[0024] The plug assembly 2 and the socket assembly 3 are both connected to a flexible circuit board 1. The ends of the flexible circuit board 1 that connect the plug assembly 2 and the socket assembly 3 are provided with multiple plug contacts 23 and multiple socket contacts 33 corresponding to conductors 12. The conductors 12 are inserted into the opposite ends of the plug contacts 23 and the socket assembly 3. The plug contacts 23 and the socket contacts 33 are electrically connected to the conductive lines on the flexible circuit board 1 through the conductors 12.

[0025] This application achieves a detachable design between the plug assembly 2 and the socket assembly 3 and the flexible circuit board 1 by inserting the plug contact 23 and the socket contact 33 into the conductor 12. The detachable structure allows the flexible circuit board 1 and the plug assembly 2 or socket assembly 3 to be separated. During installation, the two parts can be disassembled. The plug assembly 2 or socket assembly 3 is installed outside the compartment, and the flexible circuit board 1 is inserted into the plug assembly 2 and socket assembly 3 inside the compartment, thereby improving the repair and maintenance of the flexible electrical connector.

[0026] One end of the plug contact 23 is a socket structure 24, and one end of the socket contact 33 is a pin structure 34. The socket structure 24 and the pin structure 34 are connected and engaged.

[0027] The ends of the plug contact 23 and the socket contact 33 facing the flexible circuit board 1 are cylindrical structures 25. One end of the conductor 12 is welded to the flexible circuit board 1, and the other end of the conductor 12 is a sleeve structure 13. The cylindrical structure 25 is inserted into the sleeve structure 13 to form a plug-in fit.

[0028] An O-ring spring 14 is installed inside the sleeve structure 13, and the O-ring spring is used to fit around the outer periphery of the cylindrical structure 25. The end of the cylindrical structure 25 facing away from the insertion hole structure 24 is tapered.

[0029] The plug insulator 22 and the socket insulator 32 are provided with annular grooves surrounding the outer periphery of the cylindrical structure 25. When the cylindrical structure 25 and the conductor 12 are plugged in, the sleeve structure 13 is located in the annular groove.

[0030] In this embodiment, the plug housing 21 and the socket housing are machined from titanium alloy. The plug insulator 22 is designed with a high-voltage resistant structure. The plug contact 23 is fixed in the plug insulator 22 with epoxy adhesive, and then the plug insulator 22 and the plug housing 21 are bonded and fixed with epoxy adhesive. The socket insulator 32 is designed with a high-voltage resistant structure. The socket contact 33 is fixed in the socket insulator 32 to form an assembly with epoxy adhesive, and then the socket insulator 32 and the socket housing are bonded and fixed with epoxy adhesive.

The rubber pad 5 has an annular groove on the outer periphery of each socket structure 24, and the rubber ring 51 has an annular protrusion that fits into the annular groove. Both the annular groove and the annular protrusion are tapered. After the socket assembly 3 and the plug assembly 2 are locked by the locking nut and locking bolt 4, the rubber pad 5 is pressed against the rubber ring 51, so that the plug assembly 2 and the socket assembly 3 can form a sealed structure after docking, which improves the product's environmental resistance and electrical withstand capability under low air pressure conditions.
