Abstract

The invention relates to a circuit converting device, in particular to a shield wiring base. The shield wiring base aims to reduce or eliminate the adverse effect on the frequency characteristic of an alternating-current resistor from inductance and capacitance guided by the wiring base to the greatest extent, and improve use power of the alternating-current resistor. The shield wiring base mainly comprises the wiring base upper end, the wiring base lower end and a conducting rod, wherein the wiring base upper end is composed of an upper end metal ring and a polyoxymethylene material, the wiring base lower end is composed of a lower end metal ring and a polysulfone material, and the conducting rod penetrates through the wiring base upper end and the wiring base lower end, so that the upper portion of the conducting rod extends out of the wiring base upper end and the lower portion of the conducting rod extends out of the wiring base lower end. The shield wiring base is applied to alternating-current products, high-value direct-current resistance products and instruments with voltage less than 2kV, is wide in application range, improves the safety performance of electric appliances, and has good economic value and environmental protection value.

Description

technical field

[0001] The invention relates to a circuit conversion device, in particular to a shielded terminal block. Background technique

[0002] AC resistor products in electrical instruments and meters mainly include AC standard resistors, shunts, AC resistance boxes and impedance bridges for measurement. Since AC resistors are mostly used under AC conditions, they will be affected by factors such as distributed capacitance, distributed inductance, skin effect, and eddy current effect. In addition, the main technical feature of AC resistors is the addition of AC parameters to the technical specifications of DC resistors. Based on the above reasons, the accurate measurement of AC resistors has always been a difficult problem. At present, my country has not yet established a national standard for AC resistors. To ensure the accuracy and reliability of AC resistors during testing and use, it is necessary to improve the frequency characteristics of AC resistors and redu...
