Description
本發明係關於一種電路保護裝置，特別是一種將複數個電阻加熱元件以一彼此熱影響的方法安排於一箱盒中的電路保護裝置，據此，可消弭於該等電阻加熱元件間的熱失衡。 The present invention relates to a circuit protection device, and more particularly to a circuit protection device for arranging a plurality of resistance heating elements in a box in a thermal influence on each other, whereby the heat between the resistance heating elements can be eliminated Unbalanced.
當電力施加於一電子裝置時，大量的電流會瞬間流入，該電流被稱為「湧浪電流(Inrush Current)」。當該湧浪電流重複地傳入到裝設於該電子裝置上的電路板時，該湧浪電流的傳入會導致電子組件或半導體裝置的損壞，使使用壽命減短和功能退化。為了此原因，該電路板可裝設一額外的電路保護裝置。 When electric power is applied to an electronic device, a large amount of current flows instantaneously, and this current is called "Inrush Current". When the surge current is repeatedly transmitted to the circuit board mounted on the electronic device, the incoming of the surge current may cause damage to the electronic component or the semiconductor device, resulting in shortened service life and functional degradation. For this reason, the board can be equipped with an additional circuit protection device.
其中一種被熟知的電路保護裝置為熱敏電阻，熱敏電阻是一種電阻器元件，其電阻會依照熱能敏感地改變。更詳細的說，該熱敏電阻的電阻值會依照其自身的溫度或周遭的溫度而改變。於各種熱敏電阻中，具有一負溫度係數的一熱敏電阻被稱為一負溫度係數熱敏電阻(NTC Thermistor,Negative temperature coefficient Thermistor)。 One well-known circuit protection device is a thermistor, which is a resistor element whose resistance changes sensitively according to thermal energy. In more detail, the resistance value of the thermistor changes according to its own temperature or ambient temperature. Among various thermistors, a thermistor having a negative temperature coefficient is called a NTC Thermistor (Negative temperature coefficient Thermistor).
因為上述特徵，該NTC熱敏電阻被當成一保護裝置來使用，以抑制湧浪電流。隨著該NTC熱敏電阻的電阻值增加，該NTC熱敏電阻抑制湧浪電流的功效可被增強。雖然運用高電阻值的NTC熱敏電阻可達到抑制湧浪電流的重大功效，但抑制湧浪電流後可能發生電力與熱能持續損失。因此，當試 圖以NTC熱敏電阻抑制湧浪電流時，可能會使用具有一低電阻值的NTC熱敏電阻。 Because of the above characteristics, the NTC thermistor is used as a protection device to suppress surge current. As the resistance value of the NTC thermistor increases, the effect of the NTC thermistor to suppress surge current can be enhanced. Although the use of high-resistance NTC thermistors can achieve significant effects in suppressing surge currents, continuous loss of power and thermal energy may occur after suppression of surge currents. Therefore, when you try When the NTC thermistor is used to suppress the surge current, an NTC thermistor with a low resistance value may be used.
為了要減少電力與熱能於抑制湧浪電流後的損失，可使用表面區域大或散熱性良好的一NTC熱敏電阻。 In order to reduce the loss of electric power and thermal energy after suppressing the surge current, an NTC thermistor having a large surface area or good heat dissipation can be used.
韓國未經實體審查的專利公開號10-2012-0009303揭露了一種具有改良的散熱性的電路保護裝置。該電路保護裝置透過定位一碟型加熱電阻器於一箱盒並用填充料填充該箱盒中以改良散熱性。 A circuit protection device having improved heat dissipation is disclosed in Korean Unexamined Patent Publication No. 10-2012-0009303. The circuit protection device improves the heat dissipation by positioning a dish-type heating resistor in a box and filling the box with a filler.
此外，日本未經實體審查的專利公開號2007-103687揭露了一種電子組件，該電子組件透過置放一熱產生電子元件於一箱盒中並用樹脂水泥填充該箱盒以改良散熱性。 Further, Japanese Unexamined Patent Publication No. 2007-103687 discloses an electronic component which is placed in a case by placing a heat generating electronic component and filling the case with resin cement to improve heat dissipation.
