Description
Technical field
The utility model relates to a kind of parts of inverter, is specifically related to a kind of rack inverter case with input and output mistake proofing plug.
Background technology
Inverter direct current energy (battery, accumulator jar) is transformed into alternating current (be generally 220V, 0Hz is sinusoidal wave), it is made up of inverter bridge, control logic and filter circuit, be widely used in air-conditioning, home theater, electric wheel, electric tool, sewing machine, DVD, VCD, computer, TV, washing machine, smoke exhaust ventilator, refrigerator, video tape recorder, massager, fan, illumination etc.Abroad because popularity rate higher the go out work or out on tours and available inverter of automobile connect storage battery drive electrical equipment and various tool work.
Rack integrated machine for reverse conversion is the common a kind of assembling form of inverter, its structure generally as DVD projector in rectangular structure.The all built-in many metal ferrules be parallel to each other of existing rack inverter input and output plug, this just makes input and output plug the same from the appearance, is difficult to divide equally; Generally adopt and remind word to be described at corresponding plug place engraving or printing, but along with the continuous increase in rack integrated machine for reverse conversion useful life, its engraving or the word printed fuzzy or peel off gradually, be easy to the plug causing cable inserting error, therefore there is certain potential safety hazard.
Utility model content
The utility model object provides a kind of rack inverter case with input and output mistake proofing plug to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rack inverter case with input and output mistake proofing plug, in cuboid-type, its side is provided with from top to bottom and exchanges output protection end, exchanges input protection end and ground protection end, this side is also provided with two current input terminals, two ac output ends and a 12V DC output end, described current input terminal internal fixtion has contact pin mounting panel and parallel three contact pins be arranged in contact pin mounting panel, and described contact pin is equilateral triangle arrangement; Described ac output end internal fixtion has jack mounting panel and parallel three jacks be arranged in jack mounting panel, and described jack is equilateral triangle arrangement.
Optimally, described jack mounting panel protrudes from rack inverter case, and described contact pin mounting panel falls into and is located in rack inverter case.
Optimally, three projections for blocking cable are provided with in described current input terminal, ac output end and 12V DC output end.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model is with the rack inverter case of input and output mistake proofing plug, by arranging three contact pins at current input terminal internal fixtion contact pin mounting panel and arrange three jacks at ac output end internal fixtion jack mounting panel, effectively can distinguish current input terminal and ac output end like this and can not by cable wrong plug, and do not weaken along with the use of rack inverter case, effectively prevent the generation of potential safety hazard.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model with the rack inverter case of input and output mistake proofing plug;
Wherein, 1, rack inverter case; 2, output protection end is exchanged; 3, input protection end is flowed; 4, ground protection end; 5, current input terminal; 51, contact pin mounting panel; 52, contact pin; 6, ac output end; 61, jack mounting panel; 62, jack; 7,12V DC output end; 8, protruding.
Embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail:
The rack inverter case with input and output mistake proofing plug as shown in Figure 1, in cuboid-type, is mainly provided with and exchanges output protection end 2, exchanges input protection end 3, ground protection end 4, current input terminal 5, ac output end 6 and DC output end 7.
Wherein, output protection end 2 is exchanged for providing protection to the output of alternating current; Exchange input protection end 3 for providing protection to the input of alternating current; Ground protection end 4 is for providing ground protection; They are arranged on the side of rack inverter case 1 from top to bottom.Current input terminal 5, ac output end 6 and DC output end 7 are also arranged on same side, current input terminal 5 has two, its internal fixtion has contact pin mounting panel 51 and parallel three contact pins, 52, three contact pins 52 arrangement in equilateral triangle be arranged in contact pin mounting panel 51; Ac output end 6 also has two, and its internal fixtion has jack mounting panel 61 and parallel three jacks, 62, three jacks 62 also arrangement in equilateral triangle be arranged in jack mounting panel 61; DC output end 7 is one, and its internal fixtion has jack mounting panel and parallel two jacks be arranged in jack mounting panel, and two jacks are in same level.By arranging three contact pins 52 and arrange three jacks 62 at ac output end 6 internal fixtion jack mounting panel 61 at current input terminal 5 internal fixtion contact pin mounting panel 51, effectively can distinguish current input terminal 5 and ac output end 6 like this and can not by cable wrong plug, and do not weaken along with the use of rack inverter case, effectively prevent the generation of potential safety hazard.
In the present embodiment, jack mounting panel 61 protrudes from rack inverter case 1, and contact pin mounting panel 51 falls into be located in rack inverter case 1, and this is conducive to distinguishing current input terminal 5 and ac output end 6 further, cable wrong plug can be prevented, avoid the generation of potential safety hazard.Three projections 8 (three projections 8 are dispersed in same circle) for blocking cable are provided with in current input terminal 5, ac output end 6 and 12V DC output end 7, thus improve the ability of current input terminal 5, ac output end 6 and 12V DC output end 7 securing electric lines cable, prevent electric wire cable from fixing loosely and the landing or exposed that occurs, reduce dangerous probability.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection range of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
