Abstract A spring locking device prevents any disconnection of connected female and male connector members of a connector. The locking device includes two pairs of bearings provided on both ends of a mounting flange of one connector member and locking members having support pins rotatably supported in the bearings. Each of the locking members is made of a springy wire and includes two parallel legs having lower ends outwardly bent, and support pins continuous to the lower ends to provide bent corners therebetween. When the locking members are mounted in the bearings, the bent corners are positioned inside of the bearings and in contact with bottoms of the bearings, and the support pins are in contact with semicircular edges of the bearings and extend therefrom out of the bearings on sides opposite to those of the legs. The locking device can prevent the support pins from removing from the bearings in a reliable manner with the aid of the particularly formed locking members without using removal preventing members.
A spring locking device for a connector including a female connector member and a male connector member, said spring locking device including two pairs of bearings arranged on both ends of a mounting flange of one connector member, respectively, each of the bearings having openings in directions substantially perpendicular to longitudinal directions of the one connector member and having a semicylindrical inner surface, and locking members made of a springy wire, each locking member having two legs spaced in parallel with each other and two support pins bent outwardly relative to the legs and rotatably supported in said one pair of bearings, thereby locking the two connector members by turning the locking members into slits formed in the other connector member after the two connector members are connected, wherein each of the locking members comprises the legs having lower ends outwardly bent and the support pins continuous to the lower ends and having bent corners between the lower ends and the support pins, and said bent corners are positioned inside of the bearings and in contact with bottoms of the bearings and said support pins are in contact with semicircular edges of the bearings and extend therefrom out of the bearings on sides opposite to those of the legs when the locking members are mounted in the bearings.

A spring locking device for a connector including a female connector member and a male connector member, said spring locking device including two pairs of bearings arranged on both ends of a mounting flange of one connector member, respectively, each of the bearings having openings in directions substantially perpendicular to longitudinal directions of the one connector member and having a semicylindrical inner surface, and locking members made of a springy wire, each locking member having two legs spaced in parallel with each other and two support pins bent outwardly relative to the legs and rotatably supported in said one pair of bearings, thereby locking the two connector members by turning the locking members into slits formed in the other connector member after the two connector members are connected, wherein each of the locking members comprises the legs having lower ends outwardly bent and the support pins continuous to the lower ends and having bent corners between the lower ends and the support pins, and said bent corners are positioned inside of the bearings and in contact with bottoms of the bearings and said support pins are in contact with semicircular edges of the bearings and extend therefrom out of the bearings on sides opposite to those of the legs when the locking members are mounted in the bearings.
Claim 3
Dependent Claim
51 words
A spring locking device for a connector as set forth in claim 1, wherein said mounting flange is provided with stopper members, said stopper members having heights from the mounting flange and facing to openings of the bearings in opposition to each other and positioned in the proximity of the openings.
Claim 4
Dependent Claim
