Fig. 1 is an assembled perspective view of an embodiment of a battery according to the present disclosure. Fig. 2 is an exploded view of fig. 1.
As shown in fig. 1 and 2, the battery 100 includes a case 1, electrode terminals 2, and a protective plate assembly 3.
The housing 1 comprises a first wall surface 11. The housing 1 is a hard shell housing, for example a metal housing. The housing 1 may be formed with a portion of the circumference including the first wall surface 11 as shown in the drawing and a portion of one side of the circumference on the upper and lower sides, and then assembled with a portion of the other side of the circumference on the upper and lower sides. Of course, the portion of the housing 1 including the first wall surface 11 may be used as a cover, and the other portion of the housing 1 may be a case with a bottom and an opening at one side, and the cover may be assembled to the opening. An electrode assembly (not shown) is housed in the case 1, and the electrode assembly is electrically connected to the electrode terminal 2. The electrode assembly is formed by laminating or winding a positive electrode tab, a negative electrode tab, and a separator.
The electrode terminal 2 has a first end face 21, and the first end face 21 is exposed on the first wall face 11. In some embodiments, as shown in fig. 2, the number of the electrode terminals 2 is two. In some embodiments, the electrode terminal 2 is one, the housing 1 is a conductive housing, and the electrical polarity of the housing 1 is opposite to that of the electrode terminal 2.
The protective plate assembly 3 includes a protective plate 31.
The protective plate 31 has a flat plate shape. The protective plate 31 has a first plate surface 311 and a second plate surface 312 opposite to each other in the thickness direction of the protective plate 31, the first plate surface 311 facing the first wall surface 11, the protective plate 31 being electrically connected to the first end surface 21 of the electrode terminal 2 at the first plate surface 311. The protection plate 31 also has a side surface 313 connected between the first plate surface 311 and the second plate surface 312 in the thickness direction of the protection plate 31. By the protection plate 31 being flat and the first plate surface 311 facing the first wall surface 11, the protection plate 31 lies flat on the first wall surface 11 of the casing 1, thereby saving space in the direction in which the first plate surface 311 and the first wall surface 11 face each other.
In some embodiments, the side 313 includes two opposite first sides 313a and two opposite second sides 313b, and the area of the first sides 313a is larger than that of the second sides 313 b.
The protective plate assembly 3 further comprises conductive terminals 32. The conductive terminals 32 are disposed on the side 313 of the protection plate 31, and the conductive terminals 32 are electrically connected to the protection plate 31. By disposing the conductive terminals 32 on the side 313 of the protection plate 31, the conductive terminals 32 disposed on the second plate surface 312 of the protection plate 31 are prevented from occupying the space of the battery 100 in the direction in which the first plate surface 311 and the first wall surface 11 face each other. The conductive terminals 32 are disposed on the side 313 of the protection plate 31, so that a sufficient space is left for disposing the required component E on the second plate surface 312 of the protection plate 31. In some embodiments, the conductive terminal 32 includes a cylindrical body 321 and two fins 322, the two fins 322 are combined with the side surface 313 of the protection plate 31, and two ends of the cylindrical body 321 are exposed out of the first plate surface 311 and the second plate surface 312 of the protection plate 31, respectively. The conductive terminals 32 with such a shape can be directly formed by a conductive via forming technique (e.g., plating) of a circuit board in the semiconductor field, such as forming the conductive via on a single substrate, dividing the conductive via into two parts along a center line, i.e., forming two protection plates, and certainly leaving a slit on two sides of the conductive via, thereby forming two fins 322. Thereby improving the production efficiency and the quality stability of the produced protective plate 31.
In some embodiments, the protective plate assembly 3 further comprises an electrical connection sheet 33. The electrical connection sheet 33 is disposed between the first end surface 21 and the first plate surface 311, and the electrical connection sheet 33 is used for electrically connecting the first terminal 2 and the protection plate 31. The electrical connection sheet 33 has a first surface 331 and a second surface 332 opposite to each other in the thickness direction of the electrical connection sheet 33, the first surface 331 of the electrical connection sheet 33 is in contact with and electrically connected to the first end surface 21 of the electrode terminal 2, and the second surface 332 of the electrical connection sheet 33 is in contact with the first plate surface 311 of the protection plate 31 and electrically connected to the protection plate 31. In some embodiments, the material of the electrical connection pad 33 is nickel. In some embodiments, the electrical connection sheet 33 is in a single-layer flat plate shape, thereby reducing the space occupied by the electrical connection sheet 33 in the direction in which the first plate surface 311 of the protective plate 31 and the first wall surface 11 of the housing 1 face each other. The number of the electrical connection sheets 33 corresponds to the number of the electrode terminals 2, and in some embodiments, as shown in fig. 2, the number of the electrical connection sheets 33 is two.
