[0045] Hereinafter, embodiments of the present invention will be described in detail with reference to the relevant drawings.

[0046]

[0047] FIG. 1 is a drawing illustrating a connector according to one embodiment of the present invention.

[0048] Referring to FIG. 1, a connector according to one embodiment may include a receptacle connector (100) and a plug connector (200). The receptacle connector (100) may correspond to a female connector, and the plug connector (200) may correspond to a male connector. The receptacle connector (100) and the plug connector (200) may be electrically and mechanically connected and separated from each other.

[0049]

[0050] The receptacle connector (100) can be directly connected to a board (10). The plug connector (200) can be directly connected to another board (20). That is, the receptacle connector (100) and the plug connector (200) are electrically connected to and mounted on corresponding boards (10, 20), respectively, and then function as board-to-board connectors that are electrically and mechanically connected or separated from each other.

[0051]

[0052] FIG. 2 is a drawing showing a state in which a plug connector (200) is connected to a receptacle connector (100) of the connector shown in FIG. 1.

[0053] Referring to FIG. 2, a plug connector (200) can be connected to a receptacle connector (100). When the plug connector (200) is connected to the receptacle connector (100), the substrate (10) and the substrate (20) are electrically connected to exchange power and data.

[0054]

[0055] Fig. 3 is a drawing illustrating a receptacle connector (100). Hereinafter, in the drawing, the x-axis represents the width direction of the connector and may represent the row direction. The y-axis may represent the length direction of the connector. The z-axis represents the up-down direction of the connector and may represent the column direction.

[0056]

[0057] Referring to FIG. 3, the receptacle connector (100) may include a plurality of receptacle sockets (110) and a receptacle connector body (120).

[0058] The receptacle connector body (120) may include a protrusion (121) that protrudes along the longitudinal direction (y). The protrusion (121) is a portion that is inserted into the interior of the plug connector (200). All receptacle sockets (110) may be located on the inside of the protrusion (121). In addition, the receptacle connector (100) may include a guide protrusion (122). The guide protrusion (122) may protrude from the side of the protrusion (121). The guide protrusion (122) may be formed to be long along the longitudinal direction (y). The guide protrusion (122) may be located at the center of the protrusion (121) in the width direction (x).

[0059]

[0060] A plurality of receptacle sockets (110) can be coupled to a receptacle connector body (120). The plurality of receptacle sockets (110) can be arranged along rows and columns. The plurality of receptacle sockets (110) can be divided into a receptacle socket (111) that transmits power and a receptacle socket (112) that transmits data. A plurality of receptacle sockets (111) that transmit power can be arranged. And a plurality of receptacle sockets (112) that transmit data can also be arranged. An area where a plurality of receptacle sockets (111) that transmit power are located and an area where a plurality of receptacle sockets (112) that transmit data are located can be distinguished.

[0061] Since the position of this receptacle socket (110) corresponds to the plug pin (210) of the plug connector (200), the position of the plug pin (210) is described with reference to the drawing below.

[0062]

[0063] Fig. 4 is a perspective view illustrating a plug connector (200), and Fig. 5 is a front view of the plug connector (200) illustrated in Fig. 4.

[0064] Referring to FIGS. 4 and 5, the plug connector (200) may include a plurality of plug pins (210) and a plug connector body (220).

[0065] The plug connector body (220) may include a groove (221). The guide protrusion (122) of the receptacle connector (100) may be inserted into the groove (221). When the plug connector (200) is inserted into the receptacle connector (100), the guide protrusion (122) may guide the plug connector (200) by being inserted into the groove (221). In addition, when the plug connector (200) is connected to the receptacle connector (100), the guide protrusion (122) may serve to fix the plug connector (200) so that the plug connector (200) does not move. This groove (221) may be located at the center of the width direction (x) of the plug connector (200). The position of the home portion (221) may correspond to the position of the guide protrusion (122) of the receptacle connector (100).

[0066] A plurality of plug pins (210) can be coupled to a plug connector body (220).

[0067] A plurality of plug pins (210) may be arranged along rows and columns. The plurality of plug pins (210) may be divided into plug pins (211) that transmit power and plug pins (212) that transmit data. A plurality of plug pins (211) that transmit power may be arranged. And a plurality of plug pins (212) that transmit data may also be arranged. The area where the plurality of plug pins (211) that transmit power are located and the area where the plurality of plug pins (212) that transmit data are located may be distinguished.

[0068] Specifically, the plug connector (200) may include a first area (A1) in which plug pins (211) for transmitting power are arranged and a second area (A2) in which plug pins (212) for transmitting data are arranged. Here, the first area (A1) may refer to an internal space of the plug connector body (220) bordering the plug pins (211) located at the outermost side among the plug pins (211) for transmitting power. And the second area (A2) may refer to an internal space of the plug connector body (220) bordering the plug pins (212) located at the outermost side among the plug pins (212) for transmitting data.

