On the other hand, the mobile device 30 is, for example, a mobile phone, and a connector 32 is provided below the device case 31. A predetermined circuit member (not shown) is housed inside the case 32. In order to determine the position of the portable device 30 when the portable device 30 is inclined and supported by the receiving portion 13 of the stationary device 10, the receiving portion 13
A locking recess 31A that engages with the locking projection 13A is formed.

The connector 32 has a terminal 34 implanted in a block-shaped housing 33 made of an insulating material. In this embodiment, a cylindrical shield plate 35 is attached. As can be seen in FIG.
A large concave portion 36 for accommodating the area of the two mounting guide columns 17 of the mating connector 12 of the stationary device 10 is formed in a large size, and a terminal holding portion 37 projects like an island at an intermediate portion thereof. Deep portions formed on both sides of the terminal holding portion 37 in the concave portion 36 form a mounting guide column concave portion 38 for receiving the mounting guide column 17.

In the terminal holding portion 37, a plurality of immersion portions 39 are formed at positions corresponding to the terminals 16 of the stationary device 10, and the contact portions 34A of the terminals 34 are arranged here. The contact portion 34A forms a flat portion on the bottom surface of the immersion portion 39 at a position near one end of the terminal 34.

The other end of the terminal 34 enters the inside of the portable device and forms a connection portion 34B connected to a corresponding circuit (not shown) of the device.

The shield plate 35 is formed in a cylindrical shape along the inner peripheral wall of the concave portion 36 of the housing 33, and its opening edge 3
5A is located on the periphery of the concave portion 36.

In the housing 33 of the connector, a rotatable guide recess 40 for receiving the rotatable guide portion 21A of the rotatable guide post 21 of the stationary device 10 is formed outside the cylindrical shield plate 35. I have. When the portable device 30 is mounted on the stationary device 10, the bottom surface of the pivoted guide concave portion 40 has a circular arc-shaped surface that is adapted to the above-mentioned rotation guide portion 21 </ b> A. A surface 40A is formed, and the guided rotation surface 40A and the rotation guide portion 21A come into contact with each other, and come into sliding contact with each other as the portable device rotates to the inclined position. On the other hand, at this time, there is a gap between the top of the placement guide post 17 and the bottom surface of the recess 38 for the placement guide post, and there is no contact.

The apparatus of the present embodiment is used and operates as follows. When charging the portable device or transmitting / receiving a signal to / from the stationary device, as shown in FIG. 2, the portable device 30 is brought on the stationary device 10 and is used for the placement guide column of the concave portion 36 of the portable device 30. The recess 38 faces the corresponding mounting guide post 17 of the stationary device 10. From this state, the portable device 30 is lowered as it is, and as shown in FIG. 4, the placement guide pillar 17 is caused to enter the recess 38 for the placement guide pillar. As a result, the terminals are brought to their regular corresponding positions. In this embodiment,
The contact portions 15A of the two terminals 15, 16 of the stationary device 10,
16A is in the range of the contour of the mounting guide post 17 in the drawing, and since the contact portion 16A of the power terminal 16A projects more than the contact portion 15A of the signal terminal 15, the contact portion 1A of the two terminals is provided.
5A and 16A come into contact with the contact portion 34A of the partner terminal 34 in the order of the power supply terminal 16 and then the signal terminal 15 without contacting the shield case 35 of the portable device 30. The terminals described above come into contact with each other, and the guided rotation surface 40A of the portable device 30 is connected to the stationary device 10A.
Comes into contact with the rotation guide portion 21A. Next, the portable device 30 is rotated so as to be tilted toward the receiving portion 13 of the stationary device 10. This rotation is smoothly performed along the arc surface by sliding between the rotation guide portion 21A and the rotated guide surface 40A, which are in contact with each other in an arc surface. When rotated to the predetermined position, the locking recess 30A of the stationary device 10 engages with the locking protrusion 13A of the receiving portion 13 and the position is maintained (see FIG. 5). During the rotation, the contact portions 15A and 16A of the stationary device 10 and the contact portion 3 of the portable device 30
The contact point with 4A moves as the rotation progresses. Guide pillar 1
7 is erected so as to be inclined toward the receiving portion 13, and since the both sides of the guide pillar 17 are inclined portions 17, a large angle of rotation is possible. That is, both contact portions 15
A, 16A and 34A are subjected to so-called wiping. The terminals 15 and 16 of the stationary device 10 have their contact portions 15
The contact portions 15A and 16A are elastically deformed by the flexible portion under the own weight of the portable device 30 at A and 16A.
4 While being elastically displaced inward, the elastic force makes contact with the contact portion 34A of the stationary device 30 to perform wiping. Thus, the stationary device 10 and the mobile device 30 obtain a wiping effect at the terminal every time the mobile device 10 is placed under the smooth rotation, and charge,
Transmission and reception of signals at the signal terminals are performed.

