Description

Technical Field

[0001] The utility model relates to the field of batteries and technologies, in particular to an electrical connection docking structure of a battery box. Background Art

[0002] In the current battery box and controller connection technology, the correct pairing and stable connection of the connector is one of the key factors to ensure the reliable operation of the equipment. Traditionally, the electrical connection between the battery box and the controller mostly relies on the standard male and female connector design, which is generally applicable and easy to produce, but has some shortcomings in practical applications.

[0003] First, during the process of assembling the male connector to the controller, due to the lack of an effective fool-proof design, the operator may mistakenly try to install it in reverse, which will not only lead to connection failure, but may also cause unnecessary damage to the connector or controller interface, affecting the service life and safety of the product.

[0004] Secondly, even if the forward installation is successful, some existing male and female connector designs are often relatively basic in structure and lack sufficient mechanical stability. After vibration, impact or long-term use, the connection may become loose or have poor contact, which directly affects the continuity and efficiency of power transmission. For application scenarios that require highly stable power supply (such as power tools, electric vehicles, energy storage systems, etc.), such instability is unacceptable. Utility Model Content
