Description

Bread board corresponding to circuit schematic diagram and simplified bread board jumper series

Technical Field

The invention belongs to the technical field of electronic circuit experiment teaching tools, and particularly relates to a novel bread board and a simplified bread board jumper series which can splice and insert an experimental circuit completely corresponding to the element direction and the wire running of a circuit schematic diagram.

Background

The schematic circuit diagram directly reflects the structure and the working principle of the electronic circuit. If the experimental circuit can completely correspond to the circuit schematic diagram in terms of element positions, wire running and the like, not only is the beginner conveniently enter the electronic circuit from the beginning of experiments, but also the electronic engineer can conveniently design, debug and analyze the electronic circuit.

The bread board has various advantages in the electronic circuit experiment, such as the electronic components can be inserted or pulled out as required, the welding is avoided, the assembly time of the circuit is saved, the components can be reused, and the like. Thus, bread boards are widely used for solderless experiments, assembly, debugging and teaching of electronic circuits. The bread board is a rectangular array formed by jacks with conductive clamping pieces inside, is a natural popularization of integrated circuit sockets, and the function of the bread board mainly depends on the connection relation between the conductive clamping pieces inside the jacks. However, the connection relationship between the conductive clips in the conventional bread board insertion hole determines that it cannot correspond to the schematic circuit diagram, for the following reasons:

the circuit schematic diagram generally adopts positive electrode wires to transversely run at the uppermost position, negative electrode wires to transversely run at the lowermost position, and most electronic elements are longitudinally arranged between the positive electrode and the negative electrode to form current, so that the analysis of the current and the voltage is facilitated. The existing bread board can realize that the positive electrode wires transversely run at the uppermost and the negative electrode wires transversely run at the lowermost, but cannot realize the longitudinal arrangement of most electronic elements, because as shown in fig. 30, 31 and 32, the element plugging areas between the positive electrode wires and the negative electrode wires of the existing bread board are divided into ten jacks in each column, two groups are divided by a central transverse isolation ditch, the conductive clamping pieces inside each group of the longitudinal five holes are mutually communicated to form a short circuit, the elements can be plugged at the break positions between the two groups only if being longitudinally arranged, each column has one group of break positions, even if two break positions between the positive electrode wires and the negative electrode wires are added, the number and the plugging positions of the elements on each column are limited seriously, and the break positions can only be plugged with two pin elements such as diodes and resistors longitudinally, so that the triode and other pin elements are required to be plugged transversely, the wiring mode is inevitably changed, the difference between the circuit schematic diagram is further increased, and the transverse arrangement elements are inconvenient to analyze current and voltage.

Before the circuit is assembled on the conventional bread board, the schematic diagram of the circuit is usually deformed and re-wired, only the connection relation among the elements is kept unchanged, the directions and positions of the elements are changed greatly, and the running of the wires are changed greatly, as compared with fig. 1 and 32. Thus, the spliced experimental circuit cannot correspond to the schematic circuit diagram in situ. The splicing and inserting process is time-consuming and labor-consuming, is prone to error, and increases the difficulty of analyzing an experimental circuit. If some changes are made in the experimental circuit, the corresponding changes in the schematic circuit diagram are also subjected to one-time complex transformation.

The -shaped bread board jumper is directly clung to the bread board due to running, is very beneficial to displaying the circuit connection relation and is superior to the soft bread board jumper in most cases. -shaped bread board jumper wires matched with the existing bread board are required to be of excessive jumper wire types for realizing different spans, and therefore the bread board jumper wire is not convenient to store and find out a proper length.

Disclosure of Invention

Aiming at the problems existing in the prior art, the invention aims to provide a novel bread board and a simplified -shaped bread board jumper wire series which can strictly correspond to a circuit schematic diagram.

