[0001] The utility model relates to the technical field of battery preparation, in particular to a battery and electronic equipment. Background Art

[0002] With the rapid development of science and technology, electronic devices have become an indispensable part of people's daily lives. Batteries, as an important energy supply component, are widely used in various electronic devices. After the battery is assembled, it is usually necessary to provide positive / negative electrical connectors on the positive / negative end surfaces of the battery, respectively, to facilitate the installation and connection of the battery on the electronic device. However, the lead-out ends of the existing positive / negative electrical connectors are usually provided on the two end surfaces of the battery, respectively, resulting in the need to weld the electrical connector on one end surface during installation in the electronic device, and then flip the electronic device or battery to continue welding the electrical connector on the other end surface. This welding process is relatively cumbersome, which not only increases the production process, but also reduces production efficiency. In addition, since the battery needs to be flipped over for welding twice, the uncertainty in the operation process is also increased, which may affect the welding quality and battery performance.

[0003] Therefore, in view of the above problems, it is necessary to optimize the design of the battery's electrical connectors to simplify the welding process, improve production efficiency, reduce costs, and at the same time ensure the performance and quality of the battery. Utility Model Content

[0030] See also Figures 1 to 3 A battery (10) comprises: a shell (100), a first connector (200) and a second connector (300), wherein the shell (100) comprises a first end surface (110), a side wall (120) and a second end surface (130), wherein the first end surface (110) and the second end surface (130) are spaced apart by the side wall (120); the first connector (200) is arranged on the first end surface (110), and the first connector (200) comprises a first lead-out end (210) and a connecting end (220), wherein the connecting end (220) is connected to the first end surface (110), The first lead-out end (210) is led out from the first end surface (110); the second connecting member (300) includes a first section (310), a second section (320) and a third section (330); the first section (310) is connected and arranged on the second end surface (130); the third section (330) is arranged on the first end surface (110); the second section (320) is respectively connected to the first section (310) and the third section (330) along the side wall (120); the third section (330) includes a second lead-out end (331); and the second lead-out end (331) is led out from the first end surface (110).

[0031] In the utility model, the design that the first lead-out terminal (210) and the second lead-out terminal (331) are both led out from the same end face not only simplifies the assembly process of the battery (10) in the electronic device, but also improves the accuracy, efficiency and reliability of the assembly, while optimizing the space utilization inside the device, providing more possibilities for the design and aesthetics of the device.

[0032] In another embodiment, the positions of the first connecting member (200) and the second connecting member (300) are interchanged, and the first lead-out end (210) and the second lead-out end (331) are both led out from the second end surface (130).

[0033] The battery (10) may be a button battery (10), a cylindrical battery (10), a square battery (10), etc. The present invention is described using a button battery (10) as an example.

[0034] In one embodiment, the first end face (110) is the negative terminal face, the second end face (130) is the positive terminal face, the first connector (200) is the negative terminal face, and the second connector (300) is the positive terminal face. In another embodiment, the first end face (110) is the positive terminal face, the second end face (130) is the negative terminal face, the first connector (200) is the positive terminal face, and the second connector (300) is the negative terminal face. That is, corresponding changes can be made according to actual production needs.

[0035] See also Figure 1 and Figure 2 Furthermore, the first section (310) is provided with a pin (311) protruding from the second end surface (130).

[0036] It should be noted that the design of the pin (311) increases the contact area between the battery (10) and the electronic device, thereby providing additional stability. During the installation process, the pin (311) matches the corresponding slot or fixture of the electronic device, forming a physical constraint that effectively limits the battery (10) from unnecessary rotation during installation or use. At the same time, the protruding design of the pin (311) makes it possible to more intuitively confirm the direction and position of the battery (10) during installation. The assembler can ensure that the battery (10) is inserted into the electronic device in the correct direction and position by observing and feeling the position of the pin (311), thereby avoiding rotation or improper installation due to wrong direction.

[0037] See also Figure 1 Furthermore, an insulating layer is provided between the second section (320) and the side wall (120), and a first insulating layer (140) is provided between the third section (330) and the first end surface (110).

[0038] It should be noted that a first insulating layer (140) is carefully arranged between the second section (320) and the side wall (120) of the battery (10), and between the third section (330) and the first end face (110) to ensure that the current does not short-circuit between these two contact points, thereby ensuring the safety and stability of the battery (10). The arrangement of the first insulating layer (140) not only prevents potential current leakage, but also provides important protection for the normal operation of the battery (10).

