Rotation-free power connection column for physical resistance experiment

Abstract

The invention relates to the technical field of teaching equipment, in particular to a rotation-free power connection column for a physical resistance experiment. The connection column comprises a power connection column main body, the power connection column main body is connected to a power connection seat through a lead clamping seat, a lead is fixedly connected to the lead clamping seat, a pin is fixedly connected to the lead, the pin is fixedly connected to a resistor, a power connection piece is fixedly installed on the power connection column main body, a fixing structure with a rotation-free function is connected to the power connection column main body, a mistaken touch prevention structure with a moving function is installed on the fixing structure through a limiting groove, and an assembly is installed on the power connection seat through a positioning structure with a hidden opening key. The fixing structure with the rotation-free function is used on the power connection column body for external wire connection, the fixing structure adopts a pressing clamping type fixing method, rotation is not needed in the connection process, time and labor are saved, the power connection column is more suitable for being used by junior school students, and the phenomenon that the junior school students lose interest in resistance experiments is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a non-rotating and movable electric post for physical resistance experiments. Background technique [0002] Physics is an important basic subject, which plays a great role in helping students understand the nature of the world. Learning physics from shallow to deep can make students think more divergently and increase common sense in life. Generally, students begin their exposure to physics in junior high school, including basic electricity, optics, and mechanics components. Since physics is a subject that focuses on practice, many schools now offer physics experiment courses, and resistance experiment is a very important one, which allows students to intuitively understand the relationship between current and voltage. [0003] At present, electric sockets with small resistors are often used in resistance experiments. When using them, they need to be connected to the ...

AI Technical Summary

Problems solved by technology

[0003] At present, electric sockets with small resistors are often used in resistance experiments. When using them, they need to be connected to the power supply with wires. The front end of the wires usually has a fork-shaped metal sheet, which is connected to the metal electric poles. To conduct electricity, the nut structure is generally used on the current connection post, and the nut is screwed down along the thread, so that the metal sheet at the front end of the wire is pressed on the conductive sheet of the connection post. The use process is more troublesome, especially in the experimental circuit. When it is complicated, it is necessary to turn the nut many times, which is time-consuming and laborious, which affects the enthusiasm of students, and is also prone to slipping

At the same time, the current connecting poles are mostly installed in closed electric sockets, and the connecting poles and their electrical connection structures are difficult to observe, which has little teaching significance
