Abstract: A chip slot is disclosed, which includes a slot, where a plurality of terminal groups are disposed in the slot, terminals in each terminal group include metal sheets that are symmetrically disposed on two opposite inner side walls of the slot, and each metal sheet has a bending pin that extends outside the slot; bending directions of bending pins on the terminals in each terminal group are same; and for any row of metal sheets in any two adjacent terminal groups, along an arrangement direction of the row of metal sheets, bending pins of the metal sheets in the adjacent terminal groups are alternately arranged on both sides of the row of metal sheets. The bending pins of the row of metal sheets are bent toward two different directions.

Abstract: A lead-acid battery includes a container and an intermediate cover. The container comprises six pole groups in linear arrangement in a longitudinal direction. Two of the pole groups on a farthest edge are provided with pole posts penetrating through the intermediate cover. The intermediate cover is fixed with two connection terminals. Each of the connection terminals comprise a first connecting part connected to the pole post and a second connecting part connected to an external wire. The two connection terminals are provided on a side of the intermediate cover in a width direction of thereof, and the second connecting part is led out from a side surface of the intermediate cover. One of the connection terminals is directly connected to one of the pole posts, and the other one of the connection terminals is connected to another one of the pole posts via an adapted cable.
