Description

  The present invention relates to a card connector, and more particularly to a tray-type card connector.

In recent years, in a portable terminal in which a plurality of types of cards can be mounted, it is a common practice to share a mounting slot for these cards in terms of structure and cost.
Patent Document 1 discloses a structure that is a card connector into which two types of cards can be attached, and that allows easy insertion of the cards. A microSD card is accommodated in the upper level, and a reverse type SIM card is accommodated in the lower level. According to this technique, a card connector that can be reduced in height by using a common outlet is obtained. Thereby, the card connector which can mount | wear with two types of cards can be assembled | attached to the portable terminal which consists of a thin case main body.

Patent Document 2 discloses a structure in which two types of cards having different sizes can be accommodated, and the protruding amount of each card is equal. Thus, the end of each card can be pressed with a simple structure such as a lid that closes the take-out opening, which contributes to miniaturization of the portable terminal.
Patent Document 3 discloses a connector structure that is a tray-type card connector and can easily increase the tray drawing stroke. According to this technique, even if the portable terminal is miniaturized, a card connector that allows easy insertion and removal of the card can be obtained.

  However, although the technology described in Patent Document 1 improves the insertability of the lower SIM card in the two-stage card connector of the SD card in the upper row and the SIM card in the lower row, it has been inserted in this technology. Card drawability is not considered. In particular, the upper SD card is inserted and removed at a relatively high frequency, and complicated operations are forced each time.

  That is, it is difficult to pull out only one of the two cards arranged in parallel between the adjacent parallel parts in such a manner that the end of the card is picked with a fingertip. For example, in the case where both cards have a push-push type ejector mechanism, there is a problem that the lower SIM card can be pulled out simultaneously when the upper SD card is pulled out. Further, in the system in which the end of the card is held and the card is pulled out, the further work is extremely difficult. Such a problem at the time of drawing out the card is commonly recognized in the techniques described in Patent Documents 2 and 3.

  The present invention has been made in view of such a problem, and in a mobile terminal in which a plurality of types of cards can be mounted, it does not hinder downsizing and low profile of the mobile terminal device, and only one of the cards is included. An object of the present invention is to provide a card connector that can be easily pulled out.

In order to achieve the above object, the card connector according to the present invention includes (1) another card connector (2) of a pull-out method or push-push method, and the card connector (1) in parallel to the circuit board surface. The other card (C2) accommodated in the other card connector (2) is in the state of being fitted to the other card connector (2), and the end portion is outside the edge of the circuit board. The card connector (1) protrudes, and a card part (C1) is inserted and removed by a tray having a handle part and a tray body, and a housing that forms an accommodation space for accommodating the card (C1) and the tray, And a contact base having a contact for electrical and mechanical connection to a pad of the card (C1), and received in the card connector (1). In the state where the card (C1) is fitted with the card connector (1), the handle portion protrudes outward from the edge of the circuit board, and the handle portion is attached to an end portion of the tray body, in a direction of inserting the tray into the receiving space, when the force of about pressing force generated to derive the further card in the mating position (C2) of the further card connector (2) is applied, the tray The main body is characterized in that the position where the force is applied is elastically recessed without changing the position.

  According to the present invention, the tray includes the handle portion extending outward from the end portion of the tray main body on which the card is placed. The handle portion is in a position protruding from the opening of the card connector when the tray body on which the card is mounted is accommodated in the accommodation space of the card connector. For example, when another card connector for an SD card is mounted on the surface of the circuit board opposite to the surface on which the card connector according to the present embodiment is mounted, the end of the SD card to be mounted on the card is similarly carded. The end face of the connector protrudes from the front end of the connector, and the end face is substantially at the same position as the end of the handle.

  When another card connector includes a push-push type ejector mechanism, the operation of pulling out the SD card is performed by pressing the end face of the SD card with a fingertip. During this pressing operation, the fingertips simultaneously abut against the handle portion in the parallel position and apply a pressing force to the abutment position of the handle portion. At this time, since the handle portion is configured to be elastically depressed by a pressing force enough to insert the card, it is simultaneously depressed by the pressing operation, thereby preventing the pressing operation. Further, since the pressing force is consumed for elastic deformation, it does not act on the tray body, and even if it is a push-push type ejector mechanism, the tray is not pulled out.

