DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode mounting leg structure of a battery pack which is attached to, for example, an electronic device main body and supplies power to the electronic device main body.

[0002]

2. Description of the Related Art Conventionally, a battery pack having at least a battery built therein and attached to a portable electronic device, for example, a main body of an electronic device such as a mobile phone, has a simple and robust electrode electrically connected to the main body of the electronic device. It has been demanded that there is no loosening over time, and that the above-mentioned part should be exposed to the outside so as to be securely mounted inside, so that assembling is simplified and shortened. In other words, it is desired that everyone has a uniform mounting state without any experience. Also, the number of parts for this purpose has been reduced as much as possible, and it has been demanded to manage parts and reduce costs.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an electrode terminal as a simple bent electrode terminal and to mount this bent electrode plate to a battery pack body with a simple mounting structure, and to provide a battery. It is an object of the present invention to provide an electrode mounting leg structure of a battery pack that can be securely and firmly mounted in a short time without causing aging in a mounting portion of the battery pack.

[0004]

Means for solving the problems of the present invention is to transmit power to the electronic device of a box-shaped battery pack having a structure in which at least a battery is housed and which can be attached to the electronic device body. A non-circular hole is formed in the mounting portion of the battery pack of the electrode, and a boss is inserted into this hole and the electrode is fixed by caulking, thereby facilitating the mounting with the electrode mounting leg structure of the battery pack. The simplification and the loosening of the mounting over time do not occur.

[0005]

The bent electrode plate is hooked on a hook, and the bent electrode plate is pushed from the inside to the outside so as to follow the groove. Thereafter, a non-circular hole is inserted into a boss, and the boss is caulked with heat to form the bent electrode plate. Is mounted and fixed without loosening over time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings, FIGS. 1, 2, 3, 4, and 5. FIG. FIG. 3 is an enlarged view of a portion B in FIG. 1, FIG. 4 is an enlarged view of a bent electrode plate, and FIG. 5 is an enlarged view of a main part H of FIG. Reference numeral 1 denotes a battery pack main body, and a corner 2 of the battery pack main body 1 has an opening 3 to the outside. A groove 4 is connected to the opening 3. The groove 4 is formed in a shape in which the bent electrode plate 5 can be inserted and arranged slightly forcibly. The bent electrode plates 5 are bent at substantially 90 degrees so as to be opposed to each other, and further bent at one end in the opposite direction. As a whole, the first bent portion 6, the second bent portion 7, and the third bent portion are formed. A bent portion 8 is formed.

A hole 9 is formed at the other end of the bent electrode plate 5. The hole 9 is a non-circular hole, preferably a sharp star. Of course, if it is non-circular, it need not be circular such as elliptical, elliptical, triangular or square. The hook 10 is connected to the groove 4.
Is formed, and the second bent portion 7 of the bent electrode plate 5 is formed.
Is to be hooked. The hook 10 has a cross section of just the shape, and has a structure in which the bent electrode plate 5 is inserted and hooked. A boss 11 to be inserted into the hole 9 is formed at a position corresponding to the hole 9.

That is, the dimensions of the boss 11 and the hole 9 are
The boss 11 can be inserted into the boss. When the bent electrode plate 5 is attached to the inside of the battery pack 1, the second bent portion 7 is inserted into the [-shaped portion and hooked as shown in FIG. 5 is forcibly pushed in against the elasticity of 5 and the bent electrode plate 5 is seated in the groove 4 and the boss 11 is inserted into the hole 9 to complete the temporary fixing. Finally, the bent electrode plate 5 is finally fixedly attached to the inside of the battery pack main body 1 by thermally caulking the boss 11. That is, since the hole 9 is non-circular, the hole 9 bites into the meat portion of the battery pack main body 1 at an acute angle during caulking and is securely fixed. Further, by making the battery pack non-circular, the contact area with the meat portion of the battery pack main body 1 increases, and the fixing can be continued more firmly and without aging. Since the bent electrode plate 5 is exposed at the opening 3, the electrical connection can be easily made with the electrode of the electronic device main body, and the electrical connection is also reliable because of the elasticity.

[0009]

According to the present invention, a non-circular hole is formed in a mounting portion of the battery pack of an electrode for transmitting power to the electronic device of a box-shaped battery pack having at least a battery housed therein and configured to be mountable to the electronic device body. Since the electrodes are fixed by caulking by inserting bosses into these holes, the fixing area is increased and the mounting is not only surely firm, but also there is no loosening over time. In addition, it is possible to provide an electrode mounting leg structure of a battery pack which is easy and can ensure the electrical connection with the electronic device body.

That is, the dimensions of the boss 11 and the hole 9 are
The boss 11 can be inserted into the boss. When attaching the bent electrode plate 5 to the inside of the battery pack 1, as shown in FIG. 2, the second bent portion 7 is inserted into the [-shaped portion and hooked. The bending electrode plate 5 is forcibly pushed in against the elasticity of the plate 5 to seat the bent electrode plate 5 in the groove 4 and the boss 11 is inserted into the hole 9 to complete the temporary fixing. Finally, the bent electrode plate 5 is finally fixedly attached to the inside of the battery pack main body 1 by thermally caulking the boss 11. That is, since the hole 9 is non-circular, the hole 9 cuts into the meat portion of the battery pack main body 1 at an acute angle at the time of caulking and is securely fixed. Further, by making the battery pack non-circular, the contact area with the meat portion of the battery pack main body 1 increases, and the fixing can be continued more firmly and without aging. Since the bent electrode plate 5 is exposed at the opening 3, the electrical connection can be easily made with the electrode of the electronic device main body, and the electrical connection is also reliable because of the elasticity. Further, by forming a forked shape without forming the hole, the forked shape can be fixed by being inserted into a boss and crimped. Further, a part of the hole can be cut out, and the cut-out portion can be fixed by inserting it into a boss and caulking. Needless to say, various applications are possible.
