Embodiment 1 FIG.
In general, memory cards such as SD cards and card members including FFC (flexible flat board) and FPC (flexible printed circuit board) are inserted and connected to dedicated connectors to exchange signals and information. It has come to be.

  For example, in a car navigation device, a card member such as an SD card in which map data is stored is inserted into a connector, and that part is closed with a cover so that it cannot be seen from the outside, or other parts are mounted in front of it Then, it may be shipped as a product after being closed with a cover or the like.

  At this time, the card member may be closed with a cover or the like without noticing that the card member is not completely inserted into the connector. In such a case, the card member is not inserted in the inspection at the time of shipment. It is necessary to remove the cover, remove other parts mounted in front of the connector, reinsert the card member, reattach the part, and close it with the cover. There was a problem of inefficiency.

Therefore, in the first embodiment of the present invention, the insertion position of the card member can be easily recognized by confirming the drawing amount (projection amount) of the sheet member mounted on the connector.
FIG. 1 is a perspective view showing a state before insertion when the card member 1 is inserted into the connector 2 in the first embodiment.

As shown in FIG. 1, the connector 2 according to the first embodiment includes a housing that has a card insertion slot 21 at one end surface and that accommodates the card member 1 inserted through the card insertion slot 21. The opening 22 formed in the surface (upper surface in FIG. 1) along the insertion direction of the card member 1 and the sheet member 3 are provided.
One end of the sheet member 3 is fixed to the side of the housing of the connector 2 where the opening 22 is formed (see FIG. 5), and the other end is drawn out of the housing of the connector 2 from the opening 22. Yes. That is, the other end side of the sheet member 3 protrudes outside the connector 2 and can be visually recognized.

FIG. 2 is a perspective view showing a state in which the card member 1 is completely inserted into the connector 2 in the first embodiment.
When the card member 1 is inserted from the card insertion slot 21 of the connector 2 from the state shown in FIG. 1, the sheet member 3 is brought into contact with the card member 1 and drawn into the housing of the connector 2, and is shown in FIG. As described above, the amount of drawing (the amount of protrusion) of the sheet member 3 visible from the outside of the connector 2 is small (short).

  That is, when the card member 1 is inserted into the connector 2, the drawing amount (protrusion amount) of the sheet member 3 from the opening 22 of the connector 2 changes according to the insertion amount of the card member 1. Then, the insertion position of the card member 1 into the connector 2 can be confirmed by the drawing amount (projection amount) of the sheet member 3.

  At this time, in order to clarify how much the drawing amount (projection amount) of the sheet member 3 is small (short), the card member 1 is completely inserted into the connector 2. A mark 4 (see FIG. 3) is provided as an index of the amount of drawing from the opening 22.

  FIG. 3 is a plan view (viewed from above) showing a state in which the card member 1 is not inserted into the connector 2 in Embodiment 1 (the insertion is not completed). That is, when the connector 2 shown in FIG. 1 is viewed from above, it looks as shown in FIG. Then, since the mark 4 on the surface (upper surface) of the sheet member 3 is visible from the outside, it is understood that the card member 1 is incompletely inserted into the connector 2.

  FIG. 4 is a plan view (viewed from above) showing a state in which the card member 1 is completely inserted into the connector 2 in the first embodiment. That is, when the connector 2 shown in FIG. 2 is viewed from above, it looks as shown in FIG. Then, the sheet member 3 is pulled into the housing of the connector 2, and the mark 4 on the surface (upper surface) of the sheet member 3 enters the inside of the housing of the connector 2 so that it cannot be visually recognized. It can be seen that the insertion into the connector 2 is completed.

FIG. 5 is a schematic cross-sectional view showing the structure of the connector 2 in the first embodiment.
As shown in FIG. 5, one end of the sheet member 3 is fixed to the surface side (upper surface side) in which the opening of the housing of the connector 2 is formed, and the other end of the sheet member 3 while being bent. The side is drawn out of the housing from the opening 22.

  Further, the mark 4 serving as an index of the amount of extraction (projection amount) from the opening 22 is in any form such as a tape-like thing attached to the surface (upper surface) of the sheet member 3 or a printed line. It may be.

