Detailed Description
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, like reference numerals indicate like or similar parts and features. The drawings are only schematic representations of the concepts and principles of the embodiments of the present invention, and do not necessarily depict the specific dimensions and proportions of the various embodiments of the invention, as may be exaggerated in particular drawings or in particular portions thereof to show relevant details or structures of various embodiments of the present invention.
Fig. 1 shows an electronic product in the prior art when a potting process is performed using a circuit board support assembly. The circuit board support assembly according to the prior art includes a bolt 20, a supporter 40, and a nut 60. The bolt 20 is inserted into the housing 10 through the bolt hole 12 provided in the bottom portion 11 of the housing 10 such that the head 21 of the bolt 20 abuts against the outside of the bottom portion 11 of the housing 10. Although not shown in the drawings, it is conceivable for those skilled in the art to provide a seal between the head 21 of the bolt 20 and the bottom 11 of the housing 10 for sealing. The bolts 20 also serve as fixing means for mounting the entire electronic product into the chassis. After passing through the housing 10, the bolt 20 passes through the seat 13 protruding inward from the inner side of the bottom 11 of the housing 10. Subsequently, the bolt 20 passes through the support hole in the first printed circuit board 31. The bolt 20 then passes through the support 40. The bolt 20 also acts as a ground so that the bolt 20 and the support 40 are coaxial. The support member 40 is generally cylindrical. The end of the support 40 close to the seat 13 comprises a neck section 41. The neck section 41 passes through the above-mentioned support hole in the first printed circuit board 31. The end of the neck section 41 is flared to form a flared portion 411. The flared portion 411 is flared radially outward after passing through the first printed circuit board 31, and abuts against the upper end surface of the holder 13. The support 40 also includes an intermediate section 42. The flared portions 411 of the intermediate section 42 and the neck section 41 each abut against the first printed circuit board 31, thereby clamping the first printed circuit board 31 between the intermediate section 42 and the flared portions 411. The flared portion 411 abuts against an end of the holder 13, thereby disposing the first printed circuit board 31 and the support 40 clamped on the first printed circuit board 31 within the housing 10. Two supports 40 are shown in fig. 1. However, it will be appreciated by those skilled in the art that more than two supports 40 may be provided. With the above configuration, the first printed circuit board 31 is fixed.
In order to fix the second printed circuit board 32 in the electronic product, the support 40 comprises a constricted section 43 at the end opposite the neck section 41. The constricted section 43 passes through a support hole in the second printed circuit board 32 so that the intermediate section 42 abuts against the second printed circuit board 32. Meanwhile, a fixing plate 70 is provided at an end of the case 10 opposite to the bottom 11. The fixing plate 70 has an outer peripheral edge engaged with an end portion of the housing 10 opposite to the bottom 11. A fixing hole 71 through which the bolt 20 passes is provided in the fixing plate 70. A cylindrical fixing boss 72 protrudes from the inner side of the fixing plate 70 to the inner side of the electronic product around the fixing hole 71. The securing boss 72 abuts the second printed circuit board 32, thereby clamping the second printed circuit board 32 between the securing boss 72 and the intermediate section 42 of the support 40. The constricted section 43 of the support 40 penetrates into the fastening boss 72. The fixing hole 71 of the fixing plate 70 is provided with a recess 73 at the outer side of the fixing plate 70. The nut 60 is screw-engaged with the bolt 20 and is screwed against the bottom of the recess 73, thereby fixing the first printed circuit board 31, the second printed circuit board 32 and the support member 40 in the housing 10 and tightly fitting the fixing plate 70 with the housing 10.
After the fixing plate 70 is fixed to the housing 10, potting filler is injected into the housing 10 through a potting port provided in the fixing plate 70 in the direction of the arrow shown in the drawing to perform potting. At the same time, the gas inside the housing is exhausted through a plurality of exhaust ports (not shown) provided on the fixing plate 70 until the potting filler overflows from the fixing plate 70, thereby ensuring complete potting of the product. After the potting is completed, the fixing plate 70 needs to be strongly removed, thereby reducing the weight of the product and reducing the cost of the product. Since the fixing plate 70 is bonded with the potting filler after the potting is completed, the strong removal of the fixing plate 70 increases man-hours, costs, and risks, and affects the beauty.
