  When the cylindrical bodies 24, 24 of the female connector 2C of FIG. 16 are inserted from the opening 5 (FIG. 15) of the male connector 1C, first, as shown in FIG. The second locking portion 50C of the male connector 1C enters the socket housing 21C through the above-described jig insertion hole 37 of 2C, and the upper portion of the claw 64a of the distal end portion 64 in the second locking means 60C of the female connector 2C. However, it contacts the lower part of the front-end | tip part 53 in 2nd latching | locking part 50C of 1 C of male connectors. When the female connector 2C is further inserted, as shown in FIG. 21B, the second locking means 60C of the female connector 2C bends downward, and the claw 64a of the tip 64 is connected to the tip 53 of the second lock 50C. Located directly below. When the female connector 2C is further inserted and the fitting of both the connectors 1C and 2C is completed, as shown in FIG. 21C, the distal end portion 64 of the second locking means 60C is connected to the distal end portion 53 of the second locking portion 50C. The second locking means 60C that has come out rearward and has been bent becomes horizontal as it was, and the claw 64a is engaged with the rear edge of the front end portion 53 of the second locking portion 50C. The female connector 2C is prevented from coming off from 1C.

  If the retaining is only the engagement between the first locking portions 11 and 11 and the first locking means 28 and 28 (FIG. 9) as in the prior art, the electric wire connected to the female connector 2C with respect to the male connector 1C. When 45 is pulled strongly in the direction in which it is prevented from coming off (the left direction in FIGS. 9 and 10), the effect of retaining it is not sufficient. However, in the fifth and sixth embodiments, as apparent from the engagement state between the tip 53 of the second locking portion 50C and the claw 64a of the tip 64 of the second locking means 60C shown in FIG. 21C. The female connector 2C cannot be separated from the male connector 1C simply by pulling the electric wire 45 connected to the female connector 2C.

Since the stop means 28, 28 (FIG. 9) and the second locking means 60C are provided, the effect of retaining is improved. In particular, with respect to retaining by engagement between the tip 53 of the second locking portion 50C and the claw 64a of the tip 64 of the second locking means 60C, the socket housing 21C is not directly pulled by the operator. And will not be released. Therefore, even if the electric wire 45 connected to the female connector 2C is accidentally pulled, the female connector 2C does not come out of the male connector 1C.

  In addition, since the front-end | tip part 53 of the 2nd latching | locking part 50C of 1 C of male connectors of 5th Embodiment is inserted in the socket housing 21C from the insertion hole 37 of the jig | tool which also has the conventional female connector, 5th Embodiment The male connector 1C is not limited to the female connector 2C of the sixth embodiment, and a conventional female connector can be inserted and fitted. Similarly, the female connector 2C of the sixth embodiment can be inserted and fitted into a conventional male connector.

  Next, the male connector which is 7th Embodiment of this invention is demonstrated. As shown in the perspective view of FIG. 22, the male connector 1D is different from the male connector 1A (FIG. 1) of the first embodiment only in the configuration of the second locking portion 50D. Are denoted by the same reference numerals and description thereof is omitted.

  In addition to the first locking portions 11, 11 (FIG. 3), the male connector 1D is engaged with a second locking means 60D (FIG. 23) of a female connector 2D of an eighth embodiment to be described later. A locking portion 50D is provided. More specifically, the base housing 3D has a second locking portion 50D, and the second locking portion 50D is on the center of the front portion (that is, the opening 5 side) of the top plate 14 of the base housing 3D. Further, it is integrally formed as a part of the base housing 3D, and protrudes upward from the top plate 14 over a part in the left-right direction of the top plate 14 of the base housing 3D. The second locking portion 50 </ b> D may protrude upward from the top plate 14 over the entire left-right direction of the top plate 14. Further, the front surface 57 of the second locking portion 50D has a slope that becomes higher toward the rear. In the first example of the seventh embodiment, the second locking portion 50D is trapezoidal in a side view, and the front end coincides with the front end of the top plate 14 (FIG. 25A). As an example, it may be a triangle in a side view, and the front end may be behind the front end of the top plate 14. Further, it may be a pentagon when viewed from the side.

