Description

Board to Board Plug Connectors

This creation is a plug connector, in particular a board-to-board plug connector.

According to the standard, board-to-board connectors are used to connect different circuit boards. They have socket connectors and plug connectors that are installed on different circuit boards to connect the circuit boards to each other. In mobile devices such as smartphones, the size of board-to-board connector components is very small, which reduces the structural strength and life of each connector.

Please refer to Figures 1, 2 and 3, which are a three-dimensional schematic diagram of the known board-to-board plug connector, a side view schematic diagram of the known board-to-board plug connector welded on a circuit board, and a front view schematic diagram of the known board-to-board plug connector welded on a circuit board. As can be seen from the figure, the metal parts 10 at both ends of the existing board-to-board plug connector 1 are located at the lower edge 100 of the metal part 10, and the position corresponding to the short side of the board-to-board plug connector 1 is only located at half the height of the board-to-board plug connector 1. In other words, when the board-to-board plug connector 1 is welded to the surface of the circuit board 2, the lower edge 100 of the metal part 10 will not contact the circuit board 2. Therefore, the metal parts 10 at both ends of the board-to-board plug connector 1 are insufficient in structural strength when plugged into the board-to-board socket connector.

Furthermore, not only does the above-mentioned metal part 10 reduce the structural strength of the board-to-board plug connector 1, but it also affects the plugging and unplugging of the male end (plug) and the female end (socket), that is, the strength of some structures is reduced or the terminal elasticity is reduced, resulting in damage caused by structural interference during the process of pulling the male end and the female end apart from each other. In addition, in some usage environments, in order to facilitate charging or information transmission, the electronic module in the device has a large current transmission requirement, which will also increase the manufacturing specifications of the board-to-board connector.

Therefore, how to improve the structural strength of the board-to-board plug connector while making it meet the relevant specifications under large current transmission is indeed a problem that relevant technical personnel need to think about and solve.

The main purpose of this invention is to define a first side wall corresponding to and covering the short side wall of the main body by a metal part and two second side walls respectively extending from the first side wall and covering parts of each long side wall on the main body, wherein the first side wall and each second side wall extend to the circuit board and are surface mounted on the circuit board by SMT, thereby strengthening the structural strength of the board-to-board plug connector after being welded to the circuit board.

To achieve the above-mentioned purpose, the present invention is a board-to-board plug connector, which is soldered on a circuit board surface by surface mount technology (SMT), and includes: A main body has two corresponding long side walls, a corresponding short side wall connected to each of the long side walls, and a receiving groove surrounded and defined by each of the long side walls and each of the short side walls; a plurality of terminals formed on each of the long side walls; and two metal parts respectively arranged at two opposite ends of the main body, wherein the metal parts define a first side wall corresponding to and covering the short side walls and two second side walls respectively extending from the first side wall and covering parts of each of the long side walls, wherein the first side wall and each of the second side walls extend to the circuit board and surface mounting technology (SMT) is applied to the circuit board.

According to an embodiment of the present invention, the first side wall defines a first soldering pin soldered to the circuit board.

According to an embodiment of the present invention, each of the second side walls defines a second soldering foot that is soldered to the circuit board.

The present invention is a board-to-board plug connector. The board-to-board plug connector 3 is welded on the surface of a circuit board 4 using surface mount technology (SMT). The board-to-board plug connector 3 mainly includes: The main body 30, a plurality of terminals 32 and two metal parts 34, wherein the main body 30 has two correspondingly arranged long side walls 300, a correspondingly arranged short side wall 302 connected to each long side wall 300 and a receiving groove 304 surrounded and defined by each long side wall 300 and each short side wall 302, each terminal 32 is formed correspondingly on each long side wall 300, and each metal part 34 is respectively arranged at two opposite ends of the main body 30, wherein the metal part 34 defines a first side wall 340 and a second side wall 342, The first side wall 340 corresponds to and covers the short side wall 302, and the first side wall 340 is bent and extended to have second side walls 342 on both sides, and each second side wall 342 covers a portion of each long side wall 300, wherein the first side wall 340 and each second side wall 342 extend to the circuit board 4 and are surface mounted on the circuit board 4 by SMT, and the first side wall 340 defines a first solder pin 3400 for soldering to the circuit board 4, and each second side wall 342 defines a second solder pin 3420 for soldering to the circuit board 4.

From the above structure, it can be seen that through the metal part 34 of the present invention, the first side wall 340 is used to correspond to and cover the short side wall 302, and each second side wall 342 covers a portion of each long side wall 300 on the main body, and extends to the circuit board and surface mount technology (SMT) is used on the circuit board. Through the extended covering area of the first side wall 340 and each second side wall 342 in the metal part 34, the problem of insufficient strength in the prior art is effectively solved, so as to achieve the structural strength of the board-to-board plug connector 3 after being welded to the circuit board 4.
