Contact even squeezes other electronic devices of surrounding, brings severe compromise, such transformer peace to whole electronic product
Can not repair after dress can only scrap, and therefore, the magnetic core deflection of cylinder core transformers belongs to serious functional defect, it would be highly desirable to solve
Certainly.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of magnetic core anti-deflection transformer, in cylinder core transformer
In the case that device overall structure is constant, insulation spacer is positioned using transformer framework pin, it is recessed by the circular arc of insulation spacer
Slot limits the stitch of connection magnetic core steel clamp, prevents magnetic core from deflecting with skeleton, which has structure simply convenient for production,
Use reliable, economical and practical advantage.
The technical solution adopted by the present invention to solve the technical problems is: a kind of magnetic core anti-deflection transformer, including skeleton
And magnetic core, which is characterized in that skeleton is made of the round wire-blocking board at bobbin and both ends, and the wire-blocking board of skeleton one end is with symmetrical
Pin seat, be fixed with pin on pin seat, be cylindrical body, magnetic core both ends baffle inner surface circular arc and middle part circle in the middle part of magnetic core
The cylinder center of circle is identical, and magnetic core side end has rectangular recess, there is circular hole and arc groove on insulation spacer, and there is card at steel clamp both ends
There is the stitch of stretching in one end of pawl, steel clamp, and the cylindrical body of magnetic core is fitted into the centre bore for being wound with coil rack wire-blocking board,
The claw of steel clamp is fastened in the rectangular recess of skeleton both ends magnetic core, by the circular hole of insulation spacer and arc groove and skeleton pin
Contraposition installation, meanwhile, the stitch of steel clamp is fastened in the arc groove of insulation spacer.
The present invention can be also achieved by the following measures: the circular hole and arc groove of insulation spacer and the Pin locations of skeleton
Identical, for insulation spacer with a thickness of 0.2mm ~ 1.0mm, the pin of skeleton is pin type pin, and the circular hole on insulation spacer is symmetrical
Cornerwise both sides are mutually perpendicular in insulation spacer quadrangle, pair of the arc groove processing on insulation spacer in insulation spacer quadrangle
On linea angulata.
The invention has the advantages that utilizing transformer bone in the case where cylinder core transformers overall structure is constant
Frame pin positions insulation spacer, is limited by the arc groove of insulation spacer to the stitch of connection magnetic core steel clamp, it is ensured that magnetic core
It will not deflect between skeleton, thoroughly eliminate the security risk of cylinder core transformers.

Specific embodiment
The present invention includes skeleton 1 and magnetic core 2, and skeleton 1 is made of the round wire-blocking board 6 at bobbin 14 and both ends, skeleton 1 one
The wire-blocking board 6 at end has symmetrical pin seat, is fixed with pin 5 on pin seat, is cylindrical body 7,2 both ends of magnetic core in the middle part of magnetic core 2
8 inner surface circular arc of baffle is identical as 7 center of circle of middle part cylindrical body, and 2 side end of magnetic core has rectangular recess 9, has circle on insulation spacer 4
There is claw 12 at hole 10 and arc groove 11,3 both ends of steel clamp, and there is the stitch 14 of stretching in one end of steel clamp 3, by the cylindrical body 7 of magnetic core 2
It is fitted into the centre bore for being wound with 1 wire-blocking board 6 of coil rack, the claw 12 of steel clamp 3 is fastened on the square of 1 both ends magnetic core 2 of skeleton
In connected in star 9, the circular hole 10 of insulation spacer 4 and the contraposition of arc groove 12 and 1 pin 5 of skeleton are installed, meanwhile, by steel clamp 3
Stitch 13 is fastened in the arc groove 12 of insulation spacer 4, the circular hole 10 and arc groove 11 and 1 pin of skeleton of insulation spacer 4
5 positions are identical, and insulation spacer 4 is pin type pin with a thickness of 0.2mm ~ 1.0mm, the pin 5 of skeleton 1, the circular hole on insulation spacer
10, which are symmetrically distributed in 4 four jiaos of insulation spacer, is mutually perpendicular to cornerwise both sides, and the arc groove 12 on insulation spacer is processed exhausted
On the diagonal line that 4 four jiaos of edge gasket.
Cylinder core transformers on the market are that 2 cylindrical body 7 of magnetic core is packed into skeleton after 1 wound around coil of skeleton at present
In the centre bore of both ends wire-blocking board 6, the claw 12 of steel clamp 3 is stuck in the rectangular recess 9 of 1 both ends magnetic core 2 of skeleton, that is, use
2 steel clamps 3 connect a skeleton 1 and two magnetic cores 2 in the transformer for being combined into an entirety, due to matching for skeleton 1 and magnetic core 2
There are gaps for conjunction, and cylinder core transformers finished product is when the links such as packaging, transport, installation are by external force, the cylinder of magnetic core 2
Body 7 is easy to rotate in the centre bore of skeleton wire-blocking board 6, and magnetic core 4 is made to generate deflection, and the present invention passes through in cylinder core transformers
