[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows a three-dimensional schematic diagram of the board-to-board plug connector of this utility model, a three-dimensional exploded schematic diagram of the board-to-board plug connector, a cross-sectional structural schematic diagram of the board-to-board plug connector, and a cross-sectional structural separation schematic diagram of the board-to-board plug connector and the board-to-board socket connector.

[0021] This utility model relates to a board-to-board plug connector, a board-to-board socket connector for power supply connection. The board-to-board plug connector 1 mainly includes: a body 10, a plurality of plug terminals 12, and a metal frame 14. The body 10 has two correspondingly arranged long sidewalls 100, and a receiving groove 101 is defined between each long sidewall 100. Mounting structures 102 are respectively provided at both ends of each long sidewall 100. Each mounting structure 102 and each long sidewall 100 respectively define a side clearance area 103. The mounting structure 102 forms at least one positioning slot 104. Each plug terminal 12 is correspondingly disposed on each long side wall 100. The metal frame 14 defines two long side frames 140 and two short side frames 142 that are respectively connected to the two ends of each long side frame 140. During installation, each short side frame 142 is provided with at least one positioning element 144. Each short side frame 142 is disposed on the mounting structure 102 and is inserted into the positioning slot 104 by the positioning element 144.
