Abstract
The invention relates to an air incorporation contact pin type SMP (Symmetrical Multi Processing) radio frequency coaxial connector which comprises an inner conductor, an outer conductor and an insulator fixed between the inner conductor and the outer conductor, wherein a uniform gap is arranged between the outer circumferential side surface of the insulator and the middle of the inner circumferential side surface of the outer conductor; the outer diameter of the insulator adapts to the outer diameter of the insulator of a jack type connector matched with the insulator; the outer diameter of the inner conductor adapts to the inner diameter of a jack of a jack type connector matched with the inner conductor; and the inner diameter of the outer conductor adapts to the outer diameter of a jack type connector matched with the outer conductor. The invention solves the technical problem of poor standing-wave ratio property of the traditional pin type SMP radio frequency coaxial connector and has the advantage of reducing the standing-wave ratio.
Description
Technical field
The present invention relates to a kind of SMP pin type radio frequency (RF) coaxial connector, relate in particular to a kind of air mixed pin type SMP radio frequency (RF) coaxial connector.
Background technology
Along with machine system miniaturization, modularization, high-frequency and high efficiency needs are installed, the SMP radio frequency (RF) coaxial connector is small and exquisite with himself volume, plug rapidly and characteristics such as frequency of utilization height obtain more and more widely application, the quality of its performance has fundamental influence to the performance of machine system.But the interface of existing pin type SMP connector adopts whole PTFE mediums to fill when layout setting, as shown in Figure 1, insulator 2 is arranged between outer conductor 3 and the inner wire 1, when connector and connector grafting, certainly have semidiameter, otherwise can not peg graft.Owing to there is semidiameter, will cause the standing-wave ratio performance index relatively poor, can not satisfy the demand of market to premium quality product.Therefore, the SMP pin type radio frequency (RF) coaxial connector of being badly in need of a kind of standing-wave ratio superior performance of appearance comes.
Summary of the invention
The present invention proposes a kind of air mixed pin type SMP radio frequency (RF) coaxial connector, it solves the technical problem of the standing-wave ratio poor performance of existing pin type SMP radio frequency (RF) coaxial connector.
Technical solution of the present invention is:
A kind of air mixed pin type SMP radio frequency (RF) coaxial connector, comprise inner wire 1, outer conductor 3 and be fixed on inner wire 1 and outer conductor 3 between insulator 2, its difference is: be provided with uniform gap 4 between the middle part of the excircle side of described insulator 2 and the inner periphery side of outer conductor 3; The external diameter of described insulator 2 adapts with the external diameter of the insulator 12 of the jack type connector that is mated; The external diameter of described inner wire 1 adapts with the internal diameter of the jack 11 of the jack type connector that is mated; The internal diameter of described outer conductor 3 adapts with the external diameter of the outer conductor 13 of the jack type connector that is mated.
The advantage that the present invention is compared with prior art had:
1, the present invention reduces the diameter transition between the insulator of the jack type connector of having cancelled insulator and being mated, and so just can not produce reflection, has reduced standing-wave ratio.
2, the present invention reduces the diameter transition between the jack of the jack type connector of having cancelled inner wire and being mated, and so just can not produce reflection, has reduced standing-wave ratio.
3, the present invention reduces the diameter transition between the outer conductor of the jack type connector of having cancelled outer conductor and being mated, and so just can not produce reflection, has reduced standing-wave ratio.

Fig. 2 is the structural representation of radio frequency (RF) coaxial connector of the present invention;
Fig. 3 is SMP jack type connector construction figure;
Fig. 4 is the annexation schematic diagram of pin type connector of the present invention and jack type connector;
Wherein: 1-inner wire, 2-insulator, 3-outer conductor, 4-gap, the jack of 11-jack type connector, the insulator of 12-jack type connector, the outer conductor of 13-jack type connector.
Embodiment
Be illustrated in figure 2 as structural representation of the present invention, comprise inner wire 1, outer conductor 3 and be fixed on inner wire 1 and outer conductor 3 between insulator 2,
In order to reduce the diameter transition between the insulator of the jack type connector of having cancelled insulator and being mated, the present invention is provided with uniform gap 4 between the middle part of the inner periphery side of the excircle side of insulator 2 and outer conductor 3.
Fig. 3 is SMP jack type connector construction figure; Comprise outer conductor 3 and jack 4 and be arranged on outer conductor 3 and jack 4 between insulator 2.
The pin type connector shown in Figure 4 and the annexation schematic diagram of jack type connector, wherein the formation gap of pin type connector between outer conductor and insulator is applicable to what the jack of jack type connector inserted, can guarantee that so not only jack type can well be connected with the pin type connector, and can guarantee that more the external diameter of insulator 2 and the external diameter of the insulator 12 of the jack type connector that is mated adapt, the external diameter of inner wire 1 adapts with the internal diameter of the jack 11 of the jack type connector that is mated, and the internal diameter of outer conductor 3 adapts with the external diameter of the outer conductor 13 of the jack type connector that is mated.
The size of the insulator of SMP pin type connector and jack type connector, outer conductor and inner wire adapts fully, does not have diameter transition, can not produce reflection, has effectively reduced standing-wave ratio.
