[0002] The busbar structure of the surface-insulated tube refers to a common passage to which multiple devices are connected in the form of parallel branches.

[0003] For example, the authorization announcement number "CN209088481U" is an insulated tubular busbar structure that is easy to install. A plug-in rod and a plug-in slot are provided to plug and install the first busbar structure and the second busbar structure. A clamping rod, a clamping slot, a movable rod and a first telescopic spring are provided. The first telescopic spring is reset and stretched, and the clamping rod is driven to clamp with the clamping slot through the movable rod to fix the plug-in rod, so that the first busbar structure and the second busbar structure are easy to install, firm and convenient to disassemble and repair. However, the busbar structure needs to be connected with multiple branch sub-wires during use, and the fixation of one branch line requires four elastic structures to fix it. It is more laborious to connect multiple sub-wires, and the elastic structure has poor stability. The force will cause the spring to shake, resulting in swinging at the connection between the sub-wire and the busbar, affecting signal transmission, and then affecting the normal use of the busbar structure, while increasing the difficulty of operating the busbar structure. Summary of the invention

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings: Example

[0020] See also Figure 1-5In the present embodiment, a busbar structure with a surface insulating tube includes a busbar 1 and a surface insulating tube 4. The outer wall of the busbar 1 is fixedly connected to the inner wall of the surface insulating tube 4. The surface insulating tube 4 is made of rubber, which protects the busbar 1 and ensures its voltage resistance. A top plate 5 is fixedly connected to the lower part of the outer wall of the busbar 1. A clamping structure 2 is connected to the front of the top plate 5. Fixed structures 3 are respectively connected to the left and right sides of the front of the top plate 5. A sub-line 6 is plugged into the bottom joint of the busbar 1.

[0021] The clamping structure 2 includes a first straight plate 201 and a screw 202. The rear end face of the first straight plate 201 is fixedly connected to the front face of the top plate 5. The inner wall of the top plate 5 is rotatably connected to the upper part of the outer wall of the screw 202. The screw 202 is rotated by the bearing on the inner wall of the top plate 5. The outer wall of the screw 202 is threadedly connected to a second straight plate 203. The rear end face of the second straight plate 203 is fixedly connected to a clamping plate 204. The top of the screw 202 is fixedly connected to a handle 205. The handle 205 is convenient for driving the screw 202 to rotate. The outer wall notch of the clamping plate 204 is plugged into the outer wall of the sub-line 6.

[0022] The outer wall of the sub-line 6 in the clamping structure 2 is placed in the outer wall groove of the clamping plate 204, and then the connector of the sub-line 6 is plugged into the connector of the busbar 1, and then the handle 205 is turned. The handle 205 is subjected to force to drive the screw 202 to rotate on the inner wall of the first straight plate 201, and the rotating first screw 202 will cause the second straight plate 203 to move upward, and the moving second straight plate 203 moves upward with the clamping plate 204, and then the clamping plate 204 gradually moves upward to press the bottom of the connector of the sub-line 6, so that the sub-line 6 and the busbar 1 are stably connected, and multiple sub-lines are fixed at the same time to ensure stability, ensure the normal use of the busbar structure, and reduce the difficulty of operating the busbar structure.

[0023] The fixing structure 3 includes a bracket 301 and a bolt 302. The rear end face of the bracket 301 is fixedly connected to the front face of the top plate 5. The inner wall of the bracket 301 is plugged into the outer wall of the bolt 302. A ring 303 is sleeved on the rear of the outer wall of the bolt 302. The ring 303 is a steel gasket that can increase the friction between the bolt 302 and the bracket 301 after being pressed against each other. Notches are processed on the left and right sides of the top plate 5 respectively.

[0024] Working principle:

[0025] Busbar structure fixed:

[0026] Make the front side of the bracket 301 fit with the connection surface, then insert the ring 303 into the outer wall of the bolt 302, and then the bolt 302 passes through the bracket 301 and is threadedly connected to the connection surface until the bolt 302 presses the ring 303 against the bracket 301. The fixing of the bracket 301 will fix the top plate 5, and the fixing of the top plate 5 will complete the position fixation of the busbar 1.

[0027] Busbar structure connection:

[0028] Place the outer wall of the sub-line 6 in the outer wall groove of the clamp 204, then plug the connector of the sub-line 6 into the connector of the busbar 1, and then turn the handle 205. The handle 205 is forced to drive the screw 202 to rotate on the inner wall of the first straight plate 201. The rotating first screw 202 will cause the second straight plate 203 to move upward, and the moving second straight plate 203 will move the clamp 204 upward. Then the clamp 204 will gradually move upward to press the bottom of the connector of the sub-line 6, so that the connection between the sub-line 6 and the busbar 1 is stable. Example

[0029] See also Figure 1-5 In this embodiment, a busbar structure with an insulating tube on the surface also includes a vertical plate 7, the bottoms of the two vertical plates 7 are respectively fixedly connected to the left and right ends of the top of the clamping plate 204, and the outer walls of the vertical plates 7 are plugged into the outer wall grooves of the top plate 5.

[0030] Working principle:

[0031] When the clamping plate 204 moves up and down, it will bring the vertical plate 7 to move up and down in the groove of the outer wall of the top plate 5. The vertical plate 7 has a limiting effect on the clamping plate 204 to prevent the clamping plate 204 from changing its position.
