Abstract
The utility model provides a planar diode's quick mounting structure, the diode include casing, anode lead and cathode lead wire, anode lead and the cathode lead wire up end that pierces through the casing and stretch into the casing in, the upper end position of anode lead and cathode lead wire still is provided with the boss, anode lead's lower extreme be connected with the buffer layer, the lower extreme of buffer layer be connected with the PN junction, the lower extreme of PN junction still be provided with a semiconductor block, the lower extreme of cathode lead wire be connected through the wire with semiconductor block, anode lead and cathode lead wire fix on the casing through the encapsulated layer that sets up. The utility model discloses a set up the buffer layer on anode lead, can be so that the resistant current rush nature of diode in the high frequency electric way be stronger to through the boss that go up to set up at the lead wire, can make the diode controlling dimension of being convenient for when installing, it is very convenient.
Description
Technical field
The utility model relates to a kind of electronic component, particularly relates to the quick attach structure of planar diode.
Background technology
Diode is a kind of electronic component with unilateal conduction, existing relatively conventional be crystal diode; When but existing crystal diode uses in high-frequency circuit, there is Reverse recovery impulse current large, easily breakdown, and existing diode is not when mounted owing to having position limiting structure, installs yardstick and is difficult to control, inconvenience very.
Summary of the invention
Main purpose of the present utility model is for prior art Problems existing, and proposes a kind of quick attach structure of planar diode.
In order to achieve the above object, the technical solution of the utility model is as follows:
Diode involved by the utility model comprises housing, anode tap and cathode leg; Described anode tap and cathode leg penetrate the upper surface of housing and extend in housing, the upper-end part of driving of anode tap and cathode leg is also provided with boss, the lower end of described anode tap is connected with resilient coating, the lower end of described resilient coating is connected with PN junction, the lower end of described PN junction is also provided with semiconductor block, the lower end of described cathode leg is connected by wire with semiconductor piece, and described anode tap and cathode leg are fixed on housing by the encapsulated layer arranged.
The contact site of described encapsulated layer and anode tap and cathode leg is also provided with encapsulation sleeve.
Described encapsulation sleeve is that insulating material is made.
Described housing is that alloy material is made.
The outer surface of described housing is also provided with fin.
The width of described boss is 2-3mm.
The beneficial effects of the utility model are: the utility model by arranging resilient coating on anode tap, the resistance to rush of current of diode in high-frequency circuit can be made stronger, and by the boss arranged on lead-in wire, diode can be made to be convenient to controlling dimension when mounted, very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1 is housing, 2 is semiconductor piece, and 3 is PN junction, and 4 is resilient coating, and 5 is anode tap, and 6 is cathode leg, and 7 is encapsulation sleeve, and 8 is encapsulated layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, the diode involved by the utility model comprises housing 1, anode tap 5 and the cathode leg 6 that alloy material is made, anode tap 5 and cathode leg 6 penetrate the upper surface of housing 1 and extend in housing 1, the upper-end part of driving of anode tap 5 and cathode leg 6 is also provided with the boss that width is 2-3mm, the lower end of anode tap 5 is connected with resilient coating 4, the lower end of resilient coating 4 is connected with PN junction 3, the lower end of PN junction 3 is also provided with semiconductor block 2, the lower end of cathode leg 6 is connected by wire with semiconductor piece 2, anode tap 5 and cathode leg 6 are fixed on housing 1 by the encapsulated layer 8 arranged, the contact site of encapsulated layer 8 and anode tap 5 and cathode leg 6 is also provided with the encapsulation sleeve 7 that insulating material is made, the outer surface of housing 1 is also provided with fin 9.
The present embodiment, by arranging resilient coating on anode tap, can make the resistance to rush of current of diode in high-frequency circuit comparatively strong, and the boss by arranging on lead-in wire, diode can be made to be convenient to controlling dimension when mounted, very convenient.
