Description

  The present invention relates to a card connector. In particular, the present invention relates to a card connector structure including a switch for detecting that a card-like recording medium such as a memory card is attached to the connector.

  For example, a memory card such as an SD (Secure Digital) card employs a flash memory as a storage medium. A memory card is very small and consumes little electric power for reading and writing data. For example, it is widely used as a recording medium for portable information devices such as mobile phones with cameras and PDAs (Personal Digital Assistance).

  In general, a card connector to which such a card is mounted is provided with a card detection switch and a write protect detection switch. The card detection switch has a function of detecting that a card is inserted. The write protect detection switch has a function of detecting whether data is allowed to be written on the card.

  The detection switch in the card connector generally includes a pair of switch members each composed of a contact plate and a contacted plate. The contact plate is provided in a card receiving portion of a housing constituting the card connector, and is displaced by a card inserted into the card receiving portion. The contacted plate is provided in the card receiving portion and is brought into contact with the displaced contact plate.

In a card connector provided with a card detection switch and a write protect detection switch, a detection switch has been invented that enables cost reduction by sharing a contact plate and a contacted plate (for example, Patent Document 1). reference).

  FIG. 12 is an enlarged perspective view showing two switch members constituting the detection switch of the first embodiment of Patent Document 1. FIG. 12 of the present application corresponds to FIG. FIG. 13 is an enlarged side view of contact portions of two switch members constituting the detection switch of the first embodiment. FIG. 13 of the present application corresponds to FIG.

  In FIG. 12, the detection switch 80 is composed of a first switch member 81a and a second switch member 81b. The first switch member 81a and the second switch member 81b are arranged in a line in the same direction as the insertion direction of the SD card C. The front end portion of the first switch member 81a and the rear end portion of the second switch member 81b are installed so as to overlap each other.

  In FIG. 12, the front end portion of the first switch member 81a is provided with a slope portion 82 that is bent or curved in an arc shape so as to protrude toward the SD card C side. The slope 82 faces the tip corner C1 of the SD card C. On the other hand, the rear end portion of the second switch member 81b is provided with an inclined surface portion 83 that is bent or curved toward an obliquely downward direction with respect to the insertion direction D1 of the SD card C (see FIG. 9).

  In FIG. 12 or FIG. 13, the slope portion 83 of the second switch member 81b and the slope portion 82 of the first switch member 81a are located so as to intersect the insertion direction D1 of the SD card C. The side edge 82a of the slope portion 82 and the side edge 83a of the slope portion 83 are opposed to each other via a gap. The side edge 82 a forms a first contact 84, the side edge 83 a forms a second contact 85, and the first contact 84 and the second contact 85 constitute a detection switch 80. In addition, the slope part 86 continuing to the slope part 82 of the first switch member 81a can enter below the flat surface part 87 continuing to the slope part 83 of the second switch member 81b.

  In FIG. 12, when the SD card C is inserted in the direction of the arrow D1, the tip corner portion C1 comes into contact with the slope portion 82, and the front end portion of the first switch member 81a is displaced outward in the direction of the arrow D2. Then, the first contact 84 engages with the second contact 85. Therefore, the detection switch 80 is turned on, and insertion of the SD card C can be detected.

  In FIG. 12, when the SD card C is further inserted, the slope 82 is displaced in the direction of the arrow D2, and the slope 83 is displaced in the direction of the arrow D3. Further, the engaging portion of the first contact 84 and the second contact 85 moves from the slope portion 83 toward the flat surface portion 87. In FIG. 13, the displaced slope portion 83 is indicated by an imaginary line (two-dot chain line).

  In FIG. 12, the rear end portion of the first switch member 81a has the same shape as the rear end portion of the second switch member 81b. The front end portion of the second switch member 81b has the same shape as the front end portion of the first switch member 81a. Then, the second switch member 81b and the third switch are arranged in a row in front of the second switch member 81b by arranging a third switch member 81c (not shown) in which the front end portion of the first switch member 81a is removed. A combination with the member 81c can be used as a card detection switch. Further, the detection switch 80 shown in FIG. 12 can be a write protect detection switch.

  As described above, the detection switch disclosed in Patent Document 1 shares the same shape with at least two switch members provided in the housing of the card connector, so that the manufacturing cost of the card connector can be reduced. .

