Description
Technical field
The present invention relates to a kind of circuit protection device, especially by the multiple straties being arranged in inside chamber
Heat affecting is so as to reduce the hot unbalance circuit protection device between multiple straties each other.
Background technology
When electric power acts on electronic installation, substantial amounts of electric current can be flowed into moment, and the electric current is referred to as surge current
(Inrush Current).When the surge current is repeatedly passed to installs circuit board on the electronic device, surge electricity
The electronic component or semiconductor device that the incoming meeting of stream causes to be integrated on circuit substrate cause reduced lifetime because damaging, deteriorating
Or functional deterioration.For this reason, extra circuit protection device needs to be installed on the circuit board.
The circuit protection device that one of which is known is thermistor.The thermistor is a kind of resistor element, its
Resistance can sensitively change according to heat energy.In more detail, the resistance value of the thermistor can be according to the temperature of its own or ring
Border temperature and change.In various thermistors, the thermistor with negative temperature coefficient is referred to as NTC thermistor
(Negative temperature coefficient Thermistor, negative tempperature coefficient thermistor).NTC temperature-sensitives electricity
Hinder as the temperature or environment temperature of its own rise and the reduction of its resistance value.
Because the features described above of NTC thermistor, the NTC thermistor is treated as protection device to use, to suppress wave
Gush electric current.Resistance value with the NTC thermistor for being used increases, and the effect that the NTC thermistor suppresses surge current increases
By force.Although can reach the effect for suppressing surge current well with the NTC thermistor of high resistance, suppress surge current
There is electric power and heat energy continuous loss afterwards.Therefore, when attempting to suppress surge current with NTC thermistor, preferably to use
NTC thermistor with low-resistance value.
In order to reduce electric power and heat-energy losses after surge current is suppressed, preferably to use surface region big or thermal diffusivity
Good NTC thermistor.
The Korean Patent Publication that Publication No. 2012-9303 circuit protection device of improved heat radiation.The circuit is protected
Be inserted in dish-like heat-dissipation resistor in chamber and the chamber is filled with improved heat radiation with inserts by protection unit.
Additionally, heat is produced electronic component to configure in chamber by Japanese patent discloses for Publication No. 2007-103687
It is interior and fill the chamber with the electronic component of improved heat radiation with resin type cement.
Such circuit protection device can show good thermal diffusivity when being used alone.However, when multiple
Above-mentioned circuit protection device is installed when on circuit boards, and generation heat is unbalance between those circuit protection devices, therefore suffers from
Electric power and hot loss of energy.More specifically, when surge current is incoming is provided with the circuit board of multiple circuit protection devices,
Because those circuit protection devices have different resistance values or thermal characteristics, electric current is only concentrated and flows through wherein particular electrical circuit protection dress
Put or almost no electric current flows through the particular electrical circuit protection device.As a result, it may occur that the particular electrical circuit protection device cannot
Meet generation heat between the situation of desired circuit protection function, and these circuit protection devices unbalance so as to cause electric power or heat
Loss of energy.For example, 5 ohm of NTC thermistors of (Ω) resistance value are installed when surge current is incoming and are provided with 5.1
During the circuit board of the NTC thermistor of ohm (Ω) resistance value, 5 ohm of NTC thermistors of (Ω) resistance value are with its resistance
Value is reduced to 0.2 ohm (Ω) and temperature increases to 130 DEG C, but 5.1 ohm of NTC thermistors of (Ω) resistance value are with it
Resistance value is slightly decreased to 4 ohm (Ω) and temperature increases to about 45 DEG C.Therefore, even if having between these NTC thermistors micro-
Small resistance difference, but it is unbalance that significant heat can occur between these NTC thermistors, and this heat is unbalance can be over time
And strengthen.
With the increase of electronic product, the appearance of the display device with high-res, such as OLED or UHD etc., largely
Electric current flow through this electronic product, the circuit protection device of low-resistance value is needed to use for this.But use existing NTC heat
There is limitation in reduction resistance in the circuit protection device of quick resistance.More specifically, increase is needed in order to reduce resistance
The size of NTC thermistor, however as the increase of thermistor size, manufacturing cost also can significantly rise.Therefore, only lead to
Cross increase NTC thermistor has limitation to drop low-resistance mode.

