Description

Card connector

The present invention relates to a card connector, and more particularly to a card connector corresponding to a thin card such as a micro SD (Secure Digital Memory) card.

In recent years, with the thinning of cards, card connectors have been required to be thinner. In the card connector, a resin case is used in order to electrically separate a plurality of terminals, and the thickness of the bottom wall of the resin case can be reduced, whereby the card connector can be made thinner. Such a resin-made outer casing is formed by injecting and melting a molten synthetic resin into a mold, but if a thin wall is to be formed, since the resin is solidified before being completely expanded in the mold, it is difficult to form a thin outer casing. .

Further, even if the bottom wall of the outer casing is formed by a resin using a resin, sufficient strength cannot be obtained, and for example, there is a problem that the outer casing is easily deformed when reflow is performed. As a card connector for solving this problem, a connector in which the entire bottom wall of the outer casing is formed of a thin metal plate is known (for example, see Patent Document 1). The card connector is assembled by disposing a resin block holding a plurality of connection terminals on a metal base plate of the outer casing, thereby ensuring sufficient strength and achieving a reduction in thickness.

Thereby, the number of components does not increase, and assembly can be simplified to reduce the manufacturing cost. Further, when the size of the entire card connector in the thickness direction is defined by the sliding member or the locking mechanism, since the metal plate is embedded in the sliding region of the sliding member, the strength can be ensured by using a thin metal plate. The card connector is made thinner. Further, when the sliding member is pressed toward the bottom wall side of the outer casing by the discharge spring and simultaneously urged in the discharge direction, since the sliding member is pressed by the metal plate, deformation at the time of reflow can be prevented.

Further, in the above card connector, the lock mechanism includes a cam groove formed in the sliding member or the outer casing, and a pin sliding in the cam groove, and has a cam groove according to the cam groove A discharge structure for switching the locking and unlocking of the sliding member with the sliding position of the pin.

According to this configuration, the sliding member has a thickness capable of forming the cam groove, and the card connector for securing the accommodation space of the pin can be made thinner while ensuring strength.

Further, in the above card connector, the present invention is characterized in that the metal plate includes a ground connection portion.

According to this configuration, static electricity generated by sliding contact between the sliding member and the metal plate can be removed by grounding via the ground connection portion. Further, when the biasing spring comes into contact with the metal plate, the static electricity generated by the biasing spring can be eliminated.

Further, in the card connector of the present invention, the present invention is characterized in that an extension portion is embedded in a bottom wall of the outer casing, and the extension portion is an area passing between the connection terminal and the insertion port from the metal plate. It extends to the ground connection.

According to this configuration, the noise from the outside of the insertion port or the like can be reduced by the extension portion, and the signal transmission and reception between the card connector and the card can be stably performed via the connection terminal.

Further, in the card connector of the present invention, the extension portion includes a welded portion that is welded to an insertion opening side of the outer casing.

According to this configuration, by welding the welded portion, the strength of the insertion port side of the card connector can be improved to prevent warpage of the card connector.

Further, in the card connector of the present invention, the extension portion has a contact member that contacts the card inserted from the insertion port on the insertion opening side of the casing.

According to this configuration, when the card is inserted, the card-side card of the case is connected to the contact member, and the static electricity carried by the card can be removed via the ground connection portion to prevent the card from malfunctioning.

Further, in the above-described card connector, the present invention is characterized in that the extension portion, the connection terminal, and a switch for detecting attachment of the card are disposed in the housing direction, the extension portion and the connection terminal. And the above switches are divided by resin.

According to this configuration, since the extension portion, the connection terminal, and the switch are electrically divided by the resin, it is possible to prevent electrical malfunction of the card connector.

According to the present invention, in the card connector including the structure in which the card is inserted and removed via the sliding member, it is possible to ensure sufficient strength with an inexpensive configuration and at the same time achieve a reduction in thickness.

