Second magnetic core is increased along top surface to the creepage distance of secondary metal pin, the 4th limit plate of the second ontology and the 5th limit plate
Second magnetic core increases along two sides to the distance of secondary metal pin, the first limit plate and the second limit plate of the second ontology setting
Big second magnetic core along bottom surface to the distance of secondary metal pin, compare compared to the prior art install it is more convenient.
Preferably, opening up fluted at the top of second pedestal, the bottom of the 6th limit plate, which is provided with, to be connected in
The clamping portion of the groove.
Through the above technical solutions, connector is connected in the recessed of the second pedestal by the clamping portion of the 6th limit plate during installation
In slot, facilitates installation and make connector and the second pedestal that fastening is installed.
Preferably, first limit plate, the second limit plate, third limit plate, the 4th limit plate, the 5th limit plate and
6th limit plate is integrally formed.
The method of the present invention has the advantages that
1, the present invention adds connector and secondary metal pin is connected to connector, increase the second magnetic core edge and time
The creepage distance of grade metal pins, makes transformer framework meet the requirement of installation.
2, after the first noumenon of the invention is combined with the second ontology, the third limit plate of the second ontology increases the second magnetic core
Along top surface to the creepage distance of secondary metal pin, the 4th limit plate of the second ontology and the 5th limit plate increase the second magnetic core
Along two sides to the distance of secondary metal pin, the first limit plate and the second limit plate of the second ontology setting increase second
Magnetic core along bottom surface to the distance of secondary metal pin, compared to the prior art compared to install it is more convenient.
3, connector of the invention is connected in the groove of the second pedestal by the clamping portion of the 6th limit plate during installation, side
Just it installs and makes connector and the second pedestal to install to fasten.
