Abstract
The utility model discloses a straight assemble structure of a RF coaxial semirigid cable and relates to a plug assembly, an inserting needle and a semirigid coaxial cable; one end of the plug assembly is a jointing interface; while the other end opposite to the coaxial direction of the jointing interface is an assembly interface; and a hard sleeve ring is integrally formed outside the assembly interface; after the core wire of the RF coaxial semirigid cable is welded on the inserting needle, the core wire penetrates the assembly interface and is fixedly connected with the plug assembly; the utility model is characterized in that a baffle is arranged between the inserting needle and the outer conductor and the insulating layer of the RF coaxial semirigid cable. After the assembly structure is applied, the welding process of the core wire of the coaxial cable and the inserting needle can be spaced by the baffle, thus avoiding the short circuit of the electrical connection formed between the outer conductor and the inserting needle caused by the expansion and deformation of an insulator, and improving the transmission accuracy of the whole RF cable.
Description
Technical field
The utility model relates to a kind of connector construction, relates in particular to a kind of package assembly of radio frequency connector.
Background technology
Radio frequency coaxial-cable package assembly (hereinafter to be referred as assembly) is with radio frequency (RF) coaxial connector and radio frequency coaxial-cable, is connected by certain mode, constitutes the necessary part of one section transmission line jointly.The user need carry out necessary understanding to radio frequency coaxial-cable and radio frequency (RF) coaxial connector when selecting cable assembly, the understanding of cable should comprise physical dimension, mechanical performance, frequency of utilization, decay etc., and the understanding of connector should comprise the structure, interface connected mode, frequency of utilization scope of connector etc., selects suitable connectivity scenario according to own needs again.Because the kind and the structure of cable and connector are various, performance is different, it is multiple wherein just to be divided into semi-rigid cable, flexible cable etc. with regard to the kind of its cable, so the also corresponding derivation of its connected mode goes out diversity, comprises straight formula, curved formula, welding, crimping, the multiple mode of combination mutually such as be spirally connected.
In the operation of reality, the heart yearn of coaxial cable is realized with being connected by welding of plug combination body in assembling process at the straight formula package assembly of wherein comparatively common semi-rigid cable.Particularly, these plug combination body 1 one ends are docking port 12, and the other ends axially relative with docking port 12 are the assembling interface, and outside the assembling interface the integrated hard collar 11 that is formed with; After heart yearn 31 welderings of radio frequency coaxial semi-rigid cable 3 are connected on the contact pin 2, pass assembling interface and plug combination body 1 Joint.But, conventional radio frequency cable 3 with after contact pin 2 welds mutually again with the process of plug combination body 1 welding in, tend to because the control of weld time is forbidden to cause the insulator dilatancy of radio frequency cable 3, make outer conductor and contact pin form and electrically connect short circuit, thereby influence the transmission accuracy of whole radio frequency cable.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is: provide a kind of radio frequency coaxial semi-rigid cable straight formula package assembly, insulator expanded to the influence of radio frequency cable transmission performance when the straight formula of present this coaxial cable of solution was assembled.
Purpose of design of the present utility model, its implementation be by:
The straight formula package assembly of radio frequency coaxial semi-rigid cable, relate to plug combination body, contact pin and half coaxial cable just, described plug combination body one end is a docking port, and the other end axially relative with docking port then is the assembling interface, and outside the assembling interface the integrated hard collar that is formed with; After the heart yearn weldering of radio frequency coaxial semi-rigid cable is connected on the contact pin, pass assembling interface and plug combination body Joint, it is characterized in that: have a partition between the outer conductor of described contact pin and radio frequency coaxial semi-rigid cable, the insulating barrier.
Further, described partition thickness is 1～2mm.
Further, described contact pin is provided with and is used for the contact of welding mutually with the plug combination body; The hard collar inboard of described plug combination body is provided with and is used for the contact of welding mutually with cable outer conductor.
After using the described package assembly of technical solutions of the utility model, the process of being welded of coaxial cable core wire and contact pin can separate by partition, avoid insulator outer conductor that dilatancy causes and contact pin to form the situation that electrically connects short circuit, improved the transmission accuracy of whole radio frequency cable.
Description of drawings
Fig. 1 is the decomposing schematic representation of the utility model package assembly;
Fig. 2 is the schematic appearance of the utility model package assembly coaxial semi-rigid cable;
Fig. 3 is the partial sectional view after the assembling of the utility model package assembly is finished.
Embodiment
Purpose, feature and the advantage of the straight formula package assembly of the utility model radio frequency coaxial semi-rigid cable will specifically describe in conjunction with respective drawings further by the following examples, to deepen the understanding to this case innovation essence.
As shown in Figure 1 to Figure 3, be partial sectional view after the schematic appearance of decomposing schematic representation, coaxial semi-rigid cable of the utility model package assembly and assembling are finished respectively.As seen from the figure, the straight formula package assembly of this radio frequency coaxial semi-rigid cable relates to plug combination body 1, contact pin 2 and the half firm coaxial cable 3 of radio frequency connector.Wherein
These plug combination body 1 one ends are docking port 12, and the other ends axially relative with docking port 12 then are the assembling interface, and outside the assembling interface the integrated hard collar 11 that is formed with, these hard collar 11 inboards are provided with and are used for the contact 111 of welding mutually with cable outer conductor; This contact pin 2 is the hollow open shape, which is provided with to be used for the contact 21 of welding mutually with plug combination body 1; This radio frequency coaxial semi-rigid cable 3 is made of the heart yearn 31 of internal layer, outer field outer conductor and insulator therebetween, and outermost layer is coated by insulation sheath.In this straight formula package assembly, for when assembling that contact pin 2 and cable 3 is spaced apart, package assembly of the present utility model comprises that also a thickness h is the partition 4 of 1～2mm.
The package assembly of present embodiment is when assembling, at first to this radio frequency coaxial semi-rigid cable 3 as requested size carry out wire stripping and handle, remove cable outer conductor and insulation sheath on the nominal length, and remove the burr on inner wire end and the outer conductor, so that the high zygosity of the operation that is welded; Then with the heart yearn 31 of cable 3 in socket pack into behind the partition 4 and be welded on the contact pin 2; Then cable 3 is stretched in the plug combination body 1 in the lump together with contact pin 2, plug combination body 1 is fixed by positioning fixture, and by contact pin set contact 21 and the solid welding of plug combination body; At last, the inboard set solder contacts 111 of the hard collar 11 are welded mutually with the outer conductor of cable 3, and removal more than scolding tin can finish the assembling of radio frequency coaxial semi-rigid cable.
Obviously, the enforcement of the utility model package assembly, make the process of being welded of coaxial cable core wire and contact pin to separate, avoided insulator outer conductor that dilatancy causes and contact pin to form the situation that electrically connects short circuit, improved the transmission accuracy of whole radio frequency cable by partition.
