Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device packaging structure, and in particular to a switch packaging housing with an internal PCB support. Background Technology
[0002] Switches are widely used network devices. Structurally, they are mainly divided into box switches and chassis switches. Taking a box switch as an example, its main structure includes an outer casing and internal components. The internal components mainly consist of a PCB and a power supply assembly, which are usually fixed inside the casing (bottom) after drilling holes. There are mounting posts at the bottom of the casing to fix the PCB. However, due to differences in product types and various branch models, the PCB design of switches from different manufacturers also varies, thus requiring casings with different hole positions to match the PCB.
[0003] Because the design of various switch products and their internal PCBs is updated and iterated rapidly, matching housings need to be constantly designed and molded, which not only increases mold-making costs but also adds to the manufacturing process. In addition, the existing internal PCB boards of switches have "hard contact" with the bottom of the housing, and because the bottom does not have a buffer structure, its protection capability is low.
[0004] In view of this, this technical solution proposes a switch enclosure with an internal PCB support. It employs a bottom support structure to secure various PCBs while providing cushioning at the bottom of the PCBs (allowing the PCBs to be "suspended" after assembly). The support can be manufactured separately (or extruded integrally with the enclosure), and its manufacturing cost and process difficulty are far lower than re-molding the entire enclosure. Furthermore, the overall enclosure structure is simple, has good heat dissipation performance, and a long service life. Utility Model Content
[0005] The present invention aims to at least partially solve one of the technical problems in the related technologies. Therefore, the main objective of this invention is to provide a switch enclosure with an internal PCB support, thereby addressing the problems of low compatibility of existing switch enclosures with PCB fixing structures, the need for additional enclosure design, and complex manufacturing processes.
[0006] To achieve the above objectives, this utility model provides a switch packaging housing with an internal PCB support, comprising a housing body consisting of a top cover and a bottom cover.
[0007] The upper cover is connected to one side of the bottom shell and forms a cavity inside for loading the PCB.
[0008] The bottom of the base shell has a bracket protruding into the interior space. The bracket has mounting holes for fixing the PCB. The bracket has support feet for supporting the edge of the PCB at the joint position with the side of the base shell.
[0009] The bracket, support legs, and base shell are detachable.
[0010] The housing body has a wiring hole on one side that communicates with the PCB.
[0011] As a further embodiment of this utility model, the upper cover is provided with a locking hole along its edge, and the inner side of the bottom shell is connected by a locking head that engages with the locking hole to achieve a snap-fit connection.
[0012] As a further embodiment of this utility model, the bottom of the upper cover is provided with a positioning post, and the bottom of the bottom shell is provided with a positioning hole for cooperating and connecting with the positioning post.
[0013] As a further embodiment of this utility model, the bracket has a grid-like structure, and the fixing holes are located at the intersection of the grid-like structure.
[0014] As a further improvement of this utility model, a heat dissipation grid for heat dissipation is provided in the middle of the upper cover and the bottom shell.
[0015] As a further improvement of this invention, the heat dissipation grid is also provided on the side of the bottom shell.
[0016] The beneficial effects of this utility model are as follows:
[0017] This utility model proposes a switch housing with an internal PCB support. Through the support structure, the PCB is secured during installation via the support and mounting holes, eliminating the need for separate mold designs for each PCB model and specification. When adapting a PCB, only the support structure with the corresponding holes needs to be replaced, saving significant costs and reducing manufacturing steps. The housing itself does not use screws for connection; instead, it employs snap-fit holes and clips, preserving the overall structural strength and maintaining an aesthetically pleasing appearance. The switch housing features large-area heat dissipation grilles (top cover, bottom shell, and sides), maximizing heat dissipation and ensuring network operation. Attached Figure Description

[0025] as follows:
[0026] Please see the appendix Figure 1-4 ,
[0027] The main structure includes a housing body 1 consisting of an upper cover 10 and a bottom cover 11. The upper cover 10 is connected to one side of the bottom cover 11 and forms a cavity for loading PCBs inside. The bottom of the bottom cover 11 is provided with a bracket 112 protruding into the internal space. The bracket 112 is provided with a fixing hole 111 for fixing the PCB. The side joint of the bracket 112 and the bottom cover 11 is provided with a support foot 113 for supporting the edge of the PCB. The bracket 112, the support foot 113 and the bottom cover 11 are detachable. One side of the housing body 1 is provided with a wiring hole 115 communicating with the PCB.
[0028] The working principle is as follows:
[0029] In this design, the bracket 112 and support leg 113 serve as replaceable intermediate components for fixing the PCB. Since the hole positions and shapes differ among PCBs of various specifications, redesigning the entire housing (bottom shell 11) to perfectly match each PCB would be wasteful of resources and costly. The bracket 112 structure effectively solves this problem. With the replaceable bracket 112 structure, when assembling PCBs of different specifications and hole positions, only the bracket 112 structure with the corresponding hole positions needs to be manufactured. The bracket 112 structure has fixing holes 111 corresponding to the PCB hole positions, allowing for alignment and fixation. Furthermore, after assembly with the PCB, the bracket 112 and support leg 113 structure leave the PCB in a "suspended" state, thus also acting as a buffer.
[0030] In a preferred embodiment of this utility model, the upper cover 10 is provided with a card hole 100 along its edge, and the inner side of the bottom shell 11 is connected to the card hole 100 by a card head 114.
[0031] The main connection between the top cover 10 and the bottom shell 11 is a snap-fit connection, without using screws or other rigid connections, so as not to damage the structural strength of the shell itself.
[0032] In a preferred embodiment of this utility model, the bottom of the upper cover 10 is provided with a positioning post 101, and the bottom of the bottom shell 11 is provided with a positioning hole 110 for cooperating and connecting with the positioning post 101.
[0033] The positioning column 101 is mainly used to strengthen the overall strength of the structure.
[0034] In a preferred embodiment of this utility model, the bracket 112 has a grid-like structure, and the fixing holes 111 are disposed at the intersection of the grid-like structure.
[0035] Because the switch itself is compact, it uses a thin grid-shaped bracket 112, which serves to fix the installation without increasing the overall weight of the product.
[0036] In a preferred embodiment of this invention, a heat dissipation grid 12 is provided in the middle of the upper cover 10 and the bottom shell 11 for heat dissipation. The heat dissipation grid 12 is also provided on the side of the bottom shell 11.
[0037] The heat dissipation grids 12 set on each side maximize the dissipation of working heat to ensure the normal operation of the equipment.
[0038] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. Any equivalent structural transformations made using the contents of the present utility model specification and drawings under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
