Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of punching devices, and particularly relates to a strip punching jig. Background Art
[0002] PIN pins are installed in some products that need to be connected by electrical signals. Generally, there are multiple PIN pins.
