Abstract
The invention relates to a radio frequency coaxial connector adapted to a semi-rigid cable. The connector comprises a metal inner conductor, an insulating support, a sealing ring, a metal outer conductor, a threaded insert and a retainer ring, and is characterized in that: a through hole into which a coaxial cable is inserted at the tail of the metal outer conductor is designed into a step-shaped through hole; the through hole diameter Phi D2 at the tail of the step-shaped through hole is 0.2 to 0.3mm more than an external diameter of the inserted coaxial cable; the through hole diameter Phi D1 at the other end is equal to the external diameter of the coaxial cable; and the length ratio of the two through holes is about 2:1. The radio frequency coaxial connector guarantees coaxiality of the cable and the connector, reduces the signal loss, provides stable and excellent electric performance indexes and guarantees normal transmission of radio frequency signals; and the coaxial cable can be reliably welded with the radio frequency coaxial connector, and the yield of finished products is greatly improved.
Description
Technical field
The present invention relates to a kind of radio frequency (RF) coaxial connector that connects the semihard cable, belong to a kind of jockey, be 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 present invention proposes a kind of radio frequency (RF) coaxial connector that connects the semihard cable, 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 that connects the semihard cable, 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
A kind of radio frequency (RF) coaxial connector that connects the semihard cable that the present invention proposes, compared with prior art, the present invention has the following advantages:
1, adopt radio frequency (RF) coaxial connector of the present invention, 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.
