[Patent Document 1] Japanese Patent Laid-Open Publication No. 2003-217738

The technique of Patent Document 1 disclosed above allows the exiting plate to enter along the guide wall of the frame. However, when the impact is applied, the engaging portion of the ejecting plate is deformed in a direction causing crushing, and it is not expected to further increase the holding force. In order to further improve the holding force, a large holding member or the like is required, which may cause an increase in the size of the card connector.

The purpose of this creation is to provide a card that inhibits large-scale and improves retention. Connector.

The card connector of the present invention which achieves the above object is formed with a housing space which is inserted in an insertion direction and has an insertion body in which a recessed portion is formed on a side surface in a width direction intersecting the insertion direction, and is characterized in that it is provided with: a plate having a latching portion at a proximal end portion in the insertion direction, the latching portion having a shape protruding toward the inside of the receiving space, and entering the latching recess of the insert body received in the receiving space to catch the insert; The slider is disposed so as to overlap on the jamming plate, and is slidable in the insertion direction, and the inserted discharge pin is pushed forward to slide in the insertion direction; and the ejector lever is disposed on the inner side of the accommodating space, and extends In the width direction, there is a rotating shaft in the middle, the first end is pushed and rotated by the slider sliding on the inner side in the insertion direction, and the insertion body is pushed out at the second end; the stuck plate is inserted in the direction in which the jamming plate is inserted The end side end portion has a jam releasing portion which is formed on a slope which is upward toward the inner side in the insertion direction, and is deflected downward by being pushed by the inserted discharge pin to move the jam portion downward, and Remove live recess.

In the card connector of the present invention, the jamming plate is flexed by inserting the discharge pin, and the jammer between the engaging recess of the insert body is released, and the jamming plate functions as a rigid body in the insertion direction. Therefore, even if a strong impact is applied in the direction in which the insert is withdrawn, the insert can be surely maintained.

Here, in the card connector of the present invention, the catching portion is preferably formed on the inclined surface together with the above-described jam releasing portion.

When the jamming portion is formed on the inclined surface, it is stuck when the insertion body is inserted into the accommodating space. Since the portion is pushed by the insertion body and is detached from the passage, a special mechanism for detaching the stuck portion when the insertion body is inserted is not required, and this portion realizes a simple structure.

Furthermore, in the present creation, the above-mentioned insert body can also be the card itself, and the card itself A jammed recess is formed. Alternatively, the insertion body may have a card holder in which a card is inserted and inserted into the accommodating space together with the card, and a jamming recess is formed in the card holder. When the card holder is formed with a stuck recess and the card is mounted on the card holder and inserted into the card type of the accommodating space type, the card itself does not need to be considered in relation to the stuck structure. Therefore, this creation is more suitable for a card connector of the type having a card holder.

When the card connector of the above creation is used, it does not cause an increase in size, and the insertion body in the inserted state can be prevented from being accidentally detached.

In addition, the fourth figure and the fifth figure show a top view and a cross-sectional view of the card connector in a state in which the tray accommodated in the accommodating space is pushed out and a state after being pushed out.

These third to fifth figures remove the metal casing 20. Moreover, these third to fifth figures are both superimposed in order to understand the positional relationship of the rack assembly 10 and the bracket 30. Further, in the third to fifth figures, (A) is a plan view, and (B) is a cross-sectional view taken along arrow A-A shown in the third (A) diagram.

The card connector 1 includes a frame assembly 10 (see FIG. 2), a metal case 20 (see the first drawing), and a bracket 30. A large opening 31 is formed in the center of the bracket 30, and a support table 32 is provided at the edge of the opening. A SIM card (not shown) is supported on the bracket 30 in such a manner that the periphery of the bottom surface of the SIM card is placed on the support base 32, and a large area at the center of the bottom surface of the SIM card is exposed from the opening 31 downward.

An insertion port 1a into which the bracket 30 is inserted is formed between the frame assembly 10 and the metal casing 20. Further, a receiving space 1b for receiving a SIM card placed in the state of the cradle 30 is formed in the insertion opening 1a (see, for example, the second drawing). The bracket 30 inserts the insertion direction indicated by the arrow A to the rack assembly 10. The bracket 30 of the embodiment is single, or the merging bracket 30 is placed on the bracket The SIM card of 30 corresponds to an example of the so-called insert in this creation.

Further, in the bracket 30, the width intersects with the insertion direction (arrow A direction) A jamming recess 33 is formed on the side of the direction. Further, the rack assembly 10 is provided with a chucking plate 12 (for example, refer to the third (B) diagram). The catching plate 12 is provided with a catching portion 121 having a shape protruding from the jam releasing portion 122 at the proximal end portion in the insertion direction (arrow A direction) toward the inside of the housing space. The catching portion 121 and the jam releasing portion 122 are formed on a slope that faces upward in the insertion direction (arrow A direction). When the bracket 30 is housed in the accommodating space 1b, the catching portion 121 enters the cradle 33 of the bracket 30 to catch the bracket 30, and serves to prevent the bracket 30 from being accidentally detached. Further, the jam releasing portion 122 serves as a character for releasing the stuck portion 121 as will be described later.

