Description

  The present invention relates to a charging connection component and a charger that are used in a mobile terminal that does not have a charging connection portion that enables charging by contact, and that can be easily charged without requiring fitting.

  In recent years, high-performance portable terminals such as portable music terminals and smartphones that play music recorded by MP3 have been sold. In particular, since its sales, smartphones have shown high sales due to their ease of use and high functionality, and are being used by many consumers.

  These portable terminals have a terminal port used for connection with an external device, and a cable connected to the terminal port electrically connects the portable terminal and an external device such as a personal computer. For example, this cable transfers music data and image data between a portable terminal and a personal computer, or allows the portable terminal to be charged from the personal computer. Alternatively, the cable is connected to a charger that is separate from the mobile terminal, and the charger charges the mobile terminal via this cable. Here, these cables are often connected to an external device such as a personal computer or a charger via a USB connector.

  Here, the terminal port of the mobile terminal connected to the cable has a structure that requires the convex terminal and the concave terminal to be fitted to each other in order to connect the cable. In addition, since the USB connector is disposed at the end of the cable that is connected to the external device, the USB connector is also connected to the terminal port of the external device by fitting.

  In this way, portable music terminals and smartphones that have become widespread in recent years are supposed to perform data transfer and charging using the same cable (in order to measure the miniaturization and weight reduction of terminals, In order to perform charging, it is necessary to fit the terminal port of the mobile terminal and the cable.

  In this fitting, it is necessary to accurately fit the convex terminal and the concave terminal, which is troublesome. Further, if an operation error occurs in the fitting, the terminal may be bent or broken. If the terminal is bent, the portable terminal itself can be used, but data transfer and charging cannot be performed, and the portable terminal cannot be used without repair or replacement.

  In addition, unlike data transfer, charging needs to be performed frequently. Therefore, fitting the terminal port and the cable each time charging causes trouble and trouble as described above. Current portable music terminals and smartphones are assumed to perform frequent data transfers and updates, and it is assumed that it is assumed that charging will be sufficient for each data transfer or update. It is done.

  On the other hand, the user's desire to use these portable terminals mainly for calls and communications is also high. These users do not frequently transfer or update data, but often charge. In this way, it is very troublesome to fit the cable into the terminal port of the portable terminal for charging only. Of course, it may cause a failure of the terminal.

  Under such circumstances, various techniques have been proposed for chargers and charging devices that charge mobile terminals (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4).

JP 2000-152511 A JP 2006-262326 A JP 2010-109778 A JP 2010-154202 A

  Each of Patent Documents 1 to 4 discloses a charger and a charging device that charge a mobile terminal.

  Patent Document 1 discloses a charger that performs charging by installing a mobile phone and contacting a contact surface provided on the mobile phone with a terminal provided on a charging stand. Since the charger disclosed in Patent Document 1 does not require fitting for charging, it can solve the trouble of fitting and trouble. However, the charger disclosed in Patent Document 1 can be used only for a portable terminal having a contact surface that can be electrically connected by contact. A portable music terminal or a smartphone sold in recent years has only a terminal port that fits with a cable shared for charging and data transfer, and the charger of Patent Document 1 cannot be applied.

  Patent Document 2 is similar to Patent Document 1, and has a problem that cannot be applied to mobile terminals sold in recent years.

  Patent Document 3 discloses a technique for achieving both call and charging. This can be achieved with a cable that can be wound. However, like Patent Documents 1 and 2, the fitting cannot be omitted only for charging.

  Patent Document 4 is the same as Patent Documents 1 to 3.

It can be electrically connected.

  The connecting component for charging according to the present invention enables charging of the portable terminal only by contact without fitting (that is, only by placing the portable terminal on the charging stand). For this reason, troubles such as cable fitting connection in charging are reduced, and convenience for users mainly using communication, telephone calls, and the like is achieved. In particular, it is possible to easily charge a portable terminal in recent years that has only a terminal port that fits with a cable that is used for both data transfer and charging.

  In addition, unlike data transfer, it is not necessary to cause the cable and the terminal port to be fitted each time charging is likely to occur, so it is possible to prevent the terminal port terminal and the cable terminal from being deteriorated or broken down.

  As a result, the usability of portable music terminals and smartphones is improved, and the spread of these portable terminals is further promoted.