In order to solve the technical problems, the invention adopts the following technical scheme:

as shown in fig. 13 and 14, a novel bread board corresponding to a circuit schematic diagram is provided, wherein one side of the novel bread board is provided with 3 rows of jacks which are positive electrode plug-in areas; the other side of the novel bread board is provided with 3 rows of jacks which are negative electrode plugging areas; as shown in fig. 14, the conductive clips inside the jacks of the positive electrode plug region are conducted with each other (hereinafter, simply referred to as "jacks are conducted with each other"); the jacks of the negative electrode plug-in area are mutually communicated. In the invention, the planes of all jack openings of the positive electrode plug-in area and the negative electrode plug-in area are called as main planes, and in the main planes, the shortest connecting line direction from the positive electrode plug-in area to the negative electrode plug-in area is longitudinal, and the direction perpendicular to the longitudinal direction is transverse. An element plugging area is arranged between the positive electrode plugging area and the negative electrode plugging area, and the element plugging area is divided into 10 identical independent plugging areas by 9 longitudinal isolation grooves. Each independent plugging area is a rectangular array formed by 5X 20 jacks, each transverse row is provided with 5 jacks, 20 transverse rows are provided, conductive clamping pieces in 5 jacks of the same transverse row are mutually communicated, and different transverse rows are mutually insulated; the different independent plug-in areas are mutually insulated.

Furthermore, one side of the novel bread board is provided with 3 to 5 horizontal rows of jacks which are positive electrode plug-in areas; the other side of the novel bread board is provided with 3 to 5 horizontal rows of jacks which are negative electrode plugging areas. The row number and the column number of the jacks of the negative electrode plug-in area are the same as those of the jacks of the positive electrode plug-in area. The conductive clamping pieces of all jacks of the positive electrode plugging area are mutually communicated; the conductive clamping pieces of the jacks of the negative electrode plug-in area are mutually conducted. An element plugging area is arranged between the positive electrode plugging area and the negative electrode plugging area, the element plugging area is divided into more than 4 rectangular independent plugging areas with the same shape by more than 3 longitudinal isolation grooves, 3 to 5 jacks are arranged in the same horizontal row in each independent plugging area, the conductive clamping pieces in the independent plugging areas are mutually conducted, 6 to 30 horizontal rows are all arranged, and the conductive clamping pieces in different horizontal rows are mutually insulated; the component plugging areas of different independent plugging areas or different split bread boards are mutually insulated.

In a preferred scheme of the invention, the standard hole center distance refers to the distance between the holes of two adjacent jacks in the same row or the same column in the same independent plug-in area, or in the same positive electrode plug-in area, or in the same negative electrode plug-in area, or in the same element plug-in area of the split bread board. The "standard pitch" of the present invention is typically defined as the standard distance of 2.54 mm from the pin center of an existing integrated circuit. The minimum hole center distance of the two jacks of the cross-anode plug-in area and the element plug-in area is 2 times of the standard hole center distance, the minimum hole center distance of the two jacks of the cross-cathode plug-in area and the element plug-in area is 2 times of the standard hole center distance, and the minimum hole center distance of the two jacks of the cross-longitudinal isolation groove is 3 times of the standard hole center distance.

Furthermore, the standard hole center distance is kept consistent in the novel bread board or the split bread board of the same model. The standard hole center distance ranges from 2 to 5 millimeters, depending on the needs. The minimum hole center distance of two jacks crossing the positive electrode plug-in area and the element plug-in area is 2 or 3 times of the standard hole center distance; the minimum hole center distance of the two jacks of the cross-cathode plug-in area and the element plug-in area is 2 or 3 times of the standard hole center distance; the minimum hole center distance of the two jacks crossing the longitudinal isolation groove is 2 or 3 or 4 times of the standard hole center distance. Thus, the hole center distances among the jacks in the same horizontal row or the same longitudinal row are integer times of the standard hole center distances, and the standardization of the jumper span of the bread board is facilitated. Some circuit schematic diagrams have a small number of wires connected in an inclined way, the lengths of the wires are determined by Pythagorean theorem and are not generally integral multiples of the standard hole center distance, and at the moment, the invention can use a small number of soft bread board jumpers to serve as the wires connected in the inclined way, and the wires are not confused because of the small number of the wires.

In another preferred scheme of the invention, a red positive electrode indication line is arranged between the positive electrode plug-in area and the element plug-in area, and a black negative electrode indication line is arranged between the negative electrode plug-in area and the element plug-in area.

The negative electrode indication line between the negative electrode plug-in area and the element plug-in area is one of cold colors, including blue, cyan, green, black, gray, etc.

Furthermore, the positive electrode indication line and the negative electrode indication line can be the same color, the upper placing position is the positive electrode indication line, and the lower placing position is the negative electrode indication line.

