Description

  The present invention relates to a connector, and in particular, a connector housing having a terminal locking lance that primarily locks a terminal, and is mounted in the connector housing from a direction orthogonal to the longitudinal direction of the terminal to secondary-lock the terminal. The present invention relates to a connector provided with a spacer.

  Conventionally, for example, the connector shown in FIG. 32 is known as the connector described above (Patent Document 1). As shown in the figure, the connector described in Patent Document 1 includes a connector housing 200 provided with a terminal locking lance 201 for primarily locking the terminal 100 accommodated in the terminal accommodating chamber, and a longitudinal direction Y1 of the terminal 100. A retainer 300 (= spacer) that is inserted into the connector housing 200 from the orthogonal direction Y2 and that secondary-locks the terminal 100 is provided.

  As shown in the figure, a terminal locking lance 201 is formed on the front surface of the connector housing 200 on the distal end side in the longitudinal direction Y1 of the terminal 100, in addition to the mating terminal insertion hole 202a into which the mating connector terminal is inserted. A mold punch hole 202b is formed. For this reason, a plurality of holes are formed in the front surface of the connector housing 200, and there is a concern that the strength of the shape is weak.

  In order to solve the above-described problem, for example, a connector as shown in FIG. 33 has also been proposed (Patent Document 2). As shown in the figure, the connector disclosed in Patent Document 2 is orthogonal to the connector housing 200 provided with a terminal locking lance 201 for primarily locking a terminal accommodated in the terminal accommodating chamber, and the longitudinal direction Y1 of the terminal. The spacer 300 is inserted into the connector housing 200 from the direction Y2 and secondarily locks the terminal.

The front part of the connector housing 200 described above is opened, and a mold for molding the terminal locking lance 201 can be removed from the front part opening. The connector further includes a front holder 400 that is fitted into the front opening of the connector housing 200 and has a mating terminal insertion hole 401 formed therein. As described above, since the connector housing 200 provided with the terminal locking lance 201 and the front holder 400 are provided separately, it is not necessary to provide a hole in the front holder 400 for removing the molding die of the terminal locking lance 201. . For this reason, the front part of a connector can be strengthened. However, the connector described in Patent Document 2 has a problem in that the front holder 400 needs to be provided separately from the connector housing 200, which increases the number of parts and increases costs.

(FIG. 1). The left and right side surfaces 16 of the housing body 10 are formed with locking protrusions 16a and 16b that are locked to the temporary locking groove 22a and the main locking groove 22b (locking groove) of the outer cover 20 (see FIG. FIG. 1).

The outer cover 20 covers the distal end side in the longitudinal direction Y1 of the housing body 10, communicates with each terminal accommodating chamber C, and is connected to a mating terminal insertion hole 21a (hereinafter referred to as a terminal insertion hole 21a) into which a mating male terminal is inserted. There a front portion 21 which is molded to cover the left and right side surfaces 16 of the housing body 10, the provisional locking groove 22a, and the locking groove 22b (FIG. 2) the left and right side cover portion 22 which is molded, the mating connector housing ( A lock arm portion 23 formed with a lock projection 23a to be locked to an unillustrated) and a fitting groove 11 provided inside the lock arm portion 23 and formed in the housing body 10 in the mounting direction Y2 The spacer part 24 (FIG. 2) inserted from is integrally formed.

  As described above, the left and right side surfaces 16 of the housing body 10 and the left and right side surface cover portions 22 of the outer cover 20 are respectively provided with locking protrusions 16a and 16b, temporary locking grooves 22a, and main locking grooves 22b. Since the space for the first locking means can be increased as compared with the case where the locking means is provided in the spacer portion 24 and the front portion 21, the locking can be stabilized.

