Abstract
The utility model relates to an SMA radio-frequency coaxial connector comprising a shell (1), an insulator (2) arranged inside the shell (1) and an inner conductor (3) arranged in the insulator (2), as well as at least one barb (5) arranged at the outer surface of the inner conductor (3) and a glue pouring hole (4) radially penetrating through the shell (1) and the insulator (2); the diameter of the glue pouring hole (4) is lightly larger than that of the inner conductor (3); and the glue pouring hole (4) is internally provided with pouring glue (6). The SMA radio-frequency coaxial connector solves the technical problems of poorer standing wave performance or poorer reliability of the existing connector, and has the advantages of improving the standing wave performance, being high in reliability and the like.
Description
Technical field
The utility model relates to a kind of SMA radio frequency (RF) coaxial connector.
Background technology
SMA type radio frequency (RF) coaxial connector is present most widely used a kind of radio frequency (RF) coaxial connector, and its superior performance, volume is small and exquisite, connection is reliable.But, present SMA type radio frequency (RF) coaxial connector, as shown in Figure 1, insulator comes off easily and causes that structural reliability is relatively poor, the standing wave poor-performing in high and low temperature environment, and the target of its performance distance user expectation still has one section gap, also needs further raising.Under this background, be badly in need of occurring the more superior SMA connector of a kind of standing-wave ratio performance and satisfy this demand.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of SMA radio frequency (RF) coaxial connector, and it has solved existing connector and has used standing-wave ratio poor-performing or the relatively poor technical problem of reliability.
Technical solution of the present utility model is:
A kind of SMA radio frequency (RF) coaxial connector, comprise housing 1, be arranged at the insulator 2 of housing 1 inboard and be arranged at inner wire 3 in the insulator 2, it is characterized in that: described SMA radio frequency (RF) coaxial connector also comprises at least one hangnail 5 of the outer surface that is arranged on inner wire 3 and radially connects housing 1 and the glue filling opening 4 of insulator 2; The slightly larger in diameter of described glue filling opening 4 is in the diameter of inner wire 3; Be provided with casting glue 6 in the described glue filling opening 4.
Technique effect of the present utility model is:
1, improves the standing-wave ratio performance.The utility model inner wire is connected to one by hangnail and insulator, and hangnail so the hangnail size can be very short, has reduced the impedance section of not matching because only need tangle insulator can prevent the inner wire play.And prior art is because adopt casting glue to fix, guarantee that inner wire can play, must stay enough enough glue grooves, promptly open glue groove in the conductor, casting glue is injected into inner wire from glue filling opening and opens on the glue groove, and fluting can make that the impedance section of not matching is longer in the conductor.The slightly larger in diameter of the utility model glue filling opening is in the diameter of inner wire, and casting glue passes from the inner wire outer surface, makes inner wire need not open glue groove, does not influence the inner wire diameter, and impedance remains unchanged, and has promoted the standing-wave ratio performance of product.
2, reliability height.The utility model is in by hangnail fixed insulation and inner wire, adopt casting glue stationary housing and insulator, and the slightly larger in diameter of glue filling opening is in the diameter of inner wire, thereby housing, insulator and inner wire three are fixed up, under the prerequisite that does not influence the standing wave performance, played fixing effect again, with adopt the mode of close-fitting to compare between original insulator and the shell, being connected between insulator and the shell is more reliable.

Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model inner wire and hangnail;
Reference numeral is as follows: 1-housing, 2-insulator, 3-inner wire, 4-glue filling opening, 5-hangnail, 6-casting glue, 7-glue groove.
Embodiment
Referring to Fig. 2-3, the utility model is a kind of SMA radio frequency (RF) coaxial connector, include housing 1, be arranged at housing 1 inboard insulator 2, be arranged at the inner wire 3 in the insulator 2 and radially connect housing 1 and the glue filling opening 4 of insulator 2, in glue filling opening 4, be provided with casting glue 6, wherein the slightly larger in diameter of glue filling opening 4 is in the diameter of inner wire 3, and insulator 2 is connected with inner wire 3 by hangnail 5.Specifically, hangnail 5 can be arranged at the outer surface of inner wire 3.The utility model also improves the standing-wave ratio performance, thereby improves the quality of products when fixing by hangnail 5 and casting glue.
Claims (1)
1. SMA radio frequency (RF) coaxial connector, comprise housing (1), be arranged at the inboard insulator (2) of housing (1) and be arranged at the interior inner wire (3) of insulator (2), it is characterized in that: described SMA radio frequency (RF) coaxial connector also comprises at least one hangnail (5) of the outer surface that is arranged on inner wire (3) and radially connects housing (1) and the glue filling opening (4) of insulator (2); The slightly larger in diameter of described glue filling opening (4) is in the diameter of inner wire (3); Be provided with casting glue (6) in the described glue filling opening (4).
