Description
Technical field
The utility model relates to a kind of axial diode, is specifically related to a kind of for solar photovoltaic cell panel assembly/or the axial diode of applied environment high-temperature.
Background technology
The insulating cement outer surface of existing axial diode is smooth/rounded column, during use, be mounted in the terminal box being connected with solar photovoltaic cell panel assembly or in high-temperature applied environment, but the axial diode of this structure is when work, can produce high temperature, and the high temperature producing exceedes the junction temperature of the diode chip for backlight unit of axial diode, make product failure.
Summary of the invention
The purpose of this utility model is: not only good heat dissipation effect of one is provided, and the high axial diode of reliability, to overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model: a kind of axial diode, comprise the first lead-in wire, the second lead-in wire, diode chip for backlight unit and insulating cement, described the first lead-in wire and second goes between and has separately and its first paster Ji Dao and the second paster Ji Dao of one each other, the positive pole of diode chip for backlight unit is by soldering paste and the first paster Ji Dao welding, the negative pole of diode chip for backlight unit is by soldering paste and the second paster Ji Dao welding, described the first paster Ji Dao, the second paster Ji Dao and diode chip for backlight unit are injection-moulded in insulating cement, and its: the periphery of described insulating cement has radiating groove.
In technique scheme, the radiating groove of described insulating cement periphery is the axial radiating groove of arranging along its length.
In technique scheme, the radiating groove of described insulating cement periphery is the circular radiating groove of along the circumferential direction arranging.
In technique scheme, the radiating groove of described insulating cement periphery is helical form radiating groove.
In technique scheme, the bottom land of the radiating groove of described insulating cement periphery is roughness.
In technique scheme, described the first lead-in wire and have the first boss radially near the first paster Ji Daochu, the second lead-in wire and have the second boss radially near the second paster Ji Daochu, described first radially boss and second radially boss be all positioned at insulating cement.
The good effect that the utility model has is: owing to adopting after above-mentioned axial diode structure, because the periphery of described insulating cement has radiating groove, so just increased the surface area of insulating cement, namely increased the area of dissipation of diode chip for backlight unit, make good heat dissipation effect, reduced the temperature of axial diode when work, can effectively reduce failure rate, extended useful life, again because the periphery of described insulating cement has radiating groove, so just reduced the use amount of insulating cement, not only reduced production cost, and make the smaller volume of axial diode, corresponding the reducing of the suffered stress of diode chip for backlight unit, improved the reliability of axial diode work.Realized the purpose of this utility model.
