The vertical direction is defined as the direction shown in fig. 2 as being upward and downward. The left-right direction is defined as the direction shown in fig. 2 as right and left.

As shown in fig. 1, the connector 1 of the embodiment includes a connector housing 20, a female terminal member 10 as a terminal member, and a stopper 40.

[ Structure of connector housing ]

The connector housing 20 is made of synthetic resin. As shown in fig. 2 to 4, the connector housing 20 has a housing 26, a plurality of terminal receiving chambers 21, a lance portion 22 as a primary locking portion, a stopper insertion hole 23, and a hood 25. The housing 26 is formed in a block shape.

The plurality of terminal housing chambers 21 are formed in the housing 26 so as to extend in the front-rear direction. The terminal housing chambers 21 are formed in two stages, upper and lower, and are arranged in plurality in the left-right direction. The rear portion of each terminal housing chamber 21 has a cylindrical shape, and functions as a sealing surface when a rubber plug R is inserted, and the rubber plug R is attached to a distal end portion of an electric wire W described later. The female terminal fitting 10 can be inserted and stored in each terminal storage chamber 21 from the rear.

As shown in fig. 3, the lance 22 is provided in a cantilever shape toward the front on the upper surface of each terminal housing chamber 21. The lance portion 22 is elastically deformable in the up-down direction. The lance 22 is engaged with the female terminal 10 housed in the terminal housing 21 at a normal position, thereby preventing the female terminal 10 in the terminal housing 21 from coming off.

As shown in fig. 4, the stopper insertion hole 23 is formed to penetrate in the lateral direction at the front-rear direction central portion of the housing 26. The stopper insertion holes 23 communicate with the respective terminal housing chambers 21 (see fig. 3). A pair of engaged portions 24 are provided on the front inner surface and the rear inner surface of the right end portion of the stopper insertion hole 23, and the pair of engaged portions 24 face each other and protrude so as to approach each other.

As shown in fig. 1, the cover 25 is cylindrical and is provided so as to cover the upper, lower, left, and right of the housing 26. The cover 25 extends forward from the outer periphery of the rear end portion of the housing 26. A lock arm 27 is provided at a central portion in the left-right direction of the upper surface of the cover 25, and the lock arm 27 is used to lock the mating housing and the connector housing 20, not shown, in a fitted state. The left side of the cover 25 is open with an introduction opening 28, and the stopper 40 passes through the introduction opening 28 when the stopper 40 described later is assembled.

[ Structure of female terminal part ]

The female terminal part 10 is formed by punching a metal plate material into a predetermined shape and then bending the metal plate material. As shown in fig. 5, the female-side terminal member 10 has a square cylindrical portion 12 and a cylinder (barrel) 13. The square tube portion 12 has a tubular shape, and accommodates therein a contact piece 11 that contacts a protruding piece (not shown) of the mating male terminal fitting. The tube 13 is provided at the rear end portion of the female terminal member 10, and is fastened to the end of the wire W through which the rubber plug R is inserted together with the cylindrical rubber plug R.

A stepped portion 14 is formed at the rear end edge of the square tube portion 12. The step portion 14 can lock a drop-off preventing portion 43F of a stopper body 43 described later. A lance locking protrusion 17 is provided at the front end of the upper surface of the square tube 12, and the lance locking protrusion 17 is a detected portion formed by overlapping two sheets of sheet metal. The lance locking protrusion 17 can be locked to the tip of the lance 22 disposed at the rear. A curved surface C is formed at the front end of the square tube 12, and is continuous with the front surface of the square tube 12, and is formed in a quarter circular arc shape continuous with the upper surface of the square tube 12 and the front surface of the square tube 12.

[ Structure of stopper ]

The stopper 40 is made of synthetic resin. As shown in fig. 6 and 7, the stopper body 40 includes a front wall portion 40D covering the front surface of the housing 26, a side wall portion 40C covering the left side surface as viewed from the front, an upper wall portion 40A covering the upper surface, a lower wall portion 40B covering the lower surface, and a stopper body main body 43. The front wall portion 40D has a function of stopping the front of the female terminal fitting 10 inserted into the terminal housing chamber 21 when the stopper 40 is assembled to the housing 26.

