Abstract

The invention provides a signal acquisition isolator, comprising a front terminal plate, a rear terminal plate, a connecting plate and eight groups of voltage-reducing circuits, wherein the front terminal plate and the rear terminal plate are arranged correspondingly; the front terminal plate is provided with inserting needles and hexagonal positioning screws; the rear terminal plate is provided with wire spring installing holes, inserting needle jacks and hexagonal positioning screw jacks; the two sides of the connecting plate are respectively and symmetrically provided with the eight grooves, each pair of grooves is respectively and internally provided with a voltage-reducing circuit; the voltage-reducing circuit consists of two same voltage-reducing branch circuits; each voltage-reducing branch circuit comprises a voltage-reducing resistor and a fuse which are connected in series; pins of the voltage-reducing resistors are welded on the inserting needle jacks which are communicated with the wire spring installing holes; and pins of the fuses are welded on the tail parts of the inserting needles. The signal acquisition isolator has the advantages of scientific design, simple structure, strong practicability and effective protection of acquisition equipment.

Description

technical field [0001] The invention relates to a signal acquisition and protection device, in particular to a signal acquisition isolator. Background technique [0002] At present, during the operation of railway signal monitoring products, a large number of collected signals are required, but some signals have high voltages, up to 3000V. In the process of collecting signals, the signal collecting equipment is easy to be damaged due to these excessive voltages, thereby affecting the working efficiency. At the same time, it is very difficult to improve the withstand voltage capability of PCB circuit boards, and there are potential safety hazards. Therefore, a device capable of reducing the signal voltage is needed. In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, thereby providing a signal acquisition...