  (Embodiment 1)

(Reference example)
First, a reference example showing the prior art will be described with reference to FIG. FIG. 1 is a front view of a portable terminal showing a reference example in the first embodiment of the present invention. FIG. 1 is a front view, but only the fitting portion of the charging connector is shown in perspective in order to facilitate understanding of the fitting of the charging connector.

  The portable terminal 1 is a portable electronic device such as a portable music terminal, a portable image terminal, a cellular phone, a smartphone, a tablet terminal, an electronic book, and a portable game terminal. The mobile terminal 1 includes a terminal port 2 for charging, and a charging connector 5 is attached to the terminal port 2. Here, the terminal port 2 includes a concave terminal receiving port 3, and the charging connector 5 includes a convex terminal 4. The charging connector 5 is attached to the terminal port 2 by fitting the terminal receiving port 3 and the terminal 4 together.

  The charging connector 5 is connected to a cable 6, and a USB connector or the like is connected to the tip of the cable 6. When the USB connector is connected to an external charging device or a personal computer, power is supplied to the portable terminal 1 to be charged. The charging connector 5 and the cable 6 can perform not only charging but also data transfer.

  Thus, the charging of the portable terminal 1 in the prior art requires the fitting of the terminals each time. This fitting may loosen the fitting between the terminal receptacle 3 and the terminal 4 or may deteriorate the terminal receptacle 3 or the terminal 4. Naturally, it takes time and effort to fit, and it is troublesome to attach and remove. When it is necessary to perform data transfer, there is no problem in mounting and removing, but there is a problem that the mobile terminal 1 cannot always be charged for a user who mainly performs calls and communications. This is because it is very troublesome for the user to fit the terminal receptacle 3 and the terminal 4 each time charging is performed frequently.

  On the other hand, recent portable terminals have many fitting connectors 5 having a fitting structure as shown in FIG. 1 in order to share both data transfer and charging. This is because in data transfer, it is necessary to securely attach the terminal 4 by fitting in order to prevent an error due to lack of electrical connection or the like.

  As described above, in order to perform data transfer more reliably than charging, many of the mobile terminals 1 employ mounting of the charging connector 5 having a fitting structure. Such a portable terminal 1 is not capable of adequately dealing with a user who wants to frequently charge only.

(Overview)
The overall outline will be described with reference to FIG. FIG. 2 is a front view of the connection component for charging in the first embodiment of the present invention. Moreover, it demonstrates on the assumption that this connection component 10 for charging is used for the portable terminal 1 shown by FIG.

  The charging connection component 10 includes a housing 11, a connection portion 21, and a contact portion 31. The casing 11 has a structure, an aspect, and a size that can be connected to the mobile terminal 1 and can be installed on the charging stand. The housing 11 forms the basic outer shape of the connection component 10 for charging. The housing 11 includes a connection surface 20 that is connected to the mobile terminal 1 and a contact surface 30 that is a surface different from the connection surface 20.

  The connection portion 21 is provided on the connection surface 20 and can be fitted to the terminal port 2 of the mobile terminal 1 having a fitting structure. By connecting the connection portion 21 and the terminal port 2, the charging connection component 10 is attached to the mobile terminal 1. In addition, since many portable terminals sold in recent years are often connected to a charging connector that is used for both charging and data transfer in a fitting structure, the connection portion 21 can be fitted to the terminal port 2. The connecting component 10 for charging is connected to many portable terminals 1 easily and reliably.

  The contact part 31 is provided on the contact surface 30. The contact part 31 can be electrically connected to the electric terminal of the charging stand by contact. Since it can be electrically connected by contact, the connecting component 10 for charging can output the power supply from the charging stand to the mobile terminal 1.

  FIG. 3 shows a state of power supply from the charging stand due to the contact of the contact portion 31. FIG. 3 is a schematic diagram of a connecting component for charging connected to the charging stand according to Embodiment 1 of the present invention.

  The contact part 31 is in contact with the electrical terminal 41 provided in the charging stand 40 when the connecting component 10 for charging is installed on the charging stand 40. In FIG. 3, the plurality of contact sections 32 included in the contact portion 31 are in contact with the electrical terminals 41 corresponding to the positions of the contact sections 32. The front end of the electric terminal 41 has a surface, and the contact section 32 having a predetermined region comes into contact with this surface (including contact as a point and contact as a surface). Are electrically connected. At this time, as a matter of course, the electric terminal 41 and the contact portion 31 (particularly, the contact section 32) have conductivity.

