Abstract

The utility model discloses a novel button cell which comprises a round body and lugs, wherein the round body is composed of an anode cover and a cathode cover; an inner cavity is formed in the round body; electrolyte is contained in the inner cavity; an anode groove and a cathode groove for accommodating the plugs are formed at the positions for welding the lugs on the outer surface of the anode cover and the outer surface of the cathode cover respectively; an insulating material is arranged at the position of the plug close to a rubber ring of the button cell; the anode groove passes through the center of the outer surface of the anode cover and penetrates through the anode cover; the cathode groove deviates from the center position of the outer surface of the cathode cover; and the cathode groove is a half-closed groove. In a welding process of the cell, the two processes of cutting the insulating material and wrapping the cell to go through a drying channel can be saved, and the two-station cost and the cost of removing the insulating material are reduced at the same time; the cell has the advantage that the total thickness of the product is greatly reduced; and the thickness of the product processed by the method is equivalent to the thickness of a naked cell only.

Description

A kind of novel button cell

Technical field

The utility model relates to button cell field, especially relates to coming and the lithium-manganese cell of ear, comprises the lug that is arranged at the lug groove of positive cover outer surface and cathode cover exterior face and one end and is provided with insulating material.

background technology

The button cell in the past using is to be all directly placed on the parts of required power supply, when parts transport or transfer, battery obscission may occur so, will cause the use of whole parts like this.

For above problem, general li-Mn button cell, in order to be welded on pcb board or other electronic devices and components, all adopts battery plus-negative plate soldering polar ear mode.

As Chinese patent discloses the patent that a kind of notification number is 202905844U: button cell, its technical scheme is: a kind of button cell, comprise circular body, two surfaces of described body are respectively provided with a leg, leg is comprised of stiff end and welding ends, welding ends is positioned at the top of stiff end, and stiff end is fixedly connected on body, and the outward extending direction of welding ends of two legs is identical; Described stiff end and welding ends are structure as a whole; The width of described stiff end is greater than the width of welding ends.It is fastening that this technology makes battery be connected with external component, and difficult drop-off has improved the service efficiency of whole parts.

But this welding manner, often relates to gross thickness problem after welding battery.Battery gross thickness is determined by plain battery, insulating material and lug three thickness.

On the market in order to reduce the rear gross thickness of welding, the method for employing is to remove insulating material or reduce lug thickness at present.But still cannot meet some special thickness requirements after sometimes adopting these methods.

Utility model content

Technical problem to be solved in the utility model is: overcome after above welding battery and when gross thickness is excessive, will remove insulating material or to reduce lug thickness and cause meeting the problem that some special thickness require.

For above technical problem, the utility model proposes technical scheme and be: a kind of novel button cell, comprise circular body and lug, described circular body consists of positive cover and negative cover, and this circular body has an internal cavity, and this internal cavity is built-in with electrolyte;

Described positive cover outer surface and cathode cover exterior face need the position of soldering polar ear to be respectively arranged with to lay anodal groove and the negative pole groove of this lug; Described lug approaches this button cell cushion rubber position and is provided with insulating material.

Preferably, described anodal groove passes the center of circle of described positive cover outer surface and runs through described positive cover.

Preferably, described negative pole groove is a semi-enclosed groove the home position that departs from described cathode cover exterior face.

Preferably, described anodal groove and negative pole groove are vertically installed in polar cap outer surface separately.

Preferably, described insulating material is insulating cement.

The beneficial effects of the utility model are: battery in welding procedure, can reduce cut insulating material, parcel battery is crossed drying tunnel two-step, reduced by two station costs simultaneously and removed the cost of insulating material; The utility model great advantage is to greatly reduce product gross thickness; The product thickness processing by the method is equivalent to only have plain battery thickness.

Embodiment

Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of novel button cell of the utility model is described further, but should limit protection range of the present utility model with this.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of novel button cell of the utility model, comprises circular body 1 and lug 4, and described circular body 1 consists of positive cover 2 and negative cover 3, and this circular body 1 has an internal cavity, and this internal cavity is built-in with electrolyte;

Described positive cover 2 outer surfaces and negative cover 3 outer surfaces need the position of soldering polar ear 4 to be respectively arranged with to lay anodal groove 21 and the negative pole groove 31 of this lug 4; Two its degree of depth of groove of described this can suitably be adjusted according to battery performance or lug 4 thickness; Width can put down a little a little louder lug than lug 4 and be advisable, and this size can make the appropriate adjustments according to lug 4 width.By this point, can reduce or remove the thickness that lug 4 produces on product.

Described anodal groove 21 passes the center of circle of described positive cover 2 outer surfaces and runs through described positive cover 2.

Described negative pole groove 31 departs from the home position of described negative cover 3 outer surfaces; Described negative pole groove 31 is a semi-enclosed groove.The blind end of this negative pole groove 31 ends at a diameter of the negative cover vertical with this negative pole groove 31 3; Certainly, as improved words, be not limited to this, this negative pole groove 31 can also considerably extend according to requirements.

As shown in Figure 2, anodal groove 21 and negative pole groove 31 are vertically installed in polar cap outer surface separately; This is a kind of preferred mode, the certain distribution that can make according to the actual requirements other angles.

As shown in Figure 5, described lug 4 comprises stiff end 43, insulating barrier coated end 42 and welding ends 41.The insulating material that the insulating barrier coated end 42 of described lug 4 arranges is fixed on described lug 4 by the mode of pasting or spray; Described insulating material is insulating cement.

It installs principle: lug 4 is arranged in anodal groove 21 and negative pole groove 31, and at lug 4, approaches this button cell cushion rubber position insulating material is set, and does like this and just can greatly reduce product gross thickness.

The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection range of claim of the present utility model.In addition,, although used some specific terms in this specification, the use of these terms, does not form any restriction to the utility model.