In a third preferred embodiment of the present invention, a split design is adopted, that is, each independent plugging area and the corresponding positive electrode plugging area and negative electrode plugging area are used as split bread boards, as shown in fig. 19 to 23. The back of the positive electrode indication line and the back of the negative electrode indication line of the split type bread board are respectively provided with a conductive column and a conductive column jack, the positive electrode conductive column and the positive electrode conductive column jack at the back of the positive electrode indication line are respectively communicated with conductive clamping pieces in jacks of the positive electrode plug-in area of the split type bread board, and the negative electrode conductive column jack at the back of the negative electrode indication line are respectively communicated with conductive clamping pieces in jacks of the negative electrode plug-in area of the split type bread board, as shown in figure 21. As shown in fig. 22, during the circuit experiment, the positive electrode conductive post is inserted into the positive electrode conductive post insertion hole of the adjacent split bread board, so that the positive electrode insertion areas of the positive electrode conductive post and the positive electrode conductive post are mutually conducted; the negative electrode conductive column is spliced with a negative electrode conductive column jack of an adjacent split bread board, so that the negative electrode splicing areas of the negative electrode conductive column and the negative electrode conductive column jack are mutually conducted. The positive electrode plugging area of the split bread board is a rectangular array formed by 5X 3 jacks, the conductive clamping pieces of the jacks are mutually communicated, 5 jacks are arranged in each transverse row, and the total number of the jacks is 3. The negative electrode plugging area of the split bread board is a rectangular array formed by 5X 3 jacks, the conductive clamping pieces of the jacks are mutually communicated, 5 jacks are arranged in each transverse row, and the total number of the jacks is 3. The element plugging area of the split bread board is a rectangular array formed by 5×20 jacks, each transverse row is provided with 5 jacks, 20 transverse rows are provided, the conductive clamping pieces of the 5 jacks of the same transverse row are mutually communicated, and the different transverse rows are mutually insulated. The minimum hole center distance of two jacks crossing the positive electrode plug-in area and the element plug-in area is 2 times of the standard hole center distance; the center distance of the minimum holes of the two jacks of the cross-cathode plug-in area and the element plug-in area is 2 times of the center distance of the standard holes; after two or more split bread boards are spliced together, the minimum hole center distance of two jacks crossing the adjacent split bread boards is 3 times of the standard hole center distance.

Further, the positive electrode plugging area of the split type bread board is a rectangular array formed by jacks, each jack is mutually communicated, 3 to 5 jacks are arranged in each transverse row, and 3 to 5 transverse rows are arranged in total. The negative electrode plug-in area of the split bread board is a rectangular array formed by jacks, the jacks are mutually communicated, 3 to 5 jacks are arranged in each transverse row, and 3 to 5 transverse rows are arranged in total. The element plugging area of the split bread board is a rectangular array formed by jacks, each transverse row is provided with 3 to 5 jacks, 6 to 30 transverse rows are all provided, the conductive clamping pieces of the jacks of the same transverse row are mutually communicated, and the different transverse rows are mutually insulated. The minimum hole center distance of two jacks crossing the positive electrode plug-in area and the element plug-in area is 2 or 3 times of the standard hole center distance; the minimum hole center distance of the two jacks of the cross-cathode plug-in area and the element plug-in area is 2 or 3 times of the standard hole center distance; after two or more split bread boards are spliced together, the minimum hole center distance of two jacks crossing the adjacent split bread boards is 2 or 3 or 4 times of the standard hole center distance.

In a fourth preferred embodiment of the present invention, two sets of battery slots may be added to the back of the new bread board, which is not a split design, as shown in fig. 3, in the prior application 201710616018.8. The outer end of the battery slot is provided with a power output block, the power output block is a bread board with 5 holes multiplied by 10 holes, and the bread board is divided into a positive electrode output area with 5 holes multiplied by 5 holes and a negative electrode output area with 5 holes multiplied by 5 holes by an isolation ditch, as shown in fig. 6. The positive electrode output area is arranged on one side of the positive electrode plug-in area, and the negative electrode output area is arranged on one side of the negative electrode plug-in area. The conductive clamping pieces of 25 jacks in the positive electrode output area are communicated with the positive electrode of the battery slot, and the conductive clamping pieces of 25 jacks in the negative electrode output area are communicated with the negative electrode of the battery slot.

