Abstract
The invention discloses an F-type quick connection-peg used for radio frequency and coaxial-cable. The F-type quick connection-peg comprises an F-type mother head, a cavity which is connected with the F-type mother head. The cavity is connected with a pipe end which is matched with the coaxial-cable. An insulator is arranged at the bottom of the cavity next to the pipe end, a flower basket used for autonomously adjusting the elasticity of insertion and extraction force of the F-type mother head on the inner circumference of the cavity, a copper sheet is arranged on the outer side of the insulator inside the cavity. An end surface of the F-type mother head is contacted with the copper sheet. The F-type quick connection-peg is capable of reducing the leakage of high frequency signals and meeting demands of shielding and declining.
Description
Technical field
The present invention relates to radio frequency and coaxial fitting.
Background technology
European Union had promulgated " BS EN 60966-2-6-2009 " standard in 2009, and comprising radio frequency and co-axial cable component, radio frequency and TV receiver cable assembly---the closed specification of IEC 61169-24 connector, frequency range covers 0 ~ 3000 MHZ.IEC 61169-24 connector is commonly called as the F head, comprises F type quick connector and the slow connection-peg of F type.Emphasized the shielding attenuation of cable assembly in " BS EN 60966-2-6-2009 ", the cable assembly of CLASS A level will reach following standard: in 30 MHZ ~ 1000 MHZ scopes, shielding attenuation is greater than 95dB; In 1000 MHZ ~ 3000 MHZ scopes, shielding attenuation is greater than 85dB.
Shown in Figure 1, the structure of F type quick connector commonly used comprises at present: F type female 1, the cavity 2 that matches with F type female 1, offer equably four in order to the groove 21 of autonomous adjustment F type female 1 plug power on the inner peripheral surface of cavity 2, be provided with clip 22 on the outer circumference surface of cavity 2 ports, after F type female 1 was inserted cavity 2, clip 22 tightened up F type female 1 and gets loose preventing; Cavity 2 be connected with pipe tail 5 that the coaxial wire body coordinates, during use, pipe tail 5 need be enclosed within the braiding of coaxial wire body, punching press contacts seamless after shrinking.Be provided with 30 degree angles between tail 5 at cavity 2 and pipe and extend the Taper Pipe 4 of transition, be provided with insulator 3 in cavity 2 bottoms near Taper Pipe 4.
There is following shortcoming in the F type quick connector of said structure: several grooves on ⑴ cavity inner peripheral surface, exist serious signals leakiness in high-frequency range, and can't satisfy the shielding attenuation requirement; ⑵ adopt the Taper Pipe transition between cavity and pipe tail, insulator is difficult to the location.
Summary of the invention
The purpose of this invention is to provide a kind of F type quick connector that can reduce the high-frequency signal leakage, satisfy the shielding attenuation requirement.
For achieving the above object, the present invention has adopted following technical scheme.
A kind of F type quick connector comprises: F type female, with the cavity that F type female matches, cavity be connected with pipe tail that the coaxial wire body coordinates, be provided with insulator at the cavity bottom near the pipe tail; Be characterized in: be provided with the flexible gaily decorated basket in order to autonomous adjustment F type female plug power on the inner peripheral surface of cavity, be provided with to locate the gear lip of the gaily decorated basket on the inner peripheral surface of cavity port, also be provided with copper sheet be positioned at insulator in cavity outside, the two ends of the gaily decorated basket are fixed between gear lip and copper sheet, after F type female was inserted cavity, the end face of F type female contacted with copper sheet.
Further, aforesaid a kind of F type quick connector, wherein, the described gaily decorated basket is shaped by the copper strip roll circle that the middle part has several inwardly protruded arc ribs.
Further, aforesaid a kind of F type quick connector, wherein, cavity is connected by the right angle transition body with the pipe tail, and insulator is positioned on the base plane of right angle transition body.
Beneficial effect of the present invention: use F type quick connector of the present invention, can reduce high-frequency signal and leak, satisfy the shielding attenuation requirement.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, a kind of F type quick connector of the present invention is further described.
Shown in Figure 2, a kind of F type quick connector of the present invention comprises: F type female 1, with the cavity 2 that F type female 1 matches, cavity 2 be connected with pipe tail 5 that the coaxial wire body coordinates, be provided with insulator 3 in cavity 2 bottoms near pipe tail 5; Cavity 2 is connected by right angle transition body 9 with pipe tail 5, and insulator 3 is positioned on the base plane 91 of right angle transition body 9, and contrast locating is more accurate like this; Be provided with the flexible gaily decorated basket 7 in order to autonomous adjustment F type female 1 plug power on the inner peripheral surface of cavity 2, referring to Fig. 3, shown in Figure 4, the described gaily decorated basket 7 is shaped by the copper strip roll circle that the middle part has several inwardly protruded arc ribs.Be provided with to locate the gear lip 6 of the gaily decorated basket 7 on the inner peripheral surface of cavity 2 ports, be positioned at insulator 3 outsides and also be provided with copper sheet 8 in cavity 2, the two ends of the gaily decorated basket 7 are fixed between gear lip 6 and copper sheet 8, after F type female 1 is inserted cavity 2, the end face 11 of F type female 1 contacts with copper sheet 8, can increase like this contact area, minimizing contact resistance and high-frequency signal leakage with F type female 1.
Use F type quick connector of the present invention, increased the contact area with F type female 1, reduced contact resistance; Reduced simultaneously high-frequency signal leakage, satisfy the shielding attenuation requirement.
