Technical FAQs
Q: How to insert crimped contacts into the connector housing?
A: Before inserting crimped contacts, orient both the connector housing assembly and contacts for proper mating. Position the housing with its locking feature facing upward, and align the contact so that its barrel‑seam side also faces upward.
Do NOT rotate the contact during or after insertion; rotation may cause damage to the rubber seal or crack the housing.
⒈In case of receptacle contact
Step①: Tilt the crimped contact. Rest its tip on the seal‑equipped mating cavity. Expand the seal opening carefully to avoid damaging the cavity top surface. Press the contact tip onto the rubber seal plate to insert the box section of the contact.
Step②: Straighten the crimped contact, then insert the tip of its box section. Push the contact all the way in — do not pry or apply undue force — until you hear a click.
Step③: After hearing an audible‑click upon full contact insertion, gently pull the wire to confirm the contact is securely locked by the housing lance.
⒉In case of tab contact
Step①: Insert the crimped contact straight into the housing. Avoid damaging the periphery of the seal‑fitted cavity with the contact tip. Tilting the contact toward the housing locking side during insertion may cut the rubber seal plate and cause the contact tip to enter a neighboring cavity. Refer to the figure below; pay close attention to insertion orientation.
Step②: Push the crimped contact all the way in. Do not pry or apply excessive force, stop when you hear an audible click.
Step③: After hearing an audible click upon full insertion, gently pull the wire to confirm the crimped contact is securely locked by the housing lance.
Q: How to remove crimped contacts from the housing after incorrect insertion
A: If a crimped contact is inserted into the wrong cavity, removal shall only be performed by qualified personnel. Do not reuse the housing or rubber seal plate once they have been used.
Insert the extraction tool between the crimped contact and housing from the mating side. Push the tool in direction ① to disengage the housing lance from the contact locking hook. Then pull the wire in direction ② to remove the contact from the housing.
Q: What is the correct procedure for mating the male and female housings of this waterproof connector?
Step①: Align the locking tab on the male housing with the locking lever of the receptacle housing, as illustrated in the figure below. Perform mating along the mating axis; do not pry.
Step②: Mate the two housings until the lock is fully engaged. Verify secure housing locking by gently pulling the housing. (An audible click will be heard when the locking lever and locking tab are properly engaged.)