A simplified series of -shaped bread board jumpers, wherein the span of the -shaped bread board jumpers (the distance between the centers of two pins) is 1 time, 3 times, 6 times, 9 times, 12 times, 15 times, 18 times and 21 times the standard hole center distance of the bread board respectively, and 2 times can be introduced if necessary. The novel bread board (figures 16, 17 and 18) and the split bread board (figures 24 and 25) which are used for the positive electrode plugging area and the negative electrode plugging area respectively have 3 transverse rows of jacks, and bread board jumpers with the same span can move up and down within the range of the transverse rows of jacks of the positive electrode plugging area and the negative electrode plugging area 3, so that the bread board jumpers can be connected to any position of the element plugging area from the positive electrode plugging area and also can be connected to any position of the element plugging area from the negative electrode plugging area when being connected to the element plugging area in one-to-three mode, as shown in figure 16. As shown in fig. 17, the connection between corresponding positions of adjacent independent plugging areas can be made by using -shaped bread board jumper 25-2 with a span of 3 times of standard hole center distance. Therefore, most of connection requirements are met, a small amount of soft bread board jumper wires can be adopted for other few oblique connection and long-distance connection, and the circuit confusion cannot be caused due to the small quantity of the soft bread board jumper wires.

Furthermore, 4 horizontal rows of jacks can be respectively arranged in the positive electrode plugging area and the negative electrode plugging area, so that the spans of the bread board jumper wires are 1 time, 3 time, 7 time, 11 time, 15 time and 19 time of the standard hole center distances of the bread boards respectively, and 2 times of the standard hole center distances can be introduced if necessary. Because the positive electrode plug-in area and the negative electrode plug-in area are respectively provided with 4 transverse rows of jacks, the bread board jumper wire with the same span can move up and down in the range of 4 holes, so that the positive electrode plug-in area and the negative electrode plug-in area can be connected to the element plug-in area in a one-to-four mode.

Furthermore, the positive electrode plugging area and the negative electrode plugging area can be respectively provided with 5 horizontal rows of jacks, and the spans of the bread board jumper wires are respectively 1 time, 3 times, 8 times, 13 times and 18 times of the standard hole center distances of the bread boards, and can be introduced 2 times if necessary. Because the positive electrode plug-in area and the negative electrode plug-in area are respectively provided with 5 transverse rows of jacks, the bread board jumper wire with the same span can move up and down in the range of 5 holes, so that the positive electrode plug-in area can be connected with the element plug-in area in a 'one-to-five' way.

The simplified bread board jumper series are summarized as follows: the center distance of two pins of each bread board jumper is taken as a span, the spans are 1 time and 2 times of standard hole center distances, other spans are in an arithmetic progression, and the tolerance expressed by taking the standard hole center distances as a unit is equal to the number of the transverse rows of the jacks in the positive electrode plug-in area.

The invention has the beneficial effects that:

(1) The novel bread board element plugging area has the advantages.

Most elements in the schematic circuit diagram are vertical, so that current flows from the uppermost positive electrode to the lowermost negative electrode, and analysis is facilitated. The longitudinal conduction relation inside the traditional bread board determines that most elements can only be transversely spliced, so that rewiring is needed, and the directions, positions and wire running of most elements in a spliced actual circuit are greatly changed compared with a schematic diagram. In contrast to fig. 1 and 32, this simple example circuit has such significant differences that it is much more different for complex circuits, thereby increasing not only the difficulty of splicing but also the difficulty of analyzing and improving the circuit. The jacks of the element plugging areas are in transverse conduction relation, so that a plurality of elements can be longitudinally plugged, and meanwhile, the transverse plugging of the elements across the isolation grooves or the transverse plugging of the elements across the split bread board can be realized through the multiple longitudinal isolation grooves or split design, so that an actual circuit spliced and plugged by the invention can completely correspond to a circuit schematic diagram, rewiring is avoided, the circuit splicing and plugging process is convenient, and the spliced and plugged experimental circuit has a clear structure like the schematic diagram and is easy to analyze and improve. The connection relation among the jacks in the element plugging area is strong in regularity, namely 'the transverse connection is broken when the grooves are broken, and the longitudinal holes are insulated', so that a beginner can accurately memorize the situation of quick operation.

(2) Simplified bread board jumper series.

