DETAILED DESCRIPTION

[0045] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0046] The connector 100 and the energy storage device 400 according to embodiments of the present disclosure are described below with reference to Figs. 1-17.

[0047] As shown in Figs. 1-5, the connector 100 includes a housing 1 and an elastic conductor 2, which is arranged in the housing 1.

[0048] The housing 1 has opposite external connecting ports 1101 and internal connecting ports 1301, and the elastic conductor 2 is provided with elastic insertion ports 21 for inserting the electrical connector 600 through the external connecting ports 1101 or the internal connecting ports 1301 to clamp the electrical connector 600.

[0049] Thus, the elastic plug-in interface 21 can be arranged towards the external connecting port 1101 to plug in and cooperate with the external electric connecting piece 300, and the elastic plug-in interface 21 can be arranged towards the internal connecting port 1301 to plug in and cooperate with the internal electric connecting piece 210. Moreover, by virtue of the elastic characteristic of the elastic plug-in interface 21, the external electric connecting piece 300 and / or the internal electric connecting piece 210 can be clamped, so as to realize the power supply function.

[0050] In the example embodiment of the present disclosure, the external electric connecting piece 300 and / or the internal electric connecting piece 210 is a hard copper bar. Of course, it can also be other connecting pieces.

[0051] Thus, the application adopts the elastic piece clamping type electric connecting structure, and the electric connecting piece 600 can be directly plugged in and assembled. Compared with the prior art that the power connector is used in cooperation with the cable and the cable needs to be crimped with the power connector, the connector 100 of the application is plugged in and cooperates with the electric connecting piece 600, which is convenient to assemble, occupies small space, and can effectively avoid the problems such as stress concentration at the bending part of the cable connection and occupation of the vertical connection surface space.

[0052] Further, the elastic conductive body 2 is continuously bent to form the elastic plug-in interface 21 with the opening towards the external connecting port 1101 and the elastic plug-in interface 21 with the opening towards the internal connecting port 1301.

[0053] Thus, by continuously bending the elastic conductive body 2, a plurality of elastic plug-in interfaces 21 can be formed, and the openings of every two adjacent elastic plug-in interfaces 21 are oppositely open.

[0054] For example, the elastic conductive body 2 is continuously bent to form at least one elastic plug-in interface 21 in a substantially "N-shaped" structure to respectively plug in and cooperate with the external electric connecting piece 300 and the internal electric connecting piece 210.

[0055] At present, the power connector on the market is used for the product with the cable on the side of the box, whether in series or in parallel, at least two groups of power connectors are used for a single box, which leads to high cost of use connected therewith.

[0056] Therefore, the elastic conductive body 2 is continuously bent to form at least two elastic plug-in interfaces 21 with the opening towards the external connecting port 1101 and at least one elastic plug-in interface 21 with the opening towards the internal connecting port 1301.

[0057] Referring to FIGS. 5-7, the elastic conductor 2 is continuously bent to form at least three elastic insertion interfaces 21, generally in a "W-shaped" structure; two of the elastic insertion interfaces 21 are open toward the external connection port 1101 to be inserted and matched with the external electrical connector 300; and the other elastic insertion interface 21 is open toward the internal connection port 1301 to be inserted and matched with the internal electrical connector 210. In this way, the single connector 100 is provided with two external connection ports 1101, so that the single energy storage box 200 can be connected in series and parallel with its adjacent energy storage box 200 by using a set of connectors 100, and the cost is relatively low.

[0058] Further, the elastic conductor 2 is continuously bent and includes a plurality of laminated segments 22 arranged in layers and a bending segment 23 connecting two adjacent laminated segments 22, and the bending segment 23 and the two laminated segments 22 connected thereby form an elastic insertion interface 21.

[0059] As shown in FIGS. 5 and 7, the elastic conductor 2 can have a one-piece structure and be bent multiple times to form a laminated structure. The elastic conductor 2 can have various shapes, such as a common rectangular or square sheet structure, or other irregular shapes. Of course, the present solution does not exclude that the elastic conductor 2 can have a multi-piece structure. The multiple elastic conductors 2 can be continuously arranged in an integrated structure, and the integrated structure is bent multiple times to form a laminated structure.

[0060] The elastic conductor 2 includes laminated segments 22 arranged in layers, which are the main structure of the elastic conductor 2. The elastic conductor 2 further includes a bending segment 23 connecting two adjacent laminated segments 22, which is a structure formed by bending and can be used to limit the shell 1, thereby reducing the risk of deviation of the elastic conductor 2. The bending segment 23 extends perpendicular to the laminating direction.

[0061] The bending segment 23 can be a single structure or multiple structures. If the bending segment 23 is one, it means that the elastic conductor 2 is bent only once. If the bending segment 23 is multiple, it means that the elastic conductor 2 is bent multiple times.

[0062] For example, in FIG. 7, the bending segment 23 is multiple.

[0063] According to different bending forms of the elastic conductor 2, the bending segment 23 can have various shapes, such as an arc-shaped structure. For example, the cross-sectional shape of the bending segment 23 parallel to the laminating direction can be generally C-shaped. Or the bending segment 23 is a bent structure, i.e., the elastic conductor 2 is bent vertically, and the cross-sectional shape of the bending segment 23 parallel to the laminating direction can be generally U-shaped.

[0064] Exemplarily, in FIG. 7, the bending section 23 is in an arc structure, which has better structural stability and is less likely to be deformed by external force, and is easier to be formed.

[0065] Further, the two adjacent laminated sections 22 are oppositely curved at least at portions away from the bending section 23 to form a clamping portion 24 for clamping the electrical connector 600.

[0066] As shown in FIG. 7, the two adjacent laminated sections 22 are oppositely curved at least at portions close to the opening to form a clamping portion 24 for clamping the external electrical connector 300 / the internal electrical connector 210.

[0067] Further, the two adjacent laminated sections 22 are oppositely curved at least at portions away from the bending section 23 to form a clamping portion 24 for clamping the electrical connector 600.

Moreover, when the shell 1 or the elastic conductor 2 is damaged, it can be replaced, thereby reducing the maintenance cost.

[0070] Further, as shown in FIG. 3, FIG. 4, FIG. 8 and FIG. 14, the shell 1 comprises an outer shell 11, a middle shell 12 and a bottom shell 13, the middle shell 12 has a cavity 1201 for accommodating the elastic conductor 2, the outer shell 11 and the bottom shell 13 are buckled on opposite sides of the middle shell 12, the outer shell 11 is provided with an external connecting port 1101, and the bottom shell 13 is provided with an internal connecting port 1301.
