Description

Technical Field [0001] The present invention relates to a connector device having a reinforcing coupling structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector device having a reinforced coupling structure, and more particularly, to a connector device having a reinforced coupling structure that can firmly maintain a state of engagement between a first connector and a second connector, .

Various electric and electronic devices are becoming increasingly smaller, thinner, lighter, and multifunctional. In the field of smart phones, notebooks, and cameras, there is a great need for miniaturization and thinning for versatility.

Such electrical and electronic equipment is constituted by installing a plurality of electric and electronic parts including a PCB circuit board therein and connecting them. The configuration in which these electric and electronic parts are electrically connected to each other is very important for downsizing and thinning It is an element to be considered.

In particular, various types of board to board (BtoB) connectors have been developed to connect a substrate and a substrate, but they have a disadvantage in that they are complicated in manufacturing and poor in bonding performance because they require a large number of components.

1 is a diagram illustrating a board to board (BtoB) connector for connecting a conventional substrate to a substrate. 1, the conventional B-to-B connector includes a male connector 10 and an female connector 20, and the male connector 10 is fitted to the female connector 20 to be 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, 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.

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 is caused, so that when the male and female connectors are to be separated for repairing the parts, the connector may be broken or the part coupled to the board may be separated.

The upper portion of the second projection 224 is convexly formed in the direction of the second fitting projection 124 from the lower portion of the second projection 224 with the second projection 224 as a reference, do. In order to allow the first latching part 125 to be engaged with the second latching part 225 to be freely disengaged from the second latching part 225, the convex lower part of the second fitting projection part 124 and the convex part of the second projection part 224 Since the third round portion 228 is configured to have an elastic force so as to be closer to the second protrusion 224 by the thickness of the upper portion, the third round portion 228 must extend in a direction away from the second protrusion 224, The third round portion 228 is configured such that the first round portion 228 can not be arbitrarily opened. Accordingly, the first engagement portion 125 has an effect of being firmly engaged with the second engagement portion 225, 121 and the second inner insertion terminal 221 are also maintained firmly.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It should be understood that the technical idea belonging to the scope of the claims also belongs to the present invention.
