Description

Technical Field

[0001] This invention relates to the field of battery technology, and more specifically to a square carbon battery. Background Technology

[0002] Square carbon batteries are mainly used for power supply in bicycle headlights. They are usually made by encapsulating several dry cell batteries connected in series in an insulating shell, and then leading out the positive and negative terminals from the shell. However, the traditional square carbon battery structure has defects. When dry cell batteries are connected in series, the connecting piece can easily connect the positive and negative terminals of the same dry cell battery, causing a short circuit and damaging the battery. Summary of the Invention

[0003] To address the shortcomings of the prior art, this invention proposes a square carbon battery.

[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0005] A square carbon-zinc battery includes an upward-facing insulating shell with a cover fitted at the upper opening. The shell is divided into several battery compartments by several partitions. The battery compartments are vertically arranged and arranged side by side. Dry cell batteries are placed inside the battery compartments. The negative terminal of one dry cell battery and the positive terminal of the next dry cell battery are connected by a connecting piece from left to right. The positive terminal of the dry cell battery on the left is connected to a positive electrode plate, and the negative terminal of the dry cell battery on the right is connected to a negative electrode plate. The cover has positive and negative electrode holes corresponding to the positive and negative electrode plates, respectively. The upper end of the positive electrode plate passes through the positive electrode hole, and the upper end of the negative electrode plate passes through the negative electrode hole. The negative electrode shell of the dry cell battery is exposed. One end of the connecting piece is connected to the positive electrode, and the other end goes around the partition and is inserted between the inner wall of the adjacent dry cell battery and the corresponding battery compartment, and is connected to the side wall of the negative electrode shell of that dry cell battery. The height of the partition is higher than the height of the side wall of the dry cell battery. The lower end of the negative electrode plate is located at the bottom of the dry cell battery on the right.

[0006] In a preferred embodiment, the connection point between the connecting piece and the negative electrode shell of the dry cell is provided with a plurality of first protrusions, which connect the connecting piece to the side wall of the negative electrode shell of the dry cell through the plurality of first protrusions; the connection point between the negative electrode piece and the bottom of the dry cell is provided with a plurality of second protrusions, which connect the connecting piece to the bottom of the dry cell through the plurality of second protrusions.

[0007] In a preferred embodiment, the battery compartment is equipped with a first limiting structure to prevent the dry cell battery from shaking.

[0008] In a preferred embodiment, the first limiting structure includes a plurality of limiting protrusions distributed around the inner wall of the battery compartment. The limiting protrusions protrude from the inner wall of the battery compartment and are arranged along the vertical direction in length.

[0009] In a preferred embodiment, the inner side of the cover is provided with a plurality of second limiting structures, each including a limiting piece. The upper end of the limiting piece is fixedly connected to the cover, and the lower end of the limiting piece abuts against the dry cell battery to confine the dry cell battery within the battery compartment.

[0012] In the preferred technical solution, the distance between the positive electrode hole and the left edge of the shell cover is different from the distance between the negative electrode hole and the right edge of the shell cover.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] This invention has a simple structure and is easy to use. The height of the separator is higher than the height of the side wall of the dry cell. One end of the connecting piece is connected to the positive terminal of a dry cell. It is inserted from above the separator, around the inner wall of the adjacent dry cell and its corresponding battery compartment, so that the connecting piece is away from the negative terminal of the previous dry cell and will not make contact.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] A square carbon-zinc battery includes an insulating outer shell 1 with its opening facing upwards. A cover 2 is fitted at the upper opening of the insulating shell 1. The interior of the insulating shell 1 is divided into several battery compartments 6 by several partitions 5. The battery compartments 6 are arranged vertically and arranged side by side. Dry cell batteries 7 are placed in the battery compartments 6. The negative terminal of one dry cell battery 7 is connected to the positive terminal of the next dry cell battery 7 from left to right by a connecting piece 8. The positive terminal of the dry cell battery 7 at the left end is connected to a positive electrode plate 3, and the negative terminal of the dry cell battery 7 at the right end is connected to a negative electrode plate. 4. The cover 2 has a positive electrode hole 12 and a negative electrode hole corresponding to the positive electrode 3 and the negative electrode 4, respectively. The upper end of the positive electrode 3 passes through the positive electrode hole 12, and the upper end of the negative electrode 4 passes through the negative electrode hole. The negative electrode shell of the dry cell 7 is exposed. One end of the connecting piece 8 is connected to the positive electrode, and the other end passes around the partition 5 and is inserted between the inner wall of the adjacent dry cell 7 and the corresponding battery compartment 6 and is connected to the side wall of the negative electrode shell of the dry cell 7. The height of the partition 5 is higher than the height of the side wall of the dry cell 7. The lower end of the negative electrode 4 is located at the bottom of the right end of the dry cell 7.