  Further, as shown in FIG. 5, a rubber sheet 5 having a higher coefficient of friction than the sheet member 3 is affixed to a portion of the back surface (lower surface) of the sheet member 3 where the card member 1 abuts. When the card member 1 is inserted into 2, the card member 1 comes into contact with the rubber sheet 5, and the sheet member 3 to which the rubber sheet 5 is attached is drawn into the housing of the connector 2. .

The sheet member 3 may be any material as long as it is a flexible material such as a plastic sheet such as a film.
Further, the rubber sheet 5 is such that when the card member 1 comes into contact, the sheet member 3 to which the rubber sheet 5 is adhered and integrated is pulled into the housing of the connector 2 together with the insertion of the card member 1. What is necessary is just to have a friction coefficient.

  Here, the case where the rubber sheet 5 is pasted on the portion of the sheet member 3 where the card member 1 abuts will be described as an example, but the surface of the sheet member 3 that increases the friction coefficient at the portion where the card member 1 abuts. As long as the part where the card member 1 abuts has a higher coefficient of friction than other parts, such as being treated, the rubber sheet 5 is not limited to sticking, and any form may be used.

FIG. 6 is a schematic cross-sectional view showing a state in which the card member 1 is inserted partway into the connector 2 in the first embodiment, that is, a state in which the card member 1 is not inserted (not inserted).
FIG. 7 is a schematic cross-sectional view showing a state where the card member 1 is completely inserted into the connector 2 in the first embodiment.

  As shown in FIG. 6, in a state where the card member 1 is not completely inserted into the connector 2, the mark 4 provided on the surface (upper surface) of the sheet member 3 can be visually recognized from the outside, but the card member 1 is attached to the connector 2. In the state where the insertion is completed, as shown in FIG. 7, the mark 4 enters the inside of the housing of the connector 2 and cannot be visually recognized from the outside.

  That is, if the user (operator) inserts the card member 1 into the connector 2 until the mark 4 is not visible, the card member 1 can be prevented from being incompletely inserted. Further, if the mark 4 is visible, it can be recognized that the card member 1 is incompletely inserted, so that the card member 1 is not completely inserted into the connector 2 and a component is attached in front of it. There is no need to close the cover and re-install the parts again, which is efficient.

  In the state where the card member 1 is completely inserted into the connector 2, as shown in FIG. 7, the sheet member 3 (including the rubber sheet 5) presses and presses the upper surface portion of the inserted card member 1 from above. Therefore, the sheet member 3 also has a function as a lock mechanism that fixes the card member 1 so that the card member 1 does not come out of the connector 2. Therefore, the rubber sheet 5 is more effective as the rubber sheet has a higher friction coefficient.

  Further, the card member 1 inserted into the connector 2 is in a state in which the upper surface portion is pressed from above by the sheet member 3, so that even if external vibration or impact is applied to the connector 2, the sheet member 3. Vibration and impact can be suppressed by the elastic force.

When the card member 1 is discharged from the connector 2, the portion protruding from the opening 22 of the sheet member 3 may be pulled out to the state before inserting the card.
FIG. 8 is a schematic cross-sectional view showing a state when the card member 1 is discharged from the connector 2 in the first embodiment.

  As shown in FIG. 7, when the card member 1 is ejected from the state in which the card member 1 is completely inserted into the connector 2, the sheet member 3 protruding from the opening 22 of the connector 2 is indicated by the arrow shown in FIG. 8. By pulling out in the direction of A, as shown in FIG. 8, the sheet member 3 is pulled out, the bent portion disappears, and the elastic force holding the card member 1 disappears.

  Thereby, the pressure-bonding force for pressing the upper surface portion of the card member 1 is lost, and the holding mechanism (locking mechanism) for fixing the card member 1 does not function, so that the card member 1 can be easily taken out from the connector 2. .

  As described above, according to the first embodiment, it is possible to easily recognize the insertion position of the card member by confirming the pull-out amount (projection amount) of the sheet member mounted on the connector. Incomplete insertion into the connector can be prevented.

