Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a split-type shielded metal shell structure. Background Technology

[0002] In the connector manufacturing industry, traditional shielded metal shell structures widely adopt a stamping one-piece molding process. This design concept integrates key functions such as signal transmission, shielding, and mechanical anti-return positioning onto a single part, aiming to achieve functional integration through a compact structure, thereby simplifying production processes and reducing manufacturing costs.

[0003] However, from a practical application perspective, this design has significant drawbacks. Because signal transmission, shielding, and mechanical anti-reverse stop are all located in the same component, the signal transmission path is tightly intertwined with the mechanical structure. When the signal travels through this complex structure, the rigid components of the mechanical anti-reverse structure and the blocking area of ​​the stop design both interfere with signal transmission. The signal frequently encounters different physical environments during transmission, leading to frequent signal abrupt changes. These unstable signal fluctuations severely damage the integrity and stability of the signal, resulting in numerous signal abrupt changes and unstable signal transmission throughout the connector system during use.

[0004] In applications such as 5G communication base stations, high-speed data centers, and precision instruments, where signal stability is extremely critical, unstable connector signal transmission can lead to a series of serious consequences. In 5G base stations, signal instability can cause data packet loss and communication delays, severely impacting communication quality and hindering the efficient operation of the 5G network. In high-speed data centers, the probability of data transmission errors increases significantly, leading to reduced data processing efficiency and affecting the normal operation of the entire data center. In precision testing instruments, signal anomalies can cause deviations in test results, interfering with the accurate evaluation of the tested object. Therefore, the design flaws of traditional one-piece molded shielded metal shell structures have become a key bottleneck restricting connector performance improvement, urgently requiring new design solutions to overcome this predicament.

[0033] The first shielding housing 10 is used for signal transmission and shielding, and is also used to install the signal transmission structure. One end of the first shielding housing 10 can be connected to the board end connector.

[0034] The second shielding housing 20 is used for positioning and fixing the signal transmission structure, and can be installed in conjunction with a plastic housing.

[0035] The first shielding shell 10 and the second shielding shell 20 are both stamped metal parts. The first shielding shell 10 has a first cavity 100 inside, which passes through both ends of the first shielding shell 10. The second shielding shell 20 has a second cavity 200 inside, which passes through both ends of the second shielding shell 20. One end of the first shielding shell 10 is inserted into the second cavity 200 and is fixedly connected to the second shielding shell 20. The signal transmission structure can be installed in the first cavity 100 and the second cavity 200.

[0036] Compared to traditional one-piece stamped shielded metal shell structures, this invention uses a first shielding shell 10 and a second shielding shell 20. The first shielding shell 10 is used for signal transmission and shielding, while the second shielding shell 20 is used for positioning, thus achieving the functions of signal transmission, shielding, and mechanical anti-retraction positioning of the shielded metal shell structure. Furthermore, by placing one end of the first shielding shell 10 inside the second shielding shell 20, and installing the signal transmission structure within the first cavity 100 and the second cavity 200, the signal transmission path does not need to pass through the second shielding shell 20, but only through the first shielding shell 10. This effectively reduces signal interference and abrupt changes, improving the stability of signal transmission. This solves the problems of frequent signal abrupt changes and unstable signal transmission in current one-piece shielded metal shell structures during use.

[0037] like Figure 3 As shown, in order to facilitate the installation between the first shielding housing 10 and the second shielding housing 20, and to facilitate the connection between the first shielding housing 10 and the board end connector, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the first shielding housing 10 includes an integrally formed first housing body 101 and a connecting part 102.

[0041] In one embodiment, it is further preferred that the number of fixed checkpoints 103 is 4.

[0042] like Figure 4As shown, in order to facilitate a more stable connection between the connecting part 102 and the board end connector, the connecting part 102 is provided with a number of mounting windows 104. Each mounting window 104 is provided with a contact spring 105. A contact point 106 is provided between two adjacent mounting windows 104. The contact point 106 is located on the inner side wall of the connecting part 102 and on the inner side wall of the first cavity 100.