Further, the temporary locking groove 22a and the main locking groove 22b described above are each formed in a straight line from the rear end portion of the outer cover 20 in the longitudinal direction Y1 along the longitudinal direction Y1, as shown in FIG. Thereby, when the outer cover 20 is molded, the temporary locking groove 22a and the main locking groove 22b can be molded with a mold that is pulled out along the longitudinal direction Y1 toward the rear end side in the longitudinal direction Y1. . That, and the left and right side cover 2 2, etc. rear end side of the spacer portion 24 can be pulled out to the mold in the same direction to shape the, without increasing the die cutting direction, Karikakaritomemizo 22a and the locking groove 22b can be molded, and the manufacturing cost can be reduced.

  The spacer portion 24 includes an upper wall 24a and a partition wall 24b (FIG. 2). The upper wall 24a and the partition wall 24b define the mounting direction Y2 of the intermediate portion of the terminal accommodating chamber C (FIGS. 4 and 5). The spacer portion 24 also includes left and right side surface cover portions 22 and a horizontal partition wall 24c (FIG. 2), and the partition wall 24c defines an orthogonal direction Y3 of the intermediate portion of the terminal accommodating chamber C.

  Further, as shown in FIG. 6, the terminal 30 has, for example, a substantially rectangular cylindrical portion 30 a into which the mating male terminal (mating terminal) enters. The terminal 30 has a first locking step portion 31 for the locking lance 13, and a second locking step portion 32 for the spacer portion 24 on the rear side. The 1st latching step part 31 is shape | molded by the rear end of the 1st protrusion 33 (= protrusion part) protrudingly provided by the cylinder part 30a mentioned above. Further, a contact surface 34 for contacting the conduction probe is provided on the distal end side of the first protrusion 33.

  The height L21 from the lower surface of the terminal 30 to the horizontal plane 35 is substantially the same or slightly smaller than the heights L11 and L12 (FIG. 3) in the housing body 10. Further, the height L22 of the first protrusion 33 is slightly larger than the heights L11 and L12 (FIG. 3) in the housing body 10. An electric wire L is crimped and connected to the crimping piece 36 on the rear side of the terminal 30.

  Next, the temporary locking position of the connector described above will be described with reference to FIG. Here, the temporary locking position means that the outer cover 20 is slid toward the housing body 10 and attached to the housing body 10 so that the spacer portion 24 is inserted into the fitting groove 11 of the housing body 10. The locking protrusions 16 a and 16 b formed on the main body 10 are temporarily locked by the temporary locking grooves 22 a of the outer cover 20. In this temporary locking position, the upper surface of the partition wall 14, the upper surface of the partition wall 24b, and the upper surface of the locking lance 13 are connected without any step. Further, in the temporary locking position, as shown in FIG. 6, the height L31 from the lower wall 12 to the portion closest to the lower wall 12 in the partition wall 24b of the spacer portion 24 is the first protrusion 33 of the terminal 30. It is the same as or slightly higher than the height L22. Thereby, the spacer part 24 permits insertion of the terminal 30 with respect to the terminal accommodating chamber C in the temporary locking position.

  In this temporary locking position, the terminal 30 is first inserted into the lower terminal accommodating chamber C. The terminal 30 is inserted into the terminal accommodating chamber C from the rear portion of the housing main body 10 and enters toward the tip along the lower wall 12. When the first protrusion 33 of the terminal 30 enters the locking portion 13a, the locking portion 13a bends upward in the figure, and further enters and the first protrusion 33 enters the tip side from the locking portion 13a. The locking portion 13a is restored downward in the drawing and locked to the first locking step portion 31 of the terminal 30 to temporarily lock the terminal 30, and the terminal 30 is accommodated and held in the terminal accommodating chamber C.

