Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and more specifically, relates to an extension circuit board bracket and electronic equipment. Background Technology

[0002] In electronic devices, various functional expansion circuit boards are typically used to achieve different functions. A robust and reliable electrical connection needs to be established between these expansion circuit boards to ensure the normal operation of the electronic device. Traditionally, jumpers are used to connect the expansion circuit boards. While jumper connections can meet basic signal transmission requirements to some extent, their drawbacks include a messy wiring layout. This not only affects the aesthetics of the internal components but, more importantly, increases the risk of signal interference, potentially leading to decreased signal transmission quality and impacting overall device performance. Furthermore, jumper connections have relatively low reliability and stability, and are prone to loosening or damage over long-term use, requiring frequent maintenance and replacement, increasing equipment upkeep costs. Another method uses copper busbars to connect the expansion circuit boards, but the assembly process for copper busbars is relatively cumbersome and not conducive to proper electrical signal connections between the expansion circuit boards.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 3 and Figure 6 As shown, this application provides an extension circuit board bracket, including an insulating housing 1 and a conductive element 3.

[0049] Specifically, the insulating housing 1 is the main structure of the expansion circuit board bracket, specifically having at least two mounting areas 11 for mounting expansion circuit boards 2, so as to ensure that multiple expansion circuit boards 2 can be placed on the expansion circuit board bracket at the same time.

[0050] Conductive component 3 is manufactured through injection molding process (e.g. Figure 3 and Figure 4 (as shown) or hot melt process (such as) Figure 7 and Figure 8 As shown, etc., are placed inside the insulating housing 1 and are integral with the insulating housing 1. This not only improves the insulation performance of the conductive component 3 and the structural strength of the expansion circuit board bracket, but also effectively reduces the number of required parts and simplifies the assembly process.

[0051] In one specific embodiment of this application, the conductive element 3 includes a connecting portion 31 and at least two conductive contacts. Each conductive contact is disposed in a corresponding mounting area 11 for electrical connection with a corresponding expansion circuit board 2. The connecting portion 31 is electrically connected to each conductive contact, thereby realizing electrical signal connection between each expansion circuit board 2. The connecting portion 31 may specifically be strip-shaped or line-shaped, and each conductive contact is arranged sequentially along the length direction of the connecting portion 31.

[0052] like Figure 3 and Figure 6 As shown, in one specific embodiment of this application, the conductive element 3 further includes a protrusion 32. The protrusion 32 extends into the mounting area 11, and the conductive contact is disposed on the protrusion 32. By raising the spatial position of the conductive contact through the protrusion 32, the conductive contact can be brought closer to the expansion circuit board 2, thereby making it easier to establish a direct electrical connection with the expansion circuit board 2.

[0053] like Figure 3 and Figure 6 As shown in a specific embodiment of this application, the protruding post 32 is further provided with a connecting hole 33. The connecting hole 33 serves to provide an installation interface for installing conductive fasteners, thereby establishing an electrical connection path between the protruding post 32 and the expansion circuit board 2. Specifically, conductive fasteners are generally conductive screws. In the actual assembly process, the expansion circuit board 2 is first placed in the mounting area 11; then, the pre-set electrical connecting hole on the expansion circuit board 2 is adjusted to be completely aligned with the connecting hole 33 on the protruding post 32; after alignment, the conductive screw is screwed into the corresponding electrical connecting hole and connecting hole 33. As the conductive screw is tightened, not only is a fastening connection between the expansion circuit board 2 and the protruding post 32 achieved, but also a reliable electrical connection between the two is established through the conductive characteristics of the conductive screw.

[0054] like Figure 3 and Figure 6 As shown, in one specific embodiment of this application, a reinforcing rib 12 is provided on one side of the insulating shell 1, and the reinforcing rib 12 is sleeved on one end of the protruding post 32. The primary function of the reinforcing rib 12 is to provide effective insulation protection for the protruding post 32. Specifically, the reinforcing rib 12 covers most of the area of ​​the protruding post 32, leaving only the position of the conductive contact point, thereby ensuring the transmission of electrical signals and preventing the risk of short circuit due to accidental contact, thus improving electrical safety. In addition, the reinforcing rib 12 can also increase the connection stability and structural strength between the protruding post 32 and the insulating shell 1.

[0055] like Figure 4 and Figure 6 As shown, in a specific embodiment of this application, the other side of the insulating housing 1 is also provided with a through hole 13, which corresponds to the other end of the protruding post 32, so that the main circuit board 4 of the electronic device can be connected to the protruding post 32 or the connection hole 33 on the protruding post 32 through the through hole 13.

[0056] like Figure 5 As shown, in one specific embodiment of this application, the insulating housing 1 is further provided with pin header holes 14. The pin header holes 14 are used for the pins on the main circuit board 4 to pass through the insulating housing 1. The pin header holes 14 guide the pins, effectively preventing connection failures or performance degradation caused by path deviations or improper angles. In addition, the pin header holes 14 provide support after the pins are inserted, making the connection between the pins and the pin holder more secure and effectively preventing loosening or detachment caused by vibration or external forces.

[0057] like Figure 5As shown in a specific embodiment of this application, the inner wall of the pin header hole 14 is provided with limiting teeth 15. When the pin header is inserted into the pin header hole 14, the limiting teeth 15 correspond to the slots on the pin header, which not only ensures the accuracy of the pin header's position in the pin header hole 14, but also provides stable support and guidance for the pin header through the interaction between the limiting teeth 15 and the slots, effectively avoiding poor connection or performance degradation caused by positional offset or angular deviation.

[0058] like Figure 3 As shown, in one specific embodiment of this application, the insulating housing 1 is further provided with a guide protrusion 16. The guide protrusion 16 is used to extend into the positioning hole 21 on the expansion circuit board 2, so as to guide and position the expansion circuit board 2 before the pin headers make formal contact with the pin header holes 14 on the insulating housing 1.

[0059] like Figure 3 As shown, in one specific embodiment of this application, the insulating housing 1 further includes a hook portion 17. The base end of the hook portion 17 is connected to the insulating housing 1, and the hook end of the hook portion 17 is hooked to the expansion circuit board 2. Specifically, the hook end of the hook portion 17 can hook onto the edge of the expansion circuit board 2 or a reserved hole, thereby achieving a stable connection between the expansion circuit board 2 and the insulating housing 1, effectively preventing the expansion circuit board 2 from loosening or falling off due to vibration, impact, or other factors.

[0060] This application also provides an electronic device including the expansion circuit board bracket of the above embodiments, and therefore also has the advantages of the expansion circuit board bracket of the above embodiments. Figure 1 and Figure 2 As shown, the expansion circuit board bracket is fixed to the main circuit board 4 or other support structures of the electronic device by fasteners or snap-fit ​​structures.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
