Description

Technical Field

[0001] The utility model relates to the technical field of luminous handicrafts, and in particular to a switch box, a switch box assembly and a sign with an LED. Background Art

[0002] In some luminous crafts, light-emitting components are often embedded inside the crafts, and the LEDs of the light-emitting components are embedded in various positions of the crafts to achieve various lighting effects on the crafts. For example, in NBA or other sports events, each team and its fans will wear signs with luminous functions. The signs can achieve strobe, marquee and other luminous effects through the internal light-emitting components, thereby having a better aesthetic effect or being more ornamental. However, since the light-emitting components are embedded in the sign, only a window for replacing the battery is reserved. When the light-emitting components fail, the circuit board or chip in the light-emitting components cannot be repaired or replaced because the locking part is located inside the sign and away from the window, resulting in difficult maintenance for users. In addition, the existing light-emitting components are generally directly attached to the sign through a switch box. When subjected to large vibrations or pulling, they are easy to fall off, resulting in problems such as poor contact of the light-emitting components. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a switch box to solve the problem that the existing sign light-emitting components are difficult to maintain and easy to loosen.

[0004] The utility model adopts the following solution: the application provides a switch box, including an upper shell and a lower shell, with an installation space formed between the upper shell and the lower shell, the upper shell including a fixing portion and a flipping portion suitable for connecting with the lower shell, and at least one fastener is provided on each of the fixing portion and the flipping portion, and the fastener is suitable for being inserted from the upper shell toward the lower shell so that the locking direction and the loosening direction of the fixing portion and the flipping portion on the fastener are the same.

[0005] Furthermore, an elastic snap-fit ​​portion adapted to cooperate with the lower shell is formed on one end of the flip portion away from the fixing portion.

[0006] Furthermore, the flip portion and the fixed portion are connected via a flexible portion, and a through groove is provided on the flexible portion.

[0007] Furthermore, a fixing plate is formed by extending outward from the side of the lower shell.

[0008] Furthermore, two opposite side edges of the lower shell extend outward to form the fixing plate.

[0009] Furthermore, two fasteners are provided on each of the fixing portion and the flipping portion.

[0010] Furthermore, a plurality of supporting columns are formed on a side of the fixing portion facing the lower shell to tightly support the circuit board disposed on the lower shell.
