Description

Interior curved squash type coaxial cable connector

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 interior curved squash type coaxial cable connector, and is unreliable to solve the connection of prior art standard coaxial cable, shields bad problem, and coaxial cable is connected reliably, and shielding is good.

For solving above technical problem; the technical solution of the utility model is; a kind of interior curved 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; one end and the attaching nut of outer tube flexibly connect by draw-in groove, and the circumference of outer tube is provided with aduncate annular groove, and annular groove is pressed on external protection and metal knitted twisted wire layer on the lining core pipe.

As improvement of the present utility model, the outer face of lining core pipe outward flange is provided with sealing ring.

Adopt above structure, metal knitted twisted wire layer and external protection are pressed on by the annular groove on the outer tube on the lining core pipe equably at wholecircle Zhou Fangxiang, and connection is reliable and shielding is good.Sealing ring on the lining core pipe outward flange outer face, the attaching nut is connected with other coaxial cables compress after, can prevent from that rainwater from infiltrating to serve as a contrast the core pipe, avoid coaxial cable to corrode.

Description of drawings

Fig. 1 inserts preceding structural representation for the utility model coaxial cable;

Fig. 2 is the structural representation of the utility model coaxial cable after inserting;

Fig. 3 is the structural representation of the utility model coaxial cable after compressing.

Among the figure: 1 attaching nut, 2 sealing rings, 3 lining core pipes, 4 outer tubes, 5 annular grooves, 6 external protections, 7 metal knitted twisted wire layers, 8 layer of metal foil, 9 insulating barriers, 10 cored wire conductors.

Embodiment

As shown in Figure 1, curved squash type coaxial cable connector in of the present utility model, comprise attaching nut 1, lining core pipe 3 and outer tube 4, one end of lining core pipe 3 is a conical head, and the other end is provided with outward flange, and the outer face of outward flange is provided with sealing ring 2, outer tube 4 has a center line with lining core pipe 3, one end and attaching nut 1 flexibly connect by draw-in groove, and attaching nut 1 can freely rotate in the end of outer tube 4, and the circumference of outer tube 4 is provided with aduncate annular groove 5.

As shown in Figure 2, the center of coaxial cable is provided with cored wire conductor 10, and the periphery of cored wire conductor 10 is coated with insulating barrier 9, layer of metal foil 8, metal knitted twisted wire layer 7 and external protection 6 from inside to outside successively.During connection; the external protection 6 of coaxial cable, metal knitted twisted wire layer 7, layer of metal foil 8 and insulating barrier 9 are clipped a part in succession; expose cored wire conductor 10; make the termination of coaxial cable be the stairstepping distribution from inside to outside; cored wire conductor 10, insulating barrier 9 insert in the lining core pipe 3 together with the taper head end of layer of metal foil 8 from lining core pipe 3; cored wire conductor 10 stretches out from attaching nut 1 center, in metal knitted twisted wire layer 7 and external protection 6 annular chamber between lining core pipe 3 and outer tube 4.

As shown in Figure 3, after coaxial cable is in place, outer tube 4 is carried out axial compression; inwardly further flexural deformation of annular groove 5 on the outer tube 4; internal diameter dwindles, and its top is pressed on external protection 6, metal knitted twisted wire layer 7 on the lining core pipe 3, makes coaxial cable be able to firm connection.
