The invention provides a voltage divider standard assembly capable of telescopic adjustment, and aims at solving the problem that hard connection between resistor and capacitor elements has higher requirements for the processing precision of the resistor and capacitor elements. The voltage divider standard assembly comprises at least two conductors arranged separately, resistor and capacitor elements are arranged between two adjacent conductors, at least one end of at least one of the resistor and capacitor elements is connected with the corresponding conductor via an sleeve electrical connection structure, and the conductor and the corresponding elements connected via the sleeve electrical connection structure can be guided to move relatively via a guiding structure. The conductor and the corresponding elements connected via the sleeve electrical connection structure are in guiding cooperation via the guiding structure, the plugging direction of two conductive structure in sleeve cooperation in the sleeve electrical connection structure is more accurate in the plugging process, and the plugging direction is ensured.
