Description

Technical Field

[0001] The utility model relates to a cable shielding shell and a data connecting line, belonging to the technical field of data lines. Background Art

[0002] USB data cable is the mainstream data cable at present. Its advantages are convenience, speed and stability. USB is the most widely used external bus standard in the PC field. It is used to regulate the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swap functions of devices. Mobile phones on the market are generally equipped with USB data cables. Consumers generally charge them through USB data cables with power adapters, or directly connect them to computers through USB data cables for charging, or connect them to computers through USB data cables for data transmission. The ability of data cables to shield electronic signals is the key to determining the stability of data cable transmission signals.

[0003] Among the data cables with shielding function currently on the market, Figure 1 As shown, for the convenience of connection, the braided net of the cable shielding layer is often twisted into a section, that is, twisted into a "pigtail"-shaped braid, and a long section of the core wire is exposed from the shielding layer, which will produce a "pigtail" effect, greatly reducing the shielding effect of the shielding layer. At the same time, this cable cannot suppress common mode radiation well. For example, a 1cm long "pigtail" has a 30% risk, a 3cm long "pigtail" has a 50% risk, and a 5cm long "pigtail" has a 70% risk. It is difficult for existing data cables to achieve overall full shielding, which results in weak anti-signal interference ability of the transmission line head when transmitting signals.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] The technical solution, its implementation process and principle will be further explained below in conjunction with the accompanying drawings.

[0038] Example 1

[0039] See also Figure 2 and Figure 4 A cable shielding shell includes a shielding shell 100, an input terminal 210 and an output terminal 220, one end of the input terminal 210 is connected to one end of the output terminal 220 and a connection structure 230 is formed at the connection, the shielding shell 100 is wrapped with an inner mold layer 110, a shielding layer 120, a double-sided metal conductive layer 130, and an outer mold layer 140 from the inside to the outside, and the inner mold layer 110 wraps the connection structure 230.

[0040] In this embodiment, one end of the input terminal 210 and one end of the output terminal 220 are connected, wherein the input terminal 210 can be a wire and the output terminal 220 can be a USB interface. One end of the wire is connected to the contact of the USB interface, and the connection structure 230 is formed at the connection. Then, the inner mold layer 110 is used to completely wrap the connection structure 230, and then the shielding layer 120 is wrapped on the outer surface of the inner mold layer 110 to shield electromagnetic interference. The double-sided metal conductive layer 130 is wrapped on the outer surface of the shielding layer 120, and finally, the outer mold layer 140 is wrapped on the outer surface of the double-sided metal conductive layer 130. The inner mold layer 110, the shielding layer 120, the double-sided metal conductive layer 130 and the outer mold layer 140 constitute a shielding shell 100, and the connection structure 230 of the input terminal 210 and the output terminal 220 is wrapped in the shielding shell 100. In addition, the ends of the input terminal 210 and the output terminal 220 opposite to the connection structure 230 are exposed from the shielding shell 100, so as to facilitate subsequent use.

[0041] In the above structure, the shielding shell 100 includes an inner mold layer 110, a shielding layer 120, a double-sided metal wire layer and an outer mold layer 140 from the inside to the outside. The inner mold layer 110 wraps the connection structure 230 at the connection between the input terminal 210 and the output terminal 220. The inner mold layer 110 can effectively protect the connection structure 230 to prevent the connection structure 230 from being disconnected due to external forces. In addition, it can also effectively prevent impurities such as water and dust from entering the connection structure 230, which may easily cause short circuit problems. The shielding layer 120 is wrapped around the outside of the inner mold layer 110, which can effectively shield electromagnetic and other electronic signal interference. Among them, a double-sided metal conductive layer 130 is also wrapped around the outside of the shielding layer 120. Both sides of the double-sided metal conductive layer 130 have a conductive effect. When the external electronic interference signal interferes with the connection structure 230, it is first transmitted to the outer side of the double-sided metal conductive layer 130. The outer side of the double-sided metal conductive layer 130 can guide the external electronic signal to the inner side of the double-sided metal conductive layer 130, and transmit it to the inner shielding layer 120, and the shielding layer 120 guides the electronic signal to the ground wire. The double-layer shielding structure is realized by the double-sided metal conductive layer 130 and the shielding layer 120, which improves the shielding effect per unit area of ​​the shielding shell 100, thereby improving the overall electrical connectivity and further improving the electronic signal shielding effect. Since the shielding layer 120 and the double-sided metal conductive layer 130 wrap the connection structure 230 inside, the "pig tail effect" is further reduced. Finally, the outer mold layer 140 is used to wrap the double-sided metal conductive layer 130 to further protect the double-sided metal conductive layer 130 and the shielding layer 120 .

