Embodiment 1

[0016] Embodiment one: see Figure 1 ~ Figure 3 , the isolator inspection device of the present invention includes an insulating seat 1 and an insulating cap 2, the lower end of the insulating seat 1 is matched with the insulating cap 2, and the upper end of the insulating seat 1 is designed as a stepped groove matching the end face of the isolator terminal block. The step groove on the seat 1 and the corresponding position of the terminal of the isolator 5 are provided with a corresponding number of positioning wire holes through the insulating seat 1, and a set of elastic probe systems are respectively installed in the positioning wire holes. The probe 10 of the elastic probe system protrudes from the stepped surface of the upper end of the insulating base 1, and connects with the conductor sleeve 7 to lead out the wires connected to the power supply and the inspection instrument respectively.

Embodiment 2

[0017] Embodiment two: see Figure 1 ~ Figure 3 The difference between the isolator testing device of this embodiment and the first embodiment is that a structure of the elastic probe system is further disclosed. The elastic probe system includes a conductor sleeve 7, a probe 10, a pressure cap 8 and a spring 9, the probe 10, spring 9 and pressure cap 8 are sequentially installed in the conductor sleeve, and the conductor sleeve 7 is matched and mounted on the insulating base 1 The elastic probe system is installed on the insulating base through the conductor sleeve in the positioning wire hole on the upper part.

Embodiment 3

[0018] Embodiment three: see Figure 1 ~ Figure 3 , the isolator inspection device of this embodiment, its structure is suitable for the inspection of isolators for eight terminal blocks. There are two steps and eight positioning wire holes on the insulating base 1. The two steps are opened inside the insulating base, which is symmetrical to the left and right. There are eight positioning screw holes and a fixed screw hole connected by bolt 3 on the upper end surface of the insulating base. The eight positioning wire holes have four at one end, symmetrical left and right, and eight copper sleeves are installed with threads in the wire holes, of which four long copper sleeves 7, four short pain sleeves 6, and four long copper sleeves 7 are symmetrically distributed on the outside. Four short copper sleeves 6 are symmetrically distributed on the inner side, and a set of elastic probe systems are installed in each of the copper sleeves. The probe system consists of probes 10, pre...

Abstract

The invention relates to an inspection device of electric devices, in particular to an inspection device of an isolator. The inspection device comprises an insulation base (1) and an insulation cap (2), wherein the lower end of the insulation base is connected with the insulation cap in matching mode, a step groove matched with the end surface of a wiring base of the isolator is arranged at the upper end of the insulation base, positioning screw holes with the corresponding quantity as wiring terminals of the isolator and penetrating through the insulation base are arranged on the step groove at the positions corresponding to the wiring terminals of the isolator, an elastic probe system is respectively arranged in each positioning screw hole, probes of the elastic probe system extend out from the step surface disposed at the upper end of the insulation base, and a conductor sleeve is respectively connected with a lead which is respectively led out from a connection power supply and an inspection instrument. The inspection device of the isolator is mainly used for inspection of the isolator, limits the isolator by aid of a step arranged in the insulation base and the special shape, can ensure that the probes and the wiring terminals are effectively contacted, greatly improves safety and inspection efficiency, and is reasonable in design, simple in structure, convenient to use and good in popularization and use values.

Description

technical field [0001] The invention relates to an electrical equipment inspection device, in particular to an isolator inspection device, which is mainly used for the inspection of isolators. Background technique [0002] The signal isolator is used to adjust and isolate various signals of field instruments, and convert them into standard signals acceptable to computers, DCS, PLC, etc. or special signals specified by users. The input, output and power supply of the isolator are fully isolated, with strong anti-interference ability, high precision, high cost performance, very reliable and stable work, and can be used in conjunction with unit combination instruments and DCS, PLC and other systems. It is widely used in major projects in manufacturing, electric power, metallurgy and other industries. [0003] For the safety of control, the quality of the signal isolator is very important for the realization of automatic control. Therefore, verification of signal isolators is ...
