  The melted reflow solder 71 gathers around the central portion, that is, the legs 64 and 65 due to surface tension. Then, the reflow solder 71 is pushed out to the lower surface side of the printed circuit board 5 by the pressure, and as shown in FIG. 27, a fillet-shaped drop prevention section 72 in which the outer peripheral portion is applied to the land section 68 on the lower surface side of the printed circuit board 5. Is formed, and the cradle side connector 3 is firmly attached integrally to the printed circuit board 5. In order to fill the reflow solder 71 in the leg insertion holes 66 and 67 and to form the drop prevention portion 72 on the lower surface side of the printed circuit board 5, the thickness of the reflow solder 71 to be applied, the leg insertion hole 66 , 67 and the clearance between the outer surfaces of the legs 64, 65 are taken into consideration.

(4) Configuration of Device-side Connector As shown in FIGS. 28 and 29, the device-side connector 121 includes an insertion port 122 for inserting the cradle-side connector 3 on one end side, and a pair of arm portions 123 on the other end side. , 123 and a metal cover 125 attached to the outer peripheral side of the connector main body 124.

  The cover 125 is formed in a substantially square cylindrical shape, and a plurality of tongue pieces 126 for preventing removal are cut and raised on one side surface.

  When the connector main body 124 is inserted into the cover 125, the plurality of removal preventing tongues 126 are engaged with tongue engaging portions (not shown) provided on the connector main body 124, and the cover 125 is prevented from dropping from the connector main body 124.

  The device-side connector 121 is connected to a printed circuit board 131 superimposed on a side surface opposite to the side surface on which the plurality of removal prevention tongue pieces 126 are provided.

  The device-side connector 121 is integrally attached to the printed circuit board 131 by soldering a pair of soldering tongues 127 formed by cutting and raising the cover 125. Then, as shown in FIG. 29, one end of the terminal (contact) 128 of the device-side connector 121 contacts a terminal contact portion (contact contact portion) 129 provided on the printed circuit board 131.

  As shown in FIG. 30, a notch 132 for exposing the side surface 125 a of the cover 125 is formed at the lower end of the printed board 131.

  The bottom plate 108 is molded by a synthetic resin. The bottom plate 108 includes a substantially rectangular cylindrical connector insertion portion 141 into which the device-side connector 121 is inserted on the inner surface side. The connector insertion portion 141 has a pair of printed circuit board receiving holes 142 on opposite side surfaces. When the device-side connector 121 is inserted, both side portions 131a and 131b of the printed circuit board 131 are inserted as shown in FIG. Protrudes from the pair of printed board receiving holes 142 to the outside of the connector insertion portion 141.

  The connector insertion portion 141 includes a pair of connector side pressing ribs 143 on the inner surface. The connector holding rib 143 enters the notch 132 provided in the printed circuit board 131 when the device-side connector 121 is inserted into the connector insertion portion 141, directly presses the side surface 125a of the cover 125, and The device-side connector 121 is pressed against the surface of the connector insertion portion 141 that faces the surface on which the connector pressing rib 143 is provided, and is positioned in a direction orthogonal to the insertion direction of the device-side connector 121 into the connector insertion portion 141. .

  In addition, when the device-side connector 121 is inserted to a predetermined position of the connector insertion portion 141, the pair of arm portions 123 and 123 abut on the upper end of the connector insertion portion 141, and positioning in the insertion direction is performed. The

  After the device-side connector 121 is inserted into the connector insertion portion 141, as shown in FIG. 32, the device-side connector 121 is inserted into the connector by pressing the upper surface of the device-side connector 121 with the connector upper surface pressing member 144. This prevents the portion 141 from coming out.

  The connector upper surface holding member 144 includes a screw receiving portion 145 on one end side and a base plate portion 147 on the other end side via a connecting portion 146. The screw receiving portion 145 of the connector upper surface pressing member 144 is screwed to the screw screwing portion 151 of the printed circuit board 131 with a screw (not shown). The base plate portion 147 is screwed to the bottom plate 108 with screws (not shown). The base plate portion 147 includes a hole 148 for inserting a guide pin receiving portion 111 provided on the bottom plate 108 and a cap portion 149 that closes an upper portion of the screw portion 112 for a tripod.

(5) Operation The cradle 1 and the imaging device 101 according to the embodiment have the above-described configuration, and an attachment error of the cradle side connector 3 to the cradle cabinet 2 or an attachment error of the device side connector 121 to the imaging device 101. Even when there is a slight position between the cradle side connector 3 and the device side connector 121 due to the above, etc., if the error is within an allowable range, the cradle side connector 3 is fitted to the device side connector 121. Further, the cradle side connector 3 is displaced (moved) together with the printed circuit board 5 within the range of the play gap G1, and the device side connector 121 and the cradle side connector 3 are securely fitted.

  In the cradle 1 of the present invention, the upper and lower surfaces of the printed circuit board 5 are formed by the printed circuit board sandwiching ribs 24 and 25 provided in the upper cabinet 21 constituting the cradle cabinet 2 and the printed circuit board sandwiching ribs 32 and 33 provided in the lower cabinet 22. Since the cradle side connector 3 is displaced by being clamped and positioned, the printed circuit board 5 must be displaced (moved) against the clamping force, and the cradle side connector 3 is moved by a conventional floating mechanism. Compared with the case of displacing only the cradle side connector 3, a strong force is required for fitting the cradle side connector 3 to the device side connector 121. However, once the displacement is made, the printed circuit board 5 is held in that position by the clamping force. From the second time on, the cradle-side connector 3 fits smoothly into the device-side connector 121.

As described above, when the cradle-side connector 3 is first fitted to the device-side connector 121, a stronger force acts on the cradle-side connector 3 than that using a conventional floating mechanism. As shown in FIG.
The pair of pedestal legs 64 and 65 are inserted into the leg insertion holes 66 and 67, and the front ends are soldered to the lower surface of the printed circuit board 5 and are firmly attached to the printed circuit board 5, so that they are somewhat strong. Even if force is applied, the cradle connector 3 does not fall off the printed circuit board 5.

  Further, as shown in FIG. 30, a notch 132 is provided in a printed board 131 attached to one side of the device-side connector 121, and the device-side connector 121 is inserted into a cylindrical connector provided on the bottom plate 108 of the imaging apparatus 101. When inserted into the portion 141, the connector side pressing rib 143 provided on the inner surface of the connector insertion portion 141 comes into contact with the side surface of the device side connector 121 via the notch 132, so that the device side connector 121 is connected to the connector side. Positioning can be performed more reliably in the insertion portion 141. Further, the device-side connector 121 is prevented from coming out of the imaging apparatus 101 when the pair of arm portions 123 and 123 abut on the upper end of the connector insertion portion 141.

(6) Other Examples In the above-described embodiments, the imaging device and the cradle used for the imaging device have been described as examples of the portable electronic device. However, the portable electronic device is not limited to the imaging device, Various terminal devices, mobile phones, game machines, and the like may be used.
