Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector in which deformation of a conductive terminal can be evaded while preventing invasion of dust and dirt into a housing space, and an electronic equipment. <P>SOLUTION: In the connector 25, a moving member 37 can move, for example, from a retreating position toward an advancing position in the housing space of a body 26. The moving member 37 moves along the conductive terminal 29, thereby, deformation and breakage of the conductive terminal 29 can be surely evaded. At this time, dust and dirt in the housing space of the body 26 is swept away by the moving member 37. Thereby, remaining of the dust and dirt in the housing space can be evaded. Such movement of the moving member 37 is realized by operation of an operating member 35. Sweeping of the dust and dirt can be implemented arbitrarily by a user of the connector 25. Further, if the moving member 37 is, for example, arranged always at the advancing position, invasion of the dust and dirt into the housing space is prevented by action of the moving member 37. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a connector such as a USB (Universal Serial Bus) connector.

For example, as disclosed in Patent Document 2, the connector receiving port is closed with a protective pad. For example, dust can be prevented from entering the connector by the function of the protective pad. A conductive terminal contacts the side surface of the protective pad. When, for example, a printed circuit board is inserted from the receiving port, the protective pad is pushed into the connector. The conductive terminal of the connector is pressed against the conductive terminal on the printed circuit board based on the elastic force. Thus, the conductive terminals on the printed circuit board are electrically connected to the conductive terminals of the connector.
JP 2001-230017 A Japanese Utility Model Publication No. 5-23464

  The conductive terminal of the connector always presses the tip against the side of the protective pad based on the elastic force. The conductive terminal of the connector is always forced to elastically deform. In order to avoid the entrance of dust, the protective pad that closes the receiving opening matches the outline of the receiving opening. On the other hand, the outline of the printed circuit board is smaller than the outline of the receiving port. Therefore, when the printed circuit board is not inserted, the elastic force of the conductive terminal of the connector is weakened over time. The stability of the connection between the conductive terminal of the connector and the conductive terminal of the printed circuit board cannot be maintained.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector and an electronic apparatus that can prevent deformation of a conductive terminal while preventing dust from entering the housing space.

  In order to achieve the above object, according to the first aspect of the present invention, the main body defining a housing space extending rearward from the front-end receiving port, the conductive terminal disposed in the housing space of the main body, and the housing space of the main body are disposed. A moving piece connected to the main body movably along the conductive terminal between a retracted position retracted from the receiving port and an advanced position arranged at the receiving port, and connected to the moving piece at one end and at the other end There is provided a connector including an operation piece disposed outside the main body and realizing movement of the moving piece.

  In such a connector, the moving piece can move, for example, from the retracted position toward the advanced position within the housing space of the main body. Since the moving piece moves along the conductive terminal, deformation or breakage of the conductive terminal is reliably avoided. At this time, dust in the housing space of the main body is swept away by the moving piece. Dust remains in the storage space. Such movement of the moving piece is realized based on the operation of the operating piece. Dust sweeping can be performed arbitrarily by the user of the connector. In addition, for example, if the moving piece is always arranged at the forward movement position, the moving piece prevents dust from entering the accommodation space.

  According to the second aspect of the present invention, the main body that defines the housing space extending rearward from the receiving port at the front end, the conductive terminal that is disposed in the housing space of the main body, and the retracted position that is disposed in the housing space of the main body and is retracted from the receiving port. , And a moving piece connected to the main body movably along the conductive terminal between the advance positions arranged in the receiving port, a first magnet incorporated in the moving piece, and a first magnet arranged in the main body And a second magnet that generates a repulsive force that pushes the moving piece from the retracted position toward the advanced position.

  In such a connector, the moving piece is realized based on mutual repulsion of the first magnet and the second magnet. As a result, the structure in the housing space of the main body is simplified. In addition, as described above, the moving piece moves along the conductive terminal, so that the deformation or breakage of the conductive terminal is reliably avoided. In addition, dust in the housing space of the main body is swept away by the moving piece. Dust remains in the storage space. In addition, since the moving piece is always disposed at the forward movement position based on the repulsive force of the second magnet, the moving piece prevents dust from entering the accommodation space.

