Description

  The present invention relates to a card connector used in an electronic device such as a cellular phone, and to which a card such as an IC memory card is mounted, and more particularly, a housing in which a contact group that can contact a contact terminal group of the card is disposed. The present invention relates to a card connector in which a cover is attached so as to be openable and closable (rotatable), and the card can be prevented from falling off by this cover.

  Conventionally, in this type of card connector, it is detected whether or not the card is correctly inserted without fear of dropping, so that an undesired data signal is not exchanged between the card and an external circuit. Thus, there has been proposed a method in which data destruction or failure due to an erroneous operation does not occur (see, for example, Patent Document 1).

In such a conventional card connector, a card storage portion is formed in a cover made of an insulating synthetic resin material, and the card can be inserted into and removed from the card storage portion when the cover is open. The cover is provided with a spring piece that elastically deforms when the card is correctly stored in the card storage portion. One end of the cover is pivotally supported by the housing and can be opened and closed. The closed cover is slidable with respect to the housing, and the cover is locked to the housing by sliding the closed cover to a predetermined position. It has come to be. A plurality of contacts are fixed to the housing, and each contact portion of these contacts is exposed at a position covered by a closed cover. Moreover, the 1st contact piece and 2nd contact piece which can be elastically deformed are arranged in parallel by the one side part of the housing so that contact / separation is possible. Then, after inserting the card into the cover, when the cover is closed and the cover is closed and slid in one direction, the contact terminal group arranged on one side of the card comes into contact with each contact portion of the contact group. The first contact piece driven by the spring piece of the cover contacts the second contact piece while being electrically connected, and a detection signal is output indicating that the card is correctly installed without fear of dropping off. It has become so. That is, in such a conventional card connector, the first contact piece is brought into contact with the second contact piece via the spring piece when the card is correctly stored in the cover and the cover is closed and is not slid to a predetermined position. Since a series of operations are not performed correctly, the detection signal is not output. Therefore, if the data signal is allowed to be exchanged between the card and the external circuit only when this detection signal is output, data destruction or failure due to an erroneous operation can be prevented beforehand.
Japanese Patent No. 3546387

  By the way, in the conventional card connector described above, by storing the card in the cover and then closing and sliding the cover, the card is correctly mounted and can be electrically connected to an external circuit via the connector. However, in recent years, electronic devices such as mobile phones that are configured to prevent a dropout by closing a cover after a card is mounted in a housing have become widespread. In the case of the card connector having such a structure, although there is an advantage that an inexpensive and thin cover made of a metal plate or the like can be used, it covers the spring piece that is elastically deformed by storing the card like the conventional card connector described above. In order to avoid data destruction or failure due to erroneous operation, a new mechanism for detecting whether or not the card is correctly inserted is required.

  The present invention has been made in view of the situation of the prior art as described above, and its purpose is to close the cover after the card is mounted on the housing, and whether or not the card is correctly mounted. An object of the present invention is to provide an inexpensive card connector that can be detected and is suitable for miniaturization and thinning.

  In order to achieve the above object, the present invention provides a housing in which a card mounting portion for mounting a card having a contact terminal group is formed, and a contact group provided in the housing and capable of contacting the contact terminal group. And a cover rotatably attached to the housing so that a closing operation that rotates in a direction to cover the card mounting portion and an opening operation that rotates in a direction away from the card mounting portion can be performed. In the card connector in which the contact group is brought into contact with the contact terminal group by being mounted on the card mounting portion, and the card is stored and held in a state where the cover is disposed at a predetermined closed position, When the contact group includes a first contact and a second contact that can contact a predetermined contact terminal that is one of the contact terminal groups. In addition, at least a part of the cover is made of a conductive metal plate, and is connected to an external circuit derived from the first contact and the cover is disposed at the predetermined closed position. A fixed contact portion that is brought into contact with the cover when connected, and a second external connection portion that is led out from the fixed contact portion and connected to an external circuit. The external connection portion and the fixed contact portion are provided in the housing.

