Description
Technical Field
The utility model relates to a SMA connects technical field, specifically is SMA connects coaxial feeder.
Background
The SMA connector is a small-sized threaded connection coaxial connector with wide application, and has the characteristics of wide frequency band, excellent performance, high reliability and long service life, the SMA connector is suitable for connecting a radio frequency cable or a microstrip line in a radio frequency loop of microwave equipment and a digital communication system, and a coaxial cable is generally required to be used in the use process of an antenna, wherein the coaxial cable is a cable with two concentric conductors, and the conductor and a shielding layer share the same axis;
however, most of the existing SMA joints are made of brass, so that when the SMA joints are used outdoors, the SMA joints are easily corroded due to the fact that the outdoor environment is wet, and are in contact with air to be oxidized, the brass joints are generally not high in hardness and easy to deform in the assembling process, meanwhile, the SMA joints on the market are not provided with sealing rings, so that a good waterproof effect cannot be achieved, and the service life is short.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of prior art scheme, the utility model provides a SMA connects coaxial feeder.
The utility model provides a technical scheme that its technical problem adopted is: the SMA joint coaxial feeder comprises an SMA joint screw made of stainless steel and a coaxial feeder connected with the SMA joint screw, wherein the SMA joint screw is provided with a sealing ring in non-fixed connection with the SMA joint screw.
Preferably, the middle part of the SMA joint screw is provided with a signal transmission copper pipe.
Preferably, an insulating part for blocking is arranged between the signal transmission copper pipe and the SMA joint screw.
Preferably, the SMA joint screw is provided with a limit groove for mounting the seal ring.
Preferably, the sealing ring is in interference connection with the limiting groove.
Compared with the prior art, the beneficial effects of the utility model are that:
the SMA that stainless steel connects the screw can effectively avoid the outdoor environment humidity and arouse the corruption, difficult oxidation to hardness is high, is difficult for taking place to warp during the equipment, has increased substantially the life that SMA connects, and SMA connects the screw and is equipped with the sealing washer, can effectively improve the waterproof performance that SMA connects through setting up the sealing washer, does not receive the transmission influence during the transmission antenna signal.
Drawings
FIG. 1 is a schematic view of the present invention;
reference numbers in the figures:
the coaxial feed line comprises a coaxial feed line 1, an SMA joint screw 2, a sealing ring 3, a limiting groove 4, a transmission signal copper pipe 5 and an insulating part 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a SMA connects coaxial feeder, SMA joint screw 2 including stainless steel and with SMA joint screw 2 interconnect's coaxial feeder 1, stainless steel's SMA joint screw 2 can effectively avoid the outdoor environment humidity and arouse the corruption, difficult oxidation to hardness is high, is difficult for taking place to warp during the equipment, has increased substantially SMA connects's life, SMA joint screw 2 is equipped with non-fixed connection's sealing washer 3 with it, SMA joint screw 2's middle part is equipped with transmission signal copper pipe 5, because copper transmissibility is good, consequently transmission signal copper pipe 5 is the copper product, be equipped with the insulating part 6 that plays the separation effect between transmission signal copper pipe 5 and the SMA joint screw 2, insulating part 6 adopts the plastic material, can effectively avoid transmission signal copper pipe 5's transmission performance to receive harmful effects.
To sum up, stainless steel's SMA connects screw can effectively avoid the outdoor environment humidity and arouse the corruption, is difficult for the oxidation to hardness is high, is difficult for taking place to warp during the equipment, has increased substantially SMA connects life, and SMA connects the screw and is equipped with the sealing washer, can effectively improve SMA and connects waterproof performance through setting up the sealing washer, does not receive the transmission influence when transmitting antenna signal.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