  Next, the case where the terminal 30 is inserted into the upper terminal accommodating chamber C will be described. The terminal 30 is inserted into the terminal accommodating chamber C from the rear part of the housing body 10 and first enters the front part along the upper surface of the rear partition wall 14 and the upper surface of the partition wall 24b of the spacer part 24 in this order. When the first projection 33 of the terminal 30 enters the locking portion 13a, the upper locking portion 13a bends upward in the figure, and further enters, and the first projection 33 enters the tip side from the locking portion 13a. Then, the locking portion 13a is restored downward in the figure and locked to the first locking step portion 31 of the terminal 30 to primarily lock the terminal 30, and the terminal 30 is accommodated and held in the terminal accommodating chamber C. . Further, a protrusion 13a1 protruding toward the tip side is formed at the tip of the locking part 13a. As shown in FIG. 6, the lower surface of the protrusion 13 a 1 is in contact with the upper surface of the first protrusion 33 of the terminal 30.

  As a result of inserting the terminal 30 as described above, as shown in FIG. 6, the first protrusion 33 is accommodated in the terminal accommodating chamber C toward the outer cover 20 in the mounting direction Y2. Further, the locking lance 13 locks the outer cover 20 side behind the contact surface 34 of the terminal 30 and in the mounting direction Y2. Thereby, the contact surface 34 and the latching | locking part 13a are located in a line with the mounting direction Y2 seeing from the front-end | tip part side. Further, at the temporary locking position, the terminal insertion hole 21a and the contact surface 34 are aligned in the longitudinal direction Y1. Further, at the temporary locking position, the terminal insertion hole 21a and the protrusion 13a1 of the locking portion 13a are provided side by side in the longitudinal direction Y1. Thereby, in the temporary locking position, the contact surface 34 and the protrusion 13a1 of the locking lance 13 are exposed through the terminal insertion hole 21a.

  Therefore, if the terminal 30 is mistakenly inserted, a terminal extraction jig (not shown) such as a driver is inserted from the terminal insertion hole 21a at the temporary locking position, and the terminal extraction jig is inserted into the protrusion of the locking lance 13. It can be inserted between the portion 13a1 and the first protrusion 33 of the terminal 30, and the locking lance 13 can be bent upward to release the primary locking of the terminal 30 by the locking lance 13. Thereby, it is not necessary to provide a hole for inserting a terminal extraction jig in the front portion 21 separately from the terminal insertion hole 21a. Moreover, when the locking lance 13 is exposed through the terminal insertion hole 21a at the final locking position, it is necessary to provide the terminal insertion hole 21a larger than the space for inserting the mating terminal, but the terminal insertion hole at the temporary locking position. By exposing the locking lance 13 through 21a, it is not necessary to provide the terminal insertion hole 21a larger than the space for inserting the mating terminal, so that the strength of the front portion 21 can be further increased.

  Finally, the outer cover 20 is further pressed downward and slid. As a result, the temporary locking groove 22a and the locking protrusions 16a and 16b are not locked, and the locking protrusions 16a and 16b formed on the housing body 10 are locked by the main locking groove 22b of the outer cover 20. This is the final locking position. In this final locking position, as shown in FIG. 5, the partition wall 24 b of the spacer portion 24 is locked to the second locking step portion 32 of the terminal 30, and the terminal 30 is secondarily locked. In the upper stage of the terminal accommodating chamber C, the upper wall 24a of the spacer portion 24 is locked to the second locking step portion 32 of the terminal 30, and the terminal 30 is secondarily locked. Thus, in the final locking position, the spacer portion 24 locks the terminal 30, and even if the locking of the terminal 30 by the locking lance 13 is released, the terminal 30 does not come out of the terminal accommodating chamber C. It is like that.

  Further, the front portion 21 of the outer cover 20 is provided with a checker jig insertion hole 21b (exposed hole) for inserting a conduction probe for checking the continuity of the terminal 30 in addition to the terminal insertion hole 21a (see FIG. 5). 6 and FIG. 7). As shown in FIG. 7, the contact surface 34 and the checker jig insertion hole 21b are provided side by side in the longitudinal direction Y1 at the final locking position. Thereby, the contact surface 34 of the terminal 30 is exposed through the checker jig insertion hole 21b at the final locking position. Therefore, after the main locking of the connector is performed, if a conduction probe (not shown) is inserted from the checker jig insertion hole 21b along the longitudinal direction Y1, the contact surface 34 comes into contact with the terminal 30. A continuity check can be performed.

