Abstract
Description
Technical Field
[0001] The utility model relates to a pre-assembled USB interface holiday light controller, belonging to the field of holiday light components. Background Art
[0002] The holiday light controller includes a housing, a circuit board, wires, a USB connector, and a control button. The circuit board is installed in the housing, and a wire is welded to one end of the circuit board, and a USB connector is welded to the other end of the wiring board. In actual production, the housing includes an upper shell and a lower shell, which are usually processed by a plastic manufacturer. The wiring board is then installed in the lower shell and delivered to another manufacturer separately from the upper shell for wiring. After the wiring is completed, the upper shell is buckled on, and the controller is assembled. However, the wiring board in the prior art is installed in the lower shell without a forced fixing structure. It only relies on the outer edge of the wiring board to be stuck in the groove of the lower shell. Since the wiring process is handed over to another manufacturer, the wiring board is easy to fall out of the groove during the delivery process, which causes trouble for the wiring manufacturer to connect the wires. Summary of the invention
[0003] The utility model aims to overcome the shortcomings of the prior art and provide a pre-assembled USB interface holiday light controller with a buckle, which can forcibly buckle a wiring board and prevent it from falling off, thereby facilitating delivery to the factory for wiring.
[0004] The technical solution of the pre-assembled USB interface holiday light controller of the utility model is: it includes a shell, a button is arranged on the shell, a terminal block is arranged in the shell, a USB connector is welded at one end of the terminal block, and an electric wire is welded at the other end of the terminal block, the shell includes an upper shell and a lower shell, and installation buckles are arranged on both sides of the inner wall of the lower shell.
[0005] The pre-assembled USB interface holiday light controller of the utility model is mainly characterized in that installation clips are respectively arranged on both sides of the inner wall of the lower shell body. With the installation clips, the terminal block can be installed in the lower shell body and fixed by the installation clips. The terminal block does not fall off, thus realizing pre-assembly, facilitating delivery to the manufacturer for assembly, and having good practicality.
[0006] The utility model discloses a pre-assembled USB interface holiday light controller, in which shelves are provided on both sides of one end of the lower shell, and a shelf is provided at the other end of the lower shell. The shelf and the shelf have the same horizontal height. The terminal block is placed on the shelf and the shelf, and is clamped by the mounting clip, so that the installation is more stable and reliable. The mounting clip can be in the shape of a block or a strip, and a slope is provided on the mounting clip. With the slope, it is convenient to install the terminal block under the mounting clip. There are 2-4 block-shaped mounting clips, and multiple mounting clips can fix the terminal block more securely. Fixing holes are provided in each of the four corners of the lower shell, and fixing columns are provided at the corresponding positions of the upper shell. The fixing columns cooperate with the fixing holes. During assembly, the fixing columns can be directly buckled into the fixing holes to buckle the upper shell and the lower shell, so that the assembly is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model relates to a pre-assembled USB interface holiday light controller, such as Figure 1 — Figure 4As shown, it includes a shell 1, a button 4 is arranged on the shell, a wiring board 2 is arranged in the shell, a USB connector 3 is welded at one end of the wiring board, and a wire 5 is welded at the other end of the wiring board. The shell includes an upper shell 6 and a lower shell 7, and mounting buckles 9 are arranged on both sides of the inner wall of the lower shell 7. The main feature of this scheme is that mounting buckles 9 are arranged on both sides of the inner wall of the lower shell 7. After the mounting buckles are arranged, the wiring board 2 can be installed in the lower shell 7 and fixed by the mounting buckles 9. The wiring board does not fall off, and pre-assembly is achieved, which is conducive to delivery to the manufacturer for assembly and has good practicality. A shelf 10 is arranged on each side of one end of the lower shell 7, and a shelf 11 is arranged at the other end of the lower shell 7. The shelf 11 has the same horizontal height as the shelf 10. The wiring board 2 is placed on the shelf 11 and the shelf 10, and is clamped by the mounting buckle 9, so that the installation is more stable and reliable. The mounting buckle 9 can be in the shape of a block or a strip, and a slope 12 is arranged on the mounting buckle 9. With the slope, it is convenient for the wiring board to be loaded under the mounting buckle. There are 2-4 block-shaped mounting buckles, and multiple mounting buckles can fix the wiring board more securely. The four corners of the lower shell 7 are respectively provided with fixing holes 15, and the corresponding parts of the upper shell 6 are respectively provided with fixing columns 16, and the fixing columns 16 are matched with the fixing holes 15. When assembling, the fixing columns can be directly buckled into the fixing holes to buckle the upper shell and the lower shell, which is convenient for assembly.
