The described first electric current bridge is provided with first fluting, and the second electric current bridge is provided with second fluting; First fluting can adopt consistent groove width with second fluting, also the zone that a groove width diminishes can be set respectively.
The end opening that the described first electric current bridge and the second electric current bridge are connected with the wire clamp gripping member, this place's open design can make that the conveniently moving of holder on the electric current bridge is without hindrance.First electric current bridge fluting shape is local for radian designs, and produces the feel of break-make when cooperating holder to move.
The face that first clamping part is relative with second clamping part respectively is provided with at least one projection, and the width of the width of this projection and first fluting and second fluting adapts.
The first electric current bridge and the second electric current bridge are respectively equipped with the bridge joint hole, for when test, produce between test bridge joint and the electric current bridge and are electrically connected.
The wire clamp gripping member generally comprises pinching screw and wire frame, also can be spring clamp body.
3, beneficial effect
The electric connector of the technical program has solved the Insulation Problems of test adapter under the high pressure, can realize failure-free operation under the 1000V, can improve the proof voltage value of whole system, and integral product satisfies proof voltage requirement (IEC57A/1000V, UL 50A/600V).Current bar adopts two-piece design, and is provided with fluting, cooperates with holder, has overcome like product break-make insentience in the prior art, the problem of operability difference. and can add the explanation of sign property simultaneously, clearly show on off operating mode, the handled easily person uses; The metalwork volume is little, and materials are economized during production, and cost is low.
