Abstract

Abstract A switch connector assembly with a waterproof structure which prevents admission of water thereinto without certainty and complete fitting between male and female connectors can be confirmed readily. The female connector has a short-circuiting terminal extending into a connector fitting chamber thereof and further has a temporary arresting projection and a flexible locking arm having a final arresting projection thereon. The male connector has a connecting terminal, a flexible engaging pawl, and an engaging 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, but contact with each other when the final arresting projection is fitted with the engaging portion. A sliding seal is provided on an outer periphery of the male connector and is engaged, upon insertion of the male connector into the connector fitting chamber, with the inner wall of the connector fitting chamber simultaneously with fitting of the temporary arresting projection and the flexible engaging pawl with each other.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 230 words
A switch connector assembly with a waterproof structure, comprising: a first connector having a connector fitting chamber formed therein and having a short-circuiting terminal extending therefrom into said connector fitting chamber, said first connector having thereon a temporary arresting projection and a flexible locking arm having a final arresting projection thereon; a second connector for being inserted in said connector fitting chamber, said second connector having thereon a connecting terminal for contacting with said short-circuiting terminal, a flexible engaging pawl for engaging with said temporary arresting projection, and an engaging portion for engaging with said final arresting projection; said first and second connectors being so shaped and dimensioned that said short-circuiting terminal and said connecting terminal are kept out of contact with each other when said temporary arresting projection is fitted with said flexible engaging pawl, but contact with each other when said final arresting projection is fitted with said engaging portion; and a sliding seal provided on an outer peripheral wall adjacent an end of said second connector for engaging with an inner wall of said connector fitting chamber, said sliding seal being located so as to be engaged, when said second connector is inserted into said connector fitting chamber of said first connector, with said inner wall of said connector fitting chamber simultaneously when said temporary arresting projection and said flexible engaging pawl are fitted with each other.
Claim 2
Dependent Claim 72 words
A switch connector assembly with a waterproof structure as claimed in claim 1, further comprising a fixing seal provided on said outer peripheral wall adjacent a base end of said second connector, said fixing seal being closely contacted with said second connector simultaneously when said final arresting projection and said engaging portion are fitted with each other upon insertion of said second connector into said connector fitting chamber of said first connector.
Claim 3
Dependent Claim 27 words
A switch connector assembly with a waterproof structure as claimed in claim 2, wherein said sliding seal and said fixing seal are formed as a unitary member.
Claim 4
Dependent Claim 49 words
A switch connector assembly with a waterproof structure as claimed in claim 1, wherein a taper guide is formed at an opening end portion of an inner wall of said connector fitting chamber for guiding said sliding seal upon insertion of said second connector into said connector fitting chamber.
Claim 5
Dependent Claim 75 words
A switch connector assembly with a waterproof structure as claimed in claim 1, wherein a recessed groove is provided circumferentially at an intermediate portion of an inner wall of said connector fitting chamber in the inserting direction of said second connector into said first connector in such a manner that said sliding seal is not contacted with the inner wall of said fitting chamber when said second connector is inserted into said connector fitting chamber.
Claim 6
Dependent Claim 28 words
A switch connector assembly with a waterproof structure as claimed in claim 5, wherein said recessed groove extends to an opening end portion of said connector fitting chamber.
