Joint chair is controlled by the SCM system of enclosure interior and relay circuit board.
Compared with prior art, the utility model has the beneficial effects that the utility model is suitable for test M7.8 EFI system
The gasoline engine machine frame harness of the lower various models of system, convenient test is quick, result is accurate, securely and reliably, stability
It is good, easy to operate, practical, strong guarantee is provided for the research and development of product.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the novel engine pedestal harness checking instrument of the utility model；
Fig. 2 is the schematic diagram of harness checking instrument shown in FIG. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in the utility model carry out it is clear,
It being fully described by, it is clear that described embodiment is only a part of the embodiment of utility model, instead of all the embodiments,
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Fig. 1 ~ Fig. 2, the utility model discloses a kind of novel engine pedestal harness checking instruments, including shell
11, LCD display 1, LCD brightness regulation knob 2, extension control keyboard 3, power switch 4, SCM system switch 5, thermal column
Grid 7, rack harness connector 8, attaching plug 9, harness school inspection pen 10 and multiple harness attachment bases 6, the shell 11 are length
Cube shape, 11 upper surface of shell are equipped with power switch 4, SCM system switch 5, extension control keyboard 3, LCD brightness regulation
Knob 2, LCD display 1 and multiple harness attachment bases 6,11 one side of shell are equipped with heat dissipation barrier 7, and 11 1 end face of shell is set
There is rack harness connector 8 and is connect with attaching plug 9 and harness school inspection pen 10, the LCD display 1, the rotation of LCD brightness regulation
Button 2, extension control keyboard 3, power switch 4, SCM system switch 5, heat dissipation barrier 7, rack harness connector 8, power supply are inserted
First 9, harness school inspection pen 10 and multiple harness attachment bases 6 are by the SCM system (51 single-chip microcontroller) 12 and 8 inside shell 11
The control of × 8 relay circuit boards 13.
The utility model application method:
1, rack harness to be detected is taken to dock with rack harness connector 8；
2, power on plug 9, turn on the power switch 4, open SCM system switch 5, LCD display 1 is opened at this time；
3, line taking Shu Jiaojian pen 10 starts to test, and connects each plug of wiring harness sensor, observes the feelings of LCD display 1
Condition；
4, lead to the utility model cisco unity malfunction if there is fortuitous event, multimeter is taken to connect by multiple harness
