Abstract

A wire connection terminal structure includes a leaf spring, a conductive plate and a fixing frame framing and connecting with the leaf spring and the conductive plate. The conductive plate is formed with a base section assembled with the fixing frame. The leaf spring is formed with an elastic swingable holding section extending to a position in contact with the base section. The holding section and the base section define therebetween an elastic holding mouth. An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.
