Abstract
The utility model provides a soft attitude copper aluminium connector of high -low pressure electrical switching, including soft attitude aluminum alloy wire barrel and terminal block, the one end of soft attitude aluminum alloy wire barrel is equipped with the first transitional coupling portion that is the throat form, the terminal block includes coalesced copper layering post and second transitional coupling portion, second transitional coupling portion and first transitional coupling portion are connected, be equipped with the cylindric groove on the soft attitude aluminum alloy wire barrel, the utility model discloses an anti flow ability and the more traditional connector of electric conductive property obviously strengthen, simultaneously, still have easy processing, characteristics that matter is light.
Description
Technical field
The utility model relates to electrical cnnector field, is specifically related to a kind of high-low pressure electric switch soft state copper aluminium connector.
Background technology
In traditional electric power system, air switch terminals be that copper aluminium is connected between service conductor, because material is different, resistance is different, electric current by the heat of rear generation and the coefficient of expansion different, through after a period of time, originally contact tie point closely and can produce loosening heating, when attendant cannot process in time, heating can grow in intensity, finally cause air switch and service conductor junction to be blown and service conductor also can damage short circuit and be blown up by wire because crossing thermal insulation layer, cause power failure.Although this type of rate of breakdown is high, because little, the easy process of its power failure range, risk factor are not high and always out in the cold.
Have various switching connector on the market at present, this switching connector adopts copper aluminium material material to be welded, connected by switching connector and air switch terminals are connected with service conductor end, the face that becomes after adding connection device contacts with the fine copper in face, and contact-making surface is large much thus substantially increase guide performance.But the employing common aluminum alloy of existing switching connector and copper product are made, anti-flow ability, in use still there is potential safety hazard in poor electric conductivity.
Utility model content
The utility model provides a kind of high-low pressure electric switch soft state copper aluminium connector, solves the anti-flow ability of existing connector, the problem of poor electric conductivity.
The utility model realizes the technical scheme that above-mentioned technique effect adopts:
A kind of high-low pressure electric switch soft state copper aluminium connector, comprise soft state aluminium alloy wire barrel and terminal board, one end of described soft state aluminium alloy wire barrel is provided with the First Transition connecting portion in reducing shape, described terminal board comprises oxygen-free copper press strip post and the second transition connection portion, described second transition connection portion is connected with First Transition connecting portion, and described soft state aluminium alloy wire barrel is provided with tubular groove.
Further, described oxygen-free copper press strip post and the second transition connection portion are one-body molded.
Further, described soft state aluminium alloy wire barrel and First Transition connecting portion are one-body molded.
Further, the bottom of described tubular groove is provided with towards the arc-shaped concave of described terminal board side depression, and the end of described soft state aluminium alloy wire barrel is provided with chamfering.
Further, described second transition connection portion is connected with First Transition connecting portion and is welded to connect by high-speed friction.
The beneficial effects of the utility model are: the wire barrel of soft state aluminium alloy and the terminal board of oxygen-free copper material adopt high-speed friction welded shaping by the utility model, because of the anti-flow ability of the wire barrel of soft state aluminium alloy and electric conductivity strong, make the anti-flow ability of whole connector and electric conductivity comparatively convention connectors obviously strengthen, simultaneously, also have and be easy to processing, the feature of light weight.
