Automotive Waterproof LSR Overmolded Connector Housing

Automotive Waterproof LSR Overmolded Connector Housing is designed around the requirements of this LSR overmolded connector housing can be used in:. As a electronic and electrical assembly component, the design is defined by material: PA66, PA66+GF, PBT, PPS, LSR Silicone, Custom Materials; process: Plastic Injection Molding + LSR Overmolding; silicone hardness: Customizable, commonly 30–70 Shore A and should be evaluated as part of the complete product or equipment assembly.

The page is structured for B2B sourcing: first the functional highlights, then the documented material or process data, followed by application and customization information where it is available. This makes the technical requirements easier to review during supplier qualification.

Key Engineering Benefits

• The LSR sealing structure provides flexible compression and close contact with the mating connector, helping protect the internal terminals from water, dust, moisture, and external contamination.
• The connector housing can be designed with locking clips, secondary locks, positioning structures, guide slots, and anti-misassembly features to ensure stable connection during vehicle operation.
• The product is designed for applications exposed to vibration, temperature change, humidity, dust, and long-term electrical system operation.

Frequently Asked Project Questions

Can this silicone seal be overmolded directly onto the plastic connector housing?

Yes. LSR can be directly overmolded onto suitable plastic materials to form an integrated sealing structure. Material compatibility should be confirmed during product development.

What plastic materials are commonly used for automotive connector housings?

Common materials include PA66, PA66+GF, PBT, PPS, and other automotive-grade engineering plastics. The final selection depends on temperature resistance, strength, insulation, and application environment.

Can this product be customized based on our connector design?

Yes. We can customize the connector housing, LSR sealing area, color, hardness, locking structure, and terminal layout based on drawings, samples, or 3D files.

RFQ and Drawing Review

Because these components are application-specific, the drawing and assembly conditions remain the controlling documents. The product information above is best used to define the initial RFQ scope and identify the items that need confirmation before tooling or mass production.
