[0034] The following will describe in more detail the exemplary embodiments disclosed in the present application with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the specific embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be fully communicated to those skilled in the art.

[0035] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present application; that is, not all features of actual embodiments are described here, and well-known functions and structures are not described in detail.

[0036] In the drawings, for the sake of clarity, the dimensions of layers, regions, elements, and their relative dimensions may be exaggerated. Throughout the drawings, like reference numerals indicate like elements.

[0037] It should be understood that when an element or layer is referred to as being "on", "adjacent to", "connected to", or "coupled to" another element or layer, it can be directly on, adjacent to, connected to, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on", "directly adjacent to", "directly connected to", or "directly coupled to" another element or layer, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Thus, a first element, component, region, layer, or section discussed below may be denoted as a second element, component, region, layer, or section without departing from the teachings of the present application. And when discussing a second element, component, region, layer, or section, it does not necessarily imply that a first element, component, region, layer, or section exists in the present application.

[0038] Spatial relationship terms such as "under", "below", "beneath", "underneath", "above", "over", etc. are used herein for convenience in describing the relationship of one element or feature shown in the figures to other elements or features. It should be understood that, in addition to the orientation shown in the figures, spatial relationship terms are intended to include different orientations of the device in use and operation. For example, if the device in the figures is flipped, then an element or feature described as "under" or "beneath" or "underneath" another element or feature will be oriented "over" the other element or feature. Thus, the exemplary terms "under" and "beneath" can include both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or other orientations) and the spatial descriptors used herein are to be interpreted accordingly.

[0039] The purpose of the terms used herein is only to describe specific embodiments and is not a limitation of the present application. As used herein, the singular forms "a", "an" and "the" are also intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprising" and / or "including", when used in this specification, identify the presence of the stated features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups. As used herein, the term "and / or" includes any and all combinations of the related listed items.

[0040] To thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other embodiments.

[0041] As Figures 1 to 7 shown, a connection structure provided by an embodiment of the present application is used to connect a wire harness to a mounting object 200. As an example, the mounting object 200 is a box inside a battery pack. Of course, it is not limited thereto, and it may also be components such as a platform or a bracket.

[0042] Specifically, the connection structure includes a clamping member 10, a steering member 20, and a tightening member 30. The clamping member 10 includes a buckle portion 11, a pressing portion 12, and a limiting portion 13. The pressing portion 12 is located between the buckle portion 11 and the limiting portion 13. The buckle portion 11 is used to be clamped to the mounting object 200, and the pressing portion 12 is used to abut against the surface of the mounting object 200 when the buckle portion 11 is clamped to the mounting object 200. The limiting portion 13 is provided with a first through hole 131 having an arc-shaped structure. The buckle portion 11 can enable the connection structure to be connected to the mounting object 200, and the pressing portion 12 can further improve the connection firmness between the connection structure and the mounting object 200.

[0043] The steering member 20 is at least provided with a second through hole 210. The second through hole 210 is sleeved with the first through hole 131, and the steering member 20 moves along the path of the first through hole 131 through the second through hole 210. It can be understood that the steering member 20 can move along an arc-shaped path in the arc-shaped first through hole 131 to adjust the position and posture of the wire harness to achieve multi-directional adjustment and multi-angle adjustment, and can make the wire harness be fixed with balanced force.

[0044] The tightening member 30 is connected to the steering member 20, and the tightening member 30 is used to bundle the wire harness. The tightening member 30 can be bent and self-locked, and the tightening member 30 automatically adjusts the self-locking area according to the specific situation of the wire harness. As an example, the tightening member 30 is a cable tie. Of course, it is not limited thereto.

[0045] The above connection structure can not only achieve multi-directional and multi-angle adjustment, but also be recycled.

[0046] Figure 3 It is shown in that the steering member 20 moves along the path of the first through hole 131, that is, Figure 3 the direction of the arrow m shown in, to adjust the position and attitude of the steering member 20, and further adjust the position and attitude of the wire harness.

[0047] In an alternative embodiment, the buckle portion 11 has a plurality of elastic laminations 111 stacked in sequence along the first direction, that is, Figure 2 the direction of the arrow s1 shown in. The elastic lamination 111 is in the shape of a frustum that can be folded along the first direction, and has a first end face 1111 and a second end face 1112. The orthographic projection of the first end face 1111 in the first direction is smaller than the orthographic projection of the second end face 1112 in the first direction.

[0048] Figure 1 It is shown in the schematic diagram of the state when the connection structure is not in use, that is, the state when the connection structure is not installed on the installation object 200. The second end face 1112 of each elastic lamination 111 is away from the pressing portion 12, and the first end face 1111 is close to the pressing portion 12.

[0049] Figure 2 It is shown in the schematic diagram of the state when the connection structure is in use, that is, the state when the connection structure is installed on the installation object 200. The elastic lamination 111 is folded towards the pressing portion 12 along the first direction, so that the second end face 1112 of each elastic lamination 111 is close to the pressing portion 12, and the first end face 1111 is away from the pressing portion 12.