  In the card connector configured as described above, the contact group can be brought into contact with the contact terminal group by mounting the card on the card mounting portion of the housing. At this time, the first and second contacts are brought into contact with the predetermined contact terminal. Therefore, it is possible to detect whether or not the card is correctly mounted on the card mounting portion based on a signal resulting from the conduction of the first and second contacts. Further, when the cover is closed so as to cover the card mounted on the card mounting portion and placed at a predetermined closed position, a signal is generated when the card contacts the fixed contact portion and is electrically connected to the second external connection portion. Based on this, it is possible to detect whether or not the cover is disposed at a predetermined closed position. That is, the card connector detects a desired detection from the first external connection portion or the second external connection portion only when the card is correctly attached to the card attachment portion and the cover is disposed at a predetermined closed position. Since the signal can be output, it is possible to prevent data destruction or failure due to erroneous operation. In addition, since it is not necessary to provide a card storage portion in the cover, an inexpensive and thin cover made of a metal plate or the like can be used, and it is easy to achieve a reduction in size and thickness.

  The card connector configured as described above includes a first ground terminal portion that is led out from the second contact and connected to the ground circuit. When the first ground terminal portion is provided in the housing, the card It is preferable because it is possible to detect whether or not the card is correctly inserted while grounding.

  Further, in the above configuration, the fixed contact portion includes a first fixed contact portion and a second fixed contact portion that are separately in contact with two places of the cover disposed at a predetermined closed position. A second external connection portion is led out, and a second ground terminal portion led out from the second fixed contact portion and connected to the ground circuit is provided, and the second ground terminal portion is provided in the housing. In addition to being able to ground the cover, a total of four mounting terminal parts (first and second external connection parts and first and second grounding terminal parts) are distributed in the housing. Therefore, the card connector can be mounted on the mounting substrate in a stable posture.

  For example, a first external connection portion and a second external connection portion are disposed near both longitudinal ends of one side of the housing, and the first ground terminal portion is disposed near both longitudinal ends of the other side of the housing. Since the four mounting terminal portions are distributed and arranged in a balanced manner, the card connector can be mounted on the mounting substrate in a very stable posture.

  In the above configuration, the cover is formed by bending one conductive metal plate, and an elastic piece that can contact and separate from the fixed contact portion extends on the side of the cover. A simple structure capable of reliably bringing the elastic piece into contact with the fixed contact portion when arranged at a predetermined closed position is preferable because it can be realized at low cost.

  Further, in the above configuration, the cover is slidable with respect to the housing between the completion position of the closing operation and the predetermined closed position, and a lock mechanism for locking the cover in the predetermined closed position by the housing. If provided, this lock mechanism can prevent the card attached to the housing from falling off reliably, which is preferable.

  According to the card connector of the present invention, when the card is correctly mounted on the card mounting portion of the housing, the first and second contacts come into contact with the predetermined contact terminal. It is possible to detect whether or not the card is correctly mounted on the card mounting portion. Further, when the cover is closed so as to cover the card mounted on the card mounting portion and placed at a predetermined closed position, a signal is generated when the card contacts the fixed contact portion and is electrically connected to the second external connection portion. Based on this, it is possible to detect whether or not the cover is disposed at a predetermined closed position. That is, the card connector detects a desired detection from the first external connection portion or the second external connection portion only when the card is correctly attached to the card attachment portion and the cover is disposed at a predetermined closed position. Since the signal can be output, it is possible to prevent data destruction or failure due to erroneous operation. In addition, since it is not necessary to provide a card storage portion in the cover, an inexpensive and thin cover made of a metal plate or the like can be used, and it is easy to achieve a reduction in size and thickness.

It is slidably mounted in the direction.

