Abstract: An alligator clip with an improved structure including a first and a second clip members connected to each other by a pivot pin is disclosed. A resilient member is installed on the pivot pin with two opposite ends in contact against the interior surfaces of the first and second members. The front ends of the first and second clip members are used to clip the positive/negative electrode of the car battery. A tuck formed from the bottom end of the first clip member, including a through hole each on two opposite ends to wrap a power cord so that two through holes are aligned to receive a fixture to secure the tuck on the power cord.

Abstract: A power distribution outlet having a connector body, a distributing block, an insulation plate, a fuse, and an insulation housing is disclosed. The connector body is connected to the electrode of the battery. The distributing block has a plurality of wire inlets for connecting a plurality of power cords. The connector body and the distributing block are fixed on an insulation plate and insulated to each other thereby. The fuse electrically connects the connecting block and the distributing block, which are enclosed in the insulation housing. The above structure allows multiple power cords to be conducted with the battery at the same time, while the fuse can be easily inspected and replaced to protect the electronic products connected to the power cords, and the structure is easily fabricated.

Abstract: A fuse coupler device includes one or two fuse couplers received in a housing and each having a socket formed on one end for engaging with a fuse member, a control ferrule includes an outer thread for threading with the fuse coupler, and a barrel is rotatably secured to the control ferrule. An electric wire has one end secured between the barrel and the fuse coupler by the control ferrule without additional fasteners and tools. The fuse member and the fuse coupler may be received in a housing, and a cap may be threaded to the housing for retaining the fuse member in the housing.
