FUJIPOLY ZEBRA¢ç connectors have alternating layers of conductive carbon-filled and non-conductive silicone rubber.  They make reliable connections by being deflected between contacting surfaces.  ZEBRA connectors are used for connecting any LCD from small displays for watches to large area displays for instruments.  Table A shows the different types of ZEBRA connectors available.  Table C shows performance characteristics.

 

 Zebra Low Temperature Length/Pitch

The diagram above shows the three dimensions of the ZEBRA connector.  When ordering, the three dimensions should be specified within the limits shown in table B.

For best overall performance, ZEBRA connectors must be ordered and used with a ratio of H/W equal to or greater than 1.5.

NOMINAL RESISTANCE CALCULATION

To calculate the resistance of the ZEBRA connector use the following formulas:

Where:    
      Cw = Contact pad width in inches
      H = ZEBRA connector height in inches
      W = ZEBRA connector width in inches

METRIC:
             60 x H
      R = ---------
             Ew x W

INCHES:
             2.37 x H
      R = -----------
              Ew x W

Where:   
      R = Resistance(§Ù) 
      Ew = Electrode Pad width (mm or inches)
      W = Connector width (mm or inches)
      H = Connector height (mm or inches)


 
NOMINAL FORCE DEFLECTION

ZEBRA connectors should be deflected 5% to 25% of H. To calculate F-Force for deflection, use the following formula:

Where:    

      F = Force(N)

            H-H1 x 100% (Deflection in %)
      D= -------
              H

      H   = Height of connector (mm or inches)
      H1 = Deflected height of connector (mm or inches)
      W  = Width of connector (mm or inches)
      W1 =  Width of ZEBRA portion (mm or inches)
      L   = Length of connector (mm or inches)


Plain ZEBRA or Insulation Barrier Type

Metric:
      F(N) = 9 x D x W x L x 9.8 x 10-3

Inches:
      F(N) = 5806 x D x W x L x 9.8 x 10-3


Silicone Support Type:

Metric:
      F(N) = [(9D x W x L) + {1.8 x D x (W-W1) x L}] x 9.8 x 10-3


Inches:
      F(N) = [(5806D x W x L) + {1161 x D x (W-W1) x L}] x 9.8 x 10-3
