role for the clamping plate 9 .

In the present invention, the insulating support 2 is made of an elastic insulating material, and when the extrusion block 4 extrudes the insulating plate 5 and the insulating plate extrudes the conductor line array 3, the position of the conductor line array 3 can be displaced, which facilitates the close extrusion contact between the conductor plate 6 and the conductor line array 3 to achieve electrical connection.

In the present invention, the installation box 1 is a box-shaped structure made of a metal plate, thereby protecting the internal conductor line array. At the same time, the installation box 1 is grounded to prevent electric shock.

In this embodiment:

When in use, the conductor line row 3 is supported by the insulating support 2 on the installation box 1 to form a conductor structure. When multiple power bus bridges need to be connected, the adjacent installation boxes 1 are brought close to each other and squeezed to connect, and then the conductor line row 3 is inserted between the conductor plates 6 on the insulating plate 5, and then the driving screw 11 is screwed. The driving screw 11 rotates and drives the clamping plate 9 to move inward under the bite action of the gantry 8. The movement of the clamping plate 9 squeezes the spring 7, and then the spring 7 squeezes the squeezing block 4, and the squeezing block 4 squeezes the insulating plate 5, so that the insulating plate 5 and the conductor plate 6 and the conductor line row 3 are squeezed against each other to form a conductive path. At the same time, the clamping plate 9 drops into the locking groove 10 of the adjacent installation box 1, thereby realizing the connection of multiple bus bridges.
