Fig. 3 is the schematic diagram that public connector of the present invention and female connectors are in connection status.In conjunction with Fig. 1, Fig. 2 and Fig. 5, when public connector 7 is connected with female connectors 6, the stay 9 of public connector 7 at first contacts with the joint datum level 614 of female connectors 6, rises to peak flat-top 617 along oblique angle 615a, the face of cylinder 615, lead-in chamfered 616 then.Be that stay 9 reaches maximum torsional deformation by lax free state.Public connector 7 continues to move towards female connectors 6, when public connector datum level and female connectors datum level when colliding, stay 9 enters inclined-plane 618 through the intersection of flat-tops 617 and support inclined 618, the energy that stay 9 is twisted will discharge rapidly.Form the internal tooth of stay 9 and a tangential force between the support inclined 618, all internal tooth of stay 9 withstands on the support inclined 618 of female connectors firmly, or the intersection of support inclined 618 and flat 619.Contact gap between the datum level 713 of the datum level 614 of female connectors and public connector just in time is zero at this moment, and stay 9 is α with the angle of support inclined, as shown in Figure 4.Wherein, 90 °≤α≤115 °.And the energy that this moment, stay 9 was twisted does not discharge fully, the direction of the power that torsion discharges is pointed to the tangential direction of support inclined 618, the almost vertical again slope of stay 9, so a very little tangential force will produce a very big thrust in this normal direction, the 920 pairs of support inclined in top 618 that are stay produce than the big tens times of thrusts to hundred times of tangential torsion, the direction of power is pointed to support inclined, stay 9 has 12～24 teeth in whole circumference, these teeth are distributed in whole circumference, direction is another to be caused, making a concerted effort that they produced is very large, and this has made a concerted effort to produce the axial contact pressure that engage datum level 713 and 614 of public connector with female connectors.So, fast inserting of the present invention, the joint datum level of self-locking type radio frequency (RF) coaxial connector had both reached the zero clearance, kept very big contact pressure again, the face of cylinder 615 of female connectors 6 is just in time dropped in the hole 716 of public connector 7 simultaneously, this is inserted soon, the axiality of self-locking type radio frequency (RF) coaxial connector has also reached perfect condition, so fast inserting of the present invention, the self-locking type radio frequency (RF) coaxial connector has good shield effectiveness when being locked, reduced the radio-frequency leakage phenomenon, make the connector characteristic impedance be in good matching status, the electromagnetism wave energy is transmitted very unblockedly, reduced reflection loss, improve efficiency of transmission, reduced intermodulation distortion simultaneously widely.
Again the action principle and the mechanism of stay is further described below.With before female connectors is connected, all internal tooths of stay are in relaxed state at public connector.When public connector is connected with female connectors, be subjected to the joint datum level 614 of female connectors 6, oblique angle 615a, the interior tooth ends 920 of the face of cylinder 615 and lead-in chamfered 616 restrictions, climb up peak flat-top 617 gradually by lax free state, the gradient torsional deformation that is risen in gap between the stay internal tooth, but the internal tooth position still can keep original linear state, when slipping over flat-top 617 and entering support inclined 618, the datum level 614 of female connectors 6 begins to collide with the datum level 713 of public connector 7, this moment, the internal tooth 92 of stay slided to fast inserting along support inclined 618 rapidly, the axle center of self-locking type radio frequency (RF) coaxial connector, and stay is when arriving support inclined 618 or support inclined 618 with flat 619 intersections, the angle of stay and support inclined 618 is almost the right angle, intersection in support inclined 618 and flat 619, the strain energy of distortion that stay is twisted does not all discharge, there has not been the space between the internal tooth of stay and the support inclined 618, the tangential direction that the internal tooth of restriction stay continues to prolong support inclined 618 moves on, but the torsion of tangential direction also in action, make stay fill in surface firmly in support inclined 618, at this moment support inclined is withstood at the top 920 of internal tooth, from stay force analysis at this moment as can be known, because tangentially also there is torsion in stay, stay almost becomes 90 ° with the angle on inclined-plane, at this moment very little tangential torsion, just can produce a huge thrust in its normal direction, this thrust produces simultaneously in the end of each internal tooth, direction is pointed to the axle center, 12 horizontal components to this thrust of 24 teeth produce with joint efforts the datum level 713 of 614 pairs of public connectors of datum level of female connectors, and it is of the present invention fast slotting that Here it is, the self-locking type radio frequency (RF) coaxial connector engages the theoretical foundation that datum level produces immense pressure after adopting this structure.Just this power solved insert soon, the joint datum level gap of self-locking type radio frequency (RF) coaxial connector is the problem of zero-sum datum level pressure.These axial 12 are exactly the coupling mechanism force that design needs to 24 teeth with joint efforts, and keeping of this coupling mechanism force is the enabling capabilities that leans on each internal tooth.The shape of external tooth and internal tooth as shown in Figure 6.
