# LSR Overmolded LED Connector Sheath
---
LSR Overmolded LED Connector Sheath is a custom-molded liquid silicone rubber (LSR) protective component manufactured by Xiangchu (Hubei) Rubber Co., Ltd., designed to address common failure points of LED connector assemblies in harsh operating environments. This product is formed through precision liquid silicone injection overmolding directly onto rigid connector bases, creating a seamless, integrated protective layer that seals out moisture, dust, mechanical vibration, and temperature extremes.
As a specialized LSR product from our facility located at No. 54, Neihe Lane, Fankou Street, Echeng District Economic Development Zone, Ezhou City, Hubei Province, China, this overmolded sheath leverages the inherent advantages of LSR to outperform alternative protection solutions such as heat shrink tubing, epoxy potting, and plastic snap-on covers. Unlike assembly-added protection components, our overmolding process eliminates gaps between the sheath and connector substrate, preventing ingress pathways that commonly cause connector failure in outdoor and industrial LED applications. Our core focus on custom LSR molding allows us to produce these sheaths in custom geometries to fit any standard or proprietary LED connector design, matching the specific requirements of your lighting assembly.
All our LSR overmolded LED connector sheaths are produced from 100% cured, injection-molded liquid silicone rubber with the following base material properties:
Finished LSR overmolded sheaths meet the following baseline performance standards (custom adjustments available for special use cases):
Our overmolding process adheres to the following controlled parameters to ensure consistent part quality:
The overmolding process bonds LSR directly to the connector substrate, creating a monolithic structure with no gaps, seams, or assembly tolerances that can allow water or dust ingress. This delivers consistent IP67-level protection when properly designed, outperforming multi-component assembled protective solutions that are prone to seal failure over time. This seamless construction also prevents wicking of moisture along connector pins, a common cause of LED system short circuits.
LSR maintains its elastic and insulating properties across a wide temperature range, making the sheath resistant to cracking in cold outdoor environments and softening or degradation in high-heat applications such as high-power industrial LED lighting. The flexible LSR material also absorbs mechanical shock and vibration from transportation, installation, and long-term operating conditions, reducing stress on connector pins and internal wiring to extend the service life of the entire LED assembly.
Unlike thermoplastic and organic rubber materials, LSR is inherently resistant to UV radiation and ozone degradation, making the sheath ideal for long-term outdoor exposure. It will not yellow, crack, or become brittle after years of outdoor use, maintaining protection and appearance for the full service life of the LED system. This weather resistance eliminates the need for additional UV-stabilizing coatings that can add cost and wear over time.
Liquid silicone injection overmolding supports complex geometries, tight tolerances, and small to large production runs, allowing us to match almost any LED connector design – from small PCB-mounted connectors for indoor LED strips to large power connectors for high-bay industrial lighting. We can adjust hardness, wall thickness, and material grade to match your specific assembly and performance requirements, with no expensive tooling modifications for minor design adjustments.
Our LSR materials have excellent dielectric properties and consistent insulating performance even in high-humidity environments. They are free of conductive contaminants that can cause short circuits, and maintain stable insulation resistance across the full operating temperature range of LED systems.
LSR overmolded LED connector sheaths are suitable for a wide range of LED lighting applications where connector protection is critical:
We produce custom-sized LSR overmolded sheaths to match your connector dimensions, with common outer diameters ranging from 5 mm to 50 mm and wall thickness from 1 mm to 5 mm. Tighter tolerance requirements can be accommodated based on your design specifications. Please provide your connector 2D/3D drawings for accurate quoting and sample production.
Xiangchu (Hubei) Rubber Co., Ltd. operates a quality management system certified to ISO 9001, with strict in-process and final quality controls for every batch of LSR overmolded LED connector sheaths. Our quality testing includes:
