A first connector housing formed of a conductive resin is disposed with a first optical device accommodating part for accommodating a light receiving device. A second connector housing formed of a non-conductive resin is disposed with a second optical device accommodating part for accommodating a light emitting device and electric terminals. The coupling end faces of optical fibers are fixed to a plug connector and the plug connector is inserted into a plug connector fitting part. This insertion allows optical coupling of the optical fibers to the light emitting device and the light receiving device, and it allows electrical coupling of the above electric terminals to wires fixed to the plug connector. The first and second optical device accommodating parts are arranged so that their positions are displaced in the longitudinal direction of the optical fibers, whereby the electrical crosstalk between the light receiving device and the light emitting device is suppressed.
two or more optical device accommodating parts for accommodating optical devices; and an optical connector housing provided with an insertion part configured to receive a plug comprising two or more optical fibers and to couple the two or more optical fibers to the two or more optical devices, wherein among optical device accommodating parts, each accommodating part having a positions displaced relative to each adjacent accommodating part such that each of the optical device accommodating parts in non-overlapping with each adjacent accommodating part in the longitudinal direction of the optical fibers inserted into the insertion parts for optical fibers. 2. The connector according to claim 1,
wherein the connector housing is provided with electric terminals, a first optical device accommodating part is disposed at a first position, and a second optical device accommodating part adjacent to the first optical device accommodating part is disposed at a second position, wherein the second position is more forward than the first position of the first optical device accommodating part. 3. The connector according to claim 2,
wherein the connector housing has at least a first connector housing having the first optical device accommodating part and a second connector housing disposed with the electric terminals, and the first connector housing is formed of a conductive resin and the second connector housing is formed of a non-conductive resin. 4. The connector according to claim 2,
wherein a light receiving device is accommodated in the first optical device accommodating part, and a light emitting device is accommodated in the second optical device accommodating part. 5. The connector according to claim 4,
wherein an optical coupling intermediated optical fiber for mediating coupling of an optical fiber inserted into the connector housing to the light receiving side of the light receiving device, and a lens causing light emitted from a light emitting device to enter an optical fiber inserted into the connector housing on the light emitting side of the light emitting device. 6. The connector according to claim 5,
wherein the light emitting device has an incident numerical aperture greater than the optical fiber inserted into the connector housing, and the lens is formed to be a condensing lens for condensing light emitted from the light emitting device so as to allow the light to have an incident numerical aperture smaller than a numerical aperture of the optical fiber and thus causing the light to enter the optical fiber. 7. The connector according to claim 4, wherein the light receiving device is a photodiode (PD), and the light emitting device is a light emitting diode (LED).
FIELD OF THE INVENTION The present invention relates to a connector such as a hybrid optical/electrical connector or optical connector mounted and disposed in a vehicle for use in optical communications inside the vehicle.
BACKGROUND OF THE INVENTION Recently, the computerization of vehicles has been advanced dramatically. For example, it is performed that the location of a vehicle is denoted on a map by using car navigation systems. Additionally, by utilizing the ITS (intelligent transport systems), the management of solving traffic congestion of vehicles is conducted. With such computerization, the throughput of communication information such as data, image and voice inside a vehicle has been increasing.
SUMMARY OF THE INVENTION The connector of the invention comprises:
DETAILED DESCRIPTION Devices performing the optical communications for vehicles are mounted with electric connectors for power supply or electric connectors for telecommunications adapted to low bit-rate information transmission, for example. Therefore, the work to fit these electric connectors to the optical connectors is needed. In order to eliminate the need for this work, the application of a hybrid optical/electric connector having both functions of the optical connector and the electric connector can be considered.
The first and second optical device accommodating parts 41 and 42 are arranged side by side with their positions displaced relative to each other in the longitudinal direction of the optical fibers 12 and 13. However, according to the configuration of the hole parts 35 and 36, the coupling face of the light emitting device 10 to the optical fiber 12 and the coupling face of the light receiving device 11 to the optical fiber 13 are in the same plane as indicated by a line S�S shown in FIG. 2B.
That is, in the hybrid optical/electric connector 1 of the embodiment, the effective area of a substrate (circuit bard) to mount the hybrid optical/electric connector 1 thereon can be expanded by an area of C times B (10.3 mm�8.2 mm) as compared with the case where the first optical device accommodating part 41 and the second optical device accommodating part 42 are arranged side by side at the same positions in the Z-direction, for example. Accordingly, the hybrid optical/electric connector 1 of the embodiment can utilize the substrate space effectively.
