Abstract
Abstract A connector including at least two connector blocks, first connector block and second connector block, which may be employed to interconnect fiber optic cables or electrical cables. A pair of frame-like lugs on a housing of the first connector block are engageable with a pair of flexible arms on a housing of the second connector block to couple the two connector blocks to each other. A housing of one of the connector blocks is provided with members which are resiliently deformable when engaged with part of a housing of the other connector block. When sliders which are also furnished with on the first connector block are engaged with the flexible arms of the second connector block, the connector blocks are uncoupled from each other due to restoring forces exerted by the resilient deformable members.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
A connector for coupling and uncoupling a plurality of connector blocks, comprising: a first connector block having a housing which is provided, on a pair of opposite walls thereof, with a pair of outwardly extending lugs and a pair of sliders which are individually movable along said opposite walls; a second connector block having a housing which is provided, on a pair of opposite walls thereof, with a pair of frame-like flexible arms which are respectively engageable with the lugs on the first connector block; and resilient deformation means for exerting a restoring force to cancel a coupled condition between the first and second connector blocks when the sliders of the first connector block are brought into engagement with the flexible arms of the second connector block, said resilient deformation means being resiliently deformed in contact with part of one of the first and second connector blocks when the first and second connector blocks are coupled with each other with the lugs and the flexible arms engaged with each other.
Claim 2
Dependent Claim
170 words
A connector for coupling and uncoupling a plurality of connector blocks, comprising: a first connector block having a housing which is provided, on a pair of opposite walls thereof, with a pair of outwardly extending lugs and a pair of sliders which are individually movable along said opposite walls; a second connector block having a housing which is provided, on a pair of opposite walls thereof, with a pair of frame-like flexible arms which are respectively engageable with the lugs on the first connector block; and resilient deformation means for exerting a restoring force to cancel a coupled condition between the first and second connector blocks when the sliders of the first connector block are brought into engagement with the flexible arms of the second connector block, said resilient deformation means being resiliently deformed in contact with part of one of the first and second connector blocks when the first and second connector blocks are coupled with each other with the lugs and the flexible arms engaged with each other.
Claim 3
Dependent Claim
23 words
A connector as claimed in claim 1, in which the housings of the first and second connector blocks are individually made of plastic.
Claim 4
Dependent Claim
33 words
A connector as claimed in claim 1, in which the opposite walls of the housing of the first connector block are individually formed with slots, the sliders being respectively received in said slots.
Claim 5
Dependent Claim
39 words
A connector as claimed in claim 1, in which the opposite walls of the housing of the first connector block are individually formed with channels each having a trapezoidal cross-section, the sliders being respectively coupled in said trapezoidal channels.
Claim 6
Dependent Claim
64 words
A connector as claimed in claim 4, in which a wall of the housing of the second connector block which neighbors the opposite walls which are provided with the flexible arms is at least partly machined to have an opening, at least part of the housing of the first connector block being inserted through said opening into the housing of the second connector block.
Claim 7
Dependent Claim
50 words
A connector as claimed in claim 5, in which each of the flexible arms is formed by at least two slits each extending from the opening of the second connector block, and a through opening interposed between said slots to receive one of the lugs of the first connector block.
Claim 8
Dependent Claim
55 words
A connector as claimed in claim 6, in which the resilient deformation means comprises a leaf spring integral with a front wall of the housing of the first connector block which neighbors the opposite walls, said leaf spring extending from said front wall while being inclined from a fixed end to a free end thereof.
Claim 9
Dependent Claim
37 words
A connector as claimed in claim 6, in which the resilient deformation means comprises a leaf spring which is formed integrally with and projected from one of inner walls of the housing of the second connector block.
Claim 10
Dependent Claim
45 words
A connector as claimed in claim 8, in which the leaf spring functioning as the resilient deformation means extends from one of the inner walls of the housing of the second connector block while being inclined from a fixed end to a free end thereof.
Claim 11
Dependent Claim
50 words
A connector as claimed in claim 8, in which at least one pair of the leaf springs are provided to function as the resilient deformation means, said leaf springs individually extending substantially linearly from one of the inner walls of the housing of the second connector block toward the opening.
Claim 12
Dependent Claim
58 words
A connector as claimed in claim 10, in which a front wall of the housing of the first connector block adjacent to the opposite walls is provided with a recess having inclined wall portions which bend the at least one pair of leaf springs of the second connector block when the first and second connector blocks are coupled.
Claim 13
Dependent Claim
32 words
A connector as claimed in claim 6, in which the resilient deformation means comprises a coil spring disposed in a bore which is contiguous with the opening of the second connector block.
