Description

Technical Field

[0001] The utility model relates to a charged display. Background Art

[0002] The live display is used as a live indicator in the switch cabinet. It is an important indicator of whether the switch circuit is powered on or off, which is related to personal safety. Moreover, as a display device, it will run on the switch cabinet for a long time. This places very high requirements on the reliability of the display unit of the live display. According to working experience and related data, the failure rate of LED is much higher than that of other devices, because the LED usually has a lifespan of 5 years, and the design lifespan of a cabinet should be more than 10 years. Once it fails to display, it needs to be replaced. In order to improve efficiency and reduce maintenance costs, a live display solution with replaceable LEDs has emerged. This solution adopts independent modular design of the lamp bead circuit and directly replaces the display lamp. There is no need to open the switch cabinet, disassemble the entire machine and the circuit during the process, and it can be replaced under power without waiting for power outage maintenance.

[0003] However, the existing display modules adopt a single display lamp bead design and use a dual-core terminal, such as a DC terminal or an earphone jack. This will cause two problems:

[0004] (1) If a single display lamp is damaged, it is likely that the device has been used for a long time and the lamp life has been exhausted. If only the single unit that cannot display is replaced, the other two units are still in danger of being unusable at any time, which is easy to cause repeated maintenance. Because the cost of the lamp is much lower than the cost of maintenance, the best approach is to replace the entire set of display units.

[0005] (2) The size of a single lamp bead is small, and it is inconvenient to install it by hand. In addition, the replacement module is usually connected by headphones or a similar DC two-core plug. The metal part of the male and female sockets is in contact with a small area and is easily affected by oxidation. This may cause the terminal to oxidize and fail before the lamp bead is damaged.

[0006] In addition, utility model patent CN 209496565U discloses a miniaturized plug-in high-voltage live display, which uses screws and the front flange of the fixed shell to clamp the panel of the high-voltage switch cabinet. A screwdriver is required, which is inconvenient to install, so improvement is needed. Utility Model Content
