Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
In prior art, the spring structure that flexible clamp piece that in connector, outer conductor is connected used with feeder line outer conductor uses, easily produces and comes off with spring when this structure easily causes feeder line attaching, and assembling complexity.For head it off, this programme provides a kind of radio frequency (RF) coaxial connector, and Fig. 1 is the decomposition texture schematic diagram of the radio frequency (RF) coaxial connector that provides of the utility model embodiment; Fig. 2 is the installation diagram of the radio frequency (RF) coaxial connector that provides of the utility model embodiment.As depicted in figs. 1 and 2, radio frequency (RF) coaxial connector comprises an outer conductor 9, described outer conductor 9 centers offer a cavity, in the cavity of described outer conductor 9, be provided with an inner wire 7 that can be connected with feeder line inner wire, one end that described outer conductor 9 is provided with inner wire 7 is also connected with a rear thread sleeve 2, described rear thread sleeve 2 front ends are placed in described outer conductor 9 cavitys, which is provided with the flexible clamp piece 4 for fixing feeder line outer conductor.
Preferably, described rear thread sleeve 2 front ends offer screw thread, can screw and be placed in described outer conductor 9 cavitys, and seal by a seal 3, in described rear thread sleeve 2 inner chambers, are provided with sealing ring 1, and seal by sealing ring 1 and feeder line 10.
Because described flexible clamp piece 4 can replace the spring fastener in prior art structure.So this radio frequency (RF) coaxial connector assembling is simple, syndeton is stable, reliable, feeder line outer conductor and outer conductor difficult drop-off.
In the present embodiment, as preferred version, described rear thread sleeve 2 front ends offer an annular opening groove, and described flexible clamp piece 4 is placed in described open slot.
In the present embodiment, as further preferred version, described flexible clamp piece 4 is rounded groove lasso.This rounded groove lasso can replace the spring fastener in prior art structure, be designed to snap in described rear thread sleeve 2, and can be from rear thread sleeve 2 free dropping.
In the present embodiment, as preferred version further, described rounded groove lasso is provided with protrusion draw-in groove.Described protrusion draw-in groove make with feeder line 10 assemble easier.
When feeder line packs in rear thread sleeve, described protrusion draw-in groove just snaps in the trough of feeder line outer conductor, thereby make to be connected between feeder line and connector more reliable, clamping performance is good, and there is good electric property, its return loss has reached 30.0dB by original 22.1dB, has improved the competitiveness of product on market.
In prior art, inner wire adopts mode of grooving, in the time being connected with feeder line inner wire, feeder line inner wire is because feeder line 10 burrs do not go to the greatest extent, or bending, external force struts inner wire to break, so that feeder line 10 wire strippings require is very high, and be difficult for clamping, reduce the reliability that product uses, so class connector quality is on the low side.
For head it off, in the present embodiment, as preferred version, on the inwall of described outer conductor 9, offer a groove, in described groove, be provided with nylon bush 6.
