Description
Technical field
The utility model relate to a kind of radio frequency (RF) coaxial connector, belongs to connector art field.
Background technology
Radio frequency (RF) coaxial connector may be used for the connection of circuit board to circuit board, circuit board radio frequency module or radio-frequency module radio frequency module.Existing radio frequency (RF) coaxial connector as viewed in figures 5-8, generally include outer conductor, inner wire and the insulator for being connected both, but the structure of existing insulator 2 ' normally cross section is T-shaped, and the thickness G of this structure insulator 2 ' when outer conductor internal diameter D and inner conductor outer diameter d is certain is thinner, the area of section H being same as support is less, causes its support strength inadequate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of radio frequency (RF) coaxial connector, when outer conductor internal diameter and inner conductor outer diameter constant, realize, under the prerequisite ensureing impedance, strengthening the support strength of connector by the structure changing insulator.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of radio frequency (RF) coaxial connector, comprise outer conductor, inner wire, insulator is provided with between described outer conductor and inner wire, described insulator is circulus, be provided with the manhole that can insert for inner wire along its central axis, the lateral surface of described insulator is also provided with multiple groove along its contour.
Aforesaid a kind of radio frequency (RF) coaxial connector, is characterized in that: the end profile of described insulator has three projections along its contour spaced set.
Aforesaid a kind of radio frequency (RF) coaxial connector, is characterized in that: the quantity of described groove is three, be set in qually spaced in described insulator side, and each groove is all communicated with described manhole.
Aforesaid a kind of radio frequency (RF) coaxial connector, is characterized in that: the shape of described groove is the one in V-type, fan-shaped or other geometries.
Aforesaid a kind of radio frequency (RF) coaxial connector, is characterized in that: described groove is positioned at the centre position of the side of described insulator.
Aforesaid a kind of radio frequency (RF) coaxial connector, is characterized in that: the internal diameter of described outer conductor is 3.2mm, and the external diameter of described inner wire is 1.33mm.
The beneficial effects of the utility model are: by adopting circular insulator, and multiple groove is set in its side, under the prerequisite ensureing impedance, add the area of section of supporting surface, when outer conductor internal diameter and inner conductor outer diameter constant, strengthen the support strength of connector.

Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As Figure 1-4, a kind of radio frequency (RF) coaxial connector, comprise outer conductor 1, inner wire 3, insulator 2 is provided with between described outer conductor 1 and inner wire 3, described insulator 2 is circulus, the manhole 21 that can insert for inner wire 3 is provided with along its central axis, the lateral surface of described insulator 2 is also provided with multiple groove 22 along its contour, the quantity of the present embodiment further groove 22 is three, be set in qually spaced in described insulator 2 side, and each groove 22 is all communicated with described manhole 21, now, under the prerequisite ensureing impedance, the area of section K(of supporting surface is as Fig. 4) shown in relative to H(of the prior art as Fig. 8) shown in increase, resistance value in the present embodiment maintains 50 Ω.As calculated, the area of section K of insulator 2 supporting surface after improvement is about 1.7 times of the area of section H of existing insulator 2 ' supporting surface, when outer conductor internal diameter 3.2mm and inner conductor outer diameter 1.33mm is constant, strengthens the support strength of connector.
The end profile of described insulator 2 has three projections 23 along its contour spaced set, because insulator 2 is circular symmetrical structure, be convenient to position when assembling, and the intensity of assembling is better by arranging three projections 23 at its end.
The shape of described groove 22 is the one in V-type, fan-shaped or other geometries, and under the condition meeting impedance parameter, be convenient to the shape of the injection moulding demoulding, the structure adopted in the present embodiment is bowl shaped structure.
Described groove 22 is positioned at the centre position of the side of described insulator 2, due to the support force of balanced connector, ensures that structure is more firm.
In sum, a kind of radio frequency (RF) coaxial connector that the utility model provides, when outer conductor internal diameter and inner conductor outer diameter constant, realize, under the prerequisite ensureing impedance, strengthening the support strength of connector by the structure changing insulator.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
