Specific embodiment

To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to Specific embodiment and Detailed description of the invention, the preferred embodiment that the present invention is further explained.

Embodiment

Fig. 1-Fig. 6 is please referred to, the present invention provides a kind of multifunction micro transformer, and structure includes shell 1, dissipating cover shell 2, magnetic core 3, block tin 4, draw pin 5, the inside center of the shell 1 are equipped with folded magnetic core 3,30 surface of magnetic core Equipped with dissipating cover shell 2, the dissipating cover shell 2 and shell 1 are movably fastened, there are two the shell 1 is wherein set on the shell 1 of one end Above block tin 4, block tin 4 is by welding machine welding on 1 surface of shell, these block tins 4 are arranged in straight line, and each block tin 4 is all Level is inserted with a draw pin 5, and the end of the draw pin 5 facing away from magnetic core 3.

The dissipating cover shell 2 is made of outer cover 21 and inner cover 22, the outer cover 21 and inner cover 22 be movably fastened into one it is complete Whole structure, the outer cover 21 is identical with the size of inner cover 22, and outer profile is similar, easier for installation after superposition, the inner cover 22 Distance apart from magnetic core 3 is closer than outer cover 21.

The outer cover 21 and inner cover 22 are all equipped with more than two thermovent a, these thermovents a is in outer cover 21 and inner cover 22 The thermovent a of equidistant design, the outer cover 21 and inner cover 22 is straggly separated, while heat dissipation, the design of bilayer heat dissipation, if There is dust to enter in dissipating cover shell 2, do not have object and enter to 3 position of magnetic core, avoids magnetic core that short circuit phenomenon occurs.

Plate body 7, support column 10, parting bead 9 are additionally provided on the inner cover 22, the plate body 7 is equipped with more than two heat dissipations Mouth a, these thermovents a line up two column or more, and thermovent a parting bead 9 separates between two column, on four corners of the plate body 7 It connects vertical be equipped with and supports column 10, the support column 10 and plate body 7 are mold integral structure, and the support column 10 and outer cover 21 are living Dynamic engaging, the thermovent a separated are moved around after the foreign matter of outside or being such as ant can be allowed to enter, and magnetic core 3 is caused to radiate Effect is obstructed.

The parting bead 9 is inverted V-structure, and relative rectilinear structure is installed more stable and will not cover thermovent, no Influence heat dissipation effect.

The height of the support column 10 is slightly above the height of parting bead 9, that is, hollow between outer cover 21, inner cover 22 is set Meter, on the one hand, the outer cover 21 from four corner supports guarantees the problem of support force equilibrium, on the other hand, existing therebetween Difference in height makes way for the air between outer cover 21 and inner cover 22 and is able to carry out circulation, improves the flow rate of gas, dissipates to improve Thermal effect.

Plate body 7 another side opposite with support column 10 is equipped with insulating layer 8, and the insulating layer uses insulating materials such as polychlorostyrene Film made of ethylene synthase material etc., the insulating layer 8 are connected with plate body 7 by glue injecting glue, and insulating layer 8 separates magnetic core 3 The electric current generated during the work time plays the role of bucking current and leaps up stream.

When magnetic core 3 because can be radiated by thermovent a straggly on outer cover 21, inner cover 22 when work generates temperature, Outer cover 21, inner cover 22 tightly push down magnetic core 3, will not allow the outer bullet of magnetic core 3, guarantee the stability of variable-pressure operation, in this process If entering if there is objects such as dusts, firstly because the design straggly of thermovent a, will not allow dust to penetrate the heat dissipation of inner cover 22 Mouth a, can only rest on the upper surface of outer cover 21, cannot be introduced into 3 position of magnetic core, if there is the objects such as foreign matter or being such as ant It is separated into the parting bead 9 that also can be set as being inverted V-structure between outer cover 21, inner cover 22, avoids it from entering in magnetic core 3, make Magnetic core 3 is separated in the course of work when magnetic core 3 is worked at the insulating layer 8 of large area short circuit, while bottom setting The electric current of middle generation plays the role of bucking current and leaps up stream.

Problems solved by the invention be therefore in use magnetic core be easy to because chronically using and cause temperature Increase, heat dissipation is not easy, insulating tape theres is a phenomenon where degumming in the case where be easy for that magnetic core is caused to play outside, do not have the work of transformation With being in addition exactly that miniature transformer is commonly used in power device used in everyday, be easy to generate gap because beating, dust etc. is miscellaneous Object be easy to cause the phenomenon that can not radiating from the magnetic core that gap enters power device, the present invention pass through above-mentioned component mutual group It closes, the present invention double layer design hollow by outer cover 21, inner cover 22, on the one hand thermovent a straggly disperses caused by magnetic core On the other hand heat cooperates with parting bead 9, move around after preventing the foreign matter of outside or being such as ant from entering, magnetic core 3 is caused to dissipate Thermal effect is obstructed, and opposite to be wound using insulating tape, this radiating mode is stronger, and is capable of fixing folded magnetic core 3, It will not dissipate outside, can also separate the electric current that magnetic core 3 generates during the work time.

The basic principles, main features and advantages of the present invention have been shown and described above, the technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention can not only be realized in other specific forms under the premise of not departing from spirit of that invention or essential characteristic The present invention will also have various changes and improvements, these changes and improvements both fall within scope of the claimed invention, therefore this hair Bright claimed range is defined by appended claims and its equivalent, rather than above description limits.
