New energy vehicles and intelligent connected vehicles are rewriting the bill of materials of the whole car. As the "nerve system" of the vehicle's electrical architecture, automotive connectors are seeing demand climb across powertrain, body control and infotainment domains - and industry data shows a single NEV can carry 3 to 5 times more connectors than a conventional fuel vehicle.

Waterproof wire-to-board connectors - sealed signal and power transmission for body electronics
For body control modules, the connector is exposed to water splash, dust, vibration and thermal cycling. That is why our waterproof wire-to-board series is engineered around three things:
Tianwan Electronics focuses on automotive connectors and offers a compact but complete portfolio for in-vehicle electronic control units:
| Product line | Series | Typical applications |
|---|---|---|
| Waterproof wire-to-board connectors | Sealed PCB headers with mating wire harness connectors | BCM, door modules, exterior lighting |
| Wire-to-board connectors | 1.0 mm / 1.8 mm / 3.0 mm pitch PCB headers & mating housings | TBOX, window control, seat control, instrument clusters |
| Custom plastic housings | Custom moulding from customer drawings | ECU enclosures integrated with the connector interface |
Because we mould the housing and stamp and assemble the terminals in one plant, the connector and its enclosure are engineered as one assembly - a good fit for customers who want the housing and the board-end header supplied together.
Backed by our production base Henan Jinhua Electric Co., Ltd. - an IATF 16949 certified plant with 13,000 m² of floor space and 22 patents - we run a strict quality control system together with flexible customization capability. Tier 1 and Tier 2 suppliers rely on us for standard series supply as well as fast-turn custom development.
As domestic substitution accelerates in China's automotive supply chain, buyers are actively looking for local connector partners who can combine independent R&D, quick engineering response and stable mass production. That is exactly where our strength lies: in-house mould building, short sampling cycles and direct factory communication.
