Abstract

Abstract A cover for covering a lock arm is mounted through a self hinge portion on an upper surface of a female housing for pivotal movement between an open and a closed position, and a non-engagement detection projection is formed on a back surface of the cover at a proximal end portion thereof. When the cover is pushed by an operator to be closed, the lock arm slants forwardly upwardly with a hook portion placed on an engagement portion formed on a male housing. If the male and female housings are not engaged with each other, and therefore the non-engagement detection projection abuts against the lock arm, the cover is held in a raised condition thus indicating that the housings are not engaged with each other. Because the cover is mounted integrally on the housing, the number of the component parts is reduced, and extra management of the parts and extra assembling steps are eliminated.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 108 words
A connector adapted to be releasably fitted relative to a mating connector, comprising a connector housing having a lock arm that is engageable with an engagement portion provided on a housing of said mating connector to hold the two housings in an engaged condition; a cover for covering said lock arm mounted through a self-hinge portion on said connector housing for pivotal movement between an open position and a closed position; and a non-engagement detection projection for maintaining said cover in a raised position when said lock arm is not engaged, said non-engagement detection portion being formed on at least one of said lock arm and said cover.
Claim 2
Dependent Claim 37 words
A connector according to claim 1, wherein said cover is provided with a retaining portion that is engageable with said connector housing to hold said cover in such a condition that said cover covers said lock arm.
Claim 3
Dependent Claim 72 words
A connector comprising: a housing; a lockarm pivotably engaged to said housing, said lockarm including a hook portion adapted to engage with an engagement portion of a mating connector; a cover pivotably mounted on said housing; and a non-engagement detection projection mounted on at least one of said cover and said lockarm for providing interference between said cover and said lockarm when the connector is not properly fitted with said mating connector.
Claim 4
Dependent Claim 18 words
The connector of claim 3, wherein said lockarm is pivotably mounted on a fulcrum located on said housing.
Claim 5
Dependent Claim 35 words
The connector of claim 3, wherein said engagement portion and said non-engagement detection projection each include a first inclined surface and a second surface, and said interference is provided when said inclined surfaces are engaged.
Claim 6
Dependent Claim 32 words
The connector of claim 5, wherein a fully connected position is achieved when said inclined surfaces disengage and said second surfaces engage, thereby preventing said interference between said cover and said lockarm.
Claim 7
Dependent Claim 15 words
The connector of claim 3, wherein said non-engagement detector projection is formed on said cover.
Claim 8
Dependent Claim 25 words
The connector of claim 3, wherein said cover is pivotably connected to said housing with a self-hinge that biases the cover to an open position.
Claim 9
Dependent Claim 38 words
The connector of claim 3, wherein the cover includes at least one retaining portion having a retaining pawl that is engageable with a retaining hole formed in said housing when said cover and said lockarm do not interfere.
Claim 10
Independent Claim 125 words
A method of connecting first and second connectors and visually indicating a properly connected condition, the first connector including a housing having a pivotable cover and lockarm that includes a hook portion engageable with an engagement portion formed on said second connector, said method comprising the steps of: sliding the first and second connectors together so as to make contact between the hook portion and the engagement portion; pivoting said cover relative to said housing; engaging the cover and the lockarm in an interfering manner to indicate an incomplete connection when the first and second connectors are not fully engaged; and connecting a distal end of the cover with the housing to indicate a complete connection when the first and second connectors are fully engaged.
Claim 11
Dependent Claim 50 words
The method of claim 10, wherein the distal end of the cover includes retaining portions having locking pawls that are engageable with corresponding retaining holes formed in the housing, and the connecting step includes inserting the locking pawls in the retaining holes to maintain the indication of a complete connection.
Claim 12
Dependent Claim 21 words
The method of claim 10, wherein the pivoting step includes pivoting the cover about a self-hinge member mounted to said housing.
Claim 13
Dependent Claim 35 words
The method of claim 10, further comprising providing the cover with a non-engagement detection portion and the step of engaging includes engaging the non-engagement detection portion with the hook portion to indicate said incomplete connection.
Claim 14
Dependent Claim 62 words
A connector comprising a housing having a lockarm and an cover pivotably mounted on the housing, said lockarm including a lock portion that is engageable with an engagement portion formed on a mating connector, and means for indicating an incomplete connection and for providing interference between said cover and said lockarm when the connector is not properly fitted with said mating connector.
Claim 15
Dependent Claim 38 words
The connector of claim 14, wherein said means includes a non-engagement detection portion formed on at least one of said cover and said lock arm for urging said cover in an open position to indicate said incomplete connection.
