Abstract

The utility model relates to a connector against mistake insert, which comprises a housing, wherein the inner part of the housing is provided with a first jack assembly, and one end of the housing is provided with a first opening and a containable hole. A first terminal set and a strip against mistake insert are fixed in the first jack assembly. The strip against mistake insert is an n-shaped strip body. A catch pin is arranged on one end of the strip against mistake insert. Two barrier chips are respectively connected with both sides of the catch pin opposite to the containable hole. If users insert plugs with minor width into the first opening with wider width, the catch pin stops the plug and the plug can not be inserted into the first jack assembly. Inversely, if the width of the plug matches with the first opening, the plug pulls the barrier chip into the containable hole and the displacement of the catch pin connected with the barrier chip makes the plug insert into the first jack assembly easily.
