Abstract
The utility model discloses a lithium battery cover board which comprises a cover plate and a through hole arranged on the cover plate. An insulating strip is arranged at the position of the through hole. A conductive nail penetrates through the through hole to connect the cover plate with the insulating strip. Both upper and lower surfaces at the position of the through hole on the cover plate are stamped to form inner concave parts. The insulating strip is exposed out of the two surface of the cover plate so as to full fill the inner concave parts. The side walls of the inner concave parts are provided with insulating strip external expansion obstruction structures. The periphery of the outer wall of the cover plate is also provided with a leakproof layer. The lithium battery cover board has more excellent sealing performance and also has the anticreeping effect, so that the lithium battery cover board has higher safety when in use.
Description
Technical field
The utility model relates to lithium battery, particularly a kind of lithium battery cover plate.
Background technology
Lithium battery in the prior art, the cover plate of its cover plate and insulating trip be not usually because sealing effectiveness is not good, causes that insulating trip is outer easily to be stuck up, and the conduction nail is just kept by contraction elasticity usually with faying face and is connected, and reliability is not enough.Such structure makes the lithium battery of prior art not possess the fail safe of use.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of lithium battery cover plate to address the above problem fully.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of lithium battery cover plate, comprise cover plate and be arranged on through hole on the cover plate, be provided with insulating trip at lead to the hole site, described cover plate is connected by a conduction nail penetrated through via holes with insulating trip, upper and lower two surfaces, the cover plate position at described through hole place all punching press are provided with indent, described insulating trip exposes to the full indent of cover plate two surface portions, and form the bloated structure that hinders of insulating trip outward with the indent sidewall, described cover plate also is provided with an application of anti-leakage layers along its one week of outer wall.
As preferably, described conduction nail is a plain film Liu Ding, and its lower end forms a conductive electrode with the conduction compressing tablet that is in the insulating trip below.
As preferably, described application of anti-leakage layers is a rubber ring.
Compared with prior art, advantage of the present utility model is: the structure of the utility model setting makes insulating trip and cover plate sealing strong, improved the sealing of conduction nail and faying face, the application of anti-leakage layers of setting plays the situation of leaking electricity of preventing, thereby has improved fail safe of the present utility model and usability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of lithium battery cover plate, comprise cover plate 1 and be arranged on through hole 2 on the cover plate 1, be provided with insulating trip 3 in through hole 2 positions, described cover plate 1 is connected by a conduction nail 4 penetrated through via holes 2 with insulating trip 3, in the present embodiment, described conduction nail 4 is a plain film Liu Ding, its lower end forms a conductive electrode with the conduction compressing tablet 6 that is in insulating trip 3 belows, on cover plate 1 position at described through hole 2 places, the equal punching press in two surfaces is provided with indent 5 down, described insulating trip 3 exposes to the full indent 5 of 1 liang of surface portion of cover plate, and form insulating trip 3 outer expanding with indent 5 sidewalls and hinder structure, described cover plate 1 also is provided with an application of anti-leakage layers 7 along its one week of outer wall, and in the present embodiment, described application of anti-leakage layers 7 is a rubber ring.
The utility model makes insulating trip 3 and cover plate 1 hinder structure by outer the expanding of indent 5 formation that is provided with, make cover plate 1 better with the sealing binding ability of insulating trip 3, conduction nail 4 is squeezed with faying face, its sealing is improved, and the application of anti-leakage layers 7 that is formed by the rubber ring manufacturing of setting makes and the utlity model has drip-preventing function.
