Abstract
Description
Technical Field
[0001] The utility model relates to a circuit device with anti-noise capability and a current transmission structure thereof, in particular to a circuit device with an anti-noise current transmission structure. Background Art
[0002] In the prior art, copper sheets, wires, etc. are used to transmit current or connect different electronic components. However, these connection methods have problems such as difficulty in rework, poor noise suppression, poor heat dissipation of wires, and difficulty in production.
[0003] First, Fig.10 As shown, the copper sheet 71 disposed on the circuit board 70 is used as a conductor (jumper) on the circuit board. This arrangement of the copper sheet 71 has the problem of difficulty in welding, thus causing the risk of poor production yield and production difficulties. Furthermore, since only the copper sheet 71 is used to conduct current, other components to prevent noise interference cannot be added outside or around the copper sheet 71, and due to limited space or other limiting factors, this circuit structure has poor noise suppression ability.
[0004] Secondly, if Fig.11 As shown, the two circuit boards 80 and 81 can also be electrically connected by a copper sheet 82. However, this circuit structure has the same Fig.10 The same problems as the circuit structure with copper sheet conduction, so there are also problems such as difficult rework, poor noise suppression ability, and difficult production.
[0005] Again, if Fig.12 As shown, when two circuit boards 90 and 91 are electrically connected by multiple wires 92, an anti-interference element 93 can be added outside the wires to prevent interference from noise. However, since the cross-sectional area of the wires 92 is much smaller than the copper sheet, it has poor heat dissipation capacity. In addition, since the circuits are numerous and complex, it is also a big challenge to correctly connect each wire 92 to the appropriate position, thus reducing production efficiency.

[0051] In order to understand the technical features, contents and advantages of the present invention and the effects that can be achieved, the present invention is hereby described in detail in the form of embodiments in conjunction with the accompanying drawings. The drawings used therein are only for illustration and auxiliary explanation purposes and may not be the actual proportions and precise configurations after the implementation of the present invention. Therefore, the proportions and configuration relationships of the attached drawings should not be interpreted or limited to the scope of rights of the present invention in actual implementation. This should be stated in advance.
[0052] The following will describe embodiments of the anti-noise circuit device and the current transmission structure thereof according to the present invention with reference to the relevant drawings. For ease of understanding, the same elements in the following embodiments are described with the same symbols.
[0053] like Figure 1 and Figure 2 As shown, the circuit device with an anti-noise current transmission structure of the present invention includes a first circuit component 400 , a second circuit component 500 and an anti-noise current transmission structure 10 ; the anti-noise current transmission structure 10 includes a plurality of anti-interference units 100 and a plurality of conductive elements 200 .
[0054] To further illustrate, a plurality of anti-interference units 100 are arranged between the above-mentioned two circuit components (the first circuit component 400 and the second circuit component 500) for anti-noise interference, and a plurality of through holes 101 are respectively formed in the plurality of anti-interference units 100, and a plurality of conductive elements 200 are respectively arranged in the plurality of through holes 101, wherein each anti-interference unit 100 covers a conductive element 200, and the two circuit components are connected to both ends of the plurality of conductive elements 200, and the conductive elements 200 are used for conduction.
[0055] In one embodiment, the first circuit component 400 and the second circuit component 500 are printed circuit boards, but the present invention is not limited thereto. The first circuit component 400 and the second circuit component 500 may also be two electronic devices, two electrical devices, a circuit board and an electronic device or a circuit device, etc.
[0056] Further explanation, such as Figure 1 and Figure 2 As shown, in one embodiment, the anti-interference unit 100 includes a magnetic material to filter the noise of the source signal (such as a signal from a power supply). In addition, in a preferred embodiment, the anti-interference unit 100 is a filter magnetic ring, so it can be mounted outside the conductive element 200 to prevent interference or generation of noise (such as ripples). In another embodiment, the anti-interference unit 100 can be bonded to at least one of the first circuit component 400 or the second circuit component 500, such as a surface of the first circuit component 400 or the second circuit component 500, but it can also be mounted outside the conductive element 200 as required.
