Precautions for connector production

Precautions for connector production:
1. Wire cutting: Check whether the specifications and models of the wires are correct; Whether the size meets the requirements; The incision must be flat and not scratch the wires, and the wires must be free of dirt and other conditions.
2. Peeling: Check if the peeling opening is flush, and do not damage the core wire, marshalling wire, etc. The peeling size is correct.
3. Grouping processing: Check whether the trimming size is correct, whether the trimming is flush, and do not damage the core wire when trimming the grouping.
4. Peeling the endothelium: Check if the peeling opening is flush; Whether the peeling size is correct; Is there any damage to the core wire or broken copper wire; The insulation must not come off during semi stripping.
5. Sleeve shrink tube: Check if the size and model of the shrink tube are correct.
6. Preparation for soldering: Check if the temperature of the soldering furnace is correct; Before preparing for soldering, whether the copper wire of the core wire is well organized, and whether there are any forks, bends, or folds; Is there any phenomenon of copper wire forking, large end, uneven copper wire, and insulation skin scalding after preparing for soldering.
7. Soldering: Check if the temperature of the electric soldering iron is correct; Do not burn the insulation skin, the tin points should be smooth and pointed, and false or false soldering is not allowed.
8. Terminal pressing: Confirm whether the specifications of the terminals and wires are correct; Check if the terminal is pressed with a bell mouth, tilted, and if the insulation skin and core wire are exposed too long or too short.
9. Terminal insertion: Check if the connector and terminal model are correct; Check for any damage, deformation, or other phenomena on the terminals; Check for any missing, incorrect, or inadequate insertion of terminals.
10. Cable crimping: Check if the connector model is correct; Is the direction of the wiring correct; Whether the core wire is damaged, exposed to copper, or burned; Whether the crimping is in place.
11. Blow the shrink tube: Check if the shrink tube shrinks well and do not burn the insulation skin.
12. Assembling the shell: Check whether the shell is installed incorrectly, whether there are scratches, burrs, and other defects, whether there are missing components, whether there are screws that are twisted, oxidized, discolored, loose, and other defects, and whether there are no matching defects after assembly; If the shell is directional, it must be assembled according to the requirements.
13. Labeling: Check whether the content of the label is correct, clear, and free of hyphenation; Is the size of the label correct; Whether the label is dirty or damaged; Is the label pasted in the correct position. 14. Binding tape: Check if the specification, color, and position of the binding tape are correct; No breakage or looseness.
15. Injection molding: Check whether there is dirt on the mold, and whether there are missing materials, bubbles, poor bonding, and hardening defects in the molding area.
16 Plug molding: Check the plug molding for damage, unevenness, material shortage, burrs, debris, flow patterns, and other defects, and confirm that the metal terminals are free of deformation, damage, exposed copper, and other defects.
17. Electrical inspection: Conduct the inspection according to the requirements of the corresponding product inspection guide ticket.
18. Appearance inspection: It should be noted that all visible items should be inspected. For example, checking whether the product size meets the requirements; Whether the wrong materials are used, and whether there is excessive or insufficient use; Check the surface of wires and connectors for scratches, stains, burrs, deformations, gaps, and other defects; Whether the connector fixing parts are missing and whether the shell assembly is in good condition; Whether the content of the label is correct and clear; Whether the position and direction of the label are correct; Whether the terminal is in a good pressed state, whether there is any missing or incorrect insertion, and whether the insertion is in place; Whether the crimping condition of the cable is good; Whether the shrinkage of the heat shrink tube is good, and whether the shrinkage position and size are correct; Check if the specifications, quantity, and position of the tie are correct and if there are any drops.
