Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card connector for connecting a small and thin card type device, and more particularly,
The present invention relates to the technology of a card connector having a mechanism for preventing an erroneous insertion of a card.

[0002]

2. Description of the Related Art There is known a card connector provided with an ejecting device of a type in which a card is inserted into a connector body at a set position and ejected from the set position by so-called push-push operation.

This type of card connector is actually used in 1-7
No. 5983, Japanese Utility Model Laid-Open No. 1-150387, and the like. In the card connectors described in these publications, a terminal member having contacts corresponding to the electric contact terminals on the card side is incorporated in the connector body. Further, a slider is slidably held in the connector body in the front and back of the card insertion direction.
When the card is inserted, the tip of the card abuts on the slider-side engaging portion, and the slider is designed to be pushed together with the card.

Further, a cam mechanism is adopted to enable push-push operation. The cam mechanism is composed of a combination of a cam portion and a pin member corresponding to the cam portion, and is arranged separately on the lower surface of the slider and the bottom surface of the connector body corresponding to the lower surface. In this card connector, the cam portion and the pin member are arranged separately in the thickness direction of the connector body, so that it is difficult to reduce the overall thickness of the card connector.

As a card connector in consideration of this point,
For example, the one described in JP-A-11-135192 is known. The card connector described in this publication is equipped with a cam mechanism for selectively positioning the slider at its forward and backward positions and its intermediate position. Further, the cam portion and the pin member of the cam mechanism are arranged separately between the side portion of the slider and the side wall of the connector body facing the side portion, thereby achieving a thin structure.

Among the card connectors of this kind, in the connector for small and thin cards, which has been particularly noticed in recent years, a smaller card including a memory stick having a length of several centimeters is used. Therefore, in this type of card connector, in order to contribute to downsizing and weight saving of electronic devices (for example, mobile computers, digital cameras, portable digital video cameras, etc.) equipped with the card connector, further miniaturization of the card connector itself, Also, we are trying to make it thinner.

[0007]

By the way, in the connector for a card provided with this push-push type ejecting device, since the card size is small, it is difficult to distinguish between the front and the back of the card itself. Therefore, it is difficult to determine whether or not the card insertion mode is normal. Therefore, the existing card connector has the following (1)-
The erroneous insertion pattern shown in (3) occurred.

(1) Incorrect insertion of the card into the connector body due to the reverse insertion of the card. (2) Incorrect insertion of the card into the connector body due to the reverse insertion. (3) Insert the card back and forth + insert the card back and forth ((1) + (2)).

When such an erroneous insertion occurs, it causes damage or bending of the terminal member provided on the connector body and the electrical contact of the card brought into contact with the terminal member.

Here, there are cases where the measure (2) for preventing the reverse insertion from the front and back is already adopted. For example,
In this method, the card insertion port of the connector body and the end face of the card have the same shape (similar shape) to prevent reverse insertion from the front and back. The existing card has stepped portions on both sides thereof for varying the thickness of the card. Corresponding to this, the shape of the card insertion slot is set.

Therefore, in principle, the card cannot be inserted upside down. However, in actuality, when the card is strongly inserted, the upper plate portion of the shield shell is slightly curved in the direction away from the housing, so that the card can be inserted even when the card is inserted upside down.

From the viewpoint of preventing erroneous insertion of a card, the shield shell may be reinforced or an erroneous insertion preventing member may be separately provided. However, this alone has a great influence on miniaturization and thinning of the connector.

According to the results of investigations and examinations by the inventors of the present application, among the erroneous insertion patterns of the cards shown in (1) to (3) above, the erroneous insertion pattern of (1) is the most frequent back and forth reverse insertion pattern. It turned out to be. The reason for this is that the insertion operation can be performed almost the same as when the card insertion mode is normal.

However, there is a problem that the terminal member on the connector body side is particularly damaged when the card is inserted backward and forward in this manner. Therefore, firstly, a solution to this point is desired.

Therefore, an object of the present invention is to provide a card connector capable of surely exhibiting the function of preventing the erroneous insertion of the card by a simple method while considering the miniaturization and thinning of the connector body.

