Description
本新型是有關於一種電阻元件，特別是指一種具有自動斷路功能的電阻元件。The present invention relates to a resistive element, and more particularly to a resistive element having an automatic breaking function.
參閱圖1，現有的電阻元件9包含一陶瓷棒91、一纏繞於該陶瓷棒91上的合金導線92、二套設於該陶瓷棒91相反二端的焊固帽93，及一包覆該陶瓷棒91、該合金導線92和部分焊固帽93的絕緣層94，該合金導線92的相反兩端分別焊接在該二焊固帽93，該二焊固帽93並焊黏於一電路(圖未示出)中，提供該電路所需的預設電阻。在一般的情況下，當電流通過該電阻元件9時，即因該合金導線92的阻值而作為電阻使用；當電流過大時，該合金導線92會因過熱而熔斷，而另外作為整個電路的保險絲使用。Referring to FIG. 1, the conventional resistive element 9 includes a ceramic rod 91, an alloy wire 92 wound on the ceramic rod 91, two soldering caps 93 disposed on opposite ends of the ceramic rod 91, and a cladding ceramic.

由於現有的電阻元件9的該合金導線92的熔點通常在900度至1500度之間，所以當電流呈小幅過流時，預計作為保險絲使用的該合金導線92並未依預期的熔斷，而是不斷的發熱，從而導致周遭的溫度過高而對其他電子元件造成損害，甚至引起安全問題。Since the melting point of the alloy wire 92 of the existing resistive element 9 is usually between 900 and 1500 degrees, when the current is slightly overcurrent, the alloy wire 92 used as a fuse is not expected to be blown as expected, but Constant heating, which causes the surrounding temperature to be too high, causing damage to other electronic components and even causing safety problems.
因此，現有的電阻元件9需要改善，以克服現有電阻元件9在小幅過流時的過熱問題。Therefore, the existing resistive element 9 needs to be improved to overcome the problem of overheating of the existing resistive element 9 during a small overcurrent.
因此，本新型之目的，即在提供一種電流小幅過流而發熱時會自動斷路的電阻元件。Therefore, the object of the present invention is to provide a resistance element that automatically breaks when a current is slightly overcurrent and generates heat.

本新型電阻元件在實際應用於電路中，當電流穩定通過時，由於該電阻單元3的合金線31的阻值遠大於該斷路保險單元4的溫度保險絲41，因此可以忽略不計該斷路保險單元4之溫度保險絲41的阻值，而以該電阻單元3的合金線31做為電阻使用；特別地，在電流小幅過流的情況下，由於該斷路保險單元4的溫度保險絲41的熔點遠低於該電阻單元3的合金線31，所以該溫度保險絲41會在該合金線31尚未達高溫時即先行熔斷，而令整個電路斷路，進而令本新型電阻元件不會因該電阻單元3的合金線31過熱而影響周遭其他的電子元件。The resistor element of the present invention is actually applied to a circuit. When the current is stably passed, since the resistance value of the alloy wire 31 of the resistor unit 3 is much larger than the temperature fuse 41 of the circuit breaker unit 4, the circuit breaker unit 4 can be ignored. The resistance of the temperature fuse 41 is used as the resistance of the alloy wire 31 of the resistor unit 3; in particular, in the case of a small overcurrent of the current, the melting point of the thermal fuse 41 of the open circuit fuse unit 4 is much lower than The alloy wire 31 of the resistor unit 3, so that the temperature fuse 41 will be blown first when the alloy wire 31 has not reached a high temperature, and the entire circuit is broken, so that the resistor element of the present invention is not affected by the alloy wire of the resistor unit 3. 31 overheating affects other electronic components around.
要補充說明的是，本新型電阻元件還可於該電阻區24塗佈樹脂，該溫度保險區25塗佈助熔劑，進而確保在電流小幅過流的情況下，有效隔離該合金線31的熱能向外傳遞，同時，確保該溫度保險絲41比該合金線31先熔斷。It should be additionally noted that the novel resistive element can also apply a resin to the resistive region 24, and the temperature fuse 25 applies a flux to ensure effective isolation of the thermal energy of the alloy wire 31 in the event of a small overcurrent of the current. It is transmitted outward, and at the same time, it is ensured that the temperature fuse 41 is blown earlier than the alloy wire 31.
本新型電阻元件還可以應用半自動量產製程，先於圓棒狀的該基體1上套設該中置件22；然後在該基體 1的兩端分別套設二焊點件21，並令該二導線23分別焊接於該二焊點件21上；之後，再以機器自動作業而於該基體1的電阻區24中纏繞該合金線31，並將該合金線31相反兩端分別焊固於該焊點件21a及該中置件22上；然後於該中置件22及該焊點件21b上設置溫度保險絲41；最後，在該電阻單元3上塗佈數道作為防火、散熱等用途的塗層(圖未示出)，以及在該斷路保險單元4上塗佈助熔樹脂後，即可套設上該封裝管5，並使用該封口膠6固著該封裝管5兩端與該二焊點件21底部，以簡單且自動化程度高的工業量產方式生產製作。The novel resistive element can also be applied to a semi-automatic mass production process, and the middle member 22 is placed on the base 1 of the round bar shape; then in the base body Two solder joints 21 are respectively sleeved on both ends of the first solder joints 21, and the two solder wires 21 are respectively soldered to the solder joints 21; after that, the alloy is wound in the resistance region 24 of the substrate 1 by automatic machine operation. a wire 31, and the opposite ends of the alloy wire 31 are respectively soldered to the solder joint member 21a and the center member 22; then a thermal fuse 41 is disposed on the center member 22 and the solder joint member 21b; A plurality of coatings (not shown) for use in fire prevention, heat dissipation, and the like are applied to the resistor unit 3, and after the fluxing resin is coated on the circuit breaker unit 4, the package tube 5 can be sleeved. And the sealant 6 is used to fix both ends of the package tube 5 and the bottom of the second solder joint member 21, and is produced and produced in a simple and highly automated industrial mass production manner.
綜上所述，本新型電阻元件以該電阻單元3提供電路預定的阻值，並配合該斷路保險單元4在小幅電流過流時，提前於該電阻單元3先行熔斷而形成斷路，避免該電阻單元3溫度過高而影響周遭其他電子元件的正常運作，確實改善現有的電阻元件9(見圖1)在小幅電流過流時，該合金導線92不斷昇溫而不熔斷，致使周遭元件因過熱受損的問題，成功解決安全疑慮，故確實能達成本新型之目的。In summary, the resistor element of the present invention provides a predetermined resistance value of the circuit by the resistor unit 3, and cooperates with the circuit breaker unit 4 to prematurely fuse the resistor unit 3 to form an open circuit in advance of a small current overcurrent, thereby avoiding the resistor. The temperature of unit 3 is too high to affect the normal operation of other electronic components around, and it is indeed improved that the existing resistance element 9 (see Fig. 1) is heated and not blown during a small current overcurrent, causing the surrounding components to be overheated. The problem of loss, the successful resolution of security concerns, can indeed achieve the purpose of this new type.
