Description

Neck bush tightens up the formula 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 neck bush to tighten up the formula 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; provide a kind of neck bush to tighten up the formula coaxial cable connector; 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 attaching nut is socketed on the outward flange of lining core pipe; 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 outside of lining core pipe is provided with outer tube; outer tube is connected as a single entity with lining core pipe and has a center line; the outside of outer tube is provided with lock sleeve; the inwall of lock sleeve is provided with lining; the end face in opposite directions of lining and outer tube fits; one end of lock sleeve is socketed in the end of outer tube; the inner periphery of the other end is provided with type conical bench, and type conical bench is pressed on lining on the external protection.

Adopt above structure, the type conical bench of lock sleeve is inwardly pushed lining, and lining is pressed on metal knitted twisted wire layer and external protection on the lining core pipe equably at wholecircle Zhou Fangxiang, and connection is reliable and shielding is good.

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 sign circles, 3 lining core pipes, 4 outer tubes, 5 linings, 6 lock sleeves, 7 external protections, 8 metal knitted twisted wire layers, 9 layer of metal foil, 10 insulating barriers, 11 cored wire conductors.

Embodiment

As shown in Figure 1, neck bush of the present utility model tightens up the formula coaxial cable connector, comprise attaching nut 1, lining core pipe 3, outer tube 4 and lock sleeve 6, one end of lining core pipe 3 is a conical head, the other end is provided with outward flange, attaching nut 1 is socketed on the outward flange of lining core pipe 3, the outside of lining core pipe 3 is provided with outer tube 4, outer tube 4 is connected as a single entity with lining core pipe 3 and has a center line, and the outside of outer tube 4 is provided with lock sleeve 6, and the root of outer tube 4 is provided with sign circle 2, the inwall of lock sleeve 6 is provided with lining 5, lining 5 fits with the end face in opposite directions of outer tube 4, and an end of lock sleeve 6 is socketed in the end of outer tube 4, and the inner periphery of the other end is provided with type conical bench.

As shown in Figure 2, the center of coaxial cable is provided with cored wire conductor 11, and the periphery of cored wire conductor 11 is coated with insulating barrier 10, layer of metal foil 9, metal knitted twisted wire layer 8 and external protection 7 from inside to outside successively.During connection; the external protection 7 of coaxial cable, metal knitted twisted wire layer 8, layer of metal foil 9 and insulating barrier 10 are clipped a part in succession; expose cored wire conductor 11; make the termination of coaxial cable be the stairstepping distribution from inside to outside; cored wire conductor 11, insulating barrier 10 insert in the lining core pipe 3 together with the taper head end of layer of metal foil 9 from lining core pipe 3; cored wire conductor 11 stretches out from attaching nut 1 center, in metal knitted twisted wire layer 8 and external protection 7 annular chamber between lining core pipe 3 and lining 5.

As shown in Figure 3; after coaxial cable was in place, lock sleeve 6 was to the axial compression of attaching nut's direction, and the type conical bench of lock sleeve 6 is progressively inwardly pushed lining 5; lining 5 inwardly shrinks until external protection 7, metal knitted twisted wire layer 8 being pressed on the lining core pipe 3, makes coaxial cable be able to firm connection.