[0016]

SUMMARY OF THE INVENTION The present invention comprises a card which is electrically connected by insertion into a connector body, the connector body being provided with a terminal member having a contact portion for contacting an electrical contact of the card. Housing, a metal shell that covers the housing, a card insertion opening provided between the metal shell and the housing, and an error that prevents card insertion during card insertion when the card insertion mode is not normal. An erroneous insertion prevention mechanism is provided with an insertion prevention mechanism, and the displacement means for displacing the card to the metal shell side during the insertion of the card and the insertion of the card by abutting against the end of the card displaced by the displacement means are prevented. A stopper means is provided, and the stopper means is provided on the metal shell.

According to the present invention, the displacement means for displacing the card toward the metal shell during the insertion of the card, and the stopper means for abutting against the end of the card displaced by the displacement means to prevent the insertion of the card. The card is equipped with an erroneous insertion prevention mechanism. This makes it possible to reliably prevent the card from being inserted during the insertion of the card when the mode of inserting the card into the insertion opening is not normal. Also,
Since the stopper means is provided on the metal shell, the erroneous insertion prevention function is surely exhibited even if the metal shell is slightly bent by an external force.

It is preferable that the displacing means of the card is set so as to displace the end portion of the card in a direction away from the contact portion before reaching the contact portion of the terminal member.
With such a setting, it is possible to prevent the end portion of the card from strongly contacting the contact portion of the terminal member.

Further, the displacing means of the card includes a first displacing means and a second displacing means which are arranged at intervals in the width direction of the housing.
Desirably, the first displacing means and the second displacing means include a displacing means, and each of them is constituted by a rib provided on the housing. Although one displacing means may be used, when two displacing means are provided at intervals, the function thereof can be further ensured. Also, the housing is usually made of resin, and the ribs can be formed together when the housing is molded. Therefore, it is possible to adopt a configuration in which it is not necessary to separately provide a member for the displacement means.

It is desirable that the rib be provided with a guide inclined surface which is directed toward the stopper means side in the card insertion direction. This is because the guide slope can surely displace the card toward the stopper means.
Further, since it is a mere slope, it can be formed at the same time when the rib is formed.

The metal shell includes an upper plate portion that covers the surface of the connector body and left and right side plate portions, and the stopper means includes an opening portion provided in the upper plate portion, and a card is provided at an edge portion of the opening portion. It is desirable that the end of the card is set so that it abuts while the card is being inserted. According to this structure, since it suffices to provide the opening in the metal shell, there is no need to separately provide a special member as the stopper means.
This can be achieved by simple means.

It is desirable that the edge portion of the opening is located closer to the card insertion opening than the contact portion of the terminal member.
This is because it is possible to prevent further insertion of the card before the end portion of the card reaches the contact portion. Thereby, the contact portion can be protected.

When the insertion mode of the card is normal,
It is desirable that the front shape of the card insertion slot and the end surface shape in the card insertion direction match each other. With this configuration, when the card insertion mode is normal, the card insertion is permitted, and when the card insertion mode is not normal, the card insertion is restricted. In particular, in the case of the front-back reverse insertion as well as the normal insertion, it can be inserted without difficulty at first, but the insertion becomes impossible in the middle, and the terminal member is protected.

It is desirable that thin portions extending in the lengthwise direction of the card are formed on both sides of the card, and that the thin portions are formed by stepped portions provided on the back surface of the card. When the thin parts are formed on both sides of the card, the end surface of the card is not rectangular. That is, the key portion is formed by the thin portion with respect to the thick portion.

The edge portion of the opening is formed in a straight line portion extending in the width direction of the housing, and the length dimension β of the straight line portion.
2 is the maximum width dimension α including the thin parts provided on both sides of the card
It is desirable that it is set larger than 2. With this setting, the end portion of the card is easily projected from the opening. As a result, the end portion of the card abuts on the straight line portion in the reverse insertion state.

It is desirable that a band plate portion extending in the width direction of the housing be present between the card insertion opening and the opening in the upper plate portion of the metal shell.
Since the band plate portion is easily bent, the end portion of the card easily comes into contact with the edge portion of the opening. That is, the greater the amount of bending of the strip portion, the more the card is displaced in the direction away from the housing. Therefore, the edge portion of the card more surely abuts the edge portion beyond that.

