ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a coupler. and more particularly to a fuse coupler combination.
2. Description of the Prior Art
U.S. Pat. No. 5,362,253 to Lin et al., U.S. Pat. No. 5,440,073 to Lin et al., U.S. Pat. No. 5,573,423 to Lin et al. U.S. Pat. No. 5,573,433 to Lin et al., and U.S. Pat. No. 5,599,777 to Liang disclose various kinds of typical cable mounting devices or cable couplers having an electric wire coupled to a conductive connector without additional fasteners. However, the conductive connector is also required to be secured or attached to the other supporting casing or fuse receiving housing with the other fasteners, such that the other tools and fasteners are also required for securing the conductive connector to the other supporting casings or housings.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional cable couplers.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a fuse coupler combination for securing the electric wire to the fuse without additional tools.
In accordance with one aspect of the invention, there is provided a fuse coupler combination comprising a fuse coupler including a first end having a socket provided thereon, and including a second end having a chamber and an inner thread formed therein, a fuse member including a first end engaged into the socket, a control ferrule including an outer thread formed thereon for threading with the inner thread of the fuse coupler and for securing the control ferrule to the second end of the fuse coupler, a barrel rotatably secured to the control ferrule and received in the chamber of the fuse coupler, and an electric wire including a first end received in the chamber of the fuse coupler and engaged between the barrel and the fuse coupler, for allowing the first end of the electric wire to be secured between the barrel and the fuse coupler by the control ferrule.
The control ferrule includes a bore formed therein for receiving the electric wire, and includes a peripheral rib extended radially inward of the bore thereof for defining a peripheral shoulder therein, the barrel includes a bore formed therein for receiving the electric wire and includes a first end bent relative to the barrel and engaged with the peripheral rib of the control ferrule for rotatably securing the barrel to the control ferrule.
The first end of the barrel includes a cylindrical member having a reduced diameter relative to the barrel for defining a peripheral shoulder between the barrel and the cylindrical member and for engaging with the control ferrule.
A housing is further provided for receiving the fuse member and the fuse coupler, and a cap is engaged onto the housing and engaged with the control ferrule for retaining the fuse member and the fuse coupler and the control ferrule in the housing.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow. with appropriate reference to accompanying drawings.
