Description

Technical Field

[0001] This utility model relates to the field of battery fuse protection technology, and in particular to an insulation structure for UPS battery fuses. Background Technology

[0002] The battery mode of the UPS requires a battery box consisting of 32 lead-acid batteries (12V each) connected in series to power the UPS. The DC voltage between the positive and negative terminals of the battery box is as high as 384V or more. To prevent arcing and short-circuiting of the positive and negative connection wires inside the UPS, a fuse needs to be added inside the UPS to ensure that the power supply can be cut off by blowing the fuse in the event of a short circuit downstream of the fuse. However, the exposed metal terminals at the front end of the fuse still pose a risk of arcing and short circuit due to the lack of overcurrent protection from the fuse, requiring enhanced insulation.

[0003] Due to limited internal space in a UPS, it's impossible to enhance insulation by increasing the distance between the positive and negative metal terminals. Therefore, insulating adhesive is applied to the positive and negative metal terminals to strengthen insulation. However, this process causes production problems. The insulating adhesive needs to be applied manually, which is costly and requires a long time to dry completely before assembly, significantly impacting production efficiency and costs.

[0025] This invention addresses this issue by placing a first insulating paper 3 and a second insulating paper 4 on the upper and lower sides of the PCB board 1, respectively, to wrap around the fuse 2 and the front and rear metal connection terminals. This strengthens insulation and prevents arcing short circuits between the positive and negative terminals and arcing short circuits to surrounding circuits. This solution is easy to install, has low labor and material costs, and is more convenient for replacement and maintenance. Furthermore, the insulating paper can be selected or cut to size and length according to the fuse 2, resulting in a smaller and more suitable space for the insulating paper.

[0032] like Figure 4As shown, the outer shape of the first insulating paper 3 can be in the shape of "ji" or "gong". The first cardboard 30 is inserted into the first slot 10. An insulating space is formed by the first cardboard 30, the second cardboard 31 and the third cardboard 32 to provide insulating protection for the fuse 2 wrapped inside and the connecting terminals of the fuse 2, ensuring that there is no arcing short circuit between the positive and negative fuses 2, and also strengthening the insulation of the positive and negative fuses 2 to other circuits on the PCB board 1.
