Welding connection structure of terminal of electronic device and printed circuit board

Abstract

The present invention provides a welding connection structure between a terminal of a electron device with improving mounting strength of a plug (3) on a printed circuit board (1) and a printed circuit board without increasing welding area of a circuit board. Matching the plug (3) at an incision (11) at the edge of the printed circuit board (1), and welding a connecting terminal (72, 72) of a shielding cover of the plug (3) on a solder pad of the printed circuit board (1), forming first and second solder pad (13, 13, 15, 15) at side and edge of the incision (11), the connecting terminal (72, 72) provided with first and second connector (73, 73, 75, 75) of the plug welding connecting with the first and second solder pad (13, 13, 15, 15) toward the incision (11).

Description

technical field [0001] The present invention relates to a solder connection structure of a terminal of an electronic device (such as a connector) and a printed circuit board having a cutout or a through hole for fitting the electronic device. [0002] In particular, it relates to a solder connection structure between a terminal and a printed circuit board suitable for mounting small electronic devices such as small SUB connectors for mobile phones and personal computers on a printed circuit board. Background technique [0003] In the past, in the solder connection structure of such a terminal and a printed circuit board, there is known a structure in which in order to suppress the protruding height from the surface of the printed circuit board and realize thinning and miniaturization, A cutout or through-hole structure that can fit electronic devices is provided. (For example, refer to Patent Document 1: JP-A-2000-133391 or Patent Document 2: JP-A-2004-79407). [0004] In ...

Problems solved by technology

[0006] However, in Figure 20 In the conventional example shown in FIG. 21, although the occupied area required for the solder connection on the printed circuit board 105 can be reduced, there is a change in the strength (mounting strength) of fixing the connector 103 on the printed circuit board 105. weak question

[0007] In addition, in Figure 22 In the existing example shown, there is also the same Figure 20 21, and since it is necessary to form a plurality of holes for inserting plug-in terminals 206 to 206 on the printed circuit board 202, the required circuit board occupation area becomes larger, and there is a problem that the printed circuit board 202 cannot be The other side of the side panel is used for circuit configuration issues

[0008] In addition, if the number of surface mount terminals 205 to 205 is increased in order to increase the mounting strength, there is a problem that the assembly work becomes complicated.

[0009] In addition, in Figure 20 21, it is also considered to form terminal insertion holes on the printed circuit board 105, insert the connection terminals of the connector 103 into the insertion holes, and solder the connection parts to the structure on the pad, but since the terminal insertion holes are required Therefore, there is a problem that the occupied area required for the solder connection on the printed circuit board becomes large, and the board surface on the opposite side to the connector mounting surface of the printed circuit board cannot be used for circuit configuration.
