Regarding insulation protection, ordinary insulating sleeves offer limited protection and are ill-suited for complex environments. Furthermore, existing structures lack effective buffering measures, making the copper conductor and insulating sleeve susceptible to damage during equipment vibration or external impacts, thus affecting service life.

Nickel sheets 20 are welded to the upper and lower surfaces of the mounting parts.
