The present disclosure relates to a bobbin of a magnetic module, and more particularly to a modular bobbin that can be detachably and pivotally connected.
In general, the structure of a multiple winding transformer includes a plurality of bobbins connected with each other, and the bobbins are connected by male and female buckles, and thus the assembling process takes more time, and the male and female buckles may be broken easily when removing the buckles. In addition, the bobbins of the conventional multiple winding transformer are fixed after they are assembled, so that a wire cannot be wound from one bobbin to the other, or a core cannot be installed between the bobbins. As a result, most conventional multiple winding transformers require a plurality of conductive wires wound around the bobbins respectively, and then the core is installed between the bobbins, and the conductive wires are soldered and electrically conducted with one another.
In view of the aforementioned drawbacks of the conventional multiple winding transformer, the inventor of the present disclosure based on years of experience in the related industry, and finally developed a magnetic module and a bobbin of the magnetic module in accordance with the present disclosure to overcome the drawbacks of the prior art.
Therefore, it is a primary objective of the present disclosure to provide a magnetic module and a modular bobbin applied in the process of winding a plurality of bobbins by a single wire.
To achieve the aforementioned objective, the present disclosure provides a magnetic module comprising a modular bobbin, a core module and a conductive wire. The modular bobbin comprises a first bobbin and a second bobbin, and the first bobbin includes a first shaft, and a first pivoting portion and a first snapping portion disposed at an end of the first shaft and arranged on two opposite sides of the end of the first shaft respectively, and the second bobbin includes a second shaft coaxially installed with the first shaft, and a second pivoting portion and a second snapping portion disposed at an end of the second shaft and arranged at two opposite sides of the end of the second shaft respectively, and the second pivoting portion is pivotally coupled to the first pivoting portion, and/or the second snapping portion is detachably latched to the first snapping portion, so that the first bobbin and the second bobbin may be pivoted and rotated by the first pivoting portion and the second pivoting portion to separate the second snapping portion from the first snapping portion, and/or the first bobbin and the second bobbin may be pivoted and rotated by the first snapping portion and the second snapping portion to separate the second pivoting portion from the first pivoting portion. The core module includes an inner core, and the inner core is situated between the first bobbin and the second bobbin when the second snapping portion is separated from the first snapping portion. The conductive wire is wound around the first shaft and the second shaft.
Preferably, the first shaft has a first flapper, and the first pivoting portion is disposed at the first flapper, and the second shaft has a second flapper, and the second pivoting portion is disposed at the second flapper, and the inner core is installed between the first flapper and the second flapper. Preferably, a first wire crossing slot is formed at an end of the first flapper, and a second wire crossing slot is formed at an edge of the second flapper.
Preferably, the conductive wire includes a wire crossing section, and a first winding section and a second winding section are extended from both ends of the wire crossing section and wound around the first shaft and the second shaft respectively, and the wire crossing section is disposed between the first flapper and the second flapper, and both ends of the wire crossing section are contained into the first wire crossing slot and the second wire crossing slot respectively. Preferably, the first wire crossing slot and the first pivoting portion are disposed adjacent to each other, and the first wire crossing slot is formed at a position corresponsive to the position of the second wire crossing slot, and the second wire crossing slot and the second pivoting portion are arranged adjacent to each other.
Preferably, the first bobbin is connected to a second bobbin in different ways. For example, the first pivoting portion is a hook and the second pivoting portion is a cam pivotally coupled to the hook, or the first pivoting portion is a cam and the second pivoting portion is a hook pivotally latched to the cam. In other examples, the first pivoting portion and the second pivoting portion are a pair of hooks latched with each other, or the first snapping portion and the second snapping portion are a pair of hooks latched with each other. In other examples, the first snapping portion is a hook and the second snapping portion is a cam latched to the hook, or the first snapping portion is a cam and the second snapping portion is a hook latched to the cam.
In the present disclosure, the first pivoting portion is pivotally coupled to the second pivoting portion, so that the first bobbin and the second bobbin can be pivoted with respect to each other, and a single conductive wire may be wound around the first shaft and the second shaft and then the first bobbin and the second bobbin are pivotally rotated and separated from each other to facilitate manufacturers to install the inner core between the first bobbin and the second bobbin. Compared with the prior art, the present disclosure is able to complete the process of winding two connected bobbins by a single conductive wire, and the modular bobbin of the present disclosure can be applied in the process of winding two or more bobbins.
The technical contents of the present disclosure will become apparent with the detailed description of preferred embodiments accompanied with the illustration of related drawings as follows. It is noteworthy that same numerals are used for representing same respective elements in the drawings.