諸如此類的一電路保護裝置可於單獨被使用時展現出良好的加熱性。然而，當複數個上述的電路保護裝置裝設於電路板上時，該等電路保護裝置之間發生熱失衡，因此仍遭受電力與熱能的損失。更具體地說，當湧浪電流傳入裝設有該等電路保護裝置的電路板時，因為該等電路保護元件具有不同的電阻值或熱特性，電流僅集中流經其中一特定電路保護裝置或幾乎沒有電流流經該特定電路保護裝置。結果，該特定電路保護裝置可能無法實現想要的電路保護功能之狀況可能發生，且該等電路保護裝置之間可能發生熱失衡，因此導致電力或熱能的損失。舉例來說，當湧浪電流傳入裝設有具有5歐姆(Ω)電阻值的一NTC熱敏電阻與具有5.1歐姆(Ω)電阻值的一NTC熱敏電阻的一電路板時，具有5歐姆(Ω)初始電阻值的NTC熱敏電阻的電阻值呈現隨著溫度增加至130℃而降低至0.2歐姆(Ω)，反之，具有5.1歐姆(Ω)初始電阻值的NTC熱敏電阻的電阻值呈現隨著溫度增加至約45℃而降低至4歐姆(Ω)。因此，即使該等 NTC熱敏電阻間具有微小的電阻差異，顯著的熱失衡就會在該等NTC熱敏電阻間發生，且熱失衡會隨著時間而增強。 A circuit protection device such as this can exhibit good heating when used alone. However, when a plurality of the above-mentioned circuit protection devices are mounted on a circuit board, thermal imbalance occurs between the circuit protection devices, and thus the power and thermal energy are still lost. More specifically, when the surge current is transmitted to the circuit board on which the circuit protection devices are mounted, since the circuit protection components have different resistance values or thermal characteristics, the current flows only through one of the specific circuit protection devices. Or almost no current flows through the particular circuit protection device. As a result, conditions in which the particular circuit protection device may not achieve the desired circuit protection function may occur, and thermal imbalances may occur between the circuit protection devices, thereby causing loss of power or thermal energy. For example, when the surge current is transmitted to a circuit board having an NTC thermistor having a resistance value of 5 ohms (Ω) and an NTC thermistor having a resistance value of 5.1 ohms (Ω), The resistance value of the NTC thermistor with ohmic (Ω) initial resistance value decreases to 0.2 ohms (Ω) as the temperature increases to 130 ° C. Conversely, the resistance of the NTC thermistor with 5.1 ohm (Ω) initial resistance value The value appears to decrease to 4 ohms (Ω) as the temperature increases to approximately 45 °C. So even if so There is a small difference in resistance between NTC thermistors, a significant thermal imbalance occurs between the NTC thermistors, and the thermal imbalance increases over time.
隨著電子產品的增大，與高解析度的顯示裝置(如OLED或UHD等等)的出現，大量的電流流通於此類電子產品，使得具有一低電阻值的電路保護裝置的使用被需要。習知由NTC熱敏電阻組成的電路保護裝置具有一降低電阻的限制。更具體地說，雖然NTC熱敏電阻必須具有一增大尺寸以降低其電阻，但製造成本將依該NTC熱敏電阻的尺寸之增加比例而指數地增加。因此，僅藉由增大該NTC熱敏電阻以降低電阻具有限制。 With the increase of electronic products, with the emergence of high-resolution display devices (such as OLED or UHD, etc.), a large amount of current flows through such electronic products, so that the use of circuit protection devices having a low resistance value is required. . It is known that circuit protection devices consisting of NTC thermistors have a limitation in reducing resistance. More specifically, although the NTC thermistor must have an increased size to reduce its resistance, the manufacturing cost will increase exponentially in proportion to the increase in the size of the NTC thermistor. Therefore, there is a limit only by increasing the NTC thermistor to lower the resistance.

The filler 80 not only supports the first circuit protection component 20 and the second circuit protection component 30 in the receiving space 15, but also ensures the heat from the first circuit protection component 20 and the second circuit protection component 30. The divergence of efficiency. Therefore, the filler 80 preferably uses a material having excellent heat dissipation properties.
圖4與圖5例示了一種製造根據本發明第一實施例的電路保護裝置的過程。首先，準備該箱盒10、該第一電路保護元件20以及該第二電路保護元件30。該第一電路保護元件20與該第二電路保護元件30藉由該輸入連接器40與該輸出連接器50而相互連接。該輸入連接器40與該輸出連接器50分 別連接該第一引線60與該第二引線70。 4 and 5 illustrate a process of fabricating a circuit protection device in accordance with a first embodiment of the present invention. First, the case 10, the first circuit protection component 20, and the second circuit protection component 30 are prepared. The first circuit protection component 20 and the second circuit protection component 30 are connected to each other by the input connector 40 and the output connector 50. The input connector 40 and the output connector 50 The first lead 60 and the second lead 70 are not connected.
