Abstract
The invention relates to a quick plug radio frequency coaxial connector. When the connector available on the market currently is plugged, a corresponding body clearance is generated between a convex front end face of an outer conductor of a female plug and the concave front end face of an outer conductor of a male plug, so electric performance of the connector declines; meanwhile, the contact is susceptible to causing connection failure, and disassembly and assembly are difficult. The invention discloses a quick plug connector, which comprises a male plug and a female plug which are in insertion connection, wherein the male plug comprises a first outer conductor, a first inner conductor, a contact and a front sleeve; a convex barb surrounds the front end of the contact; a spacer sleeve is arranged between the first outer conductor and the contact, and a spring plate is arranged at the inner front end of the first outer conductor; and a spring positioned at the rear end of the contact is arranged between the front sleeve and the first outer conductor. The connection structure provided by the invention guarantees effective separation, ensures that the connector has high electric performance and that the female plug can be inserted and connected with a threaded female plug, and therefore has two purposes.
Description
Technical field
The present invention relates to a kind of radio frequency (RF) coaxial connector, be specifically related to a kind of Quick-plugging radio-frequency coaxial connector.
Background technology
Radio frequency (RF) coaxial connector is not widely used in signal transmission network, plays transmission line electrical connection, centrifugation.Current connector is mostly screw-type and connects, in use in order to make female outer conductor projection recessed portion close contact corresponding with public plug outer conductor, need to tighten public plug nut, simultaneously but in the time of dismounting, need to extract public plug with the nut that wrench is backed out public plug, dismantle very inconvenient.And along with the fast development of the communication technology, increasing work will be carried out in the wild, threaded connection connector not only volume should not carry greatly, and need to assist spanner nutting while installing, wastes time and energy, and can not meet the requirement of field work.
When existing connector plugs together in the market, public plug central inner conductor first contacts with female, contact head inserts in female outer conductor afterwards, in the time that female outer conductor protrusion front end face overlaps with the outer conductor front end recessed face of public plug, contact head front end barb falls into female outer conductor interior forward end groove, and hook groove front end face, now plug together release, when separation, public plug solution lock tube front end inclined-plane coordinates in contact head outer ramp, contact head front end barb place is drawn in, in the time that contact head front end barb peak diameter is less than the diameter of female outer conductor interior forward end groove, contact head departs from female outer conductor interior forward end groove, now public plug separates with female, this kind of structure in use exists following problem to be: after plugging together, the structure of connector can not guarantee that female outer conductor protrudes front end face and public plug outer conductor front end recessed face, contact head front end barb rear end face overlaps with female outer conductor interior forward end groove front end face, between the inevitable protrusion front end face at female outer conductor and public plug outer conductor front end recessed face, produce corresponding body space, cause connector electrical property to decline, the outer conductor interior forward end groove that while contact head may produce female causes Joint failure, and it is not its insertion force and withdrawal force are excessive, easy to assemble.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Quick-plugging radio-frequency coaxial connector, the electric property decline, the unreliable and not easy-to-dismount problem of mechanism that in use exist effectively to overcome existing connector.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of quick plug connector, comprise the public plug and the female that plug together connection, public plug comprises the first outer conductor, the first inner wire, contact head and protheca, the front end ring of contact head is wound with protruding barb, it is characterized in that: between the first outer conductor and contact head, be arranged with interstage sleeve, the first outer conductor interior forward end is provided with reed; Between protheca and the first outer conductor, be provided with the spring that is positioned at contact head rear end.
Above-mentioned female is that screw-type connects, female comprises the second inner wire and the second outer conductor, the second inner wire front end is provided with and the first inner wire shrinkage pool coordinating of pegging graft, and is provided with the groove coordinating with protruding barb on the second outer conductor, and groove rear end is provided with sealing ring.
Above-mentioned the first outer conductor interior forward end is provided with draw-in groove, and reed snaps in draw-in groove.
Between above-mentioned contact head and protheca, be arranged with pressure ring one, the rear end of protheca is nested with between pressure ring two, the first outer conductors and pressure ring and is arranged with pressure ring three.
Above-mentioned interstage sleeve is sleeve-shaped, and its front end annular array has through hole, the ring array side of showing, rear end tooth.
Above-mentioned protheca outer setting has annular knurl, and front end is provided with locating surface.
Above-mentioned protruding barb is for opening lobe formula structure, and its inside is provided with protruding cambered surface.
Above-mentioned reed is bowl-type.
The front and back end of above-mentioned spring is respectively arranged with packing ring, and the packing ring of front end is arranged on pressure ring two and pressure ring three front ends, and the packing ring of rear end is arranged on contact head and pressure ring one front end.
The number of above-mentioned through hole is identical with square number of teeth order, and through hole and square tooth position are interlaced.
Compared with prior art, the present invention has advantage and effect are as follows:
1, in separation process, play effect spacing and that step down by the interstage sleeve that arranges plugging together, while plugging together, when the rectangular through holes of interstage sleeve front end moves to the annular cambered surface top of contact head interior forward end projection, contact head could shrink completely, interstage sleeve plays the effect of stepping down, and public plug and female are plugged together; After plugging together, interstage sleeve restPoses with the stretching, extension of spring, and the face of cylinder of its front end can effectively prevent that contact head from shrinking, and plays position-limiting action, thereby guarantees the reliability of bindiny mechanism; When separation, the effect of stepping down, with spring contraction slow astern set a distance, is played in the face of cylinder of interstage sleeve front end, reserves contact head and shrinks required space completely, guarantees that public plug effectively separates with female.
2, by contact spring being set at linkage interface place, make bindiny mechanism guaranteeing to connect reliably simultaneously, indirectly take into account the coincidence of mechanical electric datum level, make connector there is higher electrical property.
3, female has retained the linkage interface of conventional threads formula, can plug together and be connected with screw-type public plug simultaneously, at one stroke dual-purpose.
