Description
Technical Field
The utility model relates to a radio frequency coaxial connector makes technical field, especially relates to a radio frequency coaxial connector screw.
Background
In the whole radio frequency communication, the following frequencies are mainly included: transmission frequency, reception frequency, intermediate frequency, and baseband frequency. The baseband frequency is the signal frequency used to modulate the data. And a good communication effect can be obtained by applying a high-quality intelligent demodulator in a downlink baseband converter. If the leakage of the local pll and rf device is small enough, the dc offset of the baseband can be minimized.
The existing radio frequency coaxial connector fixing screw is generally directly fixed, a mechanical wrench is adopted for fixing, the phenomenon that the screw or a fixed radio frequency connector is damaged due to large fixing force is prone to occurring, meanwhile, when the connection position of the radio frequency coaxial connector is subjected to large force, the radio frequency coaxial connector or a connecting wire is likely to be aged, and then the radio frequency coaxial connector screw is damaged in an accelerated mode, and the radio frequency coaxial connector screw is designed aiming at the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a radio frequency coaxial connector screw possesses convenient dismantlement and the stationary force is even, all has certain cushioning effect's advantage, has solved radio frequency coaxial connector set screw and has generally the snap-on, when radio frequency coaxial connector junction received great power, probably caused radio frequency coaxial connector or connecting wire ageing, and then the problem of damage with higher speed.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a radio frequency coaxial connector screw, includes spacing shell, screw, spacing shell cover is established on the screw, the holding tank that holds the nut is seted up to spacing shell top, the spring groove has been seted up to the holding tank bottom, the through-hole has been seted up to spring groove bottom, the through-hole top is provided with the spacing ring, the screw includes screw cap portion, post portion, the cover is equipped with reset spring on the post portion between screw cap portion and the spacing ring.
Further, the lower end of the column part is provided with a chamfer.
Furthermore, the outer side of the lower end of the limiting shell is provided with a limiting groove in a surrounding mode.
Furthermore, the lower part of the limiting shell is provided with anti-skid grains.
Further, the diameter of the lower half section of the upper column part of the screw is larger than that of the upper half section.
Furthermore, the limiting shell is made of plastic materials.
Compared with the prior art, the utility model beneficial effect who has is:
1. the limiting groove at the lower end of the limiting shell is fixed, then the screw is screwed so that the nut compresses the return spring, thereby achieving the effect of fixing the limiting shell and the radio frequency device, and the added return spring can play a role of buffering, so that the electric wrench is prevented from damaging the screw or the radio frequency fixer;
2. the chamfer of the lower end of the added column part can play a role in quick positioning when being fixed, and meanwhile, when the joint of the radio frequency connector and the lead wire is fixed, the device can be prevented from being damaged when being subjected to large force, and the buffer prevention effect can be played.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a schematic diagram of a half-section structure of a radio frequency coaxial connector screw according to the present invention;

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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 work belong to the protection scope of the present invention.
Referring to fig. 1-2, a radio frequency coaxial connector screw, includes spacing shell 2, screw 3, spacing shell 2 cover is established on screw 3, the holding tank that holds the nut is seted up on spacing shell 2 top, the spring groove has been seted up to the holding tank bottom, the through-hole has been seted up to spring groove bottom, the through-hole top is provided with the spacing ring, screw 3 includes screw cap portion, post portion, the cover is equipped with reset spring 1 on the post portion between screw cap portion and the spacing ring.
The lower end of the column part is provided with a chamfer.
The outer side of the lower end of the limiting shell 2 is provided with a limiting groove in a surrounding mode, and then a limiting bulge is formed and is of a dovetail-shaped structure.
The lower part of the limiting shell 2 is provided with anti-skid grains for increasing friction force.
The diameter of the lower half section of the upper column part of the screw 3 is larger than that of the upper half section.
The limiting shell 2 is made of plastic materials.
During the use, it is fixed with the spacing groove of 2 lower extremes of spacing shell, then screw 3 and make nut compression reset spring 1, thereby reach the effect of fixed spacing shell 2 and radio frequency ware, and the reset spring 1 of joining can play the cushioning effect, prevent that electric spanner from damaging the screw, or damage the radio frequency fixer, the chamfer of the post portion lower extreme of joining can play the function of quick location when fixed, simultaneously when the junction of fixed radio frequency connector and lead line, the damaged condition appears when can prevent that the device from receiving the big power, can play the effect of preventing buffering.
