An electrical connector includes a barrel type terminal, having a first connecting area and a second connecting area. The first connecting area has a first non-soldering surface and a first soldering surface. The second connecting area has a second non-soldering surface and a second soldering surface. Each of the first and second soldering surfaces and the first and second non-soldering surfaces has a first solder layer. A sleeve sheathes outside the barrel type terminal, and has a first fixing area and a second fixing area. Two second solder layers are provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface. The amount of solder provided between the first fixing area and the first soldering surface and between the second fixing area and the second soldering surface is greater than that provided on the first and second non-soldering surfaces.
