The existing ultrasonic welding process is influenced by welding process parameters, tool fixtures and equipment precision, excessive welding flux is easy to generate flash during welding wire design, so that assembly of a contact element is influenced, an unfirm attaching area can be generated when the welding flux is too little, and consistency among batches is difficult to guarantee.

II, low production efficiency;

the existing viscose glue process has long glue solution curing period, and the ultrasonic welding process needs a large amount of equipment debugging time before each batch of operation, so that the production period is long and the production efficiency is low.

III, the detection difficulty is high;

the existing adhesive or ultrasonic welding technology cannot detect the bonding condition of the bonding surface of the insulator and the insulating pressing plate after the operation is finished, cannot identify unqualified products, and has risks in subsequent use.

IV, when the contact piece is used in the prior art, the final stress surface is on a joint surface vertical to the insertion direction of the contact piece, and the risk of disengagement of the insulating pressing plate is high;

no matter the existing structure is glue or ultrasonic welding, when a connector product is inserted and combined with other plugs and the like, the contact piece can receive axial force, so that the stressed surface of the connector product during insertion is the combined surface of an insulating pressing plate and an insulator, the combined surface is slightly flawed during glue or ultrasonic welding, uneven stress can be caused, the insulating pressing plate and the insulator can be separated, and the product fails.
