[0002] Gigabit network, with its advantages of fast speed, high stability and relatively low cost, is one of the most commonly used communication interfaces in data centers, industrial control and communication fields. The most commonly used RJ45 (Registered Jack 45) interface connector is used in the Gigabit network signal wiring system. The RJ45 interface connector consists of a plug (crystal head) and a socket, which is convenient and easy to use. Therefore, in some military and industrial control products, RJ45 interface sockets are also configured as network communication interfaces to facilitate communication with different types of equipment.

[0003] In the relevant technology, the RJ45 interface is a standard interface for civil and commercial use, with high openness, but poor electromagnetic shielding performance and tolerance to harsh environments, far lower than the aviation plug connectors commonly used in the military and industrial fields.

[0026] like Figure 1 As shown, the present invention discloses an outdoor distribution box, the standard interface seat comprises: a carrier board 6, an interface seat 3, a mounting member 1, a chassis panel 5 and a bottom cover 2, wherein one end of the mounting member 1 is connected to the chassis panel 5, and the other end of the mounting member 1 is connected to the bottom cover 2 to form a shielding chamber, the interface seat 3 is installed in the mounting member 1, one end of the carrier board 6 is plugged into the mounting member 1, the first part of the carrier board 6 located outside the shielding chamber has a filter device 11 and a terminal block 10, and the second part of the carrier board 6 located in the shielding chamber forms a conductive overlap with the mounting member 1 and the bottom cover 2 respectively.

[0027] Specifically, the mounting member 1, the bottom cover 2, and the chassis panel 5 in the standard interface seat can be collectively referred to as structural members, and the interface seat 3 is an upright, welded plate type RJ45 interface seat. One end of the mounting member 1 in the structural member is connected to the chassis panel 5, and because the interface seat 3 is installed in the mounting member 1, the interface seat 3 is fastened and installed through the structural member.

[0028] Specifically, the carrier plate 6 is a carrier of the interface seat 3, and the interface seat 3 is welded on the carrier plate 6. Figure 2 As shown, one end of the carrier board 6 is plugged into the mounting member 1 , and the other end of the mounting member 1 and the bottom cover 2 form a shielding chamber, so that the interface seat 3 is installed in the mounting member 1 .

[0029] Specifically, the first part of the carrier board 6 located outside the shielding chamber has a filter device 11 and a terminal block 10, so that the filter device 11 is used to filter the noise of the network signal transmitted from the terminal block 10, thereby reducing the electromagnetic noise and radiation interference of the network signal transmitted into the second part of the carrier board, so that the conductive overlap formed by the second part of the carrier board 6 located in the shielding chamber and the mounting part 1 and the bottom cover 2 respectively meets the electromagnetic shielding requirements.

[0030] The scheme of the present invention is to install the interface seat in the mounting part so that the interface seat is fixed in the structural part, thereby realizing the firm installation of the interface seat through the connection between the mounting part and the chassis panel, that is, through the mounting part belonging to the structural part and the chassis panel, and to perform noise filtering through the filter device and the wiring seat provided in the first part of the carrier board, thereby reducing the electromagnetic noise and radiation interference of the network signal transmitted into the second part of the carrier board, thereby meeting the electromagnetic shielding requirements by forming a conductive overlap with the mounting part and the bottom cover.

[0031] In some embodiments, the second part of the carrier 6 includes: a first copper clad area 7 and a second copper clad area 8, wherein the first copper clad area 7 is located on a side of the second part adjacent to the mounting member 1, forming a conductive overlap with the mounting member 1; the second copper clad area 8 is located on a side of the second part adjacent to the bottom cover 2, forming a conductive overlap with the bottom cover 2.

[0032] Specifically, Figure 1 , Figure 2 As shown, the first copper-clad area 7 is also called the top copper-clad area, located on the side of the second part adjacent to the mounting member 1, and is the area formed after the carrier 6 is coated with copper around the interface seat 3 on the side surface. Similarly, the second copper-clad area 8 is also called the bottom copper-clad area, located on the side of the second part adjacent to the bottom cover 2, and is the area formed after the carrier 6 is coated with copper around the interface seat 3 on the side surface. It should be understood that Figure 2 The left figure in the middle is a schematic diagram of the front structure of the carrier board 6, that is, a schematic diagram of the orthographic projection of the area including the first copper-clad area 7 as the main view. Figure 2 The figure on the right side in the middle is a schematic diagram of the back structure of the carrier board 6, that is, a schematic diagram of the back projection with the area including the second copper clad area 8 as a back view.

