However, the conventional connector disclosed in Patent Document 1 has the following problems.
That is, if an excessive load is applied to the lock portion with the insert inserted in the housing, the insert may fall off the housing. That is, if the connector falls or vibrates vigorously with the insert inserted in the housing, an excessive load is applied to the lock portion. When an excessive load is applied to the lock portion, the lock portion is deformed in a direction to be crushed. The free end of the lock spring, that is, the free end of the lock portion is locked by a stopper to prevent the free end of the lock portion from being displaced. However, it is not supported by any member between the fixed end of the lock spring and the free end of the lock portion. For this reason, it can be easily deformed between the fixed end of the lock spring and the free end of the lock portion, and when an excessive load is applied, the lock portion is deformed in a direction to be crushed.

  Accordingly, the present invention has been made in view of this problem, and an object of the present invention is to provide an ejector mechanism for discharging the insert inserted into the housing, and the insert in a state where the insert is inserted into the housing. It is an object of the present invention to provide a connector having a lock mechanism having a lock spring for locking and having an improved holding force of the lock spring.

In this connector, it is preferable that the second convex portion is provided in the vicinity of the lock portion opposite to the free end with the lock portion interposed therebetween.

In this connector, the insert is preferably a card tray on which a card is mounted.
Further, in this connector, the insert may be a single card.
Furthermore, the insert may be a single card tray.

  According to the connector of the present invention, the pressing member is provided with the first convex portion that protrudes toward the lock spring, and protrudes toward the pressing member between the fixed end and the free end of the lock spring. A second convex portion is provided. Then, when the insertion body is locked to the locked part by the lock part, the free end of the lock spring comes into contact with the pressing member, and the second convex part of the lock spring comes into contact with the first convex part of the pressing member. For this reason, when the lock part of the lock spring locks the locked part of the insert, the lock spring is supported by the pressing member by the two points of the free end and the second convex part. For this reason, it becomes difficult to deform | transform from the fixed end of a lock spring to a free end rather than being supported at one point. Thereby, when an excessive load is applied to the lock portion, it is possible to reduce a possibility that the lock portion is deformed in a direction in which the lock portion is crushed, and to improve the holding force of the lock spring.

  Further, when the insert is locked to the locked part by the lock part, the free end of the lock spring comes into contact with the pressing member, and the second convex part of the lock spring comes into contact with the first convex part of the pressing member. For this reason, the contact of the pressing member with the lock spring is achieved by the convex portions of the pressing member and the free end of the lock spring, and the first convex portion of the pressing member and the second convex portion of the lock spring. Thereby, when a press member slides, those contact states can be cancelled | released easily and a press member can be slid easily.

  As shown in FIGS. 7, 8, and 11, an opening 41 d that is notched upward from the lower edge of the pressing member 41 is formed in the vicinity of the other end 41 b of the pressing member 41. . The opening 41d allows the free end 51d of the first lock spring 51 to pass when the lock 51b of the first lock spring 51 does not lock the second recess 65b when the card tray 60 is inserted and ejected. .

Next, the operation of the eject mechanism 40 and the operation of the lock mechanism 50 will be described in detail with reference to FIGS. 5, 8 </ b> A, 8 </ b> B, 9, 10, and 11.
First, in a state where the card tray 60 on which the card C is mounted in the housing 10 is not inserted, as shown in FIG. 5, the pressing member 41 of the ejection mechanism 40 is located at the rearmost position, and the other end 42b of the ejection arm 42. Is located in the tray insertion space 15. Further, as shown in FIG. 5A, the lock portion 51 b of the first lock spring 51 protrudes into the tray insertion space 15 when the card tray 60 is not inserted into the tray insertion space 15. . The lock portion 52 b of the second lock spring 52 protrudes into the tray insertion space 15 when the card tray 60 is not inserted into the card insertion space 15.

  8A and 8B, when the card tray 60 on which the card C is mounted is inserted into the tray insertion space 15, the tip of the card tray 60 is the other end of the eject arm 42. 42b abuts. When the card tray 60 is inserted into the tray insertion space 15, the lock portion 51 b of the first lock spring 51 is temporarily displaced outward in the width direction along the right edge of the card tray 60. Further, the lock portion 52 b of the second lock spring 52 is also temporarily displaced outward in the width direction along the left edge of the card tray 60. Then, before the card tray 60 contacts the other end 42b of the eject arm 42, the lock portion 51b of the first lock spring 51 is displaced inward in the width direction along the right edge of the card tray 60, and the card tray 60 first recesses 65a. The lock portion 52 b of the second lock spring 52 is also displaced inward in the width direction along the left side edge of the card tray 60 and enters the third recess 66 a of the card tray 60. When the insertion of the card tray 60 proceeds and the card tray 60 is in contact with the other end 42b of the eject arm 42, the lock portion 51b of the first lock spring 51 is positioned on the front side of the first recess 65a. It is displaced outward in the width direction by the inclined surface. Moreover, the lock part 52b of the 2nd lock spring 52 is displaced to the width direction outer side by the inclined surface located in the front side of the 3rd recessed part 66a.

Here, in a state where the lock portion 51b of the first lock spring 51 is displaced outward in the width direction, as shown in FIGS. 7 and 8A and 8B, the free end 51d of the first lock spring 51 is It passes through an opening 41d formed in the pressing member 41.
Further, when the insertion of the card tray 60 proceeds, the lock portion 51b of the first lock spring 51 is further displaced outward in the width direction and comes out of the first recess 65a. Further, the lock portion 52b of the second lock spring 52 is further displaced outward in the width direction and comes out of the third recess 66a. When the lock 51b exits the first recess 65a, the lock 51b moves on the inclined surface located on the front side of the first recess 65a, so that the lock 51b can easily exit the first recess 65a. Further, when the lock 52b exits the third recess 66a, it moves on the inclined surface located on the front side of the third recess 66a, so that the lock 52b can easily exit the third recess 66a. Also at this time, the free end 51 d of the first lock spring 51 passes through the opening 41 d formed in the pressing member 41. At this time, the front end of the card tray 60 presses the other end 42b of the eject arm 42, and the eject arm 42 rotates in the clockwise direction. As a result, the pressing member 41 slides forward (in the tray discharge direction) by being pressed by the one end 42a of the eject arm 42.

When the insertion of the card tray 60 is completed, as shown in FIG. 9A, the lock portion 51b of the first lock spring 51 is displaced inward in the width direction, returns to the original state, and enters the second recess 65b. . As a result, the card tray 60 is locked. Further, the lock portion 52b of the second lock spring 52 also enters the fourth recess 66b to lock the card tray 60.
Further, as shown in FIG. 9, when the insertion of the card tray 60 is completed, the tip of the card tray 60 presses the other end 42b of the eject arm 42, and the eject arm 42 further rotates clockwise. Accordingly, the pressing member 41 is further slid forward (in the tray discharge direction) by being pressed by the one end 42a of the eject arm 42. Then, the free end 51 d of the first lock spring 51 comes into contact with the side surface of the pressing member 41. At the same time, the second convex portion 51 e of the first lock spring 51 comes into contact with the first convex portion 41 c of the pressing member 41.

  Thus, when the lock part 51b of the 1st lock spring 51 locks the 2nd recessed part 65b of the card | curd tray 60, the 1st lock spring 51 is a pressing member by two points, the free end 51d and the 2nd convex part 51e. 41 is supported. For this reason, it becomes difficult to deform | transform from the fixed end 51c of the 1st lock spring 51 to the free end 51d rather than being supported by one point. Thereby, when an excessive load is applied to the lock part 51b, it is possible to reduce the possibility that the lock part 51b is deformed in a direction to be crushed. Accordingly, the holding force of the first lock spring 51 can be improved.

The second protrusion 51e of the first lock spring 51 is provided on the opposite side of the free end 51d across the lock 51b and in the vicinity of the lock 51b. For this reason, since the lock part 51b is supported by the 2nd convex part 51e, it can reduce a possibility that the lock part 51b may deform | transform in the direction which collapses.
Next, when the card tray 60 is ejected from the state where the insertion of the card tray 60 is completed, the card tray 60 is ejected using the pins 70 as shown in FIG. More specifically, the pin 70 is inserted into the pin through hole 64 of the card tray 60 and brought into contact with the other end 41 b of the pressing member 41 from the front of the housing 10.

  Then, from the state in which the pin 70 is in contact with the other end 41 b of the pressing member 41, the pin 70 is pressed backward (in the tray insertion direction indicated by the arrow X). Then, the pressing member 41 slides backward, one end 41a of the pressing member 41 presses one end 42a of the eject arm 42, and the eject arm 42 rotates counterclockwise. As a result, the card tray 70 is pressed forward by the other end 42b of the eject arm 42 and moves in the forward direction (tray ejection direction indicated by the arrow Y).

  Here, before the pressing member 41 slides backward, the free end 51d of the first lock spring 51 abuts against the side surface of the pressing member 41, and the second convex portion 51e of the first lock spring 51 presses. The first protrusion 41c of the member 41 is in contact with the first protrusion 41c. Therefore, the contact of the pressing member 41 with the first lock spring 51 is such that the side surface of the pressing member 41, the free end 51 d of the first lock spring 51, the first protrusion 41 c of the pressing member 41, and the first lock spring 51. This is achieved by convex protrusions with the two convex portions 51e. Thereby, when the pressing member 41 slides backward, those contact states can be easily released, and the pressing member 41 can be easily slid backward. When the pressing member 41 slides backward, the free end 51 d of the first lock spring 51 is positioned on the side of the opening 41 d of the pressing member 41.

  When the card tray 60 moves in the forward direction (the tray discharge direction indicated by the arrow Y), the lock portion 51 b of the first lock spring 51 comes out of the second recess 65 b of the card tray 60. Further, the lock portion 52 b of the second lock spring 52 also comes out of the fourth recess 66 b of the card tray 60. As a result, the lock of the card tray 60 by the lock mechanism 50 is released. Then, the lock portion 51 b of the first lock spring 51 is displaced outward in the width direction along the right edge of the card tray 60. At this time, the free end 51 d of the first lock spring 51 passes through the opening 41 d of the pressing member 41.

Thus, since the free end 51d of the first lock spring 51 passes through the opening 41d of the pressing member 41, the free end 51d of the first lock spring 51 does not interfere with the sliding operation of the pressing member 41.
When the pin 70 is further pressed rearward, the pressing member 41 further slides backward, one end 41a of the pressing member 41 presses one end 42a of the eject arm 42, and the eject arm 42 further rotates counterclockwise. . As a result, the card tray 60 moves further forward (in the tray ejection direction) by being pressed by the other end 42b of the eject arm 42, and the ejection of the card tray 60 is completed as shown in FIG. At this time, the lock portion 51 b of the first lock member 51 is located on the inclined surface located on the front side of the first recess 65 a of the card tray 60 and is displaced inward in the width direction. The lock portion 52b of the second lock member 52 is also located on the inclined surface located on the front side of the third recess 66a of the card tray 60 and is displaced inward in the width direction. At this time, the free end 51 d of the lock portion 51 b of the first lock member 51 remains passing through the opening 41 d of the pressing member 41.

  Then, the worker only has to pull out the card tray 60 on which the card C is mounted from the state shown in FIG. When the card tray 60 is pulled out, the first lock spring 51 returns to the initial state shown in FIG. Similarly, the second lock spring 52 also returns to the initial state. At this time, the lock portion 51b of the first lock spring 51 is extracted from the first recess 65a, but passes through the inclined surface located on the rear side of the first recess 65a, so that the lock portion 51 can be easily removed from the first recess 65a. Can be extracted.

As mentioned above, although embodiment of this invention has been described, this invention is not limited to this, A various change and improvement can be performed.
For example, the card tray 60 on which the card C is mounted has been described as an example of the insert inserted into the connector 1, but the card C alone or the card tray 60 alone may be used. . When the card C alone is used as an insertion body, it is necessary to form a locked portion to be locked by the lock portion 51b of the first lock spring 51 on the side edge of the card C.

The second convex portion 51e of the first lock spring 51 is provided in the vicinity of the lock portion 51b opposite to the free end 51d with the lock portion 51b interposed between the fixed end 51c and the free end 51d. It is not always necessary.
Furthermore, at least one of the first convex portion 41c and the second convex portion 51e may be an emboss or the like formed to protrude from the metal plate instead of protruding in a curved state.
