Description
(1) technical field
The present invention relates to a kind of F type coaxial connectors.
(2) background technique
According to Japanese customers and market development needs, develops and connect applied to satellite TV set-top boxes and outdoor satellite antenna
The connector connect.It is shown by the investigation of private 6 company of BS, selects the user up to 38,000,000 of BS number, popularity rate reaches
About 7 one-tenth.Currently, if user needs to enjoy 4K audio visual effect, it is necessary to dedicated receiver and coaxial connecting line are bought, with 4K
It gradually promotes, market capacity is by further expansion.
The outer insulation diameter that 2C coaxial cable is defined in 3501 standard of Japanese customers JIS C is 2mm.Due to the cable screens
The outer diameter for covering aluminium foil is almost equal with the outer diameter of acupuncture needle tail end, if therefore conventional F connector does not do quarantine measures in assembling,
The outer conductor aluminium foil of 100% probability acupuncture needle and cable overlap joint and it is short-circuit.And conventional F-connector is not easy group in use
Dress, and the characteristic impedance of connector is generally lower than 75 ohm, influences the signal decaying and signal reflex of connecting line.To influence 4K
The clarity of TV.The nut in assembling of screw-type F is easy by being broken to plug-in unit deboost or separate with main body cover
And lead to performance failure.
(3) summary of the invention
The technical problem to be solved by the present invention is to overcome the above problem, a kind of ease of assembly, low loss are provided
F type coaxial connector.
For this purpose, the present invention takes following technical scheme:
A kind of F type coaxial connector, includes nut and hollow shell, and the shell is integrally formed by head tube and tail pipe；
Head tube adjacent end portion is equipped with annular groove, and the nut, which is inlayed by the stamping forming interior hook in end with head tube, to be flexibly connected；It is described
Close installation has dumbbell shaped insulator in head tube, and for the dumbbell shaped insulation subcenter through there is acupuncture needle, acupuncture needle tail portion extends to spiral shell
In cap, acupuncture needle head extends to dumbbell shaped insulator end；Inner connecting tube, the inscribed tube head and shell are equipped in the shell
Interference fit connection, the end of inner connecting tube are equipped with step, installation and electric cable foaming layer outer diameter isolated insulation of the same size, electricity
The inner conductor of cable extends to acupuncture needle inner hole through isolated insulation；Cable jacket is formed between the inner connecting tube tail portion and tail pipe
Accommodating chamber.
The acupuncture needle head is equipped with barb structure.
The inscribed pipe outer wall is equipped with progressive protrusion.
The outer shell outer wall corresponds to the sub- position of isolated insulation equipped with groove.
Reinforcing rib is used inside the nut, screw thread process has arrived nut bottom.
The acupuncture needle uses high-conductive metal material, and acupuncture needle surface uses gold-plated structure.
The invention has the following advantages that in 1, head tube close installation dumbbell shaped insulator, middle section wall thickness is smaller, gold
Needle can reduce the stress extruding to acupuncture needle when being inserted into, reduce assembling operation difficulty；2, of the same size with electric cable foaming layer outer diameter
Isolated insulation, overlaps coaxial cable shield aluminium foil with acupuncture needle while guaranteeing characteristic impedance consistency, avoid the present invention
The characteristic impedance of disclosed F type connector and coaxial cable mismatches and the risk of easily short circuit；3, pipe outer wall is inscribed equipped with progressive
Formula protrusion, increase and cable retention after cable outer conductor and sheath insertion, while avoiding being expressed to cable when tail pipe riveting
Dielectric and lead to impedance discontinuity, lead to the loss of signal；4, there are the ring channel structures inlayed with nut in metal shell front end,
Head tube and tail pipe, which are integrally formed, is used for carrying power cables sheath and outer conductor, which makes connector that need to only pre-install dumbbell shaped when assembling
Inside the shell, connector is disposed vertically the rear assembling for only needing a punching press that connector can be completed for insulator and inner connecting tube.It reduces
Assembling procedure reduces cost of labor；5, it is outer to increase injection molding for the groove structure that outer shell outer wall corresponds to the sub- position setting of isolated insulation
The retentivity of mould and connector；6, the screw thread process of nut has arrived nut bottom, increases the contact interference area with female end, from
And the retentivity of female end and connector is increased, F-type connector disclosed by the invention is effectively ensured not by cable self weight and wink
Between pulling force cause to fall off or electrical property degrades, guarantee the reliability of connection；Reinforcing rib is used inside nut, keeps connector torsion big
It in 5N/M, effectively prevents overexertion when operator assembles and damages connector, while the reinforcing rib is not assembled with shell
Interference, thus ensure that nut rotation when it is smooth and do not issue abnormal sound in an assembling process；7, acupuncture needle head is equipped with hangnail knot
Structure prevents coaxial cable because self weight causes inner conductor to be pullled acupuncture needle by stress, leads to poor contact after so that acupuncture needle is bounced back；Acupuncture needle is adopted
Signal reflex is reduced with high-conductive metal material and gold-plated reduction contact impedance；8, isolated insulation using Teflon material and with
Electric cable foaming layer outer diameter is in the same size, and being mounted between acupuncture needle and cable prevents cable aluminum foil and acupuncture needle from overlapping short circuit；9, shell
Interior inner connecting tube prevents shell stress during riveting from squeezing coaxial cable foaming layer, so that characteristic impedance is discontinuously to increase
Plus signal loss.
