  As shown in FIGS. 4A and 4B and FIGS. 5A and 5B, the housing main body 14 has an opening 61 in the bottom wall 14a. As a result, the terminal accommodating chamber 21 formed in the housing main body 14 has an intermediate portion in the longitudinal direction opened at the opening 61, and the crimping portion 33 side of the female terminal 31 accommodated in the terminal accommodating chamber 21 is exposed. .

  As shown in FIGS. 6A, 6B, 7A, and 7B, the housing body 14 is formed with an opening 61 so that a part of the bottom wall 14a is removed. In a side view, a part of the side walls 14b on both sides and a part of the partition wall 21a partitioning the terminal accommodating chamber 21 are removed in a concave shape. In the opening 61 formed in the housing main body 14, the wall surface on the front end side of the housing main body 14 is a rotation restricting surface 62, and the wall surface on the rear end side of the housing main body 14 is a locking surface 63. The rotation restricting surface 62 is arranged on the rear end side of the electrical connection portion 32 of the female terminal 31 accommodated in the terminal accommodating chamber 21 and locked to the lance portion 22 or slightly on the rear end side. Further, a stepped portion 64 is formed at the edge of the wall surface of the opening 61 on the front end side of the housing main body 14. A pair of locking portions 65 are formed on the edge of the locking surface 63. These locking portions 65 are formed on both side portions of the housing main body 14 and protrude toward the distal end side of the housing main body 14.

  The retainer 41 is formed in a rectangular shape in plan view, and has a bottom wall portion 41a and a side wall portion 41b. In the retainer 41, chamfered portions 42 are formed at corners of the bottom wall portion 41a and the side wall portion 41b. A hinge 44 is provided between the retainer 41 and the housing body 14. The hinge 44 is connected to the edge of the stepped portion 64 formed in the opening 61 and the end of the retainer 41 on the front end side of the housing body 14. As a result, the retainer 41 is connected to the housing main body 14 at the front end side of the housing main body 14 through the hinge 44 over the width direction. The hinge 44 has chamfered portions 45 formed on both sides thereof.

  The housing main body 14, the retainer 41, and the hinge 44 are integrally formed. The hinge 44 is formed thin and can be deformed. As a result, the retainer 41 is rotatable about the axis along the width direction with respect to the housing main body 14 with the end on the distal end side of the housing main body 14 as the base end.

  And the opening part 61 of the housing main body 14 is open | released by rotating the retainer 41 in the direction away from the housing main body 14, and is closed by rotating the retainer 41 to the housing main body 14 side. As described above, the retainer 41 can be moved between an open position where the opening 61 is opened (see FIG. 4B) and a closed position where the opening 61 is closed (see FIG. 4A). ing.

  In a state where the retainer 41 is disposed at the closed position and the opening 61 is closed, the surface of the bottom wall 14a of the housing body 14 and the surface of the bottom wall portion 41a of the retainer 41 are flush with each other, and the side wall 14b of the housing body 14 And the surface of the side wall 41b of the retainer 41 are flush with each other. Further, in a state where the retainer 41 is disposed at the closed position and the opening 61 is closed, the chamfered portion 42 of the retainer 41 and the chamfered portion 45 of the hinge 44 are formed with respect to the corner portion 16 where the chamfered portion of the housing main body 14 is applied. Are continuous in a straight line. As described above, the retainer 41 is fitted into the opening 61 without protruding from the outer shape of the housing body 14 in the closed position where the opening 61 is closed. The retainer 41 arranged at this closed position constitutes a part of the outer wall of the housing body 14. Further, the retainer 41 is disposed at the closed position and fitted into the opening 61, so that the retainer 41 closes the opening 61 of the housing main body 14, and part of each terminal accommodating chamber 21 of the housing main body 14. Configure.

  The retainer 41 has a pair of lock claws 46 at the free end opposite to the connecting portion with the housing main body 14 by the hinge 44. These lock claws 46 are formed in a tapered shape in a sectional view with a thickness decreasing toward the tip. The lock claw 46 is formed on both sides of the retainer 41. Furthermore, a jig hole forming recess (recess) 47 is formed at the free end of the retainer 41 at the center in the width direction. A thick portion 48 is formed between the lock claw 46 and the jig hole forming recess 47 at the free end of the retainer 41. The thick portion 48 is formed to be thicker than the tapered lock claw 46.

  In a state where the retainer 41 is disposed at the closed position and the opening 61 is closed, the lock claw 46 is locked to the locking portion 65 on the housing body 14 side. Thereby, the retainer 41 is maintained in the state fitted in the opening 61. When the retainer 41 is disposed at the closed position, the free end of the retainer 41 is disposed at a position facing the locking surface 63 of the opening 61, and the thick portion 48 of the retainer 41 is placed on the locking surface 63 of the opening 61. On the other hand, it is arranged without a gap. Further, when the retainer 41 is arranged at the closed position, a jig hole (hole) surrounded by the jig hole forming recess 47 and the locking surface 63 is formed between the retainer 41 and the locking surface 63 of the opening 61. Part) H is formed. In this jig hole H, a rod-shaped jig (not shown) can be inserted. The retainer 41 inserts a jig into the jig hole H, engages the tip of the jig with the surface of the retainer 41 opposite to the bottom wall portion 41a, and pulls it up. The locked state is released.

  Here, the jig hole forming recess 47 is surrounded by thick portions 48 on both sides thereof. Therefore, the tip of the rod-shaped jig inserted into the jig hole H formed by the jig hole forming recess 47 and the locking surface 63 is directly below the jig hole H in a predetermined direction by the thick part 48. It will guide toward the partition 21a and will contact | abut to the partition 21a. Thereby, the malfunction that the jig | tool inserted in the jig | tool hole H penetrate | invades in the terminal storage chamber 21, contacts the crimp part 33 of the female terminal 31, and is damaged reliably is suppressed.

  The retainer 41 has a pair of locking projections 51 on the side opposite to the bottom wall portion 41a. These locking projections 51 are formed over the longitudinal direction of the retainer 41. These locking projections 51 have a width dimension slightly smaller than the width dimension of the terminal accommodating chamber 21 of the housing body 14. As for the latching convex part 51, the end surface of the base end side of the retainer 41 to which the hinge 44 is connected is a contact surface 52. Moreover, the latching convex part 51 is made into the flank 53 in which the end surface of the free end side opposite to a base end side inclined gradually to the base end side toward the protrusion direction. The locking projection 51 has a projecting dimension that is as large as possible as long as the bottom surface 51 a does not contact the female terminal 31 accommodated in the terminal accommodating chamber 21.

  When the retainer 41 in the open position is rotated to the closed position and the retainer 41 is fitted into the opening 61, the locking convex portion 51 enters and fits into each terminal accommodating chamber 21 of the housing body 14. In this state, the contact surface 52 of the locking projection 51 contacts the rotation restricting surface 62 of the opening 61, and the rotation of the retainer 41 is restricted. And the latching convex part 51 fitted by the terminal storage chamber 21 is arrange | positioned at the rear end side of the electrical connection part 32 of the female terminal 31 accommodated in the terminal storage chamber 21 and latched by the lance part 22. FIG. . Thereby, the female terminal 31 accommodated in the terminal accommodating chamber 21 is in a state where the electrical connection portion 32 is locked by the locking convex portion 51 of the retainer 41 as well as locking by the lance portion 22. Further, when the retainer 41 is disposed at the closed position, the respective locking projections 51 are fitted into the respective terminal receiving chambers 21 and the partition walls 21 a that partition the terminal receiving chambers 21 between the locking protruding portions 51. Are fitted. Thereby, the retainer 41 is also restricted from moving in the width direction with respect to the housing body 14.

  Further, since the locking convex portion 51 is formed as a flank 53 whose end surface on the free end side is gradually inclined toward the base end side in the protruding direction, when the retainer 41 is rotated to the closed position, the opening portion It fits into the terminal accommodating chamber 21 without interfering with the locking portion 65 of the locking surface 63 of 61.

  Next, a case where the female terminal 31 is attached to the housing main body 14 of the female housing 12 will be described.

  FIG. 8 is a cross-sectional view taken along the longitudinal direction of the connector for explaining the mounting of the female terminal to the housing body.

  As shown in FIG. 8, the female terminal 31 with the bottom side facing upward is inserted from the rear end side into the terminal accommodating chamber 21 of the housing body 14 in a state where the retainer 41 is disposed at the open position. As described above, when the female terminal 31 is inserted into the terminal accommodating chamber 21, the projection 23 of the lance portion 22 formed on the housing body 14 engages the locking claw 32 a formed on the electrical connection portion 32 of the female terminal 31. To do. Thereby, the female terminal 31 is accommodated in the terminal accommodating chamber 21 in a state in which the female terminal 31 is locked by the lance portion 22 and is prevented from coming off.

  Next, the retainer 41 in the open position is rotated toward the closed position, and the retainer 41 is fitted into the opening 61 of the housing body 14. Then, the latching convex portion 51 of the retainer 41 enters and fits into each terminal accommodating chamber 21 of the housing body 14, and the rear end of the electrical connection portion 32 of the female terminal 31 accommodated in the terminal accommodating chamber 21 is the retainer 41. It is locked by the contact surface 52 of the locking projection 51.

  Thus, in the connector 11, the female terminal 31 is double-locked by the lance portion 22 of the housing body 14 and the locking convex portion 51 of the retainer 41. Therefore, even if a tensile force acts on the insulated wire 36 connected to the female terminal 31, the female terminal 31 is maintained in the terminal accommodating chamber 21 without coming out of the female housing 12.

