Multifunctional auxiliary error correction experiment board

Abstract

The invention discloses a multifunctional auxiliary error correction experiment board and relates to the technical field of experiment devices. The multifunctional auxiliary error correction experiment board comprises an experiment board body and wire needles. The experiment board body comprises a needle hole layer and a contact layer. Cavity grooves distributed in a rectangular array mode are formed in the needle hole layer. Needle head sleeves are inserted into the cavity grooves; the two ends of the needle head sleeves extend to the two sides of the outer part of the needle hole layer respectively; a contact head is mounted at the bottom end of each needle head sleeve. Meanwhile, a spring is further arranged in each cavity groove; the spring is arranged outside each needle head sleeve in a sleeving manner; contacts distributed in a rectangular array are mounted on the upper surface of the contact layer; and the wire needles are arranged above the needle head sleeves. According to the invention, the connection relation of a circuit can be detected, the fault position can be speculated, a user can be helped correct problems; meanwhile, the circuit can be randomly built, so that the flexibility of an experiment is greatly improved, and the smooth proceeding of the experiment is facilitated.

Description

technical field [0001] The invention belongs to the technical field of experimental devices, and in particular relates to a multifunctional auxiliary error correction experimental board. Background technique [0002] Students majoring in electronics and related majors are required to conduct basic experiments in electronic technology according to the requirements of the teaching syllabus. In addition to the test instrument, the experimental device also needs an experimental board for building the circuit. [0003] Traditional experimental boards are generally divided into two types, one is soldered on the PCB, fixed connection or semi-fixed connection. There are sockets for signal input and output, power supply, control, etc. on the PCB; the other is a breadboard, which is inserted and connected by the students themselves. [0004] Among them, the advantage of PCB as an experiment board is that the connection line is simple and it is not easy to make mistakes. The disadvan...

Problems solved by technology

[0004] Among them, the advantage of PCB as an experiment board is that the connection line is simple and it is not easy to make mistakes. The disadvantage is that it limits the students' hands-on work, because the line cannot be modified at will; the advantage of breadboard as an experiment board is that it enhances the students' hands-on ability and the circuit is flexible. Difficult to correct errors in connection
