The corresponding crimping position of crimping is crossed, cable shield is in close contact with adapter outer conductor, realize adapter outer conductor with electricity
The connection of cable screen layer.Cable shield and outer conductor tail end face directly contact, if cable is repeatedly curved in use
At folding wiring, contact site is acted on by frictional force, and as outer conductor metal end face is more sharp, easily causes electricity at the stress
Cable shields fault rupture, causes loose contact, affects signal transmission, it is impossible to meet the requirement of data transfer.
Utility model content
The purpose of this utility model is the shortcoming for overcoming above-mentioned prior art, there is provided a kind of microminiature of connecting cable is penetrated
Frequency coaxial connector.The screen layer for solving microminiature radio frequency coaxial connector institute connection cable is easily broken off, and improves connection
The reliability of device, improves the reliability of data transfer.
The purpose of this utility model is by the following technical programs solving：
The microminiature radio frequency coaxial connector of this connecting cable, including shell, arrange exhausted in cavity inside the housing
Edge, one end of insulator stretch out shell, and the centre of insulator is provided with endoporus, and one end periphery of shell is cased with compression bonded line
Folder, develops between jointing clamp and shell.
Further, also reside in the characteristics of this utility model：
The afterbody of wherein insulator is provided with for limiting the anti-jumping mechanism that insulator and shell are mutually shifted.
Wherein anti-jumping mechanism is the boss arranged on insulator.
The inwall of wherein away cavity is provided with the groove matched with boss.
Wherein boss is to be provided with first between the press-fit structure and barb, and press-fit structure and barb arranged on insulator
Draw-in groove.
The periphery of wherein shell is additionally provided with the back-up ring of fastening shell.
Its guide ring is circlip, and circlip is arranged in the second draw-in groove on shell.
The section that wherein jointing clamp crimps after being integrated with shell is polygon.
The beneficial effects of the utility model are, inner wire and cable core by being welded into one, insulator endoporus with
Cable insulation coordinates tight, and inner wire will not occur disconnected with the joint of cable core because of the shear stress effect by radial direction
Split, reliability is high；And the afterbody of insulator stretches out shell, the end face of shell does not contact screen layer, and insulator is tight with screen layer
Contiguity is touched, and cable shield is greatly reduced by shearing, is improve the reliability of data transfer.
Further, anti-jumping mechanism is set on insulator, and housing peripheral arranges chuck, makes the position of insulator solid
It is fixed, it is difficult to free play；Store in the environment of wider range, or use under temperature environment jumpy, insulation
Son can not spin off from shell after expanding with heat and contract with cold.
Further, shell, cable shield and jointing clamp crimping is integrated, and the section of crimp body is polygon
Shape, reduces the gap between jointing clamp and shell, can clamping cables screen layer, make cable shield by shearing subtract significantly
Little, reliability is improved.
