[0002]

2. Description of the Related Art IEEE 1394 is a serial bus standard for data transmission created by the International Association of Electrical and Electronics Engineers (IEEE) for use in audio and / or video equipment. Or, it is an interface technology for connecting home appliances through a single network so that multimedia data can be exchanged at a high speed of about 100 Mbps to 3200 Mbps.

The IEEE 1394 supports hot-plugging for connecting and disconnecting peripheral devices in a system without interrupting power supply, and connects and uses devices in series, so that up to 63 devices can be connected. 4.5m between
Within. Currently, IEEE1 is the standard draft of IEEE1394.
394-1995 and IEEE 1394a. IEEE13
94-1995 is an interface system composed of a total of six lines of four lines for signal and two lines for power supply. IEEE1
394a is a standard proposal for a case where audio and / or video equipment having a DC power supply is equally connected to exchange data or to be connected to a host without any need to be supplied with power from the host. This is an interface system composed of four lines.

[0004] FIG. 1 shows an example of a home network configuration diagram using the above-mentioned IEEE 1394 in the construction of a home network that is currently being commercialized. Referring to the drawings, the home network is an electric appliance, for example, a digital video camera 5a, a digital VTR 5
b, scanner 5c and digital camera 5d, personal computer 1a,
By configuring the printer 1b and the printers 3a and 3b by using the IEEE1394-dedicated cable 7 and the IEEE1394 connector 9, it is possible not only to recognize each device through an electric signal but also to exchange data. Here, the IEEE 139
4 connector 9 includes a plug (not shown) attached to both ends of the cable 7 and an IEEE1394 connector socket (not shown) detachably attached to the plug and attached to each device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG.
FIG. 3 is a perspective view showing an appearance of a connector socket structure 10 according to a preferred embodiment of the present invention, and FIG. 3 is a front view of FIG.

Referring to the drawings, a housing 20 has a form in which a front portion 20a is opened. The housing 20
A fixing pin 22 for fixing the connector socket structure 10 to a printed circuit board of a corresponding device protrudes from the outside. The inside of the housing 20 projects from the rear bottom surface toward the front 20a side.
, A pin installation part 30 which is separated from the upper, lower, left and right side walls. The pin installation section 30 is provided with six pins 32 for electrical signal connection in a 2 × 3 matrix arrangement.

As described above, since the pin mounting portion 30 is separated from the side wall of the housing 20, the pin mounting portion 3
A space S is formed between the housing 0 and the side wall of the housing 20. FIGS. 2 and 3 show an IEEE 139 composed of six lines.
This figure shows the case of the connector socket structure 10 having the standards of the four standard proposals, and the number of such pins 32 is four.
In the case of the IEEE 1394 standard proposed by a line, the number is four, and if another standard is adopted, it may change correspondingly.

According to the present embodiment, the pin mounting portion 30
The optical element modules 40 and 50 are provided in a space S between the housing and the side wall of the housing 20. Preferably, the optical element modules 40 and 50 include the pin installation part 30 and the left side wall 20.
b, each is provided in a space S between the pin installation part 30 and the right side wall 20c. The optical device modules 40 and 50 are at least one light emitting device module 40 and / or at least one light receiving device module 50. here,
The number and arrangement of the optical device modules 40 and 50 may be variously modified.

The light emitting element module 40 converts an electric signal from a device (not shown) provided with the connector socket structure 10 according to the present invention into an optical signal and outputs it.
The light receiving element module 50 receives an optical signal, converts it into an electric signal, and inputs the electric signal to the device side. The connector socket structure 10 according to the present invention as described above conforms to the IEEE 139 standard.
The connection structure between the 4 connector socket, its external form and the IEEE 1394 plug (not shown) connected thereto is substantially the same, and the light emitting element and light receiving element required for communication using an optical fiber are small. Since it is manufactured in the form of a module and is built in the socket 10, not only electric signals but also optical signals can be transmitted.

Only electrical signals are transmitted to the connector socket structure 10 according to the present invention as described above.
If an IEEE 1394 plug (not shown) is connected, this plug is connected to the pin 32 and transmits only electrical signals. And the external form and the structure for fastening are
An optical cable (not shown), which is almost the same as the IEEE 1394 plug, is provided with an optical cable dedicated plug (not shown) corresponding completely to the connector socket structure 10 according to the present invention.
, The input and output ends of the optical cable face the light emitting element and light receiving element modules 40 and 50 to transmit an optical signal. On the other hand, when a plug (not shown) that simultaneously mounts an optical cable adapted to transmit at least one channel optical signal to a wire cable suitable for the IEEE 1394 standard is connected to the connector socket structure 10, Signals and optical signals can be transmitted simultaneously.

Therefore, a user who has already configured a home network with an IEEE 1394 connector and an electric wire cable requires a user who needs high-speed data transmission, such as a computer (1a in FIG. 1) and a digital video camera (1 in FIG. 1). 5a) is additionally provided with the connector socket structure 10 according to the present invention, or the connector socket structure 1 according to the present invention is provided.
0 can be easily connected to an optical signal transmission system by connecting a device equipped with a 0 to a network.

For a network configuration, one device is usually provided with a pair of connector sockets. Therefore, for example, in a computer 1a equipped with a pair of connector socket structures 10 according to the present invention, a device that requires high-speed signal transmission and reception by connecting a plug equipped with an optical cable to one connector socket, such as a digital video camera 5a Send and receive data at high speed using light between
The other connector socket is connected with a plug for IEEE 1394 on which an electric cable is mounted, for example, a printer.
(3b in FIG. 1) allows data to be transmitted at a normal IEEE 1394 transmission rate.

[0016]

Therefore, the connector socket structure according to the present invention as described above incorporates an optical module while maintaining the standard of the IEEE1394 connector, so that an electric signal and an optical signal can be selected as required. Can be processed. Therefore, an effective and economical home network can be created. In addition, if the connector socket structure according to the present invention is adopted, for example, in a short distance of less than 4.5 m, IEEE1
The use of an 394 electric cable and the use of an optical cable whose transmission distance is longer than that of the electric cable in a longer distance than that of the electric cable allows the distance between the devices constituting the home network to be more actively arranged. .
