Prior art CN2016202102678 discloses a kind of attachment transformer foot type, including skeleton, coil, pin, guarantor
Sheath, skeleton lower part are provided with several pins, and coil is separately connected with pin, 90 ° of pin bendings, and pin can direct patch case
Son is on circuit boards.Prior art CN201720141013X discloses a kind of transformer framework, is related to mobile transformer technology
Field, skeleton theme are respectively arranged on the left side and the right side several pins, and pin is the U-shaped metalwork to fall, and insulate pressure-resistant degree
It is high.However transformer in the prior art, it often not can guarantee enough requirement for horizontality, meet with stresses small.
Utility model content
Based on problems of the prior art, the utility model provides a kind of transformer device structure of arch attachment, can be with
It realizes patch installation requirement, saves manually, and can mass mechanized production；Technique degree of controllability is high in production, and solves
The defects of weldering of pin falseness is easy to appear during patch, reduces the more undesirable wind of craftsmanship during human weld
Danger, and can be improved the stress of pin receiving, increase heat dissipation performance, is suitable for highdensity surface mount, is effectively integrated
The miniaturization and high-performance of transformer.
The technical solution of the utility model is as follows.
A kind of arch mounts transformer device structure, including skeleton, coil, pin, is wound with coil, the skeleton on the skeleton
Lower end surface is equipped with several pins, and pin is extended outwardly by skeleton both side surface and symmetrically divided along skeleton upper surface center line
Cloth, the pin includes the first pin, second pin, third pin, wherein the first pin and third pin are parallel under skeleton
End face, first pin are interconnecting piece, connect coil, and the first pin extends to skeleton lateral direction, other end connection second
Pin, second pin are vertically arranged, and both ends are separately connected the first pin and third pin, and third pin prolongs to skeleton interior direction
It stretches；The lenth ratio of the third pin and the first pin is 1.5:3.5, and the lenth ratio of the first pin and second pin is
1.25-1.5:1。
The pin strong degree within the scope of above-mentioned number ratios is big with the first pin, the first pin and second pin for third pin
It is big to improve, hence it is evident that better than the stress tolerances in the case of other lenth ratios, even under other length ratio relationships, the
In the case that one pin, second pin, third pin connection position increase intensity setting, under the lenth ratio of the utility model
Strong degree will be substantially better than other schemes.
Further, the bottom of the third pin is lower than the level height of skeleton lower end surface.
Further, the pin material is CP line or copper clad steel.
Further, third pin bottom surface is flat horizontal surface, can effectively ensure the requirement of pin levelness.
Further, the pin is provided with two rows, and two opposite sides of skeleton are arranged in, and pin is uniformly distributed, can
To improve secured performance.
Further, the skeleton is bakelite material.
Further, the conducting wire that the coil uses is film packet insulated wire.
Compared with prior art, the utility model has the following technical effects, by changing pin shapes, can make it more
Add and be firmly mounted on the surfaces such as circuit board, improve the stress that pin is born, increases heat dissipation performance, be suitable for highdensity surface
Attachment, has been effectively integrated the miniaturization and high-performance of transformer, has saved manpower, and it is raw to be suitably adapted for large-scale industrialization
It produces, and technique degree of controllability is high, improves the efficiency of production, pin can be installed directly on circuit boards patch, high-efficient, stability
It is high.
