Electric connector

Claim 2

An electric connector, comprising a pair of female and male housings formed for fitting engagement with each other in one direction, the housings having terminals that electrically engage each other as the housing are mated, a locking arm means provided on an outer wall of said male housing by way of a base portion and extending in parallel to the fitting direction, said locking arm means being capable of resiliently deformed in a direction perpendicular to the fitting direction, a first engaging means formed on said locking arm means said female housing having a casing portion for receiving said male housing therein, said casing portion having an opening through which a disengaging action is accessible to said locking arm means, a first arresting means provided on said casing portion for engaging with said first engaging means in a fully fitted position of said female and male housings to lock said female and male housings to each other in the fully fitted position, a second engaging means formed at a location on said locking arm means forwardly of said first engaging means, and a second arresting means provided on said casing portion of said female housing for engaging with said second engaging means in a half-fitted position of said female and male housings to temporarily lock said female and male housings to each other in the half-fitted position.

Claim 3

An electric connector as claimed in claim 1, wherein said base portion by way of which said locking arm means is provided on said outer wall of said male housing is an upwardly extending base portion.

Claim 4

An electric connector as claimed in claim 1 or 2, wherein said locking arm means is capable of being resiliently deformed in an up and down direction, and said first engaging means is provided on an upper face of said locking arm means.

Claim 5

An electric connector as claimed in any one of claims 1 or 2, wherein said locking arm means consists of a first locking arm and a second locking arm, said second locking arm is provided on at least one side of said first locking arm between said first locking arm and said outer wall of said male housing for being resiliently deformed in a direction perpendicular to the fitting direction, and said second engaging means is provided on said second locking arm.

Claim 6

An electric connector as claimed in claim 4, wherein said second locking arm is capable of being resiliently deformed in a direction perpendicular to the direction in which said first locking arm is capable of being resiliently deformed.

Claim 7

An electric connector as claimed in claim 1 or 2, wherein said locking arm means consists of a first locking arm and a second locking arm, said second locking arm being provided in a juxtaposed relationship to said first locking arm such that they may be capable of being resiliently deformed in the same direction.

Claim 8

An electric connector as claimed in claim 3, wherein said locking arm means consists of a first locking arm and a second locking arm, said locking arm being provided in a juxtaposed relationship to said first locking arm such that they may be capable of being resiliently deformed in the same direction.

Claim 9

An electric connector assembly comprising: at least two members including a first member having an arm support portion and a second member having a casing portion adapted for fitting engagement with said first member in one direction, the members having terminals that electrically engage each other as the members are mated; locking arm means provided on said arm support portion of said first member to extend in parallel to said one direction, said locking arm means including a base portion erected on an outer wall of said first member, a first locking arm (6) extending from said base portion in a plane extending parallel to said support portion and a second locking arm (7) extending on a first lateral side of said first locking arm to define a space in cooperation with said support portion of said first member, said space allowing resilient deformation of said first locking arm and said second locking arm thereinto; first engaging means (6b) formed on said first locking arm; first arresting means (10) provided on said casing portion for engagement with said first engaging means (6b) in a fully fitted position of said first and second members to lock said first and second members to each other in the fully fitted position; second engaging means (7a) formed on said second locking arm (7) forwardly of said first engaging means; second arresting means (11) provided on said casing portion of said female housing forwardly of said first arresting means (10) for engaging with said second engaging means (7a) in a half-fitted position of said first and second members to temporarily lock said first and second member to each other in the half-fitted position.

Claim 10

An electric connector assembly comprising: at least two members including a first member having an arm support portion and a second member having a casing portion adapted for fitting engagement with said first member in one direction, the members having terminals that electrically engage each other as the members are mated; locking arm means provided on said arm support portion of said first member to extend in parallel to said one direction, said locking arm means including a base portion erected on an outer wall of said first member, a first locking arm (6) extending from said base portion in a plane extending parallel to said support portion and a second locking arm (7) extending on a first lateral side of said first locking arm to define a space in cooperation with said support portion of said first member, said space allowing resilient deformation of said first locking arm and said second locking arm thereinto; first engaging means (6b) formed on said first locking arm; first arresting means (10) provided on said casing portion for engagement with said first engaging means (6b) in a fully fitted position of said first and second members to lock said first and second members to each other in the fully fitted position; second engaging means (7a) formed on said second locking arm (7) forwardly of said first engaging means; second arresting means (11) provided on said casing portion of said female housing forwardly of said first arresting means (10) for engaging with said second engaging means (7a) in a half-fitted position of said first and second members to temporarily lock said first and second member to each other in the half-fitted position.

Claim 11

An electric connector assembly according to claim 8, wherein said first member includes a male housing and said second member includes a female housing.

Claim 12

An electric connector assembly according to claim 9, wherein said casing portion of said female housing has an opening through which a disengaging action is accessible to said first locking arm.

Claim 13

An electric connector assembly according to claim 8, wherein said second locking arm extends in a perpendicular plane to said support portion of said first member.

Claim 14

An electric connector assembly according to claim 8, wherein said second locking arm extends substantially parallel to said support portion.

Claim 15

An electric connector assembly according to claim 11 or 12, further including a third locking arm on a second lateral side of said first locking arm.
