Summary of the invention
The invention provides a kind of square Ni-MH battery, it not only optimizes the inside battery structure, has saved battery space, has effectively reduced the internal resistance of cell, and can improve the reliability that battery combination connects.
The present invention has adopted following technical scheme: a kind of rectangular cell, it comprises housing, top at housing is provided with safety valve, in housing, be provided with pole piece and lug, the both positive and negative polarity of pole piece is connected with negative terminal with the anode of lug respectively, the other end of lug anode and the other end of negative terminal are connected with positive terminal and negative terminal respectively, and described positive terminal and negative terminal are set to horizontal pole, and positive terminal and negative terminal are that level is connected with the anode of lug with negative terminal respectively.
One side of described positive terminal and a side of negative terminal are baffler, on baffler, be provided with the lug groove, the anode of lug and negative terminal are installed in respectively in the lug groove of positive terminal and negative terminal fixedlys connected with negative terminal with positive terminal, the opposite side of positive terminal and the opposite side of negative terminal are the wiring column cap, and wiring column cap level is passed the side of housing and stretched out outside the housing.Described wiring column cap is cylinder or cube.Be connected for argon arc welding, Laser Welding, plasma welding or electron beam welding between the positive and negative end of described lug and positive terminal and the negative terminal.Described positive terminal and negative terminal are steel nickel plating material.Described positive terminal and negative terminal are copper, aluminium or iron.Described housing is a metal shell, and metal shell is stainless steel or iron nickel plating.Described housing is a non-metal shell, and non-metal shell is plastics or organic material.
The present invention has following beneficial effect: positive terminal of the present invention and negative terminal are set to horizontal pole, positive terminal and negative terminal respectively with lug just, negative terminal is that level connects, one side of positive terminal and negative terminal is a baffler, opposite side is the wiring column cap, wiring column cap level is passed the side of housing and is stretched out outside the housing, electric current can be conducted to outside batteries from the side like this, battery both can adopt the horizontally-arranged mode to connect when making up, also can adopt vertical row's mode to connect, so not only improved the inside battery structure, saved battery space, effectively reduced the internal resistance of cell, and can improve insulation property between assembled battery, and improve the reliability that battery combination connects, reduced the connection resistance between battery effectively.
