Description
Technical field
The utility model relates to a kind of electronic transformer skeleton, particularly relates to a kind of electronic transformer skeleton applied 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---and transformer also must ensure certain safety distance while accomplishing miniaturization.In the various safety standard such as IEC, UL, CE, in safe distance (electric clearance and creepage distance), have detailed hard and fast rule to the high-frequency electronic transformer as electrical isolation device.
Existing transformer, for meeting safety requirement, adopts the winding mode adding barricade, Teflon sleeve pipe usually, or adopts the mounting structure of primary side fly line.But transformer cost certainly will be caused like this to increase, and processing technology is complicated, is unfavorable for automated production.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic transformer skeleton, and this skeleton compact, simplifies the manufacturing process of transformer, and can ensure safe enough distance, is conducive to automated production.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of electronic transformer skeleton, comprise the spiral portion with mesopore, extended along two ends, spiral portion have primary terminals platform and secondary terminal board; The many metal terminals for electrical connection are fitted with respectively bottom each terminal board; Secondary terminal board lengthens and extends; Be provided with T-shaped baffle plate bottom secondary terminal board, T-shaped baffle plate is between spiral portion and metal terminal;
Dividing plate is provided with between described secondary terminal board and spiral portion;
The height and position of described dividing plate and junction, spiral portion is line bag height safety distance prompt line;
Side, described secondary terminal board top is provided with a groove;
Described secondary terminal board end is provided with breach, parallel with terminal;
Due to the utilization of technique scheme, the beneficial effects of the utility model are: the groove of the T-shaped baffle plate set up between spiral portion and secondary metal terminal and side, secondary terminal board top can strengthen primary coil and secondary PIN, safety distance between magnetic core and secondary PIN, like this can the insulating material such as economization barricade, sleeve pipe, secondary winding is without the need to fly line, greatly simplify transformer winding technique, save man-hour, realize automated production; The breach that secondary terminal board side parallel with terminal is arranged may be used for placing Miniature component or terminal, effectively utilizes space, more contributes to the Miniaturization Design of modular power source.
Accompanying drawing explanation
Fig. 1 is electronic transformer skeleton elevated bottom perspective schematic diagram described in the utility model;
Fig. 2 is coil lead cabling schematic diagram of the present utility model;
Fig. 3 is electronic transformer skeleton top perspective schematic diagram described in the utility model;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
A kind of electronic transformer skeleton, as shown in Figure 1, Figure 2, Figure 3 shows, the preferred horizontally-mounted flat structure of the utility model main embodiment, the spiral portion 1 of skeleton is provided with the mesopore 2 for magnetic core assembling, extends to secondary terminal board 3 and primary terminals platform 4 by spiral portion 1 to two ends.Secondary terminal board 3 opposing primary terminal board 4 lengthens and extends, and soly effectively can increase electric clearance; Be provided with the many metal terminals 31 for electrical connection bottom secondary terminal board 3, secondary terminal board 3 is provided with dividing plate 32 with junction, spiral portion 1, is provided with T-shaped baffle plate 33 between metal terminal 31 and dividing plate 32; "-" portion of T-shaped baffle plate 33 is parallel with metal terminal 31, and " | " portion of T-shaped baffle plate 33 extends perpendicular to metal terminal 31; Opened a wire casing 34 in the middle of dividing plate 32, the lead-in wire of secondary coil is drawn by wire casing 34, and the two ends walking around "-" portion of T-shaped dividing plate 33 are wound into above metal terminal 31, effectively can increase the creepage distance of lead-in wire like this.The safety distance prompt line 35 that wire casing 34 is formed is altitude line marks of line bag restriction, as long as the line bag height of entirety is no more than the position of indication wire 35 in other words, just can meet rigid safety required distance very well.The side, top of secondary terminal board 3 is provided with a rectangular groove 36.As shown in Figure 3, after magnetic core installed by transformer, this groove 36 effectively can increase the creepage distance of magnetic core and primary side metal terminal 33.Secondary terminal board 3 opposite side place parallel with terminal 31 has square breach 37, as design electronic products PCB, at these square breach 37 accommodating terminal or suitable components and parts, effectively can utilize space, contribute to the Miniaturization Design of modular power source.
Be provided with many bottom primary terminals platform 4 equally and arrange multiple boss 42 between metal terminal 41 and spiral portion for the metal terminal 41 of electrical connection, boss 42 between any two reserved coil lead goes out groove 43.Dividing plate 32, T-shaped baffle plate 33, boss 42 are coplanar relative to skeleton bottom level, and the level being so more conducive to transformer is installed.
As the utility model, adopt the electronic transformer that this skeleton is made, preferred to adopt elementary be enamelled wire, and secondary be that the winding of three layer insulation wire forms structure, and is regarded by magnetic core and elementaryly carry out corresponding safety protection Design.Because skeleton is itself by the structural relation of secondary terminal board 3, dividing plate 32, T-shaped baffle plate 33 and groove 36, do not need extra barricade and sleeve pipe, can ensure that primary arrives time inter-stage, magnetic core to the safety distance of secondary inter-stage yet.Meanwhile, the setting of square breach 37, more effectively can utilize space, contributes to the Miniaturization Design of modular power source.
Execution mode of the present utility model is not limited thereto; according to foregoing of the present utility model; utilize the ordinary technical knowledge of this area and effective means; do not departing under the above-mentioned basic thought prerequisite of the utility model; the utility model can also make the amendment of other form, replacement or change, all drops within the utility model rights protection scope.
