Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "provided," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.

Example (b):

the utility model provides a portable power source's electric core protective structure, as shown in figure 1, includes shell body 1, bubble cotton double faced adhesive tape 2, electric core subassembly 3, separation piece 4 and utmost point ear insulating glue 5, its characterized in that: the shell body 1 is provided with a battery cell cabin 11; the foam double-sided adhesive tape 2 is attached to the cell bin 11; the battery core assembly 3 is fixed on the battery cell bin 11 through a foam double-faced adhesive tape 2; the barrier pieces 4 are attached to the inner walls of the two sides of the battery cell bin 11; and the tab insulating glue 5 is wrapped at the positive and negative tabs of the electric core component 3.

Furthermore, the end part installing opening of the electric core component 3 is provided with insulating foam 6.

Furthermore, the tab insulation glue 5 is in a shape of Chinese character 'tu' or 'L'.

In this embodiment, because the cotton double faced adhesive tape 2 of bubble is pasted on electric core storehouse 11, electric core subassembly 3 fixes on electric core storehouse 11 through the cotton double faced adhesive tape 2 of bubble, consequently the power that shell body 1 received when falling can cushion through the cotton double faced adhesive tape 2 of bubble earlier and transmit electric core subassembly 3 again to whole portable power source's anti reliability of falling has been improved. Because utmost point ear insulating cement 5 parcel is in electric core subassembly 3 positive negative pole utmost point ear department, can prevent when electric core subassembly 3 displacement appears, the short circuit phenomenon appears in the contact between electric core subassembly 3 and the 3 utmost point ears of different electric core subassemblies. The end part installing port of the electric core assembly 3 is provided with insulating foam 6, so that the short circuit phenomenon occurs in the contact between the electric core assembly 3 and the electrode lugs of different electric core assemblies in space isolation. Thereby playing the role of short circuit of the double-protection electric core component 3. In order to facilitate the workers to wrap the positive and negative pole lugs of the electric core assembly 3, the lug insulation glue 5 is in a shape like a Chinese character 'tu' or in an 'L' shape, and the workers can pinch the convex one side to wrap and mount the lug through tweezers. Because the inner wall facing in both sides of electric core storehouse 11 is equipped with separation piece 4 for portable power source can prevent under the environment more abominable external foreign matter from detaining in the position gets into electric core storehouse 11. Because the foam double-faced adhesive tape 2 and the barrier sheet 4 are attached to the battery cell bin 11, the battery cell component 3 is more compact and firm to install.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