Also, even if another card connector is a method of pulling out the end of the SD card with a fingertip, the handle portion is not disturbed by the depression of the handle, so that the SD card can be pulled out without complicating the operation. be able to.
The tray may be formed integrally with the tray body and the handle. The tray may be made of a flexible synthetic resin, and may be made of a synthetic rubber such as silicone rubber or an elastic elastomer.

More preferably, in the card connector according to the present invention, (2) a pair of support portions in which the handle portion extends in the insertion / extraction direction, and a tray extending in a direction perpendicular to the insertion / extraction direction from near the tip of the support portion. And a gripping portion that grips during the insertion / extraction operation, wherein the gripping portion is elastically recessed with respect to a force in the insertion direction in cooperation with the support portion.

  According to this invention, the handle portion includes the support portion and the grip portion, and the grip portion is elastically recessed in cooperation with the support portion. Thereby, when there is another card connector at a position where the opening of the case is common, and another card connector has a push-push type ejector mechanism, the operation of pulling out the card is hindered by the elastic recess of the handle part. Absent. Further, since the pressing force is consumed for elastic deformation, it does not act on the tray body, and even if it is a push-push type ejector mechanism, the tray is not pulled out.

<Configuration of Card Connector> As shown in FIG. 7, the card connector 1 includes a housing 10, a base 20, a cover 40, and a tray 30. The housing 10 is a molded product made of a synthetic resin and is obtained by simultaneous molding with the base 20. The base 20 reinforces the housing 10 with a punched product of copper alloy and includes six contacts 25. The cover 40 is a molded product made of stainless steel and constitutes a part of the outer shell of the card connector 1.

<Housing> As shown in FIG. 1, the housing 10 includes a flat housing body 11 and a SW bar mounting portion 15 extending from a corner portion. The housing body 11 has six contact holes 12 formed in two rows. The housing 10 is obtained by simultaneous molding integrally with the base 20, and a contact 25 provided in the base 20 is disposed inside the contact hole 12. The housing body 11 is a flat plate having a rectangular shape when viewed from the front, has a small thickness, and cooperates with the base 20 to ensure strength.

  The SW bar mounting portion 15 is located some distance away from the housing body 11, and the SW bar S is assembled. The SW bar mounting portion 15 is at the tip of the extending portion that goes straight from the corner portion of the housing body 11 in the longitudinal direction. The SW bar S is a strip-shaped metal piece, and the thickness direction of the end portion is sandwiched and fixed by the groove of the SW bar mounting portion 15.

<Base> As shown in FIG. 2, the base 20 reinforces the strength of the housing 10 and is integrated with the housing by simultaneous molding so that the housing 10 supports the contacts 25. The base 20 forms a contact 25 from a metal rolled plate by punching, and forms side walls 22 and 22 at the edges by bending. The side wall 22 includes an engagement protrusion 23 for engaging with the cover 40 and a mounting portion 26. The engaging protrusion 23 is formed by deforming a part of the side wall 22 into a convex shape outward. The mounting portion 26 is configured by cutting a part of the U-shaped side wall 22 and is fixed to a pad of the circuit board P with solder.

  The base 20 is required to have high rigidity and conductivity. In particular, when a thin wall is required as in the present embodiment, a stainless material may be used. By using stainless steel, the reinforcing material of the housing 10 having a thin wall thickness and rigidity can be obtained. Further, since the base 20 is integrated with the cover 40 and a shielding effect is expected, it is desirable that the base 20 is a good conductor of an electric machine and the connection portion is electrically connected.

<Contact> The contact 25 includes a contact portion 250, a lead portion 251, and a fixing portion 252 as shown in FIG. 2. The contact portion 250 has a curved surface that is raised at an acute angle and has a slightly rounded tip. The curved abdomen makes electrical and mechanical contact with the corresponding terminal of the SIM card C1. The entire contact portion 250 is elastically displaceable and decreases in diameter toward the tip. The fixing portion 252 overlaps the housing body 11. The contact 25 is fixed to the housing 10 by this overlapping of the fixing portions 252. The lead portion 251 extends rearward and protrudes from the rear end edge of the housing 10.

<Housing / Base> The housing 10 / base 20 formed at the same time has a structure in which the housing body 11 is superimposed on the base body 21 as shown in FIG. The housing 10 is located inside the base 20, and the side end portions of the housing 10 do not overlap with each other and become a single base and are directly connected to the side walls 22 and 22. The contact 25 jumps upward from the contact hole 12 of the housing 10, and the lead portion 251 protrudes from the rear end edge of the housing 10. After the housing 10 and the base 20 are integrated with each other in the molding stage, the connecting bars that have gathered the contacts 25 are separated using a hole formed in the center of the housing body 11. As a result, each contact is electrically independent.

