IEC60335 Household Appliances Cable Flexing And Swivel Connection
Rotation Test Equipment
Product information:
The power cord flexibility test equipment is designed and
manufactured according to standard requirements of IEC 60335-1
clause 25.14 figure8, IEC 60335-2-23 clause 23.3 flexing test for
conductors that are flexed when stored and clause 11.101 swivel
connection sliding contacts temperature rise test. It is used to
check that the supply cord of the small household appliances (Such
as coffee pot / electric iron) and similar appliances is adequately
protected against excessive flexing where it enters the appliance.
The test principle is to fix one end of the sample, and the other
end to drive the sample to rotate through the motor. At the same
time, apply the load with the rated current of 1.25 times rated
voltage to the sample, hang up a 1N weight on the flexible cord of
the sample to rotate the electrified sample at a certain speed. The
turntable rotates 20 turns in the forward direction and then 20
turns in the reverse direction at a speed of 50 r/min, and
automatically stops when the number of tests is reached, and the
temperature rise of the slider is measured at the same time.
This equipment adopts floor-standing structure. By PLC control and
touch screen operation, the test times, test rate and bending angle
can be pre-set, and the built-in 5kW load output is suitable for
most hair curlers, hair irons and household appliances test
requirements.

Structure
Maintenance
Before testing, please check the components of the fixture is loose
or not.
Before testing, please check whether the load socket is damaged or
not.
Before testing, please check whether the manipulator swivel smooth
by operate the manually speed.
Under non-work state, please take off the test samples and weights,
turn off the load power supply and external power supply.
Please do not place any heavy and sharp objects on the equipment.
Please do not thrust the machine components, in order to avoid
position offsetting.
Please keep away from liquid, in order to avoid electrical circuit
short.
Special function
【Single/Double sieded】selected button: Operator can select one side
which is with 0° as the center line to do reciprocating flexing
(Single-Sided swivel) in this system, and the reciprocating swing
range will not exceed the center line. Operator can also select
each half flexing angle of the left and right direction around the
center line at 0°, that is, flex around the center line
(reciprocating) (Double -Sided swivel). The default is double-sided
flexing. Press the button for single-sided swivel. This button can
be used in conjunction with the [Left and Right Swivel] button to
select the direction and single-side and double-side swivel at the
same time. Special note: Before switching of these buttons,
operator must make sure that the turntable is at the starting
position by pressing [Homing] button, and the counts are cleared by
pressing [Count Cleared] button, then the switching of these
buttons will be effective. The purpose is to avoid changing the
direction of rotation while one direction is being tested.
