Description
Technical field
The utility model relates to a kind of cable connecting arrangement, belongs to the cable connector technical field.
Background technology
Cable TVs etc. use coaxial cable to transmit signal usually; the center of coaxial cable is provided with cored wire conductor; the periphery of cored wire conductor is coated with insulating barrier, screen and external protection from inside to outside successively, and screen is divided into the layer of metal foil that is positioned at internal layer and is positioned at outer field metal knitted twisted wire layer.Present coaxial cable connector comprises the attaching nut; lining core pipe and C type clip; one end of lining core pipe is a conical head; the other end is provided with outward flange; the attaching nut is socketed on the outward flange of lining core pipe; the external protection of coaxial cable; screen and insulating barrier are clipped a part in succession; expose cored wire conductor; make the termination of coaxial cable be the stairstepping distribution from inside to outside; cored wire conductor; insulating barrier inserts in the lining core pipe together with the taper head end of layer of metal foil from lining core pipe; cored wire conductor stretches out from attaching nut's center; metal knitted twisted wire layer and external protection are enclosed within outside the lining core pipe; C type clip is stuck in outside the external protection; by specific purpose tool the back locking is tightened up in the open end of C type clip; thereby external protection is fastened on the outer wall of lining core pipe; after this, can the radio-frequency terminals of this coaxial cable with other coaxial cables or electric equipment be linked to each other by the attaching nut.This coaxial cable connector, side at C type clip is tightened up, make the outer tube distortion that is squeezed, annular gap between outer tube and the lining core pipe becomes inhomogeneous, can not guarantee all and serving as a contrast the core pipe week and contacting well of metal knitted twisted wire layer, cause shielding bad that loss of signal is big, transmit instability, be subject to disturb; In addition, the contact area between C type clip and the external protection is less, blocks to such an extent that tension damages external protection easily, blocks too loosely then to come off easily, make connect unreliable.
The utility model content
The utility model provides a kind of external bushing squash type coaxial cable connector, and is unreliable to solve the connection of prior art standard coaxial cable, shields bad problem, and it is reliable that coaxial cable is connected, and shielding is good.
For solving above technical problem; the technical solution of the utility model is; a kind of external bushing squash type coaxial cable connector is provided; comprise attaching nut and lining core pipe; one end of lining core pipe is a conical head; the other end is provided with outward flange; the center of coaxial cable is provided with cored wire conductor; the periphery of cored wire conductor is coated with insulating barrier from inside to outside successively; layer of metal foil; metal knitted twisted wire layer and external protection; cored wire conductor; insulating barrier inserts in the lining core pipe together with the taper head end of layer of metal foil from lining core pipe; cored wire conductor stretches out from attaching nut's center; metal knitted twisted wire layer and external protection are enclosed within outside the lining core pipe; the periphery of external protection is provided with outer tube; outer tube has a center line with lining core pipe, and an end and the attaching nut of outer tube flexibly connect by draw-in groove, and the outside of the outer tube other end is provided with lock sleeve; the inner periphery of lock sleeve is provided with type conical bench, and type conical bench is pressed on external protection and metal knitted twisted wire layer on the lining core pipe.
Adopt above structure, metal knitted twisted wire layer and external protection are pressed on the lining core pipe equably in the be locked type conical bench of cover of wholecircle Zhou Fangxiang, and the area that is squeezed is bigger, easy damaged not, connect reliable and shielding good.
