Technical field
The utility model relates to a kind of conducting element, particularly a kind of silver metal alloyed oxide electrical contact.
Background technology
Electrical contact is the vitals of primary cut-out, switch cubicle, isolating switch, earthed switch, and its performance directly affects quality and the useful life of these High-Voltage Electrical Appliances.Silver metal alloyed oxide electrical contact is primarily of silver alloy bisque and copper alloy bisque composition, silver alloy bisque and copper alloy bisque are by pressing and forming, and pressing is after block, and its surface is conducting surface, but, in bonding processes, pressing mold is after use after a while, and its precision there will be deviation, the conducting surface of electrical contact then can not be smooth, affect electric conductivity, and the cost of pressing mold is higher, frequent replacing then can improve production cost.
Constantly research and develop through these those skilled in the art, by arranging conductive contact on the conducting surface of electrical contact, the problem of conductivity instability is solved with this, usual conductive contact welds with adopting between electrical contact, because the quantity of conductive contact is more, and small volume, this process can only adopt and manually carry out at present, not only consuming time, and the precision of welding cannot be guaranteed, and covert improves production cost.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of low production cost, good conductivity, structure simple silver metal alloyed oxide electrical contact.
For achieving the above object, the utility model provides following technical scheme: a kind of silver metal alloyed oxide electrical contact, include ag alloy layer and the copper alloy layer with ag alloy layer pressing and forming, ag alloy layer and copper alloy layer are pressed into rectangular block shape body, the outer surface of rectangular block shape body is provided with conductive contact, it is characterized in that: the installation place outer surface of described rectangular block shape body being positioned at conductive contact offers inserting groove, the bottom of inserting groove is provided with the location notch with its conducting, conductive contact includes the contact bodies be revealed in outside inserting groove, contact bodies is provided with the grafting block with inserting groove adaptation, the bottom of grafting block is provided with the locating piece with location notch adaptation, the outer peripheral face of described grafting block offers ring-type short slot, also be provided with elastic conduction circle in ring-type short slot, the outer peripheral face of elastic conduction circle is provided with some conductive bumps.
Adopt technique scheme, conductive contact and rectangular block shape body are in removably connecting, in installation process, only need the grafting block of conductive contact be pressed in inserting groove, the location notch on the locating piece on grafting block and rectangular block shape body is made to implement to locate and just complete installation, not only good conductivity, and it is easy for installation, in grafting block upper annular short slot, the setting of elastic conduction circle can be worked as grafting block and entered into after in inserting groove and the inwall of inserting groove keeps conflicting, grafting block is further located, can effectively prevent conductive contact from coming off by rectangular block shape body, and the outer peripheral face of elastic conduction circle is provided with conductive bumps, the setting of this conductive bumps then can further improve its electric conductivity, make the electric conductivity of electrical contact more stable.
The utility model is set to further: location notch is triangular shape, and locating piece is the triangular shape locating piece with location notch adaptation, the outer surface of locating piece offers at least one short slot axially arranged along it.
Adopt technique scheme, arrange structure so simple, and the contact-making surface of locating piece and location notch is large, bonding strength is high.
The utility model is further set to: be provided with at least two pieces of connecting plates in rectangular block shape body.
Adopt technique scheme, the setting of connecting plate can strengthen the bonding strength of ag alloy layer and copper alloy layer in rectangular block shape body.
Below in conjunction with accompanying drawing, the utility model is further described.
