Abstract
The utility model relates to a radio frequency coaxial connector with reliable connection, which comprises a metal inner conductor, an insulation support, a packing washer, a metal outer conductor, a threaded sleeve and a clamping ring. The radio frequency coaxial connector with reliable connection is characterized in that a through hole for coaxial cables for inserting on the tail of the metal outer conductor is designed into a step through hole, the diameter Phi D2 on the tail end of the step through hole is 0.2 to 0.3mm bigger than the outer diameter of the penetrated coaxial cables, the diameter Phi D1 of the through hole on the other end is equal to the outer diameter of the coaxial cables, and the length ratio of the two through holes is about 2:1. When the radio frequency coaxial connector of the utility model is adopted, the coaxial performance of the cable and the connector can be guaranteed, signal loss can be reduced, stable and excellent electric performance indexes can be provided, normal transmission of radio frequency signals can be ensured, the coaxial cables and the radio frequency coaxial connector can be reliably connected, and the qualified rate of finished products can be greatly improved.
Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector of reliable connection, belongs to a kind of jockey, is specially adapted in the communication system of radiofrequency signal and power delivery.
Background technology
In the prior art, the employed radio frequency (RF) coaxial connector that connects the semihard cable of communication system, general main by metal outer conductor, insulation support, the metal inner wire forms jointly.After cable core and the welding of metal inner wire, push in the lump in the metal outer conductor.Accurately transmit for the assurance radiofrequency signal, the metal outer conductor of coaxial connector and the screen of cable need be connected reliably, adopt Welding Structure usually.Method is to open the hole at the afterbody of metal outer conductor, welding after cable is packed into.If it is big that open in the hole, when then welding scolding tin flow into too many and weld time longer, and cable tilts easily, with the connector disalignment, causes product electrical performance indexes variation.If it is little that open in the hole, scolding tin flows into insufficiently when then welding, and it is little that scolding tin effectively contains area, causes rosin joint, causes product failure.So open the method in hole at metal outer conductor afterbody, what no matter opened in the hole is big or little, operation all bothers during welding, scolding tin flows into situation and all needs weld time the workman to judge according to the experience of oneself, qualification to the operator is had relatively high expectations, and weld time is longer, and production efficiency is low, and difficult realization is produced in enormous quantities.
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 of reliable connection, by improvement to the metal outer conductor, solved cable and connector concentricity problem and when welding scolding tin flow into what problem, thereby provide a kind of production efficiency height, cost low, can be mass-produced, have the product electrical performance indexes simultaneously and stablize, connect reliable radio frequency (RF) coaxial connector.
Technical scheme
A kind of radio frequency (RF) coaxial connector of reliable connection, comprise metal inner wire 1, insulation support 2, sealing ring 3, metal outer conductor 4, swivel nut 5, collar 6, it is characterized in that: the via design that metal outer conductor 4 afterbody coaxial cables are inserted becomes step through-hole, the through-hole diameter Φ D2 of step through-hole tail end is greater than the external diameter 0.2～0.3mm that penetrates coaxial cable 9, the through-hole diameter Φ D1 of the other end equals the external diameter of coaxial cable 9, and the length ratio of two sections through holes is about 2 to 1.
The through-hole diameter Φ D2 of described step through-hole tail end is greater than the external diameter 0.23～0.28mm that penetrates coaxial cable 9.
The length ratio of described two sections through holes is about 2 to 1.2.
Beneficial effect
The radio frequency (RF) coaxial connector of a kind of reliable connection that the utility model proposes compared with prior art, the utlity model has following advantage:
1, adopt the utility model radio frequency (RF) coaxial connector, the assurance cable is coaxial with connector, has reduced losing of signal, provides and stablizes good electrical performance indexes, guarantees the normal transmission of radiofrequency signal;
2, coaxial cable and radio frequency (RF) coaxial connector can weld reliably, the stream tin of both having avoided the hole to cause greatly is too many, weld time the long short circuit problem that causes, the scolding tin of having avoided the hole to cause for a short time again effectively contains the problem of faulty soldering that the area introductory note rises, and has improved the qualification rate of finished product greatly.
3, stream tin amount is certain, can realize mechanized operation, adopts the automatic welding machine welding, has not only reduced the requirement to operator's qualification, has improved production efficiency simultaneously, has saved cost.Can realize producing in enormous quantities.
