Removing rust from electrical leads is necessary for good contact of the leads to the electrical component to which you are connecting the leads. Lead contact can make the difference between a component that works and one that doesn't. Be careful, however, when removing rust from electrical leads so that you don't damage the wire, or the lead clip or retaining connector on the end of the lead.
Lead wire terminal connectors with flat contact surfaces especially require tool tightening,because of their large contact areas with the terminal post components. Accordingly, there have been a number of lead wire terminal connector designs with upstanding ridges or the like, which greatly reduce the area of contact resulting in highly concentrated electrical contact forces Examples include the lead wire terminal disclosed in United Kingdom patent application No. 2,183,404, and U.S. Pat. Nos. 3,861,780 and 1,608,578. However, these disclosed embodiments still require the electrical connection be made through essentially rigid mating components. Excessive tightening is therefore often still required. Further, these disclosed designs do nothing to maintain the contact over extended periods of time.
An electrical lead wire terminal connector 10 is shown in FIG. 1 secured to an insulated electrical wire lead 11 preparatory to be joined to a post connector 12. Post connector 12 comprises a stem 13, often provided with a cross bore 14, and a finger tightenable threaded cap 15 on one of its ends. The electrical wire 11 is often connected by insertion through bore 14, with cap 15 then finger tightened thereupon to provide electrical contact between wire, post and cap. However, terminal connector 10 is configured to make the necessary electrical contact with the flat surface 16 of post connector shoulder 17 and also with opposing metallic base 18 of finger cap 15. (FIG. 2) A portion of post 12 below shoulder 17 is used for installation into a terminal board or the like, not shown, and varies considerably from one application to another.