Is provided.

  In such an electronic device, the moving piece is realized based on mutual repulsion between the first magnet and the second magnet. As a result, the structure in the housing space of the connector body is simplified. In addition, as described above, the moving piece moves along the conductive terminal, so that the deformation or breakage of the conductive terminal is reliably avoided. In addition, dust in the housing space of the connector body is swept away by the moving piece. Dust remains in the storage space. In addition, since the moving piece is always disposed at the forward movement position based on the repulsive force of the second magnet, the moving piece prevents dust from entering the accommodation space.

  In such an electronic device, the movement of the moving piece is realized based on the sliding movement of the operation lever. The dust can be swept out arbitrarily by the user of the electronic device. In addition, as described above, the moving piece moves along the conductive terminal, so that the deformation or breakage of the conductive terminal is reliably avoided. Dust remains in the storage space.

  As described above, according to the present invention, it is possible to provide a connector and an electronic device that can prevent deformation of the conductive terminal while preventing dust from entering the housing space.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 schematically shows an appearance of a specific example of an electronic apparatus according to the present invention, that is, a notebook personal computer (notebook personal computer) 11. The notebook personal computer 11 includes a thin main body housing 12 and a display housing 13 that is swingably connected to the main body housing 12. Input devices such as a keyboard 14 and a pointing device 15 are incorporated on the surface of the main housing 12. The user can input instructions and data from these input devices 14 and 15.

  For example, an LCD (liquid crystal display) panel module 16 is incorporated in the display housing 13. The screen of the LCD panel module 16 faces the window hole 17 defined in the display housing 13. Text and graphics are displayed on the screen. The user can confirm the operation of the notebook computer 11 based on such text and graphics. The display housing 13 is overlaid on the main body housing 12 through swinging with respect to the main body housing 12.

  An opening, that is, a USB port 21 is formed in the side wall of the main body housing 12. A later-described female connector, that is, a USB connector 22 is incorporated in the USB port 21. For example, a USB memory 23 is attached to the USB port 21. A male connector, that is, a USB connector 25 is connected to the front end of the housing 24 of the USB memory 23. As is well known, a flash memory chip is accommodated in the housing 24. The casing 24 is made of, for example, a resin material. Data is stored in the flash memory chip. Such a USB memory 23 is used as an external storage device of the notebook computer 11.

  As shown in FIG. 2, the USB connector 25 includes a main body 26 made of metal, for example, attached to the front end of the housing 24. The main body 26 is formed in a rectangular parallelepiped shape, for example. A receiving port 27 is defined at the front end of the main body 26. The main body 26 defines, for example, a rectangular parallelepiped housing space extending rearward from the receiving port 27. For example, a resin support plate 28 is disposed in the housing space. For example, four conductive terminals 29 extending in parallel with each other are formed on the support plate 28. The conductive terminal 29 extends in the front-rear direction of the USB memory 23. A pair of openings 31 arranged in the width direction of the USB memory 23 is formed in the top plate and the bottom plate of the main body 26.

  A notch 32 is formed in the top plate of the main body 26 adjacent to the rear end of the main body 26. The notch 32 connects the housing space of the main body 26 and the external space. The notch 32 extends in the front-rear direction of the USB memory 23. A groove 33 formed in the housing 24 is connected to the rear end of the notch 32. The groove 33 extends in the front-rear direction of the USB memory 23. A guide groove 34 is formed by the notches 32 and the grooves 33. For example, a resin operation piece 35 is disposed in the guide groove 34. The operation piece 35 can move in the front-rear direction of the USB memory 23 based on the guidance of the guide groove 34. A knob 36 protruding from the surface of the housing 24 is defined at one end of the operation piece 35.

