Manufacturers share the production precautions for connectors:
1. Cutting: Check if 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. The wires should be free of dirt and other conditions.
2. Peeling: Check if the peeling opening is flush, do not damage the core wire, grouping wire, etc., and ensure that 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 insulator must not come off during semi stripping.
5. Set shrink tubing: Check if the size and model of the shrink tubing are correct.
6. Preparation for soldering: Check if the temperature of the tin furnace is correct; Before preparing for soldering, whether the copper wire of the core wire is properly organized, and whether there are any forks, bends, or folds; Is there any phenomenon of copper wire branching, large ends, uneven copper wire, or scalding of insulation skin after preparing for soldering.
7. Soldering: Check if the temperature of the 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; Is there any horn mouth, tilt, insulation skin, or exposed core wire when pressing the terminal.
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, misplaced, or improperly inserted 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 shrink tubing: Check if the shrink tubing 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 without any word breaks; Is the size of the label correct; Whether the label is dirty or damaged; Is the label pasted in the correct position.
14. Tie straps: Check if the specifications, colors, and positions of the tie straps are correct; No breakage or loosening phenomenon.
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 Forming: Check for damage, unevenness, material shortage, burrs, debris, flow lines, and other defects in the plug forming, and confirm that the metal terminals are free of deformation, damage, exposed copper, and other defects.
17. Electrical inspection: Conduct inspections according to the inspection instructions for the corresponding products.
18. Appearance inspection: Pay attention to inspecting all visible items. 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 the 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 good pressed condition, whether there is any missing or incorrect insertion, and whether the insertion is in place; Is the crimping condition of the wiring good; Whether the shrinkage of the heat shrink tubing is good, and whether the shrinkage position and size are correct; Check if the specifications, quantity, and position of the zip ties are correct and if they have fallen off.