  As disclosed in Patent Document 1, in the card detection switch provided in the card connector, the contact of the contact plate displaced by the inserted card and the contact of the contacted plate contacted by the displaced contact plate are close to each other. Has been placed. When the card is loaded, the tip of the contact plate immediately contacts the contacted plate, and the card loading state is detected.

  However, when vibration or impact is applied to an electronic device having such a card detection switch, the contact force of the contact plate is applied to the contact point of the contact plate even though the card is not installed. Can come in contact. There is a so-called false detection problem.

  If the contact point of the contact plate is sufficiently spaced from the contact point of the contacted plate so that the contact plate does not easily come into contact with the contacted plate due to vibration or impact, the outer shape of the card connector becomes undesirably large. In addition, the amount of bending of the contact plate is increased, which may affect the life of the contact plate. Although the contact of the contact plate is located close to the contact of the contacted plate, there is a need for a card connector having a card detection switch that does not easily contact the contact of the contacted plate due to vibration or impact. It is done. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a card connector including a card detection switch in which a contact plate does not easily come into contact with a contacted plate due to vibration or impact.

  The present inventor is a card connector including a card detection switch composed of a contact plate and a contacted plate, and a tip portion having a contact is elastically deformed in the thickness direction by the inserted card and inserted. The contact plate was configured to be elastically deformed by the card in a direction substantially perpendicular to the plate thickness direction. When the card is not attached to the connector, only when the strong inertial force that elastically deforms in the plate thickness direction and the strong inertial force that elastically deforms in the direction substantially orthogonal to the plate thickness direction overlap, By placing the contact plate and the contact plate so that they come into contact with each other, it is found that the contact plate does not easily come into contact with the contact plate due to vibration or impact. It came to invent the connector for cards provided with a detection switch.

  (1) A card connector comprising a housing from which a card is inserted and removed, a contact plate that is displaced by the inserted card, and a card detection switch that is a contacted plate that contacts the displaced contact plate.

When the contact plate comes into contact with the contacted plate, the card detection switch is turned on, and the electronic device including the card connector recognizes that the card is mounted. Then, data can be written on a card as a recording medium, or data recorded on the card can be read.

  The housing has an insulating property. The insulating housing may be a housing made of a non-conductive material, and a synthetic resin can be molded to obtain an insulating housing having a desired shape.

  The contact plate and the contacted plate may be formed by bending a developed metal plate to obtain a desired shape. The contact plate and the contacted plate are preferably conductive metal plates. For example, a copper alloy or the like is applied, but the contact plate and the contacted plate are not limited to the copper alloy.

  First, the configuration of a card connector (hereinafter abbreviated as a connector) according to the present invention will be described. 1 to 3, the connector 10 includes a plate-shaped housing 2 and a card detection switch 3 (hereinafter, abbreviated as a detection switch 3). The housing 2 has a recess 21 that forms an opening 22 into which the card 1 formed in a substantially rectangular shape is inserted and removed. The detection switch 3 includes a contact plate 31 and a contacted plate 32. The detection switch 3 is arranged on one wing of the recess 21 of the housing 2.

  In FIG. 1 or FIG. 2, the contact plate 31 includes a movable piece 311, a movable piece 312, and a contact 313. The movable piece 311 has a base end portion 31 a fixed to the bottom wall of the recess 21. The movable piece 311 has a distal end portion 31b extending from the proximal end portion 31a to the side opposite to the opening 22. In the movable piece 312, the base end portion 31c is refracted at a substantially right angle from the middle between the base end portion 31a and the tip end portion 31b. In addition, the movable piece 312 extends in an inclined manner so that the distal end portion 31d passes the distal end portion 31b and faces the distal end portion 31b on the side opposite to the opening 22. A part of the tip 31d protrudes from the contact 313.

  In FIG. 1, the contacted plate 32 has a fixed piece 321 and a contact 323. The fixed piece 321 has a base end portion 32 a fixed to the bottom wall of the recess 21. The fixed piece 321 extends in a direction in which the distal end portion 32 b is substantially orthogonal to the movable piece 311. The contact 323 is disposed in proximity to the contact 313 with the distal end 32 b of the fixed piece 321 being refracted.

