Description

Card plugin

The present invention relates to a card connector installed in various electronic devices such as a portable telephone, a PDA (personal digital assistants), a portable digital acoustic player, a game machine device, a digital camera, and an information terminal device. Use the IC card to make an electrical connection between the IC card and the device.

The IC card is embedded in an IC (integrated circuit). As a type of IC card, a memory card using a nonvolatile memory is widely used. A memory card such as an SD memory card is used as a removable recording medium, and is used in a portable digital acoustic player, a digital camera, or the like. Further, in the portable telephone, a SIM card (user identity module card, or a subscriber identity module card) that records the unique ID number of the user is used.

The IC card is set to be inserted/extracted with respect to the card plug-in. For example, an IC card that accommodates a chuck of an IC card or the like can be taken out from the casing by operating the push pin, or the IC card or the IC card mounted on the adapter can be opposed to the casing by a so-called push-in/out mode. Insertion/extraction, etc., are well known.

In the card insert, there is provided a switch for detecting whether the IC card is mounted relative to the card insert. In other words, such a card insert is known by a switch that is switched in conjunction with the movement of the insertion/extraction of the IC card, and the card insert is known (refer to Patent Document 1). The detection result of the switch is used for switching control of the state of the live conductor/non-charged conductor of the signal transmission contact of the signal transmission terminal of the card.

The switch described in Patent Document 1 will be described with reference to FIGS. 18, 19, and 20. The switch 10 includes a first contact 1 and a second contact 2 each formed of a conductive plate, and is formed in an L-shaped cross section, and is disposed such that a plate surface thereof forms a right angle. The first contact 1 includes a first spring portion 11 having a flat plate shape, and the first spring portion 11 is an operation portion 12 that is convexly curved from the one end side toward the upper side, and the contact base portion 13 that extends flat from the front end of the operation portion 12 From the contact base The inclined portion 14 which is inclined toward the upper side of the portion 13 and the contact piece 15 which is formed by the flat surface which is bent upward from the front end of the inclined portion 14 are further provided. The contact piece 15 and the first spring portion 11 are formed such that the respective planes are orthogonal to each other. The first contact portion is constituted by the inclined portion 14 and the contact piece 15 connected to the contact base 13.

The second contact 2 of the switch 10 includes a second spring portion 21 that is disposed such that the plane of the second contact 2 is orthogonal to the flat surface of the first contact 1, as the planar portion 22 of the front end of the second spring portion 21, and The guide piece 23 whose upper end of the flat portion 22 is bent outward is bent. The surface formed as the inclined portion 14 and the surface of the guide piece 23 are substantially parallel. The second contact portion is formed by the flat portion 22 and the guide piece 23.

When the operation of the switch 10 is described with reference to FIGS. 19 and 20, the operation portion 12 of the first contact 1 is pressed in the Y direction as indicated by an arrow when the IC card is inserted. In the previous state of pushing, the first contact 1 and the second contact 2 are in a non-contact normally open state (switch open state).

Due to the pressing, the inclined portion 14 of the first contact 1 and the contact piece 15 are in contact with the guide piece 23 of the second contact 2, and the second contact 2 is pressed in a direction substantially orthogonal to the pressing direction Y, thereby Variable Bit. The X direction becomes the thickness direction of the housing of the card insert. As the first contact 1 is displaced in the Y direction, the contact portion of the first contact 1 gradually moves downward along the slope of the guide piece 23, becoming the contact piece 15 of the first contact 1 and the second contact 2 The state in which the flat portion 22 is in surface contact (that is, the state in which the switch is fully turned on).

In the switch described in Patent Document 1, the displacement direction X of the second contact 2 is orthogonal to the pressing direction Y, and the second contact 2 can maintain a certain amount of displacement irrespective of the amount of displacement of the first contact 1. . Therefore, even when the displacement amount of the first contact 1 is large, the amount of displacement of the second contact 2 can be suppressed to be small. Further, the second contact 2 is not displaced to a certain amount of displacement or more, and stable contact can be maintained.

