Spring-clip terminal
Spring-clip terminals are push-to-connect electrical connectors commonly used for external speaker connections on consumer televisions and audio equipment. They provide a quick, tool-free connection for bare speaker wire.
Overview
Spring-clip terminals consist of a spring-loaded lever or tab that is pressed to open a hole or slot, into which bare wire is inserted. Releasing the lever clamps the wire securely in place. They are typically found in pairs (left/right) or sets of four (left/right with +/−), often housed in a recessed panel on the rear of the set.
Compared to binding posts, spring-clip terminals are simpler and more compact but generally accept only bare wire (not banana plugs or spade connectors) and are rated for lighter-gauge wire.
Common Uses
- External speaker connections on consumer CRT televisions
- Compact audio equipment speaker outputs
- Budget and mid-range AV receivers
