Abstract

Disclosed are a design method for an asymmetric edge-cutting die of a seamless shell of a connector, the die and an asymmetric edge-cutting method. The die comprises a driving mechanism, a shuttle-shaped piece and a sliding piece; the driving mechanism comprises two driving pieces arranged oppositely, the opposite surfaces of the two driving pieces are curved surfaces, and the curved surfaces aredesigned into the mode that when the two driving pieces move towards the same direction, the curved surfaces drive the shuttle-shaped piece located between the two driving pieces to make reciprocatingmotion once; an inclined groove is formed in the shuttle-shaped piece; and one end of the sliding piece is arranged in the inclined groove and makes reciprocating motion in the direction perpendicular to the moving direction of the shuttle-shaped piece along with the reciprocating motion of the shuttle-shaped piece, the other end of the sliding piece drives an asymmetric movable die core to makereciprocating motion by a predetermined distance relative to a fixed die core, and the purpose that the two edges of the seamless shell are subjected to asymmetric die-cutting through one die is achieved.

Description

technical field [0001] The invention relates to a design method of an asymmetric trimming mold for a seamless shell of a connector, a mold and an asymmetric trimming method. Background technique [0002] Connectors, such as USB connectors, have a metal shell with insulating colloid and several terminals inside the metal shell. On the one hand, the metal shell is used to fix the insulating colloid and several terminals, and on the other hand, it is a grounding terminal. The existing metal casings are divided into two categories: seamed metal casings and seamless metal casings. The seamless metal casings are gradually replacing the seamed metal casings and become the mainstream products in the industry. One end of the metal shell is a plug-in terminal, and the other end is a terminal. Generally speaking, for the convenience of wiring, most of the two sides of the terminal are die-cut into a symmetrical structure. However, the metal shell of some connectors needs to be designe...
