Description

Dual-channel OBD vehicle-mounted converter Technical Field The utility model belongs to the field of commercial vehicles, and particularly relates to a double-channel OBD vehicle-mounted converter. Background At present, in the commercial vehicle field, the OBDII system of whole car OBD mouth for standard possesses 16 female end joints of hole. When the whole vehicle wire harness is arranged, CAN buses of a vehicle power supply, a chassis ground, a signal ground, various electric control components and the like are connected to each pin of the OBD female end connector. Different host factories are different in definition modes of OBD pins for meeting individual requirements, and the calibration CAN of the electric control component is not provided with the OBD pins which are fixedly connected. And two OBD joints may be arranged on the whole vehicle, and the phenomenon that the whole vehicle CAN and the calibration CAN are connected to different OBD joints exists. For different host factories, the number of OBD connectors is different, and different OBD interface definitions are also different. In order to simultaneously realize all functions such as measurement calibration of the whole vehicle CAN and the calibration CAN, a plurality of conventional single-channel OBD wire harnesses or connection wire harnesses of various specifications may be required to be used simultaneously, and the wire harness operation process is complicated in the use process. Disclosure of utility model The utility model aims to provide a double-channel OBD vehicle-mounted converter, which aims to solve the problem of complicated operation during measurement and calibration in the prior art. In order to solve the technical problems, the utility model adopts the following technical scheme: A double-channel OBD vehicle-mounted converter comprises a first OBD male end plug, a second OBD male end plug, a first connecting wire harness, a connector, a first banana socket, a second banana socket, a banana plug, a second connecting wire harness, a first DB9 female end connector and a second DB9 female end connector; The first banana socket and the second banana socket are both arranged on the connector; One end of the first OBD male plug and one end of the second OBD male plug are respectively connected with two OBD female connectors of the vehicle; the stitch at the other end of the second OBD male end plug is connected with the corresponding stitch on the second banana socket through the first connecting wire harness; One end of the first DB9 female end connector and one end of the second DB9 female end connector are connected with one end of 4 banana plugs through a second connecting wire harness together, and the other ends of the 4 banana plugs are respectively connected with corresponding jacks of the first banana socket and the second banana socket; One end of the first DB9 female end connector and the other end of the second DB9 female end connector are connected with an external detection instrument. The utility model also has the following characteristics: further, 16 jacks are arranged on each of the first banana socket and the second banana socket. Further, each jack of the first banana socket and the second banana socket is marked with a serial number. Further, the first banana socket and the first OBD male plug are consistent in color; The second banana socket and the second OBD male plug are consistent in color. Compared with the prior art, the utility model has the following technical effects: (I) The dual-channel OBD vehicle-mounted converter provided by the utility model is provided with two OBD public end ports, so that the problem of simultaneous data acquisition and electric control component calibration CAN be solved under the condition that the whole vehicle CAN and the calibration CAN are in different whole vehicle OBD interfaces. The connection is simple and convenient. The problem of for satisfying the function of carrying out data acquisition and automatically controlled part demarcation simultaneously, need two conventional single channel OBD to connect pencil and then the pencil connection that produces is loaded down with trivial details is solved. And (II) the double-channel OBD vehicle-mounted converter reduces purchasing cost, improves material management efficiency, simultaneously meets the requirements of CAN network connection of different whole vehicle OBD interface arrangement numbers and different whole vehicle OBD interface definitions, reduces conventional OBD connection wiring harnesses required to be purchased with various different specifications due to the whole vehicle OBD interface numbers and definitions, thereby reducing purchasing cost, reducing the number of purchasing parts, improving material management efficiency, and being suitable for industrial large-scale use and popularization.
