Abstract
Abstract A cable clamp of the present invention comprises a base having a fixing portion on the lower surface, a flat clamp rockingly connected to the base, and a means for locking a distal end of the flat clamp to the base engageably or disengageably. The cable clamp retains electric wires between the base and the flat clamp. The locking member comprises a plate-shaped protrusion provided on the flat clamp or the base and a retaining protrusion formed with the outer surface thereof. A resilient retaining member is protrudingly provided on the flat clamp opposite the plate-shaped protrusion or the base and has a hole for engaging with the retaining protrusion. An engaging member is protrudingly provided on the same surface with the resilient retaining member in parallel and engaging with an inner surface of the plate-shaped protrusion. Further, a notched portion formed with a distal end of the resilient retaining member faces the engaging member. Therefore, the cable clamp can easily carry out unlocking without any unlock levers and offers not only a simple but a secure locking mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
242 words
A cable clamp comprising: (a) a base having an upper surface, a lower surface, and a fixing portion on its lower surface; (b) a flat clamp rockingly connected to said base; and (c) a pair of locking members, said pair of locking members locking a distal end of said flat clamp to an end portion of said base engageably or disengageably, in use retaining electric wires between said base and said flat clamp in the locked state, said pair of locking members comprising: (i) a plate-shaped protrusion provided on said flat clamp or said base, said plate-shaped protrusion having an inner surface and an outer surface; (ii) a retaining member formed on the outer surface of said plate-shaped protrusion; (iii) a resilient retaining member protrudingly provided on the other of said flat clamp or said base opposite said plate-shaped protrusion, said resilient retaining member having a hole for engaging said retaining member; (iv) an engaging member protrudingly provided on said the other of said flat clamp or said base in parallel to said resilient retaining member, said engaging member being sized, shaped, and positioned to make planar contact with the inner surface of said plate-shaped protrusion in the locked state; and (v) a notched portion formed on the distal end of said resilient retaining member, said notched portion being sized, shaped, and positioned so that it can be manipulated manually to disengage said retaining member from said hole in said resilient member.
Claim 2
Dependent Claim
242 words
A cable clamp comprising: (a) a base having an upper surface, a lower surface, and a fixing portion on its lower surface; (b) a flat clamp rockingly connected to said base; and (c) a pair of locking members, said pair of locking members locking a distal end of said flat clamp to an end portion of said base engageably or disengageably, in use retaining electric wires between said base and said flat clamp in the locked state, said pair of locking members comprising: (i) a plate-shaped protrusion provided on said flat clamp or said base, said plate-shaped protrusion having an inner surface and an outer surface; (ii) a retaining member formed on the outer surface of said plate-shaped protrusion; (iii) a resilient retaining member protrudingly provided on the other of said flat clamp or said base opposite said plate-shaped protrusion, said resilient retaining member having a hole for engaging said retaining member; (iv) an engaging member protrudingly provided on said the other of said flat clamp or said base in parallel to said resilient retaining member, said engaging member being sized, shaped, and positioned to make planar contact with the inner surface of said plate-shaped protrusion in the locked state; and (v) a notched portion formed on the distal end of said resilient retaining member, said notched portion being sized, shaped, and positioned so that it can be manipulated manually to disengage said retaining member from said hole in said resilient member.
Claim 3
Dependent Claim
26 words
A cable clamp as set forth in Claim 1, wherein said resilient retaining member has a stepped portion for guiding said retaining member into said hole.
Claim 4
Dependent Claim
23 words
A cable clamp as set forth in claim 1, wherein said base and said flat clamp are connected via a thinner connecting portion.
Claim 5
Dependent Claim
20 words
A cable clamp as set forth in Claim 1, wherein said resilient retaining member extends longer than said engaging member.
Claim 6
Dependent Claim
38 words
A cable clamp as set forth in claim 1, wherein a notched portion is formed in the inner portion of said plate-shaped protrusion and said engaging member is sized, shaped, and positioned to mate with said notched portion.
Claim 7
Dependent Claim
38 words
A cable clamp as set forth in claim 1, wherein a surface of said retaining member engages said notched portion formed on the distal end of said resilient retaining member and slidingly locks it to the surface thereof.