  The contact 3 is formed in a band shape and has a contact portion 3a at one end portion, and the one end portion side extends obliquely upward to be elastically deformable. As shown in FIG. 1, when the card 10 is not mounted, the contact portion 3 a of each contact 3 enters the card mounting portion 2 a of the housing 2. The plurality of contacts 3 are arranged so that each contact portion 3a elastically contacts the corresponding contact terminal 11 of the card 10 when the card 10 is correctly attached to the card attachment portion 2a. However, the first contact 31 and the second contact 32 adjacent to each other in the group of contacts 3 are close to each other so that the contact portions 3a are close to each other so that they are in elastic contact with the same contact terminal 11 (ground contact terminal 11a in the figure). is there. The remaining contacts 3 except for the first and second contacts 31 and 32 are soldered by mounting an end portion 3b opposite to the contact portion 3a side on a mounting board of an electronic device. Yes.

  One end of the lead plate 4 is continuous with the first contact 31, and a first external connection 41 connected to an external circuit is formed at the other end. The first external connection portion 41 protrudes outward from the vicinity of the front end of the side wall portion 21 of the housing 2 and serves as an attachment terminal portion that is mounted on a mounting board of an electronic device and soldered. Similarly, one end portion of the lead plate 5 is continuous with the second contact 32, and the first ground terminal portion 51 connected to the ground circuit is formed at the other end portion. The first ground terminal portion 51 protrudes outward from the vicinity of the front end of the side wall portion 22 of the housing 2 and serves as an attachment terminal portion that is mounted on a mounting board of an electronic device and is firmly soldered.

  A first fixed contact portion 61 is formed at one end of the lead plate 6, and a second external connection portion 62 connected to an external circuit is formed at the other end of the lead plate 6. The lead plate 6 is fixed to the side wall portion 21 of the housing 2.

Become.

  The cover 8 is formed by punching or bending a single conductive metal plate, and the support shaft 81 is rotatably attached to the housing 2, so that the cover 8 has a card mounting portion 2a. A closing operation that rotates in a direction to cover the card and an opening operation that rotates in a direction away from the card mounting portion 2a can be performed. Further, the cover 8 is slidable with respect to the housing 2 between the closing operation completion position shown in FIG. 6 and a predetermined closing position (locking position) shown in FIG. 8, one side is disposed outside the side wall 21 and the other side is disposed outside the side wall 22. An elastic piece 82 that can be brought into and out of contact with the first fixed contact portion 61 extends on one side portion of the cover 8, and a hook piece 83 that can be attached to and detached from the first locking portion 21 a and a second engagement portion. A hook piece 84 that can be engaged with and disengaged from the stopper 21b is formed in a substantially L shape.

The hook piece 87 which can be engaged / disengaged with the 2 latching | locking part 22b is formed in the substantially L shape. As will be described later, in the state shown in FIG. 6 in which the cover 8 has completed the closing operation, the elastic pieces 82 and 85 are not in contact with the fixed contact portions 61 and 71, and the hook pieces 83 and 86 are in the first engagement. The hook pieces 84 and 87 are not locked to the second locking portions 21b and 22b, and are not locked to the locking portions 21a and 22a. Then, by sliding the cover 8 to the predetermined closed position shown in FIG. 7, the elastic pieces 82 and 85 are in contact with the fixed contact portions 61 and 71, and the first locking portions 21a and 22a are hook pieces 83. 86, and the second locking portions 21b, 22b lock the hook pieces 84, 87. That is, the cover 8 shown in FIG. 7 is arranged at the lock position so that it cannot move freely with respect to the housing 2. The first locking portions 21a and 22a and the second locking portions 21b and 22b of the housing 2 and the hook pieces 83, 84, 86, and 87 of the cover 8 lock the cover 8 in the locked position to the housing 2. A lock mechanism is configured.