In the card connector to which the present invention is applied, it is required to be thinner as the card is made thinner. As such a card connector, a card connector including a push-push type discharge structure as a structure for inserting and removing a card via a slide member is known. The card connector has a sliding member that slides together with the card in the insertion/discharge direction of the card, and determines the insertion position of the card via the sliding member by sliding the pin in the card cam groove formed in the sliding member, Discharge position.

The push-push card connector has a structure in which a cam groove is formed in either the sliding member or the outer casing, and one end of the pin is engaged with the wall of the cam groove to be selectively locked, so that the other end of the pin supports the shaft. Another member that is not provided with a cam groove. In order to be fixed via a pin that is erected on the sliding member and the outer casing, a space for accommodating the pin is required in the sliding member so that the pin is not pulled out. Further, in the case where the cam groove is provided on the sliding member, it is necessary to provide the sliding member with a thickness capable of forming a cam groove having a step. Therefore, the size in the thickness direction is set in accordance with the discharge structure. Therefore, when the push-push card connector is made thinner, it is important that the thickness of the sliding region where the sliding member slides is formed thinner at the bottom wall of the outer casing.

Further, in a state where one of the sliding members is pressed toward the bottom wall side of the casing by the discharge spring, the sliding member is biased toward the discharge direction. In this case, since the sliding member is pressed, the portion of the bottom wall of the outer casing that is in sliding contact with the slider is easily deformed when reflowing is performed, so that it is necessary to secure sufficient strength in the portion. The main purpose of the present invention is to provide a card connector having a push-push discharge structure in which a thin metal plate constitutes a portion of a bottom wall of the outer casing that is in sliding contact with the slider, thereby ensuring sufficient strength and at the same time achieving thinning. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, the case where the present invention is applied to a card connector for a micro SD card will be described below. However, the application of the card connector of the present embodiment is not limited thereto, and can be appropriately changed.

First, a card to be mounted will be described before explaining the card connector according to the embodiment of the present invention. Fig. 6 is a plan view showing a card according to an embodiment of the present invention, wherein (a) is a plan view and (b) is a side view.

As shown in FIGS. 6(a) and 6(b), the card 46 is a so-called micro SD card and is formed in a substantially rectangular shape in plan view. One side of the card 46 is formed in a stepped shape in which the substantially half of the end side before the insertion direction is narrower than the width of the substantially half of the rear end side. Further, a notch portion 47 is formed in a part of one side portion of the card 46, and an engaging portion 48 is formed, and the engaging portion 48 is engaged with a sliding member 6 to be described later by the notch portion 47. Further, the card 46 has a substantially constant thickness from the front end portion to the rear end portion, and is formed in a stepped shape in which the thickness is increased at the rear end portion.

The thickness of the front end portion of the card 46 is formed to be insertable into the insertion opening 4 of the card connector 1, and the thickness of the rear end portion of the card 46 is formed so as not to be inserted into the insertion opening 4 of the card connector 1. Therefore, the card 46 can be attached to the card connector 1 only when inserted from the front end side, thereby preventing erroneous insertion of the card 46. Further, a plurality of pads (not shown) that are in contact with the plurality of connection terminals 11 of the card connector 1 are provided on the back surface of the front end side of the card 46.

Next, the overall configuration of the card connector will be described with reference to Figs. 1 and 2 . Fig. 1 is a perspective view of a card connector according to an embodiment of the present invention. Fig. 2 is an exploded perspective view showing the card connector of the embodiment of the present invention.

As shown in FIG. 1 and FIG. 2, the card connector 1 of the present embodiment includes a casing 2 made of a synthetic resin having an upper surface and a front surface open, and an opening which is attached to the upper surface of the casing 2 to form a mounting space for the card. The cover 3 made of metal, the outer casing 2 and the cover 3 are combined to form a box-like body having the insertion opening 4. A plurality of connection terminals 11 are provided in a central portion of the bottom wall 2a of the outer casing 2. Each of the connection terminals 11 provided on the bottom wall 2a extends from the central portion of the bottom wall 2a toward the inner wall 2b.

