However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to an electronic component. The core of the embodiment is that the circuit board comprises a circuit board 1, a first metal plate 2, a second metal plate 3, a first short circuit pin 4 and a second short circuit pin 5; the first short-circuit pin 4 is used for short-circuiting the circuit board 1, the first metal plate 2 and the second metal plate 3; the second shorting pin 5 shorts any two of the circuit board 1, the first metal plate 2, and the second metal plate 3. Through additionally arranging the second short circuit pin 5, the second short circuit pin is enabled to be in short circuit with any two of the circuit board 1, the first metal plate 2 and the second metal plate 3, and overlarge current on the circuit board 1, the first metal plate 2 and the second metal plate 3 is led to the first metal plate 2 or the second metal plate 3 which is grounded, so that local current on the circuit board 1, the first metal plate 2 or the second metal plate 3 is reduced. The following detailed description of the present embodiments is provided for ease of understanding and is not intended to limit the scope of the present embodiments.
The first metal plate 2 and the second metal plate 3 are both grounded.
As shown in fig. 1, the second metal plate 3 is sandwiched between the circuit board 1 and the first metal plate 2. It should be noted that, for convenience of understanding and description, the second metal plate 3 is sandwiched between the circuit board 1 and the first metal plate 2 in this embodiment as an example, and the positional relationship between the circuit board 1, the first metal plate 2, and the second metal plate 3 is not specifically limited in this embodiment. The first shorting pin 4 is in contact with the circuit board 1, the first metal plate 2, and the second metal plate 3, respectively, and short-circuits the circuit board 1, the first metal plate 2, and the second metal plate 3. When the local current on the circuit board 1 is too large, the second short-circuit pin 5 is used for short-circuiting the circuit board 1 and the first metal plate 2, and the too large local current on the circuit board 1 is drained to the first metal plate 2 so as to reduce the too large local current on the circuit board 1. The second shorting pin 5 is in contact with only the circuit board 1 and the first metal plate 2 to prevent local current from being conducted to the second metal plate 3.
As shown in fig. 2, when the local current on the circuit board 1 is too large, the second shorting pin 5 can also be used to short the circuit board 1 and the second metal plate 3 to drain the too large local current on the circuit board 1 to the second metal plate 3, so as to reduce the too large local current on the circuit board. The second shorting pin 5 is only in contact with the circuit board 1 and the second metal plate 3 to prevent local current from being conducted to the first metal plate 2.
As shown in fig. 3, when the local current of one of the first metal plate 2 and the second metal plate 3 is too large, the second shorting pin 5 is used to short-circuit the first metal plate 2 and the second metal plate 3, so as to conduct the too large local current to the other metal plate, thereby reducing the local current. The second shorting pin 5 is only in contact with the first and second metal plates 2, 3 to prevent local current from being conducted to the circuit board 1.
Preferably, the second shorting pin 5 is provided at a position 1 to 10mm from the first shorting pin 4. Through repeated experiments, the second short-circuit pin is arranged at a position 1-10 mm away from the first short-circuit pin 4, and the effect of reducing the local current is better.
Preferably, the second shorting pin 5 has a lower electrical resistance than the first shorting pin 4. The smaller the resistance of the second shorting pin 5, the better the effect of draining local excess current. The effect of reducing the local current is improved by using the second shorting pin 5 having a lower resistance.
A second embodiment of the present invention relates to an electronic component. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the third embodiment of the present invention, the second shorting pin 5 is provided in plurality.

As shown in fig. 4, when the local current on the circuit board 1 is too large, two second shorting pins 5 arranged side by side are used to short-circuit the circuit board 1 and the first metal plate 2, so as to conduct the too large local current on the circuit board 1 to the first metal plate 2, thereby reducing the too large local current on the circuit board 1. The second shorting pin 5 is in contact with only the circuit board 1 and the first metal plate 2 to prevent local current from being conducted to the second metal plate 3.
As shown in fig. 5, when the local current on the circuit board 1 is too large, the circuit board 1 and the second metal plate 3 may be shorted by using two second shorting pins 5, so that the too large local current on the circuit board 1 is drained to the second metal plate 3, so as to reduce the too large local current on the circuit board. The second shorting pin 5 is only in contact with the circuit board 1 and the second metal plate 3 to prevent local current from being conducted to the first metal plate 2.
As shown in fig. 6, when the local current of one of the first metal plate 2 and the second metal plate 3 is too large, the first metal plate 2 and the second metal plate 3 are shorted by using two second shorting pins 4, and the too large local current is drained to the other metal plate to reduce the local current. The second shorting pin 5 is only in contact with the first and second metal plates 2, 3 to prevent local current from being conducted to the circuit board 1.
In this embodiment, the effect of reducing the local current is improved by additionally providing a plurality of second shorting pins 5.
It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
