Electric connector and detection terminal included therein

摘要

An electric connector includes a housing to be fit into a second electric connector, a lock arm resiliently deforming when the lock arm makes contact with an engagement part of the second electric connector, and thereafter, returning back to its original position, when the electric connector and the second electric connector are coupled to each other, a first detection terminal for detecting whether the electric connector and the second electric connector are electrically connected to each other, and a unit for assisting the lock arm to return back to the original position, the lock arm, the first detection terminal, and the unit being arranged in the housing, the detection terminal including a first portion to be fixed relative to the lock arm, and a second portion to make contact with a second detection terminal of the second electric connector.

主权项

1. An electric connector including:
a housing to be fit into a second electric connector; a lock arm resiliently deforming when said lock arm makes contact with an engagement part of said second electric connector, and thereafter, returning back to its original position, when said electric connector and said second electric connector are coupled to each other; a first detection terminal for detecting whether said electric connector and said second electric connector are electrically connected to each other; and a unit for assisting said lock arm to return back to said original position, said lock arm, said first detection terminal, and said unit being arranged in said housing, said first detection terminal including a first portion to be fixed relative to said lock arm, and a second portion to make contact with a second detection terminal of said second electric connector, said unit being formed, as a part of said first detection terminal, integral with said first portion, said unit having a free end which makes contact with a portion of said second electric connector when said housing and said second electric connector are coupled to each other, said unit exerting a reaction force onto said lock arm through said first portion fixed relative to said lock arm where said free end making contact with said portion acts as a fulcrum, said second electric connector being formed therein with a slope ascending towards a proximal end thereof from an opening end thereof, said unit making contact with said slope when said electric connector is fit into said second electric connector.
