It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] An embodiment of the present utility model discloses an adapter for connecting a keyboard case and a tablet computer. As Figures 1-5 shown, it includes an adapter base 1 and an adapter cover 2. A bendable adapter circuit board 3 is installed between the adapter base 1 and the adapter cover 2. One end of the adapter circuit board 3 is electrically connected to a plug 4. The plug 4 passes through the adapter base 1 and is inserted into the interface of the tablet computer. Several contact plates 5 are installed at the other end of the adapter circuit board 3. The contact plates 5 are used for electrical connection with the keyboard case. The adapter base 1 and the adapter circuit board 3 are tightly connected by screws 6. The adapter base 1 is provided with positioning posts 11, and the adapter circuit board 3 is provided with positioning holes 31 that are in positioning cooperation with the positioning posts 11. In this embodiment, the number of contact plates 5 is set to five.

[0027] It should be noted that the plug 4 of the adapter is inserted into the interface of the tablet computer, and the contact plate 5 is electrically connected to the keyboard case, thereby providing an adapter that can quickly connect the keyboard case and the tablet computer. By using different types of plugs 4 to adapt to the tablet computer, the adaptability of the keyboard case is improved, meeting the various actual needs of users.

[0028] As Figure 4 and Figure 5 shown, the number of positioning posts 11 and positioning holes 31 is four each. It should be noted that the number of positioning posts 11 and positioning holes 31 being four each can quickly position the four sides of the adapter circuit board 3, facilitating installation. The side of the adapter circuit board 3 that contacts the adapter base 1 is provided with 3M glue, so that the adapter circuit board 3 is more firmly bonded inside the adapter base 1.

[0029] As Figure 4 and Figure 5 shown, the positioning posts 11 and the adapter base 1 are of an integrally formed structure.

[0030] As Figures 1-5 shown, the adapter cover 2 is provided with a through hole 21 corresponding to the contact plate 5, and the contact plate 5 is fixedly welded to the adapter circuit board 3. It should be noted that through the setting of the through hole 21, it is convenient to accommodate the contact plate 5.

[0031] As Figure 4 and Figure 5 shown, the contact plate 5 is provided with welding posts 51, and the adapter circuit board 3 is provided with welding holes 32 corresponding to the welding posts 51. It should be noted that the number of welding posts 51 and welding holes 32 is both set to two. Through the setting of the welding posts 51 and welding holes 32, it is convenient to weld and fix the adapter circuit board 3 and the contact plate 5.

[0032] As Figures 1-5 shown, the contact end face of the contact plate 5 is located inside the through hole 21.

[0033] As Figures 1-5 shown, the adapter circuit board 3 is an FPC board. It should be noted that since the adapter circuit board 3 is an FPC board, the adapter circuit board 3 is convenient for bending installation.

[0034] As Figures 3-5 shown, the plug 4 and the adapter circuit board 3 are connected through an adapter plate 7. The screw 6 passes through the adapter plate 7 and the adapter circuit board 3 in sequence and is threadedly fastened to the adapter base 1. In the specific implementation process, the screw 6 is threadedly connected to the adapter base 1. Since the adapter circuit board 3 is elastic, through the setting of the adapter plate 7, the strength of the adapter circuit board 3 is enhanced, and it is also convenient to install the plug 4.

[0035] Working principle: The plug 4 of the adapter is inserted into the interface of the tablet computer, and the contact plate 5 is electrically connected to the keyboard case, thereby providing an adapter that can quickly connect the keyboard case and the tablet computer. By adapting different types of plugs 4 to the tablet computer, the adaptability of the keyboard case is improved, meeting various actual needs of users.

[0036] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
