Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector, belongs to a kind of coaxial cable jockey.
Background technology
Radio frequency (RF) coaxial connector is mainly used to realize the switching and the transmission of radiofrequency signal, is widely used in fields such as communication system, microwave measurement system, instrument and meter.Radio frequency (RF) coaxial connector is made up of three parts of the dielectric between shell, inner wire and shell and the inner wire; Function by its realization can comprise kinds such as connecting cable connector, microband connector, adapter.
Connecting cable connector is mainly used in radio frequency coaxial-cable and is connected, realize the transmission of signal, radio frequency coaxial-cable is made up of heart yearn, screen and insulating barrier, connector is exactly that cable core is connected with the connector inner wire with being connected of cable, cable shield is connected with connector shell, also to guarantee the connectivity of characteristic impedance during connection, to guarantee the quality of signal transmission.
Connect the cable connector structure as shown in Figure 1: cable core 5 adopts the soldering mode to be connected with connector inner wire 1; Cable shield 7 is crimping modes with the connected mode of connector shell 3, being about to cable shield 7 is contained between connector shell 3 and the metal sleeve 4, with instrument metal sleeve 4 crimping are deformed into six sides then, thereby make cable shield 7 clamped fixing, with cable shield 7 and connector shell 3 clampings together, 2 and 6 represent the dielectric of connector and the insulating barrier of cable respectively.
This structure attaching is convenient, does not need special equipment, thereby can reach place operations such as building site, machine station in the open air.But big shortcoming is arranged simultaneously: promptly when crimping metal sleeve 4, cable shield 7 also be crimped extended elongated, thereby coaxial cable is moved (dextrad among the last figure) side backward, drive cable core 5 motion backward together, because connector inner wire 1 welds together with cable core 5 in advance, inner wire 1 is also just being driven to contract backward and is being moved, the shortening phenomenon of the connector of industry theory that Here it is, this in addition structure connector institute distribution cable all is a flexible cable, in use, cable shield 7 still has the elongated phenomenon that stretches, connector inner wire 1 also can further contract backward, it can make the interface location of inner wire 1 substantial deviation connector, makes connector inner wire 1, cable core 5, cable insulation 6 (cut cable) all backward contracts and moves, thereby has influence on the connection reliability of connector.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, the utility model proposes a kind of radio frequency (RF) coaxial connector, by to the isostructural improvement of connector shell, inner wire is carried out clamping, thereby eliminate the shortening phenomenon of inner wire, improve the reliability of connector.
Technical scheme
A kind of radio frequency (RF) coaxial connector, comprise inner wire 1, dielectric 2 and connector shell 3, it is characterized in that comprising that afterbody is provided with the inner wire 1 of a boss 9, is first dielectric 2.1 of groove structure and dielectric 2 that second dielectric 2.2 is formed, is formed connector shell 3 and nut 8 by first connector shell 3.1 and second connector shell 3.2 by an end; Inner wire 1 boss 9 is positioned at the joining place of first dielectric 2.1 and second dielectric 2.2, and boss one end of second connector shell 3.2 inserts the tail end of first connector shell 3.1, and the flank of nut 8 is connected with the flank of first connector shell 3.2; The boss of the end face of nut 8 and second connector shell 3.2 matches, and the inner groovy of second dielectric 2.2 and second connector shell 3.2 matches.
Be connected end face at nut 8 with second connector shell 3.2 and be provided with pad.
The size at described nut 8 flank places be that second connector shell 3.2 inserts first connector shell, 3.1 formed spaces and matches.
Beneficial effect
The radio frequency (RF) coaxial connector that the utility model proposes by to the isostructural improvement of connector shell, carries out clamping to inner wire, thereby eliminates the shortening phenomenon of inner wire, improves the reliability of connector.The utility model has kept the advantage that existing connector attaching is convenient, can reach place operations such as building site, machine station in the open air, has overcome the shortening phenomenon of connector simultaneously, has guaranteed the reliability that signal connects.

Embodiment
Now in conjunction with the embodiments, accompanying drawing is further described the utility model:
Present embodiment as shown in Figure 2, on the basis of original crimping structure connector, see among Fig. 1: cable shield 7 is contained between connector shell 3 and the metal sleeve 4, with instrument metal sleeve 4 crimping is deformed into six sides then, thereby make cable shield 7 clamped fixing.Afterbody design boss 9 (as Fig. 7) at inner wire 1, dielectric is divided into two bodies, first dielectric 2.1) and second dielectric 2.2, make it can clamp inner wire 1, simultaneously connector shell is made two body structures, first connector shell 3.1 and second connector shell 3.2, make it can clamp first dielectric 2.1 and second dielectric 2.2, link together with the attaching nut 8 and first connector shell 3.1 at last, second connector shell 3.2 is fixed.The boss of the end face of nut 8 and second connector shell 3.2 matches, and the inner groovy of second dielectric 2.2 and second connector shell 3.2 matches.
First dielectric 2.1 is seen Fig. 3, and second dielectric 2.2 is seen Fig. 4, and first connector shell 3.1 is seen Fig. 5, and second connector, 3.2 structures are seen shown in Figure 6.
Be connected end face at nut 8 with second connector shell 3.2 and be provided with pad.
The size at described nut 8 flank places be that second connector shell 3.2 inserts first connector shell, 3.1 formed spaces and matches.
Because connector inner wire 1 tightly clamped by first dielectric 2.1 and second dielectric 2.2, so when the cable shield stretching, extend when elongated, connector inner wire 1 (cut cable) backward contracts and moves.
