Description
Technical field
It the utility model is related to the transformation of the pin configuration improved technology, especially ting model high voltage of device for transformer
Device.
Background technology
The requirement of power transformer product safety passes through the possible application method of pseudo-terminal client, and product is needed by a series of
Test, examination product be likely to occur in the case of normal or non-normal use electric shock, fire, mechanical wounding, heat injury, change
Injury, radiation injury, food hygiene etc. harm are learned, by designing accordingly before product export, is prevented.
Transformer and its component parts, including skeleton, insulating tape, polyester insulated adhesive tape etc., all needing to meet safety will
Ask.It is more to be directed to content, including, space length (clearance)/electric clearance is between two conductive parts
Or the most short space length measured between conductive parts and equipment protection interface；Or creepage distance (Creepage)/climb electricity away from
From；Or the shortest path between two conductive parts measured along insulating surface or between conductive parts and equipment protection interface
Footpath.Such as, it is desirable to when winding uses enameled wire, the barricade with 3mm is just had on BOBBIN both sides.
For ting model power transformer product, the coil winding order on coil holder is followed successively by, first coiling primary coil, then
Again in its peripheral coiling secondary coil.Since coil holder model is smaller, under usual structure the scolding tin end of primary side PIN foot to primary
Coil 6 apart from hypotelorism, inadequate safe distance, can not meet the requirement of safety, and also limit ting model change at the same time
The high voltage performance of depressor product.
Utility model content
The purpose of this utility model is to provide the transformer of ting model high voltage, solves above technical problem.
The purpose of this utility model will be realized by following technical measures：Including coil holder, primary side PIN foot, primary side
PIN foot, primary side lead, primary coil, secondary coil and primary side scolding tin end；Coil holder upper surface opposite sides is fixed first respectively
Level side PIN foot and primary side PIN foot, coiling primary coil on coil holder inside middle portion, the coiling secondary coil on the outside of primary coil,
By primary coil connecting lead wire to primary side PIN foot, by secondary coil connection primary side lead to coil holder outside but not with primary side
PIN foot, the fixed secondary side scolding tin end on primary side lead outer end, the primary side scolding tin end are drawn apart from primary coil and primary side
The distance of 5 connecting pin of line is more than 1.5 times of primary side PIN foot to primary coil with the distance of primary side lead connecting pin.
Especially, iron core is installed on coil holder.
Especially, the primary coil coiling number of turn is the 1/2 of the 7 coiling number of turn of secondary coil.
Especially, the shielded layer do not closed is set between primary coil and secondary coil.
Especially, distance of the primary side scolding tin end apart from primary coil Yu primary side lead connecting pin is more than primary side PIN
Foot is to 2.5 times of primary coil and the distance of primary side lead connecting pin but less than 3.5 times.
The advantages of the utility model and effect：By resetting the scolding tin end structure fixed form of primary side lead, add
Big primary side PIN foot arrives scolding tin end distance, and structure simplicity is easy to implement, is obviously improved ting model transformer high-voltage resistance capability
With safety standard.
Brief description of the drawings
Fig. 1 cuts open for 1 front view structure of the utility model embodiment shows schematic diagram.
Fig. 2 is 1 overlooking the structure diagram of the utility model embodiment.
Reference numeral includes：
Coil holder 1, iron core 2, primary side PIN foot 3, primary side PIN foot 4, primary side lead 5, primary coil 6, secondary coil

Embodiment
The utility model includes：Coil holder 1, primary side PIN foot 3, primary side PIN foot 4, primary side lead 5, primary coil 6,
Secondary coil 7 and primary side scolding tin end 8.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：As shown in Figure 1,1 upper surface opposite sides of coil holder fixes primary side PIN foot 3 and primary side respectively
PIN foot 4, coiling primary coil 6 on 1 inside middle portion of coil holder, in 6 outside coiling secondary coil 7 of primary coil, by primary coil 6
Connecting lead wire to primary side PIN foot 3, by secondary coil 7 connect primary side lead 5 it is outer to coil holder 1 but not with primary side PIN foot 4,
The fixed secondary side scolding tin end 8 on 5 outer end of primary side lead, the primary side scolding tin end 8 is apart from primary coil 6 and primary side lead
The distance of 5 connecting pins is more than 1.5 times of primary side PIN foot 4 to primary coil 6 with the distance of 5 connecting pin of primary side lead.
In foregoing, iron core 2 is installed on coil holder 1.
In foregoing, the 6 coiling number of turn of primary coil is the 1/2 of the 7 coiling number of turn of secondary coil.
The shielded layer do not closed is set in foregoing, between primary coil 6 and secondary coil 7.
In foregoing, distance of the primary side scolding tin end 8 apart from primary coil 6 Yu 5 connecting pin of primary side lead is more than primary side