[0033] Specifically, since the carrier board 6 is divided into a first part and a second part, and the first part has a filter device 11, the first part of the carrier board 6 is a noise area, and the second part is a pure area. Since the first copper clad area 7 and the second copper clad area 8 are both in the second part, the network signal is converted into a relatively pure network signal after filtering and transmitted to the RJ45 interface socket in the copper clad area, and the pure signal has minimal electromagnetic noise conduction and radiation interference.

[0034] In some embodiments, the second portion of the carrier board 6 further includes: a via 9, the via 9 connecting the first copper clad area 7 and the second copper clad area 8, so that the first copper clad area 7, the second copper clad area 8, the mounting member 1, and the bottom cover 2 form an isolated shielding compartment.

[0035] Specifically, Figure 1 As shown, since the first copper clad area 7 and the second copper clad area 8 are respectively located on both sides of the carrier 6, and the via 9 connects the first copper clad area 7 and the second copper clad area 8, while the mounting member 1 and the bottom cover 2 are respectively conductively overlapped with the first copper clad area 7 and the second copper clad area 8 of the carrier 6, a shielding cavity is formed through the via 9, that is, an isolation shielding compartment is formed.

[0036] In some embodiments, the standard interface seat further includes a conductive rubber strip 4 , which is used to fill the gap between the mounting component 1 and the chassis panel 5 .

[0037] Specifically, the conductive rubber strip 4 used to fill the gap between the mounting member 1 and the chassis panel 5 is to avoid the destruction of the closed overlapping environment due to the existence of the gap, thereby forming a closed conductive overlapping with the mounting member (1) and the bottom cover (2) through the second part, thereby preventing the internal electromagnetic noise of the device from coupling to the network port signal in the form of spatial radiation and radiating to the outside, and also preventing the external electromagnetic noise from entering the device through the gap of the interface seat, thereby ensuring a pure network signal in the pure area.

[0038] In some embodiments, the mounting member 1 has a threaded hole.

[0039] In some embodiments, one end of the mounting member 1 is threadedly connected to the chassis panel 5 through a threaded hole.

[0040] Specifically, since the interface seat 3 is installed in the mounting member 1, one end of the mounting member 1 is threadedly connected to the chassis panel 5 through a threaded hole. Therefore, by installing the interface seat in the mounting member, the interface seat is fixed in the structural member, thereby achieving a firm installation of the interface seat through the connection between the mounting member and the chassis panel, that is, through the mounting member belonging to the structural member and the chassis panel.

[0041] In some embodiments, the mounting member 1 has a snap-fit.

[0042] In some embodiments, one end of the mounting member 1 is snap-connected to the chassis panel 5 via a snap-on connection.

[0043] Specifically, since the interface seat 3 is installed in the mounting member 1, one end of the mounting member 1 is snap-connected to the chassis panel 5 via a screw clip. Therefore, by installing the interface seat in the mounting member, the interface seat is fixed in the structural member, thereby achieving a firm installation of the interface seat through the connection between the mounting member and the chassis panel, that is, through the mounting member belonging to the structural member and the chassis panel.

[0044] In some embodiments, the filter device 11 is an EMI filter device.

[0045] In some embodiments, an EMI filter device includes a common-mode inductor, where the common-mode inductor is used to suppress electromagnetic radiation.

[0046] Specifically, the EMI filter device is composed of an EMI filter circuit, which mainly includes power supply, ground filtering and network signal common mode filtering. Common mode interference is the main cause of signal electromagnetic radiation. This embodiment uses common mode inductors to perform common mode filtering on each group of network differential signals, reduce common mode current, and suppress electromagnetic radiation. Common mode inductors, also known as common mode chokes, are electronic components used to filter common mode electromagnetic interference signals. They are usually composed of two coils of the same size and the same number of turns symmetrically wound on the same ferrite toroidal core to form a four-terminal device. When a common mode current flows through the coil, due to the isotropic nature of the common mode current, a magnetic field of the same direction will be generated in the coil, increasing the inductive reactance of the coil, making the coil appear as high impedance, and producing a strong damping effect, thereby attenuating the common mode current. Thereby, the carrier board 6 is divided into: the first part is the noise area, and the second part is the pure area. Since the first copper clad area 7 and the second copper clad area 8 are both in the second part, the network signal is converted into a relatively pure network signal after filtering and transmitted to the RJ45 interface socket in the copper clad area, and the pure signal electromagnetic noise conduction and radiation interference are minimal.