[Patent Document 1] Japanese Patent No. 3635398

In the switch described in Patent Document 1, the displacement direction X of the second contact 2 is the thickness direction of the card insert, and the displacement amount of the second contact 2 corresponds to the thickness of the casing of the card insert. Therefore, in the case where the thickness of the casing is made thin, the amount of displacement becomes small, and there arises a problem that the contact pressure required for the first contact 1 and the second contact 2 cannot be sufficiently ensured. Therefore, there is a limit to the low height of the card insert. Further, the direction of the spring span of the first contact 1 and the direction of the spring span of the second contact 2 are substantially parallel at the same place, and therefore, it is difficult to make the length of the inclined surface of the guide piece 23 long. When the first contact 1 is mounted with respect to the second contact 2, the load of the second contact 2 is sharply applied with respect to the first contact 1. As a result, the first contact 1 does not return to the original position due to the frictional force of the first contact 1 and the second contact 2, or the first contact 1 is distorted, and there is a risk of bending.

The present invention has been made in view of such problems in the prior art, and an object thereof is to provide a card insert that can solve the above problems of the conventional switch.

In order to solve the above problems, the card insert of the present invention includes a case, a card inserted into the card body or a disk on which the card body is placed, and a flat storage space capable of accommodating the card body or the disk; the first contact of the leaf spring shape One end side is fixed to the casing, and the other end side is flexed by being in contact with the card body or the disk inserted into the storage space; the slit is open at the other end, and is formed from the other end side of the first contact toward the one end side, because a force applied by a plate surface direction of the first contact, the slit width is narrowed; and a plate-shaped second contact fixed to the housing at one end side; wherein the first contact is energized by the first contact The end surface on the other end side is bent toward the board surface, comes into contact with the second contact, and slides.

According to the present invention, since the first contact can be flexed in the card housing space, the necessary load can be secured even when the housing of the card insert is lowered in height. Further, the frictional force after the contact between the first contact and the second contact can be gradually increased with the movement of the first contact, and the load of the second contact can be prevented from being sharply applied to the first contact as in the conventional configuration. The problem. That is, it is possible to avoid the problem that the friction of the first contact and the second contact cannot be restored to the original position, and the problem that the first contact is distorted to cause bending.

Embodiments of the present invention will be described below with reference to the drawings. The first implementation described below The form and the second embodiment are suitable specific examples of the present invention, and various technical limitations are imposed on constituent elements, types, combinations, shapes, relative arrangements, and the like, but these are merely examples, and the present invention is not limited thereto. .

[1. First embodiment]

A card insert according to a first embodiment of the present invention will be described.

Fig. 1 is a cross-sectional view showing the card insert cut in a plane coinciding with the insertion/extraction direction of the IC card. As shown in FIG. 1, the card insert includes an insulating plate 31, and a shield cover 32 disposed opposite the insulating plate 31. The casing is constituted by the insulating plate 31 and the shield case 32. The insulating sheet 31 is a molded article of, for example, a liquid crystal polymer. The shield case 32 is formed by bending a metal such as stainless steel. An IC card such as a SIM card is inserted into a card housing recess formed inside the casing from the card insertion opening 33 at one end surface of the casing. In the present specification, the side of the card insertion opening 33 is referred to as the front or the front side, and the opposite side of the card insertion opening is referred to as the rear or back side. When viewed from the card insertion opening, the right side surface is referred to as the right or right side surface, and the left side surface is referred to as the right side or the right side surface. For the left or left side.

As a SIM card, there is a micro SIM card having a smaller shape than a standard SIM card, or a nano SIM card smaller than a micro SIM card. The SIM cards are different in size, but the physical characteristics such as the pin configuration are the same as each other. The invention is applicable to any SIM card. Further, it is also applicable to other IC cards such as an SD memory card. Further, the present invention can be applied even when an IC card having a different size is attached to an adder and used in the same manner as a standard IC card. Further, the present invention can be applied even when a card insert is provided with a disk and the IC card is placed on the disk. The card body means an IC card or an adder.

2 and 3 are perspective views of the insulating plate 31 in a state in which the shield case 32 is removed. As shown in FIGS. 2 and 3, the insulating plate 31 integrally forms a right side wall 34a, a left side wall 34b, a rear wall 34c, and a front wall 34d adjacent to the card insertion opening 33, thereby forming a storage space in which an IC card can be housed. The shield case 32 is attached to the insulating plate 31 and fixed by welding or the like.

