Description
Technical field
This utility model belongs to inverter technology field, specifically refers to a kind of jamproof inverse
Become device power module.
Background technology
Inverter is that direct current energy (battery, accumulator jar) is transformed into alternating current (generally
220V, 50Hz are sinusoidal wave), it is made up of inverter bridge, control logic and filter circuit.Extensively
Be applicable to air-conditioning, home theater, electric wheel, electric tool, sewing machine, DVD, VCD,
Computer, TV, washing machine, smoke exhaust ventilator, refrigerator, videocorder, masseur, fan, photograph
Bright etc., go out work abroad because the popularity rate of automobile is higher or out on tours i.e. can use inverter
Connect battery band galvanic electricity device and various tool work.The vehicle-mounted inversion exported by cigar lighter is
20W, 40W, 80W, 120W to 150W power requirements；Larger power
Inverter connecting line to be passed through is received on storage battery.Household electrical appliance are connected to power supply changeover device
Outfan just can use various electrical equipment in automobile.Spendable electrical equipment has: mobile phone, notebook
Computer, DV, camera, illuminating lamp, electric shaver, CD player, game machine,
Palm PC, electric tool, car refrigerator and various tourism, camp, medical first aid electrical equipment etc..
Metal-oxide-semiconductor on the motherboard of current inverter generally uses welding or SMT technology
Conforming on PCB, on it, three pins (G pole, D pole and S pole) are arranged side by side, phase
Away from nearer, it is easy to blasted pipe phenomenon occurs owing to misleading, its interference performance and protrusion-dispelling wave energy
Power is the most weak.
Utility model content
This utility model is in order to overcome the deficiency of prior art, it is proposed that a kind of jamproof inverse
Become device power module.
This utility model solves above-mentioned technical problem by following technical proposals.
A kind of jamproof inverter power supply module, including radiator, is fixedly installed to heat radiation
The radiating aluminium sheet of device, be fixedly installed to radiating aluminium sheet multiple metal-oxide-semiconductors and with multiple MOS
The power module pcb board of pipe electrical connection, the pin of the plurality of metal-oxide-semiconductor is the most successively
For G pole, D pole and S pole, its middle D pole pin is set with magnet ring.
More specifically, described radiator includes aluminium base, and described aluminium base side is provided with multiple
The radiating fin being spacedly distributed, described radiating aluminium sheet is screwed to another of aluminium base
Side.
More specifically, described metal-oxide-semiconductor is screwed to radiating aluminium sheet.
More specifically, described magnet ring is arranged on what D pole pin was connected with power module pcb board
Bottom.
More specifically, the quantity of the plurality of metal-oxide-semiconductor is 6.
The G pole of the metal-oxide-semiconductor of the power supply mainboard of conventional inverter, D pole and S pole set side by side
Putting, position is close, once occurs misleading, it is easy to bombing occurs, compared with conventional art,
This utility model is by arranging outside the D pole pin in the middle of the metal-oxide-semiconductor of inverter power supply module
There is magnet ring, there is stronger Anti-Jamming and surge prevention effect, it is to avoid misleading produces
Blasted pipe phenomenon, substantially increases the reliability of inverter work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Provide this utility model preferred embodiment below in conjunction with the accompanying drawings, new to describe this practicality in detail
The technical scheme of type.
Such as Fig. 1, a kind of jamproof inverter power supply module, including radiator 1, fixing peace
The radiating aluminium sheet 2 being filled to radiator 1, six metal-oxide-semiconductors being fixedly installed to radiating aluminium sheet 2
4 and the power module pcb board 3 that electrically connects with six metal-oxide-semiconductors 4, described six MOS
The pin of pipe 4 is followed successively by G pole 41, pole 43, D pole 42 and S, its middle D from left to right
It is set with magnet ring 5 on the pin of pole 42.
Wherein, radiator 1 include aluminium base, described aluminium base side be provided with multiple at equal intervals
The radiating fin 10 of distribution, described radiating aluminium sheet 2 is screwed to another of aluminium base
Side.
Wherein, metal-oxide-semiconductor 4 is screwed to radiating aluminium sheet.
Wherein, magnet ring 5 is arranged on what D pole 42 pin was connected with power module pcb board 3
Bottom.
The present embodiment is managed by the D pole 42 in the middle of the metal-oxide-semiconductor 3 of inverter power supply module
Arranging magnet ring 5 outside foot, this magnet ring 5 has stronger Anti-Jamming and surge prevention effect, keeps away
Exempt from the blasted pipe phenomenon produced that misleads, substantially increase the reliability of inverter work.
Although the foregoing describe detailed description of the invention of the present utility model, but the skill of this area
Art personnel should be appreciated that these are merely illustrative of, and protection domain of the present utility model is by institute
