Computer keyboard capable of preventing disconnection by clamping pressure magnetic valve

Abstract

The invention discloses a computer keyboard capable of preventing disconnection by clamping a pressure magnetic valve. The keyboard structurally comprises a keyboard main board, function keys, an anti-falling connecting device, an indicator lamp, space keys and auxiliary keys. The function keys are embedded in the upper surface of the keyboard main board, the auxiliary keys are arranged below thefunction keys, and the space keys are arranged in the auxiliary keys and installed on the upper surface of the keyboard main board in an embedded mode. The connecting rod and the conducting wire are connected through the fixing abutting block and the tapping conducting ring, so that the connecting pin can be effectively prevented from shaking, and keyboard contact failure is prevented. The left metal strip and the right metal strip are subjected to repulsion of the electromagnet valve to realize expansion for clamping. The electromagnetic block attracts the metal sheet to further fix, so thatthe sensitivity of connecting the keyboard is improved. When the left metal strip and the right metal strip are pulled by the connecting pin to extrude the air bag to sense the air pressure value through the pressure measuring piece, the left metal strip and the right metal strip are restored to the original shape through the controller to be shrunk into concave arcs after exceeding the set air pressure value, the connecting pin and the outer shell are smoothly separated, and strong hard pulling is prevented.

Description

technical field [0001] The invention relates to the field of keyboards, more precisely, it relates to a computer keyboard that uses a pressure magnetic valve to lock and prevent disconnection. Background technique [0002] With the continuous improvement of living standards, the use of computers is becoming more and more extensive, and the pursuit of keyboards for input devices is higher. Keyboards can be divided into wireless and wired. Considering the control, most of them use wired keyboards and connect them through connecting lines. , the existing traditional technology is not considered comprehensively, and has the following disadvantages: [0003] When the connecting wire is pulled by heavy objects without knowing it, or when young and ignorant children pull the keyboard wire, since the connecting wire is directly connected to the keyboard, and its toughness is relatively limited, it is easy to make the inner core of the connecting wire touch Defective, causing the ke...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a computer keyboard that uses a pressure magnetic valve to lock and prevent disconnection, so as to solve the problems in the prior art when the connection line is pressed by a heavy object when it is unknowingly pulled, or When young and ignorant children pull the keyboard cable, since the cable is directly connected to the keyboard and its toughness is relatively limited, it is easy to make the inner core of the cable poor contact, resulting in keyboard failure or even the cable being torn off. Use, can only be used for repair or re-purchase, causing a waste of money and resources
