Description
Technical field
The invention belongs to the radio frequency (RF) coaxial connector category, relate to a kind of novel solder type cable connector specifically, can be widely used in the communication system of third order intermodulation requirement.
Background technology
[0002] along with the development of communication system and the raising of mass of system, the measurement of passive intermodulation is more and more paid attention to, third order intermodulation distortion can reduce the performance of communication system.The passive intermodulation distortion of CA cable assembly is to be caused by its inner non-linear factor.When receiver receives useful signal; If there are two interference signals to act on receiver inlet simultaneously; And can be added on the resonance amplifier of receiver effectively; Because device property non-linear will cause the interaction between these two signals, produce a kind of newborn interference signal close so with the useful signal frequency.At this moment receiver also is being mingled with whistle cry and mixed and disorderly back drop simultaneously except the sound of hearing useful signal.It is this because the distortion that the effect of intermodulating causes useful signal between disturbing is called Intermodulation Interference.In a desirable linear system, the characteristic and the input signal of output signal are on all four; And in non linear system, the output signal is compared with input signal and has been produced amplitude distortion.In the modern communication system, what engineers was concerned about most is third-order intermodulation product, thereby accepts frequency range to receiver generation interference because these useless frequency components tend to fall into.Radio frequency co-axial cable subassembly is regarded as linear unit usually, but pure linear unit is non-existent.Total some non-linear factor exists between connector and cable, and these non-linear factors are normally because surface oxide layer or loose contact caused.
Summary of the invention
In order to achieve the above object, the invention provides the novel solder type cable connector that a kind of third order intermodulation stable and consistent, high qualification rate are provided.
In order to address the above problem, the present invention realizes through following technical scheme:
The present invention is a kind of novel solder type cable connector, comprises insulator, inner wire and outer conductor; An outer conductor and a swivel nut connect and fix, and outer conductor connects the homologous series connector, and insulator is pressed into said outer conductor; The outer conductor welding of an outer conductor and a coaxial cable, the inner wire welding of inner wire and coaxial cable, a passage A is run through in the inside of insulator; Inner wire inserts in the passage A, at the afterbody stube cable position of outer conductor channel B is arranged, in channel B; The outer conductor of coaxial cable and the outer conductor of connector are accomplished and are welded to connect, and on the base plane of passage, are provided with an anti-stannize boss, the arranged outside of the inner wire of coaxial cable insulating barrier.
Further improvement of the present invention is: anti-stannize boss embeds the insulating barrier on the coaxial cable, forms a circular surfaces at anti-stannize boss and channel B, between circular surfaces and anti-stannize boss, a Xi Quan is set all.
Further improvement of the present invention is: anti-stannize boss is the taper seat of projection.
Passage baseplane, described outer conductor welding cable position is provided with an anti-stannize boss, prevents problems such as tin trickling inequality, seepage, rosin joint in connector and the cable welding process.Leave the space between anti-stannize boss and outer conductor, a complete Xi Quan can pack into.The key position that contacts with cable at connector adds Xi Quan in advance; Can control the consistency of soldering tin amount on the one hand; Next avoided former side weld Bian Jiaxi to cause like the trickling of the inequality of trickling, tin less than contact site, rosin joint, weld time defective such as long scald cable; Reserved anti-stannize boss just, made Xi Quan after fully melting, change performance in the also unlikely infiltration connector cavity, so both guaranteed good welding effect; Do not influence its voltage standing wave ratio performance again, improved welding efficiency and qualification rate.
Compared with prior art, the present invention is simple in structure, effectively improves the connector of three rank qualification rates, and the novel solder type cable connector of a kind of third order intermodulation stable and consistent, high qualification rate is provided.

Embodiment
In order to deepen to understanding of the present invention; To combine accompanying drawing and embodiment the present invention to do further detailed explanation below; This embodiment only is used to explain the present invention, protection range of the present invention is not constituted to limit, and these accompanying drawings are the sketch map of simplification; Basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
Shown in Fig. 1-3, the present invention is a kind of novel solder type cable splicing device, comprises insulator 5; Inner wire 2 and outer conductor 3; A said outer conductor 3 and a swivel nut 4 connect and fix, and said outer conductor 3 connects the homologous series connector, and said inner wire 2 is welded to connect with the inner wire 61 of coaxial cable 6; Insulator 5 is pressed into outer conductor 3 and for inner wire 2 necessary support and insulating effect is provided; Outer conductor 3 is welded to connect with the outer conductor 63 of coaxial cable 6; Swivel nut 4 connects and fixes the back with outer conductor 3 and is connected with the homologous series connector, and insulator 5 inside are run through by a passage A, and inner wire 2 can insert in the passage A of insulator smoothly.Connector outer conductor 3 afterbodys connect the cable position has a channel B, and the outer conductor 63 and the connector of coaxial cable 6 are accomplished in channel B and be welded to connect.Shown in be provided with an anti-stannize boss 32 on the channel B base plane 31; Anti-stannize boss 32 is protruding taper seat; After coaxial cable 6 and connector normally plug together installation; Anti-stannize boss 32 taper seats can embed the insulating barrier 62 of cable, can effectively deaden tin circle 1 like this and after high temperature melting, flow to outer conductor 3 inner die cavities, stop bad withstand voltage because of the conducting of tin stream causes of connector inner and outer conductor; Anti-stannize boss 32 forms circular surfaces 33 with channel B, with circular surfaces 33 tin circle 1 is set at anti-stannize boss 32.Insert the coaxial cable that welds inner wire 26 in connector outer conductors 3 channel B, the passage A that inner wire passes insulator 5 forms fixing, and the end face of the outer conductor layer 63 of coaxial cable 6 and insulating barrier 62 contacts with tin circle 1, anti-stannize boss 32 simultaneously simultaneously.Beginning fusing through induction welding equipment heating tin circle 1, cable will continue to put in outer conductor 3, on arrival channel B base plane 31, form fixing.
As stated, the fusion between anti-stannize boss 32 and channel B circular surfaces 33 of tin stream makes cable outer conductor layer 63, connector outer conductor 3 flow abundant welding with tin and reaches best welding effect.All solidify in tin amount, tin stream position, weld time like this and guaranteed welding reliability to greatest extent, reach stable, the consistent high qualification rate target of third order intermodulation.
