Abstract
The utility model discloses a neon lamp transformer packaged with a ceramic body, relating to a transformer. The utility model is a transformer formed by that a dual chamber ceramic body is used as a bracket to separately pack a circuit board and a high-voltage and a low-voltage coils as well as a rectifier and a high frequency magnetic core in a circuit board package cavity and a high-voltage package cavity. A favorable insulating effect can be produced, and the utility model has a good heat radiation characteristic to high-voltage package electronic components; the utility model can be used as various decorative neon lamp transformers.
Description
The utility model discloses a kind of gas tube sign transformer, relate to transformer with the ceramic body encapsulation.
The current full embedding electric neon light transformer that uses is to adopt high-tension coil and the rectifying device high voltage package of encapsulation separately, adds the high frequency magnetic core and the low pressure winding adds circuit board again, makes antivacuum secondary with ordinary epoxy resin and encapsulates and form.Impurity such as high voltage package ambient air, water vapour can't clear during its secondary encapsulation of this transformer one side, cause high voltage package short useful life, the failure rate height; Need use a large amount of epoxy resin when the aspect secondary encapsulates in addition, cause the production cost height.
The purpose of this utility model provides a kind ofly to be made support with the two-chamber ceramic body and is installed in circuit board and high voltage package accessory in the ceramic body and casing insulation, and electronic component can dispel the heat, the gas tube sign transformer of long service life.
The utlity model has ceramic body and support thereof, it adopts ceramic cavity C to make to separate support, be separated into cavity, circuit board 2 with by high-tension coil 4, low-voltage coil 5, the high voltage package that high frequency magnetic core 3 and rectifier 6 constitutes is separated and is packaged among circuit board package cavity B and the high voltage package package cavity A, makes it with casing insulation and make high voltage package electronic component generation better heat radiating effect.In the production process, high-tension coil 4 and low-voltage coil 5, high frequency magnetic core 3, rectifier 6 respectively place in the high voltage package package cavity A, do the integrated encapsulation of vacuum, can prevent that impurity such as air, water vapour from entering and influence useful life of high voltage package.Adopt the integrated magnetic core of circumference that high-tension coil 4 and low-voltage coil 5 are put in up and down in the ceramic body, reduced the space, reduced volume.High voltage package and circuit board can be separated embedding at least in two cavitys.
The utility model takes the two-chamber ceramic body to make support, makes in circuit board and the high voltage package installation process with casing insulation and can produce better heat radiating effect; High-voltage coil and low-voltage coil in the production process, magnetic core and rectifier cell are placed on the A chamber simultaneously and do integrated encapsulation, can prevent that impurity such as air and water vapour from entering and influence useful life; Adopt ceramic body, made the secondary encapsulation save epoxy resin, reduced production cost; Employing side, the integrated magnetic core of circle are sidelong high-voltage coil and low-voltage coil up and down, have reduced the space; Separate encapsulation because of high voltage package and circuit board with two chambeies, reduced of the influence of high voltage package high-frequency electric field, can prolong transformer's life span electronic device.
Now be illustrated in conjunction with the accompanying drawings
Fig. 1 is the utility model side plan view
Fig. 2 is the ceramic cavity plan view from above
Among the figure, A-high voltage package package cavity, B-circuit board package cavity, C-ceramic cavity, the input of 1-power supply, 2-circuit board, 3-high frequency magnetic core, 4-high-tension coil, 5-low-voltage coil, 6-rectifier, 7-high pressure output lead.
In figure, circuit board 2 is loaded among the circuit board package cavity B, with high frequency magnetic core 3, high-tension coil 4, low-voltage coil 5, rectifier 6 are connected and installed in the high voltage package package cavity A.From input termination power input 1, output is set up high pressure output lead 7, is connected in the 220V voltage then can use.
Claims (2)
1, a kind of gas tube sign transformer with the ceramic body encapsulation, have ceramic body and support thereof, it is characterized in that, ceramic cavity C makes to separate support, be separated into cavity, circuit board 2 with by high-tension coil 4, low-voltage coil 5, the high voltage package separation that high frequency magnetic core 3 and rectifier 6 constitute is packaged among high-tension circuit plate package cavity B and the high voltage package package cavity A.
2, according to the described gas tube sign transformer of claim 1, it is characterized in that have an area of integrated magnetic core, high-tension coil 4 and low-voltage coil 5 are put in the ceramic body up and down with the ceramic body encapsulation.