The circuit protection device dress of completion is installed on circuit boards to suppress surge current.
In the present embodiment, first circuit protecting element 20 and the overall upper tabular of the second circuit protection element 30,
And be disposed adjacent and face each other.In particular, preferably as first circuit protecting element 20 and second electricity
Road protection element 30 uses NTC thermistor.It is adjacent and face each other setting first circuit protecting element 20 with this second electricity
The reason for road protection element 30 is that this can not only reduce the size of the circuit protection device, and by first circuit
Heat affecting between protection element 20 and the second circuit protection element 30 reduces first circuit protecting element 20 and is somebody's turn to do
It is hot unbalance between second circuit protection element 30.In other words, when as first circuit protecting element 20 and the second circuit
When protection element 30 is using the NTC thermistor, protected with the second circuit when electric current flows through first circuit protecting element 20
Element 30, then cause first circuit protecting element 20 to produce heat with the second circuit protection element 30.Now, heat can be from heating
The larger circuit protecting element of amount is transferred to the less circuit protecting element of caloric value such that it is able to eliminate heat mistake between the two
Weighing apparatus.
First circuit protecting element 20 can have identical or different resistance value with the second circuit protection element 30.Nothing
Which type of resistance value there is by first circuit protecting element 20 and the second circuit protection element 30, due to both of which each other
It is connected in parallel, the resistance value and the second circuit that both merging resistance values can be less than first circuit protecting element 20 protect unit
The resistance value of part 30.Therefore, the circuit protection device can have relatively low resistance value, and the relatively low resistance value is difficult to lead to
Cross single first circuit protecting element 20 or second circuit protection element 30 is realized.In general, with NTC temperature-sensitives electricity
The increase of the size of resistance, the resistance value reduction of the NTC thermistor, conversely, the increase of the size with the NTC thermistor,
The manufacturing cost of the NTC thermistor also nominal price.According to the present embodiment, the parallel connection between two NTC thermistors can not only drop
Low between the two hot unbalance, and realize low cost and with the circuit protection device of relatively low merging resistance value.
Also, with the increase of electronic product, the appearance of the display device with high-res, such as OLED or UHD etc.,
Substantial amounts of electric current flows through this electronic product, and the circuit protection device of low-resistance value is needed to use for this.However, the present invention can expire
Sufficient this demand.
Especially, when first circuit protecting element 20 has different resistance values from the second circuit protection element 30
When, from the relatively low circuit protection device of resistance value in the middle of first circuit protecting element 20 and the second circuit protection element 30
The heat of generation is transferred to resistance value another circuit protection device higher, therefore promotes resistance value another circuit protection dress higher
The resistance change put.For example, when to the NTC thermistor and 5.1 ohm (Ω) for being provided with 5 ohm of (Ω) resistance values
When the circuit board of the NTC thermistor of resistance value applies surge current, 5 ohm of resistance of the NTC thermistor of (Ω) resistance value
Value is reduced to 0.2 ohm (Ω) while temperature increases to 130 DEG C, and 5.1 ohm of resistance of the NTC thermistor of (Ω) resistance value
Value is slightly decreased to 4 ohm (Ω) while temperature increases to about 45 DEG C.Therefore, even if having between two NTC thermistors small
Difference, it is unbalance that heat temporarily occurs between two NTC thermistors, but heat unbalance can over time be reduced or disappeared
Remove.In more detail, the heat for being produced from the NTC thermistors of 5 ohm of (Ω) resistance values is transferred to 5.1 ohm of (Ω) resistance values
NTC thermistor, therefore significantly reduce 5.1 ohm of resistance values of (Ω).Therefore, 5.1 ohm of NTC of (Ω) resistance value are flowed through
The magnitude of current of thermistor can also increase, so that 5.1 ohm of NTC thermistors of (Ω) resistance value produce further amounts of heat, because
And it is hot unbalance between two NTC thermistors of elimination.As a result, 80~90 DEG C are maintained in thermal equilibrium state temperature.
