Description
- 1. Field of the Invention
- The present invention relates to card connectors for connecting a removable card to a circuit board and, more particularly, to a card connector for holding a removable card for a mobile device.
- 2. Description of the Related Art
- Such a card connector is disclosed in, for example, Japanese patent application Kokai Nos. 59-149576 (JP'576) and 11-135192 (JP'192).
- The connector of JP'576 comprises a sliding ejector member that abuts on an inserted card, a spring for biasing the ejector member in a card removing direction, a rotation support for locking the ejector member at a card insertion position, and an ejector lever for releasing the lock of the ejector member. To mount a card, the card is pushed into the insertion opening to lock the ejector member with the rotation support. To remove the card, the ejector lever is depressed to move the rotation support for release of the lock of the ejector member so that the spring pushes out the card.
- The connector of JP'192 comprises a body, a slider that is pushed into the body along with a card, a spring member provided between the body and the slider, and a cam mechanism consisting of a cam member and a pin member. The cam mechanism locks and unlocks the slider. Both of insertion and removal of a card is made by pushing the card or “push-push operation”.
- In the above connectors, however, the card insertion/removal mechanism, especially, the ejector member and/or the slider lock/unlock mechanism, is too complicated and too large in the number of components to provide a compact and inexpensive connector. In addition, the insertion/removal of a card is difficult because the card insertion/removal face of a mobile device is small.
- In the push-push type connector of JP'192, the end of a card projects from the mobile device so that not only the card can be damaged or fall when the mobile device is dropped but also the design choices are limited. Moreover, a space necessary for the push-push operation requires a wide body of the device. The length of sliding contact between the card contact point and the connector contact point becomes so large that the life of the contacts is shortened.
- Accordingly, it is an object of the invention to provide a card connector capable of reducing the number of components, simplifying the mechanism, reducing the manufacturing cost, and making the device compact.
- According to the invention there is provided a card connector for electrically connecting a removable card to a circuit board, comprising a case for supporting the removable card; a slider provided within the case for sliding along with the removable card in a card insertion/removal direction; a spring member for biasing the slider in a card removing direction; a lock member for locking the slider to the case when the removable card is inserted into the case; a release member operable from a major face of the case for releasing the slider from the case.
- It is preferred that the case comprises a case body of an insulative material; a plurality of terminals provided on the case body; a metal cover provided over the case body; and at least one fixing means for fixing the case to the circuit board. Also, the lock means may comprise a stopper arm cantilevered to a major face of the metal cover so as to be flexible for engagement with the slider. The release means comprises a release lever rotatable about a fulcrum to lift the stopper arm for releasing the slider from the case. Furthermore, the card connector may comprise a regulation means for regulating rotation of the release lever to thereby regulate movement of the stopper arm.
- According to another aspect of the invention there is provided a card connector for electrically connecting a removable card to a circuit board, comprising a case for accommodating the removable card; a slider provided within the case for sliding in a card insertion/removal direction; a spring member for biasing the slider in a card removing direction; a card retention arm cantilevered on the slider in the card insertion/removal direction and having an inward projection; a raised portion provided on the case so as to abut on an outer face of the card retention arm so that when a removable card with a notch provided on a side thereof is inserted into the case, the inward projection engages the notch and when the removable card is further inserted, the inward projection restricts outward movement of the card retention arm.
- It is preferred that the card retention arm comprises a downward projection and the raised portion has an inclined face with a rising gradient in a card insertion direction so that when a removable card with no notch provided on a side thereof is inserted into the case, the downward projection slides on the inclined face to lift the card retention arm while the card retention arm is flexed outwardly. Also, the card retention arm may have an engaging portion so that when a removable card with no notch on a side thereof is inserted into the case, the card retention arm is flexed outwardly and the engaging portion engages the raised portion. Furthermore, the slider comprises a card abutment for abutment with a front end of the removable card and a guide section for sliding on the case in the card insertion/removal direction. Moreover, the card abutment may comprise at least one support wall, the case has at least one raised portion for guiding the support wall so that if the removable card is inserted in a wrong direction, the raised portion blocks the slider, thereby preventing completion of such insertion.
- According to still another aspect of the invention there is provided a card connector for electrically connecting a removable card to a circuit board, comprising a case for accommodating the removable card; a slider provided within the case for sliding along with the removable card in a card insertion/removal direction; a spring member for biasing the slider in a removing direction; a card retention arm cantilevered to the slider in the card insertion/removal direction and having an inward projection and a downward projection at a front end thereof; an elongated groove provided in the case in the card insertion/removal direction so that when a removable card with a notch provided on a side thereof is inserted into the case, the inward projection engages the notch and the downward projection slides on the case and then engages the elongated groove to prevent the card retention arm from reflecting outwardly whereas when a removable card with no notch is inserted into the case, the card retention arm is flexed outwardly and the downward projection slides on the case outside the elongated groove.
