    Description

    FIELD



    [0001] The present disclosure relates to the field of battery, and more particularly relates to an electric connector and a battery comprising the same.

    BACKGROUND



    [0002] In the related art, in a battery including a plurality of winding cores, an electrode terminal of a cover plate is connected to tabs of the winding cores via an electric connector. The electric connector is integrally formed and locally thinned and twisted to form a plurality of welding portions, as shown in Fig. 1. The welding portions are welded to the tabs via ultrasonic welding. During the process of ultrasonic welding, a welding head may occupy a larger space, which may cause interference with adjacent tabs while the plurality of winding cores is provided. Thus the welding between the electric connector and the tabs may be inconvenient, which may affect welding quality. Moreover, the cost of the local thinning and twisting process of the electric connector is very high, and the thinned and twisted portion has a complex structure, concentrative stress, poor flow capacity and high current density. In other words, the electric connector shows not only poor structure stability, but also high temperature during high-rate charge/discharge, which may destroy the stability of a system and cause a security problem.

    [0003] WO 2014/042005 A1 refers to a connector of a current collecting member that is welded to an electrode plate of an electrode assembly, which is constituted by a rolled material, and the current collecting member and the electrode assembly are bonded to each other by vibration welding.

    [0004] Another document is US 2005/0287431 A1 referring to a rechargeable battery.

    DETAILED DESCRIPTION



    [0028] Reference will be made in detail to embodiments of the present disclosure, where the same or similar elements and the elements having the same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.

    [0029] An electric connector 40 according to embodiments of the present disclosure will be described with reference to drawings below.

    [0030] As shown in Figs. 2 to 4, the electric connector 40 includes a leading-out sheet 100 and a plurality of connecting sheets 200.

    [0031] The plurality of connecting sheets 200 are welded to the leading-out sheet 100, and the leading-out sheet and the plurality of connecting sheets are separate parts, i.e. the electric connector is not an integrated piece. Each connecting sheet 200 includes at least two welding portions 210 configured to be welded to the tabs.

    [0032] According to the electric connector 40 of the present disclosure, the leading-out sheet is welded to the plurality of connecting sheets 200, and each connecting sheet 200 includes at least two welding portions 210, i.e. each connecting sheet 200 may be welded to at least two tabs, thus the electric connector 40 may be applied to the connection between any number of winding cores, which is not shown in drawings. In addition, by configuring the leading-out sheet 100 and the connecting sheets 200 into non-integrated pieces, an extending direction of the welding portions 210 of the connecting sheets 200 can be made the same as that of the tabs, thus there is no need to carry out a local thinning and twisting process on the electric connector 40, i.e. the electric connector according to the present disclosure does not include a thinned and twisted structure, which may simplify the structure of the electric connector 40 and decrease the process cost of the electric connector 40 on one hand, on the other hand, may avoid the impact on a weak part of the electric connector 40 during the welding process, prevent the electric connector from being broken, and may improve the flow capacity of the electric connector 40, to avoid high local temperature, so as to improve the security.

    [0033] Moreover, the electric connector 40 is of a non-integrated structure, thus during the welding process, the connecting sheets 200 may be welded to the tabs at first, then the leading-out sheet 100 may be welded to the connecting sheets 200, which may reduce the difficulty of ultra-sonic welding, thus improving the production efficiency and ensuring the welding quality.

    [0034] Thus, the electric connector 40 according to the present disclosure shows a plurality of advantages, such as a convenience of welding, a simple structure, a lower process cost, a stable and credible structure, a high security and so on.

    [0035] The electric connector 40 according to embodiments of the present disclosure will be described in detail with reference to drawings.

    [0036] In some embodiment, as shown in Figs. 2 to 4, the electric connector 40 includes a leading-out sheet 100 and a plurality of connecting sheets 200.

