Abstract
The present utility model discloses a radio frequency coaxial connector which belongs to the coaxial connector technology field. The radio frequency coaxial connector comprises a pin, a shell, and a thread sleeve, the pin is arranged in the middle of the sleeve, the middle part of the pin is propped on the inner wall of the shell after passing through an insulator, the thread sleeve is connected with the front end of the shell through a screw thread and a clamp ring, a crimping sleeve is sleeved on the rear part of the shell, the tail part of the pin is stretched out from the insulator, a gap insulated by an air medium is formed between the inner wall of the shell and the tail part of the pin, and the outer wall of the tail part of the pin is wrapped by an insulating medium layer. The outer wall of the tail part of the pin of the radio frequency coaxial connector is wrapped by the insulating medium layer, the gap between the insulating medium layer and the shell is an air insulating layer, thus double insulation is formed between the tail part of the pin and the inner wall of the shell, thus materials are saved, and the insulation performance is greatly increased.
Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector, belongs to the coaxial connector technical field.
Background technology
Existing radio frequency (RF) coaxial connector comprises contact pin, shell and swivel nut, contact pin is positioned at the center of shell, the middle part of contact pin is supported on the inwall of shell by insulator, swivel nut is connected the front end of shell by snap ring, the rear sleeve of shell is equipped with pressure welding case, the afterbody of contact pin stretches out from insulator, and and the inwall of shell between leave gap by the air dielectric insulation.
The weak point of existing radio frequency (RF) coaxial connector is: only by the air dielectric insulation, the big more then insulation effect in the gap between contact pin afterbody and the outer casing inner wall is good more between the inwall of contact pin afterbody and shell.For improving insulation effect, the diameter of shell afterbody need be done greatly, not only waste material has increased cost, and insulation property are general.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of radio frequency (RF) coaxial connector is provided, and insulate by blending agent between contact pin afterbody and the outer casing inner wall, not only save material, and insulation property is better.
For solving above technical problem, a kind of radio frequency (RF) coaxial connector provided by the utility model, comprise contact pin, shell and swivel nut, described contact pin is positioned at the center of described shell, the middle part of contact pin is supported on the inwall of described shell by insulator, described swivel nut is connected the front end of described shell by screw thread and snap ring, the rear sleeve of described shell is equipped with pressure welding case, the afterbody of described contact pin stretches out from described insulator, and and leaving the gap of insulating between the inwall of described shell by air dielectric, the afterbody outer wall of described contact pin is coated with insulating medium layer.
With respect to prior art, the utility model has been obtained following beneficial effect: the afterbody outer wall of contact pin is coated with insulating medium layer, gap between insulating medium layer and the shell is an air insulating layer, between contact pin afterbody and outer casing inner wall, formed double insulation like this, need not to do shell very big, not only save material more, and it is a lot of that insulation property are improved.
Description of drawings
Fig. 1 is the structural representation of the utility model radio frequency (RF) coaxial connector.
Fig. 2 is the structural representation of contact pin in the radio frequency (RF) coaxial connector.
Among the figure: 1 contact pin; 2 shells; 3 swivel nuts; 4 insulators; 5 pressure welding cases; 6 snap rings; 7 sealing rings; 8 insulating medium layers.
Embodiment
As shown in Figures 1 and 2, radio frequency (RF) coaxial connector of the present utility model comprises contact pin 1, shell 2 and swivel nut 3, contact pin 1 is positioned at the center of shell 2, the middle part of contact pin 1 is supported on the inwall of shell 2 by insulator 4, swivel nut 3 is connected the front end of shell 2 by screw thread and snap ring 6, is provided with sealing ring 7 between swivel nut inwall and the shell 2.The rear sleeve of shell 2 is equipped with pressure welding case 5, and the afterbody of contact pin 1 stretches out from insulator 4, and the afterbody outer wall of contact pin 1 is coated with insulating medium layer 8, leaves the gap as air insulating layer between insulating medium layer 8 and the shell 2.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
Claims (1)