A switch 5 for mounting the card 46 is provided on the inner wall 2b of the outer casing 2. The switch 5 has a spring portion 13 that is bent toward the insertion port 4 side from the side of the inner wall 2b, and a switch head portion 14 that is provided at the free end of the spring portion 13. The movable contact portion connected to the spring portion 13 is exposed on the lower surface of the switch head portion 14, and the movable contact portion is configured to be separable or in contact with the fixed contact portion 15 provided on the bottom wall 2a.

When the switch 5 is pushed in toward the inner wall 2b side by the insertion of the card 46, the switch head portion 14 covers the fixed contact portion 15, and the mounting of the card 46 is detected. At this time, since the fixed contact portion 15 is inclined so as to become higher toward the inner wall 2b side from the insertion port 4 side, the fixed contact portion 15 and the movable contact are fixed as the switch 5 is pressed toward the inner wall 2b side. The contact between the departments has improved.

A sliding member 6 made of synthetic resin that can slide along the side wall 2c and a spiral discharge spring 7 that expands and contracts with sliding of the sliding member 6 are provided on one side wall 2c of the outer casing 2. One end of the discharge spring 7 abuts against the inner wall 2b, and the other end abuts against the sliding member 6, and urges the sliding member 6 in the discharge direction. Further, on the bottom wall 2a of the outer casing 2, a guide wall 2e is provided which protrudes slightly from the upper surface, and the guide wall 2e guides the sliding member 6 together with the side wall 2c in the insertion direction.

A metal plate 21 is provided in a sliding region of the sliding member 6 formed by the guide wall 2e and the side wall 2c. The metal plate 21 extends in the sliding direction of the sliding member 6, so that the rigidity against deflection in the insertion direction of the card connector 1 is improved. The metal plate 21 is formed to be thinner than the thickness of the bottom wall 2a of the outer casing 2, and supports the sliding member 6 at a position lower than the portion of the bottom wall 2a into which the card 46 is inserted and is slidable. That is, the thickness of the metal plate 21 is formed thinner than the thickness of the bottom wall 2a of the outer casing 2, and a sliding region is formed at a position lower than the height of the inserted card 46. Therefore, the thickness of the portion of the entire height of the sliding member 6 into which the card 46 is inserted can be reduced, and the sliding area of the sliding member 6 can be reduced. The metal plate 21 can be fitted and fitted so as to close the opening of the outer casing 2 surrounded by the guide wall 2e and the side wall 2c, and the metal plate 21 can be integrally embedded by insert molding when the synthetic resin outer casing 2 is formed.

Moreover, since the frictional resistance of the metal plate 21 is lower than that of the resin material, the metal plate 21 can smoothly slide the sliding member 6 as compared with the configuration in which the sliding member 6 slides on the resin case. Further, even when the sliding member 6 is biased in a state where the discharge spring 7 is pressed toward the bottom wall 2a side of the outer casing 2, since the strength of the sliding region is ensured by the metal plate 21, deformation during reflow can be prevented. .

The slide member 6 is configured to be slidable in the insertion and discharge directions while being biased by the discharge spring 7. A cam groove 23 is formed on the front end side of the sliding member 6, and the position of the sliding member 6 is defined by the cam groove 23 and the pin 24 provided on the inner wall 2b. The pin 24 extends along the side wall 2c, and both ends are bent substantially at right angles toward the bottom wall 2a. One end of the pin 24 is rotatably supported by the inner wall 2b, and the other end slides on the cam groove 23 of the sliding member 6.

The cam groove 23 is a so-called circulation type cam groove called a heart type cam, and has a plurality of height differences and inclinations to form a heart-shaped ring shape in a plan view, and the other end of the pin 24 as the sliding member 6 slides Slide in one direction. When the sliding member 6 is pressed into the mounting position near the inner wall 2b, the other end of the pin 24 is locked to the locking portion of the cam groove 23 to restrict the reset of the sliding member 6 due to the urging force of the discharge spring 7. When the sliding member 6 is further pressed from this state, the locked state of the pin 24 and the cam groove 23 is released, and the sliding member 6 is reset by the biasing force of the discharge spring 7. Thus, the pin 24 and the cam groove 23 have a retaining function at the mounting position of the sliding member 6.

