Definitions
- the invention relates to a method for the production of an electrical fuse fixing a surface of a ceramic part on a fuse fuse, and a fuse with a ceramic first part and a second part, the an electrically conductive wire, namely the fuse element of the Fuse is.
- ceramic material in the sense of the invention all ceramics as well as metal and glass ceramics and also glasses to understand.
- Fastenings of this type play a part in the manufacture electrical fuses using the so-called Thick film technology plays a major role.
- Thick film technology With thick film technology are complete circuits on a ceramic Substrate created. This is done on a ceramic substrate electrical contacts, conductor tracks and resistance layers applied and also prefabricated components or assemblies integrated into the circuit as SMD elements. For this the necessary contact points, conductor tracks and resistors as powdery layers of metal-containing mixtures applied to the surface of the ceramic. That can also in the Pastes are made that have the same mixture of materials as Wear emulsion.
- the permanent attachment of the very fine-grained Materials are made by baking.
- the branding or American "firing" means a process in which all components of the applied fine-grained mass with each other get connected.
- a fuse is a fuse element in air or protective gas cheaper.
- a first one as a carrier provided securing substrate and a second as a cover cap serving substrate in the form of two ceramic parts Burning in a paste for making electrical contacts metallized at opposite ends. A wire becomes fixed as a fuse between the two contacts. This Arrangement is permanently connected by gluing. A safe one electrical connection of the contacts to each other and to the Fusible conductor takes place in a final work step by soldering.
- the fastening method proposed according to the invention for Manufacture of electrical fuses involves a sintering step.
- sintering is a heat treatment described in which a powdery material mixture is not is completely melted, but only at the grain boundaries of the material mixture by diffusion and alloying connections arise.
- the resulting connection is mechanical safe and permanent and can accordingly. for fixing of a ceramic part on a fuse element of a fuse.
- she Depending on the composition of the mixture, it is also thermal resilient, higher than a variety of adhesives that commonly used to make such connections become.
- the used Parts can be tubular as well as any area his.
- ceramic materials Use in the field of electrical device fuses e.g. in the form of small pipes and flat ceramic plates with flat surface and central trough-like depression in the largest of their rectangular surface pieces.
- the electrical conductor can also pass through before the sintering process another ceramic part to be covered.
- This ceramic part only needs to be above the fusible conductor from a ground contact extend to the other and with these on the surfaces contact. So in a sintering process, namely through a single process step, substrate, Melting conductor and covering ceramic at the same time mechanically be firmly and electrically connected together.
- this arrangement has the ceramic substrate between those with sinterable Mass occupied areas on a trough-like depression.
- the covering ceramic has between those with the sinterable Earth later contacting places also one trough-like depression. So the fuse element is already at Assembly only over the two mass layers of that Substrate, and only in these places is it from the touches ceramic cover.
- the Fusible conductor at the end of the sintering process over the two new resulting electrical contact points on both sides is mechanically connected to the carrier as with the cover and is kept self-supporting. Accordingly, the fuse element only one gas layer between its connection points surrounded with great insulation and can receive the desired switching characteristics.
- the ceramic carrier the shape of a tube, which is connected to the sinterable mass is occupied.
- the fuse element is through an opening is inserted and runs from the inside of the pipe Front side to the next self-supporting and only surrounded by gas.
- the sintering process takes on the task of mechanical Attachment like the electrical contact of the Fuse element.
- the pipe openings of this embodiment can before Sintering closed on both sides by electrically conductive caps and mechanically solid and electrical in the same sintering step conductive with the tube and with the fuse element get connected. Similar measures are also with others Embodiments conceivable.
- the combination of materials is essential for the process in the sintered mass with regard to those to be joined Parts.
- the mass must have metallic components for the conductive and have mechanical connection with the fuse element.
- the components must be securely attached Mass on the surface of the ceramic of the other parts in the course enable the sintering process. So that can be used Mass to the family of "cermets", the so-called metal ceramics belong.
- this procedure is contrary to typical cermet process the powder directly, or advantageously used in the form of a paste, and not under pressed to a blank under high pressure.
- As a possible combination be the attachment of a silver wire to one Ceramic substrate using a sintered mass of silver, Called platinum and palladium.
- Fig. 1 the basic attachment of the grains is one Sintered mass from a silver-palladium-platinum mass to one Silver wire shown.
- the individual grains collide with theirs Edges and surfaces together. Sometimes they touch the surface of the silver wire. Through the sintering process there is no complete melting of those involved powdery materials, but only one Material transport between the granules, so that they attach themselves connect the contact points. Find it too Diffusion processes take place. The granules therefore lose theirs Shape not. As a result, you keep a solid and porous Mass that is well conductive and with its components the surface of the silver wire is conductively connected. In order to is a mechanically stable and electrically conductive on the wire Contact has been made.
- Fig. 2 shows an electrical fuse.
- sinterable mass 2 is applied on both sides Service.
- On the ceramic top is between the mass-coated Ends of the carrier of the fuse element 3 have been placed.
- the fuse element 3 between the contact points 4 covered by a sealing compound 5.
- This manufacturing method for easy securing advantageously just four more steps: applying the sintered mass, Inserting the fuse element, sintering and casting.
- the Work steps are metallizing, fixing and soldering omitted.
- FIG. 3 shows a particularly favorable design of an SMD fuse with a fuse element 3 in a chamber.
- ceramic substrate 1 and the cap 1 by the same shape symmetrical ceramic parts formed. With these ceramic parts only have to use the narrow side of the wider side for positioning the fuse element 3 can be distinguished over the trough 6. They are fully automatic Manufacturing no further parameters to be considered. Both parts are made on two sides with sinterable mass 2 coated and then with the between them in the Ground layer held fuse element 3 a sintering process subjected. This backup is advantageously none Post-treatment is necessary in a final step. So this process consists of only three steps. The The fuse is closed and the fuse element 3 is over the now sintered and electrically conductive contact points 4 electrically accessible.
- this fuse does not have a fixed one Upper or lower part more. You can accordingly simply through placement machines in thick-film circuits integrated or soldered as an SMD component in printed circuits become. The production costs at Manufacturing as well as the cost of using this type of fuse significantly reduced.
- Fig. 4 shows a basic design of a tube fuse with a ceramic, tubular support 7 attached to its End faces is covered with sinterable mass 2.
- the fusible conductor 3 runs from the inside of the tube Face to face. It is on each face Fusible conductor 3 in contact with the sinterable mass 2. This makes it electrically like in a sintering step mechanically connected to the contact points 4, while the Mass 2 with the surface of the ceramic carrier 7 solid is connected.
- FIG. 5 represents a supplement to the tube fuse according to FIG. 4
- the end faces of the tube 7 by metal caps 8 have been closed before the sintering process. Only from The metal caps are for the sake of clarity 8 has been shown in FIG. 5 with a large excess.
- Assembled fuse reliably with each other electrically also mechanically connected.
