Description
Technical field
The utility model belongs to technical field of transformer manufacturing, specifically a kind of security isolation transformation with sheath body
Device.
Background technique
Now, with the development of science and technology, the type of electronic product is more and more, as people are to electronic product safety
The raising of performance requirement, power transformer are updated in continuous upgrading, and reliable and stable work and use for a long time are that everybody pursues
Target, at this stage, traditional transformer volume used in household appliances power supply is big, and operating temperature is high, only does letter between internal winding
Single adhesive tape isolating and protecting processing, internal heat dissipating condition is poor when transformer works, and temperature is high, accelerates material aging, reduces
The service life of transformer brings hidden danger to the trouble free service of entire electrical equipment, in order to promote the reliability of traditional transformer,
Using the method for increasing insulating tape between winding, the requirement of electronic product continuous trouble free service for a long time is had been unable to meet.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of safety isolating transformer with sheath body, it is logical
The change of transformer bobbin structure and the design of sheath body isolation two-stage coil are crossed, the transformer is made to have the advantage that structure
Simply, easy to make, safe and reliable, service life greatly improves.Used by the utility model solves its technical problem
Technical solution is: a kind of safety isolating transformer with sheath body, including skeleton, sheath body, which is characterized in that skeleton by bobbin and
The wire-blocking board at both ends forms, and interval support plate is distributed on bobbin, there are the positioning pins of stretching, wire-blocking board in one end of wire-blocking board
Rectangular recess have the welding pin of stretching and the circular hole of connecting end surface, have line groove out on the partition of sheath body protrusion, sheath body is horizontal
To there is disconnection mouth, it is wound with primary coil in the winding slot that skeleton both ends wire-blocking board and interval support plate are formed on bobbin,
Sheath body is sleeved in the interval support plate between skeleton wire-blocking board, is wound with secondary coil between the partition of sheath body.
The utility model can be also achieved by the following measures: interval support plate is evenly distributed on bobbin and height phase
Together, height of the winding height of primary coil lower than interval support plate.
The utility model has the beneficial effects that being dielectrically separated from design by annular sheath body, traditional transformation is revolutionized
The method of two-stage coil is isolated with insulating tape for device, and the interval support plate of skeleton bobbin can play a supporting role to sheath body,
Make the coiling of primary coil orderly regular again, the lateral of annular sheath body disconnects mouth, is simple and efficient transformer assembling, it is raised every
Plate keeps sheath body isolation effect more preferable, and high temperature insulation material improves the isolation Level of sheath body, is able to satisfy high safety grade isolation electricity
The requirement in source, the pin and threading circular hole of skeleton wire-blocking board rectangular recess, keeps external connection convenient and fast connection with welding pin, separately
Outside, solder joint avoids injury of the high temperature to coil and ontology far from transformer coil and ontology, make transformer security performance and
Service life is increased dramatically.

Specific embodiment
The utility model includes skeleton 1, sheath body 2, and skeleton 1 is made of bobbin 3 and the wire-blocking board at both ends 4, on bobbin 3
Interval support plate 5 is distributed with, one end of wire-blocking board 4 there are the positioning pins 14 of stretching, and the rectangular recess 6 of wire-blocking board 4 has stretching
The circular hole 9 of welding pin 7 and connecting end surface has line groove 10 out on the partition 8 of the protrusion of sheath body 2, and sheath body 2 laterally has disconnection mouth
11, primary coil, sheath body 2 are wound in the winding slot that 1 both ends wire-blocking board 4 of skeleton is formed on bobbin 3 with interval support plate 5
It is sleeved in the interval support plate 5 between 1 wire-blocking board 4 of skeleton, secondary coil, interval support is wound between the partition 8 of sheath body 2
Plate 5 is evenly distributed on bobbin 3 and height is identical, and the winding height of primary coil is lower than the height for being spaced support plate 5.
Cross-line slot, the elastic heat insulating materials system of sheath body 2 are equipped with for the ease of the winding interval support plate 5 of primary coil
At, the bottom of sheath body 2 is not contacted with primary coil after assembling, increase two-stage coil isolation effect, thoroughly overcome tradition every
Thermo-labile from adhesive tape, easy to aging, the work defect of effect difference ensure that the normal work of transformer extends the use of transformer
Service life, partition 8 keep secondary coil winding simple and convenient with what 2 surface of sheath body was formed around line groove, and raised partition 8 makes two-stage line
Circle isolation safe is effective, and the lateral mouth 11 that disconnects of sheath body 2 keeps sheath body 1 easy to assembly efficiently, and the lead-out wire edge of primary coil keeps off line
4 inside of plate is welded with positioning pins 14, and external lead wire 15 goes out line groove 10 with by sheath body 2 by the end face circular hole 9 of wire-blocking board 4
The secondary coil lead-out wire of extraction is welded on together in the welding pin 7 of rectangular recess 6, avoids welding to transformer body and line
The high temperature injury of circle promotes the quality of transformer and security performance further.
