Abstract
The utility model discloses a suspended fuse wire type surface mounting fuse. A fuse wire plate is arranged in the fuse in a split manner, namely a first metal base plate, a second metal base plate and a fuse wire are arranged independently; and then two ends of the fuse wire are respectively connected to the first metal base plate and the second metal base plate (for example, adopting a welding mode) to form the fuse wire plate. Therefore, the fuse wire plate is easy to process, and the shortcoming that the fuse wire plate is thin is overcome; and the thickness of the fuse wire in the fuse wire plate can be controlled according to a performance requirement on the fuse; furthermore, the fuse wire can be made into any required shape, such as a dual-linear shape, a spiral shape, an S shape, a flat shape and the like; the two ends of the fuse wire are connected to the two metal base plates, so the line surface connection is realized. The fuse wire is manufactured independently, so the processing error (between 1 and 4 %) can be reduced, and the processing precision is improved.
Description
Technical field
the utility model relates to unsettled fuse-type surface mounting fuse protector.
Background technology
are along with science and technology development; Electric power/electronic product is variation, complicated day by day; The simple glass tube fuse that applied circuit protecting element is non-in the past, but developed into a new electronic component field of a great variety.Surface mounting fuse protector is applicable to compact conformation as a kind of frivolous little new-type element, and in the protective circuit of each electronic product that volume is small, its application is boundless.
Main two major types that fuse of
unsettled fuse-type and solid state device type fuse are present small-sized surface mounting fuse protector.The midget fuse of unsettled fuse-type is that fuse (lead) is suspended in the shell of hollow.Because the thermal transmission coefficient of air is much littler than most solid, therefore the fuse of unsettled fuse-type just can be with fuse failure than the less energy of fuse needs of solid state device type, and its resistance can also be less.
The AirMatrix of
company series midget fuse is that fuse (lead) is suspended in the shell of hollow, has advantages such as resistance is little, power consumption is low, and can be through corresponding method of manufacture fast, produce in large quantities.
The reliability that
fuse (lead) manufacturing approach and the mode of laying thereof are connected with the termination is the important indicator of the fuse of unsettled fuse-type.
traditional fuse (lead) adopts copper cash or alloy wire to form the line in needed various lines footpath with the mode of wire drawing; And it is distributed in the cavity (glass tube or earthenware); And make it to realize being connected through soldering paste with termination (metal cap), the shortcoming of this design is that fuse is difficult to be fixed on the centre of cavity and has to contact with cavity wall.
are connected fixing improving one's methods with fuse and are to use fuse extended to and outerly constitute a some ways of connecting with termination electrode or coating with the termination.This design shortcoming is that a connection contact area is little, and the back easy fracture that expands with heat and contract with cold, and connection reliability is not good.What existing connectivity was done better is: japanese announces that JP2006-244948 has disclosed the method with the unsettled fuse of the superimposed making of two-tier circuit plate (lead) type surface mounting fuse protector.The fuse that this method is made has fuse and extends to the characteristic beyond the shell; The two ends of fuse only form Three-dimension Contact through end face and coated electrode; But this mode needs boring earlier bonding again; Can cause a part of glue to outflow toward the hole and covering the end of a thread along line, influential to the stability and the outward appearance of product electrical property.
BP GB2410627A discloses and has adopted the fuse of thin copper foil as fuse board; The thin copper foil integral production becomes the I type; Two ends have the backing plate of broad, and narrower fuse is arranged between the backing plate of two ends broad, and the fuse both ends of the surface have electroplates the end electrode that forms; The end electrode at two ends is connected through the face face with the backing plate at fuse board two ends respectively; Guaranteed the reliability that connects like this, both avoided the some connection reliability not good, avoided three-dimensional connection glue again along the harmful effect of line past hole outflow to the stability and the outward appearance of product electrical property.But because fuse board adopts the machine-shaping of thin copper foil one; Fuse board generally can only be done very thinly, can only be used to form low peace fuse, and the too thin processing of fuse board also is difficult for; The machining accuracy error is big (error is 5% ~ 10%); And fuse board one processing causes fuse generally can only can't form other shapes such as spirality for linear, can't satisfy the diversity requirement.