  1 to 3, the tip 31b of the movable piece 311 is provided with a step portion 31e on which the tip edge 1a of the card 1 can get over (see FIG. 5).

  In FIG. 4, the housing 2 includes a pair of reinforcing tabs 61 and 62 that surround both wings. The pair of reinforcing tabs 61 and 62 have joint portions 61a and 62b that are soldered to the printed circuit board 1p. The contact plate 31 has a lead piece 314 that is soldered to the printed circuit board 1p. The to-be-contacted plate 32 is couple | bonded with one reinforcement tab 61 (refer FIG. 1).

  In FIG. 4, the housing 2 includes a plurality of cantilever contacts (hereinafter abbreviated as contacts 4). The contact 4 has a movable piece 411 and a contact 413 connected to a contact (not shown) of the card 1. The contact 4 has a lead piece 414 that is soldered to the printed circuit board 1p (see FIG. 1).

  In FIG. 3, the connector 10 includes a slider 5 for mounting the card 1. The slider 5 has a recess (not shown) for mounting the card 1. A pair of grooves 23a and 23b for movably guiding the slider 5 are provided on both wings of the housing 2. The slider 5 is regulated by the pair of grooves 23 a and 23 b and can advance and retract the card 1 to and from the housing 2.

  Next, the operation will be described while capturing the configuration of the connector 10 according to the present invention.

  In FIG. 6, the card 1 is inserted from the opening 22 of the housing 2 to the front of the step portion 31e. 7 to 10, the card 1 is indicated by a two-dot chain line (imaginary line). In FIG. 6, the contact point 313 of the contact plate 31 and the contact point 323 of the contacted plate 32 are disposed close to each other, but have a relative positional relationship that makes it difficult to contact each other. In the state shown in FIG. 6, the detection switch 3 is in an off state.

  Next, as shown in FIG. 7, when the leading edge 1a of the card 1 pushes down the step portion 31e, the movable piece 311 is bent and deformed. Further, the tip 31b is pushed down below the surface of the card 1, and the movable piece 311 is elastically deformed. At this stage, the leading edge 1a of the card 1 is not in contact with the leading end 31d (see FIG. 10). Here, as for the contact plate 31, when the movable piece 311 bends downward, the front-end | tip part 31d falls and the contact 313 displaces below. At this time, the contact point 313 and the contact point 323 are disposed at the same height, but have a relative positional relationship that makes it difficult to contact each other because there is a gap in the horizontal direction. Therefore, the detection switch 3 is in an off state in which the card 1 is not detected.

  Next, as shown in FIG. 8, when the card 1 is further inserted, the corner 1b of the card 1 pushes the tip 31b, and the movable piece 312 is bent and deformed. Further, the tip 31d is pushed by the corner 1b of the card 1, and the movable piece 312 is bent and deformed. At this stage, the tip 31d of the movable piece 312 is displaced in the lateral direction, so that the contact 313 is also displaced in the lateral direction.

  In this way, the contact 313 receives the downward displacement and the lateral displacement due to the insertion of the card 1 and comes into contact with the contact 323. And when the contact plate 31 and the to-be-contacted plate 32 contact, the detection switch 3 will be in an electrical connection state (refer FIG. 11). Further, when the card 1 is removed, the contact plate 31 is restored and the contact 313 is separated from the contact 323, so that the contact plate 31 and the contacted plate 32 are electrically disconnected. In this way, the presence or absence of the card 1 is detected.

  In the connector 10 according to the present invention, the contact 313 cannot contact the contact 323 even if a unidirectional inertial force is applied due to vibrations or shocks that cause the tip 31b to move downward. Further, the contact 313 cannot contact the contact 323 even if an inertial force that displaces the distal end portion 31 d in the lateral direction acts. The contact 323 can be contacted only when a strong inertia force that simultaneously elastically deforms the contact 313 in the downward direction and the right direction is applied. Therefore, the connector 10 according to the present invention can suppress erroneous detection of the card due to vibration or impact.

  Further, in the connector 10 according to the present invention, since the contact 323 is inclined, the contact 313 slides and comes into contact. So-called self-cleaning is possible (see FIG. 5).

  In the connector 10 according to the present invention, one of the plurality of contacts 4 may also serve as the contact plate 31. By doing so, the required number of contacts 4 can be reduced, which can contribute to a reduction in manufacturing cost.