[0042] In addition, in this embodiment, the input terminal 210 is a wire and the output terminal 220 is a USB interface. This is only one embodiment. In other embodiments, the input terminal 210 can also be any one of a USB-A interface, a USB-B interface, a micro USB interface, a Type-C interface, and a Lightning interface, and the output terminal 220 can also be any one of a wire, a USB-A interface, a USB-B interface, a micro USB interface, a Type-C interface, and a Lightning interface.

[0043] In the specific structure of the double-sided metal conductive layer 130, the double-sided metal conductive layer 130 wraps the shielding layer 120, and the gap of the double-sided metal conductive layer 130 is welded by the tin wire 150. The double-sided metal conductive layer 130 is a double-sided conductive copper foil structure. The double-sided conductive copper foil structure has good conductivity. In addition, it can be welded with the tin wire 150. When in use, the double-sided metal conductive layer 130 is covered and wrapped on the shielding layer 120, wherein there will be a certain gap between the wrapped double-sided metal conductive layer 130, and then the tin wire 150 is welded in the gap, so that the double-sided metal conductive layer 130 can completely wrap the shielding layer 120, further improving the shielding effect. When the double-sided metal conductive layer 130 is wrapped around the shielding layer 120, there will be a certain gap. When the outer mold layer 140 is injected, the mold material is easy to enter the gap, causing a certain impact on the double-sided metal conductive layer 130, which is easy to cause the double-sided metal conductive layer 130 to deform, destroy the shielding structure, and cause the shielding to fail. In addition, the double-sided metal conductive layer 130 can also be a conductive metal structure that can be welded with tin wire, and the tin wire 150 is an environmentally friendly tin wire such as lead-free tin wire 150.

[0044] In the specific structure of the shielding layer 120, the shielding layer is a mesh cover structure woven from tinned copper braided wires, which can better guide external electronic interference signals.

[0045] In the specific structure of the inner mold layer 110 and the outer mold layer 140, the inner mold layer 110 is an injection molded structure formed by injection molding to wrap the connection structure 230, and the outer mold layer 140 is an injection molded structure formed by injection molding to wrap the double-sided metal conductive layer 130. Both the inner mold layer 110 and the outer mold layer 140 can be made by injection molding. After the input terminal 210 and the output terminal are connected to form the connection structure 230, the input terminal 210, the connection structure 230, and the output terminal 220 are placed in the corresponding mold, and the inner mold layer 110 is made by injection molding and the connection structure 230 is wrapped therein. The injection molding process can make the inner mold layer 110 completely wrap the connection structure 230, thereby improving the sealing effect and protection effect of the connection structure 230, and further protecting the connection structure 230. Similarly, after wrapping the double-sided metal conductive layer 130 in the shielding layer 120, the whole is placed in a corresponding mold, and then the outer mold layer 140 is made through an injection molding process to completely wrap the double-sided metal conductive layer 130, thereby improving the sealing and protection effects of the double-sided metal conductive layer 130 and the shielding layer 120.

[0046] The inner mold layer 110 and the outer mold layer 140 are made of PVC, TPU, TPE, nylon, etc., which makes them have good toughness and protection.

[0049] In this embodiment, according to different usage environments and usage conditions, the extension direction of the input terminal 210 and the extension direction of the output terminal 220 can be different directions. In order to effectively reduce the occupied space and reduce the number of times the cable shielding shell is pulled, the first direction and the second direction are set to be perpendicular to each other, that is, the extension direction of the output terminal 220 is perpendicular to the extension direction of the input terminal 210. The overall shape of the shielding shell 100 is adapted to the position and shape of the output terminal 220 and the input terminal 210. In this embodiment, the orthographic projection of the shielding shell 100 is an "L"-shaped structure, so as to better adapt to the positional relationship between the input terminal 210 and the output terminal 220, and the inner mold layer 110, the shielding layer 120, the double-sided metal conductive layer 130 and the outer mold layer 140 are also made into an orthographic projection of an "L"-shaped structure, so as to improve the wrapping of the connecting structure 230.

The structures of the plurality of output terminals 220 in the second group are consistent or inconsistent.

In addition, the structures of the three output terminals 220 of the second group are inconsistent, for example, the three output terminals 220 are respectively microUSB interfaces, Type-C interfaces, and Lightning interfaces, so that the data connection line can be connected to multiple devices with different interfaces at the same time.