  As shown in FIG. 3, the operation piece 35 is formed in an L shape, for example. The other end of the operation piece 35 is connected to a movable piece 37 made of resin, for example, which is accommodated in the accommodation space of the main body 26. The moving piece 37 is formed in a rectangular parallelepiped shape, for example. Here, the operation piece 35 and the moving piece 37 may be formed from a resin material based on integral molding, for example. Referring also to FIG. 4, the moving piece 37 is disposed in the accommodation space outside the conductive terminal 29. When the knob 36 of the operation piece 35 is arranged at the rear end position of the guide groove 34, the moving piece 37 is arranged at the retreat position where the operation piece 35 is retreated from the receiving port 27. In the retracted position, the moving piece 37 is arranged behind the rear end of the conductive terminal 29.

  When the operation piece 35 moves toward the front end of the guide groove 34, the moving piece 37 slides in the accommodation space of the main body 26 along the surface of the conductive terminal 29. Since the moving piece 37 is disposed outside the conductive terminal 29, the moving piece 37 moves along the conductive terminal 29 outside the conductive terminal 29. As a result, for example, dust adhering to the conductive terminal 29 or the inner wall surface of the main body 26 is scraped off by the moving piece 37. Thus, as shown in FIG. 5, the knob 36 of the operation piece 35 is positioned at the front end position of the guide groove 34. As shown in FIG. 6, the moving piece 37 is positioned at an advanced position arranged in the receiving port 27. The dust scraped off is swept out from the receiving port 27 to the outside. Remaining dust in the USB connector 25 is avoided. Such dust sweeping can be performed arbitrarily by the user of the USB memory 23.

  As shown in FIG. 7, the USB connector 22 is incorporated in the USB port 21. The USB connector 22 is mounted on the printed circuit board 41, for example. The USB connector 22 includes a main body 42 made of, for example, metal. The main body 42 has, for example, a rectangular parallelepiped outline. A receiving port 43 is defined at the front end of the main body 42. The receiving port 43 faces the USB port 21 of the main body housing 12. The main body 42 defines, for example, a rectangular parallelepiped accommodation space extending rearward from the receiving port 43. For example, a resin support plate 44 is disposed in the accommodation space. Referring also to FIG. 8, for example, four conductive terminals 45 extending in parallel with each other are formed on the support plate 44. The conductive terminal 45 is formed from a leaf spring, for example.

  A pair of leaf springs 46 is disposed between the surface of the support plate 44 and the inner wall surface of the top plate of the main body 42. The leaf spring 46 exerts an elastic force toward the support plate 44 based on the bending. The leaf spring 46 is received in an opening 47 formed in the top plate of the main body 42. Thus, the displacement of the leaf spring 46 is allowed. Similarly, a pair of leaf springs 48 are disposed between the back surface of the support plate 44 and the inner wall surface of the bottom plate of the main body 42. The leaf spring 48 exerts an elastic force toward the support plate 44 based on the bending. The leaf spring 48 is received in an opening 49 formed in the bottom plate of the main body 42. Thus, the displacement of the leaf spring 48 is allowed.

  A predetermined gap is defined between the leaf spring 48 and the support plate 44. A moving piece 51 is disposed in the gap. The moving piece 51 is positioned at an advanced position arranged at the receiving port 43. The moving piece 51 is formed in a rectangular parallelepiped shape, for example. Both ends of the moving piece 51 are received in guide grooves 52 formed in the side plate of the main body 42. The guide groove 52 extends in the front-rear direction of the USB connector 22. Guide pieces 53 and 53 are integrated with both ends of the moving piece 51 outside the main body 42. The guide piece 53 restricts the moving piece 51 from dropping from the guide groove 52. Thus, the moving piece 51 can slide in the front-rear direction of the USB connector 22 between the advanced position and the retracted position retracted from the receiving port 43, as shown in FIG. . Since the moving piece 51 is disposed in the gap, the moving piece 51 moves along the conductive terminal 45 outside the conductive terminal 45.

  A first magnet 54 is incorporated in the moving piece 51. On the other hand, a second magnet 55 is incorporated at the rear end of the main body 42. The first magnet 54 and the second magnet 55 are formed of, for example, permanent magnets. Between the first magnet 54 and the second magnet 55, the same polarity magnetic poles face each other. The first magnet 54 and the second magnet 55 repel each other. As a result, the second magnet 55 can generate a repulsive force that pushes the moving piece 51 from the retracted position toward the advanced position. Based on such a repulsive force, the moving piece 51 is positioned at the forward movement position. At this time, the moving piece 51 is received at the front end of the guide groove 52. Thus, the moving piece 51 partially closes the receiving port 43 at the advanced position. As a result, entry of dust into the accommodation space of the main body 42 is avoided as much as possible.

