Description

Technical Field

[0001] The utility model relates to a floating connection module, in particular to a cover assembled with a flexible circuit board, wherein corresponding positions between the cover and the insulating seat are provided with a limit and guide structure, and a plurality of conductive terminals are penetrated in the insulating seat. When the cover is vertically floated and displaced, the conductive terminals can maintain elastic contact with the flexible circuit board. Background Art

[0002] With the booming development and technological advancement of the audio-visual related industries and the popularity of home theaters, most households are equipped with audio, speakers, DVD players, televisions and other audio-visual playback equipment. Furthermore, in order to enable the electronic components in electronic related products to perform their proper functions, electrical connectors are generally used as a bridge for electrical signal transmission and communication between each other. Since the design of electrical connectors for signal transmission is usually specifically designed for the dual development of increasing high-speed signal transmission and miniaturization, electrical connectors of the flexible printed circuit (FPC) or flexible flat cable (FFC) type with an increased number of terminals and a reduced size, lighter weight, and more flexibility and thinness have emerged and are widely used in various electronic related products.

[0003] However, when a general flexible printed circuit (FPC) or flexible flat cable (FFC) type electrical connector is connected, a cover of a cover-down type or a rotary cover-down type is usually used to fix the flexible printed circuit (FPC) or flexible flat cable (FFC) and connect it to the electrical connector to form an electrical connection. However, since audio, speakers, DVD players, televisions and other audio and video playback devices generate audio vibrations when in use, the fixing cover may become loose or detached during long-term use or large-scale vibration or shaking. In addition, the flexible printed circuit that is positioned only by pushing or pressing down may also generate vibrations due to the vibration source, thereby causing the flexible printed circuit to be detached, offset or have poor contact when in electrical contact. Therefore, it is impossible to use a general fixing structure to form a stable electrical connection for electronic related products with a vibration source. Therefore, how to solve the above problems and deficiencies is the key to be studied and improved by those engaged in this industry or relevant technical personnel in this field.

The two side edges of the board body 121 can also be set as buckling grooves 24, and the two sides of the inner wall of the assembly space 210 of the cover 21 corresponding to the board body 121 can also be set as the design type of the buckling portion 123, so that a positioning structure to prevent separation is formed between the board body 121 and the assembly space 210.
