Low Profile “Swing-Lock” Board to Wire Connector for Power

DF57 Series

(Compliant with UL-CSA standards)

Contact Structure

Incorrect Positioning

■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)

2.Header lock improves plug retention

When connecting, the header connector secures the

molded-lance. Play of molded lance is prevented for

added strength. (patented)

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.

5.Solder wicking prevention

The integral molding eliminates any gap between the

terminals and case to prevent solder wicking.

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.

7.Cost effective

Terminals and metal fittings are collectively integrated

into the molding to reduce assembly cost.