  Now, assume that the USB memory 23 is inserted into the USB port 21. As shown in FIG. 10, the front end of the support plate 28 of the USB connector 25 is abutted against the front end of the moving piece 51 of the USB connector 22. The main body 26 of the USB connector 25 is received in the main body 42 of the USB connector 22. The support plate 28 pushes the moving piece 51 toward the retracted position against the repulsive force of the second magnet 55. The support plate 28 enters a gap defined between the support plate 44 and the leaf spring 48. At the same time, the support plate 44 enters between the support plate 28 and the top plate of the main body 26.

  As shown in FIG. 11, when the USB connector 25 is completely inserted into the USB connector 22, the front end of the support plate 28 pushes the moving piece 51 to the retracted position. The conductive terminal 29 on the support plate 28 contacts the conductive terminal 45 on the support plate 44. The conductive terminal 45 presses the tip on the conductive terminal 29 based on elastic force. At this time, the leaf spring 46 is received in the opening 31 of the top plate of the main body 26. Similarly, the leaf spring 48 is received in the opening 31 in the bottom plate of the body 26. Thus, the USB connector 25 is connected to the USB connector 22. In the USB connector 25, the moving piece 37 is positioned in the retracted position, so that interference with the support plate 44 of the USB connector 22 is avoided.

  In the notebook computer 11 as described above, the USB connector 22 includes the moving piece 51 arranged at the forward movement position based on the repulsive force of the second magnet 55. The moving piece 51 partially blocks the receiving port 43. As a result, entry of dust into the accommodation space of the main body 42 is avoided as much as possible. On the other hand, when the USB connector 25 is inserted into the USB connector 22, the moving piece 51 is pushed into the retracted position. Since the moving piece 51 moves along the conductive terminal 45, deformation or breakage of the conductive terminal 45 is reliably avoided. The elastic force of the conductive terminal 45 is reliably maintained. As a result, the conductive terminal 29 of the USB connector 25 can reliably contact the conductive terminal 45 of the USB connector 22. Moreover, since the movement of the moving piece 51 is realized based on the first and second magnets 54 and 55, the structure in the housing space of the main body 42 is simplified.

  Similarly, the USB connector 25 includes a moving piece 37 that is movable between a retracted position and an advanced position. The moving piece 37 can move freely according to the operation of the operating piece 35. The moving piece 37 moves along the conductive terminal 29 outside the conductive terminal 29. The deformation and breakage of the conductive terminal 29 can be avoided reliably. In this way, the user can scrape dust adhering to, for example, the conductive terminal 29 or the inner wall surface of the main body 26 with the moving piece 37 based on the operation of the operation piece 35. When the operation piece 35 moves to the front end position, the movement piece 37 is positioned at the forward movement position. Thus, the scraped dust is swept out from the receiving port 27 to the outside. As a result, dust remains in the USB connector 25.

  In the USB memory 23 as described above, the moving piece 37 may be always arranged at the front end position, for example. Thus, when the USB memory 23 is carried, the entry of dust into the housing space of the main body 26 is avoided. On the other hand, the moving piece 37 may be always arranged at the rear end position, for example. At this time, the main body 26 of the USB connector 25 may be covered with a cap (not shown). The cap only needs to completely close the receiving port 27 of the USB connector 25. In this way, entry of dust into the accommodation space of the main body 26 is avoided. Even if the user loses the cap, the moving piece 37 prevents the dust from remaining in the housing space of the main body 26.

