Detailed Description
As shown in fig. 1, the present invention includes a rectangular elastic insulating plate with a plurality of horizontal and vertical perforations, and a conductive rod that can be inserted into the horizontal perforations. A plurality of (60 in fig. 1 for example) horizontal perforations penetrating the original elastic insulating plate are uniformly distributed along the length direction of the original elastic insulating plate 1, and the direction of the horizontal perforations is consistent with the width direction of the original elastic insulating plate; the original elastic insulating plate is provided with vertical perforations penetrating along the original elastic insulating plate corresponding to each horizontal perforation, and each horizontal perforation is communicated with the corresponding vertical perforation in a crossing manner.
The original elastic insulating plate is made of insulating materials with good elasticity, such as silicon rubber, elastic polyvinyl chloride and the like.
Each horizontal perforation corresponds to 3 vertical perforations, and the 3 vertical perforations are uniformly distributed along the direction of the corresponding horizontal perforation. One horizontal perforation is commonly referred to as "1 row" with its corresponding vertical perforation "
As shown in fig. 2, when the circuit is spliced, the original elastic insulating plate 1 is cut into elastic insulating plate segments 8 (for example, 4 short segments are 10 rows here) according to the circuit requirement. The shear points are selected at the horizontal perforations to ensure that the uncut perforations have sufficient edges to ensure that sufficient spring force is generated to press the pins of the component into intimate contact with the conductive rod after insertion of the conductive rod and component.
As shown in fig. 3, the elastic insulating plate segments 8 are transversely arranged to form an experimental composite board, the horizontal perforation at the end part of the same side of each elastic insulating plate segment is penetrated and connected by the multiple conducting rods 7 connected with the positive electrode of the power supply, and the horizontal perforation at the end part of the other side of each elastic insulating plate segment is penetrated and connected by the multiple conducting rods 7 connected with the negative electrode of the power supply. It is necessary to insert the single-time conductive rod 5 into the horizontal perforation corresponding to the vertical perforation of the plug element. The diameter of the conducting rod is slightly smaller than that of the horizontal perforation, so that the conducting rod can be smoothly inserted into the horizontal perforation, and meanwhile, no obvious gap exists. The length of the single-time conducting rod is generally equal to that of the horizontal perforation, so that the single-time conducting rod is just inserted into the horizontal perforation, and the single-time conducting rod with the length slightly larger than that of the horizontal perforation is selected for clarity of drawing, so that short heads are exposed from two ends of the horizontal perforation, and drawing and expression are facilitated.
As shown in fig. 4, the pins of the plug-in element, such as a light emitting diode 9, are inserted downward into the vertical through holes and pass out from the other side, and since the corresponding horizontal through holes have inserted therein conductive rods, the pins of the element can only slide from the sides of the conductive rods when they meet the conductive rods, however, the conductive rods are very close to the horizontal through holes in diameter, the gap is smaller than the diameter of the pins of the element, and the pins of the element need to overcome the pressing force of the elastic insulating plate, which is enough to press the pins of the element and the conductive rods tightly together to form a cross-pressing connection, thereby ensuring the conduction of the circuit.
Fig. 5 illustrates an arbitrary schematic circuit diagram, independent of the invention itself, for illustrative purposes only, and the schematic circuit diagram of fig. 5 will be populated with the present invention.
As shown in fig. 6, corresponding to the schematic circuit diagram of fig. 5, the circuit is plugged onto the experimental assembly board, and first a single conductive rod 5 (fig. 3) is inserted into the vertical through hole where the plug element or jumper is required. The length of the single-time conducting rod is slightly longer than that of the horizontal perforation, so that two ends of the single-time conducting rod are exposed, and the single-time conducting rod is convenient to show in the drawing. The actual length of the single conducting rod 5 may also be equal to the horizontal perforation length, as 5 in fig. 7. The plug-in elements and the jumper wires on the experimental composition board also correspond to the circuit schematic diagram. For example, the pull-down resistor 13 connected to the negative multiple conductive rod and the pull-up resistor 14 connected to the positive multiple conductive rod are simultaneously contacted with the single conductive rod 5 to form a series voltage division to provide base bias voltage for the NPN transistor 12.
As shown in fig. 7, the spliced circuit of the present invention can be further compact, shortening the distance between the elastic insulating plate segments, while using the single conductive bars 5 having the same length as the horizontal perforation to prevent the exposed heads of the adjacent single conductive bars from coming together. If further compactness is desired, the bread board jumper, designated by the numeral 15 in fig. 7, i.e. the same row of bread board jumpers connecting adjacent elastic insulation panel segments and the two single conductor bars 5 in contact therewith (e.g. the single conductor bars designated by the numeral 5 above in fig. 7) may be replaced by one double conductor bar (e.g. 6 in fig. 1).
The connection structure of the experiment composition board, the element and the conducting rod can be completely corresponding to a circuit schematic diagram, so that the circuit construction process is simple, convenient and efficient, and meanwhile, the spliced and inserted circuit is clear in structure like the schematic diagram and easy to analyze and improve.
The pins of the element or the pins of the bread board jumper are downwards inserted into the vertical through holes corresponding to the conductive rods and penetrate through the vertical through holes, and in the process, when the conductive rods are encountered, the pins need to press the elastic insulating plate segments and overcome the extrusion force of the elastic insulating plate segments because the diameters of the conductive rods are similar to the diameters of the horizontal through holes, and slide from the side parts of the conductive rods and downwards penetrate through the vertical through holes. At this time, the pins are connected with the conductive rods in a cross way, and reliable connection and conduction are realized by extrusion of the elastic insulating plate segments.
The pin connection direction of the two pin elements (9, 13, 14 in fig. 6) in the single elastic insulating plate segment is perpendicular to the horizontal perforation direction of the elastic insulating plate segment.
The pin connection direction of the multi-pin element (such as 10 and 12 in fig. 6) with only a single row of pins in a single elastic insulating plate segment is perpendicular to the horizontal perforation direction of the elastic insulating plate segment. Each pin is inserted into a vertical through hole corresponding to a different conductive rod.
Integrated circuits with two rows of pins (such as integrated circuits such as CD 4069) need to be plugged across adjacent segments of the resilient insulating board, each row corresponding to a segment of the resilient insulating board, each pin being inserted in a respective vertical perforation corresponding to a different conductive rod.
Two leg elements (11 in fig. 6) crossing the elastic insulating plate segments, one pin is downwardly inserted into and penetrates through the vertical perforation corresponding to the conductive rod on one of the elastic insulating plate segments, and the other pin is downwardly inserted into and penetrates through the vertical perforation corresponding to the conductive rod on the adjacent elastic insulating plate segment; the vertical perforations into which the pins of the element are inserted are the two vertical perforations nearest to the adjacent two elastic insulating plate segments.
The horizontally perforated bread board jumper (e.g., the bread board jumper labeled 15 in fig. 7) connecting the corresponding positions of adjacent elastic insulating board segments, together with the two single-time conductive rods to which it is connected, can be replaced by one double-short conductive rod (e.g., 6 in fig. 1), because the length of the double-short conductive rod is 2 times longer than the length of the horizontally perforated rod by a length equivalent to the distance between adjacent elastic insulating board segments, two horizontal jacks corresponding to the two adjacent elastic insulating board segments are exactly occupied, so that the circuit can be further simplified, and the extra inductance caused by the longer jumper can be reduced.
The connection structure of the experiment composition board, the element and the conducting rod can be completely corresponding to a circuit schematic diagram, so that the circuit construction process is simple, convenient and efficient, and meanwhile, the spliced and inserted circuit is clear in structure like the schematic diagram and easy to analyze and improve.
Meanwhile, the lengths of the elastic insulating plate and the conductive rod can be cut according to the requirements of the circuit, so that the circuit splicing and inserting test can be adapted to very complex circuit splicing and inserting test, and meanwhile, the spliced circuit is compact and practical.
After the spliced and inserted circuit is shaped, the circuit can be formed into a firm and durable practical circuit by directly packaging the circuit by using the hot melt adhesive, and complex processes such as manufacturing a printed circuit board, welding and the like are avoided.
It should be understood that the foregoing detailed description of the present invention is provided for illustration only and is not limited to the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention may be modified or substituted for the same technical effects; as long as the use requirement is met, the invention is within the protection scope of the invention.
