Specifically, the wire-clamping structure 22 may include a first wire-clamping part 221 and a second wire-clamping part 222 disposed on two opposite sides of the wire hole 21; the gap between the first elastic arm 221 and the second elastic arm 222 may be gradually increased towards the edge of the partition 20, that is, the two can form a contraction structure. The first elastic arm 221 and the second elastic arm 222 each have a fixed end and a free end. The fixed end of both is connected to the edge of the partition 20, and the free end faces the end of the wire hole 21 away from the edge of the partition. Through the cooperation of the first elastic arm 221 and the second elastic arm 222, the connecting wire (not shown) can be prevented from coming out from the side of the partition 20. In some other embodiments, a fixing member may be provided on the outer periphery of the connecting wire (not shown), and a slot may be provided on the fixing member. The slot can be engaged and fixed with the edge of the wire hole 21, thereby preventing the connecting wire (not shown) from being pulled out excessively and avoiding disconnection from the motherboard 80, thereby improving the stability of the connection and its service life.

Specifically, the snap-fit ​​structure may include a buckle 61 and a snap hole 19, wherein the buckle 61 may be disposed on at least one side of the grille plate, and the snap hole 19 may be disposed on the side wall or end wall of the housing 10 and correspond one-to-one with the buckle 61. When the grille plate 60 is installed with the housing 10, the buckle 61 of the grille plate 60 can be snapped into the corresponding snap hole 19. In some embodiments, the grille plate 60 may be a different color from the housing 10, thereby serving a color matching function and making the entire battery charger more aesthetically pleasing.

[0067] For example Figure 6 and Figure 7 As shown, in some embodiments, the battery charger further includes a wire clip 90, which can be disposed in the wire hole 21 for fixing the connecting wire (not shown). Specifically, there can be two wire clips 90, each wire clip 90 can be disposed in the wire hole 21 and can be snapped into the inner wall of the wire hole 21. Each wire clip 90 has a wire-holding groove 91 facing the wire-holding structure 22, which allows the connecting wire (not shown) to be inserted to prevent the connecting wire (not shown) from falling out. One wire clip 90 can be used for installing an AC wire, and the other wire clip 90 can be used for installing a DC wire. In some embodiments, the wire clip 90 can be omitted.

[0068] During assembly of the battery charger, the partition 20 can be inserted into the first mounting slot 116 of the first housing 11, the display device 40 can be slid into the first sliding groove 118 and installed at the second notch 113 of the first housing 11, and the exhaust fan 50 can be installed at the fourth notch 125 of the first housing 11; then the main board 80 can be placed into the first cavity 101a, and the connecting wires (not shown) can be placed into the second cavity 101b. One of the connecting wires (not shown) can be passed through one of the wire holes 21, secured by the wire clip 90 and the wire clamping structure 22, and connected to the main board 80. The other connecting wire (not shown) can be passed through another wire hole 21, secured by the wire clip 90 and the wire clamping structure 22. The wire-clamping structure 22 is fixed and connected to the motherboard 80; then the second mounting slot 126 of the second housing 12 is fitted onto the partition 20 for positioning, the display device 40 is slidably inserted into the second sliding groove 1210, the sixth notch 123 of the second housing 12 is opposite to the second notch 113 of the first housing 11, the second housing 12 is pushed toward the first housing 11 until the edge of the second opening 121 of the second housing 12 is connected to the edge of the first opening 111 of the first housing 11, and finally the screw is inserted through the screw mounting hole 11g to fix the first housing 11 and the second housing 12, and the cover plate 30 is inserted into the second slot 127 and the first slot 117.
