Transformer Skeleton BOBBIN System Functions To Introduce You To Know

Skeleton, also known as the transformer skeleton, or the transformer wire frame, English collectively referred to as Bobbin, is the main part of the transformer structure. Transformer in today's society is widely used, corresponding to the main body is also essential, so the current skeleton has no substitute for the role of. Tell you a bakelite skeleton manufacturer adams!

The role of the skeleton in the transformer mainly has the following several points:

1： to provide winding space for the copper wire in the transformer,

2： magnetic cores in fixed transformers.

3： the wire slot in the frame provides a path for the transformer to provide a line of winding.

4：the metal pin in the skeleton is the backbone of the transformer, and is connected with the PCB board after soldering tin, which is conductive to the transformer.

5： at the bottom of the wall frame, can make the transformer fixed function and PCB board; for when soldering tin stack and PCB board and PCB board, and the core, provide a certain distance space; isolated core and tin heap, avoid the occurrence of adverse pressure.

Bump, 6 skeleton concave points or angle, can be used to determine the transformer pin placement direction or order.

According to the general framework used by the core transformer (or core) type classification, EE, EF, EPC, PQ, UU and other models, and each model and according to the core (or core) to distinguish the size, such as EE10, EE13, EE19 etc. the size of the model. According to the shape of the skeleton is divided into two kinds of vertical and horizontal; according to the operating frequency of the transformer is divided into high frequency and low frequency of two kinds of skeleton skeleton, the frequency does not refer to the frequency of use, but refers to the transformer at work when the number of periodic changes, Hertz (Hz), also referred to as Hector. KHz MHz (kHz) or (MHz) or GHz units; according to the skeleton of the pins in nature, is divided into the traditional framework (DIP) and Esther chip (SMD) framework two.

It is precisely because the skeleton has so many features, its shape can be described as the ever-changing. With a skeleton, such as the EE-19 vertical line bakelite skeleton, after specific to a classification so fine, the skeleton has at least a dozen. There is a height of the retaining wall is not the same, and some of the wire slot is different, even the most important and the most critical dimension PIN distance and row spacing, are not the same. In this way, the supply and demand sides of the skeleton have caused many difficulties. A little difference between the size of the existing mold can not be used. A simple point to cooperate with the new part of the new open mold, the complex point of the whole set of mold have to be re opened. Greatly improve the transformer production costs, in the industry, because they can not find a suitable mold, and led to the transformer factory can not meet the single case often appear. Many transformer factory friends have a consensus on all the constituent materials of transformer, is not easy to find the skeleton. For skeleton factory, he developed a number of sets of molds, because there is no order placed on the shelf idle, but do not know some of the transformer factory because of this product can not find the mold and give up the hand of the order.

In view of this situation, all the members of the BOBBIN forum, as well as the skeleton industry several veterans, after repeated research, design and development of transformer skeleton online query system, this system based on the classification of the unique way of the skeleton skeleton were divided into several classes, and then according to the matching core specification and PIN foot features. The simplest possible way to find the most accurate results, the bridge to the skeleton plant and transformer factory to build a information.
