DETAILED DESCRIPTION
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically depicted in order to simplify the drawings.
FIG. 1 is a perspective view of an electronic device 100 according to one embodiment of this invention. FIG. 2 is an exploded view of the electronic device 100 of FIG. 1. FIG. 3 is an exploded view of a fixing member 140 and a terminal 130 of FIG. 2. As shown in FIG. 1 to FIG. 3, an electronic device 100 is provided. The electronic device 100 includes at least one electronic component 110, a connected member 120, at least one terminal 130, and at least one fixing member 140. The terminal 130 is electrically connected to the electronic component 110 and the connected member 120. The terminal 130 includes a body 132, a coupling portion 134, and a coupling portion 136. The coupling portions 134 and 136 are disposed on the body 132 of the terminal 130. The fixing member 140 is connected to the electronic component 110. The fixing member 140 includes a body 142, a coupling portion 144, and a coupling portion 146. The body 142 of the fixing member 140 has a first surface 142F and a second surface 142S connected to the first surface 142F, and a normal direction of the first surface 142F and a normal direction of the second surface 142S are interlaced with each other. The coupling portion 144 is disposed on the first surface 142F, for being detachably coupled with the coupling portion 134, such that degrees of freedom in a first direction D1 and a second direction D2 of the terminal 130 are restricted. The coupling portion 146 is disposed on the second surface 142S, for being detachably coupled with the coupling portion 136, such that a degree of freedom in a third direction D3 of the terminal 130 is restricted. The first direction D1, the second direction D2, and the third direction D3 are linearly independent. The terminal 130 includes a connecting end 138, and the connecting end 138 is electrically connected to a connecting wire 116 which extends from the electronic component 110.
As shown in FIG. 2 and FIG. 3, the body 142 of the fixing member 140 has a notch 148 therein. A nut 150 which has a tapped hole HN therein is accommodated in the notch 148. The connected member 120 has a through hole HTH1 therein. The body 132 of the terminal 130 has a through hole HTH2 therein. In the assembling process, a screw 155 passes the through hole HTH1 of the connected member 120 and then the through hole HTH2 of the body 132 of the terminal 130 and then coupled with the nut 150. Specifically, in the embodiment, when the nut 150 is accommodated in the notch 148, the coupling portion 134 is coupled with the coupling portion 144, and the coupling portion 136 is coupled with the coupling portion 146, the tapped hole HN of the nut 150 is connected to the through hole HTH2 of the body 132 of the terminal 130, such that the screw 155 may pass the through hole HTH1 of the connected member 120 and the through hole HTH2 of the body 132 of the terminal 130 and be coupled with the nut 150.
More specifically, as shown in FIG. 3, the fixing member 140 is a housing, and the housing at least partially covers the electronic component 110. People having ordinary skill in the art can make proper modification to the fixing member 140 according to their actual needs.
As shown in FIG. 3, the coupling portion 134 may be a protruded coupling portion, and the coupling portion 144 may be a recessed coupling portion. With the shape matching, the coupling portion 134 may be detachably coupled with the coupling portion 144. By restricting the degrees of freedom in the first direction D1 and the second direction D2 of the coupling portion 134, the degrees of freedoms in the first direction D1 and the second direction D2 of the terminal 130 is restricted as well. People having ordinary skill in the art can make proper modification to the shape according to their actual needs. In other embodiments, the coupling portion 134 may be a recessed coupling portion, and the coupling portion 144 may be a protruded coupling portion. The key point is that the degrees of freedoms in the first direction D1 and the second direction D2 of the terminal 130 can be restricted.
As shown in FIG. 3, the coupling portion 136 may be a recessed coupling portion, and the coupling portion 146 may be a protruded coupling portion. Similarly, with the shape matching, the coupling portion 136 may be detachably coupled with the coupling portion 146. By restricting the degree of freedom in the third direction D3 of the coupling portion 136, the degree of freedom in the third direction D3 of the terminal 130 is restricted as well. People having ordinary skill in the art can make proper modification to the shape according to their actual needs. In other embodiments, the coupling portion 136 may be a protruded coupling portion, and the coupling portion 146 may be a recessed coupling portion. The key point is that the degree of freedom in the third direction D3 of the terminal 130 can be restricted.
Because the first direction D1, the second direction D2, and the third direction D3 are linearly independent, when the degrees of freedom in the first direction D1, the second direction D2, and the third direction D3 are all restricted, the terminal 130 is stably fixed. The terminal 130 includes the connecting end 138, the connecting wire 116 extends from the electronic component 110, and the connecting end 138 is electrically connected to the connecting wire 116, such that the electronic component 110 is electrically connected to the terminal 130. The connecting end 138 may be connected to the connecting wire 116 by riveting or welding, and the connecting wire 116 may be a single-strand or multi-strand wire. Specifically, when the electronic component 110 is an electromagnetic induction module, the connecting wire 116 may be a wire extending from a coil. As shown in FIG. 2 and FIG. 3, in the embodiment, four terminals 130 are coupled with the body 142 of the fixing member 140 (the housing).
