Description

Technical Field

[0001] This utility model relates to the field of network connectors, and in particular to a confined space twisting and riveting structure for an OSFP connector. Background Technology

[0002] OSFP (Octal Small Form-factor Pluggable) connectors are a high-performance, high-density optical module interface standard designed to meet the high-speed data transmission needs of data centers and network equipment. The design of OSFP connectors allows for higher port density within limited space. This means that more OSFP modules can be installed in the same size panel or device, increasing data transmission capacity. OSFP connectors support data transmission rates up to 400Gbps and above, making them a key component for meeting the high-speed bandwidth requirements of modern data centers and network equipment. This high-speed transmission capability helps improve the overall performance and efficiency of the network. With continuous technological advancements, OSFP connectors are expected to play an even more important role in future network infrastructure.

[0003] As the number of ports on OSFP connectors continues to increase, the size of their housings is also growing, resulting in a longer lateral length. In these housings, both the base and top plates are single, elongated strips. The longer the strip, the less stable the overall structure becomes. Furthermore, both the base and top plates are riveted to the internal spacer, requiring ample unobstructed space above the riveting points for the tooling fixtures to perform the riveting operation. This significantly increases the overall manufacturing difficulty of the housing. Therefore, it is necessary to improve the current OSFP connector housing design. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a confined space twisting and riveting structure for OSFP connectors, which can effectively solve the problems of unstable shell structure and high manufacturing difficulty of existing OSFP connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A confined space twist-and-rivet structure for an OSFP connector includes two half-shells and a middle frame. The two half-shells are symmetrically arranged, and the middle frame connects the two half-shells. Each half-shell has multiple middle walls on the side near the middle frame, arranged vertically at intervals. Each middle wall has two vertically spaced layers, and each layer has multiple first rivet points extending outward from its outer side, arranged front-to-back at intervals. The middle frame includes a middle shell and a middle connecting piece. The middle shell is U-shaped and includes two vertical plates, the rear sides of which are integrally connected by a rear plate. The forming and bending connection consists of two vertical plates that extend vertically and are symmetrically arranged left and right, forming a narrow space between the two vertical plates. Multiple first rivet holes are formed through both sides of each vertical plate. These multiple first rivet points pass through the corresponding first rivet holes, extend into the narrow space, and are twisted and riveted to be fixed with the corresponding vertical plate. The connecting piece is U-shaped and includes two horizontal plates. The front sides of the two horizontal plates are integrally formed and bent together by a front plate. The two horizontal plates extend horizontally and are symmetrically arranged up and down. One horizontal plate is fixedly connected to the upper side of the two vertical plates, and the other horizontal plate is fixedly connected to the lower side of the two vertical plates.

[0007] As a preferred option, multiple first rivet points on two adjacent middle walls are directly opposite each other.

Correspondingly, multiple through holes are opened at the top and bottom edges of the half shell, and multiple second rivet holes are opened on the left and right sides of the two horizontal plates. The multiple second rivet points extend outward from the corresponding horizontal plates through the corresponding through holes and the corresponding second rivet holes, and are riveted and fixed at 90° to the corresponding horizontal plates.

[0011] As a preferred embodiment, the left and right sides of the front panel are bent at 90° and extend out with multiple support parts arranged vertically at intervals, and the multiple support parts are respectively supported and abutted against the corresponding vertical panels.

[0012] As a preferred embodiment, each of the two shell halves has a central partition that extends vertically. The central partition has multiple central walls on both the left and right sides. The central partition has multiple third rivet holes, and correspondingly, multiple third rivet points extend from the central walls. The multiple third rivet points are arranged at intervals and pass through the corresponding third rivet holes to be bent and riveted to the central partition at a 90° angle.

[0013] As a preferred embodiment, the central wall is U-shaped, and the central wall is formed by folding the tail end of a sheet material to form two layers of sheet.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] By incorporating a middle frame that connects the two half-shells, the overall structure of this product becomes more stable and reliable. Furthermore, the middle shell and the half-shells are fixed and connected by riveting using a twisting method, replacing the traditional large-area riveting structure, making the product easier to manufacture and bringing convenience to production operations.

[0036] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including two half-shells 10 and a middle frame 20.

[0037] The two half-shells 10 are arranged symmetrically from left to right. Each half-shell 10 has multiple central walls 11 on the side near the middle frame 20. These central walls 11 are arranged vertically at intervals. Each central wall 11 has two vertically spaced layers 111. Multiple first rivets 101 extend outward from the outer side of each layer 111. These first rivets 101 are arranged front to back at intervals. In this embodiment, the multiple first rivets 101 on two adjacent central walls 11 are directly opposite each other. Furthermore, the central wall 11 is U-shaped, and it is formed by folding the end of a sheet metal to create two layers 111.