如圖4所示，於此狀態下，該第一電路保護元件20與該第二電路保護元件30容置於該箱盒10的接收空間15。該第一引線60的末端以及該第二引線70的末端透過該等導引孔16延伸至該箱盒外。 As shown in FIG. 4, in this state, the first circuit protection component 20 and the second circuit protection component 30 are housed in the receiving space 15 of the box 10. The end of the first lead 60 and the end of the second lead 70 extend through the guide holes 16 to the outside of the case.
接下來，該箱盒10的接收空間15填充該填充物80，因此完成該電路保護裝置。結果完成的電路保護裝置裝設於一電路板上以抑制湧浪電流。 Next, the receiving space 15 of the case 10 fills the filling 80, thus completing the circuit protection device. The resulting circuit protection device is mounted on a circuit board to suppress surge current.
於本實施例中，該第一電路保護元件20與該第二電路保護元件30各自為一平盤狀，且被安排彼此相鄰且相互面對。更具體的說，一NTC熱敏電阻較佳地被使用以當成該第一電路保護元件20以及該第二電路保護元件30。該第一電路保護元件20與該第二電路保護元件30被安排彼此相鄰且相互面對的原因是因為此配置可以減少該電路保護裝置的尺寸，以及由於該第一電路保護元件20與該第二電路保護元件30彼此影響的狀況之優點而減少該第一電路保護元件20與該第二電路保護元件30間的熱失衡。換句話說，當該NTC熱敏電阻被使用以當成該第一電路保護元件20與該第二電路保護元件30時，電流流經該第一電路保護元件20與該第二電路保護元件30，導致該第一電路保護元件20與該第二電路保護元件30產生熱。此時，熱會從產生較大量的熱的一電路保護元件轉移到產生較小量的熱的另一電路保護元件，因此消弭兩者間的熱失衡。 In this embodiment, the first circuit protection component 20 and the second circuit protection component 30 are each in a flat disk shape, and are arranged adjacent to each other and face each other. More specifically, an NTC thermistor is preferably used as the first circuit protection component 20 and the second circuit protection component 30. The reason why the first circuit protection component 20 and the second circuit protection component 30 are arranged adjacent to each other and face each other is because the configuration can reduce the size of the circuit protection device, and because the first circuit protection component 20 The advantage of the condition in which the second circuit protection component 30 affects each other reduces the thermal imbalance between the first circuit protection component 20 and the second circuit protection component 30. In other words, when the NTC thermistor is used as the first circuit protection component 20 and the second circuit protection component 30, current flows through the first circuit protection component 20 and the second circuit protection component 30, The first circuit protection component 20 and the second circuit protection component 30 are caused to generate heat. At this point, heat is transferred from a circuit protection component that produces a greater amount of heat to another circuit protection component that produces a smaller amount of heat, thereby eliminating thermal imbalance between the two.
該第一電路保護元件20與該第二電路保護元件30可具有相同或不同的電阻值。由於無論該第一電路保護元件20與該第二電路保護元件30之電阻值，兩者皆彼此並聯連接，所以兩者之合併電阻值會低於該第一電路保護元件20的電阻值或該第二電路保護元件30的電阻值。因此，可了解該電路 保護裝置具有一相對低的電阻值，該相對低的電阻值很難由單獨的第一電路保護元件20或第二電路保護元件30所得到。一般來說，該NTC熱敏電阻的一電阻值的降低與該NTC熱敏電阻的尺寸的增加是反比例，反之，該NTC熱敏電阻的製造成本的增加與該NTC熱敏電阻的尺寸的增加卻是一指數比率。根據本實施例，兩個NTC熱敏電阻間的並聯降低了兩者間的熱失衡，且了解該電路保護裝置以低成本而具有一相對低的合併電阻值。本文中，因為電子產品的增大，高解析度的顯示裝置(如OLEDs和UHDs等等)的出現，大量的電流流通於該電子產品，因此需要具有一低電阻值的一電路保護裝置。本發明可滿足此需求。 The first circuit protection component 20 and the second circuit protection component 30 can have the same or different resistance values. Since the resistance values of the first circuit protection component 20 and the second circuit protection component 30 are connected in parallel with each other, the combined resistance value of the two is lower than the resistance value of the first circuit protection component 20 or The resistance value of the second circuit protection component 30. Therefore, the circuit can be understood The protection device has a relatively low resistance value that is difficult to obtain from the separate first circuit protection component 20 or second circuit protection component 30. In general, the decrease in the resistance of the NTC thermistor is inversely proportional to the increase in the size of the NTC thermistor. Conversely, the increase in the manufacturing cost of the NTC thermistor and the increase in the size of the NTC thermistor It is an index ratio. According to this embodiment, the parallel connection between the two NTC thermistors reduces the thermal imbalance between the two, and it is understood that the circuit protection device has a relatively low combined resistance value at low cost. In this paper, because of the increase in electronic products, the emergence of high-resolution display devices (such as OLEDs and UHDs, etc.), a large amount of current flows through the electronic product, and thus a circuit protection device having a low resistance value is required. The present invention satisfies this need.
