Abstract
The utility model relates to a rechargeable battery suitable for multimeters, which comprises a casing, a rechargeable battery core arranged in the casing and a charging circuit arranged in the casing, wherein, an output end of the charging circuit is respectively electrically connected with a positive electrode and a negative electrode of the rechargeable battery core, and an input end of the charging circuit is connected with the external of the casing through conducting wires. Due to the structural characteristics adopted by the utility model, the battery is put into a multimeter during use, the conducting wires are respectively electrically connected with a positive instrument pen and a negative instrument pen of the multimeter, and a charging switch is switched off. When the battery level is run out, the charging switch is shut down, the positive and negative instrument pens of the multimeter are separately electrically connected with the positive electrode and the negative electrode of a power supply, so that the battery can be charged, which brings convenience to users.
Description
The utility model relates to a kind of rechargeable battery, relates to a kind of rechargeable battery that is applicable to universal instrument specifically.
The known universal instrument (digital and pointer) that is used to carry out electric measurement, its inner employed battery mostly is disposable battery, or be rechargeable battery, after battery electric quantity is finished using, must take out battery in the universal instrument and change or to battery charge, this just makes troubles to the user.
The purpose of this utility model is not enough and a kind of rechargeable battery that is applicable to universal instrument is provided with regard to being at above-mentioned existing in prior technology, does not need battery taken out in the universal instrument after electric weight is finished using both can charge to this battery.
The purpose of this utility model can realize by following technical measures:
The utility model comprises housing, is arranged on the rechargeable battery core in the housing, is provided with a charging circuit in housing; The output of this charging circuit is electrically connected with the positive and negative electrode of rechargeable battery core respectively, and its input is wired to outside the housing.
Described charging circuit is made up of charge switch, RC reduction voltage circuit, rectification circuit; The output of this rectification circuit is electrically connected with the positive and negative electrode of rechargeable battery core respectively, the output of its input termination RC reduction voltage circuit, and the input of RC reduction voltage circuit is electrically connected with described lead by charge switch.
Advantage of the present utility model just is charging circuit and rechargeable battery core are combined as a whole, and draws outside the described housing, during use by lead, the utility model is packed in the universal instrument, with described lead respectively with universal instrument just, negative test pencil is electrically connected, and charge switch is disconnected both can; When the rechargeable battery electric weight used up, the charge closing switch was electrically connected the positive and negative test pencil of universal instrument respectively with the positive and negative electrode of power supply, both can charge to rechargeable battery, thereby make things convenient for the user.
The drawing of accompanying drawing is described as follows:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the schematic block circuit diagram of Fig. 1.
Fig. 3 is a profile stereogram of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises housing, is arranged on the rechargeable battery core IV in the housing, is provided with a charging circuit in housing; The output of this charging circuit is electrically connected with the positive and negative electrode of rechargeable battery core IV respectively, and its input is wired to outside the housing.Described charging circuit is formed III by charge switch I, RC reduction voltage circuit II, rectification circuit; The output of this rectification circuit III is electrically connected with the positive and negative electrode of rechargeable battery core IV respectively, the output of its input termination RC reduction voltage circuit II, and the input of RC reduction voltage circuit II is electrically connected with described lead by charge switch I.
