When the fingerprint recognition assembly 130 is applied to the keyboard 100, the first flexible circuit board 1331 serves as the PIN of the keyboard body 110, the second flexible circuit board 1332 serves as the PIN of the backlight module 120, and the third flexible circuit board 1333 serves as the PIN of the fingerprint recognition module 131, so that the PIN of the keyboard body 110, the PIN of the backlight module 120 and the PIN of the fingerprint recognition module 131 are fused into one PIN of the flexible circuit board assembly 133. The sixth flexible circuit Board 1336 is used as the PIN of the flexible circuit Board assembly 133, and the Board-to-Board connector 1337 is arranged on the sixth flexible circuit Board 1336 so as to be connected with the Connect on the PCBA of the notebook computer in a Board-to-Board mode, so that the backlight PIN, the functional PIN and the fingerprint identification module 131PIN of the keyboard 100 are integrated, and when the keyboard is assembled to the Connect of the PCBA of the notebook computer, the three PINs can be assembled by the two previous work stations, and the PIN can be assembled once by one work station, thereby reducing the assembly times; furthermore, the PIN outlet end is connected outside in a Board-to-Board mode (namely, a Board-to-Board connection mode), and compared with the conventional flexible wire PIN port, the automatic connection can be realized, and the labor cost is reduced.
In addition, one end of the second flexible circuit board 1332, which is far from the fourth flexible circuit board 1334, is connected with the connection terminal of the backlight module 120 by soldering or ACF. Thus, one end of the flexible circuit board assembly 133 is connected to the connection terminal of the backlight module 120 by soldering or ACF (ACF is not a conventional soldering method generally seen in the prior art, and ACF is made of a special conductive material, is non-conductive at normal temperature, and can be electrically conductive when the ACF film is pressurized and heated), so that the connection method is simple.
The electronic device according to the embodiment of the present invention includes a motherboard and a keyboard 100, where the keyboard 100 is the keyboard 100, and the flexible circuit board assembly 133 is connected to the motherboard through the board-to-board connector 1337, and besides, the motherboard may have various structures that may occur in the present or future, which does not limit the scope of the present invention. Since the above-mentioned keyboard 100 has the above-mentioned advantages, the electronic device including the above-mentioned keyboard 100 also necessarily has the above-mentioned advantages.
In the description of the present invention, it should be understood that the azimuth or positional relationship indicated by the azimuth words "front", "back", are generally based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of describing the present invention and simplifying the description, and these azimuth words do not indicate or imply that the device or element to be referred to must have a specific azimuth or be constructed and operated in a specific azimuth, without limiting the scope of protection of the present invention; the orientation terms "inner" and "outer" refer to the inner and outer relative to the outline of the components themselves.
Spatially relative terms, such as "above … …," "above … …," "on top of … …," "above," and the like, may be used herein for ease of description to describe one or more components or features' spatial positional relationships to other components or features as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass not only the orientation of the elements in the figures but also different orientations in use or operation. For example, if the element in the figures is turned over entirely, elements "over" or "on" other elements or features would then be included in cases where the element is "under" or "beneath" the other elements or features. Thus, the exemplary term "above … …" may include both orientations "above … …" and "below … …". Moreover, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and all such cases are intended to be encompassed herein.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the present application. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, components, assemblies, and/or combinations thereof.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein.
The present invention has been illustrated by the above-described embodiments, but it should be understood that the above-described embodiments are for purposes of illustration and description only and are not intended to limit the invention to the embodiments described. In addition, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many variations and modifications are possible in light of the teachings of the invention, which variations and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