On the SIM card, eight pins (also referred to as electrodes, terminals, pads) are formed by gold plating, and each pin is assigned as a data input/output terminal, a ground terminal, a power input terminal, and the like. For example, in the case of a SIM card for a portable telephone, six pins are actually used in eight pins. Corresponding to the pin configuration of the SIM card, six contacts 35a, 35b, 35c, 35d, 35e, 35f are respectively disposed on the insulating plate 31. When it is not necessary to separately distinguish the contacts, it is simply referred to as the contact 35.

The contact 35 is, for example, a spring contact made of phosphor bronze, cut from the bottom surface of the housing The front end is set to the contact surface with the pins of the SIM card. The other end of the contact 35 is led to the lower side of the insulating plate 31, facing the opening 36 formed in the insulating plate 31. The other end of the contact 35 is soldered to the wiring pattern on the printed wiring board provided in the casing, and is electrically connected between the IC card inserted into the card insert and the printed wiring board. The contact 35 is provided on the insulating plate 31 by, for example, insert molding. Metal parts other than the contacts 35 are also inserted into the insulating plate 31 by insert molding. However, components such as the slider 41, the coil spring 42, and the guide pin 43 which will be described later are different from the insulating plate 31.

The first embodiment of the present invention inserts/extracts an IC by push-in/out mode card. In other words, in the push/pull method, the press-in operation and the pull-out operation are performed by repeating the operation force in the same direction. Specifically, a heart-shaped cam type push-in/out mechanism is used. The present invention is not limited to the push-in/out mode, and can be applied even to a card insert in which the IC card is locked and the lock pin is operated so that the IC card is detached from the card insert.

As shown in FIGS. 2 to 6, a metal made to reciprocate with the IC card, for example, The slider 41 made of stainless steel is disposed in the card housing space. One end of the slider 41 on the card insertion opening side is energized by the coil spring 42 in the ejecting direction. The coil spring 42 is disposed in a metal spring housing that is disposed along the right side wall 34a of the insulating plate 31. The other end of the slider 41 is bent substantially at a right angle so that the abutting portion of the front end of the IC card is in contact with the front end of the slider 41. When the IC card is inserted into the card insertion space, the slider 41 and the IC card are integrally slid rearward in opposition to the energizing direction of the coil spring 42.

Relatively formed in the hole of the slider 41, one end of the guide pin 43 is freely inserted In. That is, one end of the guide pin 43 is bent, and one end is inserted into the support hole of the slider 41 to constitute the center axis of rotation of the guide pin 43. The other end of the guide pin 43 is freely rotatable, and the front end of the other end of the bend is inserted into the pin guide groove 44. A pin guide groove 44 is formed on the insulating plate 31.

As shown in FIG. 7, the pin guiding groove 44 is provided on both sides of the heart-shaped heart-shaped cam 45. The outward path guiding groove portion 46 and the circuit guiding groove portion 47 are provided, and the returning common groove portion 48 is provided at the joining portion of the outward path guiding groove portion 46 and the circuit guiding groove portion 47.

The end of the guide pin 43 is inserted into the pin guide groove 44 along the outward guide groove portion 46. And the loop guiding groove portion 47, the end portion is circulated. The push-in/out mechanism is constituted by the pin guide groove 44 and the end of the guide pin 43. On the bottom surfaces of the outward path guiding groove portion 46, the circuit guiding groove portion 47, and the returning common groove portion 48, segment portions 49a, 49b, 49c, 49d for restricting the movement direction are provided so that the end portion of the guide pin 43 is along the above The outward guiding groove portion 46, the circuit guiding groove portion 47, and the returning common groove portion 48 are not reversely returned in the cycle.

The segment portion 49a is provided so as to reach the end side of the outward path guiding groove portion 46. The end of the pin 43 does not return to the side of the outward path guiding groove portion 46, but is stopped toward the stop position c of the heart-shaped cam 45 as a concave portion. The segment portion 49b is provided such that the end portion does not return from the stop returning stop position c to the segment portion 49a side. The segment portion 49c is provided such that the end portion of the guide pin 43 that advances from the stop return stop position c toward the circuit guide groove portion 47 does not return to the stop return stop position c. The segment portion 49d is provided such that the end portion of the guide pin 43 that enters the outward path guiding groove portion 46 and the returning common groove portion 48 from the end of the circuit guiding groove portion 47 does not return to the circuit guiding groove portion 47.

