Problems solved by technology

The pins used for terminal debugging are directly inserted into the outlet pin-type outlet pressure plate. The connection is not firm, and the pins of the terminal are easy to slip. In the work experiment, careless touch will lead to risks such as failure of startup and jumping out of the outlet.
Another connection method of the pin-type pressure plate is to use threaded experimental terminal pins. This connection method is reliable, but the threaded pins are originally used in the terminal row. If used in the pin-type outlet pressure plate, the pins will be damaged. The risk of the pin-type outlet pressure plate, resulting in poor contact of the pin-type outlet pressure plate, resulting in tripping and failure of the circuit

Abstract

The invention provides a pin-type experimental clip with an outlet pressing plate. The pin-type experimental clip with the outlet pressing plate comprises a first clamping piece, a second clamping piece and a transition section, wherein the first clamping piece is connected with the second clamping piece through the transition section; a pin is arranged between the first clamping piece and the second clamping piece; an experiment wire connection hole is arranged in the first clamping piece; a metal wire is arranged in the experiment wire connection hole; and the metal wire passes through the inside of the transition section and is electrically connected with the pin. According to the pin-type experimental clip, signal current of an experiment wire flows to the pin through the experiment wire connection hole arranged in the first clamping piece of the experimental clip and the metal wire, and the first clamping piece and the second clamping piece are firmly clamped on the pin-type outlet pressing plate through a tensile structure.

Description

technical field [0001] The invention relates to the technical field of pin connection on a press plate, and more specifically, to an outlet press plate pin-type experimental clip. Background technique [0002] To carry out the regular inspection of protection and safety automatic devices in the substation, it is necessary to test the action time of the outlet contacts of the protection and safety automatic devices. Nearly half of the outlet pressure plates of the secondary equipment in the substation are typical pin-type outlet pressure plates, but In the current work, the pins used for terminal debugging are inserted into this pin-type outlet pressure plate, and the experimental wires are connected to the pins for terminal debugging to carry out the next experimental operation. The pins used for terminal debugging are directly inserted into the outlet pin-type outlet pressure plate. The connection is not firm, and the pins of the terminal are easy to slip off. During the wo...
