DE3031621A1 - Test unit for electrical experiments - has graduated set of components connected to blocks with holes for inserting wander plugs - Google Patents

Abstract

The test unit for electrical experiments has a casing (1) with a rectangular opening at the top for access to four parallel blocks which contain a set of openings (5) into which wander plugs (7) and wires (6) can be inserted. Suspended from the underside of these blocks is a large number of capacitors or resistances (2) forming a range of values, so that different values can be obtained by inserting the plugs into selected openings. The components are selected in accordance with a certain standard, and are arranged in order of e.g. resistance or capacitance. Alternatively a range of transistors, diodes etc. can be attached to the blocks, and information as to their amplification and voltage groups etc. is marked on the top.

Description

Experiment kit containing electronic components with

Plug connections The invention relates to an electronic component Containing experiment box with plug connections, such as @r for example in Experimental setup of electronic circuits is used.

Such electronic circuits contain passive components such as Resistors, capacitors, coils and the like, as well as active components such as transistors, thyristors, are integrated Circuits, etc. After an electronic circuit has been designed, a laboratory setup is required for testing, measurement to determine the component tolerances common. Have to do this Experimental socket plates (boards) have proven themselves, i.e. essentially in rows arranged sockets included.

These sockets are mostly in groups of five electrically with one another tied together. For example, the three connecting wires of a transistor in each Eille socket of three groups is plugged in, then by plugging in the connecting wires Weltere components in the remaining three times four connection hulls the transistor circuit can be completed at will.

It turned out to be disadvantageous that for the components, especially resistor and capacitor n, Ma @ -zine of all possible electrical Sizes, are to be kept ready in such a way that the required value can be found quickly will.

There are so-called resistor and capacitor decades with rotary or slide switches that allow any electrical value to be set; Apart from the size and the @rois of these devices, they have the disadvantage that they only realize one electrical value. In a Se @ tung structure, however, five resistors are required, namely resistors of not arbitrary values, but with @@ rten from the international standard series (values rounded off in steps from decimal-geometric series, e.g. "E 12 series", 1.0; 1.2; 1.5; 1.8; 2.2 .... 8.2; 10; 12 etc.). Only these values are supplied by the industry in stock.

It is true that there is a resistance box with resistors from the E series known, @@ r with a rotary switch each one of the resistors ei to @@ tetzt. If five resistances are required, then five of these must be used, all of which are in use K @@ th containing resistors must be present.

It is now very easy to switch to the one above or below Resistance values to balance the circuit. There are two types of resistance of exactly the same values are required, and is not due to the resistance in the Standard series above or below the value can be replaced, then only one further curve plug cord required; all standard resistances are connected in series (or parallel connection) of two standard resistors can be realized, for example then the 27 Ohm @@@@ ere and @ch @ eckver @@ @@, @@ one of the 15 @ @ the 12 O @ - @@ ers @dec @ebi @t @ den.

The two-part box, on the top of which the sockets @ the the plug-in cables 5 and 7 are shown, is in the drawing with 1 be @ iffert. the Plug-in cables lead to the one executed and shown in a similar manner Steckbard. So that the plug-in cables are compatible, the sockets of the experiment box have and the board has a relatively large suspension range (see. 0, up to 1.0 m), i.e. it stripped wires 6 or plugs 7 with thicker pins can be used. Because of the compact design, @ 1-pole: Search strips of the German DIN standard +1617 suitable, four of which are in the drawing (number 10) in the upper part of the housing are shown glued.

The resistors indicated by dashed lines in plan view in FIG. 1 2 are, according to Fig. 2, with the U-shaped angled connection, 3 lines differ down and up on the four tracks at the connecting ends of the socket four soldered on.

It is up to the invention to attach the components to these connections to be plugged in by means of sockets, or to combine all components on one printed circuit, Push these connection ends of the sockets, which are also extended to @ie @e, so that the copper-clad side of the pressure formwork is on the outside and there @@ all soldering points between the components and the sockets at the same time in the Solötbald.

The experiment box according to the invention with check sockets is suitable not only to install resistors and capacitors with values according to the E-Riehen, also for other components used in circuits, such as Transistors, diodes, zener diodes, @ED, NTC and PTC resistors etc. for transistors then three sockets must be made to connect the base, emitter and collector and one of each amplification factor or operating voltage group is expedient Copy to be installed.

To quickly find the components you are looking for, your electrical Expediently, the value is printed between the connection socket. An example of this shows Fig.1. The value 9 begins at the bottom left with "10 #" and increases with the standard values; 12.15, etc.
