What is an electronic wiring harness?
In the most popular words, the electronic wiring harness uses wires that electronically control input and output.
Manufacturing technology of electronic wiring harness;
1. wire cutting: check whether the standard type of wire is correct; Does the scale meet the demand?
2. Peeling: Check whether the peeling port is uniform, whether the core wire and the group wire can not be peeled, and whether the peeling scale is correct.
3. Grouping treatment: whether the trimming ratio is correct or not, whether the trimming is uniform or not, and do not hurt the core wire when trimming and grouping.
4. Peeling endothelium: check whether the peeling is uniform; Whether the peeling scale is correct; Whether the core wire has peeling damage or copper wire fracture; Insulators cannot fall off during half stripping.
5. Set shortening pipe: check whether the scale and model of shortening pipe are correct.
6. Prepare solder: check whether the temperature of the tin furnace is correct; Whether the copper wire of the core wire is arranged well before preparing the solder, and whether it has the appearance of bifurcation, twists and turns, discount, etc. After preparing the solder, is there any appearance such as bifurcated copper wire, big head, uneven copper wire and scalded insulation skin?
7. Welding: Check whether the soldering iron temperature is correct; Don't burn the insulation skin, the tin spot should be lubricated and sharp, and false welding and virtual welding are not allowed.
8. Terminal crimping: acknowledge whether the standards of terminals and wires are correct; Whether the terminal is pressed with bell mouth, skew, exposed insulation skin and core wire is too long or too short.
9. Terminal penetration: check whether the connector and terminal types are correct; Whether the terminal is damaged or deformed; Whether the terminal is missing, incorrectly inserted or incorrectly inserted.
10. Cable crimping: check whether the connector type is correct; Whether the cable direction is correct; Whether the core wire is damaged, exposed to copper or burnt; Is the crimping in place?
1 1. Blowing short pipe: the short pipe protrudes, and the heat preservation is not paste.
12. Assembling the shell: whether the shell has defects such as wrong assembly, scratches and burrs, whether there are missing parts, whether the screws are tightened, oxidized, discolored and loosened, and whether there are nonconformities after assembly; If the shell is oriented, it must be assembled as required.
13. Labeling: check whether the contents of the label are correct, clear and free of word breaks; Whether the scale of the label is correct; Whether the label is dirty or damaged; Whether the direction of the label is correct.
14. Tie a tie: check whether the standard, color and orientation of the tie are correct; No cracks or looseness.
15. injection molding: check whether there is dirt, lack of materials, bubbles, poor adhesion and hardening on the mold.
16 plug molding: check whether the plug molding has defects such as breakage, unevenness, lack of materials, burrs, sundries, streamline, etc., and acknowledge that the metal terminal has no defects such as deformation, breakage and copper exposure.
17. electrical inspection: according to the inspection instruction requirements of the corresponding goods.
18. Visual inspection: Pay attention to all visible items.
In the above article, we have made a comprehensive introduction to what is the information of electronic wiring harness, and explained the processing flow in detail. From the above, we can roughly understand what an electronic wiring harness is and the process steps. Electronic wiring harness is essential in today's society. Although most people don't know this term, almost everyone has seen it. In our common household appliances and computers, electronic wiring harness also plays a very important role in these electronic products. It is also necessary for us to know about it.
