Description

Technical Field

[0001] The utility model belongs to the technical field of microcomputer protection devices, and particularly relates to an anti-jamming structure for the keyboard of a microcomputer front cover. Background Art

[0002] A microcomputer protection device is a power system protection device based on microprocessor technology, mainly used for real-time monitoring of the operating state of the power system, quickly identifying faults (such as short circuits, overcurrents, ground faults, etc.), and isolating the fault area through logical judgment and execution of actions (such as tripping, alarming) to ensure the safe and stable operation of power equipment and systems.

[0003] Flexible keys connected to the internal circuit board are usually arranged on the front cover of the microcomputer protection device. By pressing the flexible keys, they are abutted against the control buttons installed on the circuit board to achieve the operation of the microcomputer protection device. In the prior art, most flexible keys on microcomputer protection devices are prone to getting stuck in the key holes of the front cover and unable to rebound during the pressing process, thus affecting subsequent use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-jamming structure for the keyboard of a microcomputer front cover to solve the above technical problems.

[0005] In view of this, the utility model provides an anti-jamming structure for the keyboard of a microcomputer front cover, including:

[0006] A front cover with a plurality of key holes opened thereon;

[0007] A keyboard including a plurality of flexible keys. Each flexible key includes a pressing part and an abutting part. The pressing part is correspondingly arranged in each key hole and can be pressed along the Y direction, and the abutting part is arranged on the pressing part;

[0008] A limiting baffle with a plurality of through holes opened thereon. Each abutting part passes through the through holes;

[0009] Wherein, when the pressing part is pressed along the Y direction, the abutting part abuts against the control button on the circuit board, and the pressing part abuts against the limiting baffle.

[0010] Further, the keyboard further includes a fixing plate with a plurality of connecting holes opened thereon;

[0011] Wherein, a plurality of pressing parts are correspondingly installed at each connecting hole, and the abutting parts pass through the connecting holes.

[0012] Further, the pressing part is integrally connected to the fixing plate.

[0013] Further, a plurality of positioning rods are further arranged on the front cover, and a plurality of first positioning holes are opened on the fixing plate;

[0014] Among them, a plurality of positioning rods and a plurality of first positioning holes are plug-fitted correspondingly.

[0015] Furthermore, a plurality of second positioning holes are provided on the limit baffle;

[0016] Among them, a plurality of positioning rods and a plurality of second positioning holes are plug-fitted correspondingly.

[0017] Furthermore, a positioning groove for adapting the control button is provided on the abutting portion.

[0018] Furthermore, a circular arc chamfer structure is provided on the pressing portion.

[0019] The beneficial effects of the utility model are:

[0020] When the operator operates the keyboard, the abutting part is driven to slide in the through hole by the abutting pressing part, and the abutting part contacts the control button on the circuit board, thereby realizing the control of the microcomputer protection device. When the pressing part moves along the Y direction in the key hole due to the abutment of the operator, the peripheral edge of the pressing part will abut against the limit baffle, thereby limiting the movement of the peripheral edge of the pressing part, avoiding the situation where the pressing part is stuck in the key hole and cannot rebound, preventing the use of the microcomputer protection device from being affected, and effectively improving the practicality.

[0028] Embodiment 1:

[0029] This embodiment provides a microcomputer cover keyboard anti-jamming structure, including:

[0030] A cover 1, on which a plurality of key holes 11 are provided;

[0031] A keyboard 2, the keyboard 2 includes a plurality of flexible keys 21, each flexible key 21 includes a pressing portion 211 and an abutting portion 212, the pressing portion 211 is correspondingly arranged in each key hole 11 and can be pressed along the Y direction, and the abutting portion 212 is arranged on the pressing portion 211;

[0032] A limiting baffle 3, on which a plurality of through holes 31 are provided, and each abutting portion 212 passes through the through hole 31;

[0033] Wherein, when the pressing portion 211 is pressed along the Y direction, the abutting portion 212 abuts against the control button 5 on the circuit board 4, and the pressing portion 211 abuts against the limiting baffle 3.

[0034] In this technical solution, the microcomputer protection device includes structures such as a housing 6, a cover 1, a keyboard 2, and a circuit board 4. The circuit board 4 is installed in the housing 6 and a control button 5 is installed on the circuit board 4. The cover 1 is installed on the housing 6 by setting fasteners. A storage cavity is provided on one side of the cover 1 close to the housing 6 along the Y direction, and the storage cavity can be used to install and place parts such as the keyboard 2 and the liquid crystal screen.

[0035] On the front cover 1, a plurality of key holes 11 are provided along the Y direction. A flexible button 21 is correspondingly arranged in each key hole 11. The flexible button 21 can be made of rubber material. The abutting portion 212 on each flexible button 21 is used to correspondingly abut against each control button 5 on the circuit board 4. A limiting baffle 3 is also installed in the storage cavity of the front cover 1. The limiting baffle 3 is located between the flexible button 21 and the control button 5, and the abutting portion 212 of the flexible button 21 passes through the through hole 31 of the limiting baffle 3. Through the adaptive connection between the abutting portion 212 and the through hole 31, it can play a certain positioning role in the installation of the flexible button 21 and enhance the installation stability of the flexible button 21.

[0036] When an operator operates the keyboard 2, by pressing the pressing portion 211, the abutting portion 212 is driven to slide in the through hole 31. The abutting portion 212 contacts the control button 5 on the circuit board 4, thereby realizing the control of the microcomputer protection device. When the pressing portion 211 moves along the Y direction in the key hole 11 under the contact of the operator, the periphery of the pressing portion 211 will abut against the limiting baffle 3, thereby restricting the movement of the periphery of the pressing portion 211 and avoiding the situation that the pressing portion 211 is stuck in the key hole 11 and cannot rebound, preventing the use of the microcomputer protection device from being affected, and effectively improving the practicability.

Through this structural design, the installation stability of the flexible keyboard 2 on the front cover 1 can be effectively enhanced.

[0042] Furthermore, the pressing portion 211 is integrally connected to the fixing plate 22. This enhances the connection firmness between the pressing portion 211 and the fixing portion, and at the same time can effectively prevent the pressing portion 211 from shifting and getting stuck when being contacted and squeezed, with high practicability.