  In the first example of the seventh embodiment shown in FIG. 25A, the angle α that the rear surface 58 of the second locking portion 50D forms with the top plate 14 of the base housing 3D across the space is an acute angle. “With a space in between” means “measure backward (in the clockwise direction in FIG. 25A) for the male connector 1D”, and is also an acute angle in the second example of FIG. 25B. That is, the second locking portion 50D has a shape with a “barb” for the withdrawal of the female connector 2D from the male connector 1D. However, although the reason for this angle α will be described later, as in the third example shown in FIG. 27A, at least the upper portion 58a of the rear surface 58 of the second locking portion 50D is sandwiched between the top plates of the base housing 3D. An obtuse angle or a right angle with 14 is preferable. As in the fourth example shown in FIG. 27B, the entire rear surface 58 of the second locking portion 50D may form an obtuse angle or a right angle, particularly an obtuse angle, with the top plate 14 of the base housing 3D across the space.

  Next, a female connector which is an eighth embodiment of the present invention and which is inserted into and fitted into the male connector 1D of the seventh embodiment will be described. As shown in the perspective view of FIG. 23, the female connector 2D is different from the female connector 2A (FIG. 2) of the second embodiment only in the configuration of the second locking means 60D. Are denoted by the same reference numerals and description thereof is omitted.

  In addition to the first locking means 28, 28, the female connector 2D is provided with second locking means 60D that engages with the second locking portion 50D (FIG. 22) of the male connector 1D. More specifically, the socket housing 21D has the second locking means 60D, and the second locking means 60D includes a plate-like movable part 65 extending in parallel with the socket part 32 (FIG. 7). A leg portion 66 that extends upward from the top plate rear portion 36b of the socket housing 21D and supports the middle in the front-rear direction of the movable portion 65 with a support shaft P extending in the left-right direction, and a part of the socket housing 21D Are integrally formed. A claw 67a is provided at the front end portion 67 of the movable portion 65 of the second locking means 60D so as to protrude downward. When the rear end portion 68 of the movable portion 65 is pressed downward, it can move like a seesaw. The portion 65 rotates about the support shaft P, and the tip end portion 67 including the claw 67a moves upward.

  Although the reason will be described later, as in the first example of the eighth embodiment shown in FIG. 25A, the claw 67a of the distal end portion 67 is engaged with the second locking portion 50D, that is, the movable portion 65 is horizontal. In the state, at least the lower portion 69a of the rear surface 69 of the claw 67a of the tip portion 67 is measured backward (clockwise in FIG. 25A) for the female connector 2D, and the angle β formed with the top plate front portion 36a of the socket housing 21D is An acute angle is preferred. As for the angle β, as in the second example shown in FIG. 25C, the entire rear surface 69 of the claw 67a of the distal end portion 67 may be measured backwards to form an acute angle with the top plate front portion 36a of the socket housing 21D. .

  In addition, as in the third example shown in FIG. 25D, it is also preferable that at least the lower part 69a of the rear surface 69 of the claw 67a of the tip end portion 67 is measured backward to make a right angle with the top plate front portion 36a of the socket housing 21D. Further, as in the fourth example shown in FIG. 25E, the entire rear surface 69 of the claw 67a of the distal end portion 67 may be measured in the backward direction and be perpendicular to the top plate front portion 36a of the socket housing 21D. However, the present invention is not limited thereto, and as in the fifth example shown in FIG. 26A, the rear surface 69 of the claw 67a of the distal end portion 67 is measured backward and forms an obtuse angle with the top plate front portion 36a of the socket housing 21D. You can also That is, the claw 67a of the distal end portion 67 of the second locking means 60D can be formed in a shape with a “barbed” with respect to the extraction of the female connector 2D from the male connector 1D.

  FIG. 24 is a side view showing a state in which the female connector 2D of the first example of the eighth embodiment shown in FIG. 23 is inserted and fitted into the male connector 1D of the first example of the seventh embodiment shown in FIG. . When the cylindrical bodies 24, 24 of the female connector 2D of FIG. 23 are inserted from the opening 5 (FIG. 22) of the base housing 3D of the male connector 1D, the tapered surfaces 31, 31 (FIG. 7) of the notch 23 become the partition walls 7. And the guide protrusions 29 and 29 on both sides engage with the guide grooves 12 and 12 (FIG. 11) and are guided to the correct fitting position, so that the male connector 1D is engaged. The contact pin portions 15 and 15 (FIG. 3) of both the pin contacts 4 and 4 enter the cylindrical bodies 24 and 24 through the insertion holes 27 and 27 (FIG. 7), and as shown in FIG. The socket parts 32 and 32 of 22 are fitted and electrically connected. When the distal ends of the cylindrical bodies 24, 24 of the female connector 2D come into contact with the rear side wall 6 of the male connector 1D and the fitting of both the connectors 1D, 2D is completed, the first locking means 28, 28 of the female connector 2D. Engages with the first locking portions 11, 11 of the male connector 1D, so that the female connector 2D is prevented from coming off from the male connector 1D mounted on the printed wiring board 43 (FIG. 24).

