Line plug.
The utility model is achieved through the following technical solutions: a kind of breaker secondary terminals row p-wire plug,
The plug includes copper chromium-plated tube, solid magnetic iron, copper chromium plating intubation, insulated conductor and external insulation layer；The solid magnetic iron is embedding
Enter in the copper chromium-plated tube, copper chromium-plated tube tail portion and copper chromium plating intubation are welded；The external insulation layer is coated on described
The periphery of copper chromium plating intubation；There are two the plug settings, and described insulated conductor one end is welded on the copper chromium plating intubation
On, the other end extends to outside the external insulation layer and connects with another plug.
Copper chromium-plated tube is used cooperatively with solid magnetic iron, when can make plug grafting with breaker central console secondary terminals socket hole
Internal thread ailhead realizes that absorption is fixed, and does not need artificially firmly to pin, and keeps its natural duration contact good, so that test is smooth
It carries out, improves test efficiency；Same root insulated conductor both ends are both provided with plug, can will be more when falling short of online
A plug is plugged into, and is realized extension lead, is met the distance used.
The head interface of the copper chromium-plated tube and the head interface of the solid magnetic iron are plane, the copper chromium plating
The head interface and breaker central console secondary terminals socket hole internal thread of the head interface of pipe and the solid magnetic iron are followed closely
Head mutually touches.Copper chromium-plated tube and the head interface of solid magnetic iron are all planes, be conducive to screw cap Multi-contact so that
The adsorption capacity of plug is stronger, and can guarantee that the electric conductivity of plug is good, and can guarantee that the logical magnetic property stabilization of plug can
It leans on.
The copper chromium-plated tube is cylindrical pipe fitting, and the solid magnetic iron is the magnet of cylindrical structure.
The outer diameter of the solid magnetic iron is 0.01mm smaller than the internal diameter of the copper chromium-plated tube；The solid magnetic iron and the copper plate
Chromium pipe is welded at the gap for being located at the plug both ends with soldering.Copper chromium-plated tube and the diameter of solid magnetic iron are arranged, so that real
Heart magnet can just be embedded in copper chromium-plated tube.
The external insulation layer is run through at the rear portion of the copper chromium plating intubation, and multiple plugs are simultaneously in use, be located at rear side plug
The copper chromium-plated tube insertion be located at front side plug the copper chromium plating intubation in.Multiple plugs use simultaneously, positioned at rear side
The insertion of copper chromium-plated tube is located in the copper chromium plating intubation of front side, thus realize the p-wire more effect that connects, it can be achieved that sub-signal function
Energy.
It is compared with the prior art, utility model has the advantages that this plug uses the form of magnetic plug, is inhaled with magnetism
Attached to replace artificially pinning, allowing p-wire plug to arrange with breaker secondary terminals, jack contact is good and duration contacts well, makes
Breaker mechanic property test is fast and efficiently completed；This plug is at low cost, convenient to use, and power grid can be effectively reduced
Maintenance cost saves activity duration and manpower, improves economic benefit.
