Problems solved by technology

This technology, while more compact, has serious drawbacks: (1) Due to the small size of the actuator pin, closure of the terminal still requires a tool (for example, a screwdriver with a slotted end); and (2) it is only suitable for Multi-wire bundled flexible conductors, therefore not suitable for preparing conductors with insulating crimped ferrules (a solution favored by manufacturers of wiring harnesses for electrical panels) or single-pole conductors—whether solid or multi-wire bundled— , these conductors are still widely used in many countries for the wiring of fixed electrical equipment

Abstract

Electrical connecting device including an insulating body with parallel longitudinal seats and, respectively adapted to accommodate a connecting element with spring terminal and an actuator pin with profile cam facing a spring of the terminal to cause the opening and closing of said terminal by means of sliding in the corresponding seat, said spring being a ring-shaped spring with a curved lower portion, a back ascending portion engageable by a protruding portion of said cam profile of the actuator pin and an upper portion with a slot adapted to receive at least one electrical conductor, characterized in that in said actuator pin a hollow seat delimited by two lateral walls is provided adapted to receive the aforementioned ascending leg of the spring-shaped ring in condition of maximum extroversion of the spring, i.e. upon empty closed terminal.

Description

Technical field [0001] The invention relates to an electrical connection device with a spring connection element, in particular an electrical connection terminal for the connection of one or more electrical conductors, the electrical connection terminal being equipped with a compact actuator. In particular, without excluding other embodiments of the present invention, the electrical connection element is in the form of an electrical contact element-a male (plug) element or a female (socket) element. [0002] In particular, the electrical connection device in question may also be adapted to be accommodated in an insulating body of a multi-pole connection device such as an electrical connector for connecting types with multiple wires (flexible connectors) The electrical conductor or single wire type (rigid or flexible, but prepared with crimped metal ring terminals). Background technique [0003] Electrical connection elements and electrical connection terminals suitable for connect...
