In order to improve the positioning accuracy, the first external connection portion 210 is formed with a positioning protrusion 211 extending toward the second external connection portion 220, and the second external connection portion 220 is formed with a positioning groove 221 adapted to the positioning protrusion 211, so as to improve the connection accuracy.

The specific installation process is as follows:

rubber pads 630 are connected to the inner sides of the closed end caps 610, and then the closed end caps 610, the sealing sleeve 510, the closed gland 620, the anti-collision member 800, the annular sealing member 520, and the connecting end caps 700 are sleeved on the outer sides of the hinge member 100, and the flexible buffer member 400 is also sleeved on the outer circumference of the hinge member 100 between the two connecting end caps 700.

The flexible buffer 400 may be a closed ring shape, or may have a notch, so that the installation is convenient.

The two living hinges 120 on the hinge 100 are connected between the connecting jaws 312 of the end hinge 310.

The previously installed components are installed into the connection cavity of the external connector 200 from the tangential direction of the first external connector 210.

Subsequently, the second outer joint part 220 is fixedly connected with the first outer joint part 210, the closed end cover 610 and the closed gland 620 are fixedly connected with the separation inner wall 205 of the second outer joint part 220, the sealing sleeve 510 is fixed between the closed end cover 610 and the closed gland 620, and the necking end of the sealing sleeve 510 is connected with the transition part 130 in an interference fit manner.

In turn, the bump guard 800 is attached to the side wall of the second connecting lumen 202, the connecting end cap 700 is secured to the inner end surface 204 of the outer member 200, and the annular seal 520 is attached between the connecting end cap 700 and the inner end surface 204 of the outer member 200.

In order to improve the sealing effect, after the connection of the connection end cover 700 is completed, sealing rings are also arranged at two ends of the flexible buffer member 400, so that primary sealing with external seawater is realized.

The inner hinge 321 of the peripheral hinge 320 is installed into the installation channel 203, the positioning portion 330 is pushed into the first connection cavity 201 from the end of the outer joint member 200 through the positioning opening 3213 on the peripheral hinge 320, and then the positioning pin 324 is inserted into the positioning hole 333 from the cavity of the inner hinge 321.

The spacer 323 and the outer hinge 322 are then connected to the outer side of the inner hinge 321, respectively.

Finally, the external flanges 910 are respectively sleeved on the corresponding external connectors 200, and a plurality of elastic pull ropes 920 are connected between the two external flanges 910 along the circumferential direction, so that the connection of the whole damping connector 10 is realized.

After the damping connector 10 is installed, the external connectors 200 at the two ends are respectively inserted into the installation structures below the corresponding photovoltaic panel groups 20, so that the damping connector 10 and the photovoltaic panel groups 20 are connected and fixed.

In the description of the above embodiments, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The foregoing is merely illustrative embodiments of the present utility model, and the scope of the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be covered by the present utility model, and the scope of the present utility model shall be defined by the appended claims.