- When the removable card is inserted into the case, the lock member engages the slider to lock the removable card in the case. The operation of the lock release member releases the slider from the lock member for removal of the removable card.

card 1 is a so-called memory card and is cut out at the front right-hand corner. It has a writeprotective switch 74 on the left-hand side and aretention notch 75 on the right-hand side. Also, it has a pair ofelongated shoulders 76 extending along the back-side side edges and a plurality ofterminal channels 77 in the front portion for supportingterminals 89. Alternatively, as shown in FIG. 21, anothercard 1′ that has neither write protective switch nor retention notch may be used. - The insertion/removal operation of the card connector will be described with reference to FIGS.2-16.
- In FIGS.2-4, when the
card 1 is not inserted into thecase 2, theslider 3 is pushed to the front position by thespring 32 and the engagingprojection 49 is fitted in the engaginghole 33 so that theslider 3 is kept without rattling. Thecard 1 is inserted into thecase 2, with theretention notch 75 being on the right-hand side. Since the front ends of theguide wall 15, thefront abutment 22, and thejaws card 1 to thecase 2. Thejaws arm sections card 1 from being inserted into thecase 2 upside down. - In FIGS. 5 and 6, when the
card 1 is inserted, thejaws arm sections shoulders 76 of thecard 1, and the right-hand side of thecard 1 makes contact with theinward projection 57 of thecard retaining arm 56 and flexes the retainingarm 56 to the right. Since theinward projection 57 is rounded, thecard retaining arm 56 is flexed smoothly. - In FIGS. 7 and 8, when the
card 1 is further inserted into thecase 2, the front end of thecard 1 abuts on thecard abutment 38 of theslider 3. At this point, theinward projection 57 fits into theretention notch 75, returning thecard retaining arm 56 to the original position. - In FIGS. 9 and 10, when the
card 1 is further inserted into thecase 2 to push forwardly theslider 3, the engagingprojection 49 disengages from the engaginghole 33 of thefront stopper 22 while thesupport walls terminal receiving section 6 between therespective terminals 11 to prevent thecard abutment 38 from bending downwardly. The raisedportion 14 guides thesupport wall 62 to prevent theslider 3 from tilting by the push of thecard 1. Thespring 32 is compressed by thespring abutment 47, and thedownward hook 68 of thestopper arm 67 slides on theinclined face 45 to the top of the raisedportion 44, flexing upwardly thestopper arm 67. Thecard terminals 89 slide on the contact points of theconnector terminals 11, flexing downwardly theconnector terminals 11. - In FIGS. 11 and 12, when the
card 1 is further inserted into thecase 2, thespring 32 is further compressed, and theshoulder 48 of theslider 3 abuts on therear slider stopper 21, restricting rear movement of theslider 3. At the same time, thestopper arm 67 flexes downwardly so that thedownward hook 68 engages the front face of the raisedportion 44, restricting forward movement of theslider 3. The outer face of thecard retention arm 56 makes contact with the inner face of the raisedportion 29 to prevent thecard retention arm 56 from moving to the right so that the engagement between theinward projection 57 and theretention notch 75 is locked to prevent falling of thecard 1. The card terminals are electrically connected to the contact points 12 of the connector to complete the insertion of thecard 1 into thecase 2. If the writeprotective switch 74 is at the rear position as shown in FIG. 19, the male andfemale terminals protective switch 74. - In FIGS.13-15, to remove the
card 1 from thecase 2, theoperation tab 72 is depressed so that thelock release lever 70 is rotated counterclockwise about thesupport stud 71. Consequently, the front end of thelock release lever 70 engages thedownward hook 68 of thestop arm 67 for lifting thestop arm 67. As a result, thedownward hook 68 is released from the raisedportion 44 so that theslider 3 is moved forwardly by thespring 32, bringing thecard 1 to the forward position. - In FIGS. 7 and 8, the
slider 3 abuts on thefront abutment 22 so that when thecard 1 is pulled rearwardly, thecard retaining arm 56 is flexed to the right, releasing theinward projection 57 from theretention notch 75 for completion of the removal of thecard 1. The inner side of theinward projection 57 is curved so that it is easy to remove thecard 1. - The insertion/removal of the
card 1′ from the card connector will be described with reference to FIGS. 16-18. The operation of thecard 11 is the same as that of thecard 1 except for the operation of thecard retaining arm 56 and, therefore, the description will center on the operation of thecard retaining arm 56. - When the
card 1′ is inserted into thecase 2, the right-hand side wall of thecard 11 abuts against theinward projection 57 of thecard retaining arm 56, flexing thecard retaining arm 56 to the right. - When the
