Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example one

Referring to fig. 1-2, an anti-short circuit battery, a housing 1, an inner core 2, the housing 1 is sleeved outside the inner core 2, both ends of the housing 1 are respectively provided with a positive terminal 31 and a negative terminal 32, the positive terminal of the inner core 2 is directly electrically connected with the positive terminal 31, the negative terminal of the inner core 2 is electrically connected with an inductance coil 4, one end of the inductance coil 4 far away from the inner core 2 is electrically connected with a current conducting plate 5, the current conducting plate 5 is fixedly connected with a connecting block 7 made of an insulating material, the connecting block 7 is fixedly connected on the negative terminal 32, the current conducting plate 5 is connected with a T-shaped plate 6 made of iron in a damping sliding manner, the T-shaped plate 6 is abutted against the negative terminal.

The trigger mechanism comprises a capacitor 9 and an electromagnetic coil 8, the capacitor 9 comprises two pole plates, one pole plate is electrically connected with the inductance coil 4, the other pole plate is electrically connected with the electromagnetic coil 8, and one end, far away from the pole plate, of the electromagnetic coil 8 is electrically connected to the inductance coil 4.

In this embodiment, the T-shaped plate 6 and the negative end 32 are in a state of abutting against each other, and at this time, the negative electrode of the inner core 2 is electrically connected to the negative end 32 through the inductance coil 4, the conductive plate 5 and the T-shaped plate 6, and since the inductance coil 4 has the electrical characteristics of direct current connection and alternating current disconnection, when power is normally supplied to the outside, the inductance coil 4 does not generate obvious inductive reactance, and it is ensured that the battery can normally supply power to the outside;

when the battery normally supplies power to the outside, because the resistance of the inductance coil 4 is extremely small, the voltage at two ends of the inductance coil is extremely small, and because the trigger mechanism is connected on the inductance coil 4 in parallel, the voltage between two pole plates of the capacitor 9 is extremely small, the capacitor 9 cannot be broken down, so that the electromagnetic coil 8 is always in a power-off state, and an obvious magnetic field cannot be generated to attract the T-shaped plate 6 to move.

When the external short circuit occurs to cause the short circuit of the positive terminal 31 and the negative terminal 32 of the battery, the resistance loaded by the inner core 2 is extremely small at the moment and extremely large current can be generated instantaneously, at the moment, according to the characteristics of the inductance coil 4, the extremely large induction resistance, namely inductive reactance, can be generated instantaneously on the inductance coil 4, and then the two ends of the inductance coil 4 generate instantaneous high voltage, because the trigger mechanism is connected in parallel with the two ends of the inductance coil 4, the two ends of the capacitor 9 can present the same voltage as the inductance coil 4, the voltage drop at the two ends of the capacitor 9 is far larger than the load range of the capacitor 9 and is broken down, namely, the two electrodes of the capacitor 9 are electrically connected to enable the electromagnetic coil 8 to be electrified in a short time, and then the electromagnetic coil 8 is electrified to generate obvious magnetism and attract the T-shaped plate 6 to be disconnected with the negative.

Example two

Referring to fig. 3-4, the present embodiment differs from the first embodiment in that: casing 1 and negative pole end 32 have seted up a line hole 10 jointly, and the one end of line hole 10 communicates with the external world, and the other end in line hole 10 is relative with T template 6, and it has nylon wire 11 to run through in line hole 10, and the one end of nylon wire 11 and T template 6 fixed connection, and the other end of nylon wire 11 is connected with a plastics material's control piece 12.

In this embodiment, after the T-shaped plate 6 is disconnected from the negative end 32 due to a short circuit of the battery, the T-shaped plate 6 is driven by pulling the control plate 12 outwards to abut against the negative end 32 again, so that the battery can supply power to the outside again.

Although the terms of the housing 1, the core 2, the positive terminal 31, the negative terminal 32, the inductor coil 4, the conductive plate 5, the T-shaped plate 6, the connection block 7, the electromagnetic coil 8, the capacitor 9, the wire hole 10, the nylon wire 11, the control piece 12, etc. are used more frequently herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
