(US5224872-A)      The female connector has a short-circuiting terminal extending into a connector fitting chamber. It further has a temporary arresting projection and a flexible locking arm having a final arresting projection on it. The male connector has a connecting terminal, a flexible engaging pawl, and an engagng portion.    The short-circuiting terminal and the connecting terminal are kept out of contact with each other when the temporary arresting projection is fitted with the flexible engaging pawl. They contact with each other when the final arresting projection is fitted with the engaging portion.    USE/ADVANTAGE -   A switch connector assembly with a waterproof structure which prevents admission of water into it without certainty, and complete fitting between male and female connectors can be confirmed readily.    (EP537751-B1)      A switch connector assembly providing for the electric connection of electrical elements with a waterproof structure, comprising: a first connector (16) having a connector fitting chamber (41) formed therein and having a short-circuiting terminal (19) extending therefrom into said connector fitting chamber (41), said first connector (16) having thereon a temporary arresting projection (35) and a flexible locking arm (27) having a final arresting projection (26) thereon, a second connector (17) comprising a terminal accommodation portion (40), for being inserted in said connector fitting chamber (41), said second connector having thereon a connecting terminal (20) for contacting with said short-circuiting terminal (19), a flexible engaging pawl (37) for engaging with said temporary arresting projection (35), and an engaging portion (32) for engaging with said final arresting projection (26); said first and second connectors (16, 17) being so shaped and dimensioned that said short-circuiting terminal (19) and said connecting terminal (20) are kept out of contact with each other when said temporary arresting projection (35) is fitted with said flexible engaging pawl (37), but contact with each other when said final arresting projection (26) is fitted with said engaging portion (32) characterised by further comprising: a sliding seal (45) provided on an outer peripheral wall (43) adjacent an end of said second connector (17) for engaging with an inner wall (44) of said connector fitting chamber (41), said sliding seal (45) being located so as to be engaged, when said second connector (17) is inserted into said connector fitting chamber (41) of said first connector (16), with said inner wall (44) of said connector fitting chamber (41) simultaneously when said temporary arresting projection (35) and said flexible engaging pawl (37) are fitted with each other.
