Abstract

The invention relates to the technical field of automobile special connecting lines, and in particular to a multifunctional on-board OBD port communication adapter line. The both ends of a connectingharness are fixedly connected with a DB9M communication output connector and an on-board OBDII connector respectively, a DB9 line bank, a double-row 8-gear 32-pin selector switch and OBD line banks are arranged in the DB9M communication output connector, the DB9 line bank is provided with 9 wiring holes in total, the OBD line banks are divided into two columns, each column has 8 holes, the multifunctional on-board OBD port communication adapter line provided by the invention solves the problem that an OBD port communication line has diversified wiring modes and is unlikely to connect, the original multiple connecting harnesses are integrated into one, thereby greatly improving the problem that the interface line is complicated and is confused easily, meanwhile, a plurality of interfaces are reserved in the on-board OBDII connector of the multifunctional on-board OBD port communication adapter line provided by the invention, and a custom interface is even provided to smoothly achieve line switching and free matching connections, facilitate the check of test line voltage and other signals, and to achieve a variety of connection communications.

Description

technical field [0001] The invention relates to the technical field of special connection wires for automobiles, in particular to a multi-function vehicle-mounted OBD port communication transfer wire. Background technique [0002] Due to different definitions of CAN, FlexRay, and LIN communication pins for different vehicle OBD interfaces, there are usually 4-8 different interface methods. CAN or LIN communication will use many wire harnesses, resulting in complicated interface lines, confusing and difficult to connect and communicate accurately. [0003] For this reason, it is very necessary to design a simple OBD port communication adapter line that can quickly and conveniently connect to OBD to realize vehicle communication. Contents of the invention [0004] The present invention breaks through the problems of the prior art, and designs a multifunctional vehicle-mounted OBD port communication adapter cable, which includes a DB9M communication output connector, a vehic...
