Embodiment 1
[0028] see image 3 , which is a structural diagram of the first embodiment of the pinch board connector shielding device according to the embodiment of the present invention.
[0029] The pinch board connector shielding device provided in this embodiment includes: a cavity composed of vertical plates with upper and lower openings, used for shielding signal interference between the first PCB board 101 and the second PCB board 102 .
[0030] Inside the cavity is a shielding rib 302 composed of at least one vertical plate. The shielding ribs 302 divide the cavity into at least two regions, and are used to shield signals from devices in each region from interfering with each other.
[0031] like image 3 As shown, there is only one shielding rib 302 in the cavity, which is used to shield the first group of devices 204a in the first area and the second group of devices 204b in the second area, so as to avoid signal interference between the devices in the two areas .

Embodiment 2
[0041] see Figure 4 , which is a perspective view of a pinch board connector shielding device according to an embodiment of the present invention.
[0042] The cavity 301 of the shielding device provided in this embodiment is a circumferential closed space with a first opening 404a above and a second opening 404b below. The first opening 404a places the first PCB board; the second opening 404b places the second PCB board 102 .
[0043] It should be noted that, the plane where the first opening 404a and the second opening 404b of the cavity 301 are located are respectively provided with a first shielding material and a second shielding material (not shown in the figure).
[0044] The components on the first PCB are located above the first shielding material; the components on the second PCB are located above the second shielding material.
[0045] It should be noted that the first PCB board is clamped on the inner wall of the first opening 404a or located above the first ope...
Embodiment 3
[0064] see Figure 8 , which is a structural diagram of the third embodiment of the pinch board connector shielding device according to the embodiment of the present invention.
[0065] There are two flanges 401 on one side of the cavity 301 of the shielding device provided in this embodiment, and there are four flanges 401 in total on the left and right sides.
[0066] There are screw holes on the flange edge 401 . The screws 801 fix the first PCB board and the second PCB board together with the shielding device through the screw holes.
[0067] In addition, it can be seen from the figure that the gaps between devices are filled with shielding material 303 to avoid interference of signals through the gaps.

Abstract
The invention provides a shielding device of gusset plate connector. The shielding device is a cavity with an upper opening and a lower opening. The cavity therein is provided with at least one shielding separation rib that separates the cavity into at least two regions used for shielding the signal interference between the signal connectors in each region. The upper opening of the cavity is usedfor putting a first PCB plate and the lower opening is used for putting a second PCB plate. The shielding device of gusset plate connector is capable of completely separating the elements on two PCB plates by the PCB plates and the shielding device, so as to shield the signals between two PCB plates. The cavity therein is provided with the separation rib, and the number of the separation ribs canbe 1 or 2 according to conditions so as to separate the cavity into at least two regions, and the signals in each region and other regions are electrically separated. The shielding device provided inthe embodiment of the invention can not only shield the signals between the PCB plates, also shield the signals among the PCB plates and the signal connectors and among the signal connectors.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a pinch board connector shielding device. Background technique [0002] In the PCB stack-up layout, a signal connector is required when a signal connection is required between the PCB board and the PCB board. General signal connectors do not have their own shielding structure. In order to prevent crosstalk between PCB boards, between PCB boards and signal connectors, and between signal connectors, shielding between signals is required. [0003] see figure 1 , which is a connection structure diagram of two PCB boards. [0004] Signal connections are made between the first PCB board 101 and the second PCB board 102 through a signal connector A103 and a signal connector B104. Among them, the signal connector A103 carries the power signal, and the signal connector B104 carries the high-speed signal. The strong electric radiation generated by the current in the signa...
