Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to FIGS. 1-6, the present invention provides

The FPC board comprises a substrate 1 and an FPC board 2, wherein a plurality of one-way clamping portions 3 are arranged on the substrate 1, a plurality of connecting plates 4 which can be matched with the one-way clamping portions 3 for installation are arranged on the FPC board 2, connecting holes 5 and welding sleeves 6 are respectively arranged on the connecting plates 4, welding portions 7 which can be matched with one corresponding welding sleeve 6 are arranged on one side of each one-way clamping portion 3, and an opening 8 is formed in the upper surface of each welding sleeve 6;

the structure principle is as follows:

the connecting plates 4 on the FPC board 2 are independently aligned with the corresponding welding parts 7, and the one-way clamping parts 3 are inserted into the corresponding connecting holes 5 for one-way fixation, so that the FPC board 2 is prevented from being separated from the FPC board 2 or moving relative to the substrate 1 in the welding process, and the stability of the welding process is improved;

during welding, the opening 8 is welded, so that the welding sleeve 6 and the welding part 7 at the opening 8 are welded and connected.

The one-way clamping part 3 comprises a connecting cylinder 301, a conical clamping part 302 is arranged at the upper end of the connecting cylinder 301, and a hollow part 100 is arranged between the connecting cylinder 301 and the conical clamping part 302;

hollow portion 100 makes connecting cylinder 301 divide into two elastic rod 200 two when connecting hole 5 is installed elastic rod 200 draws close each other, realizes contracting, works as connecting hole 5 crosses behind the toper card portion 302 of establishing, toper card portion 302 of establishing will block and establish connecting hole 5 prevents that connecting hole 5 from breaking away from the toper card portion 302 of establishing realizes the purpose of one-way fixed.

The hollow part 100 of the present invention divides the connection cylinder 301 into two elastic rods 200.

The diameter of the connecting hole 5 is smaller than that of the conical clamping part 302.
