Compared with the prior art, the transformer framework capable of meeting the safety requirements can reduce the size and is convenient to install.
Description
The technical field is as follows:
the utility model relates to a transformer skeleton field specifically says a transformer skeleton of adaptable ann's rule requirement.
Background art:
in order to adapt to a high-power transformer, the creepage distance from a magnetic core to a PIN needle of a transformer skeleton needs to be increased, in the prior art, the creepage distance is generally realized by increasing the height of a terminal block of the transformer skeleton, namely the height difference formed by the end face of the transformer skeleton and the terminal block realizes the high-power requirement, and the structure causes inconvenience to subsequent installation.
The utility model has the following contents:
the utility model aims to solve the technical problem that a transformer skeleton of adaptable ann's rule requirement is provided, this transformer skeleton compares prior art, easy to assemble.
The technical solution of the utility model is, a transformer skeleton of adaptable ann's rule requirement is provided, including the wrapping post of taking the centre bore, upper end plate and the lower terminal plate that forms are extended to the outside along wrapping post both ends ring, lower terminal plate both sides are equipped with left locating plate and right locating plate, the upper end plate both sides are equipped with primary terminal platform and secondary terminal platform, primary terminal platform and secondary terminal bench perpendicular surface insert and are equipped with the stitch terminal, secondary terminal platform width is greater than primary terminal platform width, the stitch terminal of secondary terminal platform is not less than 9.1mm apart from the distance of wrapping post, primary terminal platform is not less than 4.6mm apart from the distance of wrapping post, primary terminal platform and secondary terminal platform are equipped with the shielding plate with one side upper surface vertical that the wrapping post is connected, primary terminal platform and secondary terminal platform are kept away from wrapping post one side and are equipped with the card wire.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: on the basis of the prior art, the width of the secondary terminal block is prolonged, and the shielding plates are additionally arranged on the inner sides of the primary terminal block and the secondary terminal block, so that the high-power requirement can be realized on the premise of reducing the size as much as possible, and the effect of lengthening the creepage and improving the safety is achieved.
Preferably, the height of the shield plate is 3 to 5 mm.
Description of the drawings:
fig. 1 is a side view of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1-3, a transformer framework adaptable to the safety requirements comprises a winding post 1 with a central hole, an upper end plate 2 and a lower end plate 3 extending outwards from the two ends of the winding post 1, a left positioning plate 31 and a right positioning plate 32 arranged on the two sides of the lower end plate 3, a primary terminal block 4 and a secondary terminal block 5 arranged on the two sides of the upper end plate 2, pin terminals vertically inserted on the upper surfaces of the primary terminal block 4 and the secondary terminal block 5, the width of the secondary terminal block 5 is larger than that of the primary terminal block 4, the distance between the pin terminals of the secondary terminal block 5 and the winding post is not less than 9.1mm, the distance between the primary terminal block 4 and the winding post is not less than 4.6mm, a shielding plate 6 is vertically arranged on the upper surface of one side of the primary terminal block 4 and the secondary terminal block 5 connected with the winding post 1, the shielding plate 6 is integrally formed with the winding post, the upper end plate, and the primary terminal block 4 and the secondary terminal block 5 are provided with wire clamping grooves at one sides far away from the winding posts. The width of the secondary terminal block is increased to be not less than 9.1mm, the shielding plates are additionally arranged on the inner sides of the primary terminal block and the secondary terminal block, the height of each shielding plate is 3-5mm, the safety regulation of the high-power transformer on the creepage distance from the magnetic core to the PIN needle of the transformer framework can be met, the creepage lengthening effect is achieved, the size of the transformer framework is reduced as far as possible, and the follow-up installation and use are facilitated.
On the basis of the prior art, the width of the secondary terminal block is prolonged, and the shielding plates are additionally arranged on the inner sides of the primary terminal block and the secondary terminal block, so that the high-power requirement can be realized on the premise of reducing the size as much as possible, and the effect of lengthening the creepage and improving the safety is achieved.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