[0026] The height of the separator 5 is higher than the height of the side wall of the dry cell 7. One end of the connecting piece 8 is connected to the positive terminal of a dry cell 7. It passes over the top of the separator 5 and is inserted between the inner wall of the adjacent dry cell 7 and its corresponding battery compartment 6, so that the connecting piece 8 is away from the negative terminal of the previous dry cell 7 and will not make contact. Therefore, the structure of the square carbon battery is optimized and the battery life is improved.

[0027] In a preferred embodiment, the connection point between the connecting piece 8 and the negative electrode shell of the dry cell 7 is provided with a plurality of first protrusions 13, which are connected to the side wall of the negative electrode shell of the dry cell 7 through the plurality of first protrusions 13; the connection point between the negative electrode piece 4 and the bottom of the dry cell 7 is provided with a plurality of second protrusions 15, which are connected to the bottom of the dry cell 7 through the plurality of second protrusions 15. The structure of the first protrusions 13 and the second protrusions 15 improves good contact and reduces the resistance of the contact point.

[0028] In a preferred embodiment, the battery compartment 6 is provided with a first limiting structure to prevent the dry cell battery 7 from shaking.

[0029] In a preferred embodiment, the first limiting structure includes a plurality of limiting protrusions 14 distributed around the inner wall of the battery compartment 6. The limiting protrusions 14 protrude from the inner wall of the battery compartment 6 and are arranged in the vertical direction. The dry cell battery 7 is inserted between the limiting protrusions 14 in the same battery compartment 6 and fixed inside the battery compartment 6.

[0030] In a preferred embodiment, the inner side of the cover 2 is provided with several second limiting structures, each including a limiting piece 11. The upper end of the limiting piece 11 is fixedly connected to the cover 2, and the lower end of the limiting piece 11 abuts against the dry cell battery 7, restricting the dry cell battery 7 within the battery compartment 6. Due to installation requirements, the height of the dry cell battery 7 is lower than the height of the battery compartment 6, so the dry cell battery 7 will move up and down within the battery compartment 6. The limiting piece 11 holds the dry cell battery 7 in place, pressing it firmly within the battery compartment 6.

[0031] In a preferred embodiment, the inner side of the cover 2 is provided with several positioning structures, including positioning pieces 9, which have positioning grooves 10 corresponding to the partition 5. The upper end of the partition 5 is inserted into the positioning grooves 10.

[0032] In the preferred technical solution, the connecting piece 8 is welded to the positive electrode of the dry cell 7, with two welding points, and the positive electrode piece 3 is welded to the positive electrode of the dry cell 7, with two welding points, making the welding more stable.

[0033] In the preferred technical solution, the distance between the positive electrode hole 12 and the left edge of the shell cover 2 is different from the distance between the negative electrode hole and the right edge of the shell cover 2. Since the positive and negative electrode markings are provided on the shell cover 2, through this structure, the shell cover 2 can only be covered on the insulating shell 1 in a fixed direction, and will not cause the positive and negative electrode markings to be inconsistent with the positive and negative electrodes of the battery.
