Description

  The present invention relates to a charging device that is attached to a portable device containing a secondary battery and charges the built-in secondary battery.

The charging device includes positive and negative contact terminals that are in contact with a power supply terminal of a mobile device to be mounted. When a metal contacts the positive and negative contact terminals and shorts, a large short current flows. In addition, when the voltage of the positive and negative contact terminals is high, there is a possibility of electric shock when touching with a wet hand. Even if the voltage is low, there is a risk of low temperature burns if contacted for a long time. In order to eliminate this harmful effect, a charging device has been developed in which a contact terminal is accommodated in a case when a portable device is not attached (see Patent Document 1).

  The charging device described in this publication is shown in FIGS. The charging device includes a case 31 having a concave mounting portion 32 that fits and mounts the mobile device 40, a mounting detection unit 30 that detects that the mobile device 40 is mounted on the mounting portion 32, and the mobile device 40. Is attached to the mounting portion 32, and is provided with a pair of output terminal portions 33A for contacting a power supply terminal 41 provided in the portable device 40 and applying a charging voltage to a secondary battery built in the portable device 40. . The output terminal portion 33 </ b> A is disposed in the case 31 and is provided so as to be able to protrude and retract from the terminal portion 35 provided in the case 31 to the mounting portion 32. The mounting detector 30 is pivotally supported in the case 31, and a tilting body 34 in which a protruding portion 37 at one end passes through a through hole 36 provided in the bottom surface of the mounting portion 32, and a protruding portion 37 of the tilting body 34. And a spring wire 33 for urging the projection in the protruding direction. When the portable device 40 is mounted and one end of the tilting body 34 is pushed down against the urging force of the spring wire 33, the output terminal portion 33A is moved from the terminal window 35 to the mounting portion 32 in conjunction with the rotation of the tilting body 34. Extrude and contact with the power terminal 41 of the portable device 40.

  Furthermore, this charging device divides the tilting body 34 of the mounting detection unit 30 into left and right parts and independently supports them. By pressing the left and right tilting bodies 34, the output terminal portion 33A is pushed out from the terminal window 35 to the mounting portion 32. Since the charging device of this structure independently tilts the individual tilting bodies 34 divided into the left and right, only when one end of the left and right tilting bodies 34 is pushed down against the biasing force of the spring wire 33 at the same time, Two output terminal portions 33A protrude from the terminal window 35 to the mounting portion 32. When the portable device 40 is attached to the attachment portion 32, the left and right tilting bodies 34 are pushed down by the portable device 40, and the battery built in the portable device 40 is charged by the projecting positive and negative output terminal portions 33A. The However, when the mobile device is not attached, the output terminal portion does not protrude from the attachment portion unless the user pushes down one end of the left and right tilting bodies simultaneously. For this reason, an electric shock or a short circuit can be reliably prevented.

  However, since the charging device of this structure is a mechanism in which the tilting body is divided into left and right and tilts independently, the positive and negative output terminal portions protrude only when both protruding portions are pressed. There is a drawback that the mechanism becomes complicated. In addition, when one tilting body is tilted, one output terminal portion protrudes from the mounting portion, and therefore, there is a drawback that it is impossible to reliably prevent the protruding output terminal portion from being contaminated or deformed.

The present invention has been developed with the object of eliminating this drawback. An important object of the present invention is to provide a charging device capable of projecting an output terminal portion to a mounting portion only when a pair of projecting portions are pushed with an extremely simple structure.

In this structure, since the seesaw piece 15 can be elastically pushed out by the tilting body 4, it is not necessary to provide a dedicated part in order to push out the seesaw piece 15 elastically. Further, the protruding portions 7 provided on both sides of the seesaw piece 15 can always reliably protrude out of the case 1 from the through hole 6 of the mounting portion 2. Here, when the portable device 25 is mounted, the projecting portion 7 and the seesaw piece 15 are pushed down, and the tilting body 4 rotates, whereby both elastic pieces 22 integrally formed with the tilting body 4 also rotate. The elastic piece 22 is designed to be away from the lower ends of both end portions of the pushed-out seesaw piece 15 so that the elastic piece 22 is downward. As a result, the elastic piece 22 bends for a long time when the portable device 25 is mounted. The seesaw piece 15 is not pushed up. However, the charging device of the present invention does not necessarily require the seesaw piece to be pressed from below with an elastic body so that the protruding portion protrudes outside the case. This is because the seesaw piece can be pushed up by the pressing portion of the tilting body.

