Description of the Related Art In recent years, connectors have been widely applied to circuit boards for portable terminals and the like, and slimmer and thinner has been required to meet the trend of miniaturization of electronic devices. In addition, as the density of electronic elements mounted on a circuit board increases, the number of contacts provided in the connector increases, and the narrow pitch and miniaturization of contacts are becoming very important.

1 is a perspective view showing a configuration of an electrical connector assembly according to the prior art.

1, the connector assembly includes a receptacle connector 10 in which a plurality of receptacle contacts 12 are arranged in the receptacle body 11, a receptacle connector 10 which is fitted in the receptacle connector 10 and has a receptacle contact 12, And a plug contact (22) in a one-to-one contact with the plug main body (21).

The receptacle contacts 12 and the plug contacts 22 are connected to the respective receptacle connector side cables and the plug connector side cables or mounted on the circuit board. The receptacle connector side cable and the plug connector side cable or circuit of the circuit board are electrically connected when the plug connector 20 is inserted into the receptacle connector 10 so that the receptacle contact 12 and the plug contact 22 are in contact with each other .

When the receptacle connector 10 and the plug connector 20 are fastened in a state where the alignment of the plug connector 20 is not properly engaged, the connector assembly having the above-described structure is mechanically and electrically connected between the receptacle contact 12 and the plug contact 22 Fatal contact failure occurs due to improper contact. As an alternative to this problem, a guide protrusion 13 protruding from the upper surface of the receptacle connector 10 is provided around the four corners of the receptacle connector 10 to guide insertion of the plug connector 10. The guide protrusion 13 is formed integrally with the receptacle connector 10 when molding the receptacle connector 10 using an insulating resin.

FIG. 2 is a perspective view showing a structure of a receptacle contact according to the prior art, FIG. 3 is a perspective view showing the structure of a plug contact according to the related art, FIG. 4 is a perspective view showing a mounting pattern layout Fig.

However, since the conventional receptacle contacts 12 and plug contacts 22 employ a one-point contact structure, there is a problem that stable connection is difficult. In order to solve this problem, the receptacle contact 12 has a structure in which the receptacle contact 12 is bent. However, in order to maintain the strength of the receptacle contact 12, the thickness of the receptacle contact 12 must be increased.
