Embodiment １

[0024] Figure 1 and figure 2 As shown, the OBD data connection line provided by the present invention includes a diagnostic socket plug 1, a first data line 2 and a second OBD plug 5, and the diagnostic socket plug 1 and the second OBD plug 5 are respectively connected to the first data line 2 The two ends of the first power line 6 are also included, and the first data line 2 is only built with a data transmission line. One end of the first power line 6 is connected to the power pin of the second OBD plug 5. The first power line 6 The other end of the ACC power supply plug 9 is also connected.

[0025] The set diagnostic socket plug 1 is used to connect the on-board automatic diagnosis system, the second OBD plug 5 is used to connect the OBD diagnostic head, and the first data line 2 is used for data transmission between the on-board automatic diagnostic system and the OBD diagnostic head. The ACC power plug 9 is used to connect the ACC circuit of the car, that is, the power...

Embodiment ２

[0027] This embodiment is further limited on the basis of Embodiment 1, as shown in Figure 1 and figure 2 , also includes a second data line 3 and a first OBD plug 4, the two ends of the second data line 3 are respectively connected to the diagnostic socket plug 1 and the first OBD plug 4.

[0028] The first OBD plug 4 is set as a spare interface. This setting makes it necessary to connect the first OBD plug 4 to the peripheral device when the OBD diagnostic head needs to be checked, updated, or other data is read from the OBD diagnostic head. , the connection between the OBD diagnostic head and peripheral equipment can be realized, so that the operator does not need to disassemble the OBD diagnostic head and pull out the second OBD plug 5, so that the OBD diagnostic head can continue to analyze and process various data on the car , and improve the efficiency of system detection and updating of the OBD diagnostic head or other data reading of the OBD diagnostic head.

Embodiment 3

[0030] This embodiment is further limited on the basis of Embodiment 2, as shown in Figure 1 and figure 2 , also includes a second power line 7, the two ends of the second power line 7 are respectively connected to the power pin of the diagnostic socket plug 1 and the power pin of the second OBD plug 5, and the second power line 7 is also connected in series with the first Two power cord plugs 8 .

[0031] Both the first data line 2 and the second data line 3 include a plurality of signal lines 10 and a signal line wrapping layer wrapping the plurality of signal lines 10 together, the signal line wrapping layer has a two-layer structure, and the signal line wrapping layer The layers include an insulating layer 11 as an outer layer and a shielding layer 12 as an inner layer.

[0032] The shielding layer 12 is aluminum foil or a metal mesh formed by intertwining a plurality of thin metal wires.

[0033] The set second power line 7 is used to connect the power pin of the diagn...

Abstract

The invention discloses an OBD data connecting line. The OBD data connecting line comprises a diagnosing base plug (1), a first data line (2) and a second OBD plug (5). The diagnosing base plug (1) and the second OBD plug (5) are connected to the two ends of the first data line (2) respectively. The OBD data connecting line further comprises a first power line (6). The first data line (2) is only and internally provided with a data transmission line, one end of the first power line (6) is connected to a power contact pin of the second OBD plug (5), and the other end of the first power line (6) is connected with an ACC power plug (9). The power supply mode of an OBD diagnosing head is changed, the runtime of a storage battery of an automobile can be prolonged, and the burden of a power module and a filter circuit of an automatic vehicle-mounted diagnosing system can be relieved.

Description

technical field [0001] The invention relates to the field of connecting wires for automobiles, in particular to an OBD data connecting wire. Background technique [0002] With the continuous development of the automobile industry and the enhancement of people's awareness of environmental protection, OBD, that is, "on-board automatic diagnostic system", can monitor whether the exhaust gas of the car exceeds the standard at any time from the operating status of the engine. Once it exceeds the standard, it will immediately issue a warning; when the system fails At the same time, the fault (MIL) light or check engine warning light is on, and the powertrain control module (PCM) stores the fault information into the memory, and the function of reading the fault code from the PCM through a certain program is widely used in modern vehicles. on the car. [0003] The OBD data connection line is used for the connection between the on-board automatic diagnosis system and the OBD diagno...
