Technical field
The utility model relates to a kind of connector that is used for delivered current or signal, relates in particular to the hermetically sealed connector that a kind of inside has hermetically-sealed construction.
Background technology
Being in great demand to hermetically sealed connector on the market, the hermetically-sealed construction of existing hermetically sealed connector adopts glass sealing or encapsulating structure mostly, glass sealing is to place glass dust in the housing endoporus of connector and the gap between the contact, heating makes glass dust be solidified into an integral body and forms sintered glass, utilize sintered glass to bear pressure and realize sealing, the reliability height of this sealing means, structure is little, need not increase that parts and structure can realize sealing and contact fixing in housing.But glass-sealed processing cost is higher, and the design of sealing structure is limited by many process for sealing; Sealant pouring and sealing simple in structure, technology is also uncomplicated, but sealing property is bad, and particularly in the environment that range of temperature is bigger, the encapsulating structure is subjected to Temperature Influence can separate with contact with housing gradually, makes hermetically-sealed construction lose efficacy.
The utility model content
The purpose of this utility model is to provide that a kind of technology is simple, cost is low, good sealing effect, can be applied in the hermetically sealed connector in the bigger environment of range of temperature.
For achieving the above object, the utility model adopts following technical scheme: a kind of hermetically sealed connector, comprise housing, be set with contact by the insulating element that is set in the contact front portion in the through hole in the housing, the insulating element leading section cooperates with the housing roof pressure, be equipped with the overflow contact that front end cooperates with the insulating element roof pressure and the elastic sealing gasket in the gap between the housing on the contact, the rear sleeve of contact is provided with the compacting ring that compresses elastic sealing gasket forward, and compacting ring is installed in the housing.
Has the insulator that the front end that is set in the contact rear portion cooperates with the elastic sealing gasket roof pressure between the mating surface of described clamp ring and contact, have the roof pressure step surface towards the rear end that cooperates with the clamp ring roof pressure on the outer peripheral face of insulator, clamp ring compresses elastic sealing gasket forward by insulator.
Described clamp ring by and housing in through hole between tight fit be installed in the housing, the outer peripheral face that the through hole in clamp ring and the housing cooperates is provided with annular knurl.
Described insulator stretches out the rear end face of clamp ring, and the rear end of clamp ring has the retaining edge that extends internally, and insulator cooperates with the clamp ring roof pressure by roof pressure step surface and roof pressure between the retaining edge and cooperates.
The sealing gasket of described elastic sealing gasket for constituting by rubber.
Be equipped with elastic sealing gasket on the contact of the present utility model, the front end of elastic sealing gasket cooperates with the insulating element roof pressure, the front portion of insulating element cooperates with the housing roof pressure, the rear end of the elastic sealing gasket compacting ring roof pressure interior with being installed in housing cooperates, elastic sealing gasket is in the gap between overflow contact and the housing under the extruding of insulator and compacting ring, realize sealing, because elastic sealing gasket has better elastic, axial compression can be bigger its radial dimension of increase, the change in size of the elastic sealing gasket that variations in temperature causes can be changed by the radial dimension that elastic sealing gasket produces owing to axial compression prevents, therefore, even if variations in temperature than overall situation in the sealing function of elastic sealing gasket can be not destroyed yet.
Through hole tight fit in clamp ring of the present utility model and the housing, the outer peripheral face that clamp ring cooperates with through hole in the housing is provided with annular knurl, annular knurl can tightly be bitten the hole wall of the through hole in the housing, prevents that clamp ring from moving relative to housing, realizes clamp ring fixing in housing.
