Description

TECHNICAL FIELD [0001] The present invention relates to a connector for a photoelectric composite cable, and a photoelectric composite cable cable including the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for a photoelectric composite cable and a photoelectric composite cable cord. More particularly, the present invention can cope with a simple structure, simple assembly, And a photoelectric composite cable cable and a photoelectric composite cable cable for minimizing the cost.

In the conventional mobile communication, a communication signal is transmitted from the base station to a base station, and an RF signal transmitted from a base transceiver station (BTS) of the base station is wirelessly transmitted through a base station antenna. Also, a radio signal transmitted from a user's portable terminal is received by the base station antenna, and the received signal is amplified through a TMA (Tower Mount Amplifier) and transmitted to the BTS.

At this time, the BTS, the TMA, and the antenna of the base station are connected to the coaxial feeder line, but the signal loss is large as the length of the coaxial feeder cable increases. When the antenna is installed in a tower having a height of several tens of meters, a loss increases in a coaxial feeder line connecting a base station on the ground and the antenna, and a signal provided by the base station due to signal loss of the coaxial feeder is required To attenuate the signal without reaching the intensity of the signal, a Tower Mounted Amplifier (TMA) is installed to compensate and amplify the signal.

However, since the TMA consumes a relatively large amount of power in order to amplify the signal, the TMA requires a large amount of maintenance in terms of the overall system, which leads to a problem of inefficiency.

Meanwhile, base station facilities are evolving as the evolution of FTTx (Fiber to the X) and the miniaturization of repeaters. Among these, the optical unit is characterized by a very small signal attenuation according to the cable length as compared with the coaxial cable. RRH (Remote Radio Head), which is a technology to convert optical signals into RF signals capable of emitting optical signals immediately before the antenna, has been introduced.

The remote radio head (RRH) is a complement to the inefficient disadvantages of power consumption and maintenance of a mobile communication base station using a conventional TMA. The RRH separates the RRU (Remote RF Unit) from the conventional BTS and places it remotely underneath the antenna of the base station tower.

The remaining parts of the existing BTS in which the RRU is separated in the RRH, that is, the BBU (Baseband Unit) and the PSU (Power Supply Unit) are connected to the RRU by a photoelectric hybrid cable including an optical unit and a power unit with little attenuation per length , A communication signal from a Baseband Unit (BBU) and a Power Supply Unit (PSU) is supplied to an RRU (Remote RF Unit) through an optical unit constituting the photoelectric hybrid cable, and the electric power is supplied to the RRU (Remote RF Unit).

Since the RRU (Remote RF Unit) can be installed just below the base station antenna at the top of the base station Tower, the length of the coaxial feeder for supplying the RF signal converted by the RRU (Remote RF Unit) to the antenna is minimized, Since the attenuation of the RF signal generated when the RF signal is transmitted through the line does not matter, the attenuation amount of the signal up to just before the radiation is minimized, and the necessity of the TMA using the conventional power consumption is eliminated. This technical feature has become a feature of the RRH in terms of the maintenance of the base station.

In this RRH system, BBU (Baseband Unit), PSU (Power Supply Unit) and RRU (Remote RF Unit) are connected via a terminal box for photoelectric hybrid cable.

That is, the photoelectric hybrid cable connected to the base station is provided with a plurality of optical units and power units as a single cable, so that a BBU (Baseband Unit), a PSU (Power Supply Unit) and a plurality of RRU It can not be directly connected to the cable, but a method of connecting a plurality of RRUs and a terminal box using a separate jumper cable in a terminal box for a photoelectric hybrid cable can be used.

The connection operation between the RRU and the terminal box can be performed by installing a terminal box first under the base station antenna and then connecting a jumper cable to each terminal box.

The jumper cable connecting the RRU and the terminal box is preferably configured such that the end of the jumper cable is respectively connected to the connector so that the operator can easily work in the field since the connection operation must be performed in the field after the terminal box is installed.

Recently, various types of portable terminals have been diversified, and new and old terminals having different communication methods have been coexisted with each other in communication companies or communication generations, and RRUs, antennas and the like have been diversified. That is, as the capacity, performance, or coverage of the antenna is changed, the required power of each RRU can be diversified.

As a result, the diameter of each jumper cable will be determined according to the required power of the RRU or antenna, and the diameter of the jumper cable connected to one terminal box may vary.

A connector socket provided in a terminal box or the like and a connector provided in a jumper cable need to be standardized even if the diameter of the jumper cable connecting the RRU and the terminal box is varied in the base station or the like.

In summary, when a connector of a jumper cable as a photoelectric composite cable is connected to a terminal box of a base station and an RRU, a connector capable of coping with various cable diameters is required. However, a method of designing a metal- It is not preferable.

The present invention provides a connector for a photoelectric composite cable and a photoelectric composite cable cord which are simple in structure and simple to assemble, can cope with a change in the diameter of the cable by a method replacing a part of the structure, and can minimize weight and cost This is a problem to be solved.
