On secondary framework, the secondary framework is coated with shell, and the shell includes the side of bottom, rear portion and the left and right sides, institute
To state primary magnetic core and secondary magnetic core include bottom plate, is vertical at the lateral column of bottom plate both sides and in the middle part of the bottom plate and and lateral column
The center of the identical center pillar of protrusion direction, the primary skeleton is equipped with the hollow cavity being inserted into for primary magnetic core center pillar, the primary
Skeleton is equipped with primary pins holder by primary side bottom, and the primary pins holder is equipped with row's primary pins, described secondary
The center of grade skeleton is equipped with the hollow cavity being inserted into for secondary magnetic core center pillar, and the secondary framework is equipped with secondary by secondary end bottom
Pin holder, the secondary pins holder are equipped with row's secondary pins, and the side is equipped with the lateral column insertion for two magnetic cores
Side chamber.
Preferably, the primary skeleton is equipped at least two partition boards along the longitudinal direction, and primary skeleton and secondary framework exist
At least two grooves are formed between two neighboring partition board.
Preferably, the bottom of the shell, which is offered, enters conducive to dipping lacquer in dipping lacquer and is used for opening for heat dissipation when in use
Slot.
The technical solution adopted by the present invention, transformer framework are made of split type primary skeleton and secondary framework, secondary
Skeleton winds casing after secondary windings, by secondary cladding completely, secondary windings is isolated, can save magnetic core gum, save very
It when multiplexing and raw material, also allows for realizing automation coiling, and higher safety requirement can be better met between primary and secondary.
In addition, secondary framework is equipped at least two partition boards along the longitudinal direction, multiple grooves are formed in partition room, are increased
With primary creepage distance, and layer capacitance can be reduced, and can be to avoid the too big breakdown winding of voltage between layers, therefore made
Transformer in a limited space under it is safer, meet safety.