  By the way, even if the checker jig insertion hole 21b is not provided as described above, for example, for the continuity check, the continuity probe is inserted into the cylindrical portion 30a of the terminal 30 from the terminal insertion hole 21a at the main locking position. It is also conceivable to contact the terminal 30. However, in the case of the female terminal 30 as in the present embodiment, the conduction probe must be inserted obliquely so as to contact the inner peripheral surface of the cylindrical portion 30a, and it is difficult to reliably contact the terminal 30. Further, when the conduction probe is brought into contact with the spring in the cylindrical portion 30a, the spring may be deformed.

  Therefore, as in this embodiment, the contact surface 34 that is aligned with the checker jig insertion hole 21b in the longitudinal direction Y1 and intersects the longitudinal direction Y1 is provided on the terminal 30, and is exposed through the checker jig insertion hole 21b. If the conduction probe is inserted from the checker jig insertion hole 21b along the longitudinal direction Y1, the conduction probe and the abutment surface 34 can be reliably and simply brought into contact with each other to perform the conduction check.

  Also, for connectors with a configuration that allows continuity check at the temporary lock position and cannot perform continuity check at the full lock position, if you forget to check the continuity at the time of temporary lock, Although it is necessary to check the continuity by returning to the stop, as described above, if the continuity check can be performed at the main locking position, such a situation does not occur, so the continuity check of the terminal 30 is performed more easily and reliably. Can do.

  According to the connector described above, since the front portion 21 is provided separately from the housing main body 10 in which the locking lance 13 is accommodated, it is necessary to provide the front portion 21 with a hole for extracting a molding die of the locking lance 13. In addition, the strength of the front portion 21 can be increased. In addition, since the spacer portion 24 and the front portion 21 are integrally formed, the number of parts can be reduced and the cost can be reduced.

  Further, according to the connector described above, in the terminal 30, the contact surface 34 is formed on the distal end side of the first protrusion 33, and the first locking that locks the locking lance 13 at the rear end of the first protrusion 33. A step portion 31 is formed. Accordingly, it is not necessary to separately provide a protrusion for forming the contact surface 34 and a protrusion for forming the first locking step 31 for locking the locking lance 13, and the terminal 30. The shape can be simplified.

  Further, in the first embodiment described above, as shown in FIG. 2, the temporary locking groove 22a and the main locking groove 22b are formed by a mold that is pulled out along the longitudinal direction Y1 toward the rear end of the longitudinal direction Y1. However, as shown in FIGS. 8 to 10, it is conceivable to form the temporary locking groove 22a and the main locking groove 22b.

  As shown in the figure, the temporary locking groove 22a is formed so as to penetrate through the punching hole 21c (= through hole) of the molding die of the temporary locking groove 22a provided in the front portion 21 and is long. It is molded along the direction Y1. The main locking groove 22b is formed through the punching hole 21d (= through hole) of the molding die of the main locking groove 22b provided in the front portion 21 and is formed along the longitudinal direction Y1. ing. Thereby, when the outer cover 20 is molded, the temporary locking groove 22a and the main locking groove 22b can be molded with a mold which is directed to the distal end side in the longitudinal direction Y1 and is extracted along the longitudinal direction Y1. That is, the front portion 21 front, the terminal insertion hole 21a, the checker jig insertion hole 21b and the like can be extracted in the same direction as the mold to be molded, and the temporary locking groove 22a and the main locking groove can be formed without increasing the mold cutting direction. The groove 22b can be formed, and the manufacturing cost can be reduced.

  8 to 10, the temporary locking groove 22a and the main locking groove 22b are formed so as to penetrate the left and right side surface cover parts 22, but the temporary locking groove 22a and the main locking groove 22b are formed. The groove 22b may be formed in a concave shape as shown in FIG.

