Electrical connector
An electrical connector, including an insulating body, multiple terminals, a metal shell, a collar, and a water-proof glue, is provided. The terminals are disposed in the insulating body. The metal shell is disposed outside the insulating body and surrounds the insulating body and the terminals. The collar is sleeved onto an outer wall of the metal shell. The collar has a first plate portion, a second plate portion, and a bending portion. The bending portion is connected between the first plate portion and the second plate portion. The first plate portion is connected to the outer wall of the metal shell, and the second plate portion is away from the outer wall of the metal shell. The water-proof glue is disposed between the second plate portion of the collar and the bending portion and the outer wall of the metal shell.
