Abstract
The utility model relates to a circuit protection element. The circuit protection element for the rechargeable battery, battery group and other circuit of the utility model comprises a metal piece and a fuse, and is characterized in that the circuit protection element is connected with two bonding pads of a printed circuit board (PCB) through more than one metal fuse, and two metal pieces are connected with two bonding pad ends of the printed circuit board respectively.
Description
A kind of circuit protecting element is specially adapted to rechargeable battery, in the battery pack.
At present, be widely used in rechargeable battery, the circuit protecting element of battery pack is made with PTC, and its cost is higher.Disclose a kind of circuit protection unit among the Chinese patent CN1129857A, this circuit protection device is formed in parallel by a thermoswitch and a bypass heating resistor, and its structure is complicated and cost is higher; Disclosed another kind of circuit protection device among the Chinese patent CN2417622Y, though simple in structure, structure is insecure, and is fragile.
The purpose of this utility model provide a kind of simple in structure and firm, cost is low, the circuit protecting element very easily realized.Can be used for rechargeable battery. in battery pack and other circuit, the protection electronic equipment.
The purpose of this utility model is achieved by the following technical solution: the circuit protecting element of rechargeable battery, battery pack and other circuit; form by sheet metal and fusible link; it is characterized in that described circuit protecting element is connected by the Metal Melting fracture of wire more than between two pads of a wiring board (PCB), two metal sheets is connected to two pad ends of wiring board.
The purpose of this utility model can be achieved by the following technical solution equally: the circuit protecting element of rechargeable battery of the present utility model, battery pack and other circuit; form by sheet metal and fusible link; it is characterized in that being printed with between two pads of described circuit protecting element by a wiring board (PCB) circuit more than, two metal sheets is connected to two pad ends of wiring board.
The utility model can also cover an insulating barrier in described circuit protecting element.
That the utility model compared with prior art has is simple in structure and firm, cost is low, advantage such as realization very easily.
Description of drawings of the present utility model is as follows:
Fig. 1 is the schematic diagram of circuit protecting element of the present utility model.
Fig. 2 is that the utility model is applied in the schematic diagram in a kind of cordless telephone battery pack.
Below in conjunction with the full and accurate description the utility model of accompanying drawing: as shown in Figure 1; get a wiring board 1 that is of a size of 4 * 10 (mm); the pad size at wiring board two ends is 3.5 * 2.5 (mm); between two pads of wiring board, the burn-on copper wire 2 of Ф 0.10 * 10 (mm); weld size is 12.5 * 3 * 0.2 (mm) nickel sheet 3 respectively on the pad of wiring board two ends; and then cover insulating barrier 4 in the above, promptly produce circuit protecting element 5 of the present utility model.The utility model also in the circuit board printed wiring replace the copper wire of above-mentioned welding as wire.
As shown in Figure 2, circuit protecting element 5 is connected between rechargeable battery B1 and the B2, forms rechargeable battery pack.When batteries charging or discharging current reach about 6 ampere-hours, fusible link fusing, thus can protect battery pack and relative electronic equipment effectively.
Claims (4)