Further, in the example shown in FIGS. 8 to 10, had described the case of forming the left and right side cover portions 2 2 Karikakaritomemizo 22a and the locking groove 22b, engage the left and right side cover portions 2 2 Also in the case where the protrusion is provided, the outer cover can be formed by penetrating through the punched hole provided in the front portion 21 and formed along the longitudinal direction Y1 in the same manner as the temporary locking groove 22a and the main locking groove 22b. It can shape | mold with the metal mold | die pulled along the longitudinal direction Y1 toward the 20 longitudinal direction Y1 front end side.

Second Embodiment Next, a second embodiment of the present invention will be described. FIG. 11 is an exploded perspective view showing the outer cover 20 and the housing body 10 in the second embodiment of the connector of the present invention. 12 is a rear view of the connector in the temporary locking position of the connector shown in FIG. FIG. 13 is a rear view of the connector shown in FIG. 11 at the final locking position. FIG. 14 is a rear view of the connector shown in FIG. 11 in the terminal halfway insertion state. 11 to 14, parts that are the same as those already described in the first embodiment with reference to FIGS. 1 to 10 are given the same reference numerals, and detailed descriptions thereof are omitted.

  The difference between the first embodiment and the second embodiment is that second locking means (main locking protrusions, temporary locking protrusions, locking protrusions) described later are provided. This second locking means will be described below.

  As shown in FIG. 11, the outer cover 20 is provided with a lock arm portion 23 on the outer cover 20 side in the mounting direction Y2. The lock arm portion 23 bends toward the housing body 10 in the mounting direction Y2 when mated with the mating connector housing, allows the mating connector housing to move in the mating direction (ie, the longitudinal direction Y1), and mates with the mating connector housing. It is comprised from the arm part 23b which restores in the state in a position, and the lock protrusion 23a which is provided in the arm part 23b and latches the other party connector housing.

  The outer cover 20 has a pair of lock protection walls 25 provided on both sides of the lock arm portion 23. The pair of lock protection walls 25 are provided from the rear end to the front end along the longitudinal direction Y1. A flange portion 26 that is horizontal in the orthogonal direction Y3 is integrally provided at the rear ends of the pair of lock protection walls 25 in the longitudinal direction Y1. The housing body 10 has a pair of flexible locking arms 19 that protrude along the lock protection wall 25 between the pair of lock protection walls 25. The pair of flexible locking arms 19 can be bent in the orthogonal direction Y3.

  On the lock protection wall 25 side of the flexible locking arm 19, a temporary locking projection 19a and a final locking projection 19b (latched to the locking projection 25a (second locking means) of the outer cover 20). Second locking means) is formed. The temporary locking protrusions 19a and the main locking protrusions 19b are provided such that the protrusion heights increase toward the housing body 10 side in the mounting direction Y2.

  Further, on the side of the flexible locking arm 19 of the lock protection wall 25, as shown in FIG. 12, it is locked with the temporary locking projection 19a of the flexible locking arm 19 at the temporary locking position, as shown in FIG. Thus, a locking projection 25a that locks with the main locking projection 19b of the flexible locking arm 19 is formed at the final locking position. The locking protrusion 25a is provided so that the protrusion height increases as it goes toward the outer cover 20 in the mounting direction Y2.

  Next, the assembly of the connector described above will be described. First, when the outer cover 20 is slid toward the housing body 10 and attached to the housing body 10 so that the spacer portion 24 is inserted into the fitting groove 11 of the housing body 10, the housing is similar to the first embodiment described above. The locking protrusions 16 a and 16 b provided on the main body 10 are temporarily locked by the temporary locking grooves 22 a of the outer cover 20. Further, as shown in FIG. 13, the locking projection 25 a provided on the housing body 10 is temporarily locked with the temporary locking projection 19 a provided on the outer cover 20. Thus, when the housing body 10 and the outer cover 20 are locked at the temporary locking position, the spacer portion 24 allows the insertion of the terminal 30 into the terminal accommodating chamber C.