Of the edge portion of the opening, a small opening for leaving an edge portion of a length necessary for the corner portion of the end of the card to abut is provided on the upper plate portion of the metal shell, and a small opening portion is provided. The area can be formed small. According to this structure, it becomes easy to secure a suction area by a suction cup, an electromagnet, or the like at or near the center of the upper plate of the metal shell. This makes it possible to consider the mounting workability of the contacts.

[0028]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the present invention is applied to a card connector having a pressed portion and a thin portion will be described below. 1 is a plan view of a connector body according to Embodiment 1 of the present invention. FIG. 2 is a plan view showing a case where the card is not inserted into the connector body normally (reverse insertion). FIG. 3 is a plan view of the housing. FIG. 4 is a front view seen from the card insertion slot side.

The card connector 1 is formed in a generally rectangular plane as a whole. The connector 1 includes an ejecting device EJ for a card C that is inserted into the connector body B. The connector body B has an insertion slot 2 for the card C.
1 and a metal shell 3 that covers the housing 2. The housing 2 is made of an insulating resin and has a bottom plate portion 2a and left and right side wall portions 2
2 and 23, and a terminal mounting portion 24 provided near the one end of the housing 2.

The metal shell 3 is formed by punching and bending a thin metal plate having a spring property, and the upper plate portion 31 is formed.
And left and right side plate portions 32 and 33. The metal shell 3 is formed of a conductive metal plate so as to exert the electromagnetic shield function of the entire connector.

In the terminal mounting portion 24, a plurality of terminal members 4 having a contact portion 4a that comes into contact with the electrical contact e of the card C are incorporated. These terminal members 4 are provided at intervals in the width direction of the housing 2. Each terminal member 4 is
In addition to the contact portion 4a that contacts the electrical contact e of the card C, a solder tail 4b that is connected to a circuit board (not shown) is provided. The contact portion 4a and the solder tail 4b are in the insertion direction (opposite side) of the card C with respect to the insertion opening 21 of the card C.
It is located away from.

In this embodiment, an erroneous insertion preventing mechanism for the card C electrically connected by being inserted into the connector body B is provided. That is, the connector body B
Is provided between the housing 2 in which the terminal member 4 having the contact portion 4a that contacts the electrical contact e of the card C is provided, the metal shell 3 that covers the housing 2, and the metal shell 3 and the housing 2. Card insertion slot 21
An erroneous insertion prevention mechanism is provided to prevent the card C from being inserted while the card C is not inserted properly.

This erroneous insertion prevention mechanism constitutes first displacing means 201 and second displacing means 202 which constitute displacing means for displacing the card C toward the metal shell 3 during the insertion of the card C.
And the end 1 of the card C displaced by these displacement means
It is provided with stopper means 30 that abuts against 0 to prevent the card C from being inserted. The stopper means 30 is provided on the metal shell 3.

The first displacement means 201 of the card C is shown in FIGS.
As shown in FIG. 3, the rib is provided on the housing 2. The housing 2 is made of insulating resin. Therefore, by forming the ribs together when the housing 2 is molded, the first displacement means 201 and the second displacement means 2
02 is provided. As a result, there is no need to separately provide a member for each displacement means.

The rib as the first displacing means 201 displaces the end portion 10 of the card C in the direction away from the contact portion 4a before reaching the contact portion 4a of the terminal member 4 when the card C is inserted. Is set to. In particular,
The rib configuring the first displacing means 201 is the ninth terminal member 4 on the rightmost side when viewed from the insertion port 21 side of the card C.
It is provided in the back of.

The first displacing means 201 is formed of a rib having an appropriate height as shown in FIG. 3, and has an end portion 201a on the insertion port 21 side. The end 201a is located closer to the opening 21 than an edge portion 35a of the opening 35 described later. Therefore, the end portion 10 of the card C, which is inserted backwards and forwards, is lifted upward (upper plate portion 31 side) at this end portion 201a. As a result, the edge 10 of the card C
Is designed to abut the edge portion 35a. The first displacement means 201 is provided with a groove 201b for letting the contact portion 4a of the terminal member 4 escape in the thickness direction of the rib.

