【 Weak current College 】 AC DC plug of the AC power cord plug and brief】

Major household plug types: single phase two or three pole
AC plug (2)
Main UL plug: 1-15P, 5-15R 15P; 1-, 5-15R
Corresponding to the rated current: 13A, 10A, 15A
Main 3C plug: single-phase poles and three-pole
Corresponding to the rated current: 10A, 16A
Major European plugs: VDE, France, Switzerland, BS-Head
Corresponding to the rated current: 2.5A3A5A13A16A
AC plug (3)
Rated current and UL wire gauge relationships: 18AWG-10A16AWG-13A14AWG-15 while the length of the wire has a clear relationship, usually in the range of 0-50FT, in a variety of commonly used in UL817 's power cord, power extension cords, special-purpose power cable has a specific wire gauge and rated power of control
Rated current and metric wire gauge relationships: 0.75MM and 1.0MM-10A1.5MM-16A
AC plug (4)
AC plug corresponding main safety: UL817/UL498/IEC884/IEC320/VDE0620/BS1363/GB2099
IEC class AC plug main safety performance indicators: anti-shock protection, earthing, anti-aging, anti-harmful to water, moisture, temperature, mechanical strength, heat, breaking capacity, normal operation, the insulation resistance and electric strength, etc.
UL class AC plug main safety performance indicators: conductor connection strength, insulated connection strength, outer preserves testing, SR security testing, swing test, temperature rise Terminal tensile testing, accelerated aging test, insulation resistance and voltage test, over current protection test, etc.
AC plug (5)
Safety performance test requirements: T-type test, sample tests, S-R-routine testing
Where t test for structural and special design performance (such as waterproof, shock protection, Creepage distance and clearance etc.) -----test in General is in product design, or design changes and a longer time period for a confirmation, usually once a year
Where s is the main considerations of product testing of materials and production conditions and the corresponding physical, mechanical strength and electrical properties of test-to-month or week in General or batch, for
AC plug (6)
Where r class test is tailored to each individual product are required to implement the project, mainly to ensure that the manufacturing process of the variation is not on product features and security performance brings risks, mainly contains the electrical performance test

DC plug (1)
At present along no unified national and international standards
The more common standard for Japan of EIAJ
The main distinction between the type of use pursuant to the rated voltage:
3.15V
6.3V
10.5V
13.5V
18.0V
DC plug (2)
Rated current: DC2A
The pressure requirements: AC500V
Insulation resistance £ º100 megohm---DC500V conditions
Other characteristics: contact resistance, breaking capacity, plug power, Terminal strength, flexural strength, flexible strength, salt spray test

DC plug (3)
Different voltage should distinguish categories with copper nail type:

AC power cord (1)
First part: UL class
The main power cable types including: SVT, SJT, ST, SPT-1, SPT-2, SPT-3, XTW wire
Where s indicates that the Service, the power supply cord with cord
V represents Vacuumcleaner
J said Junior
T represents the Thermoplastic PVC materials, including
W indicates Weatherresistance and Waterresistance
AC power cords (2)
Thermoplastic---hot-soluble plastic, PVC, PP, with nylon, PE, PVC is because non-crystalline structure, processing facilities, a wide range of applications and a variety of performance can be improved by adding agent to reach, so the industry use very broad, but it is both in material, flame grilled when asphyxiating fumes.
UL class wire rated voltage 300V, use ST class to 600V
AC power cord (3)
UL power cord conductor primarily through the AWG — Americawiregauge, general household and similar use mainly in 22 ~ 12AWG interval, it indicates that the wire's current load capacity, at the same time it is represented by MIL, pursuant to section and the conductor resistance is measured.
AC power cord (4)
Part II: IEC class
Major wire type: 227IEC52, 227IEC53, HO3VVH2-F, HO5VVH2-F, HO3VV-F, HO5VV-F, HO7RN-F
Of which 227 are IEC publication number-for PVC wire standard 52, 53 refers to its specific designations.
In addition H refers to the European coordination of type
03/05 refers to the voltage rating
AC power cable (5)
VV represent the core of insulation materials and insulation materials outside to PVC, RN in R represents the insulating materials for natural rubber, and N is the outside is a polychloroprene, F represents the wire conductors are soft structure
IEC class wire voltage level of the respective 300V/500V and 750V
> The power cord of the main performance indicators: insulation thickness, aging and tensile strength, elongation, mechanical strength and thermal shock, heat deformation,
