Description

  The present invention relates to a card connector, and more particularly to a memory card connector that is built into an electronic device such as a digital camera and can be loaded with a memory card.

  Electronic devices such as digital cameras, portable audio devices, cellular phones, and electronic copying machines have built-in memory card connectors. The electronic devices have a memory card with a built-in semiconductor memory device attached to the memory card connector. Used in the state.

  Currently, there are multiple types of memory cards, and the method of detecting the state of being inserted into the memory card connector differs depending on the type of memory card. There are a method of detecting by contacting a corresponding contact in the card connector and a method of detecting by pressing a switch provided on the side of the memory card in the memory card connector and operating the switch. Memory Stick (trademark) and Memory Stick Duo (trademark) are the former, and SD Memory Card (trademark) and MMC (Multimedia Card) (trademark) are the latter.

  Further, as shown in FIG. 1A, the SD memory card 20 has a knob 23 slidably provided between the write-inhibited position P1 and the writable position P2 in the concave portion 22 of the side surface 21 on the X2 side. It is a certain configuration.

  Therefore, the memory card connector to which the SD memory card is mounted has a configuration in which a switch for detecting the mounted SD memory card itself and a switch for detecting the position of the knob 23 are provided. .

  FIG. 1A shows a conventional memory card connector 1 with its cover removed. The memory card connector 1 is provided with a switch 10 for detecting the position of the knob 23 of the loaded SD card 20.

JP 2001-167844 A

  In general, in a switch including a movable terminal and a fixed terminal, a contact failure may occur due to foreign matter caught between the movable terminal and the fixed terminal. In the switch 10 described above, in order to avoid contact failure due to foreign matter being caught between the protrusion 12 b of the movable terminal 12 and the fixed terminal 11, the protrusion 12 b moves while rubbing the surface of the fixed terminal 11. It is important to make the wiping distance as long as possible.

  However, in the case of the switch 10 described above, the wiping direction is the direction Y1 orthogonal to the direction X2 in which the U-shaped portion 12a is pressed, and the wiping distance is extremely short. For this reason, it is difficult to increase the reliability of the switch 10, that is, the reliability of the memory card connector 1.

  Therefore, an object of the present invention is to provide a card connector that solves the above-described problems.

The present invention is a card connector comprising a detection switch having a movable terminal that is pushed and elastically bent by a mounted card and a fixed terminal that is spaced apart from the movable terminal.
The movable terminal has an arm portion that is elastically bent by being pushed by a card that is mounted, and a contact portion that extends in the same direction as the direction in which the arm portion bends from the arm portion. Yes,
The fixed terminal has a shape that is rubbed by the contact portion when the arm portion is bent,
When the arm portion is bent, the contact portion is displaced in the same direction as the bending direction of the arm portion so as to come into contact with and rub against the fixed terminal.

  Since the contact part is displaced in the same direction as the direction of bending of the arm part and contacts and rubs the fixed terminal, the distance that the contact part rubs the fixed terminal, that is, the wiping distance should be made much longer than before. As a result, the reliability of the detection switch is improved, and as a result, the reliability of the card connector is improved.

  Next, an embodiment of the present invention will be described.

  In each figure, X1-X2 is the width direction, Y1-Y2 is the longitudinal direction, and Z1-Z2 is the thickness (height) direction. Y1 is a direction in which the memory card is inserted into the memory card connector, and Y2 is a direction in which the memory card is ejected.

FIG. 8 shows the movable terminal member 141 of the first detection switch 140 and the movable terminal member 161 of the second detection switch 160 and the portion of the lower housing body 71 where they are press-fitted and fixed.

  The upper surface of the frame rod 73 of the lower housing body 71 has a shape in which the movable terminal member 141 and the movable terminal member 161 are press-fitted and fixed.

  The first detection switch 140 is for detecting that the SD memory card 20 or the multimedia card 40 is inserted, and is formed by cutting and raising the movable terminal member 141 and the side plate portion 123 of the cover member 120. The fixed terminal portion 125 is provided.

  The movable terminal member 141 in FIG. 7 is shown in the same direction as the direction fixed to the frame rod 73.

  The movable terminal member 141 is a part formed by press-molding a metal plate, and includes a base part 142, a bulge part 143 extending in a different direction from the base part 142, a lead terminal part 144, a long arm part 145, and an arm part 145. And a tip contact portion 146. The contact portion 146 has a horseshoe shape and is three-dimensional.

  The bulge portion 143 is bent in the Z2 direction from the base portion 142, and the lead terminal portion 144 is L-shaped and extends from the base portion 142 in the Y1 direction.

  The arm portion 145 extends in the Y2 direction from the portion 142a of the base portion 142 bent in the Z1 direction, is positioned in the YZ plane, and is flexibly elastically so that the tip is displaced in the X2 direction. sell. The arm portion 145 has a V-shaped tip portion 145a protruding in the X1 direction.

  The contact portion 146 includes two symmetrical lead portions 147 and 148. The lead portions 147 and 148 extend in a direction orthogonal to the arm portion 145, that is, in the Z1 and Z2 directions, have a crank shape, and are bent in the X2 direction, and are laterally viewed from the Y2 side. It has become. The lead portions 147 and 148 extend from the arm portion 145 in the X2 direction, that is, in the same direction as the direction in which the arm portion 145 is elastically bent. As shown in FIG. 6A, the lead portions 147 and 148 have leading end portions 147a and 148a protruding in opposite directions. The lead portions 147 and 148 are symmetrically inclined so that the distance between the tip portions 147a and 148a is narrowed. The angle α is about 10 degrees.

