1.Reinforced lock structure with swing lock
3. Highly reliable contact structure
4. Solder wicking prevention
5. Case disengagement prevention
6. Cost countermeasure
Features
A swing-lock structure, featuring our own unique connection
method, reinforces the lock structure of the electric cable
side, with a structure resistant to tough electric cable routing
and disengagement of cables under load.
In addition, the connection surface has a guide insertion to
facilitate insertability (patent pending)
molded-lance. Play of molded lance is prevented for added
strength.
Despite the low-profile design, with a stacking height of
1.4mm, an effective mating length of 0.42mm is achieved. The
structure features two-point contact terminal geometry with
high contact reliability.
The integral molding eliminates any gap between the
terminals and case to prevent solder wicking.
Reinforcing hardware (metal fittings) are integrated in the
molding, which help prevent the case from disengaging with
the terminals due to tough electric cable routing and load.
Terminals and metal fittings are collectively integrated into the
molding to reduce assembly cost.
When connecting, the header connector secures the
