Description

BOARD TO BOARD CONNECTOR

The present invention relates to a structure of a board-to-board connector, and more particularly, to a board-to-board connector having a metal member reinforcement member capable of fixing a metal member fastening member and a shield member having a fastening member departure prevention portion, A board connector (not shown) for preventing electromagnetic interference (EMI) of a connector generated at the time of operation and preventing arbitrary disconnection of the female connector and the male connector when the board-to- .

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, since the terminals 12 and 14 have the elastic characteristics of metal, when the external force is applied to the terminals 12 and 14 even when they are coupled to each other, they can be easily separated from each other while being elastically deformed again . In this case, the male and female connectors can be easily separated at the time of a slight impact or drop. Also, there is a disadvantage in that it is difficult to recognize whether the mutual coupling is completely completed by vibration or noise, that is, a so-called clicking feeling.

In order to prevent this, it is possible to deform the size and shape of the engaged protrusions more sharply so as to induce more rigid coupling, impact, and noise generating operation. In this case, however, the coupling itself becomes very difficult, There is a problem that breakage occurs, so that when the male and female connectors are to be removed for repairing the parts, the connector may be broken or the portion welded to the board such as the PCB may be separated.
