Japanese Patent No. 889 proposes a mechanism for removing a card from a unit. Further, Japanese Patent Application Laid-Open No. 2-27671 proposes a card having a daughter board (terminal block).
A card having such a daughter board has a large number of connection pins, and as a result, a large pulling force is required when pulling it out of the connector, so that it is difficult to pull it out with bare hands.
Therefore, a removal mechanism called a card plaque that uses the lever action is adopted.

に予想外の障害をもたらす可能性があった。However, the daughter board may be removed from the card in some cases, and in this case as well, the removal force is similarly increased. Then, when only the daughter board is replaced, if the card is pulled out with bare hands, the entire card may be accidentally detached from the connector, which may cause an unexpected failure in the entire system.

However, such a two-stage mounting causes a time hindrance to the card replacement work that requires quick and reliable work, and reduces workability. There was a problem of becoming. The present invention solves such a problem, and an object of the present invention is to provide a small card removal device that prevents erroneous removal when the daughter board is removed from the card.

で、拘束穴３４に緩挿される。FIG. 2 is a block diagram for explaining the details of the extraction unit 40. As for the basic shape of the extraction portion 40, one of the rod-shaped connecting portions 47 is the lever portion 42 and the other is the housing contact portion 43, and the protruding portion 45 projects in a T-shape. The wing-shaped leg portion 46 attached to the connecting portion 47 is provided with the shaft support portion 41 substantially at the center of the wing and the claw portion 44 near the tip of the wing. The shaft support 41 rotatably supports the removal unit 40 with respect to the card 20, and has a shape that engages with a through hole when the card 20 is provided, for example. The lever portion 42 serves as an attachment point when the card 20 is detached from the housing 10, and the distance from the tip of the lever portion 42 to the connecting portion 47 is H 0 . The housing contact portion 43 is located on the opposite side of the lever 42 with the projected position of the shaft support portion 41 of the connection portion 47 interposed therebetween, and has a smooth cylindrical end. The claw portion 44 is provided in a region closer to the housing contact portion 43 than the shaft support portion 41 of the leg portion 46, and is engaged with the engagement hole 13. The protruding portion 45 has a connecting portion 47.
The height H 1 of the leg portion 46 projects from the side opposite to the mounting surface of the leg portion 46 and is loosely inserted into the restraining hole 34.

も伝達される。The operation of the thus constructed apparatus will be described below. When the card 20 is housed in the housing 10, the claw portion 44 is engaged with the locking hole 13. If the daughter board 30 is attached to the card 20,
The protrusion 45 is loosely inserted into the restraint hole 34. In this state, when detaching the daughter board 30 from the card 20, as shown in FIG.
Add force to move in the direction. Then the connector 32
This force F is also transmitted to the card 20 by fitting the connector 22 with the connector 22.

係を維持する。As shown in FIG. 2, the force F applied to the card 20 is transmitted to the connector for connection with the housing 10 and also acts as a component force F1 on the shaft support 41. As a result, assuming that the distance between the fulcrum A of the claw portion 44 and the shaft support portion 41 is l A , the moment M1 (= F1.
l A ) acts. As a result, the ejecting portion 40 rotates, but since the protrusion 45 is loosely inserted in the restraint hole 34, the protrusion 45 is slightly rotated and the reaction force R B from the card side wall surface 33 around the restraint hole 34. Receive. Now, when the distance between the point B and the claw portion 44 of the reaction force R B and l B, the moment around the claw portion 44 M2 (= R B · l B) is generated, moment balance. Then, the claw portion 44 is constrained in a posture that maintains the engagement with the locking hole 13. Then, the reaction force RA is generated in the claw portion 44, and the force F substantially applied to the card 20 is generated.
To face. Therefore, the card 20 maintains the engagement relationship with the housing 10.

At this time, when the lever portion 42 is pulled in the direction of the arrow C, the housing contact portion 43 comes into contact with the stopper surface 14 to serve as a fulcrum, and a force expanded by the lever action is generated in the shaft support portion 41. Then, by the force of the shaft support portion 41, the card 2
0 is released from the fitting state with the housing 10.

In the figure, the leg portions 46 are a pair and are held by the connecting portion 47 in a facing posture. Here, the shaft support portion 41 having the convex base portion 41a and the inclined surface portion 41b is provided on one leg portion 46a, and the other leg portion 46b is flat. The convex base portion 41 a is the connecting portion 47 of the shaft support portion 41.
The semi-circular column is projected toward the other leg 46b, and the other leg 46 at the tip is located.
The distance from b is t 1 . The inclined surface portion 41b is located at a position far from the connecting portion 47 of the shaft support portion 41, and is inclined so that the distance from the convex base portion 41a to the other leg portion 46b increases to t 2 . The opening portion 41c is a window provided between the shaft support portion 41 and the connecting portion 47, and is formed by the extraction portion 4
The weight of 0 is lightened and the bending rigidity of the leg portion 46 is reduced to facilitate the attachment to the card 20.
