[0026] like Figure 1As shown, the double-row connector 2 includes two rows of pads arranged at intervals, namely, a first row of pads 20 and a second row of pads 21. In this embodiment, the first row of pads 20 and the second row of pads 21 are arranged side by side along the tin furnace passing direction 3. At least one row of pads in the first row of pads 20 and the second row of pads 21 are arranged at intervals with a plurality of first common pads 200 and tin-drag pads 201. In some feasible embodiments, the first row of pads 20 and the second row of pads 21 are arranged at intervals with a plurality of first common pads 200 and tin-drag pads 201. In some other feasible embodiments, the first row of pads 20 are arranged with common pads 210 at intervals, and the second row of pads 21 are arranged with a plurality of first common pads 200 and tin-drag pads 201 at intervals.
[0027] In this embodiment, a plurality of first common pads 200 and tinning pads 201 are arranged at intervals in the first pad row 20, and the tinning pad 201 is arranged between every two first common pads 200. Common pads 210 are arranged at intervals in the second pad row 21.
[0028] The two pads of the first row of pads 200 of the double-row connector 2, which are close to the tinning furnace and far away from the tinning furnace, are first common pads 200. A plurality of first common pads 200 are arranged between the first common pads 200 at both ends, and each two first common pads 200 are separated by a tinning pad 201. A spacing is arranged between the first common pads 200 and the tinning pads 201. The spacing between the tinning pads 201 and the first common pads 200 is the same. The position and quantity of the first common pads 200 and the tinning pads 201 are merely examples, and are not limited here, and can be arranged according to actual needs.
[0029] like Figure 2 As shown, the tinning pad 201 includes a base 2010 and tinning portions 2011 extending from the middle of the base 2010 on both sides in a direction 3 relative to the tinning furnace. The length B of the tinning portion 2011 is between 1 and 1.5 times the width A of the first common pad 200, and the width C of the tinning portion 2011 is the same as the width A of the first common pad 200. The first common pad 200 is the same as the common pad 210. For example, the width A of the first common pad 210 is 0.5 mm, the width C of the tinning pad 201 is also 0.5 mm, and the length B of the tinning pad 201 is between 0.5 mm and 1.5 mm (including 0.5 mm and 1.5 mm).
[0030] Specifically, the base 2010 of the tinning pad 201 is a circular ring, and the tinning portion 2011 is tightly connected to the base 2010, that is, there is no gap. The length B of the tinning pad 201 is from the center of the base 2010 to the bottom of the tinning portion 2011, and the width C of the tinning pad 201 is the diameter of the outer circle of the base 2010. When passing through the tin furnace, the tinning pad absorbs the excess tin of the nearby pads through the mutual traction of the tin, thereby achieving the effect of avoiding tinning. Among them, the side of the tinning portion 201 close to the base 2010 is arc-shaped, and the side away from the base 2010 is rectangular.
[0031] The second row of pads 21 is arranged on one side of the first row of pads 20 along the direction 3 of passing through the tin furnace. The second row of pads 21 includes ordinary pads 210 arranged at intervals. The center of the base 2010 is located on the same straight line as the center of the first ordinary pad 200. The straight line is perpendicular to the direction 3 of passing through the tin furnace. Specifically, a spacing is provided between each ordinary pad 210, and each spacing is equal. In this embodiment, the center of the ordinary pad 210 of the second row of pads 21 is symmetrical with the center of the first ordinary pad 200 of the first row of pads 200 and the tinning pad 210. The ordinary pad 210 is a circular ring, and the width of the ordinary pad 210 is the diameter of the outer circle of the circular ring.
[0032] like Figure 3 As shown, an embodiment of the present application provides a schematic structural diagram of a device with a double-row connector.
[0033] The device with a double-row connector includes a PCB board 1 and a double-row connector 2 connected to the PCB board 1. A plurality of double-row connectors 2 are arranged at intervals on the device with a double-row connector. The device with a double-row connector includes but is not limited to electronic devices (computers, mobile phones, etc.) and communication devices (routers, switches, etc.). The double-row connector 2 has been described in detail and will not be repeated here.
