Based on the winding type battery of lithium ion battery, Ni-MH battery etc., mobile products such as MP3, MP4, personal digital assistant, mobile phone, digital camera, electric tool, toy have been widely used in.With the rectangular cell is example, comprise cover plate, end square tube shape battery case is arranged and be contained in described battery case inside by the battery unit of described cover plate for sealing, electrolyte; As shown in Figure 1, battery unit comprises the positive and negative plate and the barrier film of overlapping coiling, barrier film separates both between positive and negative plate, the positive and negative electrode active material that described positive and negative plate comprises the positive and negative electrode collector and is coated in positive and negative electrode collector two sides, described first lug 1 ', second lug are drawn from positive and negative collector/negative positive collector respectively.Wherein first lug 1 ' is electrically connected on the conducting terminal on the cover plate; Second lug 4 comprises collector connecting portion 9 ' and straight extension stem 8 ', and collector connecting portion 9 ' is riveted on the collector 5 ', and straight extension stem 8 ' is welded on the housing.The deficiency that this kind structure exists is: because battery unit can rock in battery case, when battery falls or be subjected to foreign impacts, often there will be two kinds of situations: a, straight extension stem 8 ' come off with the welding of battery inwall, cause the inside battery internal resistance of cell to increase even open circuit; B, connecting portion 9 ' is with the collector fracture or tear, and causes internal resistance to increase even opens circuit.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned the deficiencies in the prior art, and the more stable battery of electrical connection properties between a kind of lug and pole piece, the housing is provided.
Realize the technical scheme of above-mentioned purpose: a kind of winding type battery, comprise cover plate, the bottomless drum shape battery case is arranged, and be contained in described battery case inside by the battery unit of described cover plate for sealing, electrolyte, battery unit is just comprising overlapping coiling, negative plate, barrier film, positive pole ear and negative lug, barrier film just is positioned at, between the negative plate both are separated, one end of positive pole ear connects positive plate, one end of negative lug connects negative plate, the other end of one of them lug is electrically connected on the conducting terminal on the cover plate, the other end of another lug is welded in cover plate and sews on being connected of battery case, the described cover plate that is connected is connected with positive plate or negative plate outermost external surface with an end of the lug of sewing on being connected of battery case, the interlude of this lug is forniciform fragment, described forniciform fragment is returned a crooked segment distance to combining between cover plate and the battery unit upper surface after a crooked segment distance is located in the slit again, and the other end of this lug is fixed on company's seam crossing of internal surface of battery shell and cover plate.
The described cover plate that is connected is connected with positive plate or negative plate outermost external surface by the riveted joint mode with an end of the lug of sewing on being connected of battery case.
Further, between cover plate and battery unit, insulation board is set.Be provided with insulating tape with the contacted battery unit of forniciform lug surface.
Further, on described forniciform lug, be arranged with insulating case.
Further, described battery is a lithium ion battery.
Adopt technique scheme, beneficial technical effects of the present invention is: 1, by a forniciform fragment being set connecting pole piece and internal surface of battery shell or be connected on cover plate and the lug of sewing on being connected of battery case, even when battery is given a shock or impact, changed the direction of propagation of power by forniciform fragment, the sweep that vibrations that battery is subjected to or impulsive force major part are transferred between cover plate and the battery unit bears, thereby, the vibrations that battery is subjected to or the major part of impulsive force can not be directly delivered to another pad (lug is with internal surface of battery shell or be connected cover plate and the pad of the pad of company's seam crossing of battery case or lug and pole piece) from a pad (pad of lug and pole piece or lug and internal surface of battery shell or be connected the pad of cover plate and company's seam crossing of battery case), alleviated impulsive force greatly, prevented that battery inwall welding from coming off and with the fracture of collector tie point or tear and the generation of open circuit conditions pad.2, by insulating tape being set or on forniciform lug, being arranged with insulating case, effectively avoid causing the generation of contact short-circuit conditions because of forniciform lug with the contacted battery unit of forniciform lug surface.3,, further avoided cover plate to cause the possibility of battery unit short circuit by between cover plate and battery unit, insulation board being set.
