Abstract

Abstract In order to detect via an external circuit whether male and female connector housings 1 and 2 have been correctly fitted together, a short-circuiting terminal 19 which bends when a locking arm 10 bends either short circuits or fails to short circuit a pair of detecting terminals 7 located on the male housing 1. The area surrounding the short-circuiting terminal 19 is surrounded by an interior protecting wall which is covered by a flexible sealing cover 27. The sealing cover covers only the short-circuiting terminal and the locking arm remains exposed. The upper face of the interior protecting wall has an opening 25A. When the locking arm 19 is bent while the housings are being fitted, the short-circuiting terminal 19 is moved via the sealing cover 27 and the short-circuiting terminal and the detecting terminals 7 separate.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 83 words
An electrical connector having an exposed bendable latch arm for engagement with a mating connector in the fully fitted condition, and a short-circuit terminal engageable with a detecting terminal of a mating connector so as to complete an electrical circuit only in the fully fitted condition, characterized in that said connector further includes a flexible sealing cover, said short-circuit terminal being protected from moisture by said cover, and wherein said short-circuit terminal is movable by said exposed latch arm acting through said cover.
Claim 2
Dependent Claim 83 words
An electrical connector having an exposed bendable latch arm for engagement with a mating connector in the fully fitted condition, and a short-circuit terminal engageable with a detecting terminal of a mating connector so as to complete an electrical circuit only in the fully fitted condition, characterized in that said connector further includes a flexible sealing cover, said short-circuit terminal being protected from moisture by said cover, and wherein said short-circuit terminal is movable by said exposed latch arm acting through said cover.
Claim 3
Dependent Claim 24 words
An electrical connector according to claim 1 wherein said cover and said latch arm are attached so as to move in a unified manner.
Claim 4
Dependent Claim 43 words
An electrical connector according to claim 1 and further including a protecting member co-moulded in a wall of said cover between said short-circuit terminal and latch arm, said protecting member preventing direct contact between a wall of said cover and said short-circuit terminal.
Claim 5
Dependent Claim 38 words
An electrical connector according to claim 1 characterized in that said connector includes a chamber for housing said short-circuit terminal, said chamber having an open end, and said cover comprising a resilient boot to close said open end.
Claim 6
Dependent Claim 24 words
An electrical connector according to claim 4 wherein said cover and said latch arm are attached so as to move in a unified manner.
Claim 7
Dependent Claim 25 words
An electrical connector according to claim 1 and further including a protecting member intermediate said short-circuit terminal and said cover to prevent direct contact therebetween.
Claim 8
Dependent Claim 21 words
An electrical connector according to claim 6 wherein said protecting member is moulded of plastics material directly on said short-circuit terminal.
Claim 9
Dependent Claim 19 words
An electrical connector according to claim 6 wherein said protecting member is a resilient cap of said short-circuit terminal.
Claim 10
Dependent Claim 17 words
An electrical connector according to claim 8 wherein said protecting member is adhered to said short-circuit terminal.
Claim 11
Dependent Claim 16 words
An electrical connector according to claim 6 wherein said protecting member is provided on said cover.
Claim 12
Dependent Claim 16 words
An electrical connector according to claim 10 wherein said protecting member is adhered to said cover.
Claim 13
Dependent Claim 19 words
An electrical connector according to claim 10 wherein said protecting member is relatively rigid in comparison with said cover.
Claim 14
Dependent Claim 16 words
An electrical connector according to claim 12 wherein said protecting member is adhered to said cover.
