Abstract
A copper and steel integral-type fixed contact consists of a contact body and a steel bracket and is characterized in that the contact body and the steel bracket are fine-cast together; one part of the steel bracket, positioned in the contact body, is provided with a punching hole; after being stretched, the punching hole forms an inserting claw; and by the punching hole and the inserting claw, the contact body and the steel bracket are firmly combined together. Formed by fine-casting the contact body and the steel bracket, the fixed contact is firm on structure and simple on processing procedures, can realize the recycling of leftover materials of scrap red copper on the premise of no changing the electrical properties, save non-ferrous metal, and reduce the production cost by 20% compared with that of the split-type fixed contact.
Description
Technical field
The utility model belongs to the appliance switch annex, particularly a kind of copper bearing steel all-in-one static contact.
Background technology
Fixed contact is mainly used in specifically being installed on the transducer on the interior earthed switch of high-tension switch cabinet.Existing fixed contact rear portion is that support, front portion are contact body, and front and rear is one and adopts copper material to make.The problem of its existence is: whole be copper material, add need mill man-hour, operations such as plane, press-bending, the production cycle is long, waste of raw materials is many, causes fixed contact production efficiency low, the manufacturing cost height.Proposed a kind of " separated static contact " in CN201048090, it is to be configured to propping up by contact body, and its special character is: described contact body is that split is connected with support, and support is a steel material.Because contact body is the red copper profile shapes, manufacturing procedure is many, and waste of material is big.This separated static contact concrete structure is divided into two kinds again, and a kind of is that support is overlapped on the contact body, connects by bolt when dispatching from the factory, need after taking apart when the user uses busbar is connected with bolt again with contact body, support three, complex operation, switching performance is bad, causes electric conductivity to reduce.Another kind of structure be contact body with support between dock the back welding, machining period is long, need the postorder processing, weld is easy to generate slag inclusion, dry joint, structure is insecure.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of sound construction, can utilize useless red copper to process, and manufacturing procedure is simple, the copper bearing steel all-in-one static contact that reduces production costs greatly under the prerequisite that does not change electric property.
The copper bearing steel all-in-one static contact that the utility model relates to, constitute by contact body and steel bracket, its special character is: the smart casting of described contact body and steel bracket together, and being positioned at the contact body position at steel bracket is provided with and blurts out, the blurting out back that stretches forms and inserts pawl, by blurt out and slotting pawl with contact body and firm the combining of steel bracket.
This fixed contact is to be formed by contact body and the smart casting of steel bracket, sound construction, and manufacturing procedure is simple, under the prerequisite that does not change electric property, can realize the regeneration of old and useless red copper tailing, save non-ferrous metal, reduce production costs, compare cost with separated static contact and reduce about 20%.

Embodiment
As shown in the figure, this fixed contact is formed by red copper contact body 1 and steel bracket 2 smart castings, be positioned at contact body 1 position at steel bracket 2 and be provided with and blurt out 4,4 backs that stretch of blurting out form and insert pawl 3, by blurt out 4 and slotting pawl 3 with contact body 1 and steel bracket 2 firm combining.