As shown in FIG. 4, the IC card 50 is pushed out, that is, the IC card 50 is pulled out. In the moving state, the end of the guide pin 43 is located at the push-out stop position a. Then, when the push-in operation, that is, the push-in operation, is performed, the end portion reaches the push-in operation end stop position b by the outward guide groove portion 46, and when the push-in operation force is released at the position, the spiral is caused by the screw The spring force of the spring 42 reaches the stop return stop position c. 5 and 6 show the state after the pushing operation.

Then, by the memory card pressing operation for releasing the re-engagement, that is, pushing In the action, the end of the guide pin 43 reaches the push-in operation end stop position d. Then, by releasing the press-fitting operation force, the end portion is returned to the push-out stop position a by the return-guiding groove portion 47 by the spring force of the coil spring 42.

In the first embodiment of the present invention, it is used to detect the IC card 50 relative to the card insert. The switch 51 that is in the push-in state is provided in the card storage space. In other words, the switch 51 that is switched in conjunction with the movement of the insertion/extraction direction of the IC card detects the insertion/extraction state of the IC card 50, and the detection result is used for switching control of the charged/non-charged state of the signal transmission contact 35. Wait.

The switch 51 will be described in detail with reference to FIGS. 8 , 9 , 10A, and 10B. open The closing 51 is composed of a first contact 52 and a second contact 53. The first contact 52 and the second contact 53 are spring contacts made of phosphor bronze, and are provided in the rear of the card housing recess of the insulating plate 31 by insert molding. The terminal electrically connected to the first contact 52 and the terminal electrically connected to the second contact 53 are led out to the side surface or the bottom surface of the insulating plate 31, and are connected to the external printed wiring board.

The first contact 52 is substantially orthogonal to the insertion/extraction direction of the IC card 50. The leaf spring of the plate surface is fixed to the insulating plate 31 by insert molding in the vicinity of the rear wall 34c of the card housing recess. The front end of the plate-shaped spring portion 54 of the first contact 52 is extended, and is elastically raised toward the card insertion opening side, and a semicircular projection is provided. Further, the bending is such that the front end is parallel to the card insertion/extraction direction. The semicircular protruding portion is an operation portion 55 that is in contact with the front end surface of the IC card 50.

The first contact 52 includes a thin strip-shaped slit 56, the other end of which is open, from the first The other end side of the contact 52 extends toward one end side. For example, the slit 56 is formed to a position from the open end to the extent beyond the action portion 55. The slit 56 is formed at an intermediate position of the width of the first contact 52, and has a shape in which the opening width gradually decreases from the other end side of the first contact 52 toward the one end side. The lower end surface of the other end of the first contact 52 is provided as a contact portion 57 that is in contact with the second contact 53. The contact portion 57 has an inclination along the inclined contact surface of the second contact 53.

It is in contact with the rear wall 34c of the insulating plate 31 to form a window portion 58 provided with a plate spring. It has a plate surface parallel to the insertion/extraction direction of the card, and protrudes from the rear wall 34c toward the window portion 58. The central portion of the plate spring is cut and set as the second contact 53. A projection 59 projecting downward from the lower end surface of the spring portion 54 of the first contact 52 is formed, and the projection 59 is in contact with the corner portion 60 of the window portion 58 to restrict the first contact 52 from being opened more than necessary.

The second contact 53 is a chopped piece having an inclined surface that is inserted from the card The base on the side of the mouth rises toward the free end on the side of the rear wall 34c. The contact portion 57 of the first contact 52 is set to be in contact with the inclined surface. Further, the inclination is different so that the vicinity of the free end of the second contact 53 is further upward. This is to cause a larger contact pressure near the front end of the inclined surface of the second contact 53 when the contact portion 57 of the first contact 52 slides along the inclined surface of the second contact 53, so that the first contact pressure is made. The contact between the contact 52 and the second contact 53 is stable.

In other words, one end side of the second contact of the plate shape (the side of the rear wall 34c) is fixed to the above case. The second contact 53 has an inclined surface, and rises from the other end side of the second contact toward the one end side, and the end surface of the other end side of the first contact 52 is deflected toward the plate surface direction, and is in contact with the inclined surface. Slide it.