At this time, since the sliding member 6 has a thickness capable of forming the cam groove 23 and a receiving space for the pin 24 formed above the sliding member 6, the design of the card connector 1 requires the maximum height of the portion. . Therefore, the card connector 1 is designed to have a thickness based on the sliding area. As described above, since the sliding member 6 can be slid at a lower position by the metal plate 21, the card connector 1 can be made thinner.

Further, an engagement recess 26 that engages with the engagement portion 48 of the card 46 is formed on the rear end side of the slide member 6. The engaging member 48 of the card 46 engages with the engaging recess 26, and the sliding member 6 slides integrally with the card 46. Further, the engaging recessed portion 26 has a claw portion 27 that slightly protrudes toward the center of the outer casing 2. When the engaging portion 48 is engaged with the engaging recessed portion 26, the claw portion 27 enters the notch portion 47 of the card 46, and the falling of the card 46 in the discharge direction is suppressed.

The cover 3 is formed by bending a metallic plate, and a pin pressing portion 31 of the pressing pin 24 is formed on one side of the upper surface. The pin pressing portion 31 is a cantilever spring that is cut toward the side of the bottom wall 2a, and presses the intermediate portion of the pin 24 downward, and presses the other end of the pin 24 against the cam groove 23. Further, a pair of brake pads 32 for preventing the flying out of the card 46 are formed on substantially the half of the insertion opening 4 side of the upper surface of the cover 3. The pair of brake pads 32 are cantilever springs slightly cut toward the side of the bottom wall 2a, and are in contact with the upper surface of the card 46 to suppress the flying out of the card 46 when it is discharged.

Referring to Figures 3 and 4, the outer casing and the conductor portion embedded in the outer casing will be described in detail. Fig. 3 is a plan view of the outer casing of the embodiment of the present invention. Fig. 4 is a plan view showing a conductor portion embedded in a casing according to an embodiment of the present invention.

As shown in FIG. 3, an opening is formed in the outer casing 2 corresponding to the sliding region, and the substantially rectangular metal plate 21 is buried in a state in which the opening is exposed. A plurality of curved portions 34 bent upward are formed at both end portions in the width direction of the metal plate 21, and the plurality of curved portions 34 are arranged to be longitudinally partitioned between the insertion port 4 side and the inner wall 2b (refer to the figure). 4). The plurality of curved portions 34 are embedded in the side wall 2c and in the guide wall 2e to reinforce the side wall 2c and the guide wall 2e formed around the opening of the outer casing 2. When it is buried, it can be manufactured by insert molding in which the molten synthetic resin is injection molded and filled into the mold while holding the metal plate 21 in a mold attached to the injection molding machine. The synthetic resin is cured to integrally form the metal plate 21 and the outer casing 2.

A substantially half portion of the side wall 2c on the side of the insertion port 4 is formed with a recessed portion 35 that allows the sliding of the sliding member 6 to be concave. The escaping portion 35 allows the sliding of the sliding member 6, thereby allowing the card 46 at the discharge position to be pulled out, and the card 46 at the mounting position is prohibited from being pulled out. Further, the details of the shaking operation of the sliding member 6 will be described below.

The inner wall 2b of the outer casing 2 is provided with a convex portion 36 that supports one end of the discharge spring 7. An opening 37 is formed below the convex portion 36 so as to avoid the metal plate 21. A mold for forming the convex portion 36 on the inner wall 2b when the outer casing 2 is formed is provided in the opening 37.

Further, as shown in FIG. 3 and FIG. 4, the first extension portion 41 extending in the width direction from the insertion port 4 side of the metal plate 21 and the front end side toward the inner wall from the first extension portion 41 are embedded in the outer casing 2. The second extension 42 extending from 2b. The first extension portion 41 is disposed in a region between the plurality of connection terminals 11 and the insertion port 4, and the second extension portion 42 is disposed on a side of the plurality of connection terminals 11.