  In this way, the connecting component 10 for charging is connected to the portable terminal 1 by the connecting portion 21 via the terminal port 2 having the fitting structure in the portable terminal 1, and the charging stand 40 based on the contact by the contact portion 31. And electrically connected. That is, charging can be performed by contacting the charging stand 40 while absorbing the fitting structure of the mobile terminal 1. In other words, the connection component 10 for charging according to the first embodiment can be attached to the portable terminal 1 having only the terminal port 2 having the fitting structure, and in actual charging such as installation on the charging stand 40. The mobile terminal 1 can be charged only by the contact by the contact portion 31 (that is, by simply placing the mobile terminal 1 to which the charging connection component 10 is connected on the charging stand 40).

  For this reason, as long as the charging connection component 10 is connected to the terminal port 2 of the portable terminal 1 (the cable or cord is not connected, the charging connection component 10 is connected to the portable terminal 1. If there is no inconvenience), it is sufficient to place the portable terminal 1 on the charging stand 40 when charging is desired. Since the contact portion 31 can be electrically connected to the electrical terminal 41 of the charging base 40 by contact, it is necessary to perform a fitting operation like a conventional charging connector for electrical connection for charging. There is no.

  As described above, the connecting component 10 for charging can reduce the trouble in charging the mobile terminal 1 and can prevent the terminal port 2 from being deteriorated due to repeated fitting.

(Usage mode)
An actual usage mode will be described.

  The charging connection component 10 is fitted to the terminal port 2 of the mobile terminal 1 by the connection portion 21. Since the connection is performed by fitting, the charging connection component 10 is fixed to the mobile terminal 1. FIG. 4 shows a state in which the charging connection component 10 is fixed to the mobile terminal 1. FIG. 4 is a front view of the mobile terminal to which the charging connection component according to Embodiment 1 of the present invention is connected.

  As shown in FIG. 4, since the charging connection component 10 is fixed to the mobile terminal 1, the charging connection component 10 is connected to a part of the mobile terminal 1. A part of the mobile terminal 1 protrudes due to the charging connection component 10, but there is no problem in using and storing the mobile terminal 1. Of course, since the connection component 10 for charge interposes the charging stand 40 and the portable terminal 1, the power cable and the communication cable are not connected. For this reason, even if the connection component 10 for charge is connected to the portable terminal 1, a user does not feel inconvenience in particular.

  In particular, the state shown in FIG. 4 in which the mobile terminal 1 can be immediately charged is preferable for a user who wants to frequently perform charging caused by a call or communication rather than data transfer.

  The mobile terminal 1 in the state of FIG. 4 is in a charging operation state only by being placed on the charging stand 40. FIG. 5 is a front view illustrating a state in which the mobile terminal is installed on the charging stand according to Embodiment 1 of the present invention. The mobile terminal 1 to which the charging connection component 10 is connected is placed on the charging stand 40 (having the charging electrical terminal 41 and has a shape and size that can accommodate a part of the mobile terminal 1). Then, the portable terminal 1 is charged through the charging stand 40 due to the contact between the contact portion 31 and the electric terminal 41.

  The contact portion 31 includes a contact section 32 having conductivity, and the contact section 32 is located at a position facing the electrical terminal 41 of the charging base 40 having conductivity. When the charging connection component 10 is placed on the charging stand 40 together with the portable terminal 1, the contact section 32 and the electric terminal 41 are naturally in contact with each other and are electrically connected. By this electrical connection, the charging connection component 10 electrically connects the charging stand 40 and the portable terminal 1. As a result of this connection, the mobile terminal 1 is charged by the charging stand 40.

  The installation of the portable terminal 1 on the charging stand 40 is easily performed by the user, and does not require labor such as fitting and removal. For this reason, the operation | work at the time of charge is efficient, and a user can charge frequently. As a result, the occurrence of insufficient charging of the mobile terminal 1 is prevented, and the usability of the mobile terminal 1 is further enhanced for the user.

(Details of each part)
Next, the detail of each part is demonstrated.

