Utility model content
The technical problem to be solved by the present invention is to provide a kind of high temperature and pressure high current connectors, can bear
The starting the arc pulse of 8000V, the steady-state current for conducting 40A, and can work under 300 DEG C of high temperature the long period.
The technical solution of the utility model are as follows:
A kind of high temperature and pressure high current connector includes the ceramic mounting plate of tubulose, is set in ceramic mounting plate
It the jack contact of screw-contact structure, the shell being set in outside ceramic mounting plate and swivel nut and is connected on shell
Nut, the front end of the shell extend into swivel nut, and being screwed together on the rear end of shell has nut, and the shell is
Al-alloy casing, the outer surface of Al-alloy casing are coated with black anodizing thermal control coating.
Annular lug is provided with to form step surface structure on the inner wall of the ceramics installation front edge of board, and described inserts
The front end of hole contact and step face contact, which are supported, closes.
The jack contact includes supporting sleeve and the screw-contact that is fixed in supporting sleeve, described
The outer wall of screw-contact is fixedly connected with the inner wall of supporting sleeve front, and screw-contact is integrated with supporting sleeve
Change shaping structure.
The nut includes with internal thread front and positioned at the rear portion of ceramic mounting plate rear end, the nut
Front connect with the external thread spiro fastening in housing rear end portion, the rear portion of nut resists the rear end of ceramic mounting plate and shell, and institute
The vibrationproof moving-coil of annular is provided between the rear portion for the nut stated and ceramic mounting plate and the rear end of shell.
The vibrationproof moving-coil is high-temperature alloy elastic ring.
The advantages of the utility model:
The jack contact of the utility model is spring finger structure, can greatly increase the contact area with conductor, thus full
The needs of sufficient high current conduction；The mounting plate of the utility model is using ceramic mounting plate, suitable for using under high temperature environment, and
Good insulating；The shell of the utility model is Al-alloy casing, has good electromagnetic shielding performance, outer surface is coated with black
Anodic oxidation thermal control coating, thermal emissivity rate ε > 0.85, further increases the thermoradiation efficiency of the utility model, to improve
Heat-sinking capability, enables the utility model long period to work under 300 DEG C of high temperature；The utility model is provided with vibration proof
Circle, vibrationproof moving-coil resist the rear end of ceramic mounting plate and shell, can guarantee well anti-between ceramic mounting plate and shell
Vibration, acceleration and impact property.