In other words, the first and second extending portions 41 and 42 extend in such a manner as to surround the plurality of connection terminals 11 together with the metal plate 21. According to this configuration, the rigidity of the card connector 1 in the insertion direction and the width direction can be improved, and the influence of the noise entering from the outside such as the insertion port 4 side can be reduced, and the card connector 1 and the card 46 can be made. The signal transmission and reception via a plurality of connection terminals 11 is stable.

A pair of welded portions 43 are provided in the first extension portion 41, and the pair of welded portions 43 protrude toward the opening 39 formed on the insertion port 4 side of the outer casing 2 from the middle in the extending direction. The pair of soldering portions 43 are connected to the ground of the circuit board provided on the circuit board (not shown) on which the card connector 1 is mounted to form a ground connection portion, and the static electricity generated in the card connector 1 is removed to the ground. Further, by the welding of the welded portion 43, the rigidity against deflection in the width direction of the insertion opening 4 side of the card connector 1 is improved, and the warpage of the card connector 1 can be prevented.

Further, the first extension portion 41 is provided with a pair of contact members 44 that are exposed with respect to the insertion port 4 and that extend toward the insertion port 4 from a portion in the extending direction. When the card 46 is inserted, the pair of contacts 44 are in contact with the front end portion of the card 46 together with the first extension portion 41 extending in the width direction, and the static electricity carried on the card 46 is grounded via the solder portion 43 (ground connection portion). exclude. In this case, since the card 46 is de-energized in two stages by the pair of contacts 44 and the first extension portion 41, a high power-removing effect can be obtained. Thereby, it is possible to prevent the malfunction of the card 46 caused by the static electricity carried by the card 46.

Further, since the first extension portion 41 connects the metal plate 21 and the welded portion 43 (the ground connection portion), the static electricity generated between the metal plate 21 and the sliding member 6 is removed to the ground via the welded portion 43. Further, since the discharge spring 7 is also in contact with the metal plate 21, the static electricity generated by the expansion and contraction of the discharge spring 7 is also removed to the ground via the welded portion 43. In this way, the static electricity carried by the card connector 1 is removed to the ground, and the malfunction of the card 46 caused by the static electricity carried by the card connector 1 can be prevented.

In the casing 2 thus constructed, a first extension portion 41 for removing the card 46 and the card connector 1 , a plurality of connection terminals 11 connected to the pads of the card 46, and a switch 5 for detecting the mounting of the card 46 are formed. Each conductor portion is divided by an insulating resin. Therefore, since the conductor portions constituting the first extension portion 41, the connection terminal 11, and the switch 5 are electrically divided, it is possible to prevent malfunction of the electrical connector of the card.

The mounting operation of the card with respect to the card connector will be described with reference to FIG. Fig. 5 is an explanatory view showing a mounting operation of the card with respect to the card connector of the embodiment.

As shown in FIG. 5(a), when the card 46 is inserted into the card connector 1, the claw portion 27 of the slide member 6 is pressed laterally by the engaging portion 48 formed by one side of the card 46. When the claw portion 27 of the slide member 6 is pressed by the engagement portion 48 of the card 46, the slide member 6 is pivoted toward the relief portion 35 formed on the side wall 2c of the outer casing 2 with the other end of the pin 24 as a fulcrum.

When the card 46 is further pressed from the state of FIG. 5(a), the engaging portion 48 of the discharge position card 46 is engaged with the engaging recessed portion 26 of the slide member 6 as shown in FIG. 5(b). In this case, the claw portion 27 of the sliding member 6 enters the notch portion 47 of the card 46, and the pressing portion 48 of the card 46 releases the pressing portion of the claw portion 27 of the sliding member 6, so that the sliding member 6 is pinned The other end is a fulcrum, and the avoidance portion 35 is swung to the original position.

