Abstract
The invention relates to an SMA radio frequency coaxial connector, comprising a shell (1), an insulator (2) and an inner conductor (3), wherein the insulator (2) is arranged in the shell (1); and the inner conductor (3) is arranged in the insulator (2). The SMA radio frequency coaxial connector further comprises an adhesive filling hole (4) which is arranged on the outer surface of the inner conductor (3) and provided with at least one barb (5) and radially penetrates through the shell (1) and the insulator (2); the diameter of the adhesive filling hole (4) is slightly greater than that of the inner conductor (3); and an potting adhesive (6) is arranged in the adhesive filling hole (4). The invention solves the technical problem of poorer standing-wave ratio performance or poorer reliability of the traditional connector and has the advantages of enhanced standing-wave ratio performance and high reliability.
Description
Technical field
The present invention 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 problem to be solved in the present invention 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 invention 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 comprises that also the outer surface that is arranged on inner wire 3 is provided with at least one hangnail 5 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 invention is:
1, improves the standing-wave ratio performance.Inner wire of the present invention 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 glue filling opening of the present invention 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 present invention 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.

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 present invention 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 present invention 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 comprises that also the outer surface that is arranged on inner wire (3) is provided with at least one hangnail (5) 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).
