Abstract
The utility model relates to a gas tightness radio frequency coaxial connector, including casing and insulator, the inner conductor of setting in the casing between insulator and the casing be provided with the sealing washer on the insulator in the groove of insulator, the sealing washer external diameter is unanimous with the casing internal diameter, be provided with the barb on the inner conductor, its axial position with the coincidence of sealing washer position. The utility model discloses simple structure, the gas tightness is good, and the yield is high.
Description
Technical field
The utility model relates to radio frequency connector technical field, specifically discloses a kind of air-tightness radio frequency (RF) coaxial connector.
Background technology
Radio frequency (RF) coaxial connector usually between inner wire and insulator, increase sealing ring (silicon rubber) between insulator and housing and enclose water-tight function by compression seal.In assembling process, after sealing ring loading insulator, external diameter is greater than shell inner hole (sealing ring can play water-tight effect after compression), makes troubles to assembling, sealing ring cracky, reduces air-tight water-proof function.
Utility model content
Goal of the invention of the present utility model is: provide for overcoming the above problems the air-tightness radio frequency (RF) coaxial connector that a kind of structure is simple, air-tightness good, rate of finished products is high.
The technical scheme that the utility model adopts is such:
A kind of air-tightness radio frequency (RF) coaxial connector, comprise housing and be arranged on insulator, the inner wire in housing, between described insulator and housing, on described insulator, be provided with sealing ring in groove of insulator, described sealing ring external diameter is consistent with housing inner diameter; Described inner wire is provided with hangnail, and its axial location overlaps with described sealing ring position.
Further, the formation direction, inclined-plane of described hangnail is identical with described inner wire direction of insertion.
In sum, owing to adopting technique scheme, the beneficial effects of the utility model are:
The great advantage of this structure is adopted to be after insulator (putting sealing ring) is pressed into housing, sealing ring can not be out squeezed, after being pressed into inner wire again, by hangnail extruding insulation on inner wire, insulator expands, form radial pressure crush seal circle, sealing ring and inner walls are fitted tightly, reaches air-tightness requirement.This kind of structure substantially increases the qualification rate in production process, reduces production cost, improves production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is inner conductor structure schematic diagram described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and 2, a kind of air-tightness radio frequency (RF) coaxial connector, the insulator 2, the inner wire 3 that comprise housing 1 and be arranged in housing 1, between described insulator 2 and housing 1, described insulator 2 is provided with sealing ring 4 in groove of insulator, described sealing ring 4 external diameter is consistent with housing 1 internal diameter; Described inner wire 3 is provided with hangnail 5, and its axial location overlaps with described sealing ring 4 position, forms radial compression power, meets air-tightness requirement.
The formation direction, inclined-plane of described hangnail 5 is identical with described inner wire direction of insertion, makes inner wire 3 not by the obstruction of hangnail 5, can be pressed into smoothly.
During assembling, first sealing ring 4 is inserted in insulator 2, sealing ring 4 external diameter flushes with insulator 2, insulator 2 is pressed into housing 1, because sealing ring 4 external diameter flushes with insulator 2, in the process of press-in housing 1, sealing ring 4 can not be out squeezed, sealing ring 4 is in nature relaxed state, now there is no radial compression power between sealing ring 4 and housing 1, be pressed into inner wire 3 again, after inner wire 3 puts in place, hangnail 5 position and sealing ring 4 position, insulator 2 outer ring are in same radial position, hangnail 5 extruding insulation 2, insulator 2 expands crush seal circle 4, radial compression power is formed between sealing ring 4 and housing 1, sealing ring 4 and housing 1 inwall fit tightly, reach air-tightness requirement.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
Claims (2)
1. an air-tightness radio frequency (RF) coaxial connector, comprise housing and be arranged on insulator, the inner wire in housing, between described insulator and housing, on described insulator, be provided with sealing ring in groove of insulator, it is characterized in that: described sealing ring external diameter is consistent with housing inner diameter; Described inner wire is provided with hangnail, and its axial location overlaps with described sealing ring position.
2. a kind of air-tightness radio frequency (RF) coaxial connector according to claim 1, is characterized in that: the formation direction, inclined-plane of described hangnail is identical with described inner wire direction of insertion.
