Apparatus for checking the connection between male and female connector housings by forming a detecting circuit when the connection is proper

An apparatus, provided in a waterproof connector including a pair of connector housings to be connected to each other, for checking whether or not said pair of connector housings of said connector have been engagedly connected with each other, said pair of connector housings including a male connector housing and a female connector housing, said male connector housing including a concave portion and said female connector housing including a mounting section;

• said apparatus comprising:
• a conductive seal ring, made of a conductive material, provided in said male connector housing;
• and
• a pair of detecting terminals provided in said female connector housing,
• wherein a detecting circuit comprising said detecting terminals and said conductive seal ring is formed by the contact between said detecting terminals and said conductive seal ring when said male and female connector housings contact with each other, and
• further wherein said conductive seal ring is mounted under pressure between an outer periphery of said mounting section of said female connector housing and an inner periphery of said concave portion of said male connector housing when said male and female connector housings are in a connected condition, to attendantly provide a waterproof connection between said male connector housing and said female connector housing.