11A is an enlarged view showing a state in which the mounting of the IC card 50 is not completed, that is, a card push Out of state. In the card push-out state, the first contact 52 and the second contact 53 are in a non-contact state, and are in a switch-off state (normally open). When the IC card 50 is pushed in and the mounting end state is reached, as shown in FIG. 11B, the contact portion of the IC card 50 pushes the operating portion of the first contact 52, and the first contact 52 and the second contact 53 are pressed. Contact, become the switch on state. That is, the contact portion 57 of the first contact 52 is in elastic contact with the inclined surface of the second contact 53.

The switch 51 in which the IC card 50 is inserted and the first contact 52 is pushed by the IC card 50 The state change process is shown in Figs. 12A and 12B. 12A and 12B show a state in which the operation portion of the first contact 52 is pressed by the contact portion of the IC card 50, and the states are changed to the states Sa, Sb, and Sc.

The state Sa is a state in which the pressing operation of the IC card 50 does not occur, and indicates a state in which the first contact 52 and the second contact 53 are not in contact with each other. The state Sb indicates that the first contact 52 and the second contact 53 are in a non-contact state although the contact portion of the IC card 50 pushes the operation portion of the first contact 52. The state Sc indicates the contact state in which the mounting of the IC card 50 is completed and the first contact 52 and the second contact 53 are in contact. In the state Sa and the state Sb, the switch 51 is turned off, and in the state Sc, the switch 51 is turned on.

In the state Sc, the spring span direction of the first contact 52 and the spring span direction of the second contact 53 intersect at substantially right angles. The so-called spring span refers to the distance between the load support points of the leaf spring, and the spring span direction refers to the direction between the connection load support points. In the case of the first contact 52, the fixed position of the connection base and the direction of the movable front end become the spring span direction. In the case of the second contact 53, the direction of connecting the cut base and the front end of the cut and raised piece becomes the spring span direction.

During the change of the above state, FIG. 1213 shows the action of the first contact 52. In the state Sa and the state Sb, the first contact 52 and the second contact 53 are not in contact, and therefore, the front end portion of the slit 56 including the first contact 52 does not change. During the change from the state Sb to the state Sc, the contact portion 57 of the first contact 52 comes into contact with the inclined surface of the second contact 53, and the inclined surface of the second contact 53 is gradually pressed inward. In this case, the contact portion 57 of the first contact 52 is biased in the upward direction, and the spring formed by the lower side piece and the upper side piece sandwiching the slit 56 is moved to make the width of the slit 56 small.

The restoring force of the spring constituted by the lower side piece and the upper side piece of the first contact 52 sandwiching the slit 56 gradually becomes stronger as it slides along the inclined surface after the first contact 52 contacts the second contact 53. Therefore, the contact pressure (frictional force) after the contact of the first contact 52 and the second contact 53 gradually becomes larger as the movement of the first contact 52 is increased. By such an action, it is possible to prevent the contact failure or the distortion of the contact such as the conventional switch described above from causing the bending.

Further, in the first embodiment of the present invention, the desired contact pressure can be set by the width of the lower leaf spring portion of the slit 56 or the length of the slit 56 in the longitudinal direction. That is, the larger the width of the lower leaf spring portion, the larger the load generated by the spring, and the shorter the length of the slit 56, the larger the load generated by the spring.

[2. Modification of the first embodiment]

13A and 13B show a modification of the first embodiment of the present invention. An insertion/extraction direction is provided between the upper operation portion 55a of the slit 56 of the first contact 52 and the lower operation portion 55b. The step difference is 61. For example, the lower operation portion 55b that is in contact with the second contact 53 is set to be the same as the position of the operation portion 55 of the first embodiment. By bending the first contact 52, the upper operating portion 55a is placed closer to the insertion port side of the IC card, and a step 61 is formed.

That is, the upper and lower portions of the first contact 52 located at the slit 56 have a step in a direction substantially perpendicular to the spring span, and in the upper and lower portions, there is no portion in contact with the second contact 53 and The card body 50 or the disk is in contact with each other.

