Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
Referring to fig. 1, an electronic apparatus 1000 includes a battery 100 and a functional device 200. The functional device 200 is electrically connected to the battery 100 to supply power to the functional device 200 through the battery 100. In a specific implementation, the battery 100 includes a wound battery cell 10, the wound battery cell 10 includes a pole core 120 made by winding a positive pole sheet, a separator, and a negative pole sheet, and generally includes a casing 110. When the battery works, because the wound positive and negative pole pieces are arranged in a spiral shape, an alternating magnetic field can be generated when the battery works dynamically, and the alternating magnetic field affects the functional device 200 of the load.
Taking the electronic device 1000 as a wireless bluetooth headset as an example, when the battery 100 works, the current flowing through the winding electric core 10 may generate a dynamic alternating interference magnetic field, and may couple with a speaker coil of the wireless bluetooth headset at a specific frequency signal to form a strong signal, so that the speaker generates a noise floor at the specific frequency when working statically, which strongly affects the user experience.
Referring to fig. 2 to 12, in order to improve the above problem, the present application discloses a battery 100, which includes the aforementioned winding cell 10 and at least one connecting member 40.
The connecting member 40 is made of a conductive material, and is used for electrically leading out one pole of the wound battery cell 10 and generating a magnetic field when current passes through the connecting member. The connection member 40 includes an extension part 420, a curvature of the extension part 420 is substantially the same as a winding curvature of the pole piece 120, and the extension part 420 is disposed substantially coaxially with the pole piece 120. It should be noted that, ideally, the curvature of the extension part 420 may be the same as the winding curvature of the pole core 120, but since the pole core 120 is wound in a spiral shape and is limited by the process precision, the curvature of the extension part 420 is substantially the same as the winding curvature of the pole core 120, which can be understood as follows: the curvature of the arc corresponding to the extension portion 420 is substantially equal to the curvature of the outermost periphery of the wound battery cell 10, and may have a certain deviation within the range of the process accuracy limitation, rather than being completely equal. Similarly, the substantially coaxial arrangement of the extension part 420 and the pole piece 120 can be understood as follows: the axis of the arc corresponding to the extension portion 420 substantially coincides with the winding axis of the pole piece 120, and may have a certain deviation within the range of the process progress limitation.
One end of the extending portion 420 is electrically connected to one of the positive electrode tab and the negative electrode tab, and the other end is used for electrically connecting to an external load. In a normal case, the other end of the extension part 420 may be connected with an electrical connection contact provided to the electronic device 1000.
Meanwhile, the connection member 40 is configured to: when the battery 100 is in a power supply state, the magnetic field generated by the current passing through the connecting member 40 at least partially cancels the magnetic field generated by the current passing through the pole piece 120. Specifically, the extension 420 of the connecting member 40 has a curved shape, and in a specific embodiment, may be configured as a circular arc. The curvature of the extension part 420 is substantially the same as that of the pole core 120, and the axis of the extension part 420 is substantially overlapped with the winding axis of the pole core 120, so that when the battery 100 operates, the current passing through the pole core 120 is substantially the same as the current passing through the extension part 420, and in a specific implementation, the width of the extension part 420 can be adaptively adjusted by simultaneously considering the length difference of the positive and negative pole pieces, the radius difference of the inner and outer rings of the pole core, the width difference of the positive and negative pole pieces, the typical current magnitude of the battery 100 during charging and discharging, and other factors, so that the magnetic field generated by the current passing through the connecting piece 40 at least partially offsets the magnetic field generated by the current passing through the pole core 120. Based on the disclosure of the present application, one skilled in the art can adjust the width of the extension part 420 accordingly based on the basic calculation rule of the magnetic field and the aforementioned factors to try to cancel the magnetic field generated by the current passing through the pole piece 120.
In particular implementations, there are many variations in the specific structure of the battery 100 and, accordingly, many different embodiments of the specific form of the connecting member 40. The following detailed description is to be read in connection with specific embodiments.

One end of the extension part 420 of the connector 40 is electrically connected to the positive electrode lead-out part 20, or one end of the extension part of the connector 40 is electrically connected to the negative electrode lead-out part 30. In other words, the battery pack 100 may include only one connector 40, and the connector 40 may be electrically connected to one of the positive electrode lead-out portion 20 and the negative electrode lead-out portion 30 to satisfy the aforementioned functions.
In a specific implementation, the positive electrode lead-out part 20 and the negative electrode lead-out part 30 may be disposed on the same side of the winding core 10. One of the positive electrode lead-out portion 20 and the negative electrode lead-out portion 30 is configured as a core cover. For convenience of understanding, the description will be given by taking the case where the negative electrode lead-out portion 30 constitutes the core cover as an example, and it is understood that the positive electrode lead-out portion 20 may constitute the core cover in a specific embodiment.
The positive lead-out 20 may be provided as a rivet. The rivet is fixedly connected to the middle of the pole core cover plate and is electrically connected with the positive plate of the pole core 120.

In a specific implementation, the battery 100 further includes an insulating member 50 for insulating the portion of the lead-out member 40 except for the fixing portion 420 from the pole piece 120. Specifically, a first insulator 510 and a second insulator 520 may be included. The first insulator 510 may be provided around the outer periphery of the wound cell 10, and may be specifically attached to the outer periphery of the pole core 120. The second insulating member 520 is interposed between the pole piece cover plate and the portion between the fixing portion 410 and the connection portion 430 of the connection member 420. Therefore, the insulation between the connecting strip 40 and the pole core 120 from the welding point position to the connecting part 430 can be ensured, and further, the working current of the electronic device 1000 is equal to the current flowing out from the pole piece in the pole core 120 as much as possible, so that more accurate control is realized.
Generally, the insulator material used for the first insulator 510 and the second insulator 520 may include PI, PP, PET, PVC, PC, or other common engineering materials, or paper, glass fiber, insulating cloth, and preferably uses a high resistance material, and if necessary, a material with a certain conductivity may also be used.
