The circuit board that components and parts are installed has two apertures to give the capacitor plug-in mounting, and this installation form manufacturability is poor, can not tolerate high mechanical oscillation or impact, and because lead-in inductance, the frequency of utilization upper limit is restricted.The development trend that be to adapt to miniaturization, slimming, the electronic component structure form is changed into surface card dress (SMT) and is become irresistible trend by being used for traditional plug-in.Chip multilayer ceramic capacitor can satisfy the needs that SMT mounts production, it can be made into high pressure larger capacity capacitor, has certain difficulty but make than the capacitor of low capacity, and its process equipment and technology want complicated a lot, cause industrialization cost height, selling price is also high.Under this background, our company's independent development chip individual layer high-voltage ceramic capacitor, and utility application has been proposed on April 29th, 2002, now obtained the utility model patent (patent No.: ZL02227213.5) that State Intellectual Property Office authorizes.
In this patent, our company has designed chip high-voltage ceramic capacitor (70), as shown in Figure 1, its structure is by silver-colored ceramics (10), mould shell (71) and two lead-out wires (21,31), by the tow sides silver electrode (11 of silver-colored ceramics (10), 12) be welded with lead-in wire (21 on respectively, 31), moulding shell (71) is sealing by silver-colored ceramics (10) and is being welded in by the lead-in wire (21 on the silver-colored ceramics (10), 31) a end, moulded shell (71) by silver-colored ceramics (10) and sealed back formation cube shaped, lead-in wire (21,31) be flat, lead-in wire (21,31) be exposed to the end edge of moulding outside the shell (71) and mould shell (71) bending, its termination is fixed on the same plane of moulding shell (71).Mould shell (71) and adopt epoxy resin, go between (21,31) but the employing conducting metal.
For realizing the industrialization production of this product, our company has developed the method for manufacturing technology of sheets type ceramic dielectric capacitor specially, and the disjunctor lead-in wire is introduced in its production technology.
The utility model content:
The purpose of this utility model just be to provide can a kind of new construction lead-in wire, can realize the mass automatic production of product.
The utility model is achieved by the following technical solution: the disjunctor lead-in wire (30) of sheets type ceramic dielectric capacitor, it is characterized in that: it comprises disjunctor bar (36), extend equidistant identical lead-in wire (31) in the same side of disjunctor bar (36), between the solder side (33) of lead ends (32), become π shape bending (34) downwards.
