fig. 2 is a schematic diagram of the basic structure of the lead-acid battery according to the present application in one embodiment.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example one
Referring to fig. 1, which shows a longitudinal cross-sectional view of a battery cover of a lead-acid battery of the present invention, as shown in fig. 1, the battery cover of the lead-acid battery includes: a battery cover body 11 (see cross-hatched area) and a copper bar terminal 12 (single-diagonal hatched area); the copper bar terminal comprises a pole hole 1201, the pole hole 1201 is located at one end of the copper bar terminal, and the other end of the copper bar terminal is used for being connected with electric equipment so as to supply power to the electric equipment.
Specifically, one end of the copper bar terminal 12, which includes the pole hole 1201, is arranged inside the battery cover body 11 and is integrally injection-molded with the battery cover body 11. The battery cover body 11 is made of plastic. The copper bar terminal 11 and the battery cover body are molded by injection, so that the copper bar terminal 12 is fixed inside the battery cover body 11 when being molded with the battery cover body 11. During injection molding, the copper bar terminal 12 is fixed by the relevant structure of the injection mold, and finally, the copper bar terminal 12 is accurately positioned on the battery cover body 11. In the injection molding process, the copper bar terminal 12 is densely wrapped by the molten plastic forming the battery cover body 11, then the molten plastic is cooled and solidified, and the copper bar terminal 12 is directly fixed and sealed by the plastic, so that the sealing reliability is obviously improved compared with a method of sealing by using an adhesive, and the method has no special requirement on the plastic material used for producing the battery cover body 11. In traditional battery assembly process, need use the copper bar terminal region that "L" shape facet covered, in novel structure, also directly wrap up by the plastic, do not have the naked problem of terminal yet.
In practical implementation, the pole hole 1201 in the copper bar terminal 12 is perpendicular to the bottom of the battery cover body 11. That is to say, when the copper bar terminal 12 is disposed inside the battery cover body 11, it is necessary to ensure that the terminal hole 1201 is perpendicular to the bottom of the battery cover body 11 along the hole direction, so that after the battery cover is sealed with the battery in the battery case, it can be ensured that the vertically disposed terminal in the battery can be inserted into and connected with the terminal hole 1201 in the battery cover body 11 through the battery cover body 11.
Specifically, the bottom of the battery cover body 11 is provided with an opening communicated with the pole hole 1201, so that a pole inside the battery passes through the bottom of the battery cover body 11 and is connected with the pole hole 1201 in an inserting manner. Specifically, the opening is a circular opening having the same size as or slightly larger than the aperture of the post hole 1201, but may have other shapes as long as the post is conveniently inserted into the post hole.
Specifically, referring to fig. 1, one end 1202 of the copper bar terminal 12, which is used for being connected with an electric device, extends out of the battery cover body 11 and is located outside the battery cover body 11, so that the copper bar terminal is conveniently connected with the electric device to supply power to the electric device.
In conventional battery production, the copper bar terminal is separated from the battery cover body. Because the gap area between the copper bar terminal and the copper bar terminal assembling position on the battery cover is long and complex, the sealing of the copper bar terminal hole has certain probability by only using an adhesive to fill the gap. Referring to fig. 2, as can be seen from the area a in fig. 2, in the battery cover structure provided by the present invention, the plastic (the battery cover body) is tightly wrapped around the copper bar terminal. The sealing reliability is obviously improved compared with the method of sealing only by using the adhesive. In the conventional battery cover structure, the part of the copper bar terminal in the area B in fig. 2 is exposed, and the exposed part of the terminal needs to be covered by an L-shaped small surface patch. Can see by regional B in the picture, through improving the structure of traditional battery cover the utility model provides an among the battery cover structure, the naked part of original copper bar terminal is now wrapped up by the plastic, has not had the naked problem of terminal, no longer needs "L" shape dough sheet. Not only simplifying the assembly materials of the battery, but also saving the assembly process of the battery.
Example two
The embodiment two of the utility model provides a lead acid battery, lead acid battery includes the lead acid battery's that embodiment one provided battery cover.
The foregoing is a more detailed description of the present invention that is presented in conjunction with specific embodiments, and it is not to be understood that the specific embodiments of the present invention are limited to these descriptions. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
