Abstract
The utility model relates to an electric connector field especially involves a high low frequency of resistant wide temperature loads in mixture connector. Should load in mixture the connector includes casing, low frequency contact and high frequency contact, be equipped with the installation wall between the both ends in the casing, the installation is equipped with the contact mounting hole on the wall, low frequency contact and high frequency contact separately through corresponding glass insulator fixation in the contact mounting hole of correspondence. This connector reduced in other words every glass insulator volume, lifting surface area and with the cooperation area of casing, when using, partial pressure at first can be shared to the installation wall, the pressure that glass insulator received after the lifting surface area reduces is corresponding reducing also, in addition, glass insulator's bulk reduction also makes reducing that its expend with heat and contract with cold's reacting phase answered, has reduced its and the probability of casing separation. To sum up, this high low frequency of resistant wide temperature loads in mixture connector has solved current adoption glass insulator's the easy gas seal failure's of electric connector problem.
Description
Technical field
The utility model relates to electric connector field, particularly relates to a kind of high-low frequency mixed loading connector of resistance to wide temperature.
Background technology
Along with the continuous maturation of deep-sea electric connector, adopt the High-voltage-resistatransformer hermetic seal connector of glass insulator concerning no longer strange us.In above-mentioned electric connector, contact is all fixedly be assemblied in the housing of electric connector by glass insulator, thus reliably cuts off between the two ends of electric connector.
In the electric connector of existing employing glass insulator, glass insulator is all be made up of an all-in-one-piece glass cake, all contacts are all by its fixing assembling in the housing, what this just made glass insulator seems larger for the area bearing pressure, if the pressure between electric connector two ends is excessive, then can be easy to cause the impaired phenomenon in the junction between glass cake and housing, glass insulator entirety can be made to deviate from housing, cause the hermetic seal of electric connector to lose efficacy.
When especially using in the environment that some temperature ranges are larger, because the volume of glass insulator is comparatively large and larger with the contact area of housing, in the process of variations in temperature, glass insulator very likely can because of expanding with heat and contract with cold and the factor such as both sides pressure reduction and being torn, and this also can cause the hermetic seal of electric connector to lose efficacy certainly.Therefore, the serviceability temperature of the electric connector of current employing glass insulator is generally limited between-60 DEG C to 200 DEG C.
Summary of the invention
The purpose of this utility model is the high-low frequency mixed loading connector providing a kind of resistance to wide temperature, the problem lost efficacy with the easy hermetic seal of the electric connector solving existing employing glass insulator.
In order to solve the problem, the high-low frequency mixed loading connector of resistance to wide temperature of the present utility model is by the following technical solutions: the high-low frequency mixed loading connector of resistance to wide temperature, comprise housing, low frequency contact and high-frequency contact, assembly wall is provided with between two ends in described housing, described assembly wall is provided with contact cavity, and low frequency contact and high-frequency contact are fixedly assemblied in corresponding contact cavity each via corresponding glass insulator.
The inner wire of high-frequency contact is fixedly assemblied in outer conductor by corresponding glass insulator.
Described assembly wall and housing are integral type structure.
Owing to being provided with assembly wall between two ends in its housing of the high-low frequency mixed loading connector of this resistance to wide temperature, assembly wall is provided with contact cavity, and low frequency contact and high-frequency contact are fixedly assemblied in corresponding contact cavity each via corresponding glass insulator, therefore, be equivalent to the volume reducing each glass insulator, lifting surface area and with housing coordinate area, when in use, first assembly wall can share partial pressure, the pressure suffered by glass insulator after lifting surface area reduces also reduces accordingly, in addition, the volume of glass insulator reduces also to make its reaction of expanding with heat and contract with cold reduce accordingly, reduce the probability that it is separated with housing.In sum, the problem that the easy hermetic seal of electric connector that the high-low frequency mixed loading connector of this resistance to wide temperature solves existing employing glass insulator was lost efficacy.
Accompanying drawing explanation
Fig. 1 is the front view (band is analysed and observe) of the embodiment of the high-low frequency mixed loading connector of resistance to wide temperature;
Fig. 2 is the left view of the embodiment of the high-low frequency mixed loading connector of resistance to wide temperature.
Embodiment
The embodiment of the high-low frequency mixed loading connector of resistance to wide temperature, as shown in Figure 1-2, the high-low frequency mixed loading connector of this resistance to wide temperature comprises housing 11, low frequency contact 12 and high-frequency contact, the outer conductor 14 that high-frequency contact comprises inner wire 13 and is assemblied in inner wire 13.
In the present embodiment, this connector is cylindrical connector, and housing 11 is circular shell, is provided with assembly wall 15 between the two ends in housing 11, be integral type structure between assembly wall 15 and housing 11, can ensure that the positive confinement at assembly wall 15 and housing 11 cooperation position place is with firm thus.Assembly wall 15 is also provided with contact cavity, and contact cavity is the through hole running through assembly wall 15.
The outer conductor 14 of low frequency contact 12 and high-frequency contact is all fixedly assemblied in corresponding contact cavity each via the glass insulator of correspondence, the glass insulator between high and low frequency contact and assembly wall is called outer insulator 16 herein.
The inner wire 13 of high-frequency contact is also fixedly be assemblied in outer conductor 14 by corresponding glass insulator, sealing between the two ends that can realize outer conductor 14 thus cuts off, and the glass insulator between the inner and outer conductor of high-frequency contact is called interior insulator 17 herein.
Through test, adopt the high-low frequency mixed loading connector of this resistance to wide temperature of said structure can meet the temperature shock of-253 DEG C ~+327 DEG C, and ensure sealing property under this temperature shock.
In other embodiment of the high-low frequency mixed loading connector of resistance to wide temperature, also assembly wall and housing can be set to split-type structural, assembly wall is coordinated with housing fixing seal by forms such as Screw assembly, flange assemblings.
