Description

Technical Field

[0001] The utility model belongs to the technical field of microcomputer protection devices, and particularly relates to a microcomputer face cover structure. 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] Currently, a microcomputer protection device consists of a housing, a face cover, a circuit board, a liquid crystal display screen, flexible buttons, indicator lights, and other electronic components. The installation structure of the indicator lights in most microcomputer protection devices is that the indicator lights use light-emitting diodes. The indicator lights are first welded to the circuit board through metal wires, then the circuit board is installed in the housing of the microcomputer protection device, and then the face cover is installed on the housing. The indicator lights are externally displayed through the lamp holes on the face cover. Such an installation structure has drawbacks. Since the indicator lights are welded and installed on the circuit board through metal wires, it is easy to cause the position of the indicator lights on the circuit board not to be aligned with the lamp holes on the face cover. Operators need to adjust the position of the indicator lights welded on the circuit board to align the indicator lights with the positions of the lamp holes on the face cover, which is troublesome to operate.

[0009] Further, the light-transmitting lamp cover includes:

[0010] A fixing part, on one end of which a connecting groove is opened. The fixing part is sleeved on the surface-mounted lamp bead through the connecting groove.

[0036] In this technical solution, the microcomputer protection device is composed of a housing 5, a face cover 1, a circuit board 2 and other electronic parts. The indicator light 3 is designed in the way of using a surface-mounted lamp bead 31 plus a light-transmitting lamp cover 32. First, the surface-mounted lamp bead 31 is pre-installed at a fixed position on the circuit board 2, then the circuit board 2 is positioned and installed in the housing 5, and then the light-transmitting lamp cover 32 is sleeved on each surface-mounted lamp bead 31, so that the position of the indicator light 3 on the circuit board 2 as a whole is not easily shifted. Finally, the face cover 1 is covered on the housing 5 and is fixedly connected by setting fasteners. A plurality of lamp holes 11 are provided on the face cover 1 in an aligned manner. When the face cover 1 is fixed on the housing 5, the lamp holes 11 are naturally aligned with the indicator lights 3.

[0037] With the above structure, it is possible to effectively avoid the offset of the indicator light 3 when it is installed on the circuit board 2, prevent the indicator light 3 from not being aligned with the lamp hole 11 on the face cover 1, making the installation and fixation between the indicator light 3 on the circuit board 2 and the face cover 1 more convenient and highly practical.
