[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector having a connecting portion configured to be rotatable.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, a so-called swing connector having a rotatable connecting portion has been known, and is generally configured as follows.

That is, the swing connector is rotatably connected to a stator (fixed portion) in which a stator contact (first conductive member) is arranged so as to be connectable to an external board, for example. It is composed of a rotor (rotating portion) and a rotor contact (second conductive member) arranged on the rotor so as to contact and electrically connect to the stator contact even when the rotor rotates.

It is difficult to shield the swing connector with a metal plate because it has a rotating portion, but as a swing connector having a metal shield plate, for example, one shown in FIG. 9 is known. In FIGS. 9A and 9B, FIGS. 9A and 9B show a state in which the rotor is rotated in the clockwise direction.

In FIG. 9, a stator 1 has a cylindrical shaft portion 2, and a plurality of stator contacts not shown in the drawing project downward in the drawing of the stator mold 3 and further extend inside the stator mold 3. Then, they are arranged on the outer peripheral surface of the shaft portion 2 at an equal pitch. One end of the stator contact protruding from the stator mold 3 is half-bonded and connected to, for example, a circuit board.

The rotor 4 has bearing portions 4 a (4 b) that engage with both ends of the shaft portion 2, and is rotatable with respect to the stator 1 as shown in FIGS. 9A and 9B. There is. The rotor 4 is internally provided with a plurality of rotor contacts not shown in the figure. One end of these rotor contacts abuts on a stator contact arranged on the outer peripheral surface of the shaft portion 2, and the other end of the rotor contacts of the rotor 4 It is configured to be electrically connected to an FPC (Flexible Printed Circuit Board) 5 connected from the outside.

With the above configuration, the electrical connection between the circuit board and the FPC 5 is maintained even when the rotor 4 rotates with respect to various arrival directions of the FPC 5.

The shield case 6 shown by hatching in the figure is composed of three pieces. That is, the stator shield 6a that surrounds the stator mold 3 and covers the shaft 2 and a part of the bearing 4a (4b) and the rotor 4 and surrounds the shaft 2 and the bearing 4a (4b). 9) is located between the rotor shield 6b formed so as to cover a part of FIG. 9A and the stator shield 6a and the rotor shield 6b in FIG. 9A, and is pulled out by the rotor shield 6b in conjunction with the rotation of the rotor 4. And a shaft shield 6c formed so as to cover a portion between the shaft 2 and the bearing 4a (4b) covered by the rotor shield 6b and the stator shield 6a.

[0009]

[Problems to be solved by the device]

 However, according to the above connector, the shaft 2 and a part of the bearing 4a (4b) (the upper surface shown in FIG. 9A) are not covered by the shield case, so that a clock pulse of a high frequency is particularly used. When a computer device or the like is connected, there is a problem of generating unnecessary radiation to the outside.

In addition, dust from the outside may come in to cause a contact failure between the stator contact and the rotor contact, or conversely, short-circuit adjacent contacts due to damp dust to ensure a reliable connection. May not be possible.

In view of the above points, it is an object of the present invention to provide a connector that can reliably make electrical connection and does not generate unnecessary radiation.

[0012]

[Means for Solving the Problems]

 The above problem can be solved by configuring as follows.

That is, the fixed portion provided with the first conductive member, the rotating portion rotatably connected to the fixed portion, and the first conductive member even when the rotating portion rotates. A connector provided with a second conductive member disposed in the rotating portion so as to contact with the first metal member disposed in the fixed portion so as to surround the first conductive member, and a second metal member disposed in the fixed portion. A second metal member disposed on the rotating portion so as to surround the conductive member, a first connecting portion connecting to the first metal member, and a second connecting portion connecting to the second metal member. A third metal member each having a third metal member configured to connect the first metal member and the second metal member to constantly surround the first conductive member and the second conductive member. Will be solved by

[0014]

[Action]

 According to the present invention having the above structure, the first conductive member disposed in the fixed portion is surrounded by the first metal member and electromagnetically shielded, and the second conductive member disposed in the rotating portion. Is surrounded by the second metal member and acts to be electromagnetically shielded.

Further, the third metal member connects the first metal member and the second metal member to connect the first conductive member and the second conductive member to each other regardless of the position of the rotating portion. Since it is surrounded, the contact portion between the first conductive member and the second conductive member is surrounded by the third metal member and acts so as to be electromagnetically shielded.
