The Yongxiang 12034363 is a precision-engineered Terminal Position Assurance (TPA) secondary lock, specifically designed for the Metri-Pack 630 Series automotive connectors. In high-power and heavy-duty electrical systems, terminal stability is critical. This TPA lock acts as a secondary mechanical safeguard, ensuring that terminals are fully seated and preventing them from backing out under intense vibration or mechanical stress. It is a vital component for maintaining the safety and longevity of powertrain and engine compartment wire harnesses.

Key Performance Advantages
Superior Environmental Shielding
The BOX-L1 series creates a robust barrier against environmental contaminants such as fine dust, grit, and industrial impurities. This is essential for protecting precision components from "fouling" which can lead to equipment failure.
01
High Thermal & Chemical Stability
Constructed from premium heat-stabilized materials, these caps maintain their structural integrity in high-temperature engine compartments. They are engineered to resist degradation from common automotive fluids, including oils, fuels, and hydraulic cleaners.
02
Effective Sealing & Vibration Damping
The design incorporates a precise interference fit that provides a hermetic-like seal, preventing moisture ingress (wash-water or humidity). Additionally, the material properties offer a degree of shock absorption, protecting the connector interface from mechanical impact and resonance.
03
Prevention of Material Contamination
In industrial and logistics applications, these caps prevent raw materials or foreign objects from entering open connector ports during storage or transport, ensuring the equipment is "ready-to-use" upon arrival.
04
Primary Application Fields
The BOX-L1 Series is a versatile protective solution across multiple sectors:
Automotive Systems
Protecting unused or disconnected harness ports in the engine bay, chassis, and exterior lighting systems.
Precision Industrial Machinery
Shielding control panel interfaces and sensor ports on factory floor equipment and CNC machinery.
Logistics & Transport
Safeguarding electrical connections on shipping containers, trailers, and heavy-duty transport vehicles during transit.
Outdoor Infrastructure
Protecting power and signal interfaces for telecommunications and renewable energy systems exposed to the elements.
Quality Assurance & Professional Standards
As a global B2B supplier, Yueqing Yongxiang Electronics prioritizes reliability:
Rigorous Material Testing
Every batch of material is tested for tensile strength and thermal aging to ensure the caps do not become brittle over time.
Precision Fit Validation
We conduct 100% fit-testing on critical dimensions to ensure the caps provide a secure, "snap-on" seal that stays in place even under vibration.
Certified Manufacturing
Our production processes are managed under the ISO/TS 16949 quality framework, meeting the high standards of global industrial and automotive supply chains.
B2B Supply & Logistics
Standard Export Packaging
Products are packed in moisture-proof PE bags and high-strength reinforced cartons to ensure safe delivery to global ports.
OEM/ODM Service
We offer custom-sized protective caps and material modifications (including UV-stabilized or V0 flame-retardant versions) based on your specific requirements.
Sampling Program
Technical samples are available for engineering evaluation and environmental testing.
Lead Time
Efficient manufacturing cycles with standard shipping within 7–15 days for bulk orders.