  Here, when the female terminal 31 is locked by the retainer 41, the lance portion 22 may not be locked to the female terminal 31 inserted into the terminal accommodating chamber 21. is there. Even in such a case, by rotating the retainer 41 to the closed position, the contact surface 52 of the locking projection 51 of the retainer 41 contacts the rear end of the electrical connection portion 32 of the female terminal 31. Push toward the front end side of the housing body 14. As a result, the electrical connection portion 32 of the female terminal 31 is securely double-locked by the projection 23 of the lance portion 22 and the locking projection 51 of the retainer 41.

  Next, the case where the connector 11 is joined to the mating connector 1 will be described.

  In order to join the connector 11 to the mating connector 1, the tip of the female housing 12 of the connector 11 is brought close to the tip of the male housing 2 of the mating connector 1. Then, the fitting portion 13 of the female housing 12 is inserted into the fitting recess 3 of the hood portion 4 of the male housing 2.

  Then, the tab (not shown) of the male terminal of the male housing 2 is inserted and held from the insertion hole 24 on the distal end side of the housing main body 14 of the female housing 12 into the electrical connection portion 32 of the female terminal 31, and the male terminal and female The terminal 31 is electrically connected. In this state, the lock claw 17 of the lock arm 18 formed in the lock portion 15 of the female housing 12 engages the engagement hole formed in the hood portion 4 of the male housing 2, and the female housing 12 and the male housing 12 is maintained.

  The female housing 12 is formed in an asymmetric shape when viewed from the front. Therefore, joining to the male housing 2 having the fitting recess 3 having a cross-sectional shape different from the cross-sectional shape of the fitting portion 13 of the female housing 12 is prohibited. That is, the connector 11 can be joined only to the regular mating connector 1.

  Here, when the connector 11 is joined to the mating connector 1, the retainer 41 may not be completely fitted into the opening 61 of the housing body 14. Even in such a case, by fitting the fitting portion 13 of the female housing 12 into the fitting recess 3 of the hood portion 4 of the male housing 2, the hood portion 4 of the male housing 2 becomes the bottom wall of the retainer 41. The retainer 41 is rotated to the housing main body 14 side and is securely fitted into the opening 61.

  In order to remove the connector 11 joined to the mating connector 1 from the mating connector 1, the pressing portion 19 at the rear end of the lock arm 18 is pressed. Then, the entire lock arm 18 is elastically deformed so as to be bent, and the lock due to the engagement of the engagement hole by the lock claw 17 of the lock arm 18 is released.

  In this state, the connector 11 is pulled away from the mating connector 1. Then, the fitting part 13 of the female housing 12 is pulled out from the fitting recess 3 of the hood part 4 of the male housing 2. Thereby, the tab of the male terminal is pulled out from the electrical connection portion 32 of the female terminal 31, and the conductive connection between the female terminal 31 and the male terminal is released.

  As described above, according to the connector 11 according to the present embodiment, the female terminal accommodated in the terminal accommodating chamber 21 by disposing the retainer 41 in the closed position and fitting the retainer 41 into the opening 61 of the housing body 14. 31 can be locked by the locking projection 51 of the retainer 41 together with the locking by the lance 22. Moreover, by placing the retainer 41 in the closed position, the free end of the retainer 41 can be locked to the locking surface 63 of the opening 61 by the locking portion 65, and the retainer 41 is securely fixed to the housing body 14. be able to. In addition, when the retainer 41 is disposed at the closed position, a jig hole H is formed between the free end of the retainer 41 and the locking surface 63 of the opening 61. Therefore, the jig is inserted into the jig hole H. Then, the retainer 41 can be pulled away from the housing main body 14 to release the lock by the locking portion 65 and rotate to the open position. Thereby, the retainer 41 can be removed as needed and the female terminal 31 can be easily remounted.

  Further, the end of the retainer 41 on the front side in the insertion direction of the female terminal 31 to the terminal accommodating chamber 21 is a base end connected to the housing body 14 by a hinge 44. Therefore, by rotating the retainer 41 toward the closed position, the female terminal 31 that is not completely inserted into the terminal accommodating chamber 21 is pushed forward by the locking projection 51 in the insertion direction, and is engaged by the lance portion 22. It can be accommodated in a predetermined position to be stopped.

  In addition, when the insulated wire 36 connected to the female terminal 31 is pulled and a tensile force acts on the female terminal 31 in the direction of coming out of the terminal accommodating chamber 21, the thick portion 48 of the retainer 41 is opened. It contacts and opposes the locking surface 63 of 61. Therefore, the locking force of the female terminal 31 by the retainer 41 can be increased.

  In addition, a rotation restricting surface 62 that restricts the rotation of the retainer 41 by contacting the retaining convex portion 51 of the retainer 41 is provided in the opening 61, and the rotation restricting surface 62 is provided on the retaining convex portion of the retainer 41. The female terminal 31 locked by 51 is disposed at the locking position.