  Next, a procedure for attaching the card 10 to the connector 1 configured as described above will be described. First, as shown in FIGS. 1 to 5, after opening the cover 8 to expose the card mounting portion 2a of the housing 2, the card 10 is mounted on the card mounting portion 2a as shown in FIGS. . At this time, the notch 10a at one corner of the card 10 is positioned by the wide portion 22d of the housing 2, and the recess 10b in the vicinity of the notch 10a of the card 10 is positioned by the protrusion 22e of the housing 2, so that the card It is easy to correctly attach the card 10 to the mounting portion 2a. When the card 10 is correctly installed, the contact terminals 11 come into contact with the contact portions 3a of the corresponding contacts 3, so that the contact terminals 11 and the contacts 3 are electrically connected. As a result, a signal (referred to as a “first detection signal”) resulting from the conduction of the first contact 31 and the second contact 32 through the predetermined contact terminal 11 (ground contact terminal 11a) is the first. Based on the presence / absence of the first detection signal, it is possible to detect whether or not the card 10 is correctly attached to the card attachment portion 2a. However, since the cover 8 is still open in this state and the elastic pieces 82 and 85 are not in contact with the fixed contact portions 61 and 71, the fixed contact portions 61 and 71 are kept in a non-conductive state. Therefore, a signal (referred to as “second detection signal”) that is generated when both the fixed contact portions 61 and 71 are conducted through the cover 8 is not output from the second external connection portion 62. In this embodiment, when both the first detection signal and the second detection signal are output, the card 10 and the external circuit are connected via the contact 3 group excluding the first and second contacts 31 and 32. Since the transmission / reception of the data signal is set to be permitted, the transmission / reception of the data signal is not yet executed at this time.

  When the card 10 is mounted on the card mounting portion 2a of the housing 2, the card mounting portion 2a is covered with the cover 8 by rotating the cover 8 around the support shaft 81 in the closing direction. The cover 8 is locked to the housing 2 as shown in FIGS. That is, by the sliding movement, the elastic pieces 82 and 85 of the cover 8 get over the inclined protrusions 21c and 22c of the housing 2 and elastically contact the fixed contact portions 61 and 71, respectively. 22a locks the hook pieces 83 and 86, and the second locking portions 21b and 22b lock the hook pieces 84 and 87, respectively, so that the cover 8 is in a predetermined closed position shown in FIGS. In the locked position), it is locked in the housing 2. Therefore, in this state, the card 10 attached to the housing 2 is reliably prevented from falling off by the cover 8. Further, since the cover 8 in the locked state is in contact with the upper surface of the card 10 to slightly push and bend the contact 3 group, the contact 3 group is elastically contacted with the contact terminal 11 group so that sufficient contact pressure can be obtained. ing. Further, when the cover 8 is disposed at the locked position, the elastic piece 82 elastically contacts the first fixed contact portion 61 and the elastic piece 85 elastically contacts the second fixed contact portion 71, so that both the fixed contact portions 61 and 71 are covered. Whether or not the cover 8 is disposed at a predetermined closed position based on the presence or absence of the second detection signal is output from the second external connection unit 62 due to the electrical connection via 8. Can be detected. As described above, when both the first detection signal and the second detection signal are output, it can be confirmed that the card 10 is correctly installed without fear of dropping off. The exchange of data signals between them is permitted.

  As described above, the connector 1 according to this embodiment can contact the contacts 3 corresponding to the contact terminals 11 group by opening the cover 8 and mounting the card 10 to the card mounting portion 2a of the housing 2, respectively. At this time, since the first and second contacts 31 and 32 are in contact with the predetermined contact terminal 11 (the ground contact terminal 11a), the first and second contacts 31 and 32 are output when the first and second contacts 31 and 32 are conducted. Based on the 1 detection signal, it can be detected that the card 10 is correctly mounted in the card mounting portion 2a. That is, when the card 10 is not attached or not properly attached to the card attachment portion 2a, the first detection signal is not output because the first and second contacts 31, 32 are not short-circuited. When the cover 8 is closed so as to cover the card 10 mounted on the card mounting portion 2a and the cover 8 is slid to a predetermined closed position (lock position), the elastic pieces 82 and 85 of the cover 8 are fixed contacts. The cover 8 is locked to the housing 2 at the lock position based on the second detection signal that is output when both the fixed contact portions 61 and 71 are conducted through the cover 8 to contact the portions 61 and 71. Can be detected. That is, when the cover 8 is not closed or is not closed and is not disposed at the locked position, the first and second fixed contact portions 61 and 71 are not short-circuited, so that the second detection signal is not output. Only when both the first detection signal and the second detection signal are output and it is confirmed that the card 10 is correctly attached without fear of dropping off, the data signal is exchanged between the card 10 and the external circuit. Since the connector 1 is permitted, the connector 1 can prevent data destruction or failure caused by an erroneous operation.

