Description
Technical Field
The utility model relates to a diode installation technical field specifically is an install radiator structure of fast recovery diode.
Background
Among electronic components, a diode is a device having two electrodes, which only allows current to flow in a single direction, and many applications use the rectifying function. The Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time, is mainly applied to electronic circuits such as a switching power supply, a PWM (pulse width modulation) and a frequency converter, and can be used as a high-frequency rectifier diode, a freewheeling diode or a damping diode. Because of its rectification function, the fast recovery diode is mainly used as a rectification element in an inverter power supply and is often installed on a radiator of an electric welding machine. When installing fast recovery diode on the radiator, the pin need overlap earlier and bend into 90 and insert the downthehole welding of circuit board welding after the protective sheath, as shown in fig. 1-4, fast recovery diode 1's pin needs bend 90, including pin protective sheath 9, use elasticity bending sheet 4 or the first screw 7 of elasticity combination preforming 8 cooperation to be fixed in the surface of radiator 3, then install circuit board 5 on radiator 3, make the alignment pin of the welding hole on the circuit board 5 let the pin insert, 6 are the insulated column in the picture, bend into 90 installation with the straight tube foot because of needs, waste time and energy during the production operation, be not convenient for improve workshop production efficiency, and cause the diode damage easily when bending.
Disclosure of Invention
In order to solve the problem that the current fast recovery diode installation effectiveness is low, the utility model provides an install fast recovery diode's radiator structure, its installation effectiveness that can effectively improve fast recovery diode improves fast recovery diode's reliable stability.
The technical scheme is as follows: the utility model provides an install radiator structure of fast recovery diode, its includes the radiator, install fast recovery diode and circuit board on the radiator, its characterized in that, the radiator surface is provided with the boss, is located the boss inboard the radiator surface is provided with the insulated column, the circuit board through with the first fix with screw of insulated column complex is inboard the boss, be provided with on the boss fast recovery diode, fast recovery diode's straight tube foot tip is pasted welding hole on the circuit board.
The fast recovery diode is further characterized in that ceramic gaskets are arranged between the fast recovery diode and the surface of the boss, and heat-conducting silica gel layers are arranged between the back surface of each ceramic gasket and the surface of the boss and between the fast recovery diode and the front surface of each ceramic gasket;
and the fast recovery diode is matched and fixed with the second screw through the elastic bending piece.
Adopt the utility model discloses afterwards, the pin of fast recovery diode need not bend, directly can be connected with the circuit board with the straight tube foot originally, and easy operation is convenient, can not cause the damage to diode itself, and the effectual installation effectiveness who improves the fast recovery diode has improved the reliable stability of fast recovery diode.

Detailed Description
See fig. 5 to 8, a install radiator structure of fast recovery diode, it includes radiator 3, install fast recovery diode 1 and circuit board 5 on the radiator 3, radiator 3 surface is provided with two rows of bosss 10, it is provided with insulated column 6 to be located two inboard heat radiator 3 surfaces of boss 10, circuit board 5 is fixed in boss 10 inboardly through the first screw 7 with insulated column 6 complex, be provided with fast recovery diode 1 through insulating gasket 2 on the boss 10, between 2 backs of ceramic gasket and the boss 10 surface, all be provided with the heat conduction silica gel layer between fast recovery diode 1 and the ceramic gasket 2 front, can realize the veneer, the straight tube foot tip of fast recovery diode 1 pastes the welding hole on circuit board 5, the connection can be realized to the lug weld. The fast recovery diode 1 is fixed by the elastic bending piece 4 and the second screw 11.
The installation steps are as follows:
(1) the back of the fast recovery diode 1 is coated with heat-conducting silicon and glued with the upper surface of the ceramic gasket 2;
(2) the back of the ceramic gasket 2 is coated with heat-conducting silicon and is glued with a boss 10 of the radiator 3;
(3) the circuit board 5 is arranged between the two bosses 10 through the insulating column 6 and the first screw 7;
(4) the elastic pressing sheet 4 compresses the front surface of the fast recovery diode 1 through the second screw 11, so that the straight tube pin is tightly attached to the welding hole of the circuit board 5 for direct welding and firmness.
The fast recovery diode needing cooling and heat dissipation is generally packaged by adopting TO-220 or TO-247, in the embodiment, the type of the fast recovery diode is IDW100E60, the packaging type is TO-247, as shown in fig. 7, the heat dissipation surface of the fast recovery diode is parallel TO the pin, the pin does not need TO be bent, the pin is directly and firmly welded with a welding hole of a circuit board, time and labor are saved, the pin breakage loss of the fast recovery diode is effectively reduced, and the reliability and the stability of the fast recovery diode are improved.