  As shown in FIG. 12, a USB connector 25 a may be incorporated in the USB memory 23 in place of the USB connector 25 described above. In the USB connector 25 a, an elastic member, that is, a coil spring 56 is connected to the moving piece 37. The coil spring 56 is sandwiched between the rear end of the movable piece 51 and the front end of the housing 24. The coil spring 56 exhibits an elastic restoring force that pushes the moving piece 51 toward the front end position. As a result, the moving piece 51 is always arranged at the front end position. In this way, entry of dust into the accommodation space of the main body 26 is avoided. For example, when the USB connector 22 is connected, the movable piece 51 is positioned in the retracted position against the elastic restoring force of the coil spring 56 as shown in FIG. In addition, the same reference numerals are assigned to configurations and structures equivalent to those of the USB memory 23 described above.

  As shown in FIG. 14, a USB connector 25 b may be incorporated in the USB memory 23 instead of the USB connector 25 described above. The operation piece 35 described above is omitted from the USB connector 25b. A guide piece 61 is connected to the moving piece 37 described above. The guide piece 61 is disposed in the guide groove 34. Thus, the guide piece 61 guides the movement of the moving piece 37 between the forward position and the rear end position, as shown in FIG. A first magnet 62 is incorporated in the moving piece 37. A second magnet 63 is incorporated at the rear end of the main body 26. The first magnet 62 and the second magnet 63 repel each other. Like reference numerals are attached to the structure or components equivalent to those of the aforementioned USB connector 25.

  In such a USB connector 25b, as shown in FIG. 16, the moving piece 37 is arranged at the forward movement position based on the repulsive force of the second magnet 63. The moving piece 37 partially closes the receiving port 27. As a result, entry of dust into the accommodation space of the main body 26 is avoided as much as possible. On the other hand, when the USB connector 25 b is inserted into the USB connector 22, the moving piece 37 is pushed into the retracted position against the repulsive force of the second magnet 63 based on the contact with the support plate 44. As a result, the conductive terminal 29 of the USB connector 25 b can reliably contact the conductive terminal 45 of the USB connector 22. In addition, the same effects as described above are realized.

  As shown in FIG. 17, the notebook computer 11 may incorporate a USB connector 22 a instead of the USB connector 22 described above. In this USB connector 22a, a connecting piece 65 is connected to the moving piece 51. The connecting piece 65 extends rearward from the moving piece 51. For example, a cylindrical protrusion 66 is formed at the rear end of the connecting piece 65. The protrusion 66 is received in a guide groove 67 formed on the top plate of the main body 42. The guide groove 67 extends in the front-rear direction of the USB connector 22a. The protrusion 66 can move between the rear end position and the front end position of the guide groove 67. The movement of the moving piece 51 is realized based on such movement. In the USB connector 22a, the incorporation of the first magnet 54 and the second magnet 55 is omitted.

  An operation lever 68 is associated with the protrusion 66. For example, the operation lever 68 is slidably supported on the side plate of the main body 42. The sliding movement is realized between a first protruding position protruding from the main body casing 12 by a first length and a second protruding position protruding from the main body casing 12 by a second length smaller than the first length. An engaging member 69 is connected to the operation lever 68. The engaging member 69 swings around a support shaft 71 connected to the bottom plate of the main body 42. The engaging member 69 is engaged with the protrusion 66. The swing of the engaging member 69 is realized based on the sliding movement of the operation lever 68. Like reference numerals are attached to the structure or components equivalent to those of the aforementioned USB connector 22.

  In such a USB connector 22a, the operation lever 68 is positioned at the first protruding position. At this time, the projection 66 is positioned at the rear end position in the guide groove 67. The moving piece 51 is positioned at the retracted position. When the operating lever 68 is pushed into the main body housing 12, the operating lever 68 moves toward the second protruding position. The engaging member 69 swings around the support shaft 71 in accordance with the movement of the operation lever 68. As a result, as shown in FIG. 18, the protrusion 66 moves toward the front end position in the guide groove 67. Thus, the moving piece 51 is moved toward the forward position. When the operation lever 68 is positioned at the second protruding position, the protrusion 66 is positioned at the front end position. Thus, the moving piece 51 is positioned at the forward movement position. Based on the sliding movement of the moving piece 51, dust in the accommodation space of the main body 42 is swept out from the receiving port 43. In this way, dust remains in the main body 42.