[0039] There are many ways to set the insulating layer. For example, insulating paint is applied to the second section (320) and the third section (330) on the side close to the battery (10) to form an insulating layer on the surface of the second section (320) and the third section (330); for another example, insulating tape is applied to the corresponding positions of the side wall (120) and the first end surface (110) of the battery (10), and both can achieve the effect of insulation. No limitation is made here. The present invention takes applying insulating tape as an example. This method is suitable for insulation treatment of various shapes and surfaces, is simple and quick to operate, and is more suitable for process production operations.

[0040] See also Figure 1 and Figure 3 Furthermore, the first connecting member (200) and / or the second connecting member (300) are integrally formed using a nickel sheet or a nickel-plated steel sheet.

[0041] It should be noted that connectors play a vital role in electronic devices. They are responsible for the transmission of current and the stable connection between devices. By using nickel sheets or nickel-plated steel sheets for one-piece molding, the strength and durability of the connectors are ensured, while the conductive properties are optimized to meet the needs of various electronic devices.

[0042] See also Figure 1 Furthermore, the first lead-out end (210) and the second lead-out end (331) are respectively led out from the first end surface (110) at an angle or vertically.

[0043] It should be noted that when the first lead-out terminal (210) and the second lead-out terminal (331) are inclined and led out from the first end face (110), the inclination angle is preferably between 60° and 120°, and more preferably 90°. The inclined or vertical lead-out terminal design makes the alignment during the installation process simpler and more intuitive. When the lead-out terminals are led out from the end face at a certain angle, they naturally point to the location of the connection point, providing a clear indication for the installer. Therefore, when installing the battery (10), the installer can more easily align the lead-out terminals with the corresponding interfaces of the electronic device, reducing the number of adjustments during the installation process. Due to the inclined or vertical layout of the lead-out terminals, once aligned, it is easy to insert the lead-out terminals into the corresponding slots or connectors without multiple attempts or adjustments. This not only saves installation time, but also reduces the risk of damage caused by repeated plugging and unplugging.

[0044] See also Figure 1 Furthermore, the protrusion height of the pin (311) from the second end surface (130) is ≥2 mm.

[0045] It should be noted that the pin (311) should be of sufficient length to facilitate stable connection in the electronic device. The pin (311) should be of sufficient height to provide a better contact area and connection stability, and reduce the possibility of poor contact or looseness.

[0046] See also Figure 2 and Figure 3 , further, the first section (310) is an arc-shaped structure.

[0047] The battery (10) further comprises a battery core, which is accommodated inside the housing (100) and has a spirally wound structure. One end face of the battery core is opposite to the first end face (110), and the other end face of the battery core is opposite to the second end face (130).

[0048] It should be noted that widely used spirally wound battery cells such as button batteries (10) and cylindrical batteries (10) occupy an important position in modern electronic devices due to their high energy density and simplified manufacturing process. However, due to the spiral winding method of the positive and negative electrodes, such battery cells often generate magnetic fields. In particular, when the length of the negative electrode sheet exceeds that of the positive electrode sheet, the magnetic fields generated by the two cannot offset each other, which will have adverse effects on surrounding electronic products, such as headphones, such as reduced sound quality and the appearance of background noise, which seriously affects the user experience. The first section (310) of the second connector (300) is designed to be an arc-shaped structure. The arc-shaped structure guides the current to flow in an arc-shaped path through its special shape.

[0049] The flowing current will generate a magnetic field in the opposite direction of the original magnetic field. The two will cancel each other out in space, greatly reducing the impact of the magnetic field on electronic equipment, thereby reducing background noise interference and improving user experience.

[0050] See also Figure 2 and Figure 3 Furthermore, the first section (310) includes an end portion (312), a welding portion (313) and a connecting portion (314) which are connected in sequence, the welding portion (313) is welded to the second end surface (130), a second insulating layer (150) is provided between the end portion (312) and the connecting portion (314) and the second end surface (130), and an end of the connecting portion (314) away from the welding portion (313) is connected to the second section (320).

[0051] It should be noted that the welding portion (313) and the connecting portion (314) are both arc-shaped structures, wherein the connecting portion (314) is insulated from the second end surface (130), enabling current to be drawn out from the welding portion (313) to form an arc-shaped flow path along the connecting portion (314), and the length of the end portion (312) can be adjusted to the required background noise compensation length in actual production.

[0052] Furthermore, the pin (311) is led out from the connecting portion (314), and because the connecting portion (314) is insulated from the second end surface (130), the pin (311) is arranged at the connecting portion (314) to avoid affecting the formation of an arc current as much as possible.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
