Charging piles refer to charging devices that provide energy replenishment for electric vehicles. Their functions are similar to those of gas pumps in gas stations. They can be fixed on the ground or on the wall, installed in public buildings and residential parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels.

[0003] New energy vehicles are all equipped with charging bases that match the charging piles. When installing the charging base, the internal cables and circuit boards need to be connected, which involves the connection between the cable shielding layer and the ground wire interface. The existing connection method is to directly connect the cable and the circuit board by welding. However, due to the limited space inside the charging base and the certain strength of the cable, the operator cannot adjust the cable to a suitable bending state as required, which makes it difficult for the operator to operate. At the same time, after the cable and the circuit board are welded together, the cable is easily disconnected when subjected to external force, and the reliability and safety of the charging base are low.

[0009] In one embodiment of the present invention, the shape of the metal layer corresponds to the shape of the FPC flexible cable, including an arc-shaped plate-shaped base portion and an extension portion vertically connected to one side of the base portion.

[0010] In an embodiment of the present invention, the base portion is arranged on a raised surface of the main body portion, and the extension portion is arranged on the connecting portion along the length direction of the connecting portion.

[0011] In an embodiment of the present invention, the contact point is provided at one end of the extension portion away from the base portion.

[0012] In an embodiment of the present invention, the metal layer is made of copper foil.

[0013] In one embodiment of the present invention, a shielding ring is further included, and the shielding ring is sleeved on the outside of the shielding wire and presses the connection position between the shielding wire and the FPC flexible flat cable.

[0032] The FPC flexible flat cable 2 has a metal layer 3 on one side thereof, a contact 4 is provided at one end of the metal layer 3, and the end of the FPC flexible flat cable 2 provided with the contact 4 is plugged into the FPC cable socket 1, and the other end is connected to the shielding wire through the metal layer 3.

[0033] Instructions for use: Connect the FPC cable socket 1 to the circuit board A; process one end of the shielded wire B so that the shielding wire C inside the shielded wire B is exposed to a certain length (the shielded wire is a tubular structure as a whole, including an insulating skin and shielding wires C arranged in parallel and in a circular array inside the insulating skin), and then fit the main part 21 of the FPC soft flat cable 2 to the outside of the insulating skin of the shielded wire, and make the metal layer 3 on the FPC soft flat cable 2 face outward, and then bend the shielding wire backward (that is, toward the main part 21 of the FPC soft flat cable 2) so that the shielding wire covers the main part 21 on the outside of the main part 21 and contacts the metal layer 3 on the main part 21, and at the same time, make the connecting part 22 extend from the gap between the shielding wires; then put the shielding ring 5 on the shielding wire and move the shielding ring 5 to a position corresponding to the main part 21, so that the shielding ring 5 presses the shielding wire and the FPC soft flat cable 2, and finally plug the end of the FPC soft flat cable 2 provided with the contact 4 into the FPC cable socket 1, and the connection is completed.