(Casing)
The housing 11 forms the outer shape of the charging connection component 10. The casing 11 is connected to the portable terminal 1 and has a shape and size that can be installed on the charging stand 40. For example, the configuration is based on a square or a polygon and is smaller than the mobile terminal 1.

  Although the housing | casing 11 should just be formed with raw materials, such as resin, a metal, and an alloy, it is preferable to form with resin from the usability.

  Moreover, since the housing | casing 11 is solid, it has a some surface. The housing 11 has a connection surface 20 having a connection portion 21 connected to the terminal port 2 of the mobile terminal 1 and a contact surface 30 that is a surface different from the connection surface 20. The connection surface 20 and the contact surface 30 are suitably located at positions that oppose each other, but the contact surface 30 may be provided at a position that does not face the connection surface 20 such as a position bent by 90 degrees. A connection portion 21 is formed on the connection surface 20 of the housing 11, and a contact portion 31 is formed on the contact surface 30.

  The housing | casing 11 may be provided with the display part which shows a charge condition. FIG. 6 is a front view of the charging connection component according to Embodiment 1 of the present invention. The charging connection component 10 shown in FIG. 6 includes a display unit 12 on the surface of the housing 11. The display unit 12 is provided in the housing 11, not the mobile terminal 1 or the charging stand 40. The display unit 12 indicates the state of charge. For example, the display unit 12 indicates states such as “charging is sufficient”, “charging is insufficient”, “charging”, and the like.

  Conventionally, the display indicating the state of charge is often provided on the mobile terminal 1 itself or the charging stand 40. However, the display screen of the mobile terminal 1 is blacked out when not in use. However, it is difficult for users to understand. On the other hand, if the display unit 12 is provided in the casing 11 of the connection component 10 for charging, the user can always check the state of charge, so that the usability is improved.

  By connecting the connection portion 21 with the terminal port 2, the charging connection component 10 and the portable terminal 1 are electrically connected. As a result of this electrical connection, the charging connection component 10 can receive various electrical signals from the mobile terminal 1, so that the display unit 12 can grasp and display the state of charge of the mobile terminal 1.

(Connection part)
The connection portion 21 is fitted to the terminal port 2 of the mobile terminal 1 provided on the connection surface 20. By this fitting, the charging connection component 10 and the portable terminal 1 are electrically connected. The connection portion 21 includes a plurality of protruding terminals 22 as shown in FIG. In FIG. 6, only a part of the plurality of protruding terminals is provided with a reference numeral, but this gives priority to the visibility of the drawing, and the protrusion of the connection portion 21 shown in FIG. All are protruding terminals 22.

  The terminal port 2 of the portable terminal 1 has a terminal receiving port 3 (shown in FIG. 1). The protruding terminal 22 is fitted by being inserted into the terminal receiving port 3. That is, the connection portion 21 is connected to the portable terminal 1 by fitting the protruding terminal 22 and the terminal receptacle 3.

  It is preferable that the protruding terminal 22 and the terminal receiving port 3 have a symmetrical shape that is uneven in order to fit. That is, if the protruding terminal 22 is a cylinder, the terminal receptacle 3 has a recess corresponding to the cylinder. Of course, the shape is not limited to these as long as the fitting is possible.

  Further, the number of the protruding terminals 22 and the terminal receptacles 3 are preferably equal, but the number of the protruding terminals 22 may be smaller than the number of the terminal receptacles 3. The terminal port 2 of the portable terminal 1 has a terminal port 3 corresponding to various electric signals related to data transfer as well as charging. On the other hand, since the connection part 21 of the connection component 10 for charge should just be able to charge at least, the protrusion terminal 22 should just need only the number required for charge. For this reason, the number of the protruding terminals 22 and the number of the terminal receptacles 3 may be inconsistent.

  Of course, the shape of the housing 11 is preferably set so that the positions of the protruding terminals 22 and the terminal receptacles 3 have a corresponding relationship.

(Contact part)
The contact portion 31 is provided on the contact surface 30 of the housing 11.
When the mobile terminal is installed on the charging stand 40, the contact unit 31 realizes an electrical connection with the charging stand 40 by contact. Since the electrical connection is realized only by contact, the user is not bothered by extra work such as fitting and mounting during charging.

  As shown in FIG. 3 and FIG. 4, the contact portion 31 has a plurality of contact sections 32. In FIGS. 3 and 4, only some of the contact sections are denoted by reference numerals in order to prioritize the visibility of the drawings. Similar elements without symbols are also contact sections 32.

