Description

  The present invention relates to a card connector, and more particularly to a card connector compatible with a thin card such as a micro SD card.

  In recent years, with a reduction in the thickness of a card, a reduction in the thickness of a card connector has been demanded. Generally, in a card connector, a resinous housing is used in order to electrically separate and arrange a plurality of terminals. By reducing the thickness of the bottom wall of the resin housing, the card connector is used. The thickness is reduced. Such a resin housing is molded by injecting a molten synthetic resin into a mold, filling it and solidifying it, but if you try to make it thin, it will harden before the resin spreads in the mold. It has been difficult to mold a thin housing.

  Moreover, even if the bottom wall of the housing can be formed thin with resin, sufficient strength cannot be obtained, and there is a problem that the housing is easily deformed during reflow, for example. As a card connector that solves this problem, a connector in which the entire bottom wall of the housing is formed of a thin metal plate is known (for example, see Patent Document 1). This card connector achieves thinning while ensuring sufficient strength by assembling a resin block holding a plurality of connection terminals on a metal bottom plate of the housing.

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

  First, before explaining the card connector according to the embodiment of the present invention, a card to be mounted will be explained. 6A and 6B are plan views of the card according to the embodiment of the present invention, in which FIG. 6A is a top view and FIG. 6B is a side view.

  As shown in FIGS. 6A and 6B, the card 46 is a so-called micro SD card, and is formed in a substantially rectangular shape when viewed from above. One side portion of the card 46 is formed in a step shape in which the substantially half portion on the front end side in the insertion direction is narrower than the substantially half portion on the rear end side in plan view. Further, a notch 47 is partially formed on one side of the card 46, and an engaging portion 48 that engages with a slide member 6 described later is formed by the notch 47. The card 46 has a substantially constant thickness from the front end portion to the vicinity of the rear end portion, and is formed in a step shape in which the thickness increases at the rear end portion.

  The thickness of the front end portion of the card 46 is formed so as to be inserted into the insertion port 4 of the card connector 1, and the thickness of the rear end portion of the card 46 is not large enough to be inserted into the insertion port 4 of the card connector 1. Is formed. Therefore, since the card 46 is attached to the card connector 1 only when inserted from the front end side, erroneous insertion of the card 46 is prevented. A plurality of pads (not shown) that come into contact with the plurality of connection terminals 11 of the card connector 1 are provided on the back surface of the card 46 on the front end side.

  Next, the overall configuration of the card connector will be described with reference to FIGS. 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 of the card connector according to the embodiment of the present invention.

  As shown in FIGS. 1 and 2, the card connector 1 according to the present embodiment is mounted on a synthetic resin housing 2 whose upper surface and front surface are opened, and an opening on the upper surface of the housing 2 to mount a card. The housing 2 and the cover 3 are combined to form a box-like body having the insertion port 4. A plurality of connection terminals 11 are provided at the central portion of the bottom wall 2 a of the housing 2. Each connection terminal 11 provided on the bottom wall 2a extends from the central portion of the bottom wall 2a toward the back wall 2b.

  On the back wall 2b of the housing 2, a switch 5 for detecting the mounting of the card 46 is provided. The switch 5 includes a spring portion 13 that is bent from the back wall 2 b side to the insertion port 4 side, and a switch head portion 14 that is provided at the free end of the spring portion 13. A 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 detachable from a fixed contact portion 15 provided on the bottom wall 2a.

  When the switch 5 is pushed into the back wall 2b side by insertion of the card 46, the switch head 14 rides on the fixed contact 15 and detects the mounting of the card 46. In this case, since the fixed contact portion 15 is inclined so as to increase from the insertion port 4 side toward the back wall 2b side, as the switch 5 is pushed into the back wall 2b side, The contact property is improved.

