Description

Wiring device Technical Field The invention relates to the field of electrical measurement, in particular to a wiring device. Background In the wiring process of electrical measurement, crocodile clips (also called spring clips or test clips) are widely used due to large openings and strong clamping force, but when the crocodile clips are applied to an electric energy meter with compact structure and dense wiring terminals, a plurality of defects exist: Firstly, the electric energy meter binding post size is various, and the crocodile presss from both sides only has few general specification, is difficult to compromise from miniature to large-scale different terminals, to the terminal of uncomfortable, the crocodile presss from both sides is difficult to provide effective centre gripping, very easily becomes flexible and drops under the test wire tractive, leads to signal interruption, data misalignment, needs to connect repeatedly, seriously influences check-up efficiency and result reliability. Secondly, electric energy meter binding post arranges densely, especially three-phase electric energy meter, and traditional crocodile presss from both sides bulkiness, and its insulating housing only covers the handle generally, can't carry out effective isolation to the metal spring arm, and the metal spring arm exposes completely outside, and when operating in narrow space, the naked metal of adjacent crocodile presss from both sides is very easy to touch each other because of operation or wire rod dead weight, causes interphase or short circuit to ground in the twinkling of an eye, produces electric arc, seriously threatens equipment and personnel's safety.
