DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See Figures 1 to 4As shown, an embodiment of the present invention provides an electronic device 1, which includes a combined circuit board and a housing 20; the housing 20 is provided with a mounting cavity 201, and the housing 20 is further provided with a first fixing post 202 and a second fixing post 203 in the mounting cavity 201; the combined circuit board includes a first circuit board 100, a second circuit board 200 and a connecting structure 300, wherein the second circuit board 200 and the first circuit board 100 are arranged perpendicular to each other and the second circuit board 200 is arranged on one side of the first circuit board 100; the connecting structure 300 includes a contact 310 and a contact piece, wherein the contact 310 is provided on the first circuit board 100 and electrically connected to the first circuit board 100, and the contact piece is provided on the second circuit board 200 and electrically connected to the second circuit board 200, and the extension direction of the contact 310 is provided parallel to at least one of the first circuit board 100 and the second circuit board 200, and the contact 310 and the contact piece are in contact and electrically connected; the first circuit board 100 is connected to the first fixing post 202, and the second circuit board 200 is connected to the second fixing post 203.

[0034] In the electronic device of this embodiment, the combined circuit board can electrically connect the first circuit board 100 and the second circuit board 200, which are perpendicular to each other, by providing contacts 310 and contact pieces. The electrical transmission function between the first circuit board 100 and the second circuit board 200 can be achieved without the need for high-precision welding technology, thereby simplifying the structure and optimizing the manufacturing cost.

[0035] In one embodiment, the contact 310 includes a solder pad 311 and an elastic portion 312, the solder pad 311 is welded to the first circuit board 100, the elastic portion 312 is electrically connected to the solder pad 311, and the end of the elastic portion 312 away from the first circuit board 100 is movably arranged relative to the first circuit board 100, and the elastic portion 312 is used to contact and electrically connect with the contact piece.

[0036] With this arrangement, when assembling the electronic device 1 of this embodiment, first, either the first circuit board 100 or the second circuit board 200 is connected to the corresponding fixing post in the housing 20. Then, in the process of connecting the other circuit board to its corresponding fixing post, the elastic portion 312 can contact the contact piece under the elastic action and be compressed during the assembly process. After the first circuit board 100 and the second circuit board 200 are installed in place, the contact 310 and the contact piece can maintain a tight contact under the elastic action of the elastic portion 312, thereby ensuring the reliability and stability of the electrical connection between the first circuit board 100 and the second circuit board 200. When the combined circuit board needs to be disassembled and maintained, no additional disassembly action is required. During the process of separating the first circuit board 100 or the second circuit board 200, the contact 310 and the contact piece can be separated to disconnect the electrical connection between the first circuit board 100 and the second circuit board 200, making disassembly and assembly convenient.

[0037] Specifically, the elastic portion 312 includes a retractable elastic pin and a spring, the spring being connected to the pad 311 and the retractable elastic pin respectively. The retractable elastic pin is slidably connected to the pad 311 and is used to contact and electrically connect with the contact piece.

[0038] In this embodiment, by arranging a spring and a telescopic elastic pin, the spring can provide an elastic force for the telescopic elastic pin to drive the telescopic elastic pin to have an elastic tendency to move toward the contact piece, and maintain a pressing force between the contact 310 and the contact piece when the contact 310 contacts the contact piece; of course, in this embodiment, a cylindrical conduit is provided inside the solder pad 311, and the telescopic elastic pin is also a cylindrical structure. At this time, the spring is accommodated in the conduit, and the telescopic elastic pin also slides with the conduit.

[0039] In one embodiment, the housing 20 defines a receiving cavity 204 . The receiving cavity 204 is located between the first fixing post 202 and the second fixing post 203 , and the contact 310 is accommodated in the receiving cavity 204 .

[0040] With this arrangement, when assembling the first circuit board 100, the contact 310 can be positioned for installation by setting the accommodating cavity 204 to cooperate with the contact 310. At the same time, since the accommodating cavity 204 is arranged around the contact 310, the four sides of the contact 310 can also be protected to avoid accidental separation of the contact 310 from the first circuit board 100 when the electronic device 1 vibrates.

