Abstract
The utility model discloses a self-protection lithium battery which comprises a columnar lithium battery body, an anode contact clip and a cathode contact clip. Insulating ring plates are sleeved on the anode contact clip and the cathode contact clip. Protection circuit boards are embedded on the insulating ring plates. Leads of the protection circuit boards are connected with the corresponding anode contact clip and the corresponding cathode contact clip. Compared with the existing lithium battery, the insulating ring plates are sleeved on the anode contact clip and the cathode contact clip so as to effectively avoid electric leakage of the battery; and the protection circuit boards are embedded on the insulating ring plates and the leads of the protection circuit boards are connected with the corresponding anode contact clip and the corresponding cathode contact clip so as to avoid the condition that the battery is burnt out due to overcharging, strengthen the safety performance of the battery and realize the self-protection of the battery.
Description
Technical field
The utility model relates to a kind of lithium battery, relates in particular to a kind of self-shield lithium battery.
Background technology
Lithium battery as power supply; rely on advantages such as its capacity is big, in light weight, environmental protection to obtain using widely; but more existing lithium batteries self do not have the self-protection circuit; thereby there is the situation cause battery to burn out because of overcharging; meeting initiation fire accident when serious, and battery drain also is a bigger problem.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of self-protection circuit of having, and avoids because of overcharging battery being burnt out, and effectively reduces the lithium battery of battery drain.
The technical solution of the utility model is: a kind of self-shield lithium battery; comprise the lithium battery body of column, anodal contact chip and negative pole contact chip; be with the insulation ring plate on described anodal contact chip and the negative pole contact chip; be embedded with the protective circuit plate on the described insulation ring plate, the lead-in wire of described protective circuit plate connects corresponding anodal contact chip and negative pole contact chip.
As preferably: described protective circuit plate is decided the technology microminiaturization for adopting IC nation, and has the circuit board of overcurrent insurance function.
As preferably: be coated with insulating barrier on the shell of described lithium battery body, described anodal contact chip and negative pole contact chip are the zink rod sheet.
The beneficial effects of the utility model are: be with the insulation ring plate on anodal contact chip described in the utility model and the negative pole contact chip; effectively avoid battery drain; be embedded with the protective circuit plate on the described insulation ring plate; the lead-in wire of described protective circuit plate connects corresponding anodal contact chip and negative pole contact chip; avoid the situation that causes battery to burn out because of overcharging; strengthen the security performance of battery, realize the self-protection of battery.Described protective circuit plate is decided the technology microminiaturization for adopting IC nation, and has the circuit board of overcurrent insurance function, and volume is little, effectively conserve space.Be coated with insulating barrier on the shell of described lithium battery body, avoid electric leakage, described anodal contact chip and negative pole contact chip are the zink rod sheet, conduct electricity very well.
