Zebra Strip Connector
The zebra elastomeric connectors is a kind of conductive connector with good elasticity, which has excellent electrical properties and is widely used in the field of electronic products.
As electronic and electrical equipment becomes thinner and more miniaturized, users have higher and higher functions of products, so it is necessary to fully consider product reliability in the early stage of product design.
This guide contains various technical parameters, electrical characteristics, structural characteristics, design specifications and other information of elastomeric connectors, to help users select and formulate more reliable conductive rubber connectors and structural parameters in the early stage of design.

YCD type conductive rubber connectors are supported by insulating silicone rubber on both sides of the fully conductive layer, which can meet applications with demanding insulation requirements. At the same time, because the insulation layer is softer than the fully conductive layer, good contact performance can be achieved in practical applications with only a small compressive force.

Elastomeric Connectors Specification
The regular size of the middle conductor is determined by the width of the conductive strip
Elastomeric Connectors Dimension Design Principle
(L):The length of the glass is reduced by 0.5mm
(H):9% to 15% of the height of compression ratio, the best compression ratio of 10%.
(W):Edge width of LCD*(0.90~0.95).
(P):The ratio of the width of each golden finger to the adhesive strip of PCB≥3~5.
In the formulation of elastomeric connectors size, in order to ensure the best connection performance and reliability , it should follow the data and specifications on the two tables and design principles , fully consider the impact of tolerance.
Elastomeric connectors height and width ratio should be greater than or equal to 1.5.
The elastomeric connectors is limited by the manfacturing craft and the comductive lines can not be completely vertical, to the conductive lines of the conductive rubber connector which is less than 2 degrees are allowed to be skewed.
Elastomeric Connectors Mechanical Property Requirements
