Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a board connector having a reinforcing plate,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board connector having a reinforcing plate, and more particularly, to a board connector for connecting a board and a board by arranging a reinforcing plate on both left and right sides of a board connector, To a board connector provided with a reinforcing plate capable of simultaneously realizing a high current transmission and a fastening structure of a signal and a ground terminal.

In general, the board to board (BtoB) connector is used to connect boards with various circuit printed boards. As shown in FIG. 1, the B-to-B connector includes a male connector 10 and a female connector 20, and the male connector 10 is fitted to the female connector 20 so that the female connector 20 can be coupled to each other.

Once the male connector 10 and the female connector 20 are inserted and fastened, they are required to maintain the fastened state, but they may be separated from each other by an external force. In order to prevent this, as shown in the figure, the terminals 12 and 14 are provided with protruding portions facing each other, so that these portions are mutually engaged with each other by elasticity so that a coupling force is generated.

However, in the case of a board to board (BtoB) connector (hereinafter referred to as a board connector), the male connector 10 and the female connector 20 are easily separated from each other without a separate reinforcing plate The reliability of the product is deteriorated.

Furthermore, in the case of a high-current board connector, there is a need for separately configuring a high-current terminal and a circuit so as to transfer a larger allowable current amount than in a conventional terminal.

In addition, a board connector of a simple terminal fastening structure capable of simultaneously realizing a high current transmission and a fastening structure of a signal and a ground terminal has not been proposed at all.
