Substrate Twin (Pair) Cable Swing-Lock Connector for Low-Profile Power Source
DF57 Series
Swing-Lock Structure explanatory drawing

Features
1.Reinforced lock structure with swing lock
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)
When connecting, the header connector secures the
molded-lance. Play of molded lance is prevented for added
strength.
After mating
Contact Structure
Two point contact terminals
Effective mating length
0.42mm
3.Highly reliable contact structure
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.

4.Solder wicking prevention
The integral molding eliminates any gap between the
terminals and case to prevent solder wicking.
5.Case disengagement prevention
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.
6.Cost countermeasure
Terminals and metal fittings are collectively integrated into the
molding to reduce assembly cost.
