Description

Technical Field

[0001] The utility model relates to the technical field of new energy battery packs, in particular to a copper plate buckle connection structure of an integrated busbar of a new energy battery pack. Background Art

[0002] At present, integrated busbars are installed at the conductive ends of conventional new energy battery packs. The existing integrated busbars include a busbar frame and a copper plate arranged on the side of the busbar frame. The busbar frame is mostly made of plastic material. The current structure is to open holes in the copper plate, and then the copper plate is clamped to the clamping column on the busbar frame through the hole, or an L-shaped clip is added to the edge of the copper bar to fix it. During transportation and assembly of these two structures, the copper plate will shake up and down significantly, making a relatively loud noise, and the copper plate is also easy to fall off, affecting the assembly quality of the product.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] like Figure 1-4 As shown, the utility model provides a copper plate snap-on connection structure of a new energy battery pack integrated busbar, including a busbar frame 1, the busbar frame 1 having at least two wiring harness arrangement grooves 7, a plurality of copper plates 2 are arranged side by side on the side of the wiring harness arrangement groove 7, a snap-on connection unit 4 is arranged at a position corresponding to the copper plate 2 on the side of the wiring harness arrangement groove 7, the snap-on connection unit 4 includes a snap-on pad 42 and limit plates 41 arranged on both sides above the snap-on pad 42, the copper plate 2 is laterally snapped into the gap between the snap-on pad 42 and the limit plate 41, the snap-on hole 6 on the copper plate 2 is snapped with the snap-on pad 42, and the side of the wiring harness arrangement groove 7 is provided with a support pad 5 located on the lower side of the copper plate 2.

[0016] Specifically, the buckle connection unit 4 and the harness arrangement slot 7 are an integrally formed structure, and their number and position correspond to the arrangement of the copper plate 2, wherein the buckle pad 42 supports the copper plate 2 and limits the copper plate 2 in the horizontal direction to prevent it from moving left and right, and the limit plate 41 and the buckle pad 42 together have the function of clamping the copper plate 2, which can greatly reduce the up and down shaking of the copper plate 2 and prevent the copper plate 2 from falling from the side of the harness arrangement slot 7. In addition, the limit plate 41 is L-shaped and vertically arranged, and the L-shaped limit plate 41 can limit the copper plate 2 in the up and down directions and the horizontal direction.

[0017] At the same time, the support pad 5 can provide auxiliary support for the copper plate 2 to further limit the up and down shaking of the copper plate 2.

[0018] In this embodiment, a wiring harness nickel sheet 3 extending from a wiring harness arrangement groove 7 is provided on one side of the snap connection unit 4, and the wiring harness nickel sheet 3 is welded and connected to the copper plate 2, thereby effectively utilizing the space between the snap connection units 4, reducing the relative movement between the wiring harness nickel sheet 3 and the copper plate 2, and preventing the wiring harness nickel sheet 3 from detaching from the copper plate 2.

[0019] In this embodiment, a support grid 8 is provided between the wiring harness arrangement grooves 7, and a copper plate 2 is provided at the hollow part of the support grid 8, which has a compact structure and high overall strength.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
