The main data sheet of Terminal Strip 

 

Main technical parameters of Feed-through Terminal block:       

(1)Outshape:

Processing of sound and drawings of the parts fit, molding no flash, scratches, defects such as miniature

(2) Dimension: 

According to Drawing requirement

(3) Insulation resistance:

DC500V megger test by Road and Road between:> MΩ charged between sites and easy access to parts> MΩ

(4) Withstanding Voltage: 

Test voltage: Road and Road between the site and easy to live between the contact area AC2500V (rated voltage less than 300V,  the test voltage of 2000V), frequency 50HZ, 1 minute without breakdown, flicker,

(5) Cable retention: 

The regular insertion of the corresponding nominal connection capacity of the connection, plug-type terminals for 187 each root should be able to withstand force of 78 N over the role of screw fastening type 80N above; pluggable terminals for each root of 250 force should be able to withstand more than the role of 80N, screw-type fastening more than 80 N

(6) Moisture Resistance :

1. Insulation resistance: before the test ≥ 100MΩ; test ≥ 100MΩ

2. Pressure: baseline: AC2500V/min; test: AC2500V/min (When rated voltage less than 300V, in order to 2000V)

3. Contact resistance : Before the test, ≤ 3mΩ; test ≤ 6mΩ, no insulation damage, no abnormal appearance

(7) Temperature and flame resistance: 

PBT (G = 20% -30%) and phenolic resin (Bakelite): 180 ℃ ± 3 ℃ for 2 hours, without exception, PC temperature resistance: 180 ℃ ± 3 ℃ for 2 hours, no abnormal , PBT, Bakelite, and PC Flammability: UL94-V0

(8) Strength test:

Products fell 6 sides were all from a height of 30cm drop to a natural wood surface, strength and the thickness 20mm, look no deformation, fracture phenomenon.

(9) Contact resistance

Between the contacts and contact resistance measurement regulations ≤ 3mΩ, durability test ≤ 6mΩ.

(10) Logo:

Should the main body of the terminal block has the following permanent signs: 

a. Rated Voltage (V)   b. Rated current (A) c. Type d. trademarks or factory name

(11) Glow wire test:

Test, although there should be no flame or fire but in the 30s after the removal of the hot wire off

(12) Conductive Metal:

with high conductivity of the brass, phosphor bronze, high elastic, nickel-plated surface to be handled. To steel or copper alloy as the raw material, nickel-plated surface to be handled. Conductive parts of the surface anti-corrosion protection layer should be smooth , no glitches, no rust and other defects.

(13) Terminal strength:

In the terminal wing to keep the tension increases 150N 1min, terminal on the wing can not unplug from the matrix

(14) PTI:  Terminal blocks insulated base material should be resistant to tracking, anti-tracking index PTI175

(15) Temperature rise:  According to the rated current of power tests, the maximum temperature in the 30K the following

(16) Heat resistance:

1. Ball pressure test: ball indentation diameter <2mm

2. Insulation resistance: Before the test, ≥ 100MΩ; test ≥ 100MΩ

3. Pressure: Before the test, AC2500V/min; test AC2500V/min (as rated voltage less than 300V, in order to 2000V)

4. Contact resistance: Before the test, ≤ 3mΩ; test ≤ 6mΩ

5. without insulation damage, no abnormal appearance

(17) Cold Resistance:

1. Insulation resistance: Before the test, ≥ 100MΩ; test ≥ 100MΩ

2. Pressure: Before the test, AC2500V/min; test AC2500V/min (When rated voltage less than 300V, in order to 2000V)

3. Contact Resistance: Test former ≤ 3mΩ; test ≤ 6mΩ