  The contact part 31 implement | achieves an electrical connection by making this contact division 32 contact the electrical terminal 41 of the charging stand 40. FIG. The contact section 32 may be a section where metal or alloy is plated and applied, or a section where a metal plate is attached. As a result, the contact section 32 becomes a conductive region.

  The plurality of contact sections 32 are provided at positions corresponding to the electrical terminals 41 of the charging stand 40. In particular, when the charging connection component 10 (the portable terminal 1 to which the charging connection component 10 is attached) is installed on the charging stand 40, the plurality of contact sections 32 come into contact with the electrical terminals 41 at the same position. The electrical terminal 41 also has conductivity, and the contact section 32 and the electrical terminal 41 are electrically connected by contact between the contact section 32 and the electrical terminal 41. With this electrical connection, the mobile terminal 1 and the charging stand 40 are electrically connected.

  At this time, the contact section 32 is a surface, and the electrical terminal 41 has a protruding shape. Since only the protruding electrical terminal 41 comes into contact with the contact section 32 which is this surface, the user simply installs the portable terminal 1 to which the charging connection component 10 is connected on the charging stand 40, and the electrical connection by this contact is made. Can be generated.

  The plurality of contact sections 32 can be electrically connected to at least one of a charging terminal, a charging ground terminal, a data transmission terminal, a data reception terminal, a signal synchronization terminal, and a control signal terminal among the electrical terminals 41 by contact. It is. That is, when the portable terminal 1 to which the charging connection component 10 is connected is installed on the charging stand 40, the charging terminal, the charging ground terminal, the data transmission terminal, the data reception terminal, the signal synchronization terminal, At least one terminal of the control signal terminal and the contact section 32 are electrically connected. By this electrical connection, the charging connection component 10 connects the charging stand 40 and the portable terminal 1 with a predetermined function according to the function of each terminal.

  Further, since the charging connecting component 10 needs to be charged at least, the contact portion 31 has a contact section 32 that always contacts the charging terminal and the charging ground terminal among the electric terminals 41. It is necessary to be. In other words, the contact section 32 may not be provided at a position corresponding to the electric terminal other than the charging terminal and the charging ground terminal.

  Of course, when the charging stand 40 has not only charging but also functions such as data transfer, the contact section 32 corresponding to the data transmission terminal and the like is provided, and the portable terminal 1 is simply installed on the charging stand 40. In addition to charging, data transfer is performed. On the other hand, for a user who wants to frequently charge, charging is executed simply by placing the mobile terminal 1 on the charging stand 40, so there is no extra effort.

  It is also preferable that the contact section 32 is recessed from the periphery on the contact surface 30. The surface of the contact section 32 needs to be in electrical contact with the electrical terminal 41. If the contact section 32 is recessed from the surroundings, the contact with the electric terminal 41 is likely to be ensured, and this need is easily met. In particular, if the contact section 32 is recessed, the position of the electrical terminal 41 and the contact section 32 can be easily aligned, and reliable contact can be obtained.

  Of course, the contact section 32 is recessed, so that not only the contact with the electric terminal 41 is ensured, but also the contact section 32 is convex and the electric terminal 41 is concave, thereby ensuring the contact. good.

  It is also preferable that the contact section 32 has an elastic force that can apply pressure to the electrical terminal 41. The contact section 32 and the electrical terminal 41 are electrically connected only by contact. Normally, the charging stand 40 is placed on the floor (such as on a desk), and the mobile terminal 1 is placed from above the charging stand 40. Therefore, the contact section 32 is subjected to gravity pressure. Yes. It is considered that the contact section 32 and the electric terminal 41 are in contact with each other with sufficient contact pressure due to the gravity. However, depending on how the mobile terminal 1 is installed, it is assumed that sufficient pressure is not applied. Therefore, when the contact section 32 has an elastic force, the contact pressure with the electric terminal 41 is further increased by the elastic force.

  When the contact pressure between the contact section 32 and the electrical terminal 41 increases due to the elastic force, the electrical connection between the contact section 32 and the electrical terminal 41 is strengthened, and an error is less likely to occur in the exchange of electrical signals during charging.

