18. Appearance view: Be careful to view all items that can be seen.
Common parameters and models of Custom Wiring Harness
- The wire harness is also called arbitrarily selecting the number and spacing of the wires, which makes the connection more convenient, greatly reduces the volume of the electronic product, reduces the production cost, and improves the production efficiency.
- It is most suitable for moving parts between the motherboard and the PCB board to the PCB board, used in small-scale electrical equipment for data transmission cables.
- It is understood that it is widely used in the connection between various printer print heads and motherboards, signal transmission and board connection of plotters, scanners, copiers, stereos, LCD appliances, fax machines, various DVD players and other products.
- In modern electrical equipment, there is almost nowhere. Common specifications of various pitch flexible wires are such as 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, and 2.54mm.
What are the requirements for environmentally friendly Custom Wiring Harness?
Adopting green environmental protection insulation layer, sheath and special oxygen barrier material, it not only has excellent motor energy and physical mechanical function, but also guarantees that the product does not contain halogen, and its secondary pollution caused by incineration avoids the traditional PVC.
Carcinogenic “dioxin” material occurs when the wire is incinerated.
2. Low toxins:
Insulation and sheath do not contain lead, cadmium and other heavy metals harmful to the human body, and will not pollute the soil or water source when the electronic wire is used and discarded. And after the harsh toxicity test, the white mouse is safe under the premise of the prescribed test.
3. No corrosive air:
Adopting new special coating materials that are environmentally friendly, no toxic air such as HCl will occur during the production, utilization process and incineration, and the amount of acid gas emitted will be small, and the damage to personnel, equipment and instruments will be small, and the environmental characteristics will be more obvious.
4. High flame retardancy:
The environmental protection electronic line fully guarantees the construction conditions for high fire-fighting conditions. The electronic wires are not easy to be burned during the fire and can prevent the flame from expanding and the expansion of disasters after incineration.
5. High transmittance:
The smoke generated when the electronic wire is incinerated is extremely thin, which is conducive to the evacuation of personnel and the work of fire fighting. The light transmittance of the product is more than 40%, which is much higher than the standard of the light transmittance of the traditional flame retardant type electronic wireless than 20%.
6. Waterproof and UV resistant:
Take green environmental protection materials that are not in the same layout as ordinary people to ensure ultra-low water absorption. The extraordinary UV absorber makes the product have excellent UV protection. It ensures the safety of the use of such products and delays the service life.
The first company to launch the name of “environmental electronic line” is a Japanese company whose product scale is the fn (eco material) environmental electronic line scale.
The western countries also set the leading environmental protection electronic line scale conditions in the UK, and gradually expand in the future to the world.
What are the characteristics of custom high-quality wire harness?
The wire harness belongs to the weak electric cable, which is the internal connecting wire of the electrical equipment. At present, the main wire harness on the market mainly includes 3C, VED and UL standards.
The wire harness is used for the connection inside the appliance, so its conductive function is very important. If the current of the wire harness is unstable, it will cause the unstable performance of the appliance. Therefore, this must be taken care of when purchasing. Let’s take a look at what the high-quality wire harness is like:
1. Smooth surface, no black line, no chaotic line, no pitting, no oxidation, no smudge, no scratches, no tin plating (sticky tin, leaking tin), no slash, no hand joint, No fingerprints.
2. The surface of the copper wire is not sticky after the terminal wire is rolled (overfilled)
3. The tension of the terminal wire is moderate but loose or too tight.
4, the wire harness is good, uniform, no stacking, underside (low side of the side or low side of the two sides), no stocks.
Custom Wiring Harness quality inspection method
The wire harness refers to the wire inside the electrical equipment, and the wire harness belongs to the weak electric cable, which is widely used in weak electrical engineering. The inner conductor of the electronic wire is generally tinned copper or bare copper.
The data lines that we often use and the wires inside the electronic products are the terminals connecting wires. The wires have strict quality standards, and the quality of the product must be checked when selecting the terminal wire. The following is a description of the quality test method for the wire harness:
1. Check the certification mark. Products with a wire harness that should be compulsory certified shall be marked with a certification mark in the prominent position of the product, that is, “CCC”, “UL” and “ROHs” mark. Otherwise, it is an unlicensed product.
2, the length. The national standard specifies the delivery length of the wire harness. The length of the loop should be 100m, and the length of the disc should be greater than 100m. The consumer can measure according to the length of the label. The standard stipulates that the length error does not exceed 0.5% of the total length.
If it does not reach the lower limit of the standard, it will be unqualified. The length of the terminal wire is 610m/volume, and each label has a note.
3. Observe the wire finish and colour. wire harness the copper conductor is metallized or non-metallized annealed copper wire. The aluminum conductor is aluminum or aluminum alloy wire. The surface is smooth, the copper conductor is light purple, and the aluminum conductor is silvery white.
Otherwise, the conductor is likely to be doped with other impurities. , causing a drop in electrical conductivity.
4. Measure DC resistance. In order to ensure the quality of the purchased wire harness, you can first take 3 – 5 meters from the product you want to purchase to the inspection mechanism for DC resistance measurement.
5. Look at the inspection report. As a product that affects the safety of people and property, the wire harness has been listed as the key point of government supervision and inspection. The regular manufacturers are inspected by the supervision department on a periodic basis. Therefore, the seller should be able to provide the quality inspection department inspection report, otherwise, the quality of the product will lack a basis.
6. Detect insulation and sheath. The insulation of the wire harness and the thickness of the sheath should be uniform and unbiased, and the hand induction has obvious tension and elongation. At the same time, the surface of the insulation and sheath should have a continuous printing mark of the name of the manufacturer and the type of the product. The mark interval: the insulation does not exceed 200mm, and the sheath does not exceed 500mm.
