Example Embodiment

[0020] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0021] An AC analog input plug structure for a protective device in the laboratory, such as figure 2 As shown, it includes a long-tail clip-type bracket and a set of AC analog input plugs 7. The long-tail clip-type bracket includes a bracket plate 6, clamp arms 5 on both sides and clamp arm pressure rings 9, which are arranged at intervals on both sides of the clamp arms. AC analog input plug, the AC analog input plug is a Y-shaped plug, and the Y-shaped plug is provided with a connection hole 8 . The Y-shaped plug is integrally formed with the clamp arms on both sides of the long-tail clip, and each Y-shaped plug is used as a supporting contact of the AC analog signal input connector, and the Y-shaped plug is connected to the signal circui...

Abstract

The invention relates to a protection device AC (alternating-current) analog quantity input plug for a laboratory, and the plug comprises a binder clip type support and a group of AC analog quantity input plugs, the binder clip type support comprises a support plate, two side clamping arms, and a clamping arm pressing ring, and the AC analog quantity input plugs are disposed on the two side clamping arms at intervals. Each of the alternating-current analog quantity input plugs is a Y-shaped plug, the Y-shaped plug is provided with a connecting hole position for clamping a metal terminal of aninput connector, and the Y-shaped plug is connected with a signal loop line. The alternating-current analog quantity input plug of the protection device for the laboratory is low in manufacturing material cost and convenient to operate, the contact is firmer through the cooperation of the binder clip type support and the Y-shaped plugs, and the overall efficiency of a network access detection testof the alternating-current analog quantity input plug protection device is improved.

Description

technical field [0001] The invention belongs to the technical field of AC analog input plug devices, and relates to a protection device for an AC analog input plug, in particular to an AC analog input plug for a protection device used in a laboratory. Background technique [0002] At present, before the protection device installed in the substation is installed on the local site, in order to verify whether the functions of the protection device meet the operation requirements of the power grid, it must go through the laboratory network inspection test. Usually, the protection devices installed in substations have many AC analog input signals, and the wiring of the signal circuit on the backplane of the device is complicated, which generally needs to be completed according to the standard wiring process. like figure 1 As shown, each loop wiring 1 has a loop pin 2. Insert the loop pin into the AC analog terminal block 3, and then fix the loop pin with fastening screws. The te...