The difference from the above embodiment is that the connecting part 102 and the first shell body 101 have a first stamped seam 107. At least one first dovetail connecting structure 108 is provided at the first stamped seam 107 on the first shell body 101.

[0046] In use, the provision of at least one first dovetail connection structure 108 can effectively enhance the overall structural strength of the first shielding shell 10.

[0047] In one embodiment, as a further preferred embodiment, the number of first dovetail connecting structures 108 is two.

The first housing body 101 is inserted into the second housing body 201 and fixedly connected to the second housing body 201. The signal transmission structure can be fixed by the U-shaped crimping wing 202.

[0051] By setting the second shielding shell 20 as an integrally formed second shell body 201 and U-shaped crimping wing 202, during installation, it is only necessary to crimp the U-shaped crimping wing 202 to the signal transmission structure to complete the fixation of the signal transmission structure. At the same time, the setting of the second shell body 201 can facilitate the installation between the second shielding shell and the plastic shell.

[0052] like Figure 6 As shown, in order to facilitate locking and stopping between the second shielding shell 20 and the plastic shell, the second shell body 201 is provided with a primary locking rib 203 and a secondary locking rib 204 arranged sequentially, and a locking groove 205 is provided between the primary locking rib 203 and the secondary locking rib 204.

[0053] In use, the primary locking rib 203, the secondary locking rib 204 and the locking groove 205 facilitate locking and stopping between the second shielding shell 20 and the plastic shell.

[0054] To facilitate locking and positioning between the entire shielding metal outer shell structure and the plastic shell, a shielding shell positioning rib 206 is provided on the second shell body 201. The shielding shell positioning rib 206 is located at one end of the second shell body 201 near the U-shaped crimping wing 202. The entire shielding metal outer shell structure consists of the first shielding shell 10 and the second shielding shell 20.

[0055] During use, the setting of the shielding shell stop rib 206 can facilitate the locking and stopping of the entire shielding metal shell structure and the plastic shell.

[0056] like Figure 6 As shown, in order to enhance the overall structural strength of the second shielding shell 20, this embodiment is modified based on the above embodiment.

At least one second dovetail connecting structure 208 is provided at the second stamped seam 207 on the second shell body 201. The second dovetail connecting structure 208 includes a second dovetail groove and a second dovetail block. The second dovetail groove and the second dovetail block are configured to cooperate with each other.

[0057] In use, the provision of at least one second dovetail connection structure 208 can effectively enhance the overall structural strength of the second shielding shell 20.

[0058] In one embodiment, as a further preferred embodiment, the number of second dovetail connection structures 208 is two.

[0059] like Figure 6 As shown, in order to facilitate a stable connection between the first shielding shell 10 and the second shielding shell 20, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the second shell body 201 is provided with a number of welding points 209, and the first shell body 101 and the second shell body 201 are fixedly connected by welding.

[0060] When connecting the first shielding shell 10 and the second shielding shell 20, it is only necessary to insert the first shell body 101 into the second shell body 201, and then fix it by laser welding at the welding point 209.

[0061] The first stamped joint 107 and the second stamped joint 207 are staggered. This staggered arrangement, where the first shielding shell 10 and the second shielding shell 20 are connected, ensures that the signal transmission structure is completely enclosed, enhancing the shielding effect and anti-interference capability.

[0062] Working principle of this utility model:

[0063] Compared to traditional one-piece stamped shielded metal shell structures, this invention uses a first shielding shell 10 and a second shielding shell 20. The first shielding shell 10 is used for signal transmission and shielding, while the second shielding shell 20 is used for positioning, thus achieving the functions of signal transmission, shielding, and mechanical anti-retraction positioning of the shielded metal shell structure. Furthermore, by placing one end of the first shielding shell 10 inside the second shielding shell 20, and installing the signal transmission structure within the first cavity 100 and the second cavity 200, the signal transmission path does not need to pass through the second shielding shell 20, but only through the first shielding shell 10. This effectively reduces signal interference and abrupt changes, and improves the stability of signal transmission.