[0050] The buckle portion 11 forms a fir tree structure. Before the connection structure is installed on the installation object 200, the first end face 1111 of the fir tree structure faces downwards, and the area of the first end face 1111 is smaller than the area of the second end face 1112; after the connection structure is installed on the installation object 200, the first end face 1111 of the fir tree structure faces upwards, that is, towards the pressing portion 12.

[0051] The buckle portion 11 that can be folded is not only convenient for installing it inside the installation object 200, but also can improve the clamping firmness between the buckle portion 11 and the installation object 200.

[0052] It can be understood that, as Figure 5As shown, after the clamping part 10 is installed on the installation object 200, the elastic lamella 111 of the buckle part 11 is folded, and the elastic lamella 111 will generate a restoring force to restore its original posture. The elastic lamella 111 corresponding to the installation hole of the installation object 200 abuts against the inner wall of the installation hole, and the restoring force of the elastic lamella 111 acts on the inner wall of the installation hole, which can improve the clamping firmness of the buckle part 11. In addition, the cooperation between the buckle part 11 and the pressing part 12 can further improve the connection firmness between the clamping part 10 and the installation object 200.

[0053] The clamping part 10 is injection-molded and has excellent toughness, which can further improve the clamping effect between the clamping part 10 and the installation object 200. Preferably, the steering part 20 and the clamping part 10 are integrally injection-molded to ensure structural stability.

[0054] In an alternative embodiment, as Figure 6 shown, each elastic lamella 111 includes a first lamella 11a and a second lamella 11b, and the first lamella 11a and the second lamella 11b are arranged at intervals. The spaced first lamella 11a and second lamella 11b can facilitate the folding of the elastic lamella 111. The distance between the first lamella 11a and the second lamella 11b is set according to factors such as the size and material of the elastic lamella 111, which is not limited in the embodiments of the present application. In addition, the elastic lamella 111 may further include a third lamella, a fourth lamella and more lamellas, which are set according to specific requirements and are not limited in the embodiments of the present application.

[0055] In an alternative embodiment, as Figure 2 shown, the end of the buckle part 11 away from the pressing part 12 has a convex column 112, and the surface of the convex column 112 is a curved surface structure. The convex column 112 with a curved surface structure facilitates the insertion of the clamping part into the installation hole of the installation object 200 and improves the installation efficiency.

[0056] In an alternative embodiment, the pressing part 12 is a conical suction cup structure. When the buckle part 11 is clamped in the installation hole of the installation object 200, the pressing part 12 adsorbs on the surface of the installation object 200. The pressing part 12 with a suction cup structure and the buckle part 11 with a fir tree structure can ensure the connection stability between the clamping part 10 and the installation object 200.

[0057] In an alternative embodiment, as Figure 1 and Figure 2 shown, the angle at which the steering part 20 moves along the first through hole 131 is 0-90°. It can be understood that the first through hole 131 is a 1 / 4 circle structure, and the steering part 20 can automatically adjust the angle under the action of force balance according to the position and posture of the wire harness.

[0058] Furthermore, the connection structure can rotate within the mounting hole of the mounting object 200, greatly increasing the adjustment range of the position and posture of the wire harness.

[0059] In an alternative embodiment, as Figure 7 shown, the steering member 20 is further provided with a third through hole 220 and a fourth through hole 230 that communicate with each other. The tightening member 30 is inserted into the third through hole 220 or the fourth through hole 230, and the third through hole 220 and the fourth through hole 230 are arranged staggeredly. The steering member 20 is provided with the staggeredly arranged third through hole 220 and fourth through hole 230, which can meet more adjustment requirements of the wire harness and improve the adaptability of the connection structure.

[0060] Furthermore, the third through hole 220 and the second through hole 210 are arranged in parallel at an interval, and the fourth through hole 230 and the second through hole 210 are arranged perpendicular to each other at an interval. In this way, while improving the adaptability of the connection structure, the stability of the structure of the steering member 20 can be ensured.

[0061] The embodiment of the present application also provides a battery pack, including the connection structure provided in any of the above embodiments; the battery pack further includes a wire harness and a mounting object 200, and the connection structure connects the wire harness to the mounting object 200. This connection structure can not only adjust the wire harness in multiple angles and directions, but also ensure the firmness of the connection between the clamping member 10 and the mounting object 200, further ensuring the stability of the relative position between the wire harness and the mounting object 200.

[0062] The embodiment of the present application also provides an electrical device, including the battery pack provided in the above embodiment. The connection structure can ensure the stability of the relative position between the wire harness and the mounting object 200, and thus can ensure the stability of the performance of the battery pack, further ensuring the stability of the application of the electrical device.

[0063] It should be understood that the above embodiments are all exemplary and do not cover all possible implementation manners included in the claims. Without departing from the scope of the present disclosure, various deformations and changes can be made based on the above embodiments. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form additional embodiments of the present application that may not be clearly described. Therefore, the above embodiments only represent several implementation manners of the present application and do not limit the protection scope of the patent of the present application.
