To achieve these goals, the utility model provides a kind of power supply changeover device with solid insulator, comprising:
One housing has a cavity volume;
One electronic building brick is placed in this cavity volume, and and the inwall of this housing between leave one wait to fill a vacancy between; And
Obturator with solid insulator, be filled in this wait to fill a vacancy between in.
The above-mentioned power supply changeover device with solid insulator, wherein, this electronic building brick comprises a circuit board and electrically connects a plurality of electronic building bricks of this circuit board.
Above-mentioned power supply changeover device with solid insulator, wherein, this obturator include with reperfusion mode be filled in this wait to fill a vacancy between in colloid.
The above-mentioned power supply changeover device with solid insulator, wherein, this colloid is an AB glue.
The above-mentioned power supply changeover device with solid insulator, wherein, this solid insulator is: Merlon (PC), anti-grand (Nylon), bakelite (Bakelite), fire prevention carbolic acid (FR Phenol) or fire proofing firbre (FRFiber).
The above-mentioned power supply changeover device with solid insulator, wherein, this solid insulator is to have the material that meets UL 94 standards or be the fireproofing flame-resistant material.
The above-mentioned power supply changeover device with solid insulator, wherein, this solid insulator is the colloid of non-curing.
Above-mentioned power supply changeover device with solid insulator, wherein, this solid insulator be shaped as circle, triangle, square, rectangle, polygon or irregularly shaped.
The above-mentioned power supply changeover device with solid insulator, wherein, this solid insulator is of a size of and this big or small suitable between waiting to fill a vacancy.
The above-mentioned power supply changeover device with solid insulator, wherein, this power supply changeover device is AC-AC transducer, AC-DC converter, DC-AC converter or DC to DC converter.
Compared to prior art, power supply changeover device with solid insulator of the present utility model, because of lower Merlon of its solid insulator use cost (PC) or anti-grand formation such as (Nylon) material, again with pour into after colloid mixes wait to fill a vacancy between, reduce the use amount of colloid by this, and then reduce the encapsulating cost, and meet requirements such as waterproof and dustproof and heat conduction again; Moreover, when this solid insulator is to have the material that meets UL 94 standards, or during other fireproofing flame-resistant material, also can has fire prevention, waterproof, anti-electromagnetic interference, heat conduction or increase function such as insulation impedance; In addition, the visual user demand of the utility model and the obturator part is filled in the space more increases convenience of the present utility model and practicality.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.