The other second displacing means 202 is arranged on the left side (between No. 7 and No. 8) when viewed from the insertion port 21 side. The rib as the second displacement means 202 is a card C.
The guide inclined surface 202g is provided toward the stopper means 30 side in the inserting direction. This guide slope 2
With 02g, the card C can be more reliably fixed to the stopper means 3
It is configured so that it can be displaced to the 0 side. Since the guide slope 202g is also a simple slope, it can be formed at the same time when the rib is formed.

Further, by providing the stopper means 30 on the metal shell 3 as described above, it is ensured that the erroneous insertion preventing function is surely exhibited even if the metal shell 3 is slightly bent by an external force.

The stopper means 30 includes an opening 35 provided in the upper plate portion 31 of the metal shell 3, and the opening 3
The end portion 10 of the card C is set so as to abut against the edge portion 35a of the card 5 while the card is being inserted. With this configuration, it suffices to provide the opening 35 in the metal shell 3. Therefore, this can be realized by a simple means without providing a special member as the stopper means 30.

The edge portion 35a of the opening 35 has a terminal member 4
It is located closer to the insertion port 21 side of the card C than the contact portion 4a. This prevents further insertion of the card C before the end 10 of the card C reaches the contact 4a,
It is designed to protect a.

As shown in FIG. 5, when the card C is inserted properly, the front shape of the insertion slot 21 and the end surface shape of the card C in the insertion direction (substantially the same as the hatched shape in FIG. 5) are used. Match each other. With this configuration, the insertion of the card C is allowed when the insertion mode of the card C is normal, and the insertion of the card C is regulated (prevented) when the insertion mode is not normal. Moreover, even if the card C is inserted in an abnormal manner when it is not inserted properly, the edge portion 35a of the opening 35 restricts the insertion of the card C.

The specific shape of the card C will be described.
As shown in FIGS. 2 and 5, on both sides of the card C, a thin portion 11 extending in the length direction of the card C is formed, and the thin portion 11 is a step portion 11a provided on the back surface of the card C.
Is formed by. By forming the thin portions 11 on both sides of the card C, the end surface (end portion) 10 of the card C is not rectangular. That is, the thin portion 11 with respect to the thick portion 12 forms a key portion. Therefore, the inner wall of the insertion slot 21 of the card C is provided with the convex portions 22a and 23a which enter toward the stepped portion 11a, respectively.

The edge portion 35a of the opening 35 is formed in a straight portion extending in the width direction of the housing 2 (here, the same portion as the edge portion), and the length dimension β2 of the edge portion 35a is provided on the card C. Is set to be larger than the width dimension α2 including the thin portion 11 (see FIG. 1). The opening 35 is formed with a dimension β1 portion shorter than the length dimension β2 of the edge portion 35a. With this setting, the end portion 10 of the card C is easily projected from the opening 35. As a result, the card C is inserted in the front-reverse insertion mode shown in FIG.
The end portion 10 of the abuts against the edge portion 35a.

The upper plate portion 31 of the metal shell 3 has a band plate portion 36 extending in the width direction of the housing 2 between the insertion slot 21 of the card C and the opening 35. Since the strip plate portion 36 is easily bent, the end portion 10 of the card C is easily brought into contact with the edge portion 35a of the opening 35. That is, the greater the amount of bending of the strip portion 36, the more the card C is displaced in the direction away from the housing 2. Therefore, the edge portion 10a of the card C can be more reliably abutted against the edge portion 35a at the tip thereof.

As shown in FIG. 1, the strip plate portion 36 is formed such that the width in the vicinity of the central portion is narrower than the widthwise end portions. By forming in this way, the band plate portion 36 can be made to have a shape that is more easily curved.
Is formed into a substantially rectangular plane having the edge portion 35a as a long side. By forming in this way, the opening 35
The function of itself can be effectively exhibited.