  The elastic force is realized by attaching a spring or a coil to the back surface of the metal plate that forms the contact section 32. Or it is also suitable that the electric terminal 41 has elastic force. For example, a spring or a coil is attached to the bottom surface of the electric terminal 41, and the electric terminal 41 generates an elastic force by the spring or the coil. Even when the electrical terminal 41 has an elastic force, the contact pressure between the contact section 32 and the electrical terminal 41 is increased, so that there is an advantage that the reliability of electrical connection is increased. As described above, since at least one of the contact section 23 and the electric terminal 41 has an elastic force, the electrical connection between the contact portion 31 and the charging stand 40 is ensured.

  It is also preferable that at least one of the contact section 32 and the electric terminal 41 has a magnetic force. This is because by having the magnetic force, the physical connection between the contact section 32 and the electric terminal 41 is ensured, and the electrical connection is ensured. Since each of the contact section 32 and the electric terminal 41 needs to have conductivity, it is formed of a metal or an alloy. Such a metal or alloy can naturally be processed to have a magnetic force. Here, the contact section 32 may have a magnetic force directly depending on the material or structure of the contact section 32 itself, or the contact section 32 may be indirectly connected by a material (such as a member inside the housing) around the contact section 32. It may also have a magnetic force. Of course, the contact section 32 does not have a magnetic force, and the electrical terminal 41 has a magnetic force, so that the contact can be ensured.

  For example, when the shape of the charging base 40 is deformed due to aging, the mobile terminal 1 to which the charging connection component 10 is connected may not be correctly installed on the charging base 40. For example, the mobile terminal 1 is installed on the charging stand 40 in an oblique state. In this case, a part of the contact section 32 and the electric terminal 41 may be insufficiently contacted. Even in such a case, when at least one of the contact section 32 and the electrical terminal 41 has a magnetic force, the contact force is increased by the magnetic force.

  When at least one of the contact section 32 and the electrical terminal 41 has a magnetic force, the contact (connection) is naturally more reliably ensured by the magnetic force even when the connecting component 10 for charging is mounted on the charging base 40.

  Alternatively, when the contact section 32 has a magnetic force, the mobile terminal 1 is not only installed on the charging stand 40 but can be charged only by connecting a charging cord to the mobile terminal 1. FIG. 7 is a front view of the portable terminal to which the charging cord according to Embodiment 1 of the present invention is connected. The charging cord 50 includes a connector 51, a cable 53, and a socket 54. For example, when carrying out the mobile terminal 1 or going out on a business trip, carrying around the charging stand 40 is difficult. In many cases, it is desirable to charge the portable terminal 1 while carrying only the charging cord 50. On the other hand, since the connecting component 10 for charging is only electrically connected to a member having a charging function such as the charging base 40 by contact by the contact portion 31, it is difficult to physically connect it to a normal charging cord.

  When the contact section 32 has a magnetic force, it is connected to the electrical terminal 52 of the connector 51 of the charging cord 50 by the magnetic force. That is, the contact section 32 and the electrical terminal 52 of the charging cord 50 can be physically connected by simple contact without requiring fitting. This is as shown in FIG. The contact section 32 and the electrical terminal 52 are not fitted, but are physically connected by magnetic force. The user can charge the portable terminal 1 only by inserting the socket 54 of the charging cord 50 into the power source.

  As described above, the charging connecting component 10 is fitted to the portable terminal 1 and contacts using the magnetic force to the charging cord 50, thereby reducing the effort of the user and the portable terminal. 1 can be charged. In the case of being connected by magnetic force, it is possible to create a state in which the charging cord 50 is hung on the charging connection part 10. In this case, charging can be performed by simply inserting the socket 54 into the power source. Become.

  Of course, the electrical connection provided by the magnetic force may be realized by the electric terminal 51 included in the charging cord 50 having the magnetic force.

(Function switching)
Here, when the mobile terminal 1 to which the charging connection component 10 is connected is installed on the charging stand 40, the user wants to charge the mobile terminal 1. This is because a data transfer cable is often attached to the terminal port 2 when data transfer is desired. For this reason, when the portable terminal 1 to which the connection component for charging 10 is connected is installed on the charging stand 40, at least one of the data transmission terminal, the data reception terminal, the signal synchronization terminal, and the control signal terminal is operated. May be stopped. This is because power saving is achieved by stopping the operation. At this time, functions corresponding to these terminals to be stopped may be stopped on the charging stand 40 side, and functions corresponding to these terminals to be stopped may be stopped on the mobile terminal 1 side.

