At present, in conventional PCBA, transformer is welded on to increase creepage distance on pcb board by fly line, and producting process difficulty is high, cause production efficiency and qualification rate low; Cause transformer height to uprise (at least 12mm) in addition, easily fall bad, charger overall dimension is increased, portability reduces.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mounting framework height reduction, not easily breaks, assembles easier charger.
In order to solve the problems of the technologies described above, the utility model provides a kind of charger preventing transformer from falling, comprise mounting framework, it is characterized in that, described mounting framework comprises the magnetic core groove of lateral direction penetrating, winding slot, be located at the elementary bottom bottom magnetic core groove two ends and secondary bottom respectively, multiple primary pins and secondary pins being connected to described elementary bottom and secondary bottom, described secondary bottom has the long muscles and bones extended laterally, described long muscles and bones bottom surface is provided with from the through metallic channel to end of root, wherein two secondary pins are connected to described long muscles and bones bottom end.
Further, described long muscles and bones both sides bottom edge and middle part are protruded to be provided with and are extended to insulation barricade close to end from root, and the insulation barricade at middle part forms described metallic channel respectively and between the insulation barricade at edge.
Further, described long muscles and bones is perpendicular to the length direction of secondary bottom.
Further, described elementary bottom and secondary bottom are parallel to magnetic core fluted shaft line.
Further, described elementary bottom and secondary bottom bottom surface are protruded to be provided with and are in conplane balance enclosure wall with described insulation barricade.
Further, the secondary pins on described secondary bottom layer length direction is greater than 6.5mm to the distance (L) of the secondary pins place straight line of long muscles and bones bottom end.
Further, it is highly 8.3mm.
Further, the length balancing enclosure wall protrusion is 1.3mm.
The mounting framework of the utility model charger arranges long muscles and bones at bottom, and muscles and bones end arranges pin, bottom surface arranges metallic channel long, magnetic core is made to cause this pin by metallic channel, the height of mounting framework also decreases, not easily fall bad, be conducive to reducing charger volume, portability is stronger.In addition, avoid fly line to weld on the one hand, produce, install more easily, reliability is strong, and efficiency is higher, extends creepage distance on the other hand, meets safety standard.

Fig. 5 is the stereogram of mounting framework of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described.
The utility model charger comprises mounting framework, as the front view of Fig. 1 ~ Figure 5 shows that mounting framework of the present embodiment, vertical view, right view, upward view and stereogram, comprise the magnetic core groove 1 of lateral direction penetrating, winding slot 2, be located at elementary bottom 31 bottom magnetic core groove 1 two ends and secondary bottom 32, multiple primary pins 41 and secondary pins 42,43 being connected to described elementary bottom 31 and secondary bottom 32 respectively, described elementary bottom 31 and secondary bottom 32 are parallel to magnetic core groove 1 axis.Described secondary bottom 32 one end has the long muscles and bones 50 extended laterally perpendicular to secondary bottom 32 length direction, described long muscles and bones 50 bottom surface is provided with from the through metallic channel 51,52 to end of root, wherein two secondary pins 42 are connected to described long muscles and bones 50 bottom end and are parallel to secondary bottom 32 length direction, all the other 3 secondary pins 43 are arranged along secondary bottom 32 length direction, and primary pins 41 is arranged along elementary bottom 31 length direction.As shown in Figure 4, for ensureing that creepage distance meets safety standard, the secondary pins 43 on described secondary bottom 32 length direction is greater than 6.5mm (the present embodiment is preferably 6.8mm) to the distance L of the secondary pins 42 place straight line of long muscles and bones 50 bottom end.Due to the existence of long muscles and bones 50, the height (height from balance enclosure wall 33 to top) of the utility model mounting framework reduces to 8.3mm.
Described long muscles and bones 50 both sides bottom edge and middle part are protruded to be provided with and are extended to insulation barricade 53,54,55 close to end from root, and the insulation barricade 54 at middle part respectively and form described metallic channel 51,52 between the insulation barricade 53,55 at edge.Described elementary bottom 31 and secondary bottom 32 bottom surface are all protruded to be provided with and are in conplane balance enclosure wall 33 with described insulation barricade 53,54,55, and the length that balance enclosure wall 33 protrudes from bottom bottom surface is 1.3mm.
The utility model arranges long muscles and bones at bottom, and muscles and bones end arranges pin, bottom surface arranges metallic channel long, magnetic core is made to cause this pin by metallic channel, fly line is avoided to weld on the one hand, produce, install more easily, reliability is strong, and efficiency is higher, extend creepage distance on the other hand, meet safety standard.In addition, highly also decrease, not easily fall bad, be conducive to reducing charger volume, portability is stronger.
