Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Examples

The battery box of the electric bone saw shown in fig. 1 comprises a shell 10 and a battery pack positioned in the shell 10, wherein a first metal elastic sheet 20 belonging to a positive electrode and a second metal elastic sheet 30 belonging to a negative electrode are arranged at the top of the battery pack, and the first metal elastic sheet and the second metal elastic sheet are electrically connected through an electric connection sheet 40. Referring to fig. 3, one side of the electrical connection sheet 40 is provided with an electrical connection post 50, a bolt 60 outside the housing 10 passes through the housing 10 and is locked into the electrical connection post 50, the metal elastic sheet is sleeved on the electrical connection post 50, and the head of the bolt 60 presses the metal elastic sheet on the electrical connection post 50. The bottom of the electrical connection sheet 40 is inserted into the first metal spring sheet. The electric connection sheet and the electric connection column enable the first metal elastic sheet and the second metal elastic sheet to be electrically connected. The other side of the electric connection sheet 40 is provided with a notch 41, the casing is provided with an extended hook 11 corresponding to the notch 41, the hook part of the hook extends into the notch to hook the electric connection sheet, the freedom degree of the electric connection sheet in the vertical direction is limited, the electric connection sheet is prevented from moving up and down, and the electric connection sheet can be firmly fixed in the casing of the battery box after the bolt is locked.

Referring to fig. 2, a slot into which the top end of the electrical connection sheet 40 is inserted is formed in the inner wall of the housing 10, and the top end of the electrical connection sheet is inserted into the slot to achieve initial positioning. The hook 11 is pressed into the recess 41 of the electrical connection sheet by pressing the electrical connection sheet or housing slightly hard.

Referring to fig. 2, the inner side of the housing 10 is provided with a post 12 having a receptacle, and the electrical connection post 50 is inserted into the receptacle of the post to be fixed. The electrical connection post 50 is provided with a sealing ring 70 abutting against the end surface of the post 12 for ensuring the waterproof and dustproof performance of the battery box.

Referring to fig. 2, the hook portion of the hook 11 is provided with an arc surface 111 relative to one end of the housing 10, and during the process of mounting the electrical connection sheet, the inclined surfaces of the electrical connection sheet are tangentially connected, so that the hook can enter the notch 41 of the electrical connection sheet.
