Description

TECHNICAL FIELD

[0001] The utility model relates to signal detection line technical field, specifically a kind of high-strength tensile detection signal with line. BACKGROUND

[0002] In some small-specification detection line, the required current signal is not high, but in the application scene, higher tensile strength of wire rod is required to meet the application.

[0003] When the copper conductor is small in size, the commonly used copper conductor wire rod can withstand less than 10N of tension, and when the wire rod is subjected to a larger external force such as 100N or more tension, it is easy to break and affect the normal use of the wire rod. High-strength steel wire is too hard and is not suitable for the softness requirement in the application scene of small-specification wire rod. If copper conductor and aramid fiber are mixed, the wire rod terminal interface is a conductor, and the fixing position of aramid fiber needs to be specially designed, which increases the design and processing difficulty of the terminal.
