The utility model is provided with four kinds of connecting inserting blocks, the linear connecting inserting block, the right angle connecting inserting block, the three-way connecting inserting block and the four-way connecting inserting block. The device inserting blocks are formed by that both ends of the insulated block are respectively provided with a thin metal sheet; each device is installed between two thin metal sheets. The utility model is provided with twelve kinds of device inserting blocks in total. The inserting blocks are inserted in and connected with the bottom board so that visual and regular circuits are formed. Matched with general-purpose devices, the utility model can be used for finishing 25 demonstrating experiments and 8 grouping experiments about the electricity of the junior middle schools.

Description

Electricity experimental simulated circuit equipment for junior middle school

The utility model relates to a kind of electricity instruments used for education.

The basic operation content of Experiments of Electricity is according to circuit diagram, with lead components and parts is coupled together, and makes the student that circuit is had a visual understanding by experiment.But because the distortion of lead, the difference that components and parts profile and circuit symbol are represented is difficult to make the student that circuit is stayed map intuitively.Though existing circuit brassboard has the advantage that visibility is good and components and parts are more general, only limits to the electricity part on experiment content, and fall under the lead when vertically using, also influence is directly perceived.

The purpose of this utility model provides a kind of directly perceived, Experiments of Electricity mimic channel equipment simple in structure, that versatility is good.

The purpose of this utility model realizes by following proposal:

The utility model comprises base plate and inserted block two parts.Base plate is the dielectric panel that has several jacks.Inserted block divides and connects inserted block and device inserted block.Connect the effect that inserted block is equivalent to lead, 4 kinds of straight line, right angle, threeway and four-ways are arranged, its formation be on the collets surface by the conducting wire of forming by foil, in the collets side elastic sheet metal that is connected as a single entity with foil is arranged, lock pin is equipped with at the collets back side.The device inserted block has the lamp holder inserted block, the switch inserted block, the fixed value resistance inserted block, power supply symbol inserted block, ammeter symbol inserted block, voltmeter symbol inserted block, the multipurpose socket inserted block, the electromagnet inserted block, the rheostat inserted block, the electromagnetic relay inserted block, 12 kinds of motor model inserted block and Joule law demonstration device inserted blocks etc., it is the elastic sheet metal of foil respectively being installed and being connected as a single entity at collets two with foil, assembly ware or device symbol between two blocks of foils, respectively establish an external wire jack on two blocks of foils of symbol inserted block, there are some lock pins at the inserted block back side.

The difference of the utility model and existing circuit brassboard is to replace lead with the foil on collets surface and elastic sheet metal.Its advantage is that the circuit comparison rule that not only shows is clear, be suitable for demonstration, and the collets surface is real conducting wire or device, rather than symbol, and the intuitive of imparting knowledge to students is preferably arranged.The utility model and bar magnet, compass, current field demonstration device, the part of devices combination in the general-purpose devices such as magnetic line of force demonstration device, ammeter, voltmeter, the attached fur of glue rod, Sheffer stroke gate demonstration board can be finished 25 lecture experiments and 8 grouping experiments.

Fig. 1 is the good synoptic diagram in kind of pegging graft.

Fig. 2 is the lamp holder inserted block.Fig. 3 is the switch inserted block.Fig. 4 is the fixed value resistance inserted block.Fig. 5 is a power supply symbol inserted block.Fig. 6 is an ammeter symbol inserted block.Fig. 7 is the multipurpose socket inserted block.Fig. 8 is the electromagnet inserted block.Fig. 9 is the rheostat inserted block.Figure 10 is a voltmeter symbol inserted block.Figure 11 is the electromagnetic relay inserted block.Figure 12 is the motor model inserted block.Figure 13 is a Joule law demonstration device inserted block.Figure 14 is the straight line inserted block.Figure 15 is the right angle inserted block.Figure 16 is the threeway inserted block.Figure 17 is the four-way inserted block.

Below in conjunction with accompanying drawing the utility model is described in further detail:

With reference to accompanying drawing 14,15,16,17, arrange foil (3) at the front surface of collets (5), be in line, right angle, threeway and 4 kinds of shapes of four-way, elastic sheet metal (4) is positioned at the side of collets (5), and is connected as a single entity with foil (3).Some lock pins (6) are equipped with at the back side of collets (5).

With reference to Fig. 2,3,4,7,8,9,11,12,13, foil (3) and elastic sheet metal (4) are set at two of collets (5), between foil (3), load onto each device again, the wiring of device or contact and foil (3) join.Lock pin (6) also is equipped with at the back side of collets (5).

With reference to Fig. 5,6,10, foil (3) and elastic sheet metal (4) are loaded onto in two of collets (5), collets (5) surface rendering between foil (3) ,

Or

Symbol is offered patch jack (7) on the foil (3), lock pin (6) is equipped with at collets (5) back side.

With reference to Fig. 1, be the experimental demonstration figure in parallel that pegs graft with equipment of the present utility model.Promptly according to experimental circuit in parallel, the lock pin of each inserted block (2) is inserted in the jack of base plate (1).Grafting is convenient, circuit is directly perceived.
