Here is the English translation of the provided text, using professional terminology from the wire harness industry:
Energy storage wire harnesses consist of wires, terminals, connectors, and accessories, serving as carriers for input/output currents and signals. Common accessories include magnetic rings, tapes, cable ties, and labels. Currently, there are four main types of wire harnesses produced:
Display screen harnesses: Primarily used for the driving lines of various display screens, mainly applied in the display screen field;
Control harnesses: Mainly used to connect circuit boards and control electrical signals in financial equipment, security equipment, new energy vehicles, medical devices, and other fields;
Power cables: Such as switch power cables and computer power cables.
Data cables: Used for uploading and downloading signals, such as MINI, MICRO, Samsung, and Apple data cables.
Energy storage wire harness manufacturers state that with the development of industrial intelligence and China's rise as an industrial powerhouse, wire harnesses act as the blood vessels and nerves of industrial equipment. Market demand will continue to grow, quality requirements will become increasingly stringent, and technical demands will become more complex. For wire harness processing plants, opportunities and challenges coexist.
The general operational process for processing energy storage wire harnesses includes wire cutting, stripping, stripping the wire ends, terminal crimping, tinning, housing insertion, soldering, packaging, testing, visual inspection, and warehousing. It can be said that every process is crucial and involves many precautions, directly determining the overall quality of the wire harness.
Precautions for processing energy storage wire harnesses:
Production line requirements: The length of the wire must be within the specified tolerance range. Wires that are too long or too short cannot be passed on to the next process;
Stripping requirements: There are also length requirements for stripping, and the inner core wires must not be damaged;
Stripping length requirements: The length of the stripped wire end is directly related to the terminal specifications. Terminals that are too short or too long will result in unqualified crimping;
Terminal crimping: This is a critical step. The pull force must meet the standards, and the appearance of the terminals must be re-inspected;
Tinning: The tinning must be fully filled with solder. Defects such as frayed strands, split strands, or large solder joints are strictly prohibited; otherwise, the product is unqualified;
Housing insertion: Terminals are prone to being inserted incorrectly or not fully seated. There must be no cold solder joints, missing solder, or incorrect soldering;
Protective tubing: This includes heat shrink tubes, PVC tubes, corrugated tubes, and fiberglass tubes, all of which have strict requirements for dimensions and processing techniques;
Testing: Includes continuity testing, resistance, and voltage testing. Products that do not meet the requirements are considered defective. Visual inspection serves as a supplementary check to previous processes. If the overall appearance inspection of the wire harness is unqualified, it must be returned for rework;
Packaging and warehousing: Proper packaging and storage of each wire harness during the warehousing process are equally important; otherwise, qualified products may become defective.
