2. Related Art
In general, there are many bosses with different size disposed on the main board. The efficiency of these bosses is to cooperate with a case to fix the main board or to fix other additional elements, which must be fixed on the main board. Due to the development of the main board with stronger and stronger functions, layouts on the main board are also more and more complicated. However, the boss will occupy some layout spaces, which results in the problems of the layout design. Correspondingly, the difficulty of designing the placement of the bosses is increased.
Referring to
However, the above-mentioned combination method needs to manually assemble the boss with the screw or the nut, so that it wastes many labor costs and time. Furthermore, if the elements of the product are unstable combined caused by artificial faults, the product may have element separations in the later usage. In addition, the circular opening on the main board for the combination of the boss is usually utilized as a ground point, which can provide one solution of the Electromagnetic Interference (EMI). However, since the contact area of the boss and the ground point is not enough, this solution may not prevent the EMI efficiently.
As mentioned above, the conventional fixing component of the main board is composed of the hexagonal boss and the screw or the nut. It occupies more area on the main board, so that the layout design becomes harder. Besides, this solution needs to manually combine the elements, which results in the increase of production costs. It is therefore a subjective of the invention to decrease the occupied space of the fixing component on the main board for the more and more complicated layout of the main board, and to shorten the producing time for saving labor costs and time.
In view of the above, the invention is to provide a fixing component, which is disposed on a main board by utilizing SMT and DIP technology.
To achieve the above, a fixing component of a main board of the invention comprises a connecting part, a thread-assembling part, and a fixing part. In the invention, the connecting part has a first surface and a second surface, which is opposite to the first surface. The thread-assembling part is disposed on the first surface of the connecting part. The fixing part is disposed on the second surface of the connecting part. The connecting part and the fixing part is respectively disposed on a circuit board by using SMT and DIP technology.
In addition, the invention also discloses a main board, which comprises a circuit board and at least one fixing component. In the invention, the circuit board has at least a non-circular opening. The fixing component is disposed on the circuit board by using SMT and DIP technology. The connecting part has a first surface and a second surface, which is opposite to the first surface. The thread-assembling part is disposed on the first surface of the connecting part. The fixing part is disposed on the second surface of the connecting part and is connected with the circuit board.
As mentioned above, the fixing component of the main board of the invention is disposed on the main board by utilizing SMT and DIP technology, and has a fixing part requiring a smaller opening on the main board than that of prior art. Therefore, the occupied space on the main board can be reduced, and the disposition of the fixing component can be integrated in a production line with utilizing the SMT and DIP technology. Accordingly, the layout space can be increased and the labor costs can be saved.
The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
The main board and the fixing component thereof of the present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
A fixing component 3 of a main board according to a preferred embodiment of the invention comprises a connecting part 31, a thread-assembling part 32, and a fixing part 33.
Referring to
The thread-assembling part 32 is disposed on the first surface 311 of the connecting part 31. In this embodiment, the thread-assembling part 32 is a female thread-assembling part, which is used to connect with an additional element. Alternatively, the thread-assembling part of the invention can be a male thread-assembling part 32′ as shown in
The fixing part 33 is disposed on the second surface 312 of the connecting part 31, and the connecting part 31 is disposed on a circuit board by utilizing SMT. The fixing part 33 is a non-circular pillar or a polygonal pillar, and is disposed on the circuit board by utilizing DIP technology. In this embodiment, the fixing part 33 is a rectangular pillar. In addition, referring to
The main board of the invention will be described herein below according to
Referring to
The fixing component 3 is disposed around the non-circular opening 40 of the circuit board 20 by utilizing SMT, and then the DIP process is performed to enhance the strength of the fixing component 3 disposed on the circuit board 20. The fixing component 3 comprises a connecting part 31, a thread-assembling part 32, and a fixing part 33.
In this embodiment, the connecting part 31, the thread-assembling part 32, and the fixing part 33 are integrally formed and the connecting part 31, the thread-assembling part 32, and the fixing part 33 are made of conductivity materials. The connecting part 31 has a first surface 311 and a second surface 312, which is disposed opposite to the first surface 311 and is formed with at least one groove 34 thereon. In addition, the connecting part 31 is disposed on the circuit board 20 by utilizing SMT.
The thread-assembling part 32 is disposed on the first surface 311 of the connecting part 31. In this embodiment, the thread-assembling part 32 is a female thread-assembling part. Alternatively, the thread-assembling part of the embodiment can be a male thread-assembling part 32′ as shown in
The fixing part 33, which is a non-circular pillar, is disposed on the second surface 312 of the connecting part 31. In this embodiment, the fixing part 33 is a rectangular pillar, which is used to electrically connect with the rectangular opening of the circuit board 20. After the connecting part 31 is disposed on the circuit 20 by utilizing SMT, the strength of the fixing part 33 is enhanced with DIP technology. Additionally, referring to
In summary, the fixing component of the main board of the invention has the fixing part, e.g. the non-circular pillar, disposed in the non-circular opening of the circuit board, so that the enhanced torque can be obtained between the fixing component and the circuit board. In addition, since the SMT and DIP technology are employed, which utilize solder to electrically connect the fixing component and the circuit board, the effect of grounding of the invention is better than that of prior art, which combines the boss with the screw or nut. Furthermore, since the fixing component is combined with the circuit board by utilizing SMT and DIP technology, the assembling process of the fixing component and circuit board can be integrated with other SMT and DIP processes. Thus, the time and manpower for this assembling process can be saved, and the space occupied by the fixing component can be reduced. Accordingly, the fixing component of the invention is suitable for the present main board, which has the more and more complicated layout.
Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