  The seesaw piece 15 does not push down the pressing portion 4 </ b> A of the tilting body 4 in a state where the portable device 25 is not mounted on the mounting portion 2, that is, in a state where the protruding portions 7 at both ends protrude from the mounting portion 2. In this state, the tilting body 4 is urged by the tilting spring 18 so that the output terminal portion 3A is in the retracted position in the case 1 as indicated by the solid line in FIG. In addition, in a state where one projecting portion 7 of the seesaw piece 15 is pushed into the case 1 and the other projecting portion 7 is projected to the mounting portion 2, the seesaw piece 15 simply tilts, and the tilting body 4 is not pushed down. Accordingly, even in this state, the output terminal portion 3 </ b> A is a retracted position in the case 1.

  However, when the portable device 25 is attached to the attachment portion 2 and both the protruding portions 7 at both ends of the seesaw piece 15 are pressed together, the entire seesaw piece 15 is pushed down. In this state, the seesaw piece 15 pushes down the pressing portion 4A of the tilting body 4 on the lower surface at the center. The tilting body 4 whose pressing portion 4A is pushed down tilts so that the output terminal portion 3A is pushed out of the case 1. The output terminal portion 3A pushed out of the case 1 from the terminal window 5 is pressed and electrically connected to the power terminal 26 of the portable device 25 set in the mounting portion 2. In this state, since the output terminal portion 3A is pushed by the power supply terminal 26, the contact coil portion 3C is deformed so as to separate the stopper portion 3a from the terminal connecting portion 10 and the output terminal portion 3A becomes the power supply terminal 26. Press elastically.

  The lever piece 16 is integrally formed of plastic as a whole. As shown in the plan view of FIG. 15, the lever piece 16 is formed in a U shape so that a pair of arms 16B are connected in parallel to both sides of the upper and lower pieces 16A. . A protruding portion 7 that protrudes from the case 1 to the mounting portion 2 is provided in the middle of the arm 16B. A connecting shaft 16C is integrally formed at the tip of the arm 16B. The connecting shaft 16C is connected to the case 1 so as to be rotatable. The connecting shaft 16C protrudes on both sides of the arm 16B. The connecting shaft 16C is guided to a connecting hole (not shown) provided between the upper case 1A and the lower case 1B and is connected to the case 1 so as to be rotatable.

  In the charging device shown in FIG. 15, the tilting body 4 is arranged at the left end in the case 1. The lever piece 16 has the upper and lower pieces 16A arranged above the pressing portion 4A of the tilting body 4 and the posture in which the tip of the arm 16B is located on the right side of the upper and lower pieces 16A, that is, on the opposite side of the tilting body 4. It is placed inside. That is, in the charging device shown in the figure, the tilting body 4 and the lever piece 16 are arranged in the longitudinal direction (= extending direction) of the elongated case 1. Since the tilting body 4 is tilted by the lever piece 16, the upper and lower pieces 16A of the lever piece 16 and the pressing portion 4A of the tilting body 4 are arranged vertically and connected. The lever piece 16 is disposed at a position where the tilting body 4 is tilted so that the upper and lower pieces 16 </ b> A push down the pressing portion 4 </ b> A so that the output terminal portion 3 </ b> A can contact the power supply terminal 26 of the portable device 25.

