Wherein, the assembly welding feet are not integrally formed with the lower shell 2, and finally, the plug 20 is assembled.
S2, stamping and electroplating the contact sheet, injection molding the contact sheet and the main body 31 into a whole, assembling the dome sheet 32, and attaching the high-temperature adhesive tape 33.
S3, the upper shell 1 and the lower shell 2 are clamped and mounted together.
S4, the lower shell 2 is overturned, waterproof glue 17 is smeared at the gap, and finally the mounting plate assembly 11 is mounted in the lower shell 2.
By adopting the technical scheme, when the IC card connector is required to be manufactured, the upper shell 1 is punched and molded, the lower shell 2, the terminals 5 and the tact switch 3 are integrally molded through the injection mold, so that the slot 6 formed by the upper shell 1 and the lower shell 2 can be matched with an IC card to be inserted, then the main body 31, the contact sheet and the dome sheet 32 are mounted together to form the tact switch 3, and finally the mounting plate assembly is mounted, so that the tact switch 3 and the lower shell 2 are integrated, thereby realizing water resistance.
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.