<Tray> The tray 30 includes a tray body 31 and a handle portion 35 as shown in FIGS. 4 and 5. The tray 30 is a molded product of a flexible material. For example, POM (polyacetal), synthetic resin such as 46 nylon, synthetic rubber such as silicone rubber, or a material having flexibility such as elastomer is suitable.

  As shown in FIGS. 4 and 5, the tray main body 31 includes a substantially rectangular bottom surface 31 a lacking in a mountain shape at the rear, and short side walls 31 b and 31 b on the left and right side surfaces. A handle portion 35 is provided in front of the tray body 31. A part of the handle portion 35 becomes the front wall 31 c of the tray body 31. The left and right side walls 31b, 31b, the front wall 31c, and the bottom surface 31a form a concave tray body 31, and the SIM card C1 is set therein. On the rear side of the bottom surface 31a, there is a recess 31aa for giving a feeling of completion at the time of fitting, and the side wall 31b is provided with a protrusion 31bb for giving a feeling of completion when being pulled out.

  As shown in FIG. 6, the SIM card C1 is placed in a concave tray body 31 including left and right side walls 31b and 31b, a front wall 31c, and a bottom surface 31a. The rear ends of the left and right side walls 31b, 31b are deformed inward so as to slightly hold both side ends of the rear surface of the SIM card C1. With such a structure, the SIM card C1 is accommodated in the tray body 31 leaving a slight clearance.

  The card connector 1 of this embodiment is of a reverse type, and the SIM card C1 is set on the tray 30 with the terminal surface from which the terminal C10 is exposed facing upward as shown in FIG. In order not to mistake the front and back of the SIM card C1, the front corner of the tray body 31 has a shape corresponding to a notch formed only at one corner of the SIM card C1.

  As shown in FIGS. 4 and 5, the handle portion 35 includes support portions 36 and 36 and a grip portion 37. The gripping portion 37 is a bar-shaped piece having a rectangular cross section, and is provided with support portions 36 and 36 at both ends. The support part 36 is connected to the front surface of the tray body 31. The handle portion 35 is used when the tray 30 is put in and out. In a state where the tray 30 is accommodated in the card connector 1, the handle portion 35 of the tray 30 projects from the insertion slot E of the card connector 1.

The handle portion 35 is a flexible molded product that is elastically easily deformable. In particular, the gripping portion 37 has a double-supported beam structure, and its cross section is smaller than the length in the longitudinal direction, and easily bends by a pressing force acting on the gripping portion 37. At this time, the support portions 36 at both ends also flex inward elastically.

  On the other hand, in the insertion operation of the tray 30, the high deformability of the handle portion 35 does not hinder the operation. The gripping portion 37 is near the front end of the tray body 31, and even if the inside of the gripping portion 37 that deforms inward contacts the front end of the tray body 31, the insertion force applied to the gripping portion 37 is directly applied to the tray body 31. Will not cause any problems.

<Cover> As shown in FIG. 7, the cover 40 constitutes the outer shell of the upper half of the card connector 1 so as to cover the housing 10 / base 20 from above. The cover 40 may use stainless steel when thinness and rigidity are required at the same time. The cover 40 has a cover body 41 as shown in FIG. The cover main body 41 includes an upper surface 41a and side walls 41b and 41b on the left and right side surfaces. The side wall 41 b includes an engagement receiving portion 43. The cover 40 forms a recess in the upper surface 41a and the left and right side walls 41b and 41b.

  As shown in FIG. 7, the cover 40 covers the housing 10 / base 20, forms an accommodation space 27 inside, and forms an insertion port E in front of the accommodation space 27. The engagement receiving portion 43 of the side wall 41b engages with the engagement protrusion 23 provided on the side wall 22 of the base 20 to electrically and mechanically connect the housing 10 / base 20 and the cover 40. The cover 40 is electrically coupled to the base 20 to form a shield structure in which the entire internal contact 25 is surrounded by a metal conductor.