A plurality of tab insertion holes 44 are formed in the front wall portion 40D in an arrangement opening corresponding to each terminal housing chamber 21, and tabs (not shown) of the male-side terminal fitting are inserted into the tab insertion holes 44. A plurality of jig insertion holes 45 are formed in the front wall portion 40D so as to open to the upper right of each of the tab insertion holes 44. A jig for releasing the locking of the lance 22 to the female terminal 10 is inserted into each jig insertion hole 45. The moving direction of the stopper 40 when the stopper 40 is assembled to the housing 26 is right. Therefore, the jig insertion hole 45 is disposed at a position separated from the tab insertion hole 44 in the left-right direction intersecting the moving direction of the stopper 40.

As shown in fig. 7, the stopper body 43 is cantilevered rightward from the side wall portion 40C. The stopper body 43 has a shape and size that can be fitted into the stopper body insertion hole 23. As shown in fig. 8, two through holes 43D and 43E penetrating in the front-rear direction are formed in the stopper body 43 in a laterally aligned manner. The through hole 43D is configured to: the stopper body 43 is normally inserted into the stopper body insertion hole 23, and communicates with the three terminal housing chambers 21 disposed on the left side of the upper stage. The through hole 43E is configured to: the stopper body 43 is normally inserted into the stopper body insertion hole 23, and communicates with the three terminal housing chambers 21 disposed on the right side of the upper stage.

Three downward protruding retaining portions 43F are provided on the upper edges of the through holes 43D and 43E, respectively, in a laterally aligned manner. Seven drop-off preventing portions 43F are provided on the lower surface of the stopper body 43 in a line in the left-right direction, and the drop-off preventing portions 43F protrude downward. When the stopper body 43 is normally inserted into the stopper body insertion hole 23, each of the retaining portions 43F enters the corresponding terminal accommodating chamber 21 from the left. The retaining portions 43F are arranged so as to be engageable with the rear portions of the stepped portions 14 of the square tube portion 12 of the female terminal fitting 10 inserted into the terminal housing chamber 21. Accordingly, the female terminal fitting 10 is prevented from coming off in the terminal housing chamber 21 in two stages.

As shown in fig. 7, a plurality of locking recesses 43G are provided in upper portions of the front and rear sides of the right end portion (tip end portion) of the stopper body 43. On the front side of the stopper body 43, two locking concave portions 43G are formed recessed rearward and aligned in the left-right direction. On the rear side of the stopper body 43, two locking concave portions 43G are formed recessed forward and aligned in the left-right direction. The portion in which the rear locking concave portion 43G is formed in a cantilever shape rightward (see fig. 1) and can be elastically deformed in the front-rear direction.

[ assembling step of connector ]

Next, an example of the assembly process of the connector 1 will be described. The stopper 40 is assembled from the left with respect to the housing 26. Specifically, the stopper body 40 is attached to the housing 26 by inserting the stopper body 43 into the stopper body insertion hole 23 (see fig. 10) while the front wall portion 40D is along the front end of the housing 26 (see fig. 11).

When the stopper body 43 is inserted into the stopper body insertion hole 23, the engaged portion 24 of the housing 26 is engaged with the engagement recess 43G on the right side (distal end side) of the stopper body 43 (see fig. 10). Accordingly, the stopper 40 is held at the temporary locking position (see fig. 9). At this time, each of the tab insertion holes 44 of the front wall portion 40D is offset leftward with respect to each of the terminal accommodating chambers 21, and each of the tab insertion holes 44 is blocked by the partition wall 29 between the adjacent terminal accommodating chambers 21 (see fig. 11). Further, each of the retaining portions 43F is retracted to the left side of the corresponding terminal housing chamber 21 (see fig. 12). Thus, the stopper 40 held at the temporary locking position allows insertion of the female terminal fitting 10 into each terminal housing chamber 21. At this time, each jig insertion hole 45 is in a state of being matched with the front surface of the lance portion 22 (see fig. 12). Accordingly, the jig can be inserted into each jig insertion hole 45 to release the locking of the lance 22.

