Abstract
The utility model relates to an airtight coaxial connector used outdoors, comprising a housing, an insulating supporting body located inside an inner hole of a housing and a central conductor located inside the insulating supporting body, characterized in that the central conductor and the outer wall of the insulating supporting body are respectively provided with a plurality of spaced seal grooves provided with seal rings therein along a circumferential direction, and the surface of the housing, except a connection portion, is coated with a corrosion resistant molding powder layer. The central conductor and the outer wall of the insulating supporting body are respectively provided with a plurality of seal rings and seal grooves, and simultaneously the surface of the non-connection portion of the housing is added with the molding powder layer, thereby increasing the tightness of the axial connector, and also increasing the corrosion resistance of the coaxial connector; and the airtight coaxial connector used outdoors has a better outdoor environment resistant performance, and can be reliably used even under a bad environment.
Description
Technical field
The utility model relates to a kind of coaxial connector, is specifically related to a kind of for outdoor coaxial connector.
Background technology
At present, along with the fast development of the communications industry, coaxial connector is also constantly updating, and a lot of coaxial connector is all developing to miniaturization.When these coaxial connectors are applied in when outdoor, owing to month after month be exposed in the air throughout the year, standing to expose to the sun and rain, so the inevitable requirement coaxial connector has better air-tightness, otherwise gas, water can enter into the inside of connector, and then affect the transmission of signal.In order to achieve the above object, people design the radio frequency (RF) coaxial connector of air tight structure already, number be CN201797099U " a kind of radio frequency (RF) coaxial connector of air tight structure " such as the Chinese patent Granted publication, this coaxial connector comprises outer conductor, the dielectric of coaxial setting and is in the interior center conductor of dielectric centre bore, the outer wall of dielectric offers seal groove along leading in week, be provided with sealing ring in the seal groove and cooperate with the inner wall sealing of outer conductor, be provided with circumferential, axial limit structure between the centre bore of center conductor and dielectric.
Adopt above-mentioned radio frequency (RF) coaxial connector, easy to assembly, air-tightness is good.Can realize the air-tightness requirement under the environmental limit temperature.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of for the outdoor and better coaxial connector of air-tightness.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of for outdoor airtight coaxial connector, comprise shell, be arranged in the insulation support body and the center conductor that is positioned at insulation support body of shell endoporus, it is characterized in that: the outer wall of described center conductor and insulation support body is along a plurality of seal grooves that upwards are interval with respectively built-in sealing ring week, and the surface spraying of described shell except connecting portion has the corrosion resistant molding powder layer of one deck.
Preferably, described center conductor and insulation support body outer wall upwards respectively are provided with two described seal grooves along week.
In above-mentioned each scheme, the flange outer face of described shell is provided with the annular boss around described insulation support body, and this annular boss can improve three rank performances of coaxial connector.
Be preferably, the flange outer face of described shell is provided with the cannelure that the cross section that is positioned at the described annular boss outside is swallow-tail form, is embedded with sealing ring in this cannelure.This cannelure can prevent that sealing ring from dropping out, and can further improve the airtight level of coaxial connector.
In such scheme, the surface of described center conductor is provided with along the straight burr of its axial distribution and hangnail, the effect of straight burr is the anti-torsional moment that increases coaxial connector, and the effect of hangnail is the axial force that increases coaxial connector, and plays to a certain extent airtight effect.
Compared with prior art, because center conductor of the present utility model, insulation support body outer wall are respectively arranged with a plurality of sealing rings and seal groove, while has additional the molding powder layer on the surface at the disconnected position of shell, thereby both improved the air-tightness of coaxial connector, improved again simultaneously the corrosion resistance of coaxial connector, thereby the utlity model has the performance of better anti-outdoor environment, even if under rugged environment, also can reliably use.

Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1 to 6, this coaxial connector comprises shell 1, is arranged in the insulation support body 2 of shell 1 endoporus and is positioned at the afterbody of insulation support body 2 with the center conductor 3 of jack, wherein, shell 1 one ends have flange 11, has the external screw thread 12 that connects usefulness on the other end outer peripheral face, the outer face of this external screw thread and flange becomes connecting portion, in the present embodiment, the surface spraying of shell except connecting portion has the corrosion resistant molding powder layer 13 of one deck, with environmental adaptability and the resistance to corrosion of strengthening this coaxial connector.Simultaneously be provided with annular boss 14 around insulation support body 2 at above-mentioned flange 11 end faces, this annular boss 14 can improve three rank performances of coaxial connector.Be positioned on the end face of flange in annular boss 14 outsides and have the cannelure 15 that the cross section is swallow-tail form, be embedded with sealing ring 4 in this cannelure 15, this cannelure 15 is limited in sealing ring in the groove reliably.
The outer wall of above-mentioned insulation support body 2 arranges a sealing ring 4 along upwards being interval with two seal grooves 21 week in each seal groove, the sealing circle can adopt resistant to elevated temperatures sealing ring.
Above-mentioned center conductor 3 is the N-type structure, and the outer wall of this center conductor 3 upwards also is interval with two seal grooves 31 along week, each seal groove 31 interior sealing ring 4 that arrange, and the sealing circle also can adopt resistant to elevated temperatures sealing ring.Be provided with straight burr 32 and the hangnail 33 of its axial distribution on center conductor 3 surfaces, they are positioned at sealing ring 4 and away from a side of the flange 11 of shell.Center conductor at insulation support body 2 end faces has a step 34 simultaneously, and this step 34 plays the effect of two-way fool proof with above-mentioned insulation support body 2 spacing sides at close shell end face of flange.
In order further to improve air-tightness, the contact-making surface between shell 1 and the insulation support body 2 is provided with an auxiliary hangnail 16, with further increase axial force and air-tightness.
