The transformer of indispensable important feature, the prior art is mainly made of bobbin, magnetic core, armature winding and secondary windings,
Although its can meet demand to a certain extent, in transport, the pin on bobbin is easy to damage because of touching, shadow for it
Ring transformer normal use, while transformer welding on circuit boards when, had between bobbin and circuit board it is certain between
Gap, long-time influences the normal use of transformer in use, dust etc. is readily adsorbed on pin, so applicability and reality
It is restricted with property.
Summary of the invention
Reasonable and strong applicability the transformer device structure the purpose of the utility model is to provide a kind of structure setting.
The technical solution for realizing the utility model aim is a kind of transformer device structure, including bracket, is arranged in the bracket
Interior iron core is wound with primary coil and secondary coil on the iron core, and the end of the bracket is provided with pin, described
Primary coil, secondary coil the end of a thread be fixed on pin, the bottom surface of the bracket is provided with ring groove, the annulus is recessed
Slot is arranged centered on pin, and protection cylinder is provided in the ring groove, and the top of the protection cylinder is in described
It is fixed in ring groove and between the roof of the ring groove and the roof of protection cylinder and compresses spring, in the bracket
On be provided with the circular hole being connected with the ring groove roof, drag-line, the inside of the drag-line are provided in the circular hole
End is fixed on the roof of the protection cylinder, in welding pin, cylinder will be protected to be pulled upwardly by drag-line recessed to annulus
In slot.
The protection cylinder is less than the depth of ring groove with whole height when compressing spring-compressed.
The protection cylinder is dielectric plastic material body.
It is provided with heat conduction silicone on the inner wall of the protection cylinder, the pin passes through in the heat conduction silicone
Heart setting.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, and it is convenient not only to operate, if
It is equipped with protection cylinder, in transport, pin is in protection cylinder, can avoid damage to pin, and weld on circuit boards
On, it protects the bottom surface of cylinder to be pressed on the top surface of circuit board, is also possible to prevent dust etc. and is adsorbed on pin, advantageously ensure that
Transformer uses reliability, strong applicability and practicability is good.
Detailed description of the invention
In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached

The end of a thread 6 be fixed on pin 5, the bottom surface of the bracket is provided with ring groove 7, the ring groove is centered on pin
Setting, is provided with protection cylinder 8 in the ring groove, the top of the protection cylinder be in the ring groove it is interior and
It is fixed between the roof of the ring groove and the roof for protecting cylinder and compresses spring 9, be provided on the bracket and institute
The circular hole 10 that ring groove roof is connected is stated, drag-line 11 is provided in the circular hole, the inner end of the drag-line is fixed on
On the roof of the protection cylinder, in welding pin, cylinder will be protected to be pulled upwardly to ring groove by drag-line.This reality
It applies in example, drag-line can be insulating material body, or metal iron wire etc. can according to need and be selected.
The protection cylinder is less than the depth of ring groove with whole height when compressing spring-compressed.
The protection cylinder is dielectric plastic material body.
It is provided with heat conduction silicone 12 on the inner wall of the protection cylinder, the pin passes through the heat conduction silicone
Center setting.
The structure setting of the utility model is reasonable, and it is convenient not only to operate, and is provided with protection cylinder, in transport, pin
In protection cylinder, pin can be avoided damage to, and is welded on circuit boards, the bottom surface of cylinder is protected to be pressed on circuit
It on the top surface of plate, is also possible to prevent dust etc. and is adsorbed on pin, advantageously ensure that transformer uses reliability, is applicable in
The strong and practicability of property is good.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
