Product introduction

Harness material selection

The quality of the wire harness material directly affects the quality of the wire harness. The choice of wire harness material is related to the quality and service life of the wire harness. Remind you all, don't be greedy for the choice of wire harness products. Cheap wire harness products may use inferior wire harness materials.

Parameters:

How to distinguish the quality of the harness? Understand the material of the wiring harness. The following is the material of wire harness selection.

The wiring harness is generally composed of wires, insulating sheaths, terminal blocks and packing materials. As long as you understand these materials, you can easily distinguish the quality of the harness.

1. Material selection of terminal

The copper used for terminal materials (copper parts) is mainly brass and bronze (brass is slightly lower in hardness than bronze), of which brass accounts for a larger proportion. In addition, different coatings can be selected according to different needs.

2. the choice of insulating sheath

The commonly used materials of sheath material (plastic parts) are PA6, PA66, ABS, PBT, pp, etc. According to the actual situation, flame retardant or reinforcing materials can be added to the plastic to achieve the purpose of reinforcing or flame retardant, such as adding glass fiber reinforcement.

3. the choice of wire harness

According to the different use environment, choose the corresponding wire material.

4. the choice of dressing materials

The wire harness bandage plays the role of wear resistance, flame retardant, anticorrosion, interference prevention, noise reduction, and beautification. Generally, the bandage material is selected according to the working environment and the size of the space. There are usually adhesive tapes, corrugated pipes, PVC pipes, etc. in the choice of packing materials.

Wire harness production process:
1. Wire cutting: Check whether the standard type of wire is correct; whether the scale meets the requirements
2. Peeling the skin: Check whether the peeling opening is flush, can not peel the core wire, marshalling wire, etc., and the peeling scale is correct.
3. Marshalling treatment: is the trimming scale correct, is the trimming level, and the core wire cannot be injured when trimming the marshalling.
4. Peeling the inner skin: check whether the peeling opening is flush; whether the peeling scale is correct; whether there is peeling core wire, broken copper wire; the insulator cannot fall when half peeling.
5. Set of shortened tubes: check whether the size and type of shortened tubes are correct.
6. Prepare solder: check the temperature of the tin furnace is correct; whether the copper wire of the core wire is sorted before solder preparation, whether there are bifurcations, twists and turns, and other appearances; after the solder preparation, is there any copper wire bifurcation, The appearance of big head, uneven copper wire and scalded insulation.
7. Soldering: Check whether the temperature of the soldering iron is correct; the insulation skin cannot be scalded, the tin point should be lubricated, no tin tip, no false soldering, no virtual soldering.
8. Crimping of the terminal: It is recognized whether the standard of the terminal and the wire is correct; whether the terminal is crimped, whether there is a bell mouth, skew, insulation and core wire is too long or too short.
9. Terminal puncture: Check whether the connector and terminal type are correct; whether the terminal is damaged or deformed; whether the terminal is missing, wrongly inserted, and the puncture is not in place.
10. Cable crimping: check whether the type of connector is correct; the direction of the cable is correct; whether the core wire is damaged, exposed copper, or burnt; whether the crimping is in place.
11. Blowing shortening tube: Is shortening the shortening of the tube outstanding, not to scald the insulation.
12. Assembling the shell: Is the shell installed incorrectly, is there any scratches, burrs and other defects, is there any missing components, whether the screws are unscrewed, oxidized, discolored, loose, etc., and there is no defective after assembly; if the shell is Direction, then it must be assembled according to demand.
13. Labeling: Check whether the content of the label is correct, clear and unbroken; the label is correct; the label is dirty or damaged; the orientation of the label is correct.
14. Tie the tie: check whether the standard, color and orientation of the tie are correct; no cracks or loose appearance.
15. Injection molding: check whether there is dirt on the mold, whether there is lack of material, air bubbles, poor adhesion, poor curing, etc. in the molding part.
16 Plug molding: Check the plug molding for damage, unevenness, lack of material, burrs, debris, flow patterns and other defects, and admit that the metal terminals are not deformed, damaged, exposed copper and other defects.
17. Electric View: View in accordance with the requirements of the corresponding product's viewing guide ticket.
18. Appearance view: pay attention to all items that can be seen as long as they are visible.