  When the cylindrical bodies 24, 24 of the female connector 2D of FIG. 23 are inserted from the opening 5 (FIG. 22) of the male connector 1D, the second locking means 60D of the female connector 2D is parallel to the above-described operation. The movable portion 65 is bent while being rotated and tilted about the support shaft P so that the distal end portion 67 moves upward, and the claw 67a of the distal end portion 67 advances while contacting the upper surface of the second locking portion 50D. As shown in FIG. 24, when the fitting of both connectors 1D and 2D is completed, the claw 67a of the distal end portion 67 gets over the second locking portion 50D, and the movable portion 65 becomes horizontal as before, so that the claw 67a Engages the rear surface 58 of the second locking portion 50D, and this also prevents the female connector 2D from coming off the male connector 1D.

  If the retaining is only the engagement between the first locking portions 11, 11 and the first locking means 28, 28 (FIG. 9) as in the prior art, the electric wire connected to the female connector 2D with respect to the male connector 1D When 45 is pulled strongly in the direction in which it is prevented from coming off (the left direction in FIG. 24), the effect of retaining it is not sufficient. However, according to any example of the male connector 1D of the seventh embodiment or the female connector 2D of the eighth embodiment, the first locking portions 11 and 11 (FIG. 9) and the second locking are used as a plurality of retaining mechanisms. Since the portion 50D or the first locking means 28, 28 (FIG. 9) and the second locking means 60D are provided, the effect of preventing the disconnection is improved, and the electric wire 45 connected to the female connector 2D is inadvertent. The female connector 2D will not come out of the male connector 1D.

  Now, as described above, in the male connector 1A of the first embodiment and the female connector 2A of the second embodiment shown in FIG. The bending of the arm portions 62 and 62 in the two locking means 60A is used. Similarly, in the male connector 1B of the third embodiment and the female connector 2B of the fourth embodiment shown in FIG. 13, the second locking means 60B of the female connector 2B is used for both preventing and releasing the release. Is used. Therefore, in these connectors 1A and 2A, 1B and 2B, if the stopper can be smoothly removed, the stopper can be normally released smoothly.

  On the other hand, in the male connector 1D of the seventh embodiment and the female connector 2D of the eighth embodiment shown in FIG. 24, when the retaining is performed, the movable portion 65 of the second locking means 60D of the female connector 2D is supported. Both the rotation (inclination) about the axis P and the bending with the support shaft P as a fixed end are used, but when releasing the stopper, by pressing the rear end portion 68 of the movable portion 65 downward, The claw 67a of the tip 67 is moved upward. That is, when releasing the stopper, only the rotation about the support shaft P of the movable portion 65 is used. Therefore, even if the stopper can be made smoothly, the stopper cannot be released smoothly as much. This point will be described in detail below.

  The combination of the male connector 1D of the first example of the seventh embodiment shown in FIG. 26A and the female connector 2D of the fifth example of the eighth embodiment will normally be described in a state where the fitting of both the connectors 1D and 2D has been completed. A play is provided so that the rear surface 58 of the second locking portion 50D does not contact the rear surface 69 of the claw 67a provided at the tip portion 67 of the second locking means 60D. However, when the female connector 2D is to be pulled out from the male connector 1D after the stopper is released, there is a tendency that there is no play as shown in FIG. 26B. To release the retaining member, it is necessary to rotate the movable part 65 around the support shaft P and move the claw 67a of the tip part 67 upward by pressing the rear end part 68 of the movable part 65 downward. However, as shown in FIG. 26B, when both the second locking portion 50D and the claw 67a of the tip end portion 67 of the second locking means 60D are shaped with a “barb”, The rear surface 58 of the second locking portion 50D becomes an obstacle, and it is difficult or impossible to rotate the claw 67a of the distal end portion 67 of the second locking means 60D around the support shaft P.

