Abstract
The utility model discloses a chute type ultrathin transformer which comprises a skeleton. The skeleton comprises a secondary end, a primary end and a connection part for connecting the secondary end and the primary end; the primary end and the secondary end are respectively provided with a wire-in slot and a pin; and the wire-in slot in the secondary end is a chute. According to the utility model, by increasing the distance between the pin and a coil, the possibility of poor voltage resistance is reduced.
Description
Technical field
The utility model relates to a kind of transformer, is specifically related to a kind of oblique slot type ultra-thin transformer, is applied on the LED TV.
Background technology
At present, the LED product is more and more higher to the requirement of ultra-thin, miniaturization and safety.The miniature transformer problem of withstand voltage is obviously restricting the manufacturing of transformer.
The utility model content
The utility model purpose: for the problem and shortage that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of oblique slot type ultra-thin transformer, increases the distance of pin and connecting portion (being the line bag), has reduced withstand voltage bad generation.
Technical scheme: for realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is a kind of oblique slot type ultra-thin transformer, comprise skeleton, described skeleton comprises that secondary end, primary side and connection be connected the connecting portion of secondary end and primary side, described primary side and secondary end are respectively equipped with leading groove and pin, and the leading groove that is positioned at described secondary end is skewed slot.
Preferably, the angle of described skewed slot and horizontal direction is 45 degree.
Preferably, the leading groove that is positioned at described secondary end is provided with step on line inlet port.Preferred, the height of described step is 0.3mm.
Preferably, the thickness that is provided with the zone of pin in described skeleton is 2.5mm.
Beneficial effect: the utility model changes the secondary end leading groove into oblique slot type, increases the distance of pin and line bag, has reduced withstand voltage bad generation; Increase step at the line inlet port that is wound around enamelled wire, make the liftoff certain height in enamelled wire lower end that is wound around on pin, be convenient to the parcel of scolding tin, effectively reduce the scolding tin time, prevent that the long rear line bag insulation of scolding tin time is impaired.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
as shown in Figure 1, oblique slot type ultra-thin transformer of the present utility model comprises skeleton 3, described skeleton comprises secondary end 1, primary side 2 and the connecting portion that is connected described secondary end and primary side (being the line bag) 4, this connecting portion 4 is insulators, described primary side 2 and secondary end 1 are respectively equipped with leading groove 6 and pin 7, the pin number that wherein is positioned at primary side and secondary end is 5, the leading groove that is positioned at primary side has 4, and be straight trough, and the leading groove quantity that is positioned at secondary end is 2, and the angle that is with horizontal direction is the skewed slots of 45 degree, increased the length of leading groove, thereby increased the coiling distance of secondary end pin and line bag, reduced withstand voltage bad generation.The leading groove that is positioned at secondary end is provided with on line inlet port and highly is the step 5 of 0.3mm, and the air line distance in pin and the skeleton outside that is formed into wire casing only is 0.5-0.6mm, therefore when the enamelled wire on pin enters line inlet port, leave the space between enamelled wire on the pin and the upper surface of pin skeleton of living in, can effectively reduce the scolding tin time, after preventing scolding tin time length, the insulating properties of line bag is impaired.Simultaneously, the skeleton thickness of pin present position is increased to 2.5mm by original 2mm, prevents after the assembling of pin and magnetic core withstand voltage bad.
