(B) Connect the connector 7 of the mobile phone 1 to the cradle 1
0 connector 13. [0006] In the above-mentioned conventional portable telephone and hands-free cradle, in order to connect the telephone connector to the cradle-side connector, the parallelism and positional accuracy of each connector. is necessary. If the position of the connector 13 of the cradle 10 and the position of the connector 7 of the mobile phone 1 are shifted by Δ as shown in FIG. 8A, the connectors are staggered as shown in FIG. Become. Therefore, the mobile phone 1 and the cradle 10 are provided with a positioning mechanism using dedicated rails 8 and 14. However, it is difficult to provide a common positioning mechanism for various types of mobile phones. SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to realize a connector mechanism that can easily connect various types of portable telephones and a cradle connector that can be used for these telephones. [0008] The invention of claim 1 of the present invention is a connector mechanism in a cradle 21 for holding the mobile phone 20 and connecting the connector while holding the mobile phone 20, cradle 21 includes a holding rail 25 which holds the mobile telephone 20, the holding rail
25, a holder slide 23 to which a connector 25 is attached, a connector 24 connected to a connector 32 of the mobile phone 20 ,
Holder supporting holder slide 23 and connector 24
Become comprises a base 22, of the holder base 22
The connector 24 is inserted into the upper part with a predetermined gap.
Hole 27 is formed, and the hole 27 is formed in the upper lower surface.
A pair of bosses 26, 26 'are formed, and the boss 2
Holes 29, 2 that fit with a predetermined clearance into holes 6, 26 '
A substrate 28 on which 9 'is formed is provided.
The connector 24 is mounted.
The springs 31, 31 ′ for urging to raise the washer 3
0 to the bosses 26, 26 '
The connector 24 is supported so as to be movable up and down and forward and backward and left and right. By adopting this configuration, as shown in FIG. 4, even if the connector 24 of the cradle and the connector 32 of the portable telephone are displaced from each other, the connector 24 of the cradle is supported via a spring and Since it is movable right and left, it can be fitted through the states shown in FIGS. FIG. 1 is a view showing an embodiment of the present invention. FIG. 1A is a perspective view showing a state in which a portable telephone is about to be set in a cradle. (b) is a perspective view showing the back of the mobile phone. In the figure, 20 is a mobile phone, 21 is a cradle, 22 is a holder base of the cradle, 23 is a holder slide standing upright on the holder base and capable of sliding back and forth, and a connector 24 is attached to the holder base 22. Have been. The holder slide 23 is provided with a holding rail 25 vertically on a vertical surface facing the connector 24. The connector 24 can move up and down with respect to the holder base 22 as shown in FIG.
In addition, it is provided so as to be movable to some extent back and forth and right and left. That is, the holder base 22 is provided with two bosses 26 and 26 'on the left and right of the upper lower surface thereof, and a hole 27 through which the connector 24 can be inserted and the connector 24 can move to some extent in the front, rear, left and right directions. It is attached to the substrate 28 through the hole 27. The substrate 28 is provided with holes 29, 29 'of a size which can be fitted to the bosses 26, 26' of the holder base 22 and which can move to some extent back and forth and right and left. Further, springs 31, 31 'are inserted between the washer 30 screwed to the bosses 26, 26' and the board 28, and the springs 31 and 31 '
4 is urged upward (in the direction of arrow A). As shown in FIG. 1, a connector 32 is provided on the lower part of the portable telephone 20, and a guide rail 33 fitted on the holding rail 25 provided on the holder slide 23 is adhered on the back surface thereof with a double-sided tape or the like. ing. The bonding position of the guide rail 33 is determined by the connector 3 of the mobile phone 20.
2 is positioned so as to face the connector 24 provided on the holder base 22. Next, the operation of the present embodiment configured as described above will be described with reference to FIGS. First, the guide rail 33 of the mobile phone 20 is fitted and slid on the holding rail 25 of the holder slide 23, and the connector 32 of the mobile phone is connected to the connector 2 of the holder base 22 as shown in FIG.
Close to 4. When the telephone 20 is further lowered, if there is no displacement between the connectors 24 and 32, the connectors 24 and 32 are completely fitted to each other as shown in FIG. As shown in FIG. 3 (a), a connector 24 of the cradle 21 and a connector 32 of the portable telephone 20 are connected.
When the telephone 20 is lowered from the state where the connectors 24 and 32 shown in FIG. 4A are displaced from each other, as shown in FIG. One end of the connector 24 is pressed in the direction of arrow B, and the one end of the connector 24 is inclined downward. At the same time, it moves sideways in the direction of arrow C. Next, the other end of the connector 24 contacts the inside of the connector 32 as shown in FIG. If the mobile phone 20 is further lowered as shown in FIG. 3D and FIG. 3B, the connectors 24 and 32 can be completely fitted together. As described above, in the present embodiment, the portable telephone 2
Even if there is a relative displacement between the connector 32 of the cradle 21 and the connector 24 of the cradle 21, since the connector 24 of the cradle 21 is floatingly supported by the holder base 22, the connector 24 moves back and forth and left and right. Connector 32
Can be fitted. For this reason, the guide rail 3 of the mobile phone 20
It is not necessary to form 3 directly on the telephone body, and some errors may be allowed. Thereby, it can be generalized for various different models. Although the present embodiment has been described using a mobile phone, the present invention is not limited to a mobile phone.
