Description

Technical Field

[0001] The utility model relates to the technical field of energy storage connection, in particular to an energy storage connector. Background Art

[0002] At present, the energy storage connectors in the prior art have many deficiencies in terms of stress, loss and safety performance, including the following three points: 1. The energy storage connectors in the prior art use crimped cables for connection, and the cable has high hardness. If a U-shaped connection is used between different layers of PACKs, the turning radius is large, and the entire cable needs to withstand greater stress after bending, and the cable is prone to cracking. If an up-and-down connection is used, the cable becomes shorter, resulting in difficulty in plugging and unplugging a single connector plug; 2. The energy storage connectors in the prior art are limited by the structure, and the cables are relatively long, resulting in high resistance and loss; 3. The energy storage connectors in the prior art only include a primary lock, which is difficult to maintain structural integrity under mechanical stress (such as vibration and impact), and has low safety performance.

[0036] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0037] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
