Electric energy metering junction boxes are widely used in power systems. In order to adapt to various application scenarios, their specifications and models are very complicated, and they are divided into single-channel junction boxes, three-channel junction boxes and multi-channel junction boxes. The boxes of conventional junction boxes are all of an integral structure. In order to produce electric energy metering junction boxes of different specifications, different boxes need to be produced. Since the boxes are mostly made of insulating materials such as plastic or bakelite, their production mainly relies on mold forming.
