Embodiment Construction

[0024] The present invention is a terminal having a bend from 10-120 degrees for terminating wires to a terminal block with a ferrule or pin connection. Typically, the ferrule or pin end is connected to the terminal block, while the opposite end includes an insulating sleeve for receiving the stripped end of the stranded wire. In applications where space is limited, bends in the terminals allow them to be installed into the terminal block from a variety of angles.

[0025] Ferrule terminals can be bent up to 120 degrees and include strain relief holes that help thin-walled ferrules bend without creasing or damaging the outer wall. As used herein, the term "ferrule" refers to a cylindrical tube or sleeve made of a conductive metal such as copper and having a thin outer wall. Stranded wire is inserted through the insulating sleeve into the ferrule. Push the stripped end through until it extends around the bend in the ferrule and into the second leg of the ferrule (i.e., the op...

Abstract

A ferrule or pin terminal is provided with a bend to facilitate terminations in confined or restricted spaces and provides consistency and uniformity. The ferrule terminal embodiment of the present invention includes a ferrule portion and a barrel portion. The ferrule portion includes a cylindrical wall, a first end, a second end, a longitudinal axis and a stress relief aperture. The ferrule portion is bent along the longitudinal axis to form a bend. The pin terminal embodiment of the present invention includes a solid pin portion and a barrel portion. The solid pin portion includes a body, a first end and a second end and has a longitudinal axis. The first end of the solid pin portion is angularly disposed from the second end. In both embodiments, the barrel portion includes a cylindrical body having a first end adapted to receive an electrical wire and a second end connected to the second end of the ferrule.

Description

[0001] This application claims priority to Provisional Application Serial No. 60 / 994,069, filed September 17, 2007, which is hereby incorporated in its entirety. technical field [0002] This invention relates to connectors for terminating wires. In particular, the present invention relates to 90 degree connectors for terminating wires in confined spaces. Background technique [0003] Ferrule and pin terminals are commonly used to ensure a reliable electrical connection when terminating stranded control wires in screw clamp type terminal blocks. The main benefit of these terminals is that they prevent strand fraying and breakage that can occur when wires are terminated directly under terminal block screw clamps. In addition, the terminals may be insulated to provide protection from wire stresses due to bending and / or vibration while facilitating insertion of the wires into the terminal strip clips. [0004] The current trend is that almost all commercial and industrial pro...
