Description

Technical Field

[0001] This utility model relates to power supply devices, and more particularly to a miniature power supply box. Background Technology

[0002] For gift boxes and holiday clothing with flashing effects, a power box with built-in batteries and a switch button is typically used to control the light string. Existing power boxes generally connect two button batteries in series, with one end of the battery pack connected in series with a pin on the button. The other end of the battery pack and another pin on the button are then led out via wires. This connection method requires soldering between the battery pack and the button. Furthermore, the wires need to be properly routed within the power box to match the button pins, making assembly difficult and prone to issues like desoldering and disconnection. In addition, wiring and soldering operations sometimes need to be performed within the confined space of the box, increasing the assembly process complexity and reducing production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a miniature power supply box that is reasonably laid out, easy to assemble, and stable and reliable, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A miniature power supply box includes a housing and a bottom cover. A partition is formed inside the housing. A switch is provided on the top of the partition. Two battery holders are formed below the partition. Two pins of the switch pass through the partition and extend into the two battery holders respectively. The two pins of the switch are bent and attached to the bottom surface of the partition. Each of the two battery holders contains a button cell battery with opposite electrode directions. The two pins of the switch abut against the top surface of each button cell battery. Electrode plates abut against the bottom surface of each button cell battery. The bottom cover covers the bottom of the housing. Two elastic pads are provided on the bottom cover. The two elastic pads elastically abut against the two electrode plates respectively. The leads of the two electrode plates pass through the housing and extend outward.

[0006] Preferably, the top surface of the partition is formed with a square support, the switch is a tactile switch, and the switch is locked in the square support.

[0007] Preferably, the partition has four reinforcing ribs extending outward from the corners of the square support.

[0008] Preferably, a top cover is fixed to the top of the housing, and a keycap that can move up and down elastically is formed at the center of the top cover, and the keycap is aligned with the switch.

[0009] Preferably, a clearance groove is formed at the lower edge of the battery holder, and the welding portion of the electrode sheet passes through the clearance groove.

[0010] Preferably, a first buckle is formed on the inner side of the lower end of the housing, and two slots are provided at the lower end of the housing. The two slots are arranged opposite to the first buckle. The bottom cover includes two outwardly protruding tenons, which are respectively engaged in the two slots. One edge of the bottom cover is engaged in the inner side of the first buckle.

[0011] Preferably, a second buckle is formed on the inner side of the lower end of the housing, the second buckle is located between two slots, and the second buckle engages with the edge of the bottom cover.

[0012] Preferably, a threading hole is formed between the bottom of the slot and the tenon.

[0013] Preferably, the shell is a cylindrical shell.

[0014] Preferably, the upper edge of the housing has an outwardly extending outer edge.

[0015] In the miniature power supply box disclosed in this utility model, the switch and the button battery are respectively disposed on the upper and lower sides of the partition. After the two pins of the switch pass through the through hole in the partition, the two pins are bent laterally. This bending method can fix the switch and make good contact with the button battery. The button battery is installed in two battery holders with opposite installation directions, so that the switch is connected in series between the two button batteries. Then, two electrode plates are respectively placed against the bottom surface of the two button batteries. After the bottom cover is closed on the bottom of the housing, the electrode plates, the button batteries and the pins of the switch are reliably electrically connected under the elastic force of the two elastic pads. The leads of the two electrode plates pass through the housing and are connected to the light string. As can be seen from the above structure, this utility model connects the switch in series between two button batteries. The switch and the button batteries do not need to be connected through electrodes or leads, which not only facilitates assembly but also improves the reliability of electrical connection. At the same time, the leads of the electrode plate can pass through the housing and come out directly, eliminating the need for complex wiring design in the narrow space inside the housing, further simplifying the assembly process, and making the circuit structure more stable and reliable.

[0023] This utility model discloses a miniature power supply box, combined with Figures 1 to 6 As shown, it includes a housing 1 and a bottom cover 2. A partition 10 is formed inside the housing 1. A switch 11 is provided on the top of the partition 10. Two battery holders 12 are formed below the partition 10. Two pins of the switch 11 pass through the partition 10 and extend into the two battery holders 12 respectively. The two pins of the switch 11 are bent and attached to the bottom surface of the partition 10. The two battery holders 12 are respectively provided with button batteries 4. The electrodes of the two button batteries 4 are opposite in direction. The two pins of the switch 11 abut against the top surface of the two button batteries 4 respectively. The bottom surface of the two button batteries 4 abuts against electrode plates 5 respectively. The bottom cover 2 covers the bottom of the housing 1. Two elastic pads 21 are provided on the bottom cover 2. The two elastic pads 21 elastically abut against the two electrode plates 5 respectively. The leads of the two electrode plates 5 pass through the housing 1 and extend outward.

[0024] In the above structure, the switch 11 and the button battery 4 are respectively disposed on the upper and lower sides of the partition 10. After the two pins of the switch 11 pass through the through hole 101 on the partition 10, the two pins are bent laterally. This bending method can fix the switch 11 and make good contact with the button battery 4. The button battery 4 is installed in the two battery holders 12 with opposite installation directions, so that the switch 11 is connected in series between the two button batteries 4. Then, the two electrode plates 5 are respectively placed against the bottom surface of the two button batteries 4. After the bottom cover 2 is closed on the bottom of the housing 1, under the elastic force applied by the two elastic pads 21, the electrode plates 5, the button batteries 4 and the pins of the switch 11 are reliably electrically connected. The leads of the two electrode plates 5 pass through the housing 1 and are connected to the light string. As can be seen from the above structure, the present invention connects the switch 11 in series between two button batteries 4. The switch 11 and the button batteries 4 do not need to be connected through electrodes or leads, which facilitates assembly and improves the reliability of electrical connection. At the same time, the leads of the electrode plate 5 can pass through the housing 1 and come out directly, without the need for complex wiring design in the narrow space inside the housing 1, further simplifying the assembly process, and the circuit structure is more stable and reliable.
