Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit mainboards, in particular to an embedded flexible circuit mainboard with stable connection. Background Art

[0002] Flexible circuit board, also known as "soft board", is a printed circuit board made of flexible insulating materials such as polyimide or polyester film as the substrate. It has many advantages that rigid printed circuit boards do not have, such as light weight, thin thickness, good flexibility, etc. It is flexible and convenient to arrange, can be bent at will to adapt to the assembly requirements of various shapes, and can withstand repeated dynamic bending during use. Therefore, it is widely used in electronics, communications and other fields.

[0003] Although the existing flexible circuit motherboard technology has the characteristics of strong plasticity, the existing flexible circuit boards are mostly fixedly installed inside the machine during the installation process. Although they can be bent to a certain extent, the ends of the flexible circuit boards are easy to fall off during use, and the connection with the components is not tight and stable enough, so that it is relatively easy to have unstable connection problems during use.

[0004] Therefore, those skilled in the art provide an embedded flexible circuit mainboard with stable connection to solve the problems raised in the above background technology. Utility Model Content

[0012] As a further solution of the utility model: storage grooves are provided on both the left and right sides of the connecting plate, and the moving rod is movably connected to the inner cavity of the storage groove.

[0013] As a further solution of the utility model: a protective sleeve is movably connected to the surface of the electrical interface, and limiting blocks are fixedly connected to the four sides of the inner cavity of the protective sleeve.

[0014] As a further solution of the utility model: the upper and lower sides of the protective sleeve are fixedly connected with moving blocks, and the inner sides of the moving blocks are provided with anti-slip grooves.

[0015] The beneficial effects of the utility model are:
