However, the connector shown in the prior patent document 1 has the following problems.

That is, when an excessive load is applied to the locking portion when the insertion body is inserted into the chassis, the insertion body is detached from the chassis. In other words, when the insert body is inserted into the frame state, for example, when the connector is dropped or vibrated violently, 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 the direction of crushing. The free end of the locking spring, i.e. the free end of the locking portion, engages the stop to prevent the free end of the locking portion from being displaced. However, there is no support between any of the members from the fixed end of the locking spring to the free end of the locking portion. Therefore, it is easily deformed from the fixed end of the lock spring to the free end of the lock portion, and when an excessive load is applied, the lock portion is deformed in the direction of crushing.

Accordingly, the present invention has been made in view of the problem, and an object thereof is to provide a connector comprising: an ejector mechanism for discharging an insertion body inserted into a frame; and a locking mechanism having a insertion body in the insertion body The locking spring of the insert body is locked in the frame state, and the holding force of the lock spring is increased.

In order to achieve the above object, a connector of the present invention has a frame for inserting an insert body, a plurality of contacts fixed to the frame, and an ejector mechanism. And a locking mechanism for locking the insertion body of the insertion body in a state in which the insertion body is inserted, wherein the ejector mechanism includes: an exiting arm; a rotatably supported shaft in the frame, and the insertion body inserted into the frame; and a pressing member that drives the exit arm at one end by pressing from the outside, the locking spring of the locking mechanism being fixed to the foregoing The frame extends in a cantilever beam shape and has a locking portion near the free end thereof, which is locked in a locked portion of the insertion body in a state in which the insertion body is inserted, and the pressing member is provided to protrude toward the lock spring. a first convex portion, and a second convex portion that protrudes toward the pressing member between the fixed end and the free end of the lock spring, and when the locked portion is locked by the locking portion, the free end of the lock spring abuts The pressing member is connected to the pressing member, and the second convex portion of the locking spring abuts against the first convex portion of the pressing member.

Further, in the connector, it is preferable that the pressing member is formed with an opening that allows the free end of the lock spring to pass when the lock portion is inserted into the lock portion and the lock portion does not lock the lock portion.

Further, in the connector, the second convex portion is preferably provided in the vicinity of the lock portion on the side opposite to the free end with the lock portion interposed therebetween.

Further, in the connector, the insertion body is preferably a bracket for carrying a card.

Further, in the connector, the insertion body may be a card unit.

Furthermore, the insert body may be a single bracket for a card.

When the connector of the present invention is used, a first convex portion that protrudes toward the lock spring is provided in the pressing member, and a direction is pressed between the fixed end and the free end of the lock spring. a second protrusion protruding from the member. Then, when the locked portion of the insertion body is locked by the locking portion, the free end of the lock spring abuts against the pressing member, and the second convex portion of the lock spring abuts against the first convex portion of the pressing member. Therefore, when the locking portion of the lock spring locks the locked portion of the insertion body, the lock spring is supported by the pressing member by the two points of the free end and the second convex portion. Therefore, it is less likely to be deformed than when the lock spring is supported at a point from the fixed end to the free end. Thereby, it is possible to reduce the possibility that the locking portion is deformed in the crushing direction when an excessive load is applied to the lock portion, and the holding force of the lock spring can be improved.

Further, when the locked portion of the insertion body is locked by the locking portion, the free end of the lock spring abuts against the pressing member, and the second convex portion of the lock spring abuts against the first convex portion of the pressing member. Therefore, the abutment of the pressing member to the lock spring is achieved by the respective ends of the pressing member and the free end of the lock spring, the first convex portion of the pressing member, and the second convex portion of the lock spring. Thereby, when the pressing member slides, the abutting state can be easily released, and the pressing member can be easily slid.

Next, the operation of the ejector mechanism 40 and the operation of the lock mechanism 50 will be described in detail with reference to the fifth and eighth aspects (A), (B), ninth, tenth, and eleventh views.

First, in a state in which the card holder 60 for carrying the card C is not inserted into the chassis 10, as shown in the fifth figure, the pressing member 41 of the ejector mechanism 40 is located at the last side, and the other end 42b of the exiting arm 42 is located. The bracket is inserted into the space 15. Further, as shown in FIG. 5(A), the locking portion 51b of the first lock spring 51 protrudes in the bracket insertion space 15 in a state where the card bracket 60 is not inserted into the bracket insertion space 15. The locking portion 52b of the second lock spring 52 protrudes in the bracket insertion space 15 in a state where the card bracket 60 is not inserted into the bracket insertion space 15.

Then, as shown in the eighth (A) and (B), when the card holder 60 on which the card C is mounted is inserted into the tray insertion space 15, the front end of the card holder 60 abuts on the other end of the exit arm 42. 42b. At the beginning of insertion of the card holder 60 into the tray insertion space 15, the lock portion 51b of the first lock spring 51 temporarily changes outward in the width direction along the right edge of the card holder 60. Further, the lock portion 52b of the second lock spring 52 is also temporarily displaced outward in the width direction along the left side edge of the card bracket 60. Then, before the card bracket 60 abuts against the other end 42b of the exit arm 42, the locking portion 51b of the first lock spring 51 is located on the inner side in the width direction along the right edge of the card bracket 60, and enters the card tray. The first recess 65a of the frame 60. Further, the lock portion 52b of the second lock spring 52 also enters the inner side in the width direction along the left side edge of the card bracket 60, and enters the third recessed portion 66a of the card bracket 60. Then, the card holder 60 is inserted, and in a state where the card holder 60 abuts against the other end 42b of the exit arm 42, the locking portion 51b of the first lock spring 51 is located on the front side of the first recess 65a. The change is located outside the width direction. Further, the locking portion 52b of the second lock spring 52 is displaced outward in the width direction by the inclined surface on the front side of the third recess 66a.

Here, in a state where the locking portion 51b of the first lock spring 51 is displaced outward in the width direction, as shown in the seventh and eighth drawings (A) and (B), the free end 51d of the first lock spring 51 passes. The opening 41d is formed in the pressing member 41.

Further, when the card holder 60 is inserted, the lock portion 51b of the first lock spring 51 is further displaced outward in the width direction and extracted from the first recess portion 65a. Further, the locking portion 52b of the second lock spring 52 is further displaced outward in the width direction and extracted from the third recess 66a. When the lock portion 51b is withdrawn from the first recessed portion 65a, the lock portion 51b can be easily withdrawn from the first recessed portion 65a by moving on the inclined surface on the front side of the first recessed portion 65a. Further, when the locking portion 52b is withdrawn from the third recessed portion 66a, the locking portion 52b can be easily removed from the inclined surface on the front side of the third recessed portion 66a. The third recess 66a is drawn out. At this time, the free end 51d of the first lock spring 51 also passes through the opening portion 41d formed in the pressing member 41. Further, at this time, the front end of the card holder 60 presses the other end 42b of the exit arm 42, and the exit arm 42 rotates in the clockwise direction. Thereby, the pressing member 41 is pressed against the one end 42a of the exit arm 42, and the pressing member 41 slides in the front direction (the tray discharge direction).

Then, when the insertion of the card holder 60 is completed, as shown in the ninth diagram (A), the locking portion 51b of the first lock spring 51 is displaced inward in the width direction, and returns to the original state to enter the second recess 65b. Thereby, the card holder 60 is locked. Further, the locking portion 52b of the second lock spring 52 also enters the fourth recess 66b to lock the card bracket 60.

Further, as shown in the ninth figure, when the insertion of the card holder 60 is completed, the front end of the card holder 60 is pressed against the other end 42b of the exit arm 42, and the exit arm 42 is further rotated in the clockwise direction. Thereby, the pressing member 41 is further slid in the front direction (the tray discharge direction) by being pressed against one end 42a of the exit arm 42. Then, the free end 51d of the first lock spring 51 abuts against the side surface of the pressing member 41. Further, at the same time, the second convex portion 51e of the first lock spring 51 abuts against the first convex portion 41c of the pressing member 41.

When the locking portion 51b of the first lock spring 51 locks the second recessed portion 65b of the card bracket 60, the first lock spring 51 is supported by the pressing member 41 at two points by the free end 51d and the second convex portion 51e. Therefore, it is less likely to be deformed than when it is supported by a point from the fixed end 51c of the first lock spring 51 to the free end 51d. Thereby, it is possible to reduce the possibility that the lock portion 51b is deformed in the crushing direction when an excessive load is applied to the lock portion 51b. Therefore, the holding force of the first lock spring 51 can be increased.

Further, the second convex portion 51e of the first lock spring 51 is provided on the opposite side of the free end 51d from the lock portion 51b and in the vicinity of the lock portion 51b. Therefore, since the lock portion 51b is supported by the second convex portion 51e, the possibility that the lock portion 51b is deformed toward the crushing direction can be further reduced.

Next, when the card holder 60 is inserted from the state in which the card holder 60 is inserted, as shown in the tenth figure The card holder 60 is ejected using the latch 70. Specifically, the plug 70 is inserted into the pin through hole 64 of the card holder 60, and is abutted against the other end 41b of the pressing member 41 from the front of the chassis 10.

Then, the plug 70 is pressed in the rear direction (the bracket insertion direction indicated by the arrow X) from the state in which the latch 70 abuts against the other end 41b of the pressing member 41. As described above, the pressing member 41 slides in the rear direction, and one end 41a of the pressing member 41 presses the one end 42a of the ejecting arm 42, and the ejecting arm 42 rotates in the counterclockwise direction. Thereby, the card holder 60 is pressed against the other end 42b of the exit arm 42 and moved in the front direction (the direction in which the arrow Y indicates the tray discharge direction).

Here, before the pressing member 41 slides in the rear direction, the free end 51d of the first locking spring 51 abuts against the side surface of the pressing member 41, and further, the second convex portion 51e of the first locking spring 51 abuts against the pressing member 41. The first convex portion 41c. Therefore, the pressing of the pressing member 41 against the first locking spring 51 is performed by the side of the pressing member 41 and the free end 51d of the first locking spring 51, the first convex portion 41c of the pressing member 41, and the second convex portion of the first locking spring 51. Each of the projections of the portion 51e is achieved. Thereby, when the pressing member 41 slides in the backward direction, the contact state can be easily released, and the pressing member 41 can be easily slid in the backward direction. Then, when the pressing member 41 is slid in the rear direction, the free end 51d of the first lock spring 51 is located at the side of the opening portion 41d of the pressing member 41.

Then, when the card holder 60 is moved in the front direction (the direction in which the arrow is indicated by the arrow Y), the locking portion 51b of the first lock spring 51 comes out from the second recess 65b of the card holder 60. Further, the locking portion 52b of the second lock spring 52 also comes out from the fourth recess 66b of the card bracket 60. Thereby, the lock mechanism 50 locks the card holder 60. Then, the lock portion 51b of the first lock spring 51 is displaced outward in the width direction along the right edge of the card bracket 60. At this time, the free end 51d of the first lock spring 51 passes through the opening portion 41d of the pressing member 41.

Thus, since the free end 51d of the first lock spring 51 passes through the pressing member 41 Since the opening portion 41d is opened, the free end 51d of the first lock spring 51 does not cause an obstacle when the pressing member 41 slides.

Further, when the latch 70 is pressed in the rear direction, the pressing member 41 is further slid in the rear direction, and one end 41a of the pressing member 41 is pressed against the one end 42a of the ejecting arm 42, and the ejecting arm 42 is further rotated in the counterclockwise direction. Thereby, the card holder 60 is pressed against the other end 42b of the exit arm 42 and further moved in the front direction (the tray discharge direction), and as shown in the eleventh figure, the discharge of the card holder 60 is completed. At this time, the lock portion 51b of the first lock spring 51 is located on the inclined surface provided on the front side of the first recessed portion 65a of the card bracket 60, and is located on the inner side in the width direction. Further, the locking portion 52b of the second lock spring 52 is also located on the inclined surface provided on the front side of the third recessed portion 66a of the card bracket 60, and is located on the inner side in the width direction. At this time, the free end 51d of the locking portion 51b of the first lock spring 51 has passed through the opening portion 41d of the pressing member 41.

Then, the operator only needs to pull out the card holder 60 on which the card C is mounted, as shown in the eleventh figure. When the card holder 60 is pulled out, the first lock spring 51 returns to the initial state shown in the fifth figure. Further, similarly, the second lock spring 52 also returns to the initial state. At this time, although the locking portion 51b of the first lock spring 51 is pulled out from the first recessed portion 65a, the first lock spring 51 can be easily removed from the first recessed portion 65a by passing the inclined surface on the rear side of the first recessed portion 65a. Pull out.

The embodiment of the present invention has been described above, but the present invention is not limited thereto, and various modifications and improvements can be made.

For example, the insertion body of the connector 1 is exemplified by the card holder 60 on which the card C is mounted. However, the card C may be used alone or the card holder 60 may be used alone. In the case where the card C alone is used as the insert body, it is necessary to form the locked portion that locks the locking portion 51b of the first lock spring 51 to The side edge of the card C.

Further, when the second convex portion 51e of the first lock spring 51 is between the fixed end 51c and the free end 51d, it is not required to be provided in the vicinity of the lock portion 51b on the side opposite to the free end 51d with the lock portion 51b interposed therebetween.

In addition, at least one of the first convex portion 41c and the second convex portion 51e may be formed to protrude from a projection of a metal plate or the like instead of protruding in a curved state.