  In the charging device of FIG. 15, the circuit board 13 is arranged in a region surrounded by the upper and lower pieces 16 </ b> A and the arm 16 </ b> B of the lever piece 16 and fixed to the case 1. The spring wire 3 is soldered and fixed to both sides of the circuit board 13. The circuit board 13 connects the connector receiving part 23. The circuit board 13 is arranged and fixed at a fixed position of the case 1 via the connector receiving portion 23. The connector has terminals (not shown) exposed outside the case 1. The connector is connected to a charging power source disposed outside the case 1 via a lead wire (not shown).

  In the charging device of FIGS. 15 to 18, when the portable device 25 is mounted on the mounting portion 2 of the case 1, the protruding portion 7 protruding to the mounting portion 2 is pushed. That is, the lever piece 16 is tilted by the portable device 25. The lever piece 16 tilted in this state moves the upper and lower pieces 16A downward. Since the upper and lower pieces 16A are above the pressing part 4A of the tilting body 4, the pressing part 4A of the tilting body 4 is pushed down to tilt the tilting body 4. The tilting body 4 tilted in this posture causes the output terminal portion 3 </ b> A to protrude from the mounting portion 2 and contact the power supply terminal 26 of the portable device 25.

  In a state where the portable device 25 is not attached to the attachment part 2, the pressing part 4 </ b> A of the tilting body 4 pushes up the upper and lower pieces 16 </ b> A of the lever piece 16. This is because the tilting body 4 is biased by the tilting spring 18. When the upper and lower pieces 16 </ b> A are pushed up, the lever piece 16 causes the protrusion 7 to protrude from the mounting portion 2. In this posture, the tilting body 4 sets the output terminal portion 3 </ b> A to the retracted position in the case 1.

  In the second embodiment, the lever piece 16 is used to increase the distance between the protruding portion 7 and the output terminal portion 3A. As shown schematically in FIG. 17 when the portable device 25 is mounted, the power terminal 26 located at one end of the portable device 25 is first brought into contact with the mounting portion 2 and then the other end of the portable device 25 is connected to the mounting portion 2. Since it will be abutted and mounted, the protrusion 7 will be lowered at the end of the mounting of the portable device 25, and the protrusion of the output terminal portion 3A and the contact with the power terminal 26 will also be at the end of the mounting. Become. If the distance between the projecting portion 7 and the output terminal portion 3A is small as in the first embodiment, the projecting portion 7 is lowered at the beginning when the portable device 25 is mounted, and the output terminal from the beginning. Since the portion 3A protrudes and comes into contact with the power terminal 26, the power terminal 26 and the output terminal portion 3A are rubbed for a long time until the mounting operation is completed. Since the output terminal portion 3A protrudes and comes into contact with the power supply terminal 26, it is possible to reduce the friction between the power supply terminal 26 and the output terminal portion 3A over a long time.

  In the second embodiment, as shown in the comparative diagram of FIG. 19, it is assumed that the right end of the tilting body 4 is extended and the protruding portion 7 is provided without using a lever piece. If the movement of the tilting body 4 is the same as that of the second embodiment described above, the distance between the projecting portion 7 and the tilting shaft 8 increases (in FIG. 19, various positions of the projecting portion 7 are shown. The vertical movement distance associated with the rotational movement of the protrusion 7 is increased, and the distance between the protrusion 7 and the tilting shaft 8 is restricted so that the vertical movement distance of the protrusion 7 is a desired distance. Will receive. However, in the second embodiment, by using the lever piece 16, the vertical distance of the protruding portion 7 can be made appropriate without receiving such a restriction.

  20 is a cross-sectional view showing another example of the output terminal portion 3A and the like of the second embodiment, which is the same as the cross-sectional portion of FIG. 18, and the same structure is denoted by the same reference numeral. Description is omitted. In FIG. 20, the contact connecting portion 4B of the tilting body 4 does not have a vertical portion, and the spring wire 3 extends from the contact coil portion 3C to bend the convex output terminal portion 3A. After forming, it returns so as to be folded back, and the terminal end 3F is engaged with the lower portion at the end of the flat portion 4Ba and held. In this structure, since the portion of the output terminal portion 3A is formed by two of the spring wires 3, the elastic force of the output terminal portion 3A can be increased.
