Detailed Description
Fig. 1 is a schematic view of a connector according to an embodiment of the present invention. Referring to fig. 1, a connector 100 of the present embodiment is, for example, a female connector disposed on a circuit board. Specifically, the connector 100 of the present embodiment is, for example, a connector applied to a server, and supports Gen 4/Gen 5/Gen6/Gen Z. Of course, the kind of the connector 100 of the present embodiment is not limited thereto.
The connector 100 of the present embodiment includes a plurality of power signal pins 110 and a plurality of high-speed signal pins 120. The power signal pins 110 are arranged in a first pin area 102. The high-speed signal pins 120 are arranged in a second pin field 104. The first pin area 102 is located beside the second pin area 104.
As can be seen from fig. 1, the width W1 of each power signal pin 110 is greater than the width W2 of each high-speed signal pin 120. The width W1 is, for example, 2 to 5 times the width W2, but the relationship between the widths W1 and W2 is not limited thereto.
In addition, the distance D1 between two adjacent power signal pins 110 is greater than the distance D2 between two adjacent high-speed signal pins 120. For example, the distance D1 between two adjacent power signal pins 110 is between 2 mm and 3 mm, such as 2.54 mm. The distance D2 between two adjacent high-speed signal pins 120 is between 0.4 mm and 0.8 mm, for example, 0.5 mm. Of course, the distances D1, D2 are not limited thereto.
In the present embodiment, the connector 100 integrates the power connector 100 and the high-speed signal connector 100, so as to achieve the effects of simplifying components, saving space and reducing cost. In addition, in the present embodiment, the distance D2 between two adjacent high-speed signal pins 120 is smaller than the known distance, so that space can be saved.
In addition, the width of the power signal pins 110 is greater than the width of the high-speed signal pins 120, and the distance between two adjacent power signal pins 110 is greater than the distance between two adjacent power signal pins 120, so that the power signal pins 110 can stably transmit electrical signals, and the high-speed signal pins 120 can be densely arranged.
It should be noted that the numbers of the high-speed signal pins 120 and the power signal pins 110 in fig. 1 are only illustrative. For example, the power signal pins 110 shown at present can transmit 6 amperes of current, and if 24 amperes are to be supported, four groups of the power signal pins 110 shown at present can be provided. In addition, the high-speed signal pins 120 may be increased or decreased, for example, 148 pins are the highest-sized high-speed signal pins 120 in the case of Gen 5, and the designer may increase or decrease the number of pins according to the needs.
It should be noted that, in order to improve the isolation between the high-speed signal and the power signal and avoid signal interference, the connector 100 of the present embodiment further has a special design, which will be described below.
Fig. 2 is a perspective cross-sectional view of another view along line A-A of fig. 1. Fig. 3 is a perspective sectional view taken along line B-B of fig. 1. Fig. 4 is a schematic view of the connector of fig. 1 with the insulation hidden. Fig. 5 is a perspective cross-sectional view of fig. 4 along line C-C.
Referring to fig. 2 to 5, the connector 100 further includes a first shielding plate 132 (fig. 4) disposed between the first pin area 102 and the second pin area 104 to separate the power signal pins 110 from the high-speed signal pins 120. In addition, as shown in fig. 4, in the present embodiment, the connector 100 further includes a plurality of second shielding plates 134, which are connected to each other and the first shielding plates 132 in a bending manner, wherein the first shielding plates 132 and the second shielding plates 134 together form a shielding housing 130 surrounding the high-speed signal pins 120, and the shielding housing 130 may be made of metal (e.g., iron).
That is, the shielding housing 130 surrounds the high-speed signal pins 120 to prevent the high-speed signal from being interfered by the external or power signal. In detail, the shielding case 130 can shield the inductance caused by the power during the transmission process, and eliminate electromagnetic interference (EMI). In addition, the shielding case 130 may be grounded, for example, to a ground plane of a motherboard (not shown), to guide noise to ground, so as to provide a better shielding effect.
It should be noted that, as shown in fig. 3 and 5, the connector 100 further includes an inner shielding plate 140, the inner shielding plate 140 may be made of metal (e.g. iron), the high-speed signal pins 120 are arranged in two rows, and the inner shielding plate 140 is disposed between the two rows of high-speed signal pins 120 to reduce interference between the two rows of high-speed signal pins 120, so as to reduce far-end crosstalk and near-end crosstalk. The inner shielding sheet 140 may also be grounded, for example, to a ground plane of a motherboard (not shown), to guide noise to ground, to provide a better shielding effect.
In addition, as shown in fig. 1 and 3, in the present embodiment, the connector 100 further includes an insulating member 150 covering a portion of each of the power signal pins 110, a portion of each of the high-speed signal pins 120, at least a portion of the shielding shell 130, and at least a portion of the inner shielding plate 140, so as to make assembly more stable and facilitate signal transmission.
The insulating member 150 is used to protect the power signal pins 110, the high-speed signal pins 120, the shielding case 130, and the inner shielding plate 140. Since the dielectric constant of air is 1, the insulating member 150 is made of a material having a dielectric constant greater than 1, so that crosstalk interference can be reduced.
For example, the material of the insulator 150 includes a LIQUID CRYSTAL POLYMER (LCP) having a dielectric constant of 3.6, which is greater than that of air. Of course, the material and the dielectric constant of the insulating member 150 are not limited thereto.
The distance D2 between two adjacent high-speed signal pins 120 of the connector 100 of the present embodiment is, for example, 0.5 mm, which can meet the PCI-E specification. In addition, the connector 100 of the present embodiment may conform to the PCI-EGen 5 transmission specification (32G). In addition, the characteristic impedance of the connector 100 of the present embodiment can satisfy 82 ohms, the insertion loss can satisfy-1.5 dB, the reflection loss can satisfy-10 dB, the crosstalk can satisfy-40 dB, and the current resistance of 8 amperes can be considered, and the specification of PCI-E can be satisfied, thereby having good performance.

The first pin area 102 is located beside the second pin area 104.
The first shielding plate 132 is disposed between the first pin area 102 and the second pin area 104 to separate the power signal pins 110 from the high-speed signal pins 120. In addition, in the present embodiment, the first shielding plates 132 and the second shielding plates 134 together form a shielding housing 130 surrounding the high-speed signal pins 120. The inner shielding plate 140 is disposed between the two rows of high-speed signal pins 120 to reduce interference between the two rows of high-speed signal pins 120.
The insulating member 150 covers a portion of each power signal pin 110, a portion of each high-speed signal pin 120, at least a portion of the shielding shell 130, and at least a portion of the inner shielding plate 140 to protect the power signal pins 110, the high-speed signal pins 120, the shielding shell 130, and the inner shielding plate 140.

Referring to fig. 9 to 10, the connector 200a of the present embodiment is, for example, a male connector disposed on a circuit board, and is capable of being connected to the slot of the female connector 100 of fig. 2.
Similarly, in the present embodiment, the connector 200a includes a plurality of power signal pins 110 and a plurality of high-speed signal pins 120.

The first pin area 102 is located beside the second pin area 104.
The first shielding plate 132 is disposed between the first pin area 102 and the second pin area 104 to separate the power signal pins 110 from the high-speed signal pins 120. In addition, in the present embodiment, the first shielding plates 132 and the second shielding plates 134 together form a shielding housing 130 surrounding the high-speed signal pins 120.

In summary, the power signal pins of the connector of the present invention are arranged into a first pin area. The high-speed signal pins are arranged into a second pin area, and the first pin area is positioned beside the second pin area.
