A battery contact spring typically must perform two roles - to help provide pressure to hold batteries in place as well as to conduct electrical current from the batteries to the desired circuit. The force exerted by the spring on the battery or batteries often affects the electrical conductivity, especially where surface oxidation on the battery contacts may be present. Corrosion and oxidation, as well as the battery spring's suitability for specific soldering processes, should be considered during design.
Newcomb Spring will work with you to create an effective battery contact design for your application. With state-of-the-art equipment, a highly skilled team of spring-makers and our vast specialty material capabilities, our design assistance services can help save you time and cost on your battery springs and battery contacts.
Newcomb Spring produces battery springs and battery contacts using a wide array of materials, and manufacturers parts to meet your custom configurations. While Newcomb Spring facilities maintain an inventory of wire specially formulated for battery springs and battery contacts, other sizes and materials can also be supplied domestically, allowing us to respond quickly to your prototype and production requirements.
Materials used in the production of battery springs and battery contact components are most commonly made from the copper alloys, and nickel plated carbon steel.
Generally, materials with higher mechanical properties have lower electrical conductivity. Often they are used for battery contact manufacturing where cost is a major consideration and where the needed conductivity can be achieved with a pre-plated carbon steel, such as music wire, nickel coated or with a subsequent plating process. When high conductivity is required, as in military weapon applications and computers, the designer will want to consider battery contact materials with higher copper content, such as beryllium copper, phosphor bronze or spring brass. In certain applications, battery contacts and battery springs are sometimes plated in tin, silver or gold plated-remove as a subsequent operation, which increases conductivity even more.
As with all Newcomb Spring-produced parts, we can custom manufacture any battery contact or battery spring to fit your needs. As a trusted battery contact manufacturer, we have offered great prices, high quality and total customer satisfaction for more than a century.
