The problem of among the prior art the easy fracture of cable shield layer lead to signal transmission effect poor is solved, the reliability of connector with cable junction has been improved. Can be applied to communication, radio equipment and the technical field such as instrument and automatic control of high reliability.
Description
Technical field
The utility model belongs to radio frequency (RF) coaxial connector field, is related to a kind of Miniature RF for connecting flexible cable coaxially to connect
Connect device.
Background technology
Connector is used to connect flexible cable.In the prior art, using crimp connector, the connector is by crimping phase
The crimping position answered, makes connector outer conductor be in close contact with cable shield using deformation, realizes connector outer conductor with electricity
The connection of cable screen layer.But, cable is bent repeatedly in use, and contact site is acted on by frictional force, the forced section
Partial volume easily causes shielding fault rupture, causes loose contact, influences signal transmission, it is impossible to meets and requires.
Utility model content
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided a kind of to connect the small-sized of flexible cable
Radio frequency (RF) coaxial connector.Solve the problems, such as that cable shield is easily broken off causing signal transmission effect poor in the prior art, carries
The reliability that connector high is connected with flexible cable.
The purpose of this utility model is solved by the following technical programs：
This small RF coaxial connector device for connecting flexible cable, including shell, are provided with insulator in shell,
Inner wire is inserted with insulator, the opening for welding also is provided with shell, one end of inner wire is in opening, on shell also
It is provided with cable jack.
Further, the features of the present invention is also resided in：
One end in opening of wherein inner wire is set to weld cup, and inner wire connects with the heart yearn of the cable for being connected
Connect.
The opening for being wherein used to weld is the first welding opening and the second welding opening that are opened up on shell, the one of inner wire
End is in the first welding opening.
Wherein cable jack is stepped hole.
Wherein housing exterior is also cased with bushing, the first welding of bushing parcel opening.
Wherein shell is connected with the screen layer of the cable for being connected.
The first draw-in groove and the second draw-in groove are wherein provided with the outer ring of shell.
Sealing ring is provided with wherein the first draw-in groove, snap ring is provided with the second draw-in groove.
The outside of wherein shell is also cased with swivel nut, and swivel nut passes through snap ring and cage connection.
The beneficial effects of the utility model are that insulator wraps up inner wire so that inner wire is not directly contacted with shell, outward
The first welding opening is provided with shell, one end of inner wire is set to weld cup, facilitates inner wire and directly welded with cable core, the
Two welding openings facilitate the direct welding of screen layer and shell.
Further cable jack is set to stepped hole, facilitates the classification insertion of cable core and screen layer, and
Effectively prevent cable and shell friction, it is to avoid phenomenon of rupture.
The first welding opening further is wrapped up using bushing, effectively prevent that the impedance mismatch of connector from causing is anti-
Penetrate increase.
The parts such as sealing ring, snap ring and swivel nut are further set, can seal shell and its internal being in
And the state of fastening, the parts of enclosure are protected, improve the reliability and stability of connector.
