Abstract

The utility model discloses an electronic transformer framework which comprises a line coiling part with a middle hole, wherein a primary terminal table and a secondary terminal table are arranged along the two ends of the line coiling part in an extending manner; a plurality of metal terminals for electrical connection are respectively inserted at the bottom part of each terminal table; a T-shaped baffle is arranged at the bottom of the secondary terminal table, and positioned between the line coiling part and the metal terminals; a baffle plate is arranged between the secondary terminal table and the line coiling part; a vertical part of the T-shaped baffle extends to the line coiling part to be in parallel with the baffle plate, and divides out two symmetrical equal beveled slots as coil extension lines on the baffle plate. The framework can enlarge the safety distance between a magnetic core and a primary coil and between the magnetic core and a secondary PIN foot, so that insulating materials such as baffle walls and sleeve pipes can be reduced; the winding technology of the transformer can be simplified; the working hour can be reduced; the automatic production can be realized.

Description

A kind of electronic transformer skeleton

Technical field

The utility model relates to a kind of electronic transformer parts, applies to specifically a kind of electronic transformer skeleton in modular power source.

Background technology

Along with the volume of modular power source reduces, power density is increasing, just requires its core power device transformer also must guarantee certain safety distance when accomplishing miniaturization.At IEC, UL in the various safety standards such as CE, is having detailed hard and fast rule to the high-frequency electronic transformer as the electrical isolation device aspect safe distance (electric clearance and creepage distance).

Existing transformer adopts for satisfying the safety requirement winding mode that adds barricade, Teflon sleeve pipe usually, perhaps adopts the mounting structure of primary side fly line.But certainly will cause like this transformer cost to increase, processing technology is complicated, is unfavorable for automated production.

Summary of the invention

It is small and exquisite that the purpose of this utility model is to provide a kind of volume, simplifies the transformer manufacturing process, and can guarantee the electronic transformer skeleton of safe enough distance.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of electronic transformer skeleton comprises the spiral section with mesopore, extends along spiral section two ends to be provided with elementary terminal board and secondary terminal board; Be fitted with respectively the metal terminal of the many electric connections of confession bottom each terminal board; Secondary terminal board bottom is provided with T-shaped baffle plate, and T-shaped baffle plate is between spiral section and metal terminal;

Be provided with dividing plate between described secondary terminal board and spiral section; It is concordant with dividing plate that the vertical part of described T-shaped baffle plate extends to spiral section, and be partitioned into two symmetry equivalent skewed slots as lead-out wires of coil on dividing plate.

The height and position of described lead-in wire skewed slot and spiral section junction is line bag height safety distance prompt line.

Both sides, described secondary terminal board top respectively are provided with a groove.

Due to the utilization of technique scheme, the beneficial effects of the utility model are: the groove of the T-shaped baffle plate of setting up between spiral section and secondary metal terminal and both sides, secondary terminal board top can strengthen the safety distance between magnetic core and primary coil, magnetic core and secondary PIN pin.Like this can the economization barricade, the insulating material such as sleeve pipe, simplify transformer winding technique, save man-hour, realize automated production.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

A kind of electronic transformer skeleton, as shown in Figure 1 and Figure 2, the preferred horizontally-mounted flat structure of the utility model main embodiment, the spiral section 1 of skeleton is provided with the mesopore 2 for the magnetic core assembling, and section 1 extends to secondary terminal board 3 and elementary terminal board 4 to two ends by spiral.Secondary terminal board 3 bottoms are provided with the metal terminal 31 of the many electric connections of confession, and secondary terminal board 3 is provided with dividing plate 32 with spiral section 1 junction, is provided with T-shaped baffle plate 33 between metal terminal 31 and dividing plate 32; The transverse part of T-shaped baffle plate 33 is parallel with metal terminal 33, and it is concordant with dividing plate 32 that the vertical part of T-shaped baffle plate 33 extends to spiral section 1, and be partitioned into two symmetry equivalent skewed slots 34 as lead-out wires of coil on dividing plate 32; Skewed slot 34 is positioned at T-shaped dividing plate transverse part two inboards with 45 ° of slope form one ends, and an end is positioned at dividing plate 32 with spiral section 1 and forms safety distance prompt line 35; The lead-in wire of secondary coil is drawn by skewed slot 34, and the two ends of walking around the transverse part of T-shaped dividing plate 33 are wound into above metal terminal 31, can effectively increase like this creepage distance of lead-in wire.The safety distance prompt line 35 that skewed slot 34 forms is altitude line signs of line bag restriction, as long as whole line bag height is no more than the position of indication wire 35, just can finely satisfy rigid safety required distance in other words.The top of secondary terminal board 32 respectively is provided with a rectangular groove 36 near the position, both sides.As shown in Figure 3, after transformer was installed magnetic core, this groove 36 can effectively increase the creepage distance of magnetic core and primary side metal terminal 33.

Elementary terminal board 4 bottoms are provided with the metal terminal 41 of the many electric connections of confession equally, between metal terminal 41 and spiral section, a plurality of boss 42 are set, and boss 42 is reserved between any two coil lead and gone out groove.Dividing plate 32, T-shaped baffle plate 33, boss 42 are coplanar with respect to the skeleton bottom level, and the level that so more is conducive to transformer is installed.

As the utility model, the electronic transformer that adopts this skeleton to make preferably adopts the elementary enamelled wire that is, secondary is the winding composition structure of three layer insulation wire, and magnetic core is regarded the elementary corresponding safety protection Design that carries out.Structural relation due to skeleton itself by dividing plate 32, T-shaped baffle plate 33 and groove 36 does not need extra barricade and sleeve pipe, can guarantee that primary arrives time inter-stage, magnetic core to the creepage distance of time inter-stage yet.

Execution mode of the present utility model is not limited to this; according to foregoing of the present utility model; utilize ordinary skill knowledge and the customary means of this area; do not breaking away under the above-mentioned basic fundamental thought of the utility model prerequisite; the utility model can also be made modification, replacement or the change of other various ways, within all dropping on the utility model rights protection scope.
