Summary of the invention
The utility model purpose is to provide a kind of compact conformation, and manufacturing cost is lower, the knife-shaped isolator of lighter weight, problem such as it is higher to have solved the manufacturing cost that existing knife-shaped isolator exists, and weight is heavier.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises insulator foot, be located at the input and the output of base both sides respectively, input is hinged with moving contact and is electrically connected, output is provided with the fixed contact that matches with moving contact and is electrically connected with output, moving contact is connected with rotating shaft, rotating shaft and action bars one end are hinged, the through hole that the action bars other end passes on the base extends to outside the base, and correspondence is provided with the groove that is provided with shaft parallel with the rotating shaft below on the described base.Action bars pulling rotating shaft drives moving contact and cooperates connection with fixed contact, rotating shaft can be embedded in the groove on the base during cooperation, eliminated the obstruction that the base countershaft moves downward, thereby increased the stroke of moving contact, and the height of fixed contact can shorten relatively, reduced the consumptive material of making fixed contact, reduced the manufacturing cost of knife-shaped isolator, the shortening of offering groove and fixed contact height simultaneously on base has also alleviated the overall weight of knife-shaped isolator to a certain extent.
As preferably, described moving contact is made of two plate bodys, and described two plate bodys are provided with several jump rings near the end, and described jump ring passes two plate bodys.Two plate bodys are made by conductive metallic material, can improve the reliability that moving contact is electrically connected with fixed contact under the effect of jump ring, and jump ring passes and can guarantee cooperating of jump ring and moving contact plate body, prevent to come off, simultaneously also saved manufacturing cost, saved operation, performance is more stable.
As preferably, described fixed contact both sides are respectively equipped with vertical backplate, and the distance between the two vertical backplates is slightly larger than the diameter of described jump ring.When moving contact cooperated with fixed contact, jump ring was positioned between two vertical backplates, and two vertical backplates can prevent that jump ring from flicking, and guaranteed cooperating of moving contact and fixed contact, guaranteed the reliability that circuit connects.
As preferably, a side of described fixed contact is installed with the convex body of horizontally set, and described moving contact is provided with convex body one side corresponding to fixed contact and is provided with the limit body that the end protrudes from moving contact downwards.When moving contact cooperated with fixed contact, the limit body on the moving contact withstood on the convex body of fixed contact, prevented that excessively pressing down of moving contact from damaging, and improved useful life of the present utility model.
As preferably, described base is provided with several installing holes, forms deep gouge around the described installing hole.Knife-shaped isolator can be installed on the mounting panel of distribution box by installing hole fitted bolt nut, and is easy for installation.
As preferably, described moving contact is connected by the insulation connector with action bars, and described connector constitutes by the connecting portion that is connected with moving contact with the adapter sleeve of rotating shaft socket.The insulation connector is set between moving contact and rotating shaft, can prevents the generation of electric leakage accident, improved the fail safe that the utility model uses.
As preferably, the cross section of described groove is a semicircular structure, and comprises deep that the adapter sleeve with described connector matches and the superficial part that matches with rotating shaft.Groove adopts semicircular structure can make rotating shaft and groove fit tightr, prevents the loosening of rotating shaft, the stability that the assurance moving contact cooperates with fixed contact.
Therefore, the utlity model has compact conformation, manufacturing cost is lower, and lighter weight is safe in utilization, cooperates characteristics such as reliable, easy for installation.
