Abstract
Abstract According to the present invention, cam grooves are formed in a lower surface of a rotation plate of a cam member, and are disposed symmetrically with respect to a rotation shaft. A rotation retaining plate is mounted on a distal end of the rotation shaft. A pair of housings have cam follower pins, respectively, which are engaged in the cam grooves, respectively. One housing has a pin guide groove which guides the rotation shaft and the cam follower pin. A flexible lock member having a lock release projection is provided at an introduction groove of one cam groove in the rotation plate. Upon the initial fitting of the pair of housings, the cam follower pin is engaged with the lock release projection to release the locking of the rotation plate by the flexible lock member, thereby allowing the angular movement of the cam member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
200 words
A low insertion/withdrawal-force connector comprising: a cam member including a rotation plate, a rotation shaft provided to a lower surface of said rotation plate, said rotation shaft having a retaining plate at a distal end thereof, a pair of cam grooves provided to a lower surface of said rotation plate, said cam grooves being continuous respectively with introduction grooves and disposed symmetrically with respect to said rotation shaft; a mail housing having a first cam follower pin; a female housing in which said male housing is movably fitted, said female housing having a second cam follower pin and a pin guide groove for guiding said first cam follower pin and said rotation shaft; and means for locking said male housing and said female housing when said male housing is completely fitted in said female housing, wherein when said cam member is angularly moved in an initial fitting condition of said mail and female housings in which said first and second cam follower pins are respectively engaged in said pair of cam grooves, said cam member moves toward an inner end of said pin guide groove, and also said mail and female housings are moved each other toward said rotation shaft.
Claim 2
Dependent Claim
117 words
A low insertion/withdrawal-force connector according claim 1, wherein said locking means includes: a lock member provided in said introduction groove of one of said cam grooves, said lock member having a lock piece and a lock release projection; and a lock hole provided to said female housing, wherein said first cam follower pin is engaged with said lock release projection to release the engagement between said lock member and said female housing at the time of the initial fitting of said male and female housings, thereby allowing the angular movement of said cam member, and said lock piece is engaged in said lock hole at the time of the complete fitting of said male and female housings.
Claim 3
Dependent Claim
21 words
A low insertion/withdrawal-force connector according to claim 1, further comprising a thumbpiece provided to an upper surface of said rotation plate.
Claim 4
Dependent Claim
105 words
A low insertion/withdrawal-force connector according to claim 3, wherein said locking means includes: a pair of lock pieces provided to said thumbpiece; and a pair of lock holes provided to said female housing, wherein said thumbpiece is disposed in a first position at the time of the initial fittings of said male and female housings, thereby allowing the angular movement of said cam member, and said thumbpiece is push down in a second position in such a manner that said pair of lock pieces are engaged in said pair of lock holes at the time of the complete fitting of said male and female housings.
Claim 5
Dependent Claim
64 words
A low insertion/withdrawal-force connector according to claim 3, further comprising a U-shaped lock wall and a half-fitting prevention guide wall which are provided on said female housing, wherein said thumbpiece is slidably provided to said rotation plate and said thumbpiece is slidingly moved so as to be engaged in said U-shaped lock wall when said male housing is completely fitted in said female housing.
Claim 6
Dependent Claim
266 words
A low insertion/withdrawal-force connector comprising: a cam member including cam grooves which are continuous respectively with introduction grooves, are provided at a lower surface of a rotation plate, and are disposed symmetrically with respect to a rotation shaft, and a rotation retaining plate provided at a distal end of said rotation shaft; a pair of housings which are fitted together and disengaged from each other by angularly moving said cam member, said pair of housings having cam follower pins, respectively, which are engaged in said two cam grooves of said cam member, respectively, one of said pair of housings having a pin guide groove which guides said cam follower pin of the other housing and said rotation shaft of said cam member, wherein when said cam member is angularly moved in an initial fitting condition of said pair of housings in which said cam follower pins of said housings are engaged respectively in said pair of cam grooves, said cam member moves toward an inner end of said pin guide groove, and also said pair of housings are moved toward each other toward said rotation shaft of said cam member; and a flexible lock member having a lock release projection is provided in said introduction groove of one of said cam grooves in said rotation plate, wherein said cam follower pin of the other housing is engaged with said lock release projection to release the engagement between said flexible lock member and said one housing at the time of the initial fitting of said pair of housings, thereby allowing the angular movement of said cam member.
Claim 7
Dependent Claim
233 words
A low insertion/withdrawal-force connector comprising: a cam member including cam grooves which are continuous respectively with introduction grooves, and are provided at a lower surface of a rotation plate, and are disposed symmetrically with respect to a rotation shaft, and a rotation retaining plate provided at a distal end of said rotation shaft; a pair of housings which are fitted together and disengaged from each other by angularly moving said cam member, said pair of housings having cam follower pins, respectively, which are engaged in said two cam grooves of said cam member, respectively, one of said pair of housings having a pin guide groove which guides said cam follower pin of the other housing and said rotation shaft of said cam member, wherein when said cam member is angularly moved in an initial fitting condition of said pair of housings in which said cam follower pins of said housings are engaged respectively in said pair of cam grooves, said cam member moves toward an inner end of said pin guide groove, and also said pair of housings are moved toward each other toward said rotation shaft of said cam member; an angular movement-effecting thumbpiece withdrawably or slidably mounted on an upper surface of said rotation plate; and lock means provided between said one housing and said thumbpiece so as to lock said thumbpiece when said pair of housings are completely fitted together.
