Description
Technical field
The utility model belongs to technical field of electric equipment, particularly relates to a kind of radio frequency (RF) coaxial connector.
Background technology
Radio frequency (RF) coaxial connector is installed in a kind of element on cable or on instrument, as transmission electrical connection or
The element of separation, the connector are same for communication and connection radio frequency in electronic equipment and similar electronic equipment institute adapted radio-frequency transmission line
Shaft cable, or coaxially and micro-strip, the coaxially connection between waveguide.Its plug portion is often mounted in cable socket, socket part
Often it is arranged on equipment fixed cell, the connection being also commonly used between two radio-frequency cables.General radio frequency (RF) coaxial connector includes
One shell, an insulator and an inner wire.After usual radio frequency (RF) coaxial connector is attached on equipment or instrument, due to environment
Factor, during long-term use, the hydrone in air can enter equipment or instrument internal by radio frequency (RF) coaxial connector,
The part of equipment or instrument internal is caused to get rusty, so as to influence the normal use of equipment or instrument；Usual radio frequency (RF) coaxial connector
Interior insulator is affected by temperature, and its change in size is also obvious, is easily caused steam and is entered in equipment.
At present, conventional water proof type radio frequency (RF) coaxial connector is all the slot pulling on inner wire and insulator, then by waterproof
Sealing ring is attached in the groove scratched, and finally the inner wire for installing sealing ring and insulator are encased in shell.Existing waterproof
Although radio frequency (RF) coaxial connector joint can play waterproof action, not only part difficulty of processing is big for such a connector, assembly process
Also it is comparatively laborious, and if when the machining tolerance of part is larger, assembling easily causes sealing ring distortion, and as a result joint just rises not
To the effect of waterproof.
Utility model content
The utility model proposes a kind of radio frequency (RF) coaxial connector, solves existing for water-proof structure of connector in the prior art
Defect.
What the technical solution of the utility model was realized in：
A kind of radio frequency (RF) coaxial connector, including shell, inner wire and insulator, shell leading portion are internally provided with described and led
Body, insulator are arranged between inner wire and shell endoporus, and the inner wire is pressed into the hole of the insulator from left to right, and
Both are connected with the sleeve for interting cable, one are provided with described sleeve pipe to be fitted close on the rear end of the shell
Sealing ring, pass through screw thread in described sleeve pipe and be connected a clamp nut.
Further, described sleeve pipe includes the leading portion and back segment surrounded by the tube wall with micro-elasticity, and the leading portion is in circle
Cylinder shape, back segment are in bell mouth shape.
Further, the second external screw thread is provided with described sleeve pipe, the second internal thread is provided with the back segment of the shell,
Described sleeve pipe is threadedly coupled shell on the back segment of shell.
Further, the distal opening edge of described sleeve pipe stretches out to form an annular rib, prevents clamp nut from taking off
Fall.
The tube wall of described sleeve pipe has micro-elasticity, is made of micro-elasticity material, including plastic, rubber etc..
Further, the difference of the external diameter in described sleeve pipe in the back segment of bell mouth shape its both ends open is 1-2mm.
Further, the internal diameter of the clamp nut is consistent with external diameter minimum on sleeve pipe.
In summary, the utility model has the advantage of：
Dough mixing machine of the present utility model is used and mask device, implements extruding to the sealing ring in sleeve pipe by clamp nut,
So as to realize sealing water-proof function, connection can be installed simply with easier screw-in clamp nut in the design of bell mouth shape, it is close
Envelope is reliable, good sealing effect, water resistance.
