Patent attributes
An electric cord retention device includes a base, at least one cord hold-down member, and at least one lid, which together receive and retain an electric cord. The base has a top forming a cord accommodation slot and a coupling portion. Two conductor pieces are received and fixed in the cord accommodation slot and has sharp tips located in the cord accommodation slot. The coupling portion is arranged adjacent to the cord accommodation slot. The cord is positioned in the cord accommodation slot and is depressed down by the cord hold-down member that is fit into the cord accommodation slot and positioned above the cord. The lid is tightened to the coupling portion by means of threading engagement, whereby rotation of the lid with respect to the coupling portion causes the cord hold-down member to move downward and apply a force to the cord against the sharp tips, making the sharp tips piercing into the cord to establish electric connection therebetween.
