Embodiment
Consult Fig. 1, Fig. 2, the utility model comprises housing 1, Adjusting bolt Adjusting screw 3, sleeve 5 and switching pin 8 compositions, described housing 1 is made up of dielectric 6 and inner wire 7, housing 1 is provided with nut 2 and back-up ring 11 for hollow step axle shape, its external diameter, one end of inner wire 7 is provided with axis hole, inner wire 7 coaxial being arranged in the housing 1, dielectric 6 is located between inner wire 7 and housing 1 endoporus, Adjusting bolt Adjusting screw 3 is provided with and is provided with draw-in groove 13 in stepped hole, the hole, and sleeve 5 is for cylindrical tube shape, its cylindrical shell are provided with external screw thread, the termination is provided with step; Adjusting bolt Adjusting screw 3 is set in housing 1 outside and draw-in groove 13 and back-up ring 11 clampings, sleeve 5 penetrates in the housing 1 and through external screw thread and is threaded with Adjusting bolt Adjusting screw 3, and switching pin 8 is that the axis hole of needle-like, one end insertion inner wire 7 is interior, the other end is connected with cable 10 through dielectric pad 9; Described Adjusting bolt Adjusting screw 3 radially be provided with several lock-screws 4.
The utility model is to use like this:
Consult Fig. 1, Fig. 2, inner wire 7 is inserted in the dielectric 6, in housing 1 endoporus of again dielectric 6 being packed into, adopt anchor clamps fixedly inner wire 7, the position of dielectric 6 in housing 1, pour into epoxy glue, baking oven dries by the fire 1-2h, obtains the housing 1 of connector.The heart yearn of strip off cable 10, on heart yearn, be inserted in dielectric pad 9 and the switching pin 8 and the pin 8 of will transferring, the heart yearn welding of dielectric pad 9 and cable 10, the pin 8 of will transferring after the welding penetrates in the sleeve 5 together with cable 10, sleeve 5 is threaded with Adjusting bolt Adjusting screw 3 through external screw thread, and it is right to make switching pin 8 penetrate inner wire 7 interior formation conductors slide contacts, rotation Adjusting bolt Adjusting screw 3, under the effect of back-up ring 11,3 of Adjusting bolt Adjusting screws rotate with respect to housing 1, simultaneously, Adjusting bolt Adjusting screw 3 is by screw drive sleeve 5, switching pin 8 axially moves together with cable 10, sleeve 5 is moved in housing 1, cause inner wire 7, the conductors slide contact that switching pin 8 forms with the precision of control phase coupling, is determined the final lengths of connector to flexible.Through regulate, after test finishes, the lock-screw 4 on the fastening adjustment swivel nut 3, and with epoxy glue with Adjusting bolt Adjusting screw 3, housing 1 and sleeve 5 solid envelopes, become flexible preventing.
For guaranteeing impedance basically identical on the transmission face, the high impedance compensation measure is adopted in internal diameter sudden change place between housing 1 and inner wire 7.
The utlity model has following advantage: the utility model connector front end interface is the BMA interface of standard, and the system of being convenient to connects; During adjusting, according to the computing formula of electrical length, the gap on its length compensates by the adjusting of connector, finishes so that the assembling of cable and connector is disposable; Because the length change amount that Adjusting bolt Adjusting screw revolves the connector that turns around is 0.35mm, the swivel nut phase place that whenever turns around only changes 7.6 ° when 18GHz, can greatly improve the precision of phase matched; For reducing reflection loss, the step place that produces in each conductor diameter variation has all adopted the compensation of high impedance section, and characteristic impedance accuracy is controlled in 50 ± 0.5 ohm; The utility model has been simplified the phase matched technology of cable and connector and has been improved its phase matched precision, reduce production costs, and it is small and exquisite to have a volume, easy to adjust, adjustable range is big, the degree of regulation height, insertion loss is low, and voltage standing wave ratio is little, stable high.
