Definitions

  • This invention relates to a chip-type fuse for interrupting overcurrents which damage electronic parts mounted on a printed circuit board (PCB), and more particularly, to an improved chip-­type fuse which is inexpensive and can be easily automatically monted on a PCB.
  • PCB printed circuit board
  • a fuse is used to inrterrupt overcurrents which damage electronic parts mounted on a PCB.
  • chip-­type fuses which are mounted on a PCB have been developed in recent years.
  • One of the conventional chip-type fuses includes an insulating substrate and a conductor.
  • the insulating substrate has two electrodes disposed thereon, and the conductor electrically connects the two electrodes to each other.
  • the conductor is made of thin-film metal and disposed in a recess formed on the lower surface of the substrate.
  • Another conventional chip-type fuse includes an insulating substrate having a pair of electrodes, a gold (Au) wire wire-­bonded to the electrodes, and a resin which is disposed on the substrate to seal the gold wire.
  • the conventional fuses are very expensive because the recess for housing the conductor must be formed or the wire must be wire-bonded to the electrodes. In addition, the conventional fuses have so complicated shapes that they can not easily automatically mounted on a PCB.
  • a chip-type fuse which includes (1) an insulating member, (2) a pair of electrode members which are made of thin-film metal and disposed on the insulating member, (3) a conducting member which is formed on the upper surface of the insulating membear and electrically connects the pair of electrode members to each other, and (4) a protecting member disposed on the insulating member for protecting the conducting member.
  • Figs. 1 and 2 show a chip-type fuse according to a first embodiment of the invention.
  • a chip-type fuse 1 includes a ceramic substrate 2 as an insulating substrate which is rectangular like a rectangular chip-type resistor and whose size is 3.2mm(l1) x 1.6mm(l2).
  • a conducting member 3 made of thin-film metal which is deposited or printed on upper surface 2a.
  • Conducting member 3 can be made of a silver-­palladium (Pd) alloy, silver-platinum (Pt) alloy, silver, copper, or gold.
  • Electrodes 4a and 4b are formed on side ends 2b and 2c of substrate 2, respectively. Electrodes 4a and 4b are made of thin-film metal which is deposited on side ends 2b and 2c or disposed theron with other known methods.
  • Conducting member 3 is a ractangular parallelepiped and both ends 3a and 3b are connected to electrodes 4a and 4b, respectively.
  • Upper surface 2a of substrate 2 is coated with a silicone resin film (protecting film) 5 to completely cover conducting member 3.
  • chip-type fuse 1 Since chip-type fuse 1 has the same shape as micro-chip resistors, it can be easily automatically mounted on a PCB to perform the mounting cost.
  • fuse 1 The operation of fuse 1 is descrived hereinafter.
  • conducting member 3 If an overcurrent flows through fuse 1, conducting member 3 is melted and broken somewhere between ends 3a and 3b to interrupt the overcurrent. Since conducting member 3 is covered with silicone resin film 5, metal vapor generated at the melted portion are prevented from scattering outside fuse 1. Moreover, arc discharge caused by the metal vapor is prevented from continuing because the silicone resin functions as an arc-­extinguishing medium, completely protecting the electronic parts. In addition, since conducting member 3 is formed directly on upper surface 2a of substrate 2, it has a high heat-radiating effect to allow flows of high-level currents despite the small size of fuse 1.
  • conducting member 3 is not made of a golden wire unlike the conventional chip-type fuse, conducting member 3 is hardly broken, easy to handle, and highly heat-­resistant.
  • Fig. 3 shows a chip-type fuse according to a second embodiment of the invention.
  • a chip-type fuse 11 has a ceramic substrate 12 as an insulating substrate having the size of 3.2mm x 1.6mm which is equal to that of fuse 1 according to the first embodiment.
  • Side ends 12b in the longitudinal direction respectively have semicircular holes 12c which extend through in height.
  • a rectangular conducting member 13 is deposited or printed on an upper surface 12a of substrate 12.
  • Conducting member 13 has trimmed portions 13b which are trimmed with laser light to obtain appropriate resistance.
  • Electrodes 14 are formed on side ends 12b of substrate 12, respectively. Electrodes 14 are made of thin-­film metal as electrodes 4a and 4b described in the first embodiment. Ends 13a of conducting member 13 are connected to electrodes 14.
  • Upper surface 12a of substrate 12 is coated with a silicone resin film (protecting film) 15 to completely cover conducting member 13.
  • chip-type fuse 11 The operation of chip-type fuse 11 is described hereinafter.
  • fuse 11 If an overcurrent flows through fuse 11, one of trimmed portions 13b is melted and broken to interrupt the overcurrent. The reliability of fuse 11 increases because trimmed portions 13b are easily melted and broken by an overcurrent.
  • conducting members 3 and 13 are rectangular in all the embodiments, they can have another shape.
  • protecting films 5 and 15 can be made of a glass material.