  In this temporary locking position, the terminal 30 is inserted into the terminal accommodating chamber C. Finally, the outer cover 20 is further pressed and slid toward the housing body 10. As a result, the locking between the temporary locking groove 22a and the locking projections 16a and 16b and the locking between the temporary locking projection 19a and the locking projection 25a are released, and the locking projection provided on the housing body 10 is released. 16 a and 16 b are finally locked in the main locking groove 22 b of the outer cover 20. Further, the locking projection 25 a provided on the housing body 10 is fully locked with the main locking projection 19 b provided on the outer cover 20. Thus, when the housing body 10 and the outer cover 20 are locked at the final locking position, the spacer portion 24 locks the terminal 30 so that the terminal 30 does not come out of the terminal accommodating chamber C.

  In addition, as shown in FIG. 6, when the connector 30 is in the terminal insertion state where the tip of the terminal 30 is not properly inserted to the tip of the terminal accommodating chamber C, the partition wall 24 b of the spacer portion 24 interferes with the horizontal surface 35 of the terminal 30. And cannot be locked at the final locking position. That is, as shown in FIG. 14, in the terminal halfway insertion state, the housing body 10 and the outer cover 20 are in a state between the temporary locking position and the main locking position. In this state, the main locking projection 19b and the locking projection 25a come into contact with each other, and the flexible locking arm 19 bends away from the lock protection wall 25 and is positioned below the lock arm 23.

  Accordingly, the lock arm portion 23 does not bend toward the housing body 10 side in the mounting direction Y2 beyond the flexible locking arm 19. For this reason, the lock arm part 23 cannot bend to the housing body 10 side in the mounting direction Y2, and the movement of the mating connector housing in the fitting direction cannot be permitted. As a result, since it cannot be fitted to the mating connector housing, the terminal halfway insertion state can be easily understood, and the terminal halfway insertion can be prevented beforehand.

  Further, according to the connector of the second embodiment described above, the housing body 10 and the outer cover are respectively provided on the lock protection wall 25 side of the flexible locking arm 19 and the flexible locking arm 19 side of the lock protection wall 25. Second locking means (temporary locking projection 19a, main locking projection 19b and locking projection 25a) for locking the cover 20 at the temporary locking position and the final locking position is provided. Therefore, the second locking means can be provided by utilizing the dead space between the lock arm portion 23 and the lock protection wall 25, and the holding power of temporary locking and main locking is improved while saving space. Can be made.

Third Embodiment Next, a third embodiment of the present invention will be described. FIG. 15 is a rear exploded perspective view showing the outer cover 20 and the housing body 10 in the third embodiment of the connector of the present invention. FIG. 16 is a front oblique view showing the housing main body shown in FIG. FIG. 17 is a rear view of the connector shown in FIG. 15 at the temporary locking position. 18 is a rear view of the connector shown in FIG. 15 in the final locking position. FIG. 19 is a rear view of the connector shown in FIG. 15 in a terminal halfway insertion state. FIG. 20 is a view for explaining a method for releasing the locking of the connector shown in FIG. 15 to 20, parts that are the same as those already described in the first and second embodiments described above with reference to FIGS. 1 to 30 are given the same reference numerals, and detailed descriptions thereof are omitted.

  The differences between the second embodiment and the third embodiment are the configuration of the first locking means, the point that the outer cover 20 is provided with a tapered surface 27, and the locking release portion 19c on the flexible locking arm 19. It is a point provided. This difference will be described below.

  In the third embodiment, as shown in FIGS. 15 and 16, locking protrusions 28 are provided at positions indicated by dotted lines inside the right and left side cover portions 22 of the outer cover 20, and the left and right side surfaces 16 of the housing body 10 are temporarily provided. A locking groove 16c and a main locking groove 16d are provided. In this case, if the locking protrusion 28 is also formed at the rear end portion in the longitudinal direction Y1 of the outer cover 20 and is formed along the straight line in the longitudinal direction Y1, the outer protrusion 20 is similar to the locking grooves 22a and 22b. The cover 20 can be molded by a mold that is extracted from the rear end portion in the longitudinal direction Y1 along the longitudinal direction Y1.

