Such an electrical connection terminal includes a type that is interposed in a circuit board (for example, a PC circuit board) (for example, CN 102204015 A "Electrical Connection Terminal", DE 29915515 U1, EP 2325947 A1, etc.), and an electrical connection terminal The type of the grounded track (or conductive track) that is aligned to form a common grounding device for an electrical or mechanical device to derive the residual voltage or static electricity of those machines (eg, German DE 20 2008 015 306 U1) US 2013/0143433 A1 "CONNECTION TERMINAL", US 2014/0127932 A1 "ELECTRICAL CONNECTION TERMINAL", DE 10 2012 009 286 A1, US 5362259 "GROUND CONDUCTOR TERMINAL" and other patents), provides typical Example.

Such an electrical connection terminal (or rail type electrical connection terminal) generally includes an insulative housing; the housing has an entry hole for allowing the lead to be inserted into the interior of the housing. The housing also defines a chamber for fitting a plate-like conductive support (or conductive member) and a metal dome to cause the metal dome and the conductive member to press the wire inserted into the housing to form a contact or electrical connection. The electrical connection or contact state of the wire and the metal dome and the conductive member can be released unless the person operates other tools to push the metal dome into the housing.
