Abstract
The utility model provides a kind of electronic transformer skeleton, comprises the spiral portion with mesopore, and extended along two ends, spiral portion have primary terminals platform and secondary terminal board, is fitted with the many metal terminals for electrical connection bottom each terminal board respectively; Secondary terminal board metal terminal offers breach between any two, is used for placing the lead-out terminal of power module or other miniature devices.This electronic transformer skeleton compact, simplifies the manufacturing process of transformer, and can ensure safe enough distance, be conducive to automated production.
Description
Technical field
The utility model relates to a kind of electronic transformer skeleton, particularly 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 is in order to ensure enough safe distances, require simplified processing process simultaneously, remove the winding mode adding barricade, Teflon sleeve pipe, so that automated production, the size of frame design can become large relatively, be unfavorable for that product is miniaturized, therefore making full use of of transformer framework space becomes particularly important.
Summary of the invention
The purpose of this utility model can make full use of spatial transformer further, realize the transformer framework of modular power source miniaturization under being to provide a kind of prerequisite ensureing safe enough distance.
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;
Dividing plate and skewed slot is provided with between described secondary terminal board and spiral portion;
The height and position of described lead-in wire skewed slot and junction, spiral portion is line bag height safety distance prompt line;
Described secondary terminal board top wherein side is provided with a groove;
Described secondary terminal board secondary metal terminal offers breach between any two;
Described notch geometry can be the combined shaped of arc, square, circular or three.
Due to the utilization of technique scheme, the beneficial effects of the utility model are: transformer can not utilize the insulating material such as barricade, sleeve pipe and easily meet safety distance, secondary metal terminal offers arc notch between any two simultaneously, neither affect safety distance between primary coil and secondary PIN, this breach can be utilized to place lead-out terminal or other miniature devices of power module simultaneously, save space, furthermore achieved that miniaturization.

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 and Figure 2, 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.Be provided with the many metal terminals 31 for electrical connection bottom secondary terminal board 3, secondary boss 32 is provided with skewed slot between any two; Skewed slot 33 is positioned near metal terminal 31 side with form one end, 45 ° of slopes, and one end is positioned at secondary terminal board 3 with spiral portion 1 and forms safety distance prompt line 35; The lead-in wire of secondary coil is drawn by skewed slot 33, is 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 skewed slot 33 is formed is altitude line marks of line bag restriction, as long as that is the line bag height of entirety is no more than the position of indication wire 35, just can meet rigid safety required distance very well.In the top of secondary terminal board 3, wherein secondary metal terminal 31 is provided with a rectangular groove 36 from the side close to side.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 31.Secondary metal terminal 31 is provided with arc notch 37 between any two, and this breach does not affect the safety distance between primary coil and secondary PIN, but can utilize lead-out terminal or other miniature devices of breach 37 position placement module power supply, saves certain space.
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.Boss 32, 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, preferably adopting 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 skewed slot 33 and groove 36, do not need extra barricade and sleeve pipe, can ensure that primary arrives time inter-stage, magnetic core to the creepage distance of secondary inter-stage yet.Utilize position mounting terminal or other miniature devices of breach 37, space is fully used, and furthermore achieved that miniaturization.
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.