In some embodiments, the protective plate 31 is provided with a through hole 314. When viewed in the thickness direction of the circuit board, at least a part of the electrical connection sheet is positioned in the through hole, the through hole 314 penetrates the protection plate 31 along the thickness direction of the protection plate 31, and the second surface 332 of the electrical connection sheet 33 at least partially covers the through hole 314. After the electrical connection sheet 33 is positioned on the first end surface 21 of the electrode terminal 2 and the protective plate 31 is mounted, the electrical connection sheet 33 and the first end surface 21 of the electrode terminal 2 are laser-welded from the second plate surface 312 of the protective plate 31 via the through-hole 314, thereby improving the convenience of operation.
In some embodiments, the housing 1 is a conductive housing. The protection plate assembly 3 further includes an insulation sheet 34. The insulating sheet 34 is provided between the first wall surface 11 and the protective plate 31. The insulating sheet 34 has a flat plate shape. The insulating sheet 34 has opposite first and second outer surfaces 341 and 342 in the thickness direction of the insulating sheet 34. The first outer surface 341 of the insulating sheet 34 faces the first wall surface 11 of the casing 1, and the second outer surface 342 of the insulating sheet 34 faces the first plate surface 311 of the protective plate 31. The insulating sheet 34 has an opening 343, and the opening 343 penetrates the insulating sheet 34 in the thickness direction of the insulating sheet 34. The electrode terminal 2 protrudes the first wall surface 11 toward the first plate surface 311 of the protection plate 31. The electrode terminal 2 passes through the opening 343 of the insulation sheet 34. That is, the electrode terminal 2 is at least partially provided at the opening 343. The insulating sheet 34 electrically isolates the conductive case from the protective plate 31, thereby improving the safety in use. By making the insulating sheet 34 flat, the space occupied by the insulating sheet 34 in the direction in which the first plate surface 311 of the protective plate 31 and the first wall surface 11 of the case 1 face each other can be effectively controlled. In some embodiments, first outer surface 341 and second outer surface 342 are each entirely planar faces.
In some embodiments, the protection plate assembly 3 further includes an electronic component E disposed on the second plate surface 312 of the protection plate 31.

The description of the same parts as in the embodiment shown in fig. 1 to 2 is omitted.
The conductive connector 4 is soldered to the conductive terminal 32, and the conductive connector 4 is electrically connected to the protection plate 31 via the conductive terminal 32. The conductive connecting member 4 can increase the current passing capability of the conductive terminal 32 according to practical requirements. In the assembling process, the protection plate 31, the conductive terminals 32, the electrical connection sheet 33, and the insulation sheet 34 are assembled (for example, in the assembling state of fig. 1), and then the conductive connection members 4 are soldered to the conductive terminals 32.
In some embodiments, the conductive connection 4 comprises a first portion 41 and a second portion 42. The first portion 41 and the second portion 42 form an L-shape and are connected to each other. The first portion 41 faces the side 313 of the protective plate 31, abuts and is electrically connected to the conductive terminal 32; the second portion 42 faces the second plate 312 of the protection plate 31, and abuts and is electrically connected to the conductive terminal 32. The L-shaped conductive connecting piece 4 is adopted, so that the area of the conductive connecting piece 4 is increased, the overcurrent capacity is increased, and the mounting stability of the conductive connecting piece 4 on the conductive terminal 32 is improved. The conductive connecting pieces 4 comprise at least four conductive connecting pieces, and the four conductive connecting pieces 4 are respectively a positive conductive connecting piece, a negative conductive connecting piece, a grounding conductive connecting piece and a signal conductive connecting piece.
The insulator 5 is connected to the first wall surface 11. The insulator 5 has a first outer surface 51, the first outer surface 51 being opposed to the side 313 of the protective plate 31; the insulator 5 is joined to the first wall surface 11 of the case 1 in the normal direction of the first wall surface 11 of the case 1, the electrode terminal 2 and the protective plate assembly 3 are embedded in the insulator 5, and the material of the insulator 5 is provided in the gap between the electrode terminal 2 and the protective plate assembly 3 and the gap inside the protective plate assembly 3; the conductive connector 4 is exposed at the first outer surface 51 of the insulator 5 and embedded in the insulator 5. In other words, the insulator 5 embeds all the members of the protection board assembly 3 (specifically, the protection board 31, the conductive terminals 32, the electrical connection sheets 33, the insulation sheets 34), the electrode terminals 2, and a part of the conductive connection members 4 and fills gaps therebetween. Accordingly, no member is exposed except for the portion of the conductive connector 4 exposed from the first outer surface 51 of the insulator 5, and the insulator 5 is bonded to the first wall surface 11 of the case 1, whereby the insulation and sealing properties are improved, and the strength of these members against external impact is also improved. In the assembling process, after the protective plate 31, the conductive terminals 32, the electrical connection sheet 33, the insulating sheet 34, and the conductive connection member 4 are assembled, the insulator 5 is molded by injection molding. That is, the insulator 34 is formed by applying an insulating material to the periphery of the electrode terminal 2 and the protective plate assembly 3 and then curing the same.
