[0044] In existing battery boxes, function keys are electrically connected to the PBCA (Printed Circuit Board Assembly) via ejector pins. The box body has a mounting hole for the ejector pin to pass through and a seal disposed in the mounting hole. In the existing structure, the seal is supported by the inner wall of the positioning hole, resulting in significant structural interference between the ejector pin and the seal. During assembly of the battery box, the ejector pin is subjected to a relatively hard squeezing force in the mounting hole, causing the ejector pin to become skewed, affecting the structural reliability, waterproofness, and airtightness.
[0045] Based on this, in order to solve the above problems, the present application designs a battery box, which achieves a waterproof sealing effect through interference fit between the extension part and the electrical connector. The extension part extends out of the via hole, and the extension part does not contact the inner wall of the via hole. The extension part has little interference with the structure of the electrical connector; when the electrical connector is subjected to force, the extension part will not generate a harder extrusion force with the electrical connector, and the extension part can achieve a better sealing effect.
