Description
SOLID WIRE TERMINAL LUG CONNECTOR
Background of the Invention Terminal lugs and other associated connector lugs have been used for years for providing a connection between a wire and a connecting member. Typically twisted multi-strand wire is used as it is relatively resilient and deformable upon squeezing or crimping laterally along the wire's longitudinal axis. A connection between the wire and the connector lug is usually made by crimping the connector around the multi-strand wire using a conventional crimping ~ool. The connection forms an electrically conductive path upon suitable deformation of the wire and the connector such that they mesh with one another It has been found that crimping a connector lug around a solid wire may not provide a reliable connection as deformation of the solid wire is minimal.
Summaxy of the Invention The problems associated with the prior art connectors can be overcome by providing a terminal lug having an integrally f~rmed wire wrap post which thereby provides a means of conveniently connecting a solid wire to the lug.
'~he problems associated with crimping are overcome by tightly wrapping the solid wire a number of times around the wire wrap post which is designed to bite into the wire when the edges of the post meet the wire. In addition, one or more barbs can be provided near the juncture of the wire wrap post and the lug for retaining the insulating housing around the connection.
Accordingly, one aspect of the invention, is to provide a screw terminal comprising a lead-e~d and a securing-end, the lead-end being integrally formed with the ;
securing-end and suitable for receiving the wire-wrap lead, and the securing-end forming a terminal lug connector.

Detailed Description of the Preferred Embodiment In figure 1, a prior art terminal lug is shown and is comprised o~ a securing end 10 for connection to a screw terminal. The terminal lug has an integrally formed collar 11 for crimping t~isted wires 12. The wires 12 have a housing 13 which must be stripped off before they are crimped to the lug. Upon application of lateral force by a crimping tool on the collar 11, the collar deforms and separates the twi~ted wixes into essentially two bundles of twisted wires which become tightly bound by the collar 11.
The terminal lug of the present invention is shown in figures 2a and 2b. It is comprised of a securing-end 20 integrally formed with a lead-end 23. At the ~uncture of the lead-end 23 and the securing-end 20 there is ~hown a neck portion 21. The terminal lug can be bent at the neck portion 21 if it is required. A barbed portion 22 is provided for engaging an insulating housing. As shown in figure 2b, the lug is generally flat with the neck portion 21 being ;
integrally formed with the barbed portions 22 and securing-end 20. The lead-end 23 is provided with edges extending longitudinally which are designed to bite into the wire upon being wrapped thereon. The barbed portions 22 extend laterally therefrom with sharp edges pointing generally away from said lead-end 23. The securing-end 20 is provided with retaining lips 25 to retain the terminal lug to a screw if the screw becomes loose.
In figure 3, there is shown a wire lead having an insulated portion 27 and a stripped portion 24. The stripped portion is tightly wrapped to the lead-end 23 forming a ,.. .... .. ... ., .. . . ,.- -.. - . . : : .: : . , . , . . :

conductive path therebetween. A housing 26 is shown and provides insulation to the stripped wire wrapped portion 24.
The barbed portion 22 engages the housing and prevents the housing from inadvertently slipping off the lead-end 23.
The terminal lug arrangement may be formed with a flat spade-type securing-end instead of the screw type securing-end 20 shown in figure 2. While a preferred embodiment has been shown and described, it will be understood that there is no intent to limit the invention by such disclosure but, rather, it is intended to cover all modi~ications and alternate construction~ falling within the spirit and scope of the invention as defined in the appended claims .

The barbed portions 22 extend laterally therefrom with sharp edges pointing generally away from said lead-end 23. The securing-end 20 is provided with retaining lips 25 to retain the terminal lug to a screw if the screw becomes loose.
