Abstract
The utility model, which belongs to the communication technology field, particularly relates to a radio frequency coaxial connector comprising an outer conductor, an inner conductor and a medium. The medium is arranged between the outer conductor and the inner conductor; an inner-side protrusion for preventing axial movement of the medium is arranged at the inner wall of the outer conductor; and a grooving matched with the inner-side protrusion is arranged on the inner conductor. Besides, an outer-side protrusion for preventing the axial movement of the medium is arranged on the outer wall of the inner conductor; and a groove matched with the outer-side protrusion is arranged at the medium. Because of the arranged the grooving and groove, the electrical performance of the connector is effectively improved.
Description
Technical field
The utility model belongs to communication technical field, is specifically related to a kind of radio frequency (RF) coaxial connector.
Background technology
The axial restraint of radio frequency (RF) coaxial connector medium generally adopts at the outer conductor inwall and relates to into a barb form at present, fixed effect is better like this, improve the structure of product, reduced the cost of product, but meanwhile, the electric property of product has also reduced, requiring under the situation that is not very high, this structure is applied widely, when frequency of utilization reaches: 0～4GHz, and voltage standing wave ratio requires WSWR≤1.05 o'clock, and this variation will have to pay attention to.
Summary of the invention
The utility model provides a kind of radio frequency (RF) coaxial connector, can further improve its electric property.
Its concrete technical scheme is as follows:
Described radio frequency (RF) coaxial connector is characterized in that: this connector comprises outer conductor, inner wire and medium; Described medium is arranged between outer conductor and the inner wire; Be provided with at the outer conductor inwall and prevent the axially movable inner bulge of medium, be provided with the grooving suitable with this inner bulge in the conductor.
Described radio frequency (RF) coaxial connector further design is that inner bulge is inboard barb.
Described radio frequency (RF) coaxial connector is characterized in that: this connector comprises outer conductor, inner wire and medium; Described medium is arranged between outer conductor and the inner wire; Be provided with at the inner wire outer wall and prevent the axially movable outside of medium projection, be provided with the groove suitable with this outside raised position at medium.
Described radio frequency (RF) coaxial connector further design is that outside projection is outside barb.
The beneficial effects of the utility model are to be provided with at the outer conductor inwall to prevent the axially movable inner bulge of medium, be provided with the grooving suitable with this inner bulge in the conductor, perhaps be provided with at the inner wire outer wall and prevent the axially movable outside of medium projection, be provided with the groove suitable with this outside raised position at medium.Can make the electric property of product effectively improve so that impedance is constant like this.
Description of drawings
Fig. 1 is the utility model generalized section.
Among the figure: the 1-outer conductor; The 2-medium; The 3-inner wire; The 4-inner bulge; 5-outside projection; The 6-grooving; The 7-groove.
Embodiment
The utility model radio frequency (RF) coaxial connector comprises outer conductor 1, inner wire 3 and medium 2; Medium 2 is arranged between outer conductor 1 and the inner wire 3; Be provided with at outer conductor 1 inwall and prevent the axially movable inner bulge 4 of medium, be provided with the grooving 6 suitable with this inner bulge 4 at inner wire 3.Be provided with at inner wire 3 outer walls and prevent from the axially movable outside of medium projection 5 being provided with the groove 7 suitable with protruding 5 positions, this outside at medium 2.Inner bulge 4 is inboard barbs, and outside projection 5 is outside barbs.The medium 2 that is arranged between outer conductor 1 and the inner wire 3 is made by plastic rubber material PBTG20.
Utilize formula of impedance, Z=60/ √ ε lnD/d, wherein D represents the internal diameter of outer conductor 1, and d represents the external diameter of inner wire 3, is proportional relation between D and the d.
As figure, two kinds of situations are arranged, first kind of situation: when outer conductor 1 was provided with inner bulge 4, D diminished, and is constant in order to guarantee impedance, and d also should be along with diminishing, and so be provided with grooving 6 at inner wire 3, d diminishes, and makes that the ratio of D/d is constant, and impedance is constant.
Second kind of situation: to be provided with the outside protruding 5 the time when inner wire 3, and it is big that d becomes, constant in order to guarantee impedance, opened groove 7 at medium 2, is exactly the admixture medium of air and medium 2 like this, makes that equally impedance is constant.
The setting of this grooving 6 and groove 7 makes impedance constant, thereby makes the electric property of radio frequency (RF) coaxial connector get a promotion greatly.
Claims (4)
