Description
Technical field
The utility model relates to the lithium battery of metal shell.
Background technology
Along with development in science and technology, electronic product development, greatly facilitates the life of people.As portable set, its maximum feature is exactly light, therefore, and built-in limited battery capacity.And the voltage of traditional dry cell and capacity are all less; And more existing lithium batteries, such as 18650 lithium batteries, battery capacity can be accomplished comparatively large, but metal shell inside does not have baffle, in applying protective sheet situation, after the breakage of external coated rubber sheet, easily comes off, and, cannot waterproof be accomplished.Realize baffle built-in, need solution problem: by the baffle circuit of the negative pole of battery case access inside battery.
Summary of the invention
For the problems referred to above, the utility model aims to provide
a kind ofthe prismatic battery that baffle is built-in; In the inner integrated protection plate module of metal-back, whole battery is made to have short-circuit protection, over-charge protective, Cross prevention; In addition, make tailored appearance attractive in appearance.
For realizing this technical purpose, scheme of the present utility model is: the prismatic battery that a kind of baffle is built-in, comprises lithium cell and metal battery cylinder, stretches out battery core positive pole and battery core negative pole in lithium cell, and battery core negative pole and metal battery cylinder are for electrical connection; Also comprise insulation outer ring, other parts are wrapped in its inside by insulation outer ring; Burst disk and battery protecting plate is comprised in insulation inside, outer ring, battery core positive pole and burst disk are for electrical connection, the input positive pole of burst disk and battery protecting plate is for electrical connection, battery protecting plate is on burst disk, in battery protecting plate, also has baffle negative pole, when assembling battery, touch, for electrical connection with metal battery socket joint; Also comprise anode, the output cathode of anode and battery protecting plate is for electrical connection.
The beneficial effect of the technical program is: integrated protection plate in battery, is contacted, make baffle can access input negative pole by the negative pole of battery protecting plate with metal battery cylinder top crimp, solves a difficult problem for built-in baffle access battery cathode; Be integrated with the function of baffle at inside battery, more safety and applicability strong.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the prismatic battery that a kind of baffle is built-in, comprises lithium cell 1 and metal battery cylinder 2, stretches out battery core positive pole 12 and battery core negative pole 11 in lithium cell 1, and battery core negative pole 11 and metal battery cylinder 2 are for electrical connection; Also comprise insulation outer ring 3, other parts are wrapped in its inside by insulation outer ring 3; Burst disk 4 and battery protecting plate 5 is comprised in insulation inside, outer ring 3, battery core positive pole 12 and burst disk 4 are for electrical connection, the input positive pole of burst disk 4 and battery protecting plate 5 is for electrical connection, battery protecting plate 5 is on burst disk 4, in battery protecting plate 5, also has baffle negative pole 51, when assembling battery, contact with metal battery cylinder 2, for electrical connection; Also comprise anode 6, the output cathode of anode 6 and battery protecting plate 5 is for electrical connection.
Be illustrated in figure 2 the tangent plane of battery cap.Baffle negative pole 51, when battery assembles, contacts with metal battery cylinder 2 top crimp, solves and how to introduce battery cathode to this difficult problem of internal cell baffle 5.
Be illustrated in figure 3 the upward view of battery cap.Insulation outer ring 3 lower hollow, exposes metal explosion-proof sheet 4.When assembling battery, battery core positive pole 12 and burst disk 4 are for being electrically connected.
Be illustrated in figure 4 the top view after cell package.Baffle negative pole 51 contacts with metal battery cylinder 2 top crimp.
The technology of lithium battery protection board is very ripe, and there is Related product in a lot of chip producer.
protection IC has positive pole to protect and negative pole protects two kinds.
As shown in Figure 5, an exemplar schematic figure of the baffle of positive pole protection IC CT2105 is used.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
