Abstract

A novel connecting structure of a radio frequency coaxial connector of a thin cable comprise an inner conductor and an outer conductor, as well as a first insulator arranged inside the outer conductor and a second insulator which is adjacent to the first insulator and placed outside the first insulator, wherein the first insulator is arranged inside the second insulator; the inner conductor, inner holes of the first insulator and the outer conductor are superimposed to form a filling port; the filling port adopts an epoxy resin filling and packing mechanism; the size of the inner hole of the second insulator is equal to that of the core wire of the thin cable so as to centralize the core wire and ensure the core wire not to axially move; and the shielding layers of the outer conductor (3) and the thin cable adopt a welding mechanism. The novel connecting structure provided by the utility model has the advantage of preventing a thin cable core wire from breaking and loosening.

Description

The novel attachment mechanism of a kind of radio frequency (RF) coaxial connector of Thin cable

Technical field

The utility model relates to a kind of attachment mechanism of Thin cable, is specifically related to a kind of radio frequency cable of the about 1mm thickness of radio frequency (RF) coaxial connector novel attachment mechanism, especially diameter of Thin cable,

Background technology

Radio frequency (RF) coaxial connector is applied to machine system widely, and the quality of its performance has fundamental influence for the working stability of machine system, particularly the machine system of complex circuit; Search very loaded down with trivial details tired list in case go wrong, radio frequency (RF) coaxial connector in the market is when working in abominable vibration environment; Because the heart yearn of Thin cable is approximately 0.3mm; If frequent standing shakes, heart yearn very easily ruptures, and causes signal interruption.

The utility model content

In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of novel attachment mechanism of radio frequency (RF) coaxial connector of Thin cable, has to prevent fracture of Thin cable heart yearn and loosening advantage.

For achieving the above object, the utility model adopts following technical scheme to be:

The novel attachment mechanism of a kind of radio frequency (RF) coaxial connector of Thin cable; Comprise inner wire, outer conductor 3; Also comprise first insulator 1 that is arranged in the outer conductor 3 and adjacent with first insulator 1 and place the second outer insulator 2 of first insulator 1; First insulator 1 is arranged on the inside of second insulator 2, and the overlapping back of the endoporus of inner wire, first insulator 1 and outer conductor 3 forms filling exit 4.

Said filling exit 4 adopts epoxy resin can packaging mechanism.

The size of said second insulator, 2 endoporus and the equal and opposite in direction of Thin cable heart yearn are used to set upright heart yearn, guarantee that heart yearn axial motion can not take place.

The screen of said outer conductor 3 and Thin cable adopts welding mechanism.

Compare with prior art, the utlity model has following advantage:

1) the utility model first insulator 1 pack into outer conductor 3 back with epoxy resin inner wire, first insulator 1 and outer conductor 3 can epoxy resin together; After treating that the epoxy resin cooling is solidified; Welding Thin cable and outer conductor, after assurance heart yearn and inner wire welding were good, front end was fixed; Loosening and the axial motion phenomenon of pullling can not occur, guarantee that heart yearn is connected firmly with inner wire.

2) size of second insulator, 2 endoporus is the size of cable core, is used to set upright heart yearn; Prevent to vibrate when violent, the Thin cable heart yearn is done the tangential reciprocating motion of core section, and protection Thin cable heart yearn is not done radially and rocked.

3) screen of afterbody outer conductor 3 and Thin cable adopts welding mechanism; Guarantee that the rear end fixes; Prevent that heart yearn from outwards tearing, the inevitable dielectric in the aperture of other second insulator 2 less than Thin cable, front and back clamp second insulator 2; Inner wire can not move backward, so heart yearn more axial motion can not take place.

Embodiment

As shown in Figure 2; The novel attachment mechanism of the radio frequency (RF) coaxial connector of a kind of Thin cable of the utility model; Comprise inner wire, outer conductor 3, also comprise first insulator 1 that is arranged in the outer conductor 3 and adjacent with first insulator 1 and place first insulator, 1 outer second insulator, 2, the first insulators 1 to be arranged on the inside of second insulator 2; The overlapping back of the endoporus of inner wire, first insulator 1 and outer conductor 3 forms filling exit 4; Said filling exit 4 adopts epoxy resin can packaging mechanism, and the size of second insulator, 2 endoporus and the equal and opposite in direction of Thin cable heart yearn are used to set upright heart yearn; Guarantee that heart yearn axial motion can not take place, the screen of outer conductor 3 and Thin cable adopts welding mechanism.

The attaching principle of the novel attachment mechanism of radio frequency (RF) coaxial connector of a kind of Thin cable of the utility model is: with second insulator 2 outer conductor of packing into, and the heart yearn of the Thin cable that will strip in advance, pass outer conductor 3 successively; Second insulator 2, put on heart yearn after, begin to weld Thin cable heart yearn and inner wire; After welding is accomplished, with first insulator 1 pack into outer conductor, fixedly heart yearn; Again epoxy resin is poured into filling exit 4, first insulator 1, inner wire and outer conductor is encapsulated through epoxy resin together, treat the epoxy resin adhesive curing after; Welding Thin cable screen and afterbody outer conductor 3, fixing Thin cable prevents that Thin cable from doing axially to pull motion.
