Banana and Tip Connectors encompass a variety of electrical connection jacks, plugs, and other devices for use in electrical and electronic systems as reliable connection points for power or signal leads. The type known as 1437502-7 is a banana plug which provides a secure connection between power sources or wires and instrumentation.

Applications

Banana and tip connectors, and the specific 1437502-7 model, are frequently employed in light and industrial applications such as instrument panels, test equipment, in-place testing, and electronic applications for interconnects. These versatile connectors are used for a wide range of electrical wiring applications in the commercial, industrial, and military sectors. They are also popular for both internal and external equipment wiring. Common applications include power supplies, switches, motors, lights, amplifiers, and other DIY projects.

Working Principle

The 1437502-7 model comprises a male 2-pin plug with one plus and one minus device connector. This allows the banana plug to fit securely into a standard banana jack. The banana plug is designed to accept a 1/4” female banana connector, and will provide a secure hold on any conductor ranging up to 1/4” in diameter. Once the wire is connected to the jack connector, the gold-plated steel wire and pin provide superior conductivity and reliable contact performance. This provides a low-resistance connection for optimal current transfer, and eliminates any potential for outside interference or electrical noise.

The 1437502-7 model also includes a spring-loaded, nickel-plated brass pin that rises up to meet the male contact. Secure engagement is easily achieved with a single, intentional lift of the pin, which ejects the male contact securely into the banana jack connector. Because the entire unit is composed of metal, this banana plug keeps contact points reliably sealed. Its two-piece construction also contains corrosion-resistance black zinc plating that enhances contact quality and increases its holding capacity.

The 1437502-7 model is built to provide a firm and secure fit into banana jacks. The housing material is molded from high-grade polycarbonate that adds strength and durability. The oversized external connection pins are threaded, which ensures that the male connector is firmly secured into any female banana jack it is inserted into.

Since the 1437502-7 banana plug is constructed to meet safety requirements, it is suitable for use in most industrial, electrical, and electronic settings. It also complies with the regulations established by the UL, CSA, and RoHS standards, making it a robust and safe choice for many projects.