    [0037] In comparative and exemplary embodiments, two connecting sheets 200 are provided, and each connecting sheet 200 includes two welding portions 210, which is very suitable for the welding of four cores. If four cores (including a first core, a second core, a third core, and a fourth core) are assembled into a battery, the distance between the cores is very small, the cores must be firmly welded without damage to the tabs during the welding process. Because a leading-out sheet 100 and the plurality of connecting sheets 200 of the electric connector 40 according to the present disclosure are separate parts, two connecting sheets 200 may be welded to the tabs of two cores (i.e. the first core and the second core) at first, respectively, the welding is applied to the welding portions 210 of the two connecting sheets 200, i.e. the second vertical limb 250 or the fourth vertical limb 280. Then the two cores (i.e. the first core and the second core) may be superposed together, in which the two connecting sheets 200 are disposed on outer sides of the two cores, respectively. And, each of the above two cores (i.e. the first core and the second core) is further superposed with another core (i.e. the third core or the fourth core) at the outer side thereof, and a tab of the further superposed core (i.e. the third core or the fourth core) may be welded to the other welding portion 210 of each connecting sheet 200, i.e. the first vertical limb 240 or the third vertical limb 270. Then, the leading-out sheet 100 also extends into the two connecting sheets 200 and may be welded to the other welding portions 210 of the two connecting sheets 200, i.e. the first vertical limb 240 or the third vertical limb 270. The welding head will not interfere with adjacent tabs during the welding process, thus facilitating welding and avoiding damages to the tabs.

    [0038] In some embodiments, each of the connecting sheets 200 and the leading-out sheet 100 may be integrally formed. In some embodiments, the leading-out sheet 100 and the connecting sheets 200 may be prepared by stamping molding, which may simplify production processes of the leading-out sheet 100 and the connecting sheets 200 and improve the structural stability and performance stability of the leading-out sheet 100 and the connecting sheets 200.

    [0039] In some embodiments, the leading-out sheet 100 includes a bending portion. And a thickness of the bending portion is greater than or equal to that of a remained portion of the leading-out sheet 100. In other words, the bending portion of the leading-out sheet 100 is formed by bending with thickening, which may ensure the strength and flow capacity of the bending portion of the leading-out sheet 100 with no loss, so as to further improve the security.

    [0040] In comparative and exemplary embodiments, as shown in Figs. 2 and 3, the leading-out sheet 100 includes a horizontal portion 110 and a plurality of vertical portions 120, in which the vertical direction is shown by arrow A in figures. The horizontal portion 110 is used for connecting with an electrode terminal of a battery cover plate. The plurality of vertical portions 120 are connected to the horizontal portion 110 and then each connecting sheet 200 is welded to each vertical portion 120. Thus the plurality of vertical portions 120 may connect the plurality of connecting sheets 200 with the horizontal portion 110, such that positions of the connecting sheets 200 are suitable for welding to the tabs.

    [0041] In comparative and exemplary embodiments, as shown in Figs. 2 and 3, each vertical portion 120 includes a buffer part 130 at the middle portion thereof, and the buffer part 130 has a shape matching with that of a tab, such as an arc shape. An upper and lower part of each vertical portion 120 may be staggered in the horizontal direction via the buffer part 130. Thus, the vertical portions 120 may be arranged closer to the tabs on the one hand, on the other hand, the shape of each buffer part 130 matches with that of an un-compressed part of a core, which may limit positions of the cores and prevent the movement of the cores.

    [0042] In comparative embodiments, as shown in Fig. 2, each vertical portion 120 includes an arc transition at an edge thereof, i.e. the first arc transition 121, which may prevent the cores from being damaged by the vertical portions 120 during vibration. In some embodiments, each connecting sheet 200 is also configured with an arc transition at an edge thereof, i.e. the second arc transition 220, which may prevent the cores from being damaged by the connecting sheets 200 during vibration.

    [0043] In comparative embodiments, as shown in Fig. 2, each vertical portion 120 includes an arc end 122 away from the horizontal portion 110. The arc end 122 may be used as an assembly guide, so as to facilitate assembly.

