Injection Molded ABS Plastic Electrical Connector Insulator Shell

1. Product Name
ABS Plastic Terminal Housing / Wire Connector Insulator Cap

 

2. Product Category
Electrical Accessories & Plastic Injection Molded Components

 

3. Product Description
This electrical housing component is engineered to encase and protect pin terminals or wire connectors. Molded from high-impact ABS resin, it features internal slots and retention features that snap onto terminals securely, preventing accidental pull-out or short-circuiting. The square backend and cylindrical insertion end allow for panel mounting or inline wire housing, with distinct color coding (red/black) facilitating easy positive and negative polarity differentiation in power wiring applications.

 

4. Main Application
Automotive wiring harnesses, power supply connectors, audio equipment terminals, electrical junction boxes, and battery compartment wiring.

Material

ABS

Material Characteristics

ABS is selected for its excellent impact resistance, rigidity, and superior electrical insulation capabilities. It provides strong structural protection for internal metal terminals while remaining cost-effective for high-volume manufacturing.

Special Requirements

Flame-retardant grades (e.g., UL94 V-0) available for safety-critical electrical applications; custom color matching.

Manufacturing Process

Precision Injection Molding

Production Flow

DFM Analysis → Mold Design → Mold Manufacturing → Injection Molding → Deburring & Inspection → Packaging

Customization Options
