Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

The utility model provides a kind of electricity of middle school physical experiment instructional device as shown in Fig. 1 to 12, including non- Brassboard 1, conduction connecting structure 5 and the conductive plug 6 of conductive material；The brassboard 1 is provided with several conducting metal materials The rectangle equidistant arrangement of matter and communicate the conductive tube 2 that inside is circular ring from the upper surface of brassboard 1 to lower surface；It is described to lead Electric connection structure 5, including：The conducting connecting bar 51 for the club shaped structure being made up of conductive material, at the two ends of conducting connecting bar 51 Be respectively fixedly connected with two and be conductively connected first 52 by what conductive material was constituted, two be conductively connected first 52 by with conducting connecting bar 51 perpendicular angles constitute the conduction connecting structure 5 of U shape structures, and first 52 section that is conductively connected is inside conductive tube 2 The sectional area of circular a quarter and the breach provided with a quarter circle at the vertical angle of sectional area；The conductive plug 6 are made up of conducting medium, including：Section is the first plug 61 of the area of 2 inner circular of conductive tube 1/2nd, described One end of one plug 61 is that the second circular plug 63 is fixedly connected with cross section by the connecting portion 62 of annular.

The utility model use when：

Academics and students are first one by one using conduction connecting structure 5 and leading in the way of the circuit diagram on paper uses splicing Plug 6 is inserted into the conductive tube 2 in brassboard 1, is realized completely the circuit diagram full simulation on paper on brassboard 1, And corresponding electric elements are connected in circuit using crocodile clip.Now, the circuit on brassboard 1 is exactly the electricity on paper Lu Tu, then by corresponding instrument, such as universal meter or measurement apparatus detect electric current and electricity on every connection line Pressure, the in parallel or series connection between circuit is judged with actual detection data；It can also change conductive by constantly plugging The method of attachment structure 5, gradually realizes the connection rule of complicated circuit, the instruction for facilitating teacher with this and the reason of classmate Solution.

Further, first plug 61 is another relative to the first plug 61 close to the one end of connecting portion 62 in the conductive plug 6 There is a draft angle within 1 degree one end, and draft angle big footpath one end close to the side of connecting portion 62.Further, the conduction Second plug 63 has draft angle within 1 degree close to the one end of connecting portion 62 relative to the other end of the second plug 63 in plug 6, and pulls out Big footpath one end of modular angle is close to the side of connecting portion 62.By the design of draft angle, when conductive tube 2 can cause after multiple plug Aperture becomes big, can now be likely to result in conduction connecting structure 5 and conductive tube 2 contacts unreal, and then the obstructed feelings of circuit occur Condition, which results in the mistake used.

Further, the bottom of the brassboard 1 is provided with several support columns 3, detachable by support column 3 and base 4 Connection.In view of conductive tube 2 is conducting metal material, therefore when being placed on desk, it is possible to encounter its on desk by mistake His conductive articles, and then there is short circuit and other accidents.

Further, the bottom surface of the base 4 is the collets of sucker or magnet or insulating materials.Demonstrated in teacher When, it is typically all to be explained on classroom, therefore the utility model can be vertically solid brassboard by sucker or magnet It is scheduled on blackboard or on vertical flat board, facilitates many classmates to learn together.

Further, in the conductive plug 6 the first plug 61 and/or the top end face of the second plug 63 is provided with zanjon The test trough 7 of shape., it is necessary on voltage test pencil contact conducting metal, increase when the voltage, resistance and electric current of circuit is detected After test trough 7, the nib of voltage test pencil can be just injected in test trough 7, so can not produce slide in the case of it is stable Detection conductor on voltage, resistance and electric current.

Further, the outer surface of the conducting connecting bar 51 is pasted outside colored ribbon sleeve 511, the colored ribbon sleeve 511 The uniform equidistant ring in surface arranges several monochromatic bands 512.When more conducting connecting bar 51 is spliced into conductive path successively, If way interleave is too many, then may result in classmates and be difficult to differentiate, therefore by being rotated relative to conducting connecting bar 51 Colored ribbon sleeve 511 on same conductive path, is rotated into same color, it is ensured that after the completion of splicing by colored ribbon sleeve 511, Same conductive path can regard same color as when overlooking brassboard 1, so can greatly facilitate classmates easily to divide very much Discern the trend of circuit.

For example：Parallel circuit in fig. 11 is from A point to A1, A2, A3 position beginner are not to be easy to tell connection Mode, then just can easily find out very much that the connected mode in Figure 11 is also simultaneously by the connected mode in parallel in Figure 12 Connection, the method by splitting and combining again has reached study and has been familiar with the purpose of circuit.

Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic Equivalent substitution is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc., It should be included within protection domain of the present utility model.