  As shown in FIG. 26C, the claw 67a of the tip 67 can be moved upward to some extent depending on the degree of play and play, but the lower end of the claw 67a is higher than the upper end of the second locking portion 50D. If it cannot be moved, the stopper cannot be released and the female connector 2D cannot be pulled out from the male connector 1D. As will be described later, in this state (the rear end portion 68 of the movable portion 65 is pressed downward, but the lower end of the claw 67a is lower than the upper end of the second locking portion 50D), the male connector 1D In order to pull out the female connector 2D, the rear surface 69 of the claw 67a of the front end portion 67 needs to have an acute angle γ with the top plate front portion 36a of the socket housing 21D across the space. The angle β (FIG. 26A, FIG. 26B) that was an obtuse angle in the horizontal state before the end portion 68 is pressed downward hardly becomes an acute angle γ by a slight rotation of the movable portion 65 by the pressing. It is. Accordingly, it is not very preferable to combine the male connector 1D of the first example of the seventh embodiment and the female connector 2D of the fifth example of the eighth embodiment into a connector set.

  A preferred embodiment of the connector set in the present invention includes a combination of the first example male connector 1D of the seventh embodiment and the first example female connector 2D of the eighth embodiment shown in FIG. 25A. In the connector sets 1D and 2D, only the second locking portion 50D has a “barbed” shape, and the claws provided on the rear surface 58 of the second locking portion 50D and the distal end portion 67 of the second locking means 60D. Even in a state where there is no play in contact with the rear surface 69 of 67a, by pressing the rear end portion 68 of the movable portion 65 downward, the claw 67a of the distal end portion 67 of the second locking means 60D is supported. When rotating around the axis P, the rear surface 58 of the second locking portion 50D does not become an obstacle, and it is easy to move the lower end of the claw 67a upward from the upper end of the second locking portion 50D. And the female connector 2D can be pulled out from the male connector 1D.

  Even if the lower end of the claw 67a cannot be moved upward from the upper end of the second locking portion 50D as shown in FIG. 25F, the rear end portion 68 of the movable portion 65 is pressed downward. Then, since at least the lower part 69a of the rear surface 69 of the claw 67a of the tip 67 has an acute angle γ formed with the top plate front part 36a of the socket housing 21D across the space, and has a shape without a “barbed”, it remains as it is. When the female connector 2D is pulled with respect to the male connector 1D, the rear surface lower portion 69a of the claw 67 is in contact with the upper rear end of the second locking portion 50D, and the claw 67a is moved upward and rearward. The lower end of the claw 67a rides on the upper surface of the second locking portion 50D and is disengaged. That is, the retainer is released and the female connector 2D can be pulled out from the male connector 1D. Another example of such a preferred connector set embodiment is a combination of the male connector 1D and the female connector 2D shown in FIGS. 25B to 25E.

  Another embodiment of a preferred connector set according to the present invention is a combination of the third example male connector 1D of the seventh embodiment shown in FIG. 27A and the fifth example female connector 2D of the eighth embodiment. . In the connector sets 1D and 2D, only the claw 67a of the distal end portion 67 of the second locking means 60D has a “barbed” shape, and the rear surface 58 of the second locking portion 50D and the distal end of the second locking means 60D. Even in a state where there is no play where the rear surface 69 of the claw 67a provided on the portion 67 is in contact, the front end portion of the second locking means 60D is pressed by pressing the rear end portion 68 of the movable portion 65 downward. When the claw 67a of 67 is rotated around the support shaft P, the rear surface 58 of the second locking portion 50D does not become an obstacle, and the lower end of the claw 67a is moved above the upper end of the second locking portion 50D. It is easy to release the stopper, and the female connector 2D can be pulled out from the male connector 1D.

  Although not shown, even if the lower end of the claw 67a cannot be moved above the upper end of the second locking portion 50D, at least the upper part 58a of the rear surface 58 of the second locking portion 50D sandwiches the space. Since the angle α formed with the top plate front portion 36a of the base housing 21D is an obtuse angle and does not have a “bare”, when the female connector 2D is pulled with respect to the male connector 1D as it is, In the reverse operation, the lower end of the rear surface 69 of the claw 67 is in contact with the upper rear surface 58a of the second locking portion 50D, the claw 67a moves up and rearward, and the lower end of the claw 67a rides on the upper surface of the second locking portion 50D. To disengage. That is, the retainer is released and the female connector 2D can be pulled out from the male connector 1D. Another example of such a preferred connector set embodiment is a combination of a male connector 1D and a female connector 2D shown in FIG. 27B.
