Description
Technical field
The utility model modular assembly relates to a kind of electrical appliance module structure, is widely used in inversion products, can be used for welding machine, and the electrodeposit power supply also can be used for frequency converter, and direct current machine drags etc.
Background technology
Modular assembly is as electric component, is to have certain requirements to its moisture resistance, anticorrosion, dustproof, antistatic and shock resistance, to guarantee electrical equipment stability and security reliability.External IGBT module costs an arm and a leg, processing environment and specification requirement are all very strict, so cost is higher.
Summary of the invention
The problem that the utility model need solve is: a kind of modular assembly is provided so that guarantee to have protection against the tide under the prerequisite of electrical property, anticorrosion, dustproof, antistatic and characteristics cheaply.
The utility model provides following technical proposals for addressing the above problem: a kind of modular assembly, comprise the wiring board of housing, dividing plate and plug-in module component palette, and wherein, described housing is a semi-closed structure, establishes rubber slab in the circuit board.The utlity model has protection against the tide, anticorrosion, dustproof, antistatic and advantage such as shockproof.
Described housing and dividing plate adopt working of plastics, the easy and good insulating of moulding.
On described wiring board, stamp the thick room temperature vulcanized silicone rubber in the 15-25mm left and right sides.
The utility model provides a kind of IGBT module, described modular assembly plate is connected with master board, this modular assembly plate adopts the principle of full-bridge inverting and designs, there are eight 40T120IGBT pipes inside, per two IGBT pipes are one group, be divided into four groups, two IGBT pipes of every group are connected in parallel, and reach 80A during 100 ℃ of rated current.In addition, rated voltage is 1200V, and the ideal operation frequency range is 15Hz～20KHz.Be mainly used in inversion products, can be used for welding machine, the electrodeposit power supply also can be used for frequency converter, and direct current machine drags etc.
Described modular assembly plate has 4 groups of external connections and two connection bolts, comprising: temperature switch line, promotion line, input electrode line, input negative line and output terminal bolt.The temperature switch line is received in the machine master board, to realize the purpose of temperature protection; Promoting line also is to join with the master board of machine, and purpose is for the IGBT pipe in this modular assembly plate provides promotion, to realize the PWM switch performance of IGBT; The main circuit of input electrode line and input negative line and machine joins, to obtain operating voltage; Output terminal bolt joins with the elementary line of the main transformer of machine, and the direct current square-wave voltage that goes out through full-bridge inverting is provided for machine.
Superiority of the present utility model is: with low cost, functional, the machine-shaping instrument is easy to get,, it is relatively low that processing environment requires, and prepared product has protection against the tide, anticorrosion, dustproof, antistatic, antiknock quality.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.

Embodiment
Shown in accompanying drawing 1 the utility model appearance structure schematic diagram, have semienclosed outward appearance, peripheral fix and completely cut off, so handle and the voltage endurance capability of entire product is also significantly improved with mould of plastics.Modular assembly comprises semi-enclosed housing, is used for the dividing plate of placement module component palette, and establishes rubber slab in the circuit board, makes to the utlity model has protection against the tide, anticorrosion, dustproof, antistatic and advantage such as shockproof.
Described housing and dividing plate adopt working of plastics, the easy and good insulating of moulding.
On described wiring board, stamp the thick room temperature vulcanized silicone rubber in the 20mm left and right sides.
Accompanying drawing 2 the utility model are used for shown in the stick arc welder main circuit diagram of welding machine, the modular assembly plate is connected with master board, this modular assembly plate adopts the principle of full-bridge inverting and designs, there are eight 40T120IGBT pipes inside, per two IGBT pipes are one group, are divided into four groups, and two IGBT pipes of every group are connected in parallel, in the time of 100 ℃, rated current reaches 80A.In addition, rated voltage is 1200V, and the ideal operation frequency range is 15Hz～20KHz.
Though the present embodiment volume is big slightly, and is with low cost, functional, machining tool is very common, and it is relatively low that processing environment requires, with respect to external IGBT module cost an arm and a leg, processing environment and specification requirement Gao Eryan very all, have high cost performance, meet the real national conditions of China.