<Tray Insertion / Extraction Operation> The tray 30 insertion / extraction operation will be described with reference to the drawings. FIG. 8 is an external perspective view showing the insertion / extraction state of the tray in which the SIM card is mounted on the connector, where (a) is before insertion and (b) is after insertion. FIG. 9 is an external perspective view showing a card insertion / removal method in which one side is an SD card connector and the other side is mounted with a SIM card connector according to an embodiment of the present invention, and FIG. Before, (b) is during push, and (C) is after push.

  The card connector 1 of the present embodiment is a reversible type, and as shown in FIG. 8, the SIM card C1 is not shown in the figure because it is placed on the opposite surface of the tray 30 in the figure. . The tray 30 on which the SIM card C1 is placed enters the card connector 1 in a posture in which the terminal surface of the SIM card C1 faces the circuit board P, as shown in FIG. The tray 30 enters from the insertion slot E of the card connector 1 mounted on the end of the circuit board P. The tray body 31 fits in the accommodation space 27 inside the card connector 1, and the handle portion 35 projects from the insertion slot E when in the normal fitting position. The protruding handle portion 35 protrudes from the edge of the circuit board P to the outside.

  When the tray 30 is inserted, the insertion force is particularly related to the grip portion 37 and is transmitted to the tray body through the support portions 36 and 36. As a result, the insertion force is applied to the tray body 31 and the tray 30 moves forward. When the tray 30 is pulled out, the handle portion 35 protruding outward from the insertion slot E of the card connector 1 is pulled out in a posture as it is with a fingertip. Since the handle portion 35 protrudes outward from the edge of the circuit board P, an operation of gripping the handle portion 35 can be easily performed.

<Principle of Operation, Portable Terminal with Two Cards> The card connector 2 for the SD card C2 is attached to the upper surface of the circuit board P, and the card connector 1 for the SIM card C1 is attached to the lower surface. The operation of pulling out the upper SD card C2 will be described with reference to FIG.
The card connector 2 for the SD card C2 includes a push-push type ejector mechanism. The card connector 2 for the SD card C2 and the card connector 1 for the SIM card C1 are located at the same position on the front and back of the circuit board P in order to make the card removal slot of the case common. As shown in FIG. 9A, the SD card C <b> 2 protrudes outward from the edge of the circuit board P in a state of being fitted to the card connector 2. Similarly, the SIM card C <b> 1 is fitted with the card connector 1, and the handle portion 35 protrudes outward from the edge of the circuit board P.

  In order to pull out the SD card C2, as shown in FIG. 9B, the SD card C2 is pushed with a fingertip so that a pressing force is applied to the rear end portion of the SD card C2. As a result, the SD card C2 enters the deep part of the card connector 2 and is disengaged during the operation. As a result, the SD card C2 receives a force in a direction in which the SD card C2 rolls out from the ejector device.

  By the way, the fingertip that pushes the rear end portion of the SD card C2 is also related to the handle portion 35 of the SIM card C1 in the lower stage at the same time, and the fingertip pushes the SD card C2 and the SIM card C1 simultaneously. At this time, the handle portion 35, in particular the grip portion 37, is deformed in the push direction in accordance with the push force in cooperation with the support portions 36, 36, so that the tray 30 of the SIM card C1 is operated to pull out the SD card C2. There is no hindrance. Further, since the tray 30 of the SIM card C1 is merely elastically deformed by the handle portion 35 by this push, an unscheduled operation does not occur. Even if the card connector 1 for the SIM card C1 includes a push-push type ejector mechanism, the SIM card C1 does not pop out by this operation.

<effect>
In the card connector 1 for the SIM card C1 of this embodiment, the handle portion 35 of the tray 30 is elastically deformed. Accordingly, when the SD card C2 is pulled out from the card connector 2 for the SD card C2 having the push-push type ejector mechanism provided side by side, it can be taken out without hindering the push operation.
In the card connector 1 for the SIM card C1 of this embodiment, the handle portion 35 of the tray 30 is elastically deformed. Thereby, when the SD card C2 is pulled out from the card connector 2 for the SD card C2 having the push-push type ejector mechanism provided side by side, the SIM card C1 is not mistakenly taken out.

The card connector 1 for the SIM card C1 of the present embodiment includes the erroneous insertion preventing piece 32 in the handle portion 35 of the tray 30. As a result, a mounting error due to a different direction of the SIM card C1 is prevented.
The card connector 1 for the SIM card C1 of this embodiment includes a tray 30 that achieves the purpose with a simple structure. As a result, it is possible to promote downsizing and thinning of the portable terminal without increasing the number of parts and increasing the cost.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the inventive idea.