特別地，當該第一電路保護元件20與該第二電路保護元件30具有不同的電阻值時，熱產生於該第一電路保護元件20與該第二電路保護元件30當中具有一較低電阻值的一電路保護裝置，並將熱轉移到具有一較高電阻值的另一電路保護裝置，因此造成具有該較高電阻值的另一電路保護裝置的電阻值改變。 In particular, when the first circuit protection component 20 and the second circuit protection component 30 have different resistance values, heat is generated in the first circuit protection component 20 and the second circuit protection component 30 has a lower resistance. A circuit protection device of value transfers heat to another circuit protection device having a higher resistance value, thereby causing a change in resistance value of another circuit protection device having the higher resistance value.
舉例來說，當湧浪電流施加於裝設有具有5歐姆(Ω)的電阻值的一NTC熱敏電阻以及具有5.1歐姆(Ω)的電阻值的一NTC熱敏電阻的一電路板時，具有5歐姆(Ω)的電阻值的NTC熱敏電阻的電阻值呈現隨著溫度增加至130℃而降低至0.2歐姆(Ω)，反之，具有5.1歐姆(Ω)初始電阻值的NTC熱敏電阻的電阻值呈現隨著溫度增加至約45℃而降低至4歐姆(Ω)。因此，即使該等NTC熱敏電阻間具有微小的差異，熱失衡在該等NTC熱敏電阻間發生，但熱失衡會隨著時間而減少或消弭。更詳細的說，自具有5歐姆(Ω)的電阻值的NTC熱敏電阻產生的熱轉移到具有5.1歐姆(Ω)的電阻值的NTC熱敏電阻，因此相當地降低了具有5.1歐姆(Ω)的初始電阻值的NTC熱敏電阻的一電阻值。因此，流經具 有5.1歐姆(Ω)的初始電阻值的NTC熱敏電阻的一電流量增加，使得具有5.1歐姆(Ω)的初始電阻值的NTC熱敏電阻產生一更大量的熱，因此消弭該等NTC熱敏電阻間的熱失衡。結果，一熱平衡狀態被維持在一溫度為80~90℃。 For example, when a surge current is applied to a circuit board equipped with an NTC thermistor having a resistance value of 5 ohms (Ω) and an NTC thermistor having a resistance value of 5.1 ohms (Ω), The resistance value of an NTC thermistor with a resistance value of 5 ohms (Ω) appears to decrease to 0.2 ohms (Ω) as the temperature increases to 130 ° C. Conversely, an NTC thermistor with an initial resistance value of 5.1 ohms (Ω) The resistance value appears to decrease to 4 ohms (Ω) as the temperature increases to about 45 °C. Therefore, even if there is a slight difference between the NTC thermistors, thermal imbalance occurs between the NTC thermistors, but the thermal imbalance will decrease or eliminate over time. In more detail, the heat generated from an NTC thermistor having a resistance value of 5 ohms (Ω) is transferred to an NTC thermistor having a resistance value of 5.1 ohms (Ω), and thus is considerably reduced by 5.1 ohms (Ω). The initial resistance value of a resistance value of the NTC thermistor. Therefore, flow through An amount of current of the NTC thermistor having an initial resistance value of 5.1 ohms (Ω) is increased, so that the NTC thermistor having an initial resistance value of 5.1 ohms (Ω) generates a larger amount of heat, thereby eliminating the NTC heat. Thermal imbalance between the varistor. As a result, a thermal equilibrium state is maintained at a temperature of 80 to 90 °C.
