Embodiment
Below, with reference to Fig. 1～Fig. 4, embodiments of the present invention are described.Among each figure, to identical or similar parts or key element, be marked with the same tag.
Fig. 1 is the figure of general structure of the 1st embodiment of explanation fusing resistor of the present invention.In this example, the structure of resistive element 1 is, as the insulating properties matrix, cap 2a, the 2b of conductive metal is installed at two ends with columnar pottery, glass, and the resistive conductor of NiCr etc. is wound into helical form, and the two ends of resistive conductor are welded on cap 2a, the 2b.The fusing point of used metal is the value higher than the fusing point of low-melting-point metal 6 in this welding.Conducting wire 3a on cap 2a, but also can use lid with wire.Use does not just need wire in cap 2b side during with the lid of wire, so, also can cut away wire.Implemented the insulation coating on the surface of resistive element 1, but the coating of might not insulating.
In the present embodiment, be to adopt wire resistor as resistive element, still, resistive element of the present invention is not limited to wire resistor, the resistor that also can adopt the overlay film resistor, cement resistor etc. of oxidized metal etc. to be fit to.When adopting the overlay film resistor, after the insulating properties matrix has formed overlay film resistance, cover both ends with cap, like this, cap is connected with resistive element.
On insulating properties substrate 5, the predetermined spacing of being separated by between the through hole that the through hole that inserts for side's arm 4a of helical spring 4 and the Square wire 3a for resistive element 1 insert, and, in the above (installed surface one side of helical spring 4) is provided with the recess 5b that can loosely insert for the spire 4c of helical spring 4.Why will loosely insert the spire 4c of helical spring 4, be for fear of causing spring compression owing to spire 4c inserts recess 5b, avoiding affecting the cause of spring constant.Therefore, if when the impact of spring constant do not become problem, can loosely not insert yet.Which kind of situation no matter, the through hole that recess inserts usefulness with respect to arm 4a are formed on relatively position on one side, like this, can limit the direction of helical spring 4.When the arm 4a of helical spring 4 is inserted through hole, also can be fixed on arm 4a on the insulating properties substrate 5 with bonding agent (for example silicon is bonding agent).
Low-melting-point metal 6 is located between the arm 4b of cap 2b and helical spring 4, is the metal of fusing just when reaching uniform temperature, and the fuse metal is wherein a kind of.Also can adopt the solder of predetermined fusing point.
Housing 7 is entrenched in the periphery of insulating properties substrate 5, and insulating properties substrate 5 is covered, and takes in and is protecting inner resistive element 1 and helical spring 4.If adopt transparent material (such as allyl resin etc.), can have an X-rayed inside, easily be confirmed whether action.Certainly, housing 7 is not indispensable.
The following describes the assembling of this fusing resistor.The above-mentioned through hole of a Square wire 3a of resistive element 1 insertion insulating properties substrate 5, lid 2a is inserted into recess 5a, with bonding agent resistive element 1 is fixed on the insulating properties substrate 5.When fixed resistive element 1, the welding portion of the resistive conductor on the cap 2b on top is fixed toward the outer side.This is for welding portion is not disturbed and being connected of the low-melting-point metal of the arm 4b of helical spring 4.For helical spring 4, arm 4a is passed through hole, spire 4c is inserted recess 5b.When arm 4a passes, also can use like that as mentioned above bonding agent.At this state, arm 4b leaves cap 2b fully.At this state, the contact portions of the side of cap 2b as a side, as the opposing party's contact portions, the elastic force of opposing helical spring 4 makes above-mentioned two contact portions contact, and welds with low-melting-point metal 6 the bent front ends of the arm 4b of helical spring 4.Then, cover upper shell 7, thus fusing resistor is assembled.In addition, in this embodiment, make the front end of arm 4b be approximately perpendicular to the bending of cap 2b ground, still, it is crooked that the shape of leading section might not be wanted, and also can be suitable shape.
Fig. 2 is the figure of the modified example of explanation the 1st embodiment shown in Figure 1, is the figure corresponding with Fig. 1 (C).In this embodiment, the number of turns of spire 4c is 3 circles.Therefore, compare with embodiment illustrated in fig. 1, the width of spire 4c increases, and the recess 5b that inserts for spire 4c also correspondingly increases.
In addition, the degree of depth of recess 4c is subject to the restriction of insulating properties substrate 5 thickness, still, as long as it is just enough to have the degree of depth that can limit installation direction, there is no need spire 4c is imbedded very dark, as long as the part of spire 4c is inserted.
Fig. 3 represents the action of fusing resistor shown in Figure 1, and Fig. 3 (A) represents normal condition, the off-state that Fig. 3 (B) expression abnormal current causes.
In normal condition, shown in Fig. 3 (A), arm 4b is keeping the state that is connected with cap 2b, forms closed circuit between wire 3a and the arm 4a.When overcurrent flow through, the heat that resistive element 1 produces was with cap 2b heating, low-melting-point metal 6 meltings.Simultaneously, by the spring force that helical spring 4 is accumulated, arm 4b leaves cap 2b hastily, shown in Fig. 3 (B), becomes open circuit between wire 3a and the arm 4a, and the circuit that is inserted with fusing resistor is disconnected.
In addition, even without overcurrent, when the environment temperature abnormal ascending, low-melting-point metal 6 by this heat fusing the time, similarly, become open circuit between wire 3a and the arm 4a, the circuit that is inserted with fusing resistor is disconnected.
Fig. 4 is the front view of general structure of the 2nd embodiment of explanation fusing resistor of the present invention.In this embodiment, wire 3b also is installed on cap 2b.Wire 3b is used as side's contact portions.Be connected with low-melting-point metal 6 with the arm 4b as the opposing party's contact portions, this point is identical with the 1st embodiment.The action of this fusing resistor is, the heat of cap is transmitted to wire 3b, low-melting-point metal fusing, and illustrated in fig. 3 identical, detailed description is omitted for it.
The present invention is applicable to fusing resistor.In this fusing resistor; as with respect to the protection component of the overcurrent in the circuit and electrical fuse element, the especially resistive element and the Thermal Cutoffs that use; be connected in series in circuit, the heat of the resistive element that abnormal current causes is the Thermal Cutoffs element fusing that is made of low-melting-point metal.
