Banana Jack

Description

4mm Standard Male Banana Plug (Solderless/Screw-Type) The 4mm Male Banana Plug is one of the most widely used connectors in the electrical testing, audio, and educational sectors. Named for its distinctively bowed, spring-metal leaf prong that resembles a banana, this plug expands slightly inside a matching 4mm female jack to create a high-friction, low-resistance electrical connection. This specific version features an open-screw design, allowing users to attach raw speaker or test wires in seconds without a soldering iron. Key Features Connector Type: 4mm Male Banana Plug. Solderless Installation: Features a side-entry or bottom-entry set screw that clamps down firmly onto stripped wire leads, securing them without requiring solder. Spring-Loaded Contact: Outfitted with a high-tension metal leaf basket collar that ensures an exceptionally tight fit and prevents accidental disconnects. Color-Coded Shroud: Housed in an insulated plastic or flexible PVC sleeve, universally colored Red (Positive) and Black (Negative) for safe, instant polarity matching. Stackable (Select Models): Many 4mm plugs feature a female 4mm jack drilled straight into the rear of the plug housing, allowing multiple patch cables to be stacked on top of a single terminal port. Compatibility Guide This universal plug interfaces with standard testing arrays, high-end audio setups, and low-voltage bench power lines. 1.
