Description

one

The invention relates to devices for prototyping, in particular electronic circuits.

A device for prototyping electronic circuits is known, which contains a board made of transparent material with a paired grid and holes with flashes at the intersections of the grid, conductor models made of elastic material and having fastening means, and radio elements with pin-legs for mounting in slots pmeyupmi boards at the ends of the groove for fastening layouts of conductors 1.

However, a known device does not allow the layout of tracing - wiring connections between elements.

The aim of the invention is to enable tracing of conductors.

To accomplish this goal, the proposed device has a set of labeled pins with a groove in the middle for installation in the card slots and, at the ends, for fastening the conductor layouts.

The device also has a set of distance calibers, which are a step plate.

FIG. 1 shows the proposed device, a general view; in fig. 2 - mock radio elements; on fng. 3 - Layout of connecting wires with two points of attachment; pas figs. 4 - assembled layout branched electric price; pas figs. 5 - pdtyr with fixation elements in the board; in fig. 6 is a gauge for checking the lay of two conductors; in fig. 7 - layout of the connecting wire with two points

fasteners.

The proposed device contains: a rectangular plate 1 of transparent material with a HaneceHHoii pa neii coordinate grid and holes 2 in the nodes of this grid

and four legs 3; mockups of 4 radioelements with output pozhkamp 5 for installing them in the slots of the board and with means of fastening to the npm mockups of conductors — grooves at the ends; Layouts 6 of wires for marking current-carrying chains, made of elastic material, for example, of rubber, with means of attaching them to the models of radio elements, for example, loops 7 at the ends; prefabricated

mock-ups for prototyping branched chains, consisting of one long rubber band wire 8 with eyelets 9 at the ends and several short elastic bands 10 with eyelets 11 at the ends, with one end

sliding on a long elastic band; pins 12,

inserting holes into the holes 2 and performing the functions of transitional, mounting holes, contacts, contact pads, detachable connectors, test jacks and "pegs for the conductor track."

Differences in pin assignments are indicated by different pin markings. For example, it is advisable to mark the pins 12, depicting contacts, with the same color as the “current-carrying chains — conductors, and“ route pegs — from the board material.

The 13-distance gauges are stepped plates for checking the placement of conductors between two openings of different diameters, between two contact pads, between the contact pad and the openings of the diameters used. FIG. 6 shows caliber 13 for checking the placement of 2 conductors.

Layouts of radio elements placed on the board are connected to each other by means of conductor layouts according to a circuit diagram and applied. Next, the conductors 6 are traced with the help of pins 12. The elasticity of the conductors allows them to be pulled in any direction and with the help of pins 12 they can select the preferred route. The ends of the conductors 6 and 8 remain fixed on the contacts of the radio elements.

Layouts of circuits with plating pins are more convenient to perform with pins — layouts of contact pads. The prints are made in two directions for the design of duplex printing.

The possibility of laying the conductors at a given distance is checked by laying the appropriate

n-th gauge steps to two specified pins 12.

The proposed device allows the layout of the trace and

5 it is easy to sort out the options of the tracks; the conductors remain connected to the required circuit contacts. The device makes it easy and straightforward to conduct wiring of conductors.
