In an electrical construction, grounding refers to a work for connecting a part of an electrical circuit or electrical equipment to the ground using a conductor.

Since the ground maintains approximately the same potential, circuit parts connected to the ground through a low-resistance conductor may be considered to have a uniform potential value, and a conductor connecting an electric device to the ground is called a grounding conductor or grounding wire.

The grounding wire is used with an insulating coating formed on the wire for the purpose of safety in processing. In the underground, the grounding wire is used in the form of a bare wire without the insulation coating for the purpose of close contact with the ground. The grounding wire can be used as a single wire when the size is small, however, if the size becomes large, several strands of wires are twisted and used in the form of a stranded wire.

A conventional grounding wire installed in the ground is composed of a single stranded wire, so an inner surface of the stranded wire does not come into contact with the ground, so it is difficult to lower the grounding resistance value.

Therefore, there are provided a flat array grounding wire and a grounding method using the same, in which the flat array grounding wire is configured to lower the grounding resistance value by greatly increasing the surface area in contact with the ground by arranging the grounding wires used for a grounding work in an electrical construction on a flat plane, so that the construction cost can be reduced as the grounding resistance value is lowered.

The invention provides an easy lock connector with unlock structure applied to a flat wire and a circuit board. The flat wire has a notch and a ground wire on the two sides of a head end respectively. The easy-lock connector includes an upper housing, a lower housing, a rubber core and a terminal. After the notch of the flat wire is buckled by a stopper of the lower housing, by pressing a pressing member of the upper housing, the pressing member applies an external force to an elastic member of the lower housing to deform the elastic member. An extension arm of the lower housing is linked by the elastic member to cause the stopper to act in one direction so as to release the state of the stopper from locking the gap. In another embodiment, the easy-lock connector can also achieve an electromagnetic shielding effect by adding a shielding iron shell.
