Mechanical Reliability (Compressive) Test Apparatus

A mechanical test apparatus (cable compression) for various types of flat cables (for example, ribbon cables) is disclosed. This test apparatus will provide the necessary mechanism required for testing flat cables. The mechanical stress durability (compression) of the cable can be verified using this test apparatus.

Some high performance signal transmission cables are designed to transmit and receive electrical signals with a highly flexible (mechanically durable for multiple bending) body. These cables should be able to perform under confined space in servers and workstations, just to name a few. Their slim design minimizes obstructions to the limited space which in turn allow maximum air flow in the system.

Having to work in confined space also means that a highly durable and flexible cable is required for the various applications. The mechanical performance of a cable is an important criteria in the product specification. As such, a series of product durability tests are defined to verify the design and construction of such a cable.

With the desired usage of a cable in highly demanding applications in the network communication industries, its environmental, mechanical and electrical reliability may be a concern.

Mechanical functional performance of a cable is very important in all applications due to its highly flexible and mechanically durable design. Often, cables will be used in environments whereby bending and compressing them is a common practice.

A mechanical stress test, defined as the Cable Compressive Test, is designed for these flat cables. This test will be a good measurement and evaluation tool / method for the cable when it is under mechanical stress such as during the cable winding and packaging at its manufacturing process and also during its applications, such as in a server whereby a drawer type hard disk drive (HDD) is used.