Two sections less section A B and two sections distortions that are used for internal tooth 92 of CD, when internal tooth 92 bears coupling mechanism force, because AB and CD be connected as a single entity through internal tooth 92, so AB and CD are in alignment, the support base that is to say internal tooth 92 is AD, obviously just can support very big power.This design of stay can guarantee to have that enough rigid support are inserted soon, the confining force of the due coupling mechanism force of self-locking type radio frequency (RF) coaxial connector when being connected when locking state.In addition, the hold-down ring that is pressed on the stay can bear the thrust of stay to it effectively, has reduced the stress deformation of stay, has improved the ability to bear of stay.
Fast insert when needs unclamp, during the self-locking type radio frequency (RF) coaxial connector, as long as push away stay 9 with the folding position 731 of the swivel nut 73 of public connector.Push the power that stay will overcome open and always have two, first is the residue torsion of stay, and second is stay end 920 and the static friction power of support inclined 618.These two power all are very little, can push back flat-top 617 to the internal tooth of stay easily with the folding position 731 of swivel nut 73 and can unclamp radio frequency (RF) coaxial connector, have realized the fast insert-pull of radio frequency (RF) coaxial connector thus.
Of the present inventionly fast insert, the self-locking type radio frequency (RF) coaxial connector can be than higher reliability is arranged with thread connecting mode, loosening phenomenon often appears in the radio frequency (RF) coaxial connector that is threaded when mechanical oscillation, loosening under vibrational state for solving screw thread coupling, in some special important events, as the phase-locked system transmission, put on a very thin stainless steel wire to brill one aperture on the angle of special six-sided nut and prevent nut loosening.Adopt fast inserting of the present invention, the self-locking type radio frequency (RF) coaxial connector, because when public connector 7 engages with female connectors 6, stay rests on the intersection of support inclined 618 or support inclined 618 and flat 619, this moment, the angle of stay and support inclined 618 was almost 90 °, stay and support inclined 618 be tight, support inclined 618 is withstood at its top 920 firmly, the torsion of the stay that is twisted is not all discharged, when radio frequency (RF) coaxial connector is subjected to vibratory impulse because of extraneous power, remaining torsion all the time in action, the direction of torsion is pointed to the axle center, shakes tighter and tighter, and it will further improve its coupling mechanism force.In addition, stay scope of activities of the present invention is less, so be not easy to produce fatigue, therefore the connect-disconnect life of radio frequency (RF) coaxial connector of the present invention is very long, can be considerably beyond 100 settings of some existing products.
As long as dish shaped lock sheet with multiple teeth of the present invention can rest on the support inclined 618 optional position and can both play the locking effect, therefore the projected length of support inclined on axis is the largest cumulative error in the time of can regarding part processing and assembling as, the about 0.40mm of this projected length, even get the composite error that 0.20mm distributes to part processing and assembling by relatively more conservative design, can guarantee that also the part qualification rate has required, so adopt of the present inventionly fast insert, the self-locking type radio frequency (RF) coaxial connector has good processing technology, can reduce manufacturing cost.
Adopt of the present inventionly fast insert, the self-locking type radio frequency (RF) coaxial connector can guarantee outer conductor guiding earlier when connecting, the just available then pin of inner wire inserts, and enough contact lengths and contact pressure are arranged between the inner wire, has improved the contact reliability of inner wire.
Adopt fast slotting, self-locking type radio frequency (RF) coaxial connector of the present invention, public connector and the joint datum level zero clearance of female connectors when being connected really can have been solved, joint datum level at them keeps enough big contact pressure simultaneously, make radio frequency (RF) coaxial connector characteristic impedance continous-stable, have less reflection coefficient, lower insertion loss and radio-frequency leakage and good intermodulation performance; In mechanical properties, fast to insert, self-locking type radio frequency (RF) coaxial connector insertion force is little, coupling mechanism force is big, and releasing force is little, and auto-lock function is reliable and stable, and anti-vibrating and impact power is strong, adverse environment resistant; In addition, the stay that of the present inventionly fast insert, the self-locking type radio frequency (RF) coaxial connector adopts, its scope of activities is little, so of the present inventionly fast insert, the self-locking type radio frequency (RF) coaxial connector is littler than existing radio frequency (RF) coaxial connector volume, weight is lighter, can be arranged on the electronic equipment with higher density, and amount of copper consuming descends, manufacturing procedure reduces, and also can save resource in a large number simultaneously.
Of the present inventionly fast insert, the self-locking type radio frequency (RF) coaxial connector can be used on the general civilian or industrial equipment, also can be used for the Aeronautics and Astronautics field.