As shown in figures 15 and 16, the center distances of the two pins of the simplified bread board jumper series are 1 time, 3 times, 6 times, 9 times, 12 times, 15 times, 18 times and 21 times of the standard hole center distance (25.4 mm) of the bread board. The existing bread board jumper series is shown in fig. 8, spans form an arithmetic series, the tolerance is the center distance between adjacent holes of the bread board, any two holes in the same row or the same row on the bread board can be connected, the existing bread board jumper is installed on the embodiment 1 of the invention in fig. 9, 21 different spans of bread board jumpers are needed for realizing connection from an anode plugging area to an element plugging area at any position, if 10 jumpers are needed for each span, the total number of the jumpers is up to 210, and the bread board jumper is not convenient to store and search in use; the simplified bread board jumper series has the span tolerance of 3 times of the standard hole center distance, 3 horizontal rows of jacks are arranged in the positive and negative electrode plugging areas respectively in cooperation with the embodiment 3, the arbitrary position from the positive and negative electrode plugging areas to the element plugging areas is realized by moving up and down by the method shown in fig. 16, the span variety is reduced to 8, the tolerance is larger, and the span is 3 times of the standard hole center distance (2.54 multiplied by 3=7.62 mm), so that the connection is convenient to select and is not easy to confuse.

(3) The anode and cathode plugging areas and the cathode plugging areas are improved.

The positive electrode plugging area consists of 3 to 5 horizontal rows of jacks; the negative plug-in area also consists of 3 to 5 horizontal jacks, and the design ensures that bread board jumpers from the positive plug-in area or the negative plug-in area can move up and down within the range of 3 to 5 jacks, and comparison of fig. 9 and 16 shows that the movement greatly reduces the bread board jumpers required for connecting any position of the element plug-in area from the positive plug-in area or the negative plug-in area. Meanwhile, as the number of the positive and negative jacks is increased, the use frequency of each jack is reduced, and the durability is improved.

(4) The design of the battery slot improves the advantage.

Is the content of the prior application 201710616018.8. Besides the split design, the back of the invention can be provided with two groups of battery slots, two or four batteries with No. five can be inserted according to the power supply requirement, and a 3 volt or 6 volt power supply can be provided for spliced and inserted circuits, so that the power supply requirement of most electronic circuits can be met. The spliced circuit is provided with a power supply, so that the circuit is convenient to carry and use, and the electric shock risk caused by using an external power supply is thoroughly avoided. Meanwhile, the fifth battery is the lowest in power supply cost in the existing various batteries and is also the easiest to purchase. The positive and negative electrode outputs of each group of battery slots are divided into positive electrode output areas with 5 holes and negative electrode output areas with 5 holes and 5 holes by using a bread board with 5 holes and 10 holes through an isolation ditch, and the soft bread board is used for taking electricity by jumper wires. The power supply voltage and the output current can be changed conveniently. Meanwhile, the durability of the positive electrode output area and the negative electrode output area can be guaranteed by 25 holes respectively, so that the positive electrode output area and the negative electrode output area can be enough to withstand repeated plugging and unplugging, and can also serve as a main power switch.

(5) Split design improves the advantage.

The embodiment 4 and the embodiment 5 of the invention are of split design, can be used in a random combination mode according to the size of a circuit, are suitable for a large circuit and a small circuit, and are very flexible. For a more complex large circuit, more split bread boards can be spliced and inserted together, so that a large number of elements and jumpers can be spliced and inserted in a sufficient space; the number of split bread boards can be reduced for a simpler small circuit, as shown in fig. 24, which is far smaller than fig. 10, and the comparison of the two shows the advantage of saving space when split design is used for splicing and inserting the small circuit.

Example 2 of the present invention is shown in fig. 12: the difference with the embodiment 1 is that two long rows of continuous equidistant jacks are arranged on one side of the novel bread board in the embodiment 2 transversely to the whole length and are positive electrode plugging areas; two long rows of continuous equidistant jacks are arranged on the other side of the novel bread board transversely across the whole length and are negative electrode plugging areas. The component plugging area is divided into 10 independent plugging areas by 9 longitudinal isolation grooves.

Example 3

The structure of example 3 of the present invention is as follows:

the embodiment 3 of the invention comprises a novel bread board and a simplified -shaped bread board jumper series, and a small amount of soft bread board jumpers can be added if necessary. The series of simplified -shaped bread board jumpers are shown in fig. 15, and the spans of the eight -shaped bread board jumpers are 1 time, 3 times, 6 times, 9 times, 12 times, 15 times, 18 times and 21 times of the standard hole center distance (2.54 mm in general) of the bread board, respectively, as shown in fig. 16.

