Car Door Wiring Harness Bellows Description
Car Door Wiring Harness Bellows Definition & Uses
A bellows is a type of pipe with a concave-convex corrugated shape that is used in the part of the wire harness that is more subjected to mechanical shock. Its main role in automotive wiring harnesses is to protect the wires from functional failures due to wear or mechanical shock.
| Material | Operating temperature | Flammability rating |
| PA, PP, PE | -40°C to 150°C | FV-0 |
Bellows Material
The material of the bellows is generally PE, PA6/66, PP, etc., and the temperature resistance range ranges from -40°C to 150°C. PA material has better performance in flame retardancy and wear resistance, while PP material has advantages in bending fatigue resistance.
Bellows Type
Ordinary bellows: economical and practical.
High elastic bellows: suitable for environments with high wear resistance requirements, such as tractors, etc.
Double-threaded bellows: Provides additional protection and abrasion resistance.
Bellows design requirements
The automotive wiring harness bellows can be customized into four types: ordinary, heat-resistant, flame-retardant, heat-resistant, and flame-retardant according to the use of the engine compartment. The color is usually black, but there are also yellow, gray, etc., which can be customized according to customer needs.
The principle of the bellows arrangement
The wiring harness should be avoided from sharp objects, metal frame edges, weld seams, and fixing holes in the body, especially in the corners to protect against wear.
The wiring harness should be arranged on the dry side of the door as much as possible to prevent the impact of water leakage on the wiring harness.
In areas with strong electromagnetic interference, anti-magnetic protection is added to the wiring harness, and special wires such as twisted pairs or shielded wires can be used.
Bellows Market Analysis
In the market, there are foreign brands such as Shelham, DELFINGEN, and Franxi, as well as domestic brands such as Tuoyan, Nanjing Ninghe, etc. Foreign brands pay more attention to synchronous development capabilities, while domestic brands have advantages in delivery cycle, price, and service.
Through the above information, you can understand the basic concept, material type, design requirements, and market situation of Car Door Wiring Harness Bellows. This information helps to have a comprehensive understanding of the Car Door Wiring Harness Bellows.
