Rear market maintenance personal afterwards provides diagnosis and supports, is quickly positioned to failure, convenient for the repairing to vehicle.
Chinese utility model patent is disclosed, publication number: CN108242751A, patent name: adapter and onboard diagnostics
System, the applying date: 20171229, it discloses a kind of adapter and onboard diagnostic systems.The adapter includes shell, in shell
It is provided with the male connector connecting for the diagnostic socket with onboard diagnostic system and the mother for connecting with onboard diagnostic system terminal
Head, the male connector include at least two root cutting needles, which includes at least two pin holes, and each contact pin and each pin hole correspond, this turn
Connector further includes the electric connection structure for each contact pin and corresponding pin hole to be electrical connected, and each contact pin is in the position on shell
It is correspondingly arranged in the position on shell in 180 degree rotation with corresponding pin hole.Compared with prior art, it is set in the shell of the adapter
It is equipped with male connector and female, male connector is inserted into the diagnostic socket of onboard diagnostic system, and onboard diagnostic system terminal is inserted into female, energy
The direction for enough changing onboard diagnostic system terminal internal antenna, to improve the ability of onboard diagnostic system terminal received signals.
In vehicle development phase, domestic vehicle factor generally existing the case where not defining each stitch by standard, especially CAN line
Definition, in addition to standard 6 high 14 it is low other than, there is also 3 high 11 low and 1 high 9 low situations, if using the OBD male connector of standard
Interfacing device, CAN line will be unable to normal communication, and when more technology companies research and develop jointly, engineer may put down thus
Add many workloads.
In vehicle development phase, engineer needs and automobile ECU real-time communication, such as external ETAS-590, ETAS-592
Etc., it is supported in addition to needing the rim of the mouth OBD to provide CAN communication, it is also necessary to provide 12V/24V direct current by external power supply box for equipment
Electricity power supply, wiring is more, inconvenience.
In vehicle development phase, it is often necessary to CAN line simultaneously with multiple equipment real-time communication, such as with ETAS-592 communicate
Each monitoring quantity of ECU is recorded, while being also required to the CAN frame received and dispatched with CAN case Communication Monitoring ECU, the rim of the mouth OBD of standard mentions
The CAN line interface of confession is inadequate.
