Description

Hermetically sealed connector

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, and glass sealing is in the housing endoporus of connector and the gap between the contact, to place glass dust, and 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 of this sealing means is high, and 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 in the environment that particularly range of temperature is bigger, the encapsulating structure receives Influence of Temperature can separate with contact with housing gradually, makes hermetically-sealed construction lose efficacy.

The utility model content

The technology that the purpose of the utility model is to provide a kind of two ends of contact to be inserted terminal 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 realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of hermetically sealed connector; Comprise housing, be set with contact through being set in the anterior insulating element of contact in the through hole in the housing, the two ends of contact are the inserted terminal that can peg graft with adaptive contact; 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 clamp ring that compresses elastic sealing gasket forward, and clamp 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 through insulator.

Described clamp ring through 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 through roof pressure step surface and roof pressure between the retaining edge and cooperates.

The sealing gasket of said elastic sealing gasket for constituting by rubber.

Be equipped with elastic sealing gasket on the contact of the 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, and the rear end of the elastic sealing gasket clamp ring roof pressure interior with being installed in housing cooperates, and elastic sealing gasket is in the gap between overflow contact and the housing under the extruding of insulator and clamp ring; Realize sealing; Because elastic sealing gasket has better elastic, its radial dimension of increase that axial compression can be bigger, 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 not be destroyed yet.In addition, the two ends of the contact of the utility model are inserted terminal, all can peg graft with adaptive contact, and the utility model can be used for the switching of connector.

Through hole tight fit in clamp ring of the 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.
