Abstract
The utility model provides a low-cost, mercury-free and anti-air expansion button cell, which comprises a positive electrode shell, a diaphragm, a positive electrode manganese sheet, a sealing rubber ring, negative electrode zinc paste, a negative electrode cover and an alloy plating layer, wherein the alloy plating layer is made of one of three alloys of indium-zinc alloy, indium-tin alloy or indium-zinc-tin alloy; the diaphragm is attached to the inner surface of the positive electrode shell; the positive electrode manganese sheet, the sealing rubber ring and the negative electrode zinc paste are all positioned in the positive electrode shell; the positive electrode manganese sheet is arranged below the sealing rubber ring; the positive electrode shell is connected with both the positive electrode manganese sheet and the sealing rubber ring in an embedding mode; the sealing rubber ring is embedded with the negative electrode zinc paste by using a pouring and solidification method; the negative electrode cover covers the positive electrode shell, the outer peripheral surface and the inner side face of the negative electrode cover are connected with the inner peripheral surface of the sealing rubber ring and the negative electrode zinc paste in the embedding mode respectively; and the alloy plating layer is plated on the inner side face of the negative electrode cover. After the scheme is adopted, the button cell has the beneficial effects of preventing air expansion and protecting environment, along with low cost.
Description
Technical field
The utility model relates to the technical field of button cell, refers in particular to the button cell that the no mercury gas-tight of a kind of low cost rises.
Background technology
Present zinc-manganese electricity core battery, contain the composition of zinc because of negative pole, so must add mercury, in order to prevent that zinc and other raw materials or Metal Contact from causing producing gas and make cell expansion, and contain mercury in the battery, be commonly called as " mercury ", mercury is difficult to degraded again, so discarded battery can inevitably cause very serious pollution to environment; No exception with regard to button cell.Along with the continuous enhancing of environmental consciousness, for guaranteeing continuous development of society economy, no matter from domestic still international, battery is mercuryless all extremely urgent.As the mercuryless instruction of the battery of the RoHS of European Union in enforcement on June 1 in 2006.The mercury-free battery technology is also day by day ripe under trend of the times, but also there are some problems in the mercury-free battery of present stage: 1) electroplating cost height; 2) the battery gas rate that rises is higher.The rate though the gas that has reduced battery as the patent of the patent No. 01234722.1 and the patent No. 200620123203.0 rises, because the coated metal composition, the variable thickness sample that use, so that the cost of electroplating is still higher.The utility model is exactly on the basis of conscientious and sufficient investigation, understanding, analysis, the above-mentioned existing known technology of summary and present situation, for overcoming and solving that the deficiency, defective and the drawback that exist in existing known technology and the real current situation succeed in developing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and reasonable, cost is low, no mercury gas-tight rises button cell is provided.
For achieving the above object, technical scheme provided by the utility model is: the button cell that the no mercury gas-tight of a kind of low cost rises, it includes anodal shell, barrier film, anodal manganese sheet, O-ring seal, negative zinc cream, negative cover, wherein, it also includes by one of indium zinc, indium tin or three kinds of alloys of indium zinc-tin made alloy plated layer, wherein, barrier film is attached on the inner surface of anodal shell; Anodal manganese sheet, O-ring seal and negative zinc cream all are positioned at anodal shell, and anodal manganese sheet places the below of O-ring seal; Anodal shell all is connected in the mode of inlaying with O-ring seal with anodal manganese sheet, and O-ring seal adopts the mode of irritating the cream after coagulation to be embedded in negative zinc cream; Negative cover is covered on anodal shell, and its peripheral surface and medial surface enclose face and are connected in the mode of inlaying with negative zinc cream respectively with in the O-ring seal, and are electroplate with alloy plated layer on the medial surface of negative cover.
Described O-ring seal is the circular seal round.
The utility model is after having adopted such scheme; its great advantage is the utility model by adopting by one of indium zinc, indium tin or three kinds of alloys of indium zinc-tin made alloy plated layer, makes the utility model obtain to prevent that gas from rising, protecting environment to reach beneficial effect cheaply.

Fig. 2 is the structural representation after alloy plated layer is gone up in negative cover plating of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: the button cell that the no mercury gas-tight of the described a kind of low cost of present embodiment rises, it includes anodal shell 1, barrier film 2, anodal manganese sheet 3, O-ring seal 4, negative zinc cream 5, negative cover 6, wherein, the utility model also includes by one of indium zinc, indium tin or three kinds of alloys of indium zinc-tin made alloy plated layer 7, and the structure of O-ring seal 4 of the present utility model is circular seal rounds, and barrier film 2 is attached on the inner surface of anodal shell 1; Anodal manganese sheet 3, O-ring seal 4 and negative zinc cream 5 all are positioned at anodal shell 1, and anodal manganese sheet 3 places the below of O-ring seal 4; Anodal shell 1 all is connected in the mode of inlaying with O-ring seal 4 with anodal manganese sheet 3, and O-ring seal 4 adopts the mode of irritating the cream after coagulation to be embedded in negative zinc cream 5; Negative cover 6 is covered on anodal shell 1, and its peripheral surface and medial surface enclose face and are connected in the mode of inlaying with negative zinc cream 5 respectively with in the O-ring seal 4, and are electroplate with alloy plated layer 7 on the medial surface of negative cover 6.Because the utility model adopted by one of indium zinc, indium tin or three kinds of alloys of indium zinc-tin made alloy plated layer 7, make the utility model reach not produce that gas rises and free from environmental pollution, also can reduce the purpose of battery production cost simultaneously.The utility model has solved the problems of traditional button cell preferably like this, is worthy to be popularized.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection range of the present utility model.
