A lance part 6 stands up on the left side of the bottom part 5, and a lance part 6 is provided at the end of the lance part 6. A locking protrusion 7 is formed. Then, the lance part 5 is fitted with the rear side of the engagement protrusion 7. A gap 8 is provided between the recess 4 and the left side wall 4a. In addition, the bottom surface of the fitting recess 4 5 has a terminal insertion hole 9 formed on the right side, and the terminal insertion hole 9 is formed on the right side of the opening 10 of the fitting recess 4. A locking protrusion 11 is provided protruding from the.

[0011] 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 connection part 15 is a U-shaped pressure A core wire having a covering crimping part 17 having a crimping piece 16 and a crimping piece 18 standing up in a U-shape. It consists of a crimp part 19.

0012 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.

[0013] In this case, the rear end portion of the cover crimping portion 17 of the electrical contact terminal 12 is connected to the first locking portion 23. Therefore, the rear end portion of the contact portion 14 serves as the second locking portion 24.

[0014] Further, 25 is an insertion member, and this insertion member 25 is a block-shaped terminal regulating portion 2. A lance regulating portion 27 is provided protruding from the end of the lance 6.

[0015] Then, the electrical contact terminal 12 and the insertion member 25 are inserted into the fitting recess 4 of the connector body 3. After insertion, the electric wire 20 is connected to the male connector 1.

[0016] That is, the contact portion 14 of the electrical contact terminal 12 is connected to the right side wall portion 4b of the fitting recess 4. the locking protrusion 11 of the opening 10 of the socket body 3 for electrical connection. It locks into the first locking part 23 on the connecting part 15 of the contact terminal 12, and locks into the locking protrusion of the lance part 6. The holder 7 is locked to the second locking part 24 on the contact part 14 of the electrical contact terminal 12. this In this state, insert the insertion member 12 into the fitting recess 4 as shown in FIG. The regulating part 27 is connected between the back side of the engaging protrusion 7 of the lance part 5 and the left side wall 4a of the fitting recess 4. At the same time, the terminal regulating portion 26 is inserted into the gap 8 between This terminal regulating portion 26 is interposed between the electrical contact terminal 12 and the electrical contact terminal 12 . The cover crimping portion 17 is held down to prevent the electrical contact terminal 12 from moving, and the locking protrusion 11 is 1, and the lance regulating part 26 prevents the lance part 6 from escaping. This ensures that the locking protrusion 7 is securely locked to the second locking portion 24 by preventing the locking projection 7 from bending.

[0017] The female connector 2 is equipped with a connector body 28 made of an insulator. The main body 28 is provided with a fitting part 29, and a terminal on a bottom part 30 of the fitting part 29 is provided. A terminal 32 is attached to the attachment part 31, and the terminal 32 protrudes into the fitting part 29. . An electric wire 33 is connected to this terminal 32.

[0018] Therefore, when the male connector 1 is inserted and fitted into the fitting part 29 of the female connector 2, , a terminal 32 is inserted into the contact portion 14 of the electrical contact terminal 12, and this terminal 32 becomes a contact piece. 13 and continuity is established.

[0019] In some cases, each insertion member 25 is independent as shown in FIG. 6, but as shown in FIG. As shown in FIG. 7 with the thin wall portion 34, and a plurality of insertion members 25 are connected in a row. , the lance regulating part 27 is connected to the rear side of the engagement protrusion 7 of the lance part 6 and the left side wall of the fitting recess 4. After inserting the gap 8 between 4a and 4a, as shown in FIG. You can also do this.

[0020] According to the above embodiment, the locking protrusion 11 on the opening side of the socket body 3 is electrically connected. The first locking part 23 of the terminal 12 and the locking protrusion 7 of the lance part 6 Double locking is possible with the second locking that locks the electric contact terminal 12 to the second locking portion 24 of the electrical contact terminal 12. In addition, the electrical contact terminal 12 can be held down by the terminal regulating portion 26 of the insertion member 25. , prevents movement of the electrical contact terminal 12 and prevents the locking protrusion 11 from engaging the first locking portion 23. In addition, the locking protrusion is ensured by preventing the lance part 6 from escaping with the lance regulating part 27. The locking mechanism 7 securely locks into the second locking part 24, and prevents the electrical contact terminal 12 from coming off. It is possible to improve the degree of