  The movable terminal member 141 has a bulge portion 143 that is press-fitted into the slit 73f of the frame rod 73 and a base portion 142 fixed thereto, and the contact portion 146 has a distal end facing the opening portion 73e, and an arm portion 145. It can be displaced in the X1-X2 direction by bending. That is, the contact portion 146 is displaced in the same direction as the direction in which the tip of the arm portion 145 is bent.

  As shown in FIGS. 6 (A) and 7 (A), the fixed terminal portion 125 is formed by cutting and raising the side plate portion 123 of the cover member 120 and has a substantially trapezoidal cross section. Further, lug portions 126 and 127 are bent in the X2 direction. The lug portion 126 on the Z1 side and the lug portion 127 on the Z2 side are inclined symmetrically so that the distance between the tip portions is widened when viewed from the root side. In other words, the lug portion 126 and the lug portion 127 are inclined outward with respect to the direction in which the contact portion 146 moves (direction X2). The angle β is about 25 degrees. That is, the fixed terminal portion 125 has a shape that is rubbed by the tip portions 147a and 148a when the contact portion 146 is displaced in the same direction as the tip of the arm portion 145 is bent. β and α have a relationship of β> α.

  As shown in FIG. 7A, the contact portion 146 is spaced apart from the fixed terminal portion 125. The first detection switch 140 is off.

  When the SD memory card 20 or the multimedia card 40 is inserted and attached, a portion close to the distal end in the insertion direction on the X2 side surface of the SD memory card 20 or the multimedia card 40 becomes the distal end 145a of the arm 145. Pushing away in the X2 direction, the arm portion 145 bends in the X2 direction, the contact portion 146 is displaced in the X2 direction, approaches the fixed terminal portion 125, and the tip portions 147a and 148a contact the lug portions 126 and 127, respectively. As shown in FIG. 7 (B), the lead parts 147 and 148 straddle the fixed terminal part 125 while moving so as to ride on the lug parts 126 and 127 while rubbing the surfaces of 126 and 127. Thus, the first detection switch 140 is turned on.

  Here, since the direction in which the contact portion 146 is displaced (X2 direction) is the same as the direction in which the arm portion 145 bends (X2 direction), the distance that the tip portions 147a and 148a move while rubbing the lug portions 126 and 127, respectively. L10 is several times longer than a conventional switch. As a result, the wiping action for removing foreign matter is stronger than in the prior art.

  Further, when the contact portion 146 comes into contact with the fixed terminal portion 125, the lead portions 147 and 148 are forcibly widened and elastically bent, and the lugs 126 of the tip portions 147a and 148a, The pressing force on 127 increases. This also strengthens the wiping action for removing foreign matter.

  Further, since the lead portions 147 and 148 of the contact portion 146 sandwich the fixed terminal portion 125, the contact portion 146 is slightly displaced in the Z direction with respect to the fixed terminal portion 125 in the state shown in FIG. Even when the contact portion 146 is in contact with the fixed terminal portion 125, the position of the contact portion 146 is corrected, and the contact of the tip portions 147a and 148a with the lug portions 126 and 127 is stabilized.

  Therefore, the first detection switch 140 has higher reliability than the conventional one, and the memory card connector 60 has higher reliability than the conventional one.

  The second detection switch 160 is for detecting that the knob 23 of the SD memory card 20 is set at the writable position P2, and is cut between the movable terminal member 161 and the side plate portion 123 of the cover member 120. It is composed of another fixed terminal portion 128 that is formed to be raised.

  The movable terminal member 161 is substantially the same as the movable terminal member 141, has a horseshoe-shaped contact portion 166 at the tip of the arm portion 165, and the fixed terminal portion 128 is the same as the fixed terminal portion 125. is there.

  Therefore, the second detection switch 160 operates in the same manner as the first detection switch 140, has higher reliability than the conventional one, and the memory card connector 60 has higher reliability than the conventional one.

  The first and second detection switches 140 and 160 can be configured such that one of the pair of lead portions is eliminated and one lead portion rubs the lug portion of the fixed terminal portion 125. .

  Further, the frame rod 73 is provided with a frame portion similar to the frame portion 180 shown in FIG. 9 described later, and the contact portion 146 is configured to be positioned by the frame portion in a state where the first detection switch 140 is off. It is also possible.

  Here, when the direction of wiping is a direction orthogonal to the direction in which the arm portion bends, in order to increase the wiping distance, the length of the arm portion needs to be considerably increased. The second detection switches cannot be arranged side by side. However, in the present embodiment, since the wiping direction is the same as the direction in which the arm bends, the lengths L1 and L2 of the movable terminal members 141 and 161 are sufficient, and the first and second detection switches 140 are sufficient. , 160 can be arranged side by side on the frame rod 73.

In the memory card connector 60, the leg portion of the cover member 120 is screwed to the printed circuit board of the electronic device and soldered to the ground pattern, and the lead terminal portion 144 and the movable terminal member 161 of the movable terminal member 141 are used. The lead terminal portion 164 of the first and second contact members 111 and 121 is soldered to the corresponding pad, and the printed circuit board is soldered to the end pad of the detection circuit pattern. Implemented and used above. Therefore, when the first and second detection switches 140 and 160 are turned on, the detection circuit operates as appropriate to control the electronic device.
