13. electric connector as claimed in claim 8, it is characterised in that: the extension includes from the base portion forward fold Extend to form one first and to be formed one second is upwardly extended from first upper end, described second with it is corresponding The base portion be spaced apart, the elastic arm from second upper end upwards and relative to second plate face it is curved Folding extends to form.

14. electric connector as claimed in claim 8, it is characterised in that: the elastic arm includes from the upper end of the extension One second arm for being folded upward at one first arm extended to form and being extended to form straight up from the upper end of first arm, it is each The accepting hole is equipped with a recessing groove, and the recessing groove extends upward through the upper surface of the ontology and not downward through the ontology Lower surface, the conductor abuts the corresponding bearing surface, moves second arm along the left and right directions and enters pair The recessing groove answered.

15. electric connector as claimed in claim 8, it is characterised in that: the contact portion elastic arm is in a front and back Upwards closer to the base portion.

16. electric connector as claimed in claim 8, it is characterised in that: the accepting hole has an inner wall and the stop bit Block is spaced apart on the left and right directions, and the upper end of the inner wall has a guiding incline for guiding the conductor to underthrust Enter, the conductor between the bearing surface and the inner wall and abut the corresponding bearing surface and it is corresponding it is described in Wall surface.

17. the electric connector stated such as claim 8, it is characterised in that: each terminal also has the left and right from the base portion Two sides protrude out the fixed part to be formed respectively, and one fixing groove of recessed formation is distinguished in the left and right sides of each accepting hole, described Lower surface of the fixing groove downward through the ontology, each fixed part and the corresponding fixing groove interference engagement, and institute The plate face for stating contact portion is parallel to the plate face of the fixed part.

18. electric connector as claimed in claim 8, it is characterised in that: each terminal also has the left side from the base portion Right two sides protrude out the fixed part to be formed respectively, and the fixed part is fixed on the ontology, the extension and one of institute State the upper end tearing molding of fixed part.

19. electric connector as claimed in claim 8, it is characterised in that: each terminal also has from the upper of the base portion End upwardly extends the limiting section to be formed, and width of the limiting section on the left and right directions is greater than the base portion on the left side Width in right direction, each accepting hole are equipped with a limiting slot, and the limiting slot accommodates the corresponding limiting section, and institute The top that limiting slot is located at the limiting section with a confined planes is stated to move up to limit the corresponding limiting section.

20. electric connector as claimed in claim 19, it is characterised in that: the confined planes are equal with the bottom surface of the stop block Together.