In this modification, the time during which the switch 51 is turned on/off can be adjusted by the size of the step 61. That is, when the step 61 is increased, when the IC card 50 is inserted, the time at which the first contact 52 starts to operate becomes earlier, and the switch-on time can be advanced. When the IC card 50 is taken out, if the step 61 is increased, the time until the start of the first contact 52 is delayed, and the switch off time can be delayed.

[3. Second embodiment]

A second embodiment of the present invention will be described with reference to Figs. 14 to 17 . As shown in FIG. 14, the switch 71 of the second embodiment is composed of a first contact 72 and a second contact 73. The first contact 72 is a leaf spring having a plate surface substantially orthogonal to the insertion/ejection direction of the IC card 70, and the base portion is fixed to the insulating plate 31 by insert molding in the vicinity of the rear wall of the card housing recess. The first contact 72 is formed in a shape in which the free end of the spring portion 74 of the leaf spring whose plate surface is orthogonal to the insertion/ejection direction is bent back substantially 180° toward the opposite side of the card insertion opening side.

The plane on the side of the spring portion 74 of the curved portion is the operation portion 75. As shown in FIGS. 16A, 16B, and 17, the abutting portion of the distal end of the IC card 70 is in contact with the operation portion 75, and the first contact is pressed. 72. A slit 76 is formed near the free end of the bending return. The lower side piece and the upper side piece of the slit 76 are extended downward at substantially right angles, and are bent inward by the extended end to form contact portions 77a and 77b which can come into contact with the second contact 73. Thus, by bending the leaf spring back to form a double-ended front end portion, an action portion 75 that is in contact with the front end of the IC card 70 can be provided at one end portion, and two slits 76 can be formed at the other front end portion. Contact portions 77a and 77b.

The card insert shown in Figs. 15A to 17 is a push-in/pull-type card insert, but the IC card 70 uses an IC card of a different type from the first embodiment, for example, an SD memory card. The IC card 70 is provided with pins for external connection on the back side. Corresponding to the pin configuration of the IC card 70, in the card insertion The bottom surface of the insulating plate 81 of the member is provided with eight elongated strip-shaped contacts 82 and external connection terminals 83 by insert molding. The external connection terminal 83 is connected to an external printed wiring board. The contact 82 is a spring contact made of, for example, phosphor bronze. The insulating plate 81 is a molded article of, for example, a liquid crystal polymer.

Fig. 15B shows a state in which the card housing recessed portion of the card insert is inserted into the IC card 70, and the stage of the IC card 70 is not completed, and the stage in which the IC card 70 is mounted is shown in Fig. 16B and Fig. 17 . The above figure shows the state in which the shield case is removed. The casing is formed by the insulating plate 81 and the shield case. The card insert is provided with a slider 85 that is energized by the coil spring 84 in the discharge direction.

The pin guide groove 87 of the heart cam 86 is formed for the slider 85. The front end portion of the guide pin 88 is slidably inserted into the pin guide groove 87. The base of the guide pin 88 is rotatably inserted into a recess formed in the insulating plate 81. The card-shaped cam 86 constitutes a locking mechanism, and constitutes a card insertion/ejection type card insert.

Further, a leaf spring 89 is provided on the card insertion side of the slider 85. The front end portion of the leaf spring 89 is bent in a U shape so that the convex portion of the leaf spring 89 protrudes toward the card housing recess. The convex portion of the leaf spring 89 enters the engagement recess 90 formed on the side surface of the IC card 70.

The switch 71 is provided in the card housing space of the card insert. The switch 71 is in a non-inserted state of the IC card 70 or an ejected state in which the IC card 70 is not pushed (FIG. 15B), and the first contact 72 and the second contact 73 are not in contact, and are in a switch-off state. As shown in FIG. 16B and FIG. 17, when the IC card 70 is pushed in with respect to the card insert, the mounting is completed, and the first contact 72 and the second contact 73 are in contact with each other, and the switch is in an ON state. In this way, the insertion/extraction state of the IC card 70 is detected, and the switching control of the wired/non-wired state of the signal transmission contact 82 is used based on the detection result. The second embodiment can have the same effects as those of the first embodiment. Further, the second embodiment has the two contact portions 77a and 77b, so that reliable contact contact can be achieved and the self-cleaning effect of the contact can be improved.