[0057] In addition, in one embodiment, the conductive element 200 includes conductive metals such as gold, silver, and copper; in a preferred embodiment, the conductive element 200 is made of the above conductive metals; in a best embodiment, the conductive element 200 is a copper column.
[0058] Further explanation, in one embodiment, the conductive element 200 is a columnar conductive element 200, such as the copper column in the above embodiment. Since the copper column has a larger cross-sectional area than the wire, it is helpful to reduce the generation of heat energy during current conduction, thereby reducing heat generation. In addition, since the copper column is made of rigid material, the support spacing of the circuit components connected to the two ends of the copper column can also be maintained, avoiding deformation of the board between the circuit components.
[0059] In one embodiment, if Figure 3As shown, the conductive element 200 is in contact with the first conductive portion 401 on the first circuit component 400 and the second conductive portion 501 on the second circuit component 500. In one embodiment, the first conductive portion 401 and the second conductive portion 501 are contacts on the circuit board, which may be exposed metal layers, and the first conductive portion 401 may be arranged around the first through hole 402, and the second conductive portion 501 may be arranged around the second through hole 502. Further explanation, the centers of both ends of the conductive element 200 may be arranged corresponding to the first through hole 402 and the second through hole 502, and may be connected to the first circuit component 400 or the second circuit component 500 by welding as required.
[0060] In one embodiment, if Figure 4 As shown, one end of the conductive element 200 can be connected to the first circuit component 400 by welding, and the other end includes a thread 201 and is locked to the second circuit component 500 through a locking element 300, wherein the locking element 300 is a screw.
[0061] In one embodiment, if Figure 5 As shown, both ends of the conductive element 200 include threads 201 , so that the conductive element 200 can be locked between the first circuit component 400 and the second circuit component 500 through a locking element 300 , wherein the locking element 300 is a screw.
[0062] In one embodiment, if Figure 6 As shown, one end of the conductive element 200 may be connected to the first circuit component 400 by welding (eg Figure 6 The solder paste 60 on the left side is disposed on the second circuit component 500, and the other end includes a thread 201 and penetrates the second circuit component 500 to be locked on the second circuit component 500 through a locking element 300, wherein the locking element 300 is a nut.
[0063] In one embodiment, if Figure 7 As shown, both ends of the conductive element 200 include threads 201. The conductive element 200 penetrates the first circuit component 400 and the second circuit component 500 and is locked between the first circuit component 400 and the second circuit component 500 by a locking element 300, wherein the locking element 300 is a nut.
[0064] In one embodiment, if Figure 8 As shown, the conductive element 200 may be L-shaped in addition to being a straight column as in the above embodiment, so as to connect the first circuit component 400 and the second circuit component 500 arranged relatively in an L-shaped manner. In this case, the anti-interference unit 100 may still be mounted on the conductive element 200 .
[0065] In another embodiment, if Fig. 9As shown, the conductive element 200 can also be arc-shaped to connect the first circuit component 400 and the second circuit component 500 which are arranged relatively in an L-shaped manner. At this time, the anti-interference unit 100 can still be mounted on the conductive element 200. Therefore, the shape of the conductive element 200 is not particularly limited. As long as the conductive element 200 has a larger cross-sectional area than an electric wire and has a supporting effect, it should be included in the scope of the present invention.
[0066] In summary, the circuit device with an anti-noise current transmission structure of the utility model connects at least one end of the conductive element to the circuit board in a locking manner. This method is conducive to production and assembly. In addition, since the shape of this conductive element is simple, it is conducive to the setting of an anti-interference unit (such as a filter magnetic ring), so it can also have an anti-noise effect. In addition, since the cross-sectional area of the conductive element is larger than that of the wire, it can also reduce the heat generated during current conduction and improve the heat dissipation problem.
[0067] The above description is for illustrative purposes only and is not intended to be limiting. Any equivalent modifications or changes made to the present invention without departing from the spirit and scope of the present invention shall be included in the appended claims.