The rack assembly 10 is provided with a resin frame 11 as a base thereof, and the frame In the eleventh portion, the latching portion 121 that peepes down the stuck plate 12 and the opening 113 that catches the releasing portion 122 are formed. Further, the frame assembly 10 is provided with a plurality of metal contacts 13 integrally formed with the frame 11. Each of the contacts 13 has a substrate connecting portion 131 that is soldered to the surface of a circuit board (not shown). A solder pad serving as an electrical connection is formed under the SIM card placed on the cradle 30. The contacts 13 are in contact with the pads placed under the SIM card of the accommodating space 1b and placed in the cradle 30 to electrically connect the SIM card and the circuit board.

Further, the frame assembly 10 further includes a slider 14 and an ejector lever 15.

The slider 14 is a metal member disposed so as to overlap the chucking plate 12, and is slidably supported by the frame 11 in the insertion direction (arrow A direction) in the insertion direction (arrow A direction). .

A through hole 34 into which the external plug 40 for pressing the slider 14 is inserted (see FIG. 4 and FIG. 5) is formed in the bracket 30, and the frame 11 is also formed to receive the opening of the pin 40. Port 112.

In addition, the ejector lever 15 is disposed on the inner side of the accommodating space 1b, and is inserted in the side A metal member extending in the width direction intersecting (in the direction of the arrow A) is rotatably supported by the frame 11 in the middle thereof to form a rotating shaft 151. The ejector lever 15 is rotated by the slider 14 which is slid in the insertion direction (arrow A direction) on the first end 152, and is rotated in the counterclockwise direction (the arrow D direction shown in the fourth and fifth figures), and The second end 153 pushes the role of the cradle 30 out.

The bracket 30 in the taken-out state as shown in the first figure and the second figure is in the insertion direction (arrow A direction) is inserted from the insertion port 1a and accommodated in the accommodating space 1b. At this time, since the catching portion 121 of the catching plate 12 is formed on the inclined surface, the bracket 30 presses the catching portion 121. As described above, the frame 11 is formed with an opening 113 that peepes down the jamming plate 12 and the opening 113 of the jam releasing portion 122. Therefore, the jamming portion 121 pressed by the bracket 30 and the jam releasing portion 122 connected to the latching portion 121 are not disturbed by the chassis 11 (the arrow E shown in the fourth and fifth figures) The direction) is flexed, thereby ensuring the passage of the bracket 30. Then, when the bracket 30 is further inserted in the insertion direction (arrow A direction), as shown in the third figure, the second end 153 of the ejector lever 15 is pushed by the bracket 30 to rotate in the clockwise direction (arrow C direction). The slider 14 slides on the proximal end side in the insertion direction (the direction of the arrow B shown in the fourth figure). When the insertion bracket 30 is inserted to the position where the catching recess 33 reaches the catching portion 121 of the chucking plate 12, the catching portion 121 of the catching plate 12 enters the catching recess 33 of the bracket 30, preventing the bracket 30 from being accidentally released.

Here, since the jamming plate 12 is formed by the shearing process of the metal plate, and The catching portion 121 of the catching plate 12 is disposed such that the plate surface before the shearing process is oriented upward and downward, and expands toward the side surface of the bracket 30 to enter the catching recess 33. Therefore, the latching portion 121 is in the insertion direction ( The arrow A direction) acts as a rigid body. Therefore, even if the bracket 30 is hit in the detaching direction, the stagnation portion 121 can be prevented from being crushed and deformed, and the desired holding force can be maintained, and the bracket 30 can be strongly restrained.

As shown in the fourth figure, the plug 40 is inserted from the through hole 34 of the bracket 30 to the pin 40. When the slider 14 is pressed into the inner side in the insertion direction (arrow A direction), the front end of the latch 40 abuts against the jam releasing portion 122 of the chucking plate 12. Since the jam releasing portion 122 is formed on the inclined surface, it is deflected downward when the front end of the latch 40 is pushed (in the direction of the arrow E shown in the fourth and fifth figures). Then, the latch 40 hits the slider 14 in a state where the jam releasing portion 122 of the chucking plate 12 is deflected downward, so as to push the slider 14 in the insertion direction (arrow A direction) while chucking the board 12 Go on the way of sliding. The slider 14 pushes the first end 152 of the ejection lever 15 by the movement, the ejection lever 15 rotates in the counterclockwise direction (arrow D direction), and the second end 153 pushes the bracket 30 toward the proximal end side of the insertion direction (arrow B) direction). Here, when the latch 40 presses the latch releasing portion 122, the latching portion 121 of the chucking plate 12 provided beside the latching releasing portion 122 is also moved downward together with the latching releasing portion 122 to the separating and retaining recess portion. 33 stuck location. Therefore, when the cradle 30 is pushed by the ejector lever 15, the cradle 30 is pushed out to the state shown in the fifth figure after the state shown in the fourth figure. After the state shown in the fifth figure is pushed out, the nail or the like is placed on the bracket 30 to pull out the bracket 30.

In addition, the card connector 1 of the above-described embodiment is inserted into the bearer omitting pattern. The bracket 30 of the state of the SIM card. However, this creation can also be applied to a card connector in which a memory card other than the SIM card is carried in the cradle.

Further, the card connector 1 of the present embodiment is inserted into the SIM card and carried on the card holder. A card connector of the type on the shelf 30, but this creation can also be applied to a card connector of the type in which a card such as a memory card is inserted without a bracket. However, at this time, the card itself needs to be stuck in the recess.
