Description
Technical field
The present invention relates to High-performance radio frequency coaxial connector, particularly relate to a kind of self sealss high-performance coaxial connector.
Background technology
As a kind of important electrical connection components and parts, by the impact that Communication in China industry increases fast, there is unprecedented growth momentum in radio frequency (RF) coaxial connector in recent years.From overall development trend, the development along with the communication technology, technology of Internet of things and machine system develops rapidly by coaxial connector, becomes the indispensable key equipment in mobile communication transmission field.In order to adapt to the development of 4G communication, information superhighway and Internet of Things, communication device calls will reach high transfer rate, high s/n ratio, and this just needs various components and parts in system all to reach very high electricity function index.TD-LTE a new generation communication system is had higher requirement to the performance index of coaxial connector again, at present, three large operators have increased a performance assessment criteria-third order intermodulation newly to coaxial connector, General Requirements≤-150 ~-155dBc, and the installation stability of this index and coaxial connector is closely related.The coaxial connector being applied in base station system needs to consider water-proofing treatment; present stage, construction brigade protected mainly through clay and adhesive tape water-proofing treatment, heat-shrinkable T bush heat shrink mode and feeder line waterproof sealing box; but all these operations all need to complete at the scene; work trouble, and have work high above the ground risk.
Summary of the invention
Object of the present invention will provide self sealss high-performance coaxial connector exactly, the problem such as it can solve work on the spot trouble existing for existing mode of operation, work high above the ground has a big risk.
The object of the present invention is achieved like this: self sealss high-performance coaxial connector, comprise inner wire, insulator, outer conductor, it is characterized in that: described inner wire is fixed in outer conductor by insulator, described outer conductor is threaded with rear thread sleeve, be provided with cable in described rear thread sleeve and fix gland, described cable is fixed in gland and is placed with cable conductor cover; Cable is fixed between gland and rear thread sleeve and is provided with cable sealing ring.
O RunddichtringO is provided with between rear thread sleeve of the present invention and outer conductor, between outer conductor punching press and between connector mating surface.
Cable conductor cover of the present invention, cable fix gland and rear thread sleeve, are combined as a set of linkage, being threaded by rear thread sleeve, simultaneously by cable conductor cover, gland fixed by cable and rear thread sleeve is fixed.
In rear thread sleeve of the present invention, the mode of groove milling is provided with cable and fixes gland.
Gland fixed by cable conductor cover of the present invention, cable and rear thread sleeve is combined into a set of linkage, and a simple operations can realize three effects, and one has been the electrical connection of cable and coaxial connector; Two is attached cables, strengthens the stability that cable is connected with connector; Three has been sealing functions of connector, prevents rainwater dust from invading.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, conductor; 2, insulated support; 3, outer conductor; 4, cable conductor cover; 5, gland fixed by cable; 6, rear thread sleeve; 7, O RunddichtringO; 8, cable sealing ring.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described
With reference to accompanying drawing, self sealss high-performance coaxial connector, comprise inner wire 1, insulator 2, outer conductor 3, it is characterized in that: described inner wire 1 is fixed in outer conductor 3 by insulator 2, described outer conductor 3 is threaded with rear thread sleeve 6, be provided with cable in described rear thread sleeve 6 and fix gland 5, described cable is fixed in gland 5 and is placed with cable conductor cover 4; Cable is fixed between gland 5 and rear thread sleeve 6 and is provided with cable sealing ring 8.Between described rear thread sleeve 6 and outer conductor 3, between outer conductor punching press and between connector mating surface, be provided with O RunddichtringO 7.Described cable conductor cover 4, cable fix gland 5 and rear thread sleeve 6, are combined as a set of linkage, being threaded by rear thread sleeve, cable conductor are overlapped 4 simultaneously, gland 5 fixed by cable and rear thread sleeve 6 is fixed.In described rear thread sleeve 6, the mode of groove milling is provided with cable and fixes gland 5.During concrete enforcement, according to the requirement of coaxial connector installation dimension, the process before coaxial cable is installed, insert cable conductor cover by cable from rear thread sleeve, it is axially movable in rear thread sleeve that gland fixed by cable conductor cover and cable, do not get loose mutually; Rear thread sleeve is threaded with outer conductor, is tightened by spanner, simplifies operation, saves the time.In spanner rundown process, cable conductor cover clamping cable advances along connector shaft alignment hand of spiral, and cable outer conductor compression is fitted on the contact-making surface of outer conductor.By cable conductor cover, gland fixed by cable and rear thread sleeve is combined into a set of linkage, pass through linkage, cable is fixed gland and is advanced along connector shaft alignment screw thread rightabout, compress cable sealing ring, attached cable hermetically sealed connector, strengthen stationarity and the stability of cable, guarantee the stability of connector high electrical property, be provided with the sealing property of cable simultaneously, prevent the immersion of rainwater; Coaxial connector outer conductor and rear thread sleeve junction are provided with O RunddichtringO, play waterproof sealing effect to connector, and the cooperation port of punching press place of connector and connector is also provided with O RunddichtringO, effectively strengthen the overall sealing performance of connector; Cable conductor cover is used for the outer conductor of attached cable, plays a major role to the tension of cable and resistance to shock; Cable sealing ring is used for the oversheath of attached cable, the resistance to shock of cable is played a secondary role, by this 2 fixing, enhances the stability that coaxial connector is connected with cable, ensure that coaxial connector high performance index, ensure third order intermodulation≤-160dBc; Cable fixes that the flexible size of gland is relevant with the quantity of groove width, lobe and the degree of depth of groove, and it is provided with the elasticity of gland by the mode of groove milling, avoids the size affecting part in follow-up stamping procedure.
