By What is strain relief test?
The Strain Relief Test is conducted on products that have an electrical cord or cable permanently attached to the product. Test Purpose: The purpose of the test is to confirm that normal stresses applied to cords or cables is not transmitted to the internal electrical connections.
How to test a cable strain relief?
Strain relief The drilling hole is in a horizontally mounted plate and fixes the sample for the test. A specified weight is applied to the lower end of the cable. During a testing time of 1 minute the cable has to withstand the tensile load and the cable may not slip out of the cordset’s overmolded head.
What is wire strain relief?
A strain relief is used to provide a transition from flexible cable to a rigid connector or connection point. Cables that pass through an opening into a device typically employ a grommet to anchor the cable to the device and provide protection against damage from an axially applied load.
What is cord anchorage?
IEC 60884-1 is the international standard for plugs and sockets. The plug is subjected to 100 pulls of 60N on the cord every 1 second. This test is followed by the torque test.
How tight should strain relief?
The strain relief should have a tight fit with the dryer cabinet and be in a horizontal position. Do not further tighten strain relief screws at this point.
Is a strain relief necessary?
Why is a strain relief clamp necessary for the cord connection to some electric appliances? When a power cord is connected to terminals inside the appliance, the point where the cord penetrates the shell of the appliance needs to have a strain relief clamp, also sometimes called a cord connector, as a securing device.
How do you start a strain relief?
If it’s the typical two piece type, try squeezing the two parts together with small channel locks or pliers while pulling out at the same time. Another method is to insert a small flat blade screwdriver under the smaller part, pry up and pull out at the same time.
What is extension cord strain relief?
The strain relief is typically a series of ridges at the point where the cabling meets the connector or plug that allows flexibility in the cable without putting stress on that vulnerable point in the cord.
What is strain relief?
Strain Relief. Definition – What does Strain Relief mean? A strain relief is a standard fixture for electrical cables that functions as a feature for relieving the stress from the cable connections themselves to prevent them from breaking.
What is strain relief in electrical wiring?
A strain relief is a standard fixture for electrical cables that functions as a feature for relieving the stress from the cable connections themselves to prevent them from breaking. It is located in the base of the connector where the connector meets the cable and usually comes pre-molded as part of the connector itself.
