Description

Technical field

[0001] The present invention relates to the technical field of connectors, in particular to a high-frequency grounding terminal structure and a card edge connector. [Background Technology]

[0002] Traditional connectors are used in low-frequency and low-speed environments. However, with the demand for high-frequency and high-speed applications, ensuring that connectors operate in high-frequency environments requires not only a robust structure but also the ability to maintain high-frequency signal transmission quality, accuracy, and stability.

[0003] In view of this, the present invention proposes a high-frequency grounding terminal structure and a card edge connector that can operate in a high-frequency, high-speed, and low-crosstalk environment. [Summary of the invention]

[0004] A first object of the present invention is to provide a card edge connector capable of connecting a first printed circuit board and a second printed circuit board.

[0005] A second object of the present invention is to provide an electrode sheet having a body, a clamp, a pin, a first contact point, and a second contact point based on the above-mentioned card edge connector, so as to connect the ground of the first printed circuit board and the second printed circuit board, wherein the first contact point is defined at a side edge of the body and is adjacent to the pin, and the second contact point is defined at the body between the two clamps.

[0006] A third object of the present invention is that, based on the aforementioned card edge connector, the electrode sheet can be further combined with the first grounding sheet to electrically connect to the first contact point, thereby expanding the grounding area.

[0007] A fourth object of the present invention is that, based on the aforementioned card edge connector, the electrode sheet can be further combined with a second grounding sheet to electrically connect to the second contact point, thereby expanding the grounding area.

[0008] A fifth objective of the present invention is to optimize high frequency performance and alleviate crosstalk issues by forming a ground loop through the first grounding plate and the second grounding plate in the aforementioned card edge connector.

[0009] A sixth object of the present invention is to provide a high-frequency grounding terminal structure to optimize high-frequency performance and improve crosstalk issues.

[0010] To achieve the above-mentioned and other purposes, the present invention provides a card edge connector capable of connecting a first printed circuit board and a second printed circuit board. The first printed circuit board and the second printed circuit board respectively provide a power supply, a ground, and a signal. The card edge connector includes a power supply unit and a signal unit. The power supply unit can connect the power supply and the ground of the first printed circuit board and the second printed circuit board respectively. The signal unit includes a plurality of electrode sheets, a plurality of signal terminals, and a plurality of insulating members. The plurality of signal terminals are between two adjacent electrode sheets. The plurality of signal terminals can receive signals from the second printed circuit board. The plurality of insulating members fix the plurality of signal terminals between two adjacent electrode sheets. Each electrode sheet further includes a body, a clamp, a pin, a first contact point, and a second contact point. The body is electrically connected to the clamp, the pin, the first contact point, and the second contact point. The clamp is connected to the ground of the second printed circuit board, and the pin is connected to the ground of the first printed circuit board.

[0011] To achieve the above-mentioned and other purposes, the present invention provides a high-frequency grounding terminal structure, which is applied to a first printed circuit board and a second printed circuit board. The first printed circuit board and the second printed circuit board respectively provide a power supply, a ground and a signal. The high-frequency grounding terminal structure includes a main body, a plurality of clips, a pin, a first contact point and a second contact point. The plurality of clips extend from the main body in a first direction so as to clamp the second printed circuit board and thereby receive the signal from the second printed circuit board. The pin extends from the main body in a second direction to connect to the ground or power supply of the first printed circuit board. The first contact point is defined at the side edge of the main body and is adjacent to the pin. The second contact point is defined in the main body between the plurality of clips.

[0012] Compared to traditional connectors, the high-frequency grounding terminal structure proposed in the present invention can achieve the advantages of high frequency and high-speed transmission by providing a large-area body, clamps and pins. In another embodiment, the body can also selectively overlap the body through the first ground plate and / or the second ground plate to form a ground loop, thereby optimizing high-frequency performance and improving crosstalk / crosstalk problems. That is, it solves the problem of unnecessary inductive and capacitive coupling between the two signal lines due to the close spatial distance between the two signal lines, thereby causing signal interference.