  Further, in the connector 1, a first ground terminal portion 51 is led out from a second contact 32 that comes into contact with the ground contact terminal 11a of the card 10 mounted on the card mounting portion 2a. Since the unit 51 is connected to the ground circuit, it is possible to detect whether or not the card 10 is correctly mounted while grounding the card 10. In addition, the connector 1 has a second ground terminal portion 72 led out from the second fixed contact portion 71 that comes into contact with the cover 8 disposed at the lock position. The second ground terminal portion 72 is connected to the ground circuit. Therefore, it is possible to detect whether or not the cover 8 is disposed at the lock position while grounding the cover 8. That is, the connector 1 can ground the card 10 and the cover 8 using a mechanism for detecting whether or not the card 10 is correctly installed without fear of dropping off, so that the card mounting state is not complicated. Detection and grounding countermeasures can be performed.

  In the connector 1, the cover 8 is formed by bending one conductive metal plate and has elastic pieces 82 and 85 on both sides, and the cover 8 is in a predetermined closed position (lock position). When the sliding movement is made, the elastic pieces 82 and 85 are configured to elastically contact the fixed contact portions 61 and 71 over the inclined protrusions 21c and 22c, respectively. The elastic pieces 82 and 85 can be reliably brought into contact with the fixed contact portions 61 and 71, and there is no possibility that the cover 8 is inadvertently slid in the reverse direction. Moreover, since the card storage portion is unnecessary and an inexpensive and thin cover 8 can be used, the connector 1 can be easily reduced in size and thickness, and the manufacturing cost can be easily suppressed.

  Further, the connector 1 is provided with a first external connection portion 41 and a second external connection portion 62 in the vicinity of both longitudinal ends of one side of the housing 2, and both longitudinal ends of the other side of the housing 2. A first ground terminal portion 51 and a second ground terminal portion 72 are disposed in the vicinity. Therefore, the housing 2 is mounted on the mounting board by the four mounting terminal portions (the first and second external connection portions 41 and 62 and the first and second ground terminal portions 51 and 72) that are distributed in a balanced manner. It can be mounted in an extremely stable posture.

  In the above-described embodiment, the case where the lead plate 5 and the lead plate 7 are discontinuous has been described. However, the lead plates 5 and 7 may be continuous. The first ground terminal portion 51, the second fixed contact portion 71, and the second ground terminal portion 72 are always conducted and connected to the ground circuit. In this case, when the card 10 is mounted on the card mounting portion 2a and the cover 8 is disposed at a predetermined closed position, the first external connection portion 41 and the second external connection portion 62 are short-circuited. Thus, by detecting this short circuit, the correct mounting of the card 10 to the card mounting portion 2a and the placement of the cover 8 at a predetermined closed position can be detected simultaneously.

  In the above-described embodiment, the first fixed contact portion 61 and the second fixed contact portion 71 that can be brought into and out of contact with the cover 8 are provided, and the second external connection portion 62 is led out from the first fixed contact portion 61. The case where the second grounding terminal portion 72 is led out from the second fixed contact portion 71 has been described. However, if the cover 8 has a grounding terminal portion that is always conducted, the cover 8 is provided with the first fixed contact portion. It is also possible to adopt a configuration in which only 61 is contacted and separated.

  In the above embodiment, the case where the cover 8 is slidable with respect to the housing 2 between the closing position of the closing operation and the locking position has been described. However, when the closing operation is completed, the cover 8 is moved to the housing. It can also be configured to be locked to 2.
