Product Details
| Terminal Security & Integrity | Material Resilience & Standards | Quality Control & Inspection Efficiency |
| Secondary Double Lock Mechanism | Engineered as a Terminal Position Assurance (TPA) component that mechanically prevents terminals from backing out. | Maximum Circuit Reliability: Ensures 100% terminal seating, eliminating intermittent signal failures caused by vehicle vibration or harness pulling. |
| Automotive-Grade PBT Construction | Manufactured from glass-filled PBT, providing excellent resistance to heat, engine fluids, and chemical exposure. | Harsh Environment Performance: Maintains structural integrity under hood or chassis temperatures (-30°C to 105°C), ensuring the connector’s long-term safety. |
| High-Visibility Yellow Identification | The bright yellow color provides a sharp visual contrast against the black connector housing. | Visual Error-Proofing: Allows assembly line workers and QC inspectors to verify at a glance that the secondary lock is fully engaged, reducing assembly defects. |
| Precision Press-Fit Design | Specifically contoured for the Econoseal J Mark II+ 8-way cap housing, ensuring a snap-in fit without extra tools. | Simplified Assembly: Streamlines the harness manufacturing process by providing a clear tactile and audible “click” once the plate is securely seated. |

Q1: Can the 174985-7 be used with other connector series?
A: This double lock plate is specifically designed for the TE Econoseal J (Mark II+) series 8-position cap housings. It is not universal and must be matched with its corresponding housing to ensure the TPA function works correctly.
Q2: What is the primary purpose of the yellow color on this part?
A: Beyond series identification, the yellow color serves as a “Poka-Yoke” (error-proofing) feature. Since most Econoseal housings are black, the yellow plate makes it extremely easy for inspectors to see if the secondary lock is missing or not fully pushed in.
Q3: Is this lock plate reusable if I need to de-pin the connector?
A: Yes, the 174985-7 is serviceable. You can carefully pry the plate back to its pre-staged position using a small pick tool to release the terminals, then press it back into place after re-insertion.
