Technical FAQs
Q: What is the recommended wire strip length?
A: Reference value for wire strip length is 3.00±0.20mm.
The wire strip length depends on wire type and crimping method, and actual processing conditions shall be used to confirm the optimal strip length.
Do not nick or cut wire conductors during wire‑stripping operation.
Q: How to insert crimped terminal into housing correctly?
A: Before inserting the crimped terminal, align the orientation of housing and terminal for proper mating.
When the lock opening of the housing faces upward, the barrel‑seam side of the crimped terminal shall also face upward.
Do not rotate the terminal during or after insertion. Rotation may cause damage to rubber seals and housing.
Note: For terminal insertion: keep the smooth surface upward, anti‑key feature downward, and terminal barrel seam upward. Incorrect orientation will cause housing damage.
Q：What is the wiring recommendation for harness exiting from the connector?
A：Avoid sharp 90‑degree bends immediately at the connector wire exit. Sharp right‑angle bending will shorten harness service life and may lead to functional failures. Gradual, gentle cable bending is recommended during routing design.
Q：What should be noted during finished‑product inspection of harness assemblies?
A：
1. Use precision fixtures during wire inspection and electrical continuity testing to avoid prying the connector.
2. Perform continuity tests using the mating counterpart connector (e.g. receptacle for tab contact). Do not use non‑matching test
pins. Replace test mating connectors periodically.
3. Replace any deformed or damaged connectors, contacts, sealing rings or wire seals with new parts directly, regardless of damage severity. Do not attempt repairs.
4. Verify wire seals are properly seated inside the housing.
5. Do not perform air‑blow testing, as this may dislodge sealing components.
Q：What are the storage and transportation precautions for connectors and harnesses?
A：
1. Store housings and crimped contacts under conditions: temperature 25 °C ± 5 °C, relative humidity ≤70% RH. Keep away from
direct sunlight, moisture and dust. Sealing rings and wire seals are rubber‑based components. UV exposure will cause rubber aging, and dust contamination will degrade waterproof performance.
2. Handle stacked housings and wire harnesses with extra care during storage and transportation.
Q: How to properly mate the male and female waterproof connectors?
A:
⒈Align the lock catch of female connector with lock lever of male connector, mate along the mating axis, do not pry.
⒉Push the two housings together until both‑side locks are fully engaged. Two distinct “click” sounds will be heard once locked in
place.
⒊Gently pull the connector housing to verify secure locking before putting into service.
Q: How to properly unmate this latch‑lock waterproof connector?
A:
⒈Press down the locking lever to release the inter‑lock.
⒉Pull male and female housings apart in opposite directions.
Important: Do NOT pull by wires directly, always grip the connector housing for disconnection.