Embodiment 2. FIG.
FIG. 9 is a perspective view showing a state before insertion when the card member 1 is inserted into the connector 2 in the second embodiment. In addition, the same code | symbol is attached | subjected to the structure similar to what was demonstrated in Embodiment 1, and the overlapping description is abbreviate | omitted. In the second embodiment described below, the sheet member 3 has a stopper mechanism as compared with the first embodiment.

  In the first embodiment, as shown in FIG. 5, one end of the sheet member 3 is fixed to the surface side in which the opening 22 inside the housing of the connector 2 is formed, and the sheet member 3 is bent while being bent. The other end side is drawn out of the housing from the opening 22. However, in this state, the position at which the card member 1 and the sheet member 3 (including the rubber sheet 5) abut when the card member 1 is inserted into the connector 2 is always constant due to the amount of bending of the sheet member 3. Not always.

Therefore, in the second embodiment, the sheet member 3 is provided with a stopper mechanism so that the amount of bending of the sheet member 3 is constant.
The sheet member 3 shown in FIG. 9 includes a stopper 31 that is a cut-out portion of the sheet member 3 and bent as an example of a stopper mechanism.

  The stopper 31 abuts against the opening edge of the opening 22 of the connector 2 and restricts the sheet member 3 from being pulled into the housing from the opening 22 before the card member 1 is inserted into the connector 2. . When the card member 1 is inserted and the inserted card member 1 is brought into contact with the inside of the housing and the sheet member 3 is pulled in, the stopper 31 is deformed along with the sheet member 3 so that the inside of the housing is naturally formed. It is supposed to be drawn into.

  That is, the stopper 31 prevents the sheet member 3 from being further bent and entering the housing of the connector 2 when the card member 1 is not inserted into the connector 2, and keeps the bending amount of the sheet member 3 constant. be able to.

FIG. 10 is a schematic cross-sectional view showing the structure of another example of the connector 2 in the second embodiment.
In this example, instead of the stopper 31 shown in FIG. 9, a stopper 51 is provided at one end of the rubber sheet 5 affixed to the portion of the back surface (lower surface) of the sheet member 3 that contacts the card member 1.

  The stopper 51 is formed only from the opening 22 when the card member 1 is not inserted into the connector 2, that is, when the card member 1 is not inserted into the connector 2. 2 is formed by bending only the end protruding to the outside without being attached to the sheet member 3.

  Also in this case, the stopper 51 contacts the opening edge of the opening 22 of the connector 2 and the sheet member 3 is pulled into the housing from the opening 22 before the card member 1 is inserted into the connector 2. To regulate that. Further, when the card member 1 is inserted and the inserted card member 1 is brought into contact with the inside of the housing and the sheet member 3 is pulled in, the stopper 51 is deformed along with the sheet member 3 to naturally move inside the housing. It is supposed to be drawn into.

  That is, even when this stopper 51 is employed, when the card member 1 is not inserted into the connector 2, the sheet member 3 is prevented from further entering the housing of the connector 2, and the amount of bending of the sheet member 3 is prevented. Can be kept constant.

  In the second embodiment, as the stopper provided in the sheet member 3, the stopper 31 is formed by cutting and bending a part of the sheet member 3, or attached to the sheet member 3 and integrated with the sheet member 3. The stopper 51 formed by bending only the front end of the rubber sheet 5 without being attached to the sheet member 3 has been described as an example. However, the stopper 51 is in contact with the opening edge of the opening 22 of the connector 2 so that the card member 1 is not attached. When the card member 1 is inserted while restricting the sheet member 3 from being pulled into the housing at the time of insertion and keeping the bending amount of the sheet member 3 constant, the card member 1 naturally enters the housing of the connector 2. Any form may be used as long as it has a certain strength.

  As described above, according to the second embodiment, in addition to the same effects as those of the first embodiment, the sheet member is provided with a stopper mechanism, so that the amount of deflection of the sheet member when the card member is not inserted into the connector. When the card member is inserted into the connector, the position where the card member and the sheet member (including the rubber sheet) contact each other can be kept constant, and the insertion position of the card member can be recognized more accurately. It becomes possible to do.
