Flexible circuit board and terminal

Abstract

The invention belongs to the technical field of electronic equipment and particularly relates to a flexible circuit board and a terminal. The flexible circuit board comprises a body which comprises abearing area and a deformation area. A reinforcing plate is arranged on the back of the bearing area, and a buffer structure is arranged on an outer edge, connected with the deformation area, of the reinforcing plate. The terminal is suitable for the flexible circuit board, the terminal comprises a module shell, the module shell comprises elastic pressing plates, and the two symmetrical pressing plates are connected through a connecting plate. According to the invention, the buffer structure is arranged at an end part of the reinforcing plate such that breakage and damage of the flexible circuit board body at the edge of the reinforcing plate due to stress concentration are reduced, the working quality of the flexible circuit board is greatly improved, and the service life of the flexiblecircuit board is greatly prolonged; and meanwhile, two sides of the deformation area are pressed and fixed in a mounting area through the arranged module shell such that the assembling difficulty of the terminal is reduced, and the stability of the flexible circuit board terminal during working can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and specifically relates to a flexible circuit board and a terminal. Background technique [0002] The circuit board is an important part of the terminal equipment. The integrated setting of various components is realized through the circuit board to meet the small and light design requirements of the terminal equipment; and the flexible circuit board (FPC) is electrically connected because it can be bent. Field applications are becoming more and more extensive. In practical applications, some areas of the FPC need to be strengthened so that the area has a certain strength and can carry components. For example, the area where the FPC has a connector needs to be provided with a reinforcing board to carry the connector; for another example, the circuit board of the camera module needs to carry components such as photosensitive chips and lenses. Strong board. [0003] When the flexib...

Problems solved by technology

[0005] However, this solution still has the problem that the buffer member and the reinforcing plate are not firmly fixed, and the buffering effect is not good; in view of this, the present invention provides a flexible circuit board and a terminal. By setting a buffer structure at the end of the reinforcing plate, the effective Buffer the stress generated by the body bent at the end of the reinforcement board, reduce the crack and damage of the flexible circuit board body at the edge of the reinforcement board due to stress concentration, thus greatly improving the working quality and use of the flexible circuit board At the same time, the two sides of the deformation zone are pressed and fixed in the installation area through the set module shell, which not only reduces the difficulty of terminal assembly, but also effectively improves the stability of the flexible circuit board terminal when it is working.
