Terminal box for optical fiber and power line composite cable

1. A terminal box for an optical fiber and power line composite cable including optical fiber units and power line units, the terminal box comprising:

a housing;

a cable lead-in part provided at a side of the housing and via which the optical fiber and power line composite cable is inserted into and connected to the terminal box;

a first intermediate connector provided in the housing, and configured to connect a lead-in optical fiber unit inserted into the housing and a lead-out optical fiber unit pulled out of the housing, the lead-in optical fiber unit branching off from the optical fiber and power line composite cable;

a second intermediate connector provided in the housing, and configured to connect a lead-in power line unit inserted into the housing and a lead-out power line unit pulled out of the housing, the lead-in power line unit branching off from the optical fiber and power line composite cable; and

a plurality of cable lead-out parts provided at a side of the housing, and via which a connection cable that is a combination of the lead-out optical fiber unit and the lead-out power line unit is pulled to the outside,

wherein the first intermediate connector and the second intermediate connector are provided on a base of the housing to have different heights.

2. The terminal box as claimed in claim 1 , wherein height between the first intermediate connector and the base of the housing is greater than heights of the second intermediate connector, the cable lead-in part, and the cable lead-out part.

3. The terminal box as claimed in claim 2 , wherein the cable lead-in part and the cable lead-out part are provided on the base of the housing at a substantially same height.

4. The terminal box as claimed in claim 2 , wherein the first intermediate connector comprises a mount extending from the base of the housing by a predetermined length and a plurality of input sockets and a plurality of output sockets provided on the mount, and the second intermediate connector comprises a plurality of input terminals and a plurality of output terminals provided on the base of the housing.

5. The terminal box as claimed in claim 1 , wherein the housing comprises a main body having a hexahedral shape and an upper portion of which is open and a cover configured to open or close an opening of the main body,

the lead-in optical fiber unit is inserted into the housing, passes by at least two sidewalls of the main body, and is then connected to the first intermediate connector, and

the lead-out optical fiber unit passes by at least two sidewalls of the main body from the first intermediate connector, and is then connected to the cable lead-out part.

6. The terminal box as claimed in claim 5 , wherein the cable lead-in part and the cable lead-out part are provided on a same sidewall of the main body.

7. The terminal box as claimed in claim 6 , wherein the cable lead-in part and the cable lead-out part are provided on opposite locations on the same sidewall of the main body.

8. The terminal box as claimed in claim 6 , wherein the first intermediate connector is provided more adjacent to the sidewall on which the cable lead-in part and the cable lead-out part are provided than the second intermediate connector.

9. The terminal box as claimed in claim 6 , wherein the first intermediate connector is provided between the cable lead-in part and the cable lead-out part in the main body of the housing.

10. The terminal box as claimed in claim 1 , further comprising:

a first guide provided in the housing to collect the lead-in optical fiber unit and the lead-out optical fiber unit; and

a second guide provided in the housing to collect the lead-in power line unit and the lead-out power line unit.
