Abstract
Abstract The object of the invention is to allow a fitting operation lever to be set to an initial position with respect to a connector without particularly using a separate member such as a spring, the initial position being such a position as to allow driven pins of a mating connector to be received smoothly. The connector being made of a synthetic resin and having in a housing body thereof guide notches that receive the driven pins of the mating connector; and a fitting operation lever being made of the synthetic resin, the fitting operation lever having drive cam grooves corresponding to the driven pins and being pivotably disposed on the connector. An engagement portion disposed on the fitting operation lever is disposed so as to be releasable from an initial position setting lock portion disposed on the connector. Entrance portions of the drive cam grooves coincide with the guide notches at an initial position set condition in which the engagement portion is engaged with the initial position setting lock portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
151 words
A connector comprising: a connector housing having guide notches formed on side surfaces of said connector housing for receiving driven pins of a mating connector; a fitting operation lever pivotally disposed on the connector housing, and having drive cam grooves corresponding to the driven pins disposed on operation plate portions of the fitting operation lever; an initial position setting lock portion disposed on an upper surface of the connector housing, said upper surface of said connector housing extending between said side surfaces; an engagement portion arranged on an operation portion of the fitting operation lever for engaging with the initial position setting lock portion, wherein said operation portion extends between said operation plate portions when the fitting operation lever is in an initial position set condition, entrance portions of the drive cam grooves coincide with the guide notches and the engagement portion is engaged with the initial position setting lock portion.
Claim 2
Dependent Claim
151 words
A connector comprising: a connector housing having guide notches formed on side surfaces of said connector housing for receiving driven pins of a mating connector; a fitting operation lever pivotally disposed on the connector housing, and having drive cam grooves corresponding to the driven pins disposed on operation plate portions of the fitting operation lever; an initial position setting lock portion disposed on an upper surface of the connector housing, said upper surface of said connector housing extending between said side surfaces; an engagement portion arranged on an operation portion of the fitting operation lever for engaging with the initial position setting lock portion, wherein said operation portion extends between said operation plate portions when the fitting operation lever is in an initial position set condition, entrance portions of the drive cam grooves coincide with the guide notches and the engagement portion is engaged with the initial position setting lock portion.
Claim 3
Dependent Claim
155 words
A connector comprising: a connector housing having guide notches on side surfaces thereof for receiving driven pins of a mating connector; a fitting operation lever pivotally disposed on the connector housing, said fitting operation lever having a pair of operation plate portions extending from an operation portion and confronting the side surfaces, and having drive cam grooves corresponding to the driven pins on the operation plate portions; positioning grooves having initial position setting lock portions and fitting locked condition checking tapered portions distant from the initial position setting lock portions, said positioning grooves being formed on the side surfaces of the connector housing; positioning engagement portions corresponding to the positioning grooves disposed on the operation plate portions; and fitting position engagement portions disposed on the fitting operation lever for engaging with a fitting condition lock portion on the mating connector when the positioning engagement portions are abutted against the fitting locked condition checking tapered portions.
Claim 4
Dependent Claim
155 words
A connector comprising: a connector housing having guide notches on side surfaces thereof for receiving driven pins of a mating connector; a fitting operation lever pivotally disposed on the connector housing, said fitting operation lever having a pair of operation plate portions extending from an operation portion and confronting the side surfaces, and having drive cam grooves corresponding to the driven pins on the operation plate portions; positioning grooves having initial position setting lock portions and fitting locked condition checking tapered portions distant from the initial position setting lock portions, said positioning grooves being formed on the side surfaces of the connector housing; positioning engagement portions corresponding to the positioning grooves disposed on the operation plate portions; and fitting position engagement portions disposed on the fitting operation lever for engaging with a fitting condition lock portion on the mating connector when the positioning engagement portions are abutted against the fitting locked condition checking tapered portions.
Claim 5
Dependent Claim
35 words
A connector as claimed in claim 2, wherein the fitting operation lever is expanded by abutting the positioning engagement portions against the initial position setting lock portions and the fitting locked condition checking tapered portions.
Claim 6
Dependent Claim
30 words
A connector as claimed in claim 2, wherein the operation plate portions are released from the initial position setting lock portions by fitting the mating connector to the connector housing.
Claim 7
Dependent Claim
40 words
A connector as claimed in claim 2, wherein the positioning engagement portions return from the fitting locked condition checking tapered portions to a flat portion when the fitting position engagement portions are incompletely locked into the fitted condition lock portion.
Claim 8
Dependent Claim
75 words
A connector comprising: a connector housing having an initial position setting lock portion disposed in a positioning groove formed on a side surface of the connector housing; and a fitting operation lever pivotally disposed on the connector housing, said fitting operation lever having an engagement portion, wherein the connector housing and the fitting operation lever are set in an initial position set condition by engaging the engagement portion with the initial position setting lock portion.
Claim 9
Dependent Claim
75 words
A connector comprising: a connector housing having an initial position setting lock portion disposed in a positioning groove formed on a side surface of the connector housing; and a fitting operation lever pivotally disposed on the connector housing, said fitting operation lever having an engagement portion, wherein the connector housing and the fitting operation lever are set in an initial position set condition by engaging the engagement portion with the initial position setting lock portion.
Claim 10
Dependent Claim
22 words
A connector as claimed in claim 6, wherein the connector housing has guide notches for receiving driven pins of a mating connector.
Claim 11
Dependent Claim
21 words
A connector as claimed in claim 7, wherein the fitting operation lever has drive cam grooves for receiving the driven pins.
