What are the reliability test items of terminal wire?

Principle: Apply a specified voltage between the terminal wire contact piece and the contact piece, and between the contact piece and the shell for a specified time, and observe whether the sample has breakdown or discharge.

(5) Terminal line contact resistance test

Purpose: To verify the resistance value that occurs when current flows through the contact surfaces of the contacts.

Principle: By passing a specified current to the terminal line, measuring the voltage drop across the terminal line to obtain the resistance value.

(6) Terminal wire vibration test

Purpose: To verify the effect of vibration on the performance of the terminal wire and its components.

Vibration type: random vibration, sinusoidal vibration.

(7) Mechanical impact test of terminal wire

Purpose: To verify the impact resistance of the terminal wire and its components or to assess the firmness of its structure.

Test waveform: half sine wave, square wave.

(8) Thermal shock test of terminal wire

Objective: To evaluate the influence of terminal wire on its functional quality under the rapid and large temperature difference change.

(9) Combination cycle test of terminal line temperature and humidity

Objective: To evaluate the influence of the terminal wire on the performance of the terminal wire after being stored in a high temperature and high humidity environment.

(10) High temperature test of terminal wire

Purpose: To evaluate whether the performance of terminals and insulators changes after the terminal wire is exposed to high temperature environment for a specified time.

(11) Terminal wire salt spray test

Purpose: To evaluate the resistance to salt spray corrosion of terminal wires, terminals, and coatings.

(12) Mixed gas corrosion test of terminal line

Objective: To evaluate the corrosion resistance of terminal wires exposed to mixed gases of different concentrations and the effect on their performance.

(13) Terminal wire swing test