  Alternatively, when the charging connection component 10 is connected to the charging cord 50 as shown in FIG. 7, at least one of a data transmission terminal, a data reception terminal, a signal synchronization terminal, and a control signal terminal that is not directly related to charging. One may stop the operation. For example, the mobile terminal 1 recognizes that the charging connection component 10 is connected to the mobile terminal 1, and the mobile terminal 1 has at least one of a data transmission terminal, a data reception terminal, a signal synchronization terminal, and a control signal terminal. This is achieved by stopping the function.

  As described above, the charging connection component 10 is an optimal member for a user who frequently performs charging. Therefore, in consideration of power saving, at least the data transmission terminal, the data reception terminal, the signal synchronization terminal, and the control signal terminal are used. It is also preferred that one function is stopped.

  Since the connecting member 10 for charging in the first embodiment does not require a fitting operation, it can efficiently provide a frequently occurring charging operation while reducing labor and deterioration.

  (Embodiment 2)

Next, a second embodiment will be described.
As shown in FIG. 2, the charging connection component 10 is an independent member connected to the mobile terminal 1. However, in recent mobile terminals 1, a cover is often attached to the outer surface in order to improve and protect the feeling of use. For example, in the case of a smartphone, a cover made of silicon or resin that covers the outer periphery and the back surface other than the liquid crystal screen may be attached. The connecting member 10 for charging may be attached so as to be integrated with the cover, or may be integrally formed from the beginning.

  FIG. 8 is a front view of the mobile terminal according to Embodiment 2 of the present invention. FIG. 8 shows a state in which the mobile terminal 1 is viewed from the front. A cover 15 is attached to the outer periphery of the mobile terminal 1. The cover 15 has a material such as silicon or resin, and protects the mobile terminal 1 from impact or deterioration due to use. In FIG. 8, it seems that the cover 15 covers the outer periphery of the mobile terminal 1, but it may cover the back surface of the mobile terminal 1. Of course, the front surface (display surface) of the portable terminal 1 may be covered.

  The charging connection component 10 may be attached so as to be integrated with the cover 15 or may be previously formed in an integral structure. Since the cover 15 is used by being mounted on the mobile terminal 1, if the charging connection component 10 is integral with the cover 15 (either integrally attached or integrally formed), the user attaches the cover 15, There exists an advantage which can connect the connection component 10 for charge. In particular, when the cover 15 and the charging connection component 10 are integrated, the user can connect the charging connection component 10 by attaching the cover 15, and thus the mobile terminal 1 can be easily charged. it can.

  In this case, as shown in FIG. 8, the casing 11 of the charging connection component 10 may protrude to the outside of the cover 15, or the casing 11 may be configured to coincide with the outer periphery of the cover 15. May be. In this case, there is an advantage that the mobile terminal 1 can be easily placed on the charging stand 40. Further, since the charging connection component 10 and the cover 15 are integrated, there is a merit that the charging connection component 15 is prevented from falling off.

  As described above, since the charging connection component 10 is integral with the cover 15 of the mobile terminal 1, the charging connection component 10 can be connected in accordance with the mounting of the cover 15 on the mobile terminal 1.

In addition, the charging stand 40 includes an electrical terminal 41 that electrically connects the charging stand 40 and the portable terminal 1 by contact with the contact section 32 (contact portion 31) of the connection component 10 for charging.

  By connecting the charging connection component 10 to the charging stand 40 (of course, by installing the portable terminal 1 to which the charging connection component 10 is connected), the charging stand 40 and the portable terminal 1 are electrically connected. Since it is connected, the charger 100 can charge the mobile terminal 1 through the charging stand 40. In addition, as described in the first and second embodiments, the contact section 32 of the charging connection component 10 and the electrical terminal 41 of the charging stand 40 are only electrically connected by contact, so that the user can fit them. There is no need to spend time.

  For this reason, the charger 100 reduces the user's effort, reduces the deterioration of the terminal port 2 included in the mobile terminal 1, and enables the mobile terminal 1 to be charged. That is, the charger 100 can provide a benefit for a user who frequently performs charging.
