Abstract: A connector assembly includes a connector module, a first shell located outside the connector module, and a second shell injection-molded outside the first shell. The first shell has a first slot and a second slot in communication with each other, and a first fixing portion relatively close to the connector module and a second fixing portion. The second fixing portion has a first abutting surface forming a portion of the first slot and a second abutting surface forming a portion of the second slot. The second shell has at least a clip portion filled in the first slot and the second slot. The clip portion abuts the first abutting surface and the second abutting surface simultaneously. An included angle between a direction of the clip portion abutting the first abutting surface and a direction of the clip portion abutting the second abutting surface is less than 180 degrees.