  One side wall 2c of the housing 2 is provided with a synthetic resin slide member 6 slidable along the side wall 2c and a coiled discharge spring 7 which expands and contracts as the slide member 6 slides. One end of the discharge spring 7 is in contact with the back wall 2b and the other end is in contact with the slide member 6, and urges the slide member 6 in the discharge direction. A guide wall 2e for guiding the slide member 6 in the insertion direction together with the side wall 2c is provided on the bottom wall 2a of the housing 2 so as to slightly protrude from the upper surface.

  A metal plate 21 is provided in the slide region of the slide 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 and enhances rigidity against bending in the insertion direction of the card connector 1. The metal plate 21 is formed to be thinner than the thickness of the bottom wall 2a of the housing 2, and allows the slide member 6 to slide at a position lower than the portion of the bottom wall 2a where the card 46 is inserted. The metal plate 21 can be fitted and attached so as to close the opening of the housing 2 surrounded by the guide wall 2e and the side wall 2c, but when forming the synthetic resin housing 2, the metal plate 21 is insert-molded. It is possible to embed it integrally.

  Further, since the metal plate 21 has a lower frictional resistance than the resin material, the slide member 6 can be smoothly slid as compared with the configuration in which the metal plate 21 is slid onto the slide member 6. Further, even when the slide member 6 is urged while being pushed down to the bottom wall 2 a side of the housing 2 by the discharge spring 7, the strength of the slide region is ensured by the metal plate 21. Can be prevented.

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

  The heart cam groove 23 is formed in a heart-shaped annular shape having a plurality of steps and slopes, and slides the other end of the latch pin 24 in one direction in accordance with the slide of the slide member 6. When the slide member 6 is pushed into the mounting position in the vicinity of the back wall 2b, the other end of the latch pin 24 is locked to the locking portion of the heart cam groove 23, and the return of the slide member 6 due to the bias of the discharge spring 7 is restricted. . When the slide member 6 is further pushed in from this state, the latched state of the latch pin 24 and the heart cam groove 23 is released, and the slide member 6 is returned by the urging of the discharge spring 7. Thus, the latch pin 24 and the heart cam groove 23 have a holding function at the mounting position of the slide member 6.

  In this case, the slide member 6 has a thickness that allows the heart cam groove 23 to be formed, and an accommodation space for the latch pin 24 is formed above the slide member 6. Height is required. For this reason, the thickness of the card connector 1 is designed on the basis of the slide area. However, as described above, the slide member 6 is slid at a low position by the metal plate 21, so that the card connector 1 is thinned. It becomes possible.

  Further, an engagement recess 26 that is engaged with the engagement portion 48 of the card 46 is formed on the rear end side of the slide member 6. When the engaging portion 48 of the card 46 is engaged with the engaging recess 26, the slide member 6 is slid integrally with the card 46. Further, the engagement recess 26 has a claw portion 27 that slightly protrudes toward the center of the housing 2. When the engaging portion 48 is engaged with the engaging concave portion 26, the claw portion 27 enters the cutout portion 47 of the card 46 and suppresses the card 46 from being removed in the ejection direction.

  The cover 3 is formed by bending a metallic plate material, and a pin presser 31 for pressing the latch pin 24 is formed on one side of the upper surface. The pin presser 31 is a cantilever spring cut and raised toward the bottom wall 2 a, pressing the intermediate portion of the latch pin 24 downward and pressing the other end of the latch pin 24 against the heart cam groove 23. A pair of braking pieces 32 for preventing the card 46 from popping out are formed in a substantially half portion of the upper surface of the cover 3 on the insertion port 4 side. The pair of braking pieces 32 are cantilever springs that are slightly cut and raised toward the bottom wall 2 a, and come into contact with the upper surface of the card 46 to suppress the jumping out of the card 46 when ejected.

  With reference to FIGS. 3 and 4, the housing and the conductor portion embedded in the housing will be described in detail. FIG. 3 is a top view of the housing according to the embodiment of the present invention. FIG. 4 is a top view of the conductor portion embedded in the housing according to the embodiment of the present invention.

