Abstract

A connector provided on a projector has an RF chip. A plug connected to the connector has an RF chip at a position opposite to the RF chip of the connector. When a protruding section of the plug is inserted and fit into an aperture section of the connector, the RF chip of the plug and the RF chip of the connector perform wireless communication with each other in a non-contact state. Thus, a connecting tool can be easily attached to/detached from a receiving tool without breaking a terminal due to contact such as in a case where a conventional contact type terminal is used.

Claims

1. A connector system comprising:

a receiving tool provided on a device; and

a connecting tool connected to the receiving tool in a freely attachable/detachable manner to establish a connection between devices,

the receiving tool having a first wireless communication section that performs wireless communication,

the connecting tool having a second wireless communication section that wirelessly communicates with the first wireless communication section at a position opposite to the first wireless communication section of the receiving tool.

2. The connector system according to claim 2, wherein

the second wireless communication section of the connecting tool comprises an electric-optical conversion section for converting an electric signal received from the first wireless communication section of the receiving tool into an optical signal.

5. The connector system according to claim 2, wherein

the receiving tool comprises a power supply section for supplying power to the second wireless communication section.

8. The connector system according to claim 2, wherein a surface where the first and second wireless communication sections face each other is sealed.

9. The connector system according to claim 2, wherein

the connecting tool is inserted and fit into the receiving tool in a given direction, and

the first and second wireless communication sections are positioned so that the given insertion direction is orthogonal to the direction normal to the output surface of a wireless signal emitted by the first and second wireless communication sections.

3. The connector system according to claim 3, wherein

the connecting tool comprises an optical transmission path transmitting the optical signal converted by the electric-optical conversion section.

4. The connector system according to claim 4, wherein

the second wireless communication section comprises an optical-electric conversion section for receiving an optical signal that propagates through the optical transmission path connected to the second wireless commutation section, and for converting the optical signal into an electric signal.

6. The connector system according to claim 6, wherein

the first and second wireless communication sections have a plurality of transmitting antennas and receiving antennas, and

when a plurality of the transmitting antenna and receiving antenna combinations are positioned, the power source supply section restricts power supply to the transmitting antennas and receiving antennas in order to prevent interference.

7. The connector system according to claim 7, wherein

when the plurality of the transmitting antenna and the receiving antenna combinations are positioned, the transmitting antennas and receiving antennas are positioned by changing the plane of polarization of the transmitting antennas adjacent to each other and the receiving antennas adjacent to each other in order to prevent interference.

10. A connecting cable comprising:

a cable for transmitting a signal;

a first connecting tool attached to one end of the cable; and

a second connecting tool attached to the other end of the cable;

at least one of first and second connecting tools being connected in a freely attachable/detachable manner to a receiving tool of a device provided with the receiving tool having a first wireless communication section that performs wireless communication, and having at a position opposite to the first wireless communication section of the receiving tool a second wireless communication section that performs wireless communication with the first wireless communication section.

11. A receiving tool connecting in a freely attachable/detachable manner to a connecting tool having a second wireless communication section that performs wireless communication, and having at a position opposite to the second wireless communication section of the connecting tool a first wireless communication section that performs wireless communication with the second wireless communication section.
