Shield Connector Crimp Structure to Suppress Barrel Springback

The patent applies preliminary anti-action by forming a depressed portion (counter-sunk hole) in advance at the crimping position on the first conductor. This pre-prepared recessed structure anticipates and counteracts the springback effect that will occur during crimping, allowing the extending piece to be excessively deformed into the depressed portion and then return to the correct position, preventing it from being lifted away from the surface.

The patent changes the geometric parameter of the first conductor by introducing a depressed portion with a specific shape and depth. This structural parameter change creates a recessed space that accommodates the excessive deformation of the extending piece during crimping, enabling the metal extending piece to be pushed into the depressed portion and then spring back to the proper crimping position.

The patent extracts and eliminates the complex locking claw and locking hole structures from the conductor design. Instead of adding these complicated mechanical interlocking features, the invention uses a simpler approach where the extending piece is crimped into a depressed portion, maintaining fixing strength while significantly reducing structural complexity.

Instead of creating protruding locking claws on the first conductor that engage with holes in the second conductor, the patent inverts the approach by creating a recessed depressed portion in the first conductor that receives the extending piece. This inversion simplifies the structure by eliminating the need for complex interlocking features while achieving the same fixing function.
