In the field of smart phones, notebooks, and cameras, there is a great need for miniaturization and thinning for versatility. Such electric and electronic equipment includes a PCB circuit board and a variety of electric and electronic components installed therein. The configuration in which these electric and electronic components are electrically connected to each other is a very important factor for miniaturization and thinning . Various board-to-board (B-to-B) connectors have been developed to connect between a substrate and a substrate. However, since a large number of components are required to manufacture the connector, .

1 is a diagram illustrating a board to board (BtoB) connector for connecting a conventional substrate to a substrate. Referring to FIG. 1, a conventional B-to-B connector includes a male connector 10 and an female connector 20, and the male connector 10 is fitted in the female connector 20 so that the male connector 10 is electrically connected.

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, each of the terminals 12 and 14 is provided with a protruding portion facing each other, so that these portions are mutually overtightly engaged with each other to generate a coupling force.

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.

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 of causing breakage.

In order to solve this problem, Korean Patent Registration No. 10-1116410 discloses a connector having a socket and a header, in which a coupling member is provided in each of a socket and a header, .

2 is a schematic view of a connector having a conventional socket and a header. 2, the socket 60 includes a socket base 62, a plurality of socket contacts 64 provided inside the socket base 62, and a plurality of socket contacts 64 provided at both ends of the socket base 62 And a coupling member 66 for a socket. The header 50 includes a header base 52 inserted into the socket base 62, a plurality of header contacts 54 provided inside the header base 52, a header base 52, And a header joining member 56 provided at both ends of the header. When the socket base 62 and the header base 52 are coupled to each other, the socket contact 64 and the header contact 54 are brought into contact with each other to be electrically connected to each other, The engaging members 56 are coupled to each other. At this time, the header coupling member 56 is formed in an elastically deformable arch shape, and protruding portions 56a are formed at both ends of the header coupling member 56. The socket coupling member 66 is formed to receive the header coupling member 56 And a retaining portion 66a coupled to the protruding portion 56a is formed at a position opposite to the protruding portion 56a. When the header 50 is coupled to the socket 60, the header engaging member 56 is resiliently deformed and inserted into the socket engaging member 66 and returned to the original state. At this time, Portions 66a are fitted to each other.

However, the header engaging member 56 and the socket engaging member 66 can not firmly protect both ends of the header base 52 and both ends of the socket engaging member 66, There is a problem that the end of the header base 52 and the end of the socket base 62 are damaged when the header base 52 is attempted to be joined at a slightly oblique angle instead of the correct position of the socket base 62. [ .

As the thickness of the electronic apparatus is reduced, there is a strong demand for lowering the thickness of the connector for connecting the board of the electronic apparatus with the board. In the conventional connector, the socket contact 64 is fitted to the socket base 62 , There is a problem in that it is difficult to lower the thickness of the connector because of a separate structure for fitting them.