  Further, a taper surface 27 that is separated from the flexible locking arm 19 toward the rear end side in the longitudinal direction Y1 is provided on the wall surface of the lock protection wall 25 on the flexible locking arm 19 side. By providing this tapered surface 27, the wall surface on the rear end side in the longitudinal direction Y1 with respect to the wall surface W1 provided with the locking projection 25a as the second locking means, that is, the tapered surface 27 is a flexible locking arm. 19 is provided to be separated from And the latch release | release part 19c of the flexible latching arm 19 is provided so that it may protrude in the longitudinal direction Y1 rear end side rather than the wall surface W1 in which the latching protrusion 25a is provided.

First, when the outer cover 20 is slid toward the housing body 10 and attached to the housing body 10 so that the spacer portion 24 is inserted into the fitting groove 11 of the housing body 10, the locking protrusion provided on the outer cover 20 is provided. The portion 28 is temporarily locked by a temporary locking groove 16 c provided in the housing body 10. Further, as shown in FIG. 17, the locking projection 25 a provided on the housing body 10 is temporarily locked with the temporary locking projection 19 a provided on the outer cover 20. Thus, when the housing body 10 and the outer cover 20 are locked at the temporary locking position, the spacer portion 24 allows the insertion of the terminal 30 into the terminal accommodating chamber C.

  In this temporary locking position, the terminal 30 is inserted into the terminal accommodating chamber C. Finally, the outer cover 20 is further pressed and slid toward the housing body 10. As a result, the locking between the temporary locking groove 16c and the locking projection 28 and the locking between the temporary locking projection 19a and the locking projection 25a are released, and the locking projection 28 provided on the outer cover 20 is removed from the housing. The main locking is performed in the main locking groove 16 d of the main body 10. Further, the locking projection 25 a provided on the housing body 10 is fully locked with the main locking projection 19 b provided on the outer cover 20. Thus, when the housing body 10 and the outer cover 20 are locked at the final locking position, the spacer portion 24 locks the terminal 30 so that the terminal 30 does not come out of the terminal accommodating chamber C.

  Further, as shown in FIG. 19, in a state where the housing body 10 and the outer cover 20 are between the temporary locking position and the main locking position, that is, in the terminal halfway insertion state, similarly to the second embodiment described above. The flexible locking arm 19 can be bent in the direction away from the lock protection wall 25 to prevent the lock arm portion 23 from being bent toward the housing body 10 in the mounting direction Y2.

  Next, unlocking will be described. At the time of unlocking, as shown in FIG. 20, a finger is put into a gap formed between the taper surface 27 and the unlocking portion 19 c of the flexible locking arm 19, and the pair of flexible locking arms 19.

When there is no gap between the lock protective wall 25 and the flexible locking arm 19 as in the second embodiment, the side where the flexible locking arm 19 is separated from the lock protective wall 25 using a release jig. It was necessary to bend. Moreover, since a pair of flexible locking arms 19 are provided in the left-right direction Y3, it is very difficult to bend the pair of flexible locking arms 19 simultaneously.

  According to the third embodiment, a gap is formed between the tapered surface 27 and the locking release portion 19c, and can be easily performed using a finger of one hand without using a special jig as in the second embodiment. The locking of the flexible locking arm 19 can be released.

  In the third embodiment described above, by providing the tapered surface 27, the wall surface on the rear end side in the longitudinal direction Y1 with respect to the wall surface W1 provided with the locking projection 25a, that is, the tapered surface 27 is flexible. Although provided so as to be separated from the stop arm 19, the present invention is not limited to this. For example, it is conceivable to provide a step such that the wall surface on the rear end side in the longitudinal direction Y1 from the wall surface W1 is separated from the flexible locking arm 19.