card 1′ is further inserted into thecase 2, the front end of thecard 1′ abuts on thecard abutment 38 of theslider 3 to move theslider 3 rearwardly. Theslider 3 is prevented to move rearwardly by therear abutment 21 and forwardly by thestopper arm 67 so that thecard 1′ is locked in thecase 2. As best shown in FIG. 18, thedownward projection 58 of thecard retaining arm 56 slides on theinclined face 30 to the top of the raisedportion 29. Since there is thegap 59 under thecard retaining arm 56, such sliding movement is made smooth. The flexure of thecard retaining arm 56 to the right is not blocked by the raisedportion 29 so that thecard retaining arm 56 is not broken. Theinward projection 57 of thecard retaining arm 56 presses thecard 1′ to the left to prevent falling of thecard 1′. - To remove the
card 1′ from thecase 2, thelock release lever 70 is depressed so that thespring 32 moves theslider 3 and thecard 1′ forwardly up to thefront abutment 22. Thedownward projection 58 of thecard retaining arm 56 slides on theinclined face 30, and thecard 1′ is pulled rearwardly for removal. - Alternatively, the
card retaining arm 56 may be provided above or below the card. As shown in FIG. 22, thestopper arm 67 and thelock release lever 70 may be replaced by thestopper arm 79 having thedownward hook 78 and a curvedlock release lever 80 and asupport piece 81 provided below thelock release lever 80. When thelock release lever 80 is depressed with thesupport piece 81 as a fulcrum, thedownward hook 78 is lifted to release the lock. As shown in FIG. 23, thesupport piece 81 may be replaced by asupport wall 82 provided in front of the raisedportion 44 of theslider 3. - In FIG. 24, the
lock release lever 70 has a bifurcated rear end to hold the engagingpiece 69 therebetween and a over-rotationpreventive piece 84 at the front upper portion for engagement with the upper edge of the right-hand side wall 65. Arotation regulator 90 is moved into a space under theoperation tab 72 of thelock release lever 70 by means of a switch that is provided on the mobile device to regulate the movement of thelock release lever 70 after thestopper arm 67 engages theslider 3. The over-rotationpreventive piece 84 and therotation regulator 90 regulate the rotation of thelock release lever 70, and thelock release lever 70 regulates the movement of thestopper arm 67 so that unintentional release of thestopper arm 67 from theslider 3, which is caused by impact or vibration applied to thestopper arm 67 when the mobile device is dropped, is prevented. Also, it is prevented that thelock release lever 70 rotates so much that thefront end 83 is lifted too much to engage thestopper arm 67. - An operation tab may be provided on the upper or lower face of the mobile device to indirectly operate the
operation tab 72, thereby not only facilitating the operation but also providing more design choices. In order to improve the resiliency and durability of the card retaining arm, the card retaining arm may be made separately from theslider 3 and of a metal or other resilient material than synthetic materials. For example, a card retaining arm of a metal piece is provided obliquely along the moving direction of theslider 3. In FIGS. 25-27, acard retaining arm 85 has aninward projection 86 and afront jaw 87, and a raisedportion 88 has a flat form having a curved front face. When thecard 1 with theretention notch 75 is inserted into thecase 2, theinward projection 86 fits in theretention notch 75. When thecard 1 is further inserted, the raisedportion 88 blocks thecard retaining arm 85 from moving outwardly, preventing falling of thecard 1. As shown in FIGS. 26 and 27, when thecard 1′ with no retention notch is inserted into thecase 2, thecard retaining arm 85 is flexed outwardly and thefront jaw 87 engages the outer side of the raisedportion 88. Alternatively, the raisedportion 88 may be provided on thecase cover 5 and thefront jaw 87 may be bent upwardly. - In order to restrict the outward movement of the card retaining arm, the raised
portion 88 may be replaced by an elongated groove provided in the step-downportion 25. The card retaining arm has an inward projection and an downward abutment such that the lower end of the downward abutment abuts on the step-downportion 25 and is flexed upwardly so that it is able to slide on the step-downportion 25 as theslider 3 moves. When thecard 1 is inserted to a predetermined position, thedownward abutment 87 fits in the elongated groove to restrict outward movement of thecard retaining arm 85. When thecard 1′ is inserted, thedownward abutment 87 is flexed outwardly and slides on the step-downportion 25 and does not fit in the elongated groove. The card connector according to the invention is also useful for other cards such as an IC card that is mounted on a mobile device. - As has been described above, according to the invention, it is possible to reduce the number of components and simplify the mechanism to reduce the manufacturing cost and make the device compact. In addition, it is possible to make the lock release operation on the major face of the device, thus improving the operation. The same connector may be used for both types of cards with or without a retaining notch, reducing the manufacturing cost and preventing confusion in use.
