Definitions
- the object of the invention is to provide a fuse solving the above-mentioned problem in a manner satisfactory in all respects. Consequently, the fuse should be cheap to manufacture and have an insignificant space requirement. It will appear from the following description how this object can be realized according to the invention but, in few words, the subject of the invention can be defined as a fuse lacking a separate, stationary holder. This means that it can form a portion of a current conductor which portion is integrated with the conductor from an electrical and a mechanical point of view.
- the current conductor does typically extend between on the one hand a current source, a storage battery or a generator, and on the other an electric load which typically but not exclusively is constituted by a electric motor installed in a vehicle.
- Fig. 1 illustrates the principle of a fuse member according to the invention.
- Fig. 2 shows a complete fuse for connection between a cable and a threaded bolt.
- Fig. 3 corresponds to Fig. 2 but shows a fuse unit arranged for connection between a cable and the pole bolt of a battery.
- Fig. 4 illustrates a second shape of the fuse member shown in Fig. 1.
- Fig. 5 corresponds to Fig. 4 but illustrates a third fuse member shape .
- the fuse member shown in Fig. 1 has two end portions 1 and 2 and an intermediate, narrow bridge portion 3 which will melt when the fuse is activated.
- the bridge portion consists of a metal having a relatively low melting point and, at the end portions of the unit, the bridge ends have coatings 4, 5 consisting of a material of high electrical conductivity, preferably copper, and intended to reduce the transition resistance between the fuse and the components to which it is connected. To facilitate such connection the end portions have through holes 6, 7.
- Fig. 2 shows a complete fuse unit the melt bridge of which can be shaped as shown in e.g. Fig. 1, Fig. 4 or Fig. 5. If one would use just the melt bridge and connect it between e.g. a bolt through hole 6 and the end of a flexible cable connected to end portion 5, melting of bridge 3 would cause end portions 1 and 2 to separate and, due to the flexibility of the cable, its separated end could fall down and, when connected to a voltage source, get into contact with earth or with some other component. This risk is eliminated in a complete fuse as shown in Fig. 2 since the bridge is there surrounded by a supporting jacket 8 of an insulating material, preferably a plastic.
- the jacket is secured to both end portions, in this case by inbossments 9 engaging corresponding depressions in the end portions. It should however be underlined that the necessary form-stable connection between the jacket and each of the two end portions can be achieved in many other ways, such as by the use of guide pins.
- jacket 8 For the purpose of making it possible conveniently to determine whether the fuse has been activated or not jacket 8 is provided with a central window 10 permitting direct observation of bridge 3.
- Fig. 3 The only difference between Fig. 3 and Fig. 1 or 2 is that in Fig. 3 one of the end portions is shaped like a cable shoe 11 for connection to the pole bolt of a accumulator battery.
- the fuse member illustrated in Fig. 4 does, on each side of melt bridge 3, exhibit through holes 12 for guide pins securing the jacket. Also according to the embodiment of Fig. 5 there are such holes 12 and, additionally, a central hole 13 in bridge 3.
- the effective current-conducting cross- sectional area of the bridge will depend on the diameter of hole 13.
- the diameter of hole 13 it is possible, using one and the same fuse member of a predetermined, standardized size, to vary the rated current intensity of the fuse within a relatively wide interval, for example 50-400 A.
- This possibility is an advantage further reducing the manufacturing and marketing costs of fuses according to the invention.
- it is suitable to provide the jacket 8 with information concerning the actual rated current of the fuse. Such information can be presented in many different ways, for example by variation of the colour of jacket 8 or by providing it with figures or symbols.
- the fuse when the fuse is mounted inside a closed space adjacent to a accumulator battery, it can be gas sealed so that the spark formation occurring upon melting is prevented from igniting gas assembled inside the confined space. If in such cases one wishes to preserve the possibility of determining by direct observation whether bridge 3 has melted or not one does not use an open window 10 as shown in Figs. 2 and 3 but does instead use a jacket 8 consisting of a transparent material.