At the discharge position, since the slide member 6 can be swung by the relief portion 35, the card 46 can be allowed to be pulled out. Specifically, when a force is applied to the card 46 in the discharge direction, the slide member 6 is swung toward the relief portion 35 with the other end of the pin 24 as a fulcrum. Due to the shaking of the sliding member 6, the sliding member 6 is detached from the notch portion 47 of the card 46, allowing the card 46 to be pulled out.

If the card 46 is further pressed from the state shown in Fig. 5(b), as shown in Fig. 5(c), the other end of the pin 24 is locked to the locking portion of the cam groove 23, and the card 46 is together with the sliding member 6. Keep in the installation position. At this time, the sliding member 6 is guided in the insertion direction in a state where the side wall 2c and the guide wall 2e are restricted from shaking. When the card 46 is inserted into the mounting position, the switch 5 is pressed in, thereby detecting the installation of the card 46.

In this mounting position, the sliding of the sliding member 6 is restricted by the side wall 2c and the guiding wall 2e, so that the pulling out of the card 46 is prohibited. Specifically, even if a force is applied to the card 46 in the discharge direction, since the sliding of the slide member 6 is restricted, the claw portion 27 is not detached from the notch portion 47 of the card 46, and the removal of the card 46 is prohibited. In this case, since the side wall 2c is reinforced by the plurality of curved portions 34 of the metal plate 21, the deformation of the side wall 2c can be reliably suppressed. Therefore, the shaking of the sliding member 6 is reliably restricted, and the forced pulling of the card 46 at the mounting position is prohibited.

Then, when the card 46 is further pressed from the state of Fig. 5(c), the locked state of the pin 24 and the cam groove 23 is released, and the slide member 6 is pressed back to the discharge position by the discharge spring 7.

As described above, in the card connector 1 of the present embodiment, since the connection terminal 11 is embedded in the bottom wall 2a of the resin case 2, and the metal plate 21 is partially embedded, even when the case 2 is made thinner. It is also possible to increase the strength of the outer casing 2 without making the connection terminals 11 different. Therefore, the number of parts is not increased, and assembly can be simplified to reduce the manufacturing cost. Further, when the size of the entire card connector 1 in the thickness direction is defined by the sliding member 6 or the pin 24, since the metal plate 21 is embedded in the sliding region of the sliding member 6, the card can be connected while ensuring strength. The device 1 is thinned.

Furthermore, in the above embodiment, the present invention is applied to a card connector corresponding to a micro SD card, but the configuration is not limited thereto. It can also be applied to a card connector that can correspond to a card other than a micro SD card.

Further, in the above embodiment, the present invention is applied to a card connector corresponding to a card, but the configuration is not limited thereto. It is also applicable to a combination card connector that can correspond to two or more types of cards, or a card connector that can correspond to three or more types of cards.

Further, in the above embodiment, the locking mechanism is constituted by the cam groove of the sliding member and the pin, but the configuration is not limited thereto. It is also possible to provide a configuration in which the sliding member is provided with a pin and a cam groove is provided in the outer casing. Any configuration may be adopted as long as it can lock the sliding member to the mounting position of the card.

However, the configuration is not limited thereto. The sliding member may be biased in the discharge direction by the discharge spring, and the sliding member may not be pressed.

Further, in the above embodiment, the configuration is such that the extension portion is provided on the metal plate, but the configuration is not limited thereto. It suffices that the metal plate can secure sufficient strength and at the same time achieve a thinner configuration, and the extension portion can be omitted.

Further, in the above embodiment, the contact is provided in the extension portion, and the card is de-energized by the extension portion and the contact member, but the configuration is not limited thereto. It may be configured to de-energize the card only by the extension portion without providing the contact member, or may be configured to remove only the contact member and de-energize the card only by the contact member.

Further, in the above embodiment, the metal plate is connected to the ground via the extension portion, but the configuration is not limited thereto. As long as the metal plate is connected to the ground, for example, the metal plate may be directly connected to the ground.
