A cable connector for soldering to a cable defining some core wires includes an insulative body, a plurality of terminals, and a spacer. Each terminal includes a soldering portion extending rearwardly out of the insulative body soldering to the core wires. The spacer includes some stalls and a respective receiving slot formed between every two adjacent stalls for receiving the soldering portions. The receiving slot includes a first receiving slot proximal to the insulative body and a second receiving slot distal from the insulative body. The second receiving slot includes a lower receiving space and an upper receiving space with a smaller width. The soldering portion of the terminal includes a first portion received in the lower receiving space and a second portion received in the first receiving slot. The width of the first portion is larger than the width of the second portion to reduce the impedance.
