While maintaining growth in its traditional power cord business, Ningbo Youpu Electronics Co., Ltd. is actively expanding into the more technology‑intensive areas of wiring harness assemblies and electronic wires. The company’s latest product catalog shows that, in addition to conventional PVC power cords and plugs, it has obtained batch production qualifications for electronic wire types such as UL 1007, UL 1015, and UL 2464. It can also provide full‑process harness processing services, including tinning, overmolding, terminal crimping, and heat‑shrink tubing, according to customer drawings.

The rapid development of this business segment benefits from the company’s technical accumulation in internal connection solutions. For example, a harness assembly used in smart toilets needs to integrate a power cord, heating wire connections, and sensor signal wires into a single waterproof connector. Using its experience with plug molds, Youpu’s engineering team designed a two‑shot overmolding structure that achieves IPX4 waterproof rating and passes 10,000 flex tests. This product is now stably supplied to three sanitary ware manufacturers.

On the electronic wire side, the company has introduced semi‑automatic wire cutting/stripping machines and double‑end crimpers, capable of processing fine wires as small as 28 AWG, suitable for LED strips, drone internal connections, and medical monitoring equipment. To meet halogen‑free environmental requirements, Youpu has launched low‑smoke halogen‑free electronic wires and obtained relevant test reports. The harness workshop is also equipped with withstand voltage testers and continuity testers to ensure that every harness assembly is free of shorts and miswiring.

In terms of revenue structure, the share of harness and electronic wire business has risen from less than 10% in 2023 to 25% today. The company’s technical director revealed that a project for automotive‑grade harnesses (used for signal control in on‑board charging guns) has been initiated, and preliminary documentation for IATF 16949 certification is being prepared. Over the next three years, Youpu plans to operate the harness business as an independent brand, offering customers one‑stop service from design to mass delivery.