[0041] Specifically, the housing 20 further includes a limiting portion 2041 connected to the inner wall of the accommodating cavity 204 . When the first circuit board 100 is connected to the first fixing column 202 , the limiting portion 2041 abuts against the end of the contact 310 .

[0042] When assembling the electronic device 1 of this embodiment, by providing the stopper 2041 to cooperate with the contact 310, once the first circuit board 100 is installed, the stopper 2041 can abut against the outer surface of the contact 310 to position the contact 310. This structure can be applied to a housing 20 in which the depth of the accommodating cavity 204 is greater than the thickness of the contact 310. It can also determine the installation height of the contact 310 based on the designed position of the contact 310 (here, the height refers to the end surface of the stopper 2041 relative to the depth of the accommodating cavity 204), thereby improving the installation stability of the contact 310. Of course, during the normal installation process, when the first circuit board 100 is connected to the first fixing post 202 via components such as screws, the first circuit board 100 can also be tightened against the first fixing post 202. In this case, the stopper 2041 abuts against the other side of the contact 310 to support the contact 310.

[0043] Furthermore, the housing 20 is further provided with a mounting groove 2042 . The mounting groove 2042 is communicated with the accommodating cavity 204 , and a portion of the structure where the contact 310 is connected to the contact piece is accommodated in the mounting groove 2042 .

[0044] In this embodiment, the elastic portion 312 of the contact 310 can be accommodated within the mounting groove 2042. The elastic portion 312 cooperates with the mounting groove 2042 to position the elastic portion 312, thereby improving the installation accuracy of the first circuit board 100. Furthermore, by using the mounting groove 2042 to position the elastic portion 312, the connection stability of the contact 310 can be improved, preventing accidental breakage. In a preferred embodiment, the opening of the mounting groove 2042 is chamfered to facilitate assembly when the elastic portion 312 and the mounting groove 2042 are combined.

[0045] Specifically, a positioning groove 110 is defined at the edge of the first circuit board 100 , and a positioning rib 205 is defined in the mounting cavity 201 of the housing 20 . The positioning rib 205 is engaged with the positioning groove 110 .

[0046] In this embodiment, by providing positioning ribs 205 that cooperate with the positioning grooves 110 of the first circuit board 100, the installation position of the first circuit board 100 within the installation cavity 201 can be positioned, thereby improving the installation convenience of the first circuit board 100. In a preferred embodiment, there are multiple sets of positioning grooves 110 and positioning ribs 205, and the multiple positioning grooves 110 are arranged at intervals along the edge of the first circuit board 100. By providing multiple sets of positioning grooves 110 and positioning ribs 205, the installation accuracy and convenience of the first circuit board 100 can be further improved.

[0047] In one embodiment, a fixing slot 206 is further defined inside the housing 20 , and the second circuit board 200 is plugged into and engaged with the fixing slot 206 . The extending direction of the fixing slot 206 is parallel to the second fixing post 203 .

[0048] In this embodiment, the first circuit board 100 is arranged parallel to the shell 20, and the second circuit board 200 is arranged perpendicular to the first circuit board 100. By setting a fixing groove 206 inside the installation cavity 201, during the assembly process, the second circuit board 200 can be inserted into the fixing groove 206 to position the installation of the second circuit board 200.

[0049] Furthermore, the electronic device 1 further includes a fastener 30 detachably connected to the second fixing column 203 , with an end face of the fastener 30 abutting against the second circuit board 200 , and an axis of the fastener 30 being arranged parallel to the second circuit board 200 .

[0050] With this arrangement, the second circuit board 200 can be installed and positioned through the fixing groove 206. After the second circuit board 200 is installed in the fixing groove 206, the fastener 30 is abutted against the outer surface of the second circuit board 200 and connected to the second fixing column 203, thereby fixing the second circuit board 200 to the shell 20. The structure is simple and easy to assemble and disassemble, and there is no need to open additional positioning holes on the second circuit board 200.