Figure 1 In the embodiment, the card edge connector 10 is capable of connecting a first printed circuit board 2 and a second printed circuit board 4. The first printed circuit board 2 and the second printed circuit board 4 respectively provide a power supply (not shown), a ground (not shown), and a signal (not shown). In this embodiment, the power supply, ground, and signal may refer to pads, solder pads, etc. used to transmit power, ground, and signals between the first printed circuit board 2 and the second printed circuit board 4, or may refer to power, voltage, ground, etc.

[0041] For reference Figure 2 , is to illustrate the present invention Figure 1 Schematic diagram of the card edge connector. Figure 2 In the embodiment, the card edge connector 10 includes a power supply unit A and a signal unit B. The number of power supply units A is two, and the number of signal units B is five. The two power supply units A are respectively arranged on the two sides of the signal unit B. The following description is based on one of them. The description and functions of the other identical components are the same. It is worth noting that in another embodiment, the card edge connector 10 can also be similar to Figure 1 The power supply part A and the signal part B can be covered by the shell 14.

[0042] The power supply unit A can be connected to the power supply and the ground of the first printed circuit board 2 and the second printed circuit board 4 respectively.

[0043] The signal portion B includes an electrode sheet 122 , a signal terminal 124 and an insulating member 126 .

[0044] For reference Figure 3 , is to illustrate the present invention Figure 2 Detailed structural diagram of the electrode sheet. Figure 3In the embodiment, the electrode sheet 122 includes a body 1222, a clamp 1224, a pin 1226, a first contact point 1228, and a second contact point 12210. It should be noted that the electrode sheet 122 may also be referred to as a high-frequency grounding terminal structure in the present invention.

[0045] The body 1222 is electrically connected to the clip 1224 , the pin 1226 , the first contact point 1228 , and the second contact point 12210 .

[0046] The clamp 1224 holds the ground of the second PCB 4 and the pin 1226 connected to the ground of the first PCB 2. The clamp 1224 and the pin 1226 pass through the body 1222 therebetween, so that the ground of the second PCB 4 is electrically connected to the ground of the first PCB 2.

[0047] For reference Figure 4 , is to illustrate the present invention Figure 3 Another embodiment of the electrode sheet. Figure 4 In the embodiment, a plurality of electrode sheets 122 are used as an example, and the structure of each electrode sheet 122 is the same, and they are arranged in parallel, for example. Figure 4 In addition to the original electrode sheet 122, the first grounding sheet 128 and the second grounding sheet 1210 are also included. In this embodiment, although the first grounding sheet 128 and the second grounding sheet 1210 are shown together, in other embodiments, in addition to the original independent electrode sheet 122, the electrode sheet 122 may be combined with the first grounding sheet 128 or the second grounding sheet 1210.

[0048] The first grounding plate 128 is disposed on two side portions of the main body 1222 and can be fixed by the insulating member 126. For example, the first grounding plate 128 can be formed into a pin plug (not shown) with a barbed edge that is inserted into a socket (not shown) formed by the insulating member 126 to fix the first grounding plate 128 on the side of the insulating member 126. In addition to allowing the first grounding plate 128 to insulate the electrode plate 122 through the insulating member 126, the first grounding plate 12 can also be electrically connected to the main body 1222 through the first contact point 1228, allowing the first grounding plate 128 to connect to the pin 1226 through the main body 1222, and then connect to the ground of the first printed circuit 2 through the pin 1226.

[0049] The second grounding plate 1210 is disposed in the center of the body 1222. The body 1222 has a notch formed at the first contact point for accommodating the second grounding plate 1210. This notch allows the second grounding plate 1210 to be electrically connected to the body 1222. This allows the second grounding plate 1210 to connect to the pin 1226 through the body 1222, and further connect to the ground of the first printed circuit 2 through the pin 1226. In another embodiment, the second grounding plate 1210 may further have a slit 12102 formed therein to correspond to the notch (i.e., the location indicated by the second contact point 12210).
