Abstract

A kind of miniature transformer skeleton is the utility model is related to, belongs to field transformer.Provided with skeleton, it is characterised in that be machined with single groove or multiple grooves on skeleton, left side groove and right side groove are machined with respectively on the outside of the PIN at left and right sides of skeleton.After the utility model is machined with a groove respectively on the outside of the PIN of skeleton both sides, each PIN hanging wire can individually enter groove, be not in the situation that two strands enter same groove, therefore be inherently eliminated two strands and enter line after same groove and contacted with each other the hidden danger of short circuit.

Description

Miniature transformer skeleton

Technical field

Field transformer is the utility model is related to, is a kind of miniature transformer skeleton in detail.

Background technology

It is well known that with the development of science and technology, semiconductor chip working frequency steps up in power supply industry, from 132KHz to 200KHz, then to 300KHz even 500KHz.The raising of working frequency of chip also promotes the volume of electronic transformer Increasingly develop to the direction of miniaturization.It is inevitable that framework material is carried out Miniaturization Design and life to adapt to the trend of miniaturization Production.For the transformer framework of miniaturization, when lead enters groove, it may appear that can not reasonable distribution due to slot number limited amount Situation.Such as there are four PINs skeleton side, there was only three grooves between four PINs.When four PINs all hanging wires of the side When situation about being needed in same skeleton grooves into two strands just necessarily occurs.Completely isolated insulation is necessary to ensure that between two strands again It is unable to contact short circuit.In this case, it is necessary to a wherein strand is worn into insulating sleeve and carries out isolated insulation.But increase is exhausted The measure of edge sleeve pipe can increase the task difficulty of transformer, or even be reduction of the production efficiency of product.Do not conform in casing length Under the extreme case of reason, the hidden danger of two strand contact short circuits can not still be completely eliminated.

The content of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of miniature transformer skeleton, is inherently eliminated Two strands enter line after same groove and contacted with each other the hidden danger of short circuit.

Technical scheme is used by the utility model solves its technical problem：A kind of miniature transformer skeleton, provided with bone Frame, it is characterised in that be machined with single groove or multiple grooves on skeleton, a left side is machined with respectively on the outside of the PIN at left and right sides of skeleton Side channel and right side groove.

The beneficial effects of the utility model are, after being machined with a groove respectively on the outside of the PIN of skeleton both sides, each PIN hanging wire can individually enter groove, be not in the situation that two strands enter same groove, therefore be inherently eliminated two strands Line enters line after same groove and contacted with each other the hidden danger of short circuit.Insulating sleeve is also just eliminated simultaneously, finally enhances transformer Reliability, the production efficiency of transformer is improved, reduce the product cost of transformer, ensure that the product quality of transformer. Prior is due to the raising of transformer insulated performance, ensure that the work that power supply can be steady in a long-term.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1, structural representation of the present utility model, and a kind of schematic diagram of embodiment.

1. left side groove in Fig. 1,2. skeletons, 3. right side grooves, 4. grooves, 5.PIN pin.

Embodiment

As shown in figure 1, the present embodiment is provided with skeleton 2, three grooves 4 and four PINs 5 are machined with skeleton 2, skeleton 2 is left The outside of PIN 5 of right both sides is machined with left side groove 1 and right side groove 3 respectively.The present embodiment is provided with a left side at the bottom margin of skeleton 2 Side channel 1 and right side groove 3, so that totally five grooves on skeleton 2.Four PINs 5 all hanging wire when, any four therein can be utilized Groove, each groove enters a strand in the case of this is two kinds, is not in the situation that same groove enters two strands, therefore fundamentally disappear Contacted with each other the hidden danger of short circuit except two strands enter line after same groove.

Can also be single groove 4 in the present embodiment middle skeleton 2, the outside of PIN 5 of the single left and right sides of groove 4 processes respectively There are left side groove 1 and right side groove 3.

Claims

1. a kind of miniature transformer skeleton, provided with skeleton, it is characterised in that single groove or multiple grooves, skeleton are machined with skeleton Left side groove and right side groove are machined with respectively on the outside of the PIN of the left and right sides.
