A miniature multiple electrical connector consists of a plug connector and a receptacle connector having an insulating block and a metal shell. The metal shell is fixed to the insulating block by fitting anchoring protrusions provided along both sides of the insulating block in anchoring apertures of fixing tongues provided on the metal shell. When the plug connector is being inserted into the receptacle connector, the metal shell of the receptacle connector is likely to be deformed by a metal shell of the plug connector. In order to prevent such a deformation of the metal shell, there is provided means for anchoring the center of the metal shell weakest in mechanical strength to the insulating block or means for preventing application of a force to the center of the metal shell when the plug connector is being inserted into the receptacle connector.
A miniature multiple electrical connector including a plug connector and a receptacle connector, said plug connector including an insulating block having contacts arranged on a fitting protrusion thereof and a metal shell fixed to the insulating block to surround the fitting protrusion with clearances therearound, and said receptacle connector including an insulating block having contacts arranged on a fitting recess thereof and a metal shell fixed to the insulating block around its fitting recess and to be in contact with the inside of the metal shell of the plug connector upon mating the plug and receptacle connectors with each other, said insulating block and said metal shell of the receptacle connector being fixed to each other by fitting anchoring protrusions provided along both sides of the insulating block of the receptacle connector in anchoring apertures of fixing tongues provided on the metal shell of the receptacle connector, wherein the metal shell of the plug connector is formed with deformation preventing notches, one on each side thereof, whose center is deeper than both ends of the notch, each notch extending from a leading edge of the metal shell.