In this embodiment, the dimension β3 of the opening 35 corresponding to the length direction of the housing 2 is set larger than the width dimension β4 of the strip plate portion 36. The reason for this setting is that the end portion 10 of the card C can be reliably abutted against the edge portion 35a of the opening 35 by utilizing the bending action of the band plate portion 36. That is, if the dimension β3 is too small, the edge portion 35a comes too close to the strip plate portion 36. As a result, the function of the strip plate portion 36 may not be effectively exerted.

The electrical contacts e of the card C are arranged in two rows on one surface (front surface) of the card C with a gap in the insertion direction of the card C, and each row extends in the width direction of the card C (see FIG. 2). ). This is because when the electrical contacts e are arranged on one side of the card C, it becomes easier to consider the miniaturization and thinning of the connector as compared with the case where the electrical contacts e are provided on both sides.
That is, when the electrical contacts e are provided on both sides of the card C, the terminal members 4 also have to be provided in two stages with respect to the housing 2, and the connector itself is thickened accordingly.

The ejecting device EJ is pushed along with the insertion of the card C and slides between the forward position, which is the mounting position of the card C, and the retracted position, which is the initial insertion position of the card C, and the slider 5. 5, a coil spring 6 for urging the card 5 back toward the retracted position of the card C, and a cam mechanism 7 for restricting the sliding movement of the slider 5.
And (see FIG. 1).

The cam mechanism 7 is provided on the surface of the slider 5, and has a first guide groove for determining the forward movement position of the slider 5,
The slider 5 includes a second guide groove (not shown) that determines the retracted position of the slider 5, and a pin member 8 that is guided along each guide groove and determines the slide position of the slider 5. Then, the slider 5 is housed in a recess provided along the side portion of the housing 2 and covered with the metal shell 3.

In this embodiment, as shown in FIG. 2, when the card C is inserted backward and forward (backward insertion), the card C is moved by the end face 201a of the first displacement means 201 and the guide slope 202g of the second displacement means 202. The end portion 10 of the sheet is displaced so as to be lifted, and the end portion 10 strikes the edge portion 35a of the opening 35, and further insertion is prevented. Since the positions where the first displacing means 201, the second displacing means 202, and the stopper means 30 are provided are on the front side of the contact portions 4a, each contact portion 4a is reliably protected.

When the card C is properly inserted, the first displacing means 201, the second displacing means 202 and the stopper means 30 almost do not function, and the card can be inserted up to the normal setting position.

6 and 7 are plan views showing another embodiment of the present invention. In these figures, the same components as those in the previous embodiment are designated by the same reference numerals to simplify the description.

In this embodiment, the structure of the opening 45 provided in the upper plate portion 31 of the metal shell 3 is different from that of the previous embodiment, and the other structures are basically the same. That is, the opening portion 45 has a rectangular shape in which the length dimension β5 corresponding to the length direction of the housing 2 is formed small, and instead, the small opening portion 55 is provided.

The small opening 55 has a substantially triangular shape and has an edge portion 55a extending in the width direction of the housing 2. This edge portion 55a is the opening 35 shown in the previous embodiment.
Exists at a position corresponding to the edge portion 35a of the. However,
The small opening 55 is provided at a position closer to one side (the 9th terminal member 4 side) of the housing 2 in the width direction. The length dimension of the edge portion 55a of the small opening 55 is shorter than that of the edge portion 35a in FIG.

A portion 56 of the upper plate portion 31 exists between the small opening portion 55 and the opening portion 45. This portion 56 also has a strip plate shape that is easily bent due to its elasticity. The edge portion 55a is located closer to the insertion port 21 side than the contact portion 4a of the terminal member 4.

That is, in this embodiment, of the edge portion 35a of the opening portion 35, a small opening portion 55a for leaving an edge portion 55a of a length necessary for the corner portion of the end portion 10 of the card C to abut. Is provided on the upper plate portion 31 of the metal shell 3 to reduce the area of the opening 45. This structure is for facilitating to secure the suction area P by the suction cup, the electromagnet, or the like in the central portion of the upper plate portion 31 of the metal shell 3 or in the vicinity of the central portion. This makes it possible to consider the mounting workability of the contacts.