Next, the female terminal fitting 10 fixed to the end of the electric wire W to which the rubber plug R is attached is inserted into the terminal housing chamber 21 from the rear of the terminal housing chamber 21. The lance locking projection 17 collides with the lance 22 during the insertion of the female terminal fitting 10 into the terminal housing chamber 21. Then, the lance 22 is deflected upward by the lance locking projection 17. When the female terminal fitting 10 is inserted into the normal position, the lance 22 reaches the rear of the lance locking projection 17 and returns to its deformed state as shown in fig. 13. Accordingly, even if the female terminal fitting 10 moves rearward, the lance locking protrusion 17 is locked with the lance 22, so that the female terminal fitting 10 is primarily locked in the anti-slip state. The rubber stopper R is closely attached to the inner peripheral surface of the rear portion of the terminal housing chamber 21.

At this time, the front surface of the female-side terminal fitting 10 is covered by the front wall portion 40D and is stopped forward. Specifically, as shown in fig. 14, the portion between adjacent tab insertion holes 44 in the front wall portion 40D is entirely opposed to the front surface of the female-side terminal fitting 10. In addition, the portions of the front wall portion 40D adjacent to each other between the tab insertion holes 44, where no taper of the tab insertion holes 44 is formed, are arranged so as to substantially cover the inner side of the left and right inner surfaces of the square tube portion 12 of the female terminal element 10. The lance locking projection 17 faces the jig insertion hole 45 of the stopper 40 held at the temporary locking position (see fig. 13).

As shown in fig. 13, the curved surface C of the female terminal fitting 10 inserted into the terminal housing chamber 21 is continuous with the upper surface of the square tube 12 and the front surface of the square tube 12, and has a quarter circular arc shape. The curved surface C is disposed at the lower end of the jig insertion hole 45 so as to face the jig insertion hole 45 when the front wall 40D is viewed from the front. Further, the lance locking projection 17 is also disposed so as to face the jig insertion hole 45 at this time. The lance locking protrusion 17 is a portion contacted by an inspection probe inserted from the jig insertion hole 45 at the time of conducting inspection for inspecting whether or not each female terminal fitting 10 is inserted into a normal position in each terminal housing chamber 21.

After the completion of the insertion operation of all the female terminal members 10 into the terminal housing chambers 21, a conduction check is performed to check whether or not each female terminal member 10 is inserted into a normal position in each terminal housing chamber 21. In the conduction inspection, the connector 1 in which the stopper 40 is assembled at the temporary locking position is set in the inspection device, and the inspection probe is inserted into the jig insertion hole 45 of the front wall portion 40D of the stopper 40, and it is determined whether or not the inspection probe is in contact with the lance locking protrusion 17 of the female terminal element 10.

Then, the stopper 40 held at the temporary locking position is moved to the main locking position. When the stopper body 40 is pushed rightward from the temporary locking position, the locked portion 24 is disengaged from the locking recess 43G on the right side (distal end side) of the stopper body 43 and locked with the locking recess 43G on the left side (proximal end side) (see fig. 16). Accordingly, the stopper 40 is held at the main locking position (see fig. 15).

In the stopper 40 held at the main locking position, each of the protruding piece insertion holes 44 of the front wall portion 40D is matched with the front surface of the corresponding terminal accommodating chamber 21, and each of the retaining portions 43F is inserted into the corresponding terminal accommodating chamber 21 (see fig. 17). Then, the retaining portions 43F are engaged with the stepped portions 14 of the rear end edge of the square tube portion 12 of the female terminal fitting 10 (see fig. 19). At this time, each jig insertion hole 45 is closed by the partition wall 29 partitioning the adjacent terminal housing chambers 21 (see fig. 18).

Thus, the stopper 40 held at the main locking position is locked with the female terminal 10 at the normal position inserted into the terminal housing chamber 21, and the female terminal 10 is prevented from coming off. The female terminal 10 is doubly locked in the disengaged state by the lance 22 and the disengaged portion 43F. Thus, the assembly of the connector 1 is completed. The stopper 40 can be moved to the temporary locking position by moving leftward from the main locking position. That is, the stopper 40 can be displaced between the temporary locking position and the normal locking position.

