- the communication connector 7 to be further connected at this time is connected to the communication line 702 through the internal transceiver 72 and the connection unit 73, and an expansion connector 81 having an expansion plug 82 is connected to the communication line 702. .
- the expansion of the system is realized by connecting the plug 82 of the expansion connector 81 to the connection portion 73 of the end communication connector 7 in the system corresponding to the standard equipment.
- the extension connector 81 sends a communication signal of the communication line 700 branched and output from the connection unit 73 connected via the plug 82 to the communication line 702. At this time, the extension connector 81 can be connected to the communication connector 7 as long as the plug 82 is inserted into the communication connector 7 as shown in FIG.
- the communication connector 7 connected via the communication line 702 is connected to the system. Further, it is realized by connecting the communication connector 1.
- the communication connector 1 in a form that does not have the expansion connection portion shown in the first embodiment may be used.
- the communication connector 1 is connected to the communication connector 7 to which the communication line 702 is connected.
- the communication connector 1 constituting the in-vehicle communication system 9 is connected to an expansion connector 81 having an expansion plug 82 via a communication line 703.
- the plug 82 of the expansion connector 81 By connecting the plug 82 of the expansion connector 81 to the connection portion 73 of the communication connector 7 to which the communication line 702 is connected, further expansion of the system is realized, and the in-vehicle communication system 9 shown in FIG. 6 is constructed. .
- the extension connector 81 connected to the communication connector 1 further branches the communication signal of the communication line 702 branched and output from the connection unit 73 connected via the plug 82 and sends it to the communication line 703.
- the communication connector 1 (or 5, 7) realizes processing based on the communication protocol. Therefore, the ECU 2 is a system that employs any communication protocol. A common configuration can be used without depending on the protocol. The ECU 2 can be realized with an inexpensive configuration because it is not necessary to prepare a microcomputer corresponding to a network controller conforming to various communication protocols.
- connection portion 10 (or 50, 70, 73) in the communication connector 1 (or 5, 7) is fitted to the signal line provided inside to contact the signal input.
- the configuration is not limited to output. Even though the connection unit 10 and the input / output unit 20 are configured to physically fit, the signal lines provided therein are configured to be input / output (communication) by contactless wireless transfer without contact. Also good.

Abstract
Description
なお、以下に示す実施の形態では、本発明に係る通信コネクタを車載通信システムに用いる場合を例に挙げて説明する。
図1は、実施の形態1における通信コネクタを含む車載通信システム102の構成を模式的に示す構成図であり、図2は、実施の形態1における車載通信システム102を構成する通信コネクタ及びECUの内部構成を示すブロック図である。図中1が通信コネクタであり、プラグからなる接続部10を有し、2に示すECUの入出力部20が設けられたレセプタクルと嵌合するように接続される。通信コネクタ1は、図中100に示す通信線に複数接続されており、通信ハーネス101を構成する。
実施の形態2では、通信システムを拡張するGWの機能を内蔵したコネクタを更に備える車載通信システムの例を説明する。図3は、実施の形態2における車載通信システム104の構成を示すブロック図である。なお、実施の形態2における車載通信システム104の構成の内、実施の形態1と共通する構成については同一の符号を付して詳細な説明を省略する。
実施の形態2では、通信コネクタ1はGWコネクタ3を挟むようにしてECU2に接続される構成とした。このとき中継機能は必須ではなく、通信線100の通信信号を分岐させるバスバーのみでもよい。図4は、実施の形態3における車載通信システム105の構成を示すブロック図である。実施の形態3における車載通信システム105の構成の内、実施の形態1又は2と共通する構成については同一の符号を付して詳細な説明を省略する。
図5は、実施の形態4における車載通信システムの構成を示すブロック図である。実施の形態3における車載通信システム105の構成の内、実施の形態1又は2と共通する構成については同一の符号を付して詳細な説明を省略する。
