Background technology
The part that isolating switch mainly is used for needing in the high voltage distribution installation to have a power failure is isolated reliably with live part, to guarantee the safety of service work.Traditional isolating switch galvanic circle comprises the pair of conductive arm, is installed in the contact or the fingertip of conductive arm one end, and the conductive arm other end is electrically connected terminal block by soft connection, is with rain cover in the soft connection.It cooperates with fingertip by contact realizes divide-shut brake.The shortcoming of this kind structure is: conductive arm is circular or square conduction foundry goods, and rain cover is semi-enclosed foundry goods, and the structure programming rate is fast, and radiating effect is poor, and foundry goods is prone to mass defect, unstable product quality.
The utility model content
The technical problems to be solved in the utility model provides the isolating switch conducting loop structure of a kind of good heat dissipation effect, steady quality and low cost of manufacture.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of isolating switch conducting loop structure, comprise the pair of conductive arm, an end of conductive arm is connected with contact or fingertip, and this contact and fingertip can cooperatively interact and realize the disconnection and the conducting of two conductive arms; Its innovative point is: described conductive arm is made of the inside grooved section bar of pair of openings; The other end of conductive arm is fixedly connected with junction block, and this junction block is a hollow aluminium section bar structure, and the junction block center is equipped with rotating conducting rod, and this conducting rod is electrically connected with conductive arm by soft connection.
Further, the both ends open place of described hollow aluminium section bar junction block is provided with shutter.
Further, described conducting rod is electrically connected with two grooved section bars of conductive arm respectively by two two wiring that ease back.
Advantage of the present utility model is: leading arm is made by open a pair of grooved section bar, and junction block is a hollow aluminium section bar structure, makes product under equal flow area, and area of dissipation increases greatly, has reduced the product temperature rise; Parts adopt the section bar processing cost low substantially, do not have casting defect, the quality stability height.
Shutter is established at the junction block two ends, avoids rainwater to enter when improving radiating effect and sparrow is cooked nest.And conducting rod is connected with conductive arm by two wiring that ease back, and increases the electric interface of conducting rod and conductive arm, reduces contact resistance, reduces temperature rise, makes that circulation is more reasonable.
