できる。As described above, in the wire pressure welding method and the pressure welding terminal structure of the pressure welding terminal according to the present invention, the pressure welding blade is provided with the opening portion for preventing the expansion of the pressure welding blade. The press-fitting engagement plate is integrally provided on at least one side wall portion of the press-connecting terminal in a bendable state. As a result, the press-fitting engagement plate pushes down the covered electric wire and the U of the press-contact blade is pressed.
When the press-fitting engagement plate is pressed into the slot and the press-fitting engagement plate is locked to the press-contact blade, the press-contact blade is corrected to a normal state and locked so as not to be displaced. Therefore, it is possible to reliably prevent deterioration of the contact force due to stress relaxation or the like over time, and to obtain high reliability for the pressure contact terminal.
Since the assembling can be automated and the number of processes and the number of parts can be reduced, workability can be improved and manufacturing cost can be reduced.