In the embodiment, the connected member 120 is a printed circuit board. Correspondingly, as shown in FIG. 2, a plurality of through holes HTH1 are disposed on the printed circuit board (the connected member 120), and the position of the through holes HTH1 correspond to the through holes HTH2 of the body 132 of the terminal 130. When the coupling portion 134 is coupled with the coupling portion 144 and the coupling portion 136 is coupled with the coupling portion 146, as shown in FIG. 3, the tapped hole HN of the nut 150 is connected to the through hole HTH2 of the body 132 of the terminal 130. At that time, the assembly worker may use the screws 155 to fix the printed circuit board (the connected member 120) to the body 132 of the terminal 130. The assembly worker first passes the screw 155 through the through hole HTH1 in the printed circuit board (the connected member 120) and then pass the screw 155 through the through hole HTH2 of the body 132 of the terminal 130. Then, the assembly work couples the screw 155 with the nut 150. As shown in FIG. 3, because the shape of the notch 148 matches the nut 150, the nut 150 cannot rotate in the notch 148. Therefore, when the screw 155 is being coupled with the nut 150, the screw 155 may rotate with respect to the nut 150, such that the coupling of the screw 155 and the nut 150 may be performed successfully. The notch 148 may be a hexagonal column or a polygonal column.
As mentioned above, when the screw 155 is coupled with the nut 150, the printed circuit board (the connected member 120) is fixed to the body 132 of the terminal 130. The printed circuit board (the connected member 120) has a connecting portion, and the through hole HTH1 is disposed in the connecting portion. The connecting portion is electrically connected to at least one electronic component 110 (the connected member 120) on the printed circuit board. The terminal 130 is conductive, the printed circuit board (the connected member 120) is electrically connected to the terminal 130 by the connecting portion, and the terminal 130 is electrically connected to the electronic component 110. Therefore, the electronic component 110 is electrically connected to the printed circuit board (the connected member 120).
Because the nut 150 is restricted in the notch 148 by the terminal 130, the screw 155 as well as the connected member 120 is restricted by the terminal 130 after the nut is coupled with the screw 155. And because the degrees of freedom in the first direction D1, the second direction D2, and the third direction D3 of the terminal 130 is restricted, and the terminal 130 is stably fixed to the fixing member 140 (the housing). Therefore, in the embodiment, the connected member 120 is stably fixed to the fixing member 140 (the housing).
In order to easily couple or detach the coupling portion 134 with the coupling portion 144 and to easily couple or detach the coupling portion 136 with the coupling portion 146, in the embodiment, the body of the fixing member 140 (the housing) has a recessed portion 149, for providing an assembling space. The second surface 142S of the body 142 of the fixing member 140 (the housing) is at least one inner surface of the recessed portion.
FIG. 4 is a perspective view of an assembling surface 142A of the fixing member 140 of FIG. 2.

Specifically, the first surface 142F is a top surface opposite to the assembling surface 142A. The fixing member 140 may be assembled to the electronic component 110 by gluing, coupling, or other appropriate methods.
Though in FIG. 3, the second surface 142S is at least one inner surface of the recessed portion 149, people having ordinary skill in the art can make proper modification according to their actual needs. FIG. 5 is an exploded view of the fixing member 140 and the terminal 130 according to another embodiment of this invention. In another embodiment shown in FIG. 5, the second surface 142S is a side surface connected to the first surface 142F. The key point is that the terminal 130 can be coupled with the fixing member 140.
In the embodiment, the electronic component 110 includes at least one electromagnetic inductive device 113 such as an inductor or a transformer. People having ordinary skill in the art can make proper modification to the electronic component 110 according to their actual needs.
In another embodiment, the fixing member 140 is a bobbin, and at least one coil 114 is wound around the bobbin which is known by people having ordinary skill in the art. FIG. 6 is an exploded view of the fixing member 140 and the terminal 130 according to another embodiment of this invention. As shown in FIG. 6, the fixing member 140 (the bobbin) includes a body 142, the coupling portion 144, and the coupling portion 146. The body 142 of the fixing member 140 (the bobbin) has a first surface 142F and a second surface 142S connected to the first surface 142F, and a normal direction of the first surface 142F and a normal direction of the second surface 142S are interlaced with each other. The coupling portion 144 is disposed on the first surface 142F, for being detachably coupling with the coupling portion 134 of the terminal 130, such that the degrees of freedom in the first direction D1 and the second direction D2 of the terminal 130 are restricted. The coupling portion 146 is disposed on the second surface 142S, for being detachably coupling with the coupling portion 136 of the terminal 130, such that the degree of freedom in the third direction D3 of the terminal 130 is restricted. The first direction D1, the second direction D2, and the third direction D3 are linearly independent. The terminal 130 includes a connecting end 138, a connecting wire 116 extends from the coil 114, and the connecting end 138 is electrically connected to the connecting wire 116, such that the coil 114 is electrically connected to the terminal 130. As shown in FIG. 6, in the embodiment, two terminals 130 are coupled with the body 142 of the fixing member 140 (the bobbin).
Similarly, in the embodiment, the body 142 of the fixing member 140 (the bobbin) has a notch 148 therein, for accommodating the nut 150. When the nut 150 is accommodated in the notch 148, the coupling portion 134 is coupled with the coupling portion 144, and the coupling portion 136 is coupled with the coupling portion 146, the tapped hole HN of the nut 150 is connected to the through hole HTH2 of the body 132 of the terminal 130.
Though the second surface 142S is a specific side surface connected to the first surface 142F in FIG. 6, people having ordinary skill in the art can make proper modification according to their actual needs. FIG. 7 is an exploded view of the fixing member 140 and the terminal 130 according to another embodiment of this invention.
