The implementation principle of the embodiment 2 of the application is as follows: the bottom scraps 51 and the side scraps 52 are formed at both ends of the G terminal 1 and the S terminal 2 by a punching method, so that both ends of the G terminal 1 and the S terminal 2 are protected during subsequent processes and transportation. The processing cost is effectively controlled in the electroplating link by a plating selection mode. The cooperation of the connecting groove 41 and the connecting column 42 ensures the connection stability of the plastic part 3 and the G terminal 1 and the uniformity of the medium around the S terminal 2, and the production cost of the ferrule structure is greatly reduced without additionally adding a string structure. The G terminal 1 and the rim charge 5 and the S terminal 2 and the rim charge 5 are separated in a cutting mode, so that the condition that metal wires appear at the ends of the G terminal 1 and the S terminal 2 is avoided as much as possible, and the product quality of the insert core structure is improved.
Through the mode, the product quality of the core insert structure can be improved under the condition of reducing the production cost of the core insert structure, and mass production and manufacturing of the core insert structure are facilitated.
Example 3:
referring to fig. 8, the difference between the present embodiment and embodiment 2 is that the number of the protection pins 6 on the material strip with the ferrule structure at each section is one, the adjacent protection pins 6 are respectively located at two sides of the ferrule structure, and the protection area 61 is formed by enclosing the protection pins 6 on the two adjacent material strips with the ferrule structure at each section.
Example 4:
referring to fig. 9, the difference between the application embodiment and the application embodiment 2 is that the number of the protection pins 6 on the material tape with the ferrule structure at each section is two, and the protection pins 6 on the same material tape are respectively located at two sides of the ferrule structure. The protection area 61 is formed by enclosing the protection pins 6 on two adjacent material strips with the core-inserting structure, namely, four protection pins 6.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
