Abstract

PURPOSE:To reduce the sorts of cable and to make it possible to change the number of appliances to connect easily by cutting off a connection cable on the middle way and connecting the cutting part with a repeater. CONSTITUTION:A cable repeater 2 has an input connector 2a and an output connector 2b. The input connector and the output connector of each cable repeater are connected with their pins one to one, and a signal input to the input connector is to be output as it is to the responding pin of the output connector. Accordingly, one side of the connecting cable from each communication appliance is connected to the input connector of the cable repeater for the neighboring communication appliance, and the other side is connected to the output connector of a cable repeater responding to the own communication appliance. Consequently, for the cable to connect communication appliances, only one sort of cable from a communication appliance to a cable repeater may be prepared, to respond easily to the number of communication appliances which is increased or decreased.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、複数の機器を接続ケーブルによって接続す
る機器間接続装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inter-device connection device that connects a plurality of devices using a connection cable.

〔従来の技術〕[Conventional technology]

一般に、複数の機器を接続して一つのシステムを構成す
るとき、それらの装置間は接続の容易さからコネクタ付
きケーブルによって接続することが多い。Generally, when a plurality of devices are connected to form one system, these devices are often connected by cables with connectors for ease of connection.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

しかしながら、接続すべき装置の数が多くなりしかも、
それらをデージ−チェーン接続するシステムであって、
装置の数が増減するとき、ケーブルは装置の数に適合し

有してていた。However, the number of devices to be connected increases, and
A system for connecting them in a daisy chain,
When the number of devices increases or decreases, cables must be adapted to the number of devices, and as the number of systems increases, it is necessary to prepare many types of cables, which complicates production management and maintenance. Furthermore, there is a problem in that it is difficult to cope with increasing or decreasing the number of communication devices within one system.

〔問題点を解決するための手段〕[Means for solving problems]

このような問題を解決するためにこの発明は、機器間を
接続する接続ケーブルを途中で切断し、そこを中継器に
よって接続するようにしたものである。In order to solve this problem, the present invention is such that a connection cable that connects devices is cut in the middle, and the cables are connected by a repeater.

〔作用〕[Effect]

ネクタの同一ピンから出力されるようになっている。す
なわち、電気的には中継器を通さない場合と同一の作用
をするようになっている。A cable can be shared between the communication equipment and the disconnection point (Embodiment) FIG. 1 is a connection diagram showing an embodiment of the present invention. In the figure, l is a communication device, 2 is a cable repeater provided in the housing of the communication device, 3 is a connection cable, and the cable repeater 2 is an input connector 2a and an output connector 2b.
has. In each cable repeater, the input connector and output connector are connected in a 1-to-1 ratio, so that the signal input to the input connector is directly output from the same pin of the output connector. It has become. That is, electrically, the same effect as when no repeater is used is achieved.

このように構成された装置は、各通信装置から出た接続
ケーブルの一方は隣接する通信装置用のケーブル中継器
の入力用コネクタに接続され、接続ケーブルの他方は自
分の通信装置に対応するケーブル中継器の出力用コネク
タに接続される。In a device configured in this way, one of the connection cables coming out of each communication device is connected to the input connector of the cable repeater for the adjacent communication device, and the other side of the connection cable is connected to the cable corresponding to the own communication device. Connected to the output connector of the repeater.

このようにすると、通信装置間を接続するケーブルは通

座に対応でき、いままで使用していたものには何等影響
を与えない。In this way, by preparing only one type of cable for connecting communication devices from the communication device to the cable repeater, it is possible to easily cope with an increase or decrease in the number of communication devices. In other words, when the number of communication devices increases, it can be handled by increasing the number of connection cables and connecting them via cable repeaters.
When the number of communication devices decreases, it can be dealt with immediately by simply disconnecting the connection cable, and the devices that have been used up until now are not affected in any way.

信装置間で行われてれている通信を停止しなければ、故
障した通信装置を取り外すことはできない。このため、
修理は現地で行わねばならない。By the way, with such a configuration, for example, if a certain communication device breaks down and you try to remove it from the system for maintenance and repair it, the cable repeater is attached to the case of the communication device, so it will not be possible to repair the other communication device. A failed communication device cannot be removed without stopping the communication between the communication devices. For this reason,
Repairs must be carried out on site.

この問題を解決したものが第２図の例であり、ケーブル

By doing this, even if any communication device is removed, the other communication devices can continue to communicate without any problems, so it is possible to carry the malfunctioning communication device to a maintenance center for repair. becomes possible.

行えるようになるという効果を有する。As explained above, in this invention, the connection cable that connects devices is cut in the middle, and then connected using a cable repeater for cable connection, so the types of cables used can be reduced. It also has the effect of making it easier to increase or decrease the number of devices.