Here, when the female terminal member 10 is inserted into the terminal housing chamber 21, the female terminal member 10 may remain in a state where the normal position is not reached (i.e., a half-inserted state), and the worker may go unnoticed and still go into a work of moving the stopper 40 to the normal locking position.

As shown in fig. 20, when the female terminal element 10 is left behind the normal position, the rear end of the square tube 12 enters the stopper insertion hole 23. When the stopper 40 is to be moved to the main locking position in this state, the stopper insertion hole 23 is prevented from being moved to the main locking position by the coming-off preventing portion 43F coming into contact with the rear end portion of the square tube portion 12 from the left. Accordingly, the half-inserted state of the female terminal fitting 10 into the terminal housing chamber 21 can be detected.

Next, the operational effects of embodiment 1 will be described.

The connector 1 of the present disclosure is provided with a housing 26 and a stopper 40. The housing 26 has a plurality of terminal housing chambers 21 into which the female terminal fittings 10 can be inserted from the distal ends, and the female terminal fittings 10 in the terminal housing chambers 21 are prevented from coming off by the engagement of the lance portions 22. The stopper 40 is mounted to the housing 26 so as to be movable between a temporary locking position, in which the stopper 40 allows insertion of the female terminal fitting 10 into the terminal housing chamber 21, and a normal locking position, in which the stopper 40 is locked with the female terminal fitting 10 at the normal position inserted into the terminal housing chamber 21, thereby preventing the female terminal fitting 10 from coming off. The stopper body 40 has a front wall portion 40D, the front wall portion 40D is configured to stopper the female terminal member 10 forward, a tab insertion hole 44 and a jig insertion hole 45 are formed, a tab inserted into the female terminal member 10 is inserted into the tab insertion hole 44, and a jig for releasing the locking of the lance portion 22 is inserted into the jig insertion hole 45. The jig insertion holes 45 are arranged at positions separated from the protruding piece insertion holes 44 in a direction intersecting the moving direction of the stopper 40, and when the stopper 40 is at the temporary locking position, the portions between adjacent protruding piece insertion holes 44 in the front wall portion 40D face the front surface of the female terminal member 10. According to this structure, when the stopper 40 is located at the temporary locking position, the portion between the tab insertion holes 44 is opposed to the front surface of the female-side terminal fitting 10. The portion between adjacent tab insertion holes 44 in the front wall portion 40D is a portion where the jig insertion hole 45 is not present and the thickness dimension is the largest in the front wall portion 40D. Therefore, the front wall portion 40D can sufficiently perform the function of stopping the female terminal member 10 forward. In addition, erroneous insertion of the jig into the tab insertion hole 44 can be prevented.

The female-side terminal fitting 10 of the connector 1 of the present disclosure has a lance-engaging protrusion 17, and the lance-engaging protrusion 17 faces the jig insertion hole 45 when the stopper 40 is located at the temporary engagement position. According to this configuration, by inserting the inspection probe in contact with the lance locking projection 17 of the female terminal fitting 10 through the jig insertion hole 45 to be in conduction with the female terminal fitting 10, it is possible to determine whether or not the female terminal fitting 10 is inserted to the normal position.

When the stopper 40 is in the main locking position, the jig insertion hole 45 of the connector 1 of the present disclosure is closed by the partition 29 partitioning the adjacent terminal housing chambers 21. With this structure, the female terminal members 10 are prevented from being exposed from portions other than the tab insertion holes 44, and the chance of accidental conduction between the female terminal members 10 can be reduced.

The female terminal fitting 10 of the connector 1 of the present disclosure has a curved surface C that is continuous with the front surface of the female terminal fitting 10 and is curved in a direction away from the front wall portion 40D, and the curved surface C is arranged so as to face the jig insertion hole 45 when the stopper 40 is located at the temporary locking position. According to this structure, the jig is prevented from coming into contact with the female terminal fitting 10 by the curved surface C, and smooth insertion of the jig is promoted.
