Abstract
A battery case using variable sessions comprises a battery case body (1). A negative plate (2) and a plurality of positive plates (3) are arranged in the battery case body (1); a jack/binding post (4) corresponding to the negative plate (2) and the positive plates (3) is arranged on the battery case body (1); and the corresponding jack/binding post (4) is respectively connected with the negative plate (2) and the positive plates (3) one by one through a lead wire. The utility model has the advantages that when different battery sessions are selected according to the demands for use, a plug is only required to be inserted into a jack corresponding to the negative plate, and another plug at the other pole is inserted in another jack corresponding to the battery sessions required, and then the experimental effect corresponding to the battery sessions can be obtained; and if the battery sessions are changed, the plug at the other pole is only required to be pulled out and then inserted into the jack corresponding to the battery sessions after being changed, so that the use and the carrying are convenient, the injury caused by electric arc can not generate, and particularly, the safe operation of primary school students is ensured. The battery case has the advantages of simple structure and safe and convenient operation.
Description
Technical field
The utility model relates to the teaching appliance technical field, a kind of specifically variable battery case of joint number that uses.
Background technology
In the science of primary school (people teaches six grades first volume electromagnet of the version) teaching now, often using battery is that a batteries box or two saves, three batteries boxes; When using multiple batteries, will be together in series a plurality of battery cases, and need to use hand according to two polar conductors sometimes, if the battery joint number is many, voltage just uprises, and has hand to be taken place by the situation that electric arc burns in the time of in experiment.For example when the hot-wire coil of the different electric weight of research same number of turns of teaching students produces magnetic force strong and weak, just battery need be increased to four to five joints gradually since a joint, with the ferromagnetic plug absorption pin that inserts in the coil, use the change of magnetic field strength of different joint number batteries according to how many observations of adsorbed pin; Simultaneously, when the hot-wire coil of the different number of turns of research same charge produces magnetic force strong and weak, need be with several battery cases to study, comparatively inconvenience.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, joint number that can change battery at any time of design and the variable battery case of use joint number of observation experiment effect.
The utility model uses the variable battery case of joint number, comprise: battery box 1, a negative plate 2 and a plurality of positive plate 3 are arranged in the battery box 1, jack/binding post 4 with a negative plate 2, a plurality of positive plate 3 correspondences is arranged on the battery box 1, and corresponding jack 4 links to each other one by one with negative plate 2, positive plate 3 usefulness leads respectively.
Perhaps use the variable battery case of joint number, comprise: battery box 1, a positive plate 2 and a plurality of negative plate 3 are arranged in the battery box 1, have on the battery box 1 and a positive plate 2, a plurality of negative plate 3, corresponding jack/binding post 4, corresponding jack/binding post 4 links to each other one by one with positive plate 2, negative plate 3 usefulness leads respectively.
The utility model uses the advantage of the variable battery case of joint number to be: if when selecting the use of different battery joint numbers as required, only need insert a plug in the corresponding jack of negative plate, the plug of another utmost point is inserted in the jack of required battery joint number correspondence, can obtain the experiment effect of this battery joint number correspondence; If will change the battery joint number, only need extract another utmost point plug, be inserted in the jack of the battery joint number correspondence after the variation and get final product, use, very convenient to carry like this, the phenomenon that electric arc is hurted sb.'s feelings can not take place yet, particularly bring safety guarantee to pupil's operation, can not bring the mental handicape of fearing to the pupil, this battery pack structure is simple, handling safety, convenience.
Description of drawings
Fig. 1 is for using the structural representation of the variable battery case of joint number.
Embodiment
According to shown in Figure 1, a kind of variable battery case of joint number that uses, comprise: battery box 1, a negative plate 2 and a plurality of positive plate 3 are arranged in the battery box 1, jack/binding post 4 with a negative plate 2, a plurality of positive plate 3 correspondences is arranged on the battery box 1, and corresponding jack/binding post 4 links to each other one by one with negative plate 2, positive plate 3 usefulness leads respectively.
Be covered with the arc cover on the battery box 1.
Claims (2)
1, a kind of variable battery case of joint number that uses, comprise: battery box (1), it is characterized in that: a negative plate (2) and a plurality of positive plate (3) are arranged in the battery box (1), jack/the binding post (4) corresponding with a negative plate (2), a plurality of positive plate (3) arranged on the battery box (1), and corresponding jack/binding post (4) links to each other with lead one by one with negative plate (2), positive plate (3) respectively.
