The portion cylindrical body center of circle is identical, and magnetic core side end has rectangular recess, there is circular hole and arc groove on insulation spacer, and steel clamp both ends have
There is the stitch of stretching in one end of claw, 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, the circular hole of insulation spacer and arc groove are drawn with skeleton
Foot contraposition installation, meanwhile, the stitch of steel clamp is fastened in the arc groove of insulation spacer.
The utility model can be also achieved by the following measures: the circular hole and arc groove of insulation spacer and the pin of skeleton
Position is identical, and 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
It is distributed in insulation spacer quadrangle and is mutually perpendicular to cornerwise both sides, the arc groove on insulation spacer is processed in insulation spacer quadrangle
Diagonal line on.
The utility model has the beneficial effects that utilizing transformation in the case where cylinder core transformers overall structure is constant
Device skeleton 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
It will not deflect between magnetic core and skeleton, thoroughly eliminate the security risk of cylinder core transformers.

Specific embodiment
The utility model 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, bone
The wire-blocking board 6 of 1 one end of frame has symmetrical pin seat, is fixed with pin 5 on pin seat, is cylindrical body 7, magnetic core 2 in the middle part of magnetic core 2
Two end-stopping plates, 8 inner surface circular arc is identical as 7 center of circle of middle part cylindrical body, and 2 side end of magnetic core has a rectangular recess 9, on insulation spacer 4
There are circular hole 10 and arc groove 11, there is claw 12 at 3 both ends of steel clamp, and there is the stitch 14 of stretching in one end of steel clamp 3, by the circle of magnetic core 2
Cylinder 7 is fitted into the centre bore for being wound with 1 wire-blocking board 6 of coil rack, and the claw 12 of steel clamp 3 is fastened on 1 both ends magnetic core 2 of skeleton
Rectangular recess 9 in, the circular hole 10 of insulation spacer 4 and arc groove 12 and the contraposition of 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 skeleton 1 of insulation spacer 4
5 position of pin is identical, and for insulation spacer 4 with a thickness of 0.2mm ~ 1.0mm, the pin 5 of skeleton 1 is pin type pin, on insulation spacer
Circular hole 10 is symmetrically distributed in 4 four jiaos of insulation spacer and is mutually perpendicular to cornerwise both sides, and the arc groove 12 on insulation spacer is processed
On 4 four jiaos of insulation spacer of diagonal line.
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, so that magnetic core 4 is generated deflection, the utility model in cylinder magnetic core by becoming