[0069] The connector according to the embodiment aims to reduce the size and spacing of the plug pins (210) and to arrange the plug pins (210) at a high density, thereby reducing the size and weight of the connector.

[0070] Hereinafter, with reference to the drawings, the arrangement of plug pins (210) to reduce the size and weight of the connector and the corresponding size and spacing will be described.

[0071]

[0072] Figure 6 is a drawing showing plug pins (211) that transmit power.

[0073] Referring to FIGS. 5 and 6, in the plug pins (211) that transmit power, in the first region (A1), the distance (S1) between the plug pins (211) based on the row may be smaller than the outer diameter (D1) of the plug pins (211). In addition, the distance (S2) between the plug pins (211) based on the column may be smaller than the outer diameter (D1) of the plug pins (211). The distance (S1) between the plug pins (211) based on the row may be the same as the distance (S2) between the plug pins (211) based on the column. The outer diameters (D1) of the plug pins (211) arranged in the first region (A1) may all be the same.

[0074] In this first area (A1), four plug pins (210) can be arranged. However, this is not limited thereto.

[0075]

[0076] Figure 7 is a drawing showing plug pins (212) that transmit data.

[0077] Referring to FIGS. 5 and 7, the plug pins (212) for transmitting data, in the second area (A2), the distance S3 between the plug pins (212) based on the row may be smaller than the outer diameter (D2) of the plug pins (212). And, the distance S4 between the plug pins (212) based on the column may be smaller than the outer diameter (D2) of the plug pins (212). The distance S3 between the plug pins (212) based on the row may be the same as the distance S4 between the plug pins (212) based on the column. The outer diameters (D2) of the plug pins (212) arranged in the second area (A2) may all be the same.

[0078] The outer diameter (D2) of the plug pins (210) can be minimized so that these plug pins (210) can be arranged at a high density. For example, the pitch (P1) of the plug pins (210) based on the row can correspond to 1.27 mm. And the pitch (P2) of the plug pins (210) based on the column can correspond to 1.27 mm. However, it is obvious that this pitch can be determined in various ways by the designer according to the design specifications.

[0079] Meanwhile, since the plug pin (212) that transmits data has a small outer diameter (D2), only two cuts can be formed, and by arranging the two cuts in a straight line, deformation of the plug pin (212) can be minimized when manufacturing the plug pin (212).

[0080]

[0081] Figure 8 is a drawing showing a plug pin (211) that transmits power and a plug pin (212) that transmits data.

[0082] Referring to FIGS. 5 and 8, the spacing distance (S3) between plug pins (212) based on rows in the second region (A2) may be smaller than the spacing distance (S1) between plug pins (211) based on rows in the first region (A1). In addition, the spacing distance (S4) between plug pins (212) based on columns in the second region (A2) may be smaller than the spacing distance (S2) between plug pins (211) based on columns in the first region (A1).

[0083]

[0084] Figure 9 is a drawing showing the receiving portion (AP) of the plug connector (200).

[0085] Referring to FIG. 9, the plug connector body (220) of the plug connector (200) may include a receiving portion (AP) that forms a space into which the protrusion (121) of the receptacle connector (100) is inserted. A plug pin (211) for transmitting power and a plug pin (212) for transmitting data may be located inside the receiving portion (AP).

[0086] The receiving portion (AP) may include a central portion (AP1) positioned in the center with respect to the width direction (x), a first side portion (AP2) positioned on one side of the central portion (AP1), and a second side portion (AP3) positioned on the other side of the central portion (AP1).

[0087] Here, the vertical length (H2) of the first side (AP2) and the vertical length (H3) of the second side (AP3) may be greater than the vertical length (H3) of the central part (AP1). That is, the central part (AP1) may be relatively narrow in the vertical direction (z), and the first side (AP2) and the second side (AP3) may be relatively wider than the central part (AP1) in the vertical direction (z).

[0088] The central portion (AP1) can be connected to the home portion (221).

[0089] Here, the first region (A1) may be located on the first side (AP2). The second region (A2) may be arranged across the central region (AP1) and the second side (AP3).

[0090]

[0091] Figure 10 is a drawing showing a plating layer (110a, 210a) formed on a plug pin (210) and a receptacle socket (110).

[0092] Referring to FIG. 10, the plug pin (210) and the receptacle socket (110) may each include plating layers (110a, 210a). The plating layer (210a) of the plug pin (210) may be in contact with the plating layer (110a) of the receptacle socket (110). By virtue of this plating layer, impedance matching may be improved when the plug pin (210) and the receptacle socket (110) are coupled, and data and power transmission errors may be reduced.
