For medical electronic harness, what are the effects of the quality problems of harness raw materials?

       The quality problem of medical harness raw materials directly affects its insulation performance. Therefore, the selection of raw materials for medical electronic harness is very important. We can not blindly reduce the cost and change the quality of harness materials. In order to prevent quality problems of harness raw materials, we should carefully check the inspection batch number, material certificate and other important information of each batch of materials, and do a good job in the traceability data of material use.

       Brass and bronze are the main copper used for medical harness terminal materials, of which brass accounts for a large proportion. In addition, different coatings can be selected according to needs. The sheath material generally adopts pa6.pa66.abs.pbt.pp, etc. Flame retardant or reinforcing materials can be added to plastics according to the actual situation to achieve the purpose of strengthening or flame retardant, such as adding glass fiber reinforcement, etc.

       The corresponding materials shall be selected as the conductor materials according to different use environments. At present, some medical harness processing enterprises carry out electrical performance test only after product assembly. As a result, they can only be scrapped because the insulation resistance of the insulator itself is unqualified. The reasonable process shall be 100% screening process in the part state of insulating parts to ensure qualified electrical performance.

       The wire harness binding plays the role of wear resistance, flame retardancy, corrosion prevention, interference prevention, noise reduction and beautifying the appearance. Generally, the packaging materials are selected according to the working environment and space. Tape, corrugated pipe, PVC pipe, etc. are generally used for packaging.
