Semi-finished capacitor structure

The utility model provides a semi-finished capacitor structure including a core bar provided with a core bar hole and a core body coiled on the core bar. The semi-finished capacitor structure also includes a first blocking rod and a second blocking rod. The first blocking rod is formed by connecting a first rod head with one end of a first rod body fixedly. The second blocking rod is formed by connecting a second rod head with one end of a second rod body fixedly. The other end of the first rod body and the other end of the second rod body are inserted into the core bar hole from two ends of the core bar hole. And the other end of the first rod body is connected with the other end of the second rod body is a dismountable manner in the core bar hole. The first rod head and the second rod head are covered outside the core bar hole and seal the core bar hole. By using the semi-finished capacitor structure provided by the utility model, metal spraying operation can be performed on two end faces of a capacitor at
