Abstract
The utility model discloses an overcurrent protection battery, which comprises at least one lithium rechargeable battery or nickel-hydrogen rechargeable battery, or a normal dry battery. The utility model is characterized in that: the overcurrent protection battery also comprises an overcurrent protection circuit that consists of a fuse, a diode and a capacitance; a diode anode and a battery anode in the overcurrent protection circuit are connected in series; two ends of a diode cathode and a battery cathode are connected with the capacitance in parallel; the diode cathode is connected with the fuse in series; the other end of the fuse is provided with an output current, thus ensuring the battery not be affected by the overcurrent and preventing the electric appliances from being damaged by the overcurrent.
Description
Technical field
The utility model relates to a kind of battery, particularly a kind of battery with excess current protective function.
Background technology
The application of battery is quite extensive, and many electrical equipment all can be used.Battery can provide direct current, uses for some portable electronics.The battery of seeing on the market at present all is directly to provide power supply to electrical equipment, but when electrical equipment generation problem, especially be short-circuited or during temporary transient overcurrent, if continued power still, untimely interruption, not only influential to battery itself, shorter battery life more can cause the permanent damage of electrical appliance itself.Especially rechargeable battery can be reused many times usually, if the situation of overcurrent takes place, rechargeable battery damages probably at this point, and the price of rechargeable battery is not cheap usually.In addition, usually the battery of usefulness does not have protective circuit also can't reach that heat is substituted and purpose in parallel.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of battery with excess current protective function is provided.
The technical solution adopted in the utility model is: a kind of overcurrent protection battery; include at least one joint lithium rechargeable batteries or nickel-hydrogen chargeable cell; also can be general dry battery; it is characterized in that: the overcurrent protection battery also comprises a current protecting circuit; current protecting circuit comprises fuse, diode and electric capacity; diode anode is connected with galvanic anode in the circuit overcurrent protection; diode cathode and cell cathode two ends shunt capacitance; diode cathode series connection fuse has output current at the fuse other end.
The technical scheme that adopts the utility model to provide; the overcurrent protection battery battery that can adequately protect itself; rechargeable battery no matter; or general dry battery all can be protected; simultaneously also can make electrical appliance avoid the infringement of overcurrent; can reach also in addition that heat is substituted and purpose in parallel, make battery itself not influenced by overcurrent and can heat substitute and in parallel.
Description of drawings
Fig. 1 is the module diagram of the utility model overcurrent protection battery;
The circuit diagram of the utility model overcurrent protection battery that Fig. 2 is.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As embodiment of the present utility model, as shown in Figure 1, the overcurrent protection battery comprises body 11, is provided with battery 12 and circuit overcurrent protection 15 in the body 11, and battery 12 comprises at least one joint lithium rechargeable batteries or nickel-hydrogen chargeable cell, also can be general dry battery.As shown in Figure 2, this circuit overcurrent protection comprises resin fuse Fp, diode D and capacitor C.Diode D anode is connected with battery Vb anode in the circuit overcurrent protection 15, diode D negative electrode and battery Vb negative electrode two ends shunt capacitance C, and diode D negative electrode series connection resin fuse Fp has output current Idc at the resin fuse Fp other end.
Use of the present utility model is as follows:
Battery 12 is located in the body 11, and power supply is provided.Circuit overcurrent protection 15 also is located in this body, and is connected with battery 12, when over-current condition takes place, can cut off the power supply of battery 12.When overcurrent took place output current Idc, circuit overcurrent protection can be activated, and resin fuse Fp can be because of the overheated circuit interruption that makes, and after the resin fuse Fp cooling after a while, the temperature of resin fuse Fp descends, and circuit is opened again.Thus, can reach the purpose of protection battery and powered appliance.Also can establish a common fuse instead of resins fuse Fp 15 li of circuit overcurrent protections, thus complete interruption of power supply, unless change fuse.Diode D can make battery 12 carry out heat to substitute, and can make battery 12 be used for parallel connection simultaneously, and to protect this battery 12 power supplies, capacitor C then has the function of voltage stabilizing.
Claims (1)
1, a kind of overcurrent protection battery, include at least one joint lithium rechargeable batteries or nickel-hydrogen chargeable cell, also can be general dry battery, it is characterized in that: described overcurrent protection battery also comprises a current protecting circuit, and described current protecting circuit comprises fuse, diode and electric capacity; Diode anode described in the described circuit overcurrent protection is connected with described galvanic anode, and described diode cathode and described cell cathode two ends described electric capacity in parallel, the described diode cathode described fuse of connecting has output current at the described fuse other end.
