Description

CONNECTOR FOR COMMUNICATION [0002]

The present invention relates to a communication connector, and more particularly, to a communication connector capable of stably connecting communication cables to a PC and at the same time effectively reducing a volume due to a connector in a PC itself.

Currently, industrial Ethernet such as PROFINET, EtherCAT, and Ethernet IP is increasingly used in the field of factory facility automation including inverters for motor drives.

Conventional Industrial Ethernet is the same as physically common Ethernet, so it is easy to use and has a very good speed and reliability compared to the communication method used before.

In addition, in the conventional industrial Ethernet, a ring topology or a daisy chain topology can be used to increase reliability or facilitate connection by using two ports in one terminal.

However, the use of two ports increases the area of the connector in the PC.

In addition, the two ports are arranged in parallel to each other, causing physical problems such as forcibly breaking the Ethernet cable when connecting to the cable.

FIG. 1 is a schematic view showing a connection state of a conventional Ethernet cable, FIG. 2 is a view showing a state where the Ethernet cable of FIG. 1 is bent, and FIG. 3 is a view showing a connection state of the Ethernet cable with two ports.

Referring to FIG. 1, in the inverter for the motor drive, in the case of the industrial Ethernet communication option, the PC 10, which is a communication option, is mounted inside the inverter 10.

The PC 20 is provided with an Ethernet communication processing unit 21 and two ports 30 arranged side by side on one side of the PC 20.

The two ports 30 are electrically connected to the Ethernet communication processing unit 21.

Each port 30 forms eight communication lines 31 and is connected to the Ethernet communication unit 21.

Each of the ports 30 is connected to the Ethernet cable 40 separately.

Each Ethernet cable 40 includes eight wires connected to each port 30.

The Ethernet cable 40 may take the form of a "ring topology" or a "daisy chain" in the field.

In particular, the PC used as an industrial Ethernet communication option is limited by space.

In the case of an inverter for a motor drive, it is possible to provide more services to the user if a plurality of options can be installed, but the size of the PLC is limited.

In addition, the conventional two ports 30 are disposed side by side in the structure of the PCB 20.

In this structure, when each Ethernet cable 40 is connected to the corresponding port 30, it is necessary to connect the corresponding Ethernet cable 40 to the corresponding port 30 by bending to 90 degrees as shown in FIGS. 1 and 2 Often occurs.

Accordingly, conventionally, there is a problem that the wires included in the cable 40 are disconnected or communication failure occurs due to the bending of the Ethernet cables 40 close to 90 degrees.

In addition, as shown in FIG. 3, when the width W between the wires in the Ethernet cable 40 in the bent portion is tangent to each other, there is a problem that a communication failure occurs.

A prior art related to the present invention is Korean Public Release No. 10-2006-0086737 (Publication Date: 2006.08.01), which discloses a connector for a mobile communication terminal.

It is an object of the present invention to provide a communication connector capable of stably connecting communication cables to a PC and reducing the volume due to connectors in the PC itself.

In a preferred embodiment, the present invention provides a connector for communication.

The communication connector includes: a connector body portion; A connector formed at one side of the connector body; A pair of connection port portions formed on both sides of the connection portion corresponding to each other; And a communication line unit for electrically connecting the connection unit and the pair of connection port units.

Preferably, a plurality of second connection contacts are formed in each of the pair of connection ports.

Preferably, a plurality of first connection contacts are formed in the connection portion.

The number of the plurality of first connection contacts may be two times the number of the plurality of second connection contacts of any one of the pair of connection ports.

The number of the first connection contacts may be sixteen, and the number of the second connection contacts of each of the pair of connection ports may be eight.

And the connection portion and the pair of connection ports are formed in the connector body portion so as to be orthogonal to each other.

The connection portion and the pair of connection port portions may be provided as one module.

It is preferable that a plurality of modules are provided in the connector body portion.

In another embodiment, the present invention provides a communication device including the communication connector described above.

The present invention has the effect that the communication cables can be stably connected to the PC and the volume due to the connectors in the PC itself can be efficiently reduced.

In addition, the present invention does not require two ports in the PC, and when each Ethernet cable is connected to the corresponding port, the cable is bent to reach 90 degrees and connected to the corresponding port, The problem of the amount of water can be easily solved.

The present invention has the effect of effectively solving the problem of space limitation by having two ports in the communication equipment because it does not have two ports in one PC ratio as in the prior art.