  As shown in FIG. 3, the housing 2 has an opening corresponding to the slide region, and the substantially rectangular metal plate 21 is buried in the opening. At both ends of the metal plate 21 in the short direction, a plurality of bent portions 34 bent upward are aligned and formed so as to cut vertically between the insertion port 4 side and the back wall 2b (see FIG. 4). The plurality of bent portions 34 are embedded in the side wall 2c and the guide wall 2e, and reinforce the side wall 2c and the guide wall 2e formed around the opening of the housing 2. In embedding, the metal plate 21 is held in a mold attached to an injection molding machine, and a molten synthetic resin is injection-molded, filled in the mold, and solidified to be integrated with the housing 2. It can be manufactured by insert molding.

  A concave relief portion 35 that allows the slide member 6 to swing is formed in a substantially half portion of the side wall 2c on the insertion port 4 side. By allowing the slide member 6 to swing by the escape portion 35, the card 46 is allowed to be extracted at the ejecting position, and the card 46 is not allowed to be extracted from the mounting position. The details of the swinging motion of the slide member 6 will be described later.

  A convex portion 36 that supports one end of the discharge spring 7 is provided on the back wall 2 b of the housing 2. An opening 37 is formed below the convex portion 36 so as to avoid the metal plate 21.

  As shown in FIGS. 3 and 4, the housing 2 includes a first extension 41 extending in the width direction from the insertion port 4 side of the metal plate 21, and a rear wall from the distal end side of the first extension 41. A second extension 42 extending toward 2b is embedded. The first extension 41 is disposed in a region between the plurality of connection terminals 11 and the insertion port 4, and the second extension 42 is disposed on the side of the plurality of connection terminals 11.

  That is, the first and second extending portions 41 and 42, together with the metal plate 21, extend so as to surround three sides of the plurality of connection terminals 11. With this configuration, the rigidity against bending in the insertion direction and the width direction of the card connector 1 is increased, noise from the insertion port 4 side is reduced, and the card connector 1 and the card 46 are connected via the plurality of connection terminals 11. It is possible to stabilize signal exchange.

  The first extension portion 41 is provided with a pair of soldering portions 43 that project from an intermediate portion in the extending direction toward an opening 39 formed on the insertion port 4 side of the housing 2. The pair of soldering portions 43 are connected to the ground and allow static electricity generated in the card connector 1 to escape to the ground. Further, by soldering the soldering portion 43, it is possible to increase the rigidity against bending in the width direction on the insertion port 4 side of the card connector 1 and to prevent the card connector 1 from warping.

  The first extension 41 is exposed to the insertion port 4, and a pair of contacts 44 extending from the middle part in the extending direction toward the insertion port 4 are provided. When the card 46 is inserted, the pair of contacts 44 come into 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 charged in the card 46 is passed through the soldering portion 43. Escape to the ground. In this case, since the card 46 is neutralized in two stages by the pair of contacts 44 and the first extension portion 41, a high static elimination effect can be obtained. Therefore, malfunction of the card 46 due to static electricity charged on the card 46 can be prevented.

  Furthermore, since the first extension 41 connects the metal plate 21 and the ground, the static electricity generated between the metal plate 21 and the slide member 6 is released to the ground via the soldering portion 43. Yes. Further, since the discharge spring 7 is also in contact with the metal plate 21, static electricity generated by the expansion and contraction of the discharge spring 7 is released to the ground via the soldering portion 43. As described above, since static electricity charged in the card connector 1 is also released to the ground, malfunction of the card 46 due to the static electricity charged in the card connector 1 can be prevented.

  In the housing 2 configured as described above, the first extension 41 for removing electricity from the card 46 and the card connector 1, the plurality of connection terminals 11 connected to the pads of the card 46, and the switch 5 for detecting the attachment of the card 46 are provided. Each conductor part which comprises is divided with insulating resin. Accordingly, the first extending portion 41, the connection terminal 11 and the conductor portion constituting the switch 5 are electrically separated, so that an electrical malfunction of the card connector can be prevented.
