Abstract
The utility model relates to the technical field of electronic components, and comprises a silver-plated ceramic chip (1), a plastic case (2), and two lead-out wires (3, 4). The utility model is characterized in that the lead-out wires (3,4) are respectively welded on the front and the reverse faces of the silver-plated ceramic chip (1), the plastic case (2) is encapsulated on the silver-plated ceramic chip (1) and is welded at one ends of the lead-out wires (3,4) which are welded on the silver-plated ceramic chip (1), the silver-plated ceramic chip (1) is encapsulated by the plastic case (2) to form a cubic type, the lead-out wires (3,4) are taken in a flat type, one ends of the lead-out wires (3,4) are exposed outside the plastic case (2) to be bended along the plastic case (2), the ends are fixed on the same plane of the plastic case (2), the plastic case (2) adopts the epoxy resin, and the conductive metal is adopted by the lead-out wires (3, 4). A slice ceramic capacitor is manufactured into a monolithic shape, the appearance is normalized, and the slice ceramic capacitor can be directly mounted on a wiring board without the need of being plugged-in like a disk ceramic capacitor and is more suitable for the highly efficient SMT parallel-placement production. Meanwhile, the structure is simple, the productive technology equipment and the technology are simpler than that of the slice multiple-layer ceramic capacitor, and the industrialized fabrication cost and the selling price are low.
Description
Technical field:
The utility model relates to the electronic component technology field, refers in particular to a kind of chip high-voltage ceramic capacitor.
Background technology:
The high-voltage ceramic capacitor of producing has disk high-voltage ceramic capacitor, chip multilayer ceramic capacitor etc. at present.The disk high-voltage ceramic capacitor is a traditional structure, the ceramic two thin long leads of being burn-on on the silver strip, and one deck epoxy resin is wrapped on the surface, and the circuit board of installation has two apertures to give the capacitor plug-in mounting.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.For adapting to the development trend of miniaturization, slimming, the electronic component structure form is changed into the SMT mounted type by traditional plug-in becomes irresistible trend.Chip multilayer ceramic capacitor can satisfy the needs that SMT mounts production, as shown in Figure 1, it is superimposed as sheet by ceramic membrane (10), two ends apply external electrode (20,30), it can be made into high pressure larger capacity capacitor, make than the capacitor of low capacity to have certain difficulty, and its process equipment and technology wants complicated a lot, cause industrialization cost height, selling price is also high.Under this background, the utility model also just arises at the historic moment.
Summary of the invention:
The purpose of this utility model just is to provide a kind of new construction of ceramic capacitor, and this capacitor comprises that its lead-in wire forms a smooth monolithic shape, and it is simple to produce the process equipment and the technology of this ceramic capacitor, is suitable for industrialization large-scale production.
The utility model is achieved by the following technical solution: the chip high-voltage ceramic capacitor, comprise by silver-colored ceramics, mould shell and two lead-out wires, be welded with lead-out wire on the tow sides of silver-colored ceramics respectively, moulding shell is sealing by silver-colored ceramics and being welded in by an end of the lead-out wire on the silver-colored ceramics, it is characterized in that: moulded shell by silver-colored ceramics and seal back formation cube shaped, lead-out wire is flat, and lead-out wire is exposed to moulds the outer end of shell along moulding the shell bending, and its termination is fixed on the same plane of moulding shell.
Mould shell and adopt epoxy resin; But lead-out wire adopts conducting metal.
Like this, sheets type ceramic dielectric capacitor is made the monolithic shape, and neat appearance can directly be laid in the circuit board, need not plug-in mounting as the disk ceramic capacitor, is more suitable for high efficiency SMT and mounts production.Simultaneously, because its is simple in structure, production process equipment and technology are simple than chip multilayer ceramic capacitor, and the industrialization cost is low, and selling price is also low.
Description of drawings:
Accompanying drawing 1 is the schematic diagram of chip multilayer ceramic capacitor
Accompanying drawing 2 is one of stereogram of the present utility model
Accompanying drawing 3 is two of a stereogram of the present utility model
Accompanying drawing 4 is the utility model A-A profile in Fig. 2
Embodiment:
See shown in the accompanying drawing 2～4, the utility model comprises by silver-colored ceramics (1), mould shell (2) and two lead-out wires (3,4), be welded with lead-out wire (3 on the tow sides of silver-colored ceramics (1) respectively, 4), moulding shell (2) is sealing by silver-colored ceramics (1) and is being welded in by the lead-out wire (3 on the silver-colored ceramics (1), 4) a end, it is characterized in that: moulded shell (2) by silver-colored ceramics (1) and seal back formation cube shaped, lead-out wire (3,4) be flat, lead-out wire (3,4) be exposed to the end edge of moulding outside the shell (2) and mould shell (2) bending, its termination is fixed on the same plane of moulding shell (2).
Mould shell (2) and adopt epoxy resin; Lead-out wire (3,4) but adopt conducting metal.
Like this, sheets type ceramic dielectric capacitor is made flat monolithic shape, and neat appearance can directly be laid in the circuit board, need not plug-in mounting as the disk ceramic capacitor, is more suitable for high efficiency SMT and mounts production.And this structure capacitive device frequency characteristic is good than the disk ceramic capacitor, and the high-voltage capacitor of making than low capacity is easier to, simultaneously, because its is simple in structure, production process equipment and technology are simple than chip multilayer ceramic capacitor, and the industrialization cost is low, and selling price is also low.
It is applicable to the buffer circuit of balancing circuitry, Switching Power Supply of notebook computer, LCD backlighting inverter and other high-tension circuits etc.
