Structure for preventing reverse insertion of FPC golden finger

Abstract

A structure for preventing reverse insertion of an FPC golden finger comprises an FPC which is provided with a component area, an EMI film area and a golden finger area. A bending area is arranged between the golden finger area and the EMI film area, and an identification film is arranged on the bending area; and colors are printed on the identification film in a silk-screen manner and are used for marking whether the golden fingers of the FPC are in lower contact or upper contact. According to the structure for preventing the golden finger of the FPC from being reversely inserted, the bending area is arranged between the golden finger area and the EMI film area of the FPC, and the identification film is arranged on the bending area, so that a worker can conveniently distinguish whether the golden finger on the FPC is in upper contact or lower contact, and therefore, on the basis of not occupying too much space of the FPC, the false insertion of the golden finger can be prevented, and the false insertion of the golden finger can be prevented. The problems caused by misplug of the FPC golden finger can be prevented with the lowest cost.

Description

Technical Field

[0001] The utility model relates to the technical field of FPC, in particular to a structure for preventing the wrong insertion of FPC gold fingers. Background Art

[0002] AMOLED screens have the characteristics of bright display effect, high contrast, and small screen size, and are widely used in smart watch projects. The functions of smart watches are becoming more and more comprehensive, integrating a series of functions such as touch control, display, and NFC payment. Although many functional components have been added to smart watches, the volume requirements for smart watches are getting smaller and smaller. Especially for the FPC of smart watches, it is required that the size of the FPC is very precise and small, and the space on the FPC is limited, resulting in no relevant text and digital descriptions being added to the FPC. Therefore, there is too little information on the FPC, which brings some inconveniences in production. For example, for the FPC of the smart watch ZIF plug-in solution, since the operator is not clear whether the gold finger of the FPC is in the upper contact or the lower contact, the situation of burning out the AMOLED screen often occurs.
