Abstract

The invention discloses a fatigue testing machine for a communication wire. The fatigue testing machine is characterized by comprising an output rod and two rotating mechanisms which have the same angular speeds and move in opposite directions, wherein a driving pin is arranged on each of the two rotating mechanisms and the two driving pins are symmetric about a perpendicular bisector of a connection line of two rotating centers of the two rotating mechanisms; a driving rail by which the two driving pins do reverse reciprocating motion is arranged on the output rod and is parallel to the connection line of the two rotating centers. The fatigue testing machine for the communication wire has the advantages that the two driving pins do reverse reciprocating motion along the driving rail on the output rod; a pair of reverse friction is formed by the two driving pins in the direction of the driving rail, and furthermore, a pair of counter-acting forces is formed on the output rod; the two counter-acting forces are counteracted mutually, so that the working force in the vertical direction between the output rod and a positioning rail is theoretically zero, and the positioning rail does not have torque; and therefore, the friction loss and vibration of the output rod in a reciprocating motion process are effectively reduced.

Description

technical field

[0001] The invention relates to a fatigue testing machine, in particular to a communication line fatigue testing machine. Background technique

[0002] With the rapid development of the economy, the communication industry is advancing rapidly. A series of factors such as the appearance, service life and price of the product comprehensively determine the competitiveness of the product. The built-in data communication lines of notebook computers and mobile phones need repeated bending, while A wire is usually wound by several thin wires, and the outer layer is wrapped with insulating skin. The failure of a single or multiple thin wires inside the communication wire due to high-frequency fatigue damage will have a serious impact on the reliability of signal transmission. Therefore, This type of communication line needs to use a high-frequency fatigue testing machine to perform high-frequency and low-amplitude fatigue life tests to ensure the bending resistance o...