Fig. 2 shows a circuit board support assembly according to a first embodiment of the present invention. The circuit board support assembly according to the first embodiment of the present invention includes a bolt 20, a support 40, a first sleeve 51, a second sleeve 52, and a nut 60. The bolt 20 is inserted into the housing 10 through the bolt hole 12 provided in the bottom portion 11 of the housing 10 such that the head 21 of the bolt 20 abuts against the outside of the bottom portion 11 of the housing 10. The inside of the housing 10 of the electronic product is not provided with the holder 13 but with the first sleeve 51. One end of the first sleeve 51 abuts against the inside of the bottom 11 of the housing 10. The other end of the first sleeve 51 abuts against the first printed circuit board 31, and is provided with a concave portion 511 at the other end. The bolt 20 passes through the first sleeve 51. The omission of the support 13 from the housing 10 makes the configuration of the housing 10 simpler, reducing man-hours and cost. Also, the size of the first sleeve 51 can be selected as appropriate to accommodate different electronic products.
As shown in fig. 2, the bolt 20 passes through the first printed circuit board 31 and the support member 40 after passing through the first sleeve 51. Fig. 3 shows in particular the support 40 and the second sleeve 52 according to a first embodiment of the invention. The support member 40 is generally cylindrical. The support 40 is formed with a neck section 41, an intermediate section 42, and an expansion section 44 from one end to the other end of the support 40, respectively, along the axial direction of the support 40, and the outer diameter of the neck section 41, the outer diameter of the intermediate section 42, and the outer diameter of the expansion section 44 increase in this order. The end of the support 40 adjacent the first sleeve 51 is a neck section 41. The recess 511 of the first sleeve 51 is capable of at least partially receiving the neck section 41.
As shown in fig. 2, the middle section 42 passes at least through the support hole in the second printed circuit board 32 after installation. The second sleeve 52 is disposed over the intermediate section 42. One end of the second sleeve 52 abuts against the first printed circuit board 31, thereby clamping the first printed circuit board 31 between the first sleeve 51 and the second sleeve 52. The other end of the second sleeve 52 abuts against the second printed circuit board 32. The length of the second sleeve 52 may be appropriately sized as needed to adjust the spacing between the first printed circuit board 31 and the second printed circuit board 32. It will be appreciated by those skilled in the art that the first sleeve 51 and the second sleeve 52 may be made of a metallic material or a non-metallic material.
As shown in fig. 2, one end of the expanding section 44 of the supporting member 40 abuts against the second printed circuit board 32, and the other end abuts against the nut 60, thereby clamping the second printed circuit board 32 between the second sleeve 52 and the expanding section 44. The nut 60 is threadedly engaged with the bolt 20, thereby fixing the first and second printed circuit boards 31 and 32 in place. The circuit board support assembly of the present invention may be used for spacing between printed circuit boards. Compared with the fixing mode in the prior art, the invention can simplify the fixation during the encapsulation because a fixing plate is not needed. In addition, the electronic product manufactured by the circuit board supporting assembly has a very flat surface after being encapsulated, so that the working hours are reduced, and the cost is reduced. In addition, the circuit board support assembly of the present invention can be flexibly applied to different electronic products by processing the sleeve.
When the circuit board support assembly is used for more than two printed circuit boards, the length of the support assembly and the number of the sleeves are increased.
Fig. 4 shows a circuit board support assembly according to a second embodiment of the present invention. The circuit board support assembly according to the second embodiment of the present invention includes a bolt 20, a support 40, a first sleeve 51, a second sleeve 52, a third sleeve 53, and a nut 60. Fig. 5 shows in particular the support 40, the second sleeve 52 and the third sleeve 53 according to a second embodiment of the invention. As shown in fig. 4, in order to mount the additional third printed circuit board 33, the length of the middle section 42 of the support member 40 is increased. The middle section 42 passes through a support hole in the third printed circuit board 33. A third sleeve 53 is provided between the second printed circuit board 32 and the third printed circuit board 33. The third sleeve 53 is disposed over the intermediate section 42. Thereby, the second printed circuit board 32 is sandwiched between the second sleeve 52 and the third sleeve 53, and the third printed circuit board 33 is sandwiched between the third sleeve 53 and the expanding section 44. The flared section 44 abuts the nut 60. The nut 60 is threadedly engaged with the bolt 20 to fix the first, second and third printed circuit boards 31, 32 and 33 in place.
When the electronic product is encapsulated along the arrow directions shown in fig. 2 and fig. 4, for example, the specific amount of the encapsulating filler can be known through the early-stage sample, the encapsulation can be quantitatively carried out according to the amount in batch production, the height of the upper surface of the encapsulating filler can be observed or detected at any time during encapsulation, and whether the encapsulating filler overflows or not can be controlled in time.
Although the circuit board support assembly of the present invention has a more significant advantage when applied to more than two printed circuit boards, it is apparent that the circuit board support assembly of the present invention can be applied to only one printed circuit board.
