Compression joint type elements and parts board, and method for connecting the board to experimental board

Abstract

A press-joint element board is prepared for erecting said element on printed circuit board arranging insulated shell and a numbers of wiring terminals embedded in said shell on wiring bus, setting said wiring bus on printed circuit board, connecting said wiring terminals to element, containing said printed circuit board in board base and setting erection foot on said board base.

Description

technical field [0001] The invention relates to an electronic circuit experiment equipment, in particular to a crimping component board and a method for connecting it to the experiment board. Background technique [0002] Electronic research institutes, schools and electronic companies often do electronic circuit experiments in electronic product development experiments and tests. With the popularization of electronic science and technology, hundreds of millions of electronic enthusiasts often do various electronic circuit experiments by themselves. . When doing electronic circuit experiments, it is necessary to connect electronic components (transistors, thyristors, integrated circuits, etc.) and electronic devices (variable resistors, variable capacitors, input and output interfaces, system card sockets, etc.) experiment. [0003] For a long time, two methods of plugging and welding are usually used in experiments to connect electronic components to the experiment board....

AI Technical Summary

Problems solved by technology

But practice has proved that in the electronic circuit experiment, the electronic components on the experiment board are not only numerous but also densely distributed, and it is very troublesome to solder the components on the experiment board. Soldering and short-circuit faults, the distribution of components and wiring is also very disordered, which is inconvenient for circuit testing and fault finding

In many cases, some components are relatively expensive, but after being soldered to the test board, it is difficult to remove them and reuse them, which causes a serious waste of resources.

Although the plug-in connection is easy to operate and the components can be reused, the durability of the contacts is not good, the anti-vibration ability is weak, and the contact performance is poor. Failures due to poor contact often occur, resulting in test failures

Especially for complex circuit experiments and development experiments of electronic products, due to too many and complicated components and circuits to be plugged in, the distribution of patch cords used to connect components will be disordered, and the contact contact is not firm enough, which is prone to occur due to the contact falling off. Find out the problem that it is difficult to eliminate the fault due to poor contact at multiple points at the same time, resulting in a decrease in the efficiency and success rate of the experiment, and an increase in the labor intensity of the experimenter

In addition, there are many components that do not provide sockets at all, and it is impossible to use the plug-in method to complete the experiment

[0004] In addition, the use of plug-in and welding methods to access components makes it impossible to arrange components and multi-layer wiring on both sides of the experiment board, resulting in poor splicing and expansion capabilities of the experiment board
