A connector assembly includes a socket connector, and a plug connector including a plug housing and plug terminals disposed in the plug housing and each having a contact portion projected sideward out of the plug housing. The socket connector includes a socket housing defining an insertion space, plug terminals disposed in the socket housing and contact pads embedded in two opposite inner sidewalls of the insertion space to connect with the plug terminals and exposed in the insertion space. Two end edges of the inner sidewalls of the insertion space are designed with two arc-shaped guiding surfaces. A bottom of each contact pad is bent and embedded in the inner sidewall to realize a smooth connection of the contact pad and the guiding surface so as to guide the contact portions to be inserted into the insertion space along the guiding surfaces and electrically contact with the contact pads.
