Thus, a second terminal Z2c that contacts the switch operation terminal of the charging input side contact member b2 in the connection terminal b1 of the mobile phone b is provided.

Further, the terminal main bodies 8, 9, 10 in the conversion connector 4 are fixed by being fitted into mounting grooves 12 carved into the support body 11 attached in the housing 7.
That is, the terminal main bodies 8, 9, and 10 are integrally formed as shown in FIG. 9, and the three mounting grooves 12, so that the width directions of the terminal main bodies 8, 9, and 10 correspond to each other. 12 and 12 are provided according to the arrangement pattern of the models X, Y, and Z of the mobile phones b, b, and b.

By fitting into the mounting groove 12 from above, a terminal body 13 in which the plus terminal 8, the minus terminal 9, and the switch operation terminal 10 are set as shown in FIG. 10 is formed.
In forming the terminal body 13, since automatic assembly is performed mechanically, the plus terminal 8, the minus terminal 9, and the switch operation terminal 10 that are easily damaged by a slight malfunction should be easily and reliably assembled. In addition, since no troublesome work such as soldering is required as in the prior art, the workability is greatly improved and the cost can be reduced.

  The conversion connector 4 is detachably provided in an attachment port (see FIG. 11) 14 provided in the case main body 1 so that the main body member 15 of the case main body 1, the charging battery 2 and the circuit board 3 is carried. The telephone sets b, b, and b can be used together with the models X, Y, and Z. That is, the conversion connectors 4 for different models X, Y, and Z can be replaced.

Although not shown, a plurality of mounting grooves 12 carved in the support 11 mounted in the housing 7 can be provided at intervals, and a plurality of mobile phones having different models X, Y, and Z are provided. By selectively fitting the terminal main bodies 8, 9, 10 to the above-mentioned several mounting grooves 12, 12... Corresponding to the mounting position of the charging input side contact member b 2 of the connection terminal b 1 in the telephone b. One type of support 11 can be used in combination.
Further, as shown in FIG. 7 and the like, one side portion of the housing 7 is connected to the connecting portions 16x, 16y, and 16z corresponding to the shape of the connecting terminal b portion for each of the models X, Y, and Z in the plurality of mobile phones b. To form.

  Therefore, the mobile phone charging apparatus A according to the embodiment of the present invention configured as described above corresponds in advance to, for example, the connection terminals b of a plurality of mobile phones b of different models X, Y, and Z (three types). Thus, as shown in FIG. 7, three types of conversion connectors 4, 4, and 4 are manufactured.

  Further, on the main body member 15 side, the first plus terminals X1a, Y1a, Z1a and the first minus terminals X1b, Y1b, Z1b and the terminals of the terminal main bodies 8, 9, 10 in the three types of conversion connectors 4, 4, 4 and the terminals. As shown in FIGS. 5, 5, etc., the positive electrode 5a, the negative electrode 5b and the contact 5c corresponding to any of X1c are formed on the circuit board 3.

When the model is CDMA (product name) with respect to the main body member 15 thus formed, the conversion connector 4 having the configuration shown in FIG. 7A is selected, and as shown in FIG. The housing 7 is inserted into the attachment port 14 so that the connection portion 16x is positioned on the outer side.
Then, as shown in FIG. 1, the conversion connector 4 has the housing 7 fitted into the mounting opening 14, and the first plus terminal X1a, first minus terminal X1b, As shown in FIG. 3, the switch operation terminal X1c engages with the positive electrode 5a, the negative electrode 5b and the contact 5c on the circuit board 3 and reliably contacts them.

  Therefore, the current of the charging battery 2 in the case main body 1 is ready to flow from the second plus terminal X2a, the second minus terminal X2b, and the switch operation terminal X2c in the terminal main bodies 8, 9, and 10.

  In this state, when it is inserted into the connection terminal b1 of the mobile phone b for CDMA (trade name) X, the charging input side contact members b2, b2, b2 of the connection terminal b1 are connected to the second terminals 9, 9, 10. Since the plus terminal X2a, the second minus terminal X2b, and the switch operation terminal X2c are connected and become energized, the current of the charging battery 2 of the case body 1 flows to the body battery of the mobile phone b and charging with a predetermined voltage is performed. Made.

  When the model is the PDC type Y, the conversion connector 4 having the configuration shown in FIG. 7B is selected, and when the model is the FOMA (product name) Z type, the conversion connector 4 is selected as shown in FIG. 11 is selected, and the housing 7 is inserted into the attachment port 14 of the case body 1 so that the connecting portions 16y and 16z are positioned on the outer side, as shown in FIG. (Product Name) The main battery can be charged by the charging battery 2 in the same manner as the mobile phone b for X.

  When attaching / detaching these conversion connectors 4, the first plus terminal, the first minus terminal, and the switch operation terminal are inserted into the circuit board 3 and released from the insertion, so-called the attachment port 14 of the conversion connector 4. Since it is a simple operation performed by pushing and pulling with the mounting opening 14 as a guide, it is excellent in operability and no erroneous operation occurs.

In addition, the main body member 15 comprising the case main body 1 and the charging battery 2 and the circuit board 3 is provided with one type that can be used in common for all three types of conversion connectors 4, 4, and 4. Therefore, it is not necessary to manufacture each model X, Y, Z.
Furthermore, since the conversion connectors 4, 4 and 4 are simply structured to simply change the mounting positions of the terminal main bodies 8, 9, and 10 on the support 11, they can be manufactured as small and easy as possible, resulting in a significant cost reduction. Can be achieved.

  In particular, since the integrated terminal main body 8, 9, 10 having both terminals (contact points) can be easily fitted into the mounting groove 12 of the support 11, the delicate terminal main body 8, 9, 10 can be assembled. This makes it possible to facilitate the production of the conversion connector 4.
