The conducting terminal 40 is molded to form the insulator foot 10 through in-mould injection, and the upside of the insulator foot 10 is formed with receiving
Position the locating slot 12 of the retaining piece 20.Then, the retaining piece 20 is assemblied in the locating slot 12, and carried out again
Injection molding is operated, and forms the fixing retaining piece 30 in interior insulation cover plate 30.The retaining piece 20, the correspondence of insulation cover plate 30
Terminal groove 21,31 is similarly formed at the position of the terminal groove 11.Four edges extension of the retaining piece 20 is formed with
Leg 22 is to strengthen the fixing power between the electric connector and printed circuit board (PCB).
The conducting terminal 40 includes base portion 41, from the tightening part 43 of the rear end inverse bending formation of the base portion 41, from institute
State tightening part 43 and tilt upward the extension 44 of extension formation, the contact site 45 for being formed at the end of extension 44, described in
The ends bent of contact site 45 extends the abutting part 46 formed towards the base portion 41 and the confession institute formed that is recessed from the base portion 41
State abutting part 46 and abut the depressed part 42 slided.
The outer rim of base portion 41 of the conducting terminal 40 is shaped in the insulator foot 10, and the tightening part 43 is laterally
Both sides be additionally provided with the side 47 that takes shape in the insulator foot 10 so that the conducting terminal 40 and the insulator foot 10 it
