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 (patented)

Contact Structure
Two point contact terminals
2.Header Lock Improves Plug Retention
When connecting, the header connector secures the molded-
lance. Play of molded lance is prevented for added strength.

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.Insert guide key prevents misalignment
Insert guide key guides the crimp socket to the correct mating
position and prevents misalignment, which improves mating
operation and prevents possible connector breakage with
incorrect mating.

Positive Lock
5.Solder wicking prevention
The integral molding eliminates any gap between the
terminals and case to prevent solder wicking.
Insert guide key touches to
the header prior to the
positive lock, which guides
the socket to the correct
mating position.
6.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.
Starts mating after the socket is aligned to
the correct position
7.Cost countermeasure
Terminals and metal fittings are collectively integrated into the
molding to reduce assembly cost.
