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

DF57 Series (Compliant with UL, C-UL 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.

1.Recommended temperature

proﬁle

The temperature proﬁles are based on the above conditions.

In individual applications the actual temperature may vary,depending on solder paste type, volume/

thickness and board size/thickness. Consult your solder paste and equipment manufacturer for

speciﬁc recommendations.

2.Recommended manual soldering Manual soldering : 350ç ± 10ç for 3 seconds

Recommended screen thickness and

open area ratio (Pattern area ratio)

Thickness : 0.1mm

Open area ratio : 100%

4.Board warpage Maximum of 0.02mm at the connector center, with both ends of the connector as reference points.

5.Cleaning conditions Cleaning is not recommended. When cleaning, please evaluate as if can deteriorate the

performance including mechanical operation and environmental resistance.

6.Precautions

■

When inserting crimp-type (solderless) terminals to crimping (solderless) sockets, to maintain

reliable performance, please do not insert obliquely.

■

DO NOT mate/un-mate non-terminated plugs with non-mounted receptacles.

This may lead to damage or deformation of the contacts.

■Removal of the holding electric cable may cause damage so please be careful.

■

DO NOT apply ﬂux to the contact terminals when hand soldering the receptacle to the board.

Wicking of the ﬂux into the electrical contact areas may lead to connection failures.

■

Slight discoloration on the insulating materials will not affect form, fit or function of the

connectors.

■

Please refer to the documents "DF57 Series Cable assembly Procedure ETAD-H0421", "Crimp

condition" and "DF57-****SCF(A)(**) Crimp quality standards ATAD-H0404" for the cable

assembly procedures.

■

Please refer to the "DF57H Series Mating/Unmating Operation Instruction Manual (ETAD-H0652)"

for the connector operation.
