Module. [Prior Art] The keyboard is an indispensable input device for personal computers. Most of the early days, the keyboards of 84 and 101 buttons were used. At present, all of them are 104/105 keyboards that press the key. Each button on the keyboard is a small electronic switch. Within a second, the keyboard scan coded integrated circuit can check all buttons up to hundreds of times to detect that they are on or off. When the operator presses any button, the keyboard scan coded integrated circuit immediately generates a scan code and sends it to the central processing unit (CPU) of the host computer to inform when the button is pressed and when it is released. Since the button penetrates the top cover of the keyboard, there is a gap between the button and the button, and between the button® and the keyboard cover, so that liquid such as tea, beverage, and curry cannot be prevented from penetrating into the keyboard from the gap, once the inside of the keyboard is invaded by liquid. If it is light, it may cause malfunction or invalid action. In severe cases, it may cause a short circuit and damage the keyboard. In order to prevent liquid from intruding into the inside of the keyboard, many technical solutions have been pushed; for example, Taiwan Patent Publication Nos. 236428, 342983, 358571, 369191, 385891, 470190, 476429, 477446, 504026, 543864, 553433, and the like.

A kind of keyboard sealing module, which has a plurality of switches for implementing the keyboard sealing mold of the present invention, and - electrical far ^ '匕έ a thin film circuit board, with a key bracket, set in the thin film circuit a hard circuit board at the corner of the board j; one button press corresponding to the film circuit board = and has a plurality of button seats, one elastic member is mounted on the - button seat ^, a plurality of elastic members, each mounted on a button seat And by the elastic number of buttons, each button is a soft and transparent sealing sleeve, the package = 3 up and down movement; and a thin piece and the interface is immersed in the morning on the film circuit board, button holder, bomb Dust and other external/ΐ, the keyboard members are completely sealed to prevent the liquid and the cover and the human cap from having a cap corresponding to the rigid circuit board for receiving the rigid circuit board and providing one for each press; ^Over (four) sets of operating buttons to make the switch conduct, and the seal of the blood-electricity - two = an electrical connection to the hard circuit board through the electricity, the pipe and the electrical, see the contact surface with a sufficient seal. 6 M309158 In another embodiment, the 'key' module comprises a thin film circuit board having a plurality of (four) off, and a hard circuit board electrically connected to the corner; and a thin and soft sealing sleeve wrapped around the thin film circuit board Outside, the membrane circuit board is completely sealed 'and the sealing sleeve provides a conduit for an electrical connection to the rigid circuit _ (4), which has a sufficient seal between the conduit and the solder. In another embodiment, the conduit is provided by a tube member shaped like a PA port, which is made of a material that is compatible with the sealing sleeve and is fused to the sealing sleeve. The technical content and other objects and features of the present invention can be fully understood by referring to the following description of the embodiments of the drawings. [Embodiment] In the first figure, the appearance of a waterproof keyboard module 1 显示 is shown, the second diagram shows its internal configuration, and the third diagram shows its component exploded state, which can be used to explain the technical content of the creation. The keyboard sealing module 10 includes a thin film circuit board 20, which is an upper first circuit film 21, a lower second circuit film 22, and a first and second circuit film 21 and 22. A three-layer thin film circuit board composed of an insulating film 23; wherein the first circuit film 21 is provided with a line 24 and a contact 25, and the second circuit film 22 has a line 26 corresponding to the first circuit film 21 Point 27, each of the two upper and lower corresponding contacts 25 and 27 constitutes a switch. The insulating film 23 is disposed between the first and second circuit films 21 and 22, and is provided with a hole 28 at a position corresponding to each of the contacts 25 and 27 to make the first and second circuit films 21 and 22 The contacts 25 and 27 are electrically connected when the operation button 50 is in contact. The corner of the thin film circuit board 20 is electrically connected to a rigid circuit board 29, which is connected to a host computer (not shown) via an electronic mirror 70. The keyboard scan coded integrated circuit and the necessary electrical components are disposed on the rigid circuit board 29. The keyboard sealing module 10 further includes a button holder 30 disposed above the film circuit board 20 and having a plurality of button holders 31, each button holder 31 corresponding to a switch of the film circuit board 20 to support the movement of the button 50. The keyboard sealing module 10 further includes a plurality of elastic members 40, which are made of a resilient material, such as a bowl made of natural or synthetic rubber. Each elastic member 104 is mounted under a button holder 31 and faces the film. A switch on the circuit board 2〇. In the embodiment of the drawings, the elastic members 40 are individually formed, but all of the elastic members 40 may be integrally formed on an elastic lining (not shown), which is more flexible in individual assembly efficiency. The piece is high, but the overall material cost is more expensive than the individual molded elastic parts. Each of the buttons 50 is mounted on a button holder 31 and supported by the elastic member 40 to support the button holder 31 to move up and down, and the elastic restoring force of the elastic member 4 is often maintained on the film circuit board 20. The switch is in the position of 0 ff, and can be automatically returned to the original position by the elastic force of the elastic member 4 在 when the button 50 is depressed and then released. The above-mentioned thin film circuit board 20, key holder 30, elastic member 4, and push button 50 are conventional keyboard members, and therefore, only the above description will be briefly described. The present invention mainly consists in having a sealing sleeve 60 for sealing the above-mentioned keyboard member, which is made of a thin and soft transparent material, such as a thermoplastic polyurethane (TPU) film, which is placed one above the button 50. The cover 61 is formed, and a cover bottom 62 is formed under the circuit board 20 of the film M309158, and the periphery is welded together by ultrasonic waves (high frequency), and the film circuit board 2〇, the button holder 3〇, and the elastic member 40 are pressed. And the button 50 is in the morning, thus forming a completely sealed keyboard module 10, and the cover 61 of the 忒岔 cover 6 具有 has a cap 65 corresponding to the rigid circuit board 29, and a key cover 63 of each button 5 〇 It is used to receive the rigid circuit board 29 and each button 5 〇 so as to operate through the transparent cover cover 61 of the sealing sleeve: the key 50 turns on the switch. The sleeve bottom may not necessarily be transparent, or may be made of a different material than the sleeve cover 61. If the two are made of different materials, they should have the characteristics of being welded to each other. Since the electric winding 70 has to be electrically connected to the hard circuit board 29 through the cover 6 of the sealing sleeve 6 , the cover 61 has a pipe on the side of the cap 65 for receiving the rigid circuit board 29 for (10) 7q passes through to electrically connect the rigid circuit board 29'. The pipe is made of a bell-like tubular member 64, and the (4) sleeve 6G is made of a material that can be refining, and is ultrasonically welded to the sleeve. On the cover 61, the tube member is welded to the contact surface of the (4) 7q to provide a sufficient seal to prevent liquid from penetrating between the contact faces of the two. The third figure shows the internal shape of a keyboard 80 having a sealed module. In the figure, the symbol 81 is the upper cover of the keyboard, and the 82 is the lower cover of the keyboard. The sealing module 10 is placed on the training together with screws (not shown). Between the bottom and the bottom of the cover. The keyboard 8Q thus formed can be taken out and cleaned by simply screwing down the screw. There are other variations that can be made in this book. The fourth figure shows a simple shape of the keyboard sealing module 1_section shape, and the fifth figure shows the internal shape of a keyboard 80a having the dense 9 M309158 sealing module 10a.