Next, FIG. 6 shows another embodiment of the present invention. FIG. 6 is a cross-sectional view of a position corresponding to FIG. 2 of the previous embodiment, and is cross-sectional at a portion of a terminal support portion 19 that supports a contact portion of a terminal. In the figure, the same parts as those in the previous embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In FIG. 6, in the stationary device 10,
The rotation guide 19 </ b> B is formed on the upper surface of the terminal support 19. That is, in the terminal arrangement direction, the terminal support portion 1 is located between the contact portions 16A (15A) of the plurality of adjacent terminals.
9 is formed as a convex arc-shaped surface.

On the other hand, in the portable device 30, the housing 33 of the connector 32 is provided in correspondence with the rotation guide portion 19B.
A pivoted guide surface 33A having a concave arc shape is formed.

Thus, the rotation guide portion and the rotation guide surface are provided in the area of the connector without separately providing a rotation guide column as shown in FIG. Can be done.

FIG. 7 shows a modification of FIG.
In FIG. 6, the guided rotation surface of the portable device guided by the rotation guiding portion having the arcuate curved surface has a curved surface adapted to this. However, the rotated guided surface 33B is the same as that of FIG. It may be V-shaped as shown in FIG.

Further, as shown in FIG.
The concave and convex relationship between the rotation guide surface 33C and the rotation guide surface 33C may be opposite to that in the case of FIG.

Further, the rotation guide section may be formed on the mounting guide column by forming the upper surface of the mounting guide column of the stationary device into a concave or convex curved surface. In that case, the rotation guide surface of the mobile device is also located at a position corresponding to this,
It is formed as a conforming shape.

The present invention is not limited to the illustrated form,
Various changes are possible. For example, the contour shape of the mounting guide column includes an arc-shaped top portion and slope portions on both sides as shown in the figure, including the case where the mounting guide column also has a rotation guide portion. Instead, it may be a continuous curve or a plurality of bent straight lines. In any case, when the placement of the portable device on the placement device is started (when the placement guide column enters the guided recess), the rotation is smoothly performed, and when the placement ends (the position is held in the receiving portion). It is desired to determine that the posture is stable. Also, the housing of the connector of both devices, especially the stationary device, can be integrated with the device case. Further, the receiving portion may be formed as one surface of the mounting guide column without separately attaching a plate-shaped one as shown in the figure. In this case, for stable holding of the stationary device, it is better that the mounting guide column is tall.
Further, although the mounting guide column is inclined toward the receiving portion in the illustrated example, the mounting guide column does not need to be inclined and may be upright.

[0040]

As described above, the present invention enables the portable device to be guided by the placement guide column when the portable device is placed, and also enables the portable device to rotate, and the rotation to the rotation guide portion surface. , So that even if the number of terminals is large, positioning can be performed easily and accurately by the mounting guide columns, and the wiping effect can be surely obtained while performing smooth rotation at the time of rotation by the rotation guide portion. And the contact portions of the terminals can be cleaned.
As a result, the breadth and quality of the function of the device is improved.
