Summary of the invention
For the deficiency that prior art exists, the utility model provides the money base cladding electrical contact that a kind of connectivity is good, firm, electric conductivity is stable.
For achieving the above object, the utility model provides following technical scheme: a kind of money base cladding electrical contact, include the conduction briquetting of silver-based layer and copper alloy layer pressing and forming, it is characterized in that: described conduction briquetting offers the installing hole running through two symmetric outer surface, and two of symmetry outer surfaces are positioned at installing hole place and are respectively equipped with removable pair of conductive contact, conductive contact includes leading electric contact and additional conductive contact, described leading electric contact includes main contacts body and is connected with main contacts body and can be inserted into the connecting screw rod in installing hole, described additional conductive contact includes auxiliary contact body and is connected with auxiliary contact body and can be inserted into the conductive casings in installing hole, conductive casings offers the screwed hole for connecting screw rod locking.
Adopt technique scheme, installing hole is put by offering on conduction briquetting, and on conduction briquetting, two symmetrical outer surfaces arrange removable conductive contact respectively, after arranging like this, the electric conductivity of conduction briquetting is stablized, conduct electricity by the alternative face of point, and conductive contact is by dominating electric contact and forming with the additional conductive contact that leading electric contact is spun by screw thread, not only be convenient to install, and can produce conducting electricity the coupling mechanism force of briquetting after leading electric contact is combined with additional conductive contact, make the connection between the silver-based layer in conduction briquetting and copper alloy layer more compact and firm, can not come off easily and have influence on electric conductivity.
The utility model is set to further: the joining place of connecting screw rod and leading electric contact is provided with conducting boss, the outer peripheral face of conducting boss offers ring-type short slot, the elastic conduction circle that the inwall being provided with outer peripheral face and installing hole in ring-type short slot is conflicted.
Adopt technique scheme, on connecting screw rod, the setting of conducting boss is the conductivity in order to increase connecting screw rod, make the electric conductivity of conductive contact better, in conducting boss upper annular short slot, the setting of elastic conduction circle then further ensure that connecting screw rod can be communicated with fully with between conduction briquetting, improves conductivity.
The utility model is further set to: the outer peripheral face of conductive casings is evenly equipped with the conductive bumps of conflicting with installing hole inwall.
Adopt technique scheme, on conductive casings outer peripheral face, the setting of conductive bumps makes the conductive contact between conductive casings and installing hole inwall by putting alternative face, improves electric conductivity, makes its electric conductivity more stable simultaneously.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
