Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a connector with signal shielding function. Background Technology

[0002] Connectors are widely used in the electronics field to achieve reliable connections between electronic terminal devices and between electronic terminal devices and power supplies. The performance of connectors directly affects whether the entire electronic device works properly. Therefore, connectors play a vital role in the entire electronics field. USB connectors are also a type of signal connector. With their high transmission speed, support for hot-plugging, and ability to connect multiple devices, USB connectors have been widely used in various external devices.

[0003] However, traditional USB connectors, although they have a protective shell, do not provide good protection for the connector's plug end when in use. When not in use, the plug end is exposed and easily damaged by bumps. In addition, the connection cable does not have a protective structure, and long-term use will inevitably lead to breakage due to bending.

[0004] Furthermore, it lacks signal shielding capabilities, making the USB connector susceptible to interference from external electronic components during use, which in turn can disrupt normal signal transmission. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a connector with signal shielding function, which has the following beneficial effects:

[0018] 1. By setting up a connector, plug, square groove and protective cover, when the connector is not in use, the spring will push the protective cover out so that one end of it covers the plug, thereby protecting the plug and reducing external wear. When plugging in, the protective cover is compressed by external force, which will cause the spring to compress and the protective cover to detach from the plug, making it convenient to use.

[0019] 2. By setting up a flexible tube, connecting plate, and connecting screw, the user can insert the plug into the slot on the protective shell and make the connecting plate contact the tail end of the protective shell. Then, the connecting screw is screwed into the threaded hole by the screwing block to fix the flexible tube. At this time, the flexible tube will shield and protect the root of the transmission line to reduce wear at the connection point with the protective shell during bending, thereby preventing cracking and helping to ensure long-term use.

[0020] 3. By setting an internal high-density layer, a signal insulation layer, and an external high-density layer, the connector's anti-interference and shielding capabilities during signal transmission can be enhanced, thereby providing a good signal transmission environment for the connector and making it convenient to use.

[0031] Please see Figure 1-6 A connector with signal shielding function includes a protective shell 1, a connector 2 inside the protective shell 1, a plug 3 fixedly attached to one end of the connector 2, a transmission line 4 fixedly attached to the tail end of the protective shell 1, one end of the transmission line 4 being electrically connected to the connector 2, a square groove 5 between the protective shell 1 and the connector 2, a slide rod 6 fixedly attached to the inner wall of the square groove 5 on both sides, a spring 7 sleeved on the outer end of each slide rod 6, the bottom of each spring 7 being fixedly connected to the inner wall of the square groove 5, a protective cover 8 slidably attached inside the square groove 5, the protective cover 8 being slidably installed with the slide rod 6, the other end of the spring 7 being fixedly connected to the tail end of the protective cover 8, a flexible tube 9 sleeved on the outer end of the transmission line 4, and anti-slip protrusions 19 fixedly attached to both sides of the protective shell 1, the protective cover 8 being able to shield the plug 3.

[0032] In this embodiment, a connecting plate 10 is fixedly provided at one end of the flexible tube 9. An insert block 11 is provided on the inner wall of the connecting plate 10. A slot 12 is correspondingly provided on the outer wall of the protective shell 1. The insert block 11 is located inside the slot 12. Threaded holes 13 are correspondingly provided on the outer walls of both the connecting plate 10 and the protective shell 1. A connecting screw 14 is provided inside the threaded hole 13. A screwing block 15 is fixedly provided at one end of each connecting screw 14.

[0033] More specifically, when the connector is not in use, the spring 7 will push the protective cover 8 out, so that one end of it covers the connector 3, thereby protecting the connector 3 and reducing external wear. When plugging in, the protective cover 8 is compressed by the external force, which causes the spring 7 to compress, thus detaching the protective cover 8 from the connector 3 for easy use. The plug block 11 can also be inserted into the slot 12 on the protective shell 1, and the connecting plate 10 can be made to contact the tail end of the protective shell 1. Then, the connecting screw 14 is screwed into the threaded hole 13 through the screwing block 15 to fix the hose 9. At this time, the hose 9 will cover and protect the root of the transmission line 4, reducing wear at the connection point with the protective shell 1 during bending, thereby preventing breakage and contributing to long-term use.

[0034] Please see Figure 1 and Figure 6 As an embodiment that enables the device to have signal shielding function: an inner high-density layer 16 is provided on the outer wall of the connector 2, a signal insulation layer 17 is provided on the outer wall of the inner high-density layer 16, and an outer high-density layer 18 is provided on the outer wall of the signal insulation layer 17. The inner high-density layer 16 and the outer high-density layer 18 are made of shielding tape, and the signal insulation layer 17 is made of polyvinyl chloride material.

[0035] Specifically, the internal high-density layer 16, the signal insulation layer 17, and the external high-density layer 18 can enhance the anti-interference and shielding capabilities of the connector 2 when transmitting signals, thereby providing a good signal transmission environment for the connector and making it convenient to use.

[0036] Please refer to Figure 1 As a further embodiment for guiding the protective cover 8: both sides of the protective cover 8 are provided with sliders 20, and both sides of the protective shell 1 are provided with grooves 21, and the sliders 20 and the grooves 21 are slidably installed.

[0037] Specifically, the slider 20 and the groove 21 can guide the protective cover 8 to make it move more smoothly.

[0038] In summary, when using the entire device: the plug 11 can be inserted into the slot 12 on the protective shell 1, and the connecting plate 10 can be brought into contact with the tail end of the protective shell 1. Then, the connecting screw 14 can be screwed into the threaded hole 13 through the screwing block 15 to fix the hose 9. At this time, the hose 9 will shield and protect the root of the transmission line 4, reducing wear at the connection point with the protective shell 1 during bending, thereby preventing breakage and contributing to long-term use. When the plug 3 is pulled out, the spring 7 will push the protective cover 8 out. One end of the protective cover 8 is shielded from the connector 3, thereby protecting the connector 3 and reducing external wear. During insertion, the protective cover 8 is compressed by external forces, causing the spring 7 to detach from the connector 3 for easy use. The outer wall of the connector 2 is also provided with an inner high-density layer 16, a signal insulation layer 17, and an outer high-density layer 18, which can enhance the anti-interference and shielding capabilities of the connector 2 when transmitting signals, thereby providing a good signal transmission environment for the connector and making it convenient to use.
