As shown in Figure 2, said retaining piece 50 reaches battery cover plate 30, conducting terminal 10, battery core cap lug 41,42 machineries to link together electrically.In the present embodiment, said retaining piece 50 is a rivet, and said conducting terminal 10, battery cover plate 30, battery core cap lug 41,42 and insulation cushion 70 are retained on together through rivet.The material of rivet is mainly aluminium, also can be the material of red metal or other equal performances.Said rivet 50 be shaped as round column, have the head of similar ladder type, be positioned at the below of battery cover plate 30 than major part.Said rivet 50 is of a size of: head width can be 7 ~ 10 millimeters, and thickness can be 0.8 ~ 1.5 millimeter, and bar directly can be 3.5 ~ 5 millimeters, and height is done corresponding adjustment according to the size of battery cover plate 30.The hole wall of four riveted holes on conducting terminal 10 installation portions 12 all coats with insulation cushion 70, rivet 50 is passed rivet again.In the present embodiment, utilize riveted joint mode fixed conductive terminals 10, insulation cushion 70, battery cover plate 30 and battery core cap lug 41,42.
Said insulating trip 60 is an insulator, and its material can be plastics.Said insulating trip 60 be shaped as a sheet insulator, can be squarely, marks the twice square aperture in the middle of the lamellar body, pass this insulating trip 60 in order to battery core cap lug 41,42.The effect of said insulating trip 60 is to avoid cell core lug 21,22 to touch battery cover plate 30 with the part that battery core cap lug 41,42 is connected.
Like Fig. 6 and shown in Figure 7, said insulation cushion 70 comprises first insulation division 71 in order to electric insulation conducting terminal 10 and battery cover plate 30 that is positioned at battery cover plate 30 1 sides, be positioned at battery cover plate 30 opposite sides is used for second insulation division 72 of electric insulation battery cover plate 30 and battery core cap lug 41,42 and is positioned at the connecting portion (figure does not show) that is connected first insulation division 71 and second insulation division 72 and electric insulation retaining piece 50 and battery cover plate 30.Said first insulation division 71 partly is coated on battery cover plate 30 tops; Said second insulation division 72 partly is coated on battery cover plate 30 belows; On the said connecting portion clad battery core cover plate 30 lid hole inwalls, said lid hole is to make rivet 50 can pass battery cover plate 30.The material of said insulation cushion 70 is PP (polypropylene), also can be the material of other insulation and electrolyte resistance corrosion, does not enumerate one by one in this.Said insulation cushion 70 has the I shape section shape.Overlook on the direction to being square, and four end fillets.Be appreciated that ground, said insulation cushion 70 areas must be bigger than the area of conducting terminal 10 installation portions 12, and also the area than battery core cap lug 41,42 is big, overlooks and also can be other shapes on the direction.The processing method of said insulation cushion 70 is that battery cover plate 30 is inserted injection molding machine earlier, makes the insulation system that cross section is an I shape with the mode of ejection formation then.Because conducting terminal 10, battery cover plate 30, cell core lug 21,22 reach battery core cap lug 41,42 and are metal material, so the purposes of said insulation cushion 70 is for avoiding the both positive and negative polarity short circuit.Particularly, said insulation cushion 70 be used for isolating simultaneously battery cover plate 30 and rivet 50, isolate battery cover plate 30 and battery core cap lug 41,42, being electrically connected between isolation battery cover plate 30 and the conducting terminal 10.In the utility model, said insulating trip 60 constitutes double-layer insulating structure with insulation cushion 70, makes that the insulation effect of battery is better.
The manufacturing approach of said battery cap assemblies 300 may further comprise the steps:
Injection mo(u)lding insulation cushion 70 on battery cover plate 30;
Conducting terminal 10 is provided, conducting terminal 10 is placed battery cover plate 30 1 sides;
Battery core cap lug 41,42 is provided, battery core cap lug 41,42 is placed battery cover plate 30 opposite sides;
Retaining piece 50 is provided, said retaining piece 50 with battery cover plate 30, insulation cushion 70, conducting terminal 10 and battery cover lug 41,42 machineries and electrically fixing link together;
With said battery core cap lug 41,42 and cell core lug 21,22 with the mode machinery of ultrasonic bonding and be electrically connected.
In above step, said conducting terminal 10, battery core cap lug 41,42 and retaining piece 50 all insulate with battery cover plate 30 through insulation cushion 70 mutually.Said cell core lug 21,22 is to use the supersonic welding mode that both welding are dissolved in the machinery and the electric connection of battery core cap lug 41,42.
As shown in Figure 8; Before welding battery core cap lug and the cell core lug; Second connecting portion 411,421 with battery core cap lug is riveted on the battery cover plate 30 earlier, makes second connecting portion 411,421 vertical with second joint portion 412,422 bending of battery core cap lug again.Simultaneously, make the angle of the win connecting portion 211,221 and first joint portion 212,222 also be 90 degree battery core cap lug also bending, also promptly vertical each other.Then, battery core cap lug is corresponding in twos according to positive and negative electrode with cell core lug.Then, with the supersonic welding mode both are welded in one.At last, battery cover plate 30 upset is made after fixing said cell core lug 21,22 roughly be the M font with cross section after battery core cap lug 41,42 is connected, as shown in Figure 6, also i.e. formation M font lug syndeton at last.
In the utility model, battery cap assemblies 300 uses the fixed form of riveted joint, can avoid producing the loosening phenomenon of similar screw, and can avoid the possibility of battery leakage, and overall structure is able to simplify.In addition, the utility model battery cap assemblies avoids the respond well while of short circuit can realize a large amount of productions.In addition, cell core lug 21,22 and battery core cap lug 41,42 adopt the connected mode and the recessed M font that is converted into of ultrasonic bonding, thereby can save space and firm welding.
