Technical Field

The following description relates to a connector assembly, and more particularly, to a connector assembly including a receptacle connector and a plug connector slidably inserted into the receptacle connector.

Background

In various types of electronic devices (e.g., wired/wireless communication devices), internal circuits are implemented on circuit boards.

According to the plug connector 100 of the embodiment of the present invention, electromagnetic waves generated through the signal lines 310 and the outer conductors 330 of the cable 300 and the signal posts 110 are primarily shielded by the shielding cases 120 and 130 and secondarily shielded by the plug housing 150, thereby improving electromagnetic wave shielding performance. In addition, since electromagnetic waves between adjacent signal lines 310 or between adjacent signal pillars 110 are shielded by the shielding walls 122 in the shielding cases 120 and 130, interference between signals can be minimized.

Fig. 4A to 4C are views of a receptacle connector according to an embodiment of the present invention. Fig. 4A is a first exploded view of the receptacle connector 200 as viewed from the front upper side, fig. 4B is a second exploded view of the receptacle connector 200 as viewed from the front upper side, and fig. 4C is a second exploded view of the receptacle connector 200 of fig. 4B as viewed from the front lower side.

The receptacle connector 200 includes a clip 210, a receptacle base 220, a second insulative member 230, and a receptacle housing 240.

The lower surface of the first section 211 is in elastic contact with the signal pad of the circuit board P, and the upper end of the clip post 210 (i.e., the portion between the fourth section 214 and the fifth section 215) is in elastic contact with the lower surface 112a of the second portion 112 of the signal post 110. According to one embodiment, the lower surface of the first section 211 of the clip 210 may be electrically contacted with the signal pad of the circuit board P by a surface mount (SMD/SMT) method, an SIP method, which is a penetration method, a DIP method, a QIP method, or the like.