[0038] The middle frame 20 connects the two half-shells 10. The middle frame 20 includes a middle shell 21 and a middle connecting piece 22. The middle shell 21 is U-shaped and includes two vertical plates 211. The rear sides of the two vertical plates 211 are integrally formed and bent together by a rear plate 212. The two vertical plates 211 extend vertically and are symmetrically arranged from left to right. A narrow space 200 is formed between the two vertical plates 211. The width of the narrow space 200 in the left-right direction is about 5-20mm. Multiple first rivet holes are formed through both sides of each vertical plate 211. 201. The plurality of first rivet points 101 extend through the corresponding first rivet holes 201 into the narrow space 200 and are fixedly riveted to the corresponding vertical plate 211 by twisting and riveting. The connecting piece 22 is U-shaped and includes two horizontal plates 221. The front sides of the two horizontal plates 221 are integrally formed and bent together by a front plate 222. The two horizontal plates 221 extend horizontally and are arranged symmetrically up and down. One horizontal plate 221 is fixedly connected to the upper side of the two vertical plates 211, and the other horizontal plate 221 is fixedly connected to the lower side of the two vertical plates 211. In this embodiment, the plurality of first rivet points 101 on the same half shell 10 are arranged in multiple rows front and back. Each row of first rivet points 101 consists of a plurality of first rivet points 101 arranged vertically at intervals. The twisting directions of two adjacent rows of first rivet points 101 are opposite, so as to make the riveting more stable and reliable. Furthermore, the first rivet points 101 have a semi-open structure, which makes the riveting simpler and the connection more stable. It should be noted that when the width between the two vertical plates 211 is large enough, the first rivet point 101 can also be riveted and fixed to the first rivet hole 201 by flat pressing, without limitation.

[0039] Furthermore, multiple second rivet points 202 extend from the upper and lower sides of both vertical plates 211, and these second rivet points 202 are arranged at intervals. Correspondingly, multiple through holes 103 are provided on the top and bottom edges of the half-shell 10, and multiple second rivet holes 203 are provided on the left and right sides of both horizontal plates 221. The multiple second rivet points 202 extend outward from the corresponding horizontal plates 221 through the corresponding through holes 103 and the corresponding second rivet holes 203, and are riveted and fixed at a 90° angle to the corresponding horizontal plates 221. This makes the combined connection structure of the two horizontal plates 221 and the two vertical plates 211 simple and the connection stable and reliable. Additionally, one horizontal plate 221 overlaps on the opposite top edges of the two half-shells 10, and the other horizontal plate 221 overlaps on the opposite bottom edges of the two half-shells 10, clamping and fixing the two half-shells 10 together. In addition, the front panel 222 has multiple support portions 204 arranged vertically at intervals on both its left and right sides, which are bent at 90°. These support portions 204 support the corresponding vertical plates 211 to stabilize the overall structure of the middle frame 20. Furthermore, the front panel 222 has multiple slots 205 arranged vertically at intervals.

[0040] In addition, each of the two halves of the shell 10 has a central partition 12, which extends vertically. The central partition 12 has multiple central walls 11 on both the left and right sides. The central partition 12 has multiple third rivet holes (not shown in the figure). Correspondingly, multiple third rivet points 102 extend from the central wall 11. The multiple third rivet points 102 are arranged at intervals. The multiple third rivet points 102 pass through the corresponding third rivet holes and are bent and riveted to the central partition 12 at 90°.

[0041] The assembly process of this embodiment is described in detail below:

[0042] First, the two half-shells 10 are riveted and assembled, and the middle shell 21 and the middle connecting piece 22 are stamped and formed. Next, the two half-shells 10 are arranged symmetrically from left to right, and the middle shell 21 is placed between the two half-shells 10. At the same time, each first rivet point 101 extends into the narrow space 200 through the corresponding first rivet hole 201. Then, the vertically extending rivet head is inserted into the narrow space 200 from the upper or lower opening to perform a twisting riveting on each first rivet point 101. This allows the two vertical plates 211 to be fixedly connected to the two half shells 10 respectively. Then, the middle connecting piece 22 is placed on the front side of the middle shell 21 and between the two half shells 10, so that multiple second rivet points 202 pass through the corresponding second rivet holes 203 and extend outward to the corresponding horizontal plate 221. Then, each second rivet point 202 is riveted at 90°, so that the middle connecting piece 22 is fixedly connected to the middle shell 21 to form the middle frame 20. At this time, the middle frame 20 is stably connected between the two half shells 10.

[0043] The key design feature of this invention is that by providing a middle frame that connects the two half-shells, the overall structure of the product becomes more stable and reliable. Furthermore, the middle shell and the half-shells are fixed and connected by riveting using a twisting method, which replaces the traditional large-area riveting structure, making the product easier to manufacture and bringing convenience to production operations.

[0044] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