As shown in fig. 13 to 16, the novel bread board of embodiment 3 of the present invention has a length longer than a width, a width direction being longitudinal, and a length direction being transverse; one side of the novel bread board is provided with 3 transverse rows of continuous equidistant jacks which are positive electrode splicing areas; the other side of the novel bread board is provided with 3 transverse rows of continuous equidistant jacks which are negative electrode plugging areas. The jacks of the positive electrode plug-in area are mutually communicated (shown as grey line segments in fig. 14); the jacks of the negative electrode plug-in area are mutually communicated (shown as grey line segments in fig. 14); the direction of the positive electrode plug-in area is called as up; the direction of the negative electrode plug-in area is 'down'. An element plugging area is arranged between the positive electrode plugging area and the negative electrode plugging area, and is divided into 10 identical rectangular independent plugging areas by 9 longitudinal isolation grooves; the minimum hole center distance of the two jacks crossing the positive electrode plug-in area and the element plug-in area is 2 times of the standard hole center distance (usually 2.54 mm), and the minimum hole center distance of the two jacks crossing the longitudinal isolation groove is 3 times of the standard hole center distance (usually 2.54 mm). The jacks in each independent plugging area form a 5×20 rectangular array, the 5 jacks in the same horizontal row are mutually communicated, and the 20 jacks in the longitudinal direction are mutually insulated. The connection relationship between the jacks on the novel bread board can be summarized as 'all transversely meet with the ditch breaking', so that the novel bread board is strong in regularity and convenient to memorize, and a beginner can quickly get on hand. Fig. 14 is a view of fig. 13, in which a plurality of gray horizontal lines are added to show the conducting relationship between the conducting clips in each jack, and the conducting clips in each jack that are connected in series by the same gray line are conducted mutually, so that all jacks in the positive electrode plugging area are conducted mutually, all jacks in the negative electrode plugging area are conducted mutually, and only 5 jacks in the same horizontal row in the same independent plugging area are conducted mutually in the element plugging area.

As shown in fig. 17 and 18, the connection mode of the component plugging areas is that the connection between the components in the same independent plugging area is mainly realized by inserting 5 jacks which are mutually communicated in the same horizontal row, and a bread board jumper wire is usually used only when the positive electrode or the negative electrode is connected. Most of the connection between adjacent independent plug-in areas is the connection between transverse rows at corresponding positions, and the connection can be realized only by adopting a bread board jumper with the span of 3 times of standard hole center distance. Other connection requirements across the independent patch areas are less common and can be accomplished with existing soft bread board jumpers, which do not confuse the circuit because of the low amount of soft bread board jumpers.

The minimum hole center distance of two jacks crossing the negative electrode plug-in area of the split type bread board and the element plug-in area of the split type bread board is 2 times of the standard hole center distance (usually 2.54 mm). Fig. 21 is a view of fig. 20 with a plurality of gray segments added to show the connection between the jacks of the split bread board, and the jacks strung by the same gray segment are connected with each other. When the gray line segment touches the positive electrode indication line, the gray line segment is communicated with the positive electrode conductive post behind the gray line segment and the positive electrode conductive post jack; when the gray line segment touches the negative electrode indication line, the gray line segment is communicated with the negative electrode conductive post and the negative electrode conductive post jack behind the gray line segment.

As shown in fig. 19: the split bread board of embodiment 4 of the present invention is provided with a positive electrode conductive post 29 and a positive conductive post jack 30 behind a positive electrode indication line 32; a negative electrode conductive post 37 and a negative electrode conductive post insertion hole 38 are provided behind the negative electrode indication line 35. As shown in fig. 22 and 23, the split bread boards can be spliced and combined according to actual requirements, the positive electrode conductive posts are inserted into the positive electrode conductive post jacks of another split bread board to conduct the positive electrode plug-in areas of the split bread board and the negative electrode conductive posts are inserted into the negative electrode conductive post jacks of another split bread board to conduct the negative electrode plug-in areas of the split bread board and the adjacent split bread boards are spliced and combined, and the minimum hole center distance of the two jacks of the split bread board is 3 times of the standard hole center distance (usually 2.54 mm).