    [0044] In comparative embodiments, as shown in Fig. 2, each connecting sheet 200 has a substantially U-shaped horizontal cross section. In some embodiments, each connecting sheet includes a vertical connecting limb 230, a first vertical limb 240, and a second vertical limb 250. The vertical connecting limb 230, the first vertical limb 240 and the second vertical limb 250 are located outside of the vertical portion 120 of the leading-out sheet 100. The first vertical limb 240 and the second vertical limb 250 are connected to two side edges of the vertical connecting limb 230 respectively and spaced apart from each other, the first vertical limb 240 is welded to the vertical portion 120 of the leading-out sheet 100, and the first vertical limb 240 and the second vertical limb 250 are configured to form two welding portions 210 respectively. In other words, the first vertical limb 240 is welded to the leading-out sheet 100 and a tab, while the second vertical limb 250 is only welded to a tab. Thus spaces occupied by the leading-out sheet 100 and the connecting sheets 200 may be overlapped, which may significantly reduce the space occupied by the electric connector 40 and maximize the battery capacity.

    [0045] In exemplary embodiments, as shown in Fig. 3, each connecting sheet 200 has a substantially U-shaped vertical cross section. In some embodiments, each connecting sheet 200 includes a horizontal connecting limb 260, a third vertical limb 270, and a fourth vertical limb 280. The third vertical limb 270 and the fourth vertical limb 280 are located outside of the vertical portion 120 of the leading-out sheet 100, and the horizontal connecting limb 260 is located below the vertical portion 120 of the leading-out sheet 100. The third vertical limb 270 and the fourth vertical limb 280 are connected to two ends of the horizontal connecting limb 260 respectively and spaced apart from each other, the third vertical limb 270 is welded to the vertical portion 120 of the leading-out sheet 100, and the third vertical limb 270 and the fourth vertical limb 280 are configured to form two welding portions 210 respectively. In other words, the third vertical limb 270 is welded to the leading-out sheet 100 and a tab, while the fourth vertical limb 280 is only welded to a tab. Thus spaces occupied by the leading-out sheet 100 and the connecting sheet 200 may be overlapped, which may significantly reduce the space occupied by the electric connector 40 and maximize the battery capacity.

    [0046] In exemplary embodiments, as shown in Fig. 3, each connecting sheet 200 further includes a horizontal supporting limb 290. The horizontal supporting limb 290 is connected to an end of the fourth vertical limb 280 away from the horizontal connecting limb 260, and extends toward the third vertical limb 270. The horizontal supporting limb 290 has an arc transition to connect with the fourth vertical limb 280. With the above structure, the connecting sheets 200 can be prevented from scratching tabs and deforming.

    [0047] The battery 1 according to embodiments of the present disclosure will be described with reference to drawings below.

    [0048] As shown in Fig. 4, the battery 1 according the present disclosure includes a shell 10, a cover plate 20, a plurality of winding cores, and an electric connector.

    [0049] The shell 10 defines an accommodating chamber 11 therein. The cover plate 20 is mounted to the shell 10 and configured to seal the accommodating chamber 11. The cover plate 20 has an electrode terminal formed thereon, which is not shown in drawings. The plurality of winding cores is received in the accommodating chamber 11. The electric connector is the electric connector 40 according to embodiments of the present disclosure. The electric connector 40 is received in the accommodating chamber 11, and the leading-out sheet 100 is connected to the electrode terminal. In some embodiments, each winding core is provided with a tab 30, and each connecting sheet 200 is welded to the tabs 30 of at least two winding cores by the welding portions 210.

    [0050] The battery 1 according to the present disclosure, with the electric connector 40 according to the present disclosure, shows a plurality of advantages, such as a convenience of manufacturing, a lower cost, a safe and credible performance and so on.

    [0051] Other structures and operations of the battery 1 according to embodiments of the present disclosure are known to those skilled in the art, and thus will not be described in detail here.
