Automotive waterproof connectors are sealed connection components dedicated to vehicle electrical systems. The product integrates conductive terminals, insulating shell and waterproof sealing structure, adapting to vehicle outdoor and wet working environment. All appearance size, pin bit, sealing structure follow automotive industry installation standards.
Product Introduction
ONLINK manufactures automotive waterproof connectors for vehicle wiring harnesses, lighting systems, electronic modules and new energy vehicle electrical assemblies. We integrate precision-stamped copper terminals, injection-molded insulating housings and rubber sealing components into complete sealed connector assemblies.
Our automotive connectors feature compression sealing and mechanical locking structures for electrical connections exposed to moisture, splashing water, dust and vehicle vibration. We manufacture connector housings, terminal arrangements and sealing interfaces to the required vehicle installation geometry, supporting custom automotive wiring and electrical equipment projects.
We provide connector manufacturing from terminal stamping and electroplating through plastic injection molding and final assembly. Our industrial and EV connector manufacturing capabilities also cover high-current conductive connections and modular electrical terminals.
We manufacture sealed automotive connectors with matching conductive, insulating and sealing components. Our custom production covers the connector mating structure, terminal cavities, sealing surfaces and installation features.

We manufacture automotive connector housings with integrated sealing structures that help protect the electrical connection from water and dust exposure. The housing design accommodates the conductive terminals, mating connector, rubber seals and locking components in one assembly.
Our waterproof connectors use silicone or rubber sealing elements installed within the connector structure. We manufacture the corresponding sealing grooves and compression interfaces so the seals fit the specified housing geometry.
The connector's waterproof performance depends on seal compression, terminal installation, housing fit and the finished mating assembly. We produce the sealing structure according to the project's environmental protection requirements and inspection conditions.
We manufacture terminal cavities and wire entry structures that accommodate the specified conductive terminals and automotive wiring arrangement. The terminal layout and rear sealing features are designed around the intended wire connections and connector installation space.
For complete cable-connected products, ONLINK also provides custom crimp wire harness assemblies with wire cutting, stripping, terminal crimping and connector assembly.
Our automotive waterproof connectors incorporate mechanical locking buckles to maintain engagement between mating housings. We manufacture the locking geometry and connector positioning features for vehicle electrical assemblies exposed to road vibration and repeated operating loads.
Connector retention depends on the mating housing, locking structure and assembly arrangement. We can manufacture customer-specific locking and installation features from approved connector designs.
For vehicle exterior electrical modules and lighting connections, we also consider the required installation orientation and available clearance when preparing housing tooling.
ONLINK combines metal and plastic component manufacturing for automotive waterproof connectors. We produce conductive terminals by precision stamping and electroplating, manufacture insulating housings by injection molding and assemble the sealing and locking components into the finished connector.
Our production work includes terminal forming, housing molding, terminal installation, seal positioning, connector locking assembly and finished-product checks. This integrated process supports connector orders requiring matched metal, plastic and elastomer components.
For connector systems requiring a permanently molded cable junction, we also manufacture waterproof overmolded wire harnesses.
We carry out assembly pressure resistance checks and sealing calibration for automotive waterproof connector production. Our products are manufactured for vehicle electrical environments involving moisture, dust, vibration, low temperature exposure and material aging.
For connector development and production acceptance, we work with the required sealing, mechanical and electrical inspection criteria, including the intended mating condition and environmental exposure.
When a project specifies a particular ingress protection rating or automotive test standard, the applicable test method, connector assembly condition and acceptance requirements should be included in the approved technical documentation. A sealed construction alone does not establish a specific IP rating.
We manufacture waterproof connector assemblies for several vehicle electrical systems:
Vehicle Body Wiring: Sealed connections for automotive body electrical circuits and wiring harnesses.
Automotive Lighting: Connector assemblies for vehicle lamp wiring and exterior lighting components.
New Energy Vehicles: Customized sealed connections for vehicle electrical wiring, including appropriately designed low-voltage and high-voltage applications.
External Electrical Modules: Connectors for vehicle-mounted electrical equipment exposed to moisture and environmental contaminants.
For high-voltage EV projects, electrical insulation, creepage and clearance distances, terminal ratings and applicable safety requirements are defined separately from waterproofing performance.
ONLINK manufactures custom automotive waterproof connectors for automotive electrical equipment manufacturers, wiring harness producers and vehicle component suppliers. We provide terminal forming, plastic housing production, sealing component assembly and finished connector manufacturing.
Send us your connector drawings or mating interface reference, terminal positions, wire specifications, housing dimensions, locking structure and required sealing conditions. Include the operating voltage, current requirements, environmental test criteria and estimated purchasing quantity for tooling and production quotation.
Yes. We manufacture connector housings and terminal layouts to the required mechanical and electrical drawings, including the specified terminal positions and mating interface.
Yes. We produce precision-stamped copper terminals, injection-molded insulating housings and the completed connector assembly with its sealing and locking components.
We manufacture sealed connector structures and carry out sealing checks. For a project requiring IP67, IP68 or another defined rating, provide the test standard and acceptance conditions so the connector design and verification requirements can be established. We do not apply one IP rating to every custom connector.
We also manufacture custom crimped wire harnesses and waterproof overmolded wire harnesses. Provide your connector, cable and assembly specifications for a combined manufacturing quotation.
Send us the mating interface drawing, terminal layout, wire size, voltage and current requirements, sealing standard, installation dimensions and estimated quantity.
ONLINK manufactures sealed automotive connectors, crimped wire harnesses and waterproof overmolded cable assemblies. We integrate conductive terminals, molded housings and wire connections for custom vehicle electrical systems.
