Technical Field

Background

An electrical connector (or terminal) is a device that is often used in the electrical field. The existing electric connector comprises a first insulating shell and a second insulating shell (or called cover plate) which are assembled together, wherein a wiring hole for inserting a conducting wire is formed in the first insulating shell, an electric conductor is arranged on the second insulating shell, a clamping elastic sheet is further arranged in a space formed after the first insulating shell and the second insulating shell are assembled, and one end of the clamping elastic sheet is fixed on the electric conductor. When wiring is needed, an external tool is utilized to apply downward force to the clamping elastic sheet in a direct or indirect mode, so that the clamping elastic sheet is elastically deformed after being stressed to move downwards, then the electric lead penetrates through the wiring hole and a space formed by the clamping elastic sheet after moving downwards, after the downward force applied to the clamping elastic sheet is relieved, the clamping elastic sheet moves upwards under the elastic restoring force to clamp the electric lead, and therefore the electric connection between the connected electric lead and the electric conductor is achieved.

However, the existing electrical connector has some problems: when a conductive wire, especially a conductive wire with a small wire diameter, needs to be connected into the electric connector, the clamping spring in the electric connector must be opened by an external tool, and then the wire end of the conductive wire is clamped between the clamping spring and the conductive body, which results in complex wire connection operation and reduced wire connection efficiency.
