Abstract
The utility model is a converter for transforming the alternating power input into the alternating power output, in particular to a circuit and voltage frequency converter with the transformation into direct current in the midway. The utility model is a voltage frequency converter, which comprises a circuit board, a shell, and an electronic component. The structure of the converter is characterized in that the pins of the direct plug-in in the inverse (DC/AC) change circuit, the rectification circuit and the direct current regulator circuit bend for 90 degree and the direct plug-in paralleled with the circuit board is fixed below the circuit board fixed on the shell. The inboard of the shell is provided with an insulating gasket and on the surface a radiator flake is arranged. The advantage of the utility lies in that without changing the circuit structure, the converter can reduce the cost and volume and improve the heat emission efficiency by changing the structure of the pin in the direct plug-in, removing the original radiator flake and adding the radiator flake on the shell surface emitting heat through the shell.
Description
Technical field
The utility model belongs to the transducer that the AC power input is transformed to AC power output, especially belongs to have the circuit voltage frequency converter that intermediate conversion is a direct current.
Background technology
Existing voltage to frequency converter as shown in Figure 1, because the straight cutting spare caloric value in inverter circuit, rectification circuit, the direct current regulation circuit is big, therefore these vertically arranged straight cutting spare sides all need to be provided with fin, because the restriction of volume, fin is less, radiating effect is bad, and owing to the existence of fin, the volume of voltage to frequency converter is also bigger simultaneously.
Summary of the invention
The utility model purpose is to overcome above-mentioned shortcoming, provides that a kind of volume is little, the voltage to frequency converter of good heat dissipation effect.
The technical scheme that the utility model adopted is a kind of voltage to frequency converter, comprise circuit board, housing, electronic component, its structural feature is: bending pins 90 degree of the straight cutting spare in inverter circuit, rectification circuit, the direct current regulation circuit, straight cutting spare is parallel with circuit board, and be fixed in the below of circuit board, there is insulation cushion the housing inboard, and circuit board is fixed on the housing, is shaped on fin on the housing.
The utility model is by the bending pins 90 with straight cutting spare, make straight cutting spare become horizontal, reduced the height of electronic component, help reducing overall volume, by tightening up circuit board straight cutting spare is pressed on insulation cushion simultaneously, promptly be close to housing, directly dispel the heat by housing, need not other radiation fin, also increased area of dissipation, good heat dissipation effect.
Traditional electronic product all be with straight cutting spare vertical fixing on circuit board, the utility model has overcome the thinking inertia that this thinking set caused, creatively change the pin configuration of straight cutting spare, with its bending 90, and utilize fixing circuit board to fix and compress straight cutting spare, directly dispel the heat by housing, produced unexpected technique effect.Therefore, the utility model is a kind of innovation that overcomes technology prejudice.
The purpose of this utility model can also be realized better by following approach.
Inverter circuit, rectification circuit, direct current regulation circuit are arranged in respectively on three limits of circuit board, triangular spacing is far away as far as possible, because the straight cutting spare in these three circuit is heater element main in the voltage to frequency converter, and is arranged apart, helps improving radiating effect.
Advantage of the present utility model is and can by changing the structure of straight cutting spare pin, cancels original fin under the situation that does not change circuit design, increase fin at surface of shell, utilize housing to dispel the heat, reduce cost thereby reach, reduce volume, improve the purpose of radiating effect.
