Furthermore, a lance portion 8 is provided on the surface portion 4b of the terminal insertion hole portion 4.

[0011] Reference numeral 9 denotes a locking member, and this locking member 9 has a rod shape with a square cross section as shown in FIG. A member main body 10 is provided, and a predetermined interval is provided on the lower surface of the member main body 10. A plurality of notches 11 are formed at the tip of the member body 10 and the notches 11. The end surface is formed into an inclined surface 11a, and the lower surface portion following this inclined surface 11a is a terminal holder. It is made in the part 11b.

0012 12 is an electrical contact terminal. This electrical contact terminal 12 has a contact portion as shown in FIG. 14, and a connecting portion 15 continuous to the rear of the contact portion 14. has a structure in which two contact pieces 13 are combined, and the lower surface of the contact part 14 is cut and raised. A lance 14b is provided. The connection part 15 has a crimping piece 16 that stands up in a U-shape. and a core wire crimping part 1 having a crimping piece 18 standing upright in a U-shape. Consists of 9.

[0013] Then, the core wire 21 of the electric wire 20 is crimped with the crimp piece 18 of the core wire crimping part 19. The covering parts 22 are crimped with the crimping pieces 16 of the covering crimping part 17 to make electrical contact with the electric wire 20. Terminal 12 is connected.

[0014] Then, the contact portion 14 of the electrical contact terminal 12 is inserted into the terminal insertion portion 4, and the locking member 9 is inserted into the locking member insertion hole 7, and the inclined surface 11a of the locking member 9 is inserted into the electrical contact terminal 12. is brought into contact with the end 17a of the covering crimping part 17, and the covering pressure is increased by moving the locking member Bring the terminal holding part 11b into contact with the end 17a of the fitting part 17 and press the electrical contact terminal 12. lower the contact portion 14, press the end surface 14c of the contact portion 14 against the end surface portion 5 of the terminal insertion hole 4, and By engaging the lance portion 10 with the lance 14b of the electrical contact terminal 12, the electric wire 20 is connected to the male connector 1.
