Battery box assembly with low impedance output

Abstract

The invention discloses a battery box assembly with low impedance output. The battery box assembly comprises a base, a cover cap, a positive electrode terminal, a negative electrode terminal and a spring, wherein the negative electrode terminal is mounted in a manner of being clung to the inner side of the base; the positive electrode terminal is mounted in a manner of being clung to the inner side of the cover cap; one end of the spring is connected with the negative electrode terminal and the other end of the spring is connected with a battery negative electrode arranged in the base; the positive electrode terminal is connected with a battery positive electrode; after the cover cap is arranged in the base, the cover cap is rotated; then the cover cap is locked through the matching of ananti-backing block arranged on the base and an anti-backing clamping block arranged on the cover cap. According to the battery box assembly provided by the invention, all components are in tight contact with one another, so that the impedance value output by a product is very stable; meanwhile, the anti-vibration performance also can be improved.

Description

technical field [0001] The invention relates to smart meters and various measuring instruments that need batteries, in particular to a low-impedance output battery box assembly. Background technique [0002] There are many ways to assemble batteries, of which there are two most commonly used ones: one is to design the positive and negative poles of the battery as pins, and then solder the two pins directly to the PCB board; the other is the traditional The positive and negative poles are both designed as shrapnel, and then the battery is directly snapped into the plastic shell. All there is bigger inconvenience and hidden danger of quality in these two kinds of modes. In the first way, it is very troublesome to replace the battery when the battery power is exhausted. It is necessary to disassemble the whole machine, and then remove the welded battery by a professional, and then install a new battery into the PCB board and then pass the welding equipment. Or manual welding....

These two ways all have bigger inconvenience and hidden danger of quality

In the first way, it is very troublesome to replace the battery when the battery power is exhausted. It is necessary to disassemble the whole machine, and then remove the welded battery by a professional, and then install a new battery into the PCB board and then pass the welding equipment. Or manual welding. This method is too expensive to replace. The other method is more convenient than the first one, but its function is limited and it is difficult to adapt to outdoor products. It cannot meet the working requirements of waterproof and vibration environments.
