YP type Zebra Connectors are supported by a sponge foamed insulating silicone layer on both sides of the zebra layer to meet more applications where insulation is critical. At the same time, the foam layer is very soft, so in practical applications only a small compressive force is required to achieve good contact performance.
To ensure that zebra connectors are made correctly, the naming specifications are as follows:
The superior elasticity of conductive rubber connectors can effectively avoid the risk of good contact with components due to aging deformation and accidental drop of structural parts during the use of electronic equipment, but with the deformation of structural parts and the change of compression force, the compression ratio and resistance of conductive rubber connectors will also change, and it is necessary to fully consider when setting structural parts and conductive rubber connectors. As follows:
Spline: YP P0.1 10×5×2.5mm CW0.8
Relationship between compressive force and compression ratio
Resistance vs. compression ratio
R = Resistance value (Ω)
CW = Conductive width (mm)
L = Conductive length (mm)
H = Conductive height (mm)
ρ = volume resistivity (Ω·cm)
The testing process should be maintained > 10% compression ratio to obtain accurate test results.
F = Press pressure (g)
D = Compression ratio D = (H-H1) ÷ H
E0 = Zebra layer modulus of elasticity 3.5MPa
E1 = Modulus of elasticity of the insulation liner 1.7MPa
H = Conductive rubber connector height (mm)
W = Conductive rubber connector width (mm)
CW = Zebra Layer Width (mm)
W1 = Insulation liner width (mm) W2 = W-W1
L = Conductive rubber connector length (mm)
Implementation standard: GB2439, GB/T528
