Background technology
Usually, electric connector all comprises housing, and the endoporus of housing is provided with contact through insulator; Contact is used for transmission current or signal, and housing is used to protect contact, and insulator is used to realize the insulation between contact and the housing; In multi-core connector, insulator also has the effect that keeps the insulation between each contact, insulator generally by following several kinds; The soft insulator of rubber-like, through the plastic insulation of Shooting Technique moulding, the sintered glass cake that the mode through the sintered glass powder forms; The good sealing effect of glass cake, the compressive resistance performance is good, but when connector is used under water.The glass cake can absorb moisture, and glass has the advantages that insulation resistance descends after the moisture absorption, and this just will cause the insulation resistance of glass sealing product to descend, and cause the insulation resistance of connector defective.
The utility model content
The purpose of the utility model is to provide a kind of compressive sealed connector under water; To solve in the prior art when connector uses the sintered glass cake to make insulator, reduce the underproof problem of insulation resistance of the connector that causes because of resistance after the sintered glass cake moisture absorption.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of compressive sealed under water connector; Comprise housing, be fixed with more than one contact through the sintered glass cake in the endoporus of housing, said sintered glass cake sealing paste on the end face of the inserted terminal of contact and the grafting of adaptive contact is provided with sealing gasket; The endoporus hole wall of the periphery of sealing gasket and housing is sealed and matched, and the sealing of each contact is located in the perforating that is provided with on the sealing gasket and by passing in the perforating.
Said housing is provided with the Stop structure with the sealing gasket compression fit.
Described perforating is the outer little shoulder hole of imperial palace of diameter; Each contact through and the hole wall of the reduced diameter section of each self-corresponding perforating between the sealing that is sealed and matched be located on the sealing gasket; Be respectively arranged with the rigid insulation cover in the enlarged diameter section of each perforating; The inner face of rigid insulation cover is pressed on the step surface of perforating, said Stop structure through and the outer face of rigid insulation cover between compression fit and sealing gasket compression fit.
Described Stop structure is for being fastened on the collar on each self-corresponding contact respectively, and each collar cooperates with each self-corresponding rigid insulation cover roof pressure, and each collar is arranged on the housing through the assembling that on each self-corresponding contact, is arranged in the annular groove.
Said contact is that two ends all are double end contact pins of inserted terminal.
Described sealing gasket is a rubber gasket.
Described rigid insulation cover is plastic insulation covering.
Sealing paste is provided with sealing gasket on the end face of the sintered glass cake of the utility model; The endoporus hole wall of the periphery of sealing gasket and housing is sealed and matched, and each contact sealing is located on the sealing gasket, realizes sintered glass cake and extraneous sealing; After product has assembled; Tide vapour and water can't touch the sintered glass cake, and the underproof problem of insulation resistance of the connector of having avoided causing because of the sintered glass cake moisture absorption makes the insulation property of connector be protected.
The Stop structure that the sealing gasket of the utility model is set on the housing is pressed on the end face of sintered glass cake; Guaranteed being sealed and matched between the endoporus hole wall of periphery and housing of sealing gasket more reliably, and being sealed and matched between each contact and the sealing gasket.
The enlarged diameter section of the perforating of the utility model is provided with the rigid insulation cover; Sealing gasket is adjacent to the end face of sintered glass cake and the endoporus hole wall of housing; Adopt the rigid insulation cover through with the step surface of perforating between cooperate inside crush seal pad, guarantee the endoporus hole wall of sealing gasket and housing and drain with the air of the contact position of the end face of sintered glass cake, suppress the rigid insulation cover with collar then; Guarantee that moisture can't get in the connector, reliably prevent the sintered glass cake moisture absorption.

Embodiment
A kind of embodiment of compressive sealed connector under water; In Fig. 1 ~ 4, this under water the housing 2 of compressive sealed connector have the endoporus before and after running through, be fixed with more than one contact 1 through sintered glass cake 6 in the endoporus of housing 2; The contact 1 here is the double end contact pin; The two ends of contact 1 are inserted terminal, the rubber gasket 5 that all has been sticked on two end faces of sintered glass cake, and the endoporus hole wall of the outer peripheral face of rubber gasket 5 and housing 2 is sealed and matched; Be provided with perforating in the placement of contact 1 on the rubber gasket 5, contact 1 passes from each self-corresponding perforating.Perforating is the outer little shoulder hole of imperial palace of diameter; The hole wall part of the reduced diameter section of perforating is sealed and matched with contact 1; Be provided with plastic insulation covering 4 in the enlarged diameter section of perforating, the inner face roof pressure of plastic insulation covering 4 is on the step surface of perforating, and the outer peripheral face of contact 1 is provided with annular groove; Be provided with collar 3 in this annular groove, the outer face compression fit of collar 3 and corresponding plastic insulation covering 4.Plastic insulation covering 4 makes both be sealed and matched on the end face of sintered glass cake 6 rubber gasket 5 jam-packeds.
Contact in the foregoing description is the double end contact pin; Two ends are inserted terminal, are provided with rubber gasket at the two ends of contact, when an end of contact is inserted terminal; The other end of contact can be encapsulated in the housing, also just need rubber gasket be set.