Fig. 24 and 25 are application examples of the split bread board, and it can be seen that the experimental circuit spliced and inserted by the split bread board can also perfectly correspond to the original circuit diagram (fig. 1). Meanwhile, compared with fig. 10, the split bread board can save materials and space when the small circuit is spliced and inserted. If the circuit is larger, more split bread boards can be adopted for plugging, and the adaptability to the circuit schematic diagram is very strong.

Example 5

Embodiment 5 of the present invention is shown in fig. 26 to 29: the only difference from example 4 is that the split bread board of example 5 has 3 vertical rows of receptacles in the width direction instead of 5 vertical rows of receptacles.

The structure of comparative example 1 is as follows:

as shown in fig. 30 and 31, the length of the conventional bread board is greater than the width, the width direction is longitudinal, the length direction is transverse, 5 equidistant jacks on one side of the conventional bread board are one section, 11 sections are total, and the conventional bread board is an anode plug-in area; the 5 equidistant jacks on the other side of the existing bread board are one section, and the total of 11 sections are negative electrode plugging areas.

The left pin of the capacitor 18 and the upper pin of the electret pick-up 16 are inserted in the same horizontal row of 5 holes which are mutually communicated, and the right pin of the capacitor 18 and the middle pin (base electrode and input end) of the triode 19 are inserted in the same horizontal row of 5 holes which are mutually communicated. And the two split bread boards at the left and right legs of the capacitor 18 do not form a dc pass.

(4) In the third branch of the left number in fig. 1, only one PNP transistor 9012 is provided, and the upper leg (emitter) is connected to the positive line; the triode 20 inserted in the third split bread board from left to right in the experimental circuit of fig. 25 corresponds to the triode, and the upper leg (emitter) is conducted with the positive electrode insertion area through the bread board jumper 25-4, so that the connection relationship can be seen more clearly in cooperation with fig. 24.

(5) In fig. 1, signals are transmitted between the second branch and the third branch in the left number by wires, and signals of the upper pin (collector and output end) of the NPN transistor 9013 are transmitted to the middle pin (base and input end) of the PNP transistor 9012; the bread board jumper 25-2 inserted transversely between the element insertion area of the second split bread board and the element insertion area of the third split bread board on the experimental circuit of fig. 25 corresponds to the element insertion area of the second split bread board, the left leg of the bread board and the upper leg of the triode 19 are inserted into 5 holes communicated with each other in the same horizontal row, and the right leg of the bread board and the middle leg of the triode 20 are inserted into 5 holes communicated with each other in the same horizontal row.

(6) In fig. 1, the fourth branch has only one LED, the lower leg is connected to the negative line of the power supply, and the upper leg is connected to the lower leg (collector, output end) of PNP transistor 9012. Correspondingly, the lower leg of the light emitting diode 21 in the element plugging region of the fourth split bread board from the left on the bread board of fig. 25 is connected with the negative electrode plugging region through a -shaped bread board jumper 25-5, and the upper leg is connected with the lower leg (collector and output end) of the triode 20 through a horizontal -shaped bread board jumper 25-2.

(7) The experimental circuits of fig. 24 and 25 can be switched on and off by only supplying power to or cutting off power from the rightmost conductive post which does not participate in plugging, so that the circuit is simplified.

(8) The simple circuit in this example used only 4 split bread boards, which is much smaller than the space occupied by the experimental circuits of examples 1, 3. If the circuit is a complex circuit, more split bread boards can be inserted, so that the adaptability to the complex circuit is infinite theoretically.

Application example of comparative example 1

As shown in fig. 32, comparative example 1 shows that the correspondence between the experimental circuit on the conventional bread board and the schematic circuit diagram is poor, taking the correspondence experiment of the schematic circuit diagram in fig. 1 as an example:

(1) The distinction between the branches is no longer clear because of the absence of longitudinal isolation trenches.

(2) Because the jacks of the component plugging areas are longitudinally conducted (as shown in fig. 31), if the components are longitudinally plugged, short circuits are formed between pins, so that most components can only be longitudinally arranged on the schematic diagram to be transversely plugged in an experimental circuit (such as an electret pickup 16, a triode 19, a triode 20 and a light-emitting diode 21), and the corresponding relation between the experimental circuit and the schematic diagram is damaged by the change of the plugging direction of the components.

(3) The change of the plugging direction of the element requires the corresponding change of the running of the lead, and further damages the corresponding relation between the experimental circuit and the circuit schematic diagram.
