The present invention relates to a board-to-board connector module, and more particularly to a board-to-board connector module that reduces the height and reduces components to reduce cost.

As consumer electronics continue to move toward light, thin, short, and small directions, such as in mobile devices such as mobile phones and PDAs and digital cameras, connectors are required for miniaturization and portable design of mobile devices. The module size is reduced and has a low profile feature. In addition, the versatility of mobile communication development, therefore, the density of electronic components mounted on the circuit board is increased, and the correspondingly arranged plug and socket terminals are required. Therefore, the continuous thinning and miniaturized connector modules are the trend and trend of research and development in the present day.

For example, the Republic of China Patent Publication No. 201034312 discloses a board-to-board connector module whose structure mainly includes a male-female end connector, and the structure of the male-female end connector can be subdivided into a male-female end insulating body.
