Description

A kind of electric connector of high temperature high voltage resistant
Technical field
The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector of high temperature high voltage resistant.
Background technology
Generally speaking, electric connector all is that work is at normal temperatures or in the environment a little more than normal temperature, at this moment less demanding to the heatproof of electric connector, the insulator of electric connector can be to hold the not high resin material of warm ability, but just needs electric connector to have the higher warm bearing capacity that holds in the environment of some HTHP.The electric connector operated by rotary motion is on the panel of equipment, the one end combines with panel, at this moment pressure and temperature can pass to electric connector and the insulating material that destroys electric connector from panel and make its heat absorption deliquescing even fusing, and insulator will deviate to cause electric connector to lose efficacy from the metallic shell of electric connector body with contact under the effect of pressure then.In order to reach the higher warm bearing capacity that holds, the insulating material of electric connector is generally selected the high-temperature insulation vitreum for use, the contact of electric connector is arranged in the metallic shell of electric connector body by glass insulator, and between the rear end of contact side face and metallic shell of electric connector body, grommet is set, grommet is sleeved on the contact, and grommet is between the non-inserted terminal of glass insulator and contact.Glass insulator generally is made by the sintered glass powder, glass insulator and metal shell and and contact between be and be sealed and matched, generally realize by frictional force its location in metal shell, reducing or step also can be set on the inner peripheral surface of housing sometimes realize the front end location of glass insulator in metal shell, general grommet or the interface sealing body of all adopting in the rear end location of glass insulator in housing realized.At work, heat from the device panel place is a part of through losing behind the grommet, and the heat that arrives glass insulator like this can decrease, and the more important thing is, the time that grommet can make heat arrive insulator is delayed, and increases the time that electric connector is at high temperature worked.However, when temperature reaches 2000 degree or when higher, still can't guarantee that glass insulator does not melt in the operating time in several seconds, even if glass insulator is fusing not, it has been deliquescing, frictional force between glass insulator and the metallic shell of electric connector body can diminish even disappear so, reducing on the metal shell inner peripheral surface or step also can't be born the power that glass insulator is subjected to, and under high pressure glass insulator also can be deviate from from the metallic shell of electric connector body and causes electric connector to lose efficacy together with contact.
Summary of the invention
The purpose of this utility model with the electric connector that a kind of high temperature high voltage resistant is provided, to solve the problem of under HTHP, from the metallic shell of electric connector body, deviating to cause the electric connector inefficacy in existing under pressure together with contact owing to the glass insulator deliquescing.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, comprise metal shell, sealing is provided with glass insulator in the metal shell, sealing is equipped with contact in the glass insulator, described metal shell inner peripheral surface is provided with the baffle plate that cooperates towards the front end face of connector inserted terminal with glass insulator, and the relevant position of baffle plate is provided with the hole of passing through for contact.
Described baffle plate is wholely set on the inner peripheral surface of metal shell.
Be provided with dielectric between the hole wall in the hole that the confession contact of described baffle plate passes through and the contact.
Described contact is provided with grommet near the back segment of its non-inserted terminal, and the front end face of grommet and the rear end face of glass insulator are adaptive.
Described grommet is the double-deck grommet that is successively set on the contact.
Described metal shell inner peripheral surface and glass insulator cooperation place are provided with annular groove, and the relevant position of glass insulator has the convex tendon that cooperates with described annular groove.
Metal shell inner peripheral surface of the present utility model is provided with the baffle plate that cooperates towards the front end face of connector inserted terminal with glass insulator, the relevant position of baffle plate is provided with the hole of passing through for contact, pressure from the glass insulator rear end is delivered on the baffle plate by glass insulator, and pass to the metallic shell of electric connector body by baffle plate, even if after the frictional force between glass insulator deliquescing, itself and the metal shell diminishes, the suffered pressure of glass insulator also can be born by baffle plate, and glass insulator still can not deviate from from metal shell.
Grommet of the present utility model is the double-deck grommet that is successively set on the contact, when heat passes to glass insulator from non-inserted terminal of the present utility model, time-lag action through double-deck grommet can guarantee that glass insulator does not melt, and reaches job requirement in 5 seconds.
Metal shell inner peripheral surface of the present utility model and glass insulator cooperation place are provided with annular groove, the relevant position of glass insulator has the convex tendon that cooperates with described annular groove, the convex tendon of glass insulator cooperates the adhesion that can increase between glass insulator and the metal shell with the annular groove of metal shell, thereby increases bearing capacity of the present utility model.
